> it's not about having net energy gain ...

That's not what the NASA documents say, the documents that describe the project:

http://www.nasa.gov/directorates/spacetech/niac/2012_phaseII...

Quote: "an in-depth analysis of the rocket design and spacecraft integration as well as mission architectures enabled by the FDR need to be performed. Fulfilling these three elements form the major tasks to be completed in the proposed Phase II study. A subscale, laboratory liner compression test facility will be assembled with sufficient liner kinetic energy (~ 0.5 MJ) to reach fusion breakeven conditions." {emphasis added]

Without a net energy gain, the project would be better off using an ion thruster, which has the advantage of already existing and being quite efficient (but with a power gain < 1).
I have never use git-cola, so I can't compare, but for an overview of fugitive's features, you should probably look into the Vimcasts on that subject. There's overall five videos, this one is the first:

Why not, if you would get reputation points for it? The idea is to review the papers which you want to read anyways, or perhaps you have already read them and you want to express your feelings about these papers, hopefully in a way useful to other viewers of the paper. Nobody tells you to do it, so you do it by heart, this surely would increase reviews quality.
Wouldn't credit cards have this same problem? It seems like most online purchases are already instant-financed through credit cards, though credit approval is done in advance. Credit cards are unsecured and the whole system is largely based on the probability of the cardholder defaulting given their payment history. I don't see how this is different.
I have been working in the past few months with angular and have nothing but good things to say other than complaints about the docs and the complexity of directives/transclusion. He doesn't mention it but the coolest thing for me so far is the transparent use of promises in the templates. The unit testing support with testacular/karma is good as well, but I'm not sold on the e2e testing with angular-mocks, would like to hear more on this subject.
Since when are B-Trees ill-suited to SSDs? The big idea behind B-Trees is to store pages of keys, and SSDs still operate on pages.

The key feature of B+Trees is that they are optimized to allow sequential scans through the index - I suppose SSDs don't "need" the sequential scan property, but it doesn't hurt, and pragmatically would still reduce the number of disk reads required to perform a scan of the index.

Bitcoin is, at most, a payment service similar to Paypal. It is not a true currency nor will it ever be one. All anyone cares about is how it relates to the USD.

All government backed currencies at least start on the gold standard. After sufficient time and economic development, some countries (like the US) can move off the gold standard and lend and borrow on reputation alone.

Bitcoin was started by people who do not appear to exist, the "money" was printed by a select group of early adopters who still control vast portions of its economy, and with nobody to regulate or monitor the exchanges, the recent inflation can all be some part of manipulative collusion.

WoW Gold and Team Fortress 2 Apple Earbuds seem to have a more stable and trustworthy currency than Bitcoin.

IMO, it's just a formulaic way of naming a company that sends a predictable message.

In the 90s, dotcom meant internet startup. 'noun'dotcom told people it's an internet startup to do with noun. verbly or nounify tell people this is a post bust, Web 2.0-ish company to do with noun/verb.

'x'soft, 'y'systems, 'q'solutions... There are lots of ways this is done. Once a convention is established, it's just an easy way of naming a company that projects more or less the right signal and getting on with things.

"kinetic energy" means nothing alone, thrust and specific impulse are better metrics to look at. Doing a lot better than ion thrusters at either without being too much worse in the other and energy efficiency would be interesting.

However, the article quotes an exhaust velocity of 30km/s (or ISP of 3000s), and using 200kW doesn't leave much room to beat http://en.wikipedia.org/wiki/HiPEP on thrust without counting on net energy gain. The linked slides also claim net energy gain.

Ion drives are highly efficient, but have ridiculously low thrust. Which doesn't help at all when you are trying to reach some point quickly.

If you can construct an ion drive with enough thrust to match this proposed fusion drive (or even a NERVA: http://en.wikipedia.org/wiki/Nuclear_thermal_rocket), talk to NASA, I am sure they will be interested in buying several from you.

Me: Neuroscience PhD at Columbia w/ some a technical background but not a coder.I'm working on going up against academic publishing right now. I have a YC application that is currently being reviewed and I'm in need of a technical cofounder.

Project: Very briefly, I'm working on collecting raw data (positive AND negative), indexing it, and making relationships between datasets. For example, my neuroscience study has relationships to cancer biology, so the data presented to the user would include results from both.

Re: Publishing, I'm going to provide raw data to scientists and create a venue for them to "blog" about these datasets. I think science needs to move incrementally (at internet speed) and get away from taking 3 years to produce a study and publishing a big paper of only positive data. Also, I'd like for the "peer review" portion to be more transparent, so that we can avoid the insane bias that goes into peer review.

Goal 2: Create "big data" by combining small academic science results into a big ass database. Meta data could be the new preliminary data for academic grants.

