For music enthusiasts who thrive on insider knowledge and detailed music conversation, WhoSampled would be just their cup of tea. It's basically an online community for discovering and discussing sampled music, remixes and cover songs. WhoSampled has partnered with The Echo Nest to provide the WhoSampled API that allows developers to access and integrate its functionality with other applications.
As a developer, good ways to store those often-reused snippets of code that correctly solve a common problem is always useful. Now, there are other solutions to this problem, such as the Snipt API, which I covered previously, but Pastebin.com is the most often used, perhaps because it has beeb the favored place for notes from hacker group LulzSec. Pastebin has a nice, full-featured API, and is simple and free to use, at least at a basic level.
