SVG Word map of countries

To be able to visualize some quantities attached to countries all over the world, I needed a image with various countries color-coded. The fantastic matplotlib basemap package was not an option as I really needed a static image.

So I generated an SVG image with all the countries. It was generating by tracing a bitmap, so [...]

General relativity, quantum physics, freely-falling planes and Bayesian statistics

We’re famous: the work that concluded my PhD is now picked up by the press http://www.physorg.com/news179481148.html
I hadn’t realized before reading this journalist’s version of the story, but we have all the proper buzz words:

general relativity
quantum physics
freely-falling planes
Bayesian statistics.

This kind of stuff makes great headlines, but the way we are judged on this “success” is [...]

Acceleration estimation in atom-interferometric tests of the Einstein equivalence principle

Hurray! The pivot article that marks my transition from physics to statistic modeling is finally out:
How to estimate the differential acceleration in a two-species atom interferometer to test the equivalence principle
G Varoquaux, R A Nyman, R Geiger, P Cheinet, A Landragin and P Bouyer
To put things in context, at the end of my PhD, we [...]

Frank Willison on the French

I couldn’t help myself, this Franck-Willison quote is brilliant:
“And the Europeans accept chaos and know how to live with it. I came away from France believing in the strong faith of the French people, not because of their magnificent cathedrals, but because I saw them drive around L’Arc du Triomphe. As they careened around this [...]

LinuxMag special edition on Python

The French LinuxMag just published a special edition on Python, in which I authored a 12-page article on scientific computing. The edition is in French, so if you don’t speak French, it is of limited interested.

Ce dossier hors-série est une excellente ressource pour découvrir Python, entre autre par ce qu’il présente Python sous beaucoup d’aspects [...]

George Orwell and Kafka… about our Justice and Law Enforcement

We used to park our car in a calm neighborhood a few blocks away from our place, as there where always empty spots.
In January of this year, our car was picked up by the police because we had left it parked for more than a week (actually more than two). I was amazed to find [...]

My travels this summer

This summer has been hectic (life is hectic anyhow!). As I was switching fields from physics to neuro-imaging, I took the chance to travel to the US and to spend the summer doing Python-related stuff.
Austin - Enthought
I spent most of my time this summer at Enthought, in Austin, Texas. Actually it was the Enthought guys [...]

My computer wants a break

Hell, I had a crazy summer of hacking (it not quite over yet, and I really need to blog about it). I am starting too feel a bit tired, but apparently my laptop feels even more so.
My DELL laptop has decided it would die on me: it no longer charges. The good news is that [...]

Rendering static pages with Turbogears

Yes, the topic of this post is a bit unlike what I usually talk about. But, hey, a man’s got to do what a man’s got to do.
Turbogears hack
So, suppose you have a dynamic website using turbogears, and you want to publish part of the content of this dynamic site to a static website, for [...]
