Not long ago I thought the same thing. We can live on the ISS, so even if there's no oxygen and temperatures will be perpetually 200ºC above current, I'm sure we can construct habitats (even small cities) that could be self-sustaining and live. But here's the catch: these things don't happen instantly. It's not a turn-based RPG where somebody decides one turn to "build self-sustaining, hermetically sealed arks", before these things become an absolute necessity we may have already lost the infrastructural or technological abilities to do so (even the raw materials come from /everywhere/ on Earth these days). Worse yet, when the social-economic inequality is the difference between life and death, I'm sure a lot of people will be very angry. And very angry people do stupid things. So you build an ark to live, but not everyone outside is truly dead yet, I'm very sure these people would like to get in. Destructively.

All of this fake news discussion makes me think about McLuhan. It's as if we are forgetting the point of internet.

> McLuhan's central thesis, encapsulated in the famous phrase "the medium is the message", was that the technologies through which we take in information - the media, broadly defined - become "extensions" of our bodies, exerting a profound influence over us. When an important new medium arrives, it can reshape who we are as individuals and as a society. [1]

> Electric media, being cool technologies that promote interaction, would bring back our lost tribal consciousness, McLuhan believed. But our tribes would no longer be small, isolated groups. Because the new media spanned the planet, we would become members of a "global village". [1]

They succeeded better in convincing me that there are no habitable choices in the solar system than Titan being the obvious choice. Mars will probably be our next destination as the best-fit of several ill-fitting choices. We need a propulsion revolution to reach Titan.

But do people even know the types of hardships Asian Americans had to endure?

How many people know about the Chinese Massacre of 1871 in LA?

If we really are going to compare suffering, wouldn't Native Americans be on the top of the list? And yet their suffering isn't really something that is focused on.
The Langeled underwater pipeline, carrying natural gas from Norway to the UK, is a bit longer than the Barbados-Surinam distance (at 1200 km), and cost approx. 2 billion USD adjusted for inflation. That's a really big-ass pipeline though, at 44" diameter. I guesstimate they could probably get this water pipeline done at about a hundred million USD.

Edit: Digging a bit further, subsea pipeline lay cost can be roughly approximated at 0.04 million USD per inch-kilometer (that is, multiplied by pipeline length and by diameter in inches) for 8"-24" pipe. Furthermore we can estimate that Barbados would need a flowrate of 5 000 L/s to supplement their water supply, giving an optimal pipeline diameter of 8". That means it would cost 942km * 8in * 0.04 million USD/(km*in) = 300 million USD.
Right, true. I guess I'm used to working on languages where you can stick everything into a uint64, but that isn't the case with something like returned structs. if you controlled the calling convention you could do it in C.
Aren't there a lot of accepted jokes about black men being well endowed or otherwise physically gifted?
What do you base that estimate on, given that planning, permits, work etc don't scale with the diameter of the pipe?

A valid question and one that is getting much less attention than it deserves (probably because some of the answers are rather uncomfortable).

Locally, welfare can be egoistically motivated. Just about everybody would be willing to pay serious taxes to raise that one beggar off his doorstep - if only to keep him out of sight. We like to think of that as altruism, but it hardly is. Now ask those same people to pay serious taxes for the benefit of poor people thousands of miles away and you get a completely different picture.

Enter mobility: If you raise "your" beggar, someone else might just hope that theirs will go to a place where they will be raised (your doorstep). Clearly, egoism won't work as a motivator anymore because you don't want to be the new charity central. Therefore, welfare has to happen on the same organizational level as freedom of movement and that's where the relative unwillingness to help those thousands of miles away comes in again. Even basic income suggestions quickly lose their pie in the sky utopia feel when it comes to the question of access/citizenship/migration.

The US was literally built on mobility as a substitute of welfare, but once the original anti-welfare "stay poor or go west" was exhausted, the inherent antagonism between mobility and welfare continued to stay obscured behind other ideological concepts, "temporarily embarrassed millionaires" and all that. The EU is learning the hard way, but it is impossible to separate valid concerns and solution-finding from all the noise of and about stupid racism.

Thanks very much for your suggestions.

