Anyone have a good way to re-find utilities or libraries when you need them later?
One of my greatest regrets in life is not using Org mode sooner for notetaking. (My life has been uneventful.)
Just make sure adding items is as seamless as possible (I use a bookmarklet). If there's too much friction adding items, you're less likely to do it.
Also, I'll sometimes add certain keywords/phrases in the "notes" field that match how I anticipate I'll try finding it again.
For example, if a Django app uses redis but only for optional features, I'll still add "redis" to the "notes" field. In six months when I'm trying to remember the project, the only thing I may remember is it featured redis in some capacity. From there, it's pretty easy to find.
