You realize that star trek reference (the star trek enterprise episode title) is itself a reference to Corinthians in the new testament, right? And that it's not the only time star trek has referenced it... another translation comes out not as "in a mirror darkly" but "through a glass, darkly", for the same passage, which Picard says in Star Trek Nemesis.
Plus many books have used the same reference too.... but now I'm rambling.
I'm glad you read the article carefully enough to point out flaws in the submission. I do, however, disagree with the following:
"People's lives do not depend on the development of software--especially Microsoft software, thank god."
Ever think that mistakes in software -- even just in poorly designed interfaces -- have been directly responsible for wrong medical procedures or analyses or the like? Or that because of software flaws (some of which can be attributed to MS, but obviously not all), people's identities have been stolen? I completely beg to differ. People's lives these days depend critically upon software. And it's only going to become moreso.... (time to enforce higher-quality code.... from EVERYONE)
Good points, but wouldn't the metadata (time of day, and date) be embedded within the original image files? Plus, the approximate lattitude should be easy to determine given that they already have everything mapped onto the earth.
I'm not arguing that everything would be able to be modeled, but every bit helps.
I'd like to see this applied more directly to something like Google Earth. They already have the "show buildings".... this would be a great boon to that. It might need a different shading than the grey boxes used by Google earth as it stands now, to show which structures are derived from the 2d images, but still, I think it'd be great.
There are various projects that take differing views about how to do this. One class of such processors are "run-ahead" microprocessors. The idea here is to allow invalid results to be executed but not retired by a second processor running up to a few thousand instructions "ahead" of the processor executing real code to be retired.
There are several variations of this. One is to use the second core to run in advance of the 1st thread, the first thread effectively acting as a dynamic and instruction-driven prefetcher. One such effort includes "slipstreaming" processors, which works by using the advanced stream to "warm up" caches, while the rear stream makes sure the results are accurate, and to dynamically remove unecessary instructions in the advanced stream. Prior, similar research has been done to perform the same work using various forms of multithreading (like HT/SMT, and even coarse-grained multithreading). See the www.cs.ucf.edu/~zhou/dce_pact05.pdf for more details.
Others, such as Dynamic Multithreading techniques take single-threaded code and use hardware to generate other threads from from a single instruction stream. Akkaray (at Intel) and Andy Glew (previously intel, then amd, then...?) have proposed these ideas, as have others. Some call it "Implicit Multithreading".
Now, the register article is so wimpy (as usual) that there's no actual information about what technologies are used, but maybe it's a variation on one of the above.
Then when does the list of theories end? Teach creationism too? Hindu theories of creation? Bhudist? Aztec? Eventually the list gets too long and people learn nothing about everything.
Too bad you'd then have to rely on your devices radiating their energy away in the electronmagnetic spectrum (probably Infrared?). I dare say it'd probably just burn up if you could feed it the energy required to run.
That's funny and all, but if you're counting via integers (and individual dollars) as 2^32 + 1 indicates... well, I hate to break it to you, but 5 billion is more than an unsigned 32-bit integer.
Have you tried the tabbrowser extensions? Check under the "advanced" tab. Although I only have the linux version, so I can't say if the tabbrowser extension works under OSX....although I don't see why it wouldn't.

Up to 10x the surface area of the sheet of metal? Sounds like it could make for a great low-profile heatsink. Of course, development costs could be prohibitive, but still...
Actually hyperthreading, being SMT, allows it to tolerate pipeline flushes better because when one thread stalls, the other one can just take right over. You're right in that hyperthreading just helps keep more parts busy, but what you're missing is that when there's a branch mispredict, or there's a data dependancy and that data is not in the L1 cache, there's a LOT of work that the other thread can do. He's right -- hyperthreading does indeed help longer pipelined designs just fine.

