Sat, 04 Sep 2010 21:19:54 +0000 http://backend.userland.com/rss092 en We have been really crap at communicating the next scikit-learn coding sprint. It's next week! The coding sprint will take place the 8 and 9 September at INRIA Saclay, near Paris, in the room K110 (building K). For those who cannot make it, it will be possible to participate using the IRC ... http://gael-varoquaux.info/blog/?p=139 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 ... http://gael-varoquaux.info/blog/?p=138 No point me launching in a rant against Git, it's the future anyhow... but it's the only DVCS that I know with which I routinely loose work, and it is called a feature (I lost work a few times with bzr, but these were bugs)! http://gael-varoquaux.info/blog/?p=137 I have just spent the best part of my Sunday fixing a bug that turned out being a seemingly-trivial two-liner. Such unpleasant experiences are all too frequent, and weight a lot on my view of code design. My stance on code design I call code design the process of designing the architecture ... http://gael-varoquaux.info/blog/?p=136 We are organizing a coding sprint in Paris on the scikit learn, machine learning in Python. The goal of this sprint is to set the API and the general coding guidelines of the scikit to be able to tackle many different statistical learning problems in a consistent framework. This is why ... http://gael-varoquaux.info/blog/?p=135 A signature pattern There are many libraries around to specify what I call a 'signature' for an object, in other words a list of attributes that define its parameter set. I have heavily used Enthought's Traits library for this purpose, but the concept is fairly general and can be found ... http://gael-varoquaux.info/blog/?p=134 Euroscipy 2010, the third European conference for the use of Python in science, is just over, and I think it was a great success. Euroscipy in numbers The attendance this year was huge: there was a grand total of 160 who came to EuroScipy, with 140 that came only to the tutorials, ... http://gael-varoquaux.info/blog/?p=133 Given that we have been able to turn on registration only very late, the EuroScipy conference committee is extending the deadline for abstract submission for the 2010 EuroScipy conference. On Thursday May 20th, at midnight Samoa time, we will turn off the abstract submission on the conference site. Up to then, ... http://gael-varoquaux.info/blog/?p=132 The registration for EuroScipy is finally open. To register, go to the website, create an account, and you will see a 'register to the conference' button on the left. Follow it to a page which presents a 'shoping cart'. Simply submitting this information registers you to the conference, and on the ... http://gael-varoquaux.info/blog/?p=131 It is still not possible to register for the Euroscipy conference: we are having difficulties with payment for the registration, and we are still not sure that we will be able to actually charge money! This might not be a bad news, because it might mean that the conference will be ... http://gael-varoquaux.info/blog/?p=130
