It's already in the code for Dokeos 1.8.5 since 2 weeks ago: files extensions filtering. It was possible, in 1.8.4, to filter files extensions coming from ZIP files, but I didn't have time back then to include a widespread file filtering. It is included now. There is still a problem whereby Windows interprets files looking inside them, so it does not need the extension to be wrong in order to execute the file as is needed for a virus to spread.

I don't know why exactly, maybe it's because some system administrators go on holiday, or maybe it's because evil students (understand young crackers) are on holiday themselves, but the festive season is always a time when we have more attempted security attacks on our servers. Oh, by the way, hackers are just people looking into the code to change it, they're not evil. Crackers are people getting onto other's systems and trying to misuse it.

I'm currenty doing two things in Dokeos

1. adding and extending the gradebook extension (originally developed by Bert Steppé and Stijn Konings while on internship at Hogeschool Gent)
2. adding a certificates system, based on the gradebook (or more precisely on an evaluation from the gradebook), so that a student can print a certificate once he has succesfully completed an evaluation/course/learning-process

The first part is almost complete (added the learning paths as a evaluable resource and allowed evaluations to spread over several courses).

Opera has recently decided to sue Microsoft in the European Court for

• making it difficult for users to choose another browser (as I understand it, to remove Internet Explorer easily and replace it by another one)
• not respecting web standards

This second point is of incredible importance for the future of the web. I'm glad somebody's done it. More info here: http://people.opera.com/howcome/2007/msft/

[digg=http://digg.com/software/LDAP_Active_Directory_and_LDAP_SSO] I've had to reply to part of a call for tender today. The interesting question was "Can Dokeos interact with our LDAP/SSO system?". So first I should review the vocabulary a bit.

This is a list of sites where some public calls for tenders are listed: Bulletin des adjudications: http://www.ejustice.just.fgov.be/bul/bulf.htm En Tenders Electronic Daily: http://ted.europa.eu/

I've mentioned SCORM before, but I didn't enter into the details.

Xapian is one of the indexation/search engines I'm planning on integrating to Dokeos instead of the current indexation/search engine that we have at the moment: MnoGoSearch. There are many reasons for that change:

• MnoGoSearch server is not GPL under Window, which makes it impossible for us to ship as part of Dokeos
• MnoGoSearch has crappy support mailin-lists
• MnoGoSearch's packages in various distributions are not maintained
• Xapian has *many* interfaces in many languages, all regularly maintained.

Every month, there are 3 to 5 big projects I am working on.
