I guess I don't get the mathematics of poverty. If I'm going somewhere with a friend, I was already going there anyway and wouldn't charge them gas money. I'd only charge if I was taking them somewhere I had no intention of going and I wanted to be a dick about it.

This is not what it’s about in general. It’s about providing a ride. Not picking up someone on the way you were happening to be traveling.

Both scales have their advantages and disadvantages. Thing is, most of the world has standardised on Celsius and is easy to convert to scientific units (kelvin).

0C means ice, 100C means boiling. Two common and dangerous points. Most everyday activity falls within that range, and it's easy to tell what something that is 80C is going to be like because it is 80% of boiling water temperature. There really is no reason to stick with Fahrenheit other than tradition.

Weather dude. It’s easier to relate on a scale from 0-100+F which you have been used to for the last 50 years, what the real temperature out there is, rather than 0-30. Well, at least it is for me, as an old fart with a physics drgree, YMMV.

Some numbers about the computing power at the CERN computing center (July 2013):

Number of machines: 17,000 processors with 85,000 cores (Source)
All physics computing is done using the Linux operating system and commodity PC hardware. There are few Solaris server machines as well, especially for databases (Oracle).

And Yes, it can run Crysis.

You are using a contrived example to "prove" your point by taking a trivial problem and taking the most absurd route possible to solve it. The "Common Core" method (which, by the way, is the method that most people will use intuitively) is used to reduce the complexity of nontrivial problems, not to make a mockery of the trivial ones.

By way of example, what's 426 - 298? Well...
298 + 2 = 300
300 + 100 = 400
400 + 26 = 426

And now... drumroll please... 100 + 26 + 2 = 128.

And you and I both know that if you had faced this problem in the real world that this is exactly how you would have solved it. You probably wouldn't have drawn a box or any such nonsense, but you would have reduced it to manageable chunks like that because that's the sensible way to solve it.

Sorry to have rained on your common core bashing session.

I really don’t get what that crap above is about, but doing it in my head I just took off 300 and added 2.

So you might think you know how I would do that problem, but you’re wrong.

Fundamentally, why are swap and hibernation in separate files? Hibernation is just swapping everything out, as if the computer temporarily had 0 RAM.

Because that way you can get back to having a responding computer in a reasonable time, since it can just do a sequential read to put the working set back into memory. Also, because kernel needs to write its normally non-swappable state somewhere - what processes are running, what files are open, what virtual memory space and address do the pages in the swap file belong to, what interrupt handles are installed, etc.

Plus your OS may actually have swapped out some memory and to to get to exactly the same state will need to access that swap file content. So overwriting with RAM contents is going to create potentially an unstable system state.

If you're not careful, you're going to catch something.

Working...
