Sartre described this on a more abstract level in his essay "La transcendence de l'ego: Esquisse d'une description phénomenologique"[0], which essentially says that the active level of consciousness can never be reflected upon because the moment we reflect upon it it becomes passive, being reflected upon by a higher level of consciousness.

The amount of trading done by machines decreases as your investing timeframe increases.

So at the extreme (high frequency trading), all trading is indeed done by machines.
I think the problem with space elevators are not as much with the materials but with the logistics of deploying that. How do you get the cable up there? You can't just shoot up a rocket with a cable attached and expect the cable to stay upright: it would fall down unless you give it horizontal speed. But if you do that, you'd probably end up orbiting the Earth and tying it up with the cable.

The other option would be dropping the cable down, but you'd probably end up with a similar problem. I'm no physicist, but I'm pretty sure that dropping that amount of mass would shift the center of mass of the satellite-cable system and mess with the orbit.

Even if you manage to deploy the cable, you'd still have the problem of the counterweight. I've read that proposed solutions include a captured asteroid (we've just been able to land - or crash, depending on how you see it - in one), a space station/spaceport (that's definitely not cheap), an extended cable (which probably would require even more complex materials) or junk from the construction (still the same problem).

And we still haven't got to the point of security. How do you keep things (space junk, satellites, meteors) from hitting the cable? What would we do if several kilometers of ultra-strong cable fell down into the earth?

I think that space elevators are a nice fantasy, and just that. When we have mature enough materials and geopolitics, we'd probably be better off using them on other methods that seem to be far more viable.
Would you happen to know some good reads (either on- or off-line) for someone interested in computer trading with a technical background (currently doing a Msc. In Computational Science != Computer Science)?

I have been interested in doing a bit of electronic trading as a hobby (and hopefully a small profit, but I know better than to hope for now) and possibly a back-up career path. But while I've found enough information about trading in general I found it rather hard to find anything dealing with automated trading specifically beyond very simple models.
So who is picking up one aspect of the complex relationship here? If I get together with an AI in the future you'll call it marriage too?
Same sex marriage is still not legal in NI, so you're not quite right for "UK". And gay people were only allowed to marry in 2014.

The UK does better than most countries for supporting LGBT rights, but it took a long time. The UK discriminated against homosexuals for many years, and we still have some way to go to fully recognising rights of LGBT people.
I could see cases where this could be relevant. Imagine someone with a great career path in, say, SFBA -- forward and upward progression. In 2006 he quits a job after 6mo and moves to Houston, Boston, Rochester MN, etc. and takes a much lower job (say IT manager or something remote, and with flexible hours..,or maybe no job at all for a couple years) for 0-5y, and is now looking for a job again, based on the previous experience.

Maybe he got fired from the good jobs and couldn't get a job somewhere good again and had to move somewhere cheaper to take a job more readily available. Maybe he or a family member had cancer and wanted to be near the world's best particular cancer care. I'd probably be a lot more strongly biased to hire the person who was willing to sacrifice his career for a while to save someone's life than otherwise.

Here's a program:

int main(int argc, char* argv[]) {
double x = 0.75;
double t1 = 0.50000025;
int i, j;
int n8 = 93 * 100;
for (i = 0;; i++) {
for (j = 0; j<n8; j++)
x = sqrt(exp(log(x) / t1));
printf("%d %f\n", i, x);
}
}

Watch what happens to the performance as i passes 4632.

If you want to train neural nets, you can either rewrite everything from scratch and get a bug-ridden sub-optimal implementation, or you can use a kind of off-the-shelf library.

The problem is that there are about 3-5 alternatives out there, and none of them are mature enough or convincing enough to dominate. The field changes so fast that it's easy for them to become obsolete.

What you're seeing here is the enthusiasm of people who really want to get a good tool with proper support, and be able to stick with it. I'm still not sure if TensorFlow is that tool, but it depends on what will happen to it during the coming years.
I actually think a lot of Americans would be surprised how much people in other countries know about the US.

