That happens to work both ways, so he is entirely legal in recording this conversation (and is usually a very smart idea, in case someone decides to disagree with anything they said before).

    I go to PSU as well, living in the dorms at University Park.

    The reason you are seeing excessive speeds is because Napster has a local caching server on the PSU network. If you're living in the dorms they have only 10Mbit network connections, so what you were seeing is the maximum network bandwidth (I know this is true in West Halls, not sure about the others).

    And yes, I use Napster all the time when I'm down there. They got a fairly big collection, although I'm starting to see a lot of more "pay only" tracks as time goes on. I also strip the DRM out of the songs with a nice little program called tunebite. You may want to check it out. ;-)

    They don't even use servo's anymore (though, servo's and stepper-motors are the same thing). Current hard drive technology (well, for the past 10 years or so) use voice-coils, much in the same way a speaker is moved. Servo drives often required a low-level format to recalibrate the tracks to the current position of the heads, since time/heat could position themselves outside the track boundry. The voice-coil system can do this all on the fly. (And yes, the clicking heard by today's drive is from the heads moving fast enough like a speaker to produce sounds).

  4. Re:Hello, Itanium... on Octopiler to Ease Use of Cell Processor · · Score: 3, Informative
    More familiar than you may think. Some of the first Itanium compilers were spitting out nearly 40% NOP's, which are simply do-nothings. Because the IA-64 is explicilty parallel, instructions are generated and bundled together to be executed in parallel. The problem is branches, which destroy parallelism since they can change the code direction. On average, there are about 6 instructions between branches, so, such a design is very costly since the memory controller will be stuck getting inscructions that are empty. Of course, speculation and branch-prediction is generally a good way to increase performance, but like many things on the IA-64, that's left to the compilier to figure out. These are some of the exact same problems with the Cell, although, I wish I knew how the instruction set was. If it's more like Itanium, then they got all of the problems of the Itanium. If it's more of a direct approach, they may be able to pull it of because of the work in multi-processor systems that are done today. But, they simply can't expect the "super-computer" numbers Sony keeps flashing around. It may be good on certain tightly coded scientific calculations, but when it comes down to real-world code, it's stuck to the stripped-down Power4 that is coordinating the Cells.

    That's not even entirely correct. Centrino is an extremely clever marketing tool. It consists of the processor, chipset, and wireless chipset. Only those who sport all three components from Intel get the little Centrino sticker on the outside.

    A lot of systems (particularly Dell) went with thier own, much cheaper, wireless solution. Their sticker was "downgraded" to the plain Pentium M. The i855 was used no mater what, although some certain ASUS motherboards can adapt the Pentium M to another chipset/motherboard combo, although that's limited to desktop machines.

    My guess this will not be well suited for automotive applications. Car alternators actually produce more like 13.8 volts while running, since lead-acid batteries require a higher voltage source to charge. Also, automotive electrical systems can swing wildly when kicking on power-draining devices such as headlights and air conditioners (the auto industry is starting to setup a 40V spec to help power these systems while keeping the voltage stable).

    I believe current auto computers have a hefty filtering package to work under these varying conditions. The Pico-PSU doesn't seem to have enough filtering to be directly plugged in. However, a smaller external voltage regulator to handle the spikes/drops would probably do wonders for it.

  9. Umm... Radiation warning? on Retrofitting an iPod into a Geiger Counter · · Score: 1
    The server is down to a crawl, so I have to ask the crowd. My high-school physics professor had a few of these. They're civilian gieger counters built for Civil Defense during the cold war. He had a few of them, and managed to scrap parts to get one to work. He was demonstrating it, and a newer model, on some very mild radioactive sources he stored wraped in lead.

    Then he pointed both readers to the side of the old gieger counter, and both beeped with activity (far faster than the other pre-packadged samples he had). He went on to say how they kept radioactive samples on the side to both test and calibrate the sensors. They had to be near 50 years old, but they were putting out about twice the activity of the 5 year old samples.

    Makes me wonder if his model had one, and if so, if he bothered to remove it. I doubt the radiation is harmful even in extended close-range contact, but methinks the hard drive won't appreciate it too much.

