Software developers tend to play by the rules more often than not. However, sometimes a code can be sloppy and disorganized and that doesn’t make anyone’s life any easier. code According to the ubiquitous , This means that the root of all your problems lies in only a few bad coding practices. Pareto principle 80% of consequences come from 20% of the causes. Below are 4 deadly sins of programming: Typos in Your Code Spelling and grammar deficiencies can impact your overall programming skills. There’s nothing more infuriating than showing off your work to your boss and seeing a spelling error. It’s like waving a red flag at a bull. One solution to this is to work on a decent ) that has coloring. Furthermore, you may pick easy-to-spell variables and function names just to be on the safe side. integrated development environment (IDE syntax Too Many Cooks Let’s say, a team of developers works on a project over a few months or years. During this time everyone continues to ‘twist and turn’ the code and software design scope. This, in turn, creates incomprehensive coding structures and GOTO statements that contradict with the code’s and . scopes models You can avoid a tangled web of programming source code by leveraging lightweight , implementing layers, as well as giving unit testing some added traction. frameworks Not Commenting on Your Code Should a good code speak for itself? Only if you include comments. We feel your pain. Nobody has the time and aspiration to narrate their code after hours of debugging or problem-solving. Nevertheless, you shouldn’t leave your code without a translation. Sometimes, what looks simple to you might look like a to other developers. Klingon Always write at least a one-liner to comment on classes, methods, and other parts of your work. You’re already testing the limits of your brainpower, so don’t make it any harder by not leaving reminders for later.

Furthermore, let’s not forget the fact that the log history shows you exactly who else has played in the . sandbox Have you ever: Lost code or had an antiquated backup? Had to keep up multiple versions of a product? Wanted to see the difference between your code versions? Needed to provide global access to your team? Version control will get you covered any time you need recovery, coherent , or improved visibility. It’s an elegant tool for a civilized world. collaboration Feature Flagging Trust us, not using feature flagging when rolling out new functionalities to your users is the deadliest sin of them all. With feature flagging, new features can be deployed without making them visible to users. Likewise, if you need data migration (for example), feature toggles will prevent your work from impacting the rest of the team or destabilizing the codebase.

Just to stay in business. How can you make sure that your avant-garde idea pans out? Below are the influential trends empowering QA teams to perform even better in 2021. Limitless-ish Although hasn’t yet embraced its full potential (no cybernetic androids for now), it is soon to become a tester’s BFF. Artificial Intelligence AI-based testing platforms are helping companies perform testing in smarter and more efficient ways. Here’s how machine intelligence is making a dent in the : testing market Machine-written test cases; Automating test generation; API Automated ; UI testing Creating automated tests more reliable, and others. But that’s not even half of the superpowers it possesses. Eventually, the unbeatable combo of NLP, ML, and reasoning will help developers minimize their direct participation in the process and automate testing completely. It Fits Modern approaches are also merging principles of with QA into QAOps. DevOps This novel approach inherits the best from projects and combines it with the best from the QA process. CI/CD Thus, instead of having a minor role, QAOps introduces quality assurance into the whole software development lifecycle. It keeps the testing team constantly engaged and helps them fix bugs sooner, boosting the value delivered to users. Interconnected Future This year, the will continue its exponential growth accelerated by 4G and network standards. Internet of Things 5G This means that the projected surge in the number of IoT devices will increase the need and scope of IoT testing as well.

But what if your failures resulted in profound havoc at banks, airlines, and companies, creating billions of dollars worth of as well as devastating disruption? damage Chills. A wise person learns from the mistakes of others. So let’s accumulate some wisdom and go over the biggest failures in the history of software. Ya, Boo Yahoo has had a notable history of both and hacker attacks. data breaches In December 2014, Yahoo's security team reported that hackers had obtained the credentials of at least Yahoo accounts. The hack took place in 2014 but was only made public in 2016. 500 million Thankfully, sensitive financial data like bank accounts and passwords were left uncorrupted. The question remains: Why did it take so long to confirm the hack and its scale? Facebook Takes a N’app In 2019, Facebook suffered a that tampered with the Facebook family of apps, including , , and . severe outage Instagram WhatsApp Messenger The company was back on track after 24 hours and blamed the issue on ‘routine maintenance.’ As Facebook reports, it was a change that triggered a cascading series of issues. server configuration Now let’s imagine the magnitude of frustration when business owners couldn’t access their digital Holy Grail. Glitch Airways In November 2019, a computer glitch left stuck on the ground for a maximum of 24 hours. The delays and further cancellations had been caused by what the describes as a "technical issue." thousands of British Airways passengers airline But that was not an isolated incident. In August of the same year, caused the cancellation of more than 100 flights and torpedoed the plans of 35,000 passengers into disarray. another IT glitch Oh, talk about chaos. Github et tu? Yep, even super techies are not invincible. On January 31st, 2017, GitHub suffered a major backup restoration failure for one of its products: The online service . GitLab.com The failure was the result of accidental data removal from their primary database server. The aggravating factor was that the backups had not been made for a while due to a configuration error. As a result, the company lost some production data including modifications to database data such as projects, comments, user accounts, and others. A total of 300 GB of customer data was lost. Amazin' Outage Thousands of online services store their data in the data centers of AWS. This means that even a small tech glitch can take down Netflix, Slack, Airbnb, Pinterest, Reddit, Quora, and even NASA. Hence, many of them were impacted during a prolonged AWS outage that took place in November 2020.

A Ring of Failure

Chaos has become a symptom of the tech world. Every day, thousands of developers are putting out fires at work and getting caught up in one crisis after another. The better part of those fires have been lit by the rise of and . The popularity of those advancements is at an all-time high, yet failures continue to be prominent and complex. microservices distributed cloud architectures Downtime Jitters According to an IHS Markit survey, the cost of downtime for 400 companies hit a collective per year. This is a staggering figure. $700 billion In March 2015, a 12-hour Apple store outage cost the company $ . 25M In May 2017, one outage stranded tens of thousands of British Airways (BA) passengers and resulted in a $102.19M loss. In December 2020, a large-scale outage took down YouTube, Gmail, and Google Assistant for around an hour. There were a lot of pocket holes that month. We all need a magic pill to alleviate this headache —waiting for your service to crash is a bleak option. Let’s do it the Netflix way and chill during deployment. Play Destroy Welcome to chaos engineering - a place where mistakes are intentional and failures are embraced. Its history dates back to 2010 when the Netflix Eng Tools team created Chaos Monkey to test the resilience of its IT infrastructure. Today, chaos engineering is ‘celebrating failure’ to help engineers and systems build muscle memory and maintain more resilient complex systems. Vaccinate Against Downtime In layman’s terms, chaos engineering is the process of things on purpose. hacking Just like a vaccination, you inject or to trigger an immune response within the system. latency CPU failure In this case, our main goal lies in identifying hidden problems that may wreck production. As a сhaos engineer, you test the system's ability to handle real-world problems - server errors, traffic jumps, corrupted messages - in a series of controlled experiments. Break Things Strategically To stress your system out, you need to follow a four-step process: Develop a profound understanding of a system so that you are aware of what it looks like during normal functioning. This state will serve as a measurable variable. Define the steady-state of the system. Choose the damaging action you want to enact. Simulate realistic scenarios. Replicate real-life problems that have previously occurred in your system. For example, if traffic spikes caused havoc a few months ago, opt for bugs that mimic those affects. Build a hypothesis around steady-state. Keep tabs on your system while the bug is attacking it. Focus on key metrics, but don’t forget to assess the entire system. Measure the impact. Safeguard the infrastructure by coordinating developer teams and business units. Furthermore, you should start small and build up as you gain confidence in a system. Minimize the blast radius. Finally, you’ll have one of the two outcomes. You either confirm the resilience of the system, or you find a weak point to eliminate. Invalidate your hypothesis. Pro tip: Run chaos experiments in production to replicate the real state of things. If you perform chaos testing during staging or integration, you won’t build a real vision of how the system in reacts. production Embrace the Art of Chaos Awesome! We’ve successfully shattered your application using controlled chaos and debunked the concept of chaos engineering. Next, you would want to right the wrongs to make your system invincible.

How Stack Overflow Inspires Coders

Photo by Javardh on Unsplash Cryptocurrencies have emerged as a reliable tool allowing online users to control their own money without the participation of outsiders. It is decentralized and anonymous cryptocurrencies that are putting an end to the era of offline banks. In 2021, two ordinary online users can perform any financial transactions without the participation and control of third parties, which ensures the security and confidentiality of the process. However, some coins allow you to register the details of all transactions in the blockchain, and there are others where it is impossible to do so: no one knows either the details of the transactions or the names of users who perform them. These are called privacy coins. What are Privacy Coins? Privacy coins are anonymous peer-to-peer decentralized systems that are a unit of calculation within the network. It is anonymous cryptocurrencies that ensure the protection of financial transactions throughout the network. From business people who care about confidentiality and speed of processes to ordinary internet users who want to ensure the inviolability of their personal life. Privacy crypto coins are necessary for everyone who cares about their security: Nevertheless, the idea of anonymity of cryptocurrencies is subject to huge criticism. This is due to financial regulators who insist on using AML/KYC requirements. However, such openness of the blockchain means that anyone, including government agencies, trusted persons, hackers, or just savvy internet users will be able to track any financial transaction and calculate the identity of the cryptocurrency holder. Therefore, many developers realized the need to create truly anonymous cryptocurrencies to provide users with maximum privacy for financial transactions. What are these anonymous crypto coins? Here’s the privacy coins list. The Best Privacy Coins for Secure Use Crypton (CRP) and Utopia CRP Stablecoin (U USD) is the main monetary unit of the Utopia P2P ecosystem. Crypton (CRP) The fact that a large and private ecosystem backs the coin makes it stand out among others and puts it in the first place in our rating. Utopia P2P is an anonymous, decentralized ecosystem that includes several multifunctional tools for messaging, data transmission, surfing, mining, and conducting financial transactions. It was developed by The 1984 Group. The team stands for the security and privacy of the data of every internet user. CRP is a privacy coin and an internal cryptocurrency of the anonymous ecosystem. It provides anonymous financial transactions that are not recorded in the blockchain in any way – so it is impossible to track the payment history. In addition, there is no available metadata. No other cryptocurrency provides such a level of tracking-proof transactions. Crypton is a hidden gem that ensures users' privacy. Recently, another crypto project of the ecosystem has been developed – the (U USD). The U USD is an anonymous, secure, private, and low-cost payment method designed to maintain 1:1 parity with the U.S. dollar. Utopia CRP stablecoin It provides secure financial transactions, tax-free savings, the lowest fees on the market, independence from political or social organizations, the absence of KYC requirements, and more. The liquidity of the Crypton and U USD is supported by various market algorithms on different exchanges, including the Utopia internal exchange. Monero (XMR) is one of the most secure and confidential cryptocurrencies. It is based on the CryptoNote encryption protocol. It was released in 2012 by the anonymous development team of Nicolas van Saberhagen. Monero This crypto coin is top-rated in the darknet. As a result, law enforcement officers from different countries have repeatedly tried to figure out the mechanism of its operation. Unfortunately, they could not even determine the number of transactions, much less the personal data of users. The Monero mechanism to protect users is based on complex cryptographic technologies, such as Kovri, Ring CT, and Stealth. However, since the Monero blockchain has much more effective protection than other altcoins, its "rich inner world" remains closed. It is not surprising that the malware creators for hidden mining prefer to mine Monero than similar coins. Dash Evan Duffield, the ideologist of , first expressed ideas about creating an "improved version" of Bitcoin back in 2010. Dash The developer of Dash believed that the first cryptocurrency lacked anonymity and more than once suggested changing the Bitcoin blockchain. Faced with resistance from the creators of Bitcoin, Duffield developed the concept of Xcoin in 2013. After two rebrands, the coin became known as Dash. Dash is another popular cryptocurrency with the simplest anonymity function, working in a two-level structure. Miners mine coins and guarantee the network's security, and user masternodes provide anonymity through Private Send technology. All transactions are divided into many parts, mixed, and become indistinguishable from each other. Dash platform users have the opportunity to transfer funds almost instantly through the InstantSend service. Verge (XVG) It was released in 2014 by a crypto enthusiast under the nickname Sunerok. It is based on encryption protocols such as Wraith and Tor. is an anonymous cryptocurrency focused on confidentiality. Verge It can keep all transactions closed, anonymous, and completely inaccessible for tracking. Verge uses Tor and I2P to ensure the complete anonymity of its users and their funds. As experts emphasize, the Tor proxy system encrypts traffic and passes it through many computers. The add-on from the private I2P network makes it even more difficult to identify users. The coin has several unique features, but the most valuable is the combination of a high degree of privacy with the speed of confirming transactions. Komodo (KMD) was invented and launched by an anonymous crypto enthusiast under the nickname jl777 in 2016. The coin encryption protocol is Delayed Proof of Work (dPoW). Komodo One of Komodo's secure cryptocurrencies is actually a fork of Zcash. According to experts, using zero-proof and the recently introduced Delayed Proof of Work (dPoW) protocol, Komodo provides its users with complete anonymity and an additional level of security. Zero-proof guarantees that all transactions, the identification of the sender and recipient on the Komodo platform, and the amount are not visible to an outside observer. In practice, this means that Komodo additionally signs its blocks in the Bitcoin blockchain, which makes it almost impossible for third-party penetration and hacking. Coin owners have a choice between public and anonymous transactions. In the first case, traces of the transaction can be found in the blockchain; In the second, only the transaction itself is recorded. SmartCash This is a fork of the famous Zcoin cryptocurrency. The smart protocol was explicitly created to throw hackers off the trail. The idea is to introduce random data into each chain, making it impossible to track the movement of money. The main function of – which is not present in any other coin – is smart privacy. After its activation, the funds disappear from the client's account along with the history. SmartCash Still, after a couple of minutes on the same wallet, the entire amount is restored in new coins without any history. Attackers cannot track transactions or determine where they came from and what the funds were spent on. According to analysts, the activation of smart privacy costs 2% of the cryptocurrency being destroyed, but such a large-scale security measure cannot be free. This is a very high level of privacy, which automatically puts SmartCash among the leaders in the ratings for the most anonymous cryptocurrencies.

