Zoom scaled from 20 million to 300 million users virtually over night. What's incredible is from the outside they've shown little in the way of apparent growing pains, though on the inside it's a good bet a lot of craziness is going on. Sure, Zoom has made some design decisions that made sense as a small spunky startup that don't make a lot of sense as a defacto standard, but that's to be expected.

As a Java Developer, we need to cover a lot of scenarios to ensure the quality of our software and catch bugs as soon as possible when introducing a new code. For 99% of all my use cases AssertJ, Junit, Mockito, and Wiremock are sufficient enough do cover the test cases. But for the other use cases, like unit testing info, debug or warn log messages, these frameworks don't help you out.

When I first stumbled on the idea of skeleton screens, thanks to Luke Wroblewski talking about them back in 2013 , I latched onto them pretty quickly. I have never been a fan of progress bars and spinners, and skeleton screens seemed like a smart step in the right direction. For those unfamiliar, a skeleton screen is a method of displaying the outline (skeleton) of the content to come, typically using gray boxes and lines instead of a progress bar while content is loading.

One of the more fundamental rules of building fast websites is to optimise your assets, and where text content such as HTML, CSS, and JS are concerned, we’re talking about compression. The de facto text-compression of the web is Gzip, with around 80% of compressed responses favouring that algorithm, and the remaining 20% use the much newer Brotli. Of course, this total of 100% only measures compressible responses that actually were compressed—there are still many millions of resources that could

Tip: Lazy-load non-critical resources when a user interacts with UI requiring it. Your page may contain code or data for a component or resource that isnt immediately necessary. For example, UI a user doesnt see unless they click or scroll on parts of the page. This can apply to many kinds of first-party code you author, but this also applies to third-party widgets such as video players or chat widgets where you typically need to click a button to display the main interface.
