The Power Supply Unit is the bit of equipment that changes over the force gave from the outlet into usable force for the numerous parts inside the PC case. It changes over the substituting current from your divider outlet into a constant type of intensity considered direct current that the PC parts require. It additionally directs overheating by controlling voltage, which may change naturally or physically relying upon the force gracefully. The force gracefully is a pivotal piece in light of the fact that, without it, the remainder of the interior equipment can’t work. Motherboards, cases, and force supplies all come in various sizes called structure factors. Every one of the three must be perfect to work appropriately together. CoolMax, CORSAIR, and Ultra are the most well known PSU producers however most are incorporated with a PC buy, so you possibly bargain makers when you supplant the PSU. Power Supply Unit The force flexibly unit is mounted simply inside the rear of the case. On the off chance that you follow the PC’s capacity link, you’ll see that it joins to the rear of the force flexibly. The rear’s generally the main part of the force flexibly that a great many people will ever observe. There’s additionally a fan opening at the rear of the force gracefully that sends let some circulation into the rear of the PC case. The side of the PSU looking outside the case has a male, three-pronged port that a force link, associated with a force source, connects to. There’s additionally frequently a force switch and a force flexibly voltage switch. Enormous groups of hued wires stretch out from the contrary side of the force gracefully unit into the PC. Connectors at the furthest edges of the wires interface with different parts inside the PC to flexibly them with power. Some are explicitly intended to plug into the motherboard while others have connectors that fit into fans, floppy drives, hard drives, optical drives, and even some powerful video cards. Force flexibly units are evaluated by wattage to show how much force they can give to the PC. Since every PC part requires a specific measure of capacity to work appropriately, it’s imperative to have a PSU that can give the perfect sum. The extremely convenient Cooler Master Supply Calculator device can assist you with deciding the amount you need. ATX versus ATX12V Power Supplies ATX and ATX12V are arrangement details that are critical to separate when managing power supplies. For the vast majority, the observable contrasts simply address the physical association plug on the motherboard. Picking one over the different relies upon the kind of motherboard that is being utilized. The freshest norm, ATX12V v2.4, has been being used since 2013. Motherboards utilizing ATX12V 2.x utilize a 24-pin connector. ATX motherboards utilize a 20-pin connector. One circumstance where the pin tally becomes an integral factor is when choosing if a specific force gracefully works with your framework. ATX12V-consistent force supplies, despite the fact that they have 24 pins, can really be utilized on an ATX motherboard that has a 20-pin connector. The staying, unused four pins will simply sit off of the connector. On the off chance that your PC case has the room, this is a totally feasible arrangement. Be that as it may, this doesn’t work the opposite way around. In the event that you have an ATX power flexibly that in this manner has a 20-pin connector, it won’t work with a more current motherboard that requires every one of the 24 pins to be associated. The additional four pins were added with this detail to gracefully additional force through 12V rails, so a 20-pin PSU can’t give enough capacity to run this sort of motherboard. Something different that sets ATX12V and ATX power supplies separated is the force connectors they give. The ATX12V standard (as of variant 2.0) requires a 15-pin SATA power connector. In the event that you have to utilize a SATA gadget yet the PSU doesn’t have a SATA power connector, you’ll need a Molex 4-pin to SATA 15-pin connector, (for example, this one). Another contrast among ATX and ATX12V is the force productivity rating, which decides how much force is pulled from the divider contrasted with the yield of the PC. Some more seasoned ATX PSUs have a productivity rating beneath 70 percent, while the ATX12V standard requires a base rating of 80 percent. Different Kinds of Power Supplies The force gracefully units portrayed above are the ones that are inside a work station. The other sort is an outside force gracefully. For instance, some gaming comforts have a force gracefully appended to the force link that must sit between the support and the divider. Here’s a case of a Xbox One force gracefully that serves a similar capacity as a work area power flexibly however is outer and in this manner totally portable and far simpler to supplant than a work area PSU: Others are comparative, similar to the force gracefully unit worked in to some external hard drives, which are required if the gadget can’t draw enough power from the PC over USB. Outer force supplies are valuable since it permits the gadget to be littler and increasingly appealing. Be that as it may, a portion of these kinds of intensity gracefully units are joined to the force link and, since they’re commonly really huge, now and then make it hard to situate the gadget against the divider. A uninterruptible force flexibly (UPS) is another sort of intensity gracefully. They’re similar to reinforcement power supplies that give power when the essential PSU is detached from its standard force source. Since power flexibly units are regularly casualties of intensity floods and force spikes since it’s the place the gadget gets electrical force, you can plug the gadget into an UPS (or a flood defender).

Workflow Automation: Publishing Artifacts to Sonatype Nexus using Jenkins Pipelines

COVID-19 has been hitting the healthcare system pretty hard these last few weeks. In U.S. hospitals they are now facing critical shortages of equipment. As of the end of March, nearly 1 in 4 hospitals have fewer than 100 N95 masks on hand and 1 in 5 reports immediate need for more ventilators. Already back in February, the FDA reported shortages in drugs related to coronavirus. Why are hospitals so ill-prepared?  Take into account that 26% of U.S. medical goods are imported from China. Before the outbreak imports were costly due to high tariffs, and post-pandemic the Chinese factories faced labor shortages which slowed production. Hospitals and vendors also adopted practices like “just in time shipping” which reduces inventory held to increase cash flow, which leads to shortages when supply chains are disrupted. And despite the high cost of healthcare, Hospitals in the U.S. only make 1.8% profit on patient care. Hospitals simply can’t afford to buy more ventilators at $50,000 per unit. Situations such as these indicate that healthcare is becoming more of a business scheme than a public service devoted to saving lives. From 2009 to 2016 Mylan raised the prices of its life-saving EpiPen from $100 to $600. Mylan was later found to have bribed pharmacies to exclude competitors and benefited them with the exorbitant price hikes they imposed with their ill-acquired monopoly. It’s high costs of care that are making 1 in 3 Americans think twice before seeking treatment. Over half of Millennials and Gen X delayed or avoided care due to cost, leading to 125,000 avoidable deaths. Others simply can’t afford health insurance, with more than 8 in 10 coming from low-income families. Minorities make up 43% of the population but account for over 50% of the uninsured, with 22% Native American, 19% Hispanic, and 11% African American. Since 2016 the number of uninsured has grown by 1.2 million. That’s the consequence of mixing business with medicine, the healthcare system was already struggling to offer care to all patients. But now with the appearance of COVID-19, can they overcome a lack of insurance and supplies? Can the American healthcare system find a way forward after this pandemic?

