What do you want to build?
Discussion
Nothing planned... I would probably play with CLI tools or simple GUI apps. I use both windows and Linux. I'm 50, its not for career, just something I always wanted to do.
Python or JavaScript I would say, but I'm 100% Linux. If you are somewhat technically inclined, the language itself doesn't matter that much, high level concepts you learn in one language can be used in other languages as well.
Thanks for the advice... I was sort of leaning python... thought about c# but I like that python isn't beholdent to any corperations.
