From: Kenneth Tilton on 29 Jun 2010 06:43 Now you can ask for hints (and a bunch more is fixed): http://teamalgebra.com/ I like -3x > 15 because then it offers two hints, one about dividing on both sides and one about flipping the inequality. That is the qooxdoo JS library driven by a Lisp server app running AllegroServe, all with Cells Inside(tm), running on an AWS 64-bit instance. Don't mind the whacky color scheme, that is just leftover debuggery to help me sort out the qooxdoo layout manager. It's pretty powerful hence sometimes surprising. Bit of a bummer: that is still running on a 64-bit AWS instance because the app hangs somewhere installed on a 32-bitter. Hmmm, I have VM Workstation....awesome, I will be able to debug using the ACL IDE. kt -- http://www.stuckonalgebra.com "The best Algebra tutorial program I have seen... in a class by itself."

That error being:- Line: 5180 Char: 9 Error: Image modification not possible because elements could not be replaced at runtime anymore! Code: 0 URL: http://temoalgebra.com/ (It is a custom error, presumably produced by whatever library you are using, but what on earth is that "anymore" about? A browser either can replace elements at runtime or it cannot; it is not a faculty that comes and goes). And don't you think that a 2.5 MB download is a little excessive for a single web page (even if it were actually functional)? Richard.

It is based on qooxlisp, a great JS library, is the point. that produces a javascript error before it even finishes Works for me on Chrome, FireFox, Safari, and IE.

Last I looked it was ~800k and the "single web page" is the entire web application (which was 40mb as a desltop app). Kids will work on Algebra for 10-50 minutes at a time, they'll wait 2-3s. kt -- http://www.stuckonalgebra.com "The best Algebra tutorial program I have seen... in a class by itself." Macworld

The point you are making about qooxlisp is probably not the point you think you are making. > that produces a javascript error before it even finishes > > Works for me on Chrome, FireFox, Safari, and IE.

Try:http://teamalgebra.com/ It is a typo. > Nice bug report. No browser, no OS... What has the OS got to do with anything? And there is only one browser that outputs its error reports in that style (which means that only someone who was not looking at their error reports would not recognise it (which would also be someone who thought something was fine while it was generating errors)). >> (It is a custom error, presumably produced by whatever library >> you are using, but what on earth is that "anymore" about?
