I’m the only programmer at the company. It’s a closed source solution for very specific needs. So I only answer to myself and I don’t have a need to explain (to myself) what I did in a particular commit and if I ever need to check the commit history I can just check a particular files history, not going commit by commit. I never said it was personal code. I said “don’t code alone”. I use linux at home, the server hosting the code commits is linux, the scripts listening to new commits are in bash.
