Public Code Repositories?

dubious9 asks: "Today I was refactoring a parser of mine to use a better implementation of a string searching algorithm. I went to the internet trying to find a good code repository where I might have a chance to find an implementation of a good algorithm, but a cursory glance turned out no clear winners. SourceForge was the best that I could find. Where is the best online repository/library of common and reusable code snippets?" We've tackled this subject a once or twice over the years, is SourceForge really the best answer or are there other options?

Code snippets & Examples

[Gefd]

If your interested in games or not, both FlipCode.com and GameDev.net have alot of reference material for common algorithms.
They aren't exactly repositories as such, but there is alot of code snippets deposited in various sections throughout both sites.

Computer Science Research Search Site

[frosencrantz]

This site (C.S. only directory) is a great resource for finding Computer Science papers (it covers science papers of all types) Source code is sometimes available or available by asking. You might find a paper that helps you decide how to code something yourself.

Once you find a paper that is close to what you want there are ways to surf to similar/related papers.
