They say that travel broadens the mind. My childhood journeys provided ample contradictory evidence, though ("Ow! Stop it! Shut up! It wasn't me! He did it! Ow! Ow! If you don't behave I'll stop the car...").

Anyway. I think it's really a second-order effect: travellers read a lot, and reading broadens the mind. I don't get out so much, and my desktop is littered with PDFs which I shoulda coulda read; on a quiet morning I sometimes find time to scan through them.

Today's selection:

• Ray's recommendation of Power to the Edge certainly needs more time. The first couple of chapters are way more interesting and provocative than I'd imagined from the provenance.
• S.Norrie pointed to Software Architecture as a Shared Mental Model. Very nice clear (short) exposition of something which should have been blindingly obvious but wasn't.
• Foundations of Functional Programming, all about the lambda calculus and stuff (and I even understand a little of it).
