Yeah, I think it goes into a similar spirit to what you described, in the sense that you keep things in you in a format you can use later in life.

It wasn’t always so orderly. It really started as a bunch of loose directories with different things. I only actually put it under source control recently when I decided to organize it a bit better. I was surprised with the things I found. Some I had forgotten. Like experiments with new libraries, or even trying programming languages.

This is a great idea! I keep a personal journal, in which I also write about work but not to this level of details.

What I do is to have a repository with experiments and other documentation. For example, when I try new programming languages or libraries, I put it there. When I learn new commands or tricks with commands, I put it there. I sometimes just straight write some documentation about something I did or learn and put it in the repository.

The repository is then highly searchable, and it has been vital for my work life. I’ve been keeping it since school times, so it’s well over a decade old.