The Social Impact of Mixing Business and Medicine

Every great empire in the history of mankind eventually disintegrated and fragmented into smaller states. Some of those states became empires of their own, sometimes larger than the predecessors. This is equally true in the business world. Airbnb is a well-known Silicon Valley unicorn and it makes $2.9B in revenue. It's most famous for turning the hotel industry upside down as it opened up an entirely new class of accommodation previously unavailable on the market. But few people know that Airbnb is an example of a much larger and more significant process: unbundling of online platforms. Airbnb is an offspring of Craigslist,  often dubbed "the most universal answer to all problems of humanity". Craigslist has been unbundled in many platforms (Airbnb being one of them, as an unbundler of the short-term rental market), whose combined revenue is now almost 20 times bigger than Craigslist itself. These challenger platforms, however, are no way secured from being unbundled themselves. One of them, , captures 80% of the revenue, while Airbnb commission is only 6%, which makes it particularly interesting. Another one, , targets long-term stays, which makes its business streams more stable and predictable. Le Bijou Sonder Will the grandchildren of Craigslist, Airbnb rebellious offspring grow even bigger than the last disruptor? Why you should care about unbundling Investors who understand the process of unbundling well, like , taught themselves to spot promising ventures at a very early stage, long before their merits become widely recognized. Such a skill gives those investors a competitive edge. Imagine what wealth would you amass if you recognized the unbundling of Craigslist early on and managed to invest at least 100K into Airbnb, Uber, Zillow or Indeed in the first year of their existence, becoming a major shareholder. Andreessen Horowitz So what is Unbundling? Unbundling describes the process of fragmentation of an existing market into many smaller and independent components. The main dominant market player is thus under assault from an inflow of newcomers who specialise in sometimes completely new sub-segments. The key to entry and success is often technological in nature. The newspaper industry is a good example. Before the advent of personal computers (and more specifically tablets and smartphones), the newspaper was the primary medium for information exchange. But the sudden emergence of the Internet completely changed everything. The newspaper’s role as an information exchange terminal was completely replaced by a variety of different and specialised tools (see below). As a result, many papers were shut and the surviving ones had to compete for a much smaller audience. The industry as a whole remains on a trajectory of decline. In almost all cases of unbundling, technology has played a prominent role. The reason why newspapers enjoyed such a long era of dominance is due to the high barrier of entry, erected by the high professional network (a pool of journalists and reporters covering a multitude of topics across the world) and distribution (getting the paper into as many households as possible across the country) costs. The Internet completely changed this by dramatically lowering the cost of both. Many journalists, including foreign reporters, work as freelancers and can be recruited easily on a per-project basis without having to be employed full-time. More importantly, the cost of distributing content in front of viewers has practically fallen to zero as news (and, in its broader form, social media information) is now accessed via smart devices. Unbundling of newspaper industry [ ] 1 The lesson of the story is that unbundling can happen to any player in any industry, so companies and investors need to be constantly alert for emerging threats to their market (which incidentally usually comes from out of the market). The new class of hospitality business Airbnb massively disrupted a stuffy, conservative hotel industry that had not changed in decades. Their software lets users of vacant properties (or rooms) with travelers who need one. It essentially brings two related issues together and solves them in a single stroke: The supply of hotel rooms in any given city is limited and travelers are forced to pay a premium on short-stay accommodation Many existing property owners have spare rooms/properties that are under-utilized and under-monetized. This is a classic case of matching demand with supply and taking a commission from each transaction. Airbnb is now the go-to platform for short-term travelers with a huge market value of $35 billion. How is Airbnb being unbundled? Of course Airbnb is not immune to unbundling, in fact it began quite some time ago already.  So the real question is how do you unbundle a multibillion-dollar unicorn? Just like most of the blue-chip juggernauts of the past, Airbnb was always going to be ripe for unbundling.  It typically takes place when a dominant company overlooks an emerging market segment (usually inadvertently due to their sizes or deliberately as a result of their strategies) which is then served by a new enterprise that quickly satisfies pent-up demand. Here are three growing market segments Airbnb isn’t catering for. Challengers in the luxury short-term rentals segment Airbnb dominates the mass market for short-term rentals and its target audience is the budget-conscious traveler. However, it is unable to cater for the high-end luxury travel segment because it lacks qualitative value in three core areas: security, brand, and service. Firstly, Airbnb is a technology platform rather than an accommodation provider. It relies on the owner of properties (hosts) to complete the final-mile service delivery. As a result, it has very little direct influence on the quality of service. There have been numerous incidents where guests’ financial and even physical securities were compromised by disreputable hosts. This is clearly a no-go for the luxury segment. Secondly, due to the mass-market nature of Airbnb, the brand is considered generic and rather low-end. To mention one is staying in an Airbnb property is like admitting that you fly with Ryanair. This is a particular turn-off for the luxury market. Lastly, most Airbnb hosts simply offer accommodation and do not provide any bespoke services (e.g. concierge, gourmet meals). Consequently, Airbnb is never going to penetrate this meaty new market of high-net-worth travelers who demand elegance and luxury in private apartment-style accommodation, without sacrificing any of the high-end services and features they could previously only find in 5-star hotels. Here are a few of the challenger brands in the ultra-high-end travel accommodation market that are looking to unbundle Airbnb. Website: HQ: United States 1. Sonder link Sonder is a Silicon Valley company that takes on multi-year leases on prime properties in many of the major cities of the developed world. It converts them according to their own unique specification and provides travelers with high-end hotel-style services. Remote customer support is available 24/7 and amenities are freely available to ensure the comfort of guests. "Given that there was such a movement from traditional hospitality to alternative hospitality, we saw that there would be an opportunity at a really massive scale to provide a customer experience that essentially resolves the two problems of consistency for the sharing economy and authenticity and uniqueness that is lacked in the traditional hotel model," Davidson, Sonder’s CEO. The investors . says valued the company at $1B Website: HQ: Switzerland 2. Le Bijou link Le Bijou is a Swiss property technology business with a valuation north of $900M that disrupts the travel industry. By taking on long-term leases on luxury properties across major Swiss cities and refurbishing them according to its precise specification, it controls the end-to-end customer experience. It uses cutting-edge technology (e.g. virtual assistant James, a combination of artificial intelligence and human-powered assistance) and ensures the security and privacy of the guests with zero human contact, something that Airbnb misses out on. According to Moonshot, a Hong Kong-based investment firm, “Le Bijou, with its perfect product-market fit and a powerful entry barrier (scale, brand, and technology), is well-positioned to reap high profitability and deliver a significant return for investors.” No wonder it has a large fan base that Steve Wozniak, John Sculley, a couple of royal families and even Jordan Belfort. Unlike most early-stage companies, it is open for private investors. reportedly includes Website: HQ: United States 3. Luxuryretreats link Luxuryretreats is a market leader in the global ultra-luxury travel sector. By matching some of the world’s most stunning villas with high-end travelers, it solves the property under-utilization problem for homeowners and provides high-end property accessibility for travelers. With a 24/7 concierge service, it is hard to go wrong. It is therefore hardly a surprise that Airbnb decided to acquire this company for over $200 million back in 2017. Challengers in the camping segment Long gone are the days when the only camping adventures you could have involved lugging around tons of heavy gear. Welcome to the new era of glamorous camping. Every year millions of people go on camping holidays where they can relax and enjoy getting immersed with nature again. Yet the Airbnb platform is ill-suited for the needs of campers (due to its property-centric business model). Fear not, there are now many superior alternatives ready to fill its place. Website: HQ: France 1. Gamping link A Paris-based company started by a group of friends who love camping. It is a platform that matches landowners with campers (and thus taking a commission in the middle). It operates predominantly in Western Europe and aims to provide a seamless, private and yet intimate experience for campers to enjoy nature whilst taking the hassle out of camping. Website: HQ: United States 2. Hipcamp link If Gamping is the entry-level land-matching service, then Hipcamp is the premium offering that brings campers close to nature without compromising on comfort. A predominantly US-based platform, it contains thousands of luxury camping accommodations (huts, yurts, tents, RVs) in some of the most stunning locations in the world. A true getaway portal to immerse yourself deep in nature and find inner peace. Website: HQ: United Kingdom 3. Camptoo link A highly specialized niche for matching mobile camping van (e.g. RVs, caravans) owners with renters. It provides a useful portal for road trippers who do not wish to fork out on expensive equipment whilst still enjoying the freedom of being on the road. Challengers in the medium to long-term rentals segment The rental market is ripe for disruption. Millions of tenancies globally still take over a month to sign, with tons of paperwork and even the need to witness signatures, even though almost all of these tasks can be performed digitally. Airbnb, being a short-term property sharing platform, therefore won’t be of much assistance. But these contenders might help. Website: HQ: United States 1. Rentberry link A platform that covers most large cities in the US and Europe, it provides a digital experience for tenants who wish to apply for tenancy. Instead of preparing tons of paperwork to prove identity and income, this process can now all be done digitally (including signature) in the comfort of one’s home. This saves time and cost for both landlords and tenants. Website: HQ: Netherlands 2. HousingAnywhere link Predominantly a European operation (however there are a few selected cities in the US), HousingAnywhere markets itself as having a premium pool of prospective tenants. As well as automating the tenancy application and payment process, it taps into a market ill-addressed by many players, namely mid-term renting (i.e. between 1 and 11 months). Website: HQ: Germany 3. Nestpick link Nestpick is a property amalgamation platform that aggregates listings on major property platforms (e.g. Airbnb, Spotahome) and presents users with a uniform view. It has a global reach and directs users to the relevant platform once selected. It does not hold any listing inventories by itself. The narrow opportunity window Unbundling is a natural course of action as a company expands and the industry mature. It is perhaps ironic that Airbnb itself started off as a result of unbundling and now it is subject to the same onslaught from challengers in areas it neglected. Consequently, smart investors are always on the lookout for assets that have proven profitability and delivers excellent ROI, as well as being future proof. The challenge is to enter the market just at the right time - when you already can recognize the future market-makers, but before it appears on the radar of big venture firms and spoiled with cheap money. In a world where , entering the market before it’s too late becomes harder and harder. the cash is trash Sources Andreessen Horowitz fund - Crypto is financial unbundling - https://a16z.com/ https://haseebq.com/crypto-is-financial-unbundling/

This is as they understand the software development life cycle of a product, enough to readily know what should be shipped pretty fast, and what needs more significant development time invested in it. 1. The Technical Product Manager Also, having worked with developers, or being one themselves, a technical PM is able to build strong relationships with developers and maximize team output. : APMs typically were most often analyst or data scientist before delving into product management. Their love for data gives them the insights that keep them fully informed about the performance of a product. 2. The Analytic Product Manager : Backgrounds in Advertising, PR, marketing, sales support, or other areas related to marketing, are common with Marketing Product Managers. Their expertise is pivotal through out the launch cycle of a new product as it is obvious to them what features of a product will distinguish it as valuable to the buyers and consumers, or if a feature should be discarded. 3. The Marketing Product Manager : This product manager delivers at all cost. They do whatever it is that is needed to achieve their goals, even if it means working their team 25hours a day. As rare as this type of product manager is, they are often found at fast-paced and high-growth environments. 4. The Get-shit-done product manager : VPMs think in long terms more than they think in short terms, regarding products. They are extra concerned with how a product impacts their vision for the company and not solely the need to release the product. These traits are typical of founders of startups or ex-founders. 5. The visionary product manager Pro duct Managers Division Knowing the type of product manager you want to become is one thing, and knowing the type of product you will like to work with is entirely a different cup of tea. Although the responsibilities of Product managers vary from company to company, product managers can be broken down into three major groups. : An IPM works on products for people inside a company. The core focus is to solve problems of the users in the company, which may enable the company satisfy their customers. 1. Internal Product Managers The output of internal product management is not for sales but to enhance the productivity of various aspects of a company's business. These internal products are mostly used by software-as a-service companies. E.g, Customer relationship management tool, human resources information systems, and membership systems e.t.c. Internal product management is often recommended for newbies, as the risk is lower than that of commercial products. Besides, it's indeed a safe environment for beginners. But don't forget the cliches around 'comfort zones'. IPM's KPI: Usage, Usability, Cost reduction, and comfort e.t.c. Business to business products are developed by companies for other companies. The key difference between this PM and internal PM is that the clients pay for the product. 2. B2B Product Managers: If there is any mistake with a new version of a product, it will be seen by the clients who are paying for your product. And the brand of your company could be jeopardized in the process—More risk. Regardless, the customer database of a B2B product manager is small. This is because the buyer (your customer) is not necessarily ,same as the person who uses the product. B2B PM's KPI: Profit, income, cost, and margin e.t.c. : This here, my friend, is the toughest to begin your product management journey, and perhaps, more rewarding. You will be needing more than grit, perseverance, smartness, and ability to work under pressure, to thrive. 3. B2C Product Managers B2C products are sold directly to the customer. Same person buys the product and same person uses the product. And the customer base is usually large, up to millions of users. This has the most risk! B2C PM's KPI: Basically to generate revenue.

