[sage-devel] Functional derivative consistent with current .diff( )

[ManDay]

I'd like to be able to derive in the following manner:

x = var( "x" );
J = function( "g",x );
f = function( "f",g );

# like so

x1 = var( "x1" );

f.diff( J( x1 ) );

which is the functional f derivate with respect to the value of J at x1. Is 
this possible in a fashion at least similar to what I demonstrate above? I'm 
not understanding enough of the internal workings of symbolic expressions to 
modify "diff" so that it would do what I suggest, perhaps someone has a clever 
idea.

Thanks.

How slow do you mean? It takes me two days to build a bdist for sage...

That's pretty slow, isn't it? Perhaps the Skynet machine can do it in
one day, but still, I doubt the usefulness.


Well, first: I was discussing an ARM bdist ; I was definitely not clear 
about that!


And then it's slow because I have to:
- start compiling with export MAKE="make -j 3 -k" ;
- look regularly to see when it starts compiling m4rie
- kill the m4rie compilation (kill -9  on the conversion.c 
compilation) [note: the -k makes sure everything not needing m4rie is 
compiled before this failure stops the compilation process]
- at that point, kill the gui and as many things as possible to free 
ram, export MAKE="make" and relaunch the compilation, which takes care 
of m4rie. Do that before going to bed!
- kill the compilation wherever it is on wake up (that is, if it is 
finished with m4rie) ;

- restart the gui and the various processes ;
- export MAKE="make -j 3" and finish the build.

I long to see the next m4rie and the next atlas in sage, since both have 
been made much easier to compile in general, and on ARM in particular.

[sage-devel] help vs. ?

[Volker Braun]

Can somebody explain to me why "help(x)" is totally different from "x?" aka 
"%pinfo x"?  I mean, I understand the mechanics but is there anybody who 
likes the current behavior? Shouldn't help() return the same as %pinfo?

This sounds reasonable, I'll change the directory on the download mirrors.

Yes, the "huge" category is correct, that's the only one which is not

I'm in favour of that, this page hasn't been maintained at all – it's

[sage-devel] Two small typos in the reference manual

Hello sage-devel,

Here is my first post to this list:

Included in the attached patch file are two documentation typos I found 
in the reference manual:
* 
http://www.sagemath.org/doc/reference/interfaces/sage/interfaces/gap.html misses 
a "G" for "GAP".
* 
http://www.sagemath.org/doc/reference/categories/sage/categories/weyl_groups.html 
links to a Wikipedia article that does not exist, it should be 
http://en.wikipedia.org/wiki/Weyl_group


Sage is a great system, and I hope to have some more contributions to it 
in the future.


Best regards,
TB
