Rather than resort to more sophistication in terms of voting and/or flagging systems, I am inclined to think the best hack would be a social one: Make the link to the guidelines more prominent. Why not place it in the bar at the top of ever

by graphene 17y ago
But there wouldn't be a relationship, since the flags would be anonymous, and I presume filling in a comment would not be necessary for flagging. Given those two prerequisites, I think it's a great idea.

The only way you will see FP doing massive parallelism at speeds even close to current best is if they wrap the C MPI interface, and I have yet to see any functional message-passing APIs which aren't tarted-up imperative environments True

It's interesting that in Norvig's talk you linked, while praising python, he also mentions that he is a supporter of the functional programming style for scientific work, both because it more transparently mirrors the mathematical formulati

The link between education of workers and their wages is indeed probably less direct and/or strong than he makes it out to be. However, the increases in productivity you mention have to come from smart people thinking hard about how to do t

You are right about ice, but metals (which are comprised of neutral atoms which lack an intrinsic dipole moment like that of H2O, and nearly always have crystalline structure) are not held together by Van der Waals or similar forces - one n

My apologies if I've annoyed you, that really wasn't my intention. I've enjoyed this exchange, and would be unhappy to have it end on this note. My questions were genuinely meant to structure the conversation and probe your thinking, not to

Something that might have something to do with this is the difference between the DRAM in RAM and the SRAM on the CPU die. On DRAM, the bit is stored as a charge on a capacitor, which is (apparently) susceptible to cosmic ray bit-flipping.

Well, I don't know... If you postulate beforehand that the ground won't deform, that means it will match any force applied to it, including that of a plummeting experimentalist. On jupiter, the force of gravity is greater, so the force appl

You say electromagnetic interactions dissapear at any significant distance, yet they are responsible for holding materials together? Therefore the rigidity of things around us cannot be caused by the Pauli exclusion principle. Not true. T

But if one atom "tries" to pass through another, the electrons from both atoms will be spatially very close to each other, and consequently, they will be occupying very similar states. Coulombic repulsion certainly also plays a role, but it

If that were true, why doesn't all matter stick together in one giant gob? If the structure of an atom is "obviously" affected by the exclusion principle, why would the structure of materials, made up of atoms, make any difference? In fact,

Because that's just the way they are :-) More precisely, no two electrons can ever occupy exactly the same quantum mechanical state. http://en.wikipedia.org/wiki/Pauli_exclusion

this doesn't really comapre the two forces qualitatively I think.. Suppose you did the same experiment on Jupiter; you would fall a lot faster but the speed of decelleration wouldn't be affected. Perhaps on something like a neutron star the

fascinating story.. kind of a blemish that the article contains an error: a virus which can't get into cells is just a scrap of amino acids waiting to be destroyed. To the best of my knowledge, viruses do have DNA, if very little. That is

technically, I don't think that's quite true; a company can book profits even as it's paying off a loan which is bigger than the profits or even than total turnover as long as (operational cash flow) - (interest payments) > 0. I think i

that's not the case, the physics in fact is very different for a single atom than for a lump of metal. A single atom has very specific set of electron energies as a consequence of the electrons being confined to the area around the nucleus.

about the brightness at the ends - I'm pretty sure that is due to the fact that this is a pi-conjugated system; that is, the pi-bonded electrons can jump around the whole molecule. This, together with the fact that the molecule is finite in

An aspect of this I feel hasn't been addressed is that in this case, the product of the commercial activity is information (in the form of a map), which has a reproduction cost tending to zero. This will of course make it difficult to sell

Eurozone != EU When you sum the GDPs of Euro using countries, you get 12.23 trillion dollars, or slightly less than the USA's GDP ( http://www03.wolframalpha.com/input/?i=eurozone+gdp+vs+USA+g... ). How the size of an economy correlates wit

The difference is that the satellites' 230 W/m^2 is in a very narrow frequency band, and can thus be harvested and converted efficiently, where solar radiation is mainly at much higher frequencies, and, more importantly, spread out over a w

To address your second concern, all quantum particles (this includes photons) have wavelike properties (including wavelength), and thus can show wavelike effects, such as interference. For example, a ray of light contains a huge number of p

Even if the loophole for books is smaller, the point is, it only has to be applied once by anyone anywhere, after which it can be shared freely like any other non-DRM'ed file. I'm not convinced that the total amount of internet sharing of a

In Belgium, all engineering students are put together first for three semesters of general introductory courses, after which students choose a major and a minor out of the classical engineering disciplines.

I think it would be better to delete the eintire paragraph above your addition, as the notion that this theorem guarantees at least one cyclone somewhere on earth is ridiculous.

Me personally, no, but I can imagine that this would be attractive to a small business. Anyhow, isn't the effort to port the app from being desktop-based to server-based minimal since all the interfaces are web-based?

another thought: maybe you could sell this as an app you can install on a (commercial) server of your choice, and so not have this drain your local (presumably home) bandwidth, while still being independent of google, flickr, etc. This woul

the philosophy would be the main drawing point for me; it's precisely the reason I still keep all my photos, calndar information, files, etc. on my local machine, even though web-based access would be very nice to have. With you app, I can
