lya Grigorik : Don't "Push" Your Pull Requests

https://www.igvita.com/2011/12/19/dont-push-your-pull-requests/

There is nothing more frustrating than to read the threads, or even worse, be on the receiving end of this experience gone wrong. The contributor is wounded because they are not recognized, and the maintainer is caught in a dilemma: they want to build and foster their community, but they have to dig-in against their biggest fans. There is no winner here and neither side is to blame.
Next time, before you dive into the editor, open a discussion, outline your problem and solution, and offer to do the work - don't "push" the pull request, and don't work in the dark.

InfoQ: Getting to Know Graal, the New Java JIT Compiler

https://www.infoq.com/articles/Graal-Java-JIT-Compiler
Oracle recently announced the first release of GraalVM, a research project that may in time lead to a replacement for HotSpot in its entirety.
For Java developers, Graal can be thought of as several separate but connected projects - it is a new JIT compiler for HotSpot, and also a new polyglot virtual machine. We will refer to the JIT compiler as Graal and the new VM as GraalVM.
The overall aim of the Graal effort is a rethinking of how compilation works for Java (and in the case of GraalVM for other languages as well).