So yeah, if anyone is interested in playing with this, let me know.

I think that could be a successful community, you just have the same problem as any social community, finding users. Especially ones of interest that are open to publishing anonymously and listening to anonymous reviewers.

The real tragedy is the general reference, social science, and humanities journal diaspora where the usage and demand has skyrocketed with the increased access online resources allow to lay researchers. The science journal communities are way ahead in self-sufficiency in adapting, and are increasingly open to the corrupt state of publishing and alternate community publishing platforms.
From the article:

> They use a number of different criteria to identify fake Twitter accounts, including:

> The account is following less than 50 people and has less than one follower

> More than 30% of all tweets use spam phrases, such as “diet,” “make money,” and “work from home”

> The account is more than two months old and still has a default profile image

[/quote]

I don't know exactly how these things were weighted to decide that an account is fake... but apart from the second point, it sounds like "Fake" account could be more like "I signed up just to follow this guy and then forgot about it" account.

How about not revert to a "default"? Just serve a redirect to the HTTP version if a HTTPS is not available for that vhost.

>> Obviously anything less than break-even is not worth having

> No. Not at all.

Yes -- if the fusion reactor didn't achieve break-even, the designers would be better off using an ion thruster. Also, the NASA documents that describe the project assume that break-even must be achieved:

http://www.nasa.gov/directorates/spacetech/niac/2012_phaseII...

Quote: "an in-depth analysis of the rocket design and spacecraft integration as well as mission architectures enabled by the FDR need to be performed. Fulfilling these three elements form the major tasks to be completed in the proposed Phase II study. A subscale, laboratory liner compression test facility will be assembled with sufficient liner kinetic energy (~ 0.5 MJ) to reach fusion breakeven conditions."

They are talking about doing away with the present lines of fusion research, which haven't achieved break-even, and using a different method. But they don't suggest that this, or some variation, might be used for conventional power generation.

> Although it would be desirable, it's not required to make it a net-positive reaction

Yes, it is -- that is required. Were this not true, the designers would be better off using an ion thruster, which already exists and is quite efficient.

> As the article mentioned, you can power this rocket with an ISS worth of solar panels ...

Yes, that's in the description, but the power available (200KW near earth, 100KW near Mars) is not enough to propel the relatively heavy craft to the mission profile (i.e. 30 days to Mars) without some other source of energy, like from a net fusion power gain > 1.
> The point is not that gold and silver were stable, but that they have been more stable and have kept more value than fiat/debt-based currencies.

Which is exactly half true. They have been less stable (more volatile) than major fiat currencies, but kept more value over the long term.

"Less stable" makes them worse as currency. "Kept more value" makes them potentially better as long term investments.
I don't think one inequality justifies another.

I do think that to a privileged person, any move toward equality feels like inequality, because what they notice is things getting worse for them.

I also think that people emerging from oppression are liable to cross the line of exact equity from time to time. An as long as the swings are small, I'm ok with that. Specifically, as a guy, I'm saying I don't mind brushing off something that might be a bit of anti-guy sexism. Because that one small nettle-sting is nothing in proportion to the benefits I've received, or to the scope of the historical wrong that we are righting.

I don't know enough about Lulu to have an opinion on it. And for the record, I'm opposed to hiring practices that advantage women. I am strongly for, though, active practices to eliminate the disadvantage that women face.
>putting fiber into a village with ~300 residents , half of whom are over 65

Actually, that's probably a no brainer as well. A village of 300 can't cost _that_ much, and improving network connectivity to a small town means that town becomes more attractive to the people who will be inheriting and buying the homes once the 65-year olds shuffle off this mortal coil.

Also, don't knock seniors. My 77-year old father blogs daily and my 71-year old mother spends a lot of her time playing with her new iPad mini. They live in a small town with new fiber.

Ask HN: How do I choose the right domain registrar?
I'm trying to secure a somewhat decent .com domain so I have a space to put projects or even a blog so I can find some work. Also to have a mail address that does sound a bit more professional.

So far I've looked trough the usual articles (blogs, lifehacker stuff, e.g.) which advise against GoDaddy and recommend sites like Hover, Namecheap, Name.com and Gandi.

They all seem to offer nearly the same stuff for nearly the same prices. I'm really not sure who to take or if it even matters.

Not all of them offer cheap mailboxes. I really like to have name@domain.com without too much hazzle or beeing bound to gmail(which costs money anyway if you want to use your own domain if I understand correctly?!).

Gandi comes with a free mailbox which I guess is great. Namecheap asks for an additional tiny fee. Name.com doesn't host mail. Hover asks for another $20 which is a bit steep.

I'm living in Europe, does it matter whether I use an US-based registrar? Does it if my site would be used for a business?

