Hyper implies web, and lambda implies function – Hence, Hyperlambda translates into "web functions", and this is a fairly accurate description. However, hyper also implies "super fast", and by super fast here, I mean super fast! 1 minute and 45 seconds was what I needed to create CRUD endpoints wrapping my database table, manually creating my endpoints in the following video, while explaining how I did it simultaneously.

According to modern studies in the subject, the number of lines of code your project consists of, is directly proportional to the amount of energy and resources you’ll need to spend maintaining it. Hence, the fewer lines of code, the fewer resources are required to maintain it. In the video above, I copy and paste 50 lines of code, and I end up with 4 HTTP REST CRUD endpoints. Comparing this to C# is arguably unfair. Simply the boiler plate code for my Controller, would probably end up exceeding this number. You can find my code for all endpoints below.

In this time of global economic turmoil, it’s more important than it’s ever been that your financial decisions are based on accurate, up-to-date, market information.

In a world where stock price is a key confidence marker, the businesses that attract attention, secure investment, and grow, are the ones that can demonstrate their value in a wider market.

Up to now, displaying accurate market pricing has been prohibitively expensive, needing direct access to a huge dataset, and the code to mine it. So we’re delighted to introduce marketstack, a real-time market data API that’s reliable, simple to integrate with your site or app, is lightning fast, and includes a free-forever plan.

What is marketstack?

marketstack is a REST API that allows you to access stock data for public companies at 72 global exchanges including the New York Stock Exchange, the Nasdaq, the Tokyo Stock Exchange, and the London Stock Exchange.

marketstack delivers real-time market data, accurate to a single minute, ensuring that the information you base your decisions on, and the information you pass on to your customers, is always up to date.

There are more than 125,000 stock tickers, from over 50 different countries; you can query stocks, or over 75 different market indices; intraday market data is included, meaning you can monitor trades that close at the end of the day; you can even retrieve data about time-zones and international currencies.

Why Choose marketstack

marketstack uses cutting-edge technology to deliver market data in an easy-to-integrate JSON format, which is lightweight and incredibly easy to dig into.

Requests are made via a simple HTTP GET call, and all requests are run through bank-quality 256-bit HTTPS encryption. Whatever code stack you’re using, whether it’s PHP, Python, Node, or plain old JavaScript, marketstack provides comprehensive documentation to get your team up to speed in mere minutes.

The highly reliable cloud infrastructure can handle anything from a few dozen requests per year, all the way up to millions of requests per day. Regardless of the scale of your project, marketstack is robust and flexible enough to handle it.

It’s Not Just About Money

marketstack isn’t just about the bulls and bears of markets, in the tech sector specifically, stock price is an indicator of wider business trends and performance.

When Apple became the first US company to reach a $2 trillion valuation, not only was its stock price central to the story, but it indicated a trend in the tech giant’s dominance that went beyond cold hard cash.

When an eccentric billionaire makes outrageous, and ill-judged comments, and tanks his company’s valuation, the fluctuations in stock price are a big part of the story.

Beyond the spin of politicians, the market index of different exchanges is an indication of what analysts with in-depth knowledge really think during an election campaign.

With over 30 years of historical data, marketstack is a history of business, particularly the burgeoning tech sector, and makes that history available with a simple to use API.

marketstack’s Rock Solid API

marketstack’s API is built on top of apilayer technology, one of the most respected, and trusted API providers in the world, with a huge amount of experience delivering data reliably. Millions of API requests can be run through the API hourly, and it still has almost 100% uptime.

Any API is only as good as the data it supplies, and marketstack’s data is supplied by numerous high-authority providers around the globe, resulting in unprecedented accuracy.

As a result, marketstack is trusted by over 30,000 companies — including Microsoft, Amazon, Uber, and Credit Suisse — and 80+ universities.

Getting Started with marketstack

marketstack is entirely free for up to 1000 requests per month, with access to 1 year of historical data, as well as end-of-day data. No credit card is required to get started, and you’ll never be billed. This is the perfect option for simple integrations, or developers working on proof-of-concept builds. What we really like about marketstack is that the free package is genuinely usable. It’s not just a trial version that presses you into upgrading.

