How I spent New Year's Eve day
New Year's Eve was spent quietly, with the family: the kids actually managed to stay awake until midnight -- even B2, who usually wanders off and falls asleep before everyone else.
But the day of New Year's Eve, I spent puttering about with a "marble maze" kit -- or rather, three of them combined -- experimenting with binomial distributions.
Because, you know -- that's what you do on vacation.
Note that I make some comments in there that alludes to OCD-ness. If I was **truly** OCD, then I would've done more than five iterations. ;)