I'm beeing overwhelmed by choices.
Show HN: Rappad - Write better lyrics
Maybe you didn't mean to use that example, but I think your point is kind of defeated if you say when women are simply being conservative or cautious and append that to a very non-cautious act. Getting sloshed is not the cautious way to go about something whether you are male or female. Your chance of being a victim of a crime (not just sexual crimes) goes up when you get drunk.

Before anyone jumps the gun, I'm not saying that someone raped while drunk is at fault. Only that this is a bad example of someone acting cautious at all. Caution and being protective (or the lack there of) != fault.

Picking up heavy things should be done with caution. Even good form isn't enough if you haven't done it in a while or suffer from (hidden) conditions that could make it problematic. Start by picking up things that are not heavy and make sure your back can take it before moving on to heavier things.

Inflation is a tax on held currency. You may think a tax on wealth is good or bad, but from a policy position I don't see a compelling reason to argue about it in any other terms.

This means that inflation encourages people to hold their wealth in assets other than currency.

Considering that wealth aggregates at the top, the effect of inflation is greatest on the wealthiest.

This also means that if you have $100 worth of assets held in a currency that is expected to depreciate and $100 worth of assets in a currency that is expected to appreciate, then you will spend the former rather than the latter.

Hence the argument that deflationary currencies are worse than inflationary currencies as a unit of exchange.
No, you're the troll because you don't appear to know any feminists, or what feminists read.

Jezebel and Slate's XX Factor are definitely prominent within the feminist blogosphere (if there is such a thing).

You're also trolling by comparing a startup to the clusterfuck that was the Pycon incident. They are just simply not similar events. There have been creepy dating or hookup apps which have come up on Hacker News in the past. And this conversation (your trolling aside) very much resembled them.

So, please, tell us more about what you think feminists should be doing in detail. What should I as a feminist (someone who believes in equality more generally) have done?

It is unfortunately a necessary evil of most enterprise sales situations. My company started out by providing clear, public, easy to understand pricing on our website. We quickly discovered that many large companies expect to get large discounts off of "list" price, and even if your pricing is on par with, or less than your competitors, you end up talking to people who say things like "I won't sign anything if I don't get at least 20% off list price". It's a weird weird world. Companies like Oracle who routinely discount 80+% off of "list" set these expectations in the market.

I'm not 100% behind the Mendeley hate right now, but they're against all odds. While everything I've heard from the team so far, including on the prominent HN threads, has been reassuring and positive, it's still just words.

People are making predictions about the future right now, and no words will be able to sway public opinion. Only action, and time. It seems Mendeley (or, as of now, Elsevier) are betting on the latter, because there has been no action, only PR.

> "Fiat" currency is usually backed by the gold standard until such a point as the reputation of the state has matured to the point where borrowers can trust the state.

That's not really true; even immature states with poor reputations rarely have gold-backed currency these days. Some of them have currency backed by (convertible at a fixed exchange rate to) more mature fiat currencies, though.
>Instead of blindly blaming feminists (without actually understanding what most feminists actually stand for) for them being on the marketplace

Why do discussions like this always get such ridiculous strawman arguments tossed around? Nobody is blaming feminists. People are pointing out that the vocal, hateful group of internet "feminists" constantly claim they are against sexism in all forms, and thus men's rights advocacy should not exist and those people should just be feminists. But in reality, when obvious sexism like this happens, those same "feminists" do not speak out against it.
I've been impressed by how many odd cases their website editor handles. When I first started experimenting with Optimizely I got curious and tried loading maps.google.com and replacing one of the map tiles with a picture of my dog. I didn't expect it to work, but it did.

So then I made a little torture test page with all the different ways I could think of to insert content into the page dynamically, and they handled them all perfectly.

Kudos to the Optimizely team: This is some serious attention to detail.
Forgive my ignorance, but CouchDB does not run in the browser, right? So am I correct that the "mostly in the browser" statement doesn't apply to that particular data store?
> You are completely missing a point of this. It is a propulsion system, not a power generating one.

To represent an advantage over an ion thruster, it must be both. And the NASA documents that describe the project specify a fusion power gain > 1:

http://www.nasa.gov/directorates/spacetech/niac/2012_phaseII...

Quote: "an in-depth analysis of the rocket design and spacecraft integration as well as mission architectures enabled by the FDR need to be performed. Fulfilling these three elements form the major tasks to be completed in the proposed Phase II study. A subscale, laboratory liner compression test facility will be assembled with sufficient liner kinetic energy (~ 0.5 MJ) to reach fusion breakeven conditions."

The phrase "fusion breakeven conditions" means the reaction must produce more power than is requires to start it. This is a requirement to justify the project over other approaches.
