What programming languages and OS platforms are responsible for a majority (say, 80%) of people's incomes here? Doesn't need to be a laundry list of everything you know or work on. I can go first, with possibly the most unfashionable set of programming tools. 😀 I work in C and assembly with a sprinkling of shell scripting and bad python, everything on Linux.

Kotlin/Android for me.

Linux, Ruby, Rails, HTML(everything that outputs to HTML ultimately), JS

JS

Python (For the web)

Ruby, Rails, MacOS

Python

Go/Python/Shell/Linux

JS and Linux

Java / Ruby on rails / Python / Linux

Mac + Javascript, HTML. CSS

Ruby/Rails/JS !

Ruby, SQL, Python, and YAML at the moment. But it's English, a non-programming language, that is my primary tool right now.

Java and its frameworks, Linux, Shell

It is interesting how unimportant the Microsoft platform has become compared to 10 years ago. Of course, this is a small sample size, but I've noticed this trend among other groups too.

@helpful-gigabyte-47939 I have been a .Net Dev for most of my life. First remote gig was in .Net - but very few startup companies - which are more open to remote work prefer MS stuff. You are looking at mostly enterprise - and then things like being a US / UK resident matter. It's a pity though cause it is very productive framework.
