Previously there has been evidence of Hydrogen at certain locations on the Moon, though the evidence did not rule out the possibility that it was bound up in rocks as hydrate minerals. Concrete is perhaps the most widely known hydrate, few would regard concrete as a ready source of H2O even though it may be as much as 1/4 water by weight. Other evidence has pointed to actual water ice but not conclusively. This recent paper puts forward unambiguous evidence that there is actual water ice on the surface of the Moon.

That's significant because water ice is an extremely useful resource in colonization of the Solar System. It can be harvested for potable water, of course, but it can also be cracked into Oxygen and Hydrogen, for breathing and use as a rocket fuel.

That last is extremely important because of the rocket equation. The amount of propellant (fueled mass / empty mass) you need to accelerate a rocket to a specific velocity (delta V) scales exponentially with the ratio of that velocity to the rocket's exhaust velocity. Staging lets you stretch this harsh restriction by throwing away parts of your vehicle so that you can clean the slate and get to a better mass ratio for the next stage. But staging is still exponentially costly, just more efficiently so.

Now, if you look at the very end point of a trip to the Moon and back you have a vehicle launching from the lunar surface and then (the same or another vehicle) transferring to a return trajectory to Earth. These maneuvers take a sizable amount of propellant (especially launching from the surface). The weight of that propellant needs to be gently landed on the surface of the Moon, which costs extra propellant. Further, the return propellant plus its corresponding proportion of the landing propellant needs to be boosted from Earth orbit to the Moon, which costs further propellant. Etc, etc, all the way down to the launch vehicle(s) on Earth. As you see, the return propellant imposes an escalating parasitic cost throughout the whole trip. If, instead of the above, you were able to pilot a mostly empty vehicle to the Moon's surface where it would fuel up with Liquid Oxygen and Liquid Hydrogen manufactured by mining and processing lunar water ice then you would be able to cut out that whole huge chunk of extra weight and propellant needed to get to the Moon and back.

Which means, you could travel to the Moon and back with much lower Earth bound mission mass, which means you can use smaller launch vehicles, which means you can get to the Moon cheaper and easier.

Not to mention, of course, that supplies of water make maintaining a mostly self-sufficient lunar base much, much easier.
I dont know about other people - and if people want to correct me, please do and I'll shut up - but I come to HN because I find interesting and RELEVANT news which are helpful to tech startups (or just techies, for anyone whos not trying to start a startup). Political, health care etc news stories are easy enough to find on digg, slashdot, reddit, google news etc. Posting them to HN only dilutes what I (and from talking to people, it seems plenty of others) feel makes HN great.
OT but first thing that I thought of (logistics were crazy):

Wow, I so don't see the point of Brands In Public. Is it for companies who don't have their own web site? Because otherwise, why would you want to reply on some third party web site, rather than on your own?
The link I provided above covers this and suggests that the foundry that created Arial didn't want to be a blatant pirate, so instead did just enough to pretend they weren't ripping off Helvetica.

"What is really strange about Arial is that it appears that Monotype was uncomfortable about doing a direct copy of Helvetica. They could very easily have done that and gotten away with it. Many type manufacturers in the past have done knock-offs of Helvetica that were indistinguishable or nearly so. [...] It’s quite possible that most of the “Helvetica” seen in the ’70s was actually not Helvetica.

Now, Monotype was a respected type foundry with a glorious past and perhaps the idea of being associated with these “pirates” was unacceptable. So, instead, they found a loophole and devised an “original” design that just happens to share exactly the same proportions and weight as another typeface.

This, to my mind, is almost worse than an outright copy. A copy, it could be said, pays homage (if not license fees) to the original by its very existence. Arial, on the other hand, pretends to be different. It says, in effect “I’m not Helvetica. I don’t even look like Helvetica!”, but gladly steps into the same shoes. In fact, it has no other role."

To be honest, I don't use Digg, Reddit or any other main stream social news sites and I won't due to several factors so don't tell me to go there. Also when some people like a story enough to vote for it this story must make sense to some "hackers" too.

I rather get tired of the hard core programming langauge stuff that's better suited for

Still, I just ignore it and don't tell others to shut up. I don't know why YOU feel entitled to me to shut up.

Btw.: Where I live hackers are the most political people around. I just say Pirate Party so I don't understand why hackers are not even allowed to discuss business and tech policies here.

If they're smart, the fact that precisely nothing would make Seth's day more than being sued by a large corporation trying to stamp down on the little guy trying to expose their horrible business practices.

Seth can't get his new business venture onto the front page of the NYT by himself, after all -- he needs your legal department to make that happen. The rest of the Fortune 500 will promptly DDOS his order takers with their credit card numbers when that gets published. He'll also collect tens of thousands of links, many of them from authority sites such as TechCrunch, Slashdot, Consumerist, the newspapers which take direction from the NYT, etc etc, and as a result rank much better for other brands than he had previously.

If they're stupid, hopefully they're not so stupid that they'll ignore the lawyers who will say there is not even a scintilla of a case.

[Edit: Its not letting me respond because the site is worried I'm flaming you, which is totally not my intent.

In sum, litigation is a last-resort dispute resolution mechanism which you use to achieve business goals. Litigation here will not achieve business goals. On a totally separate level, which is academically interesting but only that, BigCo would be unlikely to prevail with a claim of trademark infringement.

There is no danger of confusion between Ford and Ford In Public -- it says "unofficial", prominently. There is no cognizable commercial damage -- Seth is not trying to sell cars. If you were a particularly bad trademark lawyer, you might argue that someone saying bad things about your brand causes you damage, but that cuts against a finding of trademark infringement, because it tends to demonstrate that the mark is being used, take your pick, transformatively, for identification ("nominative use"), and for purposes of commentary.

