  1. Re:TCP/IP Not Right? on Is The Wireless Internet Not Ready For Prime Time? · · Score: 2

    The solution is to use a link layer protocol that improves the reliability of the RF link. There is nothing in TCP/IP that prohibits the use of sophisticated link or network layer protocols to transport IP packets.

  2. Re:Got it here on FCC Considering 10-Digit Dialing [UPDATED] · · Score: 2

    I used to live in an apartment building with one of the old dial entry systems. The telephone company terminated their maintenance support for these systems, they were originally designed and installed by the telephone company, back when the telephone company had a monopoly on telephone hardware. The building management ripped it out and replaced with a box that translated a 4-digit code to a 10-digit phone number, and dialed the number. It had a touch tone decoder to allow the called party to unlock the door.

  3. Re:Complexity: Orders of magnitude larger on Quality Control In Computer Companies · · Score: 2

    From what I've read, Intel dealt with the increasing transistor count and complexity of their chips by investing large amounts of money in design automation software. The early chips were laid out by hand, with lots of mylar. The layout on later chips was mostly automated. Supposedly, the buggy 80286 was a wakeup call for Intel, that the old methods couldn't deal with new designs.

    2. Long distance is anything outside your area code, local is anything in your area code.

    That doesn't work for people who live near the border of the area code. You can live in the Washington, D.C. area and have a local calling area that overlaps five different area codes (DC 202, MD 301 and 240, VA 703 and 571).

    The biggest problem is the mind-blowingly stupid way the US phone companies insist on having cell phone numbers in the same block as the local copper lines!!! Duh, what's the point in this?

    Don't blame the telephone companies. The FCC has prohibited the telephone companies from putting mobile phones and pagers in their own area code, they consider the practice to be anti-competitive. New York is an exception, the FCC grandfathered that area code allocation.

  6. Really Old Bugs on Top Ten Intel Slipups · · Score: 3
    On the 8086, interrupts were not ignored after a new value was loaded into the stack segment register. This required all stack pointer loads to be bracketed with CLI/STI.

    Some early 80386 chips had a defective 32-bit multiplier. Intel weaseled out of it by marking fully functional 80386 chips with a double sigma stamp. Other 80386 chips, with the defective multiplier, were still sold, being "good enough" for users running 16-bit software.

    True flexible segmentation was introduced by the 80286, although in a completely boneheaded way (no switch back to real mode, duh!)

    I wouldn't call it boneheaded. You were supposed to load and initialize the system in real mode, switch to protected mode, and stay there. There was no reason to switch back to real mode. Remember, the architecture was designed long before the world was flooded with crappy PC-DOS/MS-DOS real mode software.

    You are way off base. The problem was alpha particle radiation causing upsets in DRAM memory cells. The primary cause of the problem was trace amounts of Thorium in the ceramic material used for IC packages.

  9. Re:The 80286 on Top Ten Intel Slipups · · Score: 2
    The 80286 had a nice architecture, reminiscent of Multics, it just wasn't what the market wanted. The UNIX market wanted a flat 32-bit address space. The DOS market wanted a really fast 8086. I remember reading an article from one of the 80286 architects, who pointed out that the design effort was started long before IBM and Microsoft came to dominate the PC market with PC-DOS/MS-DOS. The implementation had some problems, operating system writers that wanted to use all of the features of the CPU ran into various bugs.

    I ran UNIX System V on an 80286 for years. It was very reliable. The main problem was porting code written by programmers afficted with "All the worlds a VAX" disease.

    The Defense Department's Space Command keeps track of all the objects orbiting the earth. The early warning system can tell the difference between a missile launch and junk reentering the atmosphere. It is very difficult to bring a satellite down on a specific location.

    I thought this was fixed by CIDR and route aggregation. Plus, many of the backbones will not route to allocations smaller than X, where X may change if their routing tables get too big. This forces people with small allocations to move to a larger, aggregated allocation, or live with the fact that their IP address space is no longer routable.

  21. Re:So where did all the water go? on Mars May Be Dry After All · · Score: 2

    Smaller planets, such as Mars, have less mass and a weaker gravitational field, reducing the escape velocity. This allows gases to escape the planet's atmosphere into outer space. There is a statistical description of the velocity of gas molecules, I've forgotten the name, that allows you to predict the velocities of gas molecules at a given temperature and pressure. If a gas molecule in the upper atmosphere is going fast enough, and in the right direction, it will escape from the planet.

    The electoral college is broken. You can win an election without getting a majority because of it.

    It's not a bug, it's a feature.

    In case people have forgotten, the United States is a union of partially sovereign states, not a homogenuous government. The interests of large and small states must be balanced. That is why we have a Senate, good for small states, and House of Representatives, good for large states. The electoral system gives political power to small states, who would otherwise be ignored in a system based on a direct popular vote. A candidate must do more than appeal to a simple majority, he must appeal to a geographically diverse group of voters.
