On an abstract level it does seem better to have a large number of young people to care for a small number of retirees, but that would create an unsustainable pyramid scheme in a country like China. Many parts of the world are already overpopulated and low fertility is pretty much the best case scenario.

All of that aside, I also think that there are factors more important than the relative number of old people in a given population. Technological development, public health, etc. are all probably more important, and some of those factors are at odds with high fertility.

Almost always go for the higher offer. As odd as it sounds, company value the higher paid person more, it's almost a rationalization on the part of the company.

One more thing: never accept counter offers from your current employer.

At the beginning of the century (20th, that is), people were already afraid of a world with 2 or 3 billion people. They predicted mass resource shortage, wars and so on. But overall we could cope, and population has been increasing steadily ever since, and we have never had so few cases of starvation as in modern times. Most people on Earth live now better than their ancestors. There is a huge amount of progress in quality of live versus one century ago, even in the developing countries.

10 billions won't be more of an issue that jumping from 1 to 3 was. It's actually a smaller increment vs where we are right now.
> "These are people who are at the very end of their rope who are begging other human beings for money so they can eat"

This is the standard liberal refrain when it comes to homelessness. As compared to "These are people too lazy to work for themselves and sustain themselves on the handouts of others" argument we hear constantly from conservative camps.

Neither argument hold a lot of water, and in the end the homeless are considerably more complicated than either simplistic argument would suggest. Both arguments are deeply unfair to our society and the homeless, as it ignores the primary issues surrounding homelessness in exchange for simplistic feel-good fuzzies.

You've conveniently ignored the big, giant, planet-sized elephant in the room: substance abuse and mental health in regards to homelessness. Without addressing this it is impossible to know what side of the line this homesless-wireless-tower thing finds itself. There is a large (I'd argue vast majority) of the homeless demographic where this would be absolutely exploitative, and there is a much smaller demographic where this may actually be helpful. Without knowing more details about how this was executed, it's impossible to say what's what.

> "where they were yesterday when those homeless people didn't get $20."

Perhaps, giving $20 to an aid organization.

Directly funding the homeless is an issue that we can argue about till the cows come home and never come remotely close to consensus. Suffice it to say, there are many, many, legitimate concerns about its efficacy, and the money can be just as destructive as it can be rehabilitative.

There is also the notion of whether or not rehabilitation should be a goal when it comes to homelessness.

... All in all, incredibly complicated and without easy answers.

Ask HN: How is your tech team organized?
Our tech team is a department of around 30 people within a fast-growing startup. Our product is a web application that has both internal and external users. The tech team is composed of software engineers, operations people, product managers, designers, and QA people. As we grow, we are trying to determine the optimal way to organize ourselves, how much hierarchy to introduce, what roles to assign, and so on.

I am curious how other teams of around the same size have approached this problem. How many managers do you have, and who are they managing? Who reports to whom? What processes do you use? What works well about your org? What mistakes have been made?
Coudlent agree more. Py3 was/is a shocking disaster. All this work and effort for nothing...except crap that most people dont care or know about...like how Unicode strings a dealt with internally and stuff.

Things that would have made Py3 enticing to me:
- JIT
- Real GIL improvements (no changing from op-slicing to time-slicing is not a real improvement)
- Better OO. Roles, traits, enough with the duck-typing.
- Anonymous subroutines/multiline lambdas. Creating closure generators is too much work in Python compared to Perl.
- Tail recursion
- More stuff that will come to me after I click "submit"

Well, it is a different type of consumption. I notice you can buy the right to have an Ant-species named after you, and be acknowledged in a journal. If I had the dosh/partner, I could understand this. Name the ant species "<partner> is really hot".
I'd switch. You're not indispensable. If you were, your current company would match the offer. If you want to be considerate to your current employer then just give him plenty of notice (i.e. don't wait until the last possible moment to hand over your resignation letter but do it as early as possible). That way they have more time to find a replacement and you have more time to transfer your knowledge to the other people.
I think you missed his point with that comment. It's not about minimum wage, rather, he was making an example of literally paying homeless people to act like furniture.
This passphrase-for-a-chain-of-private-keys idea is a nice one, and it lends itself to a bunch of privacy-related plausible deniability scenarios.

In crypto (especially when there's money involved) it's typical to imagine attackers with lead pipes and your knees in the mix; it's nice to imagine you could 'crack' and give up your stash, except it's not really your stash, it's just a little stash.

There are a bunch of other security factors at work here, though. Consider that you need to have a computer you KNOW does not have a keylogger on it, for instance.

The loss vectors for Bitcoin historically have been

a) Client bugs
b) System password attacks
c) 'errors' or theft by plausibly denying operators

These actually can all be mitigated, but not well with current systems. The master generator password is a good addition to the toolkit, but it's not going to be sufficient. So, let's not forget that cool crypto is as strong as its weakest link.

