But it's still much easier to grab even a thin gas than it is to mine anything. An extremely convenient source of both carbon and nitrogen is going to be a huge benefit in terms of trying for long term sustainability. The Moon does have plenty of oxygen in various minerals and hydrogen in the polar ice but you need more than that.
Yeah, the guy who said he was at Burning Man and wondered how we would deal with human shit on Mars made me cringe.
Thanks! When I finished the rebuild, I will be able to create and maintain some new features based on what users want. Will keep de the paid plans in mind! Maybe just a very small amount, it does not cost me that much to run the service.
I've never listened/watched the Q/A session from any of his talks, are the questions from the audience usually better?
It's super weird, also that refueling question:

People have to wait weeks in space to just get refueled?

Why not send 4-5 tankers (supposedly reusable) up first and then refuel almost instantly? That thing seems really low scale/budget.

For music at least, you can get the best of both worlds with Google Music. Any songs you purchase, you own. You can download them, back them up, migrate them to a different service, whatever. For songs you don't own, you can still stream them and save them offline as long as you're subscribed.

AFAIK no real equivalent to this exists in the video streaming world yet. Plex is starting to come close though: https://www.engadget.com/2016/09/26/plex-cloud-online-server...

> Human colonization, in this context, is a bait-and-switch

A switch with what, exactly? If he's just trying to make money, just space tourism alone would be more than enough, since he could charge the same as he'd charge for a Mars trip . Also, if your goal is to colonize Mars, a pretty critical step one is getting humans to Mars. It's not some nefarious plan.
The biggest problem with teaching reading is that not everyone is ready or interested in learning how to read at the same age. Studying why we can't force a random group of 7 year olds to learn how to read is missing the point. We homeschool. One of my daughters became a fluent reader very early. The other when she was a few years older. You can't force people or children to learn something they're not interested or aren't ready (for various reasons) to learn which unfortunately is basically what the educational system is built around. It's really less about methods which make a marginal difference.

The problem with higher education is that we are still forcing people into those programs. If you want to make a good salary you take CS. Whether you have any interest or passion in that area is not relevant. Whatever your level of mathematical maturity is not relevant. You are of the right age and you want a successful career that's where you go. It's no wonder that teaching all those people CS is going to be difficult. It's still the same faulty approach to education. Everything can be taught and everyone can be taught and if it doesn't work we just need to find a better way of force feeding them.

Compounding that even further is that teaching is difficult under the best of circumstances. In higher education it's often researchers who are asked to teach (or students) and while they may be brilliant on an intellectual level it doesn't necessarily make them good teachers.

EDIT: And a thought on the bi-modality ... I would expect to be able to see this sort of modality at the output of a CS program. I would expect modality amongst students who graduated with the same grades. I would be really surprised if students graduating with the same grades perform similarly in software development tasks. Not clear to me what a CS grade means and how they relate to any natural abilities to e.g. write computer programs.

Elon actually addressed this, you only need the booster from Earth. For all interesting targets the spacecraft can launch by itself and get back to Earth.

The point of the booster for Earth is both to get out of Earth's gravity well and through its atmosphere (both of which are far less of a problem on Mars).
I would never say "it won't work", but I do think we humans have a tendency to turn to technology to solve our most basic problems, while the real solutions lie within us (where most people never look).

I believe we should first learn to clean up our act on planet Earth before we export anything of our existence and what we do.

To me, the real revolution that needs to happen is a spiritual one - a statement that will only be understood by those practicing meditation. Our brain has so many "undiscovered" capabilities. Discovering them will change our behavior and ultimately allow us to survive on Earth.
I am not sure it is illegal what Palantir is doing (the court case will determine this), but on the face of if 20% of the people you hire are of Asian decent this does not look unreasonable. If their funnel had 20% Asian candidates and they hired 20% I don't think the DOL would have intervened.
Aside from the discussion of JS and React Native, I want to highlight this:

> Perhaps more importantly, your software development platforms also shape you as a software engineer. A software development platform encourages (or forces) the use of one language over another, prioritises certain architectures over others, requires using specific tools and workflows, and marries you to an entire ecosystem and its developer community.

People talk about the "right tool for the job" and "good developers are polyglots." This is true to an extent, but there are still communities with different priorities, and they often form around languages and tools.
Never mind repairing old stuff; just make it easier to pass on stuff. I suspect that Sweden is similar to Norway (where I live) and immense amounts of current electronic gear is thrown away.

> Primarily because the "genetically inferior" person somehow had more motivation and drive than the genetically engineered ones.

