  1. Re:Actually, that's Wrong Too on On Electricity (Generation) · · Score: 2, Informative

    You're right about higher octane fuel being more resistant to knock and pre-ignition. As far as tuning for fuel octane, the only things that the engine computer can adjust are spark timing, fuel mixture and the maximum boost in a supercharged engine. The most important parameter, compression ratio, is fixed in the physical structure of the engine.

    A high compression engine can take advantage of higher octane fuel, but it doesn't care if the octane boost comes from ethanol or some or ingredient. The important parameter when tuning for ethanol blends is fuel mixture because alcohol already contains oxygen (in effect, it's a little "pre-burned").

  2. Re:No thanks on The Privacy Candidate · · Score: 1

    I think you nailed it. She has a long history of playing it safe in her Senate votes, from the Patriot Act to the Iraq War authorization, all with an eye to her future presidential campaign. She was one of the biggest war hawks on the Democratic side, maybe second only to Lieberman, and she was one of the last Democrats to turn against the war, now that public opinion is solidly against it and it's completely safe to be anti-war.

    But about video games and flag burning, it goes beyond playing it safe. She actively led the charge to protect us from video games and flag burning (oh please, save us!). It's like she wants to act tough on the war and act tough on a few social issues, but hit the other issues just left enough to win over Democratic voters. To cut through all the confusion on issues, just remember this. Hillary Clinton's the Big Money candidate. She can't shill for Corporate America as blatantly as Republicans, but she knows who pays the bills for her campaign. I'm a Democrat, and I'll be doing all I can to nominate someone else. I really hope it's someone else.

    Remember how SACD and DVD Audio were hyped up a few years ago? I guess people cared more about the convenience of iPods able to hold their whole music collection than the quality of hi-def audio.

  4. Re:Not so cheapo on Small Form Factor PCs · · Score: 1

    It's cheap for a SFF computer. The closest equivalent on the PC side is an Aopen Mini PC which runs just under $300 for barebones with no RAM, disk or CPU. A Shuttle XPC is cheaper, but much larger. A MicroATX system is even cheaper but larger still. There's really 2 classes of devices covered by this book. Full powered computers for HTPCs and embedded systems for routers. A Mac Mini doesn't work as an embedded system but does work as a mini PC. Except for MicroATX, most SFF PC parts are pretty expensive, and you don't save a whole lot over a Mac Mini by building it yourself.

  5. It's your body's set point on Does Sprawl Make Us Fat? · · Score: 1

    There's a lot of evidence that people's body weights have a set point where they will settle no matter how much they eat. Diet and exercise can keep someone's weight below their set point, but it's a constant struggle. You can't blame it all on lack of willpower or laziness because there's a biological component to it too. I exercise regularly, and I'm in pretty good shape, but when I've slacked off in the past I didn't instantly balloon up. My body weight just went to its set point, ranging from average in college to slightly overweight in my 30's.

    Where you can blame sprawl is that junk food and lack of exercise allow more people to reach their set points.

    Actually, the gas that makes flatulence stink is hydrogen sulfide. There's not enough to hurt you in the average fart, but it's still pretty poisonous, and it can build up to dangerous levels in the manure pits from animal farms. Methane itself, CH4, is odorless.

  7. Re:Gmail on Yahoo Mail Forcing Ads Through Adblock? · · Score: 1

    Um, no. When you delete a file on your hard drive it deallocates the sectors so when there's more write activity those files eventually get overwritten, or you can deliberately overwrite free space. After a few overwrites, recovery of the data becomes non-trivial. When Gmail deletes a message it goes into a giant Trash folder that's never deleted and never overwritten.

    Well, to him, sitting on your ass collecting dividends from your trust fund is being economically productive because that money is being made available for companies to invest in the economy. I just love how the country club Republicans square that logic with the old Protestant work ethic.

  9. Re:Hmm. on Detection of Earth-like Civilizations in Space Now Possible · · Score: 1

    The real longshot is that artificial, high power radio transmissions have only existed on Earth for 70 years, and who knows for how much longer? Compare that to the 5000 years of civilization, 200,000 years of modern humans, and the 5 billion years that the solar system has existed.

  10. Re:HD on Flash Memory HDD for Notebooks Launched · · Score: 1

    The transfer rate on most flash memory is slower than hard drives (sometimes much slower). Their only speed advantage is no seek time for random access.

  11. Re:What are you on? on Why Do We Use x86 CPUs? · · Score: 1
    But Intel had a lot of money, and the companies behind many of these chips started shaking in their little silicon socks. What's the point of continuing to develop a MIPS workstation processor (CPU development is very expensive) when Intel are going to the roundly thrash them in the marketplace within 2 years?

    If you compare Intel's engineering budget to everyone else's, it was clear the smaller players could not compete on CPUs at the level of investment required. Intel had a good architecture in the P6 core, and they threw a lot of money at die shrinks and incremental improvements. The economies of scale of selling to both desktop and server markets meant low prices and big engineering budgets.
  12. Re:Brilliant! on Wal-Mart Is Pushing Compact Fluorescent Bulbs · · Score: 1

    Same here. Edison subsidizes the CFLs so you can buy them for $.50 each. Even with no subsidy, Ikea sells them for around $2 each. Cost is not an issue. I can't remember the models or brands right now, but the performance of new ones is a huge improvement over early ones. The first one I ever bought was about 8-10W. It was dim as all hell and needed a second or two to start up.

    By tasty animals, I'm guessing you're talking about the various varieties of bland, factory-farmed livestock. There's just a small problem with that called biodiversity. When you have a monoculture of a certain crop or livestock, all it takes is one plague to wipe them out all around the world.

    Modern winter tires do that already. The top layer of the tire has microscopic pores to wick away the water from the ice. It wears quickly on pavement though, so this construction is only used in dedicated winter tires.

    Well, to fill in the missing bit, living in crowded, dirty conditions builds up people's immunity to disease. The important one here is cowpox, a close relative of smallpox. Cowpox is pretty harmless to humans, but catching it gives you an immunity to smallpox.

  20. No guarantee on Are Background Checks Necessary For IT Workers? · · Score: 5, Insightful

    "a 2006 study showed that 30% of insiders who are caught launching an attack against their employers have arrest records, and that those charges don't generally include computer crimes."

    That means a background check won't catch 70% of the malicious insiders. This article is meaningless without info about the rates of attacks from insiders who would've passed or failed background checks. It's a reasonable hypothesis to say that IT workers with criminal records are more likely to launch insider attacks, but there's no scientific evidence of it in this article. It's all fluff based on one person's case.

    It also was also a much less competitive market back then. The Atari 2600 had no competition in 1979. When the NES came out, the video game market had crashed after the early 80's boom. When the Playstation came out, there was no 3D competition. The late 90's was the most competitive era out of those three systems, but either way the ante up to get in the game was much lower. You certainly didn't have two entrenched competititors like when the Microsoft broke into the market.
