It isn't really a walled garden. It's just that pretty much everything is inside the garden and there is very little outside that that anyone would want.

Interestingly enough, the only commercial software that Linux people regularly install is it's own separate walled garden; Steam.
What do you suspect their motive is?
Let's get some data in here?
Interesting Multipath TCP talks
Re-read that comment, particularly the part about the difference between a collision attack and a preimage attack.

MD5 is (currently) vulnerable to collisions, but not to preimages. So you can find two inputs that have the same hash, but not an input that hashes to some particular value in a database.
Because bcrypt automatically generates and adds a salt every time it's invoked. Every bcrypt hash has a different salt. Hashing the same plaintext ten times will produce ten different hashes.
Just a couple of notes. The "Rizos et al. in JAMA 2012;308:1024-1033" refers to the article:

Rizos E. C., Ntzani E. E., Bika E., Kostapanos M. S., Elisaf M. S. (2012). Association between omega-3 fatty acid supplementation and risk of major cardiovascular disease events. JAMA 308, 1024–1033 10.1001/2012.jama.11374

The article can be read for free here:
http://jama.jamanetwork.com/article.aspx?articleid=1357266

The reason for using .006 is stated in the article:

"Within each assessed outcome, we adopted a level of statistical significance adjusted for multiple comparisons testing by a factor of 8 equaling the number of overall and subgroup analyses performed using the 2 measures of effect (RR and RD); thus, statistical significance was assumed at a P value threshold of .0063."

P-value adjustments are fairly common [1], but I'm not smart enough to say if it was applicable in this case.

Also, in the interest of full disclosure, it might be worth mentioning that Bill Harris is the President of OmegaQuant Analytics [2], whose stated purpose is to "advanc[e] the science and use of omega-3 fatty acids to improve health."

[2] http://www.omegaquant.com/. He also seems to have a pre-canned response, which he pastes as comments to various sites. The pre-canned response is here: http://www.omega-3centre.com/images/stories/pdfs/harris_jama...
Funny how history just keeps repeating itself ;) #IfItAintBroke
I checked the Rizos et al study (http://jama.jamanetwork.com/article.aspx?articleid=1357266) and the statistical issue is a bit subtle. They applied a multiple-hypothesis correction, to account for the fact that they were looking at multiple subgroups and endpoints. The problem is that in their data, most of the subgroups and endpoints show an effect, and these aren't being combined together. So in that paper, no one subgroup alone contains enough evidence to show an effect, but the groups put together, do.
Yeah it seems pretty crazy that they are targeting the smallest sliver of water use for restrictions. I'd think we would want to limit the restrictions on everyday citizens and focus on the farmers who are fewer in number and, I would assume, easier to control as a whole than every citizen in CA...
Because bcrypt uses a salt, so a "rainbow table for non-salted passwords" would be utterly useless.
The general premise still holds though - As long as the pre-money in a round exceeds the post-money in the prior one, the owners are worth more. The analysis is over-simplified, but it still explains the situation clearly.

As for how much is given away... I think Cloudera is a special company. Most of the unicorns are. The same strength ("We can wait on the money") that gets them to a billion is also what allows them to get away with less dilution.
What are those coefficients and how are they calculated?

I may live in the densest neighborhood of any HN participant: North Battery Park City [1] in Lower Manhattan. As an example, my son's 500 kid elementary school serves 9 buildings.

And I'm here to tell you, the future feels great. Specifically, living vertically has all sorts of wonderful aspects in terms of community (the kids can trick-or-treat without leaving the building), access to resources (my kids can ride the elevator barefoot to the waterpark out the back door in the summer) and environmentally (we live in the first LEED platinum residential building in the US).

The only problem is that it is expensive, and it doesn't need to be as expensive as it is. Building lots more residential skyscrapers, eliminating parking minimums [2], and reducing the incentive to warehouse vacant lots through land taxes or similar can all make New York City even more livable than it already is.

