On the php|architect site today there's a wrap-up from Keith Casey about the latest DC PHP User Group meeting where Scott MacVicar from Facebook presented on HipHop.

[Scott's] title is "Open Source Developer Advocate" which puts him in the odd position of making good things happen within Facebook, representing them to the community, and convincing the community to get involved. Towards that goal, this presentation was the last stop of a short tour to present HipHop to PHP groups.

He mentions the stats Scott shared - the size of Facebook's image hosting, the time spent on the site by the average user - and, of course, details on how HipHop helps them with his crushing load of users. He was also asked a question on the lips of many a developer out there - why would Facebook release HipHop for public consumption? You'll have to read the post to find out.

The DC PHP Conference has announced their Call for Papers for this year's conference (being held June 1st and 2nd):

In its fourth year, the DC PHP Conference will bring together PHP practitioners, business managers, and government officials from around the world for two days of exceptional presentations and outstanding networking events. The DC PHP Conference returns to George Washington University, Washington, DC, June 1 & 2, 2009, and promises to be the biggest DC PHP Conference yet!

The Call for Papers will close April 1st, so be sure to get your submission in quickly! They give a list of some of the "areas of interest" you might look into when proposing the talk including best practices, the "art of PHP", PHP in the Enterprise and general Open Source topics.
