Thanks :). To plug myself, I quite like http://robertheaton.com/2014/01/06/how-to-win-at-dinner-part...

I really liked your article on how to take over Rails servers if they leak their secret.

Shouldn't the brown-eyed people kill themselves on day 101? Or are they supposed to reason that they, and they alone might have some other coloured eyes.

This is true - it depends on whether they know there are exactly 2 different eye colours on the island. I should clarify that!

Also, since you're not allowed to talk about it, if you work out you have blue eyes you could just keep your mouth shut.

They do seem to be going to an awful lot of effort to top themselves.
