  1. Police Dash-Cam 2.0 on Riding Shotgun With the Google Street View Beetle · · Score: 2, Insightful

    Imagine future versions (with much lower prices) of the "Dodeca 2360" camera used as Police Dash-Cams (but on top of the car).
    With the increased Law-Enforcement use of WiFi/Wireless-Data access and the necessitation of Computer capabilities in modern Police Vehicles, this device would make a nice streaming Police roof-cam.
    (The quality looks good enough that "Cops" or other 'reality' police shows might just fund the costs for the cameras too.)

  2. Will it will have FCC Approval? on Stopping Cars With Microwave Radiation · · Score: 1, Insightful

    I know that many "FCC Approved" electronic devices in the US have the following (US) FCC Notice labeled on them:
    "This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and
    (2) this device must accept any interference received, including interference that may cause undesired operation." http://www.fcc.gov/oet/ea/labels.html

    I Do Not think the FCC had in mind 10,000 Watt RF pulses for the "must accept any interference" clause.
    I consider this a device with high problematic potential for numerous electrical devices at distances farther away than 15m. HAM Radio Operators in the US are limited to emissions of up to 1.5 kilowatts PEP (and 2.25 kilowatts PEP in Canada) of Electromagnetic Radiation on specific frequency ranges.
    It is hard to fully imagine the interference that a device that emits 10,000 Watt pulses of Microwaves could do...
    Imagine if it went off near a Datacenter... Imagine if it went off near a Hospital ICU or ER?
    For that matter it could be used in the hands of "terrorists" to disrupt all sorts of sensitive electronic devices...
    I can not imagine that this device would be something which US Government would allow to be be used in-country by any of its civilian law-enforcement agencies.

    NOTE: MICROWAVE Radiation is NOT in the "100 hertz" range. It is in the 300 MHz to 300 GHz range. http://en.wikipedia.org/wiki/Microwave
    The "100 hertz" frequency falls into the Bass hearing range of Sound Waves, NOT Microwaves...
    Besides, 10,000W at 100 hertz is close enough to the 12-14 hertz "brown sound" that may actually be more effective stopping drivers of suspect vehicles... http://othermag.org/brownnoise.php

    Great, Now "terrorists" are going to attempt to wire a series of 10 (easily obtained) 1,000 Watt 2450MHz microwave oven Magnetrons (powered by a 10 kilowatt inverter/capacitor/generator) on top their cars to pulse unsuspecting targets... -Z http://en.wikipedia.org/wiki/Microwave_oven

  7. Writing Time for 1TB via USB? on Researchers Achieve Amazing Memory Density · · Score: 1

    How long would it take to fill a 1TB "Thumb Drive" over USB2? or even USB3?
    Some Numbers...
    1TB = 1024^4 = 1,099,511,627,776 bytes http://en.wikipedia.org/wiki/Terabyte
    USB 2.0 Transfer Rate = 480 Mbit/s http://en.wikipedia.org/wiki/USB2#USB_2.0
    USB 3.0 Transfer Rate = 4.8 Gbit/s http://en.wikipedia.org/wiki/USB2#USB_3.0
    1 megabit = 10^6 = 1,000,000 bits which is equal to 125,000 bytes or 125 kilobytes. http://en.wikipedia.org/wiki/Mbit
    1 gigabit = 10^9 = 1,000,000,000 bits (which is equal to 125 decimal megabytes or 119.2 mebibytes, as 8 bits equals one byte) http://en.wikipedia.org/wiki/Gbit
    Some Math...
    Time required to transfer 1TB over USB 2.0 @ (480 Mbit/s) is: (1,099,511,627,776 / (480*125,000)) = 18325.19 Seconds = 305.42 Minutes = 5.09 Hours
    Time required to transfer 1TB over USB 3.0 @ (4.8 Gbit/s) is: (1,099,511,627,776 / (4.8*125,000,000)) = 1832.52 Seconds = 30.54 Minutes = 0.51 Hours
    So,
    Even if the USB 3.0 specification meets its proposed data transfer goal, 1 Terabyte would take about 1/2 Hour to transfer.
    -I hope USB3 is around the corner SOON, because 5 HOURS over USB2 is a bit too long to wait while transferring 1TB onto a USB2 Thumb Drive!

