Good news, everybody! All the Python people will shortly converge to town. We will seize the opportunity to invite a broad audience --all of you Pythonistas in town-- to our good old monthly meeting.

We are pleased to join forces with DevOps Montréal to offer a great event.

We will meet at Radialpoint on Bleury street, just a few steps away from Palais des Congrès.

As usual, the meeting extends into an evening at our favourite place, celebrated brewpub Bénélux!

Main presentations:

Joseph Hall from SaltStack: Configuration management - finding the tool to fit your needs

In ye olde days of web, a company might manage a handful of servers, each manually and frequently tuned and re-tuned to the company's needs. Those days are gone. Server farms now dominate, and it is no longer reasonable to manage individual servers by hand. Various configuration management tools have stepped in to help the modern engineer, but which to choose? It is not an easy question, and canned pitches from sales people are unlikely to take into account all of your variables. This talk will attempt to discuss The Big Four objectively, and from what angles they approach the task at hand.

Yannick Gingras from Facebook: Scaling the Facebook Cache Infrastructure with Python

Facebook leverages in-memory data stores extensively. Even though caching is a conceptually simple service, several problems inherent to our scales make the deployment of our in-memory data store particularly interesting and challenging.

Facebook's real time in-memory data store includes two major services: Memcache, a look aside key-value store, and TAO, a read-through and write-through graph aware cache that supports structured queries. Both daemons run on thousands of dedicated servers.

In this talk, I will give an overview of the problems that we face deploying cache services that answer over a billion queries per second while maintaining sub-millisecond response time. I will describe the strategies that we use to mitigate them and since Python is a critical piece of the puzzle, I will highlight some of the areas where we use it. I won't spare you from our war stories and the sense of scale could feel crushing at times but I will do by best to keep it entertaining.

Alex Gaynor from Rackspace: Code Review for Open Source

Code review is fun. This talk will explore the benefits of code review, and a number of different workflows to enable it in both open source and commercial software development.

Special presentation:

Panel: Python 3 adoption and barriers

Python 3.4.0 was just released! Many Python developers are enthusiastic about the cleanups in the language and standard library, but many others suffer from missing features in the Python 2 line. What’s the status of the migration? How are the core developers in tune with the larger community? Invited representatives, including CPython core developer Nick Coghlan and CPython and PyPy core developer Alex Gaynor will share their experience and answer questions from the audience.
