SQIP - CLI utility that generates a lighweight preview for a given image in SVG format.

Have you ever seen how Google, Pinterest or Facebook preload their pictures? Say, you open Google and search for a picture, the results appear in grid and each image has its own colored placeholder and only then the real image is loaded replacing the placeholder. It is very nice practice from UX point of view.

The use case of SQIP is pretty simple. Firsly you need to generate the SVG preview:

sqip -o output.svg ../myImage.jpg

then, you calculate base64 from it:

cat output.svg | base64

and now you can use it in your HTML code, something like this:

<img width="600" height="400" src="myImage.jpg" style="background-size: cover; background-image: url(data:image/svg+xml;base64,PHN2ZyB4bWx....0iMjciLz48L2c+PC9zdmc+);">

And here you go!

TeaVM - is quite peculiar web framework. You write the code on Java/Kotlin/Scala and it transforms the code to JavaScript to be run in a browser. It sounds like old-school GWT framework, but the biggest difference is GWT parses Java source code, but TeaVM parses the compiled java byte code. This makes compilation much faster than GWT and it supports the latests features from JVM languages. As author says, the compiled JS is significantly smaller, than on Angular or ReactJS. So, today you can use your favourite Kotlin both on backend and frontend :3

If you have a dozens or even hundreds of microservices and all of them expose their APIs to the rest of the world, you often need to manage the same things for every service separately, such as authentication/authorization, security checks, load balancing and etc... In this case an API Gateway could be useful, becuase it builds sort of "façade" for your APIs and allows to manage all APIs in one place. Here are few open source solutions:

• Kong, has 12,3k stars on GitHub. Build in Lua language on top of Nginx. Provides a lot of ready plugins for security and Auth, rate-limit, caching, logging and etc...
• Tyk, has 2,4k stars on GitHub. Build on Go. Provides many features out-of-the-box, such as web Dashboard, with monitoring, API documentation, Mocks for testing, notifications and many more...