But, again, first rule of law for programmers: law is not program code, and litigation is not executing an algorithm. It is a negotiating tactic.]
You are, of course, entitled to your opinion.

Ignoring my comment on the healthcare post (which I only did because you submitted a bunch of them in a reasonably short space of time and the HN gimmick was too good to pass up), I replied to your comment to tell you why I down voted it. I wasn't the first person to post and clearly others down voted you too.

A lot of hackers care about healthcare and politics - even I do. My point was that there are a lot of other sources where these things are easy to find and they are, in my opinion, better suited to discussions on those topics for that reason. HN, from the vast majority of submissions and votes, is very tech startup oriented. A lot of people I talk to come here for that reason. From looking at comments and submissions, it seems most people do. Posting other things, like healthcare, though it may be interesting or useful to people, isn't very useful here because a) it makes the articles that most people come here for (from what I can see) harder to find (signal to noise etc) and b) its trivial to find these discussions elsewhere, so removing them from HN doesn't mean anyone loses out.

You are free to disagree; I just wanted to explain my views to you.
It's offtopic, but I really dislike it when people don't start their sentences with a capital. It makes the text harder to read: a period isn't enough to easily distinguish ends and starts of sentences. I also, I immediately associate you with other people that write in this way (or worse) and believe me: that is not a good thing.

Joel does not mention that Netscape code was so bad that it cost them serious credibility and customers. As a Netscape user back in the day, I did not care whether Netscape used unittests or duct tape, but I switched from Netscape to Internet Explorer because Netscape was so buggy it was painful.

Over a few years Netscape code became so unmaintainable they had to start from scratch, which cost them years. Joel wrote in another famous article that this was a major mistake. However, if the code is a giant "pragmatic" mess with no architecture and no unittests, it becomes extremely hard and dangerous to refactor.

IE also got a lot of mindshare among developers because it actually tried to implement some standards like CSS, which Netscape completely disregarded. Netscapes "pragmatic" alternative to CSS, <spacer>, <layer> and so on luckily died together with Netscape.

Many developers started making IE-only pages because it was almost impossible to get anything to work in Netscape 4. IE6 is pretty unpopular among developers today, but this is nothing compared to how the Netscape 4 generation was reviled back in the day by anyone having to develop for it.

> Remember, before you freak out, that Zawinski was at Netscape when they were changing the world. They thought that they only had a few months before someone else came along and ate their lunch

Also remember that they lost it all, and someone did eat their lunch. So maybe the their strategy should be reexamined?

I would argue that he does point out that OO is good for certain types of applications, specifically GUI applications. I do agree with you that the application paradigm is often overly touted as the epitome of good design, but that doesn't change the fact that the original design ideas behind Unix were good ones. On the other hand, I would also argue that modern Unix software (at least in the Linux world) rarely follows that paradigm. Most desktop applications in Linux follow precisely the same methodology (and inherit its flaws) as Windows applications. They are often big, bloated, and slow.

It's not illegal to talk about a trademark or collect information about it, and present that. A newspaper article talking about a bunch of negative blogposts and tweets about a brand is not infringement, and Squidoo isn't much different.

It's illegal to try to pass yourself off as someone affiliated with or endorsed by someone when that's not the case by using their trademark. The five instances of the word "unofficial" all displayed prominently above the fold on the Squidoo pages should take care of that.

Has anyone tested any of these? I'll show you mine if you show me yours -- A/B tests, that is.

Off the top of my head: blue links beat the stuffing out of "designer friendly" links back on my old site. I'd be astonished if I still had the numbers anywhere, since I don't remember blogging about it and it was over two years ago.

I don't have an A/B test to show you this, but trust two years of look at CrazyEgg: it is absolutely, positively, undeniably true that user engagement is centered above the fold. If your call to action isn't already above the fold, put it there, watch as you get extra free conversions. (Incidentally, I put a couple of them through the copy on my home page, on the theory "Why make people scroll back up if they've read to the bottom?" Every time I add a button, the total conversion rate increases.)

Keep an open mind about God - beliefs will only block God out, or construe God in some pre-defined way. How does one keep an open mind? By not closing it.

To me, "God chooses your and its reality through you" is a better maxim to live by than "I create and choose the whole of my reality." Same thing actually, but in the latter it would be God saying the statement, rather than a person, or else a person very close to God.

"It is all futile" said Kind Solomon.

I am limited to choosing my reality to the extent that I can choose my dreams, which is basically impossible (unless lucid dreaming), but it is possible to choose the way one reacts to life events.

I got pulled up short by that ending too.

Most of the piece seems to be about the benefits of keeping it simple and doing the obvious thing that will work rather than outsmarting yourself. All well and good advice, easily applicable by anyone with the confidence to face down blowhards that would rather things feed their leet-programmer ego than actually meet a customer's need.

But then it goes into not writing tests and doing complicated bit-munging to save a bit of time or space (both of which you think would be the opposite of the previous advice of keep it simple and accept your own human failings) and which is stuff that you can only get away with if you are both talented and lucky.

If he dropped the last paragraph and the bit about not writing unit tests (which, the theory goes, will save you time assuming, again, that you're not a lucky genius) then this would hold together somewhat coherently.

Is Netscape really that good of an example for Duct Tape Programmers at work?
Granted, they got a killer application out that was succesful for quite some time but considering the following events, that is, Netscape figuring the codebase got so bad that a complete rewrite was in order - isn't it rather an example for duct tape-programming doing more harm than good?
Or am I missing something?

EDIT:
The fact that a complete rewrite is a big mistake, is another story, of course...
This is fake, but better than the last one.
