I work in Java and Kotlin still. I miss doing OCaml. I miss writing C. I am trying to keep my sanity by doing Erlang[1] (gonna be our server for various purposes and I did not want to use Go because I thought it would be a great opportunity to perfect Erlang) and reading old books on Forth. I am also reading "Fundamentals of Embedded Software: Where C and Assembly Meet". For the foreseeable future I will do more designing and reading than implementing, but I will be toying around of course; for example right now I am doing hot upgrades and release handling in Erlang so I will not hesitate much due to ignorance when the time comes. This is just a minor part of it, of course.

In any case, Java, and especially Kotlin are quite tolerable with IntelliJ. It is a great IDE for those two at least. Plus I get paid, which is also a motivator... :D

[1] Truth be told, it is difficult to keep that sanity because I dislike the OTP documentation. I am reading books instead. I already know what their "target_system" does anyway, I modified it a lot for my use case but I reverted it because I thought it would be more of a hassle in the end.