No, brute-force attacks are different from rainbow tables: http://en.wikipedia.org/wiki/Rainbow_table
It seems you missed the "(...) if the security was lax" part.
That's not the problem: the problem is "cancer" is not one illness, with one cause. It's a grouping term for literally thousands, and likely millions, of specific variations which result in unique cells which evade normal anti-cancer immunoresponses.

Even if you developed a vaccine which sensitized the immune system to one type of cancer, chances are the "type" would be limited to pretty much just the 1 person you tested it on.
This is seriously not true.

I've had experiences of projects I tried to get involved because I liked the software but where the maintainer had zero interest in involving any new people. It's lovely that developers scratch itches and create cool software - there isn't anything that implies those same people want to work with other new people.

I'm glad you had a good experience and maybe I was unlucky or whatever but I don't think mere interest in the software is enough, the project has to be in a state where the developers want other programmers involved (lots of projects would like some testers and documenters but nothing else and to an extent understandably).

I mean, I'm not sure why guidance towards accessible projects is a bad thing.

Edit: Oh I knew I'd get reactions. Counter-arguments?
A lot of professional software teams have a hard time adding new people. Why would any old open source project be easy to get involved with?

Edit2: I love the idea of open source, I want to get involved again in a larger project when I have time but the "no problems" guidance approach seems itself a problem. Lots of projects are even infamous for problems. There's clearly more to what project you'd be a fit for than "what you love" and just leaving that as the advice seems like a characteristic problem of open source itself.
I think maybe you missed it a bit. If attackers can spend a bunch of money to guess enough passwords to be useful in, say, weeks, then if you make it take 100 times as long, now it's years.

And using scrypt with a decent work factor isn't 100 times harder, its tens or hundreds of thousands of times harder.

Additionally, I think one of the benefits of scrypt is that it is specfically designed to deter GPU or FPGA attacks because it is memory intensive instead of just CPU.

Dawkins [EDIT: remove adjective] believes in kin selection, based on results of inclusive fitness theory, which makes predictions about fitness when interacting organisms are related. (e.g. ant workers share 3/4 of their genes, and ants are remarkably social.) Wilson et al. contend that inclusive fitness theory is a bit of a distraction, since it only applies in rare cases, and in those cases it's just a specialization of direct fitness, which can be calculated without respect to relatedness. Later in the supplement they build a model which has the features discussed by kin selection without relying on relatedness.

How is this not simple vandalism? Throw the people responsible in jail.

If they are outside the country, freeze their american bank accounts <i>and</i> the bank accounts of any business that advertises with these injected ads. Precedent: we already have laws that, for better or worse, require hardware stores to perform age checks when someone buy spray paint.

This isn't primarily a software problem. This is a problem because nobody is enforcing vandalism laws which encourages the adoption of "vandalism as a business model".
If 100 biologists sign a petition saying your model is wrong that should be a sign that it's time to double-check some things. And here we have an economist lecturing scientists about how to properly view and use math? True, biology is on the "softer" side of the scientific spectrum but I'm not convinced economics is even on it.

"Math comes first" is a bad strategy. I'd (softly) argue that just like your probability of randomly hitting a rational number on the number line is zero, the probability of a given framework of math describing reality is also zero. You must explain why you think the math is relevant and descriptive of reality. Or you can demonstrate that your framework allows you to make better predictions than anything else. Either way you'll have to use your words.

Yes? That's about 100 years old and not part of the NYC subway. It also requires you to leave and pay again on the NYC Subway. It's a great system, and about a 12 minute walk from my apartment, but not what I meant. Not sure where you're going with this?

Anyway, I was thinking more along the lines of extending the 7 to NJ.

http://www.nj.com/news/index.ssf/2015/03/could_the_new_port_...

Enter the train at Secaucus, for example, then be able to go to Grand Central Station. Part of the hassle of mass transit is that if you need to make 3 transfers, and have to wait 10 minutes at each one, your commute gets long fast. Extending the NYC Subway in NJ would have several benefits, including reducing the slow crawl through the Lincoln tunnel, where almost 7000 busses cram in daily.

