I've seen some pretty scary numbers on the effect of 3-D Secure payments to conversion rates. I guess it's really hard to do The Right Thing™ on this matter.
I host a bunch of lower traffic static sites all on the same DigitalOcean droplet with nginx.
Taking the Cramer model, the probability that a number N is not expressible as the sum of two primes is

product(x=1...N-1) (1 - 1/log(x)log(N-x))

< product(x=1...N-1) (1 - 1/log(N))

= (1 - 1/log(N)) ^ (N-1)

Which is eventually below

(1 - 1/log(N)) ^ log(N) ^ sqrt(N)

Which converges to

(1/e) ^ sqrt(N)

And so is eventually below

(1/2) ^ sqrt(N)

The -log of the probability that a number is expressible as the sum of two Cramer numbers is thus at most

-log(1 - (1/2) ^ sqrt(N))

Which is eventually below

2 * (1/2) ^ sqrt(N)

You can show that this is a convergent series, and if the -log of the probability converges then the probability that ALL integers (minus perhaps the first few) have this property must converge, to something above zero. Thus, there is a nonzero chance that a set of Cramer numbers will have the property that all a finite number of positive integers will be expressible as the sum of two of them. Thus, prime numbers do not need any magical properties for some version of the Goldbach conjecture to be correct on them - the magical properties are only necessary to actually prove it.
To a large extent the primes appear to be distributed in a manner indistinguishable from randomly. There seems underneath to be no reason to believe that there are results like this. If they were random then there might be numbers that cannot be expressed as the sum of 3 primes, but somehow every number ends up so expressible.

I see this as backwards. Based on the prime number distribution we can actually predict the probability that a given number will be a counter example. And the sum over all positive integers of those probabilities is a miniscule number, so we're quite certain that the statement is true. We just don't know why.

The primes are distributed to a first approximation randomly with independent probabilities 1/log(n) for n being prime. You can refine this with obvious divisibility criteria. (For example odd numbers appear randomly prime with probability 2/log(n). And so on.)

If you first refine these statements for all the small primes that you care to, then make any prediction that you like, that prediction tends to hold up very well.

For example consider the even form of Goldbach's conjecture, which says that every even greater than 2 is the sum of 2 primes. Well, 4 is a special case, so it really is that every even greater than 4 is the sum of 2 odd primes. Does this seem unlikely?

If n is even, it is the sum of 2 smaller odd numbers in n/4 + O(1) ways. On average those have independent probabilities around 4/log(n/2)^2 of being the sum of 2 primes. Therefore it tends to be the sum of 2 primes in O(4n/log(n)2) ways, with the exact distribution being close to a Poisson distribution around the projected number, which for large n is well approximated by a normal distribution. (There are various minor quibbles and corrections that you can easily use to refine this basic prediction.) From this the probability of being a sum of two odd primes in 0 ways can be estimated, and turns out to go to 0 fast enough that we expect only a finite number of counter-examples. (2 and 4 are indeed counterexamples to the stronger statement, but we know of no others.)

This basic projection can be verified for small n by computer analysis, and indeed works out to be remarkably accurate. Therefore we have great confidence that Goldbach's conjecture is likely to be true, but absolutely no idea why.

The hope, some day, is to be able to close this gap. To not just make assertions based on known statistical facts about the distribution of primes, but to be able to prove them.

The best known example of a statement which should be true that we have not yet proven is the Riemann Hypothesis. It should be noted that Louis de Branges does claim to have proven it, nobody has investigated his claims depth, and he was right about the Bieberbach conjecture.

My favorite example of a statement which looks reasonable on the numerical evidence, cannot be supported by this kind of argument, which later proved false is Mertens conjecture.
>But we are still animals - our physical existence is, in the final analysis, the only one that actually matters.

Uhm, like I said - macho bullshit. There is not a single actual argument in that paragraph past "strength good weak bad".

People historically were as strong as they had to be; I have a pretty good intuition about this as I'm only about two generations removed from subsistence farming. It's not like you had the time - or often, the calories - to spend doing pointless exercise.