I have a utilitarian understanding of mathematics (vector spaces, SVD, orthogonality, invariances, etc.) and over time appreciating the underlying characteristics/relationships, which I recently got a taste of from T. Wickens, The Geometry of Multivariate Statistics.

I look forward to understanding measure theory and related math.
Great resource!
> On Earth, we are shielded from GCRs by water in the atmosphere. But it takes two meters of water to block half of the GCRs present in unprotected space. Practically, a Moon or Mars settlement would have to be built underground to be safe from this

> Underground shelter is hard to build and not flexible or easy to expand. Settlers would need enormous excavations for room to supply all their needs for food, manufacturing and daily life. We ask why they would go to that trouble. We can live underground on Earth. What’s the advantage to doing so on Mars?

It's never seriously discussed, are they expect to live full time underground on Mars? Why then? We can live same way on Earth.. Does Elon Musk knows something we don't?

Terraform the moon. I want to look up to the skies and see a green moon every night. It is unfortunate we haven't spent a dime settling a moon base and studying the possibilities of creating a livable atmosphere on the moon being just a couple days away.
Native Americans are probably the most unfortunate group. To put it in business terms, I think certain ethnic groups have just been more successful in their marketing than others ;)

Though I don't read it regularly, I often find myself following links to what turn out to be good articles at Smashing Magazine. It's not exactly what I'd call a tech magazine - the focus is web development and design.

For something more broadly IT related, there is The Register. You'll have to forgive their intentionally over the top, tongue-in-cheek, british tabloid writing style (I've noticed a bit of this has rubbed off on Ars lately). If you can look past that you'll find that they do a really good job of staying up to date with industry news.
> Why then?

Because it's a different planet.
I strongly believe we'll never permanently settle anything beyond earth, for reasons pointed out by this article among others.

That said, please prove me wrong, I would be so very happy to be wrong.
I don't understand why we're doing this. They will eventually be contaminated in the next 500 years and that's not long evolutionarily speaking. As tech becomes cheaper and the third world starts breaking into the "modern era", we'll have more failed satellites embedded in the sides of every moon in the solar system. And NASA legitimately struggles to make these devoid of life. An exuberant little nation punching a little above its weight category certainly won't.
Perhaps he meant Nexus 5X, which is USB-C.
This article is about one of the mechanisms, which wasn't well known.

We know there's a bunch of reasons why poor people are unhealthy - more smoking, more alcohol, worse food, less exercise, more dangerous jobs, less protection in those dangerous jobs, less exercise, less access to health treatment (even if it's free).

But this study:

> The findings, in Science, had nothing to do with the unhealthy behaviours that are more common in poorer groups.
> It might be possible to live suspended by balloons high in Venus’s atmosphere, but we can’t see how such a habitation would ever be self-sustaining.

I think they're a bit too dismissive here. I'm a great fan of the colonisation of Venus, and don't really see a problem with self-sustaining stations in a place with pressures and temperatures naturally fit for humans, with lots of sunlight for energy and lots of CO2.

After all, as long as there is plenty of energy, carbon, and oxygen, we should be able to synthesise mostly whatever we want.
I think a lot of it comes from the modern definition of racism involving power + prejudice. As a group Chinese people appear to be relatively successful in society (certainly in tech) and so sit slightly higher up the power scale than black people do. So if a white person makes a negative comment it's going to appear as societally "punching down" much further if it targets a black person vs a Chinese person.

Basically it seems worse if you reinforce stereotypes against a group that is already struggling.
There's still cost to it. It basically boils down to: do you lose more money during a manual maintenance period, or by hiring extra people to do all changes in zero-downtime style. (Or doing slower development with the existing team) The technology for transparent changes has been available for decades, although it's true - it's much easier to use today. But it still needs extra work. And someone has to pay for that work in the end.
Ask HN: Should I take an online college after completing CS? (chem or biology)
Here is my story:

I went to a college and immediately got a job (when I was in first year). After 5 years I got my CS degree and now I'm a Head of Software Development at a good company with a good pay (at least for Croatian standards).

College was pretty easy for me (most of the things I have learned at work), wrote 4-5 research papers, professors appreciated me, etc.

