Second day, and already behind
Herm. I’m having a go at helping Jeremy review his book. Partially because of timezone differences and partially because of giving a talk on my Blosxom blogging engine at a users group last night I’m already a little behind. Time to knuckle down and do some serious reading me thinks. [tags:]
Tipping Point: Gaetan Dugas, the AIDS patient zero
Page 21 of The Tipping Point mentions Gaetan Dugas, the so-called AIDS patient zero: “…the French-Canadian flight attendant, who claimed to have 2,500 sexual partners in North America, and who was linked to at least 40 of the earliest cases of AIDS in California and New York…” Assuming this time line of the AIDS epidemic…
Essex secret bunker
Note to self: if I ever find myself in Essex, I should go along and see the Essex secret bunker, which was a nuclear disaster emergency control center.

This can have some…

Here are the ones relevant to this topic area: September 2001: Australian Unix User’s Group Annual Conference Proceedings, Open Source PDF handling with Panda and PandaLex (not online at the moment,…
Sick Twinkle Tux
Herm. Twinkle Tux just had one of it’s transformers fail. I’m not sure if it was because of temperature (it was a warm day and I had left Twinkle Tux on all day as I got slack), or if it was just due to fail. Luckily I had a hot spare, so Twinkle Tux is…
