I create "notes" directory on my desktop at work, and each day I start a new text file named $DATE_$JIRATASKNO_$DECRIPTION.txt Whenever I copy-paste stuff that might be useful I leave it there. Stuff like stacktraces, class:line_number when I was searching where something happens, links to webpages related to the task. I was keeping a notepad tab open at all times anyway to keep context when I was doing something (otherwise I forget when I'm back from lunch and have to search again). So this is only making this context permanent and searcheable. Then when I do something 3 months later and get a stacktrace I vaguely remember or other problem that I can imagine what the keyword would be - I just grep in that directory and find all the context needed, including jira task, commits, all related webpages, etc. I also write short free-text notes there, but these are usually very short and less important than the copy-pasted stuff.
