notebook hack of the day

[William Stein]

Hi,

Have you ever given a presentation with the Sage notebook and been
annoyed by it "jumping all over the place" when you press shift-enter
or click "evaluate"? Then do:

html('<script>cell_focus=function(x,y){} </script>')

Great tip!

I also recommend you make sure everything works under zoom and at 1024x768.

That's different and important new development work. The hack below
was something I figured out because I was about to blow chunks while
trying to watch some presentations given using the Sage notebook this
week... and I have a high tolerance for disorienting motion.

Sorry. I wasn't clear. I meant when giving talks, you should make sure you have tried those things. The notebook tends to work fine, but you need to be careful about long lines and big images. :)

(assuming you meant "intolerance")....And you *skateboard*???

Dima had created a button for it, which said "Evaluate and stay" just next to the "Evaluate" button. It stopped the worksheet from jumping around. Maybe he can tell you in detail how he achieved that. :)

Cool ! At the Sage Days 38 we have been doing a lot of tutorial using notebook
with a lot of text at this is extremely annoying. Too bad we learn of it right
after the Days. By the way, half a dozen of those tutorials should be
contributed to Sage in a short amount of time (they needs some cleanup and
polishing). Among them:
- Basic Python programming;
- Basic Cython programming;
- Combinatorics;
- Contributing to Sage;
- Testing conjecture in Parallel;
...
Cheers,

Florent

Thanks! The cython tutorial is very interesting. I always wondered how to handle for loops and lists.

I noticed some minor typos, but in

http://combinat.sagemath.org/doc/thematic_tutorials/tutorial-editing-sage-sources.html#a-real-modification

there's a serious one (Section 4): It still has the wrong editing
command there:

gedit /opt/sage/local/lib/python2.6/site-packages/sage/combinat/
permutation.py

which will really confuse people. Perhaps suggest using the "edit"
command instead? That will do the required path substitution.
