Sorry, but your brain (~10^-1m) is way, way closer in size to the Sun (~10^9m) than it is to the Planck length (~10^-35m).

Never mind that, though... So you have a general solution to the n-body problem? I'm being facetious, of course. The hardness of the n-body problem isn't necessarily an expression of fundamental randomness rather than technical uncertainty. But one way or another, aren't they both an expression of the same thing?

Modeling an n-body system in the physical universe exactly means modeling every piece of information in the universe. If you don't do that, the unknowns will multiply into significant divergence at some t, however distant. Quantum theory suggests that even if you did have a computer the size of the universe that didn't affect the universe, it is intrinsically impossible to make an accurate prediction.

I can't know where a particle will be in a second, or even if it will exist at all. I can't know if the Earth will be hit by an asteroid in a hundred years. I can't know who will win the Presidential election next year. The more accurately I model these systems, the more their outcome (or rather the outcome of the abstract macro-system of which I become aware) becomes dependent on the few things I don't know-- to the point that simply the act of checking the accuracy of the prediction has an unpredictable effect.

At that point, it seems like splitting hairs to say "Yes, but it's still really deterministic." What "real" are you talking about? Certainly none that I have experience with. But that doesn't matter either, because even granting that:

The universe might be deterministic, and it might be nondeterministic. It's unpredictable. So how does determinism become the default?

Subscription music services are my preferred way of consuming music. I had a Zune subscription for over two years (eventually cancelled when I lost my Zune and just started using my iPhone... Zune's big weakness was its hardware exclusivity), and I signed up for Spotify premium as soon as I could. I like sub models because I am paying for music, I can get whatever music I want (almost... bands like Arcade FIre don't license their music to these services I've found) whenever I want, and the actual data is well-manicured in terms of metadata.

If you read any merchant agreement for credit card companies, you will see that you are technically not allowed to charge someone until you ship a product.

Charging someone before you have actually "delivered" the good is a completely different level of risk than charging someone for something you've already delivered. The supplier might not ship, the manufacturer might not ship, or you could be outright scamming people.

This is not a defense of PayPal, but just explaining why money processors do not typically allow you to get your money for pre-orders. There's a huge risk that it blows up in their faces.

War has certainly touched the U.S. youth as we've seen massive internal shifts on personal liberty (e.g. TSA, security guards in school, signs in public transport that ask you to monitor your fellow citizens). The youth is also clearly able to see that the U.S. spends a disproportionate amount on the military rather than enriching it's own culture and people's lives. Much like the Occupy Wallstreet movement I would expect to see a call, by the upcoming generation, to demand that their birthright is not continued to be sucked dry by the military.

Spike Jonze's short film "Scenes from the suburbs" is an insightful example of how we might imagine a further deepening militarization of the U.S. Sadly it does not seem so far fetched to me.

Warren Buffett definitely is one of the greatest investors of all time, but it's a myth that he was a aw-shucks buy-and-hold-forever investor. Just like how complex Berkeshire Hathaway is, the actual From an article:

"Buffett likes for you to think that he just picks up an SEC filing, makes a phone call and seals the deal before he purchases a stock (and Wall Street wants you to think this as well), but Buffett is far more savvy than he leads on. This is exemplified by the complexity of Berkshire Hathaway. Berkshire Hathaway isn’t just your average insurance company. The brilliance behind Buffett’s investment in Berkshire is astounding. He effectively used (and uses) Berkshire as the world’s largest option writing house. The premiums and cash flow from his insurance business created dividends that he could invest in other businesses. But Buffett wasn’t just buying Coca-Cola and Geico as many have been led to believe. Buffett was placing some (short-term AND long-term) complex bets in derivatives markets, options markets, and bond markets. The myth that Buffett is a pure value investor is just that. And it has been fed to the public hook line and sinker by people who entirely fail to understand Buffett’s genius, but benefit from an investing public that continues to pour money into the “hold and hope” myth."

