  1. Re:But the cost? on WD Builds High-Capacity, Helium-Filled HDDs · · Score: 1

    That's trivial to compensate in the head actuator. Those actuators could provide way more actuating force for faster seeks, but performance is limited by turbulence (among other things).

  2. Re:Why not a vacuum on WD Builds High-Capacity, Helium-Filled HDDs · · Score: 1

    Hopefully they designed their housing so that the helium will stay put. Alas, don't forget that such migration is a two-way street. If the pores are large enough for helium only, then the only thing that can migrate back is helium as well. Although the obvious problem will be that the partial pressure of Helium in our atmosphere is very low, and that partial pressure will equalize with internal pressure of the hard drive -- someone correct me if I'm wrong, please.

    That's assuming that the seals are only permeable to helium. When the seal breaks, it'll of course be permeable to anything. A hermetic enclosure means completely gas tight, helium included. I have no idea how they deal with wires. Glass frits?

    I have to agree. Maybe my car looks like a pile of crap, but it drives sweet, and is in better shape mechanically than when it left the factory.

    A self driving car, is, you know, self-driving. The developers of the safety-critical software are the only ones who can be held liable for it running over someone.

  7. Everyone misses the elephant in the room on MP Seeking To Outlaw Written Accounts of Child Abuse · · Score: 1

    The problem is awfully simple: the MP is, most likely, lying through his teeth and he damn well knows about it. If he claims that "[such writing] fuels the fantasies' of offenders and could lead to the physical abuse of children", he better have it as established view in relevant disciplines, backed by papers, and not something that just came up (if even that). Alas, this "view" of his is just a fantasy, something he made up.

  8. Re:I hate Odds Ratios on Scientists Themselves Play Large Role In Bad Reporting · · Score: 1

    Wait a minute: how the heck OR 20:1 implies probability ratio 3.5:1? The probability of event A is 1/21 = 0.048, probability of B is 20/21 = 0.95. The ratio p(A)/p(B) = 0.051 or ~1/20. It's seem that the OR approaches probability ratio as the OR goes away from 1:1. It's seem to me that OR is farthest away from probability ratio when OR = 1:1. Or else I'm not getting what you mean by OR 20:1 implying 3.5:1 probability ratio. Probability ratio of *what*?

    I know they didn't engineer it that way, but no matter what battery pack they'd have used, it'd end up with the same problem. So blaming it on Ni-Cd ain't it.

  11. Re:Who Cares on What's Next For iRobot? · · Score: 1

    I agree. When one talks about large format, film wins. But you can't really hold those in your hand for very long ;) I have a russian 60x60mm ripoff of the Hasselblad and that thing is certainly good in place of a brick in case you needed to bash someone's head in. I think that cameras that are meant to be carryable on a neckstrap (or wriststrap) are a different class from anything big format. I'd think it's a tad unfair to even try to compare a dSLR to anything large format. It's like apples to apple wine ;)

  12. Re:Build a better Roomba? on What's Next For iRobot? · · Score: 1

    The Roomba battery is either subject to a larger discharge current per unit volume, or is not properly managed during both charge and discharge. Usually the latter. There's no technical reason at all to have a battery-powered appliance that won't properly work with one or two dead cells in a battery pack (save for shorter discharge time).

  13. Re:Who Cares on What's Next For iRobot? · · Score: 1

    What's so special about film? At least for high sensitivity uses, digital pretty much wins. Even PowerShot G1X has less noise at ISO 1600 than the best color film would, AFAIK. Professional DSLRs, I'd think, bury film when it comes to pretty much everything, don't they?

  14. Re:Roomba sucks (but not in the way I paid for) on What's Next For iRobot? · · Score: 1

    A NiCd battery pack is not the problem. The problem is the charge-discharge circuit. If you do charge balancing on both charge and discharge -- and that requires doing individual cell monitoring and shunting -- a NiCd has life quite comparable to NiMH.

    80%?! That must be some poor school district you're talking about. A nearby school district gets 90% of money from income tax and state tax reimbursement (that's not money tied to particular performance). They get remaining 10% from federal and state foundation money. Only those 10% is money tied to performance or otherwise with carrot and stick ties.

    Well, if the "true meaning of OT" is so radically redefined in NT, then perhaps we can apply the same thinking to the NT, and say, like, it's all really meant all differently. IOW: It's all pretty silly, if you ask me.

    Feynman would have nothing to do with his origins/ethnicity. He refused being included in a book about "great Jewish men" (I paraphrase), and he'd be probably quite offended by you using his name in this fashion. Yes, what you cite is a fact, but the argument is charged, and he'd want nothing to do with it I bet.

  20. Re:Not computers needed on School Regrets Swapping Laptops For iPads · · Score: 1

    It's perhaps time to change those funding rules. IMHO school districts should choose their own way and stop being slaves over money. Fuck federal and state money, that's only there so that the state or the fed can lead you around with a carrot stick (you stick to their rules, they pay, you don't, you don't get paid). A typical school district should be only running off the local property taxes. That would simplify the finances a whole lot, even if it's less money to begin with. It's fix this general-vs-other-fund problem. Even then, having split funds isn't all that great. The principal and the district should be able to allocate money as they see fit in the circumstances. If one year they've got a building to fix they should be able to trade off, say, an art teacher for a year.

  21. Re:Not everyone needs to be IT literate. on School Regrets Swapping Laptops For iPads · · Score: 1

    Everyone not knowing the basics of how a car or a microwave works costs them money. Real money. Mindboggling amounts of money. Knowledge has value measured in hard currency not merely because you get a better job, but because you won't be ripped off at every opportunity in your life. My neighbor was just quoted $1800 (USD) to replace a $35 A/C compressor clutch plate in her F150 truck. It's a 10 minute job, and that time includes washing your hands afterwards. The damn thing is held down with a single small screw, and you don't need to take anything else off to replace it.
