We have now taken some small measures to improve the navigation on the website. this was done by adding breadcrumbs for individual nodes on the site, eg. the dissemination items, deliverables and some others.

You can now use the breadcrumbs to navigate directly back to the pages where the dissemination items etc are listed instead of having to go through the menu, for example:

Here is a nice collection of use cases for wikis in education. Nothing particularly related to mathematical education, but most of the uses cases are so general that they can be well adapted to our needs.

To get a true picture of the performance differences, I took snapshots of CPU and memory usage of Mac Pro and of MacBook Air while the computers where producing the movie discussed in my previous blog entry.

The picture above shows the CPU usage of my Mac Pro, and the picture below that of my MacBook Air.

We have done some customization on the views for the JEM partner pages.

For your comfort, we have added a listing of each partners dissemination items, case studies and software to the pages at About JEM -> The JEM Network -> <Partner Name>.

Any suggestions for improving the partner pages further are welcomed :)

I am spending a lot of time with podcast production. During the process of learning this trade I have gone through lots of hardware and software. From Windows to Mac, from USB microphones to condenser microphones etc.

We have this morning upgraded the menu system of the JEM portal. Please report if you notice any strange behavior :)

Sometimes you need a quick solution for notetaking. And when mathematical notation is involved, sometimes even LaTeX can be too slow. Enter two resources: on one hand, TiddlyWiki, "a reusable non-linear personal web notebook" and, on the other, ASCIIMathML.

The 4th workshop was arranged in Trondheim 12-13 of September 2008. It was a great success with 30 talks and 4 keynotes. Also very good social arrangements. The 4th JEM meeting was a satellite event on 11. September.

The French ministry of education organized a meeting entitles “L’Apprentissage des Sciences dans L’Europe de la Connaissance” that is right now taking place in Grenoble. Minister Xavier Darcos, the French minister of education, is talking and mentioned that, in France, during the last several years, physics has lost in average 5.5% of the student body a year. Several other countries report similar trends.

We have today taken action to upgrade the Drupal core engine powering the JEM portal to the latest version due to security issues found on the previous Drupal 5.x series of releases.

Security announcement on the issue is available at http://drupal.org/node/318706, please report any possible problems with the website.

Dominique has just announced that the odt2tbook plugin for OpenOffice.org has won an award. He does not mention he has been interviewed in a podcast about the OpenOffice.org community. Congratulations are in order!

The JEM server was down most of today, Saturday, September 27. The JEM server is located in a machine room of the Physics Department, and, of course, none of the administrators of the machine room was reachable off hours. Together with Antti Alamäki I then went to Campus, got the security guard to let us in to the machine room, and rebooted ubu, the JEM server.

It is possible to use our laboratory of curves in:
www.mat.uned.es/GeoCM/2PP/lab_curvas/_apps/matematica3d_20.app/matematic...
(please be patient, some times our server is very slow)
With this laboratory it possible to visualize the Frenet frame, osculatrix circle, evolute, osculatrix plane, ... and to compute curvature, torsion, arc length, ... of differential curves.
There are several curves previously defined and the user can introduce its favourite ones using parametrization or curvature and torsion (i.e. it is possible to experiment with the fundamental theorem of curves).
