  1. Re:Expected fallout from the Beowulf takeover on On the Supercomputer Technology Crisis · · Score: 2, Insightful

    This is an expected and predicted fallout from the recent rise in popularity of beowulf clusters. Slowly but surely managers are realizing, yes, it is possible to have a supercomputer on mass-market hardware, running a free OS.

    Don't see this as bad news... it's a sign that we're winning.


    Not necessarily. There are plenty of computational problems that, so far, do not lend themselves well to parallelized solutons.

    The point of this post and the linked article is that the hype about Beowulf and similar cheap, cluster-based technology has caused mainstream technologists to overlook the need for traditional supercomputers like the Crays.

    That indeed is bad news and a sign that computer science in general, while not necessarily losing, is not winning.

  2. Re:Smart idea! on Seagate Ups Drive Warranties To 5 Years · · Score: 1

    How many people will endure the hassle of warranty repair on a 3-5 year old hard drive, when they can pick up something significantly bigger and faster?

    First of all, they might replace your 5 year old drive with the latest model that's substantially faster and larger. So the warranty repair might be worth the trouble.

    Second, there are some situations where you want a replacement drive that is identical to the original, e.g. RAID.

    This is just an attention (advertising) ploy. Sure, you could use urine, but it would be stupid to do so, since the salt and urea in urine would increase dehydration.

    To the chem geeks out there, a question for you: Is there some chemical we can add to our urine to take out the urea and salt? There must be something that would cause it to turn into a precipitate or something, no?

  5. Re:Check the Expert. on Experiences with Laser Eye Surgery? · · Score: 1

    Umm... No. It's not eye muscles getting weaker, it's the lens getting less pliable.

    Perhaps the lens does indeed become less pliable, but muscle weakening due to age is definitely the primary factor in age-related far-sightedness. This muscle weakening is part of the general loss of muscle-mass associated with declining levels of growth hormone -- a process that is well-documented as reversible by administering human growth hormone supplements.

  7. Re:Disease damages motor functions.. on Macaque Monkey Goes Totally Bipedal · · Score: 1

    [thesis that the advantage of the two-legged walk for people is that it is lower-energy ]

    Care to back that up? Last time I heard there was no consensus amongst investigators on how we ended up walking upright entirely.

    Just because there's no consensus on how it came to be does not negate that it is advantageous. That the upright body position allowed by bipedal locomotion is more efficient should be fairly obvious. Your torso rests stationary on a vertical spinal column -- minimal muscle effort is necessary to maintain balance and posture, rather than support your mass against gravity. This doesn't hold true at all for a horizontal body position supported by four limbs.

    Well, by those definitions anything could be a sport/game. Toenail clipping. Deck sanding. Dwarf throwing.

  11. Re:Expensive Hobbies on Build Your Own Model B-52 · · Score: 1

    How would you feel if you crashed and burned that poor B-52? I bet they have their best damn RC pilot at the helm when they fly that beast.

    I would guess that a model like that would be easier to fly than most smaller ones, precisely because its heft lends it stability (especially in windy conditions). Plus you wouldn't be hotdogging the B-52 the way you would with acrobatic models. So while the consequences of a crash are much greater, the likelihood of it occurring is lower.

    And with eight turbines (which are much more reliable, once running, than piston engines) going, the likelihood of catastrophic power loss is almost nil.

    As a 48 yo grandmother, I am offended that technical incompetance is equated with being a grandparent. I don't think anyone would have said "so simple even my grandfather could implement." I am incidentally, a C programmer of 20+ years.

    Are you offended because you categorically dislike generalizations, or because you disagree with the validity of this particular generalization? If the former, I'd say you've got some emotional issues to deal with. If the latter, you need a bit of a reality check. There are exceptions to every rule, but the exceptions don't necessarily negate the rule.

    After a lot of hand-wringing and head scratching we concluded that the reason they are stealing is because they feel that at $6 an hour, the company is stealing from them.

    Time to revisit this Fortune Magazine article again.

  16. Re:Damn, where do you stay? on Social Engineering in the Workplace · · Score: 1

    I've lost my card on a number of occasions (usually only to find it later hidden in the depths of my wallet) and they *always* prove that you are who you say you are.

    I wonder if this reflects national differences. I also travel a lot, but mainly in Europe, Asia and Canada. Honestly, I cannot remember a single occasion where I had to show identification to get another keycard.

    Maybe it's also because I tend to stay in snooty, high-end hotels where the consequences of staff offending the guests are higher.

  17. The real problem -- do we value trust? on Social Engineering in the Workplace · · Score: 4, Interesting

    Social engineering isn't rocket science -- it boils down to exploiting the trust that exists between people. Smart-alec geeks and slashdotters seem to take pleasure in pointing out how stupid victims of social engineering are. Granted, many social engineering schemes are successful due to mere ignorance. But is it inherently stupid to trust people? Here's the problem: there are costs and benefits to an environment in which people don't trust each other.

    Yes, this Israel fellow demonstrated very well what happens when people trust each other too much, but what happens when you take it to the other extreme? You end up with stories about like Walmart where employees are locked in to prevent theft and can't call an ambulance when the forklift rolls on them. Some might think that it's worth compromising on a theft rate of, say .5% if it means being free of stifling bureacracy and draconian security. Given that, trusting each other is a choice we make because the risks it entails is, on the balance, worthwhile.

    That's why, for example, hotels generally don't ask you to show ID when you claim you've lost your room key. If they did, they'd suffer more lost business than the cost of insuring against the occasional theft of a guest's belongings.

    Everything is a compromise.

  18. Re:Of course... on The Logic Behind Metric Paper Sizes · · Score: 1

    I lived in england a few years ago when the system changed in all the stores. I almost didn't notice it happen. Same with the euro conversion in the Netherlands. It was fun for a few days then noone thought about it anymore.

    Some changes go smoothly because changing isn't actually a big deal. Other changes go smoothly because society at large realized that it wasn't a big deal and so put a hell of a lot of effort into preparing for the change. That's the case with the Euro switchover and UK going metric. I'd hardly describe the process as "painless".

    On a side note, the Baja Beach chain of clubs is by far the most fun I've ever been to. Mind you I went to the ones in the Netherlands, but I'm pretty sure they're all built around the same model.

    Basically, the theme inside the club is that it's a beach resort. Fake palm trees, fake sand, etc. And the best part? The hosts and hostesses are all super-buff hotties wearing thongs. There's plenty of beefcake for the women and hot flesh for the men -- they literally walk around with only dental floss covering their bodies, selling you drinks on the dance floor. If you're willing to fork over extra money, you get a "body shot" where you drink your drink off the body of the hostess -- although that part grosses me out when you consider who else has licked there. And about every 15 minutes the hosts and hostesses get up on top of the tables and alternate between a male and a female striptease!