One thing he had over most of the "valids" was the opportunity to choose his path. The valids' parents made choices for them (Jerome was made to be a swimmer, the 12-fingered pianist, etc.). It's not wholly different than seeing a child prodigy fail as a functioning adult. They don't all, but many times when someone excels in youth in some activity and is pushed into it by the adults in their lives, a failure later leads to an inability to redirect their energy and lives (for extended periods, they become depressed). They existed for a singular purpose for so long and aren't capable (emotionally, mentally) of dealing with the freedom to choose what to do next.

Vincent's character possessed drive for several reasons: 1) he was better than his brother as a swimmer/athlete, and so knew that his in-valid status was nonsense; 2) he was resentful of being shunned by both his parents and society, and motivated by that; 3) as an in-valid, he had no purpose in life, so once he chose one, he put everything into it. The valids who still possessed their potential were similarly motivated with regard to their goals.

Hahaha, please tell me another one Mr. Trump.

Being old is not an indicator of success.

You seriously seem to live in some wonderland where the quality of a candidate just magically appears out of thin air.

I want candidates to have studied. Studying isn't gaming. Studying is being smart. I want candidates that studied. Those that didn't I don't want. They don't want the job badly enough.

I routinely test older candidates who can't program anywhere outside of the little box they made for themselves, and freak out when they see a programming language that isn't the one they've used for the last 20 years. Is that inhumane?

But we are in such a critical moment right now in terms of our ability to really destroy the ecology we depend on. It's like there a small fire started in the bathroom and some of us have chosen this moment to start planning a new vacation home.

For Elon Musk personally, he's so involved in the shift away from carbon through his work at Tesla that it feels like it balances out. He's a leader in fighting the fire and also spending half of his time on the new house. But in general I can't really commend the aerospace engineers working on problems like this when we are so close to being able to fix so many age old problems on Earth.

This is such a critical couple of decades for Earth technology.

I had my first JavaScript coding interview several months ago. The two days before, as I reviewed all my bookmarks of resources that either helped me a lot or that I continuously return to, I consolidated the links into a single page. At the end of the interview they said sorry to say this but we are looking for a Go developer and would hire me if I took a month to learn Go but I really wanted to build one awesome app using JavaScript before I moved on. The most important thing on the list is the link to What the heck is the event loop anyway? video

I've constantly racked my brain on the Underserved Communities and Social Services: my dad is a Vietnam vet and my mom (while we were growing up) fit that single mother middle-class type...how does technology help them?

Part of the problem is they aren't tech savvy the way the HN community is - so what works for our community doesn't exactly work for theirs, or that they even use technology to the extent that we do (i.e. does technology even solve this problem?).

The other problem is revenue/profitability...this population is inherently cash-strapped, so trying to create a technology solution that likely lies in the Tech-meets-Consumer Discretionary industry, well, who among these people can (and will) afford such services?

It frustrates me to no end...because I want to help, but I can't seem to find a viable solution whenever I build something out.

It's further a problem because it doesn't follow the general YC/Paul Graham rules for creating solutions - solving your own problems. Most techies aren't also veterans or single mothers, so while it was a problem I experienced second hand growing up, it's not something I live with today, other than my innate desire to help others. It's very hard to solve a problem you can't experience first hand.

Does anyone have any ideas on how to solve these kinds of problems? Am I approaching it wrong?
For constant power on Mars you need 2 kg of batteries for every 1 kg of solar panels. On the moon you need 50+ kg.
At least in my case, I see trying to start a Mars colony as a death trap. It's the illusion of carrying on the human race, but it's really just dooming a bunch of pioneers to a grim fate in an extremely hostile environment. I think making a south pole colony would be hard enough, let alone a Mars one.

In the event of a major nuclear war, living in Antarctica won't protect you from environmental radiation, which will be at highly elevated levels for decades throughout the entire planet.
HA! Hahahaha funny, NY basically functions as the precursor to Federal policies that have dubious privacy and civil rights merits
>Does that protect people from the event of a major nuclear war?

In the distant future, Mars may not necessarily afford protection either.

It's going to be sad if the doctrine of mutually-assured destruction some day applies within a multi-planetary context.

Most likely this would take the form of national territories being established on Mars by existing nuclear powers, the weapons either being imported or fabricated on-site.

Of course, the wierder scenario is one where advancements in propulsion technology allow for faster and cheaper delivery of payloads to Mars, resulting in some sort of Earth-to-Mars nuclear strike capability. Transit may remain quite latent, but it could still do the job. Imagine having weeks or months to contemplate an incoming nuclear attack.
> They were using WhatsApp which promised to not send their data to Facebook.

