Perceptual neuroscience — it’s all in the eye of beholder
I quite liked Beau Lotto’s article Look Here in May’s Wired UK. It’s not yet online, but googling it turned up a few other interesting tidbits on perception.
Beau Lotto has just published a book, Deviate: The Science of Seeing Differently, though reviewer Jonathan Rée hates it.
Michael Shemer’s TED talk, The pattern behind self-deception, explains how “the human tendency to believe strange things—from alien abductions to dowsing rod—boils down to two of the brain’s most basic, hard-wired survival skills. He explains what they are, and how they get us into trouble.”

Homebrew, rbenv, ruby-build, openssl…
How to upgrade OpenSSL on Mac OS. Homebrew issues led me down a lovely garden path… and this guide helped.
Explicitly specifying the OpenSSL can work when installing a new version of Ruby with rbenv.

Cockroaches live in a democracy
Cockroaches govern themselves in a very simple democracy where each insect has equal standing and group consultations precede decisions that affect the entire group, indicates a new study.
Halloy tested cockroach group behaviour by placing the insects in a dish that contained three shelters. The test was to see how the cockroaches would divide themselves into the shelters.
After much “consultation”, through antenna probing, touching and more, the cockroaches divided themselves up perfectly.
For example, if 50 insects were placed in a dish with three shelters, each with a capacity for 40 bugs, 25 roaches huddled together in the first shelter, 25 gathered in the second shelter, and the third was left vacant.
