I have got a heap of work off my desk thanks to delivering a heap of trackers to the local post office for delivery to a client of mine. The box should arrive there in a couple of days thanks to ‘express post’ being not quite so fast in parts of the country outside the capital cities. In fact very little of the land area of the country can get express post the next day. They normally get packages the 2nd or 3rd day. I am glad I am not in that part of the country!

United Nuclear is now selling AeroGel which is sometimes called ‘Frozen Smoke’. It is technically made of the same stuff as glass but weighs 1000 times less… They use it on space probes to capture particles for return to earth.

The SANS web site is dedicated to computer secrity. They have a story on how the president of the USA recently visited the National Security Agency in the USA, and they had the SANS dshield live page up in the background suggesting that the NSA were actively monitoring computer security, rather than just examining the results of other people monitoring computer security.
