Sorry, guns the the hands of any one that has no official government supervised reason is insane. The US has statistics that clearly demonstrate that having guns so readily available leads to unwanted results.
The US has statistics that clearly demonstrate that having knives so readily available leads to unwanted results. How does the availability of firearms lead to a proportionally high statistic for knife assaults and murders?
EOS failures can do funny things. Single IOs can fail while the rest of the chip works fine. It's hard to catch such problems. Ideally during startup, you'd run a test on every pin to make sure they're all still working. Even if the lightning strike occurred immediately before the crash, I would hope that after being hit by lightning they'd stop and test their systems.
It is trivial to catch such problems. There are alternative circuit designs which are immune to open, closed, and stuck at failures. Usually this involves AC coupling and charge transfer instead of DC coupling and voltage or current levels but using multiple output or input pins along with synchronous circuits can provide much of the same protection.
Industrial control systems where catastrophic failure is possible or human safety is at risk are where such designs are usually used.
I'm all for reducing government meddling (like repealing drug laws), but self-regulation is a myth in this day an age. Take the history of phosphates in detergents. When the government (rightly) forbid phosphates in laundry soap, many said that it was meddling, despite the fact that ground water was being polluted. Moving the goalposts, people then claimed it was impossible to make an effective laundry detergent without phosphates. Yet here we sit with clean clothes and clean groundwater. Wash, rinse, repeat (pun intended) for banning phosphates in dishwasher detergents.
I installed new dishwasher a couple of months before phosphate free detergent was required here and the result was I had to run the dishwasher more than twice as long to get dishes which were not quite as clean. Now I add the TSP manually and run it twice as long anyway.
I tend to think of it more as an obsession with intermodulation distortion. All other things being equal, small speakers will have more nonlinearity than big speakers at a given power level because of larger displacement. That yields more harmonic distortion and with the lack of a good crossover a lot more intermodulation distortion and the later makes for the boomy sound that is popular.
Listen to the Aliens soundtrack on the typical underdamped small speakers which are popular today and you will have to turn it down because excessive bass overwhelms the rest of the soundtrack and makes it difficult to listen to. Play it back on a critically damped set of bass reflex speakers and you will have to turn it down so the windows do not crack.
I don't know if this is true or not, but there has to be some characteristics that a receiver (if friend then foe) can discern the signal from real noise.
Spread spectrum modulation would allow this. If you have either GPS access or accurate clocks, then the receiver can be initially synchronized with the transmitter even though the spread transmission is significantly below the noise floor. Accurate timing is necessary to limit the code space to be searched.
The coarse acquisition code for GPS does this but the code area to search is small and the signal is not spread enough to hide it.
At least where I have lived, air conditioners had a heat output that was a fraction of the pool heater's heat output. You could indeed replace the air conditioner's air cooled condenser with a liquid cooled one which uses the pool water but to get the same heating effect as your existing pool heater will require the air conditioner to run several times as long.
A small 50,000 btu/hr pool heater is about twice as powerful as a 3KW air conditioner after you account for the COP and you need to use the pool heater more during the times when you do not need to operate the air conditioner.
Of course, using the pool as a heat sink for the air conditioner's condenser would raise its COP and use less energy for cooling the house so it might be worth doing anyway. Just make sure not to operate it dry and make sure it never freezes with water in the heat exchanger.
Your post reminds me of a story I heard about military procurement and Cobra radar detectors.
Apparently during some air force war games, the Americans noticed that the Israelis (?) were very adept at breaking missile lock-on so they asked about it. The Israelis pilots showed them these inexpensive Cobra radar detectors that they had mounted to the inside of their canopies which just happened to work great against the newer American targeting radars and gave the pilots an early warning. Not to be outdone, the air force then contacted Cobra about ordering a special batch made to military specifications and was rebuffed. Cobra told them it was not worth their time submitting paperwork and making a custom model and that such an order was too small to bother with. Not to be denied, they removed some of the requirements but Cobra still declined. Finally, they asked that they just be painted green and Cobra agreed.
Since the government can revoke your permission to drive under a variety of circumstances (and I think that we can all agree that intoxicated and blind people probably shouldn't be allowed to drive), by definition driving is a privilege, not a right. Your participation in driving on roads funded by the general taxpayers is essentially an agreement between you and society to enjoy and share the benefits of roadways for transit.
Since the government can revoke your permission to [vote, keep and bare arms] under a variety of circumstances, by defintion [voting, keeping and baring arms] are privileges and not rights.
The G4 Cube only overheated if you covered the vents. Admittedly, putting the only vents on the top of the computer, which was a flat and a seemingly prime spot to set something down, was a minor oversight on their part. And by minor, I mean the opposite.
Consumer products often have curved tops or irregular shapes to prevent stacking when cooling is an issue. I try to avoid such products figuring that they were marginal designs in the first place.
I suspect the biggest obstacle to cell tower generator backup is the required permits. You would want to use propane like they do with remote towers for easier cleanup and longevity.
I have telephone service through U-Verse and the CPE is on its own battery backup which is plugged into a big online UPS which also feeds my cordless phone base station and some other network gear.
Since the physical transceivers are part of the cable they could always release an optical version of the cable later which presumably would have longer range. I assume they did not because it would have been more expensive at this time and 2 meters was enough for consumer applications.
A passive optical link would have precluded Mini DisplayPort compatibility. As it is now, the same connector is doing double duty. Compatibility also prevents just doubling the number of signal pairs so a passive cable could have been used.
