It is possible with space elevators and a series of Biosphere 2 style experiments. A series of five and ten year experiments can prove the feasibility of building hermetically sealed nuclear powered habitats. With space elevators they can be replicated outside the gravity well in space, spinning at 1G and properly shielded from radiation.

Nano tech developments make space elevators seem less and less crazy. It is not crazy to expect to happen in the next 40 years.

The thing to do is hermetically seal off some deep down mines with nuclear reactors and 30 people for 10 years and prove it can be done.
Right - but when you stop moving the mouse, there's now an extra 17ms before you see the result. I assume that's his/her point.

Maybe this wouldn't bother me any more personally, but I bet I would have noticed it when I was 23!
Well if that's the case, then that's pretty terrible :/
Is gender really that complex? Article suggests somewhere over 1 in 1,000 don't have a simple personal view of their gender, and also most transgender people are trans - changing from one to the other - rather than inter-gender. If people don't want to be male or female, or biologically aren't, or just don't want to identify as either, fine. But to say gender is complex as a result seems like a reach.
We should go to Mars for the same reason we should climb Everest- because it is there. Neil Tyson has spoken very eloquently about this. Having something to strive for inspires people. It inspires children to become scientists, engineers, people who do something that nobody has ever done before, go somewhere that nobody has gone before. And that has untold, unimaginable benefits for all of humankind: https://www.youtube.com/watch?v=pUbOjZWjTLU
And it looks like now they've about-faced:

It's not a matter of skill. For some people, being around others that they don't know very well is tiresome, for other people, it's a pleasure. How well the person handles the situation is a completely different matter.

Also, I don't see any reason to think the above correlates with liking or disliking to be alone.

Well, Francis Bacon died of pneumonia, contracted while stuffing snow into a chicken as an experiment in refrigeration.

It doesn't exactly count as he was experimenting on the chicken rather than himself, but it does sound as though drugs may have been involved.
Interesting. I've been playing a bit with the Oculus Rift DK2, and if I understand things correctly[1], if/when they up the resolution one more "level" beyond the DK2, it should actually be possible to use for many kinds of work. UI design people will need to realize that mile-high letters on the horizon are better than thin lettering close to the head, first (I'm looking at you, Elite:Dangerous docking bulletin board etc).

[1] http://oculusrift-blog.com/oculus-rift-faq/492/

No anchors in the page, I'm referring to: "Will the Oculus Rift cause eye strain after extended use?

The Oculus Rift causes very little eye strain, particularly compared to other standard displays or headmounts.

Normally, when you take a break from using a monitor or TV, the idea is to give your eyes a chance to focus and converge on a distant plane. This is a natural position of rest for your eyes.

With the Oculus Rift, your eyes are actually focused and converged in the distance at all times. It’s a pretty neat optical feature."

The problem with Uber is that the right thing to do never seems to occur to them naturally.

It's an issue that will continue to hound them until they take active steps to change their thinking.
Ask HN: What is the most important NP-complete problem?
If it were possible to efficiently solve a large NP-complete problem, the solution to which real-world problem would have the largest positive impact?

I'm interested in actual, concrete problems where a solution would have a real, obvious, and positive impact. I'm not interested in (except in-so-far-as the real-world problem can be re-formulated as) the theoretical "toy" problems (travelling salesman, subgraph isomorphism, subset sum, etc.).
This is simple supply->demand. Hotels do the same thing when there is a big event in town.
Sounds like an idea that functions well in a niche and seems like complete nonsense in others.

The great thing about the historical diversity in Linux is that, contrary to the complaints of "pointless" differences by folks in this thread, the various distros represent honest differences of opinion about what's good in a system. If you want to do silly things with loopback mounts and containers, there's room for that in the universe, but it would be wrong to impose it on those who don't want or need it.
Phenmetrazine is itself a "designer drug"; as sort of explained in the article, it differs from amphetamine by an oxygen and a couple of carbons forming a morpholine ring including the amine moiety, and its designers hoped it would have some of amphetamine's effects (like weight loss) with less side effects. As with most designer phenethylamines, this turned out badly, though not as badly as e.g. Fen/Phen. (There have been a lot of "designer" phenethylamines; are you really sure that "derivatives [of phenmetrazine] have just started to appear on the grey market"? Are you sure PiHKAL doesn't have a few?)
As someone once described to me, if you have a lot of money, the world's great cities, London, NYC, LA, Hong Kong are your playgrounds. Living, working, and playing within a walking distance or transit-friendly distance is strongly becoming an aspiration for those who have the skills or money to afford it.

