Ask HN: Could ships that convert CO2 + water to natural gas save the planet? 
DISCLAIMER: I know basically nothing about this topic. It's just a (naive and
likely stupid) idea that woke me up this morning. If anybody knows where to get
more info, or how to answer some of these questions around feasability, I'd
love to hear it.

# IDEA

Imagine a ship sitting in the middle of the ocean (where little life naturally
occurs), with an eSolar [1] installation deployed.

A giant array of mirrors, individually small, but in total much larger than the
hull of the ship, automatically adjusts to keep an intense beam of heat focused
on a boiler, even as the ship rolls in the waves.

Convection carries water from the ocean to quickly cool the boiler and keep
pistons that generate electricity firing.

Generated electricity is used, along with water and carbon dioxide, to create
CH4 (natural gas) and oxygen, at 80% efficiency [2].

Once the ship is full of natural gas, it folds up its solar array and sails
to the port where the bid for natural gas is highest.

I haven't done any math to figure out cost, but it seems interesting/compelling
from a high level. What do you think?

Anybody who wants to take this idea and execute on it should feel free to do so
without reserve. I claim no ownership to anything. Execution is everything.

That sounds a lot like the Intents system on Android (and the web version, http://webintents.org/)
Whenever we made offers to students who hadn't yet graduated we all made it very clear that they are free to interview and accept other offers and we should be prepared for that situation (not in any particular way, but mentally). They didn't owe us anything.

Of course we made attractive offers to candidates we thought were a great fit and where we thought that feeling was mutual. and we never had a candidate accept and then take another job.

to mathattacks points:

- You are young, and your career will be long.

- No one is going to blame you for looking out for yourself.

- No one is going to go out of their way to black ball an anyone over an entry level position. You are not that special.

- strong developers have the world by the balls. There is no reason to play loyalty to someone who isn't even paying you. It's time to get yours.

If it were me I wouldn't have accepted the offer. Assuming you are graduating in May, it'd be way too early for me to make a commitment. But thats me. However, it wouldn't weigh one gram on my conscience if I accepted the offer and kept interviewing to find a better fit. I'd probably use the offer as a bargaining chip.
I think it's all the people with 3GS's plus new customers jumping on to the iphone and more carriers. Numbers seem to support that.

I was on a dumbphone contract on verizon and waited on the iphone 4 until the 4s was released. Personally I wanted an iphone and would have bought on any form factor they released
There's a certain mystique specific to the guitar, it seems...or there's a billion more guitar players, perhaps?
I think it's awfully premature to go around judging who is 'the bad guy', and that it's quite possible both or neither of them have done less than stellar things. But we simply don't have more than a smattering of facts from one side.
Ah, I see now. Thanks.

At least that's one way to do it in ruby.
I agree. It may have some insight, but doesn't really contain a lot of substance. Doesn't emotionally resonate with me... it's like a teacher telling you to behave.

Great. I will forward your post.
Jerf, just curious, but when was the last time that you left Brighton and spent time in Downtown Detroit outside of a sporting event?
Every release of new free classes from Stanford or MIT just makes me giddy and jealous of everyone that goes there. A lot of extra work goes into these classes and I think it says tons about the awesome ideals that these institution holds, which is very different from the ideals that the education system I have been fighting for over half a year holds.
In the last bubble individual companies might have blown through a lot of money, but at least many of them developed really cutting edge stuff in the process.

That's a very good point. While there were some standout companies that survived the first boom and bust (e.g. eBay, Amazon), what really made an impact was the technology that was left over when the dust settled (e.g. online maps, mp3, online trading, better browsers). When the dust settles on the current boom and bust, we will have seen basically iterations on the same theme: niche search, local deals, and social networking/sharing.
The meme that "the rich get richer, while the poor get poorer" means that today, the poor must have a worse situation than ever before.

So let's do a thought experiment: suppose that you can choose to go back in time. You can enjoy the 1% level of income at any point in history prior to, say, 1950. What era will you choose? Do you want to go to 1950, or some point in antiquity, or stay with your current income in the present?

Remember, even in 1950, there are no antibiotics, for practical purposes, civil rights are only slightly better than medieval levels, and so on. You won't have access to instant communications, and only through difficulty, to the greatest works of art, music, and literature. And so forth.

So, if you don't want to go back to those times -- even at the top of the economic heap -- can we really say that today's poor are finding their plight worse and worse?

What would you say if this person's technology contribution was fundamental to the success of the company and, once complete, the other partner then did away with the technical mind behind the product so as to maximize benefit for himself? You have no idea what the true and complete facts are behind this guys story. Stop running around trying to apply half-baked, two-bit Valley Web-startup rules to his situation.
I would love to see a "push" mobile feature to notify you when people you follow change their mood.

Ah, gotcha. This article (http://online.wsj.com/article/SB1000142405297020340550457660...) references a Credit Suisse analysis that says "Apple got $632 on average for each iPhone sold in its most recent quarter..."

At that number, we're a little over $2.5 billion. Staggering.