I feel like I need more education/knowledge. I'm interested in all kinds of topics, mostly biology and/or chemistry. I would like to make software for biology and chemistry but I don't know where to start.

Is it worth it to take/pay some online college courses? I work 8 hours a day (mostly) and I'm pretty positive I could do college work after that.

What do you think? Do you have any opinions on online college courses and could you provide me some names? I did some research but I know how marketing works and I don't trust them. :)

I'm in Croatia and I'm 24 but I will most likely move to Germany or Switzerland by the end of the next year.

This article has no good reasons for Titan, it doesn't discuss water, it doesn't discuss energy or how to grow food. It says that because you can fly there and there are dunes and a liquid surface in some places its like Earth, but that doesn't help us to survive at all.

To survive we need water, food and energy. How are we going to get that from Titan as opposed to Mars?

They almost had me until ...

On the surface, vast quantities of hydrocarbons in solid and liquid form lie ready to be used for energy. Although the atmosphere lacks oxygen, water ice just below the surface could be used to provide oxygen for breathing and to combust hydrocarbons as fuel.

Riiiight. And you're going to get the power to electrolytically split that water into hydrogen and oxygen where, exactly?

(Whoever wrote that piece forgot that water is one of the end products of combusting hydrocarbons with oxygen, not a starting point. Basic physical chemistry and thermodynamics.)

Let's go through the energy budget of a Titan colony point by point:

* Titan is so far out from the sun that the available solar power is roughly half what it is in Jupiter orbit, which in turn is a tenth of what we're used to (per my skimming of this source: http://www.lpi.usra.edu/opag/nov_2007_meeting/presentations/... ), and that's before we factor in the murkily opaque atmosphere; I infer that photovoltaics are a non-starter on Titan.

* Some analog of wind or tidal power might be workable, but remember we're talking about an ambient surface temperature down around 90 degrees Kelvin; the free energy in the atmosphere will be drastically lower than the equivalent on Earth (temperature on the order of 300 Kelvin).

* Forget hydrocarbon combustion (coal -- snort!) because there's a slight lack of anything to combust it with.

* This leaves nuclear as the sole reasonable option for powering a Titan colony, which opens up a raft of other questions: if Fission, then what is the abundance of 235U or 232Th on Titan, and how accessible are the necessary isotopes? And if Fusion, well, first we need to demonstrate a working base-load producing fusion reactor here on Earth.

* Let's also bear in mind that a thick atmospheric blanket of mostly nitrogen at 90 Kelvins is, shall we say, a little bit chilly, and the ground any human-occupied base is built on will be a mere hundred Kelvins lower than the lowest temperature ever recorded in Antarctica, and we're going to need a lot of energy just to keep from freezing. (Also note that any significant human presence there is going to end up pumping out so much heat pollution that there may be eventual weather disturbances as a result.)

It's a bit like imagining how hypothetical Venusians might build a colony on Earth, with their requirement for pressurized habitat domes kept at a thousand degrees Fahrenheit (in American units).

Disclaimer: I am not a planetary scientist, I'm just a science fiction writer who thinks about how this sort of thing looks from 30,000 feet rather than trying to quantify it with enough precision to justify a research grant. But I still think balloons in the atmosphere of Venus or tunnels drilled into the walls of Valles Marineris make more sense.
I don't think the mockery received by the OP was okay, so no, that wouldn't be okay either.

Having said that, firstly, understanding why a bad behaviour happens is important in stopping it: maybe students should meet their roommates earlier, or get introduced to them over the phone, or get pamphlets titled "How Not To Alienate The Person You Will Live With For The Next Year", or something.

Secondly, the OP is talking about people who were raised in a totally different culture. "Black" in the context you're talking about presumably means black Americans, who live in the same country as you, speak the same language as you, and get the same TV as you. As someone from outside America, I'm quite happy that the cultural differences between us exist, because they make life interesting - however, they can be an obstacle to communication.
That's a surprisingly widespread law, worldwide. One that's rarely enforced.

In other words, I don't think anyone asked for a permission here - it would not be allowed either, but IMHO the authorities don't care as long as there's no major problem.
Does the colony really need to be on the planet? Why not start on the orbit? We already do it to some extent, can't we try to grow it? Is the spinning disk ok for artificial gravity or the diameter would have to be extremely large?

