Web sites with source code for hacking
Once in a while people ask me what open source projects could the contribute to?
I can point them to any module on CPAN, but it can be a lot more fun to contribute to a project where the contribution has immediate and visible impact.
I've started to create a list of web sites where the source code is available, and of course that is is written in in Perl. I tried to group them according to the level of activity of the project
and where I could, I also mentioned the framework used for the project.
I got a lot of input from people on Reddit, but I am sure there are plenty of other sites.
Please suggest more sites, or even send me pull requests.
