The Ottawa Perl Mongers will be meeting once again at the Pythian headquarters. There will be two presentations given: Yanick Chanpoux will be presenting on Moose. Tim Procter (myself) will be presenting on Portable Perl Daemons. The focus is on developing light-weight background processes that will be compatible with both Unix and Windows systems. Additionally, I will be demonstrating communications with the daemon and child processes over TCP from an independent controller. The presentations are now available online thanks to Andrew Ross at the Free and Open Source Software Learning Centre. Comments are welcome.
