- Richard Clarke, Former White House Cybersecurity Advisor “If you spend more time on coffee than on IT security, you will be hacked. What’s more, you deserve to be hacked.” Technological advancements have equipped us with powerful tools and revolutionized the way we communicate, do business, and make transactions. However, with great power comes great responsibility, and providing users with a safe & secure mobile application is one aspect of that still needs big improvement. Ever since the Facebook Cambridge Analytica controversy, people are now even more concerned about their data security. mobile app development The are quite evident but sometimes it comes at a cost of compromising user data. In the pursuit of developing an exceptional look & feel, application creators often overlook the importance of mobile app security. This can prove to be rather damaging for both the user and the business in the long-run. benefits of mobile applications If you are on your way to making an app for or Android, you need to take foolproof measures in this department. Here are some ways you can incorporate these measures into mobile app development. iOS The Mobile App Security Checklist Secure the Source Code . No matter how much time and money you invest in an application, a weak code can ruin it all. So what do you do? Make the app’s source code secure by reducing its chances of being reverse engineered. Imagine installing a million-dollar home security system and then leaving the main gate open One way to achieve mobile app security is . This is a method that turns the source code into incomprehensible symbols and letters, making it almost impossible for hackers to decode it. This security measure is available in Android’s and also for iOS mobile applications. Obfuscation Pro-Guard Secure the Database In the tech world, . Be it Google, Facebook, or Amazon, they all rely on using to run their business using . They use user information like age, gender, location, preferences, and payment details to predict their behavior and act accordingly. Chances are, your app will run on this data too. data is king big data Artificial Intelligence (AI) Make this valuable information hack-proof by using technologies like when developing an application. end-to-end encryption Check Third-party Code’s safety Why bother writing new code, when it’s already available? It’s common practice to use pre-written code available online for free or even purchase it. This, however, is not always the right thing to do. According to a , only 16% of developers fully trust outsourced codes. survey Refrain from using and if they are required, make sure it’s not compromising mobile app security. third-party codes Choose APIs Wisely It is one of the backbones of mobile app development but it can also be a security-nightmare. Go for s that are compatible with the application’s platform and use an to make the app more secure. API API Gateway Get into the Hacker’s shoes It’s good to think from a user’s perspective when developing an application but it’s equally important to think like a hacker. Look for weaknesses & loopholes in your code, try to reverse engineer it, and imitate a cyber-criminal. Repeat this process until you are satisfied with the code and confident that it will not risk mobile app security. Test, Test and Test again It’s never perfect. Studies suggest that over . One major reason is that programmers don’t perform enough tests. 60% of developers think their code is vulnerable to cyber-attacks They often leave it to the QA team to look for security loopholes, which is not a healthy practice. App security should be a priority and checks should be performed repeatedly at every step. Why Should you Care about Mobile App Security? “It takes 20 years to build a reputation and few minutes of cyber-incident to ruin it.” – Stephane Nappo Firstly, its the moral responsibility of the business owner to protect user data. Besides harming the consumer-seller trust, an information leak can cause financial and mental damage to a user too. Secondly, the regulatory authorities are now taking cyber-security seriously too. Ever since the Facebook Cambridge Analytica fiasco, there are harsh for tech businesses that are not compliant. penalties GDPR The security measures mentioned above are part of the bigger plan. Technology is changing at a fast pace and cyber-criminals are constantly evolving too. Mobile app developers need to stay up-to-date with the latest skills & tools. To develop an app that outsmarts any sort of security breach, you need to up the ante & stay one step ahead of the hackers.

How to Ensure Mobile App Security - Checklist for Developers

This entry to my ever-growing repertoire of online nonsense bears many interconnected and equally-as-good titles: Why Bitcoin is Doomed To Be Censored Similar to The Secret, the grass-roots revolution of Magical Internet Money will find an epic doom as it’s regulated. Further and further it becomes an unwieldy monster against the conventions and institutions that define our social structures — further and further it will be locked down, measured, and persecuted. Bitcoin and cryptocurrency represent the people taking back control of their finances against banks and intermediaries — something that the ruling class will never allow, at least with any scale. Some geeks in some basements literally bred you a function to become unequivocally free of governments and finances, and those governments and financial Gods are closing in on their prey as we speak. It’s the same as any other financial revolution that’s existed — however briefly or ‘flash in the pan’-ly in the past, and any other future revolution that could at least arguably sever the commands and controls of the bourgeoisie. This includes things like the October Revolution. This is the bankers and politicians securing their class — not necessarily themselves, in the case where we behead everyone who annoys us (not out of the question) — but like a poisonous frog dying to save his species, the rich protect their class, for the future rich. Why Your Life-Savings Meds Leave You Broke Again, aside from maybe marketing as an art, pharmaceuticals and antibiotics were some of the most important miracles of science and invention (and, at times, sheer luck) (read: not God. Not any other higher power.) in the past memory of history. These have been hijacked and served now only through multi-national corporations that serve their stakeholders and shareholders before serving the common good. There’s no drug coverage in Canada — at least not without being absolutely desolate and devoid of income — as government programs scale with income and you’re stuck footing the bill. There is private insurance — but that’s a scam for another entry. Personally, and using ‘I’ statements rather than hearsay, my meds that keep me able to get out of bed without being absolutely catatonic and berated by hallucination and delusion are critical. They’re indeed $2414 every three months. That’s about half of the poverty limit according to the Canadian Revenue Agency. Egregious. These are individuals at the tippy top of our social and monetary structure ensuring the longevity of the structures themselves. This is keeping the poor poor for the sake of the exploitation itself. Why Socialism Will Never Die The eternal battle of collectivism vs individualism sees shifts back and forth in public sentiment — witnessing decentralization poke its head up with crypto and all things crypto, we can see the push back from the other half of the world’s combatants. These folks pushing for state-controlled everything and Big Government will drive their pitchforks until we see things recentralized. It’s the Dark Side (Or Light Side? Depends on which side you subscribe to..) of Star Wars. A New Hope, The Empire Strikes Back. Push forth, push ho, push back, push again — back and forth, indefinitely and forever. Why You Will Always Be Lower-Class The chief objective of a revolution is for the middle class to overthrow the upper class. By and large, aside from really (really) (questionably so) over-covered specific instances where someone ‘makes it big,’ this is the cycle we see ourselves in and see ourselves repeating. The slaves remain the slaves. The features of slavery itself change over time — from straight-up no rights, to indentured servitude, to our current flavor of debt slavery. I’ve written about it extensively before — but in short, nobody who fought and died for our current flavors of government had envisioned countries where people would need to owe in order to own capital. The Single Worst Thing One Can Realize It’s all pointless fighting for individualism in a collective scope. ‘If you can’t beat ’em, join ‘em.’ Announcement I’m thinking of running Libertarian in my local jurisdiction. Seriously. I’ve become absolutely disgusted with certain paradigms and structures. Time to destroy them from the inside, and rebuild. didn’t you mention a Libertarian revolution and associated fundraise? Ha, ha!

