I'm a fan of Asciidoc and the Ruby Asciidoctor implementation (it's what I use to markup my weblog posts). I enjoyed this interview with Dan Allen, the main developer behind Asciidoctor.

"Dan share's so much valuable insight into why Asciidoc is the premiere format for writing, regardless of the type of work you do, how the format came to life, some of the tooling available, plus so much more.

If you're just getting in to technical writing, love documenting your code, but want to spend less time doing it, or just want to find a tool chain that demands less of you, but gives you so much more, then grab your favourite beverage, put your feet up, and tune in!"

A very handy overview and comparison of the various file-locking mechanisms available on Unix systems (includes Linux 3.15's "open file description locks").
