WordPress 3.5 is just around the corner. It's going to be released on December 5th, and while anyone can check out the current beta (look out for beta 3 soon), we've got a special treat for you. Daryl Koopersmith, a WordPress Core Developer, is going to talk about WordPress 3.5's media manager and how he built it.
Koop has been contributing to WordPress since version 3.0 and has been the lead developer on several of its recent user-facing features: menus, distraction-free writing, the theme customizer, and the media overhaul. Basically, if something makes WordPress cooler, there's a good chance he built it.
When Koop has a question about jQuery, he reads the minified version of its source. True story.
