Hollick Wines

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.

Brainstorming

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."

Table 1: Current 802.11 Working Groups at the IEEE

802.11 Specification letter suffix What it does
e Adds quality of service features, multimedia support
f Defining how access points interact
g Ups data transfer rates on 2.4GHz band to 54 Mbit/s
h Adding dynamic frequency selection to 802.11a to comply with European regulations
i Security upgrade
j A version of 802.11a for Japan that will run on the authorized 4.9GHz-5GHz frequencies
k Defines radio and network information to allow the better management of wireless LANs, will also enable new applications like location-based services
l Not being used, because it looks confusing
m Maintenance, this working group will go back and correct any errors in previous ammendents to the specification
n Not official yet but likely to be the designation of a high-throughput variant of the standard.

World-wide sensor web

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

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.
