[sage-devel] Re: SAGE notebook 2

2007-06-23 Thread Hamptonio

Nils Bruin has addressed most of the points I was going to make, but I
did notice one minor thing in testing the new notebook - it actually
effects the old one too:

If you have a comment with a question mark, the question mark gets
parsed by the help system.  I consider this undesirable behavior.  For
example, the line

# Is this a bug?

has output:

No object 'sh.bug' currently defined.

...which certainly isn't what I would expect.

Cheers,
Marshall Hampton

 Hi,

 I spent the last 3 days synthesizing the ideas from the workshop and writing
 a lot of code and have put together the first version of the SAGE Notebook 
 2.
 I've posted a server running it here:

https://sage.math.washington.edu:8102/

 Unless anybody *else* wants to put a lot of hard work into this now, it is in
 feature freeze.  I implemented the minimum of what I really wanted.

 I'm sure there are *lots* of bugs in the notebook.  I don't know of any
 in particular, but I wrote a lot of new code, so there are bound to be
 numerous issues.

 I want to use this new notebook server in a class for high school
 students that I'm teaching next week, so I would be very grateful if
 people could try it out and report bugs or points about the design
 that they find very confusing.  You can also report features you wish
 were there, but I'm not going to implement anything new on the notebook
 myself for a while.

 By the way, the general document model greatly resembles Google
 Documents, as I'm sure will be clear once you try the notebook out.

 Important note -- I implemented a secure separate process model for
 the notebook.  Unfortunately, ssh doesn't work at all in the chroot jail
 that the server runs in (Bobby -- why!?  -- just create two new accounts
 with dumb passwords -- it isn't possible to ssh from one to the other),
 so I can't use it in the chroot jail yet.   So it is trivial to vandalize the
 server...

[sage-devel] rubik's cube images

2007-06-23 Thread David Joyner

Hi:
I think I've implemented correctly plotting routines for the Rubik's cube.
Two examples are given at
http://sage.math.washington.edu/home/wdj/expository/ ,
if anyone is interested. They use Tom Boothby's polygon_plot3d code
which he emailed me. (Tom: I hope I am free to use it and add
a GPL blurb to it with your name appropriately added?).
The plan is to have by default, sagemath.org to appear in grey
in the lower right hand corner (which can be cropped out or turned off,
if desired). Any comments on it? Maybe a lighter grey?
It will take awhile to create a patch since it is currently not
implemented as a CubeGroup module method. Maybe by late romorrow.
I was hoping to use Tachyon but I couldn't find some features I needed
so I didn't get
far with it.
- David