For example, a significant portion of Americans probably know basically nothing about France, and French government. France doesn't really affect their lives at all, and the mainstream news only mentions the country when a really major story happens.

But glancing at the front page of the Le Monde website, I see a story about Obama meeting with Netanyahu, a really interesting article about big data in American elections (with a lot about a tool called NationBuilder that I've never heard of), a blog about the search for extraterrestrial life that draws mainly from American research, and an article about Obama and Keystone XL.

There's a "Pixels" section full of American culture, with stuff about Fallout 4, YouTube stars, Microsoft, and an FBI hacking story.

A lot of this stuff could be considered "local" news; I'm not sure why anyone in France would care about Keystone XL.

Now obviously French people aren't walking around worrying about America, but in general, I think people in other countries know a lot more about us than we know about them. And that's not just because of the stereotypical ignorant American, the US just influences other countries more than they influence us.

it is a free web solution.
it is possible to organize both by folders and tags (properties/relations) and then search by keywords with respect to properties and relations.

any info can be shared or private. you may search through all users or a specific user. you may filter out which group of users to search inside or skip.

however it requires google account and no attachments now, it is possible to use google drive for your files and put links to gd into the system.
In addition to an algorithm not having all available information on the market there is also the fact that any niche or inefficiency in the market can be duplicated by others until it is negated.

If you discovered that the market always goes up on Tuesday and drops on Wednesday that only works until everyone else discovers the same thing and starts selling on Tuesday and buying on Wednesday.

I've often wondered this. I find columnar alignment of key:value pairs (in CSS, dictionaries, etc) to be much easier to read, but I find that I'm an outlier because most people get upset when they see whitespace changes in a diff. (FWIW, `?w=0` will hide whitespace changes on GitHub).

It would be rad if an editor like Sublime or Atom understood columns and displayed code that way without needing to reindent everything in the file every time you add a longer key.
Ask HN: Why do IP geolocation services charge for commercial use?
The geolocation datasets are publicly available from MaxMind and the cost of performing and delivering a lookup result is trivial in terms of CPU and bandwidth - even less so if the result is cached. So how exactly is charging for these services profitable if one can simply set up their own private geolocation server for minimal cost?

It is quite well understood that outside of plans like Mars Direct and Semi-direct, interplanetary and interstellar travel will require other technologies such as novel electric and nuclear drives, but we are simply not at a point where that is an issue yet.[1][2]

Even the ones that are, are basically a poker game between at least two intelligences, and AI is notoriously not that good at poker. There are plenty of stories about human vs AI poker players to google for where the AI either loses miserably or under weirdly limited circumstances merely loses significantly.

The computers do beat human when the game is intentionally played too fast for humans to physically / biochemically keep up (HFT) and humans usually destroy algos for long term (admitted or not insider trading or line of business expertise). The only really interesting timescale is the daytrader/poker player.
You mistake that I don't agree with you about how it should be. I just think we should deal with how it is and manage the chaotic system.
The reason all these things are glued together into one deal is that they will not pass on their own, because international trade is not symmetrical.

Consider a wealthy post-industrial nation A trading with a poor industrial nation B. Raw materials and simple goods flow from B to A, so tariffs will be the primary concern. Capital, complex goods, services, and IP flow from A to B, so investment, IP, and regulatory issues will be of concern in that direction. A tariffs-only deal will not be balanced and therefore not succeed. Likewise a regulations-only deal.

Trade issues are not even balanced between industries. A tariffs-dropping deal will find support from manufacturers, but opposition from materials companies.

So to succeed, a trade deal must balance the various interests of many stakeholders. That means gluing a bunch of stuff together so that to any given person, some parts will look good and some parts will look bad.

The reason Congress created fast track is that different people will see different parts as good and bad. Fast track ensures a simple vote on the balance as a whole. If enough people see more good than bad--overall--it passes.

A trade deal will never look ideal to anyone. The question is whether it's a net gain for most.

