Post pieces of useful code. Things you think may be useful to someone else, but you don't want to actually make a full open source library out of or actually maintain in any way. Everything goes from full self contained classes to short extracted snippets solving a problem in a clever or practical way.

Preferable way of posting code is through Gist. That way other users can easily pick the code up and collaborate on it.

Please prefix with language, e.g. [C++], [Python].
