,
a science museum
exhibit. Now under development for delivery to science centers in
2004. The previous software has run for over 10 years in several
locations.
I am working on an upgrade.
. Playing with modern implementations
of old challenge/response authentication tokens that didn't have
RSA's weaknesses. Also trying to get enough entropy out of
passgraphs/passmaps to hide keys from dictionary attacks, while maintaining
usability. Logging in should be fun!
Algorithmic passwords
(2002). Given
this list of challenges, responses, and
whether the authentication succeeded, can you figure out this
rather simple algorithmic password? I have been thinking that
these would be useful for emergency backdoors, robust and inscrutible
for, say, a dozen uses.
I have been running a tiny packet telescope since June 2005.
Here's a graph of the packet types seen.
Every packet captured is available in a tcpdump, upon request.
, a new prescription drug
for treating obesity, is not yet approved by tha FDA. But it
is approved in Europe, and I am on it, with the oversight of
my doctor. In the first three months I have lost 5% of my body weight
(6kg, 13pounds) during the summer, without dieting.
My diary contains updates.
At this point, the Authorities have decided that the suicide rate
is too high, and have discontinued manufacture. This stuff
cut my weight a little, and improved my blood sugar. Don't hold
your breath for personalized medicine.
.
This spam-advertised stuff actually works for weight loss, at least
a little. I lost about 1% of my weight, which might be more than the
placebo effect. But see rimonabant,
above, which is now discontinued.
. I have hooked a USB camera up to a laptop,
and made an assortment of time-lapse movies:
Snow On (11 MB),
Snow Off (8.5 MB), and
Sep 10 (2 MB), a
hand-held brief experimental time lapse taken out the window
of United Flight 93 on 10 September 2001.
Peter!