Entry Level Resources for Becoming a Product Manager

Right now, many Americans are facing difficult times, with more than 33 million people filing for unemployment over the last eight weeks, the US economy is feeling the pressure. We are currently in one of the most difficult economic periods we have ever faced. What’s baffling most people is why the stock market is up almost 30% since March lows. How could that be with the economy shut down due to the coronavirus, oil reaching negative prices, and with so many people out of a job? And that’s not even taking into consideration the possible renewed trade war between the US and China… If you have concerns about putting your money back to work in the market, I don’t blame you. Fortunately, there is also a lot of opportunities out there if you know where to look. Companies that are not only following the market momentum but are also set to benefit from the ongoing coronavirus difficulties that we all face. The Big Shift into Tech As a coronavirus worked its way around the world, a new reality after the pandemic has become the norm. The trends that were already in motion have been sped up dramatically, giving people no choice but to rely on modern-day cutting-edge technology to survive. For those who have been following the markets, the tech-heavy NASDAQ composite index has been outpacing the S&P 500 index, as well as the Dow Jones industrial average since March 23 lows. That’s no accident. The coronavirus has changed how we do things. Some companies are feeling the wrath of change while other companies are relishing in the new tech-driven economy. Let’s take a closer… The Amazon Affect It’s no secret that Amazon (AMZN) was a favorite among many families before the pandemic. The ability to order nearly everything from the comfort of your own home and have it delivered directly to your doorstep in one or two days has been disrupting the shopping industry for decades. However, now, by being forced to stay inside, there is no choice when it comes to acquiring necessities. If we ever needed a kick in the butt to try Amazon Fresh, Amazons food delivery service, there would never be a better time. The advantages are pretty clear, not only do we get to avoid coming in contact with people who might be infected, but we also get to skip those long lines at the register. It seems like we weren’t the only ones to notice as Amazon the selling out of food quite rapidly. The technology giant was trading at a high of $2180 before the pandemic started. However, after a temporary setback to the market selloff in March, it exploded back up to a new all-time high $2475. And why not it had first-quarter revenue totaling $75.45 billion, blowing past the estimate of $73.69 billion. Should we have known when the company was scrambling to hire 175,000 new workers? Amazon has so much demand, its famous prime day, originally scheduled to happen in July, has been postponed because it doesn’t think he can handle the demand. A New Way to Work and Play With a shelter in place order in the works, how are kids going to attend school and parents work? Another company that became an instant winner right out of the gate Zoom Video Communications (ZM). Most of us likely never heard of Zoom Video Communications before the pandemic, but you’d be hard-pressed to find someone now who doesn’t have someone in their household using the remote classroom and work platform. Both the kids in my household are using it as a remote classroom, while my friends and I used it to talk smack to each other during our online poker games. According to Zoom, they saw a 50% increase in business by the first week of April. They are now hosting more than 300 million daily meetings for its users. Easy Collaboration Advancements With more people working from home, tools that make collaboration easy among colleagues is a must. This is where Slack Technologies (WORK) can thrive. Slack’s enabled users to get only information that was relevant only to them, which dramatically speeds up communication and efficiency. The company’s chief executive, Stewart Butterfield, stated the company had 7000 new users in the first quarter, then just one week later added another 2000 users. Butterfield added that existing customers are expanding their usage and more “Enterprise deals are getting done. More new teams are signing up. More upgrading to paid plans.” Do people and companies want better collaboration tools… You bet! The Giants Gets Bigger All the companies growing in today’s environment need new technology to expand their business, this means they also need an increase in storage in a higher demand for data. Someone has to supply that. Video companies need to store their shows, supply chains require a place to keep up with their inventory, and everyone wants to keep a database on their customers and their past purchases. This is precisely what the companies building the cloud supply. Push button storage is what companies need to build out their data infrastructure without having to continually be reinvesting in additional servers. This is where companies like Microsoft, Amazon, and Alphabet take the reins. Cloud service enables companies to concentrate on what they do best instead of putting time, money, and people into maintaining their data. Microsoft has stated that they saw a growth of 59% just due to the coronavirus. Amazon Web Services also reported that revenue rose by 33%, while Google Cloud saw sales growth of 52%. Microsoft also has a similar story to Slack when it comes to their Team collaboration service. According to the technology giant, Microsoft said it had a 775% jump in demand in Italy. Overall it added as many users in a week as Slack has added since our inception. Technology is Quickly Changing the Way We Live All of these changes are happening in front of us right now. You can let them pass you by, or you can jump on board and profit along with the new economy. There are many potential winners out there, so far, I’ve only touched the tip of the iceberg. Companies like Smartsheet (SMAR), sells affordable productivity tools, or BlackLine (BL), which provides automated accounting software, or Chewy (CHWY), that allows pet owners to order pet supplies online, just to name a few. With so many people being forced into a new reality, those who would typically be laggards to adopt new technology are now being forced to expedite their path to innovate, thus causing a dramatic surge in the technology sector. Don’t get me wrong, price still matters, so investors need to walk a tightrope between growth and attractive capital gains. Going forward, our lives will be more technology-driven, and the stock market is going to reflect that. For those looking to step in and benefit from the new reality, the best advice I can give you would be to look at applying the right to the stocks that are reflecting the technology demand of the new economy. The trends we see playing out today represent the vision of the world to come. option strategies -- To take advantage of the new world landscape and learn options trading for free visit OptionStrategiesInsider.com

The Coronavirus Has Forced Us into a Tech Reliant World

In developing my Chrome Extension , I believe I have hit the perfect balance between keeping users focused on their task while also distracting them with what your app has to offer. Serenity Serenity is a unique game like productivity management tool with website blocking capabilities. The user enters blacklisted sites and a time period for which they are working. This data is then used to create a digital cityscape drawn on a canvas in the extension's popup. Here is the trick: time in this imaginary city passes in proportion to real life. However, if you visit one of your blacklisted sites, time in this world speeds up. The user is allowed to visit their blacklisted sites, this is not one of those impermeable wall productivity tools. The reason the user does not want to speed up time in this digital city is because there is a lone worker in his apartment who has the same task as you, finish his work in the time allotted. However, for him, there are 12 hours on the clock. When those 12 hours run out... it's rush hour. This seems involved but quite honestly it isn't. The methodology I am using is reminiscent to an electric collar for a dog. The first couple of times the user might accidentally visit a site they aren't supposed to, triggering a popup from the extension and an increase in the hours passed. However, this small jolt should serve as habit builder. The user will eventually remember that they are trying to restrict themselves and potentially begin to care about their progress in the game. Once this acceptance of the app into the user's daily routine occurs, it is then a question of distracting the user with interesting enough mechanics that inadvertently keep them focused on whatever task they are working on. You want the user to periodically click on the popup on their own will not on your outside influence. If you have to nag and remind the user to  click on your app, they never will. Based on my experience developing apps like Serenity, simplicity is key. You need your idea to be simple yet helpful and alluring. Now that might seem like an unrealistic goal, it isn't. The only thing holding you back from accomplishing this is knowing where and when to stop developing features. If you keep adding features to your app out of pure boredom, you're not helping anyone. Developing non-essential features sucks the life out of the developer and the user. Things that come out of your brain make perfect sense to you but inherently are confusing to a new user, at least at first. If you bombard a user with a plethora of features, many of which aren't particularly helpful, it will deter them from using whatever you have made. I created this application because I felt there was a huge gap in the productivity market. Everything out there was either a strict website blocker who forced you into their mold too quickly, or was too lenient and served as more of a meditative service. There is an extremely important yet extremely fine line which all developers need to be wary of when developing an application which is aimed at altering a user's behavior: how to become a part of their routine without annoying the hell out of them. Quite honestly, I think this idea might be working (at least a little) with those who enjoy using productivity applications. Getting featured on was a huge hint that people liked what I was doing. App development always involves treading carefully and creating a system which respects the user's boundaries. product hunt In productivity, based on my findings and mild success with Serenity, I believe this involves a very precise amount of distracting the user from what usually distracts them. If you can deter their attention away from sites they visit leisurely and point it instead towards your app and then by association their work, it is a win win scenario.