I care about feeling comfortable in my body. I'm sure being able to lift 300lbs makes you feel more confident! but I learned how to be confident a few years ago.

Do exercise because it makes you feel good, and because our bodies need a workout every now and then. Don't get caught up in some silly statistic; there's a diminishing ROI past a certain level of fitness (which, admittedly, I'm currently still far from attaining).
I suspect the person you're responding to understands this quite well; they are responding to someone that takes the next step to not caring:

[...] over time you just get used to it and don't care anymore.

That's fine for you but don't excuse it as part of the maturation process. That's bullshit. Some of us choose to take a more practical approach.
I have a secret about fitness to share. It's the reason there are so many snake oil programs out there. Everything works. For a sedentary person ANY random stimulus is going to give you a couple months of improvement.

The true measure of a program is if after the first year you are still making quantifiable improvements.

I'm not sure if I agree. There are many examples of science and math being developed to solve problems. Pasteur's Quadrant is an interesting book on the dual nature of science for the sake of science and science for the sake of applications.

For proof that there's a transparency problem, I'd want to look at hundreds of FOIA requests across 10-20 categories, content of news conferences and press conferences, level of press access to government officials, responsiveness to press inquiries, responsiveness to Congressional inquiries, and I could probably think of a few more things if I put more time into it. Then I'd want to compare that to data from previous administrations.

Good point. It's interesting to note that there's a specific named region of the overall southeast, known as the "I-85 Corridor"[1] where a lot of economic activity is centered.

That said, there's a lot more to the Southeast than manufacturing. NC, at least, has a vibrant tech-startup scene, particularly in the Triangle (Raleigh / Durham / Chapel Hill) region. And, as the Wikipedia page notes, Charlotte is quite the banking / finance hub these days.

This area also largely overlaps with what is known as the Piedmont Atlantic Megaregion[2] which is acknowledged as an emerging area of substantial economic growth.

IOW, "this ain't your father's Southeast".

I feel the same way about iCloud. I know it is there and it backs up some of my data. I wouldn't be able to tell you which apps use iCloud and what data it is storing though. I don't think it is obvious enough to the end users, it is too transparent, which creates confusion and misunderstanding. I've given up on iCloud...
Intel fuses off x86-64 on some chips it sells for reasons of market segmentation.
I think the market is somewhat different in the US. My impression is that Whatsapp has a much smaller market penetration. I downloaded it to talk to one friend, only one other person in my 200+ contact phonebook had it.
Its a broken system when that does not happen. So, I agree with you, its a broken system.
Has coach sommer or any of his athletes been linked to PED scandals? I haven't heard of any, but it's possible.

Also, couldn't you say the same thing about professional weightlifters?

The pissing contest between weightlifting and other types of strength training is pretty ridiculous. As I said in one of my original comments, both methods are completely viable. Whether you use weights or bodyweight exercise, a person who exercises is going to be far better off than someone who doesn't.
This explains the lack of both decent housing and healthcare don't exist in the US. A country that cares so little about its citizens' human rights that it will publicly murder them is not a country that is likely to care about healthcare or housing.
Thanks, that's precisely the passage I was thinking of.
"Why are we doing this now? It's a statement of confidence."

Not desperation, but confidence. Riiiiiight.

Am I the only one who's not buying this?
Then you learn that all places are terrible and become an old grumpy man (in the scheme of life) like me.
I'd love to hear your sources about "all" the gymnasts who are on PEDs. I was a gymnast for 16 years, competed nationally for 10 years, personally knew and competed against some of the US team members in the 2008 and 2012 Olympics.

I have never, ever, heard even a whiff of anyone taking anything remotely on the wrong side of rules for "performance enhancing" substances.

Bodyweight workouts can be incredibly challenging and develop not just strength but explosive power. Regular pushups too easy? Try clapping pushups or handstand pushups or an iron cross to work your deltoids, pecs and triceps.

Your text editor and email client aren't also capable of running arbitrary applications. Modern web browsers have more in common with operating systems than with text editors and email clients.
I think a few things mainly answer your question about Europe:

- More social housing than the US

- Higher minimum wages (so fewer homeless)

- This is just a personal impression but Europeans are less mobile than Americans. Therefore there is more likely to be the family / friends safety net to catch you.

