UTF8 encoded Japanese in LaTeX

Slightly off topic, but anyway... notes on getting Japanese text working in LaTeX under Mac OS X using TeX Live. Once I finally got it to work it is quite easy, but first I explored a lot of dead ends and distractions (in the end I could ignore LaTeX Omega, XeLaTeX, etc).

Interview with a PeerJ author (me)

This summer I submitted a paper to the innovative new open access journal PeerJ, where it was published this week (Cock et al. 2013). I decided to write up the experience in the style of the PeerJ's Interview with an Author blog posts. I've copied the questions they normally ask, and written up my own replies - other than some rough edges in their current submission system it was all good.

Update: This has been reposted on the official PeerJ blog, with responses which I have inserted below.
