Without meaning to contest your deploration of current trends, I'd suggest a workaround.
Accumulate a corpus of innocuous data comparable in size to your chunk-o-random. (I'd recommend a partial backup of your OS.) XOR them, keep the product, and toss the original. When They Come For You, present the product as the key, and instruct Them to XOR it with the chunk-o-random. Presto, intelligible and hopefully non-incriminating data.
If you're using a conventional camera as a receiver, you can probably send about three bits per flash -- red, green and blue present or absent. Multiply this by framerate, pad generously for synch issues and error correction, pick the right encoding, and maybe you could manage a few bytes per second. Maybe you could encode multiple levels per color, but I doubt it would be very reliable.
sorry the recent credit card law revamp you hear about in the news?? it went through the senate and passed 4 to 2.. yes 6 people out of 100 there to vote on it..
Why do "they" "always" mock conspiracy theorists? Because so many of said theorists spew so much garbage. Post a screed with a few dozen "facts", and most people won't be bothered to check every one of them. Some will discount the whole mass, others will accept the whole mass.
That's probably because if you string together six power strips, you're six times as likely to have one bad power strip in the chain.
I don't know if you can even buy power strips now that don't have built-in circuit breakers. If anything, chaining them together should make you SAFER, because if you should somehow come up with one breaker that fails to work, the others will back it up.
This is not like chaining together lots of thin extension cords with three-way adapters, which remains a bad idea. The thin ones can't handle the standard 8/10/15/20A that would trip a central breaker, so you can start a fire that way.
I can sense shorter wavelengths than that. Only at pretty high intensity, though, and there's a latency period of a few hours before the sensation really picks up, and then it takes several unpleasant days to extinguish. And then there's the peeling.
HST does not operate in the visible light range and images you see are colorized from data gathered from several instruments.
How's that again? I'm seeing that it handles wavelengths from 110nm (hard UV) to 1100nm, or maybe 2300nm, or maybe deeper IR than that. Visible (400-700nm) is smack in the middle of that range, and well-covered by the instrumentation.
...now all we need is a fuel that comes in the form of a long string, and we can finally express fuel efficiency as a dimensionless number.
BTW, 20 miles per gallon works out to 3.4409911e+10 inverse acres. Or, to look at it another way, one gallon per 20 miles is 2.9061395e-11 acres, or about 0.12 square millimeters. That's the diameter of the imaginary thread of gasoline that your vehicle is gobbling, Pac-Man-like, as you drive down the highway.
Turns out thats not enough energy. You need *more* energy that in the entire visible universe. Oh and negative matter (matter that that comes up as a negative for the mass energy tensor in the GR field equations), and thats *not* antimatter.
I've heard this talk about "negative matter" (negative mass) before. Let's see if I get this straight.
If you have two positive masses separated by some distance, they gravitationally attract each other. If they start out at rest relative to each other, they'll accelerate toward each other until they meet.
If you have a positive mass and a negative mass, the gravitational force between them will be repulsive. Instead of pulling each other, they'll push each other.
But when you push on a negative mass, it accelerates in the opposite direction. Remember, acceleration is proportional to force over mass. If mass is negative, acceleration goes in the opposite direction of force.
So, your positive and negative mass repel each other, or try to. The force accelerates the positive mass away from the negative mass -- but it accelerates the negative mass toward the positive mass.
So, slowly at first, but at constant acceleration, the positive mass moves away from the negative mass, and the negative mass follows the positive mass. Eventually, they're chasing each other off to the edge of the universe, within a hair's-breadth of the speed of light. But energy is perfectly conserved; their combined momentum is still zero (positive-something-huge plus negative-something-huge).
...and that's why I don't believe in "negative matter".
In any case, we're going to hit an unclimbable wall soon: just like you can't escape conservation of energy, or mass-energy eqivalence, you can't escape information-energy equivalence. It takes a certain amount of power to flip a bit, and there's simply no way around that.
Build a system on superpositions, and it appears that you can get a lot more done without ever actually (whatever that means) flipping a bit.
Make your computational mechanism reversible, and while you "use" power to flip a bit, you don't dissipate it, which is the critical part.
I'm a big believer in the laws of thermodynamics, and a firm (if reluctant) believer in the lightspeed limit. But "It takes a certain amount of power to flip a bit, and there's simply no way around that" sounds an awful lot like using Shannon's Law to prove that a phone line could never carry more than 1200bps. Er, 2400bps. Okay, 18kbps (those damn Telebit engineers have got to be cheating). Oh, all right, I'll read up on trellis encoding. Okay, 56kbps, but that's my FINAL offer.
And then, of course, DSL and cable made "dialup" and its limitations irrelevant.
AI has been 50 years away for 50 years now. Fusion has been 20 years away for 50 years now.
And speech recognition was 10 years away for about 30 years, but it finally arrived. It was a lot harder than people originally thought, and ended up requiring a lot of processing power -- power that eventually became possible, then practical, then cheap.
I've seen no convincing argument against the notion that the same thing will happen with AI.
I would never get a newspaper. The only things of value to me in a newspaper are the comics, the crossword and sudoku, and possibly the movie listings.
You do realize that all four are available on the Internet for free, in far wider and deeper variety than any one newspaper could possibly carry, right?
I mean, if I can't just pull it out from under the birdcage and roll up the dirt inside it, the way I do with today's print newspapers, it's really not going to work out very well for me.
Oh, fine. Next you'll be telling me that you don't want moving parts in your books. Well, maybe you can explain to my little boy why Mr. Giraffe won't wake up when we open that page in Happy Fun at the Pop-Up Zoo!, or why Baby Roo won't peek out of Mama Roo's pouch any more.
Besides, we've already learned to skip the page with Mr. Angry Monkey.
The representative highlighted my contract that shows I was only entitled to ~512Kbps (if memory serves). I wasn't allowed to complain unless my service went below 512K! On a 30Mbps "connection"!
Poor baby. When I had Verizon DSL here -- 768/128, not bad for the time -- the CIR was 16K bidirectional. That's right, for $50/mo, I was guaranteed that I would get at least half the transfer rate of a 33.6K modem! Both ways!
Thank you for sharing this cautionary tale -- not about the dangers of Adderall, but about the dangers of the War On Some Drugs and its burn-the-village-to-save it tactics.
I believe there was one token European team the year I went (1984), and I think that might have been the first year they billed it as "International". It certainly wasn't drawing from so wide a talent pool then as it does now.
The top two teams were the only ones who solved all six problems. We were separated by a few hours of cumulative time, and I still attribute that difference to the fact that we were stuck with a Hazeltine ultra-stupid terminal instead of the ultra-smart HP terminals that some other teams got. If we'd had Stan on one of the HP's, it would've saved us significant time, test runs, and distraction. (Test runs, and incorrect submissions, both carried time penalties.)
And I don't want to hear whines about vi. We were stuck using a bespoke command-line text editor, in a bespoke limited shell.

Whether there are chemical reactions that produce radio signals, I have no idea.
If you can pump a laser chemically, I'd expect that it would be possible to do the same with a maser.

In the most universal sense.

All things aside, one has to admit that it's impressive that a 1.5 ton vehicle can be motivated to travel 70mph on such a small feed of gasoline.
Or, as I learned to think of it in high-school physics, "it takes a whole lot of motion to equal a little bit of heat".
D'oh! You're right, of course. I meant to say "size". Probably would've been better to go ahead and calculate the actual diameter, though, as you did.
