  1. Economics of cars on 20th Century's Greatest Engineering Achievements · · Score: 2

    I just calculated the per-square foot rate of my rental unit, and applied that to the two street parking spaces outside. It comes to $1425 per space per year. The government charges $40/year for a parking permit.

    You're right, it would take some major economic changes to get rid of cars. The main one would be the adoption of capitalism.

  3. Serious Market Research time on AskJeeves Interview · · Score: 5

    OK, I've been working on this concept for a long time, so nobody laugh.

    People navigating the internet need the assistance of a friendly, helpful assistant, who will respond to questions posed in plain English (or American, etc.). By interacting with this fictional personality, users will develop a relationship which will lead them back to the service again and again (Kaching!).

    So that leads me to....askFabio.com. Rather than interact with some musty old butler, why not pose questions to a real, live hunk of man? (or hunk of woman; we should have a lively selection of celebrities).

    The idea is that, instead of expecting some helpful and unbiased advice, which is the last thing we would expect from a celebrity, users will instead gratify their need for attention by receiving virtual responses from real famous people. After all, if they're famous, they don't have to be right!

    The cunning business strategy which I will employ is to harness each celebrity's gift for self-promotion within the actual neural engine. Fabio, for instance, will slyly slip references to his own line of Harlequin romances into each response to "literature" or "paper" , or any other related term. AskGeorgeForeman.com will, of course, scarcely ever forget to mention George's line of healthy, fat-reducing grills.

    Anyone expecting more detailed information will risk losing the attention of the highly popular personality, and being relegated to a bunch of lesser-known search engines. By this method of inducement, customers will quickly learn to lower their ridiculous expectations, and contribute to healthy, growing business model!

  4. Jeeves Wodehouse: Denied by Suits on AskJeeves Interview · · Score: 1

    There was a funny article in Salon a few months ago about how, according to the marketing gurus that took over the company, AskJeeves did not, and never had referred, to the fictional character of Jeeves in P.G. Wodehouse's series of stories.

    After reading the story I entered the question "Who is Bertie Wooster" into ask.com and got back a link to the allegedly non-Wodehouse Jeeves. Fah.

    Now the link is gone. Apparently they've adjusted the intra-axonal variances on their advanced AI web interface, and now Jeeves the Butler is officially not Jeeves the Butler of P.G. Wodehouse fame. Still, for at least a brief period, Artificial Intelligence was actually more accurate than the real kind.

    Agreed. In comparing Math and CS, I quickly found that CS was more at the vocational training end of the scale, at least in its core requirements. However I did develop a nice sideline of acing CS theory courses, since they were full of 12-hour-a-day C programmers who couldn't tell abstract algebra from a hole in the ground.

    My rule for CS is: if it can't be figured out in a few hours without a computer, it can't be programmed with one, regardless of the number of 72-hour weeks one puts in.

    True, large volumes of hemoglobin, and sufficient water to support them, is a primary performance indicator. When the water-to-blood cell ratio drops too low, however, clotting and heart attacks are major hazards.

    In bicycling (and presumably other endurance sports), use of EPO to enhance hemoglobin volume has led to many deaths, and the imposition of arbitrary blood-count limits (since EPO use is undetectable). Deaths occur after races and high-stress conditions when the blood is moving more slowly and is more apt to clot.

    Major racers such as Marco Pantani have been banned from some tours due to these high levels, whether naturally occurring or not.

    It got to be sort of a hobby to build the thing. I basically figured out that the rules could be based on the seven deadly sins: greed, lust, vanity, etc., so I built the thing to look for those. Spam itself is urban-legend-like in that people tend to latch onto the same phrases and euphemisms over and over, eg "wealth building" or "I could barely afford (rent|food|clothing), until I discovered .*", or "herbal". A big one was "Dear friend". Never, ever, use that salutation.

    Two years ago I could barely afford clothing. Now I make millions every day, selling herbal anti-spam technology to my friends, neighbors, even my doctor! It's the most amazing wealth-building program ever.

    The MPAA and the RIAA have been in and out of the courts for years. If you go to the DOJ website you can find pending lawsuits regarding price fixing by "copyright societies" in Europe, and Time Warner was slapped a while ago for offering kickbacks to dealers who keep CD prices high.

  10. Memory merge kernel on Microsoft Invents Symbolic Links · · Score: 1

    A couple of years ago I was doing some reading on the Linux kernel, and I ran across a research project which did something similar, in main memory. It was called something like the "memory merge kernel", but those words are so often used together that I can't find anything relevant on google (and Linux.com keeps coming up first for no reason - blecch).

    The idea was the same - extend copy-on-write (which only works on memory copied from a fork()), by scanning for and merging duplicate pages, regardless of origin. This way if 100 users are running netscape from 100 different shells, the duplicate executable pages can be found and remapped to unique copy-on-write pages. It was supposedly very efficient, with a slight hit in overhead of around 1%.

  14. Re:Electron waveguides. on IBM Announcements on Chip Design/Nanocommunications · · Score: 1

    Um...I think we already have quantum waveguides based on long chains of atoms in a crysal lattice. They're called "wires". (I don't know, though, maybe there's a different method that's better.)

    WRT tunneling, you're correct that electrons spend a good deal of time in the "mirage" position - it's not a mirage at all, any more than any de Broglie wave is. For instance you could call the peak of the interference pattern in the classic two-slit experiment a "mirage" too since it has an high electron density.

    The speed of the electrons between foci is definitely sub-light speed. The de Broglie waves themselves may travel FTL (the same old non-locality that gets everybody excited) but as in all of these situations it's not much use.