Here are the top ten decentralized applications with Ethereum protocol, according to on May 17th: Dapp Radar Their daily user total is less than 9,000. Total. Feels like that is missing like 3 or 4 or 5 zeros to be the most programmable anything amongst the . 4,400,000,0000 active internet users I checked the #1 DAPP, : Uniswap to confirm usage In the last 24 hours, there have been less than two thousand humans who have used Ethereum's most popular DAPP, if I'm reading this correctly. The 24 hour volume of transactions is more impressive at $4,470,874. This puts the average transaction total per daily user at $2,306.96 (i.e.  $4,470,874 / 1938) and average price per transaction at $834.43 (i.e.  $4,470,874 / 5,358). I visited Uniswap.com to learn more about what the business does, and saw this: Then I realized I was supposed to go to https://uniswap.org/ Is "automated liquidity" a euphemism for "free money" ? How many of Ethereum's DAPPs are finance specific? And does that matter? Wide spreading technologies powere applications across many industries, but fintech is also known as an early adopter of many breakthrough technologies. So I looked into how the internet measures Ethereum Dapp usage versus site traffic: All that $$$ raised in Ethereum via ICOs.... and not one top twenty thousand digital destination is built as a Ethereum DAPP, apparently.

Over the past 4 years, I have been exclusively operating on AWS as my cloud computing platform. AWS offers so many products, what I have used is a small portion. However, what never has stopped impressing me is each of these products I use is constantly getting improved. AWS also has established a mature eco-system, new offerings are taking advantage of the platform as a whole to greatly reduce customer's learning curves. Sweet Spot of Amazon Fraud Detector Today, at AWS Summit USA and Canada, I have learned about . As a fraud prevention professional who has 1) evaluated various fraud solution vendors and 2) attempted to build a generic fraud solution offering to serve others, a product from AWS excites me, because: Amazon Fraud Detector Many businesses not only have built their main customer-facing products on AWS, but their Data Warehouse as well. A fraud product requires essentially data warehouse to build fraud models and rules, and runtime to serve the solution. These businesses already have both on AWS, it's much easier to naturally use Fraud Detector than investing on integration and transporting data to a 3rd party fraud vendor. For existing AWS customers, they already have invested in learning AWS and how to best utilize all the products and infrastructure. For example, Fraud Detector will use IAM for access control; will likely use CloudWatch for operational logs; will hopefully run the detector in Lambda. So customers' existing tooling and investment will be retained, thus, lower cost to adopt. When we worked with fraud vendors, we compared vendors with in-house fraud solutions for pros and cons. The biggest selling point, in my mind, from a vendor was so-called "network effect". The in-house solution might be technologically more advanced, but we only got to see fraud patterns we had seen; vendors, on the other hand, would work with multiple clients, and had access to much broader fraud patterns and data sets. Amazon Fraud Detector claims that they will augment the customer training features with insight gained from Amazon.com fraud fighting. If this is true, it's going to be a huge lift compared to in-house efforts. Random Thoughts Fraud Templates The preview has demonstrated a model template "Online Fraud Insights", which predicts if an activity is fraudulent by requiring email address, event time and IP address of the activity. "Account Takeover" and "Transaction Fraud" templates are planned. While I understand the benefit of templates (to understand the semantics of features so AWS can augment and transform), there may be 2 challenges: In real business, although those 3 may be common fraud use cases, there are many other fraud vectors, some of them may be specific to the business itself. For any particular fraud vector, the useful features can vary greatly business by business. In addition to email, time and IP, for example, browser user agent might be predictive, too. I hope to see Fraud Detector figure out how to support the much needed flexibility on top of templates. Model Performance Analysis I love how Fraud Detector includes AUC, Score distribution and Confusion matrix for users to choose the right score thresholds (possibly more metrics in the hidden Advanced metrics). It's straightforward to slide the score and see the dynamic true positive and false positive rates, to optimize for the best score cutoffs. Expressions in Rules When writing decision rules, the available variables include those supplied in the training data set (email, time, IP), plus the model score. What would be exciting is to offer the augmented and transformed variables, which AWS has added insight to, to rule writing as well. Amazon Fraud Detector Preview is available in us-east-1. I've applied for access, and will review more once I get my hands on it.

The Implications of the Amazon Fraud Detector

We are always talking about the mainstream programming languages to an extent where Python, Java, SQL, etc, are all that we see mostly. There are many other dynamic frameworks and languages like our topic of choice today; C sharp or C#, which are playing an integral part in global software development communities. Let's take an in-depth look at the fundamentals of C# as well as the .Net framework to better understand the exclusivity, features, and their advantages. Computer programming languages are either reliant on platform or framework to function despite mostly being standalone products. C# or C sharp is a hybrid language of not just C or C++ but is inspired by , Modula 3, Eiffel etc., and run on .Net framework. design and features of Java This article is focused on explaining the fundamentals of a programming languages as well as the essentials of a platform the language is dependent on. So, let us begin then! What is C#? C# is a general purpose language that was developed by Microsoft to contest with Sun Microsystems’ reflective language called Java. It employs web services based on extensible markup language XML specification powered by World Wide Web consortium W3C. object oriented programming The XML enables programmers, developer, designers etc., the customizing liberty to create tags, transmission, definition, validation, and data interpretation applications and organizations. There are many C# features like garbage collection, type declarations, type-safety, versioning & scalability support etc., that authenticate its design to improve the productivity and make web applications development easier for MS strategic block approach’s extension called component object model COM+. This structured language is also recognized by international standards bodies like (ECMA) and International Standards Organization (ISO) as a standard that led to various companies developing C# variations. European Computer Manufacturers Association There are many high tech organizations such as, Apex Software, devSoft, FarPoint Technologies, Bunka Orient, Component Source, LEAD Technologies etc., that have C# supported frameworks as a fundamental foundation. How Does C# work? C# works by combining the computing power and programming ease of to facilitate services and information’s smooth interchange on Web. The MS aimed to simplify programming through the integration of XML and simple object access protocol (SOAP) to allow developers to create highly scalable and portable applications. C++ & Visual Basic The XML and SOAP specification provides programmers object and/or method programming accessibility without the need for additional code on every step of the program. Which makes C# programming swift and inexpensive because building on existing code instead of repeatedly duplicating the whole exercise makes for an expensive MO to bring forth new products and services. General Features of C# Due to the overall inspiration and the inclination, the basic construct, thus features of C# are similar to various high-level languages. object oriented and component oriented Yet, the general and distinguished classifications of wide ranging C# features set the language apart from other programming languages in terms of variety of functions that translates in highly competitive programs and software applications. Some of the general C# programming features include: Simple Modern Programming Language Object Oriented Type Safe Interoperability Scalable and Updateable Component Oriented Structured Programming Language Huge Library Speed These are only few of the general features for a multi-paradigm programming language like C# include long arrays of programming disciplines. Each comes with its own set of features to be able to make the supportive of software engineering principles. C# implementations This compatibility facilitates the development of software components that can be deployed in any distributed environment. The process for all the meticulous engineering requires exceptional features to assist the programmers in their developing endeavors. The distinguished category of frequently used C# features include: Boolean conditions Automatic garbage collection Meta programming Delegates and events management Probability Indexers Conditional compilation LINQ and lambda expressions Exclusivity of C# Since 2002, the time of C# inception with .Net framework 0.1, the language is continuously being subjected to revisions in coordination with .NET updates to now become one of the most popular programming languages that creates Windows programs as well as . Although, to an extent C# is a derivative of C and C++ and naturally has similar operators, object oriented case sensitivity, identical syntax etc., there are some major distinctions that sets this multi-paradigm language apart from all its applied languages. web applications Following are some of the noticeable differences between C# and C++: The pointers of C or C++ e.g., are used as objects with methods and properties in C# programming. C# does not recognize data types such as Boolean or bool as integer like other languages do. The representation, function, and call upon of many keywords like typedef, default, extern, delegate, static etc., are completely different in C# than they are in any of the inspired programming languages. The case to case fall through of switch statement in C or C++ programming is not supported by C#. C++ support for global variables and methods does not extend to C# programming. Since C# was designed for specific Microsoft's .Net framework, the developers have access to not only feature of C# itself but to all the features of .Net application programming interface (API). While that serves to provide huge benefit, the .Net framework dependability also render C# applications run limited to platforms that are .Net runtime supportive platforms e.g., Windows, Windows server & phone etc., unless the codes for C# programs are first compiled through some conversion tool like that of Microsoft .Net native. What is .Net framework? .Net framework - pronounced and often written as dot net – the to principally run on Microsoft applications. The .Net is central component to MS overall development strategies as well as its Java auxiliary in MS development environment. Microsoft developed software framework Its huge standard class library called framework class library (FCL) enables wide ranging language interoperability among various programming languages where all the languages are compatible with codes written in other languages and yet be referred as managed code. For the .Net framework performs in software exclusive environment like application virtual machine called common language runtime (CLR) – MS implementation of common language infrastructure (CLI) - that along with FCL sustain the whole platform. While CLR facilitates security, exception handling, thread execution, and memory management services, the FCL enables development of network communications, web application, and numeric algorithms by providing database connectivity, data accessibility, and user interface. The MS has also created an integrated development environment called Visual Studio for Windows applications that are developed by aligning the .Net framework supported code with various libraries. Principal Design Features of .Net Framework The primary objective of .Net framework design is to increase the productivity and minimize the margin of programming errors through into the software structure. modular approach integration This MS software development framework provides Windows exclusive operating systems (OS) software’s smooth development, installation, and execution through controlled programming environment which is orchestrated by the following feature: Interoperability: It facilitates the accessibility for programs developed in .Net to the functionalities of programs that are developed outside of .Net framework. Common language runtime: The CLR or sometimes also regarded as common runtime engine, streamlines the common behavior among .Net framework supported programs’ thread execution, memory usage, security management, and exception handling. Language Independence: This independence stemmed from common the specification of common language infrastructure enables data type exchangeability among programs that are developed by using various languages at the same time. Base Class Library: It is basically a code library comprised of several encrypted functions from common to exceptional usability to prevent code repetition or rewriting for same purpose. It allows programmer enhanced productivity and few errors. Ease of Deployment: .Net frameworks has number of in-built tools that ensure easy program deployment - installing to execution - without disrupting the environment created by formerly installed applications. Security: .Net security is known for its compelling solutions that are based on a transparent control security model. .Net developed software applications are put to through specific model for the code behavior monitoring in all circumstances for the purpose of risk mitigation in applications including client, web, and server-side. How the .NET Framework works The .Net framework is a concentrated developer platform which is comprised of several tools, libraries, , and features to develop widely varying applications. It works by compiling the source code of one language in an intermediate language (IL) that is usually put in disk storage in a file called assembly which can be executed. programming languages Since .Net, MS developed programming infrastructure to develop, deploy, and run multiple services and applications e.g., desktop and web app that are based on .Net technologies, the assembly file contains directions of information for security and type of used code. After the assembly file is uploaded and validated by the CLR, the IL compiled code is interpreted to become instructions written in native machine code. The .Net framework utilizes three principal process fragment that include: Common language runtime Framework class library ASP.Net Implementations of .Net framework .NET Framework led to a grand family of multiple .NET platforms e.g., Net, .Net framework, and .Net core - beside the primary implementation of entire MS .Net technologies that are designed exclusively to accommodate object code regardless of the storage and execution - that are individually focused on: Mobile computing Embedded devices Alternative operating systems Web browser plug-ins The .Net framework is consisted of various implementations that allow codes developed in this MS environment to execute in number of different platforms such as, Linux, macOS, Windows, iOS, Android etc. Following are some of the most frequently used .Net implementations that include: is the primary implementation of whole .Net family which is used to support websites functionality, web & desktop app development, delivery of numerous IT services, and much more on Windows operating systems. .Net framework is an open source cross-platform implementation that also supports websites functions, IT services along with the development of console apps on not only Windows, but also on Linux and macOS. .NET Core is .Net framework’s developer platform for mobile implementation that supports application development, running, and functionalities on almost all of the major mobile operating systems, including iOS, Android, tvOS, watchOS, macOS etc. Xamarin/Mono is a not an implementation itself but is more of an API specification that lies across all .Net implementations for the purpose of facilitating the usability of the same code and libraries to smoothly run on number of different implementations. .NET Standard There is also a reduced version of .Net framework known as .Net compact framework which is available for various Windows CE platforms along with Windows mobile devices e.g., smartphones. This micro variation of .Net framework was developed to basically encompass devices that are extremely resource constrainedly embedded. Some of the compacted .Net implementations include: – essentially a web browser plugin Silverlight - is compatible with variety of web operating systems and smartphone operating systems such as, android, etc., along with being customizable into game engines. Mono iOS - is focused on cloud computing, cross platform suitability, and universal Windows platform (UWP) accessibility. .NET Core Advantages of C# & .Net programming C# being object-oriented language allows modular application development and code reusability. The CLR integration makes for C# programs’ smooth assimilation with code component from other languages. The .Net framework support make C# programming interpretable among all .Net technologies. Due to the formal all-set method approach, the C# coding becomes significantly more intelligible and eliminates the need to be concerned about header files. The massive choice of Microsoft stack and rich library, the C# provides tool for just about every function and implementation which allow programmers to freely experiment with new compositions and code compilation. The .Net framework provides in-house MS support for C# programming which is quite unlike other languages where programmers are solely dependent on communities for support. Backward compatibility arises from Microsoft continuous discarding of old Window platform which requires .Net framework upgrade. The externally instilled need to incessantly improve the configuration serves to give user afresh motivation to work hard.

