As a grid engineer, I find the Danish case to be somewhat unique because of their strong AC and DC interconnections to Germany and Sweden. Basically, they can free-ride on the large european grid (UCTE), which stretches from Portgual to Russia, to maintain network stability while increasing domestic wind penetrations above 50%.

I think a more interesting case study is Ireland, which has far weaker interconnectors to the UK and operate mainly as an island network. Like Denmark, they are also trying to integrate large amounts of wind (a goal of 40% by 2020, which is equivalent to over 6GW peak), but unlike Denmark, Ireland also have to deal with the resulting stability issues.

An EirGrid engineer I spoke to recently mentioned that frequency stability is already a big issue for them. The main solution proposed in a 2010 study [1] amounted to maintaining a sufficient operating inertial reserve, which would potentially mean curtailing wind generation at times. In the future, I would look to Ireland rather than Denmark for solutions to integrating more wind into the grid, because they are already at the pointy end of it.

He totally skipped over the best argument for Bitcoin, the reliance on middle-men when exchanging money online. You either have Paypal or some other kind of credit card processor that takes %3 or more of every transaction.

If only the value of BTC would settle down a bit, it would make a great way to facilitate micro-transactions.

>Rent seeking can't and won't last [because] too many people have more comfort, want too many things, and are harder to control - and now more than ever.

That's a rather pie-in-the-sky argument. People pursue rent-seeking because it gives them comfort, material goods, and freedom. The businessman who lobbies for monopolistic benefits, the politician who takes his campaign contributions, the copywriter who creates attack ads: they all follow egotistic interests. Wild, unregulated, snake-oil-and-corporate-trusts capitalism is no solution to these problems.
I am a pretty extreme libertarian (kind of a nutter) and keep getting worse at it, but the reason that argument is flawed is that it assumes anyone can own electromagnetic radiation frequency. It is in the same realm as owning wavelengths of visible light. It is a government construct, like patents and copyright, that have no natural scarcity to them, but has scarcity and ownership artificially implied, enforced through violence of law.

The real free market answer is that electromagnetic radiation is information, and you can generate whatever frequency of it you want, and you assume the markets would naturally orient themselves to not interfere devices. I absolutely think that would happen - any competitive entity trying to sell radio devices would have it in their best interest to collaborate across the market to make sure device manufacturers don't interfere, but it isn't at the threat of violence but at the promise of profits people would restrict their band usage. The market would inherently optimize radio usage for the best use case of consumers, to optimize their returns. The inherent competition would create incentives to innovate ways to use less bandwidth, different bands, etc.

That is the free market approach to radio. If you start your argument with "the government starts out owning this unlimited concept of frequency" it immediately is flawed.
Why not a hundred million a year? You could get that many from Africa alone. Because nothing grows the economy faster than a pile of immigrants, except maybe an extinction-level mega-tsunami of immigrants racing toward the coastline at hypersonic speed.

Yep, that would really be great for the economy. Which is of course exactly the same thing as the country.
The notion that inflation is low is a lie. The CPI was substantially altered in the early 1990s to mask the huge increases in prices that have gone on.

Housing is skyrocketing again right now, fueled by a massive inflation binge the likes of which the planet has never seen before. The cheap money is flowing into assets (stocks, real estate), as the Fed said it intentionally wanted to have happen.

Nationally housing values are now climbing at a 10%+ annual clip again (20% in Phoenix, with markets like DC at all time highs), driven by the Fed's inflationary posture of QE + hyper low interest rates. That equates to trillions of dollars worth of asset inflation annually. Housing is one of the most important inflation metrics, and it's going up massively right now.

It's not the economy rebounding causing it. How do I know? Well beyond the obvious QE + low mortgage rates + lack of job creation, we're creating almost zero construction jobs right now (compare that to the last two times housing prices soared).

Stocks have been juiced (inflated) by the easy money policies, leading to an S&P that now has a higher PE ratio than the last bubble. And given that S&P earnings are now eroding backwards, said PE ratio will probably continue to expand beyond that.

College costs? Massive inflation. College costs doubled in ten years against the backdrop of the great recession. Welcome to government inflation.

Healthcare costs? Massive inflation.

Food prices? Near all time highs.

Energy costs? $90 oil, $3.60 gasoline. Both are prices that would have been considered beyond outrageous just 10 or 12 years ago. Now that's the new normal. Meanwhile the US is producing more oil than at any time in the last 30 years, so it's not a supply problem (it's easy to see that by comparing the available supply of oil and gasoline against 2003 numbers). Our gasoline usage is back to 2002x levels, but prices are up 175% or so.

Home prices are up 75% to 150% in most major markets over 15 years. Given incomes aren't soaring, and we have 14.x% real unemployment, that's a dramatic increase.

Even with gold's sizable pullback with the climb of the dollar in the last few months, at $1400+, it's also a price that would have been considered impossible just ten years ago. Ditto silver (up 500% in 10 years) or platinum.

