  1. Re:Not looking good! on First Controllable Solar Sail Launched Today · · Score: 2, Informative

    According to this, all of the rocket's stages were powered by storable liquid fuel engines. So it should be immune to the inherent risks of a solid fuel kick motor. An engineer once told me that a certain percentage of kick motors just blow up, despite x-ray inspections and other tests.

    I/O and interrupt handling, like many things, doesn't scale with CPU clock rates.

    Collisions are not a problem on switched networks. Even on older shared media and hub based networks, collisions were not the evil thing that they were portrayed as. Ethernet is not Aloha. See Measured Capacity of an Ethernet: Myths and Reality by David R. Boggs, Jeffrey C. Mogul, Christopher A. Kent. It debunks much of the misinformation that is still prevalent.

  3. Games for the Physically Challenged on Games Are Supposed To Be Fun, Right? · · Score: 1

    I'd like more game designers to recognize that not everyone has the reflexes of hard-core gamer. I often get frustrated by games in which I get blocked at a section that requires exact timing and perfect coordination to succeed. I bought the game to have fun, not to be reminded that I have no future in professional sports.

  4. Re:Will the cell network have preference? on Hybrid Fixed and Mobile Telephony · · Score: 1
    I also live in an overlay area. The first area code expansion was done with a split, subsequent expansions have been overlays. I think the overlay was less disruptive than the split.

    It used to be possible to dial local numbers in three different area codes (DC, MD. VA) with just seven digits. All of the exchanges in the metro DC area were unique. That was before cell phones and pagers exhausted the available phone numbers.

    One of the plans for future expansion of the phone system involves mandatory 10-digit dialing for the entire system, eliminating the use of the leading '1'. After that, there are plans to move to longer area codes and telephone numbers.

    You need to complain to Bellsouth. There were similar problems here with Verizon when 10-digit dialing was introduced. These were quickly fixed. Bellsouth's billing software should be insensitive to whether the subscriber dialed 10 or 11 digits.

    The digit '1' is not a toll indicator in the North American Numbering Plan. Its misinterpretation as a toll indicator is a historical artifact of the way that many telephone switching systems were setup in the relay era. When you dialed '1', your local step-by-step central office handed off the call to a toll switch, which could route and connect long distance calls. In the modern world, it tells the switch to expect another 10 digits. It does not indicate a toll call. A 11-digit number can be a local call and a 7-digit or 10-digit number can be a toll call. Programming all 11 digits into a dialer ensures that the call will be completed, whether it's local or long distance.

  9. Re:Huh? Is this new? on U.S. Offers Glimpse at Manhattan Project Facility · · Score: 1

    What I would like to see is the plutonium extraction and reprocessing plant that was used to extract Pu239 from used reactor fuel rods. When the fuel rods are removed from the reactor, they are thermally hot from decay heat and very radioactive. From what I've read, they built a very large and complex plant that was completely operated by remote control, using 1940s technology. Once it began operation, nobody could enter the plant due to the high radiation levels. All repairs and maintenance had to be done by remote control.

    It's obsolete technology, along with the gas diffusion plant. If someone wants to enrich uranium, there are more efficient methods, like gas centrifuges.

    It isn't just 4500+ tax rates. What is taxable, when it is taxable, and where it is taxable, all vary. Plus borders for taxation do not have to match borders for ZIP codes. I used to live at a place where my post office wasn't in the same state.

  13. Re:Hmm.. on Testing Cheaper Printer Ink · · Score: 1
    Inkjets are good for home use only or in LARGE format photo quality printing. Using then in an office is the absolutely stupidest thing in the world, you can recoup the cost of a $1900.00 Xerox color laser in less than 1 year with ink prices alone.... And yes, I know what I am talking about.

    That's assuming that you have a shared color laser printer or $1900 in the budget to buy one. At many budget-starved agencies, there is little or no money for capital expenditures. It's a lot easier to buy a $100 printer than it is to buy a $1900 printer.

    Another issue is software compatibility. If you are running something other than Windows NT/2000/XP, there may be no printer drivers available for that all-singing, all-dancing, $1900 printer. I bought an Epson ink-jet because it was supported by OS/2.

    According to Francis Cucinotta, NASA's radiation health officer at the Johnson Space Center (source), an astronaut on the Moon would have received a dose of 50 rem, enough to cause radiation sickness.

  17. Re:Would the moon have a 'record' on NASA Notices New, Nasty Solar Storm Type · · Score: 1

    The Moon is more like a dosimeter. You could estimate the total received amount of radiation. The problem is that there is no geological process to create time-ordered layers in the soil. It might be possible to learn something from the proportions of radioactive isotopes in the soil. A really major event could produce a noticeable change in the isotope ratios when compared to those produced by normal background radiation.

    I wouldn't say that it is a matter of efficiency. When you get to the level of NASA Headquarters, politics becomes extremely important. You aren't a practicing scientist or engineer, you are an upper-level manager, concerned about funding and budgets in an environment where everyone is fighting over a limited and shrinking pot of money. Not only that, but you have to defend and sell your programs to the executive branch and Congress. It's not like someone hands you a check and says "Design, launch and operate a spacecraft that does X".
