Well, I've started using Google Code together with Mercurial repositories to manage some of the codings I did. Most of them are probably not very useful, but then again, they where useful for me at some point in time and could be a starting point for others. Furthermore, using a Google Code project is a great way of backing up stuff that needs no privacy ;).
My code dump has two repositories so far:
- CMS Made Simple stuff (like plugins, tools etc.), my CMS of choice for small websites.
- Shell Scripts I wrote. Some to integrate with Nautilus, some to be used on the command line
