If you've never presented at a conference before, sometimes a smaller
regional conference is an easier way to get started. Madison PHP is one day
(Saturday, September 13th, 2014) and seeks talks for attendees at all skill
levels. And their speaker compensation package includes complimentary
airfare/travel and hotel.
I suggest you submit talks:
* on MediaWiki extension development, like
http://opensourcebridge.org/wiki/2014/Extension_Development_with_Mediawiki
(slides available)
* on HipHop and HHVM
* on coding conventions
https://www.mediawiki.org/wiki/Manual:Coding_conventions/PHP
* on how you do code review
The proposal deadline is Monday, July 21.
