The EDGE architecture gets rid of relying on a single register file to communicate results between instructions. Instead, a producer-consumer ISA directly sends results to one of 128 instructions in a superblock (sort of like a basic block, but larger). In this way, hopefully more instruction-level parallelism can be extracted because superscalars can't really go beyond 4-wide (8-wide is a stretch...DEC was attempting this before Alpha was killed). Nice concept, but it doesn't solve many pressing problems in computer architecture, namely the memory wall and parallel programmability.
I agree that a bus has scalability limits. But in AMD's coherence protocol, even with fast HT links and NUMA structure, every miss requires an entire system-wide snoop (just like Intel). The difference is that AMD also always fetches data from DRAM on every transaction.
Attributing Microsoft to massive death in Africa and supporting the nuclear attack on Redmond is an example why nobody will take you or your like-minded peers seriously. Ever.
The HT technology is better, but the way it is used for cache coherence is pretty lousy and inefficient. Every cache-to-cache transfer (used to communicate data from one processor to another) results in stale data being sent from DRAM to the processor as well as the correct current data being sent from one processor to another. That is an entire wasted DRAM access and data response. On the other hand, Intel FSB has a sane bus-based snoopy protocol that does not result in unnecessary data responses.
Bah. I'm still using an HP LaserJet 5p printer manufactured in 1995. I go through a toner cartridge about every 3 years or so. Prints B&W at 600dpi. Never jams paper, never fails. The occasional color print goes to a lab or Kinkos. I tried shotty inkjets, but none were as robust, reliable, or cost-effective as my good ole' Laserjet.
I placed my WiFi router in my basement. I can pick up the signal anywhere in my house and about a 10-foot perimeter around my house. Anything beyond that the signal is too weak (including the road) with the several WiFi adapters I've tried. Forget WEP...don't need it!! This allows friends to easily use their laptops inside my house without bothering with WEP setup.
Yeah yeah yeah...so it ain't perfect and maybe someone could use a super-sensitive receiver, but if someone is gonna try that hard to sniff my network, they might as well break in my house when I'm not home.

Have you ever written an interrupt routine to service high-priority power-management events in a real-time operating system?
How am I suppose to know that Google wasn't contacting me for my lower-level embedded systems knowledge and experience? Hell, apparently Google is working on cell phones now.
Well I'm a PhD student in Computer Engineering at a highly ranked university. I don't claim to be "smart". However I work hard, I can hold my own when it comes to coding, and I have professional software engineering experience before I started grad. school.
Google contacted me for an interview (I never applied). My phone interview with Google grilled me on undergraduate algorithms like graph traversal. Thats pretty much it. Now my undergraduate degree is actually Electrical Engineering, but my graduate research has been mostly software development. I'll admit I didn't remember details on many algorithms (never actually took an algorithms class), but I'm sure I could code up Diikstra's Algorithm once I read it over from a textbook.
Needless to say I was quickly rejected from Google. Why they contacted me for an interview and then tested me on things I have little background on, I have no idea. The interviewer even admitted to me that he actually doesn't use any of this stuff in his day-to-day job.
Thus I'm skeptical when these companies claim that they can't find people. They may have a hard time finding people that fit the exact cookie cutter they are looking for.
Another great free tool is called Picture Cooler. It rivals or exceeds Noise Ninja for certain images. Download it here: http://denoiser.shorturl.com/
But if you want images with less noise, try and buy a camera with a larger sensor. dSLR's have large sensors as do many Fuji cameras including their tiny P&S models. Most sensors on subcompact P&S cameras measure only 5.76x4.29mm (1/2.5"). Many of the smaller cameras by Fuji use a 1/1.8" sensor that measures 7.18x5.32mm.

Whatever. Of course Microsoft is gonna save money by not devoting to development to hardware that isn't sold anymore.
But I'll admit, since I make a living researching processor design, I am happy to see Microsoft demand more powerful computers. Otherwise I won't have a job if people stop buying new machines.

Ok, thanks for the arbitrary definition that a 20-year old PC is obsolete, but that a 4-6 year old PC should be considered a viable platform for development. You should make a law out of that.

I just installed Ubuntu Edgy on a 400 MHz Gateway G6 with 256 megs of RAM. I had to go into the command line twice to get all the extra 1998 hardware working, and the responsiveness felt just a tad sub-optimal.
Ubuntu Edgy is just a few months older than Vista. I wonder how Vista would have fared?
I'm pretty sure there is a new version of FreeDOS that is just a few months older than Vista. It would probably do quite well on my old 25MHz 80386 machine.

Yes, becase computers have fundamentally changed in the last four years.
Yes and No. General-purpose computers haven't "fundamentally" changed in 50 years. They are all von Neumann machines. On the other hand, the number of transistors on a desktop microprocessor has at least quadrupled in the last 4 years.
I'm not gonna try installing Vista on a 80386 machine either.
The U.S. tried to isolate itself from the rest of the world in the early part of the 20th century. Then WWI and WWII happened. Were those wars the fault of the United States? Of course not. The politics of Europe allowed a dictator to come to power and systematically slaughter millions of Jews. WWII changed the world and created the military superpower that is the U.S. today. The rest of Western World (including Europe) relies on the U.S. to be the military superpower.
