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 …
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 …
Ondrej Certik has installed a sage notebook on a server opened to the net, with Mayavi installed on it. The result is that you have a command line interface on the web, in which you can enter Mayavi commands, and see the result. You have to be very careful to …
I have been wanting to change slightly the design of a Mayavi dialog for a while. Here is the issue: when you create a visualization, eg throught the command line in IPython, whith mlab, you get a nice and small window with only your visualization, and a toolbar. If you …
There is an error in a code example in my article that just came out in Linux Magazine France. I am so ashamed. I did test the code, but I didn’t have automated tests, so I broke it when tweaking it :(. I think the lesson is that you need …
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 …
The title of this post is a lure: there won’t be a Mayavi image each week, because I would run out quickly. But it sounded cool.
Anyway, here is an image of a graph, visualized with Mayavi. The graph is actually a protein structure, downloaded from the PDB. The …
When I started working in my new field (data analysis of functional brain images), I was surprised to find in our data-analysis scripts what I thought was a very particular code smell: the numerical code is always doing a lot of filename and path manipulation, loading and saving data even …
Mayavi 3.1.0 has just been released, and I think it is a fantastic version. We are starting to be able to focus on the details and the focus. In addition, we are getting user feedback, which helps identify the pain points.
Automatic scripting
This is a huge deal …
The mayavi manual in SVN has now 120 pages when compiled to pdf. I know that this is a stupid metric, and that the quality is more important then the number of pages, but it does give me a warm and fuzzy feeling.
More seriously, next release of Mayavi (coming …
As promised, here is the sequel to the tutorial I posted yesterday on using Mayavi with scipy to understand the trajectories of a particle in a potential. (chances are you are reading this before my previous post. I suggest you first jump to my previous post, and then come back …
Many years ago, I was working with a bright undergrad on the trajectories of a atoms in a complex light field created by the intersection of two laser beams. She had developped a code in C, and I was starting to discover Python, so we had binded in t in …
David just blogged a link to an article about careers in higher education. I thought the paragraph on the French system was so much to the point that I would like to quote it entirely here:
In France, the access to a first permanent position as maître de conférences occurs …