If you make $300-400K/year in New York City, you can afford to live a little. Midtown or Chelsea apartment. Nice restaurants. Drinks in bars. $7 lattes.
"Which kind of capitalism? Crony capitalism? What about Workers capitalism? A much different thing than the generic stereotypical capitalism you seem to be talking about."

I'm sorry but this reasoning is fallacious nonsense. No true Scotsman is an informal fallacy, an ad hoc attempt to retain an unreasoned assertion.

A Stuyvesant Senior Made $72M on His Lunch Break
To me, a fast bootup is a non-issue. I want "less magic" with my computers. I want to have control over my system. Surely it must be possible with systemd. But the good old sysv-init works for me and I am familiar with it. Shoehorning any system for every possible need is probably a bad idea. True with systemd and true with sysv-init or any system.
I'm all in favor of price surging and all that, but it saddens me that Uber spends so little time thinking about PR. Particularly, there's an obvious fix that will probably win them a lot of support: during surges, only charge the 20% fee on the base price. That way they can very justifiably claim to be earning no profit from surge incidents and are increasing fares solely to create enough availability.
At first glance this book appears in many ways to be a spiritual successor to SICP... does this hold up for anyone who has read it more throughly?

There's also the unspoken "X has risks, and I don't want to do X, therefore X should be illegal".

I ride motorcycles. I have friends and family involved in scuba diving, paragliding, football, rock climbing, hell - even horse riding.

_All_ of those activities have "well known risks of serious injury or death" associated with them, and each of them I've heard recent stories of death in the extended circles of my family and friends.

I'm not sure whether the "designer drug" risk is anything like as high as some of those legal and "acceptable for your children" risks.

My approach is less "asking are the risks of X greater than the risks of making X illegal?", but closer to "Quantify the risks of X, work out which can be mitigated or reduced without needing to ban X, make sure participants are informed of the risks, and if needed ensure training/insurance/licencing is available if required".

Thirty thousand people a year are killed in motor vehicle accidents in the USA. We don't react by saying "Make cars illegal" - we manage, mitigate, reduce the risks (quite successfully, that 30k is down from 40k 10 years ago, and over 50k back in '79 and '80) - then we declare 30 thousand dead people a year an "acceptable cost" for the benefits of private car ownership.

Why aren't we able to be that rational about "designer drugs"?
If you strike it rich, would you like to hedge a bit by betting a percentage of the $5M donation on a promising horse in the race called Julia?
I think Amazon when comes to money especially on the web service side of things doesn't think in this way.

I'm more oriented that the language is new so is still hard to find devs without consider that is a very a big work port this huge amount of api.
You see, i am arguing from practice and you from theory. In theory you are absolutely correct. In practice the vast majority of code is NOT written in total languages. A more likely scenario is one where somebody is using language X and, in the middle of a project they decide there's this recursion thing they read about or learned in school. And off they go. In that context. In the context of a practical world where virtually nobody is is using total languages, the injection of recursion by the wrong people is dangerous. I say this from first hand experience.

Let's just agree to disagree.

The Raspberry Pi GPU has been fully and openly documented now, so it should in theory be possible to boot it without a binary blob. You just have to reimplement enough of the graphics stack to make the CPU happy (?)
Yes, software like this exists. Using multiple overtones to reconstruct a single note is pretty basic in this field, if you search for "wave to midi" software (for example) you'll find a few that do this. The most advanced right now might be Melodyne [1] (used in the article), which also allows you to pitch-shift the detected notes (and all their partials), without affecting the rest of the sound. However it's quite proprietary, and I don't think the details of their algorithms are available, but it does a good job on a variety of instruments. The polyphonic detection can never be perfect, of course, especially with layered organic instruments such as voice and winds, it becomes impossible to determine what note a particular partial belongs to.

the Concorde used about triple the fuel per passenger of other aircraft of its era (like the 747). Even with relatively cheap oil, that added fairly substantial cost.

Additional factors that led to its demise:

- it was a very loud aircraft, and couldn't go supersonic over populated areas due to sonic booms. This led to significant limitations on viable routes.

- it didn't have the fuel capacity to make trans-pacific flights. This also led to limitations on viable routes.

- Concorde required specialized pilot training, specialized maintenance, and even a flight engineer (which more modern jets don't require).