It goes without saying that this has changed our lives unrecognisably. However, the march of technological advancement goes on. Our digital world is encompassing more and more of our day-to-day lives. This has meant that a concept, previously reserved for science fiction, the metaverse, is starting to be realised. The metaverse is defined slightly differently by many investors and futurists but the core concept is generally the same. The metaverse is a . Currently of course, we are all connected through our phones, laptops, and desktops. According to the adventure captialist Matthew Ball, the metaverse will emerge as more and more products, services, and capabilities integrate and meld together. This will connect us in a way that will seem unimaginable even in today's closely linked world. framework for an extremely connected life Many, including Mark Zuckerberg, take the concept much further and see the metaverse as the point when virtual reality can replicate social interactions completely. This would mean that two people, on opposite sides of the world could meet at a virtual arcade, explore the area, and play games together. The concept of online gaming is of course nothing new. The metaverse is the idea that online interactions can integrate every other facet of our lives. NFT Technology: the Key To the Metaverse This is why the current use cases of NFTs have barely begun to scratch the surface of the technology. Everything will have to be represented in the metaverse. This means inventory to sell, objects that can be used online, and even online real estate will have to be ownable, sellable, and transferable within the metaverse. NFT technology grants holders true ownership over digital items. If you understand the security that holding a digital item on the blockchain grants a user, you'll begin to see how NFTs can shape a metaverse that encompasses society across the globe. The concept of NFTs granting ownership over digital items is already one that has been accepted by the mainstream as evidenced by the prices paid for some digital artwork. The metaverse is simply taking that concept into a virtual world. We are already seeing some NFT projects moving more and more into the realm of the metaverse. The world of blockchain gaming is seen by many as the prototype for an all-encompassing metaverse. Many of the concepts that form the metaverse have already been tried and adapted within blockchain gaming. Axie Infinity is currently the biggest gaming project in the space and one of the biggest NFT projects overall. In the game, players adopt, train, and battle Axies, creatures very similar to Pokemon. Each Axie is represented on-chain as an NFT. As the Axies get more experience they become more powerful and thus, more expensive. Not only Axies but in-game items that can be used to enhance an Axies abilities can also be purchased. Players will battle and interact with each other in the world of Axie Infinity. Essentially, Axie Infinity is a virtual world where people interact through digital items from opposite corners of the globe. It is, in some respects, its own limited version of the metaverse. Xplorer’s Studio, a soon to be released set of 10,000 NFT astronauts, is another project that's dabbling in the metaverse. An Xplorer NFT doubles as a digital ticket that will grant holders access to a suite of online tools that will help create an online persona. These tools include zoom backgrounds, an exclusive store, a digital community wallet and other special features. In addition to that and perhaps even more significant, Xplorers Studio will purchase land in a metaverse after sales of the nft have concluded. The purchasing of online land is a huge leap forward for the concept of the metaverse. It shows that value can really be extracted from online real estate and integrates yet another factor of our offline existence onto the blockchain. This commitment to pushing boundaries is exactly the ethos that Xplorer Studio is trying to cultivate both within their community and with their NFTs. The metaverse is in its very early infancy. We are only really seeing the technology that it will be built on being established. As virtual reality develops, as the internet becomes more accessible throughout the world, and as blockchain attains mass adoption, the metaverse will start to truly take shape. NFT projects are already building towards this new horizon. This article is part of The hosted by HackerNoon in partnership with Gaming Metaverse Writing Contest The Sandbox .

NFTs And The Creation Of The Metaverse

I have accepted a role at a new company since the time of writing this article. Please note that the contents of this article do not reflect the nature of my current employer. I’m a husband, father, and software engineer. I read, write, I 3D print, I play video games, and I’m a sarcastic wisenheimer.  For half of my career, I have worked at a huge Silicon Valley programming giant.  I won’t name them here, they’re not relevant, but their existence is.  When I joined the company, I had to disclose all of my side projects and websites. Then they chose which ones I could leave in production and which ones I could not. They required me to stop writing new code for anything not owned by them. They informed me that they could potentially own anything new I wrote otherwise and asked me to stop adding features to my own blog, though I could continue to write content on it. The Problem I was beyond ecstatic about the opportunity to work for this company, so I took this restriction very seriously. I stopped working on all side projects. I removed my blog (because why pay for hosting when you can’t actually work on it), and took down all other projects from production. I asked my manager about contributing to open source and was told that approvals come on a case-by-case basis, but it would likely be denied if [company] wouldn’t benefit. At this point, my employer was in full control of all of my professional development, and this is where the problem began. After six years at this company (more than half of my career), I’ve found myself looking for my next exciting opportunity. The problem is, without side projects, open-source contributions, or a blog - I’ve realized the only skills I’ve gained have been on-the-job. Granted, I have gained some amazing skills but only my specific language (PHP) and team’s chosen framework (Laravel). For the past two years, I’ve requested to be added to Python or Java projects, for opportunities to work with talented developers and gain those extra skills, but have received no traction. As I look at job postings I feel like I actually took a step backward over the past six years and need to apply to jobs far below what I am capable of, purely because I went six years with no experience outside of PHP/Laravel. The Solution So, I still take my job seriously. I still need to “not get fired.”  I still want to be taken seriously as an active developer at [company].  But I also need to enhance my skills. So, I can’t (or shouldn’t) work on any production-facing tools, how do I move forward? Well, I decided to just bite the bullet and accept the fact that I can still work on side projects, as long as they never see the light of day, so to speak. They can be built. They can be shown. I just can’t produce production-released tools or attempt to make any money off of these hobby projects.  I recreated my old blog, with a new design and URL (I had let the old one lapse and now the sharks have it) and decided to just start hacking together some bits of code to learn. This is frustrating and disappointing, to say the least, but it’s something I just have to do in order to catch up to where I really should be right now as a developer. The Idea So I decided to start a series of articles that I’ll post here in the dedicated learning space. My goal is to learn the basics of many languages. I know I, likely, won’t become as skilled in Java or Python or GO as I am in PHP, not without some work experience, but learning the basics will allow skills to translate. That’s something I’ve seen in some interviews. The comment “well your skills in PHP won’t translate here.” Of course, they will! And I’m here to prove it. Every week I’ll post a new article where we learn some basic concepts in programming. Something very simple like Declaring variables.  And we’ll do it in PHP first since that’s my core language. Then we’ll do it again in Java, and in Python, and in Go, and in Scala, and in Bash, etc. Any language I can think of that has a valid role in modern programming so that we can start to learn all languages together. The goal is to create a record of proof for myself, and anyone else who joins me in this journey, that these skills are transferrable and that we can all do many things. Stay tuned, I’ll post my first article this weekend. Happy Weekend, devs!

How Working in a Big Silicon Valley Company Stalled My Career Growth

This story is a part of of interviews. The series is intended for tech professionals contributing the most insightful Hacker Noon stories to share more about their writing habits, ideas, and professional background (and maybe a hobby or two). Hacker Noon's Meet the Writer series So let’s start! Tell us a bit about yourself. For example, name, profession, and personal interests. Hi Hackers! My name is Andrei Rotariu. I’m 36 years old and hail out of Melbourne, Australia (currently locked-down, and living with a curfew in place, yay freedom!). During the daylight hours, I’m a hardware safety guy for a large power tool company. But under the cover of darkness, I like to get involved in all manner of crypto-related stuff. I’ve done a lot of dumb experimental sh*t over the years. I blew up a laptop trying to mine this peculiar Cryptocurrency called Quarkcoin one time. Another time earned through a combination of saving, trading, and playing roulette and then mostly lost it all. I could have been retired on a yacht somewhere by now. 2 Million Dogecoin Currently, I have a blog series running called which I started on Medium and republished right here on Hacker Noon. I’ve recently moved it over to its own hosted solution so that I can focus on growth. With that, sadly I had to delete most of my posts here on HN due to duplicate content issues. Crypto Fireside Crypto Fireside started off as an experiment with an interview-style Q&A post series (hence the name Fireside). I would talk to folks from the Cryptocurrency and decentralized world about all manner of things, usually, projects they are working on, businesses, start-ups, that kind of origin/founder story thing. It’s something I personally enjoy reading and so that is how I started it off. I was impressed with a guy called Pat Walls and his StarterStory as well as being influenced in my teenage years by interviews in magazines that I read from 90’s and 00’s magazines like FHM, Readers Digest, PC World, Ralph, Australian Men’s Health, Australian Men’s Fitness, Rolling Stone and a bunch of others. I started Crypto Fireside because I noticed most of the Crypto and blockchain-related content out there usually revolved around one of two things: But here is the thing; there are real people behind those . Real people with real stories, real struggles, and real successes. That’s why I wanted to talk to them and bring those stories to the world. Money or tech. money and tech projects Interesting! What was your latest Hackernoon Top story about? As I just mentioned at the time I think when I first started republishing content, I had interviewed Christian Winter, a young German entrepreneur, about his music and lighting business and about how he was opening his venture up to Cryptocurrency through Bitcoin Cash. I from memory that one was pretty popular but because I had to remove much of my content from here on HN due to duplicate content issues I can’t say for sure now. I know that I had a couple of pieces that had received in excess of 20k-30k views. Right now, I think it is a post I wrote titled ‘ ’. No, Bitcoin Is Not Going to Fail Do you usually write on similar topics? If not, what do you usually write about? I started my writing career (paid writing) freelancing and writing funny content as a copy and content writer for online businesses and marketers. That was probably 16 or so years ago. I claimed at the time to be one of the only humor-content freelance writers on the web and would be asked to write sales pages for guys that would create creepy dating programs or gag gifts like manly scented candles with scents such as beer and cigarettes or diesel covered overalls. I’m embarrassed to say that I used to find these gigs in places like back in the day! The Warrior Forum Like most things in my life I kind of just aim in the direction that I want to go and figure the rest out as I move forward and so in a sense I kind of stumbled into writing about Cryptocurrency because of a project I fell in love with at the time. They were going to decentralize the entire world wide web and free us from the tech oligopoly. It’s called developed by a Scottish firm called Maidsafe. SafeNetwork One thing led to another, and well, here we are today. The Cryptocurrency and blockchain space feels like the early Internet days right now and so there are a lot of cool and interesting projects and people behind those projects for me to write about. The world needs to hear about these things and so there’s no end in sight for Crypto Fireside right now. In fact, it’s just the beginning. Great! What is your usual writing routine like (if you have one?) Crypto Fireside started off as a Q&A interview-style format, and so my routine had to evolve with that. Normally I would write whenever I felt inspired, I’d just get it out of my head and slowly edit and craft it when I had the time, early mornings or at night would work really well for me in the past. There’s something about those times when everyone is asleep, not just in your own home, but all around you in your city, I can’t explain it, it’s almost like the heaviness of the collective consciousness is removed or something. When I work on a story with another person, interviewing them, I had to come up with a different system and so far what I have been doing seems to work well. I usually spend some time talking or web chatting to the interviewee to get a really good grasp of what it is they do and then I will draft my questions, usually the questions are styled the same way but I do tweak them from time to time. I send the interviewee a shared doc, allow them time to fill it out, they send it back, I’ll review it and get back to them with clarifications or follow-up questions and we go from there. That is kind of the system I have been going with when I interview someone. But I also do loads of other types of content now. Satire, guides, reviews, and general commentary. I also hire writers from time to time to help me out when I don’t have the time. Above all else, the hardest thing is promoting your work but it’s also the most satisfying part of it. In the modern world of writing, you can’t just write and publish something and expect it to take off. It’s not like the good old days where you’d get picked up by a newspaper or magazine and they’d send your story out to their syndicated network and voila’. You gotta work that hustle-muscle and push your stories. The successful modern writer is also a successful marketer nowadays, this is not just my opinion. Over the years of doing this, I have learned and crafted a number of ways to distribute content. SEO of course is one of them, but it goes much further than just SEO. I use most of the social networks and I try to leverage other places like Hacker News, Reddit, Digg, and more. Being a writer in tech can be a challenge. It’s not often our main role, but an addition to another one. What is the biggest challenge you have when it comes to writing? Time! You know it’s funny I write about Cryptocurrency and talk to people about these digital tokens and things that have a perceived value and I think the most valuable ‘token’ on the planet is . It has to be. time I like to refer to this concept as . Time Tokens Time is the great equalizer. Rich, poor, black, white, it doesn’t matter what side of the train tracks you come from, who you are, where you are from, your background, the amount of money you have in the bank, there are still only 24 hours in one day, 1,440 minutes, and 86,400 seconds. You, me, the baker, the butcher, the teacher, the girl at the gym, or the guy behind the Crypto project you’re most fascinated with. We are all provided by this great thing we call life, with the same amount of time in the day. It levels the playing field. Billionaires can’t buy more of it. Sure they may live a longer duration of time because they can afford the best healthcare and yeah they have more time for leisure because they outsource virtually everything but that’s not what I am talking about. I am talking about the present moment. It ticks along one second at a time for each of us, and if you really think about it, we’re all only ever living in the now, there’s no real past or future that you live in. Only now. And it is this time pressure that creates stress in our lives. We have all sorts of deadlines and usually, we’re juggling umpteen different things from kids, intimate partners, bills, projects around the house, work projects, screaming customers, and now you gotta pull yourself out of that, find the time to sit down and focus for an hour or two. I mean, right now at this very moment that I am writing this my eye keeps going back to the clock, I literally have 5 minutes left before I need to get out of my striped pajamas, put some clothes on and leave for my day job. This is the biggest challenge for most of us in the modern world, not just me. And in going forward I think that those things, be they technologies, habits, or the way we structure our lives, those things that can free up or help us manage our time better, those things will be very valuable in the very near future. I’d urge you, the reader, to think about what it is you are doing with your time. Or better put, what are you doing with your time tokens? If each minute of the day was one token, what did you spend it on? Are you using them to the best of your ability? Or are you squandering them away on social media, getting into arguments, wasting them watching TV, and playing video games? You only get one life to live. Don’t waste time. Don’t throw your time tokens away on rubbish. Spend it wisely. Remember you only get 24 whole tokens per day or 1440 tokenoshis. What is the next thing you hope to achieve in your career? The ultimate goal is to work on Crypto Fireside full-time and to expand and push content that helps people. I’m getting closer and closer each day. I can feel it, it’s right there within grasp. I see it. I feel it. It’s going to happen no matter what. Covid has solidified this even more for me. The fact that governments can decide which business is essential and which is not is absolutely terrifying. Melbourne in particular has been hit hard, not with Covid, but with Draconian measures. I’m not going to get into the arguments for or against it. It’s just the reality. During this crisis, I’ve seen friends and family lose their jobs, livelihoods, and businesses. Everyone is essential and every person’s livelihood is essential. If you are in a position where you can work for yourself and you can do it online, why the hell not!? I’m very lucky to be in that position. I’ve dedicated years of my life to my craft and now the opportunity is knocking and I’m opening the door. I think Crypto Fireside can inspire and motivate the next generation of innovators from the interview content alone and can become a resource for good. But like I say I am open to all possibilities, I’ve always had that entrepreneurial fire in my belly ever since I was a kid and the world is going through some very big changes right now, so who really knows what will happen next? I’m a storyteller at heart and there is a book or documentary in me somewhere in the future. It’s nothing I’m focused on right now but that would be one of the other ultimate goals of my career too. Wow, that’s admirable. Now, something more casual: What is your guilty pleasure of choice? A cigar, an alcoholic beverage, and sitting outside reading or watching some story about Skin-walker ranch or the Missing-411 topics. Do you have a non-tech-related hobby? If yes, what is it? I enjoy a good workout but gyms are closed here and have been for a long time. It sucks because I’m just not a home workout guy. Outside of that: life stuff in general. Hiking, bushwalking, fishing, barbecuing, a good book or movie, hanging out with friends and family, travel. Those kinds of things that everyone enjoys. What can the Hacker Noon community expect to read from you next? That’ll likely be the next Crypto Fireside interview, guide or review. Thanks for taking the time to join our “Meet the writer” series. It was a pleasure. Do you have any closing words? Meditate. Spend 20 tokenoshis doing this every day and your life will improve in leaps and bounds and the world will be a better place for it because you’ll be calmer, more relaxed, happy and content and you will spread that to people next to you like a tuning fork.