> There are botnets with hundreds of thousands of hosts in them.

Which have a wide array of other mechanisms by which to DDoS your application. If that level of force is being directed at you, you need professional DDoS mitigation assistance. The CPU time cost of your login mechanism is immaterial.

> There are proxies and NATs with hundreds or thousands of users behind them.

You do not need to throttle an IP if it is not the source of an attack. But it remains inevitable that a serious DDoS will sometimes break legitimate users, even with intelligent mitigation strategies. Welcome to the real world, it ain't pretty!

Ask HN: Is it OK to invest $$$ from a profitable biz into an unrelated startup?

My question - Is it a good idea to invest cash from a profitable business into an unrelated startup?

I currently run a consulting business and am thinking about investing part of cash I earn into a startup idea.

If the startup is unrelated - isn't this a really bad idea?

There is a discussion here talking about building a product within a consulting business which is unrelated to the business itself, they had to shut it down because of amount of friction it caused and the focus it took away from the team: http://mixergy.com/interviews/bryan-zmijewski-zurb-interview/

Here's a 2013 Facebook comment from Taleb that highlights the grudge...

Richard Dawkins, in his statement about the number of Nobels granted to Moslems, showed a total ignorance of probability. A primitive violation. You never get an idea about the mean from measuring the tail (number of Nobels per capita).

"How can genetically prescribed selfless behavior arise by natural selection, which is seemingly its antithesis?"

"This problem has vexed biologists since Darwin, who in The Origin of Species declared the paradox — in particular displayed by ants — to be the most important challenge to his theory."

"Eusociality is not a marginal phenomenon in the living world. The biomass of ants alone composes more than half that of all insects and exceeds that of all terrestrial nonhuman vertebrates combined. Humans, which can be loosely characterized as eusocial, are dominant among the land vertebrates."

Not every dead language is a result of a genocide. My question stands on it's own, and there is more to it than what you imply. Yes, the most obvious, ready examples are what you say, but not all.
School size has nothing to do with the scale of the overall system country-sized, though. A small education system can use a small number of large schools, and a large education can use a large number of small schools.
Even if those correlations hold true and have the effect you're describing (I'm far from convinced that's the case, but it's moot), it strains credulity by a mile to claim that this is some byzantine plot for "backdoor age/sex/income-discrimination". That would mean that those making decisions about open offices are 1) thinking through the complex and frankly tenuous connections that you're describing, 2) finding them credible, and 3) deciding that the collateral damage to other employees' productivity and happiness is somehow worth the weak effect this would have on furthering discrimination. There are an infinite number of ways to backdoor-discriminate on those bases that are not very noticeable, far more effective,

@teraflop - Oh, so does that just mean basically that you can, e.g. generate a bunch of MD5 hashes and some will be the same? But if you have a target you're basically SOL finding a collision for that? That would make sense if that's what it means.
But... you've got no experience with any other accelerators on which to base that opinion. Uninformed and unrepentantly incendiary is not a great combination.

I'm not saying you're wrong for feeling this way about YC. You aren't. Everyone has opinions they haven't bothered to verify with data, some of which might rub other people the right way. The trick is remembering that they're probably not worth sharing to a large audience, or stridently defending.

Even as drought continues, California gets ‘second-hand smog'
I used to play a trick on myself where I'd hold a particular hand position and meditate on a state of mind, one intended to clear my mind and get centered, the other to get me amped up to go do some work. (I worked in construction at the time) It worked amazingly well, and I spent several weeks / months feeling no other emotions. I'd feel the state slipping, and just hold the hand position and the state would come back. Only reason I stopped was that the emotional monotony got old after awhile.

I have no trouble believing that fish oil as a mood stabilizer can work fantastically, and yet have no physiological effect whatsoever.
