I've put this on my todo list for my Oct - Dec notebook coding sprint. > * People were asking if Sage was available in Debian, I said work was being > done : http://wiki.sagemath.org/DebianSAGE Sage had been officially in Debian for a long time. The catch is that it is Sage-3.0.x, so is quite out of date. > * I like to use %timit u = compute(100) in the command line, but this > doesn't work in the notebook.

In the notebook it would be pretty easy to make it so that if you put %timeit at the beginning of a block, then the *whole block* of code is timed, and the running time is reported. I added that to my list. > * I try to do some search in the sage-devel group from its own web page, but > it apparently finds only the very recent messages.

Do we have a control for this? That's very annoying. Fortunately, if you search from here http://groups.google.com/ you can search all groups you are subscribed to, and the search isn't restricted to recent messages.

He should get involved in Sage and be "The Man" for DE's in Sage! Sage doesn't want anything -- it's users like him who want things. By getting involved in Sage, what he wants because what "Sage wants". > * The same somebody likes the idea of defining in Sage object and translate > it from one system to the other.

Because the Sage library is called "sage", i.e., if the above worked, then things like sage: sage.rings.[tab key] to see what's in the sage.rings wouldn't work. > > > I know I have more ideas, but when I don't write them down, I forget them. > So, I will share them later when they come up. I hope you weren't overwhelmed by the sheer number of questions/bugs/etc. you found during the workshop. It can take a strong constitution to watch Sage get "beat up" by 20 people for a couple days :-). > > Au plaisir, > > Sébastien Labbé > PhD Student > LaCIM, UQAM, Montréal > > > > -- William Stein Associate Professor of Mathematics University of Washington http://wstein.org --~--~---------~--~----~------------~-------~--~----~ To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
