  1. Re:Another thing about friction on Pipeline Mass Transit? · · Score: 5, Informative

    If we were discussing ideal friction, you'd be right. However, there's one big problem with that: The real world isn't ideal, and race cars have bigger contact patches than minivans for one very good reason: more friction.

    Finally, friction isn't the only source of energy loss in a rolling tire. In fact, as long as you aren't skidding, almost none of the energy is lost to friction (because rolling friction is really a special case of static friction and energy is lost in dynamic friction). Most of the energy in rolling a tire is lost continuously flexing (and heating) the tire sidewall under the weight of the vehicle.

    Thin steel wheels deform a whole lot less than radials and will therefore lose less energy when rolling.

    But Heinlein had the right idea. Dig the tunnels deeper and have them follow great circles through the crust. Then launch the cabs to orbital velocity (but inside the earth). No wheels. Or expensive magnets. Just a nice vacuum and a very fast ride. Of course, the acceleration/deceleration might be a bit brutal...

  2. Re:"Acclaimed" writer Kevin J. Anderson? on The Legends Of Dune - Volume 1: The Butlerian Jihad · · Score: 1

    But good stories are almost always about interesting people in interesting situations. In stories, we call people, "characters". In order to make them interesting, authors use what is called "character development" to allow the reader to relate to them, understand their decision making, and basically follow along with the story.

    If that makes no sense to you, then I have finally discovered an adult who buys and enjoys Piers Anthony.

  3. So why can't anyone else do this? on India Officially Launches Simputer · · Score: 1

    If the PalmOS sells for $5 to $7 in quantity, why isn't Handspring making money hand over fist on their palmtops at $400+?

    And wasn't the first sub-$300 wince device just announced? Without anything close to these specs...

    So, where can I buy one?

  4. Re:The problem with those reviews... on Two Reviews of Debian 3.0 · · Score: 1

    The only time I rebooted a RedHat system post upgrade was when up2date upgraded the kernel (from a gnome-terminal, there's no need to go to the console to upgrade a RedHat system).

    So, other than a kernel upgrade, what reboot are you talking about? I would expect you to have to logout to upgrade X and the RPM post install script will kick xinitd for an upgrade to the ftp or telnet server... But no reboot needed

  5. Re:Upgading from 7.3 on Red Hat 8.0 Reviewed · · Score: 1

    I have never once had an upgrade run successfully, and I've been using RedHat since 2.2.

    After each and every attempt, I've had to wipe and fully reinstall the whole system. Now, I keep my /home and /usr/local in separate partitions that I back up religiously and they're all that I keep when installing a new linux release.

    It's possible that 7.3 to 8.0 would be the first successful upgrade for me, but I'd rather spend my time doing what I know will work: wipe and install from scratch, bringing over my /home and /usr/local.

  6. Only ten years after I worked on Analog/Digital on Analog & Digital Chips On The Same Silicon · · Score: 1

    When I was a co-op at TI (custom DSP group) in 1992, we had a mixed signal DSP with a c10 core (25% of chip), a 12-bit A-D converter (25% of chip) and a big sea of analog circuitry to combine several functions inside a hard drive into one chip.

    Since then, TI has published a library of cores and analog circuitry (including antennaes, A/D, D/A, etc.) that can be mixed and matched as needed for your custom DSP system.

    This is possibly new and shiny because Intel finally decided to get involved in cell phones. Nothing else about the article is cutting edge or even slightly revolutionary.

  7. Re:Heathens on Virtual Genetic Evolution · · Score: 1
    No, actually you belittle God and make Christians look stupid when you say His Bible is a lie.

    Not all Christians, just the few who insist that the Bible loses all value if it is not a factual account. If the Bible must be factual to have spiritual value, why does the parable of the Good Samaritan have any value? After all, the parable was never presented as being factual, yet was still intended to be a spiritual lesson, a myth if you will.

    The reality is that all of the Bible is as factual as the parable. And much of it has the same amount of spiritual value (lots). But none of that spiritual value hangs or falls just because you believe the the Bible is factual.

    Is it possible that the two creation stories in Genesis are intended to reassure man that he has a place in the universe and those stories are valuable because of the reassurance they give to man as he goes about his daily life?

    The literalist chooses to reach the conclusion that his myths must be true, even when this assumption of factuality deeply weakens the ability of the myths to communicate the critical core of their wisdom. If Jesus is still around and will "set aside" my sins when I believe in him, there's precious little motivation to alter one's behavior. However, if Jesus death and ressurection is an account of how to achieve a joyful life (heaven on earth) by putting aside childish worries and becoming a spiritually mature person, the motivation appears naturally as a part of the learning process.

    As to sin being equal to the knowledge of good and evil, I will agree that some of the myths in the Bible have outgrown their usefulness and need to be read in light of the agendas that early authors and editors had in the formation of the early church. The Sumerian text from which the second Genesis story is taken makes no mention of the arrival of sin, just maturity. Sin and expulsion from Eden was a late addition by the historian who cobbled Genesis together, and was done for reasons now unfathomable. That it happens to fit the guilt-based evangelical tracts of the modern Christian is irrelevant to the real wisdom contained in the Bible, and the Upanishads, and the...

  8. Only accept if ALL of your concerns are managed. on Is it Wrong to Accept an Employment Counter-Offer? · · Score: 1

    First, most people don't quit a job because of pay alone. There are almost always other reasons for the discontent that led you to think of getting another job. If you fail to express all of your misgivings or if the counter offer doesn't actually manage all of your misgivings, it's not a good idea to accept because you simply won't be happy.

    Second, you can ask for more money without letting on that you're looking for a new job, and if you want to avoid hurting your reputation, don't ask for money with a threat (give me the raise or I'll quit). The way to phrase that you're unhappy with your pay is by making a value case (I directly produce value X for this company, and I don't believe that my current pay reflects that contribution. Perhaps we could re-examine my salary?).

    However, if it's entirely about pay, the counter offer does get you the pay you want, and you don't think your reputation has been hurt by the now public job search, go ahead. It's rather unlikely that all of these things are true, but if they are, stay with a good thing and accept the counter offer.