Other/Other - None 8 August 2002 The Armadillo Rocketeers
You'll believe an armadillo can fly
In Mesquite, Texas, a small group of technicians and enthusiasts is quietly working to open space to the general public. Armadillo Aerospace is one of a growing number of start-up ventures attempting to accomplish what NASA and the big aerospace companies refuse to do: send paying passengers from all walks of life into space to find their destiny or to have a bit of fun.
Computer games guru John Carmack started Armadillo Aerospace to fill the void--literally and figuratively--left by space agencies and defense conglomerates.
"I first got bit by the space bug about two and a half years ago," says Carmack, "largely due to the Space Frontier Foundation's CATS prize."
The CATS (Cheap Access To Space) Prize was offered to the first private group to build and launch a simple unpiloted rocket to the edge of space (100 kilometers, roughly 62.5 miles). The CATS Prize competition lasted only a limited time, and as no team reached the desired altitude, the prize was never awarded. But several teams made significant progress in high-altitude rocketry in the attempt.
"I didn't have the skills to actually compete at the time," says Carmack, "but I funded the last year of work for two of the teams (JP Aerospace and SORAC) while I was building my knowledge base. When I was ready to start pursuing my own projects, I contacted the local high-power rocketry society to see if there were any local people interested in working at the high end of experimental rocketry."
With that, Carmack began assembling his team. Through the aforementioned high-power rocketeers, he met Phil Eaton, who had been working with Russ Blink on experimental hydrogen peroxide rockets. Eaton brought in Neil Milburn and Joseph LaGrave. Carmack then drafted his Ferrari mechanic, Bob Norwood, to help out. Today, Armadillo Aerospace includes two more members and, according to their web site (www.armadilloaerospace.com), an armadillo named Widget. The staff (except, presumably, Widget) got to work not only on designing but also building rocket vehicles.
Recently, Armadillo Aerospace has built and flown several small, unpiloted vertical takeoff and landing ( VTVL) craft for low-altitude testing. The Armadillo team has chosen to start their development program using simple hydrogen peroxide rockets, not too different from the propulsion system used in the "rocket belt" jet packs of the 1960s. This simplifies development while the team uses the landers to perfect their flight control system.
"Our entire three-axis, stabilized propulsion system is less complicated than a single one of XCOR's LOX/alcohol engines," says Carmack, who is an investor in XCOR and supports their work. But, Carmack says, "we are taking complimentary directions to space."
Armadillo is now developing a piloted lander scaled up from the smaller craft. "I would not expect anyone to go higher than about 50 feet with it," says Carmack. "In theory, it could build up about 100 m/s velocity if flown flat out, but that would be a bad idea, given the lack of streamlining."
The X-Prize, the US$10 million award for the first private team to send paying passengers on a sub-orbital spaceflight, then do it again two weeks later, is Armadillo Aerospace's ultimate goal--one that John Carmack thinks he may have a shot at winning. But the team first plans to cut its teeth on several additional vehicles. "Our first streamlined tubular vehicle will be flying soon (unmanned)," says Carmack, "but it will only go a few thousand feet high. The next vehicle will be a manned vehicle aimed at breaking the low altitude time-to-climb record. After that will probably be a vehicle aimed at a single-man space shot. Then it will be time for an X-Prize vehicle."
The program reflects a conservative build-and-test strategy for winning the X-Prize. "The teams that think they are going to build an X-Prize vehicle on their first try are kidding themselves," warns Carmack. "Mistakes will be made, and it is much better to make mistakes with smaller vehicles than larger vehicles."
Each vehicle teaches Armadillo Aerospace what to do and what not to do in building and flying a tourist rocketship, from perfecting the attitude control system to selecting the right design for the landing gear. "We hope to be proving our laser altimeter based auto-hover and auto-land soon," says Carmack.
While development of the interim vehicles is underway, Armadillo's engineers are already designing the X-Prize vehicle. "We have already gone through two prospective designs," says Carmack, "so there is a high likelihood that what we are currently thinking is not what we will be building in 2004."
The vehicle will most likely be vertical takeoff and landing, and it will probably use hydrogen peroxide and kerosene, though Armadillo is also working with other propellant combinations. "We have not nailed down exactly what combination of parachute / rocket thrust / rocket rotor will be used for descent," says Carmack. "We will be learning a lot with our upcoming test vehicles."
The 2000's are an exciting time for commercial spaceflight. The dream of access to space for everyone is becoming reality. And Armadillo Aerospace plans that one of the pioneering companies to open this new frontier will include on its staff an armadillo called Widget.
Do I have to point out that MHz doesn't always equate supremley with "speed"? I'm not an apple zealot of an AMD fanboy, but the metric of "speed" is how fast can something be accomplished...and a higher frequency is only one means by which to expidite the completion of a task.
You say that MHz is "shorthand" for speed now...I find that sad, because it is extremely shortsighted (as is clamoring about IPC), but I digress.

Well, that's what the scrolling text reads. The little blurb next to the picture and "1975" reads:
"...develop a BASIC computer language for the Altair 8800."
So at least in one place they were a little more humble....
