The reality is that those peace loving civs that you talk about really did stagnate and would have collapsed from internal issues even without neighbors.
War really is good for progress, and even for people as a whole; although clearly not for the people who have to live - or die through it.
Remember that war is not usually genocide, it usually more about who you pay taxes to and who's the king then anything else. The average person didn't much care, and didn't loose anything either. So any advancements remained, and were simply absorbed into the larger cuture.
There are exceptions of course: the crusades for one. But most of the time it was a game of kings.
A: you don't need to heat an egg to boiling to cook it. Eggs start cooking at 120 degreess. (50C) So you only need an extra 30 degrees, not 80. By your math that drops the time to 1.7 hours.
B: It doesn't take 1 calories to heat 1 gram of egg 1 degree. That's true for water, which has a record high specific heat. An egg is nearly all protein, which has a much lower specific heat - possibly 5 times lower (just a guess). That brings the time down to 20 minutes - which is what the article says.
"I don't understand... Since when does a head ever come in contact with a platter surface?"
Every time you turn it on and off. Really. It rubs on the surface until the platter spins fast enough to provide lift (like a wing) for the head. That's why I keep mine on 24x7. IBM patented a head load unload safety ramp to stop this from happening. But as far as I know no one else uses it.
"In my experience, that usually creates a truly frightening sound and an extreme amount of data loss..."
No, the noise (if you hear one) is bearings that died.
Also, the hd parks it's heads before letting them touch the surface, so they touch a special area of the platter that has no data on it.
"set the hard drives to spin down after 30 seconds"
You better have good backups. Desktop hard disks aren't designed to spin up/down that often. Remember each spin up and down means contact and rubbing on the head surface.
I'd be suprised if the hd lasted more then a year.
Laptop hd's are (hopefully) designed with loading technology that move the heads aways from any contact at all with the surface. They do that a: for spin up/down and also b: so you minimize the risk of a head slap, what with laptops moving so much.
Also, with a 3.5inch disk, the energy used just to spin it up is more then the energy used in letting it spin. Approxmiately a spin up costs as much as 30 seconds of spin time. 2.5 inch disks are much lighter, and they are designed to read data before it's fully spun up.
"Kind of like the old adage that goes something like "Discipline your child often."..."
OMG that is the most horrible piece of advice I have ever heard. I hope you were using it sarcastically, because if you actually did that to a child you would have the most horrible miserable child on the face of the planet.
Have you ever been punished for something you didn't do? You NEVER forget it, and you NEVER forgive either. It eats at you till you can find some way of revenge. I'll prove.... (most likely that I can do something really bad and get away with it, to balance out the unfair punishment.)
And even if they did do some minor thing, if you constantly discipline someone, they never learn to discipline themself. You never trust them, so they never trust anyone else, and they never learn to contain themself either.
At the most extreme you get kids like that elf on harry potter - they do something bad, and punish themself, then do something bad again. They never learn that it's bad to do something bad - all they learn is that if you get punished then the bad thing is neutralized.
And what happens if every single person who was the best for the job was white, or asian, or some other homogeneous mix?
You'll get complaints that you are a racist company, and then they'll force hiring you to hire some other-race person, even if it's not the best person for the job. That's what will happen.
So I don't buy your argument, in theory it just might be true, but in the real world preception is everything - you might want be a very non-racist company and hire the best persons, but in the real world that just won't happen - they'll force you to hire worse people just so that you'll look less racist.
Why don't you download it? I didn't check, but I'm sure it's available. That way if it's a good movie, maybe it will have a chance - especially if you encourage other members to do the same (or give them a copy of the download).
Sorry but you are wrong. I did some tests on a snowy day. I sped up and then stopped. If I carefully pushed the brakes to not let the car skid I stopped quite nicely. On the other hand when I slammed the brakes, I went into a skid and the ABS kicked in, I slowed but not very much. I had something like 2 to 3 times the stopping distance.
In fact one time (on a different day) I nearly rear ended someone before I let up on the brakes. Figuring out the proper brake pressure is really not that hard - just ease up until you stop skidding and hold there. (BTW the car is a 98.)
ABS is all about control - it doesn't help with stopping. It lets you stear while slamming on the brakes - but if you don't panic and press lightly (no pump or anything) you can do much better.
OTOH many people do panic, so ABS is good to have in general.
Rigggghtt, you worry that governments should not be able to take control of domain names. Instead they can just send a few agents to the guys house with a gun pointed at his head. (Whether the domain owner, or the domain registrar.)
Unless you are supporting nations not having control of their own domain I think govenment control of the registrar is the last thing you need to worry about. First you should worry about government control of it's army.
They do want the results of the test, but they will send you a new drive even if the test finds nothing - but only if you can give a good reason why. My hard disk started making loud clicking sounds, but the test came back perfect. After talking to them and explaining, they are sending me a new disk.
And BTW for linux users they have a bootable floppy or CD that you can use.