- supersonic flight wears out airframes. I worked in a museum with Concorde G-BOAG, and could see several spots where the airframe had been patched in more substantial ways than our other similarly-aged or older airliners (Eisenhower's 707-based Air Force One and the prototype 727, 737, and 747's.) Airbus didn't want to keep maintaining the airframes given the condition they were already in.
Emacs makes complex things possible and simple things hard: http://www.tjradcliffe.com/?p=74

That post is the fifth most popular thing on my blog, all from search-hits looking for how to count words in Emacs.
And you can have something fun like the following in your bashrc to allow attaching to your running emacs daemon any time you need in the terminal:

function semacs() {
emacsclient -t -a "" "/sudo::$(realpath $@)"

I think you hit it on the head to point out that the phrase is meaningless. The whole systemd phenomenon is very Freudian, right down to its name, it's as if systemd fans seek a single component to point at and call "the system", to worship as pater familias. "The system" will not only free you from being precise about what components serve what purpose, it will end all arguments and bring order to their lives in a way that decentralized purpose built components will not.

Maybe they should just use OS X and be done with it.

In the cosmic sense, Mars isn't terribly far, at least, or far off on most of these, given potential technological progress over the next few hundred years. I'm pretty confident humans will briefly visit Mars before 2040, and will probably maintain a continual presence, even as meat.
The Growing Network of Fintech Accelerators Globally
In the case of the shelters, the problem is not how to allocate the funding; the problem is what dorm to put them in.

I agree that it is clear that the socially-desirable action is to give shelter independent of gender; it's also clear that some existing systems for support do not allow that without effort, and so far the effort has been allocated elsewhere.

Ugh, just think about being trans and using a public restroom. Now think about being of high-school age, and being trans, and needing to use a bathroom. And yet if (more than) 0.1% of Canada is trans (dunno if that's true), then all of my high schools had (at least) one trans person, presumably closeted. Poor bastard. But on the other hand, what action can the administration take that isn't worse than nothing?
How to Do Unlock Any Android Smartphone Pattern Password
It is better for Uber to be as honest as possible about their practices. This gives everyone else the greatest insight into the corporation and allows us to form more accurate opinions about their practices and to decide whether or not to support them.

A company hiding their intentions through obfuscated PR techniques is detestable. It also does not appear to be a great long-term strategy. Look at Comcast, they love to play the PR games and they are almost universally reviled because of it.

People will support honest organizations that are improving things. Trying to wrap fundamentally flawed systems in the pretense of nobility is a silly game to play and many are tiring of it.
Is it really 'simple' supply & demand? From Uber's Tweets it sounds like they actively alter the prices. Does Uber actually offer a truly fluid, lasseiz-faire market?
Dispappointing to see this post on hacker news. Most of the people getting angry at uber don't even understand how their system works.

Some random guy shared a screenshot of a 4x surge on uber black and now the media is saying "uber making $100 off fares in a hostage situation!". So silly.
You and others speak as if nobody ever had a reason to make their distro work differently. That they're just all evildoers who change stuff for no reason. Maybe you can say there is some of that, or that it emerges as a net result, but in a lot of cases people have honest differences of opinion about the right thing to do. So if person 1 has idea A and person 2 has idea B, you're going to deny one of them to get their problem solved simply because they are scratching at the same itch from two angles? Sounds kind of like software fascism to me.
That doesn't prove anything. Their twitter person was probably just reporting on the current surge level.
Not quite sure if this is what you want, but the noisy channel model (call it "Bayesian" if you must) spell checker I linked to above is inspired by the classic approach to speech recognition (and codebreaking, and machine translation, and natural language parsing).

Norvig's algorithm essentially computes a censored form of Levenshtein distance. Dynamic programming algorithms for computing Levenshtein distance play a major role in gene sequencing, and also pop up in time series form as dynamic time warping.
To be fair, it took them ages to start getting serious about Python. It's still not what I'd call a first-class citizen, in that boto (even with paid AWS employees on it) lacks support for things like their ElastiCache discovery protocol (last I checked earlier in the year).

Source: I heavily contributed to boto in years past. It has progressed by leaps and bounds since then, but I still don't see it mentioned in the AWS blog posts when Ruby/Java/PHP get new shinies.

Because it's not really as location independent as you think.
Fiction is an outdated medium
There's still a large value IMO of working physically next to those you work with. The ideas flow easier, meetings can happen organically, there are no timezone issues, etc.

