  1. Re:Won by Intel? on AMD Introduces the Athlon XP 2200+ · · Score: 2, Insightful

    Not to take sides, because honestly, I really don't care... But Intel is hardly leaving the x86 behind.

    Intel's IA64 strategy is banking on a few things.

    One, that x86 doesn't have much need for 64bit support. They don't think much of our software would be benifited from a 64bit CPU right now, so they aren't going to give consumers a 64bit CPU to use yet. In general I agree with this, for now, it isn't like Microsoft Word would benifit all that much from being 64bit.

    Two, the people that do need the 64bit CPU will be in the price range of the current Itanium based computers. These people are those that do scientific calculations, intense server stuff... not Quake players.

    Three, they will have the IA64 technology optimized and proven in the future for when it is time to completely drop x86 from the planet, and the software houses will have a head start developing for it.

    Basically I think they are using todays Itaniums to get a head start on what they want to have 5 of 10 years up the road for main stream computers.

    Now this isn't to say I particularly like the IA64 architecture... but that is what Intel is doing.

    I guess what I am really trying to say is, don't count out the x86 CPU from Intel, they aren't through with them yet. I beleive they were aiming at 5~10Ghz with Pentium 4 like x86 designs... which is obviously way ahead of where they are now.

    I guess the real test will come when we see how much x86-64 software comes out. And what kind of performance increase comes with it over 32bit versions. Intel could easily have not extended there x86 to 64 bits just to try and bully the software industry into not shipping much 64bit x86 software thus negating any advantage AMD x86-64 might have over Intel x86-32.

    Not to take the side of Intel... but as an Electrical Engineer with a good amount of interest in microprocessor design I have to say I like Intels move away from x86. X86 is definitly not even close to the best computer architecture out there.

    It does make most sense for AMD to spend there time building a 64-bit x86 processor then it does a completely new architecture atm. But that doesn't mean we wouldn't all benifit greatly from dropping x86. Of course this can't be an overnight change, but it does need to happen.

    Eventually you have to break backwards compatibility to move forward without making things ugly. x86 is old, it is overly complex, it is inefficient in many respects, it is time to say good bye. There is a reason the original designers only expected it to be a 3-5 year temporary solution.

  3. Mute point on Smart Cards Vulnerable to Photo-Flash Attacks? · · Score: 1

    This is really nothing new. Anyone with some knowledge of circuits and a logic analyser has always been able to watch the data flow from the smart card. This will allow you to figure out the passwords, allow you to even snoop data, but still makes the smart card mostly useless outside the device. The reason being is Atmel smart cards use a challenge responce authentication protocol.

    Without getting into (unfortunetly I did sign a NDA at one point) I will tell you that it is good enough that just being able to snoop data isn't going to help you authenticate the card. They also have nice features that lock the cards after a certain amount of failed attempts and whatnot.

    That along with a little data encryption using whatever your favorite algorithm for security is and I would still feel confident in the security behind smart cards.

    Basically, Atmel leaves it up to the developer to decide how secure the cards are, but if you enable all there security features, and use a little common sense you will be fine.

    What I don't understand is why they can't just post the authentication system specfics on there web site for everyone to see. Security by obscurity isn't neccesary here as the algorithm itself wouldn't help anyone anyway.

  6. Re:533 Mhz?! on Intel Moves To 533MHz FSB · · Score: 2, Informative

    Ya, it is a little miss leading, but effectively it is kinda true. Since it pushes 4 things at once at 133Mhz. it is the same as doing one thing at 533Mhz. Same as AMD pushing two things at once doing 133Mhz is the same as doing 1 thing at 266Mhz.

    In a way I understand too, it is just easier to explain to the non-technical you are running at 266 instead of 133 or 533 instead of 400 or whatever the case may be then it is to explain that you are using both edges of the clock or using such and such method to get 4 times as much through the bus at one time thus creating this thing, that while it runs no faster in Mhz. then before, preforms x times faster.

    I mean, Mac tried to tell people there PPC's were faster then Pentiums for years any many wouldn't buy it because it was slower in Mhz. So you can see why they do what they do.

    Afterall, it isn't about the Mhz. that should matter to us that really know what is going on, what matters is the increase in memory bandwidth. And that is a very real increase. As it was when AMD went to DDR.

  7. Neither are prefect. on IDE, SCSI And Recording Everything · · Score: 2, Insightful

    IDE has gotten a lot faster these days but there are still many flaws.

    For one, most of the ATA133/ATA100 is a lot of hype. On long transphers (or any transphers that exceed the cache size of the drive) I have yet to see an IDE drive break 30-40 MB/s. In fact, testing an "ATA133" drive on an ATA133 controller vs. an ATA100 controller I saw no gain in speed. There was a gain from ATA66 because the ATA66 bus can't quite sustain 30-40MB/s constant.