"....and most of those optimizations are disabled as soon as the compiler sees an unconditional jump..."
Wow! You got that EXACTLY backward!
I hope that was a typo, but I'm guessing not.
Anyway all the stuff gets disabled with a conditional jump! An unconditional jump is nothing, a CPU can optimize that very well - in fact it's not even executed in the standard sense of the word, it's optimized away at an earlier stage.
Erm, no I'm not. You double the voltage, you half the amps for the same watts (and we were talking about watts).
"Also, there's no such thing as "2-phase" power (think about it, they'd cancel out...)."
And so what if they cancel out? They are supposed to. That's why there is no neutral, just the two phases canceling out to make 240V. (Do you think the power vanishes when it cancels out? It doesn't - it gets used.) But you are right, it's not called 2-phase, it's called split phase. Technically anyway, but most people don't bother and just call it 2 phase. Read here: http://en.wikipedia.org/wiki/Split_phase
"Standard home electricity is 120V single phase, where as industrial power is 3-phase at either 240 or 480v."
Nope. Standard home is 2 phase, (ok: split phase), at 240V. (120V for each half of the split.)
And 3 phases is not 240v anyway. It's much more complicated then that. You could consider it as 624V if you wanted (but no one does). Basically each set of wires in a 3 phase system are at 208V (there is no neutral). Add up the three possible combinations, and you get 624V.
The only things that actually use all the phases are electric motors. You can also run heaters, but it's really just 3 seperate heaters, balanced so that you don't need a neutral.
And yes, 208V, not 240. (They are at 120 degrees out of phase, rather then the 180 degrees common in housholds.)
No it's not. It's 2 phase did you forget? The amp rating of a breaker is at 240V. (Or equivalently you can say it's 100A or 200A per phase, for 200A or 400A total.) (Is it 480V in EU?)
293.4 / 2 = 146.7. That sounds about right compared to what the gp wrote.
And why would you convert this to DC anyway? And you don't need any 1.4 factor - it's 120V RMS - it's already factored in.
Natural selection is not the same thing as evolution!
Yes I know that lots of people think so.
Natural selection is one species becoming more populous then the other. But both species already exist. Nobody has any problem with this, because it's not evolution - although it's a pre-requisite for evolution.
Evolution is something else entirely - it's a new species showing up were none existed before. And please don't both me about minor changes (arms getting longer, or the like). I mean truly radical changes - going from living in an egg, to nursing for example.
That is what people have an issue with, and it's hardly scientific either! It can't be proven or tested experimentally.
But it has some drawbacks: there are no generators that can produce it. The 50hz was chosen because that was the max possible at the time, and 60hz was chosen because tech improved to that point. (Also the AC motors used could not be made to work at a heigher frequency, and that might still be a problem.)
Also, it's never gonna happen - too much established infrastructure. Airplanes use it though (but they have turbines for generators, which would not be practical on a larger scale).
Um, your story was nice I guess, but it also wasn't true.
You were wrong with your explanation of FTL galaxies, nerves don't strech. And longer nerves don't increase wisdom. And why exactly do you think peripheral nerves think? That would be the brain. Nerves mixed up in circles? Hu?!? They sure don't.
Reaction time does slow down I suppose, but not by much.
Slashdot Mirror
What about /swap? Do you mean the swapfile partition in linux? That too uses a 4K page size.
Um, it already does take up 4K or more. Unless you have a hard disk smaller then 256MB.
p pro/reskit/c13621675.mspx and scroll down to Table 13-4
See: http://www.microsoft.com/technet/prodtechnol/winx
If you notice, in most of the useful cases the custer size is 4K. Making the hard disk match this seems like a good idea to me.
And EXT2 also uses a 4K block size.
Also remember it's for large disks, no FS that I know of supports a cluster (or block) size smaller then 4K for large disks.
"Many people think the extra time to read the book is worth the additional depth."
What extra time? A book with the same amount of plot even plus additional depth, as a comparable movie, can be read in less them half the time.
Of course most books make up for that by adding more story/plot.
You're confusing what you wish for with reality.
The reality is that those peace loving civs that you talk about really did stagnate and would have collapsed from internal issues even without neighbors.

Make yourself a little file called /usr/local/bin/qfind
Put this in there:
find . -iname "*$1*"
use qfind to find a file in the current directory and downward.
Note: Not all finds have iname (case insensitve iname).
"Where did you get 20 minutes from?"
From thin air? I really don't know. Somehow that's what I remembered.
And you are right about the water level of an egg, looking at the Nutrition Facts I count 11g of other stuff in a 50g egg, AKA 39g of water AKA 78%.
I now acknowledge that this is a hoax. There really is no way for a cell phone to cook an egg in 3 minutes.
Except:
A: you don't need to heat an egg to boiling to cook it. Eggs start cooking at 120 degreess. (50C) So you only need an extra 30 degrees, not 80. By your math that drops the time to 1.7 hours.
