  1. Fish - on a train? on Old Subway Cars As Artificial Reef · · Score: 1

    How long do you think it will take the fish to work out that the train is out of service? If they are all experienced AMTRAK passengers, it could be a very long time.

  2. Seems rather silly on FCC, FAA Still Don't Want Cell Phones on Planes · · Score: 1

    The two places for which a "cell" phone seems perfectly named are in the local police lock-up and in the back of a plane, and they won't let you use one in either.

  3. Re:Patent Link on Multi-Channel Communication Patent Up For Sale · · Score: 1
    It really does not cover P2P either as there the data does not go back through the server. They are only claiming a back channel to a server.

    As well as SETI@Home it looks like distributed.net (http://www.distributed.net/ ) had been in business for 2 years prior to the filing of this patent doing exactly what is claimed for RSA decryption. So shooting it down should be easy.

    You need to transfer a 4Gbyte file. Your Internet connect speed is 256Kb/s. How far must you be transferring the data for it to be faster to transfer it via your connection rather than via a man on a bicycle carrying a thumb drive?

    This used to be a standard exam question when I taught CS, only back then he was only armed with a floppy. As floppys got larger faster tha bandwidth increased (back then it was proabbly 2400bps dialup) the poor guy kept having to ride further and further.

    Lets see - the file will take 8*4x10^9/256x10^3 (back in asynch dialup days that multiplier was 10, not 8) = 0.125x10^6 seconds. Lets suppose the bicyclist average 10 miles per 3600 seconds. So break even is 10*1.25x10^5 /3.6x10^2 ~ 4x10^3 (4000) miles.

    For extra marks: How large a thumbdisk would a swimmer need to carry from Florida to Cuba so that the transfer rate would be faster than the entire bandwidth of the island? There are no extra marks for speculating where the swimmer would carry it.

  7. $330 each! on Jimmy Wales Faces Allegations of Corruption · · Score: 1
    I hope he got a note from is manager advising him to eat more cheaply. No wait ....

    I once managed to spend $90 per head in a steak house directly opposite the Opera House in Portland, OR. For that we got a very large steak, a poor quality baked potato (no texture) and broccoli! Won't go there again. I figure we paid $35 each for the meal and $55 for the nice white linen tablecloth and general ambience (of which it had lots because it was almost deserted even immediately after the Opera).

    But that wasn't on expenses, thank god.

    Congratulations!

  9. Earth based variations? on More Spacecraft Velocity Anomalies · · Score: 1
    The statement that the effect is less for symmetrical about the equator flybys and greater for asymmetrical ones suggests some systematic error in the measurements.

    They are talking an descrepency of 1 part on 10^6. As they say its absolute value is 1.3x10^-2 that means the relative velocity is 1.3x10^4. So boost (which is down around 10^-10) is not a factor.

  13. Re:Not the same as Chinese Test on US To Shoot Down Dying Satellite · · Score: 1
    If they don't shoot it down all the pieces will re-enter, no almost about it.

    As for the fuel, I expect you mean plutonium. No propellant is going to make it to impact. So the question is - do you want to spread very small concentrations of plutonium over a wide area where you can't clean it up or have to go find a few concentrated dollops after impact, like they had to do in Canada.

    Seems rather like the Quentin Crisp approach to re-entry management to me. Don't lose your nerve - after 5 reentries it won't make any difference!

  14. That's not how its done on Does Anonymity In Virtual Worlds Breed Terrorism? · · Score: 1
    They are actually communicating using conservative talk show call-in lines.

    They encode their message in words of more than two syllables. That way its perfectly secure - they don't even have to encrypt - no other listeners understand what they are saying.

  15. Carbon footprints? on Sci-Fi Tech We Could Have Right Now (For a Price) · · Score: 2, Interesting
    $70bn really is not that much money - less than the Iraq war is costing us every year.

    But I wonder what the carbon footprint looks like? A plane at 35000 feet is in much thinner air and would not be able to fly LA to NY at a much lower altitude. The train will have to work in that thick air but will be a lot longer with presumably many more passengers and is not using aerodynamic lift. The propulsion system is also more energy efficient.

    So I have no idea which works out better. Anybody have numbers? One can of course argue that the maglev can use renewable energy, but that's a crock unless you have surplusses of renewable energy, which we don't.

  16. Re:Science and reporters... on News Of SETI Signal Just Bad Reporting · · Score: 1

    I've seen other scientists carefully explain things to reporters only to have the report totally screwed up, and I have had it happen to myself, but never in such an amusing way. Normally its just depressing, especially as they usually make you look like an idiot in the process.

    The idea that we might all be chewing on the same steak is rather off-putting.

  19. Did the summary writer read the article? on Congress To Investigate FCC · · Score: 2, Informative
    I think not.

    The article says Congress is investigating the FCC for being too close to the industries they are regulating, giving them an inside track to getting favorable decisions.

    It goes on to say that the companies are pissed off because of the decisions they do make. What that demonstrates is that the companies would like even more influence over the decisions the FCC takes. It does not mean that Congress is investigating the FCC to make it so.

    If the article is to be believed, Congress wants to make it harder for the companies to manipulate the FCC, not easier. If so, the companies will not be rejoicing over Congress's actions.

    If we attach the front of the line to the back of the line - which won't need too many more of those tape barriers, the line can go round and round as fast as people can walk.

    As people tired, you would pull them out of line and send them onto planes so that they would not be slowing down the line. We already have separate lines for people with disabilities so that's not a problem.

  23. This thing will land in Tokyo? on How We Might Have Scramjets Sooner than Expected · · Score: 2, Interesting
    That's amazing. As well as fast it appears to be VTOL. On current planes you have to fly into Narida and then take an almost hour long ride on a fast train to get into Tokyo. So its going to take around 2 hours on a good day to get from landing at the Airport to stepping off the train in the bowels of Tokyo Station.

    Of course, there's a trade-off here. In order to go real fast you have to get real high, and to do that you have to go real fast (or follow a ballistic trajectory, which would require you to drink your Chateau Lafitte through a straw). So perhaps there is an economically feasible envelope up at around Mach 5 and 100,000+ feet - Concorde pretty much demonstrated there was not one at Mach 2 and 60,000 feet and presumably this one will be even more capital intensive.

    What it does for global warming is another question - you might have to only fly them during the day.

  25. Is there a prize for worst written summary? on Voyager 2 Set to Reach Termination Shock · · Score: 1
    This summary has to be a finalist.

    First it tells us twice that the solar wind falls below the speed of sound at the termination shock. Surely saying this once would have sufficed. Even in Montreal where they like to tell you everything twice they at least do it once in English and then again in French.

    Then it goes on to claim that the terminator wobbles both in time and space. What the heck does that mean? How can something wobble in time and space?
