The deadline submission for DEBS 2010 is approaching, tomorrow the abstracts for the industry and research tracks should be submitted. My role in this year's DEBS organization is to serve as tutorial chair. Thus, I am using this opportunity to solicit proposals for tutorials. The tutorial program in DEBS started in 2008 and continued in 2009, in both cases there was a tutorial day preceding the main conference, whose content you can find using the links above. The idea of a tutorial is to provide in-depth survey of teaching a topic that is of interest to the conference's audience. Tutorials can be 1.5 hours or 3 hours long. More details can be found in the call for tutorials. Tutorial submission type is next week, anybody who can contribute a good tutorial is encouraged to send. Last year I have participated in giving a tutorial about event processing languages, we have put the slides on slideshare, checking today it had so far 2861 downloads, so it also may have high visibility.
