I use Evernote for this - every time I figure out how to do something I drop it in a note. I create 4-5 notes a day. It's incredibly useful - I find myself referring back to some notes months after the fact.

My team also do standups on Slack, and I've got into the habit of writing detailed Slack stand up bullet points with links to commits, documents I've created and so on - almost a semi-public developer diary. I don't check back to these very often myself, but they do spark some useful conversations.

I've also gotten into the habit of writing extremely details commit messages - often multiple paragraphs for a few lines of code change - that record the background and reasoning that lead me to the change. I do most of my code reading through the GitHub web interface, frequently referring to blame and history, so the more context I can find for historical commits the better.

I hope Evernote is better now. I lost data when it was synchronizing once. It was 5 years ago though.