For anyone who needs more comprehensive data, packages that include market indices, technical support, and commercial use permissions, start at $9.99 per month, or just $7.99 per month when billed annually.

Head over the marketstack today to claim your free API key, and get started.

To understand why user onboarding is such an indispensable tool, we need to empathize with the people using our products; we all come from different backgrounds and cultures, we make different assumptions, and we see the world differently.

User onboarding helps mitigate these differences by making your product’s learning curve less steep.

However, companies often make unfortunate mistakes that hinder user experience and cause frustration. In today’s article, we’ll take a look at eight ways companies ruin their products’ onboarding process.

Let’s dive right in, shall we?

1. No User Onboarding at all

As a part of the team that created a product, you’ve probably spent hundreds of hours going over its features and the most minute detail. Naturally, you know the product like the back of your hand. The user does not.

Naturally, you know the product like the back of your hand. The user does not

We may believe that the app we’ve worked on is straightforward and that user onboarding is probably overkill — but that’s almost never the case. Guiding our users through a product will help with retention, conversion, and their overall satisfaction.

However, there are very rare cases when you can do without user onboarding, here are a few:

  • Your product is too straightforward to cause any confusion;
  • Your product has a formulaic structure, similar to that of other products’ in your category, i.e., social media or e-commerce;
  • Your product relies heavily on Google or iOS design guidelines with common design patterns;
  • Your product is too complex (enterprise or business-oriented) — in such cases, users need special training, rather than just an onboarding;

2. Assuming That Users “Get It”

 One of the vital UX mottos we should always be mindful of is that “we are not our users.” When onboarding them, we always need to assume that they’re at square one. We should communicate with them as if they have no prior knowledge of our product, its terminology, and the way it works.

Providing freshly-registered users with highly contextual information will most likely confuse them. As a result, this will render your attempts to create a helpful onboarding process useless.  

3. Onboarding Users on a Single Touchpoint

it’s tempting to brainstorm which features should make it into the onboarding, then design and code them; that’s a very bad idea

The main problem with the previous point is that it’s too contextual for new users. However, providing no context altogether can be problematic as well. This is commonly found in onboarding processes that focus on a single touchpoint while leaving out the rest of the product.

By choosing to inform users of our product’s features, we force them to detour from their “normal” course of action. This comes at the cost of the user’s frustration.

Since we’re asking people to pay this price, it’s best to provide them with information that will also help them navigate the entire product. As a result, this will decrease the number of times we’ll have to distract them from their ordinary flow.

4. Forcing Users Through Onboarding

We’ve previously mentioned that we mustn’t assume that users have any background knowledge about our products.

The opposite argument can be made — experienced users don’t need a basic onboarding process. It will most likely frustrate them, and it won’t provide them with any real value. Also, forcing users through this process will most likely take the onboarding frustration to a whole other level.

This is why it’s essential that we allow them to skip the parts they don’t find useful. This way, we’ll address the knowledge gaps of the people who really want it and need it.

5. Onboarding Based Purely on Assumptions

This is yet another point that’s implicit in “we are not our users”. Oftentimes, it’s tempting to brainstorm which features should make it into the onboarding, then design and code them; that’s a very bad idea.

Here’s what every designer should do instead:

  • Do user interviews: You should conduct these before having anything designed; user interviews will help you shortlist and prioritize features in terms of their significance, so that the onboarding is focused around the features that matter most.
  • Do usability testing: Once you have a good idea of what features your users consider most important, design onboarding that reflects that; having completed your design, make sure to conduct at least 5 usability testing sessions with users, so that you can make sure that your design works.

6. Just Letting Users Quit

While we shouldn’t force people to go through onboarding, it doesn’t mean we shouldn’t nudge them in the right direction.

find that sweet spot between being front of mind and annoying

People choose not to onboard for many reasons, but showing them around will benefit both parties. Therefore, it’s never wrong to remind them that they can always resume onboarding via email or push notifications (unless you’re too pushy). Make sure to find that sweet spot between being front of mind and annoying. 

Similarly, these two mediums are a great way to deliver valuable information as well.

Here’s a great example of an onboarding email from InVision:

And here’s a clever notification from TripPlanner:

7. Asking For Too Much Information

We need to always be mindful of the fact that the product’s spokesperson should act as a guide during onboarding. Its goal at the very beginning is to build trust.

