I think it's the age thing. I remember 1MHz computers were around for a decade. We just wrote better code to make thing faster. Even the lovely C-64 was actually sub-1MHz (NTSC version, the PAL version was just a hair over 1MHz.)
What's more ironic is that this ex-hippie is doing what little I can to help a retired four-star General stop the US from going to war with Iran, at least until we've tried talking to them.
Audio feedback (also known as the Larsen effect after the Danish scientist, Søren Larsen, who first discovered its principles) is a special kind of feedback which occurs when a sound loop exists between an audio input (for example, a microphone or guitar pickup) and an audio output (for example, a loudspeaker). In this example, a signal received by the microphone is amplified and passed out of the loudspeaker. The sound from the loudspeaker can then be received by the microphone again, amplified further, and then passed out through the loudspeaker again. This is a good example of positive feedback. The frequency of the resulting sound is determined by resonant frequencies in the microphone, amplifier, and loudspeaker, the acoustics of the room, the directional pick-up and emission patterns of the microphone and loudspeaker, and the distance between them.
n telephony, sidetone is the effect of sound that is picked up by the telephone's mouthpiece and reproduced by the earpiece of the same handset, acting as feedback that the phone is really working.
Without sidetone, the user does not hear their own voice in the earpiece and the telephone user may think the phone is not working. Too much sidetone causes the phone user to hear their own voice loudly. They may feel uncomfortable and lower the level of their voice.
Digital telephones lack the mechanical acoustics and circuitry which created sidetone in older phones, so digital phones include electronic circuitry to reproduce the sidetone. Many cell phones do not provide sidetone. Usability experts believe this causes some people to shout, or speak too loudly, when using a cell phone. [1]
Sidetone is useful for people using handsets but can cause acoustic feedback in teleconferencing systems if not treated properly.

Very interesting Bruce! I've not heard of these before but I'll be on the listen from now on. Thanks!

Then don't follow so close. 99.999% of rear ending accidents are caused by following too close. It's also bad for congestion. see: http://amasci.com/amateur/traffic/trafexp.htm
So we'll all breath worse air so you can pimp your car. Go Go Speed Racer!
astounding how many were right.
I sold him my spare. Does anyone want to by an arm and a leg?
Post may contain irony...
Not in this case! Are you sure we haven't bumped elbows in a meet-me room someplace?
Hmm.. bay 6, rack 3 (counting up or down?) position 14... there's a pair already there but the blinky light doesn't work. Oh well, zip zip zip.
ITMFA!

As the saying goes:

Pick two of three.
Those V20s were great. I did rework a VIC-20 to use a 4MHz 65C02P4 once but that really didn't turn out that useful.
Excellent reply ajs! Do you hang out on blogs? If so, email me where, I'd like to read more of your stuff.

I know, I was working in a data center that was surrounded by the Seattle WTO events.
Really officer: I'm not a radical longhair, I'm a UNIX longhair!
Yeah, just think how long Deep Blue would be locked up by the NSA marching against Bush&Co.
I'm willing to bet that 40 million of us got more than a dollar a year worth of postcards. I know I feel I did.
You first name wouldn't happen to be Valentine? Maybe you have a hidden agenda in wanting the MGS to fail. Hitting a little close to home, maybe?
Er, yes.
Does my 4 digit UID give me the right to smack you down for suggesting that the absence of evidence is the same as the evidence of absence?
Good writeup Doug. If I had the mod points today I'd insightful you.

Don't forget about the cop that shot his wife in front of his kids, and then himself. Wasn't he an ex-chief?
I didn't read TFA but was this in the Hilltop neighborhood?
And WTF is Toyota naming a truck after that POS city? (Yes, I lived there, briefly, once.)
I saw your resume. Now go fuck yourself.
I wasn't trying to an asshole. I was just letting you know what the proper term was. You're new here, I was mentoring you.

It's not called feedback. It's called sidetone.
