Yeah, no one else has made any announcements wrt re-usability. It seems odd, but I guess that's why they call it "dino-space".

Ariane 6 seems to be in response to the SpaceX challenge, at least; they aim to halve the cost per kg through cheaper and common upper/lower stage components. Which is good, but still not competitive with F9, much less a reusable version. At one point they almost made it all-solids in the first two stages, plus boosters, which would have totally doomed any future attempts at re-usability. The final design uses a F9-style common component liquid core, so they could maybe do the same thing as SpaceX later. They are still stuck with solid boosters, though, in a pork-provision move for Italy.

I've got to imagine that ULA is quietly looking into it. But it's quite possible they're just hoping SpaceX will eventually implode of its own internal contradictions and they can go back to their nice little government-launch monopoly. Or maybe they've decided they can't do it without absurd expense, based on their internal development costs. Or maybe they just hope to coast on their existing contracts for a while, and deal with it later once SpaceX has taken all the lumps.

NASA, via SLS, sure isn't looking at re-usability anymore. Lower cost to orbit via research should be their main task, if you ask me, but Congress would rather have them fly giant rockets a couple times a decade, apparently.

The Russians, well, are not much into changing things up. (They've been running Soyuz and Proton, their current launch families, since the sixties!) And their recent aerospace development programs have been less than impressive. But they have a real industry to protect, so one would hope they have a strategy.

I think that everyone's waiting for SpaceX to make it work, and then they'll get to copying. My long-term guess is that this'll kill several of the incumbents, a few will make the transition eventually, but most of SpaceX's competition will come from new entrants. In the meantime, SpaceX will be free to reap the profit from the margin between what it costs them and what their old-fashioned competitors can do. And/or capture the whole darn market. And/or grow it with lower prices. Maybe all of the above.

Perhaps, if an "Einstein" were to run the economy, state ownership of the means of production, and central planning, would be workable. The problem is that eventually the "Einstein" would perish or be replaced, and the lesser replacement would be a disaster.

There is nothing preferable in a few oligarches (or plutocrats) running everything as "the government", to capitalism. In fact, at least capitalism is somewhat distributed, and capitalists have a vested interest in pleasing their customers. Not so with government!

I'm a huge admirer of Einstein in general, but in this he was far outside his area of expertise!

>No white person in their right mind would honestly prefer to live in a half-black community over an all-white community.

Well, some do. In their right minds et all. And could not care less about such racist BS. Except if you mean that the black neighborhood is poorer and less developed, so they might prefer the richer one.

Here's a well known example:

[Johny Otis] grew up in a predominantly black neighborhood in Berkeley, California, where his father owned a neighborhood grocery store. Otis became well known for his choice to live his professional and personal life as a member of the African-American community. He wrote, "As a kid I decided that if our society dictated that one had to be black or white, I would be black.
The intent of Hacker News is to be news of particular interest to the "hacker" (defined in a somewhat unclear and unusually broad way, but still) community, not particularly news of general interests that is of interest to members of that community for generally the same reason and to the same extent as of the more general community.

There are plenty of other forums with different intended purposes where such discussions are less ephemeral than on HN.
Maybe mass-market software will no longer be a profitable category of software in the future. I don't see that it would be such a tragedy to have to use good-enough commodity word processors or image editors.
But if the consumer can't choose their price, then the market can't work. Usually you have choice between nearly-equivalent alternatives at different prices with more or less bells-and-whistles. But with art, a nearly-equivalent alternative violates copyright, so you can't choose a cheaper alternative, because there isn't one. Because everybody else is banned from selling one.

The answer can't be anarchy obviously, but it also can't be installing spyware on every device to stop copying. The larger public has shown that they're absolutely willing to throw every single artist under the bus in order to free themselves from the shackles of copyright.

The intersection of art and business is somewhat really weird. You're making something whose entire reason for existing is making people feel nice in some way, but it's never an actual physical product like a bar of chocolate. It's an experience. Depending on who you ask, that is either the most important product of civilization, or some useless baggage tying up useful hands. You need to make the former group pay you money. Fortunately, people understand that things cost money and should be willing to pay you a reasonable price. Unfortunately, most middle-class and above people fall in the latter camp, so most of your fans will be poor and for them a reasonable price might be less than what you want to get.

