lot of semi-audio professionals like usb sound cards because there isn't quite the interference with them, that one gets from a sound card sitting inside your case
Then FireWire (a.k.a IEEE 1984) should be even better because you can totally isolate it from the PC via simple transformers for the two data cable-pairs. This will trivially eliminate all ground loops.
I like it. No it's not as configurable as sendmail.
Of course it does not have the rewriting magic that sendmail is so feared for, so it does not support (for example) uucp addressing out of the box, but you can configure exim by it's variable-expansion (and lookups in host/address/domain/...-lists) to do any imaginable mailrouting you would possibly want in that RFC821/822 world of today.
I find the configuration by defining acls, (access control-lists), mailrouters (which convert addresses to methods of delivery) and transports (the different methods of delivery) very logical. And you can add ${lookup_XXX} variables nearly everywhere to have something replaced/rewritten out of LDAP, SQL, text-files, DNS,... So there is really no practical limit for configuring arbitrary comlicated, obscure,... rules for you mail-delivery.
While I'm sure that someone with a clue could manage to run a WinXP computer just as securely and stable as any Linux, OSX,... machine out there......i doubt that someone who insists of having a stupid PC when he could have a Power-MAC instead has any useable brain left...
It's probably your job to keep the network running, stable and secure and therefore I would do nothing... just check for open ports/running services about once a day (that can be automated) and whenever you note something that is against the acceptable use policy of your network disconnect them until it's fixed. That's the way it's done in many places: if you use something that's not approved and managed by IT you will have to care for it yourself.
They want to create work for you (not having a homogeneous{sp?} network increases the workload!)... you will delegate this back to them.
I've had people sign up to get info from a site i run, and upon receiving the first e-mail that they explicitly requested, write back in all caps "HOW DID YOU GET MY ADDRESS??? STOP SENDING ME THIS!!!"
Well obviously you did not manage to make clear to your users that they will receive "Information". I don't think that anyone will list you in a spam-blocking list because you run for example a mailman mailing-list which makes it clear that by entering that password into the form on the webpage (which says that you will join an email-list) you will receive mail from the mailing-list (doh!).

Not only that: I think google's advertisements are much more easy to spot as they have this light green background....
Altavista only has a small bar on the left which is light grey for ads and a little bit darker when the actual results start.
And no wonder the pages loads that slow with all those gifs (which are of course not cached like googles logo on the top left).
I think it's not so easy, at least in the world that we live in.
My naive idea about how chip-features are designed is that the hardware people meet the software people and a discussion goes like this:
We could make a longer pipeline or add more registers or whatnot.... for about the same money/silicon-real-estate/complexity. When would our users and their applications benefit the most.
So the chip is designed with a specific compiler in mind (or at least by people who will have a specific idea of optimizing for a compiler) which in turn is optimized for a specific workload.
And then when you are asked about producing a "real world benchmark" you will most likely create a environment which meets the criteria that went in the design of the compiler which in turn matches your CPU very well..
So I would not rule out that Intel tried to cheat, or at least tried to have a benchmark that matches their CPU best but much of this comes from the way the processors are designed.

If you get a cheap Geiger-Mueller somwhere the natural activity around us should provide you with enough randomness for all your home-computing needs:-). Not necessary go get some additional source for a higher rate!
Get some (up to eight) LM78 chips which you can (usually) connect directly to your parallel port. (use the i2c-pport module from linux-i2c or lm-sensors). Then you can use all usual hardware-monitoring programs that exist for linux.
It's the same like people hacking around SIM-Lock here in Europe to get cheap phones that are no longer bound to a specific service-provider.
I think it's sad, because I would be way more interested in the technical aspects of phones and maybe the X-Box's internals than in the stupid mod-chip itself.
In the X-Box case I would be interested in how they manage to modify the X-Box: Do they alter some bits on the BUS while the X-Box asks for it's identity or is this just a ROM which's contents somehow get executed upon boot? (Or both?)
[The same holds for the phones, I really don't like expensive closed-source software, I want descriptions of serial protocols et al...]
And when you look at those chips: These people know *a* *lot* about the X-Box's internals and it would be absolutely trivial for them to make Linux/NetBSD/WinXP/DOS run on a XBox.

Let me assume that those lectures are not hi-fi recordings and as such you could live with half or a quarter of the audio-bandwidth of your soundcard... Then lets assume that your fast-dubbing-tapedeck runs at four times the normal speed...
Then just grab the signal from the playback-deck and feed it in your soundcard. Record it to a.wav file at 44100 Samples/sec and then encode it with your favourite mp3-encoder telling him that you have a 11025-Samples/sec (=44k1/4)recording.
Now the encoded mp3 should have the correct speed and frequency again.
Of course that would limit your Bandwidth to about 5000 Hz but I'd give that method a try to check the feasibilty of that method.
If it works out halfway useable then you could try and get one of those 96kHz/24Bit-soundcards, that should yield about 12kHz Bandwidth (96kHz recording, 24kHz encoding -> 12kHz BW) which should be more than what you could expect from a normal analog audio-tape.
Of course this totally ignores any frequency dependant effects in the path from the magnetic media to your computer... you may have to compensate these with some filters... maybe there are encoders that have an equalizer simmilar to the mp3-players?

It should work with wrap-around, too...

So the right question would have been to swap two numbers without using a temporary variable and not using...
