WordPress Code Flow

I was interested in checking out how the WordPress code flow works… When I googled it, ( probably with the wrong keywrods), all I ended up was this;

which is an excellent shot at it but very very old thus worth nothing today.

I also searched how the heck wp_head works, could not find it neither.

In order to understand wp from the ground up, I thoght I should get a full grasp of from url to all the way to wp_footer() what really happens… Ant pointers in this regard is highly appreciated.

Thanks

Probably the Program Flow on ToolPress is something for you: WordPress 3.0 Program Flow File Inclusions (Default Request); PDF. Contains important filenames, constants and hooks. My Favorite Cheat Sheet so far for the code flow stuff.
