    Put your little fist of death back in your pocket. Fine, I shouldn't have picked a 20 kHz square wave. What about an 8 kHz square wave? First harmonic: 8 kHz. Second harmonic: 24 kHz which is above the nyqust frequency. I can hear 24 kHz and from playing with a signal generator I know I can hear the difference between a 8 kHz square wave and an 8 kHz sine wave.

  6. Re:AAC is nice and all... on McDonald's Billion-Song iTunes Giveaway · · Score: 5, Informative

    A CD is lossy. Nyquist says that your sampling frequency has to be at least twice as high as the bandwidth of your signal. The lossiness comes in due to the band limiting that is done to avoid anti-aliasing. Any frequencies above 22 KHz are filtered out, so if the highest frequencies of your music are pure sinusoids then yes, it would be lossless, but if they're non-sinusoidal then you will have losses. Consider a 20 KHz square wave. It's below the 22 KHz cutoff so it will be duplicated perfectly, correct? Nope. The 20 KHz square wave is made up of higher frequency sinusoidal waves: 20 KHz sine wave, 60 KHz sine wave, 100 KHz sine wave and so on. Your 20 KHz square wave will be reproduced as a 20 KHz sine wave instead.

    You're also lossy because the amplitude of your signal is discrete. The voltage of your waveform can't take on any voltage, only one of 2^16th (from memory) discrete values. That's another form of signal loss.

    I still believe that a CD has higher fidelity sound than any vinyl I've heard. Maybe if you spend enough cash and get some very specialized equipment and special albums you'll have higher quality sound, but I'm not personally willing to spend that much money.

    Even in high school physical education hardly any time was spent on learning about caring for your body. You'd learn various sports, spend a bit of time learning to dance and a little bit of time learning how to not knock up a girl. No time that I can recall was spent on learning how to stretch or how to build a meal that has all the nutrients you need. I've learned a lot of these things on my own but most of the other engineers I work with never did and just bitch and moan that they're sore after 30 minutes of water skiing, don't have any energy while pounding a Big Mac, fries and a gallon of Coca-Cola into their mouths.

  9. Re:I love how they try to cast this as pro consume on Court Upholds FCC's 2007 Deadline For Digital TV · · Score: 1

    If you only use your TV for video games and DVDs then you're already paying for a tuner you don't use, and a decade or two ago it was an expensive part of the television. Consumer electronics always lower in cost towards nearly nothing, and right now it happens very quickly. The first CD player I bought cost about 1000 dollars (it was the first Sony, I purchased it in high school). By the time I was graduating from high school I could get a portable unit for about 150 bucks. Now a decade or so later you can get a portable unit for 10 bucks or a home unit for 30 or 50 bucks.

    So over only 4 years the price of a CD player dropped by almost an order of magnitude. Over 2 decades it dropped 2 orders of magnitude. I expect that early adopters for digital television will pay through the nose. Eventually the price will drop.

  10. Reintroduced copied Windows feature? on An 'Open Letter to Apple' · · Score: 5, Interesting

    I recall that this was available natively in MacOS 9 but then was dropped for X. So Proteron was more accurately copying a dropped MacOS 9 feature (which may have been copied from Windows) and now Apple's re-including it. I doubt that Apple looked at Proteron but do believe that Apple looked at Microsoft. I don't really see anything to get up in arms about here. Watson v.s. Sherlock was much more obviously a rip off of a 3rd party piece of sofware.

  12. Re:I, for one! on Wanted: a Real Science Channel · · Score: 1

    I don't really buy the argument that people are staying away from science and engineering because they won't find a job. I went through undergraduate electrical engineering. Out of graduating class of about 70 there were 8 north americans. Most of the rest were from Hong Kong. Those of us who wanted engineering positions have engineering positions.

    A lot of people got into engineering with this idea in the back of their mind that they expected they'd be able to walk into someplace and be an instant engineering manager. Well, this doesn't usually happen. You graduate from an engineering school and you know a shallow amount of information about a wide variety of engineering topics. There's nothing wrong with this, in fact I think it's great, but for an engineering manager they want somebody who has a deeper amount of information about a narrower variety of topics. There's nothing wrong with this either. After you spend a few years in the field working building on the basis you have in this narrower body of topics you can move into management if that's what you want and you have that talent.

    Now some people not only expect to start as managers but they're not willing to take a position as a lower ranked engineer in order to build experience. So later on they say things like there are no jobs, or an H1-B worker took all the positions.

    There are two seperate metrics that define the speed of memory. Latency, which is what your 40 ns refers to, and bandwidth. Large caches address the latency problem as you stated. If you want to transfer more bits per cycle you're restricted due to signal integrity issues related to the bus, so the parent post is also correct. You can increase the width of the bus, up to a point, and get a small scalar increase in bandwidth. To go beyond this you need to address signal integrity problems.


    Sending fast edges over a bus is difficult because the signal degrades:

    • inter-signal interference: Each parsel of information spreads due to the RC nature of the bus so that it takes up more than a period, thus interfering with the next packet.
    • cross-talk: Each wire on the bus is fairly tightly coupled with it's neighbours, so switching activity on one wire affects it's neighbours.
    • transmission line effects: Package connectors, bends in circuit traces etc all create impedance mismatches. This causes reflections which degrade the signal.


    If your dataset fits into the cache well, which is often the case for PCs, then a cache can fix most of your problems. If you're dealing with datasets that span gigabytes or terabytes and your application can't be subdivided such that processing and memory can be constrained per cpu then your cache doesn't assist you very much.

    Are you late even at 7:31? One minute past? YES! Your employers set up the rules, as a good employee you should respect an abide by those rules.

    Yes, you are late if you arrive at 7:31 instead of 7:30. In some cases this may be a real problem, i.e., if you're in a situation where there has to a person covering a help desk or phone. In most cases it isn't an issue however. If management is going to be this facist about being a minute late then they had better expect that I will be equally consciencious about their side of the contract when they expect me to work extra hours (possibly for free if you're salaried) because they were incapable of creating a realistic schedule for a project.


    Fortunately I don't work at a company like that. I usually arrive at work at about 6:30 am, most other people come in at around 9:00 and some as late as 10. Occasionaly I need to modify my schedule to allow for a meeting to take place and I don't have a problem with that. If they were to start moaning about the hour I come in at I would gladly move my start time. I would also push back and just do an 8 and skate. If management gets facist on me I'll pretend I'm a unionized employer and only do what's required by my contract or that which I see has a high probability of getting pay increases or bonuses.

    With software you're assumed guilty unless you can provide the license, especially with the BSA relying on your inability to afford to fight them in court. I've got a PC running Windows 2000 in my office. I haven't turned it on in over a year and while I am completely legitimate I will be damned if I could find my license or original install CD. That doesn't make me guilty of piracy, just bad house keeping. Yet if the BSA were to decide to come after me I would have to pay up because the cost of proving my compliance in court is greater than the cost of just shelling out cash.


    It's Microsoft's responsibility to prove that you're not licensed, not your responsibility to prove that you are. It's part of that old innocent until proven guilty and all. To do this Microsoft would have to be even more draconian than they are now about registering software. The software doesn't run until it's registered, even if that means a non-internet connected customer has to wait for a license key in the mail.


    Of course this would probably turn more people away from Microsoft, but that's not my problem.
