Non-rechargeable, carbon-zinc or alkaline batteries have much higher internal resistance than most rechargeable batteries (NiCd, NiMH, etc.) This means they can't release energy as fast when short-circuited, so accidental short-circuits are much less likely to cause anything more serious than the battery leaking somewhat corrosive goo. (This is also the same reason they tend to suck in devices like digital cameras, because the device draws power at a high rate, which ends up wasted as heat in the battery.)
Even in that case, yes. First of all, typically the phones aren't made to transmit on the same frequencies that other phones are listening on, there's usually a set of frequencies for uplink to the network and one for downlink to the phone.
As well, the range would probably suck if two phones were trying to directly communicate (two teeny antennas, versus one teeny antenna and one big-ass one).
There's no reason for the system library routines to care if the system has multiple CPUs. It may care if the program being compiled is single-threaded or multi-threaded (MS Visual C++ has different runtime libraries for each), and the kernel may be different for single processor or SMP (SMP or non-SMP configurations on Linux, or ntoskrnl.exe vs. ntkrnlmp.exe on Windows), but the runtime library cares not about the number of CPUs.
I believe there have been some ATA drives which have some support for delayed start - i.e. there's a jumper setting to delay spinup until they're initalized by the BIOS..
That "closed loop" business is pretty funny - where is the energy to run that coming from? It's effectively the burning of the carbon from the rods! Geez, if you're going to make something to run on carbon, just make a coal-burning car and you'll come out ahead of this.
If you want to make a car that uses solar power, then doing it the conventional way will be much more efficient. You can't make a car that runs on water, because what do you get when you burn the products of electrolysis, or a reactor like that? Water!
I believe heating oil and diesel are pretty much the same thing. The difference is primarily legal, in that it's illegal to run heating oil in a vehicle because fuel taxes have not been paid on it, hence the different dye coloring to distinguish them..
In North America, at least, regular ground fault circuit interrupters (class A) are required to trip with a 5 milliamp leakage current..

Uh, the ease of gaining access to a wireless network is not due to an inherent technology problem, it's due to stupid security flaws in the WEP protocol that allow relatively easy attacks on the encryption. That is, if WEP is even in use on the network..
Those are all devices covered under Part 15. They are not prohibited from interfering with each other, they're prohibited from interfering with licensed frequency spectrum users.
I believe that XP, at least, includes its own Sound Blaster emulation for DOS windows. Such a thing would be necessary to get any sound from a DOS program under NT-series Windows, because unlike in 9x/Me it's impossible for the DOS program to access the hardware to use any Sound Blaster emulation the card itself may have.
Many newer peripherals simply aren't backward-compatible with DOS, or have no real-mode drivers available. Not to mention if your hard disk is formatted NTFS, you can't even access it..
Point #1 hardly makes any sense, especially considering that IDE only has one device on a channel transferring at the same time, and no single hard drive gets anywhere near 133 MB/sec sustained transfer rate anyway. Looking forward, Serial ATA starts at 150 MB/sec and goes up from there.
As for point #2, tagged command queueing is now part of the ATA specification, although there isn't much support for it yet (mostly IBM drives, and apparently some experimental OS support in Linux).
And as for resources, so what? Serial ATA doesn't even have master/slave, there's only one device on each "channel", so does that make it worse then? How does this cause problems? With current motherboards (especially those that support APIC in the chipset), you really don't have to worry about resources.
Um, have you heard of bus mastering DMA? You know, that IDE technology that's been around since, what, 1997?
I have never seen more than 10% CPU utilization on an IDE drive that was running in DMA mode, even doing burst reads/writes at maximum drive speed. If an IDE drive is using 80%, then either it's running in old, crappy PIO mode, or there's something seriously wrong with the interface driver.
Porsche is not owned by VW. Porsche and VW have had partnerships for as long as Porsche has been around (Porsche uses a fair number of VW/Audi parts, for example), but they are two independent companies.
Not in North America they don't - they take hot water in from the plumbing. Even the front-loading washers here work that way, I believe, except maybe for the European brands..
1: Well, if you actually scratched away part of the tape, that would likely cause the head drum to tear it to shreds and jam the player, so no, you couldn't still watch the movie..
2: This is just due to dumb-ass authoring of the DVD - you should be able to just hit Play at that point to watch the main movie.
3: Blame the DVD Forum for that one - in order to get a license to play CSS-encoded movies (i.e. virtually all movie discs), they manufacturers HAVE to abide by the restrictions of fast-forwarding the warnings, etc.
The speeds they refer to in the testing are the actual rotational speed of the disc compared to the maximum speed in a 1X drive. A 52X-max CD reader will not spin the disc faster than about 20X or 24X - the maximum reading speed is achieved only at the outside edge of the disc.
With current IDE technology, there is really no point in making SCSI CD-RW drives - really, what would you gain to justify the extra cost? With DMA transfers, you can get CPU utilization in the low single-digit percentage range..
From the www.repairfaq.org Microwave Oven Repair FAQ:
What is significant about 2.45 GHz? Not that much. Water molecules are not resonant at this frequency. A wide range of frequencies will work to heat water efficiently. 2.45 GHz was probably chosen for a number of other reasons including not interfering with existing EM spectrum assignments and convenience in implementation. In addition, the wavelength (about 5 inches) results in reasonable penetration of the microwave energy into the food. The 3 dB (half power) point is about 1 inch for liquid water - half the power is absorbed in the outer 1 inch of depth, another 1/4 of the power in the next inch, and so forth.
How does that make it not FUD? They're still comparing OS X to 2 to 5 year old Windows versions. If you bought a new Windows machine, it would be just as good stability-wise..
