Pick any point in space you want. The universe has a certain angular momentum around that point, which is conserved. It is unnecessary to find, or define, the "center" of the thing to measure its angular momentum -- just pick a point. The particular value you get depends on what point you choose, but it is always conserved.
Furthermore, rotation is not a linear motion, therefore can always be detected in an inertial frame. The only way you could fail to notice the rotation of an object is if you were also rotating with it, and if that were the case you would detect the presence of internal forces (the forces necessary to maintain the rotational motion).
What about ESP is "extraordinary" to you? Is it more or less extraordinary than: time dilation, matter-energy equivalence, the atomic bomb, quantum tunneling, the Internet?
It's not about how you feel while you're doing it, it's about how you feel afterward. It's okay if you don't "get it" and I agree that this particular case is a bit off the wall stupid, but please realize that it's a personal preference to eat spicy foods, not a sign of stupidity.
It's similar to other things. For instance, hiking 20 miles a day, which I used to be in shape for. It wasn't about the exhaustion and the pain -- it's about how you feel after doing it. If I just wanted pain there are less complicated ways of satisfying that need.
If the restaurant really believes the food is "too hot" and actively discourages people from ordering it, why are they offering it in the first place? Let's be real, the warnings and disclaimer are just a form of marketing to hype the restaurant and its unbelievably hot food.
Right, but try and use those sentences to predict and calculate the magnitude of those forces. How is that going? The reason this seems to be significant is it allows us to model these forces beyond the the explanation of "the oil sticks together".
The headline is "We finally know why oil and water don't mix" which seems to suggest that what has been discovered is more profound than just an improvement in accuracy of calculations. It makes it sound like humanity is a bunch of idiots going "Derrr, the water no mixie with the oil, we dunno why, derrrr."
What happens when you put 10,000 sports fans in a stadium and light it on fire? I can predict there will be a lot of running, panicing, people falling and getting trampled, some burning deaths, general mayhem. I cannot tell you the exact rate of egress of people-per-second, or tell you how many will die from crushing vs. burning, but I can in general explain WHY the people attempt to exit the building when it catches fire. The title of this article under this analogy would be "We finally figured out why people attempt to exit the building when it catches on fire" when the article actually talks about how to predict the types of panic, rate of egress, ratio of causes of death etc.
Sorry, that's actually a kind of fucked up analogy but whatever
For a business with 100s or 1000s of PCs, spending an extra $50 on more RAM just because it's cheap means thousands or 10s of thousands of dollars. Code bloat means we have to. We would prefer to save the money.
You want to spend $50 less on RAM and just use "non bloated software?" You are assuming such hypothetical software would cost no more than $50 extra per machine. As a developer, when you tell me "don't bloat your code," you are telling me several things. First, to rely less on third-party libraries with their accompanying baggage. Okay, but this will require me to implement things I'm not an expert at, which will take me more time and money to do, and probably increase your ongoing costs because of reduced quality (I can't be an expert at everything, there's a reason I delegate to third party code for things I don't know how to do very well). Second, you want me to favor certain programming languages over others, reducing the pool of skill I have to draw from and increasing the price of my employees.
You might save $50 per machine but you'll probably pay at least three times that much in software costs.
On the other hand, if you're using open source software, I think the general attitude is "fix it yourself." Better get on it.
Dirty pages do not sit in cache very long. Not just for performance reasons but because when you write something to disk you actually want it to be written to disk. Most disk cache pages aren't dirty and can be reclaimed through the following algorithm: Step 1: use the page for something else instead of cache. Step 2: There is no step 2.
I recently lost a coworker to the same disease. Obviously I didn't know Steve Jobs at all, but it still feels like another body blow. Fuck cancer. Stupid piece of shit buggy firmware is what we have there. Hopefully my friend is now chatting it up with Steve somewhere non-corporeal.
Further, if you're being investigated for some reason, your transponder may not be enough evidence ("Just because my car was parked outside that bank doesn't mean I was... I was nowhere *NEAR* that robbery!!"), getting pictures of you driving through toll gates at specific times may be enough to invalidate your alibi.
