gnat writes "The Call For Papers for the 2007 O'Reilly Open Source Convention (aka year 11 of The Perl Conference) is now open.  Submit a proposal before the rush.  The conference is in Portland again, July 23-27.
 
No topic is off-limits, so long as it's useful and interesting (and open source).  Sample topics the committee are particularly interested in:
 
 -  Tools for the administration and deployment of large server farms 
 
- Parallelization, grid, and multicore technologies
 
- Virtualization
 
- Ajax, Javascript, standards-based design, and other client-side web issues
 
- Seaside, Rails, Django, and other interesting server-side web technology
 
- Ubuntu as an emergent usable Linux distro and contender for Red Hat and Sun's client and server markets
 
- Java as open source
 
- AI, machine learning, and other ways of making software smarter than the people using it
 
- User experience and usability engineering lessons for web and desktop software
 
- The spread of open source into law, culture, data, and services and the accompanying issues and lessons
 
Perl specific suggestions:
- CPAN modules you know and love, and think others should know and love
 
- How you solved particularly thorny problems with Perl
 
- Useful yet tricky bits of Perl
 
- Your favourite Perl alternative to Rails
 
- The lessons you learned during (some big project)
 
- Your brilliant approach to (some common problem) that everyone else should be doing
 
- The recommendations system you wrote in Perl
 
- How you overthrew a tyrannical dictator using embedded Linux, four hundred lines of Perl, a Glock 9, and a heavily modded Lego Mindstorms kit.