    It seems to me if they used a pair of parabolic reflectors similar to microwave dishes, they could get current to flow between foci over relatively large distances, with no hardware needed in between (except for the copper substrate, which is already a conductor - oops). I believe that different beams could cross as well, with little interference. That would be a useful feature, since it could replace circuit traces. It's doubtful whether this arrangement would be very efficient, due to leakage, diffraction, etc., but it's though-provoking.

  15. A little legal history on Is SDMI a Consumer's Nightmare? · · Score: 1
    It's important that people understand that the record companies have a substantial record of using copyright laws to further their monopoly interests. Here's a quote from an antitrust case on music video price fixing ( I would call the RIAA a "copyright society"):
    The majors claim that under no set of circumstances could Sherman Act jurisdiction apply to their foreign conduct. However, the United States has reason to believe that, acting through various "copyright societies" and joint ventures-- including music video and "digital radio" ventures formed to conduct business in the United States--the majors may have entered into a worldwide series of related agreements designed to dominate, discipline, eliminate or extract monopoly prices from companies providing high-technology audio and music video programming services via cable, satellite and wire transmission (hereinafter "music programming") in all major geographic markets. In addition to the domestic effects arising from the operation of the American components of the alliance, it is likely that foreign components substantially affect the domestic and export commerce of American music programming companies.

    There was also a story on Bloomberg (which is down right now so I can't confirm it) a few weeks ago about a DOJ case on CD price fixing via kickbacks to record stores; I haven't found anything on the DOJ site about this, for some reason.

  16. Re:Remember, folks - the market rules! on Is SDMI a Consumer's Nightmare? · · Score: 1

    My take on this is different - Beta was better, but Sony controlled it, just as the RIAA wants to control SDMI, and the other suppliers balked. You'll notice that all the proprietary SDMI formats are "technically superior" as well.

    MP3 in your analogy is the VHS-like open standard, which is why, for instance, it has been adopted by a lot of electronics companies which have never been in the personal audio business before. The MP3 "copyright" battle is just a proxy for the format and distribution war that's going on now in the cozy electronics and music industry, of which Sony is the biggest player, AFAIK.

    (I submitted a story a few weeks ago about the big 5 CD producers being investigated for price fixing, including TWX-now-AOL; apparently no one thought it was relevant, but I see it as the other side of the same coin.)

  19. The answer is...there are lots of answers on Questions about Database Implementation. · · Score: 1

    There are books full of ways to do this for different scenarios (many vs. single simultaneous transactions, complex vs. simple transactions, fine vs. non-fine locking granularity, tolerance for data loss or transaction failure, single-phase commit vs. two-phase, etc. etc.). For each technique, a different writing process and recovery algorithm are required.

    In general the algorithms use some sort of cache to delay having to write to disk on every operation in a transaction (eg ten updates to the same block will only need one write to disk). When a transaction is finished, most (but not all) methods allow cache pages to remain "dirty" by writing the changes to a log in compressed form. Dozens of changes to different blocks can be packed into one log block, which is written in a single, atomic operation upon transaction commit - no other I/O is needed.

    The main differences among these algorithms are in how they handle the cache - some allow dirty blocks to be flushed at any time, while some only allow flushing after a transaction is committed, etc. The tradeoff is that the techniques which ar e the most flexible in caching require the most complicated recovery procedures.

    Other methods include writing all the affected blocks out of the cache on transaction commit (the method used by transmeta BTW), or even writing each transaction to new blocks and changing a pointer to them on commit (shadowing). None of these would give much performance boost in your situation, IMHO.

    If you want some more info on different techniques, I would recommend a book called "Relational Databases and Knowledge Bases" by Gardarin and Valduriez. This is a good survey of all aspects of database construction - reliability, concurrency control, query processing, and so on, and it weighs less than five pounds :-)

    San Francisco (TP) The Newspaper Industry, already beset by rising costs and an increasingly educated population, was rocked today by the announcement of a new chip which could put thousands out of work. The new Samsung "Rambus" chip will purportedly process in a single second what it takes a 12-year-old newsboy an entire morning to deliver.

    No, I think the idea is that if you spend $70000 on a deserted country road, and buy a car for which you claim no tax deductions, parking exemption, Chrysler bailout, or other government handout, you should be able to do whatever the heck you want there (as long as you post warnings to passerby who might wander in).

    I don't have any love of blanket monitoring, but frankly, I've seen enough road carnage to think that something has to give. There are already plenty of soft spots in the automobile "transportation system" that should be dealt with but aren't: government-built roads and bridges are exempt from liability, as are traffic "engineers"; the road system runs at a huge deficit (made up by local taxes in most cases); oil-rich states are patrolled by US troops for $60bn a year; hitting a car with so much as a golf club is considered assault, while killing a child with a car is legal - these are not symptoms of freedom, but rather an overblown government-industrial mindfuck.

    I doubt if any government solution would work - after all, the mass conformity and industrial efficiency engendered by the violent deaths of pedestrians, cyclists, and other nonconformists is simply too much for the gubbermint to give up - but I do think it's possible for citizens to act up for their own rights, by videotaping, radar gunning, and making citizen's arrests of traffic offenders (that's right, you have the right to arrest anyone you see violating the law - no more "sorry, a police officer wasn't there to witness a violation" bullshit. You also have the right to prosecute a case that your wimpy DA won't handle because it might upset his car-dealer political donors).

    I say forget about the government acting to protect your rights - in most cases, traffic "engineers" won't act to stop a dangerous situation until someone is actually killed or injured. In the future, traffic cases won't be based on drivers' lies and cops' prejudiced bullshit. They'll be based on video, speed measurements, and other evidence gathered by real people on the scene. Arm yourself, with video, with the law, and your own natural rights, and get out on the road.
