The deadline for submitting paper proposals for Linux.conf.au 2013 in Canberra was originally supposed to be last Friday, but has now been extended by a fortnight. Am I bitter that I set aside time to make sure I submitted my proposal before the deadline? No. (Grinds teeth.)
Actually, I'm glad I didn't know about the extension until after the deadline changed -- I'd already waited until the last day as it was to finish working on my draft. The new closing date is now June 20.
While we're talking open source conferences, a reminder that WordCamp Sydney 2012 is coming up in a fortnight and you can score a discount on the registration fee.
