My server is like a beautiful exotic woman. She ignores the obvious attempts to get close to her, but if you know the right ports, she opens up. Of course, she encourages security and doesn't allow unprotected remote ehm...administration.
[...] it's worth bearing in mind that people will listen to their portable mp3 player in places where the background noise is sufficient to drown out any imperfections the compression creates.
That is true, sometimes. Sometimes the person listening will be deaf in their left ear, so shall we drop the left audio channel too?
I though the problem with NTFS was that Microsoft never released the documentation and NTFS is pretty complex, so nobody else could really know for certain if a driver was 'complete'. Has that changed, or is NTFS-3G still reverse-engineered?
Or perhaps they do know about partitions (who knows about loop-mounting ISOs but not about partitions?!) and you missed the fact that they want to use the drive for "file exchange", which I read as "exchanging files between operating systems".
An MTBF of 1 000 000 hours does not mean an average disk lasts 1 000 000 hours. Disks also have a lifetime rating - perhaps 25 000 hours for a consumer drive. The MTBF generally means that during the design lifetime, on average one disk will fail for every 1 000 000 hours of use. For a 25 000 hour lifetime, that means that 2.5% of drives will fail during their design lifetime, which is pretty close to the numbers I've seen in large-scale studies. After the design lifetime, all bets are off. No drive will last 1 000 000 hours of operation and no drive manufacturer claims they will.
Making hydrogen at STP is about 60% efficient. I've heard 80% claimed for dedicated plants. By comparison, an internal combustion engine is about 30% efficient.
That's a meaningless comparison. The internal combustion engine efficiency figure is for the entire cycle - fuel to usable power. Your hydrogen number ignores the efficiency of producing the energy to produce the hydrogen and the efficiency of converting that hydrogen to usable power.
What you described is achieving a certain device temperature at a given ambient temperature, not achieving a temperature differential. But thanks for playing.
Taking the backup tapes home with you for the night is probably the second most common disaster plan, after having no plan at all. At least that's the case for the majority of businesses, which are small businesses with no dedicated IT staff. This was not a small business with no dedicated IT staff, this was a freaking government department which likely had an IT budget in the millions.
I find it amazing that the prevalent attitude in the USA seems to be, simultaneously, that theirs is the greatest democracy in the world and that their government(s) work(s) in opposition to the people.
I don't get the point of a 5 MP camera with a tiny lens in front of it. More pixels means fewer photons per pixel, which means poorer low-light performance and more noise. More than about 1/2 way out from the centre of the image, the airy disk (roughy speaking, the size of the smallest possible dot the lens can manage when focussing a point source) produced by the 2 MP camera on my phone is about five pixels. In other words, it takes pictures at 1600x1200, but with less detail (thanks to the additional noise) than it would have with the same lens and an identically sized 0.3 MP, 640x480 sensor. Hopefully one day the public will learn that beyond a certain point, more megapixels means worse images and I'll be able to buy a phone with a well-matched combination of optics and sensor.
First you reply refuting a a point I never made, then you reply to my post quoting your post.
You evidently thought I was talking about something else, so here is the short version of my point again, as an example: You do not design the cooling system for a CPU to maintain less than a 50 K differential to ambient (that's what I would consider to be 'achieving a certain temperature differential', which is what the post I replied to said was 'the most important part of thermal engineering'), you design it to keep the CPU below 350 K. That is all.
Oddly enough, obesity seems to be mostly a disease of first world societies.
It's a growing problem in Africa too. There (where 'there' means 'much of Africa' - it's a big place!), being obese is associated with good health as well as wealth; obese women are considered more attractive than thin ones. In part this is because it's because being obese means you have plentiful food and don't do heavy labour for work, but also because being thin is associated with AIDS (known as "slim"). As Africa continues to grow wealthier, I think it may be an even greater problem there than it is in the first world, simply because it isn't seen as being undesirable or unattractive, as it is in the first world.
Fuck you AT&T, I've signed up for a 2-year contract and now I'm not going to use your service! I'll still pay you, because otherwise I won't get the phone, but I'll be using someone else's network! Chew on that, bitches! Erm, yeah, I bet they'll be quaking in their boots. All the way to the bank.
In what sense is the temperature differential the most important part of thermal engineering? Perhaps if you're building a heat engine, but this is not a heat engine. Real devices made from real materials have hard absolute temperature limits: The limits at which the materials will perform their function adequately. If (as in this case) heat is an unwanted by-product you need to get rid of, your only goal is to stay below maximum operating temperature; you do not aim for a particular temperature differential.
The fact that SSDs are faster has been mentioned, but the other major factor is the size of the market. The market for SSDs is tiny and new, with only a few manufacturers competing. The market for CF cards is vast and mature with zillions of manufacturers competing.
Make a characature of a gay person done by a straight person. I'm sure it'd be pretty offensive if we did that here or subsituted gay with spanish or chinese.
Eric McCormack (Will from Will and Grace) is straight. You were saying?
It would have cost NASA about ten bucks to include a little brush to sweep over the solar panels. A tiny little push broom that just pushes the dust off over the edge would have solved this problem--how the fuck do you build a billion dollar robot without asking a third grader how to keep them clean?
For a 90-day mission, you get more power and reliability by spending the mass of the cleaning system on just having larger solar panels and letting them get dusty. I guess NASA must have asked a fourth grader, eh?
The payoff may be 75-95% on average per play, but people tend to play their winnings. So with a 90% payoff $100 wins you $90, which you play again and win $81, which you play again and win $73, which you play again and win $66...

Unless it's, say, the CEO's laptop that gets lost. Then (s)he'll say "Why the fuck isn't backup automated?" and fire your ass.
Two questions, in no particular order:
Does she run Linux? And how big are her tits?
The problem with procedures people HAVE TO FOLLOW is that they STILL DO NOT FOLLOW THEM.
That is true, sometimes. Sometimes the person listening will be deaf in their left ear, so shall we drop the left audio channel too?

If a manager can delegate everything, including ultimate responsibility, what the fuck are they getting the big bucks for?

Every telephone exchange is ADSL-enabled because the government made BT enable every exchange for ADSL, not because of commercial considerations.
