Intermine, where I was tasked with creating new user training documentation. For this project, I entirely rewrote the Intermine user documentation — which included images, code snippets, tables, mathematical formulas, and more — using GitBook. This guide will share my experience creating technical documentation using GitBook and act as a de-facto quick-start guide to GitBook.

What is GitBook?

GitBook is a collaborative documentation tool that allows anyone to document anything—such as products and APIs—and share knowledge through a user-friendly online platform. According to GitBook, “GitBook is a flexible platform for all kinds of content and collaboration.” It provides a single unified workspace for different users to create, manage and share content without using multiple tools. For example:

For many enterprise-grade applications, providing a point where you can access in-depth analysis about your data has become a crucial feature. There are many approaches to this — you can build your own web application and backend that has views allowing customers to filter and analyze data. Alternatively, you can use the embedded analytics capabilities of Looker, Tableau, or Sisense — all of which are large business intelligence tools, with a host of features and connectors into all sorts of data sources.
But if you’re already on AWS, then it really is worth considering QuickSight to present analytics in your web application.

This series will guide you through the intricacies of creating a multi-tenant solution with QuickSight, dealing with data security across customers and within organizations. We’ll need to go beyond to AWS console and dive into the CLI/API commands that you’ll need to manage all of this.

In this article, we will discuss a use case where data from one kafka cluster has to be migrated to another Kafka Cluster. Here the target is strimzi and the source is a standalone Kafka cluster.  Target means where data has to be copied and the source is from where we want to copy/migrate data. I have an article on how to use mirrormaker with apache kafka clusters about mirrormaker version 1. This article is about mirrormaker 2, which has more features than mirrormaker1.

At the time of writing this article, the latest version of strimzi is 0.22.1 and can be downloaded from here.

The idea behind building a mobile app has been to offer a faster, easier, and innovative experience on various devices to users, doing away with their need to browse websites. However, in a bid to stay relevant to consumers amidst competition, companies try to bundle up a million features together rather than offer a full-proof and specific solution for a certain user need. Being overwhelmed with numerous unnecessary features and functionalities, an app poses various inhibitions to a great user experience. In this blog, we will take a look at how a micro-app can help enterprises solve this issue.

What is a Micro-App?

It is a web/mobile-based, a customized app built to enable end-users to perform a certain, narrowed-down function. Unlike a conventional mobile app, which is bundled with multiple features and pages, the micro-app is smaller in size, more consumer-oriented, and built to offer certain functionality, has an easy user interface, with a dynamic loading that bypasses the app store. For instance, a Personal Banking app has several functions, such as viewing the balance, getting mini statements, changing the ATM password, money transfers, etc. However, if you build a micro-app for this, it will accomplish only that specific task, such as getting transaction history.

From dev tools to productivity to a little bit of fun with sudoku, this month’s collection of new tools is packed with something for everyone.

Here’s what new for designers this month.

May’s Top Picks

Am I FLoCed?

Am I FLoCed? Is a tool to see if you are part of a Google Chrome origin trial. It tests a new tracking feature called Federated Learning of Cohorts (FLoC). According to Google, the trial currently affects 0.5% of users in selected regions, including Australia, Brazil, Canada, India, Indonesia, Japan, Mexico, New Zealand, the Philippines, and the United States. The page will try to detect whether you’ve been made a guinea pig in Google’s ad-tech experiment.

According to the designers of Am I FloCed: “FLoC runs in your browser. It uses your browsing history from the past week to assign you to a group with other ‘similar’ people around the world. Each group receives a label, called a FLoC ID, which is supposed to capture meaningful information about your habits and interests. FLoC then displays this label to everyone you interact with on the web. This makes it easier to identify you with browser fingerprinting, and it gives trackers a head start on profiling you.”

Uncut

Uncut is a Libre typeface catalog that just got started in April. It features contemporary typefaces and styles and is set to be updated regularly. Sort by sans serif, serif, monospace, or display typefaces. Plus, you can submit a typeface for inclusion.

WordPress powers nearly 40% of all websites, thanks to its commitment to making publication possible for everyone, for free. Combined with premium plugins and themes, it’s possibly the ultimate tool for building attractive, unique, and feature-rich websites without any coding or design experience.

