Well...Elon has made guesses/estimates/given us lots of ideas about his monetization strategy. I think the most promising is to sell tickets at $500,000 apiece, which he thinks will be about the going market price to meet a demand of ~100,000 colonists.

Mars One thinks they can do it on a TV show (they'll fail, though, obviously).

My point is that your "nobody" comment is unfair and incorrect. Lots of intelligent, capable and experienced people have articulated a number of different business models around the colonization of Mars. None of them are proven, of course, but that will take time.

You've probably heard it as ones that lead to low-coupling and high-cohesion, which is correct. But in my experience this needs to be made more concrete -- many people can say these words, but couldn't tell you accurately to what degree a system was cohesive and uncoupled.
The information bandwidth in bytes/s is limited by the SNR and the bandwidth (in Hz) of the radio channel. The atmospheric "window" is only so large. At the same time, antenna's can only be so focused and transmit power is only so high. If you're interested in reading more about this look up "link budgets."
No it's not trolling. I just want to see if a human's workload on space missions can be replaced by a set of sensors and robots.

> Primarily, the reason to send humans is because we have to in order to ensure the continued survival of (known) life in the universe.

Sure, but why not send multiple robots and a bunch of sensors? Humans need food and water to live (don't know how much of the payload will be a year's worth of food/water), and are generally inefficient at converting food sources to energy.

> Humans have collectively agreed that it's worth 10,000+ annual deaths in the USA in exchange for the convenience of cars.

Wrong. This is why we need autonomous cars. Driving is best done by computers, and humans will agree that it is NOT worth 10k+ annual deaths a year just to give humans "the pleasure of driving".
Fuck the cynicism. The fact that NASA finally has its head turned around to at least announce is indicative to me of a cultural, maybe generational shift towards giving a shit about space travel. Who cares who does it first, at least this is a trend in the right direction.
In some way the assumption that the private sector can do it better is supported by NASA itself, it's why they have contracted missions to the ISS out to SpaceX and Orbital Sciences, who have managed to successfully fill those contracts for $500 million (less money than NASA was spending on a single space shuttle launch). I have tremendous respect for the work NASA has done, but there are deep flaws at the agency, and they realize it as much as everyone else does.

Weird, it's almost like yuri was the one peddling errant bullshit that h1bs were not about cost. So I see you saying that they are, well, exactly about cost. Glad we cleared that up. Whining that he can't operate profitably at market wages reinforces my point: h1bs are entirely about cost.

So perhaps he needs to offer a million dollars, if that's what it takes to get his perfect unicorn (minimum job requirements: 23 years experience with python. Cue whining that we have a talent shortage when Guido declines job offer.) But I'd bet he'd get a hell of a lot of interest at even 10% or 15% over the going wage.

All he wants is to sidestep US immigration law to undercut wages of domestic employees. There, was that so hard to admit?

Yes, he's too busy to recruit! Why aren't those uppity employees lining up begging to work for him? I mean, looking at employees on linkedin is, like, so much work!
I would also love to be able to move across instance families. Another reason not to commit for a long period of time.

One only need look at San Francisco's "little Italy", which is not in any sense an Italian neighborhood any more, except sort of for tourist purposes.

Well, that will differ from person to person. My personal incentive to go to Mars is that I want to study its atmosphere, help modify it to become denser and warmer, to be friendlier to life. Others will have different incentives to go, I imagine.

The topic of my senior thesis for my history degree was that history is the study of the world through metadata (in contrast to physicalism which says that science is the study of the world through data).

I used Wikipedia as an example since the prevailing wisdom is that you cannot use it as a primary source. I argued that the metadata such as the edit history and talk pages constituted a legitimate primary source. For instance, if we wanted to argue that a certain topic is controversial (e.g. the administration of George W. Bush), we could look at the velocity of edits (especially undos) and the discussion on the Talk page.