Yes, this sector can work remotely less painfully than others, but that doesn't mean its optimal.
My understanding is that Mars has a dead core and no magnetic field, meaning severe problems with radiation, and even if we melted icecaps and thickened the atmosphere, Mars' lower gravity and lack of a magnetic barrier to solar wind would lead to gas particles escaping to space, and the atmosphere eventually thinning again.
Looks cool, where did you buy it from?
Except most teachers only cleared the RAM because they didn't know any better, so you could "archive" whatever you wanted in the flash...
Any form of adventure first need perform the "stick a pole somewhere" process (if returning home is expected). At the time, just getting there is an extraordinary act, requiring a supreme effort leveraging advanced technology and taking great risks. Several of the allegedly first discoveries of America (Lief Erikson, Christopher Columbus, others) were content to arrive, take a brief look 'round, and return home. Topping Mt. Everest involved little more than planting a flag and heading back down. Apollo, indeed, planted a pole - and even took time to drive around a little before heading back with a few rocks.

Early on, just getting there and coming back intact is hard enough. Get that process down first, then see what else can be done.

Methinks the real hindrance to further manned space exploration was: after great effort, we stood someone on a dead rock. Yeah, sorta interesting, but not really compelling; no really dramatic scenery, no minerals worth the cost of mining, too exhausting to think (after that huge effort) of the place of a jumping-off point for an orders-of-magnitude harder effort to go somewhere else not much more interesting when you actually get there. Fascinating, yes, but few people want to contribute vast sums, if not their very lives, to a long boring trip in a can (even with a Morale Officer) to a giant rock quarry. We're not talking the planet Pandora or some such here.

And per another poster's detailed list: it's very, very expensive to send a meatbag somewhere.
I think we should be doing both - and that anyone that claims to know the ROI for that kind of exploration doesn't know what is being measured.
Bluntly put, Haskell's graphics support sucks. There are different libraries with different levels of support, but none are complete or high level. There are also Haskell like alternatives like Elm and PureScript, but they're experimental. And finally there are some Haskell to JavaScript compilers, but I'm not sure what DOM manipulation is like with them (and they're all experimental).

I'm building a Haskell desktop app over winter break (DMX and light show controls), but after a fair bit of research, I came to the conclusion that its best to do the GUI in JavaScript and speak with a Haskell server over a WebSocket.
Sounds like trying write software to identify and enhance the most "important" elements of paintings, or to clarify the theme of each stanza of a poem.
This looks pretty cool. How well documented is its GPU?

The Raspberry Pi folks managed to pry documentation out of Broadcom http://www.broadcom.com/docs/support/videocore/VideoCoreIV-A..., with an FFT example included in the standard distro https://github.com/raspberrypi/userland/blob/master/host_app..., resulting in porting the Deep Belief image-recognition SDK to that GPU http://www.raspberrypi.org/more-qpu-magic-from-pete-warden/ and SHA-256 http://rpiplayground.wordpress.com/2014/05/03/hacking-the-gp...

I'd love to be able to do that kind of thing on the ODROID-C1, especially since its GPU sounds like it's a lot faster! I see that they're designed by ARM rather than Broadcom, and there's a reverse-engineering effort that has produced something of a GL implementation on them http://limadriver.org/ that has Quake 3 Arena running on it already, and faster than the binary driver, but not yet playable https://libv.livejournal.com/23886.html; but that effort seems to have stalled last year. But it sounds like it was, at the time, limited to working from reverse engineering rather than official documentation https://archive.fosdem.org/2013/schedule/event/operating_sys..., and while ARM has a lot of development documentation on their Mali site http://malideveloper.arm.com/develop-for-mali/sample-code/, none of it seems to be for the GPU itself, but rather for the OpenGL ES implementation they've written for it.

So what's the deal? Is the GPU really actually totally undocumented officially, with the only available information being a dead open-source project that produced a half-complete free-software OpenGL implementation for it by reverse engineering? Or is there more stuff out there I'm missing?

(In any case, it's pretty incredible that in 2014 you can already buy an 8-processor single-board computer that you can program for US$35.)
You should definitely check out Brent Yorgey's diagrams package (see examples here http://projects.haskell.org/diagrams/gallery.html) which is a declarative drawing library. Graphics are described in an essentially "mathematical" way, and as you can see, many of the examples come from mathematics.

It answers the question in the comment I was replying to: that there are conscious humans watching the price changes.
Working remote is great, most of the time. The biggest benefit is not having to commute . . . saving on gas, mileage and most importantly TIME. I would recommend at least trying it out.

The only lacking part is office banter . . . socializing . . . but that is good and bad to miss out on. With skype and conference calls it's easy to stay connected with team members.