We can ask for small favors when we’ve built a solid and lasting relationship

Not only is asking for too much information from the get-go unproductive, but it will also undermine the trust that the user already gave us.

It’s best to abstain from asking freshly-registered users for their credit card information. Nearly 100% of businesses care about profits — and there’s no shame in it. However, today’s most successful companies make money by providing users with value. So it’s best to stimulate users to share their financial data in subtler ways while focusing on customer experience.

The same can be said about subjecting the people using your service to extensive questionnaires. At the first steps of our interaction, it’s all about giving and gaining trust. We can ask for small favors when we’ve built a solid and lasting relationship.

8. Onboarding for the Sake of Onboarding

While there are dozens of reasons why you should guide your users through your product, it needs to be done well. A pointless onboarding process that doesn’t provide users with value is more frustrating than the lack thereof.

Onboarding can be a bit frustrating at times. Pointless onboarding will just raise eyebrows. It will slow users down and disengage them, which is exactly the opposite of what we want.

Conclusion

The process of introducing your users to your product is one of the factors that will define its success.

A critical aspect of user onboarding that we need to always take into account is value. Is this detour from our user’s ordinary course of action valuable to them? Will this improve their experience with the product?

Onboarding demands careful and continuous tailoring. Once perfected, this process will help you win new users’ hearts and help you build brand loyalty.

With software products becoming just a bunch of micro-services and third-party APIs mashed together, it’s more crucial than ever to get their structure in order.

GraphQL already did this at its inception by coming up with a whole specification that describes how APIs of its type should behave. In the RESTful API landscape, things were a bit more wild west. However, even if not all backend devs know it, there are a number of specifications for REST APIs as well.

On July 16, 2020, the European Court of Justice got rid of the four-year-old Privacy Shield agreement struck between the U.S. and the EU that had exposed Europeans to possible U.S. surveillance. The agreement had also allowed U.S. companies like Facebook and Google to store data about European residents outside of the region. 

This move is yet another great example of the EU doing “right” by their constituents and holding tech companies responsible for their users’ data privacy. The news also builds on the EU’s General Data Protection Regulation (GDPR) leadership, extending its consumer protections and providing a model for the rest of the world to work from as global data privacy policies continue to evolve.

After six months of uncertainty 2020 is finally beginning to find a style of its own. There are nods to Brutalism, a delightful blending of 80s pastels with 90s primaries, and the font style of choice is anything but geometric sans-serif.

In this month’s collection of the freshest sites from the past four weeks you’ll find tons of new portfolios, from big agencies to freelancers, and some amazing primal scream therapy. Enjoy!

Looks Like You Need Iceland

Looks Like You Need Iceland is an incredible site that asks you to record a scream, that they’ll broadcast for you into the wide open spaces of Iceland as therapy. And then perhaps you’ll visit Iceland for real. It’s brilliant marketing for the Iceland tourist board.

Riverlane

The abstract 3D animation on Riverlane’s site is a stunning introduction to a topic that’s hard to visualize. The rest of the site is equally well done, with great typography, slick brand assets, and a professional engaging tone.

Monokai

Wimer Hazenberg’s site features a simple pixelated text column. But scroll down the page and keep an eye on the awesome text dissolve effect, it transforms this simple design.

I Weigh Community

The I Weigh Community is a non-profit community activism initiative helmed by Jameela Jamil. It’s devoted to radical inclusivity, and it promotes its message on its site with striking graphics and bold, expressive typography.

WAKA WAKA

Waka Waka is a design studio specializing in wooden furniture. The noise effect and the mid-century typography evoke the radical design of 60 years ago. The random rotations on the thumbnail hovers are delightfully disruptive.

Dataveyes

Dataveyes is an information design studio that works with large datasets to give meaning to complex information. Its site features beautiful, full-screen animations that illustrate the type of information it specializes in.

Year & Day

Year & Day is an ecommerce site that sells ceramics, glassware, and other choice pieces of tableware. It’s a colorful collection that perfectly complements your food and the stunning site takes its cues from the collection.

Dunderville

Dunderville is a motion design studio with an impressive portfolio of animation and live action films. Its site features a tactile paper fold detail, and as you would expect, some superb text, and vector animations.

