The main problems I have with cooling fans are cheap-ass companies who decide to save a couple of bucks by using sleeve bearing fans. I can understand this (somewhat) on cheap power supplies, since they're....well....cheap.
But on Wednesday, I come into work and find that the previous night's backup had failed. Tape in question won't even erase. Go into server room, and see that the tape is still in the drive and won't unload (Quantum Powerstor DLT changer). Check the back, and find air blowing from the power supply fan, but nothing from the tape drive fan. Replaced it with a new ball-bearing fan, and the drive seems to be OK, but who knows how much lifespan was reduced, not to mention the three DLT tapes which were no longer happy after the problem and are now trashed. This is cost-cutting, pure and simple. If you decided that a sleeve bearing fan had some desirable characteristics over ball bearings, you could use a fan that reports RPM, or an airflow switch, or even a thermistor to shut down the components when the fan fails....
The later NeXT Turbos used a smaller fan, but had the power supply laid out on top of a long, finned heatsink. The fan blew across this, rather than pulling air across the power supply components like a PC. Of course, this sort of elegance costs money...:)

When Steve jobs created the NeXT workstation he designed every cable to be one long 10 foot single cable so that the machine (almost quiet) could be hidden insode a closet or put very far from your monitor! He hates noise of all kinds.
Maybe he designed it that way, but that's not the way any of mine are. My Mono ones have a short cable, and the Color ones make like even more fun with the sound box stuck in the middle of it all...
Well, look at the price of cartridges compared to the printer. Hell, there's the Apollo, or the HP 656c that cost less than the replacement cartridges. Toss the damn printer when the cartridges run out and buy a new one. (Of course, for those us who are old enough, Apollo in a computer context means something completely different.)
For the value to size ratio, you can't beat swiping print cartridges, which is why most stores have moved them behind the counter.
This goes right to the heart of a big chunk of FUD regarding Open Source software. I've seen it stated over and over, that you don't have anyone to hold responsible for problems with the product. I always thought, "I'll believe that one when someone gets a judgement from MS from damages caused by one of their products".
One of my friends is doing work on making Linux safe for hard real-time applications. While researching, he found out that in at least one instance, an aircraft's autopilot did its equivalent of bluescreening; it blocked off all input and output for several seconds and showed "Please Wait" on the consoles.
I think you're referring to the fly-by-wire system that Airbus introduced. There's classic footage of Airbus showing off their plane at an air show, and it flies right into the trees at the end of the runway, ignoring the pilot's inputs. IIRC, this system had some sort of safeguard built in to prevent the pilot from accidentally doing anything stupid, but the problem was that it sometimes blocked input that wasn't stupid....
Pretty much everywhere in the U.S. a bar or a party host is subject to liability if a person has too much to drink there and then goes driving. That's why most bars make it a point to cut people off when they're obviously drunk, and offer to call them a cab.
Is Gould responsible for the disconnected story lines that have been going on lately? For example, the one where Bart is digging a hole in the backyard at the beginning. They follow that thread for a few minutes, then go to something completely different. Same thing with the other night and the Gay Pride parade.
Sure, those bits had their funny parts, but they were completely disconnected from the rest of the show, as though the writers lacked the talent to come up with enough story line to fill an episode.
Whee! Another device that the color-blind to be pissed at. Invariably, they always use red/green. If manufacturers wanted to make things useful, they'd set things up to use blue/red, blue/green, or something a little easier for people with this problem.
Sort of. First, it's Fen-Phen, which is short for the combination of fenfluramine and phentermine. Both drugs were approved as appetite supressants for short-term use (a few weeks). One was approved in 1959, the other in 1973. It was only in the late '90's that doctors starting prescribing the two drugs in combination for long-term use. This is "off-label use", IOW, it was being prescribed in a manner that differed from that described by the FDA approval. Heart-valve defects showed up only in those patients who took the combination for prolonged periods.
What bugs me as weird though, is the fact that the car had a new angine at a little more than 33000 miles. I know that Ferrari's are not really known for longevity, but the engines are commonly seen as the best parts of the entire car. How can you kill an engine with that few miles? He must have a terrible driving style... I don't think I would buy that car based on that info.
Well, it was either Romero or Carmack who was featured in Car and Driver a few years back. Whoever it was, they didn't give a shit about longevity....they just did mods to boost performance.
The article was great, as I recall, but unfortunately, C&D's archive on their web site doesn't go back that far.
Uh, yeah, hydrogen is abundant. However, the very thing that makes it such a great energy storage medium is also the main problem: it likes to make very strong bonds.
You can't just go plucking hydrogen as you describe. It has to be broken free from more complex molecules, and that takes energy.

Anyone who dis's the segway sucks. IMHO
:)
Did you notice in their little chart comparing the Segway and a Huffy, they spelled "pedal" wrong? Are we sure Taco didn't write this for them?

RPM = Revolutions Per Minute
The plural is built in, thus no need to tack a "s" on the end.
We all know that Apple doesn't promote music piracy; they promote software piracy.. :)
Yup. March 2002. The comparison is online here.

Imagine if, after all the car commercials boasting airbags, crumple zones, etc, those safety features turned out not work
You mean like airbags actually killing children and shorter people, even when properly restrained?

The problem is the "line" that the red-light camera uses to decide when you're in the intersection is not indicated on the road surface.
Yellow light timing has also significantly decreased over the last few years.

And let's see...is "24" going to continue after the day is up? And they already show it twice a week anyway.
And what about Dark Angel? The only thing it has going for it is Jessica Alba.
Greg the Bunny looks like it may have some promise, but Andy Richter? Jeez...
Even better is that timothy posted both of them....

Nah...I was careful to leave out any disparaging remarks...unless they want to read something into the smiley....
Hook up that exciter to a dummy load and you won't have as much problem... :)
And I'm sure the officer that responded had a repeater in his car to tie in to his handheld radio....

L. Ron Hubbard has written a book too... :)