Another alternative could be floating, suspended or at the bottom of the ocean colony.

It's like doing test driven development.
I am probably completely wrong but it seem easier and perhaps more fruitful to build the proper shielding in a station/ship and build a network up in one of the asteroid belts.
Not rude at all! I was a little aggressive with the app UI quirks I found.

If anything, your app is a great example that most users don't care or notice non native UIs as much as developers do. It shows the viability of using such a framework. So don't let me get you down, I just enjoy breaking software :)
Water and energy are discussed briefly:

On the surface, vast quantities of hydrocarbons in solid and liquid form lie ready to be used for energy. Although the atmosphere lacks oxygen, water ice just below the surface could be used to provide oxygen for breathing and to combust hydrocarbons as fuel.

Travel difficulties aside, endless piles of hydrocarbons lying around ready to be used by people who don't need to wear pressure suits sounds like a good reason to go to Titan instead of Mars... But I get the feeling that the authors are way too optimistic about humans surviving on Titan with "warm clothing and respirators".
If this seems interesting to you, I would suggest reading: "Gödel, Escher, Bach: An Eternal Golden Braid" [1]

Well, I would think that "interoperating with external programs" is a part of UI, not of the renderer - but that's a bit of a grey area.
I've tried it:

http://cowlark.com/flooded-moon/

The maths are interesting. I tried figuring out how thick the atmosphere would need to be, but I kept coming up with ludicrous answers --- one model I tried, in order to get breathable pressure on the surface, the atmosphere had to extend out at least two lunar radii. That would have made the moon just a simple white fuzzy ball in the sky, and you'd never see the sun from the surface.

I need to get back to this and see if I can improve the models a bit.
We expect human nature to stay the same. Human beings of the future will have the same drives and needs we have now. Practically speaking, their home must have abundant energy, livable temperatures and protection from the rigors of space, including cosmic radiation, which new research suggests is unavoidably dangerous for biological beings like us

I would expect the complete opposite if we really want to colonize the solar system at some point. It seems far easier to modify/replace the human body than to try to suit all it's biological needs.
Sorry, my bad. Didn't realize that larger airports have separate Schengen and non-Schengen terminals.
Absolutely. One of my favorite performers (Daedelus) uses a monome for his live setup, and there's nothing on Earth like a Daedelus set. It would be exceedingly difficult (or essentially impossible) to specifically match or emulate what he does with a 'traditional' DJ's setup.

That's not to say that what he or other live performers do is inherently better than someone proficient with turntables, of course. He chooses a monome as his primary tool to achieve the type of performance he strives for, and for some, a controller like that is simply not the right tool. To me, it's all good — the hardware involved has little to no effect on how well a performer can match or exceed my expectations.
Trap it in a giant plastic bag ;)

Yaysayers will always find an excuse why something they don't like to be impossible isn't. "But the Wright Brothers!" and all that...
Did we read the same article? It literally rains methane on Titan. Combustion would be tricky due to lack of an oxidizer, but presumably we could use something like the fuel cell technology that's already deployed here on earth to generate electricity from CH4. Energy, at least, would not be a problem.
radiation exposure becomes an issue on the longer term in space.
Speech is already controlled by corporate interests, you're just not noticing it because the claims are its done "to fit your preferences". Whether that's true or not, or really is it to fit your preferences or to keep you longer using their services (do angry users use FB more often?) you can't tell. The algorithm to control speech is already in place, but the results are completely self serving for FB. What we're arguing for is to consider whether the current solution is a net benefit to society.

False information and hate speech should be downgraded, even banned, when it's done to be shared with millions of people and it can lead to actions that are not beneficial to society in general.

Let adults be adults is fine enough, but I don't understand why people should be allowed on disseminate verifiably false information. If it's the state control that bothers you, make a democratic system to flag it. It's sill better than allowing FB and Google to give you what their algorithms say keep you using their service.
Unless you can reduce inequality to zero - Harrison Bergeron style [1] - you can't fix this by reducing inequality. It's an ironclad law of mathematics that 20% of the population will be part of the bottom fifth.