Personally, I have never paid more than twenty bucks for a game.

I am terrified of mental manipulation. My only inclination and direction is to train my mind to be an independent blank slate.

The form of abstract ideas, the direction of thought. These things can be studied.

No offense, but personal anecdotes are not evidence. If you are sincere, and you could be for all I know, it should be easy and desirable for you to produce factual information or documented sources that supplement your story. Otherwise, we can't take this as credible evidence.
>To choose one category of crime, blacks make up about half of of murderers. However, there are twice as many poor whites as there are poor blacks.

Those whites don't have the same heritage of poverty, bad education and racism against them though. Nor are over-represented by a huge margin in incarceration rates.

>Further, international comparisons suggest you are wrong about American-style "destitution" causing crime. I know many professionals (I live in India) who are far more "destitute" than any poor American (at least in terms of goods and services they can afford). Strangely they don't turn to crime at anywhere near the rates Americans (of any race) do.

"American style" is not just about being poor / destitute and not being able to afford things.

It's about the particular flavor of being that, in the context of the general societies attitude, prevalent climate, ways to deal with it, etc. So people in India being "far more destitute" doesn't mean they share the "American-style "destitution"".
He means that the difference between white and black in america is magnified in comparison to the uk.

They may make up half of all people convicted of murder, but then its been widely observed across many different categories of crime that, on similar fact patterns, blacks are more likely to be charged with a crime and are likely to be charged with a more serious crime than whites.

If you take away sock puppets you take away anonymity as well. Even if you make everyone use their name and face and display pic and ip address and location, there is no guarantee that a group of people will stop censoring another group with or without sock puppets.

If you care to count there are at-least 5 controls on HN or any forum since 1990.

1. What gets on homepage ( Stickies )
2. Admin control
3. Firewall
4. Voting
5. Moderators

If you take social groups into consideration then on HN you have at least

1. Programmers
2. Startup People
3. Technical People
4. Geeks
5. Hackers
6. Security Hackers
7. College Students
8. Academic People
9. Trend followers
10. Trolls ( my people )

These 10 groups fight amongst each other with the help of 5 controls above. Every forum is always like this, since its inception-middle-death.

No one really wins but the constant bickering about forces each group to outdo each other. Whether it is progress or going about in circles only time will tell.

Just because you can patch the fucking software doesn't mean people will change. You will probably add one more control level to make into a total of 6 and then nothing. Some other egghead will write about censorship 3.0

I don't think this kind of analysis would provide any insight there. A simple look at users who have high activity on certain topics would be a good first filter, though.
To block websites on ALL your devices you need to block them on the router level.

If you have a linksys router you can visit http://192.168.1.1 and the default username and password are both "admin". From there you can visit the website restrictions area and add YouTube to be 1 of 4 restricted domains.
Yes we want it to scale, even if it means full nodes run only by large organizations. The benefits of decentralization would be very real and tangible even if only, say, 1000 organizations (companies, universities, etc) were able to host and operate Bitcoin nodes. This would still make Bitcoin clearly decentralized compared to a single company (like MasterCard) processing all your CC transactions. For example Mastercard decided of their own accord to block CC donations to Wikileaks [1] but one of these 1000 hypothetical organizations running full nodes would be unable to do such a thing and block specific transactions.

The number of full nodes decreased in large part because in the early history of Bitcoin in late 2010 or early 2011 your only option to have a secure wallet or to mine reliably was to run a full node locally. But nowadays there are many alternative lightweight clients using the SPV protocol, and a lot of reliable mining pools (it was in mid-2011 that pools started mining more coins than solo miners running full nodes). So of course many users stopped running full nodes.

Its not a top by category ranking of all HN posters, there's a merged list of top commenters and leaders, and then the ranking is from that. Being on the bottom of that (as I am for agreeability) doesn't mean you are still ahead of everyone on HN that didn't make the list.