Everything screams: inflation wave.
How do you explain government rent-seeking, where there is no competition? Take government pensions or teacher unions for example.
Would finally get here? What gives you the confidence this will happen in a world of finite resources and where Physics & Chemistry contain rules that don't break (like the challenges of obtaining sufficient energy supplies at an sufficiently high Energy-Return-On-Energy-Invested basis), and where we have a huge population that's still growing, and an environment which appears to be straining under these pressures?

Sure, resources being as abundant as the air we breathe is an idea worth pursuing. Unfortunately it smacks into reality where resources are limited, are being converted into unusable forms at increasing rates and many if not most of the critical ones are peaking or have peaked in terms of production rates.

Still... I long for Iain M. Banks Culture too... sadly I just don't think it's going to happen.
To be fair, only braindead or highly misinformed people thought Stuxnet could have been high school students. No one who looked at it thought that.
Richard Florida's fascinating Rise of the Creative Class purports to explain this. In short, startup culture heavily correlates with acceptance and welcoming of diverse lifestyles, and distaste for conformity and conventions --- things which correlate heavily with social liberalism.
Why do you need an alternate currency to do that? Companies like Dwolla are hard at work trying to make credit card processing payment fees a thing of the past. Last time I checked, it cost only 25c to move money between bank accounts on Dwolla.
Recently a big engineering firm (let's not harm them by revealing their name :) ), called on me. A query on our system takes 7 days they said, when it succeeds... These guys deal with up to 4Tb a day. With proper multi-core map-reduce and open source search, I brought this down to 3 sec on a single 48 core machine.

They used this without revealing it to their (big) customers (who pay a lot for the crappy system). Then they've got a new version of their original system, relying on hadoop. Still, it was slower than the single machine design.

Sometimes the bottleneck isn't in the hardware resources... Distributed computing has many advantages, but I personally use it as a last resort (or I prepare the architecture for scalability, trying to never hit the two machines and beyond case!).
It is a short term problem though. in the long run, free spectrum would mean that in the best interests of all parties involved, they would minimize the interference. It isn't profitable for your stuff to be unusable because everyone else is using the same spectrum.

I believe the free market would naturally orient itself to correct for interference. Overused bands would be fled from, and the balance between saturation and diversity would be manifest by customer satisfaction. There would be frequent, instantaneous (in long run terms) moments of conflict where problems arise, but as a whole it wouldn't be a rigged, exploitable system by the corrupt that govern it.

But we have to argue in ifs, because we have the product of one chain of events. Maybe a system would have arisen with a benevolent market controller who charitably gave their artificially limited spectrum to use. Maybe we would have descended into chaos when our cell phone service got choppy.

We don't know because we never tried the alternative. We assume it is bad because in theory it sucks in the beginning, so we stick with what we know to be inherently flawed because we don't have the incentive to try to fix it.
I missed it... what happened?
Not sure if people notice the last sentence in the article:

"Murphy ran a few other games through it, including Tetris, and found that the program would eventually just pause itself rather than continue playing and lose, a tactic shared by annoying, over-competitive cousins around the world since 1985."
That won't work, the pigeon will stop playing. But a pigeon will recognize paintings by a certain painter, or steer a missile to a target. Relative to the state of the art in machine learning pigeons are fairly sophisticated, so it means little to claim that a pigeon might learn to do something.

I've always heard Krugman referred to in reverential terms, so this really leaves me scratching my head.

Setting aside the near ad-hom based on the fact that people use currency for drugs, he seems to take the idea that bitcoin is anonymous for granted. That means he doesn't understand what he's talking about, and there can't be two ways about it.

Bitcoin can be considered pseudonymous, and in a system where exchanges need to abide by money transmitter laws combined with the fact that every transaction is a matter of public record, the situation is murky at best. And when you actually think about it, if people must identify to exchange bitcoin for other currencies, that might mean a sea change in the transparency of financial transactions.

Krugman, if you read this, think of your goddamn reputation and do some research! There are about a million exciting inferences to be made based on the hard rules of the bitcoin protocol. Start here. http://bitcoin.org/bitcoin.pdf
Surely Bitcoin and its users are social - as can be attested by its viral growth in the last couple of years.
Ask HN: how do I get some marketing/sales experience?
Hi all. Full-stack Developer here with ~6 years of experience (eCommerce, large scale architectures). Recently, I took on marketing/BI side project and fell in love with it. Ever since then I've been trying to gain more exposure to the area, but I am not ready to transition my full time job to a marketing/sales role yet. Anyone else in the boat? Any good tips on where to proceed from here?
That utterly misconceives both the nature of spectrum and the nature of property rights. Every property right is a government construct--there are no such things as "rights" in the statute of nature.[1] As far as property rights go, spectrum is much more like land than it is like information. A property right in land isn't just ownership of the physical dirt--it's ownership of a particular piece of a finite coordinate space. Similarly, spectrum rights are ownership of a particular piece of a different coordinate space (the tuple (x, y, z, f)).

