nguy: Symbian's APIs are not even close to being "Linux-like". They use their own (really horrible) version of C++, and it's really difficult and painful to write and debug Symbian apps as a result. The iPhone is not anywhere close to being the worst there is!
That's right, and in fact the pressure is slightly lower than it is at the same altitude closer to the equator (latitude less than 30 deg.), because the earth's rotation pulls some air away from the poles and towards the equator. So even though the Pole is at 9900 feet, the pressure is equivalent to an altitude of 10600 feet near the equator.
I worked there for a couple of Antarctic summers, one month each time. It definitely takes a couple of days to get adjusted. And there are always a few people who CAN'T adjust to the altitude and have to be sent back to McMurdo.....
Yes, the sum does include matter and energy. Yes, energy does indeed contribute to the total gravitation of the universe.
Your other point is kind of interesting, actually. At very early times, when the universe's mass/energy density was much higher than it is today, there was enough electromagnetic energy around to keep most matter fully ionized (charged) and therefore the universe was opaque to light. It's because we live in a time where the EM energy density is low that we can see across the universe!
We got a cell phone package for my family that included Samsung A650 phones. My mother in law let hers go through the washing machine (!!!!!)
I took out the battery, let everything dry out a bit, then put the battery back and plugged it in. The phone worked fine, but you could still see some water that had gotten inside the screen. After a few days, even that went away, and now the phone is as good as new.
I can't recommend Samsung phones highly enough.....
What about people who need to get around on wheelchairs or scooters (I'm friends with a number of such people)? Seems to me that hard surfaces do have SOME advantages over "solid ground"....
For the beginners, I agree about the O'Reilly books (Learning Perl, Learning Java, Practical C Programming, etc.) A good intermediate one would be the O'Reilly book "Mastering Algorithms with C". For advanced books, you can't go wrong with the books by Stevens ("Advanced Programming in the Unix Environment", and the series on TCP/IP networking), and the Dragon book on compilers ("Compilers : Principles, Techniques, and Tools" -- Alfred V. Aho, et al.)
All of the above books are really good -- the advanced ones have been around for awhile and have stood the test of time. There is also source code available for the examples in all the above, with the possible exception of the compiler book.
They don't dig out the entire volume; the photodetectors are placed on cables and lowered into narrow holes about 60 cm wide and 2 km deep. The holes are melted using high pressure hot water. After the photodetectors are lowered in, the water freezes back into ice. So most of the detector volume is actually pristine ice. At the large depths where photodetectors are deployed, the pressure "squeezes out" bubbles and cavities, and the ice is very pure, so light can travel long distances and few photodetectors are required to cover a large volume...

This is how good Samsung products are:

I used to work in such a plant. I think most production line people in that plant would be happy to be an IT manager instead :)
Hard to believe that hardware will really be free -- guess it depends on what kind of hardware.....
