Syncless is an experimental, lightweight, non-blocking (asynchronous) client and server socket network communication library implemented in Stackless Python 2.6. It contains an asynchronous DNS resolver (using dnspython) and an HTTP server capable of serving WSGI applications. It aims to be a coroutine-based alternative of event-driven networking engines (such as Twisted and FriendFeed's Tornado). It is already about that fast, but it has fewer features and is less stable now.
katso is a library to score binary-categorized data: [low for anti-conformist data], [mean for conformist data], and [high for eclectic data: data that is quite normal (has a lot in common with other data but has a few unusual attributes)]. Data looks like (0, 0, 1, 0, 0, 1, 1) or like (1, 0, 0, 0, 0, 1, 0), all of the same size and corresponding to predefined criteria.
