And what about a mouse running on the keyboard ?

Probability of such event seems greater, among users of Sage, no ?

Re: [sage-devel] Re: A new book on Sage, for high school students in Poland

[Andrzej Giniewicz]

Hi.

I noticed book is already there, but Author names were copy-pasted
from position above. This should be "Andrzej Giniewicz and Katarzyna
Zajączkowska" - not "Thorsten Theobald and Sadik Iliman". Also, in
title instead of "ę" there is "\ce" and instead of "ć" there is "ç".
And - the publication year also was copied from post above I believe,
as we are already on the shelves in 2015 :)

If there are some issues with encoding, this is html-encoded title:

"Zrozumie matematyk z pakietem Sage"

and names:

"Andrzej Giniewicz and Katarzyna Zajczkowska"

Thanks,
Andrzej.

[sage-devel] graph_editor() and digraphs

[Jori Mäntysalo]

Does anyone know javascript here? We have graph_editor() that works nicely 
when starting from scratch. (But forgots labels when modifying existing 
graph.)


But there is no way to draw a DIgraph, and it is a little irritating.

I don't think that it should be hard to do. With all plotting code, 
however, you will deal with hundreds of line of codes, tens of 
customization that walk on each other's toes... But you can probably add it 
'easily'.

These days I use g.show(method='js') a lot. I opened a new ticket yesterday 
to enable zooming:

[sage-devel] Options for graph drawing

[Jori Mäntysalo]

See http://trac.sagemath.org/ticket/13827 , specially starting from 
http://trac.sagemath.org/ticket/13827#comment:5


There is no common view of interface for graph plotting function(s). More 
opinions are needed.


 * * *

We do have common view that it should be possible to, for example, set 
shape of vertices one-by-one, as now we can set colors.
