Fwd: Unsigned GeoGebra Applets

[William Stein]

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.

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.

All best wishes,
Markus

Dear friends,

we have just released GeoGebra Webstart 3.2.31.0
(http://www.geogebra.org/webstart/) and with it unsigned GeoGebra
applets. 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

I am interested, although I don't have a lot of time...just last week, I
downloaded GeoGebra for the very first time, and in maybe 45 minutes of
goofing around and reading documentation on the internet, made this:

http://mathsci.kaist.ac.kr/~drake/complex_cosine.html

(Try double-clicking on the applet to open up a full-fledged GeoGebra
editor!)

GeoGebra has its limitations, but clearly for some things it is
extremely useful, easy to use, and makes it trivial to put up things for
students. So I'll try it out.

Cool. By the way, Markus adds:

"Dear William,

we'd be happy to help you get this into Sage. Just let me know if you
need our help.

All the best,
Markus"

So -- like with Jmol -- they will be very helpful.

William, this could be really great, for many reasons - perhaps even
funding. I am cc:ing this to sage-edu, as some people there probably
will be interested. I am certainly interested in trying it out, if I
can figure out how :)

How did you envision the applets integrated into the notebook - on an
on-demand basis for @interact-like things for specific purposes (say,
drawing hyperbolic triangles), as a menu option "insert a Geogebra
applet from list X here", or something more integrated than that into
the Sagenb spkg?

For starters, I imagine a command, e.g.,

geogebra(various options???)

that results in a geogebra applet appearing? Then that could be used as a
building block for much, much more. What do you imagine?

And yes, I imagine the actual java applet's could go into sagenb at
some point...

Cool, thanks Dan. That inspired me to actually take a good look at
geogebra. I think it would be fantastic to have this in the
notebook. I'm not sure I'll have enough time to seriously help in the
near future but I'll do what I can.

Those ideas make a lot of sense. What would be good is to have some
"translation service" that would automatically turn interacts which
*could* be done in Geogebra (which would certainly not be all of them)
to be done that way, so that the real-time is much closer to
Manipulate and jmol. I only know how to create Geogebra things using
the GUI, but if there is an underlying text representation that would
be great.

Of course, I doubt that is even feasible, but even a @geogebra
decorator for the notebook which one could use in the same way as
@interact, and would have its own documentation, would be great. We
already have Java. Interestingly, since Geogebra uses Yacas, we would
potentially have access to Maxima, Yacas, etc. - but not sure if it
would be difficult to access things like that via Python->Java-
>Python.
