  1. Re:Up front on 34 Design Flaws in 20 Days of Intel Core Duo · · Score: 1

    Yeah, not checking your design before you release it and then make the errata available immediatly is actually much better than not checking at all - NOT!

    So, are you saying that you can check every single path in a CPU and judge them all to be completely correct? The design is very much like software in that you define a finite set of use cases and test them. You're bound to miss some things.

  2. Call me crazy... on Saving Energy in Small Office Buildings · · Score: 1

    Call me crazy, but when the link is for "a control algorithm," I expect the link to actually point to the algorithm and NOT to an article talking about it. Both are useful, but please label links correctly.

  3. Re:Are you sure your power is all the way recovere on PC Not Booting Until a Different Phase is Used? · · Score: 2, Informative

    If you have 220 in the house (typically for an electric stove or a clothes dryer), you have two phase coming in from the street.

    Not really. House 240V power is created by connecting one phase of a three phase feed to a transformer with a center tapped output. The center tap is grounded and voila, you get split phase 240V power. It consists of a ground, plus one leg at +120V and the other at -120V, referenced to ground of course. Take the potential across the two of them and you get 240V. While these legs are separated in phase by Pi radians, this is not what is referred to as two phase power.

  4. Re:ALL devices and connections to the same ground on PC Not Booting Until a Different Phase is Used? · · Score: 1

    Not sure if you realize this, but Ethernet over copper is not referenced to ground. Look on any NIC, the RJ-45 jack is connected to an isolation transformer. I'm not saying establishing common ground is not a good thing to do, I'm just pointing out something you may not have been aware of.

  5. Experimental Error? on Ars Technica Reviews Intel iMacs · · Score: 2, Insightful

    I get so annoyed everytime someone supposedly benchmarks something on a PC and includes no experimental error figures, no mean, no standard deviation. Maybe that's because when you only test things once, the sample standard deviation is infinite! Doing this in an engineering or scientific paper would get you laughed out of the journal or conference. Reading the following in the Ars discussion forum just reinforced my thoughts:

    XBench is not great for benchmarking unless you repeat it's tests about 10 times or more each... its results vary too much (even from one run to another on the same machine, never mind when comparing two different ones).

    Come on people, do many tests, compute the data, adjust with Student's t-distribution. This is elementary stuff yet no one does it.

    No depth-of-focus preview button in the lower-priced digital SLR bodies.

    My 350D has depth of field preview. I wouldn't have bought it if it didn't. The modifier button for exposure compensation is close enough that I can hit it easily while turning the dial. Another wheel would be nice, but not worth the extra money for a camera that has one. Oh, and I got my 350D body for $599 new, from Dell (not some shady dealer).

    I have the same card. No problems. I bought it because it has dual DVI outputs. Eventually I'll get another Dell 2005FPW so I can make use of that functionality ;-)

    The heat equation is beautiful, as it applies to so many different things (heat, diffusion, options pricing).

    That's the Laplace operator, in case you couldn't tell.

    I have this problem on *every* platform I use Thunderbird on: OS X, Linux, and Windows. I can't figure it out for the life of me. The only way to make it notice the messages is to restart it. It's most annoying when nothing tips you off that you might have messages and you just asusme you actually don't. I'm convinced all IMAP clients are horrible.

  21. Re:ugh on Have Geeks Gone Mainstream? · · Score: 2, Informative

    Is it that you can't do math or you won't? If you can't, that's one thing. If you won't, sounds like you're just not trying. CS Bachelor's programs really don't require a lot of math. Typically it's two semesters of [very manageable] calculus, a semester of basic linear algebra, and potentially some numerical analysis. If you otherwise like the curriculum, it might be worth getting through that to stay in it.

    I suppose I should throw a caveat in here that I'm an engineering and mathematics double major so I'm a bit biased in my suggestions.

    And that accomplishes nothing. It's just like taking guns away from people who want to own them legally. People who read that sign and abide me it, much like people who properly purchase firearms, are not the ones you need to worry about. Frankly, I don't even know what an "administrative PC" is anyway. My laptop can be an administrative device wherever I take it. This is why you use things like one time passwords and carefully protected SSH keys for security.

  23. Re:textbooks on Amazon to Sell Books by Page, Display Books You Own · · Score: 1

    It's not the professors. They're just as hamstrung as the students. The publishers keep rolling out new versions and you cannot buy new the old versions, so they cannot list the "out of print" edition as being the official text book. What I do appreciate, though, is when professors make their own problem sets or scan to PDF the problems from the book. That way, if I buy an older edition to save money, I at least have the right exercises, because that's often the only (if any) thing that changes from one edition to the next.

  24. Re:I agree on Online vs. Traditional Degrees? · · Score: 2, Interesting

    As this implies, math is not science either.

    "Mathematics is an experimental science, and definitions do not come first, but later on." - Oliver Heaviside. Now, you might argue that Heaviside didn't have much authority to say that as he wasn't a "true" mathematician and he pissed off the academic community at the time* but I find it a bit of a stretch to claim mathematics cannot be called a science, be it by denotation or connotation.

    * While working on using Laplace transforms for all sorts of nifty things, Heaviside neglected to rigorously prove certain details. Such circumstances are what led him to make the above statement. For example, if you work out the derivation of the Laplace transform of t^n*f(t), it necessitates swapping an integral and derivative. For "nice" functions, this works, but it does not always hold true. You can imagine that leaving out a proof of when or when not this holds could have annoyed certain people.