I'm confused. Given that you've been accused of a bank robbery, and given that you're innocent, and given that your attorney has advised you to answer questions and provide an alibi... Why would you give a FALSE alibi? WTF?
If I was a government who wanted to keep a closer eye on the citizen's Internet traffic I might decide to start a fake corporation who offers "alternative" DNS service, then get people to switch to it by pissing them off. No more need for warrants etc, all the DNS traffic just goes straight through my own servers now.
You choose your entire operating system based on a single feature that could easily be provided by a third party application you could probably write yourself in 10 minutes using VBScript? Well your head is certainly screwed on straight...
Laugh all you like, but if people actually took that advice a few years ago we wouldn't have AIDS anymore.
We'd also have a lot of rather awkward wedding nights. "Does it go here?" "Is it supposed to leak like that? Are you broken?" "I'm not sure, but I think that might be the wrong spot to put that." "Well that didn't seem to go on very long now did it?"
And what does curing diseases have to do with cyborg augmentations?
No disease to take you out early --> slow physical degradation of body components ("wearing out") --> miserable quality of life --> desire to replace worn body parts with artificial ones
That post was nice and dramatic and everything, but SUA was a piece of shit that nobody used anyway. If you need to run POSIX applications on Windows there are ways to do it that don't suck. "Hegemony," "rise to power," give me a fucking break dude.
It's not like House. Diseases have many facets which may or may not express themselves. Thus it isn't a process of elimination, it is a problem of expectation maximization. This is of course another sort of problem that computers are quite good at solving. It just isn't generally available. And if it were, mystics and paranoiacs would decry it and demonize it. hope things work out for you.
I'm not saying the stuff that the guy who got convicted sold was a perfect clone of the Cisco gear, but if it were, what would be "fake" about it, and would it matter? Does it matter to the bits that flow through it?
Are you serious? When you had a problem with your "Cisco" equipment and called Cisco, do you think they'd help you out with your counterfeit gear?
How to double your profits selling arms: sell to both sides of the conflict.
I imagine myself detaching both my arms, selling them to two large mafiosos and watching them beat the shit out of each other with my bloody severed appendages. Of course, I'd be left with no arms, but that's not the weirdest part of the image now is it
What sort of "investment" is it to put money into company for a second or even a day or a week?
I know, right? It's just like banking, you deposit a dollar in the bank and a second later they've loaned that dollar out to someone else! It's insane! What kind of person holds on to a dollar for just a second?
We ought to just get rid of these stupid banks. If I need a loan, fuck the bank. I'm going to talk to my next door neighbor, see if he can loan me $50k for a new boat. Enough of these liquidity-producing middlemen.
They do not. Exceptions improve performance by moving error handling code out of the main path of execution, increasing instruction cache effectiveness. They also eliminate all the instructions necessary to check function return codes, and defer error handling to the moment an error actually happens. Given a good implementation of the exception mechanism, they are nothing but win.
You can get into trouble when you start using try{}/catch{} blocks in complicated ways, particularly, nesting them inside each other. This is always a sign that you've designed your code wrong. try{}/catch{} should be used only to make decisions about what to do when an exception happens. All other sorts of stuff that needs to happens when an exception is thrown, such as deallocating containers and releasing resources and so on, should have been handled using proper RAII techniques without any try{}/catch{} at all. A well-designed program that uses exceptions may have literally hundreds of throw statements per try{}/catch{} construct, perhaps more. If you are writing try{}/catch{} all over the place, you don't know how to use C++ effectively.
The real downside to using exceptions, particularly in embedded environments, is code bloat. Most implementations use (rather large) object lifetime range tables to figure out which objects must be destructed, and in what order, when an exception is thrown.
Depends how you mine it. If you are constantly throwing material down to Earth, then you get this problem, but if you just anchor on the surface of the asteroid and perform your mining operations there, the net change in momentum is zero as you mine, and you only need to deal with the problem when you're done and ready to start sending material down. Honestly, I'd just keep the material in orbit until needed.

What is the "negative racial connotation" of the word "cracker"? I always thought "cracker" referred to a dumb racist, usually Southern.
A racially charged epithet which is used to refer to a group of people who use racially charged epithets, you don't see any irony there?
