On the Symfony blog there's a new post about the Symfony Live Portland schedule being published:

We have finally selected all the great speakers that will share their experience with the Framework with you at Symfony Live Portland 2013. We had a very hard time choosing among all the excellent talks’ proposals we received. After a long time of thinking, we are very pleased to publish the talks we think you most want to attend for this edition. For the first time in the USA, there will be 2 tracks per day; more than 20 talks are scheduled, a lightning talk session and the now famous Jeopardy session with the fantastic Jeremy Mikola! Let’s say that it will be now your turn to have a hard time choosing among these great talks! Have a look now at the schedule and register to the conference!

They also mention the availability of the Symfony certification and that they're still looking for sponsors for this year's event. You can register now and pick up tickets for about $400 USD ($600 for the Combo pass).

The schedule for this year's OSCON conference has officially been announced and there's several PHP sessions on the schedule this year including:

• The MicroPHP Manifesto (Ed Finkler)
• Get Some Rest: Best RESTful API Practices (Lorna Mitchell)
