Bad idea. Many (most?) BIOSes have a manufacturer default password, which overrides the user password. Most mainboard manufacturers also don't bother changing it (you can view & change it for AWARD BIOSes with a program called modbin, which you will have to obtain illegally). You can also overwrite some of the CMOS RAM (takes about five lines of assembly), so the checksum will become invalid and the BIOS will load the setup defaults on the next boot. No more password.
The BIOS password is useless. Furthermore, even if it weren't, if you install a hardware keylogger, you will get the password anyway. If you want to do it professionally, install the keylogger inside the keyboard's case.
In short, if you have physical access to a machine, the possibilities of compromise (even non-invasive) are endless. And that's not even taking into account fake logins, trojans, OS & app exploits, etc. pp.
Dunno... shouldn't they rely on an inherently secure system, instead of security through obscurity? If so, the encryption wouldn't be compromised by publicizing the encryption hardware. Maybe they'd have to change the keys in related devices, but that's about it.
Why are they encrypting the messages anyway? I thought the missions were public, and AFAIK, hams have been listening to radio communication between the ISS and the ground for a long time.
I've got a Santa Cruz, picked it up on eBay for 30. It's a good card, but you get warbling voices in games using the infinity engine (Baldur's Gate,...), and Linux support is so-so. EAX support isn't the best either. Overall it's a good card though, especially the audio quality is great, which you notice when you use high-quality headphones.
US Government guidelines class tapes of 350 Oe coercivity or less as low-energy or Class I tapes and tapes of 350-750 Oe coercivity as high-energy or Class II tapes. Degaussers are available for both types of tapes. Tapes of over 750 Oe coercivity are referred to as Class III, with no known degaussers capable of fully erasing them being known [19], since even the most powerful commercial AC degausser cannot generate the recommended 7,500 Oe needed for full erasure of a typical DAT tape currently used for data backups.
Degaussing of disk media is somewhat more difficult - even older hard disks generally have a coercivity equivalent to Class III tapes, making them fairly difficult to erase at the outset. Since manufacturers rate their degaussers in peak gauss and measure the field at a certain orientation which may not be correct for the type of medium being erased, and since degaussers tend to be rated by whether they erase sufficiently for clean rerecording rather than whether they make the information impossible to recover, it may be necessary to resort to physical destruction of the media to completely sanitise it (in fact since degaussing destroys the sync bytes, ID fields, error correction information, and other paraphernalia needed to identify sectors on the media, thus rendering the drive unusable, it makes the degaussing process mostly equivalent to physical destruction). In addition, like physical destruction, it requires highly specialised equipment which is expensive and difficult to obtain (one example of an adequate degausser was the 2.5 MW Navy research magnet used by a former Pentagon site manager to degauss a 14" hard drive for 1 minutes. It bent the platters on the drive and probably succeeded in erasing it beyond the capabilities of any data recovery attempts [20]).
The only way to be really sure is to use an acetylene torch.
Forgive me if I'm missing something here, but the entire case is aluminum (Lian Li PC-68), inside and out. Everything is connected to part of that case and thus to the aluminum.
So your CPU, your graphics chip and all the chips on your mainboard are in full contact with your case, with no air in between, i.e. using thermal grease? Uhh huh, yup... must have been one hell of a soldering job, connecting microscopic wires to all those 500+-ball BGAs...
It also has three fans plus the one on the power supply. Now you're going to tell me fans are a misconception too?
Take some reading lessons. I didn't say that. Or are you trying to divert attention by making ridiculous comparisons on purpose?
Say what? Air is an electrical insulator, and only to relatively low voltages. Vide, e.g., lightning.
What are you, some kind of troll? Nobody was talking about electrical conductivity. But since you brought this up, it shows your lack of general knowledge. Relatively low voltages, yeah, about 25 kV/cm. Air is coincidentally also one of the best electrical insulators.
It is most assuredly not a thermal insulator. Put your hand near a cold window in Winter and see how much insulation you get.
Ok, you're definitely a troll. A simple experiment: put your hand in 212 degree hot air. Then put your hand in 212 degree hot (i.e. boiling) water. After that, hold a 212 degree hot metal bar in your hand. Then tell me which material has better thermal conductivity.
