Towards the end of the video, the officer in fact alleged she had kicked him. It's not clear to me when that happened. Possibly her foot scraped his leg in the initial scuffle to pull her out of the car. Alternatively, it may have happ

Just to clarify, I meant efficient from the perspective of business, not efficient from the perspective of mathematics. In industry, often a solution which "works", but is neither mathematically "efficient" or "eleg

A good proportion of maths olympians go into mathematics in academia rather than into industry. Industry does need problem solvers, but maths olympians develop creativity and a sense of elegance and beauty as well. Industry requires efficie

You just have to click numbers, each next to the previous one. The total modulo 10 is shown. Once it reaches zero, your score is updated. You want that to happen before your time runs out, but you get a higher score if it doesn't happe

After reading the article I was left with the distinct impression that "constructor" is a name for something they suppose must exist to solve their problems and that the mere act of giving it a technical sounding name allows them

It didn't fly back. It bounced, as in what goes up must (unless it achieves escape velocity), come back down. The comet has gravity, just like earth. Just not much, because it is much smaller than earth

If they could use southern Rhinos as surrogates, doesn't that imply the southern and northern white rhinos are the same species? So we are not talking about the extinction of a species here, only one less habitat for a species? (Not th

It's an important question because the article claims "The applications for a device that functions as these appear to would basically replace every form of transportation and thrust invented by humans to date. Such a device would

Comparing the Chinese results with the American results, it seems that raising the wattage by a factor of 50 raises the thrust by a factor of 15000. That's somewhat hard to believe. On the other hand, the linked pdf from the Chinese te

Fly hearts are unrelated to mammal hearts. Flies belong to a completely different phylum. Pretty much everything about the organs of flies is different to humans. They don't have lungs, they don't have a brain, but a cerebral gang

I would only use this if the first time I appeared on a website it asked me whether I wanted to add it to the list of sites I wanted to explicitly support. That may seem intrusive, but otherwise this is going to (further) encourage content

The GMP (GNU Multi Precision library) guys found that the hand written assembly sequences (which were already 2-6x faster than that produced by a decent C compiler) could be sped up another factor of 2x by superoptimisation, at least of out

No, I don't believe it was a cause of anxiety. The bloating, excess (trapped) wind and associated discomfort caused very unpleasant sensations which triggered dizziness, panic, etc. If you've every been really constipated, you&#x2

You mean O(sqrt(n)), not quadratic. And given that the most obvious algorithm there is (check every possible divisor up to sqrt(n)) is O(sqrt(n)) arithmetic operations, I think it is fair to say this is not an important result. I suppose it

Summary of paper: All n = 0, 2, 4 mod 6 are divisible by 2. All n = 0, 3 mod 6 are divisible by 3. Thus all primes are either 1 or 5 mod 6. If n is composite and 1 mod 6, n = pq with p, q > 1 such that both p and q are both 1 or both 5 m

I'm very surprised by those figures. Is that saying of 58 people studied, if 2 more people had stronger negative effects to placebo than Gluten then there'd be no discernible difference between placebo and Gluten? How does that sh

In my case, I can't have had any severe gluten issues (at least not intestinal ones) until age 37. Another really strange effect is that since stopping with gluten I have had very vivid childhood memories. I don't believe I had &q

I too thought gluten intolerance was all in people's minds, except for Celiac (which is a very serious affair indeed). I had pretty bad intestinal problems for a couple of years. I had effectively ruled out gluten as a possible cause b

He's 2.5 years out of his undergraduate degree. This is incredibly sophisticated code and documentation for such a person. Quite aside from the language, the person himself is worthy of note!

I was somehow under the impression that getting things into orbit was not about getting them high, per se, but getting their velocity high enough to keep them in orbit. Is there really an advantage to flying the rocket up in a plane?

This is the first post mortem I found online relating to Google Foobar. I just ran out of problems today, in the middle of level 8. The questions were certainly interesting, and I agree with the summary of the person who wrote the blog post

I just discovered that blogs and other self published resources may not be used to establish notability for Wikipedia. Basically Nim cannot ever become notable unless there are press releases about it or peer reviewed papers written on it.

I'm not really implying that. Somewhere or other it says Andreas is working for a top secret startup and is always trying to start his own. What I'm saying is that it can be misleading how much academic institutions are "behi

I doubt academic institutions "sponsor" programming languages, other than paying the salary of some of the people who happen to be writing them. Where is Rumpf? MIT? http://web.mit.edu/nimrod-lang/arch/i3

I really dislike this policy when applied to programming languages. Things from pop culture are going to be referred to pervasively in the media and blogosphere, but programming languages don't get there without massive marketing pushe

I was vaguely aware of this. But where are the major design decisions publicly discussed? If you look at the Julia issue tracker, you'll see an enormous amount of discussion between and with core devs about language design decisions. I
