I think at that level you don't really learn stuff through tutorials anymore. Tutorials/conferences stuff are mostly to get you started and looking in the right direction. You learn the advanced stuff by doing it. Want to learn linux kernel internals? Write a kernel module. It doesn't have to be useful. Want to learn webkit internals? Invent a new tag (super-blink!) and implement it. It's extremely unlikely that W3 will appreciate your contribution to html but you'll learn a lot in the process. Another way to learn this stuff (and a pretty standard way to introduce new people to a codebase in the industry) is to jump into the bug tracker. Just start fixing low-priority bugs. It might take you three days to find something that a core dev could fix in fifteen minutes, but you'll learn an immense amount in the process.