I've been considering how you'd safely allow frequent $1mm+ transactions with Bitcoins recently, and my list involves an unplugged from the net computer, a faraday cage and a professional auditor from one of the big four.
It's quite simple enough for an intruder to install a keylogger to obtain your wallet.dat password. Further, the intruder could easily modify your send-addresses and have you send Bitcoins to him unknowingly. Some sort of secured 2-factor authentication definitely needs to be implemented moving forward.

I'm not sure why you seem surprised; this is a very long standing trend. It's also pretty obvious. You aren't the only one to value quality of life over quantity; in fact everyone else does too. The only problem is that if you're very poor you don't have a choice. Wherever and whenever the human race manages to claw its way out of poverty, we immediately stop having so many kids. It's not magic.

That being said...

1) What upcoming food shortage? Food production is largely a solved problem. We know how to sustainably produce large amounts of food from a given amount of arable land, and we have plenty of arable land to feed not just the current global population, but the projected maximum global population. It's true! We already have the ability to feed the largest population we'll ever have. True, Africa currently has food shortages, but as soon as Africa stops relying on peasant farming, that problem goes away. We can argue about when (or if) Africa is going to finally have their own Green Revolution[0], but...upcoming shortages? Do you know something the rest of us don't? :)

2) I might ask what upcoming resource shortage, but that's a more complicated question, and probably not worth arguing about. Still, you might want to consider the outcome of the Simon-Erlich wager[1], look at commodity price trends over the last couple decade, and then look at futures prices. Would you take Erlich's side in a repeat of the original wager? I wouldn't, and it's worth noting that Erlich and his ideological allies have repeatedly refused to do so. Again, what do you know that they don't?

3) Also, this is wonderful news for "investors" too (why beat around the bush? Call them "capitalists"; you know you want to...). Trust me, the slavering capitalist dogs are VASTLY more interested in having a rich China full of consumers than in having a poor China full of workers. It might be nice to have cheap Chinese labour making iPods to sell to 300m rich Americans, but it will be FANTASTIC to have cheap robot labour making iPods to sell to 1.3b rich Chinese. (And that's precisely the scenario you're envisioning.) Lower costs and higher sales is how capitalists make their money in the real world.

4) Finally, it remains to be seen how good it will be environmentally. In the short run (say, the next 50 years), it probably won't be. Much as with population growth, we see an inverted curve. Very poor countries can't afford to pollute, and very rich ones can afford not to - but right in the middle you end up polluting a bunch. We went through that period in the late 19th and early 20th centuries; now it's China's turn. They're producing less pollution for every dollar of GDP each year, but their GDP is climbing much faster. The environment is likely to get worse before it gets better. (Of course, look on the bright side: We are conquering global inequality, and the environment will recover eventually. Those are both GREAT. But let's not get carried away.)

Well put in the most succinct possible way. Thanks!
The oDesk of Science
Thanks for the technical writeup. Amusingly it really has embedded in it the very basis of the argument people are making when they say copyright isn't stealing. For example, no one would try to start an anti-trespassing campaign on grounds that it is stealing, they would be laughed at mercilessly. No one would try to start an anti-vandalism campaign on grounds of it being stealing. No one would start an anti-noise campaign on it being stealing. Yet all of these take away alienable rights, and are therefore close enough to stealing by your argument to justify it.

No the argument people make when they differentiate between copyright infringement and stealing is that perhaps the copyright bundle of alienable rights doesn't even make sense. They are saying this whole thing is talked about as theft but the fundamental situation is different, lets get the emotional word "steal" out of the picture. Instead lets call it what it is, and make a note of why these are different and why the rights granted and defended are perhaps outmoded and out-dated.
Bruno Latour writes about this sort of thing as a paradox of modernism, in which nature is purified from society (Boyle) and society is purified from nature (Hobbes), the net result being that political philosophies and matters of nature don't fit together very well.

Flattr is great and they actually do have something along the lines of tracking down people who aren't part of the system. You can flattr Twitter accounts and they will create a 'pending click' for that account which will only be processed if the person tries to collect the money.

The main problem I can see with your system is the difficulty in finding the appropriate person or organization to pay for every single file that the union downloads.
It certainly harms people (http://www.ucsusa.org/clean_energy/coalvswind/c02c.html)

But you didn't really answer the question. How would a libertarian society deal with them? Would such a society ban all coal fired plants, and if so how would it be enforced? Would someone weigh the pros and cons, if so who and how? Would such a society every establish a regulatory body to actively monitor plants and limit their pollution?

There is probably a decent way to communicate to users that the corners are hot, probably via some animation.