"Time is the Great Equaliser" Meet the Writer Andrei Rotariu AKA Crypto Fireside

In the , I introduced some of the high level concepts and reviewed some of the common things you can do. In this part we'll get down to the process. Again, it's important to stress that this is boiled down and concentrated. Debuggers Checklist Part I I don't want to discuss issue trackers, unit testing and proper TDD. I think there are many resources covering all of these. The focus of these posts is the debug process itself which often gets neglected as "tools". There's a lot of technique that separates the seasoned developer from a junior. Furthermore, there are many small advancements and changes we can't possibly keep up with. I'd like to cover all of those things (some in future posts). With that out of the way let's continue with... The Process Hopefully by this point you were able to reproduce your problem in the debugger. Possibly you even limited it to a small area you can step through. Now we need to actually track the issue and fix it. People think this is hard to quantify generically but it isn’t. It comes down to breaking the problem down into manageable pieces we can attack: Make the simplest assumption you can Validate assumptions While the bug isn’t found: Narrow assumptions Validate narrowed assumptions You’re probably saying: “Well dah...”. This is pretty obvious… It totally is. The problem is we don’t apply those properly and somehow skip a lot of the nuance in those steps. During this stage Rubber Ducking (talking to the duck) becomes useful. This is the process of talking to someone (or something) about your problem and assumptions. When we say things out loud or even try to verbalise them in our mind, it helps clarify our misguided assumptions.
I’ll try to get into more of these sorts of tricks in a future “tips and tricks” post. The Simplest Assumptions (image source: ) https://weheartit.com/entry/59844817 This is where most of us fail. We assume. I recently had a bug which I encountered by accident. I noticed the value of a variable in a stack trace. It was clearly corrupted. Since I was using a debug agent I incorrectly assumed that was the source of the problem. But I tried to verify again and again. When all else failed this led me down the road to a serious bug in the code. Obviously we can’t start by testing the assumption that . So we need to narrow it down to applicable assumptions. This “trick” isn’t the “end all” but it’s a very useful way to validate a lot of common assumptions. 1 + 1 = 2 Debug “Working Code” The best way to review your assumptions is to walk through working code. If your code fails for case X and succeeds for case Y, try case X first. See why the code works and step over the code block.Then try case Y. This should present you with two cases you can easily compare to help you narrow in on  the suspect. If this isn’t applicable or isn’t taking you anywhere you need to review the following: Exceptions State Threads/Synchronization Timings and Races I ordered these according to difficulty and probability. Exceptions Most of the problems are state, but exceptions are relatively easy to detect. So just place a breakpoint for all exceptions and verify that nothing “fishy” is happening behind the scenes in one of the methods you invoked etc. Slowly filter out the “valid” exceptions as you move through the process. Typically exceptions are “loud” and “obvious” so unless someone silently caught an exception (which happens), you should be in the clear. I would also strongly recommend a linter rule that checks against swallowed/unlogged exceptions. E.g. checkstyle supports check that blocks empty catch blocks. It still can’t block stupid code that does “nothing” in that block but at least it’s a start. this State While threads are a source of difficult bugs, most bugs are a result of bad application state. Try separating the state elements that are modified and the state that’s read by the block of code. Assuming you can, try overriding it within your breakpoint by setting a value of a variable during debugging. This is a great capability that most developers don’t utilize often enough.  If you’re able to narrow down the value of a specific variable as the cause of the problem you’re already well on your way to solving the problem. If this isn’t helping, try identifying specific fields that might be problematic. Most debuggers will let you place a breakpoint on the field in order to watch modifications to said field… I used that feature a couple of times while consulting and people were always surprised you can do that... In IntelliJ the icon looks different for a field breakpoint. But it’s a breakpoint like any other, you can apply a condition to it and see the stack etc. Now if the problem persists and everything is failing… Try changing the code to return a hardcoded state or a state from a working case. I’m normally not a fan of techniques that require code change for debugging since I consider the two distinct tasks. However, if you’re out of all options this might be your only recourse. Naturally you should use “Reload Changed Classes” (or Apply Code Changes, Edit and Continue etc.) if applicable. Notice that there are also lower level memory breakpoints that are useful to debug memory access. We’ll discuss these when we cover debugging native code which I plan to cover in the future. Threads/Synchronization Thread problems are hard to solve… That’s not really something we’ll get into. We’ll only focus on finding and understanding the bug, and that’s an easier (manageable) task. The easiest way to check threading issues is as I mentioned before logging your current thread and/or stack. Do that in the block of code that’s causing an issue. Then add a similar log breakpoint on fields used by the block of code. Thread violations should be pretty clear in the logs. You can also get a thread dump during a breakpoint, that’s a feature of pretty much any debugger out there. E.g. in IntelliJ/IDEA you can select . This isn’t as useful as going through the stack frames but it’s a start. Run -> Debugging Actions -> Get Thread Dump Specifically in IntelliJ/IDEA I recommend right clicking the debug tab and enabling the thread view. Then enabling thread groups by right clicking within the tab and selecting like this: Customize Thread View It provides a much “cleaner” view of the threads as a hierarchy instead of the default look in IntelliJ which is better geared towards single thread debugging. Deadlocks and Livelocks Deadlocks are usually pretty clear. The app gets stuck, you press pause and the debugger shows you which thread is stuck waiting for which monitor. You can then review the other threads and see who's holding the monitor. Fixing this might be tricky, but the debugger literally “tells us” what’s going on. With a livelock we hold one monitor and need another. Another thread is holding the other monitor and needs the one we’re holding. So on the surface it seems that both are working and aren’t stuck. A bit like two people running against each other in the hallway and trying to step out of each other's way. Unfortunately, livelocks can happen without threads being physically “stuck” so the code might appear fine on the surface without a clear monitor in the stack traces. Debugging this requires stepping over the threads one at a time in the thread view and reviewing each one to see if it’s waiting for a potentially contested resource. It isn’t hard technically but it’s very tedious. That’s why I recommended enabling thread groups in the thread view above. A typical application has MANY threads (and more coming with project ). This produces a lot of noise which we can reduce by grouping the threads and focusing on the important parts. Loom Performance and Resource Starvation Performance problems caused by monitor contention are a bit harder to track with a debugger. I normally recommend randomly pausing the code and reviewing the running threads in your application. Is thread X constantly holding the monitor? Maybe there’s a problem there. You can then derive assumptions and prove them by logging the entry/exit point for a lock/synchronized block. Notice you can use a profiler and it sometimes helps, but it might lead you on the wrong path in some cases. I plan to discuss profilers in a future post. Resource starvation is an offshoot of performance issues. Often you would see it as an extreme  performance issue, that usually only happens when you try to scale. In this case a resource needed by a thread is always busy and we just can’t get to it. E.g. We have too many threads and too few database connections. Or too few threads and too many incoming web requests. This problem often doesn’t need a debugger at all. Your environment usually indicates immediately that it ran out of the given resource so the problem is almost always plain and obvious. The solution isn’t always as clear, e.g. you don’t want to add too many threads or DB connections to workaround the short term problem. You need to understand why the starvation occurred… This happens because of two different reasons: Not releasing resources fast enough Not releasing resources in all cases The first case is trivial. You can benchmark and see if something is holding you back.
The second is the more common: a resource leak. In a GC environment this is often masked by the GC that nicely cleans up after us. But in a high throughput environment the GC might be too slow for our needs. E.g. A common mistake developers make is opening a file stream which they never close. The GC will do that for us, but it will take longer to do that and the file lock might remain in place, blocking further progress. This is where encapsulation comes in handy. All your resource usage (allocation/release) must be encapsulated. If you do that properly adding logging for allocation and freeing should expose such problems very quickly. This is a bit harder to detect with DI frameworks like Spring where connections etc. are injected for you. You can still use tricks like this, to . track even injected data Timings and Races This is one of those elusive bugs such as race conditions which are often classified as thread problems (which they are) but during a debugging session it’s often easier to see them as a separate task. These often occur when your code has some unintentional reliance on performance or timing. E.g. Many years ago I had an app that crashed only when our customer was using it. The app was a mobile app and our customer was a local operator. It turned out that we had a bug where the networking in the customer site was SO FAST it just returned the response immediately and everything else wasn’t ready. So the application crashed. Usually the problem is slow performance and timeouts. So this was a case where my assumption that the network was slower than the CPU was flawed... The way I approach race conditions in threading code is this: “It’s a state bug”. It’s always a state bug. When we have a race condition it means we either read from the state when it wasn’t ready or wrote to the state too late/early. Field breakpoints are your friends in this case and can really help you get the full picture of what’s going on.  You can also simulate the bad state situation by changing variable values. Finally If you follow through your assumptions and catalog the bugs into one of those common pitfalls then you’re 90% of the way to understanding the root cause. The rest is deciding on the right fix for the problem. I won’t go into fixing the bug, filing the issue, building a test case etc. You should do all of that but there’s plenty written about that. In fact in preparation for this blog I picked up a lot of debugging books on Amazon. Turns out most aren’t debugging books. Yes they cover it in one or two chapters. The rest of the book is always about the process, test cases, and everything surrounding it. I think that would be fair if debugging wasn’t a huge subject that can fill up a book. In my opinion, it sure can and I’m just getting started. "really" Tune in for more!

The Debugger Checklist [Part 2]

Growing up in a rural town of 700 people, the odds of me talking with a member of parliament were slim at best—let alone talking with them about monetary systems, policy, remittances, GDP growth, etc. But there's one conduit that led to my discussion with Lord Fusitu'a and it's #Bitcoin. And through that discussion, I learned exactly why he drafted a proactive bill aiming to help the citizens of Tonga better their lives through Bitcoin adoption. A Look at the Kingdom of Tonga Tonga is an island nation comprising more than 170 islands in the South Pacific. Spread over an area the same size as Japan, Tonga lays just east of Fiji, south of Samoa, and is 2,000 km northeast of New Zealand. Tonga is one of two Kingdoms in the world to never have been colonized so ancient noble bloodlines still exist today. A testament to its people, Tonga is commonly referred to as "the friendly islands." The Tonga political structure was modeled after the UK system that has a House of Lords and a House of Commons, except Tonga practices a unicameral parliament that combines government in a single house. Meet Lord Fusitu'a Lord Fusitu'a is a Tongan Noble, politician by career, and barrister and attorney by vocation. By his own description, he has, "always been a bit of an IT/computer nerd." Knowing this, a relative of his in the US called him in 2013 to tell him about a new technology called Bitcoin. A few years later, Lord Fusitu'a invested money with a businessman claiming to buy Bitcoin on his behalf, only to have the man disappear without a trace. In 2019, when Lord Fusitu'a had to be airlifted for a lifesaving surgery in New Zealand, he found time to immerse himself into Bitcoin and blockchain during his recovery. He was amazed at the technology. "Once I understood the technology, it became apparent that as a store of value, it's the most pristine, hardest money and asset that mankind has ever created for the developed world. But for the developing world, it can be life changing right now." Since then, Lord Fusitu'a has become a diehard Bitcoiner, and aims to use the technology to help Tonga as a developing nation. He was kind enough to do a Q&A with me about Bitcoin and how it can improve the lives of many people in Tonga, and even enhance the global monetary system. Have the locals started downloading Strike or other wallets and looking into BTC for remittances? Q: No downloading Strike yet, as it's not currently available outside the US. But its implementation is what will free us of remittances. We are using Muun Wallet, Blue Wallet and Wallet of Satoshi for now as well as sending remittances on layer 1 to Warm Wallets. A: Do you have a group of people in Tonga driving BTC adoption, like Bitcoin Beach did in El Salvador? Q: I do have a team of people going out to villages to discuss anticorruption and financial literacy as a foundation for understanding Bitcoin, and then Bitcoin proper. A: Let's say the Bitcoin bill, as you have amended it, passes. How will life change in Tonga? Q: Effects of proposed bill: A: 1. Adding 30% of every remittance, and thus disposable income, back into the pockets of every remittance receiver (most of the population) by using Strike or other lightning wallets. This is a commercial solution using an app on everyone's phone since an app at the point of sale doesn't require an Act of Parliament. Because our GDP is 40.1% remittance dependent, it's adding 30% to that 40.1% of the GDP to the tune of over $60m. 2. In our country, the government charges a 15% Goods and Services Tax on everything. So, if everyone has 30% more disposable income, they're paying 30% more into that 15% the government collects, and therefore increasing the amount of taxation revenue. 3. Of course, increasing disposable income by 30% does not mean everyone will spend it. Some will spend a part and save a part; remembering they got by on 70% in the past, they will keep living on 70% and save say 15% and invest 15%. Even if they lose the 15% investment, this is money they never previously had so they are not worse off. Some will save the whole 30%. If they save it in Bitcoin rather than Fiat, they are laying the foundation for future financial freedom and generational wealth by saving when they have never afforded to have savings before. In addition, saving in an asset that appreciates on a CAGR year-on-year average of 200% per annum, increases their net worth when they'd previously been hand-to-mouth for generations. Below is a graph comparing saving in BTC vs the S&P* Could you share why Bitcoin's monetary system will beat the traditional monetary system? Or tell us why you favor it? Q: Bitcoin will beat the traditional money system by: A: 1. Converting the 40% who are unbanked in our country to bank users. Tonga lost its national bank a while ago. We now only have expatriate predatory commercial banks who tend not to give capital to the large part of our population who are artisanal farmers, fishermen, fine mat hand crafters and tapa cloth producers. Bitcoin will give these people a way to have a central bank in their pocket and get paid directly from the export markets to which they sell, peer-to-peer cross borders, in a nano second, effectively for free. 2. As with everywhere else in emerging markets, we have been negatively affected by the influence of the IMF and the World Bank. What they do is provide loans to developing nations but they attach conditions to these loans which most often are austerity measures to cut public spending. Thus, we cut wages to civil servants, which in 2006 caused the only riots in our country's history by disgruntled government workers who were upset about their wages being cut. So it causes social upheaval. Also, since they force you to suppress public spending, you don't get to develop secondary and tertiary industries, which forces, for example, Africa to remain a mine and South America, Asia, the Caribbean and the Pacific to be plantations that service the developed world. This way, developed countries receive cheap raw goods to consume and then process into manufactured goods that they sell back to us at a profit, thus trapping us into a perpetual trade deficit. All while the loans trap us into a perpetual debt cycle. Further, our economists get trained in traditional Keynesian economics at first world universities, only to come home and take up positions as central bankers fostering relationships with their academic mentors who either transition to the IMF or World Bank or have influence there. Thus, our own economists as central bankers work in cahoots, either naively or deliberately, to help first world central banks exert their hegemony over us. Bitcoin fixes this. We get to transact and save outside this generational cycle of oppression and lay the foundations for financial freedom and possible generational wealth. Choosing Bitcoin as a monetary system for us is not an attractive alternative—it is our only choice for survival. Is there anything the Bitcoin community can do to help expedite adoption in Tonga and help residents change their lives? Q: A: 1. Lobby your politicians to be pro-Bitcoin. More adoption in the first world gives more validation and credibility to the large number of emerging market nations who will adopt it earlier than the G7 by necessity, like El Salvador. 2. Keep on operators like Strike to encourage them to support adoption as the commercial solution in Tonga. 3. The Bitcoin community has been awesome for this, but just as a reminder, keep advocating for adoption in Tonga on social media. Many on Bitcoin Twitter have our flag in their names and tweet about Tonga, such as Bitcoin Citadel. This is great and this support will help propel adoption. 4. Of course, you can send people sats to help them get off zero and begin their Bitcoin journeys. Proactive Measures Lord Fusitu'a aims to add Tonga to the list of developing nations using Bitcoin in some form or function to help their citizens. El Salvador recently made Bitcoin legal tender and added Bitcoin to its reserves. Other countries look to follow suit: Ukraine and Cuba just passed bills legalizing Bitcoin and digital assets, while Paraguay and Panama are redrafting bills to promote the adoption of Bitcoin. It can be eye opening for westerners to put themselves in the shoes of the citizens of developing nations. Bitcoin can remove 99% of remittance fees. Plus it has money transferred directly to the recipient, saving time and energy. This also eliminates a third-party with a central point of failure, keeping the money in the pockets of those who need it most.

