Nyquist's theorem states that you can accurately represent frequencies up to 1/2 the sampling rate
The nyquist theoorum says nothing about accuracy. It says that it is impossible to represent frequencies above 1/2 the sampling rate. The higher the frequency the more aliasing. At 44k samples per second a 15 kHz tone has three samples per wavecrest, so you can't tell what the shape of the wave is at all.

In 1978 I had an absolutely KILLER stereo. The turntable was a German made Dual with the tonearm suspended on a four point gimble, and the speakers included six drivers each, including fifteen inch woofers (and you kids have "super" woofers at five inches. Bah) and "super-tweeters" for tones above 15kHz.
If you cranked Van Halen's first album up to nine and closed your eyes, Van Halen was in the living room. When we moved in 1979 the new neighbors saw us moving in, we moved the guitars and such in last, opened a bottle of tequila and cranked Van Halen's only album.
The next day we met the neighbors. "Wow, man, your band kicks ass!"
I have yet to hear a CD that anyone would confuse with a real live performance. CDs are not high fidelity. A blind man can throw all the mathematical proofs at me all he wants but he's still not going to convince me that the color red doesn't exist.
The Nyquist limit says nothing about the shape of the waveform, and if you think about it is just common sense - at the nyquist limit there is less than one sample per crest, so if you didn't filter out all frequencies above the limit you would get very audible nastiness.
A 15kHz tone has three samples per wavecrest. With only three samples there's no possible way to differentiate a square wave from a sine wave from a sawtooth wave. With digitally sampled sound, the higher the frequency the more aliasing.
And although your ear can't hear the tones above CD's nyquist limit of 22kHz, those tones color the frequencies you can hear.
I see MP3s and other lossless codecs as something transient, an equivalent of cassette tapes - all right to listen to, but you wouldn't want to keep them forever
I beg to differ. I have tapes that are older than many slashdot readers, dating back to at least 1970. Many of them I've replaced the housing on, as the rollers jammed or the lubrication sheet wore out. Some have been "eaten" leaving flutter in spots, some have been spliced leaving a skip, but some sound so good that when I've sampled them to CD people can't believe that they were originally cassette.
With analog, your gear matters greatly. My car is an '02 with a disk changer and cassette. A home burned CD of a cassette actually sounds better than the cassette it was sampled from in the car!
There is a tiny audible difference between most factory stamped CDs and their cassette counterparts, but on some analog-recorded ones the cassette CD sounds better than the factory CD due to bad digital remixing from the studios.
Cassettes recorded and played on good equipment are vastly superior to MP3s at any bitrate and come pretty close to CD.
Odd, but a dog-eared thirty year old paperback copy of Return of the King is on my desk in front of me (44th printing, March 1974), and there is a photo of Tolkien on the back with the caption "This paperback edition, and no other, has been published with my consent and co-operation. Those who approve of courtesy (at least) to living authors will purchase it, and no other." -J.R.R.Tolkien
The emphasis is mine. I realize that Tolkien was British, but here in the US copyright is supposed to exist in order that authors will bring new works into the world that will later fall into the public domain. I see no way for Mr. Tolkien to write any more books; in this world, at least.
I also see no reason why a completely new work should be covered by copyright of an existing work unless it lifted parts of the old book, but of course IANAL (thank God).
"He would have finished him off then and there, but pity stayed his hand. It's a pity I've run out of bullets, he thought, as he went back up the tunnel..."
My favorite characters of course were Frito and Dildo Buggers.
... they might as well have the soundtrack performed by Led Zeppelin.
You mean like
The pain of war cannot exceed the woe of aftermath, The drums will shake the castle wall, the ring wraiths ride in black, Ride on.
Sing as you raise your bow, shoot straighter than before. No comfort has the fire at night that lights the face so cold.
Oh dance in the dark of night, Sing to the morning light. The magic runes are writ in gold to bring the balance back. Bring it back.
At last the sun is shining, The clouds of blue roll by, With flames from the dragon of darkness, the sunlight blinds his eyes.
or how about
Mine's a tale that can't be told, my freedom I hold dear. How years ago in days of old, when magic filled the air. T'was in the darkest depths of Mordor, I met a girl so fair. But Gollum, and the evil one crept up and slipped away with her, her, her....yeah.
Seeing how Hollywood treats most novels, I was actually pleased with LOTR; far more than with Hitchhiker's Guide, and that one the book's author actually worked on (until he died anyway). I mean, Marvin didn't complain about the pain down the diodes in his left leg even once, and he ddn't kill any police cruisers by depressing them to th epoint of suicide.
Don't get me started on I Robot. Somebody needs to go to prison for murdering that book.
I saw the actual screenplay. Elrond is reincarnated as a computer virus that infects the Shire by turning everyone into copies of himself before Frodo lets himself be killed.
Peter Jackson did a great job in visualizing and bringing to life a story in which the plot was already fully written
I agree. I hadn't (re)read the books in over a decade, maybe two, but I'm a hyperlex; when I read I'm there. And all the characters looked and acted like what I'd remembered them being in the books.
Of course I (re) read the books (again) after seeing the movies and yes, there were some differences, but far less than one would expect given Hollywood's history of bad movies ruining great books.
You're happy? YOU'RE happy? I read the Hobbit in 1970, do you know how fucking long I've been waiting to see this movie?
Do you know how damned disappointed I was with I, Robot? Global warming is caused by the friction heat of Asimov spinning in his grave.
I was less disappointed in The HitchHiker's Guide to the Galaxy but still disappointed that the scene where the police cruiser commited suicide after talking to Marvin wasn't there; in fact the cops never showed up at all.
Do androids dream of electric sheep? If an android has a wet dream, does he short out?
This seems like the grownup, nerdy version of "What if every time I leave the room it blinks out of existence?"
When I was a teenager working at a drive in theater, there was a college kid taking a course in philosopy working there who believed this. After successfully arguing with him, he turned his back and said "you no longer exist."
So I threw a dirty wet rag and hit him square upside the head with it. End of conversation!
I agree, except that there need be no conflict, no "which camp do you belong in?" Science and spirituality are not mutually exclusive. There are no "camps" save for example Baptist vs Hindu, or Big Bang vs oscillating.
"But officer, I wasn't doing anywhere near 299,792,458 miles per second!"
Slashdot Mirror
I suspect you're right.
They don't function at all in Linux. In Windows I use about all the controls as I've usually got the monotor shut off.
Personally I enjoyed the joke. But I save spell checking for things that are a bit more important than a slkashdot comment.
And oddly, although I don;t worrry about karma and often get modded troll or flamebait my karma remains excellent. I have no idea why.
See what happens when you don't have anough coffee?

"What do you think I am?"
