A fully developed hurricane can release heat energy at a rate of 5 to 20x1013 watts and converts less than 10% of the heat into the mechanical energy of the wind. The heat release is equivalent to a 10-megaton nuclear bomb exploding every 20 minutes. According to the 1993 World Almanac, the entire human race used energy at a rate of 1013 watts in 1990, a rate less than 20% of the power of a hurricane.

I recently tried Internet telephony for the first time with Speak Freely. Worked like a charme (from Windows to Windows, in our case). Unfortunately, Speak Freely will be discontinued. As Walker writes, the Intenet is a different place now than it was when he wrote Speak Freely. One problem being that many machines on the Internet sit behind NATs. Who would really know how to work around that? Well, somebody like the KaZaA guys. So they did, with Skype.

10. POSTDOC

Sure, some Ph.D.s do enriching work in their postdoc "year" (this limbo between earning the doctorate and getting a real job has in fact grown to a more typical two, three or four years)—but in an obscene number of cases, it's just drudgery leading to dashed dreams, for the simple reason that we produce many more science and engineering Ph.D.s in this country than we have professorships to fill. The academy line is that, overall, the postdoc is a beneficial "winnowing-out time": The fittest scientists are selected, while the rest flee to lesser callings (like … picking randomly here … science journalism). But, to extend the Darwinian metaphor, overwhelming anecdotal evidence suggests that the postdoc limbo selects not for intellectual fitness to be a scientist but for sheer endurance to put up with 80-hour weeks of, say, sticking electrodes in rat brains and getting bitten. People with interests in family, art or recreation are the most likely to bail. As well-rounded minds, they're also potentially the best scientists.

As you can see in my case, choosing a catchy title and tag line for a blog isn't easy. So I have to express my admiration for this: A Man with a Ph.D. - Richard Gayle's Weblog: "An attempt to use Radio to further my goal for world domination through the study of biology, computing and knowledge management."

High tech's missionaries of sloppiness: "Japan would always lag behind America in software innovation and sales because of a business culture in which perfectionism is rampant." Because innovation is more important than quality. Sigh.

I got a license from Habeas. Not because an email of mine got actually blocked, but it seems to be a pretty cute concept: The license allows me to include a haiku from Habeas in my email headers. Emails with those headers should be able to pass spam filters more easily. And Habeas is suing spammers who just copy that Haiku. And winning. (And kicking out their founder. Whatever.)