Q&A on BTC with Tongan Noble: Member of Parliament Lord Fusitu'a

With a group of friends and crypto archeologists, digging into the early history of Ethereum NFTs we discovered the EverDragons, minted in June 2018. The EverDragons are the first example of cross-chain NFTs (Ethereum, POA, Tron) and among the first to introduce games with NFTs. They are an incredible piece of history and technology and we're about to make them even better! In the rest of this article I'm going to describe why we think the EverDragons have such historical importance and what we're doing, in collaboration with the original team, to restore and continue the project. A Brief History of NFTs If you're reading this article you probably know more about the than me, and I definitely don't want to start a war around who's been the first to do what, but I think it's important to discuss a few temporal references to contextualize the EverDragons. history of NFTs The first example of NFTs on Ethereum were the CryptoPunks, back in 2017. Technically speaking they weren't ERC721 because the standard didn't exist yet, but they behaved like NFTs. Later that year, the CryptoKitties were born, and are widely accepted as the first ERC721 NFTs. What came next? Nobody agrees. Articles about the history of NFTs are blurry. They mention the 2019 crypto winter, glow about the incredible ecosystem we have today, and conclude with the most expensive NFT sold at the time of writing. So… nothing in 2018!? Suddenly we had a standard for NFTs but no innovation that year!? Mmm... But before we talk about 2018, let's mention what's happening on the different blockchains. There are multiple kinds of NFTs, not just from an artistic perspective, but from a technical one. The most popular NFTs are on Ethereum (ERC721 or sometimes ERC1155). However, the drawback of Ethereum today is the high transaction fees. It's not uncommon to pay more than $200 in fees alone to buy an NFT on Ethereum! As other blockchains develop, so do NFTs and marketplaces on these chains with lower gas fees, for example popular choices today are Polygon, Tezos, and Solana (and probably more, apologies if I didn't mention your favorite one.) It's also worth noting that any given NFT collection is typically minted and exchanged on a single blockchain. But in parallel to NFTs, the blockchain technology is evolving with more and more cross-chain applications, that is to say applications that spawn across different blockchains. That means that in the near future, we'll likely see a flourishing of cross-chain NFTs, or NFTs that you can transition from one chain to another. For example, you could buy an NFT on Ethereum or Polygon and then move it  or “bridge it” to Solana to play a game. Now that we’ve covered early 2017 NFT projects, NFTs on different blockchains, and cross-chain NFTs, it's time to talk about 2018 and the EverDragons. The Original EverDragons As we mentioned at the very beginning, the EverDragons were the first example of cross-chain NFTs, the first NFTs on the Tron blockchain, , and among the first to introduce games with NFTs. As if all of that is not cool enough, they're dragons! minted in December 2018 They’re a form of generative art and were minted uniformly at random. They were never issued with the intent of being collectibles, but as tokens to participate in games and to explore the capabilities of different blockchains. For example, dragons could join a "race" (on Ethereum) by betting on the price of different cryptocurrencies (e.g., BTC vs ETH vs...); after one hour a coinmarket cap oracle would check the difference in price of every coin, and the winning dragon would collect a price. This is an early example of a prediction market you could play by owning a NFT, back in 2018! And there's more. As Ethereum is relatively slow and can get rather expensive, it's not suited for faster on-chain applications. This is where cross-chain NFTs come in. An EverDragon could be moved to a different chain to participate in different games. For example you could move your dragon to the Tron chain and play four in a row, in real time. Or Goldmine, the game that in the first week of January 2019 had than all the other games on Tron combined. more transactions In summary, the EverDragons were a one of a kind NFT, not focused on being collectibles but designed to explore blockchain capabilities through games. Unfortunately, the 2019 crypto winter phased out the project and the team moved on to different things. Discovery and Restoration Discovering the EverDragons has been one surprise after another. We knew they were nearly mystical NFTs that could move across chains, but that was about it. On OpenSea the dragons no longer even had an image, the bridge for moving them cross-chain was down, and the community practically dead. We reached out to the original team to see if they had any interest in reviving the project. In the weeks that followed we learned more about the original design, the games briefly described above, the structure of the dragons' DNA, and the generative art process. We really started to appreciate the quality and hard work that went into making the original EverDragons! At this point, one thing became clear: the EverDragons had to be restored. We agreed to collaborate and began brainstorming ideas and weight in our time commitment and costs. Most importantly, we wanted to find a solution that would preserve the integrity of the original project. Our first action as a newly formed team has been to work with the original team to restore the images of the dragons, so you can now appreciate them all on . Each dragon has 7 layers (body, eyes, head, horns, tail, legs, and wings), an element (fire, air, water, and earth) and a color. There are 24 variations for each layer, leading to over 4.5B different combinations, and 10 color palettes for each element, that give the dragons an incredibly polished final touch. OpenSea And since they are randomly minted, there are only 1332 unique EverDragons in circulation (across Ethereum, POA, and Tron). By analyzing the DNA, we can see what we'd expect from a uniformly random generation: each type of head, body, eyes, etc. appears more or less in 1/24 of the dragons, so in about 70 of them. There's no real element of rarity, even though if you look at the images, certain elements  like gold chains or ornaments on the horns stand out. In recent years, the explosion of NFTs has shown us how people think about collectibles on the blockchain, what they want to see and own, the most appreciated rarity attributes, etc. All the basic ingredients that make for a great collectible were part of the EverDragons since the beginning. They simply weren't promoted as such. This is what convinced us to launch a new set of EverDragons that we call -with great imagination- EverDragons2, that are designed to be collectible. We think this is a unique opportunity to help the community rediscover an early piece of blockchain history, and to finance the operations and restore and further the original project of a truly cross-chain NFT. To the best of our knowledge, this is the first time a new team has aimed to revive a dormant NFT project. We're working very closely with the original team and taking precautions to preserve the integrity of the original project. In a future article I’ll describe the EverDragons2 in detail... stay tuned!

Rediscovering the EverDragons, the First Cross-Chain NFTs

Hi Paruyr, welcome to our series “Behind the Startup.” Please tell us about yourself and the story behind Azuro? Ishan Pandey: Hi Ishan! Thank you for reaching out. I was a professional sports arbitrage player for 10 years before I started Bookmaker Ratings, the biggest online media about sports betting in Eastern Europe. With six million unique monthly users, we are the most prominent lead generator for the sports betting industry in the region. We also act as an intermediary between players and betting operators whenever those two have a dispute. We have returned more than 11 mln USD to players through mediation. Paruyr Shahbazyan: So, even though betting has been around for more than 2000 years, being one of humanity’s first forms of contract, it is broken. The betting industry lacks fairness and transparency. The reason is that the system is built on negative incentives which put bookmakers and players against each other. Players and betting operators do not trust each other. This problem has created a niche for my own business - Bookmaker Ratings. If players and sportsbooks trusted each other, the company wouldn’t exist. Needless to say that smart contracts are solving the issue of trust, thus disrupting not only the betting industry but the ratings/review industry as well, in which Bookmaker Ratings itself is. Understanding the problems of the industry and the threat to our own business, we decided to lead the disruption and create a decentralized protocol for betting. Users can bet in a trustless way. No one can influence how the platform’s smart contracts will resolve. Plus, we are democratizing the business of betting as a whole. It is well known that the betting industry is very capital and know-how intensive with high barriers to entry. We are breaking down the role of a betting operator into several smaller roles, making it available to anyone who wants to benefit from liquidity and data provision, front-end development and operation, and decentralized governance. Please tell us about how blockchain technology and NFTs can disrupt the betting industry? Ishan Pandey: One of the main problems in the current betting industry is that nearly 100% of the control is in the betting operator’s hands. This brings us to a situation where operators ban smart players, lower payouts for winning bets, do artificial KYC checks to freeze the funds on players’ accounts, and much more. Paruyr Shahbazyan: Therefore, it is critical to use smart contracts technology to build a decentralized betting protocol. Thus, it brings full transparency and fairness to the betting process. Other solutions utilize smart contracts, but we differentiate from those by providing service and user experience that matches the traditional betting operators. By that, I mean fixed odds with competitive prices, various betting markets and outcomes, and high liquidity - all traits that current blockchain solutions do not have. This is truly unique. In regards to NFT’s, each bet on the platform is an NFT. It has two functions. Until the moment of settlement of the bet, it is a financial NFT. It can be traded on our marketplace. Let’s say you have placed a bet, and for whatever reason, you decide that you do not want it to play out (you want to cash out before the event is played). You can sell it on our marketplace. Furthermore, the buyer gets your bet with a bit of a discount, thus getting an edge in terms of the price vs. probability of the outcome. After the bet is settled, it stops having value as a financial NFT, but it can still have value! By being an internet media, we know very well which kind of stories bettors are interested in. The most popular formats are either some crazy winnings or some very upsetting losses. Both types of stories are actively shared and discussed in bettor’s communities. And our NFTs are 100% proof of those stories. I often refer to Maradona’s “hand of God” moment to describe the historical value of an NFT bet. Imagine someone had lost or won a large amount because of that crazy goal. I think such an NFT would have had massive value as a collectible. Besides that, users can be rewarded with NFTs for a variety of achievements while placing bets on the platform (e.g., the longest winning line, awkward losses, highest odds won, and so on - the possibilities are virtually infinite). To summarize, NFT technology allows for true innovation that will enrich the betting experience dramatically in a positive way. We create the opportunity for secondary markets (bet cash-out or purchase with a discount, markets for memorable bets as collectibles) and lots of engaging gamification that turn the usual betting experience into something more engaging and exciting. The rise in popularity of non-fungible tokens, or NFTs, has had a significant impact on the betting industry, allowing for secondary markets and engaging gamification. In your opinion, what has led to this shift in the industry from the traditional ecosystem towards a more DeFi approach? Ishan Pandey: I am not aware of any betting protocols or platforms that have begun using NFTs as a feature for betting. Yes, online gaming projects work closely with NFTs to add more gamification into the process. However, our market analysis shows, the idea of implementing NFTs into betting is unique so far. Paruyr Shahbazyan: The blockchain technology’s foundations offer a lot of potential for adding a sense of confidence to online gambling. In what ways can an online betting platform that employs this technology ensure transactional transparency? Ishan Pandey: Well, all transactions are visible on the blockchain. You can simply look in the transaction explorer and find what you are looking for. Paruyr Shahbazyan: This brings us to another critical issue present in the industry. People who work in betting are familiar with a term called “affiliate shaving.” It means that betting operators stop paying commissions for part of the players they have received from an affiliate. Often they would just say: Furthermore, there is nothing affiliates can do - the data is a black box, under the operator’s control. This is another example of how there is zero control in affiliates’ hands and 100% control in the operator’s hands. Essentially - it all comes down to operators’ decency, which is quite naive if you speak to the experienced people in the industry. “this account has stopped betting.” Blockchain is solving this issue. A crypto address represents the bettor. Moreover, you can easily see whether a given address is interacting with the platform’s smart contracts or not. Plus, the affiliate commission is set in the smart contract and cannot be changed. This means that the affiliate will get a guaranteed lifetime commission for all of the bettors’ activities that he provides to the platform. No more “affiliate shaving”! Individual pieces of crypto known as non-fungible tokens (NFTs) are at least partly to blame for the massive volumes of climate-warming carbon pollution released by the cryptocurrencies used to buy and exchange them. What are your thoughts on the negative influence of NFTs on the environment? Ishan Pandey: With regards to NFTs, I think it is not fair to blame NFTs, but rather the environmental impact of the chains they are on because NFTs can be deployed in many ways. To be honest, I always tell all my friends that bitcoin is a useless thing. Thus, I have recently sold all my BTC holdings and bought Ethereum and BNB.  In addition, as everyone knows, Ethereum goes from PoW to PoS as a protocol and will no longer negatively affect the environment. Also, we are planning to launch the platform on the Ethereum blockchain, and in this regard, our conscience is clear. Paruyr Shahbazyan: However,  the fact that so much energy is spent on PoW is awful, especially because bitcoin does not carry any value itself.  It was conceived as money, but it did not and never will become such because of its volatility. Then, looking at Bitcoin as digital gold because it has a limited emission makes some sense. Perhaps this is logical, but I’m not a supporter of keeping gold either. Gold does not pay dividends, and it just lies there in your portfolio with almost zero profit. These assets are usually used to escape/hedge during crises, but gold has a practical use, too, as a metal. Bitcoin, unfortunately, does not even have that. It’s only used for speculation. Institutional purchases support the price of bitcoin. However, these institutions do not buy bitcoin because they think it is a useful thing. They buy it because of their own stakeholders’ pressure and to ride the wave of speculation. So Bitcoin is the pioneer who, however, should die naturally. That does not mean I am not happy when bitcoin grows - of course. I am because everything else grows with it, but at a certain point, the rest of the industry will be able to grow on its own, and this process is already starting. Ishan Pandey:  In your opinion, will a decentralized infrastructure promote and uphold better transparency, efficiency, responsibility, and fairness while also sharing more value with more betting participants? Paruyr Shahbazyan:
 Absolutely, the usage of blockchain as a base infrastructure for betting will add more value and fairness to the betting industry. We can see how other traditional industries like finance, data storage, content generation, etc. got promoted and improved through blockchain decentralization. In the case of betting, the traditional betting market we have right now (including the billions of bettors) might need some time to adapt and migrate onto the blockchain. As this happens, though - the full power of decentralization will completely disrupt the betting industry and provide transparent and efficient betting to everyone. Initially, the biggest portion of users will be a mix of traditional bettors who are more tech-savvy and have tried or are open to trying blockchain applications and crypto native users who are enjoying new ways to benefit from blockchain betting like farming, liquidity provision, and staking, as will be possible when the Platforms Protocol’s main net is live. DeFi is rapidly growing in scale as more inventive apps continue to push the boundaries of how customers can get utility from their digital assets. However, there are a few roadblocks in the way, such as volatility, that have been holding down DeFi. What can be done to address these issues? Ishan Pandey: We already see how much more attractive DeFi for stablecoins is, with options for yield that are dozens of times better than what is possible in traditional banking. As of today, banks do not give you any interest for a deposit in dollars and euros, and some even take negative interest to keep your money. Paruyr Shahbazyan: In DeFi, you can put USDT in liquidity pools and earn 10 percent or often - much more. As for volatility, yes, it is an issue. For example, if you bought crypto and earn some yield in it, there is a risk that the coin will depreciate, but there is also the option to provide liquidity in stablecoins. In that regard, liquidity pool farming is susceptible to volatility, but the impact is somewhat mitigated because of the adjustment of the pools in terms of the weight of the stablecoin and the weight of the other cryptocurrency in the pool. Innovation in that regard is fast, and I am sure there will be safer and easier products to use, which will be a massive boost to the sector. Elon Musk has repeatedly promoted memes and has even endorsed meme cryptocurrency Dogecoin in several ways. How do you think the ‘meme culture’ will assist cryptocurrencies, particularly in terms of engaging today’s youth? Ishan Pandey: I do not see any benefit in Dogecoin, except for speculation. But, what makes Elon Musk, in general, very positive and helpful for the crypto industry is that he introduces the general public to the industry. This is a good way to communicate new information, in general. Because, if he was to write some boring posts with e.g., financial data, or any technically heavy details, the audience of these posts would be ten times lower. So, what he does for the industry as a whole is very cool. He acts as a great driver of cultural interest, which is very positive on one side, as I mentioned, but can cost many people money if they get burnt by Dogecoin or Bitcoin speculation. Paruyr Shahbazyan: In the end, though, I believe such tectonic changes in development and disruption always come with some sacrifices. Some people will make bad choices, some people will make good choices, but net-net - more people will educate themselves about crypto markets and trends. Moreover, we can thank meme culture for that. Ethereum recently broke the $4,000 barrier, marking a new high in a stunning surge that has outpaced bitcoin. Do you believe Ethereum will become more important in a future decentralized banking system? Ishan Pandey: One hundred percent, I think that Ethereum will be the main cryptocurrency and the core blockchain infrastructure because it has a lot of momentum and it doesn’t stand still. They are evolving, and there is a leader, Vitalik Buterin, who reacts to the challenges of change, and I think that Ether will dominate and will be more valuable than Bitcoin, for sure. I recently sold all my BTC holdings for Ethereum, and it’s going pretty well for me so far. Paruyr Shahbazyan: : Officials in China recently said that they will adopt stricter cryptocurrency rules, prompting bitcoin prices to drop. What effect will Chinese legislation have on the global economy? Ishan Pandey China wants to promote its digital yuan, so they introduce new regulations. They see the pressure on other digital assets as a good thing helping them make the yuan more popular. At the end of the day, they are hoping to challenge the dollar as a reserve currency on crypto/digital rails. I understand this attempt. However, I cannot predict if it will be successful or not. Paruyr Shahbazyan: What new patterns will we see in the cryptocurrency market, particularly in the post-Covid-19 era? Ishan Pandey: Savvy people quickly realized that keeping your savings in stablecoins in DeFi, which will still grow. Paruyr Shahbazyan: Though people need to acknowledge that stablecoins can be centralized, I have a Tether account, and it got frozen with a 100K in it for more than a month. Then I said, okay, please send the money back to the crypto wallet that it came from. Moreover, when I asked when can I get my money back, they just said, “be patient” ... This reminded me that if one depends on people making decisions, it can get ugly at any moment. Also, it can get surprisingly stupid… After waiting for a month to get my money back, I received an email that they had transferred 72K more than they should! After all that is waiting, I was tempted not to send it back, but I assumed that the person who made the error was different from the one who had frozen my account, so I sent the 72k back. Getting back to the subject of patterns, it also seems to me that cross-border payments, e.g., for salaries and so on, are a bigger and bigger thing in crypto. In the digital realm, a lot of companies will be paying freelancers or employees who work in other countries with stablecoins.

