Bruce Schneier has released a special edition of his monthly Crypto-Gram security newsletter. This issue discusses security & technology topics relating to the September 11th attack. It is not strictly Unix related, but I think it is well worth the read as it contains a lot of well-though out, interesting information.
Recommended reading for anyone interested in techology. (it is long: approx 18 pages)

Those of you in the US, if nothing else read the last section entitled "How to Help". A quote from the article:
"We have less than 100 hours before Congress acts on legislation that will (a) significantly expand the use of Carnivore, (b) make computer hacking a form of terrorism, (c) expand electronic surveillance in routine criminal investigations, and (d) reduce government accountability."