Learning Fundamentals of C# and .Net Framework

I'm working on a system for positive behavioral recognition and metrics using Firebase and React. This is a hobby/side project that I work on usually on nights and weekends. This weekend I had an issue with Firestore (the newer of the two data solutions inside the Firebase product). I was querying on multiple data attributes in a collection. This is not allowed in Firestore, unless you have created an index that includes those two attributes. I had no such index, so I got this error: Does that say, "You can create it here:" ? Yes, the short answer is that that link says, "You can create it here." And you can click on it and it takes you to the page where you can build the index. AND... And it has pre-populated the index for you with the two fields that you need so that you can click, "OK". And the index builds, just like you need it: OK, thanks, that was easy. This is really pretty amazing and I have never seen an error like this. Often, errors are very generic and it takes time to search through forums trying to find someone with the same error who is actually having the same problem as you. I have seen a number of errors in React that offer suggestions as to where your bug is and they are often correct. This is very helpful and a huge improvement. The Firestore error takes that level of customer service to a new level: here's your problem, here's how to fix it, and here's a link that will basically fix it for you. I would very much like to see more of this. What has happened here is that someone at Google (Firebase is a Google product) has applied the ideas of user experience to the error handling in their product. Developers are the users of the error system, so thank you for that! Firebase is a web-based product, so there is no reason why it can't know enough to point you in the right direction. If you are in software development, though, you can appreciate that this is a high bar to jump over: Someone had to think of this early on, so that it could be woven into the product. Leadership had to include time and budget to implement it. Their UX had to be consistent enough to allow it. The error system handling system had to be built smart enough to make it all work. All of this to say - a lot had to happen technically, organizationally, and culturally to make this happen. When you think about the amount of time that often goes into error handling and management, it makes this all the more amazing. Developers are the users of your error system, your API, your toolkits, and your documentation. Doing things like this makes your tool attractive to developers, managers, and business decision makers. Why managers and business decision makers? Because it makes good developers better and faster, and it makes new developers far more productive than they would be if you didn't have it. New developers spend a lot of time searching for answers online and asking more senior team members for help. Imagine a world where the platform itself can answer your questions and guide you through solving the problem. Kudos to Firebase/Google on an amazing innovation.

The Best Error Ever: Firebase Errors for Humans

Web accessibility is important. Making your app accessible is morally the right thing to do, it helps you win more business, and it may even be legally or contractually required. However, not many software engineers or web designers know how to make their apps accessible. The W3C has published its , and these recommendations have been publicly available for a long time. However, this document is long and complex, and it’s difficult to get through and to understand. Web Content Accessibility Guidelines The Solution Checklists are easy. They give you actionable things to do. So, without further ado, I’ve compiled a for complying with the standards found in . This checklist can be used by software engineers, web designers, QA engineers, and anyone else that has an interest in making their web applications more accessible. web accessibility checklist WCAG 2.1 AA See something missing? Let me know in the comments below. Web Accessibility Checklist Note: I’ve grouped the checklist items into related sections in as logical a way as I could. There may be some overlap between sections. Buttons ✅ Buttons are used for triggering actions, not for navigating. ✅ All buttons have clear labels explaining their purpose. ✅ Icon-only buttons have an attribute that provides additional information for screen reader users. aria-label ✅ Buttons have contextual labels that provide information for screen reader users about which item this action is being performed on. (For example, if you have a list of 10 items in a to-do list, and each one has a Delete button, you need to provide a contextual label in the form of an on each button so that the screen reader will see something like “Delete item: walk the dog”.) aria-label ✅ and elements with click handlers are not used in place of button elements. div span Links ✅ Links are used for navigating, not for triggering actions. ✅ Links have contextual labels that provide more information for screen reader users. (For example, if your text is simply “Read more”, either change the visible text to “Read more about web accessibility” or else leave the text as “Read more” and add an that says “Read more about web accessibility”.) aria-label Images ✅ Text is not used in images. ✅ Each image has an attribute. (Background images or other images that you want the screen reader to ignore can have an empty attribute like .) alt alt alt="" ✅ Alt text describes the intent of the image, not describes the image literally. Headings ✅ The page has one and only one element. h1 ✅ The first heading on the page is an element. (Usually. If you have heading elements inside the navigation, you may make an exception.) h1 ✅ Heading levels are not skipped. (For example, an element must not be followed by an element without an element between them). h2 h4 h3 Forms ✅ All inputs have associated labels. ✅ Placeholder text is used for example input and not as a label. ✅ Formatting expectations for user input are displayed. ✅ Required fields are easily identified. ✅ Color is not the only indicator for feedback. (You should use a combination of color, icons, and text.) ✅ Error messages are helpful and appear close to the input. ✅ Every element is reachable by the keyboard. ✅ Inputs and buttons have focus indicators. ✅ Tab order makes sense. ✅ and elements are used to group inputs. fieldset legend Modals ✅ When closing a menu or modal, focus is returned to where it was previously (for instance, back to the button that the user clicked to open the modal). ✅ When a modal is open, hitting the Escape key closes the modal. ✅ When a modal opens, focus starts on the Close button or on the first element inside the modal. ✅ When a modal is open, keyboard-only users and screen reader users are restricted to only interacting with the content inside of the modal. (They should not be able to focus on, read, or interact with content outside of the modal in any way). Tables ✅ Tables are not used for layout purposes. Tables are used to present data. ✅ Tables have clear headings on every column or row (use the attribute). scope Toasts ✅ Users have enough time to read and respond to toasts or other messages on the screen. (For example, toasts generally shouldn’t disappear automatically after a few seconds, especially if there are buttons in the toast that a user may need to interact with. It’s a much better practice to allow the user to dismiss a toast when they are ready.) Drawers/Panels ✅ Content that expands and collapses allows the screen reader to read the current state for whether the content is expanded or collapsed. Color ✅ Text has a color contrast ratio of at least 4.5:1 between foreground and background. (Note: Logos and disabled interactive content have no color contrast requirements.) ✅ Large text has a color contrast ratio of at least 3:1 between foreground and background. Skip Links ✅ The very first element on the page is a visually hidden button that appears when focused on and allows the user to skip past the navigation to the main page content. Touch Targets ✅ Touch targets are at least the size of an average person’s finger (at least 44x44px). ✅ There is adequate space between touch targets. Focus Indicators ✅ It is easy to see what element is currently active or focused. ✅ Focus indicators are not color-only. Typography ✅ The base font size is around 16–20px. ✅ or is used instead of to create a more responsive experience when changing the font size. em rem px ✅ Text that is in all caps is cased normally in the HTML and transformed to all caps using CSS. ✅ Content is not aligned “justified”. Language ✅ The attribute is present on the tag. lang html ✅ Content that is in a different language than the rest of the page is wrapped in its own attribute. lang ✅ Abbreviations are inside tags and also have a attribute included which contains the full name (for instance, the full name of an organization if only the acronym is shown on the page). abbr title Layout ✅ The user can increase the font size of the text on the page by up to 200% without loss of content or functionality. ✅ The page layout doesn’t require the user to scroll both horizontally and vertically. (Preferably, only vertical scrolling is needed.) Audio ✅ Audio has a transcript provided either inline or as a link to a text file. ✅ Audio is not autoplayed. ✅ Audio longer than three seconds can be paused or stopped by the user. Video ✅ Video is captioned or has a transcript provided either inline or as a link to a text file. ✅ Captions can be toggled on and off. ✅ Non-visual cues are narrated/captioned (for example, when a character laughs). ✅ Video is not autoplayed. ✅ Video longer than three seconds can be paused or stopped by the user. Screen Readers ✅ All visible text can be read by a screen reader ( , , ). VoiceOver JAWS NVDA ✅ All interactions can be completed using only a screen reader. ✅ The screen reader makes an announcement if the page content changes significantly (for instance, new search results have loaded or page content has been filtered by some criteria). ✅ All error messages are announced by the screen reader. ✅ When content is deleted or removed from the page, focus is moved backwards to something previously seen rather than forwards. ✅ Screen readers can focus and read disabled elements (for example, a disabled button). ✅ Content that is inherently inaccessible, like drag and drop functionality that requires a mouse, has an alternative implementation that screen reader users can use. Keyboard-Only ✅ All interactions can be completed using only the keyboard. ✅ There are no keyboard traps (places that you can get into via the keyboard but can’t get out of via the keyboard). ✅ There are visual focus indicators for every focusable element on the page. ✅ The tab order is consistent, and focus moves through the page in a way that makes sense. ✅ Tabbing with the keyboard does not focus on disabled elements (for example, a disabled button). ✅ Content that is inherently inaccessible, like drag and drop functionality that requires a mouse, has an alternative implementation that keyboard-only users can use. I hope this checklist greatly simplifies your discussions as a software company regarding making your application accessible.

