wtf is jetbrainsruntime-for-linux-x64?

This project provides a custom-built version of the Java runtime environment specifically optimized for Linux computers. Java is a programming language that powers many popular applications, including all of the software made by JetBrains, the company behind widely used developer tools like IntelliJ IDEA and Android Studio. This project takes the official Java runtime created by JetBrains, adds some improvements, and compiles it on a regular schedule so that Linux users always have access to a fresh, optimized version. At a high level, a Java runtime environment is the underlying engine that actually runs Java applications on your computer. The version provided here is tweaked to perform better or include specific patches tailored for Linux systems. Because the project is compiled on a set schedule, it automatically picks up the latest changes and fixes from the source code. This means users can download a ready-to-use package without needing to build the complex software themselves from scratch. The primary audience for this project is developers or anyone using Linux who runs JetBrains software and wants the best possible performance. For example, if you are running IntelliJ IDEA on a Linux machine and notice it could be faster or smoother, you could swap out the standard Java engine it uses for this custom one. It is meant for people who want the cutting-edge improvements of the runtime without the hassle of compiling code. The README does not go into detail about the specific improvements made to the runtime or the technical build process. However, the core concept is straightforward: it is an automated pipeline that delivers an enhanced Java engine for Linux users. By compiling it regularly online, the project removes the technical barrier for people who want the optimizations but do not want to maintain their own build environment.
