    In Germany (and probably other European countries) in some college degrees you attend lectures for a couple of years and then have an oral or written exam covering several semesters of work.

    I should not have been so glib in my response. I do know that there are courses and courses of study where the only thing that counts is the final. There are also a number of professions in the US, such as medicine and law, where there is a final pass or fail exam which you must pass as your final hurdle to receive your license to practice.

    The fact that there are such courses does not blunt my question. What do you think when a teacher tells you the ONLY thing that matters in the entire course of study is your score on a single exam to be administered after the course is complete?

    What I think I am trying to say above is that the approach of using only a single standardized score to measure student achievement is not academically sound. There are a lot of reasons for this, but one good reason is that standardized tests are typically paper and pencil tests.

    Would you allow a surgeon to operate on you who got a perfect score on a paper and pencil test about brain surgery, but who never actually performed any surgery before?

    That's an extreme example, but it illustrates one of the fundamental problems with standardized testing. There are others. Over-emphasis on standardized testing would be very dangerous to society.

    The FCC decided a long time ago that the answer is no - in fact, their rules say once 85% DTV penetration is reached, the analog broadcasts in any given area get switched off.

    Not exactly correct. First of all, the FCC didn't decide this, it was the Congress. Second, the law states that all analog broadcasts will end on Dec 31, 2006.

    The 85% DTV rule is a loophole in the legislation which states that if 85% DTV penetration has not been achieved by 12/31/06 then the date may be pushed back.

    OTOH, if the 12% is a lower class demographic, they probably have less disposable income and thus are not the people television advertisers are trying to reach.

    I have no data to back this up, but I would be willing to bet that the 12% is not so much low income as low interest in television.

    For low income families, cable t.v. is one of the cheapest forms of entertainment available. A buck or two a day for hours of entertainment. (I believe the average American watches about 4 hours /day)

    Some people, believe it or not, do not watch tv. My tv has only been plugged into the antenna 3 days out of the last 4 years. (election day, and first two days of Iraq invasion)

    It's possible, from a strictly business point of view, that this could be a good move for broadcasters all around.

    As others commenters have stated, the broadcasters have no choice in this matter. The US gov't is going to pull the plug on analog broadcasts and auction off the spectrum. As of now, I believe this is set to occur at the end of 2006. The date will likely get pushed back, but it is definitely going to happen.

    I don't expect back-of-the-envelope calculations, such as you posted, to be 100% correct, but your example implies that quick 'fueling' for electric cars is infeasible because it would be necessary to deliver 8000+ amps to the vehicle.

    I don't know how authoritative or accurate this information is, but this site says electric motors are in the neighborhood of 80% efficient, with gasoline in the neighborhood of 40% efficient.

    So even if you could somehow create a fully electric car with the same weight and driving range as a gasoline car, your calculations are incorrect because the 60% of the energy stored in the 20 gallons of gas you base your calculations on is lost in the conversion to mechanical energy by the motor.

    I think your assumption that the batteries in a Prius carry the same energy as a 20 gal tank of gas is incorrect. The big limiting factor of electric cars is the power density of the battery. That is, pound for pound, gasoline stores far more energy than a pound of battery.

    That's why the car has both a gas motor and an electric motor. The electric system provides the torque for acceleration, while the small gas motor provides keeps it going down the road.

    Your calculations should be based on the batteries , not gasoline.

    And even bittorrent could handle the job, with a few modifications to the current code.

    You could probably enforce shared uploading in the old p2p systems, also.

    The difference between the "old" p2p systems and bittorrent is one of emphasis. P2p emphasizes availability of many files. Bittorrent uses very similar technology to emphasize enormous bandwidth capability.

    Peercasting is the next logical step. It's not the opposite of P2P sharing or torrent-ing. It's the next evolutionary step, but one that could revolutionize the dissemination of high bandwidth content on the internet.

    Remember what it was like way back two years ago, when your favorite distro released a new version, there was a period of days or weeks where you could not hope to get a decent download speed from the mirrors? Not anymore! Thanks to bittorrent, the more people grabbing the file, the faster the download. More importantly, the costs of providing that content has gone to essentially zero, because the costs are shared by thousands or millions of users instead of being borne by the peope providing the content or mirrors.

    And even bittorrent could handle the job, with a few modifications to the current code. Though, with every node trying to grab pieces of the file in linear sucession, bittorrent's not as effecient at sharing the load.

    With that said, would you care to name some advantage of peercashing now?


    Uh, the same as before. Ordinary P2P cannot handle massive and sudden increases in demand for a file. Ordinary bittorrent will not stream content. Peer-casting will do both.

    To oversimplify it a little: bittorent + streaming = Peercasting

    Or: Streaming P2P + swarming bandwidth = Peercasting

    No, but only a very very few are going to command the sort of salaries that they used to make when there were only few studios/networks/labels.

The big studios and labels will have to compete with little guys who work for next to nothing and have next to zero costs. Kinda like Linx vs. Windows.

    Peercasting technologies change what will be produced, who will produce it, and the amount of money that the final product will be able to get in the market.

    The challenge for content producers will becomme more than ever, to find an audience, rather than to find a network/studio/label/publisher who is willing to take a chance on your work.

    Peercasting technology just allows someone to broadcast content more cheaply, which means for some reason you want to force people to watch certain videos at certain times

    Not true. Streaming from a library of existing files allows for true Video on Demand (Note that is the subject of my original post), where a user chooses from a menu of available content and they can begin watching immediately. With peer to peer filesharing, you have to wait for the entire file to download before you can open the file. With peer-casting, you can begin to view the stream almost immediately, like ifilm.com.

    The difference is, if I post a very popular file I don't have to worry about bandwidth, servers, etc.

    Think what this does to the business models of internet content providers who currently finance huge server farms and bandwidth bills with advertising. For them their costs go close to zero, which is good, but it also removes the barrier to entry in the market. You and I have just as much access to provide video on demand or live webcasts to the internet as msnbc.com or ifilm.com.

    That way, if you start downloading a very large video file, say, and find out after a couple minutes it's crappy, you can move on to something else.

    You have to already have your own channel setup, and millions of users at least previewing it at the time... If not, nobody is going to know there is something worth watching on that channel, at that exact time.
