There's an Abit motherboard or two that have two ATA chips on them, the BX chipset (which has ATA/33) and an HPT chip (ATA/66). The HPT chip allows you to connect another four ATA devices, but it doesn't support booting. This is all from memory, though, so I could have the details wrong. But the point is that you get ATA/66 and 8 ATA ports.
You're right about the four IDE connectors, but the ATA/66 interface is able to be used to boot. However, it did cause a bit of trouble when I had two hard drives on the ATA/66 interfaces, and an ORB drive and DVD-ROM drive on the normal interfaces. The effect was the NT became very confused, and from memory it wouldn't even boot if there was no disk in the ORB drive. But I can assure you that it will boot from the ATA/66 controller. This board is the BP6, which is the infamous dual celeron board. There's also at least one other board, which I think is the BE6, which is the same wrt booting.
Additionally, this means that RPMs don't depend on specific implementations of a generic service. In other words, a properly done RPM will depend not on sendmail, but on smtpdaemon. Can Debian do this?
Yes, for example, sendmail "provides" mail-transport-agent. Other examples include java-virtual-machine, mail-reader, httpd etc. I'm unsure how this works in practice though, eg. if i don't have a mail-transport-agent installed, does it pick one??
The problem with this argument is that Sony is the company behind MiniDiscs. Their advertising has clearly been aimed not at people recording music played by themselves, but people want to copy music from cds. The advertising certainly doesn't make it really obvious to people that it would be illegal to copy cds they don't own. If Sony were so concerned about losing profits from copying of cds, wouldn't they stop selling MiniDiscs?
No, No, No!!! 2N samples will reproduce a frequency N perfectly given decent playback hardware. The DAC simply outputs a level and holds it until the next one comes in. This would produce the sort of output you're talking about. The trick is that a low pass filter is put after the DAC and it will let through all frequencys below and including N and not much else. Any distortion in the original was simply added frequencies. The low pass filter removes these and creates a perfect sine wave!
Think of reproducing a square wave (which both CDSs and LPs are horrible at doing). A square wave contains LOTS of high frequencies. It has to in order to have the sharp rise and falls. THe low pass filter takes out these and creates simply sine waves.
Actually, the red book standard does allow for 4 channels. In fact every track on every cd has a bit in the subcode to say whether or not it has 4 channels. I don't know if there are any commercially available players or even software available.
Anyone with access to a CD Burner can easily check out the quality of mp3s. Just use something like Winamp to decode to.WAV then put this on a CD. Now you can play it in a CD player without the noise from the computer. Try encoding a song at different rates, and put them on randomly. I'd be suprised if you couldn't tell the difference between them.
Re: Battery life While battery life was a problem a few years ago, portable cd players now last much longer. Mine lasts somewhere between 8 and 12 hours, with ESP with just its rechargeable battery. With non-rechargeables it lasts 20 hours. Also, without trying to support the RIAA, the quality of mp3s is far inferior to that of CDs. The compression at anything less than 320kbps introduces obvious artifacts and even 320kbps sounds different from the original. I believe DVD-Audio uses a new lossless compression called MLP which cuts a decent fraction off the filesize while mantaining the original signal. This is the future, not inferior lossy compression. Why sacrifice quality when storage capacity is constantly increasing? However it is important that the cost of entry into the market for bands is as low as possible and mp3 does achieve this goal.
