  1. Robot lawnmower on Robotic Butler available for $800 · · Score: 2

    Actually the robot lawnmower has been around for about 20 years. The electronics have gotten better and cheaper, of course. This robot butler has spiked wheels for running on the carpet. I wonder how well it will work on grass.

    • Roll up in a ball the same size as the soccer ball and bump the real ball around. Do you suppose the opposing team might get a little confused? Might the opposing team acquire a few fouls for kicking opposing team members?
  3. How on Ask Slashdot: IP Masquerading Drawbacks? · · Score: 2
    How, indeed. We can't make other programmers do anything.

    As programmers we can improve competitors' products who are following standards. As customers we can avoid proprietary products, just as we did with MicroChannel. As reviewers we can mention if products use proprietary methods or standards.

    The AOL and MS messaging customers and tech support are getting lessons in that right now.

  4. Standards on Ask Slashdot: IP Masquerading Drawbacks? · · Score: 2

    Simple. Make the game writers follow, or create, a standard. They keep creating proprietary data formats which only their software understands. Then customers find that firewalls and competitors (ie, the current AOL and MS squabble) are not compatible.

    Hardware

    • Teletype ASR-33, teletypewriter very popular as a computer terminal.
    • Popular Electronics, January 1975, cover story: MITS Altair 8800 microcomputer.
    • Apple II with its color graphics and multiple easy-to-access expansion slots.
    • IBM PC and its corporate desktop success providing cheap hardware for all.
    • IBM's MicroChannel bus and its failure showed the popularity of open hardware.
    • Hayes modem command set allowed modem control without custom device driver.
    • VGA graphics. Finally the IBM PC could show reasonable images. Web browsing later became a significant side effect.

    Software

    • VisiCalc. Killer App. Welcome to "electronic spreadsheets." A reason to buy a computer.

    Early Computer Magazines

    • People's Computer Company, an organization promoting personal and community computing. A computer newspaper before there were computer publications. Community Memory was an early idea for sharing computer databases at computing storefronts.
    • dr. dobb's journal of Computer Calisthenics & Orthodontia, an early proponent of publishing source code. Evolved into Dr. Dobb's Journal.
    • Byte magazine, its huge 50,000 copy beginning and eventually the first computer magazine to appear on general magazine racks.
    • Kilobaud magazine, very popular hacker magazine, often with sources (remember programs on vinyl sheets for playback from phonograph player into cassette interfaces?).

    Conceptual

    • Homebrew Computer Club. Build your own computer if you can't afford a small CDC or PDP to heat your house. I was designing a TTL personal computer until the 8080 appeared; sure was nice to have quad NAND DIPs.
    • Xerox PARC center with its influential network and user interface experiments.
    • MECC: Minnesota Educational Computing Consortium" spread timeshare computing to all Minnesota school districts, then Apple computers. I worked there in the 1970's. State of MN has since sold it.

    Just build a Network Interface using an old 486. Maybe Linux in the Network Interface, but that's not important as it's just a network device. Do the real networking in that device. Connect the NT boxes to the nearest Network Interface.

  15. Re:"time is a two-way street" on New Heavy Ion Collider could "destroy the earth" · · Score: 2
    Actually, when our Moon was torn out of the Earth a lot of the upper crust and primitive atmosphere were ripped away. The result is our thin atmosphere and relatively thin crust.

    With our full share of atmosphere we'd have a much higher pressure and greater greenhouse effect. We also would have much more silicon and fewer metals available at the surface. Plate tectonics might also not be operating, so our present cycling of carbon and water back to the surface might not be happening. The Earth's core might also not be rotating and generating magnetism the way it is.

    Our planet would be more like Venus. But it is not because the Moon is there but rather how the Moon appeared there.

    There was a letter to the editor in a recent Scientific American about that possibility. The reply explained why it was unlikely and pointed out that more powerful cosmic ray reactions happen frequently in our own atmosphere. If it could happen, it would have happened billions of years ago.

    "much of the US defense would be decimated by EMPs from the first attack wave"

    • The U.S. has no defense against missiles.
    • U.S. misiles are designed to withstand EMP because they'll be exposed to it from the first explosions in a group ("fratricide")
    • Missile silos are protected against EMP at various levels.
    • EMP can destroy tube based devices also. You've never run too much power through a tube, have you?.

  23. Re:sr-71 on NASA's X-37 · · Score: 1
    I put my son in the cockpit of the Blackbird at the museum next to Minneapolis-St. Paul airport last Sunday. The museum volunteer next to the aircraft said several thousand SAMs have been fired at these aircraft. Only one SAM hit, and the aircraft landed at its base with part of the missile stuck through a wing (obviously not an entire SAM, as that's like a telephone pole and a Blackbird is not a large aircraft).

    I wonder how powerful a SAM explosion is when compared to the forces of the airflow over one of these birds.
