  1. Re:Dresscode on Old Computers Exhibit · · Score: 1

    More likely, whenever Casual Friday got started. BTW, the last place I worked that imposed suit-and-tie on engineers gave up around 1997.

  2. Re:my house! on Using R44 And A PowerBook To Bust Illegal Seawalls · · Score: 1

    I used to bicycle past there, going from Oxnard to Santa Barbara. Behind the houses is a steep, unstable (look at the landslides) ridge, with more of the same inland. There's no place else for the freeway, or the railroad.

    Before the freeway there used to be a wooden causeway through this area , and before that a long, slow, mountain route some miles back of the beach.

  3. Re:my house! on Using R44 And A PowerBook To Bust Illegal Seawalls · · Score: 1

    I wouldn't want to live there; look at that BIG landslide behind you. :(

  4. Re: Muni in SF on Boston's Big Dig Delayed Because of Programmers? · · Score: 1

    In 1997, and maybe before, Muni was no longer publishing timetables, being only willing to list service intervals on the back of its map.

  5. Re:Rational Bias on Embryonic Stem Cell Research Legalized in California · · Score: 1

    Wasn't this proven logically by some famous mathematician over hundreds of pages of material?


    Two of them, Russell and Whitehead. Have a look here

  6. Scientific Applications for Gliders on World's Largest Airborne Telescope Delivered · · Score: 1

    NASA's ER-1 (U-2 variant) is used for in-situ high altitude atmospheric analysis. A 100,000-foot glider could do similar work, trading off mission duration for higher altitude.

  7. Re:Observing on Perseid Meteor Showers · · Score: 1

    If you have a hot tub in the right place, that's a great place to be when observing!

    Like here?

    I saw the big Peresid shower of 1994 from the hot tubs. Cool and a half.

  8. Re:Why isn't it on cars? on Black Blobs Appearing In Camden, NJ · · Score: 2, Interesting

    A Google search brought up several pages citing Thomas Jefferson as the source of the quote.

  9. Re:Unfortunately, they are using Ada on F-22 Avionics Require Inflight Reboot · · Score: 1

    Because for mission critical applications the US Department of Defence consider C, C++ and Java to suck.

    Partially true. In 1999, you could use C or assembler for "nonreprogrammable" systems like 8-bit controllers. I did a pair of small embedded firmware systems for fighter a/c and they were in C (and were carefully tested for bugs). Not sure about now, though the trend was to relax the Ada mandate.

  10. Re:It'd be fairly easy to change on Pledge of Allegiance Ruled Unconstitutional · · Score: 1

    Except that doing so requires an act of Congress, which (by design) is like pulling teeth.

  11. Re:Vending Machines on Greenbacks No More · · Score: 1

    Who sticks a $20 in a vending machine?

    Buyers of postage stamps and BART cards, for two.

  12. Re:Our God will Eat Your Moon! on Partial Solar Eclipse Tonight · · Score: 1

    Look here for Mark Twain's use-a-solar-eclipse-to-get-power story from "A Conneticut Yankee in King Arthur's Court."

  13. Re:5.2 is not so scary on 5.2 Earthquake Shakes Up SF Bay Area · · Score: 1

    The depth

    There was a 8+ quake deep under Bolivia, so deep (hundreds of miles, IIRC) that no significant damage occurred, except to the then-current theory about deep quakes :)

  14. Re:Story Time on 5.2 Earthquake Shakes Up SF Bay Area · · Score: 1

    At UCLA, the chemistry and geology buildings are adjacent. When I was a grad student in chemistry, a monitor was set up in the hall that showed recent nearby earthquakes, essentially what you can get online from the USGS now. A significant aftershock of the Northridge quake hit, and several graduate students (and I) RAN to watch it come up on the screen, and cheered when it did. We also learned not to trust the instant locator algorithm too much, because they moved it away from the initial location later.

  15. wawa on Computers and Cars: A Maddening Experience? · · Score: 1

    "Wawa" was also Richard Feynman's way of saying "whatever it was." See "What Do You Care What Other People Think?: Further Adventures of a Curious Character" for an example of usage.

  16. Not there for long... on Hacking the Highways · · Score: 1

    Caltrans is removing its dark green signs with reflector dots on the letters and numbers. The replacements are light green and totally reflectorized. Eventually, exits will be numbered, too.

  17. Re: partial vacuum on World's Lightest Solid · · Score: 1

    oops, omit the hydrogen part, i was reading too fast

  18. Re: partial vacuum on World's Lightest Solid · · Score: 1

    The gel walls are quite thin. Air would diffuse in and hydrogen would diffuse out, eliminating the advantage.

  19. Re:What about Blockbuster?!?! on Why Doesn't Sci-Fi Hit the Bestseller Lists? · · Score: 1

    Now, explain to me why Hollywood keeps doping films with gratuitous sex, violence & language that does nothing to advance the story.

    To draw in teenage males, of course. *dope slap*

  20. Turbonium on Nature's Building Blocks · · Score: 1

    It's not in the book but there's plenty of literature at your VW dealer. If they have been in business a while they may have a Quantum mechanic, as well.

  21. Re:Read the book... on Java Tools For Extreme Programming · · Score: 1

    Right now, work crews are doing seismic upgrades to the older Bay Area bridges, such as replacing the rivets in the west side of the Bay Bridge with bolts and replacing x-bracing with sheets (you can see this work from the lower deck).

  22. Re:Actually, not so useless... on Voyager Keeps on Trucking · · Score: 1

    Why would they name it "II" if it left 2 years earlier than "I"??

    IIRC "2" was launched first and arrived at Jupiter second because it was in a longer transfer orbit.

  23. The bank sent me some titanium sheets... on The Sexiest Metal · · Score: 2, Funny

    ... with iron oxide strips on them. Oh wait, it's really just plastic. :)

  24. San Francisco Public Pay Toilets on Best High-Tech Toilet? · · Score: 1

    Here's the city's link to a map of the current toilet locations, and a photo of one of them. Many are located near BART stations.

    http://www.sfdpw.org/sfdpw/toilet/index.htm

    BTW the tops are not bolted to the side walls. I went to a parade and some people were sitting on the roof of one, which was tilting a few inches. Probably there's a few-inches-high catch but it still looked insecure.

  25. Re:I wouldn't tak eGreenpeace's word for it. on Larsen Ice Shelf Collapses · · Score: 1

    The pH of a solution is -10 times the base-10 logarithm of the hydronium ion concentration [H30+] (not hydrogen ion concentration [H+]). A pH of 1 means [H30+] is 0.1 molar. pH values of 0 (1 molar) and less (pH = -1, 10 molar) do occur in the lab but not much in nature.