The Eternal Battle of Collectivism vs Individualism

Decentralized finance or DeFi, for short, has emerged over the last year, building significant momentum over the year as the Total Volume Locked in the sector has surpassed over $35 billion in comparison to $1 billion in February last year. Newer platforms like Fusion and Fantom are evolving the DeFi sector with interoperable and scalable solutions such as liquid staking, cross-chain swapping, and more. Fusion’s DCRM technology and the Fantom foundation’s DAG-based smart contract platform are expected to grow the Defi sector tremendously. Both the networks aim to allow users to execute sophisticated financial functions while solving the scalability and interoperability issues of existing blockchain solutions, making way for the Internet’s new age. The Fusion Project Founded in late 2017, the Fusion project proposed establishing a platform-level public chain where the tokens’ private keys on multiple blockchains can be securely moderated in a distributed fashion using its proprietary solution. DCRM At the core of the Fusion project’s design is a distributed control rights management system ( ), smart contracts creation, and hierarchical hybrid consensus mechanisms ( ). The project’s strategy is meant to catalyze the emergence of the Internet of Values. DCRM HHCM Fusion DCRM and HHCM Protocol The Fusion project implements HHCM to ensure unpredictable randomness of book-keeping nodes, hence bolstering the system’s security and functionality. The HHCM enables the following for the Fusion project. Adds a DCRM layer Advances the current smart contracts Builds a distributed and crypto financial establishment Achieves a Crypto financial DApp layer The Distributed Control Rights Management protocol at the heart of Fusion transfers digital assets control to the network’s decentralized nodes management. The distributed generation and storage of private keys on the Fusion network control the access of private keys. Hence no single node on the network can gain control of the digital assets. Fusion also utilizes crypto-asset mapping. Crypto-asset mapping actively generates tokens used for bookkeeping on the network for controlled objects. Therefore, tokens on the network can freely interact with mapped assets. Moreover, Fusion has also implemented distributed control with its Lock-in and Lock-out mechanism. With the lock-in and lock-out process, users can simply validate asset ownership by generating a private key with the distributed sharding algorithm found in the DCRM. Users transfer the control of their assets to the DCRM through a centralized management framework. After the transference of authority is completed, a smart contract will update the user’s account on Fusion. The Team behind Fusion The Fusion foundation was introduced by DJ Qian, the CEO of a popular blockchain incubator, BitSE. BitSE was nominated as the top fintech startup globally and awarded with the year's most powerful blockchain infrastructure. BitSE has also led to the establishment of VeChain and QTUM. Most of Fusion’s success can be attributed to its technology and the open-source community behind it. The developer community has actively improved the platform’s protocols and features. Fusion has a group of honest developers called the FOSC. The group comprises some of the best open-source developers, translators, designers, and more. Fusion Use Cases The DCRM has several use-cases for storing cryptocurrencies. By combining DCRM with the ability to validate asset ownership, Fusion inherits a diverse set of use-cases. Anyswap Based on Fusion DCRM technology, Anyswap is a unique, completely decentralized, cross-chain swap protocol that provides users with automated pricing and a sophisticated liquidity system. The Anyswap decentralized application is compatible with notable blockchains such as Fusion, Binance Smart Cain, Ethereum, and Fantom, making it the first true cross-chain DEX. Anyswap acts like a decentralized cross-chain bridge. Users can deposit any coins into the protocol and mint wrapped tokens in a decentralized ecosystem. Users can also instantly swap from one coin to another without any risks to anonymity or privacy. Additionally, Anyswap also offers a liquidity provider that adds and withdraws liquidity into swap pairs on the application. Furthermore, Anyswap exchanges different pairs on each of its supported blockchains. The newer version of Anyswap will offer direct pairings in addition to pairings with base coins of Fusion, Ethereum, Fantom, Huobi Eco Chain, or Binance Smart Chain. Note that Anyswap users have to pay the gas fee for the respective blockchains they deal with. Also, users have to pay 0.4% of the sum they transfer, where 0.3% is assigned to liquidity providers, and 0.1% goes to Anyswap. Chainge Based on Fusion’s DCRM technology, Chainge offers instant coded financial services that span multiple blockchains such as Ethereum and Binance Smart Chain. With zero investment required, users can freely leverage power-coded finance services by using the free tokens provided to them for joining the early adopters waiting lists. No upfront investment is required to leverage the power of coded financial services as users can utilize free tokens provided for joining an early-adopters waiting list. Interestingly, users can seamlessly access services like margin trading, loan acquisitions and easily trigger digital financial instruments' liquidation. Additionally, users can access a myriad of wealth management features like self-customized crowdfunding or value distribution formulas through Chainge’s sophisticated yet user-friendly interface. Users can also provide financial services as a coded bank by providing loans, escrow and protect their friend’s account’s security with multi-sig services. Chainge simply banks the unbanked and allows users to build their own digital bank. It should be noted that Chainge is invite-only at the moment based on POIP, but you shouldn’t worry because you can click and use my referral in order to get some Chainge tokens, (thank you). on this link Is Fusion a Good investment? Fusion’s technology is easily one of the most sophisticated systems existing in the cryptocurrency market. The FSN token is an excellent investment based on its use-cases, its solution to interoperability, scalability, and usability. By investing in FSN, you are investing in its adoption. Although the token is ranked at 430 by Market Capitalization, the token has gone up in value at the time of writing, priced at $0.75. Fusion token accumulates a market cap of over $36.8 million with a trading volume of almost $16.5 million. Moreover, the token has taken a bullish run after breaking the resistance level at $0.6 after 3.5 months. It’s plausible that the token will go through price corrections. For a project of this level and activity, the price is considerably low. However, paired with the ideal tools, you can make this investment the right decision. Source: https://coinmarketcap.com/currencies/fusion/ The Fantom Project Fantom strives to stand out from the conventional block ledger-based storage infrastructure by employing a sophisticated DAG-based protocol called the Lachesis Protocol. The Lachesis protocol operates on the Fantom Opera chain. It intends to enable applications built on top of the blockchain to experience instant transactions and negligible transaction costs for users across the board. The Lachesis protocol allows Fantom’s mission to deliver an interoperable and scalable solution to the world. Fantom has proven to achieve a transaction time of under two seconds. Moreover, Fantom can process thousands of transactions per second to scale to hundreds of nodes on the network. Fantom delivers the first DeFi stack built on top of an aBFT consensus mechanism, making it the fastest, cheapest, most reliable, and most secure platform in the ecosystem. Users can use their FTM to mint fUSD and access DeFi tools, use their fUSD to trade synthetic assets, or lend it to earn interest and borrow synthetic tokens. Let us discuss some of the core features of the Fantom ecosystem. fUSD fUSD is a stablecoin on the Fantom network that serves as the gateway to Fantom’s Defi Platform. Users on the Fantom network can easily mint fUSD by locking up their FTM. Moreover, fMint also allows users to use fUSD as collateral to mint synthetic assets. fSwap Users can instantly buy synthetic assets from the ease of their Fantom wallets. Users can use their FTM or fUSD to trade over 170 different assets and tokens, including fBTC, fETH, and other notable assets. fLend Users can seamlessly lend FTM and fUSD to the liquidity pool and earn passive interest on their capital. Moreover, users can use fUSD to lend synthetic assets and trade on fSwap from their Fantom wallets’ ease. Fantom Consensus Mechanism — Lachesis Protocol The Lachesis Protocol at the core of Fantom is an aBFT consensus algorithm proposed by the Fantom team. The aBFT consensus algorithm enables the following features: The Lachesis Protocol essentially stores a Local Acyclic Directed Graph that comprises event blocks, each composed of transactions on the network. The DAG then monitors the happen-before relation between transactions and computes the exact final order of independent transactions on each node. Additionally, The Lachesis Protocol dramatically saves time by making validators on the network periodically exchange the monitored transaction and events with nodes. Interestingly, Fantom also employs the proof of stake consensus protocol to secure the network from potential Sybil attacks with a minimum requirement of 3,175,000 FTM from validators. The Team Behind Fantom Founded in 2018, Fantom operated from Seoul, South Korea, as a blockchain developer team striving to develop a new consensus algorithm. The Fantom Foundation team, led by their CEO, Michael Kong, comprises engineers, scientists, researchers, designers, and entrepreneurs. Fantom Use Cases With the emergence of various viruses and illnesses worldwide, Fantom has been expanding as a smart medicine solution to showcase Fantom Technology and Blockchain technology's numerous use-cases. By introducing its QR-DLT, Fantom connected medical products and items to their sophisticated databases in real time. Fantom can also connect physical documents to the network in real-time. Fantom use cases have saved lives by authenticating the distribution chain of medicine. Fantom can keep track of consumer behavior and distribution tracking and add an impenetrable security layer for the whole process. With fUNI, Fantom’s proprietary decentralized exchange that utilizes AMM instead of order books. Fantom can also operate as an efficient, slightly better version of Uniswap. Is Fantom a good investment? Fantom has a surpassed $385 million market cap with a trading volume of $65.6 million, priced at $0.15 per FTM at the time of writing. Considering the numerous use-cases Fantom has to offer and the features it is built on, Fantom is undoubtedly a fantastic investment. It provides speed, security, and ample room for growth. Moreover, the coin is ranked in the top 100 coins, therefore making Fantom an excellent investment. https://coinmarketcap.com/currencies/fantom Conclusion The DeFi space is growing tremendously since its inception, and platforms like Fusion and Fantom are proving to be the catalyst in this ever-growing niche. As we have discussed, these platforms are more oriented towards solving some of the core problems, namely scalability, and interoperability. With these scalable, efficient, and interoperable platforms, the DeFi sector could achieve mass adoption and remove some of the core bottlenecks. The price and every growing upward trend are a strong indication that the audience is showing significant interest to encourage growth and adoption. A special thanks to Chookz !

Catalysing DeFi: Introduction to Fusion and Fantom

Data storage security is as important as ever, no matter what industry you are a part of. Unfortunately, too many businesses lack efficient and modern technologies that can keep their data safe. Data loss can be a major roadblock on the path to successful scaling and development. No matter the size of the company. In fact, data loss can be caused by quite a few different factors. From malware and viruses to power outages to accidental damage, data loss is much more common than you would think. Because of this, it's necessary to secure an enterprise's data. Luckily, there are a ton of options out there. Two popular options involve backup and snapshots. Both of these processes are used to reduce data loss scenarios by essentially "backing up" your data. However, they are both very different from one another and each boasts their own use cases. In this quick guide, we'll be breaking down snapshot vs back and their key differences. What is a Server/File Backup? A server backup (or file backup) is simply a copy of a system or server's files. When you create a backup, it essentially creates new copies of files that you choose or entire systems. These copies are kept in a different location than the original source, which makes them quiet dependable in the case of file corruption or data loss. The main difference between a backup and a snapshot is that backups are isolated copies of data. They aren't connected to your virtual machine. That means that they can offer an entire virtual machine copy, so a partial disk failure won't result in substantial data loss. Backups can be easily moved to the cloud or an off-site data center, unlike snapshots. The Pros of Server Backups If you upload backups to the cloud, they can be accessed from anywhere at any time. They can easily be moved to the cloud, an off-site location, or a data center. Server backups are highly efficient, reliable, and ideal for long-term data center protection. They are an excellent choice for disaster recovery. Server backups do not require both on-site and off-site storage. The Cons of Server Backups The backup process can take days to complete, depending on the volume of data you are backing up. When to Use Server Backups Ideally, server or file backups should be used if you want to invest in long-term data protection. If you're willing to wait on potentially long backup times, then server backups are a great option to consider. Backups aren't just ideal for business continuity. They can also provide features that snapshots simply cannot. Think of image-level backups. They offer a slew of recovery options and can recover entire virtual machines or applications. For less dire scenarios, you can use in order to only back up the data that has changed recently, so you can save up on storage space. incremental backups What is a Snapshot? A snapshot is a quick "photo" of your server's file system for a specific period. This photo of your file system is typically used to restore entire servers in the event of data loss or corruption. Usually, when there is no longer enough space, new snapshots will overwrite older snapshots. Snapshots can be quite useful in some scenarios. The Pros of Snapshots Snapshots are small and can be made quickly and easily without too much of an effect on the server. They allow for better app availability, quick recovery, simplified backup management of big data volumes, and reduce exposure to data loss. Snapshots can be scheduled and used when necessary for system backup. They can nearly eliminate the need for backup windows and lower the cost of ownership. Data that is corrupted or has been deleted can be brought back through snapshots. (Just as well, you can revert back to an older version of a snapshot in the event of file corruption. Rather than restoring a whole system, one can switch to replicated snapshot copies since they are already in their native format. You can restore a server from a snapshot instantaneously. The Cons of Snapshots Snapshots can run out of storage space and backups will cease. Snapshot backups rely on the system's source database and have to be on the same server. If a server has too many snapshots, the system will slow down product volume. It's worth noting that this only happens through copy-on-write snapshot data. Most snapshot systems have negligible lag. If the server becomes corrupted, it is vital to create a whole additional snapshot backup. This means that both onsite and offsite backups will have to be used to ensure fail-proof data recovery. This, of course, can be quite expensive. When to Use Snapshots When thought snapshot backup has its downfalls, the advantages are quite good. It's a very practical solution for system backup if it's used with both on-site and off-site backup systems. If your startup or enterprise already has these storage systems in place, snapshots can be a great solution to data backup and security. However, they are best used for short-term situations. Summary: What are the Key Differences Between Snapshots and Backups? A backup is a duplicate of a file or any type of data. Once a backup is initiated, it will copy your files. These copies are kept in a separate location. Backup processes can take quite a long time to complete, depending on the volume of data you are backing up. Snapshots are an immediate sort of "photo" of your server's file system. This photo captures everything about the server exactly when it was taken. Snapshots can be used to restore servers by reverting them to the state they were in when the snapshot was taken. To summarize, here are the main differences between a server/file backup and snapshots: Backups can be stored in additional locations, the same drive, or even the same server. They do not require off-site and on-site storage. Snapshots require both on-site and off-site storage and must always be stored in the same places where the original system data is located. For SQL servers, backups are usually taken via a paid service. For snapshots, the processes involved are usually free and can be generated at any time. Backups can have differences between when the backup began and ended. Snapshots are "photos" of your server that preserve it exactly as it was at a given time. The process of creating backups can be long and tedious. Snapshots are instantaneous and take a lot less time to complete. Snapshots take less time to copy data as well. Backup files only include the file system. Snapshots can be made of different types of systems. These include files, apps, settings, etc. Backups exist in different specific locations and can easily be restored. Backups are also usually verifiable. Snapshots are not exactly backups. They can be used as part of the backup process (and should be) but are mostly short-term solutions. Snapshots are deleted when a backup is complete. Both snapshots and backups have their own pros and cons. However, it's generally recommended to opt for backups if you need long-term coverage. Snapshots are designed for short-term use and storage. They are generally only useful if you need to revert to a very recent version of your server on the same infrastructure. When it comes down to it, both snapshots and file backups can be used together for different levels of data protection, and in fact, this is the most recommended setup for a bullet-proof backup strategy.

