  1. Re:I think it's good on Free Tuition for Math, Science, and Engineering? · · Score: 1

    You bring up an interesting point, which I've never seen appropriately discussed.

    In some of our special ed classes, there were what were called "co-teachers". In our specific implementation, there was essentially one teacher and one behavior specialist, who were also both trained in the other's discipline.

    I've never seen this approach used in classes like biology, chemistry, or physics, classes that are hands on, lab oriented, and require special attention from the teacher.

    Why not use two "teachers", one specialist in the subject, who also has teaching credentials, and one teacher who also has science credentials.

    Well, that could be ideal, as the feild specialist would be the best person to answer questions etc, while the teacher is the best person to relate the material to the students. However, It is currently very difficult to keep the teacher with science credentials in teaching, due to poor salary and working conditions. It would strain the budgets of most schools well beyond the breaking point to have classes with 2 teachers, not to mention the problem with trying to retain them both.
  2. Re:Backwards on FCC Puts 4.6 Billion Minimum Bid on Spectrum Auction · · Score: 4, Insightful

    If goggle buys this, I can be almost certain that it will be used to create a nationwide Wireless network, probably a "broadband" network.
    The problem with the current systems are that only the existing cell companies can get into the business. There is no real way for a competitor to enter the market. Further, in general only approved devices can be used on the network (although the GSM networks are the exception). The companies can dictate what the network can be used for. As a result, Cellular internet prices are outrageous, and unfair.

    So what Google would do is but the spectrum. They would standardize on a protocol. They would let companies provide services (most likely internet services) on that band. The companies offering services on that band would be required to let any devices that support the protocol to be used (likely a SIM-card like system would be used). The companies could not restrict the applications or services used on the network. Smaller companies would have a much better chance to get in on the action, as the major requirements would be an antenna on a cell tower, and a large internet connection. They would only need to provide the end users with a SIM, as the modems could be gotten anywhere. The total overhead of providing 700 MHz internet access would be far less than the traditional cell system, and thus there would be significant competition, and low prices.

    The key here is that the spectrum owner has no interest in providing the service themselves, and has no reason to sell out to the large companies. So they would have no problem allowing multiple companies to provide the service in the same area. That is not heard of for most utilities. Also, unlike cell phones, the companies competing in the local area would not conspire to fix prices, as the cost of entrance would be low enough that a new player could easily join in.

    If I am correct about that, that would be the sort of thing the government should do. That sort of regulation would level the playing field, and thus allow capitalism to work well both for businesses and for consumers. That would be the sort of regulation that is ideal. Unfortunately all too often, government regulation works to make the playing field less even, in the favor of the entrenched large companies that are already working in that sector.

    While you are right be careful about confusing dynamic range compression (i.e. making the difference between the loudest and softest noise smaller by increasing the volume of the softest sounds) and audio format compression. I'm sure you are well ware of the difference, but Some of these people are not. Some people are quating bitrates without naimg the algorithm! Bitrates of different encoding algorithms are nor comparable. Then people tend to forget that the sampling rate (or it's analouge equivalent: (Tape quality)/(tape speed), (record quality)/(record speed), etc. ) has lossy compression-like effects (namely loss of information compaired to the original sounds). [Admittedly, sampling rate issues are mimial compared to the others, but one cannot deny its existence].

    One thing I find odd is that few consumer audio devices seem to allow for intentional dynamic range compression (very useful for overcoming a noise floor, or for fixing movies that have enormous dynamic range, (theater style), where if you don't have the television turned up high enough you cannot hear the conversations, but if you have it high enough, the music or certain sound effects can be almost too loud.

But if a particle was in the overlapped area, how could it leave one event horizon to end up in one of the black holes after they have separated?

    • Debian has a policy of not introducing new upstream versions into a stable release. Instead, any necessary security changes are backported. MoCo's policies tend to counter this. But this was not too major an issue, and could likely have been resolved.
    • Debian distributed Firefox with some patches. MoCo's policy is that patched browsers cannot be labeled "Mozilla Firefox" or "Firefox" without special approval. Debian policy is that any such permission must not be Debian specific nor can it excessively delay the release of security fixes.. It seems likely that there wold be negotiations, and eventually a reasonable compromise could have occurred.
    • However there was the deal killer: The Firefox logo. The Firefox logo's copyright license does not meet the DFSG. Debian has a very stict policy there. It is not a problem that the logo is a Trademark, and thus special licensing conditions. The problem is that the MoCo was not willing to consider placing the logo copyright under a free license, and simply place restrictions on the image as a trademark. Debian therefore was unwilling to distribute the logo. Debian was willing to use a replacement logo that had been manually recreated, and looked nearly identical to the original. Obviously the use of that recreation would be subject the any trademark restrictions of MoCo. However, MoCo's policy was that only the official logo could be used, not a nearly identical replacement; the logo's copyright license was not going to be changed; and that the "Firefox" name cannot be used on a browser without the Logo. MoCo was not willing to compromise on these issues at all. So the choice for Debian was allow the official logo in despite its failure to meet the DFSG, have a renamed version of Firefox, or have no Firefox at all.
    As you can see, that last issue was an absolute killer. It was not even worth working to resolve the other two unless that one was fixed. MoCo was not willing to compromise at all on the last issue. Debian decided not to compromise on the DFSG issue. So now we have Debian Iceweasel and Icedove.

In most cases, many smaller companies competing is better for the people and economy than one or two large companies. As far as fiscal issues go, The government should ideally be required to maintain a balanced budget.

    There must be some government regulation. The Government must be able to bring anti-trust suits. Otherwise you get monopolies like the old Standard Oil monopoly. (Ma Bell is not a great example because of other government regulations.) You need right-of-way laws (Some industries definitely require this, most notably the Electrical industries). Safety regulations should stay too, as the market is all too likely to choose cheap but highly dangerous products over slightly more expensive but far safer products.

    For industries where for practical reasons there needs to be some regulation, I see no problem with that. I would see nothing wrong with a government department owning all the telephone lines, and allowing any company to use them for a fee, where the fees are calculated as to cover the costs of maintaining the lines/installing new lines as needed, but without generating a profit. The idea is that the company that owns the lines does not have an unfair advantage (Which is the current situation). (The laws do not let a cometing company put up a competing set of lines, as having 2 or more compete networks of phone lines in an area is absurd and not practical).

    The key to capitalism truly working is always to have many small companies competing as equals. So the law should generally work to minimize one company having an advantage over another.
