  1. Re:Urban Myth! on Can Cell Phones Ignite Gasoline Vapors? · · Score: 1

    Actually, I think it will.

    Once it fills up, even if your hand is holding down the trigger, you'll feel the bang of the 'tap' turning off inside the pump. The trigger can stay all the way down (now with less pressure) but gas is no longer pumping unless you release it and re-press the trigger.

  2. Re:Urban Myth! on Can Cell Phones Ignite Gasoline Vapors? · · Score: 2, Informative

    A cell phone generally gets signals from up to 20 nearby cells before deciding on which one to register on. I don't think that's the issue.

    I would think the issue has more to do with the doppler effect. Cell phones were not designed to run at relative speeds in excess of 100mph, as the frequency shift starts to add up and may cause interference with other frequencies (I doubt it would go into the airline control systems as a result of doppler).

    It is also possible that cell phones do interfere with some onboard control things.. Have you ever put a working digital cell phone next to a pair of speakers, a monitor, etc? Hear the buzz? (I haven't researched what that is, but I think its an artifact of TDMA encoding - also used in GSM phones. If my theory is right, it should buzz with a CDMA phone [if you have a CDMA phone, and you can get things to 'buzz' like GSM/TDMA phones, please let me know so I can think of a new theory])In any case, I'm sure they can sheild for that sort of thing.

    Some airlines are implementing onboard picocells so that passengers can connect to the airplane's own cell phone 'network' and avoid problems due to doppler effect.

    BTW, out of curiosity, has anyone used their cell phone on a plane before (connecting to the land-based cells)?

    Since Slashdot, to my knowledge, is completely in English. I would guess that 99% of people reading these comments will NOT NEED the 4th CD. (However, some may want it if they speak other languages as well)

  5. Sorry, I think this article is BS on Cry To Beat Iris Scanners · · Score: 1

    Sorry.. I have to say that this article is BS (or they are using some pretty old technology)

    Modern Iris recognition systems are completely unobtrusive. They use two video cameras, one for detecting the person, and another for zooming in on the eye. No lasers or infrared are needed, just video cameras without a flash.

  6. Re:Notice how the date is in April? on Videogame Character Threatens National Security? · · Score: 1

    Next time, I'm not going to wear any t-shirts with non-english writing on it.

    I actually got searched twice at that airport (in Orlando, FL); this was in Aug 2002, so I wasn't too surprised to get searched; I just thought it was hillarious that a large security officer of 'colour' stopped me to ask me where is South Park.

  7. Re:Spam him back on Stopping Overseas Fax Spam? · · Score: 1

    The problem with these links is that we don't know if there are 30 "Flamingo Travel" places in the world. The best thing to do would be to call the phone # 800-328-9795, and ask them if they have a web site, and that you'd like more info.

    I once had a security officer in an Airport stop to ask me "Where is South Park" (I was wearing a South Park T-shirt with writing in Hebrew & English), trying not to laugh, I responded that its a TV show. He then proceeded to ask me to take off my shoes and checked me for explosives.

  10. Re:Portable face detector on The Face Detector · · Score: 1

    I don't think this is anything new. I have an IEEE paper here of a group that did a similar system in 2001. There are systems that do face recognition and verification; but nothing with high accuracy (people have been working on this for years using many methods, the main problem is that you need to be facing the camera perfectly straight). Iris and retina recognition, on the other hand, can be done with a relatively high accuracy.

  11. Re:The guys doing flyovers for wifi hotspots. on In-Flight Wi-Fi Makes its Debut · · Score: 1

    Actually, I was thinking.. People could turn on Internet Connection Sharing, or NAT or whatever equivalent after purchasing their connection and resell it to others on the flight for cost recovery.

  12. Re:WTF??? on Build A Stereo From an Old Hard Disk · · Score: 1
    Apparently not.. It also seems to make people confuse a 'Stereo' with a single mono speaker (see quote from article):
    Audio jacks can be stereo or mono, three segments on the connector denotes a stereo jack and two a mono, by now we're going to build only one speaker box, so if your jack is stereo join right and left wires together.

    What that web site doesn't tell you is that most license plate recognition systems do not require special lighting in daylight hours. If its visible to the naked eye, it can be visible to cameras.

    Yes, "under stormy skies" is a perfectly valid location; just as valid as saying, "I'll wait for you by the car," where "the car" is a location in "the midwest."

    I hate to get into a technical grammar discussion, but other than a couple of missing commas, that sentence does seem to be grammatically correct.

    "Unfortunately, my current location in the midwest, under stormy skies, puts me in a bit of a disposition."

  22. It was actually launched last week on NASA Gravity Probe Launched · · Score: 4, Funny

    What most people don't know is that it was actually launched last week.

    Its experiments of relativity caused it to move close to the speed of light forcing the effects of time dilation to make it appear as if it was delayed 24 hours, when in reality it was launched long before its scheduled date.

  23. Of course its delayed, its moving very fast! on 'Einstein Probe' Delayed · · Score: 1

    Of course its delayed, if you know anything about relativity, you would know that as things move closer to the speed of light, it has an more significant effect on relative time.

    Its moving very fast, and actually ahead of schedule acording to atomic clocks on board; however, according to the time that we perceive it is delayed by 24 hours.
