>On the other hand, cutting expenses (as you seemed to be suggesting in another comment) is not the solution either. Remember how we got in this mess in the first place:

Depends what you mean by 'this mess' if this mess is a high level of debt without the productive economic activities to service it, I'd suggest that it was by spending too much on things that didn't provide a return on investment.

>They will effectively create the money –fractional reserve banking and such.

No, that is not fractional reserve banking, in fact what would happen if they did just print more money? Lets pretend they could do it without breaking away from the euro. Inflation would rise sharply? Would that lead to a better economic situation? Some people say it does, hence the UKs policy on QE.

>If we had borrowed from our central bank instead of Rothschild&co, our current debt would have been only 20% of what it is now –well, assuming we didn't borrow even more.

That is just a gross oversimplification, and really Rothschild&co? What are we, angry I learnt economics from youtube socialists?

>start borrowing from the central banks at nearly 0% instead.

Historically, this action hasn't worked well. Ultimately they have debt obligations as is, they need to settle that with something, where would that something come from? They could deflate the debt, which would be the effect of creating a synthetic entity which would loan at 0%. To deflate this much debt would seriously hurt people. They could potentially try and bond default, Russia kinda got away with it (some people say it was a good idea), but then Argentina really showed the problems that can happen doing this.

This is why people come down to taxation and spending, ultimately they are the only options, because any kind of inflationary policy is a cruel tax, as it is often felt more by the poorest, due to the commodities which tend to rise. Meanwhile the super rich can make money of the back of it and even increase their worth leveraged thanks to the inflation bonds and the like.

In Go it is straight-forward to call assembly or C code, so it is well possible to implement projects that need low-level functions. In particular it is no magic to manually allocate memory and handle all memory yourself.

Are there actually popular GC implementations that don't use any assembly?

It would be nice to take a common gadget, say an iPhone or an Android phone, and split it up into small bits and pieces (including software) and then list all the pieces which are based upon a theory or research which decades ago was considered irrelevant and useless. I.e. all the findings which make up an iPhone, but where decades ago people would have said 'what does this add to our life'. What I can think of, right now, is

- Cryptography (iCloud, iMessage, Online Banking): Is all based on prime numbers. For hundreds of years, prime number theory in math was considered a purely academic exercise, something with no real world usage at all. And suddenly it is the basis of many things we consider granted. [1]

Curiosity. With this 130 page research paper, I'm really curious what's its application in the near future. I'm sure there will be, I'm seeing this in the branch of cryptography.

I'm imagining it to be implemented like a public-private key. Maybe the odd number can be the private key. And three prime numbers can be the public keys. The hash can't be decoded by just the single public key. It needs all three of the public key to decode the hash. Well, with just abrupt thinking, I think it can be more secure? (Not really sure about it though. Just a guess.)
Pure mathematics has a habit of trickling down to real world applications.

Sometimes that influence is direct, as seen with cryptography. In fact much of the worlds security is based on prime numbers. eg HTTPS (SSL / TLS) uses RSA.

Sometimes that influence is indirect. Such as math theorems that are applied to physics. Which in turn lead to real world products (eg faster processors, GPS, etc).
Than you so much for this. You actually implemented Haskell/Caml for us, mere mortals, and as close to bare metal as possible. Bravo!
Thanks for the "wisdom" but I've done my research already. There is no consensus on the web that threaded is hands down the best way to do it. Some prefer flat some prefer threaded. I'm just building flat++, fixing the worst problems.

There is plenty of evidence that the battle between these two isn't won. On the full threading side: Reddit, HN, Slashdot, Disqus, LiveFyre. On the flat (or 1 level nesting) side: Branch, Google+, Facebook, Discourse (http://www.codinghorror.com/blog/2006/11/discussions-flat-or...), Vanilla Forums, etc. Seems like a fair fight to me.

Without having looked at this implementation (but I know a startup doing something similar for an internal system): You add a suitably sized "buffer". So e.g. if your maximum stroke width is 20, you clip the polygon with an accordingly large margin. There are still potential caveats, e.g. if you want to allow changing automated label placement based on shapes etc., but the potential win is still massive even if you have to put some minor restrictions on what type of restyling can be done without having to "re-render" into vector tiles - this way at least most typical restyling such as changing colours or stroke widths can be done trivially.
The most famous quote for this is by G. H. Hardy, a famous number theorist. He said:

"No one has yet discovered any warlike purpose to be served by the theory of numbers or relativity, and it seems unlikely that anyone will do so for many years."

Yet here we are a few decades later with the fundamentals of modern cryptography based on number theory results. Specifically, the difficult in factorizing the product of two primes into the original prime factors (RSA).

So while this specific might seem abstract and without purpose, it often goes in mathematics that we'll find the purpose for it later.

