Development

[digg=http://www.digg.com/programming/Tips_and_tricks_for_using_pseudo_CSS_in_OpenLaszlo_4] Having had to deal with this stuff lately with the Dokeos videoconference development, I thought it might be useful. The mainstream page is located on the Dokeos wiki, so in the following weeks, I recommend, looking at it over there. Here goes... The new version of the videoconference tool (to be out at the same time as Dokeos 1.8.5) can be theme-modified via CSS.

While on part-time holidays from Dokeos, I'm looking into some of the stuff I will need to be aware of when working on Dokeos for the next year.

One of our client is currently waiting for a rebrand of the videoconference tool, with which we have finally managed to remove the echo bug (using OpenLaszlo 4 and a few libraries fixed it).

I had to upgrade the reservations tool for Dokeos lately. Nothing much but a few variables and constants renaming, but the use of the module itself is quite a mystery to me.

A new version of this article has been compiled here to cover
version 10 of the Flash plugin which reportedly
supports V4L2 in its second beta version!

Mike Melanson, the (only?) developer assigned by Adobe to the Linux port of the Flash client, has announced on his blog t

2014 update: This article is outdated. To date, the library that matches most of the comparison elements below is mPDF.

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'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.