And while these 4 duke it out a new competitor will emerge and change the game completely.
I agree that he deserves credit for building it into a real business, and he has been richly rewarded for that. However, everything - the company's name, its business model, and much of its intellectual property were my contributions. A large part of its success resulted from sales of products using my technology. The personal falling out was over a woman, and I did not leave voluntarily. This company was my brainchild and I would have continued working under the worst of circumstances if allowed.

Finally, I don't think that anything entitled them to attempt to extort me, or to use my intellectual property while in breach of contract.
It looks like Microsoft is trying hard to pivot and be that competitor
Thanks guys, I'm jumping right into it.
This is fantastic! Emergent commenting behaviour gave rise to unexpected structured information.
Hard to believe anyone would use that as an example. In C# you could do:

filteredArray = allRecords.Find(i => i.someField == filterValue)

EDIT: Not sure why the downvote, I'm simply stating that many other languages have far better syntax for filtering an array so I'm not sure why the author would think the syntax in Obj-c is all that great unless they have never done the same thing in any other language.
Amazon has been launching imprints for the last year or so, including romance imprint Montlake Romance, thriller imprint Thomas & Mercer, and most recently sci-fi imprint 47North. Nothing new here, this article has been a long time coming.
My first thought is that this is probably more expensive than building a solar array on land and connecting it to an electricity grid. Although potentially a ship could spend the northern summer in the northern hemisphere and then go south for the northern winter, gaining access to more sunlight.
20% of a start-up (at year 1) is worth much less than 20% of it 5 years later. If the company had their paperwork in order, the OP should have maybe 5%, due to vesting and dilution. Or the original investor should have bought him out for a few thousand, as he was walking out the door (but he didn't did he?). Imagine if you had worked on building your company for 6 years, only to have an early employee (who presumably quit in a huff) come back and demand 20% - which they were meant to actually work for, and asserted IP rights on everything they had worked on.

That said, the company is also behaving very badly, what with the extortion thing. They would be better off making a reasonable offer, and hitting themselves on the head for screwing up their ownership / IP assignment paperwork.
Back in high school in the early eighties I played with a bass player who had a Peavey amp and right in the middle of a concert something exploded and his 4 speakers all blew out. Luckily there was another guy who could loan his amp but our bass player was pretty upset (and broke) so I offered to try to repair his amp and we all chipped in for new speakers.

Anyway, this guy had a bird and its usually open cage was usually on top of the amp, which had a ventilation grill on top. When I opened up the amp it was full of bird poop baked onto everything. I like to think the poop had something to do with the failure because I really like Peavey stuff in general. After a thorough cleaning it didn't take long to figure out that the filter caps after the rectifier of the power supply had blown and a huge 50Hz (Germany) ripple was sent out to the speakers.

I got some caps with more margin (the original parts only had 3V of margin over the worst case expected surge) and with the new speakers we were back in business.

Fast forward 30 years and I'm now a bass player myself and I have to say that Peavey is still great for budget gear, especially their basses. Of course there's really nice budget gear in general now, due to China and the general downward prices on electronics.

I go to a country jam now and then and the bass player there has a ton of vintage gear (he's pretty vintage himself) but for everyday playing at the jam there's of course a Peavey combo that works great every time.
A slight nitpick. Your definition should be a number whose proper divisors sum to the original number. Or it should be whose divisors sum to twice the original number.

World Is Facing A Wave Of Cyber Crime
But when you dilate time 50 times, isn't it still interesting? Aren't the precise parts still precise? It's more interesting fast because the material properties change, the speed of the springs and the motion of the flame front becomes important-- but that's still fascinating even when you can watch it happen.

And you don't have to slow anything down to see that; controlled demolition, say, deals with the same sort of stuff on a large scale. When you're blowing up a building, what's happening in an individual explosive (hand packed fuel in a canister, with a dumb fuse...) too fast to see isn't important, but you need to pay close attention to the things that happen during seconds, perfectly human timeframes, because they become interesting and complex.

Watching a single revolution of an engine in slow motion, you witness a marvel of engineering taking place before your eyes. But for decades (centuries?) before we understood them, people built engines by trial and error, and watching one of them in slow motion would not have been impressive. It would look sloppy, imprecise, unrefined. Engines today are amazing precisely because they are well understood very slowly, and in practice it mostly works to just say "and then that happens over and over again and that's what pushes you forward."

That understanding is obvious on every scale, whether you're watching high-speed video or just hearing the engine note from outside. That's why I say that the interesting things are still interesting slowed down, and that "it's so fast!" is a red herring.
Huh? Obj-C only uses @ signs at a couple of places, like to denote a native @"dasdasda" string and in compiler instructions...

Inferring from very little information you've provided this sounds as if the Corporation did a licensing deal with the LLC to acquire the technology. This would be one way for your former partner to cut out out of any equity up-side for the going-forward business. Scary stuff. You need a lawyer.
Re: A vs AB.

The difference is the fundamental mode of operation with different distortion characteristics. Class A amps will have both odd and even-order harmonics but class AB will be mostly even-order. That is both an audible and and electronically quantifiable difference.

