Although I often have embarrasingly parallel problems (data parallel), and I have an 8-CPU box at work, I used to frown on writing parallel computing code when doing exploratory coding. We now have fantastic parallel computing facilities in Python (amongst other, multiprocessing, IPython, and parallel Python). However, in my opinion …
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 …
Next year’s EuroScipy will be in Paris, as Nicolas Chauvat and myself announced in Leipzig this summer. We are still busy organizing, but we have pretty much settled down for a dates: July 8th- July 11th. So mark those dates, and get ready to come to Paris for a …
How to test functions that use the numpy random number generator
The week is over, and I am finally catching up with things, back here in France.
The SciPy conference was exciting and fun as usual. It was great to meet old friends and put faces on names on the mailing list.
The turn out was very good: we had 150 …
I gave a presentation on Mayavi in the Python for science seminar organised by Fernando Perez at Berkeley. I was loudmouth and obnoxious as usual, and unfortunately for me, I was recorded.
More seriously, Jeff Teeters has filmed the presentation and recorded the sound was a microphone I was wearing …
The SciPy conference committee is pleased to announce the schedule of the conference:

This year’s program is very rich. In order to limit the number of interesting talks that we had to turn down, we decided to reduce the length of talks. Although this …
I have never sold the rights to the article I published in LinuxMagazine France on scientific computing with Python. So I am uploading it to the net, under a CC-by-SA license : http://hal.inria.fr/hal-00776672/
It is in French, so it restricts the audience.
The notes of the tutorial I gave on scientific use of Python at PyconFR are online. They are in French, but I am giving the link here, just in case it is needed:

I find that in object oriented design, there are two kinds of objects:
Greetings,

We are finally opening the registration for the SciPy 2009 conference. It took us time, but the reason is that we made careful budget estimations to bring the registration cost down.
We are very happy to announce that this year registration to the conference will be only $150, tutorial $100 …
Fantastic:
Haha - I shake my fuzzywuzzy beard at you in bewilderment. Do you people dislike OOP, the class statement is mere boilerplate to you, I mumble incoherent French obscenities in your general direction. (Did you know the French acronym for object-oriented programming is POO?).
Our lab is seeking to hire an engineer to work on porting our machine learning code to the scikit learn, adding tests and documentation and packaging it.
We are looking for someone motivated by quality in software and open source. No prior scientific computing experience is required. You will be …
May 30th and 31st the French Python conference, Pycon FR, will be held at ‘la citée des sciences’, la Villette, in Paris.
The first day, I will be giving a one-hour-long tutorial (in French) on numpy, scipy, and all the Python for Science jazz. On the following day, I will …
Gary Ruben came up with the excellent idea of visualizing the minimum spanning tree of a Delaunay tesselation in addition to Delaunay tessalation itself. After he sent me his code, I spent some times playing with it, because I found out that, with the right choice of visualization parameter, it …
Gary Ruben just asked me if it was possible to retrieve the triangulation information from my previous Delaunay example. Actually the reason I came up with this example is that Emanuelle Gouillart, my partner[*], needed to do Delaunay triangulation on some data. She was kind enough to extract that code …
Tonight I sat down and played a bit with VTK’s Delaunay tessalation filter. I wanted to inspect the local structure of a graph created by Delaunay tessalation of random points. To see better the structure, I selected a slab of the resulting unstructured grid. I think the image is …
For those who don’t know, sys.path is the path that the Python interpreter traverse at each module import to look for the module file imported.
This blog post is about the consequences of having a long sys.path. I’ll try and make it short, but I would …
Prabhu and I can’t decide: what is best for the documentation, have more pages, and thus have them be small, or have longer pages, but have less. Two specific examples:
