Instance profiles (credentials) are accessible to all users for the life of the instance. Until AWS provides an ability to lock down portions of instance metadata and/or a way to delete early in the boot process, it's much safer to bake your bootstrap key directly into the AMI as root (or specific user) visible only.
2H₂ + O₂ --> 2H₂O + Q

Q is the released energy. If you weigh the molecules before and after very carefully, you will notice that they lose weight (or mass if you are being pedantic about it). That mass loss corresponds exactly to the Q-value (through E=mc²).
Aging is a disease, not a wear-out problem. Now that most of the early-killer problems have been solved, the remaining lifespan curve makes that clear. There are specific evolved mechanisms built in to get the old people out of the way so the species can progress.
I remember reading an IEEE Spectrum article about death rates over 100, and while obviously very high, apparently they didn't increase much. I can't seem to find it unfortunately as it was a good article.
This stat is skewed by the default instance on things like EC2 being Ubuntu or Debian (should note that EC2 is built on RHEL/CentOS). There's an awful lot of people's blogs and one-off websites running on Ubuntu or Debian, sure. Those aren't really "business" use cases.
Exercise for overweight people is important for the health benefits which exist even if no weight is lost. Exercise does help people lose weight. It's probably important to manage expectations - exercise alone is not as good as diet change and exercise combined.

> The results of this review support the use of exercise as a weight loss intervention, particularly when combined with dietary change. Exercise is associated with improved cardiovascular disease risk factors even if no weight is lost.
It is all self-reporting based on the classifiers given to PyPI (NetworkX lists itself as supporting Python 3, Python3.2–Python3.4). It seems like both it and twisted would benefit from a Python3–partial classifier
PHP frameworks generally rely on heavy amounts of caching at every level (database, bytecode, Varnish, etc) to make up for this.

Why this is the status quo is something I also question.

I think it's a function of the airport itself. I have been to Qatar and the security was as simple as sliding my bag in. I didn't have to remove my belt, watch, or phone.

Total time to pass security: 2 minutes.

Total time to pass immigration: 15 minutes. (depends on traffic).

I remember a friend who caught her flight just 10 minutes before gates closed. She made it.

Edit: HaHa. Forgot my local airport. I can get from the entry door, to the Airplane bus in 2 minutes (security + immigration + walking). It usually only have 1 or 2 flights per day and feels very friendly.

Just like the EFF, ACLU, NRA, NARAL, etc.

The job of the ultimatist is to expand the Overton Window, challenge assumptions, highlight hypocrisy, ask uncomfortable questions.

Agree or disagree, our public discourse would be less healthy without ultimatists like RMS.
> Either nobody cares about making those tests perform better

Very few do. Just look at Symfony's complexity , the devs managed to shove proxies into the IoC container to "lazy load services" so you could inject them into the controller class constructors without actually instantiating them until you call a route handler's controller instance method... Using complex class hierarchies in PHP has a big cost, while "raw PHP" barely executes the underlying C code. To be fair people using heavy frameworks come for the battery included first, not really for the speed of the router. And since devs want more batteries, it's unlikely it will get faster.

The food point is interesting. It turns out that over time, it's much easier to downscale bit processing systems than physical machines.

Given Moore's Law, this possibly shouldn't have been a surprise.

I guess at some point we'll have another revolution when it becomes just as easy to downscale, domesticate, and add intelligence to physical machines too.

IoT is not that revolution. Nano and bio might be, but they're a good 25-50 years away.

The mass of a molecule is the mass of its constituent atoms plus the mass of the bonds between them. When those bonds are broken, the system loses the amount of mass one would expect given e = mc^2.

Note: this amount of mass is very small and so is typically left out of introductory chemistry courses.

I was thinking about this a couple of weeks ago, expiration that is. This question raised itself and I've not focussed on answering it yet - if you breathe more then, like forced breathing, can you accelerate carbon loss [beyond that expected by the increased exercise involved in such breathing]; like fanning flames I guess.

Thinking now I suppose an [close] equivalent is probably can you increase carbon dioxide production by increasing oxygen saturation of the air inspired?

>I didn't draw attention to M.E. specifically, you did.

You’re missing the context of the thread. I was replying to someone who singled out the Middle East. From what you say, it seems that you’re not attempting to defend what the OP said, you’re just pointing out that most Middle Eastern countries are producing some number of Islamic extremists. Well, ok, no disagreement there. However, on the evidence we’ve seen so far, it seems that Middle Eastern countries don’t produce an unusually high number compared to many other regions of the world. For that reason, I object to the OP’s singling out of the Middle East as a source of Islamic extremists. It would be better to single out the countries responsible.

I’m still a little skeptical of your claim that most homegrown terrorists in Western countries have Middle Eastern backgrounds. This certainly isn’t true in many cases. For example, the 7 July bombers had Pakistani backgrounds. Do you have a source on this or is it just a hunch?

