Hi all, This is a bit odd, but is it possible to use an NSCalendar (or any component, for that matter) to figure out what the date of the next "first tuesday of the month" would be? For example, today is Thursday March 25, 2010. The next "first tuesday of the month" would be on April 6. Likewise, if I were looking for the next "first...

Short of ha...

OK so I have 4 buffers, 3 FBOs and a render buffer. Let me explain. I have a view FBO, which will store the scene before I render it to the render buffer.

Hello world, I've grown tired of the built-in open Mac OS X command, mostly because it runs programs with your actual user ID instead of the effective user ID; this results in the fact sudo open Foo opens Foo with its associated application with your account instead of the root account, and it annoys me. So I decided to make some kind o...
