This actually helps the little guy, because they can issue the sell order that night when they get the news and get treated the same as the guy who has his HFT software following the AP twitter feed.

    However, simply executing trades monthly would not be sufficient. You'd need to randomize the time that trades are executed and have them run without warning. So, at noon GMT+5 on the 15th of the month plus or minus a fudge factor with a standard deviation of n hours everything in the book executes. If you don't have your order in the book, you wait another month. If the time is known, then what will happen is the book will be empty until about 3 microseconds before the trades all execute, and then the book will have 35 billion entries in it. It would eliminate day-trading, but not the advantage of institutional investors.

  12. Re:Israel airport security on TSA Accepting Public Comments On Whole Body Airport Screening · · Score: 5, Insightful

    That is definitely an issue. Israel only has two international airports, and spends quite a bit of money on security in general, with every citizen serving in the military.

    That makes the entire society far more security conscious, and military training means that people know how to follow procedures and generally stay alert. The fact that everybody serves in the military also means that the guards are diverse and not just those who couldn't find a job or get a scholarship.

    The result is that a security program that works in Israel will not necessarily work in the US, and certainly not with bottom-dollar security guards.

    Also, Israel has a lot of defense in depth. Maybe the airport security isn't as tight, but they have far more border security at drive-in points, and even checkpoints at places like malls. All of this makes it a lot harder to get weapons to the airport in the first place. There is also a much higher state of vigilance - when bombs have been planted on buses in the past they've generally been noticed resulting in immediate evacuation before they go off.

    I wasn't talking about upgrades in the sense of replacing components, but outright replacement. My point was just that PCs have a lot more longevity.

    A PC from 2002 is still pretty usable today, and can run XP with full security updates. I suspect it would run Win7 reasonably well, though it would be getting a bit outdated. However, we're talking about something 11 years old.

    Contrast that with a 4-year-old Android phone or even iPhone. An iPhone from that era stopped getting security updates about a year ago most likely, and an Android phone from that time stopped getting updates several years ago, assuming it ever got them.

    Right now you can buy a PC and get 5-10 years out of it if you don't play games and such. Tablets are largely designed to be obsolete in 2-3 years, and they aren't cheap (the cheap ones are practically obsolete while still on the shelves).

    Honestly, I'm not sure if that is going to matter to the average consumer or not. However, when people decide to not upgrade their PC and get a tablet, and find that in 3 years they're still using that non-upgraded PC but the tablet doesn't run the stuff they need to run, they might think twice about upgrading the tablet.

  16. Re:Dell poisoned their brand on Blackstone Drops Dell Bid, Cites Declining PC Market · · Score: 5, Insightful

    They once had an appealing brand, which gave them an advantage over all the other people who were selling an indistinguishable product.

    The reason Dell became big was because of really good just-in-time manufacturing control.

    The biggest selling point for computers back when Dell became big was the CPU and its clock speed. It was also the fastest-depreciating component of the computer. In order to get good prices you needed to buy them in bulk, but if you stockpiled them and then took six months to sell them you'd be wiped out by the depreciation (you pay $1000 for a CPU that is worth $300 in six months).

    Dell did build-to-order, mail-order, and just-in-time extremely well.

    Build-to-order means that you don't end up with 47 models where you end up with 10 that don't sell well and have to be sold at firesale prices. It means that each customer gets exactly the computer they want, at the lowest price possible for that computer (well, assuming they want to buy a copy of Windows and MS Works). Their very-friendly website meant that people didn't have to walk down rows of PCs at the local retailer and try to compare the 47 different models their competitors were selling.

    Mail-order means that they had little warehousing/distribution, which means less PCs stuck depreciating in the pipeline between consumers and the manufacturing plant. If they didn't sell as many model 3 video cards they just didn't order that many - they didn't have 30,000 PCs with those cards sitting in stores all over the country depreciating.

    Just-in-time means that the part comes in from Intel/etc the day before it gets mailed out as part of a PC, or close to it. Again, inventory is rapidly depreciating, so you don't want to sit on anything. They were able to react to changes in the market - they didn't have a stake in one model or another selling better - they could just go where the customers were. If they offered a particular model and nobody bought it they didn't lose much, because they didn't build it until somebody ordered it.

    Things like this are what made Dell big. Everybody else figured out what they were doing, and the MHz war wound down making the CPU less critical and slowing down depreciation.

    Note - I'm not particularly close to the PC hardware market, so if there were other factors I'm all ears.

  17. Re:I'd have been pissed. on Statistical Errors Keep 4700 K-3rd Students From NYC 'Gifted' Programs · · Score: 1

    Precisely. Sounds like they need to go back and review their methodology. And probably put off the assessment until later on.