Well it has less mass-energy total, but the energy is in chemical bonds that are made or broken. You have the same amount of mass in there though.
It's a product of how people look for solutions to problems. When people look at obstacles and constantly say to themselves "I can't do X because Y" they will never be billionaires. If you look at something and say "If I can find a way to circumvent or overcome Y, X will make me a million dollars, let's find a way to solve Y and provide X." That's the reason most people are not millionaires. So many look at all the hindrances preventing them from getting to the finish line that the solution never gets realized and they never make their millions.
"Asian Americans of both genders who are U.S.-raised are much more likely to be married to Whites than their non-U.S.-raised counterparts."
This statement is not actually related to the point I'm making. Of course it will be true (for so many reasons) since people raised in the US are exposed to, and interact with, non-Asians.

There's no general white male preference. I didn't say that. I'm saying there's a small niche of white males who have fetishes, and it exists where there is no nice of Asian men who prefer white girls, or Asian women who prefer white men. I've seen white males go only for Asian women because of this. And because societal norms across cultures is for the men to chase woman, you'll get some small group of white men who will heavily pursue Asian woman.

Also, from the same article:
"Social enterprise research by the Columbia Business School (2005–2007) concluded that while East Asian women statistically prefer East Asian men for marriage, they show no discrimination against White men, causing Asian women/White men pairings to consistently become the prevalent form of interracial dating & marriage in the United States.[6]"

Summary: Asian women prefer Asian men, but do not discriminate White men, so statistically (especially if there is a subset of Asian-fetishizing white men) you'll see more interracial pairings. If one is a latent racist, one might attribute such pairings to an intrinsic desirability for one's race.. OR, one would realize that all things have an objective cause besides the fact that one's own race is always better.
My experience has been that JRuby 9k is slightly slower than MRI in a number of cases right now, mostly because its IR has been completely rewritten, and is still pending a performance pass.

>No, there isn't. Only Fox News believes that.

Here [1] is the first page google returned when I asked for a summary of criticism. Although many would dislike heritage, the critique contains ample references to well respected academics (including some from MIT, Yale, etc.)

Here's [2] a widely circulated report on a paper by a MIT grad student showing a significant alternative explanation to Piketty. Here's the actual paper [3].

Here's Krugman [4], pretty much of the same political persuasion as Piketty, summarizing some serious critique and errors in Piketty.

Here's [5] other economists claiming Piketty had conclusion altering errors in his data (but if I recall, Piketty later fixed some, but not all, of these errors. The corrections are not in the book as far as I know)

Here [6] famous author, economist, and statistician Nassim Taleb proves that Piketty's math is flawed. Here is an easier intro (andother critiques, repeated in the literature) from his notebooks [7, #156 and #158].

I could go on and on, there is ample research going on, but I've amply demonstrated that your claim that it's only Fox News is completely wrong.

>The U.S. has lower income mobility than most nations.

Only when measured as quintiles, and a lot of that effect is the US has larger dollar value quintiles than most. If a quintile here takes $40K to move across and only $30K in another country, you can have people here with more dollar mobility and less quintile mobility. Please check your source for your claim and see if they measure by quintile or by PPP adjusted dollars. There is a difference.

Here [8] is an overview of some issues and references to papers showing how the results change if talking about quintile mobility or dollar mobility.

Related, probably the largest study to day on US mobility [9] based on tracking IRS data found that mobility in the US is relatively unchanged for many decades.

>In general, if you are born poor, you're quite unlikely to ever reach the top quintile of income.

In terms of absolute mobility, 90% of those born into the bottom end up better off than their parents [10, Fig 1]. From the same dataset, the majority born into the bottom quintile do not stay there [Fig 2, 55% leave], and similarly the majority of those born into the top quintile do not stay there [about 55% leave].

So one way to write this would be: if you are born poor or rich, you are most likely to move towards the median.

Your are right.

A little nick pick about TypeScript and I hope that other dislike its influence to ES6/7 too: Microsoft's mastermind behind C# and TypeScript: Anders Hejlsberg was the original author of Turbo Pascal and the chief architect of Delphi. In 1996, Hejlsberg left Borland and joined Microsoft. One of his first achievements was the J++ programming language. Since 2000, he has been the lead architect of the team developing the language C#. In 2012 Hejlsberg announced his new project TypeScript—a superset of JavaScript. I sincerely hope he stays away from ES7 - I don't like his syntax preferences. (ES4/AS3 syntax was already weird as hell, and good that it failed.) ES5/JavaScript 5 was so great and lean - so refreshing coming from C++/Java/C#. TypeScript feels a bit like a Trojan horse that emerges as ES7. As the linked article says "TypeScript: Is basically ECMAScript 6 plus optional type annotations." Or the other way around, they turned the beloved ES5 to Hejlsberg's TypeScript. So don't destroy ES7.
> It's already been tried several times... and unless the big 3 browser makers (google, mozilla and ms) all support a given approach it just won't happen.