Why are those the core values? I can think of several off the top of my head that are more important. What makes America a better place to live than Bangladesh is not that we believe in hard work and independence while people in Bangladesh do not. Beliefs are a part of it, but not those specific beliefs.

I moved from the Midwest to the peninsula 3 years ago (for my wife's work). I made roughly those numbers there and here and the standard of living was roughly the same, maybe even dropped a little. Living in Silicon Valley is easily 2-3X more expensive than living in a place like Indianapolis or Columbus, OH.

You honestly don't feel these pressures as much until you're older and have a family. At least, the differences between the regions are much more apparent with a family. For example, we need a certain amount of living space, and there are a set of fixed expenses. We lived in about the same size homes here and there, and just the cost for that alone more than tripled.

Well you haven't paid a dime in NASA funding yet. All funding to date has been borrowed from people younger than you or not yet born. Presumably the gov't will borrow many times more to get to Mars, than it has for any previous mission.
That's not the issue at all. If you look at the historical budget of NASA[1] it has a very low correlation with Republican presidents[2].

The main issue is that they get a lot of misdirected funding that's mainly allocated as a function of short-term political interests, and that's an entirely bipartisan issue in the United States.

Nice! I made something similar to teach myself Qt. It took an image and turned it into an offset grid of circles. You could adjust the area of the image assigned to each cap to see how many caps you need to get something recognizable. Then it would spit out a listing of how many caps you need for each color.

Just a heads up: the number of caps needed to make a recognizable david tennant in front of the tardis is very high. Table size becomes an issue. :)
Adventure is kind of a selfish goal, considering that only one or two humans get to enjoy the experience. All those resources and manpower is a waste if the rest of humanity doesn't benefit from it.

Still this is far less simple than Google's "sustained use" discounts, where price automatically drops when I have more constant use pattern. Here I still need to plan upfront, assume my future usage patterns. It seems easier, but in fact you need to make the same decisions as previously.

The article talks about hidden markov modelling, which combined with initial training data, can theoretically be applied to your cipher to solve for a solution. The number of things that humans can observe and create sensible (memorable) code from is not infinite. It must be based on some aspect of the environment from which information is derived. You get the abstract form (the grammar) and train to infer the patterns of how substituted words are selected.

Then, what will happen is language will cease to make sense as the complexity to communicate secretly increases. The real targets will communicate using literal forms of encryption. There will be layers and hierarchies of metaphors and symbolism, organizations of analogies and relations, similar to the complexity level of fictional narrative literature. It is a combination of abstraction and environmental observation.

Or maybe it is already happening, and it's just a little check mark next to a bunch of check marks that indicate something symbolic and abstract about the future.

Huge PR move, but i dont think it's gonna work. Do people really need to "send a human" to mars? To prove what to whom (the soviets are no more). It's not like we haven't already been there and taken our pictures. Or that we expect any surprises from this mission. How about we make a plan to terraform Mars? Or to work on more mysterious things like genomes, like the brain etc? Sending a human to mars is a PR move, maybe typical of our times, but not useful.
What you're saying is not really correct.

You cannot just "buy a second 2xlarge" and then recombine them into a 4xlarge. The 2xlarge reservations and pay attention here need to match on their purchase date and hour. I.e they have to be bought within the same clock hour on the same day.

If you reserved a 2xlarge at 2014-12-01T22:59:59Z, you couldn't even combine it with one bought at 2014-12-01T23:00:01Z. Yes Amazon is that picky about it. While you might be able to muscle that through a sales contact, it's not even available to customers on business level support, so anything more than a day apart and you're likely out of luck in any case.

So far I haven't seen anyone mention the H-1B applicants already in the country. FWIW that's a large number of people. I don't have any stats on that, but assume that it's at least 50% of applicants.

Many foreign nationals who choose to be educated in the US (often at a major premium as most scholarships or subsidized loans are unavailable) aspire to stay in the US to work post-graduation. There are temporary programs that allow this: F-1 Optional Practical Training (OPT) for 12 months. This can be renewed by another 17 months for a STEM degree holder. The 17 month extension was introduced in 2008 to allow the candidate to have two chances at the H-1B lottery [1].