The GP wasn't saying heavy lifting is required for strength gains, he was making the much stronger claim that it was necessary to be healthy. (Perhaps unintentionally; I'm not sure they actually read the bloody linked article.)
41% of the population will experience a diagnosable mental illness, and 26% have one in any given year. Clearly there is more to the issue than just blaming mental illness or there would be far more homeless people than there are right now.

Discovering what support structures work and making those more easily accessible seems like a great place for a disruptive start up, except that health care is so incredibly messed up no one wants to touch it with a ten foot poll.
> When the super-rich have all the money, the super-rich drive up the cost of living.

For the sake of argument, let's assume that the super-rich spend the same or a similar proportion of their income on necessities as everyone else (meaning that they buy more food, more clothing, more housing, etc.). What does this do? It increases the demand for food, clothing, housing , etc. in the area. This is _not_ a bad thing. This means businesses in the area, if they are allowed to, will grow and new businesses can come into existence. For a real world example, look at Apple, for example. Apple employs 13,000 in Cupertino. However, Apple also indirectly creates 70,000 additional service jobs in the area through their direct employment. Are you saying this is a bad thing? This is much better multiplier than manufacturing.

The only issue we run into here is housing. If the area can't accommodate the increase in demand, housing prices will increase. This means owning a business will be more expensive, meaning the costs of everything will increase. This is what we're seeing in areas like SF.

But the thing is, this doesn't just have to be the super-rich who cause this. If you see an increase in demand for living in a specific area for any reason, a similar thing will happen as if a bunch of super-rich move into the area.

Further, the super-rich don't actually spend their money in the same way poor people do. They invest a good chunk of their money and they don't spend in the same proportion of their income on necessities, so they'll contribute far less to the increases in the cost of living than previously assumed.

So this entire argument of yours really doesn't make sense to me.

> It's a poverty spiral. Uneducated families just get more uneducated without state intervention

And this is a completely different topic and again I don't understand for what you're arguing. The government has had a monopoly on education for a long time and has gone to great lengths, in both primary and secondary schooling, to intervene. In many ways, this has driven up the cost of education and driven down the quality. But this is mostly a tangent.

> When are we going to wake up from this Randian dystopia we're creating??

I wouldn't call the Bay Area, in California, in the United States, a Randian dystopia. The amount of regulations and taxes one must deal with in this area is astounding. You even brought up the sad state of public education. How is this Randian in any way imaginable? You're on the wrong end of the spectrum.
That would be an expensive lesson, don't you think? Not only for the guilty but for the other drivers as well. I would go for low bars as supplemental safety measures.

That white clean look is going to start looking disgusting once it gets use in the real world. I see them imitating apple's design aesthetic, but they really should have learned from the white macbook - because this is going to be worse. Cash registers are already always dirty, because there's high transaction volume there - it's literally the bottleneck. Now it's white and pretty looking, so it'll draw your eye, which basically requires every business who gets the square stand to give it a good clean daily.
Physical strength is the most important thing in life.

What a load of shit. I was actually considering checking this guy's stuff out until you posted that.

It's a well-used sales line: You've got somebody on the hook- they obviously think it's important or they wouldn't be looking at the book. They also obviously don't have what you're selling, so they wouldn't know any better. Then, make an argument (emotional if possible) as to why they need this. Presto: sale. And perhaps guru status.

I imagine this works for similar "my life would be better if only..." sales. Penis enhancers come to mind.

I think the OP's workout is a great place to start. The only caveat is that you want to go through the routine several times as you get proficient. The exercises are part of the "core" exercises that serious athletes are doing. If you stick with it you can add yoga, bosu, and medicine balls to the mix to work on your stabilizing muscles. You can add dumbells and barbell exercises too. I added "core" to my workouts about a year ago and am please.
I'm really enjoying this thread. My idea of a good gym is one that has an espresso bar with delicious brownies and a fireplace.