André Venâncio

It’s been months since we last saw a creative developer’s site with a liquid effect. André Venâncio revisits the idea with a cool oil bubble effect, hover over the thumbnails to see it.

Thomas Prior

It’s not all 60s revivalism, pastels, and cute animations. There will always be room for minimalism, and nothing suits this style as well as portfolios for photographers; Thomas Prior’s site is a prime example.

Serra

Serra’s site features a really beautiful high-contrast typeface that sits apart from the usual sans-serif. The product page is all colored product photography. It exudes luxury and distinction in a saturated marketplace.

VYBES

VYBES is a CBD drink made in LA. Its site evokes the Californian spirit with baby pink brand colors and sun-bleached photography. It’s a cool, and ever so slightly Brutalist look for what is essentially a health drink.

Karina Sirqueira

We love the simplicity of Karina Sirqueira’s portfolio. The desaturated rainbow leads to a simple slideshow of projects, and it’s refreshing to see a minimal site that uses bold serif-based typography. The content feels fresh and honest too.

Smalls

Smalls produces healthy food for cats. The site, is packed with adorable pictures of kitties, which if you’re a cat person, is guaranteed to draw you in. There’s a definite Brutalist style to the site, and lots of color too.

Wildist

There’s a clear aesthetic beginning to emerge in 2020, with pastels creating a soft background for desaturated primaries, and Wildist gets it exactly right with this youthful, site that features just enough animation to bring it to life.

Kristen Kwong

We’ve seen a lot of OS-style sites recently, but Kristen Kwong’s is one of the slickest. It manages to take a simple metaphor for interaction and transform it with a vintage color scheme.

Stojo

Continuing the Miami-meets-Brutalism trend this month is the site for Stojo, a collapsable cup and bottle. The pastel shades block out a disrupted grid, but for our money it works better on mobile. The vintage typeface is a nice touch.

Hoang Nguyen

Hoang Nguyen’s site features a surreal 3D scene with mountains, a spinning planet, floating islands, a waterfall, and a floating dragon-boy. Click around the site and the scene transforms.

SMTH / Sam Smith

Sam Smith’s portfolio has a cool magazine style to it, with a nice blocky background on the text and a personality packed animated avatar taking centre stage.

Then I Met You

Then I met You is a site promoting a range of skincare products. In this case, the usual pastel colors are replaced with an 80s-style gradient. Watch the products as you scroll, the lighting changes creating an awesome, subtle 3D effect.

Contentful; Webster’s Dictionary defines “contentful” as… not found. Clearly someone made up this word, but that is not necessarily a bad thing.

The world of user experience metrics is moving quickly, so new terminology is needed. Largest Contentful Paint (LCP) is one of a number of metrics measuring the render time of content on a web page.

What is Largest Contentful Paint?

Google defines LCP as “the render time of the largest content element visible within the viewport.” For what we are talking about in this blog, we will consider “content” to be an image, typically a JPEG or PNG file. In most cases, “largest” points to a hero image that is “above the fold” and is one of the first images people will notice when loading the page. Applying optimization to this largest content is critical to improving LCP.

It is probably more instructive to view LCP relative to other metrics. For example, First Contentful Paint (FCP) and Visually Complete book end LCP.

Each metric has its pros and cons, but LCP is a happy medium. LCP marks when web page loading starts to have a substantial impact on user experience.

In Google’s opinion, to provide a good user experience, LCP should occur within 2.5 seconds of when the page first starts loading. Poor values are anything greater than 4 seconds.

How Does Largest Contentful Paint Impact Lighthouse Scores and SEO?

LCP is now part of several “Core Web Vitals” scores that Google will measure in its ranking algorithm. Each of the Core Web Vitals represents a distinct facet of the user experience, is measurable in the field, and reflects the real-world experience of a critical user-centric outcome.

In the case of the overall Google Lighthouse score, LCP represents 25% weighting on the performance score of Lighthouse version 6.0. This makes LCP the most important Core Web Vitals metric in determining the performance score.

While Google has indicated that content is still the most important factor in SEO ranking, a better user experience (as measured by Core Web Vitals) will generate higher rankings in a crowded field. If there are many websites competing for the top search engine spots, then Largest Contentful Paint will play a critical factor in rankings.

