report from EuroSciPy 2010

Aug. 6, 2010

Hi, I am back. The conference was very nice, and several things are clear to me now: - sphinx was a good move (thanks, Logan!) - cython is the way to go for speed - writing a GUI with traits and mayavi should not be that difficult for a dedicated person (one guy did a very cool GUI for some brain imaging in six months as his master thesis at EPFL, without prior knowledge of Python...) Check out the conference site [0], all the slides should appear there sooner or later. Also, a very interesting collection of tutorials was assembled, see [1], (or [2] with my scipy.sparse tutorial, to be merged to [1]). r.

new tutorial on interactive use
by Robert Cimrman Aug. 2, 2010

Aug. 2, 2010

Hi, I have just finished the first draft of a tutorial on interactive use. You can get it at our new repository [1]. <get the updates> cd doc make html <view _build/html/index.html> It's called Interactive Example: Linear Elasticity. Unfortunately I can not upload the new generated docs to our site right now, but it should appear soon at [2]. Awaiting feedback, r.

master repository moved to github
by Robert Cimrman July 28, 2010

July 28, 2010

Hi all, as you may have noticed, the link [0] at our downloads page [1] stopped to work as SymPy guys moved their main repository to github (this setup was mostly "historical" anyway). That is why I created 'sfepy' github account, and turned it into organization, which is a cool new github feature for collaborative development, see [2]. Now two things should be done: - write me your github login names if you want to be included in the developers team = have push/pull rights to the new master repository [3] - if you have already a sfepy repo on github, remove it, and fork [3] - forking is cool, this is what github says: "By forking a project instead of cloning, creating a new GitHub repo, and pushing to it, you allow us to create a link between your fork and the original. This link helps us keep you informed of changes to the original codebase and make it trivial for you to notify the originator of changes that you have made and would like have reviewed." Also checkout/explore the sfepy organization page [4], and the dashboard. I am myself just learning about github features so if you have some ideas, post them, please. Best regards, r.
