Hi Sage-Combinat,
I get an attribute error when ploting a poset. I already created a
ticket for it :
http://trac.sagemath.org/sage_trac/ticket/12351
I know I should ask first but is this a duplicate ticket or known bug?
Cheers,
Sébastien

Salut!
This spring, I am going to stay in Quebec : redaction of the thesis...
Note that we organize a Sage (Combinat) Days in May 7th - 11th 2012 in
Montreal. The official announcement will be made soon.

Hi sage-devel,
If I want to draw a 3d point of size 100 in Sage, I do :

In the ticket #8599 (which needs review), I propose to change
``pointsize`` for ``size`` because I think
No objection. But you need to provide deprecation warnings before
removing any long used things in Sage.
For now, I use the rename_keyword(pointsize='size') so that both
works. I replaced every occurence of pointsize for size in the doc so
that people should forget soon about pointsize. Maybe a

This is the final alpha release of Sage 4.3.3. The next release would
be an rc0. The development version of Sage is now in feature freeze.
Does that mean only ticket solving a defect will be merged into sage
until sage-4.4.1?
The Sage days 20 are beginning on Monday. I think there will be a
I hope 4.3.3 can be out... tomorrow.
How about a Sage 4.3.3.final with #8295 released Sunday Pacific time?
Then one could produce Sage 4.3.4 incorporating changes from Sage Days
20.

I will work twice as much this week to make more patches to be merged
in sage-4.3.4 !!!

Dear sage-devel,
Is there a reason why str are wrapped in \texttt for the latex output?
sage: latex('abcde')
\texttt{abcde}
Moreover, underscores are changed to \_ :
sage: latex('t_i=4^i')
\texttt{t\_i=4^i}
Personally, I don't like it and I wrote a patch that makes latex
behave like identity
I strongly disagree. For any object foo in Sage, latex(foo) is
supposed to produce a version of foo that is suitable for typesetting
within a mathematics environment. For a string, the right thing to
do is use texttt.
Ok, I understand. So maybe you have a different and better solution

Hi,
To me, a year is FAR too short. Mathematica makes a major release about once
every two years, and a semi-major one every 6-12 months. There are plenty of
people using older versions of that. If Sage wants to make a viable

to Mathematica, it needs to keep deprecated

My feeling is that adding the sentence
