They found a vulnerability *in a piece of hardware they developed* --- there are other valid receivers beyond the one they developed. This means quantum crypto is still possible, just not with the kind of receiver they broke.
"If factoring becomes easy" --- factoring is just one problem whose difficulty can be used to create a difficult-to-break encryption system. The discrete log problem is essentially different from factoring, and would still be secure if factoring were easy; there are other such problems that can also be used.
That's a pretty good analogy. And, taking it further, IQ measures the kinetic energy of electrons ejected from a metal with red light shining directly on it. If you use red light, your IQ measurement is accurate. If you use green, your IQ number is irrelevant. If you don't shine the light directly on the metal, but instead approach from a different angle, your IQ number becomes much less relevant.
It's hard to dig deep into rocks without some variety of explosive. It's pretty hard to plant explosives well. The Mars rovers have a rock-digging tool, the RAT: it regularly measures its dig depths in millimeters. This project wants to dig in and learn about well below the surface: we don't really have a good way of doing this right now without smashing stuff.
We can always recycle this variety of space junk once we get there: this is patently untrue of genuine junk in space. The usefulness of a ridiculously high-tech junkyard cannot be underestimated.
But 'organic' as used here is referring to certified organic food, which means it follows a set of regulations. Sure, technically some of the worst killers are 'organic' -- but they are quite not permitted under the set of regulations governing the word 'organic'.
To sell food as organic (USDA standards), it must be grown inside 'buffer zones' that are to protect against pesticide drift. Sure, it still exists; but 300' is a major buffer to drift over.
Recently I was forced to live without a refrigerator. I bought a few heads of lettuce from the local supermarket; and I bought a few from the local organic farmers' market. Stored under my bed, 80 degree temperatures. Supermarket lasted one day before it was mush; local+organic, nearly a full week.
But, the bigger problem is the claim that they're just as dangerous as non-organic pesticides. Note that by the USDA organic regulations, there is an upper limit to the concentration and frequency that pyrethrins can be used. And pyrethrins really are the strongest pesticides organic farmers can use.
Oooh, this is an awesome idea, let's spin a rocket end-over-end near the capsule! That way it can fly apart from centripetal force *and* shoot rocket debris in a giant cloud!
Last time I experienced this sort of stupidity, the program was a proxy/filter, and the solution to Linux was 'Windows/Macs only on campus.' Best of luck.
So, slightly offtopic: I've recently been accepted to both Stanford and MIT. I intend to go into computer science, not computer programming, with a focus on biology*. They both cost the same $200k, have approximately equal appeal to me, &c. Do ya'll have any anecdotes on which is better? (Alternatively, I could go to Rice for a total of $24k - they're offering me a rather indecent scholarship. Is the quality of Rice education plus 180k saved better than MIT or Stanford?)
*I'm ranked something like 14th on the USA Computing Olympiad, the algorithms competition for high schoolers, but I'm more like 400th on USA Math olympiad. I could major in math; I just happen not to enjoy the math major unwashed stereotype.
Many thanks for your replies and non-offtopic-moderations.

No.

UML is possibly the worst-maintained part of the Linux kernel. Don't try building it in any recent kernel. It won't compile.

Wolfram, obviously. It's why he came up with A New Kind of Science, and not anyone else 20 years earlier.
