[sage-support] Update SAGE: sws files lost!

2008-06-29 Thread Rolandb
A huge dissatisfier for the third time .. I update VMARE (to version 2.04) and thereafter SAGE (from 3.0 to 3.0.3). This is the third time I lost all my notebook files (sws) ... How can this be avoided!! Please help, because many days of work are now 'lost'. Thanks in advance. Roland

I don't use the vmware version, but you should be able to save sws files somewhere else on your system as a backup, from the notebook. -M. Hampton On Jun 29, 2:57 pm, mabshoff [EMAIL PROTECTED] dortmund.de wrote: On Jun 29, 12:52 pm, Rolandb [EMAIL PROTECTED] wrote: Hi, A huge

[sage-support] Circle demo yields an ellipse!

2008-06-29 Thread Owen
The first example here: http://www.sagemath.org/doc/html/tut/node21.html .. shows creating a circle plot via: L = [[cos(pi*i/100),sin(pi*i/100)] for i in range(200)] p = polygon(L, rgbcolor=(1,1,0)) p.save() ## or p.show() When I try this, I get an ellipse! Or more precisely, the

Good catch. Maybe the documentation should be updated to use p.show(aspect_ratio=1) ? On Sun, Jun 29, 2008 at 5:31 PM, Owen [EMAIL PROTECTED] wrote: The first example here: http://www.sagemath.org/doc/html/tut/node21.html .. shows creating a circle plot via: L =

[sage-support] Mac: Should Sage use Frameworks?

2008-06-29 Thread Owen
(BTW: Thanks for the *fast* response to my Circle question earlier!) This is a more general question: should Sage or other large systems use the Mac frameworks on Macs? Or more generally, shared libraries on other systems/distros? I ask because I recently downloaded GRASS, a large GIS system.