My comment on another forum where ESR's post was discussed (complete with inadvertent but funny typo), which explains why I think ESR (and RMS) just don't get it:

James Gosling has an interesting take on Jobs being a "control freak":

He was famously difficult to work for and
unrelentingly demanding of perfection. I
interviewed for jobs with him 3 times: once before
he was fired, once at NeXT and once after he
returned. Each was a long lunch at The Good Earth.
Each was a wonderful, intriguing conversation, but
I left each thinking, ‘No, I can’t work for
this man: he’s mad!’ That visionary madness
drove him and his company with a tremendous force.
He was personally not an engineer or a designer,
but he had a tremendous sense for excellence. Many
companies use ‘focus groups’ to help them
refine products, but not Apple: they just had
Steve. He was often criticized for being a
‘control freak,’ but that was all in pursuit
of excellence: anything out of his control was out
of his ability to improve. He didn’t just have
a sense for Apple’s products, he had a sense for
Apple’s customers and what would delight them.
As much as he was devoted to Apple, he was more
devoted to Apple’s customers. One of the biggest
drivers of Apple’s success in recent years is
the delight their customers feel in every part of
the process, even something as simple as opening a
box is thought through carefully. Every detail
matters.

The thing that really stood out in the giant collection of comments that have been published about Jobs over the last 3 days by almost everyone of any importance in the tech world is how many of these people were positively influenced by him.

This includes some of Jobs and Apple's strongest competitors--for instance when Larry Page took over as Google CEO in April, he says that Jobs reached out to give him advice and knowledge to be CEO even though Jobs was very sick by then. Note that this is well after Apple and Google had become fierce rivals in mobile.

That's how things work in Silicon Valley. Companies can be bitter rivals, but the people that run them can be friends and help each other. Business and people are separate.

What I find sad about the comments of RMS and ESR is that they are so one dimensional. They view people like they are in comic books--they must either be heroes who are good all the time, or villains who constantly plot evil from their secret volcano lair while stoking a cat. Real life humans aren't like that.

Is there a layman-readable proof or proof-sketch of the reduction from Group Isomorphism to Graph Isomorphism? Is the method constructive, so that every group reduces to a corresponding graph in an understandable way?

I have a somewhat cranky reason for asking. In evolutionary algorithms, a mutation operator is one which transforms an existing genome into a single new one. One can study the behaviour of an operator by drawing an edge from old to new genomes, for every possible genome, and studying the resulting graph. A crossover operator takes two parent genomes to produce a new one. No-one really has a satisfactory method of studying crossover analogous to that for mutation. The problem is we need edges to lead from pairs of nodes to single nodes. So kind of like hyperedges but not exactly. I've been hoping for a while that there is an answer in existing graph theory.

Crossover is also kind of like a group operation, but again not exactly. So that's why the idea of mapping a group to a graph is interesting.

I personally never even made the turtles connection and assumed that, since they are drawing libraries, they are surely referring to the artists.
I stayed at a hotel, but I can't remember its name. I was there with my girlfriend and we paid around $10 per night including a light breakfast. There are also some really nice resorts there, but I don't know how much they cost. The food is amazing and nasi goreng (fried rice with some meat and vegetables) is often not more than $0.40–$0.50.

Another thing: It's really easy to pick up some Indonesian phrases since the language is quite simple to pronounce and has a really simple grammar. The language does not have the concept of tones that other south-east Asian languages (Thai/Vietnamese/Chinese...) have, so even if the pronunciation is a bit off, people will understand you. It was really nice being able to use some polite phrases in Indonesian after just a few days – even if using English was no problem. :-)

Why does the official Python development still take part in CPython rather than PyPy? Is there anything seriously wrong with PyPy, so it can't replace CPython by now?
"Hacking" airports is especially useful due to certain airport layouts. #1 rule about standing in line: everyone just stands in line without understanding why they are standing in line.

For instance, in Philadelphia, the airport security is outside of the inner walkway which connects terminals D & E. E was the international terminal, so there was always way less traffic going in/out of the gate. Sometimes D would have a security line backed up to the curb. Simply walk over to terminal E and bypass the entire line.

Similarly, in LaGuardia, there are two taxi lines outside the American terminal. One is all the way at the end, hidden from sight. Everyone not familiar with the airport just lines up at the main one and if you walk around the edge of the terminal you can hop in a taxi right away.

Anyone seriously optimizing their travel, though, will most likely be a loyalty member of some airline alliance and the goal is to maximize your upgrades (free or otherwise) to always fly business/first.