Web Accessibility Checklist For Your Project

is surely one of the places you want to consider for your project or startup. Below you'll find key information to get your work promoted on PH. ProductHunt What to know before launching on ProductHunt ProductHunt is one of the sites which can send major traffic your way - if prepared well. As with many sites, a low-effort posting will get little attention. Make sure to prepare your launch with: a catchy tagline (60 chars maximal) a great icon, ideally animated (240x240px, max. 2 MB) graphics (1270x760px) an engaging text with emojis to tell your story maybe a product/project video (if possible) If you've got a personal blog, make sure to prepare a post before launching. It helps to have it ready and just publish it with the project. Same goes for a newsletter of course. If you are not a technical person and struggle to get decent graphic prepared, check out . That's an easy drag-and-drop web-based graphic app with the complexity of, for example, Photoshop. Stencil How to launch on ProductHunt Make sure to post your project just after midnight . This way you can be sure to get maximum exposure. Thursdays work well generally. You can also schedule it for the right time a few days in advance. San Francisco time As soon as your post is live on Product Hunt, tell your story in a tweet or even better write a thread about it. Check out this to get a better idea. Tag and maybe some maker friends. Include me , if you like: I'm happy to help with a retweet. Don't forget to include a link to your product page in your thread! example @ProductHunt @spekulatius1984 Welcome everyone into the discussion on your PH post and respond to comments as they come in. Don't forget to upvote the comments as well. Every bit helps you drive more attention to it. Same goes for Twitter. It might become a long and exciting day! What to avoid when launching on ProductHunt Don't ask for upvotes, it's against the rules and you just annoy people. You can hint on it by saying stuff like "Thanks for checking it out and your support!". That's plenty. Don't spam everyone you know with your ProductHunt link. Post it and mention you appreciate support - that's plenty already. Don't try buying fake upvotes or anything like this. It will be noticed and you'll ruin your image permanently. Don't launch and run away: You need to be responsive and engage with the community. Passive launches fail regularly. Examples of ProductHunt launches I've launched a few times with different results. Mostly my projects reach a few hundred upvotes and receive a few thousand visitors.

How to Launch on ProductHunt

Manual Or Automatic Testing? The software is invariably created by people, tested by people and, in most cases, used by people. The worst dream of any responsible tester is to miss a serious bug. The tester tries carefully examines the requirements and writes test cases, carefully checks the product, and after the release, the user reports a critical problem within a week. How many bugs that are obvious to others are missing? And, maybe, it's time to work only with automatic testers? Automatic testers or QA Automated tests catch errors earlier, preventing them from ever being deployed. They offer a faster feedback loop for programmers because they do not need to go through each path in their application manually. A well-written test can take milliseconds, and with a good development setup, you don’t even have to leave your editor. If you compare this with the manual approach a hundred times a day, you can save a good chunk of time. This allows developers to more quickly implement functions since they can confidently write code without opening a browser. When applications grow without a reliable test suite, frequent errors silently penetrate their code. And as the application grows, the overall solution is to scale the number of hands on the deck — hiring specialized testers (QA), which will never be as effective as automated tests in trapping regressions. QA increases the time it takes to implement features because developers must communicate with each other with another person. Compared to a set of tests, it's expensive. This does not mean that QA is absolutely useless, but they should be hired in addition to a good test suite, and not as a replacement. Although hand-held testers are not as effective as computers when searching for regressions, they are much better at testing the subjective qualities of software, such as user interfaces. Types of Tests Let's look at the different types of tests. At one end is unit tests. These tests isolate individual components, proving that they provide the expected behavior regardless of the surrounding system. Because of this, unit tests are usually small and fast. In the real world, these components do not exist in a vacuum: they must interact with each other. One component can expect a collaborator to have a specific interface if, in fact, he has a completely different one. Despite the fact that all tests pass, the software as a whole is broken. Here are the integration tests. These tests use the system as a whole, rather than its individual components. They usually do this by simulating a user trying to complete a task in software. Instead of accessing call methods or collaborators calls, integration tests relate to clicking and typing as a user. The best way to create your own test set, using a combination of tests. This is a suite that contains several high-level integration tests that cover the overall functionality of the application, several middle-level tests that cover the subsystem in more detail, and many unit tests to cover the details of each component. This approach corresponds to the strength of each type of test when trying to minimize their disadvantages, for example, a slow execution time. Development process stages Test Driven Development Process Automated tests are probably the best way to gain confidence in a growing code base. To increase this confidence and achieve big gains in time saving and clean code, it is recommended to write code using a process called Test Driven Development. TDD is a process that uses tests to develop designs and applications. It starts with the Red, Green, Refactor development cycle. Red, Green, Refactor is a series of steps that lead to the development of this function or the correction of an error. When solving problems with TDD, you need to decide where to start testing the code. Starting from a high level, checking how the user interacts with the system, and then turn to zero? Or start with a low-level development and move towards the final function? The answer will vary from person to person and function to function. If a test is originally written, it does not mean that test development is used. When performing a Red, Green, Refactor cycle, it is important to write code only in response to error messages that result from testing failures. This ensures that functions that are not tested will not be implemented. Behavior Driven Development Process The software development methodology Behavior Driven Development is an offshoot from Test Driven Development. The main idea of this methodology is to combine in the process of developing purely technical interests and business interests, thereby allowing management staff and programmers to speak the same language. For communication between these sides, natural language constructs understandable to a non-expert is used, such as admin panels, registration forms that usually express the behavior of a software product and the expected results. The BDD methodology is an extension of TDD in the sense that before writing any test, you must first describe the desired result of the added functionality in a subject-oriented language. After this is done, the constructions of this language are translated by experts or special software into the test description. Domain Driven Design BDD can also be described as the intersection between Domain-Driven Design (DDD) and TDD. Domain-Driven design is an approach to software development aiming to deal with projects with complex business rules where collaboration between developers and domain experts (typically, this role is assumed by the client) is necessary to set a common language and a domain model that can be translated into very specific and detailed requirements. In BDD, these specific requirements are used to drive the development process in the first step of its cycle. From business to tech testing process What Do Our Guys Use For Testing? For our team, testing is first and foremost a good tone rule. We created our own set of tools and applications and didn’t give up on manual testing at all, which in our opinion is considered optimal in the work of each IT company. Let's review the tools we have chosen for testing. 1. RSPEC To verify Ruby code, use a tool written in Ruby RSpec. This is a behavior-based development environment (BDD) and writing sufficient code (TDD). The entire work of the Amoniac team aimed at the clarity of development and the satisfaction of the end customer. That is why We selected RSpec because we consider it the best and most effective tool in our testing work. 2. TURNIP Turnip is an open source Ruby gem that provides a platform for acceptance tests and aims to solve some of the issues faced when writing specifications with Cucumber. Cucumber supports various programming languages and is also very popular as an acceptance testing framework. Turnip works like Cucumber as it is a framework that primarily supports acceptance testing. Although Turnip is not as feature-rich as Cucumber, it is simple and powerful, which makes acceptance testing easier and more accessible. 3. FACTORY BOT Factory Bot is a helper for writing factories for Ruby tests. It was previously known as Factory Girl. For older versions, use FactoryGirl instead of FactoryBot. This library is used to conveniently create instances of models, something on which we will test. For example, some Users, and Articles, and Projects, and with Task. We cannot create objects every time by filling in all required fields. This is where the Factory Bot will come in handy. It is enough to define a pattern once and then generate new entities based on it. 4. VCR Approach for preventing external requests is to record a live interaction and ‘replay’ it back during tests. The VCR gem has a concept of cassettes which will record your test suites outgoing HTTP requests and then replay them for future test runs. Considerations when using VCR: Communication on how cassettes are shared with other developers. Needs the external service to be available for a first test run. Difficult to simulate errors. The VCR gem is really useful if you have methods that need to make an API request. You don’t want to make API requests during tests, especially if the API has some kind of rate limit. What you could do is create a text file mocking the response you get from the web service you’re making the API to and do the tests that way, or you can use the VCR gem. 5. WEBMOCK WebMock is a library for stubbing HTTP requests and setting expectations on HTTP requests in Ruby. With WebMock, developers can match requests based on method, URI, headers, and body, and match the same headers in different representations. Summary And in the end, we can easily say that yes, testing is a huge lion's share of the time saved as by the developer and as the end client. It is this work that allows you to make exactly the product you see in a head in the end, and this is a guarantee to a client that it works flawlessly. Set of tools are capable of testing in seconds and in this case, writing a test will be a time saving and not vice versa. Writing a test gives error messages, the test that will tell you what to do next. And, perhaps, it looks like a kind of robotization, but with a growing number of projects and their scale, it becomes just a necessity. But should never forget that on the way of testing there can be a significant number of traps and anti-patterns that should be avoided, because a poorly written test can have the opposite effect and lead to a crash. The test gives you confidence that you can move on. Both software and QA could and should be used together to tame existing projects and solve larger and more complex ones!