I'm a German citizen who went to college in the US on a F-1 student visa. I worked on an OPT post-graduation before my employer sponsored me for a H-1B. I can guarantee you that I was one of their most expensive employees of comparable education and experience: Preparing a H-1B application (and the associated filing fees) is costly, especially if the government sends a request for further evidence. Just 3 months after I had started (before the H-1B application was filed) I managed to get a 50% raise because I had made myself indispensable and started looking for other opportunities as I felt significantly underpaid. They generally did not give raises to anyone, and as far as I know all of my citizen coworkers continued to be vastly underpaid for years.

If it weren't for the H-1B program, I wouldn't have had an opportunity to stay and work in the country after having already spent some 6 years here.

As an aside: Nobody ever suspects me of being foreign. I'm a white guy with flawless English. However, many of my friends who were born here (to foreign parents or grandparents) are treated with racism. That's simply not ok.

Thanks for your reply. I'll address some concerns, but I think we're closer to agreement than earlier actually.

> Sure, but why not send multiple robots and a bunch of sensors?

Well, yes, we absolutely should. We've got a long history of doing this, so we know what their strengths and weaknesses are. We should keep doing this, I think the vast majority of 'things' that we send to Mars for the next 10-20 years should be robots, not people.

> Humans need food and water to live (don't know how much of the payload will be a year's worth of food/water), and are generally inefficient at converting food sources to energy.

This is exactly the reason we need to send them. Since the eventual goal is (or should be, anyway) permanent colonization, it makes sense to send people right away so that they learn how to make food and where to find water. Robots won't be so concerned with this - and frankly, human ingenuity to find ways of making food is probably better done by humans than it is by robots.

> Wrong. This is why we need autonomous cars. Driving is best done by computers, and humans will agree that it is NOT worth 10k+ annual deaths a year just to give humans "the pleasure of driving".

I would agree with you if this had always been the case. But road deaths have persisted for decades without even the promise or idea that we're working towards a real solution. It's just been accepted by people. I agree that this attitude will change we when demonstrate that it doesn't have to be this way anymore.

But for the last ~100 years, humanity has definitely been quite relaxed at risking death just so we can drive cars (or, walk around nearby others who are driving cars).

NLTK is a wonderful toolkit. Its selection of corpera is great and its many utility functions for processing text are incredibly useful and easily extendable.

That being said, a lot of the ML, porter, and stemmer implementations are a bit out of date from the current cutting edge in the field. If you are interested in using NLTK for serious projects, I highly recommend writing custom implementations of these modules or using other libraries.
Neither party really cares. There has been one pro-space guy running for office in the past 15 years.

First figure out, what kind of real world problems this architecture can handle and how to do it best. The architecture will perform very well, if the number of operations, which can do done on a set of data fitting into the scratchpad memory is large, so that communication overhead is small or if the problem can be mapped to the grid in a way that they only require communication with the neighbours. However I would assume that typical real world big data problems don't fulfill these requirements and problems fulfilling them also run well on classical architectures. As soon as you start to need a lot of data transfer, only the cores close to the border of the grid will be able to work, as they get data, the ones at the border are busy with forwarding data to the memory and the innermost just wait ...
Therefore before investing a lot of effort, money and time into a hardware, which many others also do in very similar ways and ask the community to find out, how to use it, spend the energy in innovative ideas to actually efficiently use such architectures. I.e. languages, profiling and debug tools, ...
That's where the real innovation is needed and where there is a lot of room for improvement.
And if you want to stay with hardware it is probably much easier to convince investors, if you can show in a simulation of FPGA prototype that 2 or 3 real world applications showing a very bad performance on classical machines can achieve a substantive boost on your architecture ...
Exactly. There's not even anything you could reasonably call a timeline here, either. There's almost literally nothing to it.