For example, running apps are available from the left hand side. When an app disappears (eg. hitting the Windows key), just having it slide over (perhaps even popping out the running windows to see it slot in) would communicate where you need to look for things.

The RHS charms are probably harder, but I think there's a way to do this given a little extra polish.
The Accidental Client by Jeremy Epstein
I totally agree - there is a total lack of responsiveness to any communication or contact by all of these internet giants once their "systems" determine that you are guilty. It is a one-way, dead-end street. Surely, all of them must realize that no matter how sophisticated their pattern matching algorithms and fraud detection mechanisms, they can be prone to error. This may be by design though - these companies have no problem with systems with a high false-positive/Type I error rate (convicting innocent people), as long as they can decrease their False-negative/Type II error rates (letting guilty people go free). This is of course the exact opposite of how the rest of our legal and court systems are designed - and therefore the frustration and dissonance.
High-resolution devices (that includes iPhone 4 and iPad 3, but also every single printer anyone's used in the last 5+ years) are exactly why the spec says what it says. The only other option was to not have a "px" unit in the spec at all.

I mean, think about it. Say you have a 600dpi printer. Take a typical web page that sets its body element to be 1000px wide, because the person writing it was using a 96dpi display. If "px" really meant "smallest controllable dot", that web page would print about 1.66 inches wide. Which is obviously undesirable. On the other hand, if "px" means "the length that looks about as long as one pixel on a 96dpi display" then the same web page would print about 8 inches wide, which is probably much closer to what both author and user wanted.

This is also exactly why Apple did the "pixel doubling" thing on iPhone 4 and iPad 3: it was done to prevent existing content that made certain assumptions about the visible size of "px" from breaking.

> Suppose the more frivolous uses of water were somehow restricted.

Then you would no longer have a free market; people would be prohibited from engaging in transactions that they would have chosen to engage in without the prohibition. In that case, yes, price is no longer equal to marginal utility.

> Alternatively, consider that blood plasma and many life-saving medicines that have no other use are still cheaper than diamonds.

A better example, yes. I would tend to say the "market" in these things is not exactly free either. Somebody should ask Friedman about that one. :)

> And, for the sake of argument, let's agree with the marginalists. Aren't all the marginal values and costs for a digital creation, which can be easily replicated millions of times, practically zero?

Yes.
What are the use cases for expressing "device pixels" in a world of widely varying (both across devices and in time) device pixel densities?
Startup Theming
It's not going to be a problem, precisely because a "px" in CSS doesn't mean an actual device pixel.

And that's because we've had "retina" devices for many years now, called "printers" and CSS was designed to deal with that situation from the start.

If Google makes $500,000 per engineer, it's arguably exploitive for them to pay their engineers $50,000. They can pay a lot more, but don't because they are stingy.

On the other hand, if the Wi-fi operator is making $25 per employee, they just can't pay much more.

Even if you think "exploitation" is bad, it's simply not "exploitation" to offer a reasonable cut of your revenue to an employee.

This also applies to low-cost accommodation. A slum lord renting out crappy rooms for $100 a week is being exploitive if it costs them $10 a week. A Tokyo or Hong Kong style "coffin hotel" offering tiny $100 / week rooms which costs $50 a week is not being "exploitive", it's just servicing people who couldn't otherwise afford accommodation.

Absolute measurements (which no longer exist in CSS) are a sane approach to support different resolution displays that are all used at the same viewing distance.

Using absolute measurements to size things on a web page that is then viewed on a TV (viewing distance in the 5-15ft range), a tablet (viewing distance in the 1-2ft range), and an eyeglass HUD (viewing distance in the 1-3in range) would be a disaster.

The fact that people _were_ using inches and millimeters on the web and expecting them to somehow work across all these devices is why they're all now defined in terms of CSS reference pixels...

Potters, goldsmiths, tailors are all creating things, either solely or in addition to designing them. Their primary output is one of creation of a physical product, not of ideas. It's not until the means of production became very cheap that there was sufficient motivation to control the ideas themselves.

And I'm certainly not making any argument that there is anything immoral about "stealing" intellectual "property", I do not believe that is the case.
This is only true in some UAs.

Gecko has supported fractional pixel values for years in general, though for borders in particular the width is clamped to integer _device_ (not CSS) pixels.

WebKit has been rounding them at parse time (even in cases when 1 CSS px is multiple device pixels) for a while, but they're about to fix that.

I believe that IE also supports subpixel layout. Not sure about Opera, offhand.

JIT and GIL are not language features, they're implementation details. Once alternative implementations catch up, many will look at this again.

The other things are considered to be language features by many, have been discussed to death by developers and users alike, and are unlikely to be changed or modified any time soon.
