  1. Design on NASA Mars Rover Spirit May Move Forward By Spinning Its Wheels · · Score: 0, Flamebait

    This should be a lesson on how not to design a Rover. Getting out of a sand trap isn't hard if you think about it beforehand and plan accordingly. We knew Mars was sandy before we sent them there. Some sort of jacking mechanism that moves the wheels out of the holes they're in, or wheels on articulated arms that can be moved one at a time out of holes. Even bigger wheels would have made getting trapped in the first place less likely.

    The first thing I do with source code with lots of white space is :g/^$/d. This occasionally lets me put what was once a 200 line file onto the screen all at once. If the code is well structured, the structure becomes evident; with many blank lines loops and blocks are hidden because they can't be seen all at once.

    It's so important to see everything at once that I often print out files and tape the pages together. Then I use colored pencils to show blocks and flow.

    If the group insists on double spacing, I can always run it through a sed script when I'm done.

    It makes no sense that your mother has DSL and her neighbors are limited by line filters to dialup at 14.4k due to lack of capacity. If the capacity is there for DSL, then it's plenty for 56k dialup.

    Installing filters on lines for the purpose of limiting dialup modem speeds makes no sense; it's unnecessary expense when the modems themselves could be set to limit data rate (if capacity were truly the problem.)

    It's possible that there are loading coil(s) on the lines. It's an old trick to extend the usable length of voice lines, but it has the side effect of limiting bandwidth. Limiting bandwidth is not the purpose of loading coils.

    The farms that produce large quantities of food are not "log cabin" operations. They can afford satellite links. Many farmers don't live on their farm, but in a moderate-sized town within 20 miles or so of the farm. Remember that the big farming areas in the U.S. are the midwest and California's inland valleys, FLAT land where line-of-sight microwave links could be set up if they were so inclined.

    Look at the Tektronix website, www.tek.com. Their products are expensive, and in my opinion all modern oscilloscopes are unjustifiably expensive. Modern semiconductor technology should make a 4 channel 100 MHz digital sampling oscilloscope available for under $1000 -- far under $1000. Somebody lacks vision or isn't trying hard enough.

    Polaroid had one trick, instant-print film and cameras. As far as I can tell, it was never really very strong financially, stumbling to make the next advancement in its technology to rescue it from impending doom. Quality never met conventional processing, and additional copies meant weeks of delay. Cheap 1-hour processing weakened its market substantially, and digital cameras sealed its fate. I don't think any management could have saved Polaroid. Look at Kodak, which had a huge industrial base to work from and has heavily and desperately invested in digital technology: it is struggling to remain a viable corporation.

    Many intelligent people use their intelligence not to find the truth, but to find better arguments to uphold their beliefs (right or wrong).

    Second, it's well established that people can be very good at compartmentalizing their knowledge. That critical faculty you worked so hard to hone for solving engineering problems goes right out the window when your preacher is lulling you to sleep. Similarly, you can become quite adept at ignoring the evidence that's staring you in the face. (My last day at MIT, an udergraduate in the physics department told me at length how wonderful Christianity is and tried to lead me into a prayer session. All the time I had prominently displayed a lapel pin that showed my support of Objectivism.)

    Cherished beliefs come first, and it's the unusual person who will overcome them.

  10. Re:Thomas Jefferson != murder on Why Do So Many Terrorists Have Engineering Degrees · · Score: 1

    If you are a chattal slave, you don't "consent" to anything. Your consent is irrelevant and meaningless and therefore nonexistant.

    There were bad masters and (relatively) good masters. The better ones were wise enough to know that happy people produce better than unhappy people, and forcing people to do things they really didn't want to would not make them happy. Of course, ultimately, a slave who wished to live had no power to not consent; but at the margin there was some consent involved.

    The claim that Thomas Jefferson raped his slaves is new to me; I am aware of no historical record that makes this claim likely. There is no DNA evidence that points to Jefferson that does not equally well point to others in his family. In particular, I've heard (from Michael Medved) that Thomas Jefferson had a cousin with a bad reputation. That person was around the TJ household at the time relevant to a possible Negro-Jefferson ancestry. I am not a person who is impressed with Jefferson's moral qualities, but your claim (that he raped his slaves) is an unjustified outrage.

    The problem is that Islam, like Christianity, is a peaceful religion

    The Bible is chock full of violence and the Koran is much worse. It takes a very selective reading of either to come to the conclusion that either is peaceful. Just one of the problems with both books is that they are incoherent, self-contradictory messes from which any sort of conclusion can be derived.

    I've read more lies about Ayn Rand than about any other person. You add to the total.

    Atlas Shrugged was published in 1957; the copyright should still be intact. She married O'Connor in 1929, not late in life as your statement weakly implies.

    With regard to the Buckleys, Rand thought they were terrible and criticized them very heavily. She urged the defeat of James Buckley.

  17. Re:Lady, there ain't nothin' so complicated... on A Brief History of Modems · · Score: 1

    DSL over POTS lines is limited by the fact that high frequencies attenuate over distance. The higher the frequency, the shorter the distance. When the loss reaches about 40 dB, the signal has to be regenerated. The result is that for distances beyond a mile or two, repeaters are required for DSL over copper above 1 Mbit/sec. If you want to go faster when you're at the limit, you have to add more repeaters. This can go on almost indefinitely, but eventually other technologies (fiber) become more economical than trying to shove electrons down a twisted pair.

    Suppression requires either secrecy or a patent system. The patent system is time-limited, therefor can't suppress forever; furthermore the patent system involves government, which has a dubious relation to any "real free market." Also, there are countries that don't honor the US patent system, so development of a sufficiently advantageous technology could take place outside the US.

    Suppression by secrecy can happen under any political/economic system, so the relation to a "real free market" is moot.
