...from my purchase of *exactly* one gallon of gas.

Skin effect is measurable at audio frequencies above 10-15KHz, which is to say, in the top octave of normal human hearing. It's measurable, but not necessarily audible, even for the golden-ears types like I was back in my 20's. Back then, I won bets by telling speaker cables apart, The best one was when someone bet me that I couldn't tell the difference between the speaker cable of my choice and 28 gauge single-strand telephone wire--I picked the thickest stuff I could find, and told him which one was louder. Despite all the pseudoscientific crap when vendors spouted (obTopic: "Dielectric bias system"???), I could tell when a particular cable was a better match for a particular amp/speaker combination--using those same cables with a different amp-speaker combination might sound like you threw blankets over the speaker cabinets, or assigned certain frequencies to random points in the soundstage.

That said, I could never tell any difference that I could conclusively attribute to skin effect.

My ears are shot now, decades later, so it's all moot. Lamp cord can't screw up the soundstage any more than the random frequency dropouts in my ears do. On the one hand, I hate not being able to hear the music as well. On the other, I can get by with merely decent gear instead of the expensive stuff, and use the savings on extra symphony tickets.

The difference is that the plumber can tell you not to flush copy paper, and if you do and the toilet overflows, you get slapped HARD, and the plumber isn't the one expected to clean the shit off the floor. (In an ideal world, the janitor wouldn't have to either. It'd be you, and the plumber and janitor could decide whether you get a mop.)

Imagine a Beowulf cluster of these!

Your IT department isn't nearly fascist enough. Many places won't let any non-IT-supported machine on the network at all (i.e. their hardware, Windows, imaged by them, with special tools to elevate privilege for specific tasks like adding printers).

I can go one better: Try supporting the staff of a church. Computer illiterate *and* technophobic.

s/2^n/n^2/

Right. 2n flips, 2^n compares. Unless we keep using the word "touch", but they do not think it means what we think it means.

I'm presuming that whatever process we use to determine the next pancake to flip to the top doesn't count as "touching" it, only the flip does. Is that wrong?

The Tacoma Narrows Bridge? Several of its segs faulted and its core dumped most egregiously.
