Hi Bill, Well, I really was just joking around about the "distinguished" bit. ;-) You've got some great points. Maintaining version x.y.z of the necessary software is a very interesting idea, though I'd guess maybe at some point the lifetime of hardware might end up being a limiting factor? I

I think JSage has a slightly different focus. Specifically: * It is tied to the Sage Python library * It is intended for people who have a complementary publication in a traditional journal * The code has to be included in Sage and be maintained there * The board of editors consists of Sage devel

Ah, silly me. The "evaluate" goes away when another cell is selected. No need to worry about solving that "problem". By the way, how do I use the %latex mode in a cell? It looks like it expects whatever you would have in a latex slide. But $2+2$ for example does not latex. Bill. On 12 Apr, 00

It doesn't seem to be imported by default. There's no other diagram package imported by default is there? I guess it would be even better to be able to do CD's outside cells, but would I be correct in thinking that is a limitation of jsMath, not the notebook? I'm really impressed by the notebook
