I notice from the Emacs Rocks twitter feed that Magnar Sveen has started a new blog called What the .emacs.d!? It’s about setting up Emacs and each post features a bit of code from Sveen’s .emacs.d directory. You can, of course, see his entire .emacs.d setup at any time by visiting GitHub but these posts explain what each bit is doing and why he is doing it.
It’s brand new and has only 3 posts so far but as you would expect from Sveen, it’s excellent. I’m looking forward to seeing more posts.
