There is this sort of undercurrent in a lot of Microsoft literature on MSDN, Channel9 and other sources (see this in particular); many units in MS seem to take it for granted that "computing" is essentially an activity of programmers, and that end users need not be bothered with it. Sure, end users use computers, but really all they do with them is stuff they could've done without them, just faster (according to MS).
Since an operating system is a "computing" product par excellence and really has no relation to a practical end-user process (by their reckoning), Microsoft only indifferently supports its operating system for end users, and primarily targets its attention on getting developers to make the switch. They believe, for good reason, that if they get the devs to build on Vista, then the end-users will just follow the applications, and that they won't really need to market the OS. Or, for that matter, even spend too much energy supporting it, since performance and reliability are always secondary to compatibility, which the developers lock the end users in to.
The samples in a CD PCM stream are signed, so (2^15)-1 is the correct value for the positive excursion of the waveform, though you've got another (2^15)-1 on the negative swing.
Remember that on the DVD you are getting the theatrical soundtrack
Little point: we usually remaster the soundtracks for home theater and that's what you get on a DVD. It's just the theatrical printmaster tweaked a little bit, while monitoring through a near-field 5.1 setup. We do still do it in a quiet room, though.
Going from 45mb wav to 3.5mb wav doesn't mean 92+% of the data has been removed, it simply means that by various compression methods (including, but not limited to removal of what the compressor perceives as non-audible signals and superfluous information) 45mb of data can be represented by 3.5mb of data.
You're definitely losing 92% of the data; you're definitely not losing 92% of the information, but that's a different thing.
I've read that thread before and it never really seems to get into microkernel vs. monolithic, it's really more about Andy starting a fight by saying "Linux is losing" and then Linus responding, in his fasion, though most of the skirmishing happens outside of the kernel structure argument.
Linus basically says, "Yeah, it's monolithic, but it provides a complete Unix userland and runs on i386 and is libre." AT's response is "What difference does it make if it's libre if you need this weird 'Intel' chip that no one has to run it, and only the 'elite' has FTP access to download your code!" (this was 1992). Tenebaum is also pretty dubious about Linus being able to "herd 1000 prima donnas" and keep Linux kernel development on track. There's a little sniping over how a monolithic kernel has multithreaded filesystems "for free" and Linus makes a revealing comment about how he thinks message queues are "ugly things" (little remarks like this give you and idea about how much Linus hates the very idea of messaging). His point in the end is that though his kernel was (at the time) not portable, it was quite compatible with any Unix software existing at the time, and that hardware agnosticism wasn't as important as providing a stable and ubiquitous platform.
Exactly what restrictions are they putting on your use of it?
The issue is not that it restricts use, but that it's triggered by use. The GPL does not apply to people who USE GPL software, only to people who redistribute it; a major principle of F/OSS is that no legal encumberance should be placed on users at any time, to use a piece of software in any manner for which it may be suitable.
SVN keeps a.svn metadata folder in each normal directory; hence if you have 1000 normal directories you get 2000 directories.
Many people have noticed this is a nasty problem when you're on OS X and are working with documents which are NeXT Bundles, a class that includes all applications and most productivity formats (excluding MSs). If I checkout a Numbers or Pages or RTF document with images from a repository, SVN will put it on my system with a.svn dir inside the document's bundle. If you open the document and then save it, the app will overwrite the whole of the previous document, which was in fact a directory, deleting the.svn directory inside, and having the effect of removing the document from revision control. Xcode uses bundles too, but Apple appears to have coded Xcode's saving behavior to allow the.svn directory to persist inside its project document bundle (though this is a one-off behavior; this doesn't happen if you use the standard file wrapper APIs to save a bundle.)
Many OS Xdevelopers are looking seriously at git, since it's doesn't do this (we just need some better integration with XCode's UI).
It isn't really a database thing, it's the web frameworks (of all stripes) and CMSs that don't provide a good caching mechanism for static content. And even on platforms that do provide it, like Ruby on Rails, the devs rarely take advantage of it, since you usually have to be explicit about using it.
That said, a slashdotting will not stop at the DB layer, and will probably eventually jam the web server on most people's setups.
Actually, even with an expensive audio kit, most people can not tell the difference between 160kb and CD quality
Stop listening to Enya and put on something with cymbals, it'll pop right out. MP3 works on the theory theory that people can only perceive a spectra of sound over a space of time, on the order of many milliseconds long (far longer than most audio frequencies). You do a fourier transform of the audio over several milliseconds, picking your bands carefully for what people can hear, and you save that to the file instead of the stream of samples (there's a lot of other stuff with data compression and noise shaping, but this is basically the idea). You then untransform back to time-domain on the receiving end and voila.
It doesn't work however, when you have sounds with a complex spectral character with a strong attack transient that last less than the length of the MP3 frame, things like cymbals and drums. The encoder just takes the cymbal's spectrum and smears it into the entire length of the frame, mushing it up. AAC and AC3 do similar things, though they do more work keeping the high-frequency transients sounding right, by varying the frame length based on the content, and using more complicated models of high-frequency perception and envelopes, etc.