"I Always Tell All My Friends that bitcoin is a Useless Thing"

This is Hacker Noon’s Interview Series! See all other Interviews . Good-Company here HackerNoon Reporter: Please tell us briefly about your  background. Hi Hackernoon! I am Tadeas, and I work as a Growth Marketer over at UXtweak. As younger, I was playing around with WordPress and HTML. After my dreams of making a ton of money running ads on my sites were crushed by the cruel reality (I was a teen, don't judge me :). I realized how important digital marking is, so I started to take an interest in it. Now I am happy to say I am putting both of my interests to good use at my work. What's your company called? And in a sentence or two, what does it do? We are - a user experience (UX) research platform providing tools for usability testing, information architecture research, behavior analytics, and conversion rate optimization for websites, web apps, and prototypes. UXtweak Simply said - intuitive and user-centered ( ). we provide everything you need to make your websites better What is the origin story? UXtweak started as an idea of when he realized that there needs to be a better and more accessible way to test your websites than an expensive testing session in UX laboratory. He set out to bring the experience of high-level UX research into the online world, making it more affordable, faster, and simpler. Eduard Kuric (UX researcher, developer, and then Lead of UX laboratory) He put together a team of developers and UX researchers and started working on it. He quickly realized that even though he had awesome developers and researchers, he needed someone to take care of marketing. Now, comes into the picture. After Eduard presented the idea to him, he not only agreed to take care of marketing but bought a share of the company, and he became our enthusiastic CEO. Lubomir Lajos (CEO of a marketing agency, ex developer, and once Eduard's college) What do you love about your team? They are not afraid of difficult challenges, we are a self-funded startup in a competitive market, and our competitors have millions in funding, but that doesn’t stop us. They are innovators and top of their fields but are still down-to-earth people you can have a lot of fun with on teambuilding. If you weren’t working at your company, what would you be doing? I would be working in a marketing team in a different tech startup. At the moment, how do you measure success? What are your core metrics? Most of our efforts go towards improving our platform. We often release new tools and functionalities for our customers to use. So we care a lot about the satisfaction of our users, which I think should be one of the most important metrics for companies to take note of. Business-wise the most important metrics for us are recurring revenue and conversion rates of our website. We also cannot forget about the traffic on the website, brand mentions, or positions on the Google search result page. What’s most exciting about your company traction to date? For me, it is the fact that our team has already created a product that can cover all the stages of the development cycle - from prototypes to finished products. With UXtweak, you won't spend time and money building a product that users cannot use. What technologies are you currently most excited about and most worried about? And why? I am very intrigued by artificial intelligence. On the one hand, I am very excited about it as I believe it has the potential to be one of the greatest inventions of mankind.

Tadeas Adamjak from UXtweak Talks About How to "Make Your Websites Better"

Introduction Web services are purpose-built, custom web servers that support the needs of specific applications. Interaction with web-services is facilitated by Application Programming Interfaces (APIs) which are used by the client-side application. A web API is the gateway to any given web service – it listens to incoming client requests and sends the outgoing response to the client. Developers should aim to design web APIs that are easy to maintain, easy to extend, intuitive, and platform independent. The following article suggests some principles to keep in mind when designing RESTful APIs. REST Method Guidelines Use GET to retrieve representation of the resource identified by the request URL. GET requests can be repeatedly executed and should not cause any side effects (e.g. no state changes allowed) on the resource identified by the URL. Use PUT to add a new resource identified by the request URL. The request body must include a representation of a resource that needs to be stored. Use PUT to update or replace an existing resource. If the resource already exists, PUT overwrites the resource state with the representation supplied in the request body. Use POST to request creation of a new resource under a collection in request URL path. The POST response body is HTTP status 204 (empty) or HTTP status 201 (a representation of the resource created). Use DELETE to completely remove the resource identified by that URL. After a successful DELETE request, the resource is no longer available. Subsequent GET requests on the resource must return HTTP status 404. To partially update the state of an existing resource using a URL, use PATCH request and provide the requested updates in the request body. The PATCH response returns a representation of the resource identified by the URL once the requested changes are applied. URL Path Guidelines Forward slash separator (/) is used to represent hierarchical relationship. Use Hyphen (-) to improve readability URLs are case-sensitive except for scheme and host components; prefer lowercase in the path. Use a plural noun for collection names; it should reflect what the collection contains Do not use CRUD function names in URLs e.g. DELETE /deleteUser/1234 is an anti-pattern. The URL path segments are alphanumeric and follow camelCase convention. The URL path segments are intuitive, unambiguous, and succinct. Resource Representations Guidelines Encode the resource representation as application/json except where standard media-type representations are available. A collection within the resource representation is encoded as application/json with an array attribute (elements represent resources of the collection). Date and time fields must be represented as strings and conform to format. RFC-3339 If the service supports pagination for GET requests, the request must also accept limit parameter (maximum number of resources to return) and offset parameter (index in the result set). Resource identifier field called “url” must be present in a server response which points to the absolute and canonical URL of the resource itself. If another REST service is the source of truth for some data, that given data cannot be included in the resource representation (i.e. a given REST service cannot act as a proxy for another RESTful resource). When returning an HTTP error code, it should conform to . RFC-2616 Security Guidelines Use authentication and authorization (e.g. ) to protect resources. OAuth Open Authentication If a REST request contains sensitive and personally identifiable information (PII), it must be authenticated. Authorization scopes required for access must be clearly defined for a REST request. Do not allow content (when not intended) or PII leaks between users and server components. Use HTTPS (secure channel) for authenticated REST requests. A REST request cannot contain authentication, authorization, or PII in the URL. Conclusion Uniform programming language agnostic REST APIs that converge on a common set of guidelines will benefit the developers. They can focus on writing the server code that powers the web services rather than debating on whether to use HTTP POST or HTTP PUT or worrying about the intricacies of RESTful API design.

When programmers choose React Native as a platform for developing mobile apps, they search for benefits such as a single codebase for multiple systems, faster development, and TypeScript support. However, where is the most crucial aspect of application security? There are a lot of misconceptions about React Native app security floating around the internet. App structure of React native: For cross-platform programming, React Native offers an option. On iOS, the app uses native JavaScriptCore, whereas, on Android, JavaScriptCore libs are included in an APK. A bridge is present to allow communication between the JavaScript engine and the application’s native components. When events occur in the native component of the program, they are converted into messages, processed, and then delivered to the JavaScript engine. Ways to Secure Your React Native Application: If your app has an identification function where users log in to establish an account, make sure it’s safe since client-side access controls are vulnerable to a variety of security risks that might compromise the app’s protocols. Securing HTTP authentication: Most notably, React Native Mobile App Development uses one of the following authentication methods: JSON Web Token, OAuth, AuthO, React Router, and PassportJs. This security flaw often occurs when an application isn’t secure or has restrictions in disguising IP addresses. As a result, interacting with the server becomes harder, causing problems for services to function. Securing against DDOS: Here Are Some Options for Putting a Halt to it: API rate limiting: Simply restrict the number of requests from a certain source to a specified IP. If you’re using Axios, there’s a full library called Axios-rate-limit. Add API limitations at the app level. Make server-side calls rather than client-side ones. Tests should be integrated to protect the application level. : Use the following code to see if an iOS device is jailbroken. Create a React Native Native Module and integrate iOS code into your iOS project. Jailbroken device detection We’ll Look for the Following to See if There Are Any Jailbroken Devices Make sure Cydia is loaded. Check to see if the program can change system files. Check for unknown files. Check for additional dubious programs (FakeCarrier, Icy, and so on) that have been installed. The Rootbeer library is useful for detecting rooted devices. Simply follow the installation instructions, and you may use the React Native Native Module to access Rootbear’s capabilities for detecting rooted devices. One can simply to help them with this framework hire react native developers Following the Identification of Rooted Devices, the Library will Conduct a Check checkRootManagementApps checkTestKeys checkForDangerousProps checkForBusyBoxBinary checkForSuBinary checkSuExists checkForRWSystem checkPotentiallyDangerousApps checkRootCloakingApps This is an Android-only API for detecting rooted phones and firmware unlocks. It also protects users from security risks, including device manipulation, rogue applications, and imposters. The react-native-google-SafetyNet wrapper plugin, which is a SafetyNet API wrapper, may also be used to validate the user’s device. The react-native-device-info plugin may be used to check if an app is being used on a mobile device. CSRF attacks are caused by the attacker’s integration of unauthorized cookies into the program or by unintentional cookies. It pushes users to perform undesirable actions while logged in to an online application. Prevent forgery attacks: To manage sessions, use JWT tokens. Make sure your app only reads the CSRF tokens you’ve saved. With an authenticated request to the server, create necessary token headers. When the login information is input, the program fails, causing credential data to be leaked. Make sure you have the following items on hand to prevent it: Protection against broken authentication: Approval with many factors and two steps. Granting access using cloud-based identification. When third-party libraries, modules, or APIs are utilized in a React project, there is always a risk. They undoubtedly aid us in the quick creation of features, but having your own set of security vulnerabilities may jeopardize your online application. Protect against components: Manually upgrade these libraries to the most up-to-date, secure, and stable versions. Replacing outdated versions of parts with new ones is also a good idea. : Developers frequently need to save data locally, and async storage is sometimes used for storing Accesskeys, access-tokens, and user tokens. However, because AsyncStorage is unsecured storage, information may be extracted from it. React Native does not provide secure data storage There are pre-existing solutions in iOS and Android, such as iOS Keychain and Android Keystore, which we are all familiar with. Storage Keys can be utilized for cryptographic operations once they’ve been stored in the Keystore, but the key material isn’t exportable. You may use the following NPM to utilize iOS Keychain & Android Secure Shared Preferences from . React Native Reverse engineering with an APK or app bundle file allows hackers to quickly gain access to our codebase. We can implement Pro Guard rules to prevent this. Your code is obfuscated by Pro Guard. As a result, if someone reverses engineers it, it will be unreadable, protecting you against engineering assaults. was also used to shrink the size of the APK by eliminating unnecessary code and resources. If your project includes a third-party library, you can use it. Android security: Pro Guard Nowadays, OAuth is increasingly often used for authentication between two applications that communicate with one other. How do servers know if a request is authenticated when it arrives? For you, simplifies the authentication procedure. OAuth permits authentication using usernames and passwords rather than exchanging passwords. Ways of authentication: OAuth 2.0 Bottom Line: React Native-based web apps are well-protected. It comes with its own set of costs and hazards. Follow the best practices of a safe lifecycle to make the app secure. Define and handle any threats, develop a security strategy, and design your security measures. Spend time developing a threat model for your online application since it helps to bring everything together. web development Also Published At: https://futurewithtech.com/securing-react-native-application/

How to Secure React Native Application?

