I have a "notes" directory in dropbox. I use .md files, with a text editor that does some highlighting based upon the markdown. 95% of them go into what I call my "dev diary". Each day gets a new file. Any questions, answers, thoughts, etc. while programming or designing go in there. For searchability, I also add any reference Jira/Trello/etc ids. Beyond that, I have cheatsheets and checklists. Cheatsheets are short, useful things (e.g. commands, undocumented gotchas, etc.) for a given piece of tech. E.g. I have a git.txt, mysql.txt, etc. Checklists are things I should go over whenever I do X. Am I about to commit something? Well, there's a list of things I tend to forget to do. So I have a checklist for this. Each project also gets a file (or folder if it grows large enough) in my notes directory. I previously used Evernote. Then Onenote because it was nicer on the surface pro. But I had to abandon Onenote because they don't have a good Linux client. I decided I was going to stop throwing my notes away and just switched to regular files.