    The issue here is that no matter where you draw the line, and how you draw the line, there are thousands of determinations that would change if you moved the line even the tiniest bit in either direction.

    They were calculating to the month, and not to the day. Now they're calculating to the day, and not to the hour - I bet that affects quite a few determinations. Then we draw the line at 97%, and not 98%, or 96%, or 97.1%.

    The label "gifted" in many states really just means "individualized" - some part of the whole is treated as exceptional, and thus they get instruction tailored to their actual performance and not just their physical age. For what we spend on education I don't really understand why this couldn't be extended to everybody. When you're testing for IQ/etc all you're really trying to do is test somebody in a way that can measure performance across a very wide range. If you just performed that testing at regular intervals for everybody, combined with testing on mastery of the material being taught in class (what we traditionally test), then you could get a sense for whether the student should be placed higher or lower than they are, and their class assignments can be adjusted accordingly.

    When I was in Elementary school I had fairly mediocre performance, and before I was identified as gifted I had a lot of attention/discipline issues in class. Even identified as gifted the reality was that little was done to actually accelerate classwork for gifted students - they just got some special instruction once a week but stayed in regular classes. It wasn't until middle school and especially high school when classes were tracked to varying performance levels (especially in high school where the more college-like schedule meant that you could mix/match across grade levels and subjects). Once I hit those grades my performance was exceptional in areas.

    If a kid is really gifted at some subject then even in 2nd-3rd grade they should be allowed to advance accordingly. If they've mastered 4th grade math when they're in 2nd grade, then they should be taking 5th grade math, and then 2nd grade english or whatever. If they're behind in math then they should be taking 2nd grade math when they're in 5th grade. The way we deliver instruction needs to be more flexible. This isn't about leaving children behind - it is about not tossing them into classes where they won't learn anything anyway, so that in the time they are in school they learn as much as possible and don't simply graduate with a meaningless diploma.

    This is e-ink, that's the whole point. I believe e-ink is generally B&W and definitely has slow response time, which is why vendors haven't been investing as much in it. If you want a 7" HD color display, just get a Nexus 7.

    The point of e-ink is that it is particularly well-suited to reading books. The refresh is no big deal since you only flip a page every 10 seconds or so (or less), and the fact that you can just plug it in about once a month to recharge makes it very much like a paper book. The displays are passive and rely on the fact that the e-ink has contrasting reflectivity when on vs off which means that it works just as well under a 60W or 375YW light source. The passive display also reduces contrast vs ambient lighting, which makes it much less annoying to stare at for hours at a time.

    Bottom line is that if you like to read, chances are that you're doing it on an e-ink reader today. If you don't like to read, chances are you don't grok them. Just about anybody I've talked to who is a heavy reader has opted for the e-ink displays. I own one, and I don't even consider myself a heavy reader (I prefer unabridged audiobooks).

  19. Makes sense. Plus, far more effective at the close ranges involved in home defense, shot loses effectiveness quickly and doesn't penetrate walls if you use the right shot. Aimed at a doorway or down a hallway it would basically take out anybody in the general direction, which gets rid of the need to aim (but NOT the need to identify your target - which is the key problem with defending yourself against a nutjob who doesn't have the same constraints).

    Things like assault rifles really only make sense for hunting at range.

  20. I know they make pistols with biometric locks on them. What I don't get is why they don't make shotguns equipped in the same way. A shotgun makes a lot more sense from a self-defense standpoint, and a biometric lock helps mitigate the stolen weapon problem (at least if the thief is in a hurry).

    If this guy were running around in my backyard I wouldn't mind having a weapon for self-defense. I'd certainly be content to lock the doors and leave the apprehending to the professionals, but if the guy decides to break a window to take shelter in my home I'd prefer to not have to rely on the hostage negotiators. Sure, I might get surprised and then I would just have to surrender and hope for the best, but if I could take shelter in a defensible area and call the police a shotgun trained on the door would make me feel a whole lot better.

    That said, rare situations like this are really the only ones where I'd really want to have a gun, and the reality is that this guy isn't going to be moving around the city freely as long as the police are out in force. I wouldn't want to rely on a gun except when I'm alert and awake and have some warning. While my emotions say that having a gun nearby when I hear bumps in the night might be comforting, I'm not sure I'd trust myself to apply good judgment in such a situation. Also, a gun is a liability in the present legal climate, where any use of a weapon even in your own home for defense is second-guessed. The odds are that the gun will cause you more trouble than it saves you.

    One thing I will say about having a gun is that you shouldn't own one unless you're fully prepared to kill somebody with it. If you aren't then at best it is a waste of money, and at worst it will cause you a lot more harm than good.
