  1. A little more information please on 2 In 3 Misunderstand Gas Mileage; Here's Why · · Score: 1

    Which one saves more gas:
    a) replace a 10 mpg car with a 20 mpg car.
    b) replace a 33 mpg car with a 50 mpg car.

    From the way the question is posed it is impossible to say. How many miles-per-year does each drive?

  2. Re:Musicians on Research Suggests Brain Has a 2-Task Limit for Multitasking · · Score: 1

    Any jazz organist does this when he carries the bass line for the group. There appears to be a complete separation between the left hand which is carrying the bass and the right which is comping and soloing.

  3. Re:Yup, they block on To Flush Or Not To Flush · · Score: 1

    Where I work all the flushables were replaced by flushless, probably fifty or more. They lasted about a month then the blocking up thing happened. I was in there when the unfortunate facilites worker was attempting to fix it - he was making the Most Distressing Noises working on this thing that I've ever heard. It was not a pretty sound. Afterwards I asked him about it - he said he told management to just try it in one bathroom first but no, they replaced all of them in the plant. Shortly after this they ripped them all out and put the flushable back in.

    I wonder if they sent them back and got a refund?

  5. Suppose I Share An Encrypted File on RIAA Prepares Legal Blitz Against Filesharers · · Score: 1

    And even if such an encrypted file were an RIAA controlled music file, is the RIAA guilty of a DMCA violation by decrypting the file to determine whether its contents are RIAA controlled? Even if the key somehow made it on to the p2p network? What is required, wrt the DMCA, for a file to be declared "encrypted"? Would an encrypted zip file with a password qualify?

  6. Re:Do-it-yourself EMP bomb for the airlines? on Risk Management For Electronics on Aircraft · · Score: 1

    An EMP event would be most catostrophic on those commercial aircraft that use fly-by-wire to connect the cockpit controls with the control surfaces. I think Airbus pioneered certification of this (A320) but not sure if Boeing has one of these yet.

    I prefer hydraulic backups for all control functions.

  8. Re: NEXCOM on Cell Phones and Air Safety · · Score: 1

    What we really need is more bandwidth, and we're getting that by reducing the channel spacing (comm channels have gone from 50kHz to 25kHz, and are moving to 8.33kHz). 8.33kHz spacing provides 2280 discrete channels for voice comm, which ought to be plenty for the forseeable future (i.e. until we go to digital comm using whatever the successor-to-the-successor-of-IP is).

    Actually, the FAA and industry are currently testing the NEXCOM system as a replacement for the current 25 kHz AM voice system, rather than the 8.33 kHz system the europeans are using. Even the Europeans have acknowledged that 8.33 kHz is an interim solution to the spectrum crowding problem. NEXCOM is a TDMA, digital communication system that, depending on the configuration, can provide a user with simultaneous voice and data on one channel. Up to four channels per 25 kHz are supported.

  9. Cell Phone Interference Report on Cell Phones and Air Safety · · Score: 4, Informative

    Here's a report (pdf) that discusses the interference effects of cell phones on aircraft: Interference Levels In Aircraft at Radio Frequencies used by Portable Telephones An html version is available on google.

    Executive Summary

    Measurements made on two types of civil transport aircraft confirm that transmissions made in the cabin from portable telephones can produce interference levels that exceed demonstrated susceptibility levels for aircraft equipment approved against earlier standards. Since aircraft equipment in this class is currently in use, and can be installed, and is known to be installed, in newly built aircraft, current policy restricting the use of portable telephones on aircraft must continue. Recommendations are made to reduce the interference risk and for further studies to understand more precisely the effects of interference to aircraft equipment arising from the use of portable telephones.

  10. Re:ok, but... on Cell Phones and Air Safety · · Score: 2, Informative

    Improvements in shielding have no effect, of course on on-channel interference (antenna conducted), such as would be caused by poor out-of-band emission performance of consumer grade electronic devices.

    With the advent of more composite construction in these new airframes, it is conceivable that they may have less airframe attentuation than the older models, allowing cabin generated EMI to couple via the antenna path.

  11. Re: On-board EMI on Wireless Computing and Airplanes? · · Score: 2, Informative

    An avionics equipment on a certified air transport aircraft must demonstrate (and be certified) that it conforms to RTCA DO-160 emission limits. The equipment must also demonstrate a specified performance level in the presence of defined interference levels. These specifications are designed to prevent interference between on-board aircraft systems.

    With the introduction of the large assortment of passenger electronic equipment that may find its way onto an aircraft, the airframe avionics are operating in an environment that now includes uncertified equipment with unknown radiation performance. As a condition of aircraft certification, only certified avionics are allowed on-board, and I understand an airline's discomfort in allowing the passengers' non-certified equipment to be operating on the airframe.

  14. What? No tubes? on HP Unveils Its Digital Media Receiver · · Score: 1

    I'm not putting this next to my Audio Research SP6 until I see the glow. Okay, so maybe I will - there are those that won't though.

    The presence of tubes and audio freek specifications will be an indication that these things have truly arrived.

  15. Make it run straight on Pinewood Derby Tips? · · Score: 1

    The car straddles a wood strip as it drops down the track. If it has a tendency to turn it will repeatedly turn into the strip as it drops, generating much friction as the inside of the wheel rubs the strip. Insure that it runs true.

    Regarding friction on the wheels, the head of the nail (you may be required to use them) will contact the wheel as will the wood on the inside of the wheel. You may want to address these areas, tapering the nail head and inside to minimize contact area.

  16. The ElectriClerk on Typewriter Keyboard Conversion · · Score: 1

    and then kill it?

    Okay, so there was the matter of some crufty, probably 80's era networking code - but I digress.

    $GOD the hours I spent playing that game. My memories of the 30-man squad nights flying from Ghost and capturing Solo and beyond are nothing but good. There hasn't been an online flight sim since with the community and fun element. For those not familiar with the game, or how long it had been around before EA squished it, some sense of the community and the angst felt by the AW neophyte can be had by reading the series of postings by scavenger to the old AW mailing list. Someone please buy this thing from EA and resurrect it.

    I go diving down.
  20. The Harrow... on Palm OS Powered Tattooing Robot Debuts in Vienna · · Score: 5, Informative

    '...appears to do its work with uniform regularity. As it quivers, its points pierce the skin of the body which is itself quivering from the vibration of the Bed. So that the actual progress of the sentence can be watched, the Harrow is made of glass. Getting the needles fixed in the glass was a technical problem, but after many experiments we overcame the difficulty. No trouble was too great for us to take, you see. And now anyone can look through the glass and watch the inscription taking form on the body. Wouldn't you care to come a little nearer and have a look at the needles?'

    The explorer got up slowly, walked across, and bent over the Harrow. 'You see,' said the officer, 'there are two kinds of needles arranged in multiple patterns. Each long needle has a short one beside it. The long needle does the writing, and the short needle sprays a jet of water to wash away the blood and keep the inscription clear. Blood and water together are then conducted here through small runnels into this main runnel and down a waste pipe into the pit.'

    > Downloading a page and preventing the ads from displaying is stealing.

    When I view a web page I seldom read every page or wait for every image to load. I presume you don't think that it is incumbent upon me to view every page of the editorial (non-commercial) content of a web site, and that I am allowed to pick and choose among this content. If so, why must I differentiate between the editorial content and the non-editorial (ads) portions?

    I consider the ads just one more piece of content, to be viewed or discarded as is my prerogative.
