  1. Common response: blame the user on The Enterprise Is Wrong, Not Mozilla · · Score: 1

    The millennium bridge sways because people are walking incorrectly.

    You're holding your phone wrong.

    A common response for engineers and software developers is to blame the users for doing it wrong. Usually the users win. No matter what, though, the developers lose.

  2. Re:Also a pony and a flying car for everyone. on White House To Announce IT-Powered Smart Grid · · Score: 1

    You should read up on adaptive impedance matching in smart grid, also known as Volt/VAR optimization. Also, you should know that load shedding, like not running pool pumps for an hour during peak load, can delay construction of new power plants as well as investments in the T&D network infrastructure to reduce congestion. This stuff really works, and economic benefits can be built in so that customers will choose to take advantage of load shifting programs.

  3. Re:Not so safe on NASA Rejoins Space Race With Manned Deep Space Craft · · Score: 1

    Well, the shuttle has about a two per cent death rate per astronaut flight, and a failure rate of 1 in 65. (130 missions with two failures.) the OP is not that far off, and there was a time when the failure rate was 1 in 50, but there have been successful missions since then. Who knows what the final failure rate for the shuttle will be?

    I tend to agree with the OP that using the shuttle as a benchmark for safety is a great way to make a high risk activity sound safe. What sounds better: 10 times safer than the shuttle or 1/100,000th as safe as air travel? NASA is lying with statistics.

    The risk of an accident is low, but the consequences for the Swiss would be high. An 80 kilometer exclusion zone would cover over 10% of the nation's land mass.

  7. Re:Nuclear economics on 30 Years To Clean Up Fukushima Dai-Ichi · · Score: 1

    Nuclear power has never been economic.

    I sort of agree. US$12 billion divided by the amount of energy produced by Fukushima is one or two cents per kilowatt hour. I think the estimate is low, because nuclear engineers have cost underestimation down to a science, and because "cleaned up" has different meanings for different people. You wouldn't live for a year at a place of my choosing on a site that the nuclear industry claims is "cleaned up". Nonetheless, if you assume that every nuclear plant meets this end, it probably doesn't double the cost of the produced electricity.

  8. Re:How does this compare? on Japan Reluctant To Disclose Drone Footage of Fukushima Plant · · Score: 1

    I have heard a recording of an official during TMI, and two things struck me. First, he was not a "spokesperson". He was the real guy, and it felt almost embarrassing to listen someone so unfamiliar with how to "play" the press. Second, his candor was striking. When he didn't know something, he openly said that he did not know it. How times have changed.

    Actually, an operator's job is pretty similar to a commercial pilot's. They work to get it up and running. They work to get it down and stopped safely. They risk everything helping strangers in the event of a disaster. The rest of the time, the job's pretty dull.

  10. Don't trust Chrome with more than $20k on Hack Chrome, Win $20,000 · · Score: 2

    What I get from this is that Google is so certain of Chrome's security, they're willing to trust $20k on that security. The lesson you can take from this is not to do anything with the Chrome browser that would put you at risk of losing more than $20k. After all, the authors won't risk more than that. Of course, other authors are even less certain of their browser's security...

  11. Astrology has testable hypotheses but doesn't test on Bombay High Court Rules Astrology To Be a Science · · Score: 1

    Astrology does have a few testable hypotheses (i.e., that an individual's personality traits are correlated to the season they were born in, and that an individual's behaviour in any given season is related to the season in which they were born). However, it's clearly not a science in that it doesn't really test those hypotheses in controlled experiment to establish the predictive power of the theory of astrology. If astrology was rigorously scientific in its approach, then there would be research in areas like southern hemisphere vs. northern hemisphere star signs, not to mention psychological research into refining what effect birth season has on personality traits.

    Just about every astrologist is completely out to lunch, as well. Even the most striking imaginable correlation between birth season and personality would not permit quotidian predictions of how your day is going to go.

  12. Re:Toaster? on Solar Car Speed Record Smashed · · Score: 1

    Very few humans are capable of generating a kilowatt, and none of the ones that can do it are capable of doing it for 40 seconds (1km / 88km/h). Typically, people consume about 100 watts in food power. Generating ten times that power (mechanically) using just your legs is hard and unsustainable.

    So, you're saying that an engine incapable of generating 1kw can't push the test car as fast as an engine that is capable of generating 1kw at the drive axle (FTFA: 1050w * 0.98). Yes, you are correct.

  16. Re:DRM is just a delay on Intel Insider DRM Risks Monopoly Investigations · · Score: 1

    There is always a time when the signal is unencrypted, because our brains are not capable of decoding the encrypted signal if it's displayed on a monitor that way. It would just look like noise.

    Certainly, it can be made really, really hard to get at the unencrypted signal by doing the decryption inside the display device, but that will not prevent access to the unencrypted signal. It will just be a real pain.

    When I first read Schneier's Cryptography, I was absolutely blown away by the idea of a zero knowledge proof of knowledge. I thought it couldn't possibly work. What the *AA is looking for is a zero knowledge transfer of knowledge. On its face, that's impossible.

  19. Re:Science on Researchers Race To Recover Radioactive Rabbits · · Score: 1

    Despite the common belief and what bad scifi would tell you, rabbits (and other things) don't become radioactive when exposed to radiation.

    In this case, the rabbit likely consumed radioactive materials, meaning that it is contaminated with radioactive materials. The rabbit itself, though, is not radioactive.

    This is true, but it's only a kind of half truth. If the rabbit has consumed some strontium-90 then the skeleton of the rabbit will incorporate some of it. Strontium and calcium are both in family 2 on the periodic table and only one period apart, which means that they are chemically similar. Sr-90 is a pretty common component of waste from old uranium and plutonium fission because it's about half the size of U-235 and Pu-239 and it has a relatively long half life (~30 years). According to wikipedia around one-quarter of the ingested Sr-90 could be retained by the rabbit! This is definitely something they will want to contain to prevent spreading of a biochemically dangerous isotope.

    Sr-90 is one of the most dangerous beta emitters because after incorporating the Sr-90 in your bones, you are guaranteed to absorb the beta emission. As long as you're still alive, I guess. It depends on your definition of "you".

    The radioactivity is not contagious and the fear is not that someone will pet the radioactive rabbit and become radioactive themself. The problem would be if a hunter caught the rabbit and ate it. Then he/she would ingest both the rabbit and the radioactive materials, putting him/her at higher risk for certain diseases (most notably cancer). However, he/she would not be radioactive either.

    This really only touches on a part of the problem. A rabbit can go a long way in a short period of time, pooping all the way before finally expiring. It's not as bad as Sr-90 getting into a waterway, but it's pretty bad.

    If they raise $100K, that's starting to get into the range of reasonable contracts to have great orchestras record 26 symphonies with named-above-the-orchestra conductors. Even if Naxos has a kitten over this and starts to strong-arm, $100K will turn some heads.

    Should you choose to part with three CDs worth of your hard earned money - $50 - that will get you a dvd of everything musopen has ever recorded in this way. Lossless.
