  1. Re:Have they added DRM yet? on Vinyl Record Production Gets a Much-Needed Tech Upgrade (engadget.com) · · Score: 1

    Two kinds of oversampling:

    You're probably referring to upsampling upon playback (reconstruction). It is a "fix" in the sense that it obfuscates, it is not error correction. This only reinforces my point, which was that it is not impossible - or even implausible - that a human could distinguish in a blind test a recording made at a higher sampling frequency (than 44.1) compared to an identical one at CD quality.

    If you're referring to sampling at a higher rate than the Nyquist frequency at recording, the reason that's done is because you can hear the difference if it isn't recorded at a higher rate. The big difference here is that post-processing allows storage of the smaller amount of information (frequency and bit rate) of the target. I'm simplifying a bit here, but that's actually my point: you can hear the difference.

    Perhaps you're solely focused on playback frequency in the discussion? I'm not. I'm suggesting that, at any point in the chain, if you operate solely at 44.1kHz sampling rate, you will lose something, in spite of the fact that human hearing tops out at about 20kHz.

    Cheers!

  3. Re:Have they added DRM yet? on Vinyl Record Production Gets a Much-Needed Tech Upgrade (engadget.com) · · Score: 1

    But we're talking about CD sampling/recording rates, not turntables here.

    The original frequencies aren't necessarily below the noise floor of the recording process, and can introduce harmonics during the playback process. Many do have enough "energy"; there's no magical cutoff at 20kHz just because that's pretty much the upper range of human hearing.

    You can argue - somewhat correctly - that those harmonics within audio range would be captured by the lower (CD-quality) sampling rate.. but herein lies one of the things that, depending upon conditions, can be heard. It's not the same sound profile as playing back the actual higher frequencies because (shockingly enough) playback conditions impact how it sounds. Note I'm not saying one would sound better than the other, just noticeably different.

    Also, if you have inferior AD conversion and low-pass filters when recording, anti-aliasing can be a problem caused by higher frequencies. Again, I'm talking strictly about higher sampler rates and storage at "better than we can hear" quality. AC (not sure if it was you) argued it was completely identical under all cases unless you were some kind of mutant. That just isn't true. It's mostly true, but not completely.

    Finally, if we were to do what you suggest with a vinyl record, it... doesn't prove much of anything. Why? You're only passing the higher frequencies. The harmonics occur at a lower frequency in terms of the music. Ostensibly, you're playing inaudible frequencies against line noise, which will of course sound like line noise. This, of course, assumes that the recording wasn't at some point or another passed through some kind of EQ or digital recording (same sample rate discussion) that didn't remove them. Digital recording goes back much further than most people think..

    Emphasis here on something that is mostly irrelevant: the difference between OP saying it's impossible for there to be any distinguishing characteristic for humans, and then talking about what the practical implications are. You really should read the short article I linked, it gives a fair, if high-level, explanation.

  4. Re:Have they added DRM yet? on Vinyl Record Production Gets a Much-Needed Tech Upgrade (engadget.com) · · Score: 1

    I'll disagree with you ... mildly... about the CD versus higher resolution. It's about harmonics introduced by higher frequencies impacting the lower (and the reproduction of said harmonics during D/A conversion upon playback), and anti-aliasing of higher frequencies unable to be captured correctly (a la Nyquist). Does it mean higher frequency is better? Sometimes yes, sometimes no. A lot depends upon not only exactly what is being recorded, but the equipment and conditions for both recording and playback.

    I'll agree it's mostly hype for little or no benefit, but it isn't entirely fiction.

    There's a lot of truth in this, and in visuals anyway. Case from my own experience:

This system was geographically situated in a such a way that different locations were located on a map. The top-level view of the system might refer to different geographic locations (e.g. "First St node" and "Highway 3 node").

    This was during the time that Google Earth was New! Exciting! AJAX?! For a prototype, we lifted *the customer's own marketing map graphic* and overlaid a colored disk at each location representing current status.

    Two side effects of the prototype demo: first, the sheer wonderment of "how did you get that?! Is it a satellite?! IS IT GOOGLE EARTH?!" Second: "How does it know the status?" "Holy crap! Maple Ave node IS RED ZOMG CALL SOMEONE WHAT DOES IT MEAN?!"

  6. Happened to Me in Brisbane on 70 Laptops Got Left Behind At An Airport Security Checkpoint In One Month (bravotv.com) · · Score: 1

    The guy found it, then explained the problem was that it hadn't been through customs. I had a co-worker coming through the same flight in a couple of days; he agreed to give it to the co-worker. I figured that this was unlikely to actually occur, and started backup planning.

Further, it's typical with such places to have a minimum time in service (12 or 18 months, usually) before being allowed to move to a new position... because lots of qualified people are sticking their foot in the same door.

    Before I went back to school and got my CS degree, I worked customer service at a major wireless carrier. At the time (mid/late nineties) they were expanding and growing. I had a friend who worked customer service there (because she wanted to get into sales, and they said 'you will need to get your foot in the door') and said if you can do your year, within six months afterward if you have any skill whatsoever you'd find a different job. She did; I did; it all worked out. We knew what we were getting into and, yes, a year on the phones kinda sucked. I had my eye on a larger prize and knew my own skills, so it worked for me.

    I've seen it time and again: the overwhelming majority of people need leadership. What kind of leadership is specific to the individual; good mgmt can tailor their style to individual needs. Rare - much rarer than most people think - is someone who needs no leadership.

People slack off; some people work in chunks (as I do - I will goof off for a couple of hours and then pound out a day's work), some people work slow and steady.

    Marriage has not been defined as that for "thousands of years". It's actually varied quite a bit from culture to culture and over the decades, and even in modern times. Even Wikipedia has multiple well-referenced examples. Miscegeny was NOT legal, socially acceptable, or the norm in the overwhelming majority of cultures - even Westernized ones - until relatively recent history. I'm old enough to remember when seeing a black man holding a white girl's hand, walking down the street in the major city I grew up in, drew openly hostile remarks. I'm not that old, either.

    Saying there isn't anything discriminatory in a definition - and that it's based primarily on biology - is specious. Couples who can't or don't want to have children get married. For a long time published arguments against miscegeny touted the idea of racial dilution and even health hazards to any babies.

    You may understand why people don't want to change it. So do I: they're bigots.

Anyone who thinks they can be anti-gay marriage and not have a very narrow, judgmental, bigoted view is deceiving themselves by couching their bigotry in supposedly sound arguments of culture, society, and biology. That fits your Webster's definition quite soundly. I'll agree my stance does too - however; the same argument can be positioned for any stance (again - substitute interracial marriage and the people against it).
