Two years ago I started working on SourceForge with a couple of python developers. Back then the site was written in PHP and was in some ways buried in technical debt. Everything is different today, we have a complete set of tools for Ticket tracking, Wiki documents, Git, Mercurial, Subversion, and IRC -- all written in Python, and now released as open source software.

This is the story of how the amazing libraries, tools, and talent in the Python web community has radically changed an established company, and allowed us to reinvent sourceforge.net.

This talk will go over our tech stack, talk about the libraries we used, the way we solved scalability, internationalization, and performance issues issues. Ultimately we know that without python, we could not have built a flexible plugin based system, and gotten permission from management to open source it.

In todays world, nobody (should) deploy a web application facing the
internet without having a proper caching system in place. There are
many different solutions to choose from, from manual use of memcached
through framework integrated caching to external caches like Squid or
Varnish. Most modern frameworks come with integrated functionality for
at least one of these methods, and often more than one.

However, they often relies on all traffic going through the same
framework to work properly - a caching layer in Rails is hard to share
with one in Django. This talk will show a way to break the design
rules of these frameworks just a little, and have the database help
solve this problem.

This talk will use a small application written in Python using Django
to illustrate the examples, but the method is language independent.
Unsurprisingly, the database used is PostgreSQL.
