  1. Re:I have a non-apple charger for my MacBook... on After a User Dies, Apple Warns Against Counterfeit Chargers · · Score: 1

    I have a real one, and it does the same thing. In fact all of them I have had (including the old flying saucer style from the TiBook era) do that. It's the inrush current, not a defect.

         

  2. Re:Not buying it on After a User Dies, Apple Warns Against Counterfeit Chargers · · Score: 1

    A fake one could be made any number of ways that could be potentially dangerous, If it's made with an autotransformer, it would be possible to have the "hot" side of the AC line connected directly to one or the other output contact. A slightly more sophisticated system has the AC line isolated only by a single capacitor, if the capacitor shorts or becomes leaky, some fraction of line voltage appears on the output. Many old tube radios were made with similar design, and if you touch any metal including the mounting screws holding it in the case, it can shock you, and if well-grounded, kill you. Millions of them were made this way, only a few people were ever hurt/killed.

          If it's a "chopper" style power supply, a failure could put anything up to 311 volts on the output.

            The wire is plenty adequate to pass lethal current, that's as little as 20 ma. Whether it is actually fatal depends on how well-grounded you are when you touch it.

  3. Ok, maybe on DIY Satellite Tracking · · Score: 3, Insightful

    Perhaps you can take and antenna and point it where you think Voyager might be with this sort of equipment. I am extremely skeptical that you can "track" it, that is, lock on to the carrier and then follow it. I bet you can't see the carrier at all, much less see the data.

    I agree, not surprising at all. If Apple does it successfully, Microsoft will come along with a failed and poorly executed copy about 3- 4 years later. Predictable as the Sun rising in the East.

  8. Re:How did it form an atmosphere? on Research Suggests Mars Once Had a Thick Atmosphere · · Score: 1

    It has no magnetic field now. The theory is that there was an active geodynamo (hey, I have used that word twice this week...) originally as the result of residual heat of formation and radioisotope decay, just like the Earth. Mars, being smaller, cooled quicker from the original heat of formation and has smaller quantities of radioisotopes for the volume, so the formerly molten mantle and core have largely solidified. I think the current theory is that the core is still partially molten but not nearly enough to generate the dynamo, and thus no magnetic field to speak of. There are still residual localized magnetic fields possibly laid down when the global field was still active but then altered by the last bit of tectonic activity (which is also essentially non-existent).

  9. And to finish the thought... on Colliding, Exploding Stars May Have Created All the Gold On Earth · · Score: 3, Informative

    In case anyone was wondering, Iron (Fe) is the limit to what is formed in convention fusion processes because any element heavier than iron takes more energy to fuse than is produced by the fusion. Iron and lighter fuse with an energy surplus, anything heavier requires an energy input and produces a deficit.

    Landing on a carrier is much more difficult because the motions of the ship and the disturbances on the airplane are random. In space, the motions of all the objects are highly predictable.

  16. Re:Mod Parent DOWN on Upside-Down Sensors Caused Proton-M Rocket Crash · · Score: 2

    Not correct. If you cannot accurately sense this rate (~15 deg/hr) you will go far off the trajectory in a 10-15 minute boost. It absolutely cannot tolerate errors of a few degrees. Checking for the proper rates is an absolutely standard pre-launch check and typically, any biases in this are calibrated out while on the pad based on the known alignment of the rocket and the lat/long of the pad.

  18. Re:What about the brown plume? on Upside-Down Sensors Caused Proton-M Rocket Crash · · Score: 2

    I am not sure about the Proton, but earlier Russian boosters used differential throttling of the engines to control the attitude. The brown is probably excess oxidizer from running it off-mixture to throttle the engine and control the attitude - in this case to chase the erroneous gyro readings.

  20. Re:2,921 pounds? on Volkswagen Concept Car Averages 262 MPG · · Score: 1

    This is not about liberals or conservatives (and I am as conservative as they get). And I have owned and own many high-performance muscle cars and sports cars.

        The Prius is a FAR superior and more practical car to a Pinto or Nova and it carries batteries. A Pinto is a notoriously crappy car, little better than a big lawn tractor. A Nova is a very crude and simplistic muscle car with nearly no consideration for safety or comfort that could not be sold on the US market today for any number of reasons, most of them good.

          I don't have a Prius, but have ridden in them and driven them. They are dandy cars for what they purport to do (and for the record, for the first 100 feet it will eat your small-block Nova for breakfast, MUCH better off the line) and perfectly practical and very economical. No one in their right mind would choose to drive a Pinto instead. The only thing I have found wrong with the Prius is that some of them tend to wander around on the highway due to the "low=drag" wheel alignment, which can easily be corrected.