  11. SPIN Translation = Synthetic Fuel from COAL !!! on The Development of Ecologically Sound Jet Fuel · · Score: 4, Informative

    Jet turbine power plants have have 2 SIGNIFICANT advantages:
    (1)They can operate with just about any type of chemically and thermally stable combustible fluid with a sufficient energy density having consistent and reliable combustion properties.
    and
    (2) They are not hampered by the well-known significant inefficiencies introduced by exhaust emissions systems such as mufflers, catalytic converters, EGR systems, etc..

    NOTE: Modern Jet fuels are hydrocarbon BLENDS. http://en.wikipedia.org/wiki/Jet_fuel
    These blends are created as cheaply as possible to meet specific fuel properties and standards, including their energy content, and intended use: http://www.csgnetwork.com/jetfuel.html
    There have been many well-intentioned pushes for "replacement" Jet fuels, including a "safer" version which was intended to reduce fire balls when Jets crashed, but it was a flop as it introduced safety concerns as the 'safety' additive increased the possibility of a flame-out (it basically made the flash point of the fuel higher and reduced the flammability of jet fuel mist) and it cost way too much for little if any margin of safety it would have introduced. (Most people in jet crashes do not die from a fireball of jet fuel, but from actually hitting the mountain, crashing into the ground/ocean, or basically some form of 'Aortic Dissection' http://en.wikipedia.org/wiki/Aortic_dissection )

    I say that this is really a SPIN and a PR campaign.

    Everyone looks good waving the environmental flag, but when compared to boats, trains, and trucking, jets are NEVER environmentally friendly. (Jets have to fight gravity continuously when moving goods and people = INEFFICIENT)
    TFA ( http://www.princeton.edu/main/news/archive/S18/96/92S56/index.xml ) is a Press Release about research into processing "Biomass" into Jet fuel And, oh ya BYW, COAL!! THAT'S RIGHT, COAL!
    We are talking about fuel from "other than" OIL Sources = SYNTHETIC FUEL (AKA SynFuel), specifically SYNTHETIC "JET" FUEL. http://www.syntroleum.com/pr_individualpressrelease.aspx?NewsID=907157

    This really has EVERYTHING to do with the price of oil being SKY HIGH (pun intended): http://www.peak-oil-news.info/new-synthetic-jet-fuel/
    Everyone knows that Aviation drinks fuel of any kind faster than other transportation types (when you realize the efficiency ratio of Distance traveled with quantity of cargo compared to actual fuel used per unit cargo (person, metric ton, etc..) for that given distance)
    We are talking about stirring up money to get more research into the conversion of Coal into Synthetic Jet fuel (and other fuels) and we'll get to work with biomass too.
    Oil is so expensive these days it is becoming just as cheap to chemically engineer/create (from scratch!) synthetic Jet Fuels from Coal. (which the US still has hundreds of years worth)
    Why expensively pump it out of the deep ocean, or the middle east, and then transport around the planet (BYW, they use ships for this because of their efficiency, not jet aircraft) when you can just dig up some local Coal or Bitumen Tar Sand deposit http://en.wikipedia.org/wiki/Tar_sands and make your own synthetic fuel.
    (Now observe the pollutants released and the energy required during the "upgrading" of Coal/Bitumen into the new Synthetic Jet Fuel http://en.wikipedia.org/wiki/Upgrader )
    FYI: The Germans made Synthetic Jet Fuel during WWII because they had Coal but not so much oil...

    Researchers have been doing this stuff for over a decade. And there are REAL Intellectual Property issues here.
    Genetically Engineered DNA sequences in many cases can be treated just like programming code.

    I remember a true story from one of my Genetics Professors, Dr. Ron Van Den Bussche ( http://cas.okstate.edu/index.php?option=content&task=view&id=27&Itemid=71 )
    He told our class about a genetically altered cotton strain of which he was integral in its development.
    Apparently, a giant agri-industrial competitor to the giant agri-industrial company who funded the strain of cotton Dr. VDB developed,
    surreptitiously obtained a reproduceable/cloneable live specimen and subsequently cloned it and used it in gross quantities for their own unlicensed use.
    (I think the new strain could tolerate saltier soils and drier conditions and it grew a larger puffier bowl of cotton, oh yes, and it was Patented/Copyrighted also.)
    -->Here's the really funny part, Dr. VDB and his team were expert witnesses in the intellectual property infringement lawsuit/trail against the competitor who allegedly stole the strain. (sorry, can't remember what state)
    The defendants had claimed they developed the new genetic strain of cotton themselves.
    This was proven blatantly false by the prosecution when Dr. VDB revealed he had spliced unique identification DNA sequences into their genetically-engineered cotton strains from a VERY Very Rare Bat species.
    (which happened to be an endangered species that ONLY inhabits a single remote cave system in Texas).
    Sure enough, forensic DNA testing was completed on the allegedly stolen cotton strain and it was, in fact, found to be stolen.
    -Many, many, Million$ of dollars were paid by the defendant to the plaintiff.