However, my wife is both ACSM and NASM certified. She's spent the last decade "just doing the damn squats" and all the rest of her waking hours working with clients and studying, studying, studying.

I've been reading your replies out loud and she says, "Right on!"

And yeah, I'm a pretty lucky dude. :)

Inflation is the constraint, not solvency. We need to find the right number between 0 and 10^10 but we are not trying to do that and so we're becoming like Japan.
Fully with you - without that it's just charts (with hard-to-tell-apart colors).

Particularly as this is based on Inc.'s 500 list(s) - had a look at something similar a few years ago based on these lists - according to their data the fastest growing companies at that time (4-5 years ago) where all Human Resources / Head-hunter start-ups.

> is where do people live in Europe if they have no personal funds to buy or rent housing? Do they live in housing operated by some unit of government, or where?

The English benefit system is complex. Here's an attempt to describe some of it.

We pay a national insurance. Some of our benefits are based on contributions you make. Other benefits are income related (means-tested.)

If you have a mortgage and lose your job you get the interest on the mortgage paid, but not the capital.

If you're renting there's something called the Local Housing Allowance - that's a list of property types (one room; one bed; two bed; etc) and maximum prices for those properties. You get all your rent if you're under the limit, but you have to pay anything over the limit yourself. Actually, it's a lot more complicated than that. You cannot be "over accommodated" (more on this later, with the 'bedroom tax'). You cannot have savings over a certain amount (£16,000?). It has to be a real rental situation; renting off family becomes tricky. There are rules about living with people as if you're married, etc.

Housing benefit is paid by the local council, using money they get from central government. It's a horrifically inefficient system, and has a lot of fraud.

Then there's "social housing". This is provided by companies providing it, or by local councils. Council houses tend to be high quality buildings in not-good areas. Rents are very cheap. There are very long waiting lists. Recently there's something people are calling the bedroom tax - if you're in a house that has extra bedrooms the rent for those rooms is not paid. This has always been the case with private renting. There's a bunch of reasons why this is horrible, and those exceptions should be baked into the new law.

Some people need emergency accommodation. Local authorities should provide bread and breakfast accommodation, or hostel accommodation. There are pretty strict rules about what counts as "homeless". And if you're found to be 'intentionally homeless' it's going to be very hard to get help.

Apologies for the garbled text. It is a complex, large, bit of law with many overlapping bits of legislation.

If you discard huge parts of the population as worthless you'll have to invest even more in your security. You will have slums, riots, terrorism and violence and walled gardens.

OP is offering a possible partial solution to exactly the problem you present here. With fewer children born into poverty, some degree of abatement is likely. I'm not sure why you dismiss the notion out of hand, refuse to engage the actual idea, and then immediately mischaracterize the original position to be some absurd straw-man in which the OP is adjudicating the "worthless[ness]" of various people.

It's almost as if people on the internet don't know how to properly argue the actual ideas presented, and instead prefer to just make shit up.

It was very interesting. I first didn't realize it was Wolfram's blog. I was split by the tone of the post, which seemed to be comparing the author to Leibniz and which seemed to be a little pompous. It was an interesting bit of history about Leibniz at the end. I found the medal bit hilarious. Not quite as pompous, perhaps, a bit of harmless fun.

Anyhow, for math history buffs out there, if you go to Germany, drop by the Arithmeum in Bonn (http://www.arithmeum.uni-bonn.de/en/home/). It is a fun place to spend an afternoon.

Isn't a normal number ever so subtly different from that? In that not only does every possible sequence of data occur in the digits of a normal number, but each sequence occurs an infinite number of times with likelihood proportional to the number of digits.

Infinities always mix up my intuitions, though, so they might be equivalent.
I used to be a teaching fellow at NYU for iOS programming - what OP says about teaching to learn is absolutely true.

I don't think I'd be nearly as skilled or knowledgable about Objective-C, Cocoa, APIs, or mobile development generally if I didn't have to guide my students. The added benefit of my situation in particular was that each student worked in teams to get something pushed to the App Store - helping me figure out how to manage multiple "dev teams" at once.

If you want to get really skilled at something, teach it.
