Interesting study on activity levels and energy expenditure.

http://journals.plos.org/plosone/article?id=10.1371%2Fjourna...

Abstract

Western lifestyles differ markedly from those of our hunter-gatherer ancestors, and these differences in diet and activity level are often implicated in the global obesity pandemic. However, few physiological data for hunter-gatherer populations are available to test these models of obesity. In this study, we used the doubly-labeled water method to measure total daily energy expenditure (kCal/day) in Hadza hunter-gatherers to test whether foragers expend more energy each day than their Western counterparts. As expected, physical activity level, PAL, was greater among Hadza foragers than among Westerners. Nonetheless, average daily energy expenditure of traditional Hadza foragers was no different than that of Westerners after controlling for body size. The metabolic cost of walking (kcal kg−1 m−1) and resting (kcal kg−1 s−1) were also similar among Hadza and Western groups. The similarity in metabolic rates across a broad range of cultures challenges current models of obesity suggesting that Western lifestyles lead to decreased energy expenditure. We hypothesize that human daily energy expenditure may be an evolved physiological trait largely independent of cultural differences.
Your average flight school doesn't buy new 172s. Suckers with a lot of money do. (A new 172 costs over $350k last I checked. One a few years old can go for half.)

What flight schools do buy are the 172P, N and M, in that order. A low time 172P, being the last made before production stopped in the 1980s, commands a premium.
You have it backwards. The term "startup" today commonly refers to what used to be called a "high-growth startup". The fact that new businesses such as SMEs that are not intended as high-growth ventures are using the term is a reversion to the original meaning.

It is no bad thing to have to start using the "high-growth" qualifier again.
This phrasing may sound like entitlement, but try turning it around.

>I have had trouble understanding class numbers. Usually they measure the "failure" of unique factorization. So how does these failures become a special type of number, that multiply to form a group?

That is a very good question. A priori the "ideal class group" is just a set. Why do you get a multiplication rule?

I don't think there is any particularly simple explanation. You might read, say, Cox's Primes of the form x^2 + ny^2 for more, but nothing comes to mind now which I can explain in a short amount of space.

But please know, at least, that you have identified a very important question!

Norway is a different case from most of the rest of the world, we run what's called an IT network earthing system where there is no neutral lead. Everything is connected between two phases getting 240v, and the earth wire is tapped from an actual metal rod dug into the earth.

This setup is pretty much a mess, and can wreak havoc on laboratory setups, so e.g. at universities all the lab rooms are laid out with TN (the standard everyone else uses). This means you can mess stuff up in the lab by running an extension cord from the adjacent non-lab room (e.g. get large ground voltage differences, all sorts of wanky stuff).
The meaning of a statement depends on who the audience is.

In your examples, logically they are both lies. But, the meaning that is being transmitted is something more akin to: there some obvious, if unmentioned, reason why an action would be undesirable. And, this meaning is pretty clear to an average person in both cases.

Obama has logically lied. There is no question about that. But of course, we aren't talking about whether he lied, but whether he implied something untrue.

Given his response, "I can't pardon somebody who hasn't gone before a court and presented themselves", it's pretty obvious that an average modern American would at least assume the implied meaning is that something outside of his control is preventing him.

Therefore, your contention that he could have been implying "I can't because I choose not to", could not be correct, since he knew who his audience was, and having decades of practice as a career politician communicating with that audience, knew very well the meaning they would take from that.

> I was once asked to basically create a clone of Yelp in a week

That's just unfair, inconsiderate and unsustainable, and is also a red flag (ie: I would not go to that company).

Giving up a week of your life for an interview ?

and for free ?

And most importantly -
what if ALL companies did this ? you would have to spend months working from home, for free, just to get to the next level of the hiring process .

I don't know what the solution IS, but I know for sure that it IS NOT a 1-week work-from-home-for-free task .

(edit:formatting and some grammar)

Edit2: people will actually pay good money for a yelp (or craigslist/etc/etc) clone on places like upwork.
And they asked you to do it for free .

Basically both projects achieved their goals, but Midori eventually was killed by management, even though they got an usable GUI desktop running with some core applications.

The Bay Area is very diverse. What residents would object to varies accordingly.

> Smaller apartment blocks (3 stories etc) doesn't have to come at the expense of the lifestyle either - the large European cities I've been to all had thriving neighborhood's , likewise with parts of larger US cities.

Of course you can. That's not the issue. The issue is that in many of these areas the current residents largely do not want this because they don't want the character of the areas to change.

It boils down to how much control you want existing residents to have over planning. This would be equally hard to change in most of Europe in places where you have geographically constrained areas full of wealthy owners that does not want the area to change too much.

