  1. Re:The keys to the kingdom on Linux in a Business - Got Root? · · Score: 1

    Let's hope he never gets sick, eh?

  2. Re:MIDI is akin to printed music on The Place Of Modern MIDI Music? · · Score: 1

    I have several "Fake Book" volumes and these appear to be legitimate. However, the Real Book series are the de-facto series that most jazz and popular musicians use on both sides of the Atlantic, mainly because the chord changes are by gigging musicians and not a publishing office. They are usually photocopied and handwritten. I believe there are 5 volumes of the main real book series, along with various others for latin etc. I've heard they are all available on a CD now too. There is now a legal series called "The New Real Book" which also has around 5 volumes, but slightly different songs and arrangements in each volume. They can be purchased in most good music stores.

  3. WoW on Sony Pulls Controversial Anti-Piracy Software · · Score: 1

    Hasn't this whole thing caused a massive outbreak in World of Warcraft cheating though? Could Blizzard sue Sony (or is that dangerous given the state of their big brother antics?)

  4. Re:Microphones and Speakers on World's Most Powerful Subwoofer · · Score: 1

    It can be shown (hell, you can do it yourself with graph paper and drawing a sine wave) that sampling at 44.1KHz will not come anywhere close to accurately representing all frequencies below half of that frequency, and it isn't until you reach a much lower threshold that you get close.

    There are some frequencies that will only have the rising half of the signal captured, others which might only get every other cycle (effectively halving the recorded frequency).

    If you think of a 20KHz sample rate with a 10KHz sine wave you could capture the peaks. Or you might capture the zero crossings, or somewhere in between depending on the phase. So I might have anything from 0 to 100% of that frequency present when I replay. If you go to a 7.5KHz sine wave things get even more complicated. It isn't until you drop to something like 1/10th of the sample rate you start to get reasonably accurate results.

    Can the ear hear it? Who knows. Many people can hear a difference on high end equipment between 44.1KHz and 192KHz recordings (of complex material, eg orchestral music in a concert hall captured using a Nimbus-Halliday or Soundfield type microphone array).

    Sure, you can remove the harmonics caused by aliasing, but that's not going to put back what wasn't captured.

  5. Re:Microphones and Speakers on World's Most Powerful Subwoofer · · Score: 1

    Well, Nyquist states that the *minimum* sample rate to capture a band limited signal is *at least* twice the highest frequency. At least. Sampling a 12KHz sine wave at 44.1KHz produces quite a nasty waveform with a lot of harmonics due to aliasing. Imagine what happens to a 19KHz signal.

    Add that to cross modulation effects of similar frequencies (producing both lower and higher frequency components themselves) and you have a right mess. The ear might not be able to hear many frequencies above 10-20KHz, but you can hear the cross modulation effects quite clearly - another reason that a 44.1KHz sample rate isn't anywhere near high enough for truely realistic reproduction. IMO it's good enough for the majority of music released today, especially given the insane amounts of compression and processing done to signals, but quite poor for orchestral or other acoustic recordings.

  6. Re:So tell me, do I have this correct? on Open Source Code Finds Way into Microsoft Release · · Score: 1

    Microsoft calls OSS viral.

    I thought they called the GPL viral (which is a perfectly valid description). Open Source is not just the GPL, and existed long before the GPL. They then pursue obtaining anti-virus software... Now this.... Does this mean Microsofts anti-virus software ain't worth a crap, or does it mean the problem is in a faulty (lacking integrity) mindset at MS? Or both?

    Was this meant to be funny? "Viral" applied to licences as against malware means something quite different..

  7. Re:USB car stereo on VW Goes USB · · Score: 1

    My bad, I missed the post about the FM transmitter.. oops!

  8. Re:USB car stereo on VW Goes USB · · Score: 1

    Why are they illegal to use? (I'm in the UK and I can't see anything from the description that makes them illegal...)

  9. Re:Nothing new... on VW Goes USB · · Score: 1

    Yeah you can connect your iPod to one, but you would not want to. Just like you wouldn't want to connect up a large hard drive or memory card. The user interface on these cheap head units (particularly the models you mention) is awful - you have to find tracks by file number, not by album / artist etc, and have to jump through either 1 or 10 at a time.

  10. Re:Who is paying double, let alone 4x? on Europe Plans a New Type of Fusion Facility · · Score: 1

    It is a little under $5.00/gal here in Kyoto, Japan, and this is one of the most expensive places in the world.

    Rubbish. Here in the UK it works out to around $6.50 a gallon from the cheaper places, and anything up to $8 for some of the smaller garages in hard-to-reach- places (or commercially exploitable). We aren't the most expensive in Europe either. Of course, most of that is tax though - I love being in rip-off Britain!

  11. Re:x86 on Mac OS X on x86 Videos Get Apple's Attention · · Score: 1

    Well done! :-) (is that a penny I hear dropping?)

  12. Re:Key + Lock on Mac OS X Running on Non-Apple Hardware · · Score: 1

    What does his UID have to do with anything? I've been reading Slashdot since sometime in 1998, but only registered today. Does the fact that I have a high UID make me a n00b or something?
