  1. Re:What's an FFT on High performance FFT on GPUs · · Score: 1

    eh, not really.

    Wavelets provide time AND frequency resolution; FFT is ambiguous to time. The closest Fourier variant that I'd say remotely compares to a wavelet transform, would probably be the STFT. ...though the STFT's harsh windowing has the ability to introduce quite a bit of high-frequency noise. While wavelets are often used to de-noise a given signal.

    But on the topic of compression, the JPEG2000 standard uses wavelets.

  4. Re:sample interview questions? on Starting a Home-Based Software Company? · · Score: 1
    Does it matter if they know how many bits are in a byte if they're coding applications (eg payroll, finance, hr) on windows with VB or MS Access etc? ... or does this only matter if they're coding with C and variants ... So my answer would usually be "I forget" most of what was in my CS program.

    If your CS program had a decent assembly, digital logic or low level algorithms class, you'd realize that there are plenty of cool bitwise algorithms that are extremely fast when compared to the generic library routines.

    For example:

    Take a look at this portion of a decision maker function, which maps several form checkboxes into a single number:
    var combo = form.elements[0].checked*(Math.pow(2,2))
    + form.elements[1].checked*(Math.pow(2,1))
    + form.elements[2].checked*(Math.pow(2,0));
    The following code uses bitwise operators to do the same thing as the code above, but much more efficiently:
    var combo = form.elements[0].checked << 2
    | form.elements[1].checked << 1
    | form.elements[2].checked << 0
    Granted, if you're developing in VB or Access, speed and efficiency is probably not the top concearn... but if it was and you'd like to use a speedy replacement, it helps to know the characteristics of the data you're working with.

  6. eewww... Aperture grills on Shopping for a New Monitor? · · Score: 3, Informative

    Trinitrons use the horid aperture grill instead of a shadow mask. The aperture grill causes the annoying lines that we just love to hate.

    Here's the quick breakdown:

    Shadow mask: The shadow mask in a CRT monitor is a metal screen filled with holes that sits just behind the phosphor layer. Red, green and blue electron guns each send a beam through a hole in the shadow mask to a single pixel triad of the tube's phosphor layer. Although this method keeps the image sharp, it diminishes the potential brightness of the screen.

    Aperture grill: Instead of a metal screen, the aperture grill consists of tiny vertical wires. The pixels on the phosphor layer are arranged in vertical stripes instead of triangular groups. When the electron guns scan across a row, the wires isolate the pixels that the individual beams focus on. This approach has a couple of advantages over conventional shadow masking. First, the use of wires instead of a screen allows more of the energy from the electron gun through, which makes for a brighter image. Second, the potential vertical resolution of a display can be greater, since the aperture grill does not rely on the vertical spacing of pinholes as a shadow mask does.

  8. Re:You are very, very wrong. on Visiting the World, as a Geek? · · Score: 1
    I did pretty much everything in high school except music and drama, and I loved it.
    You are obviously in the group of people that would fall in the exception category. But you cannot argue the fact that there were a definable group of individuals that were overachievers just to fill their college applications(at least in my school there was).
    Now, don't get me wrong, I spent my fair share of time in front of the computer too, but if oyu'er not doing sports, or part of student council, or on the debate team - what are you doing with your free time? Drinking?
    There are a plethora of activities outside of the high schools. I for one was really into church functions, a software upstart that I worked in conjunction with my other friends, and my heavy metal band. Not to mention that starting the second half of my junior year, I began taking night classes at the local university to start my college education. There's nothing wrong with people who decide to take advantage of everything their high school has to offer. But, I believe there is more happening off their campus than most kids realize... I'm glad I took the time to look beyond.

    You seem to be missing the point. Not all gambling sites charge a "cash out" fee (I'm not going to mention one because this is not an advertisement), thus, as long as you are able to avoid the temptation to "roll the dice" from the point when you transfer the funds to your gambling account to the time you cash out your "credit"... you shouldn't lose anything.

    Some gambling sites have a surcharge, but most that due (that I've seen) are lower than PayPal's fees. ;)

    The point that it is a browser is irrelevant. The prosecution is attempting to point out that Microsoft has been anti-competitive in the past, and may still be running this type of business.

    In this day and age, most people have somewhat of a grasp of what a "browser" is and it's use. The quickest way the prosecution could fsck this case is if they decide to saturate the courtroom with abstract technological jargon. I believe the browser issue was a good tactic to implement.

    ...so... how can you make people with this type of outlook, your excuse in losing the battle over the desktop?

    I think it is evident from looking at the average hardcore gamer that uses Windows primarily.

    IMHO I believe that they would be the easiest "Microsoft using demographic" to sway to Linux. Taking into consideration that (most of) these hardcore gamers already have a basic understanding of hardware, drivers, etc...

    When it comes down to it, they are gamers. If gamers were flocking to Linux, I don't believe that Loki would have went under since they were the largest single business entity involved in Linux gaming.

    NOTE... Of course it is possible that Loki went under due to other factors than just slow sales, but having an almost non-existant customer base is the most obvious.

  18. Television Subscription service? or Spam service? on Trimming Television to Sell More Ads · · Score: 2, Interesting

    But wait, with this service it is atleast 1/3 unsolicited forced "spam!"

    I understand commercials are a necessary evil that we have become acoustomed to, but why can't I have the option to pay a little bit extra for no commercials. Here's how I think the ideal situation would work...

    Most television programs are filmed where approx. ten minutes of every thirty minutes are for commercial sponsors. Why not play the programs back to back, and be able to broadcast three episodes in the place of two episodes with commercials. Hopefully the concept would catch the attention of the masses and have a wide subscription clientele to make up the lost revenue brought in from commercials.

    I realize that there wouldn't be much incentive for any parties other than the consumer, but I can dream - can't I?

    It would be my luck that I would be transfering the last 10megs of a 500meg cd-image, right when my IP changed.

    But seriously... It sounds good in theory, but if developers don't code their apps for the instantaneous IP change, it could seriously cause major headaches.

    Also there would need to be downtime for an IP before it was used again, otherwise I could make a request, (then if hypothetically I changed IPs, and my old one was assigned immediately) the other user with my old IP would recieve the packets. Which could be a huge security risk, if transfering sensitive material.