Effective Testing in Complex Software Development Projects

Using a browser to consume content is something most of us do everyday. Heck, you're doing it right now. Recently though, I was humbled by the realization that for something I do so often, I only had a vague idea of what was happening "under the hood". But rather than stew in my own shame and self-loathing, I decided to dive in to gain a better grasp on the complete end-to-end process, or life cycle, of a browser. While I won't be tackling the complete complexity and hundreds of components that make up a browser, hopefully this quick guide will give you a better understanding of what's happening the next time you navigate to a website. Request Preparation Most often a browser's journey begins with a , or, as it's more commonly referred to as, a URL. Put simply a URL is an address. Put a little less simply a URL is a specific type of (URI) which is a sequence of character that identifies a resource, and, for our purposes, a website. Diving a bit deeper you'll find that the URL structure is surprisingly robust as it contains: Uniform Resource Locator Uniform Resource Identifier : the (network) method of access to the resource. Protocol : the address where the resources can be accessed, these are often used in place of an IP address because they're easier to remember. Domain : a more precise location for accessing specific resources. Path : where parameters and values are stored. Query string : an internal page reference, commonly referred to as an anchor. Fragment Once you've entered a URL into the address bar and struck the enter key the browser gets to work! The Power of DNS Domain names are useful because they help us more easily remember the address for content, like web sites/pages, we want to consume. Computers, however, don't use domain names to communicate, they use (IP) addresses. Internet Protocol So, steps must be taken to use the domain name to find the associated IP address. This process is known as the (DNS) lookup. Domain Name System The lookups are initially performed through use of a . Root servers contain mapping information between domains and their corresponding IP addresses. Though the number of root servers is in flux there are several hundred located around the world. root server Pretty straight forward, right? Efficient? Not really. As you can imagine it takes time to communicate with root servers, and for data, like domain/IP mapping, that doesn't change often so it makes sense to cache this kind of information. That's not to say that a DNS lookup takes a long time, but it's faster to check cache. DNS information can be cached at four levels: Browser Cache Operating System (OS) CacheRouter Cache Internet Service Provider (ISP) Cache The browser will start by searching its own cache. If that doesn't exist then the cache stored by the OS will be checked. In fact, this process of checking will continue using the router then the ISP. If the information cannot be found at any of the cache levels then a search will be conducted using the root servers previously mentioned. Request and Response After successfully locating the IP address the browser is ready to make a request for data. It's important to note that from this point forward we'll be looking at a (HTTP) request workflow. Hyper Text Transfer Protocol : While HTTP isn't the only type of request browsers support, it is a very common activity that will provide a good foundation of knowledge to expand in subsequent blog posts. Note The client sends a request to open a connection via (TCP) . 1. Transmission Control Protocol synchronize (SYN) packet The server accepts the connection and responds to the client with a TCP SYN . 2. acknowledge (ACK) packet Having successfully established a connection with the server, the client prepares and sends an HTTP request header that includes information like the HTTP method, path, cookies, and a variety of other details. 3. Sample request header The server receives the HTTP request and begins preparing a packet containing the HTTP response header along with a part of the requested content. There are a variety of content types that can be returned. You can find more information on them . 4. here Sample (HTML) response header Steps and show how the process can be repeated on an established connection. It's important to point out that establishing a new connection can be a time-consuming process and crucial to re-use already opened connections as much as possible. 5 6 Just the beginning When a response from the server has been received the content is then handed off to the layout/rendering engine of the browser. There are a variety of rendering engines but they are all tasked with the same mission; to display information on the screen. While there is certainly more to unpack (see what I did there?) when it comes to the browser rendering from a workflow perspective, that's it! The complete, high level, journey of requesting information from a web server. Keep an eye out for future write-ups where I'll be diving deeper into the details of other types of requests (e.g. HTTPS), how browser layout engines work, and more!

There and Back Again: A Browser's Tale, Part 1

Just about everyone who has tried to make radically healthier changes to their have realized that this is easier to accomplish with some kind of support system aside from your own will to succeed. It is a great help for people to cheer you on, support you, give you advice, or even criticize you on your way to better eating and overall health. daily food consumption Sometimes, you just can’t trust yourself as you are prone to self-rationalization (you are the best person to convince yourself to do anything), and an external perspective can be very useful. We live in an age that a community can be in touch with one another, regardless of where they are physically. Health and fitness communities span countries, or even continents; they can share recipes, compare notes, and keep tabs on each other’s progress. Despite the widespread contagion of contaminated food, and genetic concoctions supposedly for human consumption, and strains of resistant bacteria, there has never been a better time in human history to sculpt the healthiest human beings ever to walk the planet. questionable chemical It is because of the availability of massive information, along with the tools to acquire even more, as well as the ability to transmit this data all over the globe that we have no more excuses in creating the best manual to human health and wellness. We don’t have to rely on static, low quality and outdated pictures on printed media; the Internet provides rich and updated audiovisuals to keep us educated and motivated to seek the best foods to consume. Along with great imagery and recipes, we’ll also be motivated and interactively connected with fellow healthy foodies as we make our way eating the right foods at the right amounts, and the right ways to prepare them. Rich media cuts both ways, however. You will also be exposed to the culture of food that has caused this unhealthiness in humanity.

Project "Carpool" "Carpool" is a simple desktop application, that generates carpooling table from worker time schedules and car ownership information. Workers who has same work location and shift, should drive together to workplace. The company has over 100 workers and carpool table was created manually. The client wants to automate this process. And here I am: Motivated, Excited and Cheap Mistake 1. Adding features Do not add "nice to have" features. Do not suggest any new features and functionalities to client. If client requests new feature, just say: "Let us finish this core functionality and then add new features" After 2 month the Client wanted to persist, edit, delete and update workers in the Application. The data should has been saved in the cloud and accessible from every device. Now it is no more simple desktop application but a Software as a Service (SaaS) with high complexity. This changed everything and my focus shifted from what Client really needed to what was possible to implement. Mistake 2. Starting with backend Never start programming backend, before Frontend. Even better do not program backend at all, take service like Firebase to persist you data. I started writing simple CRUD Microservice for workers. But it did not end there, I added Keycloak for Authentication, added pipelines to automate deployment, configured NGNIX to redirect requests, used docker compose to wrap services and create network between them, added SSL Certificate to Homepage. After we spent a lot of time doing DevOps (Operations), we moved to Firebase. All that great programming work was just waste of time (sad). Firebase provided all resources we needed. It took only 1 week to adapt Web App to Firebase. Just WOW! Mistake 3. Rare communication with a customer Give weekly feedback to your customer, even if he does not explicitly ask for it. A simple E-Mail is enough. It also serves as your progress documentation. As our Project grew more and more complex, we had less and less time for anything except programming or so we thought. Even "small" features, like adding avatar to worker took 4 dev days. I really regret not communicating it to the customer. Our hard work were unnoticed. Mistake 4. Not having a plan Bad plan is better than no plan. Create stories, create tasks, create milestones. We started with no plan, then we wrote our tasks in Excel Sheet :D, then we started using Jira. Jira worked best for us. We created a lot of Tasks and it was frightening how much work was to do. Then we started working on tasks, delivering very slowly feature after feature. Mistake 5. Not having WebApp mock Before you start working on web app, create a UI Mock or draw the UI on the paper. I explained to my business partner what I want to have but he always delivered something else. Then I started drawing on Paper and saving them as part of a task. It improved the communication and quality of the work enormous. Mistake 6. Overpromising, underdelivering Underpromise, overdeliver! Conclusion In the end our client did not want us to continue to work on the project anymore. We lost a lot of time and trust of our client.