For example, AA has a "challenge" where you can automatically earn Platinum status if you earn 10,000 points in 90 days. This isn't terribly difficult if you're flying to an international conference. You quite literally call a 1-800 number and say "I want to take the challenge." Platinum gives you automatic domestic business class upgrades when available!
Wow. I do not get the same conclusion.

For me, if I'm browsing via my phone or tablet, I'm in a completely different mindset than when I'm at the computer. See, the computer has a ton of things going on, and I'm usually trying to get something done with it.

The tablet/phone, on the other hand, is purely for entertainment. If I'm using that, I'm there to explore and browse. And that's pretty much exactly what they're seeing on their site.
I am aware that the turtles are named after the artists.

If you'll note, even a cursory scan of the artist's wikipedia pages would indicate that Donatello is primarily remembered as a sculptor, and Raphael for his pencil and painted works.

My point is, save for being Renaissance artists, the two have nothing in common, except that they're both Italian, and both had Ninja Turtles named after them.

The ITA Matrix tool was ridiculously helpful when dealing with my old company's corporate travel agent. They would invariably put me on some horrible flight schedule unless I used Matrix to find the best route and just give them the flight numbers to book.

It also was great the one time I was 4 segments away from requalifying for platinum on AA and needed to make it up before the end of the year. That routing language is good when you need to stuff extra segments into a trip and have them be on a specific airline.

Turned out the cheapest route was to have me go to Omaha (by way of Chicago) where I met a friend for lunch in the airport cafeteria and then hopped right back on a plane home.

> Firstly the difference between the iPhone and any phone when it came out was phenomenal. It was 3-5 years ahead of any other phone. I am not exaggerating at all. It was incredible, a true game changer

Yup. Before the iPhone, phone features fell into four categories:

1. I can figure out how to use this on my own.

2. I need to read the manual to figure this out, but I'll probably remember enough to be able to do it without the manual after that.

3. I can make this work if I have the manual with me, but probably will never be able to use it well without the manual.

4. I can't figure this out, and the manual makes no damn sense.

On many phones, even telephone features like conference calling where in #2 or #3.

With the iPhone, most things were in #1, including calling features like conference calling. Forget about the smart phone features--the iPhone was my first cell phone where I could actually use all the telephone features.

Going back to pre-iPhone phones would be as painful as giving up my calculator for a slide rule, or giving up vim for ed.
Your problem with downvotes is yours, if you don't want to risk being downvoted you should probably not comment here. It happens. This 'not being reddit' (or slashdot for that matter) has nothing to do with it.

Downvotes are a way to push non-relevant comments to the bottom of the discussion. And I really believe this ninja turtles stuff is a waste of space, I frankly don't have any desire to see stuff like that on HN.

As for my point, I think enough bits and unique ids have been wasted explaining it, if you wish to hold on to your position that the ninja turtles are the first thing that comes to mind when you hear Donatello that is entirely your problem.

These 12 points seem to be the most insignificant things you can think about your code. Indentation? Camel case? Come on... mastering WRITING code will not make you a good coder. It will make your code consistent, I'll concede, but there's nothing stopping your from writing consistently bad code that looks good. Wouldn't it be more fruitful to think things like: 1) Why did I write this code as one function? 2) Should I not write this query in a loop? 3) How much memory will this array take to store? 4) Will I understand this code 3 months from now? 5) Is this code readable without comments 6) Would commenting this block help the reader understand my intentions? 7) Should this be a class, and if so, how complex will it be? 8) Can I make this code reusable?

I was tweeting the other day that we now live in a world where the president of the United States can, without judicial review, assassinate with robots an American Citizen living abroad because of their speech and influence on terrorists.

Sounded crazy -- "death by robots" -- but that's about where we are (I don't differentiate between remote-operated vehicles and fully autonomous vehicles because it's not germane) We can't and won't torture a guy we pick up with a rocket launcher in his hand getting ready to kill us, but we can push a button and whack somebody who hangs out with really bad people. Don't forget collateral damage. And we call this morality.

Telemetry and robotics are going to change the world in wildly dramatic ways over the next 50 years. Places like HN are where somewhat knowledgeable people can kick around these ideas now, before everybody and his NGO have their own killer robots.
I have to admit, I was also slightly irritated when I actually checked out the repo. The title is deceptive.