Has it really been tried though? I've never seen more than a few half assed attempts without all parties involved. I've love to see them come together to work something like this out; the web as it exists today isn't nearly as snappy or nice as native apps so I feel like something will eventually change here. Whether that's the help of a bytecode implementation or something else I'm not sure.

> And even using a common bytecode, there will still be a compile step which is separate from the source, and requires mapping to be able to associate the bytecode to the source with the same potential for bugs you are complaining about.

Yes there is always potential for compilation to introduce bugs but compiling into a bytecode is vasty different from compiling into JavaScript. JavaScript is a functional language with a lot of quirks; Java bytecode and .Net's MSIL, for comparison, are very raw and fast with as few features as possible. It's significantly better to compile into some form of bytecode for later execution than compiling into another human-readable language.
Yeah (though I don't agree with the Torvalds comment), I basically agree. “Write-only” means “I am the center of the universe, and the plebs should listen to what I have to say and write, but I will listen to nobody: and if you were smart, you would stop listening to me and only broadcast, but if you are not, then you should keep reading my blog.”

It really strikes me as another variation on the Carefully Curated Instagram Feed that contains a million pictures of some hustler douche skydiving or touring Africa, or something. Building engagement with the Personal Brand, etc. I mean, everybody kind of does it, but it's a new level of narcissism to write a blog post about how “I’m going to focus on #1 right now, which is me, and the fact that I am the only one who has anything worthwhile to say.”

If you really want to focus on knowing yourself and being reflective, that's great! But don't “broadcast”. Just be silent for God's sake.
That's The Right Way™ of doing it.
> You do correctly identify that the current state of markets have locked most agents whose only goal os to make money into Nash equilibrium, where "everyone has to optimize for profits"

I have to address this one separately because it is dead wrong.

Nobody just optimizes for profit. You can't do that. At least not if you want a business that will survive the test of time and shifting consumer needs and markets.

You optimize for exactly what I said: profits and the right value/quality ratio for your customer base.

Example:

Harbor Freight sells cheap tools. Quite a bit of it is crap. Their audience wants cheap tools. Harbor Freight optimizes for profits within the value/quality ratio their audience demands (or in their case, tolerates).

Home Depot does not focus on cheap tools. I think most tools I've seen there are of good quality. They offer tools covering a range of value/quality ratios. You can buy a less or more expensive power drill. In no case does the quality drop down to what you might buy at Harbor Freight. They optimize for profits in the context of what their audience expects for value/quality.

The reason one can't just optimize for profits is free market competition. Home Depot can't squeeze profits beyond what, for example, Lowe's might allow them to. They are just a few blocks away and offer tools in similar value/quality ranges. Therefore, Home Depot management can't be greedy and push for nothing but profits. They don't exist in a vacuum.

Again, monopolies are a different story. Not part of this discussions except to say that it is highly unlikely that companies with real or virtual monopolies are "greedy", again, in the sense of management rubbing their palms while singing pirate songs about how they are going to screw their customers for all they are worth. That's utter nonsense. Companies that have strong market positions will get as much as they can out of the market as possible.

Apple is an example. Yeah, they compete with other phone makers, but they really don't. And they get four times what anyone else is getting for their phones (or whatever the ratio might be). They go right to the point where they'll generate the most profit per quarter without losing too many buyers to the competitors due to pricing. Not greed at all. That's just good business management.
Not technically correct. A small amount of mass is lost or gained in chemical reactions, just like when gravitational potential energy is gained or lost.

If you walk up a flight of stairs, you will be heavier at the top. If an electron changes orbital, its mass changes as well, making it heavier or lighter.

Let's calculate it. A 90 kilogram man walks up a flight of stairs, one story (3.3 meters). The expression "m * g * h" gives us the gravitational potential energy of mass "m" ascending height "h". Evaluating the formula we get 2910 joules. So how much heavier has the man become? Given E=mc^2, then m = E/c^2. As you can see, we'll be dividing by c^2, which is a very big number. The resulting increase of mass is 3.24 E-14 kg, or too small to be noticeable, but still very real: A 90 kg man ascending a 3.3 meters gains 0.00000000000003 kilograms of mass.

Chemical potential energy changes result in mass changes as well. These changes in mass are insignificant at the scale of chemical reasons, but are indeed taking place. So while it may be reasonable to simplify a discussion of chemistry by saying that chemical reactions don't change mass, in reality the changes do take place, just at a very small scale. A starting point for further research:

"Whenever any type of energy is removed from a system, the mass associated with the energy is also removed, and the system therefore loses mass. This mass defect in the system may be simply calculated as Δm = ΔE/c^2"

https://en.wikipedia.org/wiki/Mass%E2%80%93energy_equivalenc...