In this post, we will see how to use different visualizations, like the simple graph, pie chart, or world map panel in the Grafana dashboard. We'll do this by writing queries in the Influx query language and fetching data from the InfluxDB database which is a time-series database. a. Data Visualization b. Installing Plugins Docker Grafana c. Writing to the InfluxDB2.0 LINE CHARTS: 1. As we can see, we are showing the records for 2 different blocks, i.e, DS_Id = 0 and DS_Id = 1.The timestamp is the same for both the blocks, 1598918400, 1598918402, 1598918403. The date for the above can be obtained from the link: https://www.epochconverter.com/ TIMESTAMP	DS_Id	POWER_A	POWER_B	POWER_C 1598918400 0 1403.421 712.372 1680.471 1598918402 0 1423.817 731.249 1680.658 1598918403 0 1444.172 749.339 1700.859 1598918404 0 1774.402 1106.427 2041.954 1598918405 0 1774.402 1106.427 2041.954 TIMESTAMP	DS_Id	POWER_A	POWER_B	POWER_C 1598918400 1 821.847 574.748 1203.807 1598918402 1 823.367 574.315 1203.795 1598918403 1 819.939 574.261 1203.647 1598918404 1 819.939 574.261 1203.647 Our requirement is to get the aggregated power for POWER_A, POWER_B, POWER_C fields. For example, for the timestamp 1598918400: TIMESTAMP	DS_Id	POWER_A	POWER_B	POWER_C 1598918400 0 1403.421 712.372 1680.471 1598918400 1 821.847 574.748 1203.807 We have values for POWER_A as 1403.421W and 821.847W, sum as 2225.268W. Likewise, we have to calculate for all the time-series values(1598918402, 1598918403, 1598918404, …) for POWER_A, POWER_B and POWER_C also. This computation is done in Grafana. We are implementing this using the SQL syntax like queries as shown below: We are going to compute the aggregated power for the field POWER_A now. All the queries were constructed and executed successfully by . Narendra Reddy Mallidi, SQL Developer We have our first query below: POWER_A AA = SELECT as FROM "hdb2" WHERE "DS_ID" '0' Here, POWER_A is the variable where are going to fetch from the table(table is called measurement in InfluxDB queries) named "hdb2". The same thing is followed for other 4 blocks also(DS_ID =’1’, DS_ID=’2’, DS_ID=’3’, DS_ID=’4’) POWER_A BB = POWER_A CC = POWER_A DD = POWER_A EE = SELECT as FROM "hdb2" WHERE "DS_ID" '1' SELECT as FROM "hdb2" WHERE "DS_ID" '2' SELECT as FROM "hdb2" WHERE "DS_ID" '3' SELECT as FROM "hdb2" WHERE "DS_ID" '4' Now, we compute the aggregated power for POWER_A with the below query: SELECT sum(ds1) + sum(ds0) + sum(ds2) + sum(ds3) + sum(ds4) AS Total
FROM
(
SELECT POWER_A ds0 FROM WHERE = ),
(
SELECT POWER_A ds1 FROM WHERE = ),
(
SELECT POWER_A ds2 FROM WHERE = ),
(
SELECT POWER_A ds3 FROM WHERE = ),

How to Use Different Data Visualizations in the Grafana Dashboard

How to name your extension? Firefox has a limit of 50 characters on the add-on title but Chrome allows a bit more than that. To be able to use the same manifest.json file, stick to 50 characters with the name. If you are not an established brand then no one is going to find you just by your product name. Focus on your Unique Selling Proposition (USP) and the keywords for which you want to rank in the Web store and use them in your extension name. For example, we use "Bookmark manager, URL Shortener, Text highlighter" keywords in our and title instead of because mostly the potential users are looking for a feature and not a product Chrome extension Firefox add-on linkish How to use the same namespace everywhere? Since there are no common standards, browsers are using multiple instances like and of the same object. The easiest way to set up that is by adding this snippet on top of your background and content-script files. chrome browser window.browser = (function () { return window.msBrowser || window.browser || window.chrome; })(); This will ensure that the entire extension can be ported from Chrome to Firefox without checking each file for possible errors. We will now use the namespace which will work for both Chrome extension and Firefox add-on browser ❌ Avoid this var sending = chrome.runtime.sendMessage() ✔️ Do this var sending = browser.runtime.sendMessage() How to find your current browser's environment? Since both Firefox and Chrome support and , we can not use them to determine that, but as each extension has its own page in the browser, it has its own unique URL as well which can be accessed like: chrome browser const extURL = browser.runtime.getURL(""); const isFirefox = extURL.startsWith("moz-extension://"); const isChrome = extURL.startsWith("chrome-extension://"); These can be used to keep browser-specific logic and requirements that we will discuss next week. What graphics do I need for my extension? There are three types of graphics required in your extension, namely logo/icon, screenshots, and promo tiles. Here are the specific requirements for those graphics: - 16x16 : Suggested by Chrome - 48x48 : Required by Firefox and Suggested by Chrome - 96x96 : Suggested by Firefox - 128x128 : Required by Chrome Logo / Icon - Up to a maximum of 5 (at least one is required ) - 1280x800 or 640x400 - JPEG or PNG (no alpha) Screenshots - Small promo tile : 440x280 Canvas, JPEG or PNG (no alpha) - Large promo tile : 920x680 Canvas, JPEG or PNG (no alpha) - Marquee promo tile : 1400x560 Canvas, JPEG or PNG (no alpha) Promo tiles ( only for Chrome ) Small promo tile, although optional, is very important for a Chrome extension as in its absence, your icon will be shown in the Chrome search results which alone does not look trustworthy. I hope this post will help you create one extension that you can upload to all the extension stores sometime soon.

A Guide to Creating True Cross-Browser Extensions

Yield farming can be highly lucrative, but also very risky. The level of impermanent loss can discourage some users. Even with the heightened enthusiasm, the potential for waiting out impermanent loss or aggressive arbitrage is a risk that not all crypto owners are ready to take. The right tokenomics model, however, can work to create a more stable distribution of wealth. Yield farming is the faster, riskier version of staking. But the concept of passive income may add to the appeal of tokens intended to be included in liquidity pools. We looked at several projects with outstanding tokenomics, which try to achieve better stability while also giving opportunities for yield farming. Currently, multiple projects are attaching themselves to major algorithmic market-making platforms like Uniswap. But some token-based projects will attempt to differentiate from the multitude of assets created with the sole purpose of simple yield farming. Wanchain DeFi was one of the older tokens, powered by an ICO fundraiser in late 2017. The WAN market price was severely affected by the hype and crash of late 2017, and went on to lose more than 90% of its value. Wanchain However, the token had gained footing and was traded on traditional exchanges, as well as having a community of holders. WAN then pivoted to become one of the up-and-coming yield farming tokens. Wanchain was already a project committed to open finance. Its initial goal was to connect public and private various blockchains. Its foray into yield farming, however, uses the Ethereum ecosystem, where already enough liquidity allows for fast price discovery. The WAN token was also initially built with staking rewards, node, and transaction fees, making it a potential source of passive income. Wanchain, through its WanSwap app, plans to combine the project’s cross-chain capabilities with liquidity pools. Thus, WAN liquidity could be derived from multiple chains wrapping funds on Wanchain, including BTC. Additionally, a new WASP token will be created to add rewards for liquidity providers. RFIII Compound Liquidity is another new arrival on the DeFi scene. Like other similar projects, its chief attraction is both the potential for high returns through yield farming, but also a regular redistribution of profits. Holding and staking the RFIII token itself carries passive rewards, including a portion of trading fees. RFIII Compound Liquidity The approach of RFIII is to create several avenues for passive income. The token itself will not need separate technology for staking. Simply depositing the tokens will trigger the smart contract, which will ensure both liquidity and trading fee redistribution. Each trade on the RFIII network will bring a 1% fee which will be distributed to all token holders. The chief utility of RFIII tokens would be a tool for storing value, as a form of treasury. Converting ETH to RFIII will give owners right to hold the token and potentially reap rewards for years to come. World Token.network is yet another attempt to build a global, borderless economic system with no barriers to entry except token ownership. World Token World Token relies on Uniswap pairings, but it also aims to build frictionless tokenomics, where liquidity providers also receive staking rewards with no extra steps needed. The reward system hinges on a 3% transaction tax, which is redistributed to all network participants. The 3% tax aims to finance several sides of the World Token system. 1% goes toward marketing expenses, another 1% is sent to the Uniswap liquidity pool, and another 1% is shared among regular holders of the WORLD tokens. World Token aims to differentiate itself from new assets launched just for the sake of creating liquidity pools. The project will aim to partner with some of the biggest DeFi projects for achieving wider distribution and multiple pools. Additionally, WORLD will be used within a crypto-powered marketplace. The launch of the World Token decentralized store program is scheduled for the second quarter of 2021. World Token will also continue growing as a marketplace, ensuring utility for its native token. The marketplace will expand to physical items, add an escrow service and a dispute system. The final stage of the project is to build a P2P swap and exchange platform. Reflector.Finance is another project highly active at the start of 2021. Once again inspired by the problems of rug pulls, high fees and impermanent loss, the project has taken the path of frictionless yield farming. Reflector Finance The distinguishing point of RFCTR is the extremely high transaction tax, as high as 12% redistributed to token holders. As with other tokens, RFCTR uses the Uniswap algorithmic market making. The high transaction tax has a twofold purpose - one, it serves as a mining fee, because the token does not rely on mining. And second, it is an incentive to offset the potential impermanent loss from providing Uniswap liquidity. The third element that ensures gains with the Reflector Finance protocol is a regular token burn, which constrains the supply and creates a deflationary ecosystem. With those elements, Reflector also joins the trend of creating a tokenomics equation engineered to generate income over time and serve as an incentive to hold onto the tokens. The token burn for Reflector Finance is technologically achieved through a vault known as the Black Hole. This contract holds about 5% of all tokens and continues to receive some of the rewards, essentially locking them in and decreasing the total supply. Frictionless yield farming solves several issues that plagued small-scale crypto owners. One of the issues is the difficulty and expense of moving Ethereum-based tokens. Using one smart contract to ensure both yield farming and passive returns saves the hassle of having to move tokens for staking. It is also a solution to the problem of having tokens locked on exchanges, where sometimes receiving staking rewards is made more difficult. The early days of yield farming saw multiple projects fizzle out within days. Tokens generated high-level liquidity in their automated market-making pairs, but then the holders had the incentive to move on and search for better yields. It was this extreme volatility and crashed projects like Hotdog that made some projects reconsider their tokenomics. For a sustainable project that aims to unite a worldwide community, it is not enough to achieve a very short, rapid price appreciation, followed by a crash. The new trend of combining passive income with yield farming is already helping older token-based projects to revive their stagnant prices. Multiple altcoins are going through another appreciation cycle based on both widespread ownership from the past, and new offers for income from algorithmic market making.