I'd recommend A Mathematician's Apology for a defense of number theory by someone who was quite prominent in the field. It's slightly dated ("No one has yet discovered any warlike purpose to be served by the theory of numbers or relativity, and it seems unlikely that anyone will do so for many years."), but a lot of it is still relevant, or at very least, interesting.

I think there's a defensible case that in the case of Saudi Arabia, there are other parties operating in the country who are much worse for the rights of both Saudi citizens and humans elsewhere, and selling the digital equivalent of arms to the Saudi Government isn't inherently evil.

I'd sure rather deal with the current Saudi Government than with Al Qaeda. Yes, there are fairly bad elements within the government, and it is at best one of the more restrictive regimes in the world, but there are some alternatives that are worse.
Yeah, civil liberties and equal rights are all hype.

Knowing More Programming Languages Will Make You Smarter
Wikipedia has a good summary of the risks:

http://en.wikipedia.org/wiki/BRCA_mutation

A 25-year-old woman with no mutation in her BRCA genes has an 84% probability to reach at least the age of 70.[16] Of those not surviving, 11% die from either breast or ovarian cancer, and 89% from other causes.

Compared to that, a woman with a high-risk BRCA1 mutation, if she had breast cancer screening but no prophylactic medical or surgical intervention, would have only 59% chance to reach age 70, twenty-five percentage points lower than normal. Of those women not surviving, 26% would die of breast cancer, 46% ovarian cancer, and 28% other causes.[16]

Women with high-risk BRCA2 mutations, with screening but with no prophylactic medical or surgical intervention, would have only 75% chance to reach age 70, nine percentage points lower than normal. Of those not surviving, 21% would die of breast cancer, 25% ovarian cancer and 54% other causes.[16]
The likelihood of surviving to at least age 70 can be improved by several medical interventions, notably prophylactic mastectomy and oophorectomy.[16]

The C philosophy is captured in http://www.open-std.org/jtc1/sc22/wg14/www/C99RationaleV5.10...

"Some of the facets of the spirit of C
can be summarized in phrases like:

• Trust the programmer.

• Don’t prevent the programmer from doing what needs to be done.

• Keep the language small and simple.

• Provide only one way to do an operation.

• Make it fast, even if it is not guaranteed to be portable. "
I think more importantly it brings up the very real human implications of the debate against patenting human genes, which has most recently been centered around the BRCA gene.

Well, he's mistaken if what he is saying is what you think he is saying, but I think his statement is ambiguous.

I think he might mean when he says the gap does not grow unbounded is that that you never reach a point where the gaps are ALL arbitrarily large. As we run through the primes, we'll always continue to find gaps that are 70 million or less.
I'm wasn't talking about second level domains (though you're right that -where available- second level domains do widen the scope for TLD usage). But what I meant was that ICANN periodically releases new gTLDs for public use and even offers a program for companies to sponsor new gTLDs.

With regards to .io, technically that's a country code (ccTLD) that's been re-purposed as a gTLD by many organisations in recent years.

I don't see such an application; given a number which is known to be a sum of primes it's very easy to reverse this and extract the primes (unlike multiplication, which is how RSA works). And for practical cryptography processes it's always been perfectly reasonable to assume the goldbach conjecture - even though there's no formal proof yet, it's true in such an overwhelming majority of cases that you really wouldn't worry about hitting a counterexample, the odds are far smaller than e.g. a hash collision.
Yeah, per type or with interface{}, where every function has to do run-time introspection.

I find it fascinating that just over a hundred years ago proactive teeth removal was a standard practice. Women would get all their teeth removed to save money for the prospective husband. And left untreated for too long, rotten teeth will definitely kill you through infection.

These days, women are getting proactive mastectomies, not so much because of the costs involved in treatment, but because cancer is a much scarier disease than teeth rot. At least to us. To us proactively removing your teeth is a bad joke.

In 100 to 150 years, will people think about a proactive mastectomy as a bad joke? I sure hope so.

You ask: 1. Is X good? How is it good? 2. Is it entirely separate from reality?

While you might think of it as a simple question, you asked it in the general sense, without any context. In the general sense, these are two central questions in 2 separate domains of philosophy. 1. Ethics/Moral Philosophy 2. Dualism (philosophy of mind). Neither has a simple answer, although you could start form Wikipedia or the Stanford Encyclopedia of Philosophy.

Furthermore, the idea and enterprise of science and math is complex. It's not familiar to the layman. Instead, try approaching the question with more familiar ideas:

Think of a person who doesn't use Facebook at all.
1. What does Facebook add to his life?
2. As far as he can see, Facebook is a purely virtual social network, isn't it?
3. Why is it worth everyone's time to check/use Facebook?

Think about it from the perspective of a non-Facebook user. Perhaps one of the tribesmen in Africa should you know any.
