I find that one of the most frustrating aspects to software development is finding a solution to a problem, forgetting it, then being faced with the same issue in the future only to forgot how you previously solved it. Or to write a useful bit of code, then on a later project not be able to find this code.
My general question is this: How do you keep track of all the new things you learn each day while programming? Does anyone have a systematic way to capture knowledge and easily and efficiently apply it in the future?
UPDATE: Thanks the for the responses, here’s what you came up with:
Social
- Stackoverflow
- Tumblr
- Evernote
- Blogs/Wikis
Code Repositories
- Github
- Unfuddle
- LaunchPad
- Google Code
Desktop
- Dropbox
- Yojimbo (mac)
- VoodooPad (mac)
- Wikidpad (win)
- Surfulater
Stackoverflow is a good place to start 🙂
Keeping a blog is another thing (here’s mine).
Even Twitter can be useful for this.
There are also a number of “desktop wiki” applications that I find very useful: VoodooPad on the Mac and Wikidpad for Windows.
Finally, if you need to store snippets (or more) of code (that you have the rights to, of course), then there are plenty of source code repositories available now (GitHub, LaunchPad, Google Code or Unfuddle if you want complete control).