Well, as questionable an idea this project might seem, it won't kill you if the PSU is shorted. You see, a computer's case is grounded, and if you short the live wire to the case, the circuit breaker (or GFI) will trip. That's actually the reason why cases are grounded in the first place.
[...] those steel cases are [...] less able to radiate excess heat.
A commonly held misconception. The truth is, however, that unless the hot components are in direct contact with the aluminum, the air will act as a thermal insulator, and given the fact that air is one of the best thermal insulators out there, the cooling advantage over a steel case is somewhere between jack and shit.
I renamed the flash plugin (C:\phoenix\plugins\NPSWF32.dll) to NPSWF32.dll.fuckthis. When there's a page that I'd like to see flash on (about once a week), I just rename it back. You don't even have to restart Phoenix, just reload the page. The procedure should be the same for all Mozilla based browsers.
We didn't even finish killing all of Hussein's Republican Guard troops because Bush called the war off after pictures of how terribly we eliminated the Iraqis showed up on TV.
Err... no. Bush I. chose to retreat from Iraq to have a justification for U.S. troops to remain stationed all over the Middle East. They went there during the Gulf war and never left. As for the press, it was heavily (and voluntarily) censored during that time, virtually all the footage was Army-approved, and in fact provided by the Army.
Anyway, it was expected that Saddam would comply with U.S. interests after his defeat, without having to occupy Iraq and thus remove the need for U.S. 'protection' in the area. After this had proven wrong, the sanctions were put in place. Saddam remained defiant, and that's why the U.S. is heading there again.
I suspect this will be used primarily to deliver drugs
Reminds me of playing Syndicate, when an enemy agent would approach, you would pump up your agent's drug levels, so he'd flip out, run 40 mph and shoot everything that moves... I suppose that's the sort of stuff the military imagines. The next step up from patches would be implanted pumps with drug reservoirs which automatically inject you when a threat arises (heart rate going too high or low, blood pressure dropping, etc.), or allow the commander to give his soldiers a push just before an attack, by pressing a button on a remote...
Umm... Faraday discovered how a magnetic field changes the plane of polarization of light passing through it a few hundred years ago. Certain molecules can also do this, e.g. lactic acid. So, that in itself would be nothing new.
To be honest, I don't quite understand what role polarization plays in this... can anyone clear this up?

A helicopter is limited to the speed at which the blades stall.
Minor correction: the maximum airspeed of a helicopter is the speed at which the tip of the advancing rotor blade exceeds the speed of sound. Beyond that, drag (and therefore the stress on the rotor and hub) increases dramatically. There is also the effect of retreating blade stall, which occurs when a helicopter flies so fast that there is no or reverse airflow on parts of the retreating blade, but this depends on the collective pitch setting and rotor RPM.
The current speed record for helicopters is around 250 mph, IIRC.
I thought enough material had finally invaded the net for people to realize Mhz means nothing... I guess I was wrong.
You mean Apple ads?
Seriously, what 'material' are you talking about? I know about SPEC, according to which the currently fastest CPU is the Itanium 2 1000 MHz, followed closely by the PIV 3.06 GHz. From that I would deduce that even if you've got a relatively slow CPU (in terms of computations per clock cycle), if you manage to run it at very high frequencies, you'll still have one of the fastest CPUs out there.
AFAIK, the lead had an additional function as a lubricant for the valves in the motor. I mean, why would petrol companies have used a patented technology when there was a free alternative?
I don't think there is any practical problem that would prevent another moon mission. A moon rocket could be sent up in parts and assembled in space, using the ISS as a base of operations. The problem is that there aren't any scientific breakthroughs to be expected from landing more people on the moon and having them jump around for a few days. A permanent moon base OTOH would IMHO be a worhtwhile project, because it would give us the experience we'd need to start a mars mission. Maybe they could also set up a telescope, while they're at it.
The problem is, nobody would want to pay for such a project. Do you think a presidential candidate would win if he announced that he wanted to raise taxes for a huge space program?

You've obviously never played Doom. Which planet are you from, huh?
Easy solution: install two hard drives perpendicular to each other. Voilà, instant gyroscopic stabilization, and less jitter.
Yeah, but they don't want faggots in the army.
Nope. A magnetic field that would be strong enough to erase a hard drive would probably also compress it into a lump of twisted metal. from http://www.usenix.org/publications/library/proceed ings/sec96/full_papers/gutmann/:
