To be fair, "learned to land" and "did successful landing once" aren't the same things. Similarly, "USA landed on the moon" and "USA now has a capability to land on the Moon" are different things.

And SpaceX will get from here to there faster than the government.
Considering that the release notes mention " * OS X and NetBSD support improvements", fears of it only running on Linux systems, let alone only Linux systems with systemd, seem rather unwarranted.

Joking aside, I wonder if it's possible to write a real-time webapp with C and CGI. Ok, 'possible' is a strong word; but I'd really like to hear from someone who'd given this a try.
Perhaps you're right.

That said, you can certainly buy a cell phone separate from a contract in the US.
The problem is that using a parachute means that--assuming your launching from Houston or Cape Canaveral--you're only going to be able to land in the ocean. With just a parachute, can you recover the booster and make it launchable in, say, a day? That's kind of the goal: to make rockets more like cars and less like soda cans, i.e. to reuse vs. recycle.
If you're genuinely interested in some discussion pertaining to the answer to that question, use your favorite search engine to search HN for likely phrases and skim until you find some discussion with a significant volume of commentary.

Because of its political nature, this is a topic that's best not discussed unless you have some very specific questions or observations, and you are already very well informed about the merits and faults of both the systemd project and most of the other pieces of software that provide similar functionality. :)
"Socially awkward" seems to be a loaded term in your use case. If you are "socially shy", then yes reading would help. But in the case you're not socially awkward in your natural environment (ie you just lived in a different culture), the nuisances are impossible to learn unless you encountered it. Just think of it as a different culture, no East Asian will come to the US without fucking up something small or big a few times, and vice versa. Same for people of different classes.
No, they really aren't at all. The difference between a rocket that can reach 100km and 200km is tiny. The difference between one that can reach 100km, and a 100km orbit, is big.

They got several probes onto Mars. That's just off the top of my head, though. The Soviet space program was no joke. Though it may have been a combination of brute force and revisionist history over their failings. I personally suspect there are a lot more human corpses in orbit than anyone knows about.
Blue Origin has actually been around longer than SpaceX. Both companies were also rans of the first XPrize.
It sounds like Blue Origin rockets are only capable of sending payloads to space for just an instant, before gravity pulls them back down to earth. They're nowhere near close to capable of putting anything into orbit.

Is that correct? If so, what are they good for?
I like it :) Stable, wealthy parents as a service. Uber for upper middle class upbringings.

ive got a Surface Book and I don't think I'll ever own a Microsoft product again. AUD$3000 for a laptop that bluescreens while browsing the web.
If it's a pissing contest that accelerates the rate at which we progress space travel and technology then that's fine by me.

Also I feel like perhaps you're underselling their achievements here, it's still impressive and it's still incredible progress in space travel.

Good luck to them both.
And even those who party all the time might be able to finish with the best possible grades.
They landed probes on Venus that sent back photos. No one else has done that. And it's not the easiest thing given the surface temperature is 462C.
Space tourism.
Yep. My flytrap won't trigger its petals until you poke it twice with a toothpick in the same general area. I think it does this for numerous reasons.

1. If the petals close and they don't actually capture anything, they take hours to open back up.

2. If they do close on something, (for example a fly or a spider I happen to come across) they will stay closed for days digesting whatever is trapped inside. The traps themselves don't actually survive this process. They wilt away and new petals grow to replace the old after a month or so.

Speaking strictly from a natural selection point of view it make sense that a plant that has evolved to derive it's nutrients from carnivorism really has no chance at surviving if something as simple as a leaf, a seed, the wind, or any other poor nutrient provider could trigger it to close on said object (or not on said object). Either way, a plant that is in such need of nutrients can't really optimally survive if it closes at every opportunity it might have food in it's trap to catch.

Natural selection seems to suggest that a venus flytrap that is more precarious about when to trigger it's trap is the far more optimal survivalist when it comes to these plants.

