Irina Deleanu Cup 2008

Last Sunday, Apr 6, 2008, was a rainy day, making me thinking what to do to escape my flat and relax before starting a new week.

By chance I learned about Irina Deleanu Cup 2008, a contest for Rhythmic Gymnastics — that was a great event and entertaining time. It is long time since I enjoyed so much my spare time. It is pity that this sport is not promoted better by the authorities.

There is a large sets of videos available on youtube:

More details here....

Moreover, another blogger made an analysis of German VoIP market and shows that billions of minutes per month are routed with Open Source applications, and of course, OpenSER has its big share, sustaining one of the biggest VoIP service in the world.

1.76 million of users on an OpenSER-based platform is not bad at all...

Module Documentation Now In Docbook XML Format

Migration from SGML to XML Docbook format is now ended for all OpenSER modules.

The format is much more flexible and allows easier conversion to different format. Using XSL, the look can become more user friendly, we can generate summaries, indexes and references to parameters, functions, MI commands and pseudo-variables exported by modules. Another target is creation of an aggregated tutorial, combining these documents along with a getting started guide.

Modules' documentation repository in HTML format can be found at:

http://www.openser.org/docs/modules/devel/

New documentation effort

Recently, the openser-docs mailing list was created to conduct the development on OpenSER documentation. If you want to join go to:

http://lists.openser.org/cgi-bin/mailman/listinfo/openser-docs

Immediate task is to create a master document where to refer the rest of documents, the entry point for new comers. The dokuwiki is already an impressive knowledge base, but lacks somehow a good index.

Another subject is to migrate the format to Docbook XML.The amount of available tools and the strict formating in XML provide easier ways to manage and convert to readable formants.

Off topic, worth to mention that RTPProxy got its own mailing list:
