I love to say that Python is a nice subset of Lisp, and I discover that it's getting even more true as time passes. Recently, I've stumbled upon the PEP 443 that describes a way to dispatch generic functions, in a way that looks like what CLOS, the Common Lisp Object System, provides.
I've been hacking on Python for a lot of years now, on various project. For the last two years, I've beenheavily involved in OpenStack, which makes an heavy usage of Python.
Once you start working with a hundred of hackers, on several software and libraries representing more than half a million source lines of Python, things change. The scalability, testing and deployment problems inherent to a cloud platform meddle with everything in designing components.
Doing code reviews is a great way to discover things that people might struggle to comprehend. While proof-reading OpenStack patches recently, I spotted that people were not using correctly the various decorators Python provides for methods. So here's my attempt at providing me a link to send them to in my next code reviews. :-)

This service provides a simple storage service for applications using RESTful interfaces, providing maximum data availability and storage capacity.
I explain here how some parts of the storage and replication in Swift works, and show some of its current limitations.
If you don't know Swift and want to read a more "shallow" overview first, you can read John Dickinson's Swift Tech Overview.