What I Learn When I Failed a Project

If you are training to be a hard table tennis professional player, you have to invest in a ping pong robot. This can help to build your form and skill and are simply great for any level of players. These robots can be simple or sophisticated but their primary aim is to make you perfect your game. With these, you can improve your style of the game and also build your consistency. As for the price factor, do not consider purchasing an expensive one if you are just a casual player. Most of the machines are designed with pre-programmed practice drills that help you recover your weaknesses. Without any further delay, let’s get into the best robots you can find in the market. JT-A Robot This robot is specially engineered for the beginners, the intermediate players, and those who want to refine their game. Installed with auto ball feeding, it is a two motor head robot that has a ball frequency of 30 to 100 balls per minute. JT-A-Robot can carry 200 balls per session and it can work with 42 types of spin. This can also do a combination of spins and can land randomly. As per the remote control, it has a remote control which is wired and an A/C supply. This is a wonderful robot but due to poor marketing, it has lesser visibility than the other robots in the market. This robot can promise 3 years of the warranty period. Oukei TW-2700-S9 This robot is priced on the higher end side and it displays features in the same way. It has independent dual heads and offers the best training experience. Designed for the intermediate or the advanced trainers, this has a ball frequency of 30-100 balls per minute. With the ability to have 99 custom drills, this can get the best out of you with a ball speed between5-50 meter/ second. There is random ball placement and it has wired remote control. This robot can throw the ball randomly at 18 locations with different spins every time. It completely justified its price as the outer parts are also well built. It is an intelligent pre-programmed robot and if you are an experienced player, you should have it. Butterfly Amicus Professional This can be called as the best overall robot in the table tennis practice gear. If you are wondering what you can do with this robot, here are the features of this hotshot: This robot is packed into a compact machine that can be easy to move around and transport. This isn't like the other robots but it has 3 various launch wheels that can help to produce whichever kind of spin in a single drill. It can do actions like the backspin, the sidespin, etc. or This robot can be programmed to perform some of the best exercises you can come up with and there are few in built programmed drills already in this robot that you can start training right away with. It can carry a memory of 99 exercises that can be enough even for a lot of advanced players and every exercise drill can have up to 8 steps which are a lot of exercise for the player. If at all you want a better robot performance, you can turn on the RND mode which shoots the balls from your drill and within an area of 20 cm area. After you feel that you have mastered this drill, you can turn on this mode again so that you can practice once more. This robot also has a ball recycling system where you can continue to train without having to pick the ball again and again because this robot will refill itself. There can be a lot of cost-effective robots out in the market but this one here really outshines itself. iPong V300 If you want to start with an inexpensive option, you have the least expensive ones like the iPong V300. They are very practical and they are quite handy now that they have a wireless remote. When they are out of the box, this robot is in three pieces but they fit together quite perfectly. Transportation is quick and can fit anywhere. The wireless remote can do much more than that, it can allow you to tame the ball speed or the spin type. This robot can also shoot the balls alternatively so that it can force you to move and make it realistic and worthwhile. This robot is inexpensive which comes under $200. It has the capacity of the 100 balls and the maximum speed of 90 balls. The best thing about this robot is that it can help you improve your aim and are effective at what they do. If you are a beginner, then you should own this robot as they help you to improve your strokes and then repeat continuously. It is a challenge to find a robot this cheap and highly effective for your game. Newgy Robo-Pong 1040 If you want to own a robot, then you should own a portable one. It is a simple, easy robot that can be deployed. All you have to do is to is unbox the robot, plug it in, and start using it. This is also equipped with a 15-minute intense training session module and you can calibrate the control box from which it controls the speed, the oscillations, and other such options. You can improve your footwork and perfect those tricky shots which can get you out. Though it doesn’t have a lot of features, it is still worth its money and is a steal.

It doesn’t matter if you are just a novice or an advanced table tennis player, it will help you perfect your technique. Prices of each robot may vary but they all help in developing your game. Find the perfect one from one of the above robots that might be of some help.

Top 5 Ping Pong Robots: 2022 Edition

These dreams go on when I close my eyes Every second of the night I live another life These dreams that sleep when it’s cold outside Every moment I’m awake the further I’m away This is the chorus of one of my favorite songs from when I was a teenager. by Heart. Even though the song was released in January 1986, I still occasionally listen to it now. These Dreams (Check out the music . In 3 minutes and 48 seconds, it encapsulates everything you need to know about the 1980s. The sound. The attitude. The hair.) video And yet, there is something about the lyrics. It isn’t clear what they mean, or if they even “mean” anything. But I like this idea: I can interpret the words any way I like without worrying too much about what the songwriter intended. And, for me, this lyric captures the essence of dreams. At least, how I experienced them. It is about the fragility of our aspirations. One moment, we have it all figured it out. The next, our dream has eluded us and “all we remember are the dreams in the mist,” to refer to another line I like from the song. Dreaming Then All of us, especially when we are young, dream of what we want to be when we “grow up.” Me? In the winter, I dreamt of being a professional soccer player. People are cheering my name. Adrenaline. Fame. Fortune. I have it all. During the summer, I was a professional cyclist. Or, an unbeatable Formula One driver. It reflected what was on TV. And, from time to time, I dreamt of being a rock star. I flew the world on epic concert tours and visited lavish lounges with people waiting in line to ask for an autograph. I always loved my dreams when I was a kid. Daydreaming while listening to music, such as Heart, was one of my favorite activities. I was an only child and had the freedom to go wherever my mind would take me. And like most young people, then and now, I guess — my dreams were fleeting. They were constantly changing, depending on what was hot. It was a world of relatively few, static, role models. Soccer player. Cyclist. Rock Star. My dreams were my neighbor’s dreams. The essence of every dream was to feel that you had accomplished something meaningful and that you were admired. Dreams all involved the adulation of large appreciative crowds. But, for most of us, living our dreams was impossible — a fantasy. And pursuing our dreams probably wasn’t smart either. Whenever I listen to now, I think of the dreams of my youth. I am not a professional soccer player, a cyclist or a rock star. I never was. And yet, what has returned recently is this feeling of looking to the future and imagining new possibilities. These Dreams Dreaming Now Right now, things are changing. We are witnessing a “reset” in the world. The adoption of technology was accelerating anyway, but coronavirus has disrupted everything and accelerated the future. With governments lifting lockdowns and re-starting economies again, I see many people expecting or hoping that things will go back to normal. But the question is whether this scenario is realistic. No matter what you think of the pandemic, it will change the way we live, work, and play. The health crisis will have a much wider impact than we initially anticipated. We realize that we can’t ignore potential “pandemic” threats in the future. Personal hygiene and “social distance” will remain critical components of everyday life for the foreseeable future. Material things and appearances become less important in a “working from home” environment. Comfort trumps fashion. Role models are quickly changing. The keywords of the future are “reopening,” “restarting,” and “reinventing.” At least, I see these words everywhere right now. It’s all part of this huge global reset. We must all find motivation from the fact that the world is changing. It’s time for all of us to “wake up.” And part of that is to re-imagine our dreams. The dreams of my childhood seem weird in a post-corona world. It’s like telling a friend that you have always dreamt of being a Greek philosopher or a Viking. When will we see packed stadiums again? Will it ever be appealing to be a professional athlete or rock star without being the center of attention, surrounded by the roar of the crowd? The current health crisis has consigned many of our dreams to history. New opportunities are emerging. And, perhaps most importantly, the distinction between the world of our dreams and the real world of actual possibilities has become blurred. Finding Your “Dream” In the real world, work will change. There are several reasons. Jobs will disappear. The economic downturn will force businesses to reduce costs and cost-reductions will inevitably lead to fewer jobs. The crisis will force businesses to transform and in times of transformation jobs will become obsolete. Other jobs will significantly change. Businesses will have to look for new opportunities with different job requirements. New jobs will emerge. The change in work is illustrative of the “next normal.” Uncertainty and continuous change. Many people must re-start with a blank page. This isn’t easy and there are many structural barriers to overcome. Living your dreams, knowing what is right for you, and when you should settle, has given a new meaning. It’s less about dreams and more about seizing new opportunities. Finding and living your “dream” is the next normal. How? Self-learning! Self-learning is more crucial than ever. You have to continually find what is right and adapt to new situations without the existence of predefined roles and role models. Learning to live in uncertainty. You must spend more time consuming, creating, and correcting content (and I am not only talking about social media). Learning to be creative. Because exploring, experimenting, and sharing are essential components of self-learning, you have to learn to love the process. Learning to love the process. Life has always been a never-ending process of learning. What is different now is that a premium has been put on self-learning and defining your next reality. Nobody can do that for you. Nobody can predict the future. Self-learning and finding your own way are essential to be better prepared for the fast-changing future. The opportunity to live your dream has never been more real.
