[sage-devel] Re: Creating the (Z/5Z)^2 group in Sage : Hell among groups, parent/elements, Cartesian Products ...

Hi! Not obvious to me either, but documented (under AdditiveAbelianGroup) sage: v=vector((1,1)) sage: G(v) (1,1) defines an element as a sum of multiples of the generators. cheers, Hugh -- You received this message because you are subscribed to the Google Groups "sage-devel" group. To un

[sage-devel] Should sage -b run sage -sync-build to get rid of outdated .py and .pyc files?

Hi! I'm no expert on the way installation and compilation of sage work, so please bear with me as I go a little slowly (and perhaps get things somewhat wrong). When you compile sage, .py/.pyx files from $SAGE_ROOT/devel/sage/ produce .py/.pyc files in $SAGE_ROOT/local/lib/python2.7/site-pac

Re: [sage-devel] Where on earth are you ? (Sage's map of developpers)

I was very surprised that the map was right for me, in that there is a blob in my location. Of course, it is for someone else, who is not actually there. Golam Hossain is now at the Indian Institute of Science Education and Research (IISER) - Kolkata, India. I am where he was (Department of

[sage-devel] wierd behaviour from sagepad.org patchbot

Hi! The sagepad.org patchbot Fedora/17/x86_64/3.4.6-2.fc17.x86_64/sagepad.orgseems to be depressed. It is unhappy with two unrelated tickets I'm involved in (12943, which is trivial, and

Hi! Trying to build 5.0.beta13 on my ubuntu system, I got an error building gcc-4.6.3. This appears to be the part of the log file where something dramatic happens: In file included from /usr/include/stdio.h:28:0, from ../../../src/libgcc/../gcc/tsystem.h:87,

Thanks, David and Jeroen. I haven't used trac that much, and I guess I just hadn't encountered that behaviour before, so I thought it might be related. cheers, Hugh -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage

Twice, today, instead of the page I was expecting, trac produced something like this: Traceback (most recent call last): File "/usr/lib/python2.5/site-packages/Trac-0.11.5-py2.5.egg/trac/web/api.py", line 377, in send_error 'text/html') File "/usr/lib/python2.5/site-packages/Trac-0.11

[sage-devel] Re: Fwd: Request to review Sagemath Beginners Guide

I began work on translating the combinatorics chapter of the French book last summer, after Nicholas Thiéry asked if anyone might be interested in doing so. (I then got busy with other things and haven't finished it, but I am still intending to do so.) If a joint effort comes together to transla
