  1. Re:Especially considering dirty bomb on Medical Radioactive Material Truck Stolen In Mexico · · Score: 1

    Journalist keep touting the dirty bomb concept, but even with a big blast you would not propel enough Co 60 to kill people in a wide radius.

    It wouldn't require a big blast. In Thailand in 2000, a similar source of Cobalt-60 that was removed from it's protective container by scrappers resulting in 1900 people being significantly exposed, 10 requiring hospitalization, and 3 deaths. And that was just from a canister sitting there. Take that same amount, but atomize it in an explosion in a populated area and suddenly you have a lot of people inhaling it, spread around and contaminating a decent sized area requiring a massive cleanup effort.

    Even a small dirty bomb can be more devastating then a large conventional explosion without radioactive material. The conventional explosion's damage happens all at once...once the explosion is done and the dust settles, the damage is more or less done. With a dirty bomb, the damage may continue on and not be realized for years down the road with health issues.

    This also doesn't even consider the public reaction to a "dirty bomb" going off. People volunteered to help when the WTC fell and ultimately the clean up and reconstruction efforts became a tourist attraction of sorts. I don't think that you'd find that happening with a dirty bomb site as soon as it happened after 9/11.

  2. Document your correspondences to your boss when you notify vital security issues. Make sure your e-mails are not only backed-up, but you get read receipts or something showing your boss opened the e-mail (and might have read it). Keep those receipts archived. When poop hits the fan, at least, you are protected.

    I'd print them out. That way when you stand in the unemployment line, you'd have something to burn to keep you warm on cold winter's days

    A print out may document it, but if the shit really does hit the fan, documentation may not cover your ass much.

    Indeed, I'm going to speculate that the main advantage, on average, of electrically-operated air conditioning in a modified car is the ability to locate the compressor (and all associated plumbing) wherever it is most convenient, instead of it needing to be at the front of the engine.

    It also allows for more flexible options for powering the compressor. An electric motor allows the compressor to operate at a smooth speed that can be varied based on demand, rather that all on or all off of a conventional AC clutch system. Or if your AC system is marginal on a very hot day, needing to rev the engine while stuck in traffic to cool the air blowing out the vent.

    Most hybrid vehicles these days I believe have some type of an all-electric or hybrid-electric compressor. Toyotas just powers their compressors with high voltage, where Hondas used a hybrid approach with dual scrolls that can run off the ICE for the primary cooling capacity, but can switch to electric when the engine is stopped, or both at peak demands.

    I never said that or anything close to that. Let me break it down a little more for you.

    With a normal belt-driven compressor, the pulley is always spinning, regardless if the clutch is engaged or not. Even when disengaged, this adds a small amount of drag to the engine.

    If the vehicle has an electric motor for the compressor, the motor can be electrically disconnected either by a switch or just unplugging it. If an electrical motor is not turned on, it is not going to cause additional drag on the alternator. The alternator will have drag as it too has friction, moment of inertia, etc, as well as the resistance that occurs through generating electricity for normal vehicle operation. But the AC motor isn't a factor when it's switched off.

    If the AC compressor motor is switched on, then yes, of course the alternator would have additional drag.

  6. Re:When you have a bad driver ... on Is the Porsche Carrera GT Too Dangerous? · · Score: 1

    It does when you can electrically disable the compressor guaranteeing there will be no additional drag due to AC system. With a belt-driven compressor, there is additional drag even with the AC clutch disengaged. The electric compressor still has the drag of the alternator, but that drag is going to be there regardless as an alternator is required for normal car operation in most cases.

    IMO the "millions of separate tax districts" died with software

    Well I'm glad that was settled 30+ years ago when PC use skyrocketed in businesses of all sizes. Or if you want to be more forgiving, the last decade and a half after the Internet explosion of the mid to later 90s. Except its even more of an issue now then what it was 15 or 30+ years ago.

    Just because you have "software" don't magically solve the issues. There's 11,000+ tax jurisdictions in the US and many of them don't line up to geographical/governmental/political boundaries such as just a zip code to quickly and easily identify which rate may apply. Add in multiple different categories of goods, how the goods may be use (commercial, personal, medical, etc), exempt, partial exemption, and progressive tax rates, use tax vs sales tax, are services and/or shipping taxable...it's a nightmare.

    Yeah software can make that easier so you aren't looking everything up by hand. But whatever sales software that you use has to make use of whatever data source you have setup for your type(s) of goods. Plus your data must be continually kept up to date which either requires significant effort on dedicated employee(s), or subscribing to some type of a service that hopefully tracks everything correctly.

    All this also doesn't even take into account the filing of the sales tax that hopefully you didn't screw up (but probably did at least in some small way). Maybe it's not a huge deal for Amazon to handle for their direct sales. But what about small mom and pop businesses that just use Amazon for the storefront but now are considered as having a nexus in all states? Or if they have their own storefront that is subject to internet sales/use tax collection?

    They have no idea what the speed limit is at any given moment. The data recorders aren't recording GPS information. They are recording telemetric data about HOW you operate your vehicle.

    For instance, they can detect how quickly you accelerate to a particular maximum speed, how quickly you start breaking an come to a complete stop. With an accelerometer, they can tell how fast you are driving when turning, did you brake and how much you did brake before that turn, etc.

    It's comparing your driving habits to that of hundreds or thousands of other drivers. There's always going to be stray data points. But if they see you going from a near standstill to 70MPH with wide open throttle, or the reverse of 70MPH to 0 over a very short distance very frequently, then that can be a sign aggressive driving.

    Almost everyone drives a mix of highway and city driving. So while in your case you may accelerate and decelerate firmly coming on and off a highway, do you do the same with city driving? Or do you anticipate the timing of the lights so that you can keep a constant steady pace hitting green lights? Are you constantly changing lanes abruptly and/or speeding up/slowing down? Or do you see the guy turning on to the road and change lanes gradually while maintaining your speed?

    It's no differently then an actuary looking at your medical history, do you smoke, what are your lifestyle choices, etc when deciding on your life insurance policy. Supposedly with the car insurance they aren't moving the "unsafe" drivers into a more expensive rate, they are moving the lower risk "safer" drivers into a cheaper one. That being said, I don't believe for a second that rates won't go up. The safe drivers will just end up paying what they are paying now, and the unsafe drivers will pay more. But that's going to happen whether you or I participate in the data recording or not.

The left wishes the website would have worked. But with close to 2 months left before anyone is required to have insurance, there's still time.

    Look at previous administrations for more embarrassing things. Bush with his wars in Iraq and Afghanistan, lies about WMD, and everything that resulted in the "War on Terrorism". That's an embarrassment. With Clinton, the affair with Monica Lewinsky and all that came with that was an embarrassment.
