Org-mode and LaTeX
Speaking of Org-mode, which I seem to be doing frequently lately, the indispensable Emacs-Fu has a very nice post on producing PDF documents with Org-mode and LaTeX. Org-mode has always exported its documents to LaTeX (at least as long as I've used it) so this isn't anything new but djcb tells us how to change the fonts a bit so that your documents don't look like every other LaTeX document in the known universe.
That sameness in document look and feel is one of the reasons that I prefer to do my writing with Groff, but take a look at the sample document that djcb produces and see if you don't agree that it looks very nice. As usual, it's hard to read Emacs-Fu without learning something useful.