I suspect they could have done the cable equalization on the computer and enclosure side but the power requirements would have been too high for portable systems. 10GBASE-T is not known for low power yet.
It is not that simple. The problem is that the impedance discontinuities of the connectors at either end of the cable are a significant problem at the signalling rates needed for 10 Gb/s full duplex so at least for a consumer product, it may have been cheaper to use an active cable rather than a passive one.
DisplayPort and HyperTransport manage it but both either use more conductors or are not full duplex.
It beats SATA because it is not locked into ATA command set. Thunderbolt routes PCIe I/O, which means you can build any PCI peripheral and it will work as if you plugged it into the main board.
So at best you have traded using a somewhat standardized SATA AHCI driver for the same driver you would be using for any other custom disk or RAID controller unless of course the disk enclosure includes a SATA AHCI controller putting you right back where you started. Plus the cable is available externally for hot-unplug tests which are made even easier since the connector lacks positive retention. It's also 25% faster than the PCI Express 1.0 x8 link which my several years old internal RAID card uses. What a deal!
To be fair however, it is a great solution for adding external storage to a sealed laptop used as a desktop replacement if money is no object.
Western Digital no longer publishes the internal organization for their drives but 126 MB/s over 500 GB yields about 1 hour and 6 minutes to read the entire drive in the best case. It is proportionally longer of course for larger drives since only one head can be read at a time and head switches require at least the same amount of time as a adjacent track seek.
Without physically raising the spindle speed, I do not believe it will be possible to lower the time to read the entire drive significantly. The spindle speed is no doubt frequency locked to an on-board oscillator so I might try swapping the controller board with one modified for a higher spindle speed and then reading the drive. There are a couple of ways to go about that including raising the frequency of the reference oscillator or changing the phase locked loop divider that the spindle motor driver uses. RPM detection no doubt uses back emf sensing so fiddling with the spindle position sensing is not an option.
All of this will be for naught though if the read channel will not operate at the higher frequencies involved and the drive may simple fail during calibration or detect an out of scope parameter and shut down. Reverse engineering and reprogramming the firmware it outside the scope of what I would attempt without significant time and funds.
If I had a drive or two to sacrifice I could try something.
If it's anything like the 880G chipset option, only certain cards will work with Hybrid CrossFireX. I'm not sure why this is the case. My 880G has a 4250 onboard but only pairs with a 5450 for Hybrid CrossFireX. My 5770 cannot utilize Hybrid CrossFireX
I found the same problem with my 790GX. The highest performance card which would operate in Crossfire mode with the chipset GPU was too small to be worth buying and lacked the ports that I wanted anyway. Having the integrated graphics is still handy though for driving another monitor or two.
Even without GPU differences between generations, if there is too much difference in performance Crossfire or SLI will not work. The cost of the setup will exceed the gain from the lower performance GPU. It would be better to use the lower performance GPU for physics calculations if possible.
I have thought about but never seen a clutched supercharger with a bypass. Seems like an awful lot of work compared to just changing the pistons or maybe the rods assuming there was enough valve clearance in the engine.
Through what? Both amplifier output and speaker have very low impedance.
They are not low impedance at RF frequencies. HF and MF typically get in through the unshielded and unfiltered power amplifier output leads and get rectified by the output or driver stage changing the amplifier bias. Shielding and filtering the line level and lower level inputs is obvious. Doing the same for the outputs is not.
At least this is the case with linear output stages. I have not seen this happen with class D amplifiers yet.
Induction depends on magnetic field going through cross-section of the loop formed by wires -- if that was noticeable, speaker wires would be twisted.
Induced common mode RF can be just as big a problem. Twisting or not will not matter in that case.
People who don't know Ohm's law?
What does Ohm's Law have to do with it? High power shielded cable is available for these applications although some marginally stable power amplifiers may have trouble driving the additional capacitance. If you want to be clever, you can even wire every other conductor together in a ribbon cable which being flat goes under rugs really well but it is a lot of work.
Let's keep in mind that I'm talking about a possible high-end integrated solution that doesn't exist yet. This device would be NUMA-like, and have a high-speed memory on a wide bus optimized for the GPU, in addition to a classical memory optimized for the CPU. Still, CPU and GPU can access each other memories with higher performance than in a current discrete GPU solutions. Think about a multi-core Opteron memory organization, but instead of being symmetric (all memory ports identical) the ports are optimized for either CPU or GPU.
I am not sure this is physically or economically feasable. Not only would the CPU require a lot more pins but additional area around the CPU for the soldered on memory would be needed. I had not noticed that graphics cards have a whole lot of extra room around their GPUs.
GDDR5 chips are 32 bits wide so two are used per 64 bit channel. How many 64 bit GDDR5 channels would be required to make the performance improvement worth the area and pins needed? Would it be better just to add additional standard DIMM channels?
I have an E85 Sonoma but E85 it is not cost effective given its price and the lower MPG it yields.
How much improvement would be gained by changing the pistons to raise the compression? You would not be able to use regular gasoline but would it be worth it?
Interference you can hear in speakers is picked at the input of an amplifier, or over power rails.
Or picked up at the output of the amplifier. Shielding the low level inputs from interference is obvious. Shielding and filtering the power amplifier output is not and who uses shielded cable between the output and the speakers?

It did not help when we sold Magnequench who was producing for the military to them and they physically moved the entire company to China.
