_Real-time_analog_circuitry_ has "NO LATENCY"[1].

[1]The closest thing you have to latency in these circuits is slew-rate, which is measured in volts per _nano_seconds. There are also the phase shift/distortions that the GP mentions, but the truth is these are practically impossible for humans to perceive in any real sense. 'specially for audio frequencies and circuits that aren't garbage.


MS Design Lets You Put Batteries In Any Way You Want 453

jangel writes "While its strategy for mobile devices might be a mess, Microsoft has announced something we'll all benefit from. The company's patented design for battery contacts will allow users of portable devices — digital cameras, flashlights, remote controls, toys, you name it — to insert their batteries in any direction. Compatible with AA and AAA cells, among others, the 'InstaLoad' technology does not require special electronics or circuitry, the company claims."

I can't believe I'm responding to such an obvious childish troll, but the hell with it, I'll bite this time :) With a car analogy no less!

I don't build my own cars. I don't have the tech, time, and general wherewithal to do so, especially to modern North American standards.

What I _DO_ do however, is learn how to use the features of the car and know how to drive it defensively, as opposed to thinking I should be able to snooze at the wheel.

That's the point the GP was making, making the whooshing sound as it passed you by.

No, no, and no.
Unless you _want_ to eventually toast your amp (or in rare cases, your entire house) you do not want to use long lengths of 20/22 ga. unsheilded pairs (that have been daisy-chained God knows how many times) for audio power. Nevermind the likely impedance mis-match. You _also_ do not want unbalanced line level signals going over unsheilded wire, lest you love hearing 60 Hz hum, AM/CB/HAM radio, and AC switching 'pops' over your music. And the pot idea may work well for line level, but definitely not on power signals.

Telephone cables work well for telephones/RS-422/etc... For any other uses they are generally garbage.
Just say no to 'recycled' phone lines.

Comment Re:Deliver the audio via FM-radio (Score 1) 438

I doubt any of these will auto-level like you suggest, but often the computer will do that anyways (see ReplayGain and the like). So set up your audio library to normalize to the same audio level.

As for finding a clear frequency, yeah, I never thought of that one ;P Rural areas should have no problems; high density metro areas might be... and your idea of odd spacing is a good one, but many 'digital' radio these days are designed to frequency step at 200kHz. Remember, YMMV :)

Comment Deliver the audio via FM-radio (Score 5, Interesting) 438

A serious solution that is neither expensive nor foolishly complex? Try connecting an FM-band microtransmitter to your server's audio output and using a remote control system via an HTTP-based system.

Any internet connected machine will control the audio programming, and any old FM-radio will do the trick of receiving the signal. Simple. Effective. _AND_ Wife-Friendly(TM) (at least, according to my wife ;)

Because of FM-modulation, this technique is not hi-fi. But a decent transmitter does an admirable job in retaining audio quality.

Which is _exactly_ the problem in Western business nowadays. That's the point. We're putting all of our eggs in the wrong baskets. We overvalue the wrong skills and traits. Folks who operate on par with whores and mobsters should not be the pillars of an economy.

Really. That's the whole fucking point! We value all the wrong things...

Comment Re:Erm.... Labs? (Score 1) 165

Heh. You see, for those who are forced to take certain subjects in their first year simply because it's a "requirement", the labs in these courses may very well seem trivial.

Sure, gravity works. But that's not the purpose of the lab. Rather, it's the analytical method that is being explored, as well as the strong links between the pure math and the physical world. And sure, those first year labs are rather dull. (My first uni chem lab was making a solution from Kool-aid. No joke.)

But even by 2nd/3rd year chem/physics courses, you were doing some neat stuff. Like using real radioisotopes and Geiger counters to measure the half-life (and hence determine the isotope itself) of an unknown element.

Think Timmy's chem set will include some radioactive Cesium?

But again, this is speaking from a "hard physical sciences" point of view. CS "labs" are really more "assigned time in your schedule to do assignments". Same for Math. Indeed, YMMV :)