Passive Income and Yield Farming: A New Trend for 2021

If you care just a slightly bit about the stock market ( ), you probably know that on 02/11, Tinder-rival Bumble made its debut on NASDAQ under the ticker symbol ‘BMBL’. It was initially priced at $43 per share, and by the end of the first trading day, the stock soared to $70.31 apiece (you do the math, that’s a 63.5% rise). and maybe, dating apps The stock closed at $71.75 per share on the trading day of 02/19, marking the market cap at $8.28B. Bumble's stock price (Resource: Google ) There was a lot of buzz around the company. We know that Bumble’s Founder and CEO, Whitney Wolfe Herd, was indeed the former co-founder of Tinder (the tea!) We know that they had a much-talked about in 2018. We also know that at 31, Herd is to lead an IPO. lawsuit the youngest female executive So, back to business. What is the deal with Bumble? But first, what is Bumble? For those who don’t know, Bumble is essentially a location-based dating app: you log in, browse profiles of people in your area, then swipe right if interested, or swipe left for Thank U, Next. If both individuals swipe right, it’s a match. There is a twist: after the right swipe, , and the match goes away if no message is sent after the first 24 hours. That gives the women their control of the conversation, and saves users from the exasperation of a 6-month match without a move. only the woman can send the first message While Bumble is free to use, you can pay an extra fee for advanced features. We have Boost, starting at $12.99 per week, where you can unlock options like Rematch, SuperSwipe, or Spotlight. Or, if you are feeling fancy, you can pay $17.99 per week for the Premium, where you get even more features like Travel (match with people from other cities) or Beeline (see all the singles who like you). real Bumble also offers BFF mode for platonic relationships, Bizz mode for professional networks, and Badoo - its sister app in Europe and Latin America. Bumble's IPO (Resource: @bumble ) Why Is It a Big Deal? Impressive Performance with Opportunities to Grow Now, let’s talk . numbers These figures below reflect the financial indicators of Bumble Holdings from its Bumble and Badoo apps. Figure 1: Bumble’s Financial Indicators 2018-2019 (Resource: SEC.gov ) Figure 2: Bumble’s Financial Indicators 9/2019 - 9/2020 (Resource: SEC.gov ) Pre-COVID, Bumble saw a lucrative revenue of $488.9M - a YOY growth of 35.8%. This is impressive compared to the YOY increase of 11.59% by Match Group ( ). In 2019, Bumble also enjoyed a net earnings YOY growth of 17.6% and net cash provided by operating activities of 41.2%. resource: MacroTrends In 2020, the company posted less-impressive revenue growth of 15% with a net loss of $84.1M. This was attributed to the impact of COVID-19 and the company’s increasing costs. However, this shouldn’t be a factor to predict Bumble’s financial performance in the next few years, considering the high volatility of the market. We will need to wait for its reports in the coming quarters to be able to observe the performance and use of money flow from the public offering to weigh the performance. Even with the slowdown in revenue and negative profitability, Bumble managed to grow its usage by 25% and steadily increase its market present in the U.S. dating app market, and almost doubled in market share in 2020 from 2017: Figure 3: U.S. Dating App Market Share by Revenue (Resource: SensorTower ) The real potential growth for Bumble lies in its international market, where it now occupies 2% of market share (the big guys are Badoo and Tinder, but Badoo has been declining for the past 5 years). OC&C projects that in North America alone, the online dating scene will grow 11% annually to a $3.4B market in 2025. The global market will see an annual growth of ~13% to 981M singles having access to the interweb and a $9.9B market in 2025 ( ). It is without question that Bumble will enjoy the benefits of scale in the years to come. resource: SEC.gov Strong Brand Presence In the Company’s introduction, Founder and CEO Whitney Wolfe Herd writes: S-1 Our users connect deeply with our brand, making it a powerful marketing tool which generates word of mouth virality and strong, efficient user acquisition. This is evidenced by the fact that only 22% of new users across our apps came from attributable performance marketing in the nine months ended September 30, 2020. Take a second to look bumble up on Instagram, you will see several accounts such as , , or (which is mad hilarious), each with a hundred million followers; not to mention the hashtag #bumble with more than 400K related posts. With gen Z rising and living their life through social media, this Instagram influence is a real deal. @bumble @bumblebizz @overheardbumble (Resource: @overheardbumble ) The Bumble team makes extra efforts to connect with other organizations and give back to the community. For example, for Valentine’s Day Special, it for special virtual dating experiences. It also launched the Bumble Fund to . It also pushes market presence through programs like Bumble Honey, recruiting college students to be the ambassadors. teamed up with AirBnB invest in women founders With its continuous efforts to improve brand awareness, Bumble is now the second largest dating app in the U.S. with 5M users, and comes 4th on the global scale ( ). resource: Business of Apps The Powerful Whys: Bumble's Mission to Create a Safe Space It is undeniable that even though we are in 2021, discrimination against women in both their and romantic life still exists. Being the women-first dating app, Bumble works to address the situation. professional “The Bumble brand was built with women at the center—where women make the first move. We are rewriting the script on gender norms by building a platform that is designed to be safe and empowering for women, and, in turn, provides a better environment for everyone.” Whitney Wolfe Herd, Bumble SEC S-1 Bumble claims to create a safe and equitable environment for the users. For instance, in 2019, they introduced that blurs nude images automatically, leaving users’ the decision whether to see it or not. a new feature Challenges Ahead Industry Competition and User Base Flux The booming online dating market can be a double-edged sword to Bumble. The most prominent competitor is Match (Tinder’s parent), who is close to monopolizing the space, with a wide-ranged portfolio of 45 businesses in total. And the rival is not just Tinder. In Figure 3 above, we can see that Hinge expanded rapidly from less than 1% in the U.S. market (2017) to 6% in 2020. Not to mention other apps like , , , by which Match caters to users of all backgrounds. Match SingleParentMeet SeniorPeopleMeet A glance at Match Group’s portfolio (Resource: The Motley Fool ) Even Herd admits that the dating app market is not a winner-takes-all situation, “ ”. With dating apps now operating on a freemium basis, the cost of switching apps for users is minimal, which leads to potential user base fluctuations. with people using or having an average or two different apps installed on their phone at the same time There are a number of risks associated with the user base for any app, and Bumble is not an exception. Users can engage less in Bumble, which leads to a potential decline in in-app purchases. Users can also find preference in competitive apps, which offer more in terms of features and product innovation. Or, users can find their significant other on Bumble and no longer see the need to use the services. The question is, while Match can rely on other revenue streams if Tinder goes south, what alternatives does Bumble Holdings have if Bumble falls short? Can Badoo take place with a declining performance? Will the company have enough time and resources to roll out other services to keep up in the game? The Role of BFF and Bizz Launched in 2016 and 2017 respectively, BFF and Bizz shows Bumble’s ambition to tap into the “non-romance” aspects of forming a relationship, both platonic and professional. The question is, how much of an impact is there? Bumble BFF sounds like an exciting platform for young people (*cough* gen Z *cough*) to make new friends especially in a new city or in this pandemic we are living in. However, its similarity to Bumble Date is questionable. Would you really decide to be friends with an individual based on a minimum of 4 photos and an excerpt of their life (some won’t even fill it in)? not What would you do when all you want is to make new friends in your new place, but some think that you’re not cool enough for a conversation? It seems like Bumble hasn’t quite reached its goals to convert the traditional way to form a friendship, at least . from what I gather The professional platform, Bumble Bizz, can be an addition to the networking book; however, it is not the ultimate networking site. Do you want to swipe hours to find a potential business match who may or may not be interested in the same field as you are? If you want to network with other people based on professionals and locations, LinkedIn seems like a much more optimal solution. Don’t get me wrong here. If by any chance, you’re reading this story and happen to have a very good experience on either platform, I’m very happy for you. Yet, I believe these two leave a lot to be desired in order to stand out from the crowd. Furthermore, since there is no record of BFF and Bizz generating revenue for Bumble, their role is almost oblivious to potential investors. Conclusion At the end of the day, it depends on the investor to decide whether BMBL is their perfect match. Do you see Bumble as a portfolio maker in the future, providing its steady increase in market presence and high potential of dominating the market? Are you moved by its mission and core value? Or are you still reluctant, waiting to see the public balance sheets in 2021 before making an investment decision? As for me, I am excited about Bumble's earning calls, where I have a more thorough understanding of its financial health and efficiency, after raising $2.51B from the IPO.

What is Threat Modeling? While there is not one exact industry-wide definition, Threat Modeling can be summarized as a practice to proactively analyze the cybersecurity posture of a system or system of systems. Threat Modeling can be conducted both in the design/development phases and for live system environments. It is often referred to as Designing for Security. In short, Threat Modeling answers questions such as “Where am I most vulnerable to attacks?”, “What are the key risks?”, and “What should I do to reduce these risks?”. More specifically, Threat Modeling identifies cybersecurity threats and vulnerabilities and provides insights into the security posture, and what controls or defenses should be in place given the nature of the system, the high-value assets to be protected, the potential attackers’ profiles, the potential attack vectors, and the potential attack paths to the high-value assets. Threat Modeling can consist of the following steps: 1. Create a representation of the environment to be analyzed 2. Identify the high-value assets, the threat actors, and articulate risk tolerance 3. Analyze the system environment from potential attackers’ perspective: How can attackers reach and compromise my high-value assets? I.e. what are the possible attack paths for how attackers can reach and compromise my high-value assets? What of these paths are easier and harder for attackers? What is my cyber posture — how hard is it for attackers to reach and compromise my high-value assets? If the security is too weak/risks are too high, 4. Identify potential measures to improve security to acceptable/target levels 5. Identify the potential measures that should be implemented — the most efficient ways for your organization to reach acceptable/target risk levels Why Threat Model — The Business Values Threat Modeling is a very effective way to make informed decisions when managing and improving your cybersecurity posture. It can be argued that Threat Modeling, when done well, can be the very most effective way of managing and improving your cyber risk posture, as it can enable you to identify and quantify risks proactively and holistically and steer your security measures to where they create the best value. Identify and manage vulnerabilities and risks before they are implemented and exploited Before implementation: Threat Modeling enables companies to “shift left” and identify and mitigate security risks already in the planning/ design/ development phases, which is multiples — often 10x, 100x, or even more — times more cost-effective than fixing them in the production phase. Before exploited: As rational and effective cyber defenders we need both proactive and reactive cyber capabilities. Strengthening security proactively, before attacks happen, has clear advantages. However, it also comes with a cost. An effective Threat Modeling enables the user to make risk-based decisions on what measures to implement proactively. Prioritize security resources to where they create the best value One of the very key challenges in managing cybersecurity is to determine how to prioritize and allocate scarce resources to manage risks with the best effect per dollar spent. The process for Threat Modeling, presented in the first section of this text, is a process for determining exactly this. When done effectively, it takes into consideration all the key parts guiding rational decision-making. There are several additional benefits to threat modeling. One is that all the analyses are conducted on a model representation of your environment, which creates significant advantages as the analyses are Also, analyzers can before implementations. non-intrusive. test scenarios Another set of values are that threat models create a in your organization and . To keep this text concise, we here primarily highlight the values above. We also want to state that there are several other excellent descriptions of the values of threat modeling, and we encourage you to explore them. common ground for communication increase cybersecurity awareness Who does Threat Modeling and When? On the question “Who should threat model?” the says “You. Everyone. Anyone who is concerned about the privacy, safety, and security of their system.” While we do agree with this principle in the long term, we want to nuance the view and highlight the need for automation. Threat Modeling Manifesto Threat Modeling in development: This is the ”base case” for Threat Modeling. Threat modeling is typically conducted from the design phase and onward in the development process. It is rational and common to do it more thoroughly for high criticality systems and less thoroughly for low criticality systems. Threat modeling work is typically done by a combination of development/DevOps teams and the security organization. More mature organizations typically have more of the work done by the development/DevOps teams and the less mature organizations have more work support from the security organization. Threat Modeling of live environments: Many organizations also do threat modeling on their live environments. Especially for high criticality systems. As with the Threat Modeling in development, organizations have organized the work in different ways. Here, the work is typically done by a combination of operations/DevOps teams and security organization. Naturally, it is advantageous when Threat Models fit together and evolves over time from development through operations and DevOps cycles.