    Which brings me to another point, like all buses, the 66/100/133 is the peak allowed, it is usually not nearly that fast.

    The drive speeds could be higher on IDE. You can get some top notch SCSI drives that run at 15,000 rpm. The best you find with IDE is 7200rpm. The drives would obviously be a little better at filling the bus if they had faster motors.

    The IDE bus lacks any intelligence. It is the intelligence you are really paying for on SCSI. The command queues, multitasking bus, ect. ect.

    Lastly, SCSI drives are obviously way more expensive, as are there controllers. Of course you are getting a higher quality (read=better built, not faster) product.

    Basically what it comes down to in real world performance is no matter what you choise, IDE or SCSI, your disk drives will be the biggest bottleneck in your system by a long shot. If you run a single drive system, or have enough buses so you don't share them SCSI doesn't really provide enough to justify the cost on a desktop in my opinion.

  8. A couple of rules on Alternatives to the CBDTPA? · · Score: 1

    I don't claim to have the answer on how to stop piracy. I also don't believe legislation is even neccesary here.

    However, there are a number of rules that must be followed in any legislation made to stop piracy.

    1. It can't limit free or open source software in any way shape or form.

    2. Reverse engineering must be allowed in all ways, shapes, and forms. I am not saying I should be able to rip off your source code and copy it but I should beable to reverse engineer your stuff so I can re-impliment it my way and get the same results. This is extremely important for competition.

    3. Copy protection schemes cannot be made such that they break a legal use of a material. For instance, if I buy a CD I have a right to turn it into MP3's and play it on my computer or other digital device.

    If the RIAA wants to sell more music they are going about it the wrong way. It has already been proven that MP3's have not decreased the sales of CDs. I for one download a good bit of MP3's to try out songs. Partially because I am sitting at a computer all day a work, and partially because the radio stations around here play nothing but the same old shit all day long. However, when I find myself listening to the same MP3 frequently I buy the CD. This is the way most people I know use MP3's and if anything it helps the RIAA. Those people that horde MP3's any never pay for the music aren't going to buy CD's even if they can't get there MP3's anymore so going after them is a lost cause.

    The fact is Movies, Music, and software industries bring home a lot of cash. Per employee they all bring home more then most other industries. When a company of 30,000 employees bitches while generating more revenue then a company that has 300,000 employees you won't see me feeling sorry for them. Especially since they have more actually money in the bank then most companies that size can even dream of.

    You also won't see me feeling sorry for a company thats sole purpose is to make money off the achievements of others while doing very little work themselves.

There is no way to prove it because there is no signature involved, and no witness required.

    I am pretty possitive you would get nothing if you took a user to court over the EULA. If MS thought that was enough they wouldn't have bothered with all the other shit like activation codes and the like.

    In my mind EULA's are a lot like disclaimers, and we all know just because you put "Using this might kill you" doens't stop you from getting screwed when somebody does exactly that.

    I don't think they can even get legal evidence you accepted the EULA without proving first you are running there products, which they can't prove unless they look at your machine, which they have no right to do unless you have accepted there EULA. Keep in mind the EULA isn't something accepted at time of purchase, it is something accepted at time of use.

    I am a junior/3rd year student at Georgia Tech. I took both of those classes back in my freshmen year. Cheat finder exsisted back in those days as well, but it seams they have changed there algorithms because a lot less people were labeled cheaters in the past.

    One problem I have is there definition of cheating not only includes copying the work of others but mearly discussing the projects in any way, shape, or form with a fellow student. At least that is what I was told specifically by a TA back when I took the class. Copying work is most certainly cheating. However, in college other students are great tools to learn from and there is no reason why discussing strategies for solving a problem shouldn't be allowed. I believe we like to call that cooperative learning? I remember reading some studies about how well that worked in a psych class I took at Tech....

    The other problem is the simple nature of the problems could cause many students to use similar methods that could be picked up by cheat finder. I happen to know a freshmen who struggled greatly in the class and came to me for help on many occassions. This particular student never discussed the projects with any other people in the class, and never shared code, but was picked up for cheating because there were trends in his code that matched other students. I realize that by the strict and stupid nature of there defition of cheating he couldn't even ask me about solving some of his problems (I didn't write any code for him, just gave him so ideas how do to certain things since he had never coded before) but the fact is he now knows the material and deserves to get the B his grades earned him and not an F for all the time in effort he put into learning it.

    The CS department needs to focus more on teaching there students rather then catching them for cheating. Maybe if they focused there effort on creating a class that better taught the material less students wouldn't feel the need to use the students which already know the material as a crutch to make it through. Especially in a class required by all majors.
