It's not a piece of electronics, it's a spacecraft. We have different expectations for spacecraft, although they tend to be based on mass rather than volume.
The IBM Power7 (567 square millimeters, 1.2 billion transistors) is ten times larger than the Soviet K1801VM3 microprocessor (52.6 square milimeters, 200 thousand transistors.)
Imagine a Beowulf with all of the overhead, and none of the speed.
For simplicity's sake, the team used an off-the-shelf 1994-era Pentium processor design for the cores themselves. "Performance on this chip is not interesting," Mattson said. It uses a standard x86 instruction set.
Dare to criticize and repudiate, dare to struggle Never stop making revolutionary rebellion. We will smash the old world And keep our revolutionary state red for ten thousand generations
And that's why Top500 should use another benchmark. If the beancounters use Top500 to allocate resources, and the supercomputing companies use the beancounter's allocations to determine the future direction of their products, the scientists lose out. It's not so much that Tianhe-1 gamed the benchmark, it that's this gaming could lead to a machine that's not very useful.
Your nostalgia is showing. The latest Crays don't immerse their boards in flouronert. They aren't hand connected by teams of unusually small weavers. They don't use chips clocked ten times faster than anyone else's. They aren't physically small. They do, however, have nifty interconnects-- which probably explains why Jaguar is 75% efficient, and Tianhe-1A is 54% efficient.
It's a daemon that copies files that have changed in the last hour to an second hard drive. It's useful for casual development work, and the GUI client is intuitive. I've also used it to recover files after they've been over-wriiten by buggy programs. It's also come in handy for certain games-- if the autosaved game file from today is less interesting than the autosaved game file from yesterday, or two weeks ago, I can recover the older files.
Yes, you can get the same effect by running VMS, or Git, or adhering to a regular backup schedule, but this makes it easy. All you have to do is make sure that your backup hard drive is connected, and turned on.
nvidia makes a svelte, powerful core 2 duo chipset, but is not licensed to make a similarly small chipset for the core i3/i5/i7. If apple had used an i3, they would be stuck with intel's graphics, because there would be no room for a gpu.

This is why government outsourcing is a golden opportunity.
Wikileaks and cryptome need to become commercially significant, pronto. Maybe they can sell t-shirts or something.
People thought DNA was a gay disease?
This is why Windows HPC is going to change everything

No, no, they're called notebooks, because you're not supposed to put them on your lap-- at least until the engineers devise a proper cooling solution.
It's amazing how common sense can be trampled by a couple of meaningless acronyms.
3. There is 0 fore-site on what will happen for the next version. What new features. Apple is too closed
All your base are belong to us. You have no chance to survive make your time.
The stars commanded it.
The only disadvantage is that it's slow, but so what? Voting is important, we can afford to slow down a little and do it carefully.
Somehow, Al Franken managed to be 7 or 8 months late on his first day of work, all because of delays in paperwork.
We'll compromise.
$100 billion for space
$100 billion for welfare and war
$100 billion for tax cuts
$300 billion in debt.
Why can't we have ads like that in the US?

Check out Step 15 The Ram is circled in yellow. No sockets that I can see.-- it looks like surface mounting.
Frankly most laptops and netbooks don't let you upgrade the CPU.
You're right. Most don't. You can't upgrade your way out of obsolescence, you can only stave it off by not buying obsolete parts in the first place.
You can order an xserve with redundant power supplies. You can even add them to an existing xserve

AMD has this problem solved...