256bit MP3s from CD media is a waste as theres no additional data to encode
Are you quite certain of that? 44.1/16bit PCM is a little south of 700 kbps; you're definitely losing something if you're gutting more than half the data, the data is certainly THERE for the converting.
In a lossless format, it would be impossible to tell from the original.
Lossless formats can be watermarked too, they just do the steganographic process on the raw PCM. Lossless just means "You get what you put in," not "You get what sounds perfect"
My limited understanding of relativity is that something can't accelerate to or beyond the speed of light, but technically nothing prohibits something that is already moving faster than the speed of light.
Tachyons, particles which must move faster than light, because they have imaginary rest mass.
They probably don't actually exist, since nobody really has come up with a relation between complex numbers and mass, but then again when Dirac wrote his equation, he noticed that taking the root of a polynomial gave him a plus-or-minus, and made a prediction simply on the basis of algebra that their should be a particle with opposite charge and spin to electron, and he was right.
I wonder if they'd consider open sourcing it. It's very Mac-centric, and probably a mess, but it'll at least be carbonized, and there's probably a lot to learn by looking at it.
Psych care is OUTSIDE the responsibility of the schools. Their job is to EDUCATE.
If kids are acting out, or their emotional issues are affecting their education, than it might fall under the responsibility of the school; kids are human after all, they aren't instruments of education.
A teacher's alternatives to calling in a counselor:
Show attention to the student yourself, to the detriment of the classes time.
Send the kid home with a note saying "We can't properly educate your child until they receive counseling, they are disrupting class and are tentatively suspended." (It would be more polite than that but that's the gist of it.) This has a sort of logical appeal to it, but it's extremely harsh, and there's a good chance the family might just elect to keep the kid home, which might hurt their grade promotion. In order to provide a chance for kids to stay in school, you have to provide a care system for kids who's parents can't afford counseling, and you end up where you started.
Don't acknowledge there's a problem. This might be efficient, though the child learns the lesson that their pain is meaningless to others in authority. They might have to face this in adulthood, but getting subjected to that as a child can cause serious damage. Kids look to their teachers as models for all human behaviors, not just for fact-dispensing; they're the first non-parent adults they have big interaction with, and if teachers show indifference to the suffering of others, you'll have a class full of little Boys from Brazil. (Is that a Godwin? I think I just dodged it.)
They didn't cut and paste from Linux, they took it from BSD, and in the open. The BSD license "Regents of the University of California" attribution was in their copyright for a long time, though they did rewrite it (I think) for Vista.
"The purpose of the suit is to harass and discourage rather than win. The law can be used very easily to harass, and enough harassment on somebody who is simply on the thin edge anyway, well knowing that he is not authorized, will generally be sufficient to cause professional decease. If possible, of course, ruin him utterly." --L. Ron Hubbard
Different end in LRH's case, but the same means. The tort system, without careful rules, is just a big harassment system that rich people can use on poor people.
Refer to TFA:
[...]For purists, it's the Dark Ages of recorded sound.
"You can get used to awful," says record producer Phil Ramone. "You can appreciate nothing. We've done it with fast food." [...]
These studio professionals bring their experience and expensive, modern technology to bear on their work; they're scrupulous and fastidious. Then they hear their work played back on an iPod through a pair of plastic ear buds. Ask Ramone how it feels to hear his work on MP3s, and he doesn't mince words.
"It's painful," he says.
The article is about music people who are complaining about the poor quality of MP3s; why would they complain loudly about MP3s but not about compact cassettes or 8-tracks? It's just a strawman to attack MP3s qua MP3s.
You make a good point. Musicians weren't complaining much when the labels were selling their music on 3.375 ips quarter-track Compact Cassette with Dolby A, I don't see why they should make such a stink over MP3s "ruining music" -- of course, they have other questionable reasons for thinking this. The loss from the 15 ips 2 track masters to cassette is really devastating, when compared to your average 128k MP3 or AAC.
I think they really shouldn't complain too loud. After all, a song in MP3 is at a dead end in terms of generations; any conversions from an MP3 to any new lossy format going forward is going to be unbearable. The last thing greedy musicians would want is to bring attention to the low quality of MP3s, and implore everyone to switch to a lossless format. If someone is "stealing" your music, you should console yourself with the fact that they're only stealing 10% of it, in a format that will one day become obscure, as all formats do, and will be unconvertable into new formats.
It's market cap is still a little bigger than the cost of the tables and chairs, just a little, but if it realizes the liabilities that the court will eventually put on it, it's in the tubes. The most valuable thing for sale might just be the letters "SCO"... maybe Linus should by them (like how the Scientologists bought the Cult Awareness Network trademarks in the 90s.)

It's been such a long time since I thought about negative zero... See Count, Compare, and Skip.

If the copy deprives the copyright holder of a sale by replacing the original, then it's an infringing copy.
If you don't think distribution of MP3s deprives artists of sales, then no, but I don't think this is universally true.
As well, just because it's 10% of the DATA in a PCM stream doesn't mean it's automatically 10% of the INFORMATION.
