  5. Re:New connector great thanks on Next-Gen Thunderbolt: Twice as Fast, But a Different Connector · · Score: 1

    Thunderbolt is absolute garbage to me and I'd rather have a USB 3.0 connector.

    The issue is that Thunderbolt is really not a peripheral connector, but a dock connector, or external data bus. Its intended purpose is to connect your laptop to a device (or maybe a monitor) that offers a range of static ports, so you do not need to plug them all in individually. It was never supposed to be a direct competitor to USB.

    What really made USB popular was when USB 2.0 hit, and again Apple had nothing to do with it. PC manufacturers started adding more USB ports and it became easier to attach a number of devices. Who would attach a keyboard and mouse when their machine only had two USB ports? HP in particular was one of the companies that helped develop USB 2.0, and they started moving to USB keyboards and mice as standard around then too.

    What really made USB popular was that it was cheap shit. There was practically no licensing cost on the interface, and all you needed was a few pennies worth of host-driven IO. When it makes no difference to your bottom line, of course you put a dozen of the fuckers on a machine. Your mouse and keyboard really need no significant performance, so who cares if it's on a slow, CPU-hungry interface, and even things like (consumer grade) scanners and printers benefit more from a small, hot-attachable plug than they do from a hardware driven interface.

    When you start trying to use it for storage, or cameras, or network interfaces, or monitors, or anything with any real data rate, now the cheap shittiness of the interface of the interface rears its ugly head, but it's too late, because it's already the pervasive peripheral interconnect. This is why Apple was trying to hold out with Firewire over USB

    I remember reading that of the $20 million cost of a launch only about $500,000 was due to fuel, so this is a complete game changer.

    Right idea, but wrong numbers. A Falcon 9 launch, not including the cost of the payload itself, is nearly $60M, while the fuel for it is only a quarter million.

    No. Ignorance is the ability to learn, combined with the lack of knowledge. I suppose you could claim some genetic trait for motivation that prevents you from going out and acquiring knowledge, but that's a bit of a stretch. Stupidity, on the other hand, is the simple inability to learn, and can be inherited, thus the statement, "Ignorance can be fixed, but stupid is forever."

  17. Re:Producing them is one thing on Samsung Claims Breakthrough In Graphene Chip Design · · Score: 1

    That is correct. When you excite the outer shell of electrons, causing them to jump to a higher energy state, and allow conduction, you have added energy (heat) to the system. However you want to go about supplying that heat to the system, you have heated it up, and heating it up has in turn make the semiconductor conductive. It is a thermally regulated electric device.

    Yes. You apply an electric field to the semiconductor, energizing a percentage of the atoms beyond the band gap, opening up holes to allow conduction. You add energy to the system. In other words, you raise the temperature.

  19. Re:Producing them is one thing on Samsung Claims Breakthrough In Graphene Chip Design · · Score: 1

    Yes. That is how a semiconductor functions. At low temperatures, you're below the band gap, requiring energy be supplied to excite the atoms, bump electrons to a higher shell, open holes, and increase conductivity. At high temperatures, you're above the band gap, and you can't function because you're always a conductor.

  20. Re:Producing them is one thing on Samsung Claims Breakthrough In Graphene Chip Design · · Score: 1

    What controls the band gap? Supplying energy to excite atoms and cause electrons to jump to the next shell, opening up holes that increases electrical conduction. What defines the amount of energy in an atom? Heat. What is the measurement for bulk heat density? Temperature. So, as temperature goes down, the heat content goes down, and energy state goes down. The semiconductor becomes an insulator. As temperature goes up, heat content goes up, energy state goes up, and you're now a conductor. Hence, semiconductors are fundamentally thermally controlled electric (thermoelectric) devices.

    If your chip's temperature brings the energy level above its band gap, your semiconductor will simply not function, and this temperature is well below your semiconductors functional mechanical limits. If your chip's temperature means the energy level is well below the band gap, your semiconductor will need to run at a high core voltage and consume a large amount of power to bring the energy level (and temperature) of the gates up such that they will conduct and switch.

  21. Re:Producing them is one thing on Samsung Claims Breakthrough In Graphene Chip Design · · Score: 3, Insightful

    The problem is that transistors are thermoelectric devices. You switch them on and off by heating them up to change their conductivity. Silicon chips can withstand temperatures well beyond the point at which the plastic packages they are mounted to break down, but that temperature is also well beyond their switching point, making them useless as a computational device.

    If you could produce a semiconductor that was useful at 3000F, then that would be its normal operating temperature, and you would need to feed it a high enough core voltage to allow it to heat itself up to that temperature to switch.

    In fact, heatpipes being a form of phase change cooling, are much more efficient than pumped water at short and medium ranges. The only issue with heatpipes is that the average hobbyiest can't make them themselves, and they require static routing.

    There's no problem with convecting your heat near the thing you actually want to cool, so long as you can get enough airflow there.