How to Improve Largest Contentful Paint

Now that you know that LCP is important, what can you do to improve it by making content load faster? Google provides a number of suggestions, but the most effective technique is to optimize content for the device requesting it.

For example, a website includes an 800kb JPEG image that is intended for high resolution desktops. On a smartphone, that would be optimized down to less than 100kb, with no perceptible impact on quality. LCP can improve by more than 60% — or several seconds — through this single optimization.

Find Savings in Largest Contentful Paint by using Image Speed Test

Image Speed Test is a great tool offered by ImageEngine.io that provides an analysis of LCP improvement opportunities. Just paste in the URL of the web page you are interested in optimizing, and the test will show you:

  • Image Payload Reduction
  • Speed Index
  • Largest Contentful Paint
  • Page Load Time (Visually Complete)

It also provides a video of the web page loading with and without optimizations. Finally, it analyses each image to provide an estimate of payload savings. In this case, the “largest content” on the page is this image. With optimizations, the image payload is reduced by 94%. That delivers a huge improvement in LCP.

How Does ImageEngine Improve LCP

ImageEngine is an image content delivery network (CDN) service that makes image optimization simple. Basically, for each image on the page, the image CDN will:

  1. Detect the device model requesting the web page;
  2. Optimize the image in terms of size, compression, image format;
  3. Deliver via a CDN edge server that is geographically closest to the user.

ImageEngine improves web performance for every image on the page, including the largest. You can learn more about ImageEngine here, and also sign up for a free trial.

Best Practices: Preconnect

In addition to using an image CDN like ImageEngine, a few other best practices can improve LCP. Using the resource hints to provide a preconnect for your content can streamline the download process.

For example, putting the following link statement in the HTML will accelerate the download process. The link statement will make the browser connect to the third party as early as possible so that download can start sooner. ImageEngine’s optimizations make each image download smaller and faster, but preconnect save time in the connection phase.

Best Practices: Minimize Blocking JavaScript and CSS

When JavaScript or CSS is “blocking” it means that the browser needs to parse and execute CSS and JavaScript in order to paint the final state of the page in the viewport.

Any website today relies heavily on both JavaScript and CSS, which means that it is almost impossible to avoid some render blocking resources. On a general note: be careful with what kind of CSS and JavaScript is referenced inside the <head> element. Make sure that only the strictly necessary resources are loaded in <head>. The rest can be deferred or loaded asynchronously.

When looking to improve the LCP specifically, there are some practices worth looking into more deeply.

Inline Critical CSS

It is not an easy task, but if the browser can avoid making a request to get the CSS needed to render the critical part of the page – usually the “above the fold” part – the LCP is likely to occur earlier. Also you will avoid content shifting around and maybe even a Flash of Unstyled Content (FOUC).

The critical CSS — the CSS needed by the browser to set up the structure and important styles of the part of the page shown above the fold — should in-inlined. This inlined CSS may also refer to background images, which of course should also be served by an Image CDN.

Do Not Use JavaScript to (lazy) Load Images

Many modern browsers natively support lazy loading, without the use of JavaScript. Because images usually are heavily involved in the performance of LCP, it is best practice to leave image loading to the browser and avoid adding JavaScript in order to lazy load images.

Lazy loading driven by JavaScript will add additional latency if the browser first has to load and parse JavaScript, then wait for it to execute, and then render images. This practice will also break the pre-parser in the browser.

If an image CDN is used to optimize images, then the benefits of lazy loading become much smaller. Especially large hero images that are above the fold have a large impact on LCP and will not benefit from being lazy loaded with JavaScript. It is best not to make JavaScript a blocking issue for rendering images, but rather rely on the browser’s own ability to select which images should be lazy loaded.

I must have seen dozens of implementations of this exact same web app during my 25 years as an Enterprise developer. And to be honest with you, I’m tired of implementing the exact same app, over and over again. "Don’t reinvent the wheel" comes to mind. Hence, I decided I wanted to create a "micro service web app", providing me with all translation features I could possibly need in the future. And more interestingly, I will create the entire app, in 1 second, by simply clicking a button. If you don’t believe me, feel free to watch the following YouTube video, where I demonstrate how I solve all my translations needs, for the rest of my life, in 1 second.