    In your example to the good post from calebt3, in the case of certain virus infections, or other malware which infects the windows restore feature, you would likely need to disable 'system restore' it to effectively clean/scan your system

    You might want to obtain your specific system's Original Dell Windows XP OEM Installation disks.
    You can get them from Dell here: https://support.dell.com/support/topics/global.aspx/support/dellcare/en/backupcd_form
    If Dell is out of your specific system's original OEM reinstallation disk set, it is probably just the pre-loaded drivers and crapware specific disk they are out of.
    Most Dell's (that ship with a Microsoft OS) have an OEM Microsoft sticker on the bottom/back with the 25-digit activation key. (you may/may not need this if you format and reinstall from scratch)
    If the Dell OEM version of Windows XP (Original, SP1, SP2, etc..) from the sticker is determined and Dell is out of your CD, ask friends, family, some local Dell computer repair shop, etc.. to "use" one of their disks. (you are not supposed to 'copy' the Dell OEM disks). The fancy 25-digit key sticker on the bottom of your Dell laptop is your Microsoft OEM License ("what you pay for" as far as your purchase of OEM WinXP) and the CD from Dell just happens to be the packaging so there is usually one CD/DVD per system version (SP1, SP2, etc..) of OS and when installing it will check for the correct DELL BIOS signatures (whatever they are).
    If they are out of your specific disk, you could look on eBay for an identically named disk if the above fails. (Dell typically makes the version different OEM Windows disks different colors for each version)
    You would need to download the proper OS/Hardware drivers form Dell here: http://support.dell.com/support/downloads/index.aspx?c=us&l=en&s=gen
    NOTE: Some Dell PCs shipped only with a hidden HD partition where the OEM Windows files were kept. (You may want to check if Dell has OEM disks for you, and if not then do your research before using any other sourced DELL OEM OS disk).
    Of course, you could always use something like Norton Ghost to make a backup image of your HDD to a removable drive or CD/DVD once things were "perfect" and revert back to that image if your system gets hosed. (but you literally would be at that point and lose all changes to OS and data since that image)

    The Air/Water fluid interface where one observes common "waves" are observed as water waves because the air is transparent (but it too has waves).
    The difference here, is that we have two air masses of different temperatures and humidities (thus having differing densities) interfacing as fluids AND one of them happens to be an air mass that contains visible moisture in the form of clouds.
    It is likely that this type of air/air fluid "wave action" happens frequently at the interface between differing atmospheric air masses (AKA fronts), but in this example the clouds made it easily visible.

    I had an 89' Nissan Pathfinder and it had factory wiring harness connectors to ALL of the various electrical connections which were water-tight with one or more ribbed red silicone gaskets.
    The connectors were not always easy to disconnect, however, after 177,000 miles and 11 years of original ownership, I never found any corrosion inside any one of them I ever disconnected for service.
    Additionally, the male/female electrical contacts within the sealed connectors appeared to be made from a tinned Copper and/or Brass metal. This is important to note, as Brass, and to a much larger extent, Copper, have ELECTRICALLY CONDUCTIVE oxide states (as surface corrosion by moisture and/or other aqueous solvents).
    In other words, you corrode a Copper or Brass metal electrical connector, and it will still conduct electricity just fine. It may degrade certain frequencies of network/data signaling and alter the dB loss and impedance, but it will still conduct.
    This is another reason why the top-post Nissan main battery terminal connectors for this vehicle were made from a Copper/Brass strap instead of a traditional Lead connector.
    Lead oxide powders (as found on many old standard Lead top-post automotive battery terminals) are not effective electrical conductors (as anyone who has wiggled/cleaned a corroded connection to allow their car to start could attest).
