  1. Synchronous vs. Asynchoronous on ARM Offers First Clockless Processor Core · · Score: 4, Informative

    Most digital logic has at least one repeating signal called a clock, which is used to sequence the logical changes (e.g. from 1 to 0) in the circuit. By limiting changes of state to a periodic time, you can simplify a digital design. One of the major challenges in digital design (besides errors in logic) is dealing with timing related issues such as race conditions. Race conditions occur when a logical operation uses the results of earlier operations. Because of the finite speed of signals inside a chip, sometimes a signal arrives too late for a proper operation to occur. Such an error considered to be a race condition.

    Clocks help by allowing the designer to effectively freeze the state of the logical circuit on a regular basis. This way, all the signals in a chip can propagate to where they are supposed to go, then the logical operations occur. This process repeats on every clock pulse.

    The problems with using clocks are pretty significant, however. First, you need to add a lot of additional circuitry to implement a clock. Another problem is that generally, A LOT of changes happen on every clock tick, which means a large spike in electical current (because you need to use the electrical current to actually change the state of all of the digital circuits). This spike also causes what is known as noise in electronics, and with higher frequency circuits, the noise can actually cause interference with other unconnected electronics (this is known as EMI). And another problem with a clock is that you generally need to keep it running all of the time for it to be useful, which means using electrical power even when no changes are occurring.

    So, the asynchronous CPU is a significant engineering feat. It is very difficult to design, but it is probably much smaller and more efficient than any equivalent clocked ARM core. That said, I wonder how do you actually evaluate the performance? With synchronous CPUs, it is a simply a function of the clock speed and architecture. In addition, all of these devices need to be tested so that they are guaranteed to work - I wonder how they do that.

  3. Re:Better Together? on Treo 700w Review · · Score: 1

    I have a Treo 600 (I'm old school), and the only reason that I don't use it as my regular MP3 player is because they don't have a standard size headphone adapter. Other than that, it is great - good sound fidelity (based of course on the quality of the MP3 file), and excellent battery life (more than 15 hours of playing time). The adapter that I have is too big, and the headphones that directly fit the input are too crappy.

    Needless to say, the Treo is an excellent PDA, and it works fine as a phone. Some of the integration features are really neat. For example, you can look up a business with Google, then touch the phone number that Google conviently supplies, and the Treo will ask if you want to dial that number. Geek Heaven!

    Everyone is talking about designing and fabing the chips. However, you also need to test them once they are fabbed. That is another big effort - you will need to generate the test vectors, then design an interface board, plus a whole lot of work. And the cost is also significant - it could easily cost $10000 for a loadboard. In fact, high end sockets for testing easily top $3000. Add $100/hour of equipment costs, and you start to get the idea .For the big semi houses, testing the manufactured chips costs more than the actual manufacturing.

    Well, ok, we are closing on on the fundamental disagreements.

    My assertion is that the loopholes exist at least in part due to corporate influence on the legislative process. While the entire process may be completely legal:
    1) influence legislature to pass favorable laws
    2) reap benefits of new law
    3) repeat

    It does not mean it is 'right', nor fair, nor is what the majority of people want. But you really don't care about that. And economic growth is not the be-all and end-all of our civilization. At the very least, such matters as military defense, scientific exploration, and legal rights all matter. I at least expect you were upset about Supreme Court decision on Eminient Domain in New London, CT? That decision furthers economic growth.

    I disagree with your assertion on taxation of corporations. In the past, corporate taxes were a much larger percentage of the Federal Budget, yet corporate growth was still solid. I also think that a fair level of taxes (which I pay a solid amount of, BTW) is fine. Does that mean I wish to pay more taxes than I do now? No - I want people to pay their fair share. When I see MS performing such tricks, I think it is BS, since such stunts are not available to everyone, only the large corporations.

    But, I expect we are at an impass - I doubt that you will be swayed by any further arguements from me, and I'm sure that you are in the complementary position. But now we both know what the axioms are of this discussion.

    Microsoft enjoyed more than $12 billion in total tax breaks over the past five years. In fact, Microsoft actually paid no tax at all in 1999, despite $12.3 billion in reported U.S. profits.

    General Electric, America's most profitable corporation, reported $50.8 billion in U.S. profits over the past five years, but paid only 11.5 percent of that in federal income taxes. That low tax rate reflected almost $12 billion in corporate tax welfare for GE.

    IBM reported $5.7 billion in U.S. profits in 2000, but paid only 3.4 percent of that in federal income taxes. In 1997, IBM reported $3.1 billion in U.S. profits, and instead of paying taxes, got an outright tax rebate. Over the past five years, IBM enjoyed a total of $4.7 billion in corporate tax welfare.

    In the US, corporate taxes (state + federal) are about 40%! 40%!
    Maybe you meant 4%, not 40%?

    even more...
    If big corporations actually paid 35 percent of their U.S. profits in federal income taxes, as the tax code ostensibly requires, corporate income taxes this year would total at least $308 billion. But actual corporate-tax payments this year are expected to be only $136 billion. In other words, this year (and next), for the first time since the early 1980S, corporate-tax loopholes will actually cost the U.S. Treasury more than the amount companies pay in income taxes.

When was the last time that a political representative asked all (or even a modest percentage) of his constituants on a particular issue? If you think the DMCA was proposed and pushed by the grassroots, you are sorely mistaken. How about the criminalization of copyright violations? Or the copyright extensions? I just chose this area because it is easiest to highlight the discrepency between citizen interests and corporate interests. There are many other areas of interest, such as taxation.

    Just in case you are among those who don't know what a corporation is (shamelessly ripped from nasd.com)...

    Corporation: A legal entity, allowed by legislation, which permits a group of people, as shareholders (for-profit companies) or members (non-profit companies), to create an organization, which can then focus on pursuing set objectives, and empowered with legal rights which are usually only reserved for individuals, such as to sue and be sued, own property, hire employees or loan and borrow money. Also known as a "company." The primary advantage of for-profit corporations is that it provides its shareholders with a right to participate in the profits (by dividends) without any personal liability because the company absorbs the entire liability of the organization.

    Next, take a look where all of the corporations are based - try Bermuda, which provides wonderful tax advantages. Look at how many companies are opening up facilities in Ireland, also for tax advantages.

    Quite simply, corporations do not have much concerns about the people. Honestly, I am fine with that- corporations exist to make money. However, the large corporations are powerful enough to tilt the political and legal systems in their favor, to a level that is significantly greater than any average person - that is something that I don't think is fair.

    I think that it should be illegal for corporation to lobby or influence the government in any way whatsoever. Why is that fair? From your own statement All public corporations in the US are owned by citizens. If a shareholder cares enough about an issue that affects a corporation he owns part of, then he can directly lobby the appropriate governmental agency on that matter.

    I think that you could make a barbell-shaped tow. One end has most of the mass, and attached to it with a tether a few hundred feet long is the actual ion drive/whatever. That way you don't need to angle the thrust as much. Place the massive part very near the asteroid, and the ion drive pulls from 5 hundred feet away.

    But, according to my calculations (assuming an asteroid mass of ~1e18kg), a 20ton rocket would take 20years or so to pull the asteroid 1/2 of the earth's radius. Let me try that again - I get ~1month/(meter away from the center of mass of the asteroid). So, if you could get 1m away from the center of mass, then it would take 1 month. But, since you can't get that close, lets pick 200meters (which is still very agressive, since the asteroid is 1000meters on its major axis). 200months-> ~17years.

    A newbie can typically last longer than 30 secs in other multiplayer FPS games like Counterstrike, so I think the spawn campers are an especially vicious problem in Battlefield.
