day 4 of the beard and the Crypto museum

The day 2 picture had an NSA coffee mug in the background. I purchased it from the gift shop of the National Cryptologic museum at Ft Meade, Maryland. I highly recommend that museum, it has free entrance, hardly any visitors (I've never seen more than 5 people in there) lots of interesting displays, and some really intelligent and well-informed tour-guides. If you are interested in technology then you should visit the Cryptologic museum and the Smithsonian every time you visit Washington DC.

Last time I visited the Crypto museum they had a new display about fingerprint scanning. It displayed what the machine read and indicated whether the fingerprint was regarded as a match or not. I learned that I could get a false negative by changing the angle of my finger by about 20 degrees, but apart from that it seemed more accurate than I had expected.

Here is a picture of me touching an Enigma at the Crypto museum! There is also a picture of me sitting on a Cray with some Japanese friends, but I haven't got a copy of that one.

In regard to Shintaro's comment about thinking I had a beard after reading backup.te, I was a little surprised, I would have thought that mta.te (which is fairly complex) or chroot.te (one of the most complex and least used policy modules I ever wrote) would have inspired such a comment. backup.te seemed rather mundane by comparison.
