Whenever I work at a job I have a text file. Each day I write the date, and I use it as both a scratch pad and a log of bugs fixed with their IDs, features implemented, relevant meetings attended, etc. The files tend to be pretty incoherent but very good for searching for relevant keywords and dates.