However, you do pay the price for this experience, with WordPress and its third-party products not always being built for performance – whether it’s page loading times or SEO.

Image optimization is a particularly big concern. Images are one, if not the largest, contributors to page weight, and it’s growing significantly by the year. So, while images are crucial for beautifying your website pages, they are also one of the biggest factors slowing it down.

In terms of image optimization, WordPress+Elementor brings very little to the table. WordPress core now comes with both responsive syntax and lazy-loading. Elementor itself also only comes with responsive syntax out-of-the-box. However, these are baseline techniques for image optimization that will deliver the bare minimum of improvements.

This means that, while Elementor makes it easy to design sweet-looking WordPress pages (with tonnes of creatively utilized images), you will probably pay the price when it comes to performance. But don’t worry. We will show you how to dramatically improve web performance by over 30 points on scoring tools like Google’s PageSpeed Insight

Why Optimize Your Elementor Images with ImageEngine?

In general, image CDNs use various techniques to get image payloads as small as possible and deliver image content faster, all while minimizing the visual impact. ImageEngine is no different in that regard.

Firstly, ImageEngine, when used in auto mode, will apply all of the following optimizations that web performance tools like Google’s PageSpeed Insight recommend. For example:

  • Properly size images – ImageEngine automatically resizes images for optimal size-to-quality ratios depending on the screen size of the user device. ImageEngine supports Retina devices.
  • Efficiently encode images – Applies different rates of compression depending on the PPI of the user devices. For example, ImageEngine adapts and more aggressively compresses on higher PPI devices without losing visual quality.
  • Next-gen format conversion – Automatically converts images to the optimal next-gen format according to the browser, device, or OS. ImageEngine can convert images to WebP or JPEG-2000 as well as GIFs to MP4 or WebP.  AVIF is also available in a manual directive mode.
  • Strip unnecessary metadata

While these features are standard for most image CDNs, ImageEngine is unique for its use of WURFL device detection. This gives ImageEngine much deeper insight into the user device accessing a website page and, by extension, its images. Using the screen size, resolution, PPI, etc., ImageEngine can make more intelligent decisions regarding how to reduce image payloads while maintaining visual quality.

This is why ImageEngine brands itself as an “intelligent, device-aware” image CDN and why it can reduce image payloads by as much as 80% (if not more).

ImageEngine also provides a proprietary CDN service to accelerate image delivery. The CDN consists of 20 globally positioned PoPs with the device-aware logic built-in. This allows you to deliver image content faster in different regions while also serving images straight from the cache with a ~98% hit ratio.

ImageEngine also supports Chrome’s save data setting. If someone has a slow connection or has activated this setting, ImageEngine will automatically compress image payloads even more, to provide a better user experience on slower connections.

How to Use ImageEngine with WordPress and Elementor

If you’re using WordPress and Elementor, then chances are you want to spend as little time on development and other technicalities as possible. Luckily, ImageEngine is a highly streamlined tool that requires little to no effort to integrate or maintain with a WordPress site.

Assuming you already have a WordPress website with Elementor, here are the step-by-step instructions to use ImageEngine:

  1. Go to ImageEngine.io and sign up for a 30-day free trial.
  2. Provide ImageEngine with the URL of the website you want to optimize.
  3. Create an account (or sign up with your existing Google, GitHub, or ScientiaMobile account).
  4. Provide ImageEngine with the current origin where your images are served from. If you upload images to your WordPress website as usual, then that means providing your WordPress website address again.
  5. Finally, ImageEngine will generate an ImageEngine delivery address for you from where your optimized images will be served. This typically takes the form of: {randomstring}.cdn.imgeng.in. You can change the delivery address to something more meaningful from the dashboard, such as myimages.cdn.imgeng.in.

Now, to set up ImageEngine on your WordPress website:

  1. Go to the WordPress dashboard and head to Plugins -> Add New.
  2. Search for the “Image CDN” plugin by ImageEngine. When you find it, install and activate the plugin.

  1. Go to Settings -> Image CDN. OK, so this is the ImageEngine plugin dashboard. To configure it, all you need to do is:

a. Copy the delivery address you got from ImageEngine above and paste it in the “Delivery Address” field.

b. Tick the “Enable ImageEngine” box.

