sequestering carbon, several books at a time XXVII

Surprisingly, a batch of all non-fiction this time:

I've been after Aczel’s Non-Well-Founded Sets for a while, and finally a second hand copy popped up at a not-too-ridiculous price.

A colleague at work was enthusing to me about Scala in general, and Horstmann's Scala for the Impatient in particular, so I decided to find out what the fuss is about.

Begon et al’s Ecology is there as potential source material for realistic ALife simulations.