I should also point out that calling them a flytrap is kinda lame considering their trap mechanism is not really all that fast enough to trap most flies. Atleast not in my observations. Although I have discovered that they get lucky from time to time, their trap mechanism is also apparently evolutionarily optimized to avoid most bugs that just land, chill for a minute, and fly away. Bugs they wouldn't likely catch. They would rather wait for a caterpillar, spider, beetle, etc to cross their path.

My pitcher plant is the real fly catcher. It uses the old fashioned, "oh hey thats a nice smelling hole. I wonder what yummy things are down there for me and my maggot babies to eat. Dooo da doo da... eh... feets sticks to pitcher plant's trap oh no... AHHH! HELP! SOMEBODY HALP MEEEE!... HELLO?! Isn't there anybody out there!?

,,,

ohhhh pooo. Well at least it still smells wonderful down here." technique.
They were also pioneering in the space station/space habitat arena. We have the Russians to thank for a lot of the technology aboard the ISS, both when it was being built and to this day.
I misunderstood. To say it is a "distribution problem" read to me as if distribution was a verb: that is to say "everyone could have what they want if only the means to move people and things around were available".
Once US was landing on the moon? What kind of achievements you'd like to have?

Planetary probes, like Lunokhods - several weeks of Moon exploration? Or Luna-16 - automatic probe which brought lunar soil to Earth? You can say that's less impressive than Apollos, and I'd agree, but that still different things - which USA couldn't do at the time, and those programs had some advantages over Apollos too. Or a series of Venera probes, including landers? Mastery of automated docking? Orbital stations - starting with Salyut-1 - with myriads of experiments (medical, industrial etc.)? Rocket engines - more advanced than American ones by such criteria as working process (gas-gas was tested during 1960's in RD-270 with single chamber thrust rather similar to F-1), Isp and mass ratio (NK-33), total thrust (RD-170)? VEGA comet fly-by?

By which criteria these don't count?

You can get much farther by storing a fraction. Still, a midpoint is not the most effective point to chose. One solution I've explored is in the form of fractions generated by the Stern-Brocot tree. The continued fraction representation is easy to work with and can easily be turned into other representations.

With that, you could pick ideal points between bounds very cheaply:

(1/4, 1/2) → 1/3
(4/3, 5/2) → 2/1
(5/4, 7/5) → 4/3

In languages with large integers, it's quite easy to store two numbers. In a language like JavaScript, 53 bits of the mantissa in a double floating point number give 70+ moves [1] before you'd have to worry about losing precision, and if that were a deal breaker, a continued fraction is very cheap to store instead.

If people are interested, I'd be happy to share some implementations I've got in a number of languages including Erlang and JavaScript (I'm rewriting these from a prior version I did which used a slightly less optimal path representation).

[1] These are worst case. Most interactions could survive 1000+ resorts in practice. I've yet to see any of the components outgrow the 53bit mantissa of a double in JavaScript. The worse case grows with the Fibonacci sequence which is easy to see once you learn more about the Stern-Brocot tree structure. Even when they do grow large though, it's easy to switch to the continued fraction representation which solves this problem.

EDIT: Here is a short list of indices from a production database where it's easy to see why fractions are far superior to floating point indices: https://gist.github.com/strmpnk/d4afe4bb5bb69b46631b
I honest-to-goodness don't understand. Why not just let the preference remain forever?

Yes, I've been following this issue closely. Nick Cameron is working on a revamped macro system that will replace the current compiler plugin system for the purposes of syntax extensions. It's probably still gonna be a while, unfortunately, since it'll take some time to get that kind of stuff vetted and baked into the language.

Here are some recent posts by Nick on his experiments and progress (in order of publication):

* http://www.ncameron.org/blog/procedural-macros-framework/

Pretty much all of his recent blog posts are on the topic, so it's worth browsing through all of them if you're interested.
Talking to random women is difficult if you're a guy. There's a very blurred line between being friendly and flirting. Flirting is often awkward, and people don't want to create awkward situations.

