Pure/. yacking. Barely OT, barely competent, and overrated. Typical again: moderate or reply?
I have 10 years of C++ and less than 2 of some OO-LISP and I can tell you a few things. With proper knowledge of STL you can do just as well as Scheme, same cleanness, same purety of concept. But it takes a hell more than 2 years to master C++ enough to reach this point.
No, the reason Basic/Java is way more popular than LISP/Scheme is a question of philosophy. The same philosophy behind M$ success: quick and dirty, from the mass of barely programmers to the mass of barely consumers.
Any language, be it Basic, Java, C/C++ or LISP is unreadable when not properly pretty-printed.
C++ and STL would be horribly slow without vtable and all the work done behind the scene by the compiler.
Natural languages (i.e. English) are too ambiguous to express algorithms.
Contrary to some belief, C is way closer to the bare bone machine than LISP.
I like both languages and agree that C++ is more engineered and mature than LISP in many ways. But blind cluelessness has its limit, even on/. <G>
A superlative suggestion, sir, with just two minor flaws. One: We don't have any defensive shields, and Two: We don't have any defensive shields. Now, I realise that, technically speaking, that's only one flaw, but I thought that it was such a big one it was worth mentioning twice.
I'm me-tooing on The Fool's Errand. Some of the puzzles were really devilish, even more so for non-anglophones. Maybe I wasn't looking at the right places, but I couldn't find any puzzle games getting close to it. Or some Apple ][ ones.
However, a little common-sense physics is enough to demolish this scam. I'd like to hear their answers to the following questions and objections. But, I bet they won't do it.
It may be because no B. Sc. Physics is more than 10 years away, all this seems very shallow thinking. Lets' go through the "balls".
There is no such thing as a near-perfect (or even really good) temperature insulating solid material - the only pretty good temperature insulation is... a vacuum. Any decent vacuum over a nano-scale gap is going to close the gap, real quick (especially if there is the strong electroforce attraction between negative and positive semiconductors helping); that's Strike One.
"The only pretty good contraception is... abstinence."
There a very high correlation between heat and electrical insulation. If it is good enough for electrical insulation, it is good enough for heat insulation. Ball One.
Such a Peltier-like device has to work by pumping electrons into the cold side and removing them from the hot side. But injecting electrons into the cold side _excites_ the existing n-doped semiconductor's electron-states, and it's only the rapid migration of those excited electrons away from that layer that removes heat (and the device has to pull away unbound electrons marginally faster than they are injected to provide cooling). It's impossible to extract more electrons than are added without entirely stripping the substrate eventually, and long before that happened you'd see _reverse_ tunneling of electrons into the very depleted cold substrate; here's Strike Two.
If you read it correctly, you'll see that you need electricity. If you think a little, you'll realize it is to pump away those free electrons. No free electrons, no reverse tunneling. Ball Two.
Then there's the claimed energy transfer. At the rate of 500w/cm**2, the hot substrate is going to start generating _photons_ (which have no charge, so they're not going to be bashful about moving _back_ across the "insulating" gap) and they will carry... heat; ergo, Strike Three.
Well, if you are not using vacuum those photons won't go far. But most important, half of the photons will go away from the substrate. This would give a resulting 250W/cm^2 dissipation. Ball Three.
Still, a single layer is not all that useful but think of a thick waffle of these. Then you could transfer heat far enough and fast enough that you wouldn't have a heat differential problem.
For those aren't up to speed, here's a quick description on how the cooling works:
Let's say the substrate has a 3 volts gap and you are using a 2 volts battery to push against the gap. Obviously, this is not enough to allow the electron to cross the gap. Now heat is energy also and there's a statistical distribution of this energy between the electrons. All the electrons with 1 eV of heat energy have (1 eV + 2 eV = 3 eV) enough energy to cross the gap, resulting in a 1 eV energy transfer from the cooling side to the heating one.
If the cooling substrate becomes hotter, you can use a lower voltage on the battery since there are enough electrons in the 1.5-2 eV range. If it becomes too hot, this happens with a zero-volt battery meaning the subtrate probably doesn't work anymore.

I agree that it is good, although on the verge of being bad. But I think you're waxing it a little too hard.
If something is scientifically possible, then it should automatically be moral and good.
It is scientifically possible to cause a thermonuclear explosion in the middle of any city. Some delude themselves that science is always evil, others that it is always good. The concept of good or evil cannot be applied to science. On this point, science is like computer: they both don't like to be anthropomorphized.;o)
I find it disappointing that our moral guardians are deciding that human cloning is wrong and immoral, and I'll never get the chance to clone myself and live beyond my normal lifespan.
This is so evil it must be trolling.
Is it morally right to brainwash your own kid, forcing him to think exaclty like you, replacing his memories by your own? Can it be morally right to discriminate against a child because his genes matches yours? If this clone is legally you, should you be forbidden to maim yourself? Such a moral is dangerous because it belittles the value of human life.
Recentering on topic, some culture having different ethics might decide that some non-life-threatening selection (like sex) are morally right. This is where the application of science gets scary.