Real estate has always had a reputation for being one of the safer assets. Regardless of the current happenings in the stock market, people will always require a roof under their heads and a stable job. Nevertheless, real estate transactions can become some of the most overly expensive and complicated, making the real estate market comparatively illiquid. Real estate has always had a reputation for being one of the safer assets. Regardless of the current happenings in the stock market, people will always require a roof under their heads and a stable job. Nevertheless, real estate transactions can become some of the most overly expensive and complicated, making the real estate market comparatively illiquid. That can all be done, thanks to tokenization. The process behind tokenization involves the ownership of an interest in real estate through the usage of digital tokens existing on a blockchain. The emergence of blockchain and tokenization offers several advantages over traditional methods when it comes to making deals on the real estate market. Some of these include enhanced security, streamlined management, better liquidity, and transparency. As beneficial as tokenization can be, it does come with a complex process on the legal and technical side of things. Let’s dive deeper into the world of tokenized real estate investing. What is Real Estate Tokenization? The process behind real estate tokenization involves creating virtual tokens on the blockchain and assigning them to a real estate property that already exists or is under construction. These tokens can represent an interest in real estate and be utilized to raise capital towards development investment, allowing a broader range of investors and developers to participate in the real estate market. In short, tokenization is a method that allows organizations to raise capital through crowd sales, which is essentially similar to crowdfunding, but with tokens available on blockchain technology. The goal for this feat is far more doable if funding becomes available in such a manner. The role of tokens for this industry would be to act as the equivalent of stocks, except without requiring any overly expensive intermediaries to be involved. These tokens can then be used as a loan, shares for a development company, or ownership of a property. The Advantages of Real Estate Tokenization Tokenization has the potential to reshape the glocal real estate market. It enables issuers and inventors some significant advantages of existing investment options and serves as a way to introduce a massive number of new investors into the market. Tokenization comes with several benefits that shall be discussed below. Liquidity One of the primary advantages of tokenization would have to be liquidity. For clarification, liquidity refers to how easy it is for investors to acquire or sell or asset. At the moment, real estate investment is considered illiquid. Due to that illiquidity, some people regard it as one of the more significant negative aspects of real estate investing. It impacts the price of investments command, imposing an illiquidity discount on the underlying asset’s actual value. With tokenization, it’s possible to regain some of the lost value to the illiquidity discount. That is possible by making real estate investment easier to buy and sell. Even a tiny improvement in the sales prices of these investments could lead to a rise in new value for issuers and resellers. Some features of real estate tokens merge to make these improvements a reality. Lower Cost of Entry What’s become known as sufficient capital will be changed when real estate becomes tokenized. A virtual token isn’t required to be sold as a whole unit. Instead, the code underlying the token grants permission for its subdivision, enabling the issuer or subsequent holders to sell fractional tokens at much lower prices because of the fractionalization. That paves the way for small investors to enter into the market, who were previously unable to participate, and allows for better opportunities for diversification for weather investors. Standardized Transactions With blockchain technology making tokenization a reality, the ability to buy and sell real estate tokens is implemented through standardized smart contracts. These smart contracts can’t be negotiated separately, and the terms are fulfilled automatically. That reduces the transaction costs considerably. Worldwide Investment Pool Through the power of tokenization, the pool of potential investors becomes a global phenomenon. Anyone with enough capital and internet connection can seamlessly participate in buying, holding, and selling real estate located in any location in the world. Transparency Blockchains can record all transactions that take place on their network. Whenever a token goes through a transaction process, all the participants become aware of it. For that reason, investors can search through a token’s history, pricing, and any other details concerning it’ transaction whenever they wish to do so. Security Since blockchain is a distributed ledger, no individual or organization can control the network and impose its own policies. Furthermore, the distributed ledger technology (DLT) uses advanced cryptography techniques that offer users excellent security. Each user is provided with a personal key that grants them access to their blockchain assets. That key is generally represented with a line of random characters (such as numbers and letters), making it very hard for outsiders to guess it. Immutability Once the transaction has been recorded and confirmed on the blockchain, it cannot be changed in any way. That provides investors with a much-needed assurance that no one can counterfeit transactions after it’s execution. Searching for Property One of the many issues encountered with investing in real estate comes from having to search for a property to invest in. There are plenty of marketplaces where they assess up for sale. If the assets are tokenized, they become listable for a centralized marketplace. The makes the investor’s job much smoother since they now have a seamless way to search for potential investments in one location. With this opportunity, investors gain access to search for potential investments found in other geographical areas and enable sellers to gain access to a massive pool of potential buyers. What Should the Tokenization Strategy Include? It’s essential to understand the tokenization strategy and familiarize yourself with some of its vital parts. Type of Interest The developers of a virtual token have the opportunity to choose what they should tokenize. That can include such things as the real estate property itself, equity interest within a legal entity that has ownership of a property, the mortgage for a property, and the rights to share in the profits generated by the property. There are more options, but these are just some of the many possibilities. To put it in another way, the range of opportunities is massive and diverse. Even so, keep in mind that it’s all dependent on the interest that is tokenized. That means you will face varying levels of regulations. For that reason, before an asset is tokenized, it’s crucial to know which of the ordinances are likely to affect you. Legal Entity Traditionally speaking, securitization of real estate relies on the establishment of a special-purpose vehicle (SPV), and there is a good chance of tokenization doing that. An SPV is a legal entity created for a single purpose, such as holding and managing real estate. An SPV can be a trust, corporation, limited liability company, limited partnership, or other entity. However, each of them has its pros and cons. If suitably structured, the SPV’s assets and liabilities are regarded separately from those of the developer for accounting, tax, and bankruptcy purposes. That grants the token permission to stand by its own merit as an investment without requiring the creditworthiness of any of the developers involved. Establishing the SPV, its ownership, and transaction between it and the developer is a complex process that requires the assistance of an experienced advisor. Smart Contracts Smart contracts are computer codes made on a blockchain that can automatically implement and execute agreements between users without requiring an intermediary. Since smart contracts are eternally attached to the blockchain, it’s impossible to alter them once published. As a result, these smart contracts are used to establish the characteristics and sales process for the token. It’s one reason why the creation of these tokens needs to be done carefully. If it launches with some issues, it could lead to total failure on the developer’s end and unforeseen consequences for the issuer and investors. The development of a smart contract needs to trigger the characteristic the issuer wants for its token. For example, if a token holder is expected to receive dividends or a share in profits, the smart contracts need to provide it. One thing you need to keep in mind is that smart contracts are not there to replace lawyers. There are substantial gaps between the requirements of law and the limitation of smart contracts. It’s crucial to be aware of the function that smart contracts can and cannot handle effectively. In some cases, a legal override may need to happen, while in other cases, the smart contract has to be altered to accommodate a legal requirement. Securities Regulations Since real estate tokens are certified as securities under various countries’ laws, they will be required to register with the regulators. In many cases, it’s possible to acquire an exemption from registration. Failure to register with the regulators could result in civil penalties and other severe issues. Tax Requirements While the Internal Revenue Service has published a general guideline regarding the taxation of digital assets such as bitcoins, several aspects of how U.S. tax handles the purchasing and holding of digital tokens remain uncertain. Issuers and investors need to take some time to consult a tax professional for assistance in creating a comprehensive tax strategy. Additionally, issuers need to be aware of any reporting requirements they could have, tax-related or otherwise. Property Location Of course, the location of the real estate property matters the most. The parameters of the location need to be considered not only from a practical standpoint but also from a legal one. For example, not every country out there permits protection for private property rights. As a result, minimal amounts of investors will become interested in purchasing property in those geographical locations. Consider whether or not the location of the property can satisfy all involved parties. Mortgage Issues If the property selected to undergo the tokenization process is subject to a mortgage, the issuer is either required to get the mortgagee’s consent or pay off the mortgage. However, if the tokenization of the property is considered a mortgage itself, then the appropriate laws will need to be observed. Anti-money Laundering and Know-Your-Customer It becomes necessary for issues behind digital tokens to comply with the Anti-Money Laundering and Know-Your-Customer laws in places they decide to offer their tokens. If relying on the securities-law exemption that only sanctions accredited investors, issuers must take appropriate steps to accredit their purchasers. That can also include actively verifying that investors are accredited investors instead of taking their words for it. International Sales Plenty of countries have established securities laws and AML/KYC regulations. That means the issues need to be mindful of the various regulatory requirements when it comes to launching their tokens in specific regions. For example, a security token offering that is legal in Europe could be considered illegal in the United States. Plus, it may be possible that one country could treat a token as security while another may not. Overall, depending on the token’s feature, it may be subjected to several other regulated money services laws and potentially commodity regulations. Before tokenizing a real estate property, you need to take the time to methodically plan a strategy. That way, you can ensure the smooth execution of the tokenization process. Conclusion Tokenization can become one of the most significant game changes in the real estate market. It can change the way people are investing in real estate all over the world. However, realizing that potential will all come down to how well blockchain developers managed to structure the whole thing. Tokenization has some hurdles to overcome, but it has the massive potential to reach new heights. The real estate industry still hasn’t entirely realized the immense potential behind blockchain-enabled tokenization for dealing with existing market issues. Still, tokenization has managed to provide the industry with some benefits.

In an extraordinary broad, well-coordinated and timed collaboration, law enforcement agencies of eight countries and the Europol have to takedown the globally distributed infrastructure Emotet had nurtured over the years. teamed together While the Europol’s announcement might seem trivial and abstract to some, only valuable to cyber researchers like us, it is worth noting that throughout 2020, Emonet potentially affected one out every five organizations worldwide. Often unaware, the infected companies had increased chances of being victims of ransomware. This news reflects the importance of global cyber task forces and joint interests to protect the public from cyber-threats that have caused losses of millions of dollars in damages and disrupted business globally. Emotet, which was once a Banking Trojan and became a full-blown botnet was the most successful and prevalent malware of 2020 by a long way.  Data from Check Point Research’s , shows that over the course of last year, Emotet impacted the networks of 19% of organizations globally. Check Point’s latest even revealed that the Emotet Trojan had returned to first place in the December top malware list, impacting 7% of organizations globally that month, following a spam campaign, which targeted over 100,000 users per day during the holiday season. ThreatCloud Global Threat Index The botnet earned its reputation for its not only dynamic nature and unique technical features, but also because of the highly organized criminal business model, it developed.  Instead of acting alone, the threat actors behind Emotet chose to collaborate with other organized cybercrime groups like Trickbot and , and together they became very effective partners in crime. Ryuk ransomware In this vicious coalition, Emotet, through its broad worldwide infrastructure, was responsible for gaining the first foothold within companies and organization all around the globe. This large base of infections was then sold to other cybercrime operations such as Trickbot, which was responsible for broadening the foothold within the compromised networks by lateral movement, dissecting and mapping them into industries and companies, and in turn selling those infected networks onto ransomware players such as Ryuk, leading to some very . high profile and publicized cases This has been the infrastructure behind the ongoing success of ransomware in recent years. attacks In November, found that Trickbot and Emotet laid the foundations to ransomware attacks against hospitals and healthcare providers globally, driving a spike in ransomware attacks worldwide. This is being done due to the abilities described here. Check Point Research In 2020 the Emotet botnet, which lured victims through phishing emails, sent over . The botnet constantly adjusted its phishing emails to reflect victims’ interests and capitalize on global events (e.g. the Covid–19 pandemic or major shopping seasons such as Black Friday). 150,000 different email subject lines So far, very little information has been publicly shared regarding the extent of this takeover. According to in the hours following the joint statement, evidence began to appear online of possible arrests made alongside takeovers of offensive infrastructure. If this evidence is conclusive, the damage to the Emonet infrastructure could be fatal. However, it is yet too early to determine. Europol’s announcement shows how close co-operation between security researchers, software vendors, law enforcement and government agencies can mitigate and even eliminate major cyber-threats and disruptive attacks which can impact all of our lives.  Based on these successes, we are optimistic that 2021 will give many more positive examples of how cyber-threats are being overcome. Europol´s statement Emotet in Numbers Emotet activity peaked this year during August-October with an average of 47,000 infection attempts spotted each month. In November, this number dropped to under 700 after Emotet took a short break. In the last two months, Emotet has been active with around 10,000 per month, which is than the amount seen earlier. almost 80% lower In parallel, we have also seen over 40% decrease in new Emotet C&C communication in the past 2 months vs. the peak period Geographical distribution Security Tips to Keep Your Organization Safe prevents attempts to exploit weaknesses in vulnerable systems or applications, protecting you in the race to exploit the latest breaking threat. Updated IPS helps your organization stay protected. Intrusion Prevention System ( IPS ) is essential though an incomplete security measure, which can leave your network open for attack. By taking a more comprehensive approach, which combines robust IPS functionality with a concerted patching strategy, network administrators can better equip themselves to handle ‘Patch Tuesdays’ and secure the network between upgrades and patches. Patching Conventional signature-based Anti-Virus is a highly efficient solution for preventing known attacks and should definitely be implemented in any organization, as it protects against a majority of the malware attacks that an organization faces. In addition, comprehensive at the highest security level is crucial in order to avoid security breaches and data compromises Endpoint protections: endpoint protection

The Disruption of Emotet and What we Know About it

With so many "something-as-a-service" options at our disposal for infrastructure, in 2017 we opted for to build our platform of e-commerce services. Our mission was, and remains, to build for e-commerce services what AWS built for web services, or what we call the commerce fabric of the internet. function-as-a-service (FaaS) Building with FaaS and only paying for function execution time rather than constantly running servers (i.e. ) allowed us to serve customers early on without incurring high infrastructure costs. These customers were large, household names and referrals from our founding team who had . Part of this transformation involved moving from the monolithic e-commerce platform IBM Websphere to a with open-source and custom-built software. serverless transformed digital at Staples service-oriented architecture E-commerce veterans who knew our founding team wanted to transform digital for their companies, which led us to build our platform of modular commerce services in 2017. Using serverless FaaS with supported these services reliably and efficiently, and it continued to support them through 2020 when we raised and attracted customers outside of our circle of friends. AWS Lambda our $9.5M seed round But as we raise more money (most recently ) and onboard global brands , life on the serverless backend is not as easy as it once was. As a result, some challenges that were inconsequential at the time are now more pronounced. In this post, I will explain how we direct these serverless challenges and show you how serverless FaaS powers . our $100M Series B like GNC our platform of commerce services Our Serverless Architecture The current iteration of the fabric platform can be hosted in either AWS, GCP, Azure, and even Knative since all of these are supported by the we use. However, in 2017 when we adopted serverless, AWS had the offering so we made the simple choice in choosing Lambda for FaaS. serverless framework most mature Flash forward to today and we still use Lambda and sparingly route requests through , a container-as-a-service (CaaS) environment. Fargate is mainly used when we can't meet latency service level agreements (SLAs) with Lambda due to cold start problems. However, since Lambda powers 95% of all processes within our platform, we've found ways to direct these issues which I'll talk about below. AWS Fargate As for the way our products are structured, a data store layer is used, followed by a business layer in which most logic is programmed as you would with any other backend scenario. Lambda orchestrates event-driven workflows at the business and data storage layers. The actual product offerings consist of commerce applications like a and , referred to as Co-Pilot Apps in the diagram below. (Co-Pilot is the name of the UI that merchandisers, marketers, and other business users interact with.) We also offer that fast-track storefront development. Each type of offering has a separate yet connected business layer. product information manager (PIM) order management system (OMS) e-commerce storefronts On the top level, each layer is supported by Lambda in a serverless manner. API gateway routes interface between them, and the logic layer and external services layer interface through integrations. Every action, process module, and element of the platform is isolated into standalone functions in Lambda. The resulting layout achieves full separation of concern, with a single gateway route connecting with a single layer action/process at any given time. This cancels out the most common issues with resource sharing and allows each action/module to scale independently. Managing Serverless There are numerous tools engineers can use to manage serverless setups of the type I've discussed thus far. However, mainly because it was one of the earlier market representatives, we decided to use to manage serverless infrastructure through . the Serverless Framework infrastructure as code (IaC) Adopting the Serverless Framework as our infrastructure modeling and standardization tool enables quick spring-ups of environments. Further, the vendor-agnostic nature of the framework leaves room for any migration toward a cloud-agnostic, client-requested offering down the road. Using the Serverless Framework, we could support this offering while maintaining the same variables for mushroomed fabric platform instances. In addition to these benefits, we found getting started with the Serverless Framework incredibly easy, even for a robust platform of applications like ours. If you want to try it yourself, just launch your terminal and install the . After that, a simple serverless command sets your environment up for configuration and management through the . A serverless.yml file is then created, which is where it all started for us in 2017! and APIs node package manager framework's CLI Below is what a typical serverless.yml file configuration looks like using the Serverless Framework. The scripting language used is proprietary serverless.js, specific for a node.js app running on a MongoDB data store layer. This setup is similar to our own. The provider section of the config file allows for the full exploration of cloud services providers. However, we continue to use AWS as our go-to provider as we've found that other providers cause capacity bottlenecks as we continue supporting and brands. After AWS is selected, each function across the implementation is associated with a handler and specific API gateways. more of the world's largest retailers Using this template has dramatically improved the accuracy and speed of infrastructure configurations as we scale with serverless. Serverless Challenges As good as the story sounds so far, we have experienced our fair share of challenges with serverless and continue to experiment with ways to maintain business efficiencies while improving capacity and performance. Capacity While our current setup has enough capacity to support existing customers, there's always concern about having enough serverless infrastructure to support more, larger customers---especially during . To get ahead of this, we are experimenting with augmenting Lambda with using serverless containers with AWS Fargate. holiday shopping bursts Amazon EKS Cloud-agnostic support is an option we are exploring as well. But before allowing customers to dictate their cloud provider, we need to better understand capacity with GCP and Azure. With customers calling the shots for infrastructure, capacity issues could also arise with AWS. For instance, if a customer selects an AWS region of deployment outside USA East and West, . burst concurrency diminishes Performance What makes serverless efficient for your business can cause inefficiencies with application performance, particularly when using Lambda functions. These inefficiencies occur during the cold start duration when Lambda is downloading your code and starting a new execution environment. To reduce inefficiencies, we have tested and implemented . One workaround we use for avoiding cold starts is periodic warmup events that counteract environment timeouts. We are also exploring ( ) to offset any latency caused by Lambda. However, while doing this, we are trying not to defeat the cost-benefit variable for which Lambda was chosen in the first place. several performance optimizations Lambda@Edge Lambda + Amazon Cloudfront Stick with Serverless?