I suppose some guys can do it well and enjoy it, but I don't.
Actually a Venera lander was the first and only (so far) which returned a picture from the surface of Venus. Brilliant engineering imho. Not to mention the MIR space station.
They must be talking to Japanese or German companies. I suspect German.
There are lots of guys like that around here unfortunately and seems to increase every year :/
Could you share a link to the YC reading list 2015 . I'm surprised no one asked.

For the same reason Facebook puts a big loud warning in the developer console. People will follow any instructions they're given. "Press ctrl+shift+I and paste this in the box and you'll get a free puppy" "Put this in your address bar and your crush will be revealed" "Go to about:config and double click this thing, and then click this link and we'll show you nearby singles that want to hook up"

Firefox add-ons essentially have full, unrestricted access to your computer. Locking this down good and well is pretty important.

I love that Neil deGrasse Tyson quote, "Asteroids are nature's way of asking, 'How's that space program coming along?'"
I am a hardware engineer with a lot of software experience to go with it. I have had no work since the "crash" in 2008 when I was 58. Since then no company even returns a "no thanks" letter.

However I must admit there is a lot of karma involved. When I was 30, head of engineering, I was responsible for hiring a total of 30 to 40 engineers. I would have never hired anyone at my age. I didn't even think about it. It just seemed obvious.

So I tell people I am retired, which means I'm old and unemployed. Like others in these comments I am continuing to work, but only on FOSS projects, like the Atom editor. I can now sling full-stack code with the best of them and I figure I could for 10 or so years. But there is no hope of gainful employment.

the problem with PGs essay was that it is full of strawmen and non sequiturs made up by him. For example, the sentence you just described. Let's attack poverty - what does that mean in practice? in practice, that means spending money on solutions to poverty, ala Sweden. Where does that money come from? from taxes. So, the conversation about raising taxes on the wealthy ( or "attacking wealth" as he says ), outside of a very small fringe, is just really a conversation about raising funds to attack poverty. And PG made it sound as if the conversation is about attacking wealth for its own sake, which nobody but the fringe is having
What's great about Blue Origins long term is the frequency of launches. Blue Origins will be launching a rocket every day years before SpaceX will, because of obvious differences in rocket magnitude and mission.

There's a fair amount of boilerplate that comes with launching a rocket. From the command terminals (and associated IRL command structure) to the pod's parachute and rocket assisted landing , all components will be used and tested A LOT thanks to Blue Origins' strategy.

Assuming Blue Origins learns as much as possible and iterates on any sliver of weakness, we as a planet can be far more confident in the human carrying structures that are used to transport space-to-surface. SpaceX undeniably has more impactful and impressive rocket technology, but I'll always respect the lower level work Blue Origins is focusing on.

Space is really, really, really hard. Everyone wants to go up, I enjoy how much Blue Origins wants to come back down. :)
Well, USSR had a really hard time with Mars landers. AFAIK, they got just one landed - and it stopped working shortly after that. But that one landed before Vikings.

They're a smaller-scale test platform for figuring out how to do propulsive landing and re-use, similar to SpaceX's grasshopper rockets. Blue Origin is also developing an orbital rocket, which will hopefully be more impressive.

Somewhat sad to hear it. When I was working on my startup, we got our start on Dotcloud. We ended up migrating mid-stream to Heroku, which was more expensive but ultimately better designed and faster at progressing.

But it's been gratifying to see that the original team found a very potent niche in containerization. It's kind of funny that Docker is now probably the hotter of the two companies.
I'm going to get downvoted, but ...

I can't believe that a technically savvy group like HN readers would even entertain the ridiculous idea of levitation or flying saucers. There is nothing mysterious about magnetic forces. They have been understood for a century. And obviously flying saucers are a myth or we'd have evidence.
I'm going to bookmark this for all those times I have no better way to explain this to someone. Very nicely done video.
Yes. A much better approach would be for all the shareholders of the company to elect a group of experts to periodically review Larry's ideas and sign off on his major capital outlays. We could refer to these people as the "Board of Directors".