If you are talking sound reproduction then A vs AB is insignificant because you only see the difference when the amplifier starts distorting. If you are a guitar player who drives an amp to distortion as a matter of course this difference is germane.

There's an implied assumption in this post that handling edge cases or one-off, extreme cases necessarily is done by writing ugly/dirty code. I think the whole point about writing clean code is avoiding the hacky stuff even if the problem is messy. We're in the business of articulating solutions to messy problems clearly enough so that they can be executed by a machine. The best professionals in our field do that, and also make it so that other people can read and understand their work. That's what clean code is to me.

Admittedly, there's room for interpretation and a degree of subjectivity here. However, this doesn't prevent us from knowing about what dirty code is and I don't see a compelling reason why we ought to tolerate it (e.g. long functions with a lot of branching are difficult for everyone to read, so you shouldn't have any of those; same goes for badly named variables/functions/classes).
Because Java is designed by committee and this is a bike shed issue. It's so simple that everyone understands it and thus no progress can be made.
The magnets would have to be so strong they would be dangerous to work with.

The easier way is just weld rods on to pull a dent out with, and then chop the rod off. There are several dent pulling tools that work this way.
> Whereas in other languages you'd have to write... "."?

You write "." AFTER you've written the method name. In ObjC "[" immediately tells that you want a method/class name for autocompletion.

And that's the reason, reading story after story about the big 4 on HN is getting so boring to me. No doubt they make amazing products, but these are giant corporations now. Siri, G+, Timeline, Kindle Fire are all fascinating products, but they don't excite me nearly as much as a simple app made by a fledgling two person startup.
You clearly aren't trying to be anonymous, since you named the company and your patent is easy to find. Congratulations, I guess, for being the first to patent the idea of authenticating a web app based on a password plus a cookie from a prior session, and requiring additional authentication if the cookie isn't there. Hard to imagine that that wasn't obvious in 2004, but maybe it just seems that way in retrospect.
If I were a betting man I would say no. The primary reason would be Nuance. Something like Siri could be viewed by Nuance as direct competition against Dragon.

The questions are answered in the article. The equivalence is not supposed to be obvious even to other number theorists. Most of the article is devoted to explaining "why" it works since the actual proof is two paragraphs.
On three times as many US carriers though. That's quite a bit of a difference, given how carrier-availability seems to dictate phone purchases in the US.
What portion of what is given to who is likely up to a judge and lawyers to decide at this point. Unlike HN, they'll have most or all of the available facts, which is likely to aid them in coming to some sort of agreement that's fairer than 0, which doesn't seem a reasonable amount either.
Oh yeah, the iPhone 4S is such a flop. Obviously, the lack of a new teardrop form factor is totally sales and Apple should recant from their heathen ways and do the smart thing, like the other mobile phone manufacturers.

One wonders where Technology mags find all these seemingly countless analysts who deride every iPhone (or at least are unimpressed)...
The first thing I would do is remove all references here to the names of the companies involved.

You can still get the benefit of Hacker News advice while keeping the parties anonymous... but by naming everyone, you open up several cans of worms (they could sue you for defamation, they could learn how you're thinking about this and what your resources are, this could get posted to TechCrunch in a way that hurts your chances of a settlement, etc.).
Totally aside from what "feels" and "seems" good or bad, the only relevant question is whether OP kept their shares or not when they left... this should be the only point they have to prove, no? And what about the patent? Was that bought or licensed from them? I think we are lacking the important details, namely what happened when they left the company and what they signed then and before.

So it comes down to what papers were signed when by who and do you still have copies? If all you have as proof is "word of mouth" without any witnesses then, well, you might be fighting a lost cause.

These are not simple problems.

If we consider labelled trees then this question has any easy solution: there are labelled trees on n vertices. Counting the total number of graphs on n vertices is even easier. However, no closed form solution is known for unlabelled trees and this problem has been open for well over a century.

Hmm, any node can be a root node which is tricky, but not show stopper. A root node can have 1 to N-1 branches not so bad. You can order them by some sort of weight with each leaf being (depth * 2N)^N so they are strictly ordered, still looking good. But, how do you count mirror images. AKA a simple star with a center point and N edges just counts as 1.
It's in the bar along the bottom. Very similar to Textmate.
Icelandic data center run on 100 percent renewable energy
This reminds me quite a bit of Green Freedom, a program out of Los Alamos which created gasoline out of atmospheric CO2 and H2O with some catalysts and an external energy source (they used nuclear). If I recall correctly, the gas would have cost around $4 a gallon, making it not quite competitive with gas where I live in Denver assuming you don't count for the externalities. When I get to work, if I remember I'll see if I can find a link and post it.

I think it was a post on HN awhile back that got me thinking like this. If I don't want to do it, and the opportunity cost for me is greater than the cost to hire someone else to do it, then I should just pay them. The key here is the opportunity cost is for me, not for anyone else. For example, I hate mowing the lawn and I estimate I'd have to be paid well over $100 to get me to "enjoy" doing it. Thus, I pay the $60 for lawn service. To me, I just earned $40 of my time back. Now, I'll admit, it isn't as cost effective as being cheap or "frugal", but I do think I enjoy life a bit more.
