    Heating and burning are well-known concerns. A small sample of the peer-reviewed literature turned up by a quick Medline search includes: And so on... Even without metal, there are numerous cases of first- and second-degree burns to the wrist area, which are presumed to be due to the arms crossed and over the chest acting as a pickup loop, but the most severe burns seem to arise from resonance between the RF drive and metal loops in contact with the patient (implantable devices or monitoring wires, such as pulse oxymeters and ECG leads).

  5. Cyberiad on A Good Summer Read? · · Score: 1
    For a good time, try some Stanislaw Lem. Solaris is big because of the movie, but all hackers should really read the Cyberiad. Memoirs Found in a Bathtub is also first rate.

    Philip K. Dick is also well worthwhile if you haven't tried him. I like Do Androids Dream of Electric Sheep and A Scanner Darkly

    When you're done with Dick's mindfucks on consciousness and identity, try some other things than SF. I would particularly recommend Orhan Pamuk's My Name Is Red---a postmodernist mystery set in 16th century Istanbul (as the title suggests, one chapter is narrated by a particular shade of red)---and The White Castle (it's not about tiny hamburgers), or Nabokov's Pale Fire.

    There are also some fantastic novels about doing science in the real world, as opposed to the more fantastical stuff that gets called SF. The best of the crop is Carl Djerassi's Cantor's Dilemma, which is perhaps the best novel of science ever.

    Back to the predictable, if you really want things only about sf-geek-hackerdom, pick up Vernor Vinge's "True Names" and John Brunners' Shockwave Rider, which was perhaps the first cyberpunk book of all.

    When was the last time a coal powerplant had a catastrophic failure that endangered all who lived near it?

    Most fatalities from coal are not from power-plant accidents but from mining. Mining accidents mostly kill miners (who cares about them?), but also can kill many people who live near the mine. The 1972 flood at the Buffalo Creek Coal Mine in West Virginia killed 125 people living nearby, injured over 1000, and completely destroyed 500 homes.

    Worldwide, tens of thousands of deaths per year occur from coal-mining accidents, and that doesn't count slow deaths from black-lung and other chronic conditions that afflict miners. In India, the death rate is equivalent to one Bhopal per month. In China, around 5000 people per year are killed in coal mining accidents.

    Compare all this to the estimated 2500 deaths due to Chernobyl.

    You don't have to copy anything to infringe on a patent. I can infringe on the Unisys LZW patent by writing my own LZW code. All I have to do is use (whether by copying or by innocently reinventing) Terry Welch's algorithm during the next month in the USA.

    Similarly, if Linus introduced into the kernel either his own code or code donated by someone else (IBM) that implements any algorithms for which SCO holds patents, even if the code in question comprises completely original implementations of those algorithms, then by redistributing the kernel without a license from SCO, Linus is infringing on SCO's patents.

    No. My argument is to keep flying shuttles and keep killing astronauts at a rate of about one crew per decade. That would leave a lot more money for research. As for astronauts, they have known the risks all along. NASA and the National Academy of Science have reviewed and published the probabilistic risk assessments all along and these numbers have not scared astronauts away.

    After the last shuttle crashes, we could ask whether the research conducted on the shuttle was more productive in saving lives per dollar spent than terrestrial research or that conducted on unmanned spacecraft and decide on that basis whether to build another fleet.

  13. Good use of money? Bad use of statistics! on NASA Redesigning The Space Shuttle · · Score: 1
    The EPA has announced that they find it worth no more than $3.7 million dollars per life saved to regulate pollution.

    NASA will spend of order $100 million per life saved to make the shuttle safer. Are astronauts really worth so much more than the rest of us?

    Meanwhile, nobody seems to have noticed that the rate of shuttle losses is completely statistically consistent with what NASA has been telling us all along:

    According to NASA, the probability of a critical failure was 1 in 145 before 1998 and 1 in 245 from 1998 on. Plugging these numbers into the binomial probability distribution, we find that the probability of 2 shuttle losses by 2003 is about 16%. Most people find 5% to be the threshold for statistical significance, so there is no good reason to believe that NASA got the risks wrong based on the two critical failures!

    This is not rocket science, it's freshman statistics.

  14. Environmental cost of production on Environmental Costs of Computer Use? · · Score: 4, Insightful
    A significant part of the environmental cost of computers is expended in manufacturing the computer, before you even buy it. Semiconductor and PC board manufacturing use tremendous quantities of fresh water (about ten gallons per chip and a total of 8,000 gallons per computer), which has serious environmental consequences in the American West and in many parts of the third world. Of course, as long as the state of California subsidizes its rice farmers' water, there are more important places to complain about this.

    Also, semiconductor manufacturing uses lots of quite nasty chemicals and while the organics can be incinerated, the heavy metals are difficult to dispose of safely for the long term and there is always the inevitable discharge of toxic pollutants into the air or water surrounding the factory.

    Finally, both manufacturing and operating computers use lots of electricity, which is usually generated by plants that produce lots of greenhouse gases.

    Besides worrying about recycling, you also want to worry about all these environmental costs.

    How about error recovery and integrity checking? There are no checksums or any kind in CVS repositories, so you can never find out whether a repository file has been corrupted until you try to check out an old revision or perform a branch merge and find out that there's a broken delta in the way.

    To me, the lack of good integrity checking and error recovery is the greatest weakness of CVS. It means that you can't rely on recent backups, but must keep every CD you've ever burned of your repository.

    This kind of thing might be fine for small projects, but I don't think it's acceptable for a large project.

