George Peristerakis: How openstack automated the software development process.

The Openstack system is a collection of open source services that helps you setup a cloud infrastructure. It is also one of the largest and most active code base. I will talk about how openstack automated most of its development process.

**David Taylor: Top 10 'Python idioms it took me way too long to figure out **

(http://www.prooffreader.com/)

Since I adopted Python after learning programming in Visual Basic, I gradually found out features that, had I known them before, would have saved me from having to reinvent the wheel, like collections.Counter, dict.get(), list.enumerate(), etc.

**Stéphane Guidoin: CKAN plateforme de données ouvertes en python: forces et défis **

(http://nordouvert.ca/)

Lancé par l'Open Knowledge Foundation et développé en Python, CKAN a vocation a servir de portail de données ouvertes, notamment pour les gouvernements. CKAN a acquis une position dominante, surtout auprès des gouvernements nationaux. Malgré cette position, le développement de l'outil n'est pas aussi rapide que beaucoup souhaiteraient et plateformes comme Socrata demeurent très présentes, notamment auprès des municipalités, malgré leur prix nettement supérieur. La présentation couvrira l'architecture technologique de CKAN, ce qui lui a permis de devenir une solution dominante, mais aussi les défis de croissance auxquels fait face ce projet.

**Cameron Davidson-Pilon: What is PySpark and When Should I Use it? **

(http://www.shopify.ca/)

Spark is being called the next generation of Hadoop: it's faster, more accessible and has a large community behind it. PySpark is a Python interface to Spark. In this talk, we'll discuss what MapReduce is, PySparks API, and when to use PySpark versus another tool.
