I'm reading this in comp.lang.lisp, and have no opinion on js libraries, or indeed js at all. I tried your site the other day, and found it painfully slow to load. This was at work, where we have a 100Mbit pipe to the relevant transit provider, but I'm located in Europe, so the latency might be a bit worse than in NYC. I didn't time it, but I managed to switch to another virtual desktop, read a mail, and switch back before the page rendered. It popped up a firebug console with lots of scary-looking messages that I ignored. Typing was bearable, but only just, there was a quite noticable lag before anything rendered. I sometimes had trouble editing text I wrote, and I couln't type < or > at all. I clicked the "solved" button prematurely, and got an error message telling me to do more work, but I was unable to return to editing the text. This was on my normal work PC, an old Ubuntu install, 64 bit Firefox 3.0.something. I tried at home now to see if the slowness was reproducible. "At home" means MacOSX, Firefox 3.6.4, 25Mbit net connection. The slowness was not reproducible here, because the page failed to render at all. The firebug panel appeared, this time without scary messages, but the rest of the page was a uniform, boring gray. I know cells is cool and all, but I wasn't exactly blown away by this demo, sorry. ....Peder... -- I wish a new life awaited _me_ in some off-world colony.

To be fair though, the uniform boring gray page *did* load and render very quickly. ;-) sherm-- -- Sherm Pendley <www.shermpendley.com> <www.camelbones.org> Cocoa Developer

The rice is on time and the challenge (not too hard) is knowing what to work on first. Performance is outstanding and you want me to work on that now?

Plonk. > My name is Gildas, not comp.lang.javascript and it's the first time I > post here. So, I don't think I'm known as a "library hater". OK. But you are actually annoyed by meaningless XHRs? I am reminded of someone who complained that my desktop app was 40mb. When asked, he said it had taken twenty seconds to download. And the problem is? So you are right, people get bothered quite a bit by what I call "machine empathy". They imagine themselves running back and forth 3000 miles carrying envelopes with XHRs inside and become outraged. Um, no, as far as I can tell it is not worth addressing just yet, though certainly at some point it should be addressed if only because it is indeed unnecessary. Thanks for the well-meant report. > BTW, the alt key does not seem to work (maybe a french laptop keyboard > issue) so I'm unable to type the last formula in the tutorial. Thanks again for the report, but to anyone out there, please relax on the bug reports. I have prominently announced that the thing is known to be broken and incomplete and is being shared only for what does work (which will expand in Algebra tutorial functionality before anything else, except for tree bugs that make the tutorial forest impossible to see). kt -- http://www.stuckonalgebra.com "The best Algebra tutorial program I have seen... in a class by itself."