No it isn't. Marriage was adopted by the Church and redefined along the lines you describe - it existed long before that as a legal process to control inheritance.

Liberal generally means in support of gay marriage. I'm a member of a liberal church and we're very much in support of it.

The beautiful thing about the Church of England is that it includes a wide spectrum of opinion and tradition, from high church (smells'n'bells) to scruffy low church, from liberal to conservative, left and right).

I don't agree with everything, but it's a great space for people with different backgrounds and opinion to mix and learn from each other. It can be very radical in a quiet, British, socks-and-sandals sort of way.

TAG Heuer, Google Release First Swiss Luxury Smartwatch
I do the remote-thing from Louisville, KY. There has never been a moment that I feel like I'm missing out on the non-business benefits. I've gone to more concerts, plays, excellent restaurants, operas here than I've ever gone when I was living in one of the trendy coastal cities. This is directly related to having more disposable income.

Networking opportunities are less, certainly. There are plenty seminars, workshops, and what have you to keep up technically, but there are no big name companies or famous practitioners around. Few SW engineering companies, but decent amount of industries requiring developers.

There is undoubtedly a trade-off, but I am not wholly convinced that choosing the high cost/high opportunity trade-off is necessarily the best one. Personally, I felt like I drank the kool-aid a little too much when living in Sodosopa.
Welp, I know what I'm doing this weekend. This sounds like fun.
A fun mental exercise: What would it look like for something to be completely original? What could be made that would be completely immune to the charge of "not being original"? And would it have any value?
The graph isn't just a divisibility test, it reports the remainder after division by seven. I specifically acknowledged that this error won't mutate a "divisible by 7" result into "not divisible by 7" (because any number that is divisible by seven will still be divisible by seven after multiplying it by ten), but in every other case it will give you the wrong answer. (e.g. "remainder 2" will mutate into "remainder 6".)
I've been in the market for over a decade, and here's my take:

- Lack of sophistication. "Classically" trained finance people don't know much about computers. I took a finance class at a top business school, and it's nothing compared to Engineering. A bit of time-value-of-money and maybe some option math, but really it doesn't come close to the sophistication of a CS or Engineering course. I went to a meeting last week with a guy who wanted an automated trading system. He hadn't heard of Python. He didn't have any idea how to execute other than on 3rd party programs (which of course use algos, but he was just providing the decisions).

- Lack of scale. There's a lot of family offices who have a few tens to hundreds of millions of dollars. If they wanted an algo trading guy, they'd have to pay him a lot of money, you'd want more than one, and you'd need infrastructure. Plus there's the risk you get all this, hire the guys, and their results are no better than random. A lot of small fortunes like this tend to spend more time in tech-soft areas, like private equity or private debt. The stock trades are an afterthought that they can't spend much resource on.

- Two kinds of decision making: arbitrage and investment. The put it bluntly, arbitrage is easy to mechanize. If some guy quotes some options at the wrong value, it's obvious you want to trade with him. There's looser arbs (things that sort of always come back to normal), but the principle is the same. In some sense, it's not a financial challenge, it's a technological one. For investment (I think XYZ corp will go up), you need to have a sense of what risk you want to take. Utility functions are not easy to put into code. You can try, but you end up with situations where you decide not to have the algo on. There's also the principal-agent problem; most traders are agents, they need to look good to their boss. They need to be able to explain why they are betting on some company. Often, more effort goes into how to justify your trades than what trades to do.

- Things that can't go into a machine: I worked with a guy who used to go meet the CEOs, look them in the eye, and ask them if they'd make money. Now I'm not saying this approach works, but if this is your investment edge, how are you ever going to put that in a machine?

- Insider information: taking this in the loose sense, not the criminal one. If you're highly dependent on understanding some part of the market better than others, you may be better off talking and networking rather than coding. Goldmans are great at this. Every time you meet them, they offer a bit of info in exchange for yours. It lets them see things like the mortgage bubble before it happens, whereas a model would probably have issues due to the small amount of computerized data.
