Hollick Wines

Thursday, October 23rd, 2003

We enjoyed visiting Coonawarra Valley in Australia, and tasted several fine wines. We sent home a case of Hollick. We particularly enjoyed the Wilgha Shiraz, but we also bought a couple bottles of the sparkling Merlot – more for the novelty, but it was a nice wine.

Some interesting tidbits on brainstorming research. Most interesting: “Group brainstorming, used day in and day out by countless business owners, really doesn’t work that well, according to Paulus. You’re almost always better off directing your employees to brainstorm individually.” | A Perfect Brainstorm

World-wide sensor web

Monday, October 6th, 2003

This is a pretty dense but interesting article filled with the possibilities of a world-wide sensor web. Last week I got a tour of the Intel research lab in Berkeley and saw some more cool stuff like this. Amazing to wonder what life wil be like in 20-50 years…

Number theory

Thursday, October 2nd, 2003

Someone in my office asked how this worked. Below is my answer.

Fido Puzzle

This works because any number minus an anagram of it is guaranteed to be a multiple of 9 (4321-3214=1107=123*9). So, if you tell me all but one digit of the result (e.g. 107), I can deduce the missing one by adding up the digits mod 9 and subtracting from 9 (9-8=1). I’ve always loved number theory.