While others are recommending platforms to practice, here are my 2 cents. Most important asset for a public speaker is "clarity". Clarity of thoughts is a magnet for audience attention. Once you have an audience "connect", anything you say is gold. Clarity of thought can be improved by these two resource books:

1. Art of Argument - Giles St.Aubyn (ISBN 0800803698)
2. Influence - Robert Cialdini (006124189X)

After that, try reading some Bertrand Russell writings. See how your argument and persuasion quality jumps from above resources.

The difference is that you, as an applicant, want to be part of something someone else created and to use it to feed and clothe yourself.

Nobody is asking for free work. And I definitely would never hire someone that calls a four hour exercise that is part of an application process "an indication you don't value yourself highly." In fact, it would be a huge red flag and I'd throw that applicant'a resume into the trash can.
Good luck with the project, we already have too many kernels written in straight C.

Only thanks to this kind of work one can prove it is possible.
Parser generators really shine when you're experimenting with a new language, whose syntax isn't stabilized.
At this stage, you want to be able to change your grammar nearly for free. You don't want to be trading enhancements of your final grammar for parser developement time ; and you don't care a lot if your parser is slow or your syntax error messages are imprecise.

I agree that the syntax of C++ is still evolving, but nobody would qualify g++ as test bed for experiments on C++ syntax.
The benefits of using a parser generator here are lower - but I certainly agree that having one megabyte of code inside one file is undesirable!

See: http://www.drdobbs.com/architecture-and-design/so-you-want-t...
You can do that with parser generators too. But I agree, in that too many parser generators do things like generate tables instead. In the past I've written generators that generate recursive-descent parsers that mimic how I'd handwrite them, and that is a lot easier to debug than table based generated parsers.

But the reason I've not pursued that more is that once you've added in various exceptions, and tree building, and error checking etc., you're not saving all that much over just hand writing the thing entirely.
At my company they do a technical test for an hour followed by a technical interview. It's like an exam. The test is decisive.

I prefer this kind of tests, as they only require an hour of effort, and they are objective. All the time a technical test was involved I received a quick and good offer. When I had to convince them about my skills just by talking I either got no offer or I got an offer that was way to low for my experience (like half or worse).

As an example, the hardest problem in the test was a C function that receives two parameters, one by value, another by reference, and it did some modifications to those parameters. The problem was further complicated by having two global variables with the exact same names as the parameters that were used to call the function but with the variables switched (global a went to parameter b, global b went in parameter a). At the end they asked what's the value of global a, b?

I've written about this in a recent thread. Google truly needs to face a massive class action lawsuit regarding this.

I hate that sort of thing but they are large enough not to care and the only way they will care (well, at least fake forced care) is if they kicked in the balls very, very hard. The only way for this to happen is a massive class action lawsuit.

It is beyond obvious they have caused untold damage to thousands of businesses who, after deciding to trust their products to create a revenue stream, get cutoff summarily for reasons beyond their control.

> Supposedly Obama knew for Months/Years... that Russia was trying to influence the election. And by his admission BEFORE the election, you could trust the results. Hillary has a well known quote that "If you don't trust the election results, you are a threat to democracy" (Paraphrased).

> If the Obama Administration was worried about Russia influence in the election, why didn't we hear about it BEFORE the results that they didn't like? Why is all the outrage about Russia AFTER the election?

There are two different things going on here, which the right likes to conflate.

Russia influenced the election by manipulating voters' opinions, with means that many consider illegitimate (hacking).

Nobody falsified the election results, by hacking or otherwise. When Clinton said not accepting the results was a threat to democracy, she was referring to that - specifically, Trump's claim that the election was "rigged" through voter fraud. And she did accept the results. Democrats today like to argue that Trump doesn't deserve to be president, but nobody credible is saying that the election was literally invalid and the courts should throw him out of office, or anything like that.

Obama did claim Russia was trying to influence the election before the election occurred - on October 7. [1] It's true that he didn't do more in part because he thought Clinton would win, but he also didn't want to seem to be unfairly influencing the election himself.

There are significant differences between Obama influencing the elections of other democracies and what Russia did: the Russian hacking was (1) covert, not overt, and (2) a violation of US law. Of course, you don't have to agree that those differences matter.

It's a bit frustrating because different people react so strongly in both directions. I don't like live coding, but I'll be ecstatic with a pair programming session -- because I can evaluate them at the same time. Homework, I'm generally OK with, but I honestly hate it when you get a response like "We didn't like your code. Goodbye." On the other hand, I know some people who can't deal with the stress of writing code in an unfamiliar situation.

I wonder if the best thing to do is to simply offer the candidate a choice.
I'd love to see an alternative, but I've seen nothing on the horizon.