That’s literally it. All images that you use on your WordPress/Elementor pages should now be served via the ImageEngine CDN already optimized. 

ImageEngine is largely a “set-it-and-forget-it” tool. It will provide the best results in auto mode with no user input. However, you can override some of ImageEngine’s settings from the dashboard or by using URL directives to manipulate images.

For example, you can resize an image to 300 px width and convert it to WebP by changing the src attribute like this:

<img src="https://myimages.cdn.imgeng.in/wp-content/uploads/2021/03/banner-logo.png?imgeng=/w_300/f_webp">

However, use this only when necessary, as doing so will limit ImageEngine’s adaptability under different conditions.

What Improvement Can You Expect?

Let’s see what results you can expect from using an image CDN to improve your page loading times.

For this, I created two identical WordPress pages using the Elementor theme. The one page purely relied on WordPress and Elementor, while I installed and set up ImageEngine for the other. The page had some galleries as well as full-size images:

The pages used many high-quality images, as you might expect to find on a professional photography gallery, photography blog, stock photo website, large e-commerce site, etc. I then ran page performance tests using Chrome’s built-in Lighthouse audit tool, choosing scores representing the average results I got for each page.

For thoroughness, I tested both the mobile and desktop performance. However, I focused on the mobile results as these showcase more of the image CDN’s responsive capabilities. Mobile traffic also accounts for the majority share of internet traffic and seems to be the focus for search engines going forward.

So, first of all, let’s see the mobile score for the page without ImageEngine:

As you can see, there was definitely a struggle to deliver the huge amount of image content. Google has shown that 53% of mobile users abandon a page that takes more than 3s to load. So, clearly, this page has major concerns when it comes to user experience and retaining traffic.

The desktop version fared much better, although it still left much to be desired:

When digging into the reasons behind the slowdown, we can identify the following problems:

Most of the issues related somehow to the size and weight of the images. As you can see, Lighthouse identified a 3.8 MB payload while the total image payload of the entire page was close to 40 MB.

Now, let’s see what kind of improvement ImageEngine can make to these issues by looking at the mobile score first:

So, as you can see, a major improvement of 30 points over the standard WordPress/Elementor page. The time to load images was cut down by roughly 80% across the key core web vital metrics, such as FCP, LCP, and the overall Speed Index.

In fact, we just reached that critical 3s milestone for the FCP (the largest element on the visible area of the page when it initially loads), which creates the impression that the page has finished loading and will help you retain a lot of mobile traffic.

The desktop score was also much higher, and there was further improvement across the key performance metrics.

If we look at the performance problems still present, we see that images are almost completely removed as a concern. We also managed to bring down the initial 3.8 MB payload to around 1.46 MB, which is a ~62% reduction:

An unfortunate side effect of using WordPress and WordPress plugins is that you will almost inevitably face a performance hit due to all the additional JavaScript and CSS. This is part of the reason why we didn’t see even larger improvements. That’s the price you pay for the convenience of using these tools.

That being said, the more images you have on your pages, and the larger their sizes, the more significant the improvement will be.

It’s also worth noting that lazy-loaded images were loaded markedly faster with ImageEngine if you quickly scroll down the page, again making for an improved user experience.

Thanks to its intelligent image compression, there was also no visible loss in image quality, as you can see from this comparison:

Conclusion

So, as you can see, we can achieve significant performance improvements on image-heavy websites by using the ImageEngine image CDN, despite inherent performance issues using a CMS. This will translate to happier users, better search engine rankings, and an overall more successful website.

The best part is that ImageEngine stays true to the key principles of WordPress. You don’t have to worry about any of the nuts and bolts on the inside. And, ImageEngine will automatically adjust automation strategies as needed, future-proofing you against having to occasionally rework images for optimization.

Spring and fresh designs are in the air. This month, it’s obvious that designers are feeling creative with new and interesting concepts that range from a new style for cards, homepage experimentation with multiple entry points or calls to action, and risky typography options.

Here’s what’s trending in design this month.

1. “Flat” Cards

Card-style design elements that allow users to click through to other content aren’t new, but the design of these cards is fresh and interesting.

