I have been creating Podcasts using Keynote and iMovie. This has been working fine, and I have created podcasts that cover a basic calculus course completely.

Yesterday I needed to create another podcast. I started my Keynote, produced and recorded the presentation, and exported it to Quicktime. But no sound. The recording did not play anymore when the presentation was exported to Quicktime.

I found out that the culprit was the new version (4.5) of Quicktime. See

Did you notice the live feed monitor, on the left column, under the "Online Now" header? We just added it yesterday to show you how traffic comes to our JEM pages, what pages are hit mostly, by which search phrases (some puzzling ones too). You can also see the map of the traffic, generated live.

We now have the guide for building a learning repository on Drupal 5.x available in english, spanish and french; the guide instructs through the process of building a similar learning repository as on the JEM website.

The guide is available currently at:

• English version, http://www.jem-thematic.net/en/node/715
• French version, http://www.jem-thematic.net/fr/node/787
• Spanish version, http://www.jem-thematic.net/es/node/781

I was very frustrated by the podcast page of Mika since the movies never played on my preferred Firefox browser under Linux. I complained to him and he added the disclaimer These podcasts require QuickTime. They will not run on a generic player. to his Calculus podcasts page.

We have moved the JEM website to a new server due to problems with the old webhost provider and the website should be running smoothly now.

What precisely did we do:

• Move the databases
• Move the site contents
• Redirect the domain www.jem-thematic.net to the new server by changing the A record
• Some apache reconfiguration (virtual hosts etc)

Please comment on this blog entry or through the contact form if you notice any unexpected behavior on the website.

We hope this solves some of the peculiar behavior like page timeouts and 503 errors experienced on the old webhost.

During the last NORMA08, I was made aware of a Leonardo project called EVLM, European Virtual Laboratory of Mathematics. The basic idea of this project is to establish the virtual lab of mathematics and to promote better understanding and utilisation of mathematical knowledge in a range of other disciplines that are underpinned by mathematics.

This semester I have been teaching two large sections of calculus I at Florida State University. FSU is a big time BlackBoard user. The system has been in use for many years and always worked fine. Until this week. This is also the last week of classes. Final examinations are next week. Hence this week is extremely busy time students using BlackBoard to prepare for the final examinations or to submit course work. Hence closing down BlackBoard and restarting it is not really an option.

We have now enabled Atom feeds on the JEM website. The feed is available for the main page and the blogs at the urls http://www.jem-thematic.net/atom/feed and http://www.jem-thematic.net/blog/atom/feed.

For an appropriate atom reader, try out for example the following: http://www.feedreader.com/

We missed it, the world's first Document Freedom Day advocating free open standards for documents. This includes MathML and OpenMath and OMDOC and MathDox!