Well, who said it has to work as a competitive free market merely for any particular and very specific album/song, instead of at the genre level?

Besides, buying it at the artist's asking price has worked for 8+ decades -- for as long as there were physical media.

I find a little bit telling that HN has basically no sympathy for cab drivers, whose job formerly paid a living wage (protected by that reliable bogeyman "government regulation") but whose livelihoods are now under assault from any number of "disruptive" startups.

Not really, you can't actually make new works of art based on old works of art, since copyright forbids that. Technically you can, but they have to have been released before 1920 and that date will never change. You will never, ever be able to use Mickey Mouse in your own cartoon and you will never ever be able to take a sample from an earlier song and put it in yours without paying to whoever happens to own the license for it.

There is a good reason the public sector operates at a loss, it's because it serves the interest of the entire country, which no company can pretend working for.

If for example some bus company operates at a loss and receives public subsidies, it's because it can allow people who can't afford gas to go to a job, which is a net gain for the country as a whole.

While it's true that the democratic process is not always working very well, it's the reason why the public sector is not always efficient. But it's much better than an autocratic system. Democracy is just the least worst system there is.

A company has only inputs and outputs for the sake of check and balances, accounting's only role is to make sure it belongs in a sound economic logic, while a government is a single monolithic machine, often interacting with companies, but for the interest of the citizens.

(I did not invent all of that I heard chomsky talk about "operating at a loss".)

The more important concern is: can this work well starting off? Can you make it through those first three years, and raise additional funding as needed? If you have a strong team and reasonable initial plan, then they'll believe you can figure the rest out with time.
You are being pedantic. I am being sort of humorous.

I think the main gist of my point stands though: Ranking dead last on this list hardly equates to "dropped on your head." That's like saying "I only won one of the less important Nobel Prizes. God, I'm such a loser." Or something.

I suppose it is just like writing exactly the same app over and over again. But in a different Lisp dialect every time. And several of the system libraries are missing, but you never know which ones until you try running the code.
A high thrust-to-weight air-breathing flyback first stage is certainly attractive. Load up a bunch of fighter jet engines on it, and go: no need for engine development or carrying a bunch of oxidizer.

Main obstacle there is that optimum staging altitude and speed are very high by aircraft standards. 100km and Mach 10. Not much air up there. So you couldn't replace an F9-1 like that. You could perhaps use it as a 0.5-stage to get an otherwise SSTO rocket over the hump, but it may not be worth it compared to a standard architecture: still requires a separate giant lower-stage airframe, and one with much different technology from the rest of the system.
I kind of noticed that, though lines(c4x86.c) - lines(c4.c) is closer to 30.

When you consider that many outlets only play $200-1000 for a piece, $2000 is a lot of money. Journalism is not software development.

> But if the consumer can't choose their price, then the market can't work. Usually you have choice between nearly-equivalent alternatives at different prices with more or less bells-and-whistles.

Actually, unless you have competing sources of near substitutes, a market can't work (or at least have the properties that are held to make a market ideal) period; allowing purchasers to set prices against the wishes of sellers doesn't solve this problem, it just changes the details of the failure.

To the extent that works of art are not easily substituted commodities, they simply do not support an ideal market.

> But with art, a nearly-equivalent alternative violates copyright

No, it doesn't, unless its actually derivative. Copyright protects against copying, not coincidence.
Thank you!! Will do that...
That is an _amazing_ story.
It depends on what your goals for your kids are. It also depends on the quality of screen time. Youtube != Programming != Video gaming != Documentaries != Movies != TV.

Personally, my primary goal for my son is not to make him the best programmer out there. I want him to be a good, happy person first and foremost. If there are things I can do to make him a better programmer that would hurt the chances of him being happy and good, then I will probably prefer instead to hurt his chances of being a good programmer.

Screen time is one of those things that I'm somewhat concerned about. Some kids get a lot of it these days. I'm not normally one for fearmongering, but the studies I've seen coming out don't necessarily take a very positive view of its effects.
