You can't pull on one end of a column of liquid and drag the whole column up. Something has to push it from the bottom, unless its own inertia can carry it.
If you have a fluid with high intermolecular attraction (like water), yes you can.
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.
The only problems I've ever had with with Logitech mice is the scroll wheels give out, and they can't make recharging contacts worth a shit on any of their devices.
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."
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.
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.
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.
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.
The entire side of the card is one giant heatsink, shared between the two dies. The heatsink is separate from the dies by a heatspreader, basically a giant flat heatpipe, to ensure roughly equal cooling between the two dies.
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.
The death penalty is not a punishment. The death penalty is society deciding you are broken and unfit to continue being one of its members.
Lionesses?

Servers can be run on virtualized IPs, like in the ten last years...
IPs are just numbers. There's nothing physical about them. What the hell is a "virtualized IP"?

Well if it isn't... no one knows, because it's an AC.

There is no adapter that will make a rotary phone work on a touch-tone-only phone network.
Oh, but there is!

Or you could skip DTMF all together and go straight to SIP.

I have an A22 from early 2001 that still sits on the end of my desk serving as a spare UXGA X-server.

It's cheaper to send a couple drones up to tirelessly update the aerial photography in Google Earth than manned aircraft.
What happened with the idea that there can be more than one responsible party?
And what's wrong with e-cigs? All the nicotine, none of the carcinogens.
I know I saw a headline just in the past week or two saying that wasn't the case.

You do realize that "vacuum tubes" are also called "thermionic valves", right?

Water cooling is far superior because water has a very high thermal capacity, so it stays cool over a much longer period than a metal heat sink.
Are you suggesting that heatsinks work by absorbing and storing the waste heat generated by the CPU?
Except we don't use copper any longer, we use ammonia and a passive refrigeration cycle.
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.
