Here are the top fp results from www.spec.org, showing the best Power5 system, best Itanium 2 system, and best Opteron system. All are single-core chips. The Itanium 2 beats the Opteron by a huge margin. The columns after the system name are the max/sustained fp results. There's an even faster dual-core I2 (with an "elegant" dual-core design) on the way, and it has some crazy power-management system on it that enables it to use less power than the current single-core I2. The Itanium 2 is wildly successful in the HPC segment, a niche product nonetheless.

The problem is, the great-grandparent poster had something to say, but it was not intelligent. Posing as someone who has a deep understanding of something and "educating" others on the topic is very bad form, and it brings down the quality of the discussion. It really brings down the signal to noise ratio. The great-grandparent poster's knowledge of logic design and VLSI design was too shallow to be posting on the subject of asynchronous vs. synchronous ckt design. If you're interested in the subject one (very dry) source is "Contemporary Logic Design" by Katz. You'll also want to learn about VLSI and EE to figure out why implementation of large-scale async designs is challenging.
Admitted, the grandparent poster's comment wasn't very helpful, but hopefully it kept some readers from pondering the great-grandparent poster's nonsense.
No, you cannot use atapwd to reset it. There are two passwords, a master and a user. If you know the master password, you can use atapwd to reset the user password. These passwords are stored across platters and are stored as a checksum in flash on the HD controller. Resetting the password is not trivial at all. There are two options, use a logic analyzer and try to intercept the pieces of the password on it's way in to generate the checksum (haven't heard of anyone being able to accomplish this), or take the drive apart in a clean room, erase the password of the platters and attach a virgin controller. There are no companies in the US that will do either of these for you, and I don't think that's a coincidence. The very few (3-4) companies that perform this service make very good money of it. If you don't believe me, set your master ATA pwd to a known value and try to reset it by any means _without_ using the password. You can't, you're hosed. Most people at this point chuck the disk, they're cheap. But if you need the data you'll pay anything. The idea behind it is that should it get stolen, the data is safe. The companies that do data retrievel require proofs of ownership. However, for the fool that forgets or accidentally sets the password, you're hosed. For those of you that own Toshiba 80GB laptop hdds, beware, there's a flaw in the controller that may glitch and set a random password for you. In that case you'll want to talk to Nortek.
Intel's Montecito is the best CPU man has made to date. 1.7+ billion transistors, two multithreaded cores, 24MB L3 + 2MB L2I +.5MBL2 cache, 2-something GHz, and it's power efficency is incredible -- something like 100W max power. If the lazy arse programmers would stop suckling up to x86 and adopt a modern architecture we might be able to dump x86 and finally move forward. Fat chance if mainstream will actually adopt a stream processor like Cell. It's a great idea, came out of some research at Stanford. Thing is, running anything other than multimedia is a bitch. If you think compiling code for IA64 is tough don't even bother with a stream architecture. Slashdot continues to suck...
The next Itanium chip will stuff two multithreaded cores on one die and use _less_ power than the current generation Itanium/P4. It also reportedly sports a whopping 24MB on-die L3 cache. It also has dynamic power management technology where the chip will give you max frequency for a given power envelope. It continuously monitors voltage and thermals and sets the frequency accordingly. Very cool/tricky stuff to do in a process/supply voltage that's set up for digital design.
That's several thousand CPU cycles on today's chips, and even more cycles for future chips. These cycle-stealing earthquakes must be stopped! STOP PLATE TECTONICS!
I don't have the charset to write it up here, but those of you that are familiar with it no that there is no bound (no pun intended) to it's utility. Here's a link to the equations on MathWorld.The extensions of this theorem, the Laplace integral and Z-transform are equally important. These equations enable us to project functions of time onto periodic functions which we can then use to analyze the frequency content of the original function. They also enable us to easily solve differential equations and discrete difference equations.
According to my inbox, there is an abundance of high-quality vacuum chambers available for a good price. We should have no problem recreating "space" for research here on Earth.
The orginal buttons-round-the-wheel interface was much better than the 3rd gen 4-buttons up top interface (I hated it). The mini's click/touch wheel is the perfect melding of the original wheel/buttons interface, just awesome. This is great, I wish I had gobs of money to get a new one, but my 2nd gen 20GB is still chugging away healthily, no battery problems or anything. Another great product from Apple!
It's talking about the kernel, not the GUI. But they're still not correct. The two differ dramatically in their methods of IPC, process spawning, etc. About the only correct point made is that they have similar ancestors, and even that is suspect -- VMS is not UNIX, they differ again by things like IPC, etc -- some of the same differences between Windows and Linux. This article is a TROLL!
There's something for modders to work on -- they prefer their machines to sound like a VTOL aircraft landing on a swedish death metal band
That's one of the funniest things I've ever heard, mind if I make it my.sig? It's especially funny in the context of my swedish death metal kick of the past couple years (the result of a search for new metal bands after metallica not only put out shi**y music but got the RIAA on all our backs). Actually, that'd be pretty awesome to have a JSF F-35B on stage at an In Flames concert.
It's a great read. It gives a brief history of UNIX and competing OSs, then describes in depth properties of the UNIX OS and contrasts them with other competing OSs. If after reading this book you're still developing on Windows, it better be only because your company says you have to. If that's the case, I'd be trying to convince them to begin migrating to a UNIX-like platform.
This book gives great guidelines for programming in general and is a must have for any serious programmer.
There is something to be said for code that can fit entirely in the L1 cache, especially if there are separate I & D caches. Cache misses are expensive, at least with this code you'll only be using the bus to fetch data instead of instructions.
Hehe, a little late checking up on my/. The current iPods are considered "3rd Gen", the 1st is the original 5GB, and the 2nd Gen last year's 5-10-20GB models. I greatly prefer buttons around the scrollwheel, and the new mini (got one for my gf) is the perfect mesh of buttons/scrollwheel, Apple really nailed it with this one, best interface on an mp3 player, ever;)

can a computer program created by the professor be used to find Quality if the professor can't define it himself?
I guess you could say dark energy is comprised of "fake ghostlike photons"? (No, I'm not affiliated with ThinkGeek).

I know it wasn't that popular, but it was somewhat enjoyable. The probes have obviously hit the edge of the simulation ;)
I don't think naming chips after elements is as bad as naming your OS after big pussies.