Rather than more heavily designed cards with shadows and layers of content, flat styles are trending. Expect this trend to explode thanks to usage by Google for a shopping experience page.

The Google example below is interesting because Google’s Material Design guidelines are what helped card-style elements grow in popularity previously. However, those cards did include more layers, color options, buttons inside the cards, and shadows.

Today’s trending cards are completely flat. And beautiful.

Each of these websites does it in a slightly different way.

Heartcore, a consumer technology VC company, uses a series of flat cards as a navigation element to help users find their way through the website. Each features a bright color background with an illustration and a simple text block.

Each card has a nice hover state where only the illustration zooms inside the card frame. This is an interesting effect because it is exactly the opposite of the previous iteration of cards, which zoomed the entire card as a hover state.

Google Shopping uses that whole card bounce hover state (plus a not-so-flat shadow) for each card. The initial design is sleek with the pairing of white and image cards with simple text in each. You are enticed to click around to see what happens.

Click on Greece is a travel website design that uses simple cards with a minimal color and text overlay. The consistency of these cards makes the design pop and the beauty of the images draw you in. Each card also has a hover state with a darker color mask to guide navigation and make text elements easier to read.

2. Multiple Homepage Entry Points

For a long time, designers have been working off the philosophy that the homepage should have one direct entry point, creating a direct funnel for the user experience.

These designs throw that idea out the window, with multiple entry points and click elements.

You can think of it as the “create your own adventure” option for these designs.

It can be a risky concept if you are diving into analytics to pay attention to user paths. You want to make sure you know what choices users are making so that you can help them on the journey to the content and information that you want them to get from the visit.

But this type of design scheme does feel somewhat personalized, putting the user in more control.

Parcouse Epicuriens uses three flat card-style elements to help users pick what they want to see from the home page. There’s no other button or direct call to action, which is somewhat uncommon in today’s website design landscape. Users have to pick from one of the cards, scroll, or enter using the hamburger menu icon.

Tasty Find uses search options to help users start their journey. What’s interesting here are the choices – search for the food you want, pick something random, or (in the small print) find even more options. Users get three choices to begin their journey with the website.

What’s interesting is how simple this complex user journey looks. The design is easy to digest, but so many options could overwhelm users. This is one of those situations where you have to watch return search data and information and weigh the risk versus the reward of so much choice. It’ll be interesting to watch this design over time and see if the options decrease in number.

Accord also has several levels of user engagement opportunity. Option 1: Every block contains a click element. Option 2: Use the search at the top to narrow choices. This is an interesting configuration as the homepage for an e-commerce website because they get right to product selection and shopping without a softer sell or introduction.

3. Risky Typography

Typographic risk has been an ongoing theme for a little while. Designers are embracing experimental and novelty typefaces to stand out in the cluttered website space. Sometimes it works beautifully, and other times, it can fall short.

Here, each of these trending website designs uses a risky typography treatment. The risks are a little different for each design, from readability to comprehension to font delivery.

How Many Plants has duel typography risks: A funky typeface paired with odd word breaks. Interestingly enough, readability isn’t as big of a concern as you might think. This is likely because there aren’t many words, and they are short. Plus, the imagery ties in nicely.

Do you notice a similarity between How Many Plants and The Great Lake? The typography has the same style with a blocky, slab, sans serif with alternating thick and thin strokes. (It’s the same font.)

The risk in the typography design for The Great Lake isn’t in the homepage display, although you might wonder what the design is about. It is carrying this font throughout the design. While it looks great large and with only a few words, it gets a little more difficult the more you see it. This type of mental reading weight can be difficult for visitors over time, creating an element of risk.

Zmaslo uses an interesting typeface with a liquid effect on top of an unusual word. That combination of text elements makes you think hard to read the homepage, despite its neat looks. The risk here is weighing visual interest against comprehension. Depending on the audience, this risk can be worth the chance.

Conclusion

Spring always seems to be that time of year where designers start thinking about new, fresh design elements. That might explain some of the “riskier” design choices and experimentation here.

Regardless of the motivation, it is always fun to see the creative stretch happen. It can be even more interesting to see what elements from these trends continue to grow in the coming months.
