Euruko 2003 Videos available at   25 Sep 04
[print link all ]


The First European Ruby Conference was held at the University of Karlsruhein in Germany, from the 21st to the 22th of June, 2003. It was organized by Michael Neumann, Stefan Schmiedl, Armin Roehrl and with the help from many others.

Thanks to Michael, the presentations were digitally recorded and have been made available as AVI files. Some of theses are now available for download from The videos have had the some noise filtering and volume normalization applied, and have been converted to MPEG-1 to reduce (albeit slightly) their size.

Not all of the videos are available right now. Others will go up as time permits me to do the file processing.

I initially had some FTP timeout trouble uploading the files to, so I split them into chunks. I decided to leave them this way to help avoid marathon download sessions. To combine the chunks into the complete file you basically just need to 'cat' them in sequence. I've written a Ruby script to do this, available from the video download page. If anyone thinks they can mirror any of these files it would be a tremendous help.

If you know anything about video compression, and can tell me a way to make the files smaller without serious loss of quality, please tell me.

Just look at the "eval.c" file, i think the require is defined there and then write your hook. Or write a dll/so and add embedd your rb files as large c strings there (using maybe the "wrap" tool from the Fox Toolkit) and then do rb_eval_string("my c file"). After this protect the dll with something like "armadillo" (use google to find the URL). This works perfectly for me.