    A mirror is of course a simple practical solution to the problem. But there are caveats. A mirror allows you to see around a corner, but it could also just as easily let the enemy know where you are (tilt it just wrong and it will be like a beacon). Not to mention a mirror is a tad bit fragile in a combat situation.

    The military has used other solutions over the years. The use of a spit-shined combat knife worked extremely well for this (as it was standard issue to all soldiers). Newer technology has allowed the military to mount cameras onto the barrel of their M-16 and a small heads-up display (much like some helicopter head-up gear) is used to view. It allows them to reach the gun around a corner and view the area and even aim and return fire if needed. The camera is multi-purpose since it also could switch to night-vision.

    The SWAT would probably like this more, as close combat allows them to bounce the ball around a corner and down a hall a little nicer. The ball itself is probably heavily weighted in one side (probably with the batteries) so that it would right-side-up.

There are no attempts at comparing the system to anyone elses silent cooling system (or active systems, for that matter). The whole review gives the feel that this is ExtremeTech's first 6600 to fall upon them.

    What really bothers me, though, is they give no tempreature readings whatsoever. How much does the CPU temp go up with the radiator above the heatsink fan, or to the side? What are the temps on the card, with and without active cooling? Would you need to upgrade your CPU heatsink/fan to keep the processor from overheating?

  15. Re:Argh! on ATI Launches Crossfire... Finally · · Score: 1
    Quite true. But how many PCI Express nVidia cards anymore DON'T support SLI? My point is, if you purchase a nVidia solution, you will require a SLI motherboard. Buy any middle-to-upper end nVidia card and it will support SLI. That means the other card is a drop-in solution.

    This isn't true with ATi. You can buy a Crossfire motherboard and you can buy any middle-to-upper range ATi card without problem. If you want to use Crossfire, you have to purchase a specifically built Crossfire video card (which would cost more than a standard video card, for various marketing reasons).

    ATi's system simply is more restrictive. ATi won't be making every video card they have Crossfire capable, since this would me more expensive than the plain-jane setup (that extra chip adds more than you think).

    If I were to be ATi, I would have designed a new incompatable system (the limited compatability is practically the only benifit of Crossfire). I would have desinged the motherboard so that each PCI-E slot was selectably 15x or 16x wide. In Crossfire mode (that would be enabled by the BIOS, not by some stupid jumper-block setup), both video cards would run at 15x, and the remaining channel would be tunneled between each video card. (This is, of course, assuming that only one PCI-E lane would be needed. It surely could be expanded.) The next product cycle, I would make everone of my PCI-E cards Crossfire enabled, and crack-down on the specs so that even differnt generation/manufacture cards would work (Inter-manufacture would be far easier than inter-generation compatability, this I will admitt.)

    What benifits would there be? For one, an external cable between video cards has been completely eliminated. A drop-in soultion would be gaurnteed without need for an extra product. It's clean, simple, elegant, and expandable (as more channels could be eaten up for inter-card bandwidth. PCI-E 16x has WAY more bandwidth than the cards need.)

    But, this is dream land, and such things didn't happen.

    PS: I love ATi. I was a first-adopter of the Radeon 9700 Pro. They messed up with Crossfire, methinks.

  16. Re:Argh! on ATI Launches Crossfire... Finally · · Score: 5, Insightful
    The Inquirer discussed this limitation before. The Crossfire system can do 1920x1200, but only at 52Hz. The SiI 1161 chip on the Crossfire card that merges the two data streams has this bandwidth limitation, and it appears ATi won't be fixing it for awhile.

    Personally, I feel the Crossfire solution has far too many drawbacks for the benifits. Not only do you require a special motherboard, but now you also need a special Crossfire capable video card. The second card can be any card, but the RAM buffer should be the same size, otherwise it will defualt to the lowest value for both cards. The external cable adds some nice external heft to the system, as well.

    So, what do you get over the SLI system? There are added antrisropic filtering methods and increased anti-ailising, but these are already appearing in the latest nVidia drivers. You can use your exisitng card to upgrade to a Crossfire system, but you can already do this with SLI. All in all, the system has it's flaws, too many I think to make it worthwhile.