In the of this , we already learned how to write Wasm modules in AssemblyScript. In this part, we will use this knowledge in a practical scenario: image manipulations with WebAssembly. previous part series We will demonstrate a typical use-case by a simple function for converting an image to . grayscale Albeit the calculation of the gray color is not very demanding, it clearly demonstrates the real-world usage of WebAssembly on the web: . computation-intensive tasks You can find the full discussed source code on . my GitHub Browser Runtime Unlike our previous experiments with AssemblyScript, this time we will run our Wasm module in a browser. You might first recall how to use a , but the code is quite straight-forward: web browser as a Wasm runtime WebAssembly
  .instantiateStreaming(fetch( ), {})
  .then( {
    ...
  } 'grayscale.wasm' ( ) => { instance } To make the work you must serve the web page via HTTP(S). Fetch API The second argument of the is an object with Wasm imports. All environment imports for Wasm modules, which were compiled from AssemblyScript, are included in an object: instantiateStreaming env When running in the browser, we must import an error-callback function : abort WebAssembly
  .instantiateStreaming(fetch( ), { : { : .error( )
    } 
  }) 'grayscale.wasm' env abort ( ) => _msg, _file, line, column console `Error at : ` ${line} ${column} In Node.js those are already provided by the AssemblyScript loader out of the box. Canvas To show the image and its transformation in a browser, we will use the HTML : canvas element < = = = > canvas id "canvas" width "500" height "500" </ > canvas And its 2D context: canvas = .getElementById( ); ctx = canvas.getContext( ); [width, height] = [canvas.width, canvas.height]; const document 'canvas' const '2d' const First, we will draw the original image on the canvas: img = Image();
img.src = ;
img.crossOrigin = ;
img.onload = ctx.drawImage(img, , , width, height); const new './my-pretty-picture.png' 'anonymous' => () 0 0 Then, we will get the that we will work with: image data imageData = ctx.getImageData( , , width, height); data = imageData.data; const 0 0 const The image is represented as a a one-dimensional array in the RGBA order, with integer values between 0 and 255 (inclusive). data Uint8ClampedArray Memory Because we will work extensively with memory, we should . recall the fundamentals We can either create a memory instance from JavaScript and import it into the Wasm module or let the module initialize memory and export its instance into JavaScript. One benefit of the former approach is the possibility of initializing memory to the needed size. When exporting memory from Wasm, the initial size is one (64 KB). To increase its size, we have to call programmatically, which could be impractical, at least in cases where the size is known in advance. page memory.grow() Our image might be bigger than 64 KB, so we had better create a big-enough memory instance: arraySize = (width * height * ) >>> ; nPages = ((arraySize + ) & ~ ) >>> ; memory = WebAssembly.Memory({ : nPages }); const 4 0 const 0xffff 0xffff 16 const new initial Here comes the catch. To be able to import memory into a Wasm module, we have to compile our AssemblyScript code with the flag: --importMemory $ npm run asbuild:optimized -- --importMemory This will generate the following line in the compiled Wasm module: ( ( $ )) import "env" "memory" memory 0 1 Now, we can import our memory object from JavaScript into Wasm: WebAssembly
  .instantiateStreaming(fetch( ), { :{ memory }
  }) 'grayscale.wasm' env The next step is to initialize the memory with the image data: bytes = (memory.buffer); ( i = ; i < data.length; i++)
  bytes[i] = data[i]; const new Uint8ClampedArray for let 0 As you might have noticed, we use the same — — as image data to format and access memory bytes. typed array Uint8ClampedArray When the memory bytes are filled, we can execute our Wasm function: instance.exports
  .convertToGrayscale(width, height); And store the result from memory back into the image: ( i = ; i < bytes.length; i++)
  data[i] = bytes[i];
 
ctx.putImageData(imageData, , ); for let 0 0 0 Image Manipulation Now, when we have all we need to run an image-manipulation function in a browser, we shall actually write one. As previously mentioned, we will create a function that converts an image to grayscale: { len = width * height * ; ( i = ; i < len; i += ) { r = load<u8>(i); g = load<u8>(i + ); b = load<u8>(i + ); gray = u8(
      r * + g * + b * );
 
    store<u8>(i,     gray);
    store<u8>(i + , gray);
    store<u8>(i + , gray);
  }
} export ( ): function convertToGrayscale width: i32, height: i32 void const 4 for let 0 4 /*rgba*/ const const 1 const 2 const 0.2126 0.7152 0.0722 1 2 As the image data contains linear RGBA quadruples of 8-bit signed integers (clamped to the range of values from 0 to 255), we iterate the array of data in 4-incremental steps. We load the RGB values from memory, compute the gray color, and store the color values back into the memory. Demo Time That’s it! Now we have all the know-how needed to develop awesome image processing Wasm functions in AssemblyScript. Here are some more examples: You can see demos . live on my blog The source code is on . my GitHub Previously published at https://blog.ttulka.com/learning-webassembly-10-image-processing-in-assemblyscript

Introduction Struggling with connecting and maintaining your microservices in Kubernetes? As the number of microservices grows, the difficulty and complexity of maintaining your distributed fleet of services grows exponentially. Messaging can provide a clean solution to this issue, but legacy message queues come with their own set of problems. In this article, I’ll share the benefits of messaging in Kubernetes and the difficulties that can come with legacy solutions. I'll also briefly look at one solution to this problem - KubeMQ - which attempts to address some of the traditional problems with messaging in Kubernetes. Why Messaging in Kubernetes? As a microservice-based architecture grows, it can be difficult to connect each of these distributed services. Issues of security, availability, and latency have to be addressed for each point-to-point interaction. Furthermore, as the number of services increases, the number of potential connections also grows. For example, consider an environment with only three services. These three services have a total of three potential connections: However, as that increases to say five services, the number of potential connections increases to 10: With 20 services, the number of potential connections is 190! For reference, see the table below: This is clearly not sustainable for organizations with a large portfolio of services. However, through the use of a message queue, we can centralize those connections. Since the number of connections is equal to the number of services, this results in a solution which scales linearly. See below: For a large microservice fleet, this significantly simplifies the security and availability issues, as each microservice needs to communicate primarily with the message queue. This is the very reason implementing a message queue architecture is considered the best practice when running large numbers of microservices in Kubernetes. As a result, the selection of the message queue is a critically important decision, as the entire architecture will depend on the reliability and scalability of that message queue. Finally, deploying the message queue in Kubernetes allows you to avoid platform lock-in. There are a number of platform-specific messaging solutions from the major cloud providers, but running a platform-agnostic solution allows you to keep your microservices architecture consistent, regardless of your platform. Kubernetes is the de facto orchestration solution and has support from all major cloud providers. Now that we’ve established why messaging is helpful, let’s dig a little deeper. This seems like such a simple solution, so what could be so hard about it? What's hard about messaging in Kubernetes? There are a number of pain points when attempting to run a message queue in Kubernetes. Let’s consider the differences between a typical microservice and your standard message queue. I’ve summarized some of the differences in the following table: First, microservices are designed to be resource-light. This is in some ways a natural result of being a microservice — each service performs a single purpose, and thus can be smaller and more nimble. In contrast, legacy message queues are large, resource-intensive applications. The latest version of IBM MQ at the time of writing has . For example, > 1.5 GB disk space and 3 GB of RAM. significant hardware requirements Additionally, a typical microservice is stateless, as it does not contain any part of the state of the application in itself. However, many legacy message queues function effectively as databases and require persistent storage. Persistent storage in Kubernetes is best handled with the , but this requires workarounds for legacy solutions. Persistent Volume API These differences in resource usage lead naturally to the next point—microservices are simple to deploy. Microservices are designed to deploy quickly and as part of a cluster. On the other hand, due to their resource-intensive nature, legacy message queues have complex deployment instructions and require a dedicated team to set up and maintain. Next, microservices are designed to be horizontally scalable. Horizontal scaling is done through the deployment of additional instances of a service. This allows a service to scale nearly infinitely, have high availability, and is generally cheaper. In contrast, due to the aforementioned resource requirements and deployment pains, legacy message queues must be scaled vertically--in other words, a bigger machine. In addition to the physical limitations (a single machine can only be so powerful), larger machines are expensive. These issues typically require significant investment and time to resolve, reducing the value that the message queue provides to your overall architecture. However, none of these issues are inherent to messaging; they are instead an artifact of when the major message queues were designed and conceived. So how can we address these issues? Let’s take a look at one option: using a Kubernetes-native message queue such as KubeMQ. A Kubernetes-native Approach is one way of solving Kubernetes-related messaging issues. Let’s take a look at a few ways it does this. KubeMQ First, it is , which means that it integrates well with Kubernetes and is simple to deploy as a Kubernetes cluster. that allow you to automate tasks beyond what Kubernetes natively provides come with the product for lifecycle management. is supported through both local volume and PVCs. Being Kubernetes-native also means that it is cloud-agnostic, and thus it can also be deployed on-premises or into hybrid cloud environments. Kubernetes-native Operators Cluster persistency Additionally, it is —the Docker container is roughly ~30 MB, a far cry from the GB of required space from legacy solutions. This allows it to be deployed virtually anywhere and enables new use cases, such as edge deployments for Internet-of-Things device support. Despite its small size, it has support for a variety of messaging patterns. lightweight Finally, it is . Through the use of Bridges, Targets, and Sources, these pre-built connectors allow it to connect to a variety of other applications and services, reducing the need for custom integrations. Bridges allow KubeMQ clusters to pass messages between one another, enabling KubeMQ to connect various cloud, on-premises, and edge environments. extensible Since KubeMQ is small, you can try it out for yourself with a or access to any other Kubernetes cluster. local installation of minikube for a (free) account and get a license token. Sign up Run kubectl apply -f =<your-license-token> https://get.kubemq.io/deploy?token You can verify the status of your cluster with kubectl get kubemqclusters -n kubemq. For more information, check out the . official docs Summary In this article, I reviewed the benefits of a message queue, looked at difficulties around implementing messaging in Kubernetes, and took a quick look at —a lightweight and Kubernetes-native solution that can provide several advantages over legacy solutions.

