  1. Standard ./ line on Khan Academy: the Teachers Strike Back · · Score: 0

    But I thought that the standard /. line was to teach to the highest student and pull the rest along. . . . .

    Actually, that's the standard teachers union line, where the fast learning kids get to teach the slower kids instead of learning farther ahead themselves. This makes them more manageable, and keeps everything on a nice grade-level basis so the teacher can read the lesson plan a week ahead of having to teach the lesson, instead of knowing the material cold. This is why it's possible for the P.E. teacher to substitute for the History teacher on occasion.

    I think the standard /. line, if there was one, would be: let the faster learning kids learn at their own pace, and let the slower learning kids learn to say "would you like fries with that?" to the faster learning kids.

  2. I'm pretty sure the newer ones aren't as safe on Would You Trust an 80-Year-Old Nuclear Reactor? · · Score: 2

    The newer ones were built in a much stronger regulatory climate, which is not to say a much more stringent one, but instead one in which the regulations were constantly changing during construction.

    As a result, newer plants have a lot of "engineering modifications" on top of their original designs, and every one of those modifications is a potential point of failure because the system was not considered as a whole when the regulation was decided, and the minimum delta necessary to comply with the regulations is what will have been done instead. This is generally called 'regulatory hurdle jumping', and it's pretty typical of any large construction project that's actively opposed by one or more special interest groups, who will throw every obstacle they possibly can in the way in the hopes that one of them stops the project, or if not stops it, makes it economically nonviable. For example, in the San Francisco Bay area, the Bay bridge design was changed many times from the original design by Frank Lloyd Writ into some monstrosity with huge cost overruns, and then there was a curve added that wasn't there before which has resulted in hundreds of car accidents.

    I'd actually be surprised if the operators of older plants actively looked for any but the most egregious problems, considering that any repairs they make will end up having to conform to current regulations, and might well result in huge numbers of changes. The resulting hodge-podge of spit an bailing wire would no doubt be significantly more dangerous than just ignoring minor issues until they became too big to ignopre.

    The point is that the cost for her going back to work is rather large, compared to doing the minimum to continue to qualify for unemployment insurance.

    Raising the minimum wage, as the GP to which I was replying suggested would not fix the problem. It's not a problem with the minimum wage, it's a problem with there being an economic disincentive to reenter the job market.

    As to my particular relative, yes, she earned the right to the unemployment, assuming she had an inability to get a replacement job, but the job search being conducted is not a job search to find employment, it's a job search to maintain qualification.

    As to your off-shoring shout, I have two things to say:

    (1) it's a complete non sequitur; she works in a field that it's impossible to off-shore due to the need to maintain scheduled face-to-face contact with other people.

    (2) People are being priced out of the labor market in the U.S. due to free trade agreements with countries which do not have to enforce our environmental or labor relations laws; make tariffs contingent on their complying with our laws in order to do business with us, and the cost of doing business off-shore will go up. Although probably not to the point that the U.A.W. will be able to put humans in jobs better done by robots, as they currently do at companies like G.M. and John Deere, it will be enough to move a lot of manufacturing, textile, and other blue-collar jobs back to the U.S..

  7. Undoing moderation to reply... on Economists: US Poverty On Track To Hit Highest Level Since 1960s · · Score: 1

    I have a relative who makes $1600/month on unemployment; that's $9.23/hour, and if you factor in the income taxes she'd be paying if she were getting that after taxes from a job, she'd need a job that pays $12.47/hour. That's an annual income of $25937.60, which is 232% of what the article claims is poverty level.

    That hourly rate is a break-even number for her, not including the marginal costs of having every day free except the mandated one-day-a-week interview day, which is mostly free considering these are not Google interviews she's going to. You would likely need to pay her significantly more than that to give up her 6 day weekends, since the marginal benefit of actually having to work 40 hours a week instead of interviewing once a week is pretty low in terms of the high opportunity costs.

    Barring an unfortunate incident (like getting hired), she's going to be able to keep miking that cow based on state unemployment insurance plus the federal EUC unemployment extension until January 2013, which is coincidentally about when her COBRA insurance runs out, but hey, then there's the affordable healthcare act in place to catch her. After that, she will likely get a job for a short while, and then go back on unemployment/COBRA as soon as she's eligible, and then eventually she'll be able to do this without having to pay the COBRA (Hey! Pay raise!).

    So would raising the minimum wage to $12.47/hour get her off her ass? No. It wouldn't. How high would it have to be? $12.47/hour plus however much per hour she values her free time. Consider it a discount that she would also not need to add per hour day care costs to that total minimum hourly rate, since she currently does not have children.

    Now multiply her by every unemployed person who is getting government assistance of one kind or another.

    PS: Based on the article, since Federal minimum wage is $7.25/hour (due to go to $9,35 this year, according to the legislation), that's $7.25 * 53 * 40 = $15,080/year, someone making minimum wage is above the individual poverty level of $11,139 by 35%, due to go to $9.35 * 52 * 40 = $19,448, or 75% above poverty level.