In your coding journey as a beginner, you're sure to need help with something, whether it's becoming more familiar with a programming language you're trying to learn or simply getting an explanation of how to accomplish a task. In order to avoid unnecessary frustration, it is important to ask good questions. Here are 4 tips to consider when seeking help online: Don't Ask to Ask, Just Ask: A wrong way of asking for help is to . Remember nobody is obligated to help you so don't ask for help in a way that is designed to waste other people's time. Something like , is not cool. By doing this, you are questioning people's abilities and unnecessarily excluding others, it's like you're essentially saying: ask if you can ask questions 'Is there any Ruby expert here?' Well, see I have a problem Involving Ruby but I don't think I want your help
if you're not only a Ruby user but also a Ruby expert. Similarly, or Just ask already. Nobody would respond to you when you ask for help this way, because it's not efficient. Go straight to the heart of the problem and ask your question, you do not need to ask for permission to do that. don't just say 'hello' 'Hi, can I ask a question?' Don't Ask People to Solve Your Problem for You, Instead Ask for Guidance: Keep in mind that the overall purpose of seeking help from others is to learn and improve. This goal would be defeated if you're asking people to profer solution to your problem. Rather, ask about the particular thing bothering you about the problem. Say for instance, you're trying to build a website, don't ask " ". You are expected to have researched how to do this then come back and ask about the specific issue you encountered in the process of building a website. While asking your question, explain what you've done and the steps you've taken so far to resolve that issue. This way, people will know that you're respectful of their time because you've already tried to solve the problem yourself and will then (probably) proceed to help you from there. can someone teach me how to build a website? Provide as Much (Relevant) Details as Possible About Your Problem: When seeking help online, remember that no one can read your mind or anticipate what your issue is without getting the necessary information from you, so try to provide some relevant details when asking your questions. If this means you have to take a screenshot or include sample code in the question, then do it. Additionally, remember to explain the context so that people can identify exactly what your problem is. Try not to keep your questions vague, help people to help you by explaining yourself very clearly and in great detail. Ask informative questions. Furthermore, when asking questions online, go straight to the point, don't beat around the bush or ask indirect questions as you will only end up wasting everyone's time (including yours) by doing this. Be Courteous, Remember to Provide Feedback and Thank People for Responding: Always endeavor to provide feedback to everyone who responded to your question. Even if they ended up not being able to help, still thank people for responding because they didn't have to do so. Keep in mind that you might still have more questions in future so showing people that you appreciate their efforts now will encourage them to come to your aid next time. The fact that someone's response now isn't the help you needed doesn't mean that a response from them in future will not be the exact help you need. So always be courteous and remember to respond to people and say thank you. For more tips on asking smart questions online, consider checking these 👇 out: by Gordon Zhu.

4 Tips to Easily Ask for Help from Others in an Online Coding Community

The results, measuring accessibility and privacy protections, were not always great By Jon Keegan and Colin Lecher Image by Sam Morris Christine Meyer, a Pennsylvania doctor, has seen some patients come in recently with concerning symptoms: uncontrolled hypertension, spikes in blood sugar levels. The stress of trying to find an appointment to get a COVID-19 vaccine, she said, is “literally making them physically ill.” “Listen, if your blood pressure gets any higher over this vaccine,” she’s told them, “you’re going to have a much bigger problem than not getting a vaccine.” One big source of frustration: websites that are difficult to navigate for less savvy web users. Similar to other sites, the Pennsylvania site leads users to an interactive map of blue dots, which then leads out to pharmacies and local health departments with their own sign-up procedures. It’s a system with “nothing intuitive about it,” Meyer said. “You have an 80-year-old patient, all they’re trying to do is get a vaccine, and they have 50 different places to go try to sign up,” she said, “but no feedback on whether their sign-up worked, no feedback on how long it would take to get a vaccine through that sign-up.” Christine Meyer, a Pennsylvania doctor, has seen some patients come in recently with concerning symptoms: uncontrolled hypertension, spikes in blood sugar levels.

Blacklight, a privacy tool, scans sites for trackers and cookies. Lighthouse, meanwhile, measures a website’s performance and accessibility. Blacklight Lighthouse Pennsylvania’s site Pennsylvania’s vaccine portal performance score (17 out of 100) was in the bottom 25 percent of sites we tested and had the second-lowest score for accessibility in our tests. “While we are connecting more people to information and resources available online, we recognize that the time it takes to load a page may have increased,” Maggi Barton, a spokesperson for the Pennsylvania Department of Health, said in a statement. “We are actively looking to make further improvements to our information sources.” But, as anecdotes around the country of people struggling to make vaccine appointments suggest, Pennsylvania’s is not the only site with issues. The Markup found a range of potential problems with state sites around the country. Privacy Blacklight tests for a few different things, including the number of ad trackers on each site—meaning the tool can tell you whether third parties receive information about your visit to the site. Such companies then use that information to build a profile of your demographics and interests to use to target advertising. In this case, such trackers share information about people’s visits to COVID-19 vaccination sites. (You can see our data and read more about our methodology for Blacklight .) here , which is run through a partnership with a nonprofit organization, Immunize Nevada, 24 ad trackers and 45 third-party cookies. Ranking states by the number of cookies, Nevada has more than the lowest 46 states combined. Nevada’s website contained Nevada's, Utah's, and Hawaii’s vaccine websites all have substantially more than the average number of cookies Other states with poor privacy ratings were (10 trackers, 22 third-party cookies), (12 trackers, 11 third-party cookies), and (17 trackers, 37 third-party cookies). There were some sites that had no ad trackers or third-party cookies at all, such as Texas, New York, Kentucky, West Virginia, New Hampshire, and Puerto Rico. Overall, the average number of ad trackers was 2.8 and the average number of third-party cookies was 3.4. Utah New Jersey Hawaii Marissa Medeiros, a spokesperson for Immunize Nevada, explained that the nonprofit “uses digital advertising to educate and inform Nevadans about these vaccines, and we use Google Analytics to track the performance of these ads.” The site also interacts with Facebook, Instagram, and Twitter, Medeiros explained, which increases cookie counts. Tom Hudachko, a spokesperson for the Utah Department of Health, said in an email that trackers were used on the state’s site for web analytics purposes and that the site was consistently monitored for speed. Performance For performance scores, we used Lighthouse, a widely accepted website testing tool built by Google, to measure how well the sites work on mobile devices, calculating a score based on different metrics. We chose Lighthouse because it is an open-source, standards-based testing platform integrated with Google’s Chrome browser technology that can make qualitative measurements for lists of websites. Lighthouse performs a number of audits that inspect different aspects of a website’s operations and architecture and then calculates these weighted scores to generate a from 0 to 100. One test measures how long it takes for a page to load all of its elements and to be fully functional, measuring the time a browser spends waiting for various code, graphics, or data to be served to it—during which users may see an animated loading icon. We captured this performance score and averaged it out over 30 individual tests per state over two days, run from three locations (New York, Texas, and California). performance score One of the things that can affect a webpage’s performance is when a publisher “embeds” interactive features from other sites, such as a YouTube video or a Facebook post. The use of such third-party widgets can include but it can also and time spent waiting for a site to load. trackers and cookies cost the user in data charges Nevada’s vaccination page features several embedded YouTube videos and Facebook, Twitter, and Instagram posts that offer public health information, featuring health professionals answering common questions in both English and Spanish. Our tests show that Nevada’s page has the lowest average performance score of all the sites we examined. Several states with the lowest performance scores, such as Pennsylvania, Ohio, Montana, Washington, and Arizona, also featured embedded widgets, but rather than displaying videos or social media posts, these were third-party interactive maps for users to locate vaccine providers visually and find directions to providers. Holly Poynter, a spokesperson for the Arizona Department of Health Services, said in an emailed statement that the state has received positive feedback on the map but also offers a text-based list for finding vaccines. Accessibility Lighthouse also tests for accessibility, generating a weighted score ranging from 0 to 100, to measure how well each site has implemented code to help users with disabilities access the site. The vast majority of the pages in our test received high accessibility scores through Lighthouse, with 84 percent scoring 85 or higher (out of 100). site received the lowest average score (66 out of 100) in our accessibility tests. New Mexico’s States scored high on accessibility, although New Mexico, South Carolina, and Pennsylvania scored 75 out of 100 or below Still, while states have made an effort to accommodate disabled users, a recent survey by of state vaccine websites found accessibility issues on nearly all of the pages it inspected. And reported that blind users were having difficulty using various states’ vaccination pages because the sites used third-party tools such as embedded maps that did not meet states’ accessibility standards. Kaiser Health News and WebAIM NBC News Hurdles in performance and accessibility are a special burden for many who need the vaccine the most. Low-income communities of color, which have been hit particularly hard by the pandemic, tend to have lower levels of digital access and computer literacy. The elderly and people with disabilities, despite being first in line for the vaccine, are also some of the most likely to struggle through a complex sign-up process. And as vaccine eligibility expands and more people look for appointments, the problems will only compound. What Researchers Have Seen Tory Hogan, an assistant professor in health services at Ohio State University, said state health departments are facing a rapidly evolving crisis they were never financially or technically prepared for. Suddenly, state health department websites have gone from providing licenses to restaurants to becoming life-or-death resources for huge swaths of the country. “They’ve never required the infrastructure that they do now,” Hogan said. Hogan and other researchers of state health department COVID-19 websites last month, looking at how states were providing data on vaccinations and how simple they made the scheduling process. published an analysis The that, as of last month, only 20 percent of websites offered a centralized, online scheduling system. About 40 percent didn’t list vaccine providers with contact information, and almost 30 percent didn’t even link to vaccine information on their front pages. researchers found There are different ways to measure how successful a website is, and while Hogan said no site was perfect, some were better than others at guiding people through the process. Some states, like New York, have developed centralized health department systems that allow people to schedule a vaccine with multiple providers from one site. Most states, however, have implemented decentralized systems that point visitors to the websites of local health officials or pharmacies. All over the country, people are turning to digital communities, outside of the network of government and pharmacy sites, to figure out how to access vaccines, relying on and to find slots. third-party websites social media chatter Meyer, the Pennsylvania doctor, started a Facebook group to help people in the state struggling with the system to register for vaccination. The group has helped thousands make appointments so far, sending tips and tricks for signing up on various sites. “It’s a very systematic, agonizingly slow, tedious process,” Meyer said. But it’s the best system many people in the state have been able to find.

Testing the Perfornace and Privacy Settings of COVID-19 Vaccine Websites

One of the CDK's greatest strengths is the ability to create a library of components to be shared across your company or shared with the world on . But how do you create a construct based on other constructs in the same stack without forcing the developer to call a method for each one? That's exactly what aspects allow you to do. constructs.dev What are Aspects? The CDK uses a four-step process to convert your code into a CloudFormation template: construct, prepare, validate, and synthesize. Since aspects are used during the second step, you need to understand how the first two steps are related. When you run a CDK command, it starts by executing your code. Usually, this is some file in the project's directory where your App is created. This will create all of the constructs that you've added to your project, keeping only the level 1 or constructs for the next step. bin/ Cfn* The prepare step is where aspects are used. Each scope has a set of aspects registered to it during the construct phase. The CDK travels down the construct tree, and if it finds a registered aspect, it will pass in all of the constructs in the current scope and any child scopes. Creating the Dashboard Construct If you don't have the CDK installed, you can find instructions in the . getting started guide Now that you've seen aspects work behind the scenes let's create one of our own. We'll create a CloudWatch dashboard construct that dynamically adds widgets for every DynamoDB table in the construct's scope. Start by creating a skeleton project by running the following commands. mkdir dynamo-dashboard
cd dynamo-dashboard
cdk init app --language typescript Create the Construct First, create a new construct called . Create the class in and make sure it implements . DynamoDashboard lib/dynamoDashboard.ts IAspect Next, you'll need to add some properties to store the dashboard's state between calls to its method. The first property is a reference to the CloudWatch dashboard that will be updated. The second property will store all of the widgets that you create. visit private dashboard: cw.CfnDashboard;
widgets: Array<Widget> = []; Finally, add a constructor. It should register itself as an Aspect in its scope and create the dashboard construct. constructor(scope: cdk.Construct, id: string) {
	super(scope, id);
	
	// Register this as an aspect
  cdk.Aspects.of(scope).add(this);

	this.dashboard = new cw.CfnDashboard(this, `Dashboard`, {
    dashboardBody: ""
  });
} Implementing visit() Adding a widget to the dashboard requires three steps: find a free spot, add a widget object to the array, and update the dashboard body definition. Use the following method to figure out where the next available spot is. You can change the width/height values, but keep in mind that the dashboard is 24 units wide. widgets getNextPosition(): {x: number; y: number; width: number; height: number;} {
	let x = 0;
  let y = 0;

  if (this.widgets.length > 0) {
    const lastWidget = this.widgets[this.widgets.length - 1];
    x = lastWidget.x + lastWidget.width;
    y = lastWidget.y;

    if (x >= DASHBOARD_WIDTH - 1) {
      x = 0;
      y += this.props.widgetHeight + 1;
    }
  }

	return {x, y, width: 12, height: 6};
} Now you can implement the actual method. The first thing you need to do is make sure the node is a DynamoDB table. Since every construct passed into the visit method will be level 1, you will be checking if the node is a instance. visit CfnTable visit(node: cdk.IConstruct): void {
	if(node instanceof dynamodb.CfnTable) {
	}
} If the node is a table instance, you can create a new widget and update the dashboard. visit(node: cdk.IConstruct): void {
  if (node instanceof dynamo.CfnTable) {
    const position = this.getNextPosition();

    this.widgets.push({
		  ...position,
		  type: "metric",
		  properties: {
		    metrics: [
		      [
		        "AWS/DynamoDB",
		        "ConsumedReadCapacityUnits",
		        "TableName",
		        node.ref,
		        { label: "Read (max)" },
		      ],
		      [".", "ConsumedWriteCapacityUnits", ".", ".", { label: "Write (max)" }],
		    ],
		    view: "timeSeries",
		    stacked: false,
		    region: node.stack.region,
		    title: node.logicalId,
		    stat: "Maximum",
		    period: 300,
		    liveData: true,
		  },
		});

    this.dashboard.dashboardBody = JSON.stringify({ widgets: this.widgets });
  }
} Testing It Now comes the fun part, it's time to test your component. Go to your project's default stack and create an instance of the component. Next, add a couple of DynamoDB tables. Even though your method is looking for instances you can use the class since it creates a instance in its constructor. visit CfnTable Table CfnTable export class DynamoDashboardStack extends cdk.Stack {
  constructor(scope: cdk.Construct, id: string, props?: cdk.StackProps) {
    super(scope, id, props);

    new DynamoDashboard(this, `DynamoDashboard`);

    new dynamo.Table(this, `FirstTable`, {
      partitionKey: {
        name: "pk",
        type: dynamo.AttributeType.STRING,
      },
    });

    new dynamo.Table(this, `SecondTable`, {
      partitionKey: {
        name: "pk",
        type: dynamo.AttributeType.STRING,
      },
    });
  }
} Everything should be good to go at this point; run to send your stack to the cloud. Once it's done deploying, open up CloudWatch and find your dashboard. Now enjoy the fact that you don't have to manually add every table to it! cdk deploy Conclusion In this article, you've seen what CDK aspects are and how to use them to dynamically update resources. I haven't seen many other examples of aspects, but hopefully, you'll be inspired to create something awesome and share it!