    OK. I think of libertarians as liberals and people like George W. Bush, Rick Santorum, and Trent Lott as conservatives. Now you've cleared up my misunderstanding. Historically, liberals were those, such as John Locke and Adam Smith, who embraced enlightenment thinking and wanted to base government and laws on liberty and rationality, where conservatives (Tories) wanted to retain God-given natural law, monarchy, hereditary station in life, etc. This translates today into liberals who want to get the government and laws out of our bedrooms and away from our liberties, and conservatives who want government and laws to enforce "traditional Judeo-Christian values."

    As Jonathan Miller once said,

    in the U.S. they have two parties, just as we [in England] have two parties. They have the Republican party, which is like our Conservative party. And they have the Democratic party, which is like our Conservative party.
    But now that I understand where you're coming from, we don't need to split hairs over political labels.

    I'm not sure what to make of your statement that you're concerned more with criminal than civil litigation. This whole thread was a about civil matters (California's laws on implied warranties). As to criminal matters, local judges and juries in the South in the 1960s accurately reflected racist community values and exonerated some awful murderers and terrorists, some of whom took advantage of the Constitutional protection against double jeopardy and sold the stories of their brutal acts to the press.

    If you think this is all ancient history, look at what local judge Edward Self did in Tulia Texas. When rogue cop Tom Coleman framed about 15% of the black population of Tulia Texas for selling cocaine in 1999 (one 57 year old hog farmer was sentenced to 99 years), Judge Self refused to admit evidence introduced by defense lawyers that demonstrated a pattern of deceit and shoddy police work by Detective Coleman. Later Judge Self lied about his refusal to admit this evidence and despite being caught lying and forced to recuse himself from appeals of the Tulia cases, Judge Self was re-elected. This spring, the cases were re-opened by higher authorities who don't have to stand for election in Tulia. Detective Coleman has been charged with three counts of aggravated perjury and all the convictions are being vacated. The State of Texas is preparing to pay the victims up to $3000 for each year they wrongfully spent in prison.

    Before you get too enamored of direct local democracy, I would recommend re-reading Federalist X on the danger of faction and the tyranny of the majority. This spring, people farther removed from the local level got involved and

    Thanks for the clarification of your political leanings. I am confused about your comments on precedent, though. You write, "Case law better serves situations in Federal and State Court where there is a much greater interest in consitancy." There are only two kinds of courts: state and federal. There is no separate "local" court. Perhaps you're thinking of county or district divisions of state court.

    As to the benefit of local judges, you may want to think again. A local judge in the Bronx recently presided over a lawsuit in which a local jury awarded $51 million to Darryl Barnes, who was paralyzed when he drew a TEC-9 on a police officer who fired first. Bronx voters favor judges who dispense Robin Hood justice.

    Similarly, local courts have made Mississippi and many other southern states "judicial hellholes" for product liability litigation according to the American Tort Reform Association. The problem here is that the voters in the court's jurisdiction tend to identify with the plaintiff. The corporations sued generally have their factories elsewhere, so it doesn't affect the local voters if jobs dry up. On the other hand, a large award can bring a lot of money to a small county. It is this abuse of discretion by local judges and juries that makes the U.S. Chamber of Commerce call for moving litigation out of local courts and into federal courts while consumer rights groups want to keep litigation in local courts.

    As to your comment, "If someone has really done something so wrong that they deserve to pay out 30 billion dollars in punative damages then they should go to jail instead," I would only direct your attention to O.J. Simpson. O.J. did not go to jail (again, your beloved local justice did a fine job with him, as it did with the murderers of Emmett Till) and punitive damages were the most justice he received.

    At the same time, the number of liability suits ending in bizarre awards is much smaller than most people think. Just as the press tend to exaggerate spectacular events, such as civilian casualties in Iraq, and make them seem more common than they are, they also exaggerate the frequency of liability blunders (absurd verdicts, excessive awards, etc.) and do not follow up six months later when absurd awards are thrown out on appeal.

    Here are some facts, courtesy of the Center for Justice and Democracy and Public Citizen:

    • 0.02% of all civil cases handled by the state courts concern product liability.
    • The defendants win more than half of these cases.
    • When plaintiffs do win product liability cases, more than half the awards are less than $27,000.
    • Awards over $1 million are most common when the plaintiff has suffered grievous injury (paralysis, brain damage, amputation) and over half of these large awards are either reversed or reduced substantially by the trial judge or on appeal.
    • Only a small fraction of a percent of all findings for the plaintiff award punitive damages. Between 1965 and 1994, there were 379 punitive damage awards in the U.S. in product liability lawsuits. Half of these awards were less than $50,000.
    • According to the Consumer Federation of America, liability suits add about 0.26% to the cost of consumer goods. This number is similar to what the National Association of Insurance Commissioners found.
  24. Re:State law and product warranties on AMD: No Grease For You! · · Score: 1
    It's a delicate balance between the inflexibility of precedent and the caprice of the individual judge. Many, perhaps most, businesses would prefer to work in an unfair but predictable legal arena than an unpredictable one, even if the latter were somewhat fairer on average. Even when you disagree with the prevailing standards, you can at least make coherent plans for risk management. When individual judges have too much discretion, liability suits become too unpredictable to plan for. Managing an uncertain risk can easily cost more than managing a greater but more consistent risk because what kills you in financial risks are the tails of the distribution (That's why Long Term Capital Management averaged a positive return on investment in 1998-1999, but went bankrupt in 1998 because of very improbable fluctuations.)

    Conservative thinkers tend to prefer slow change and predictability, which is why they push for mandatory sentencing laws, caps on civil awards, and other measures to limit judicial discretion. Since this nation is strongly conservative at the moment, you may have to wait some time before liberals return to power and push for greater judicial independence.
