On Tuesday Sept.10 I went to PHP TechTalks with Rasmus Lerdorf, Sebastian Bergmann, and Stig Bakken. Great initiative by Stig Bakken @ Zedge. The TechTalks focused on new features and best practices and for PHP 5.4 and 5.5.
Great feeling of going to the roots of LAMP and MySQL. Thanks for the invite Stig!