An Introduction to Microservice Messaging in Kubernetes

The internet is not one size fits all. Browser extensions make it work well for different people and are ubiquitous on desktop browsers. But the mobile browser has never enjoyed extensibility in the same way, even though we now spend more time on it than desktop. [1] The iPhone was the first phone to be able to have a full web browser back in 2007. But iOS Safari never became extensible. Some mobile browsers come bundled with ad-blocking, and there is a limited way to do extensions in Safari. Why do we need an extensible iOS browser? There are those of us who grew up on desktop and miss extensions when we're on our phones. But more importantly, we now have a generation of users growing up with their phones being their primary device and not all these kids are having their brains rotted by mobile usage. Many are creating and remixing powerful, in-depth content. What constraints are unique to mobile? From a technical point of view, Apple has restricted what developers can do with WKWebView, so we can't have the exact same extensions as we do on desktop. For example, you can't run Javascript in background tabs. Many of these restrictions are sensible from a user experience point of view, and Apple made browsers as stable as they needed to be as a result of these restrictions. But restrictions aren't always bad. When I worked at Mozilla in 2010 around the time an early version of the format was being developed, and despite being a "restriction" on what browser extensions could do, the simplified spec actually made extensions much more stable and accessible to a larger pool of users. WebExtensions What do extensions do, really? The WebExtensions spec has been very stable for a while so we take it for granted on desktop. Moreover, we take it for granted that it cannot be replicated on mobile. But when you think of what extensions do , we surveyed existing extensions on the Chrome extensions store and realized that most of them fit one of these patterns: for the user Augment pages with useful content (coupons, privacy data, etc.) Cleans up pages by removing content (ads, trackers, distractions) Scrapers or developer tools Pattern #3 is particularly challenging to do on mobile and we think is best done with standalone apps, e.g. . Inspect How we reimagined extensions mobile-first We focused on augmenting and cleaning up pages to make browsing the internet a more pleasant experience for most people. This is the dominant use case for extensions when you analyze the downloads data. People take far less time to set up their mobile browsers, so it's important to be useful out of the box. Insight thus suggests extensions from its collection as you browse the web. Finally, we reimagined the interaction design to be mobile-first, incorporating easy swipe gestures as a first-class action. With this, we're able to bring browser extensions to phones in an intuitive, usable way and without sacrificing their power. With this, developers can do amazing things like make the , block sites from tracking you and read the news more efficiently than ever before. web more readable for people with ADD What's next It's early days for but our mission is ambitious — we want to rid the internet of bad ads, SEO and misinformation.

With the rise of mobile devices, low-cost or free chat, social messaging apps have gained in popularity. They are a cheaper alternative to operator-based text messaging via SMS. Today, many companies have a reasonable interest to create a messaging app. If you are one of them, you will get a lot of value from this guide. We will cover the following topics: Reasons to Create a Messaging App Popular Features in a Messaging App An Optimal Technology Stack for Messaging App Development Natural Language Processing Best Monetization Approaches to a Profitable Chat App Time to Create a Messaging App. Reasons to Create a Messaging App There are different reasons why investors want to create a messaging app. We have identified at least two of them: improve employee and customer communication, build a subtype of a global social networking platform. While you need different tools to accomplish these goals, there are some features that are common for all apps and we are going to dive into some of them. Before we do that, let's look at statistics. Let's have a look at the global messaging apps first. Here is data on business messaging apps. Such apps gained in popularity especially after COVID-19 and with the expansion of remote work. Popular Features in a Messaging App Now let's have a look at some must-have features of your messaging app. 1. Instant Messaging This is the basic feature you need to have for a messaging app. Apart from simple communication, your instant messaging feature should provide options for: a secret chat; delivery status (the participants can see whether the message is seen or received); unsend messages (the participant can unsend the message within a certain period of time); group chats; moderation (admin can ban or remove users). 2. File Exchange Users may like to exchange files, such as photos or texts. Allow your users to attach files that can replace the regular email. 3. Push Notifications Your users become instantly available via the push notification feature. 4. Voice and Video Messages This feature first appeared in WeChat in 2015 and spread to other chatting software. It is a more convenient way of communicating if the users don’t have the time to type long messages. 5. Voice and Video Calls Free voice and video calls are an attractive feature of messaging apps. If you are thinking of how to create a messaging app, keep in mind that free phone calls attract users. 6. Public Channels With public channels, your messaging app will become a marketing tool for many businesses and communities. Nowadays a lot of chatting applications have this feature to beat competitors and attract new users. An Optimal Technology Stack for Messaging App Development To build a messaging app, you will need: a server to store messages and send notifications; a client; and transportation between the two. The server can use the backend language plus the database, e.g. node + mongo. This option is cheaper. However, you need to configure all of the routes, database connections, models, and API responses. The backend service provides the database, routes, and responses. You just need to define the data. This may be expensive at scale. Finally, the transportation is composed of API calls which are singular calls that return information to the client. Web sockets are an integral part which are persistent channels that allow information to travel enabling real-time communication. There are clear advantages to working with the backend. The service does much of the work and it provides you simple ways for transportation. A backend service like Parse can save you lots of time. Here is the tech stack used by WhatsApp, WeChat, and Viber. Read More: How to Create a Messaging Application from Scratch Natural Language Processing Natural Language Processing (NLP) applications are everywhere nowadays. We will talk about and when talking about NLP. Let's see how the two are different. chatbots virtual assistants Chatbots are programmed to reply to preset questions. They cannot answer the question if responses are not programmed. On the other hand, Virtual Assistants have a much sophisticated interactive platform. Apart from understanding the language, they also understand the meaning. Therefore, they can perform highly complicated tasks. For example, virtual assistants can compare products or find the best product based on the given features. Chatbots only pick up certain words.  Virtual Assistants can handle conversations and have robust NLP capacities. These intelligent machines can help to solve up to 80% of queries. More complex questions are routed to human agents. Best Monetization Approaches for a Profitable Chat App In this section, we will talk about how to make a profitable chat app. We will cover three monetization approaches currently popular in the market. Advertising In-app advertising is a good way to make money from an app. However, it is not always a convenient way. Ads are often annoying for users. Alternatively, you can give an option to disconnect ads at a cost. Anyway, ads are a good source of revenue for global messaging apps.  For example, in 2019, Facebook generated about 98.5 percent of its global revenue from , and only around two percent came from payments and other fees. advertising You may also think about built-in ads. For example, Snapchat uses an ad tool called Snapchat Ad Manager. These are some 10 seconds long ads that appear in between friends' stories.

A Miniature Guide to Messaging App Development in 2021

In order to submit an app to the Google Play Store, you need to sign the apk no matter what development framework you're using. In this article, we'll learn how to sign an apk using Cordova. Before starting we will assume that we have previously made all the necessary Cordova installations and added an android platform for our project. Create a keystore file First, we'll need to create the keystore file which is basically a binary file that can hold a set of keys. To create this file you'll need to go to the root of your project and run the command below: keytool -genkey -v -keystore myapp.keystore - myappalias -validity 10000 alias The tag stands for the expiration of the key. After running this command you will see the file at the root of your project. validity myapp.keystore Create a build.json file The file also needs to be created at root level and this is the place where we will store all the parameters needed for signing. The file needs to look something like this: build.json { : { : { : , : , : , : , : }, : { : , : , : , : , : }
    }
} "android" "debug" "keystore" "./myapp.keystore" "storePassword" "pass" "alias" "myappalias" "password" "pass" "keystoreType" "jks" "release" "keystore" "/myapp.keystore" "storePassword" "pass" "alias" "myappalias" "password" "pass" "keystoreType" "jks" Set version and package name Next, we need to do is open the file at root level where we can set the version, version code, and package name in the tag at the top of the file. config.xml widget < = = = = > widget android-versionCode "10" defaultlocale "en-US" id "com.example.myapp" version "1.0" ... is used only for calculations by Google Play and is not visible for users versionCode is the package name of your app id is the version of your app that will be visible on Google Play version Building the app The last thing that we want to do is build the app using the parameters that we defined in . We will achieve that by adding the flag to the build command: build.json --buildConfig cordova build android --release --buildConfig This command will build a signed apk that you can upload to Google Play. The location of the apk will be written as an output of the command, but the correct location should . be platforms/android/app/build/outputs/apk/release For more details on the installation, building, and signing you can go to the official Cordova Android Platform Guide Previously published at https://blog.codechem.com/signing-android-apk-with-apache-cordova

How to Sign Android APKs with Apache Cordova: A Brief Guide

Whether it is a solution they were looking for or a distraction they need, apps fulfill their users’ needs, hence the downloads. However, what happens when users have already accomplished their goal? According to a report published by , only 32% of users will return to an app 11X or more after downloading it. Moreover, 25% of the users abandon an app after one use. Statista With a competitive app market and struggle to keep customers engaged, how can app developers ensure that they keep their users for a longer time? Creating an innovative application involves more than just the interface. While you can build apps with impressive graphics and a smooth interface, developers should also consider other features that meet consumer requirements to encourage users to come back for more. The answer might just be into your application. integrating social features Come as users, stay as a community As applications explore more methods to ensure user retention, it’s crucial to examine other potential solutions to keep your users longer and eventually create an in-app community.

Stuck at home during the pandemic, people have resorted to socializing virtually. According to , 32% of Americans surveyed said they hosted or participated in virtual parties or social gatherings with friends or family. Pew Research Center And with more people going more virtual due to on-going social distancing and restrictions in social gatherings, it might be useful for developers to make their apps more social. More than the entertainment your app provides, users want to share their experiences with their , discussing the things they love and learning more from like-minded peers. in-app community Simple interactions such as Likes and Comments can also amplify in-app community engagement. Aside from being a good gauge for measuring engagement among users, comments and likes can also bring people who share the same interests. They can connect through posts on your users’ profiles and feeds. These social media interactions also help users get to know each other better, enabling them to reach out to more people online — even to those outside their circle. Indeed, the in-app community plays a crucial role in retaining users.

