subunit
Subunit is a streaming protocol for test results. The protocol is human readable and easily generated and parsed. By design all the components of the protocol conceptually fit into the xUnit TestCase->TestResult interaction.
There’s also an output adapter for nose.
Ansible
Like Chef and Puppet, but doesn’t require clients on nodes while giving the additional power of Chef in client/server mode, which is rather important to me.
Thrift syntax file for Vim
We’re using Thrift at work.
Twig (template engine)
Twig is a port of Jinja to PHP. This will be useful for me so that I can share some email templates between some legacy PHP code that’s being rewritten in Python.