    FWIW: If you ask me, this should be the determination of poverty level:

              #define poverty_level ((minimum_wage * hours_per_week * weeks_per_year) - $1)

    which would cut out a lot of the bullshit posturing.

  11. I have a similar brilliant idea! on Gooseberry Launches Android-based Raspberry Pi Rival · · Score: 1

    Let's all build SOCs for SBC hardware for cheap that are capable of 1080p H.254 decode, and then not document the graphics hardware so that no one actually uses them to ship finished machines!

    Maybe at the same time we can all implement the shittiest memory bandwidth we can possibly implement so that we get crappy graphics performance on theoretically good hardware because it's impossible to use a binary blob driver due to the EXPORT_SYMBOL_GPL on the DRM interfaces, so we have to push all the graphics data across the user/kernel protection domain boundary once in full screen mode and 3 times when doing even simple 2D compositing.

    Perhaps we could take a page from some vendors books and run our own hypervisor in the TZones on some ARM SOCs so that no matter how good you make your kernel and driver code, there's no way to guarantee things run in bounded time so you don't drop frames, because you have no way to predict when or why the damn code in the hypervisor will run.

    Maybe we can make things worse by having a lot of crap that should be in the device tree hard-coded in board files instead. Heck, why not just have separate device trees for the boot loader and the kernel so that they can get desynchronized all the time, and if that isn't enough to make things suck, heck, why don't we make the kernel have to have board files too that go out and get values from the device tree which might as well be had-coded to run statically configured drivers, instead of just having the kernel iterate the damned device tree so it's all automatic.

    Perhaps we can also avoid coming up with an ISA, and instead make everything similar enough to be tempting, but dissimilar enough so that it's hard to replace our chip with someone else's chip so we don't have to compete on our ability to deliver superior products (and hope Microsoft doesn't invent one and shove it down our collective throats with Windows 8).

    Yeah, I'm sure the price of the thing is really an issue, like everyone's claiming. Yeah, that's gotta be why there's not wide adoption of ARM. It could not possibly be any other reason.

  17. Technically Apple is probably pushing the line on EU Investigating Microsoft Over IE Bundling Again · · Score: 1

    At least when it comes to the table space, there's the iPad, and then there's the wannabes. This would probably not be an issue, except they disallow other browsers to use their own JavaSCript rendering engine, and instead they have to wrap a UIWebView in their browser. THis has two effects: (1) you don't get high performance JavaScript, and (2) they disable JIT'ing in a wrapped view, so the performance is never comparable to Safaru.

    Admittedly, this comes about from the technical chicken-and-egg problem of JIT'ing an extended UIWebView, vs. not having full support for emerging HTML5 standards (pick one) and Apple's inability to do proxy code signing on scripts like this, necessitating disabling the JIT'ing. They can't trust that the wrapped UIWebView isn't being used to run interpreted programs not explicitly approved by Apple for use on the device.

    But you can argue that this is in fact a wielding of monopolistic power in the tablet space effectively causing harm to browser competitors to Safari.

    I'm also kind of waiting to see if there's going to be a UUNet-style "your filters aren't good enough for me" lawsuit from some irate parent should anything "dirty" get through to their Child's iPod Touch. It'd be logical, given that Apple has elected to content filter the store, and is therefore arguably operating in loco parentis when it comes to protecting kids from the evil applications on the Internet. Should be fun if someone tries to apply the UUNet content filtering decisions to the App Store.

  18. I'm pretty sure he's referring to the ARM systems on EU Investigating Microsoft Over IE Bundling Again · · Score: 1

    Mac OS X != iOS, as much as the Lion releases appear to want you to believe it. The actual bot lockdown on these things was Samsung's, which is why the same buffer overflow attack for the check code worked around it for the initial jail-breaks.

    Technically, there's really nothing preventing you from jail-breaking these devices and running your own OS in place of iOS, other than the alternatives out there so far pretty much suck so there's not a huge incentive for capable hackers to do it. The graphics and I/O stacks on Linux for the Apple hardware are generally pretty low performing compared to Apple's stack, and they're pretty poor performing compared to the Raspberry Pi stack, since they generally try to avoid binary-only drivers in kernel space, and that costs memory bandwidth doing double-crossing of the protection domain boundary. The primary reason anyone does it is to run unapproved applications, which typically includes doing data tethering without paying the phone company for the more expensive fixed-cap tethering plans.

    The problem with the Windows UEFI is that they are trying to put together an ISA for ARM, like in the Intel architecture PC industry, and then lock everyone else out of the hardware. They'd happily do that on Intel, too, if they thought they could get away with it.

    For things like cell phones, where there's incredible regulation on Software Defined Radios, which then varies from country to country, that's really a matter of "you lock your baseband to the particular hardware and vice versa, or you don't get to ship your phone". The iPod Touch and the non-cell enabled iPad are less arguable, as are the putative ARM-based Windows 8 netbooks which in theory won't be unlockable. Well, at least not without using a dediprog to reflash the firmware after opening it up and violating the warranty. That assumes someone with enough clue is willing to spend some quality time with IDA pro and some serious compute cycles to get some matching hashes and/or looking for bugs in the implementation.