In-app social features can make them stay not only for fun but also with the bonds they forged with other users and your brand. Increase app engagement and retention Adding a social dimension to your app can lead your product to a whole new level. From in-app chat to live streaming and social commerce, you can bring your users together in one place, without them having to leave. In-app social features can aggregate the best functionalities from today’s social media platforms, thereby creating a thriving social network in your application. But why would you bother integrating social features into your app? Well, in-app social features can boost your user engagement and retention. As much as you think that you have the best mobile app there is, there is still a chance that your users can forget, or worse, delete them from their phones. Silicon Valley analyst said that an average app loses 77% of its DAUs within the first three days after they install. In an article from , they reported that 90% of users eventually stop using an app by a month, and three months later, only 5% of users continue using an app. Andrew Chen Android Report To counter this, adding an in-app messaging feature can .

Community Is

The Ultimate Social Experience

Social Features: The Secret to Bridging the Gap Between Apps and Users 

Water-cooler chats, all-hands meetings, lunch and learns, and after-work happy hours can often contribute to healthy company culture. But no one truly knows when our offices will return to normal. The shift to remote work and Zoom calls has made it difficult for companies to maintain a strong sense of office cohesion and to cultivate team-building activities for their employees. While it’s difficult to recreate the interpersonal aspects of the in-office environment, there are ways to maintain a unique and enjoyable office culture remotely. Promote Socializing The days of strolling through the office and talking to people are on pause. As such, introverts may find it difficult to take the proactive step of scheduling a friendly virtual hangout or calling a coworker just to catch up. Plus, many office interactions happen in passing; you can’t schedule “casual.” Companies should be mindful of this new dynamic and make an effort to establish social spaces where employees can simply enjoy each other’s company and maintain their bonds. Our executive team at has scheduled a weekly, voluntary meeting called “Remote” where any and all employees can sign in and talk about whatever they want. It’s a mid-week social hour that the team can rely on. They also host a weekly game of virtual Trivia. Employees are randomly paired off and the winning team gets a GrubHub gift card to help ease the WFH food prep stress. Not only do these virtual hangouts help coworkers stay connected, but they also offer a time to not talk about work. Have fun, get creative, and when in doubt, ask your employees for ideas! (Sidenote: offering food as a prize is a great motivator.) Density Cut Everybody Some Slack Slack is an incredibly useful platform. It’s also entirely overwhelming, and quite often disorganized. Putting up guardrails so team communication doesn’t break down is important. Consider encouraging employees to message mostly in public and team channels so the conversation can stay open to broader feedback and influence. While some communication needs to be one-on-one for either collaborative or interpersonal reasons, most project comms can be aired out over the proverbial roundtable. This way no team members feel alienated if kept out of the loop, even incidentally. Although many decisions need to be private, executive teams can try this as well. Doing so will maintain a more inclusive work environment and allow employees to feel included in the scope and direction of larger company goals. Try a Pechakucha A Pechakucha is an incredible way to allow employees to speak to and educate their colleagues about a topic that they are genuinely passionate about. This short-form storytelling medium that consists of someone giving a strictly 20 slide presentation on something that they are passionate about, the catch is, they only have 20 seconds per slide. While roughly six minutes does not seem like a lot of time to teach people about a topic, it is unbelievable how much information is transferred when you are truly passionate about the topic. This format can be done virtually and allows employees to learn something new. Resist Surveillance On its face, productivity tracking software seems to make sense. You might want to make sure your newly remote employees are putting in the hours they normally would at the office. However, just like learning, everyone works differently. Working from home may actually help certain employees find a better balance between “on” and “off” hours. Their final work product may be better because they took some time in the middle of the day to go for a walk or play with their dog. One benefit of a remote team is that it’s hard for any employee, whether they’re the CEO or a contractor, to skate by on time spent face to face. Which is to say, just because someone is in the office doesn’t mean they are actually getting the job done. WFH should have a results-based dynamic, where the job is either done or not. Progress is either made or it isn’t. Some team members may work 9-to-5 like they would in the office, but some may be night owls and shift their schedule to better fit the way they naturally work. Either way, overly surveilling your team members and keeping track of “hours spent” will likely foster distrust and negatively affect company culture. Host Idea Blasts Similar to an open forum, these “Idea Blasts” are meant to spark meaningful and collaborative conversations throughout the company. The general format of these Idea Blasts goes as follows: there will be a general prompt or problem that needs to be solved, it does not have to be directly related to the company, and randomized teams of employees will be broken into groups for a set amount of time to discuss creative solutions to the prompt or problem. These Idea Blasts are meant to bring together members of the company who don’t necessarily always interact with one another and promote a fun and creative way to collaborate. Ask for feedback No one understands your company's culture better than the people experiencing it every day. Empower your employees to provide constructive feedback on how it's going. Some employees may respond well to the above activities and social-hours, but some may not. What's the old saying about best-laid plans? Company culture is not a one-and-done project. Maintaining a healthy, productive, supportive work dynamic is an ongoing process that needs regular updates, management, and tangible goals. The last thing you want is for your employees to feel unheard. Google Forms, anonymous surveys, virtual Q&A sessions. You can use these to glean insight into how your efforts are or are not paying off and how you may be able to improve. Company culture is paramount. If you foster a collaborative and engaging work environment, your org will produce better products, attract top talent, and better yet, keep them around to grow with the business. The above list is by no means exhaustive, but it may help get you started. If you treat your team well, the distance between desks won't matter. Happy Zooming!

How to Preserve Your Remote Company Culture

The onset of cryptocurrencies came along with impressive innovations such as blockchains, which continue to spearhead their functionalities. Through blockchains, the concept of transactional throughput is significantly improving on various digital currency platforms. However, for blockchains to reach their full potential, operational nodes need to be in place to monitor and ensure a sustainable transaction system. Basically, running nodes and masternodes give users a new way of earning an income to run nodes and masternode services. What's interesting is that anyone can become a node operator and participate in validating transactions. Stake payments are the only requirements for interested users hoping to take part in the system as validators. Proof of Stake In essence, stake contributions help maintain a transparent network because nodes can lose their stakes due to any form of misconduct. For that reason, it becomes an obligation for nodes and masternodes to avoid any form of malicious activity that may implicate their positions as operators on a blockchain network. brings you a similar staking mechanism whereby you can run an automated staking and masternode operation and receive profits in return. While trying to educate the public on cryptocurrencies and blockchain advancements, MyCointainer is also in pursuit of providing straightforward and professional staking services. MyCointainer Where to Start MyCointainer introduces a simplified way of starting your staking journey in the digital asset ecosystem. Firstly, users will have to select a cryptocurrency asset they prefer from a diverse number of assets hosted on MyCointainer's system. After that, users transfer a certain staking amount to the ecosystem's staking wallet. Finally, the user will automatically receive regular profits as MyCointainer leverages the power of blockchains. Staking for more extended periods presents higher probabilities of garnering more incomes. Moreover, the staking network doesn't need any expert skill to navigate through it. Instead, the platform handles every technical detail and only aims at utilizing your hard-earned money for profit maximization. Supported Assets MyCointainer covers a wide range of PoS assets in the crypto economy. Since there is no minimum or maximum deposit amount, you can choose from a variety of digital assets each carrying different reward fees. For instance, a virtual asset like Cardano(ADA) contains a reward fee of 0.43%. In-Built Exchange As an integrated feature, MyCointainer will contain its own exchange platform. Therefore, users will be able to make exchanges and receive their desired coin out of all those hosted on MyCointainer. Designing an in-built exchange is an ideal way of ensuring users avoid going through the hassle of swapping coins from another exchange in order to stake with MyCointainer. More Details on Rewards, Withdrawals, and Deposits Earning on MyCointainer varies from the underlying math behind the masternode reward calculations and the particular coin being staked. However, the staking company's percentage rates are based on specific aspects such as the number of blockchain blocks. The good news is that some coins contain an inbuilt calculator that determines the approximate amount of rewards a user should receive. In the future, MyCointainer will eventually design a staking source data whereby users will have an easy time in determining the rewards from masternodes and which allotment is from the regular staking. MyCointainer will construct this feature by gathering and publishing the investor's staking information. Airdrop Giveaways giveaways are mechanisms that companies and developers use to attract new customers to their platforms. The platform owners do this by distributing free cryptocurrencies or in the form of gifts. Airdrop MyCointainer rewards users via airdrops for handling tasks such as registering, joining, or making comments on their social sites. Airdrops are also an effective way to create brand awareness and receive feedback from MyCointainer users on how they like the staking company's product so far. After receiving the airdrop giveaways, users can decide on whether to withdraw the digital currency, transfer it to another party as a gift, or use it to stake at MyCointainer. The airdrops are also automated functions that are circulated by trading bots. Safety Precautions Without a doubt, many people may prefer dealing with a regulated platform because it instills a sense of security towards the platform's participants. MyCointainer is a fully regulated staking ecosystem that displays all its legal details on the platform itself. Additionally, it conducts verification procedures for every account registering with the staking platform. The account verification is per the staking company's terms and conditions. Hence, failure to identify yourself can limit you from accessing some services such as withdrawal of funds. MyCointainer also carefully monitors and counter checks every transaction related to the different digital coins. To avoid compromising users' investments, the staking platform employs a (SAFU), which typically reimburses back investors in the event of hacks or any other breaches. Secured Asset Fund for Users The regulated staking institution further transfers and stores an investor's digital assets in cold wallets for safe-keeping. are technically safer since all assets are stored offline in a hardware device, thus becoming less susceptible to hacks. Cold wallets Third-party interventions come with several uncertainties and risks, especially when acting as custodial entities. As for MyContainer, honesty is their number one priority as they assure stakers or investors the ultimate professionalism to build a creditable and worthwhile staking/masternode company. Under lawful grounds, MyCointainer is licensed to offer fiat-crypto transfers and e-wallet services. Power Subscriptions feature takes you to a world full of PoS and masternode coins. Under this function, there are three levels, each containing different subscription plans. MyCointainer Power Power Zero is the first subscription level going for a monthly fee of 8.3 EUR. The second and third levels are Max and Percent, each with a monthly subscription fee of 9.80 and 39.90 EUR, respectively. Luckily, all levels charge zero fees on any withdrawals and 200+ exchange pairs. Another advantage is that there are 0% staking fees for every digital asset. Max and Percent subscribers receive VIP giveaways and offers worth approximately $200. Users also get in direct contact with a shared masternode system for diverse coins supported on MyCointainer. Another point to note is that the entire subscription process is automated, meaning users need to choose their preferred subscription level and watch their investments grow. Additional Power Percent Benefits In a bid to accelerate the worldwide crypto adoption, MyCointainer offers users a straightforward investment product that anyone can use through the Power Percent level. Besides, including the Power Percent level is another way to build and share the staking company with the community. That being said, Power Percent subscribers will enjoy additional benefits such as 100% staking rewards, access to a shared masternode service(with all assets), participation in worthwhile community projects, fully paid nodes automatically running to generate rewards, and monthly rewards distributed automatically courtesy of MyCointainer’s Partners’ contribution. A Company Open to Collaborations vision seeks to add merit towards both institutional and retail customers by providing a valuable product. Furthermore, it is the staking company's wish to make every individual feel the benefits of the services they offer while trying to fuel up the crypto mass adoption dream. MyContainer's Due to this reason, MyCointainer is open to working with new partners, platforms, or other entities to expand further with innovative projects. To be precise, MyCointainer is on the hunt for any interested parties, such as blockchain developers, who will be solely responsible for designing the platform's blockchain. Legal advisor positions are also available for anyone willing to extend their legal insight knowledge concerning cryptocurrencies and the overall financial industry. Professional marketers equally have a spot at MyCointainer to assist the ecosystem in raising a global staking audience. In simple terms, anyone with an innovative idea evolving around a decentralized financial system can reach out to MyCointainer for a fruitful partnership. Advantages of MyCointainer User Funds Protection To ensure user’s funds are safe from any unforeseen circumstance, MyCointainer transfers all its assets to a cold wallet, a safer way to store assets without an internet connection. In the event of a hack where users lose their investments, MyCointainer employs the Secure Asset Funds for Users which automatically compensates the affected users. Wide Range of Assets MyCointainer hosts a diverse number of assets under one roof. The 100+ assets are all PoS based digital coins that can also be accessed through the in-built exchange MyCointainer designed. Furthermore, the ecosystem supports some of the most dominant coins in the market such as Polkadot, Tezos, the newly founded ETH2.0 and many more. Passive Income Opportunities Through MyCointainer, users have the chance to stake their preferred digital asset and watch their profits grow. However before embarking on the staking and masternode journey, it is advisable to find out more (DYOR) on the asset you intend to stake. That way, stakers can determine and perhaps estimate on how profitable staking can get before embarking on it. The whole staking process is fully automated, therefore, users don't need to handle any complex details. Final Word Investing in the crypto space can be a bit hectic; however, MyCointainer introduces a more comfortable way for investors to generate adequate profits. Taking an automated approach is also an advantageous way of trading since it eradicates chances of  human errors that may occur when staking. Since focuses majorly on staking, block validation will ultimately become a popular earning mechanism in the digital currency ecosystem. In the end, transaction operations will grow to become more transparent and fast, which meets the overall cryptocurrency goal of revolutionizing the traditional financial system. MyCointainer

