Programming

If you haven't done any Clojure, may be Elixir?

I like Scala:

• multi-paradigm, you can explore many ways of doing something, within one codebase - arguably the most complex language, if you want, but doesn't have to be: start simply, later scales robustly
• compiles and interoperates with JS, JVM, native
• Scala3 dropped brackets - easily readable like python
• great tooling (recently) - compiler infers so much -> less puzzles / testing
• developed mainly in europe, not controlled by big-tech

Fwiw, here's my interactive climate system model running in pure scala.

COBOL

The languages I've been meaning to learn, and do something "meaningful" in, are:

• nim
• erlang (or whatever is the most sensible modern variant)
• lisp (ditto)

C# is good. I use Visual Studio on Windows, so I'm not familiar with the tooling in VS Code in Linux, but I've heard good things. .NET is a nice environment to work in, the runtime works on all the OSs, and you can even package it into a self-contained binary with a little finagling.

I tried to get into Python, but always found it boring. Ruby was more my speed because it was inspired by Perl and that's the first language I learned. But Python will likely get you more job opportunities.

I think Rust and C# are the future.

Controversial opinion, but I think Python, Java, VB, and others will become legacy languages. They'll be around for 30-60 years, just like Cobol, but I expect things to settle around other languages.

PHP is a really fun language syntactically and has a surprisingly good built-in library.