Sure, what I think Oracle does better is it provides a lot more flexibility with how you can refresh your materialized views. Oracle has 3 ways that I know of to refresh materialized views; complete, fast, and partition change tracking, furthermore Oracle allows you to refresh on commit instead of have to manually do it or schedule a job to do it.

Although it has nothing to do with materialized views Oracle also has a built in scheduler, which can be used to do periodic refreshes (hourly, nightly, etc). You can achieve something similar with postgres by croning a SQL script.

To my knowledge postgres doesn't really have these things (other than in 9.5? you can do refreshes without getting an exclusive lock like in 9.4), although I could be wrong. I just wish Oracle wasn't so expensive.
Yes money solves lots of problem and fixes all sorts of bad decisions - much like how a marriage is fine until unemployment hits.

I agree 100% that there is a need for different management approaches between foot-to-the-floor growth and surviving hard times. It is a rare person that excels at both. Having lived through both, I am better at the later, but the former is much more fun.

This looks like a very complicated engineering achievement that undoubtedly will lead to advances in space travel and tourism.

That said, I didn't get to watch the launch and join in its success or failure, so I'm finding it difficult to actually care as much as other launches.

> ...when has it ever been socially cool to literally be rural "trailer trash" in America?

You're the one calling it trailer trash. Even educated poor people often speak in a more genuine and direct way than elite people do. It may sound funny to a fancy person but that doesn't make it trash.

> ...no one checks your papers at the door.

Yes, they do. Every job, startup accelerator, and VC checks your background. Elite VCs fund elite founders. Elite founders hire elite managers. Elite managers hire poor people to do the actual work. The order is maintained.
I just learned about the SJW yesterday (yes I'm out of touch on the web). They must be going absolutely nuts over this decision. (I am not expressing an opinion on anything).
"Most of the time, potential founders who share my background tend to work at lucrative jobs in finance or tech until they can take care of everyone in their families before they even dream about taking more risks — if they ever get there."

This is so absolutely on point.

I've been through life, until now, with exactly that feeling, expecting but not knowing that others feel the same way.

I've been in a bit of a rut recently, and this gives me some ammunition to get myself back together... so thank you for quoting, and thank you, author.
This would be so much more useful as a C library. I'm just "over" the whole all middleware uses the JVM trend. I opened it thinking I might check if they had a RethinkDB adapter and maybe write one, but I just can't muster the desire to even download a big Apache Java project and unzip it, let alone try development on one.

Anyone got an Apache Calcite alternative they want to recommend?
So could we then say based upon your comment and the parent that a meritocracy is antagonistic to diversity. Not trying to be argumentative, just more of a thought exercise. If a meritocracy chooses the best, and the wealthiest tend to have the resources and opportunity to make themselves better, then always choosing based upon merit means favoring less diverse backgrounds. Additionally, we tend to always view ourselves as ‘having merit.’ So we will also be predisposed to choose people like ourselves further hindering diversity. I personally have always favored the idea of being meritocratic, but am also leaning more toward purely favoring diversity, not diversity of superficial attributes, but the diversity of peoples background. I feel it helps to expand the breadth of knowledge of the team and avoid blindspots.
Why wouldn't it be?
Wallabag on Sandstorm is an interest of mine as well!

I did look at it a little bit a few months ago, and decided it wasn't a weekend project for me. It took me a little bit to rediscover why, but I think something like the current doc on [Network Access][] is what discouraged me: "By default, Sandstorm runs each app instance with no network access ... Supported protocol: SMTP (email), Other protocols: Work in progress."

Rich people network and want their kids to be successful, what a shocking revelation, so different from us poor people.

There is a similar effect with tollways. People often have a choice between using the tollway (and paying the toll) or taking the public roads and sitting in traffic.

I don’t have the figures for the USA, but here in Australia the rate people empirically use to avoid tolls is $12 per hour (i.e. they will sit in traffic for an hour extra to save $12 in tolls). Assuming people apply the same thinking to ride sharing, then a cheaper competitor with worse coverage should be able to capture a reasonable share of the market.