I've seen that mentioned before, but where does it say that? On WhatsApp's ToS it says they won't share WhatsApp data for others to see on Facebook, not that Facebook itself wouldn't use that data.
I hope one day you can see the irony of your comment.
People who try to study the evolution of well-being (for various definitions of it) show that it stagnated (best case) or started dropping with the generations born in the 60's and 70's. So obviously nothing improved life in those years and decades which follow space exploration.
I've written code for pay for over two decades in a variety of languages and on a variety of platforms. I can say if I don't wish to write code into a Google Document, nothing misguided about that. Someone fresh out of school, maybe, even then, most coders are using an IDE all day or have another window or terminal open so we can do a quick compile sanity check so even for a new coder fresh out of school, this makes no sense.
My greatest fear is that space will become the playground for the rich and powerful where the rest of humankind is left to suffer on an overpopulated, polluted Earth. We as a society can't live on the kindness of individuals to achieve a better future and that goes double for leaning on SpaceX and Elon Musk. They are a for profit venture and that means unless you're rich enough to pay your way then you have to pay with labor which may or may not be pleasant. I know it seems silly to imagine the future like that but the way the rich and powerful have been running the world so far I can't see them giving a flip when they can have safe, sanitary habitats in space which separate them from the existential threats on Earth. At that point they could just say "fuck it" and cut the rest of humankind off from space easily with threats of asteroid bombardments or worse.
My dictionary defines "critique" as "a detailed analysis and assessment of something." That is not what I'm seeing here, nor is it what I'm arguing against.

I have no problem with people arguing against SpaceX's Mars plans, either on the basis that the plan is infeasible, or that he should be doing something else. I have a huge problem with people arguing against it on the basis that the commenter doesn't like it and the whole idea is dumb.

I just want to see an intelligent conversation.
> Dismissing a company because one engineer there is bad at interviewing seems potentially short-sighted.

I keep hearing about a shortage of quality talent in the industry. Given that, I would expect employers to pay particular attention to putting their best foot forward in interviews -- since interviews work in both directions.

One that fails to do so -- or whose best foot is off-putting -- is revealing that their attitude toward potential hires and/or their ability to offer a good working environment is poor.

People talk about how a bad hire is a significant cost for employers, but taking a bad job can be a much bigger cost for the employee than a single bad hire is for an employer, and quite worth avoiding.

Yes.

The amendment clarifies the boundaries of habeas corpus.

These boundaries apply only to particular people - namely those people with recognized US citizenship.

First, most of the human rights abused by the United States governments are non-Americans to begin with (let's put aside the penal system and some very sordid history with suppression of domestic civil rights groups for a second).

The amendment clarifies that foreign targets have no right to habeas corpus, a trial, to know even what they are being held for, etc. A very large contingency of innocent people suffer through this, but this isn't the comment to expound on it.

Second, the US can revoke citizenship of those it deems dangerous to national security (people like Snowden among them).

Take for instance the first result from searching "revoke citizenship join ISIS": http://www.foxnews.com/opinion/2015/01/14/paris-lessons-us-m...

The criticism of the amendment is that the boundaries drawn do not respect the rights of "people" - only the rights of those for which it is convenient to respect (less than 4% of the people on Earth, and no serious dissidents, whistleblowers, etc).
The more I look around, the more I'm opposed to that concept.

Sure, I've seen humans change - but only under heavy "brainwashing", i.e. internalizing an ideology that values being fair, helpful and truthful, and that only holds with a support structure of adherents. And I doubt it scales.

If you look at the world, a lot if not most changes for the better are technology-driven. Technology alters the economical landscape, which makes people do things better, even though they're still following the same behaviours as they always did.

TL;DR: I think individuals have much less agency than we'd like to think.

You should be able to write code with half-busted crayons on the back of yesterday's newspaper, also. But it's much classier (and time-efficient) for all concerned if the employer provides at least ballpark-adequate tools upfront (meaning at the very least an editor that doesn't overtly work against you -- like Google Docs does).

I'll be fascinated to see what Mass Media ideas come through YC. It's pretty obviously a problem, but I've honestly got no ideas at all about how to solve it (although, to be fair, there's a non-zero chance that the media has always been a problem of this magnitude, but the internet/echo chamber culture has simply exposed what was lurking all along).

The upscaledb FAQ indicates "it is not yet concurrent; it uses a big lock to make sure that only one thread can access the upscaledb environment at a time".

InnoDB is designed for concurrency (using MVCC, granular locking, etc) so I'd expect it to be slower at single-threaded workloads than another engine that skips all that.

Only using single-threaded benchmarking is a bit misleading, imo. This is mentioned in the article but only in a small bullet point towards the bottom.
