Dear Sage-Devel, Markus Hohenwarter (lead developer of Geogebra) and I spent a lot of time talking at a conference this summer in Barcelona. As a result, he's created geogebra applets that both technically and legally (!) can (hopefully) easily be integrated into the Sage notebook. See below for more details. Is anybody interesting in trying this out? Geogebra has hundreds of thousands of users and satisfy a real need for a certain target audience that overlaps with our audience.
- William ---------- Forwarded message ---------- From: Markus Hohenwarter Date: Wed, Nov 11, 2009 at 5:04 PM Subject: Fwd: Unsigned GeoGebra Applets To: William Stein <wst...@gmail.com> Dear William, we now have unsigned GeoGebra applets as the default in our latest release (see message below). If you would like to use them in Sage, you can use the jar files from http://www.geogebra.org/webstart/unsigned/unpacked/. All jar files are under GPL except geogebra_properties.jar which is under an incompatible Creative Commons license. To use GeoGebra applets you only need these files: geogebra.jar geogebra_main.jar geogebra_gui.jar (needed for LaTeX rendering, and other views like the spreadsheet) geogebra_cas.jar (only needed when derivatives or integrals are used in a GeoGebra construction) All jar files are loaded on demand only. We also have highly compressed pack200 versions at http://www.geogebra.org/webstart/unsigned/packed/ with much smaller sizes that our server automatically deploys to all Java 1.5+ clients.

Here are the cool news: * No more security question popping up for you or your students. This means easier and faster use of GeoGebra applets. * One-file-solution: now you can export your dynamic worksheet as a single html file. This makes it very easy to include it on your own website or send it to students. Just try "File, Export Dynamic Worksheet" in the new WebStart version. We have already updated all dynamic worksheets on the GeoGebra server to use unsigned applets and thus come without the security question. If you would like to learn more, please read the technical details of unsigned GeoGebra applets: http://www.geogebra.org/en/wiki/index.php/Unsigned_GeoGebra_Applets All best wishes, Markus & Mike -- William Stein Associate Professor of Mathematics University of Washington http://wstein.org --~--~---------~--~----~------------~-------~--~----~ To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