People can read multiple copies of a book without interfering with each other, but people can't transmit on the same frequencies without doing so, just as they can't farm the same land without interfering with each other.[2]

> The real free market answer is that electromagnetic radiation is information, and you can generate whatever frequency of it you want, and you assume the markets would naturally orient themselves to not interfere devices.

That's like saying that the real free market answer is to not enforce rights in land, and let the free market work out how to coordinate various uses of land so they don't interference with each other. There is a name for that, it's called the tragedy of the commons.

[1] A "right" deconstructed, just means some legal relationship which the government will enforce on your behalf through violence. Without government, there is no one to enforce rights, and the concept is utterly meaningless. A deer can't invoke its "right to life" when a wolf kills and eats it.

[2] This is an imperfect analogy for various reasons, but more or less true at a very coarse level of granularity.
It's not just poor people. There is an institution of ritualized ignorance-pride in protestant, typically southern, rural communities. In some regions (inner rural, southern), this "trend" is not a trend, it is a virulent norm. Wealth isn't the only factor here.

I see BitCoin as an opening gambit not an end position. It's likely that BitCoin will bubble, froth, and ultimately collapse, but that it will be replaced by something of similar form with certain structural improvements.

I read (wish I could link to give credit to the commenter) a nice analogy today - of BitCoin being the Napster of the space, innovator but not the ultimate winner.

Krugman's point as to its necessity is valid, however I still see it as likely that we'll end up with a currency of consensus, which has exchange value because a critical mass of people believe in its value and are prepared to act on that for a sustained period of time.

Note that I said start with those projects, and not end with them. Of course it would take more work to get in the same category of relevance as Google. But the point was that a significant portion of the code needed to build an "open source search engine" exists. But, even if it all existed, the problem would still be hardware and bandwidth. You can't easily build a Google-like without some serious financial backing, even if everything is open source.
I believe you are correct. Otherwise you could only import each package once during the whole project, right?

At first sight it may be useless (in this form anyway) but I've read that people tend to spend more by having credit cards because you don't have a physical reminder of how much money you have left, it is just a digital number. I'm predicting that in the future we will have solutions to bring back some physical stimuli to our digital transactions.

So, this might be naive, but for static information like the shared libs it's using, you might want to check out otool, and then pick up a good disassembler (I'm a fan of hopper, which is relatively cheap). For dynamic analysis you might want to check out the standard osx tools like netstat, and instrumentation tools like valgrind or gdb. gdb + breakpoints on choice system calls works pretty well on non-obfuscated binaries!

No, what seems like a massive waste of our educational system is the notion that Federal tax dollars are going toward the higher education of non-citizens at the same time that millions of Americans either can't afford to go to school or are groaning under the weight of student debts. Odd that you should have missed that.
True, but what do you do with that data? Transfer it out of process? Analyze it? And how many systems can withstand that sort of slowdown without timeouts?

Performance counters can tell you quite a bit, and they cost very little to set up. Snapshots and a little differential analysis can get you more comprehend-able data without transfer/storage problems.
Yeah, I'm wondering how it might work if instead of using a sequence of byte configurations in memory it used a sequence of pixel configurations from the screen.

It seems like there would be an incentive for people to build radio jammers or other ways of generating interference. They would then use those jammers to extort legitimate broadcasters - pay me $1 million or I'll ruin your broadcast. Since the extortionist has equal rights to broadcast waves, broadcasting the interference is not illegal. How would you prevent this?

Radio broadcasts - ie electromagnetic radiation - is energy projected onto other's people's property. The libertarian view should be that it can limit person's A right to project energy if it interferes with the rights of person B. If I aim powerful lasers at my neighbors house, the government has the right to intervene. If I broadcast loud sound waves at 3AM, the government has the right to intervene. If I want to build a nuclear plant that might irradiate everyone in my town if things go wrong, the government has the right to regulate it. When I broadcast radio, I interfere with the ability of others to broadcast and listen to radio. The purpose of a government is to mediate these conflicts. Predictable mediation requires establishing clear ownership rights.

Maybe you could argue the government should have allowed spectrum to be homesteaded, rather than purchased, but the end result would be similar.

This is something I've been experimenting with. My intuition is that the scene graph will look a lot more like an AST made from algebraic data structures than an OOP actors network.

The hypocrisy of the New York Times in printing this is shocking. The newspaper which did so much to whip up hysteria during the years of the Bush administration now trying to raise concerns about the inmates of Guantanamo is shockingly cynical. It's a shameful state of affairs that our political process is so broken we cannot deal with this situation in a civilized fashion, with investigations, trials and an end result. Instead we live in an Orwellian state of perpetual war, one which the New York Times was happy to goad us into back in the days when they actually sold newspapers and profited from a nation's feelings of hurt and lust for vengeance.
To make sure we are on the same page, let me try to summarize: you are essentially saying that so long as people take into account negative externalities, rent seeking behavior goes away?
