Open Data Hackathon: road accidents


I've participated at an Open Data hackathon organized by the French Minister of the Interior and several open data institutions. Together with Rue89 journalists and an OCTO Web developer, we created in two days an interactive map of all 62,000 road accidents in France in 2012. We used a very rich dataset released by the Minister of the Interior and Etalab.

Scientific Python in the Browser: it's coming!


There is currently a manifest trend in the scientific Python ecosystem: Python is slowly but surely coming to the browser. It's a real challenge, but we're getting there. In this post, I want to give an overview of where we are, and where we're headed.

Back from our first Vispy code camp at ESRF


We had our first official Vispy Code Camp this week. I and the other core developers of Vispy were kindly invited by the European Synchrotron Radiation Facility. We presented our young library to software engineers from the ESRF and other European synchrotron facilities. It was also the occasion for us to make a gentle introduction to modern OpenGL, as many attendees didn't have experience in real-time GPU rendering. We discovered various scientific use cases in need of high-bandwidth, low-latency real-time visualization of big data.

What's wrong with scientific Python?


tl;dr: Although not perfect, Python is today one of the best platforms for scientific computing. It's getting even better everyday thanks to the amazing work of a vibrant and growing community. I reviewed Python's strengths in a previous post. Here, I cover the more sensitive issue of its weaknesses.

Why use Python for scientific computing?


Why use Python for scientific computing? This is a legitimate question. For us, regular Python users, using Python is so natural that we sometimes forget that this choice is not obvious for everyone. Matlab is very widely used in some communities (e.g. experimental biologists) and choosing a different platform requires extensive proselytism. We need to find the right words to convince people that Python is really the future for scientific computing.
