    You have to remember that a test measures several levels of knowledge by having a range of easy to hard questions. A properly performed test on a random population should result in a normal distribution around a defined average. That average is solely based on the test so it has no bearing on the actual intelligence of the population. The test is more sorting the population then comparing it to a standard.

    Actually, no: it should result in a normal distribution around an average, not a defined average. The range of the resulting distribution is then compared to a standard. In this case, the range failed to overlap the standard boundary, and so everyone flunked out.

    If you futz with the standard based on the observed average every year, then you are effectively cheating the people in better performing years by causing the higher education to contain remedial elements that the higher performing students already know, and you move the sliding window of the top end of what can be learned at the institution downward.

    This is effectively the same reason there are admissions tests in Japan as well, although in Japan, the majority pass, so it ends up being a numbers cut-off at the top end of the range instead, for the number of available slots.

    If everyone in Liberia who took the tests had passed to the acceptance standard, they'd have to institute a similar numbers based cut-off to that of Japan, since there would not have been sufficient slots for all potential students.

    It's much worse in countries where you have to pay to get an education, which means that there are young people who can't afford going to university (or college) even though they might be better suited for it than their dumb but rich neighbours,

    Being rich doesn't mean you pass and get your degree, even if you can afford to be there. Beauty is skin deep; stupid goes to the bone.

    Egalitarianism is a great social philosophy in theory, but it fails pretty quickly in the face of inequality of ability. You can guarantee equality of opportunity, and most modern societies try to do this - this is why there are scholarchips and BEOGs (Basic Educational Opportunity Grants), but there is no way, given inequality of ability, to guarantee equality of outcome.

    >

    So it seems my guess was correct and you're all bellyaching about a program taking advantage of an unstable API, with a feature not guaranteed to be there, and when the documentation recommends not distributing production apps yet.

    I checked out the SDK link you provided. The iOS and Android sender examples were last updated July 30th. The breakage occurred post-July 30th, so the documentation should have been updated with working examples, or the references to using the SDK to create 3rd party senders should have been removed.

    As I was in the Chrome OS group at Google, and not the Google TV group that is responsible for ChromeCast, I have no idea how frequently that group updates their developer documentation. However, if it's anything like the Chrome OS group, other than design documents, the documentation tends to stay rather out of date for Chrome OS, since there are no technical writers specifically tasked with updating documentation.

    So it could be a bug or an intentional API change (for which the documentation is now out of date) that caused the breakage. However, since the breakage has been pretty localized as to where it occurred, it's unlikely to be supported via an alternate API, which implies intentionality, since releases are tested internally before going out to production systems.

    Frankly I am surprised in this case. Being able to stream content is a selling point with broad appeal, unlike say Other OS on the PS3 which was only used by a tiny fraction of PS3 owners.

    Good argument, except it's unlikely they are making money on the hardware, so the goal is not to sell Chromecast devices, the goal is to allow people to buy Chromecast devices at cost in order to be able to sell content, and to sell content in order to sell advertising. For a bare-bones devices, it's unlikely that additional economies of scale are going to increase their profit margin on the hardware any, and it may in fact be a loss-leader, like the PS/2 or original XBox.

    Am I the only one wondering how water in California can be threatened by fire?

    It's easier to push water than to pull it. So the pumping stations which are needed to push the water up hill are located at the bottom of the hill, and there is infrastructure in place along the rim (it's a rim fire) to supply power to those facilities. It's the same reason that electric power is currently at risk by the fire.

    According to this article, it's worth recycling, although if you dye it green or other colors, it goes down in value, but is still worth it from an economic perspective: http://en.wikipedia.org/wiki/PET_bottle_recycling

    We should probably just go back to glass bottles for most of he stuff we ship around in PET containers; for fruit and berriers, we should go back to raw cardboard, which was typically made from recycled paper anyway.

    To address the larger issue, we should make sorting a lot easier by picking on or two classes of plastic which are easily distinguishable from one another, and only make plastic items out of those few plastics. If we could do away with paper labels, using container-printed labels instead, that'd also help.

For most crypoprotectants used in the process of vitrification, you are limited to one cell type one which it has best effect. The CI folks mostly try their best to preserve the brain without freezing damage, at the expense of some of the other cell types. This has been successfully used on laboratory animal organ transplants for mammalian livers, kidneys, and hearts; the first reference is a patent on the method of prepping the organ, which the second is a PubMed article case study dealing with a rabbit kidney vitrification and subsequent live transplant.