An Intro to Dynamic CDK Dashboards

Introduction Logging needs special consideration and careful attention during micro-service development. Logs can provide comprehensive information about states, errors, and performance during a micro-service’s execution flow as it serves user requests. It is important to instrument code to add logging capabilities that can trace the application's execution. Adequate instrumentation is very important, and it should be a required coding standard. Logs should be ‘enough’ to give insights into the system without over-whelming the developers and the system. Guidelines Choose the Right Log Level Using the appropriate logging level makes logs easy to read. Log levels allow the developer to filter the levels based on the requirements. A developer investigating an issue will be interested in ERROR level logs whereas a developer making sure the business logic is working as expected, will be interested in INFO logs. Logging APIs use different logging levels to indicate severity but broadly speaking the following log levels can be used as a guideline: Normal logging of the operations, minimal server-side logging to ensure the application code is functioning normally. Keeping an eye on events through the system; need to know what is going on now with business logic. INFO: Some unexpected run-time error which should not occur during normal / healthy operations. This is not what our users expected; what went wrong in our business logic. ERROR: Some unexpected error that can occur occasionally even during normal operations WARN: If this happens during normal operations, it doesn’t seem right. Details related to application which can help with deeper analysis. Additional / detailed information will be useful in debugging any issue at a later time. DEBUG: Catastrophic / fatal error which causes termination of application code. This should never happen; what made our application crash and / or become unrecoverable. FATAL: Efficiency Remove unnecessary logs: logging is very easy to implement but once developers add logs temporary logs or additional logs, don’t forget to remove them. Avoid logging redundant fields / information: if there are other fields in a different log line that can help correlate logs, avoid redundant information. Log verbosity can be tailored: depending on your audience, logs can be made concise or verbose. E.g. if target audience is developers/DevOps/SRE, then event log time can be abbreviated like whereas if the audience is business analysts/non-technical, then use . eT=2021-09-12T13:00:00:000 eventTime=Sunday, 12th September, 2021 at 13:00 UTC Consider your space/cost constraints: Excessive logging can generate large log files and can incur large recurring costs to the business. Java full stack traces can take up considerable payload space. Instead of the entire stack trace, consider logging error code/status/message in error handling code. Logging in a loop: Do not log the result of every iteration of a loop (especially for large loops). Consider logging a summary at the end of the operation. Performance Correct use of a logging framework should have none to almost negligible impact on application performance since a logging framework should consume minimal resources. Generating log messages should not slow down the application. Using method invocation on complex objects is not recommended. String operations can be surprisingly expensive, so this optimization is important. toString() Ensure that the log statements do not cause failures themselves e.g. check that object is not null when using in a log. toString() Logging frameworks offer settings to show the class, method, and line number that generated the log output. Since this is an expensive operation to produce this setting, it should be switched off in production. Security and Privacy Avoid logging Sensitive, Confidential or Personally Identifiable Information (PII): Do not log SSN, credit card numbers, phone numbers, addresses. Avoid logging Authentication information: Do not log any credentials, keys, access tokens etc. that was used to authenticate or authorize the user. Avoid Logging User Generated Content (UGC): Do not log chat message contents, email contents, etc. which can contain confidential data. Sanitize data: Consider using techniques like hashing, scrambling or pseudonymization to remove any association of the data to a particular user. Log data cannot be traced to a particular user. Quality and Measurement Code Review: Develop logging standards for the team and carefully inspect log lines during code review process. Pre-production Environment Test: If there is a staging or a pre-production environment, check newly added or updated logs (level, information, etc.) before deploying the build in a production environment. Monitor what you log:  Having simple mechanisms and tools to allow the developers to monitor services from a logging point of view will inculcate good habits: dashboards to log daily/weekly/monthly log size by micro-service. Dashboards to count the number of logs per level. Trends for size of items logged. Conclusion Logging is a very powerful tool that developers can use to gain insights into their micro-services, and it also serves as an important diagnostic tool. Logging at the appropriate level with enough data and context is equivalent to placing cameras at various spots in the code. Logs are indispensable when it comes to debugging issues and gauging system performance. Reference https://cheatsheetseries.owasp.org/cheatsheets/Logging_Cheat_Sheet.html

Five Guidelines for Robust Logging

“Robots” are here, and they are here to stay. Artificial Intelligence (AI) is silently taking its roots in the modern world. It has created smart homes and offices, boosted security with facial recognition technology, assisted drivers in navigating rush hour traffic, and made people like or buy things through behaviour-reading predictive algorithms. While AI is making a lot of things easier, some people fear that these “robots” will take over their jobs. With AI demonstrating its incredible ability to mimic or even surpass human capabilities, their fear. Or is it? A study published in 2020 projects up to 85 million jobs could be lost to these smart machines. On a positive note, the same study also projects that the new division of labour between humans and machines will create 97 million new roles to offset what was lost. World Economic Forum There is historical data to support how AI can lead to more jobs even in the Business Process Outsourcing (BPO) industry, a veteran IT leader said, citing how the first Industrial Revolutions could have a massive negative impact on human work. “People were scared that the development of machines during the Industrial Revolution was going to take away jobs, but instead it changed the way we work and in fact created more jobs,” said Henry Vassall Jones, Emapta’s Chief Technology Officer. A McKinsey Global Institute published in 2017 shared some proof of this outcome, showing how the rise of personal computers, which was predicted to cause massive job losses, created even more jobs (19.3 million) in the US than it destroyed (3.5 million) from 1970 to 2015. research It even gave rise to some of the industry giants today like Oracle, IBM, and Microsoft. The same goes with rise of AI or the so-called “Fourth Industrial Revolution,” the McKinsey study said, stressing that adopting smart automated systems will have varied effects in different industries. It also suggested that parts of work, not actual job roles per se, will feel the impact of AI adoption. “Activities most susceptible to automation include physical ones in predictable environments, such as operating machinery and preparing fast food. Collecting and processing data are two other categories of activities that increasingly can be done better and faster with machines,” the paper showed. “It is important to note, however, that even when some tasks are automated, employment in those occupations may not decline but rather workers may perform new tasks,” it added, stressing AI will have lesser impact on roles that involve managing people, applying expertise, and social interactions. Some of the industries that are projected to see employment growth with the rise of AI include IT professionals, technology specialists, engineers, scientists, accountants, machine educators, artists, healthcare providers, builders, and manual service jobs in unpredictable environments. Harnessing AI to create working “Iron Men” In the end, AI will always just be a tool, added Roy Figueroa, whose job as Emapta’s Client Solutions Director includes managing and dealing with leaders from different industries. These smart machines, he stressed, will always need human intervention. “AIs need to be programmed correctly to be useful and efficient. And they’ll need constant reprogramming as our needs change. AIs have and will continue to replace humans in the performance of routinary tasks just like machines took over the production lines in factories,” he said. “However, the software engineers and the people involved in the training of AIs will always be a necessity just like the mechanical engineers are now to machines or robots in production lines,” he added. Henry added that while AIs can collect and organise data faster than humans, in the end, it will still be the people who will have to interpret the information. “A machine can do things faster. It can analyse much larger data sets, provide analytics and statistics which would take a human longer, but also somebody needs to be there to interpret, and it’s still going to be the people,” he said. The same goes for labour, a by accounting firm PwC explained, noting that the combination of AI and humans – “Iron Men” of sorts – will become the new normal in the workforce of the future. 2018 research “A human engineer defines a part’s materials, desired features, and various constraints, and inputs it into an AI system, which generates a number of simulations. Engineers then either choose one of the options or refine their inputs and ask the AI to try again,” it said. AI will need continual tweaking and customising for it to be adopted by businesses, the study added, which will need “functional specialists” like economists, analysts, and traders who can identify where the AI can best support human asset managers, help design and train the AI. An AI-augmented BPO industry Henry believes the BPO industry will play a major role when businesses begin to fully embrace AI. Offshoring firms like Emapta will be able to respond to a potential increase in demand. “I think that the start-up industry and the IT sector can definitely benefit from Emapta’s services because we’re able to provide skilled resources that would be able to work on these projects,” he said. AI will also help workers of the BPO industry to reduce routine or repetitive tasks, like data entry, transcription, approvals, request updates — tasks that consume precious work hours — so the workers can focus on the most important aspects of the job. “A closer review of what everyone does versus what available technology offers in terms of data management, and customer relationship management, will show that we perform a lot of repetitive tasks that otherwise would bog down businesses,” Roy added. Roy said harnessing AI and bots is aligned with the clients’ primary objective when outsourcing or offshoring, which is to reduce cost through employment of less expensive but higher quality team members. Henry and Roy also agree that if there’s one thing that can’t be replicated by AIs is to have an emotional connection to the work being done.

‘Iron Men’ to Rise in AI-Augmented Business Landscape

This story is a part of of interviews. The series is intended for tech professionals contributing the most insightful Hacker Noon stories to share more about their writing habits, ideas, and professional background (and maybe a hobby or two). Hacker Noon's Meet the Writer series If you too would like to start contributing to Hacker Noon, . you can do so here So let’s start! Tell us a bit about yourself. For example, name, profession, and personal interests. I am Roxana Murariu, a Romanian Web developer living in Dublin with my family. Interesting! What was your latest Hackernoon Top story about? The article, , was about metaphorical thinking. I wrote about the pervasive usage of war metaphors to describe the current pandemic situations, how we use metaphors as instruments for creativity and how metaphors express social models. Metaphors are Water: The Hidden Power of Thinking in Metaphors Do you usually write on similar topics? If not, what do you usually write about? I write about parenting, self-improvement, and tech on . I crosspost relevant articles to HackerNoon. my blog Great! What is your usual writing routine like (if you have one?) Depending on the topic, an article can take from two hours to 20-30 hours of researching, writing, editing, and formatting. I do this work across weeks as I have multiple drafts opened at any moment (for example, now I have around 35 current drafts). These drafts grow organically. Whenever I come around to an interesting concept, I either note it in a specific draft or open a new one. I read most of the articles from and to absorb good habits about writing. What suits me best is to do a little bit of work every day. This work does not necessarily involve writing, as I research extensively for some articles. the Writing Routines website Mason Currey's books I write my articles in Microsoft Word, edit them with Grammarly Premium, read them aloud to catch errors, and then I leave them alone for at least a night. About the editing part, I have no issue cutting whole paragraphs if they don't help the article ( , as William Faulkner wrote). Another quote about writing I follow is by William Zinnser from his extraordinary book : "You'll never make your mark as a writer unless you develop a respect for words and a curiosity about their shades of meaning that is almost obsessive." "in writing, you must kill all your darlings" On Writing Well Writing gives me great joy, as it is the perfect outlet to recharge after an intensive day at work. Being a writer in tech can be a challenge. It’s not often our main role, but an addition to another one. What is the biggest challenge you have when it comes to writing? I have drafts with tens of pages (anything from 30 to 50 pages) of unedited content, with a melange of Romanian and English, as I added my ideas and research notes from previous weeks. Every time, with no exception, when I open these heavy drafts, I sigh and tell myself: why do I even bother? What original thoughts can come out of this? In time, I learned to see these distorting questions as my cue to simply start working and as a challenge to condense the complex knowledge from those drafts into eight or ten minutes worth of reading. What is the next thing you hope to achieve in your career? I'm trying to start a business with my husband to have a sustainable income from it. Our first project is a narrative-driven fantasy role-playing game with collectable card elements. This project nurtures my creative writing side as I develop the characters, dialogue, lore, and quests of the game. Wow, that’s admirable. Now, something more casual: What is your guilty pleasure of choice? is a fantastic low-carb ice cream brand. Oppo Do you have a non-tech-related hobby? If yes, what is it? Children's books! Thanks to my daughter, I discover new children's books quite often. Rich topics and mindful conversations are pouring out of these books, from emotional literacy skills to stories about friendships, bullying, death, diversity, inclusion, religion. And did you know that Dr Seuss, in his , knew precisely how to solve one of the most significant programmer's puzzles, naming a variable? Look no further than the muddle puddle tweetle poodle beetle noodle bottle paddle battle! Fox in Socks What can the Hacker Noon community expect to read from you next? Tech essays ( and the future jobs of the 21st century), a new series about debunking science myths, and more. the Polanyi's paradox Thanks for taking time to join our “Meet the writer” series. It was a pleasure. Do you have any closing words? Thank you for having me. People crave meaning and belonging. Thus, we craft our identities based on our tribes. Nowadays, we live in a world more divided than ever before, as we have access to social media applications that hold a wealth of choices for tribes. This leads to virtual social bubbles and echo chambers where our biases are distorted and amplified because engaging with social media algorithms is autocatalytic (the process feeds itself). To break free from this process, I often question and try to change my biases and assumptions. I also regularly read an essay written by Paul Graham on . So, I would like to end this interview with a question: when was the last time you changed a deep-held belief? keeping our identities small This story is a part of of interviews.

Meet the Writer Roxana Murariu: "We Craft our Identities Based on our Tribes"

This story is a part of Hacker Noon's . The series is intended for tech professionals contributing the most insightful Hacker Noon stories to share more about their writing habits, ideas, and professional background (and maybe a hobby or two). Meet the Writer series of interviews If you too would like to start contributing to Hacker Noon, . you can do so here So let’s start! Tell us a bit about yourself. For example, name, profession, and personal interests. My name is Anndy. I’m a business strategist and experienced serial entrepreneur with over 15 years of experience in Asia. I’ve worked in various industries for local, international, and publicly traded companies. I am currently Chairman of BigONE Exchange and Chief Digital Advisor at the Mongolian Productivity Organisation. I’ve also written a best-selling book titled “Blockchain Revolution 2030”. With my co-authors, we share insights on how blockchain technology plays an important foundation for the Fourth Industrial Revolution. I recently joined the EG Association, a social impact-driven organization that aims to use cryptocurrency to do good. To date, we have deployed more than $3 million supporting social impact initiatives on the ground. Interesting! What was your latest Hackernoon Top story about? focused on the rise of so-called reflective tokens, which are starting to be used more and more by crypto startups, such as SafeMoon. The tokenomics model differs significantly from that of other DeFi tokens. In simple terms it works by automatically charging a tax, which is usually 10% on each transaction. My recent article The reflection mechanism is a relatively new concept in cryptocurrency circles, and it still requires a lot of fine-tuning before it can be widely adopted by other projects. However, in principle, it reduces panic selling to a bare minimum, which could be significant for the DeFi industry. Do you usually write on similar topics? If not, what do you usually write about? I think it’s important to write about the diversity of subjects in the blockchain and crypto industry, as it’s a sector that growing so quickly and with a lot of opportunities. I’m fascinated about ‘connecting the dots’ between business and technology, a great example being the use of DeFi and NFTs in developing an open metaverse. Great! What is your usual writing routine like (if you have one?) Before starting to write I believe it’s important to have a routine for reading each day. I try to find time to catch up with the main news headlines, as well as the main crypto news sites like Cointelegraph. Then when I come to writing I find that reading helps make my articles both accessible and valuable. I also get my inspiration from the governments that I am advising, their problems and questions become part of my writing content too. Being a writer in tech can be a challenge. It’s not often our main role, but an addition to another one. What is the biggest challenge you have when it comes to writing? The challenge is often one of translation, explaining technical details around say a new form of tokenomics to an interested but non-technical audience such as crypto investors. What is the next thing you hope to achieve in your career? I want to share the right kind of crypto knowledge with people. Right now many of the people I see in various communities are not being real. Some of them want their government to be decentralized, others want to be rich overnight by doing nothing, then some others are just here to create FUDs. If proper information is being shared and the users are aware of what is really happening, such ‘behaviours’ would be minimised. Maybe this is not a career goal, it is more like an industry-wide goal that I set for myself. Wow, that’s admirable. Now, something more casual: What is your guilty pleasure of choice? Since getting grounded and not being able to travel, I have been very involved in donations and charitable works. In fact, those who know me, know that I am donating more than I spend. My guilty pleasure, for now, is walking into Hermes, buying a few pairs of shoes instead of donating. Then again, Zoom meetings did not need me to travel much, maybe a comfortable Uniqlo t-shirt would do just fine. Do you have a non-tech-related hobby? If yes, what is it? I enjoy travelling, meeting new people from all walks of life, and sharing ideas. What can the Hacker Noon community expect to read from you next? I’m always on the lookout for new topics in crypto and blockchain that illuminate and inspire my readers! I might be talking more about metaverse and gameFI. Let’s see. #Thanks for taking the time to join our “Meet the writer” series. It was a pleasure. Do you have any closing words? “The time is always right to do the right things.” I hope to gather more like-minded people to do that together for the crypto industry. Let’s work together to make crypto better! Lastly, it’s great to join the Hacker Noon community and to share my writing on crypto and blockchain.