How Does An Automated Staking Ecosystem: A MyCointainer Review

How to be a good manager: Do The D.A.M.N. job. A couple years ago, right after my son (above) was born, I became a manager of an engineering team. It was an overwhelming time in my life, and I didn’t really know what to expect — I wasn’t handed a job description, just a title. My boss had registered me (and the other managers) for engineering management training, but that was a few months in the future. It was a bit anxiety provoking. How was I supposed to know if I was succeeding when there wasn’t a description explaining the job? So, I started with asking fellow managers. How do you do this role? The answers I got varied tremendously. It was almost like each manager made the position whatever he/she wanted it to be. So next, I turned to LinkedIn Learning. LinkedIn Learning has a collection of management courses. I completed a handful of them. These were helpful; but, also all gave different advice — too much for a new manager to handle at once. Over the upcoming weeks, it became clear to me that the definition of management is a much foggier than I originally thought; and so I set out to define it for myself. The overall goal of management I started with the overall goal/mission of management (as I saw it): Help your team accomplish goals as quickly as possible. I think engineering management is a purely support role — and it is awesome. You have a bunch of smart engineers who like to solve problems, but working on a team means there’s minutia and random administrivia that has to be done. Every minute where engineers aren’t solving problems is both: A. Wasted time for the company, and B. Probably something the engineer doesn’t want to be doing anyway. The number 1 thing you can do (as a manager) to help your team is to clear the path so they can solve the problems. And what that looks like in practice boils down to a few basic activities, which happen to create the acronym: D.A.M.N. 1. Direction. You are in charge of setting a clear direction for your team. Often, this direction is handed to you from above, but it is rarely “clear”. Your #1 activity will be continuously clarifying that direction and delivering it to your team. 2. Alignment. Your second priority is alignment. You need to ensure everyone on your team understands the direction (which is why it should be clear), and is aligned with it. 3. Motivation. Third, motivation. You need to ensure your team is motivated to actually drive toward the direction. The easiest way to ensure this is to just talk with each member. Ask them how they are feeling about the direction — and their alignment. 4. No blockers. Lastly, clearing blockers. This is slightly an extension of the Motivation part, but different enough that I put it in a separate category. Figure out what blocking your members and remove it. This can (frequently) be something outside of work. And that’s it. It really boils down to these four activities. They’re not complicated, but do take ongoing effort. If you can accomplish them, you’ll be a step ahead of other managers and your team will fly. What do you think? If your manager what are your key pieces of advice? Leave them in the comments below.

4 Focus Areas for New Engineering Managers Who Give a D.A.M.N.

It’s hard to believe that Street Fighter V is celebrating its fifth anniversary this week (February 22nd). recently revealed that the upcoming Season 5 Winter Update for Street Fighter V will bring new fighters and features to the game, including the fan-favorite Dan Hibiki. Capcom Other new features set for the game’s Season 5 update include a new V-Shift mechanic, a free stage, and another new fighter named Eleven. Dan Hibiki is back in the Street Fighter series with his classic movies, such as the fireball Gadoken and the Koryuken uppercut. His new move for Street Fighter V is the “Danretsuken,” which is a multi-hit punching move that sends his opponent flying through the air, and the EX version offers players an option for an even bigger combo. Rose is also back with her Soul Spark, which she can now use in the air. One of her new techniques for her moveset is an anti-air move called the Soul Bind, where she can throw her scarf into the air to bring her opponents back to the ground. Her V-SKill I technique is the Soul Fortune, which enables Rose to use tarot cards that will offer various benefits to her or have negative effects on her enemies. The Soul Satellite returns as Rose’s V-Skill II in the game. Also new for Season 5 is the V-Shift, which will be part of a free in-game update this month. This is part of the V-System and is designed to help players get out of sticky situations. With the cast of one bar of the V-Gauge, players can pull off a fully invincible backdash that will slow down time for a brief period, so players can plan out their next move to counterattack. If timed accurately, the V-shift will allow players to regain half of their used V-Gauge bar. A free bonus character for the winter update is a brand-new character named Eleven. Eleven will be available as a free bonus character for players who purchase a Season 5 pass. Eleven is a prototype for Twelve from Street Fighter III, and he has the ability to shape-shift into other characters. He was created by Gill’s secret organization. If players are still new to Street Fighter V, they can check out a Free Trial version that’s running until February 22. This is a trial version of Street Fighter V: Champion Edition, and it has all the characters from Season 1-4. Street Fighter V Season 5 Update Street Fighter V Season 5 kicks off on February 22.

If you searched for this article, you probably need to read someone's WhatsApp messages or view the shared media files. In this article, you'll find the best ways to access WhatsApp chats. I recommend that you take a look at all of them and choose the one that meets your technical skills and monitoring needs. Access WhatsApp conversations by synchronizing the web version with the device using the QR code. The main vulnerability of is the web version of the service known as WhatsApp Web. To access the target's account, all you need to do is accurately configure the analog WhatsApp in the web browser and later use the captured data for your own purpose. The only disadvantage of this method is the requirement for physical access to the target smartphone. However, it is only necessary for a moment. Use your social engineering skills to get the target's cell phone for a few seconds. Whatsapp GB To access WhatsApp messages, do the following: 1. Decide how you will read the target's chats: from your PC or smartphone. 2. If you want to access messages from your desktop, just open the web version of the website and enable the option “keep me connected”. 3. If you want to view WhatsApp chats on your smartphone: install a special application on your smartphone that allows you to start the web version. Go to the Play Market, type "WhatsWeb" in the search, find the app and install it. 4. The most challenging step. Access the target device. If the device is password protected, it would be quite difficult 🙂 ATTENTION! The target device must be online, otherwise, you will not be able to break into the messenger and read the WhatsApp chats. 5. After accessing the destination smartphone, go to WhatsApp> Menu> WhatsApp Web. Now use the destination device to scan the QR code of WhatsApp Web on your own device. Please note that for privacy reasons, the QR code data is changed once a minute, so you must read the code within this period of time. As a result, you will access all chats, dialogue history and contacts from the  WhatsApp profile. The advantages of this method include the fact that the profile owner will never guess that they are being tracked. But note that if the destination is for the WhatsApp Web menu in the app, they will notice that the PC version is also open. Either way, the target is unlikely to guess that conversations are being monitored by a stranger. Spy on WhatsApp messages by exporting a chat history to your email. This method is similar to the first one and is suitable for you if you have less than a minute to access the target device secretly. It only takes half a minute to access WhatsApp, but it allows you to read only the chat that was not removed by the target. Online monitoring of chats is impossible in this case. 1. Run WhatsApp on the target device and open the chat you want to read. 2. You will find the Menu icon in the upper right corner of the chat. Touch More> Export chat. 3. Then select to export the chat with or without media. 4. Select Gmail, enter your email address and tap "Export". If you selected a chat with media files, all photos, videos, and audios will be attached to the email and the chat texts will be loaded in txt format.

2 Ways to Access WhatsApp Conversations

Well. Let's start by examining what Serverless really means. What does Serverless mean? According to , serverless computing is a where the cloud provider manages the server and dynamically allocates the resource needed to finish the task. Wikipedia cloud computing execution model That means, as users, we are in charge of the logic only. We don't need to take care of the servers, capacity planning, or maintenance operations scale.

If we have data, or "big data" in one or more of our data lake/storages, like or we can run SQL query on that data without the need to build a pipeline or inject the data into distributed databases such as Cassandra or MongoDB. distributed computing tool that enables us to process distributed data AWS S3 Azure blob storage, This is a huge advantage, especially when we would like to interact with offline data without creating the pipelines or peek at completely fresh new data that was just sunk into the storage before replicating/transforming and saved into a dedicated Database. As with all cloud services, there is a need to understand the cost model. with serverless, we pay-per-use. That means that we pay for the amount of processed data. If we ran a query on 2TB, the prices would be calculated by the 2TB data processed. This can be more cost-efficient than having a dedicated pool of servers, depends on the company/group needs. select * Lead Photo by C Dustin on Unsplash Also published at https://towardsdatascience.com/what-is-serverless-sql-and-how-to-use-it-for-data-exploration-eadad1f1a036
