  1. Re:I'm still waiting on AT&T Claims Internet to Reach Capacity in 2010 · · Score: 1

    The last mile monopoly is of the natural monopoly of running utility lines through public rights of way. There's no law against a cable company applying to a city government to lay cable for a second cable TV franchise, but it's rarely done because it tends to be uneconomic, both the cost side of duplicating work and the revenue side of splitting up the customer base.

    It's more telling that cable and telecom monopolies lobby so hard against city that want to add competition to the last mile, say through municipal wifi.

    Probably a couple reasons. Light weight is less of an advantage on the highway than the city unless the highways are hilly or mountainous. I can't find published drag coefficient numbers, but the Fit is both taller and stubbier than the Civic. Civic probably has advantage in aerodynamics.

    It's just like software bloat. Car models get bigger over time. A new Honda Fit is a closer match to your 92 Civic. It's probably a little smaller outside, but it matches the old Civic for power, comfort and interior room.

    BTW, the EPA adjusted the mileage test for 2008. MPG is down across the board because the old mileage test was unrealistic and didn't match up with real world (read lead-footed) driving.

    http://www.fueleconomy.gov/feg/ratings2008.shtml

    Honda Fit got 38 mpg highway under the old test, 34 mpg highway under the new test. If you drive it like a granny, you'd still get 38 mpg.

    Thanks for the info. It's really tricky passing emissions standards in the pre-catalytic converter days. Until the late 90's, motorcycles with their smaller engines could still pass EPA using the same technology: lean mixtures from a fixed carburetor.

    After that in the early catalytic converter days, high octane unleaded was hard to find which meant low compression ratios which hurt power and efficiency.

  7. Re:OH WOW on Eco-Marathon Team Hits 2,843 mpg · · Score: 1

    For petrol engines, the emissions requirements need a lower temperature burn, which is inefficient. Inefficient, means more petrol.


    That may have been true in the early 70's, but not for any engine built in the last 2 decades. In the early days of pollution controls, you could only find low-octane unleaded gasoline (lead was used as an octane booster but fouls up catalytic converters). This meant low compression ratios resulting in low power and low efficiency.

    These days we have better combustion chambers, high octane unleaded, electronic ignition with knock sensors, and most recently gasoline direct injection. Compression ratios over 10:1 are common. Even the VW/Audi 2.0T turbo engine has a 10.3:1 compression ratio.
  8. Re:No, it's not drug abuse. on Many Scientists Using Performance Enhancing Drugs · · Score: 1

    Good point, and the Libertarians are missing another point. The countries in Western Europe that they so despise as "welfare states" have both universal healthcare AND liberalized drug policies.

    The concept is called harm reduction. It's cheaper to give addicts free drugs and a safe place to shoot up than to have them commit crimes to pay for expensive black market drugs and then have taxpayers pay to run them through the criminal justice system. Yes, they are in effect bribing addicts to leave them alone. I'm sure law-and-order conservatives and libertarians would both find that morally reprehensible, but using the expensive hammer of law enforcement to fix this problem is a high price to pay for your moral satisfaction.

    There's a big difference. Of course psy-ops has a long history going back to WWII, however, it was always directed at foreign media, never at US media.

    In this age of Google News, it's easy for a propaganda story planted in a foreign paper to make its way back to US readers. You can call that psy-ops collateral damage. Targeting psy-ops stories specifically at US citizens is 100% illegal. I'm not talking about press conferences and interviews. Those are still ok, regardless of the truthiness of information dispensed.

    Digital age indeed. I saw this coming with digital cable. Analog cable is a one-way broadcast technology. Although it's possible to build a one-way digital tuner that just grabs the bits off the wire, digital cable boxes are purposely built so the cable company always knows when you watch and which channels you watch. I pointed this out to my family, and they just went, "So what? So the cable company knows which channels I like."

  16. Re:Speak really slowly for me... on Democrats Propose Commission To Investigate Spying · · Score: 1

    You're right about the critical thinking part. It's not like a class you can check off, it's an entire worldview and attitude. Given the research that certain personality traits that influence political views are genetic, I sometimes feel the problem is intractable. In the spectrum of personality types, you'll find people who are rigid in their thinking and see everything in black and white. They defer to authority and feel more comfortable around traditional cultural icons (think the simplicity of John Wayne vs. the complexity of Steve McQueen).

    This attitude is more prevalent on the Right, but it's more correct to call this authoritarian rather than conservative. Libertarians are also part of the American Right, and they mostly don't share this personality trait.

    If you want to talk about the American Left, the urban hipsters who love Obama are the very antithesis of this personality type. The blue collar, Rust Belt Democrats show more signs of authoritarian personalities. If you want to talk about political bosses, I'd say many Democratic politicians aren't liberals at all, but Authoritarians who adopt positions on social issues (say abortion) that appeal to the Left while guaranteeing themselves a place in the political machine.

    7 years ago would put us in the P-III Coppermine era. That's actually fast enough to handle a modern AJAX or Flash webpage, but if you put it side by side with a modern computer it would be severely lacking, even if you loaded the P-III with 2001-era software to go light on RAM usage. We often look back on the past with rose colored glasses.
