I believe they are using a non-standard crossover operator in this implementation. A standard crossover operator will generate some permutation of the genes of the two parents: either you inherit the gene from your mother or your father. This implementation creates a new gene that is a weighted average of the genes of the two parents. This will probably cause rapid convergence of the gene pool, which may or may not be intended. Changing Math.random() to Math.round(Math.random()) in crossVars would change this to the standard crossover operator. I'd be interested to see how this affects performance.

nearly two in five deaths in traffic accidents are caused by speeding in Germany

I challenge you to demonstrate that it's speeding in itself that led to the accidents. I might believe that it's speeding in conjunction with other asinine behavior, e.g., you change lanes unexpectedly, and since you're going really fast, neither driver has a chance to react. But in such cases, the speed isn't root cause, it's an aggravating factor.

Why not go for the root cause, rather than concentrating almost exclusively on the aggravating factor?

Using Social Tools to Kill the Recession
If you missed the 2nd annual Settimana del Baratto last week, then you may still be in luck for a good barter. It seems that people have finally decided not to participate in the recession. I knew it wouldn’t take Americans and other countries long to innovate their way out of economic woes.
Why should I demonstrate that? You are the one making assertions without evidence.
it saddens me that a congressman can say something like that and not be driven out of town for abusing the 1st amendment.

How can you make laws, when you don't know that the first amendment guarantees the freedom of the press.

Christopher Reeve delivering the line "Truth, Justice and the American Way" as Super Man is one of the defining memories of my childhood.

I worry that once Americans become cynical and scared enough to stop aspiring to that line, it will then be a short trip to a fascist or pseudo-fascist state.

Naive? Perhaps, but if you don't have high and lofty ideals, then what is to be the counter weight to doing everything and anything in the name of safety?

Interesting comparison of iPhone vs. Android markets
He's making the (correct) assumption that the speculative stock market where active investors expect to make their money is a zero-sum game. For there to be winners in "buy low, sell high" there have to be an equal amount of losers.

So, if there are going to be winners, there have to be an equal amount of losers. It's difficult to siphon money off of someone passively invested in an index fund, so the active investors are competing against themselves.

Because active investment has a much higher cost than passive, as a group they will be significantly worse off compared to passive investors. This is so self-evident as to be not even worth betting against.

Note that this isn't to say that there won't be big active winners individually. But in a chess tournament, if the top players use strategy A that wins 90% of the time, and others use strategy B that wins 51% of the time, that guarantees the existence of some other strategy that performs below average.

The stock market isn't necessarily a zero-sum game like chess because companies pay dividends, but that's rare and small enough to be insignificant compared to the amount of money gained and lost through speculation.

Perhaps as indicators of the business environment. For example, perhaps your model would indicate that successful startups from the last few years would include the word "social" in them. I doubt the implication goes the other way.
Have you evaluated your model on the standard evaluation sets, and if so, how does it compare to current state of the art?
I would immagine that almost every non-trivial robot you find in a research lab today includes a Kalman filter somewhere.

I know the balancer I worked on (https://collab.cc.gatech.edu/humanoids/node/1241) certainly does, although from that project I can also tell you that most Kalman filter implementations are probably incorrect. It's fairly easy to implement a filter which behaves quite well but does not actually behave like a Kalman filter.
Because very few are capable of creating it. It's easy to find fault, but much more difficult to create a solution. That's why nothing is changing. No one wants the responsibility of doing it.

Should the government ever be allowed to have secrets? To what level should government correspondence be public? Some situations (e.g. the Manhattan Project) necessitate secrecy. What exactly is wrong with that, at least in some situations, and why are we so willing to assume WikiLeaks/Assange knows what should (or shouldn't) be leaked?

Just trying to understand as it appears the overall thought process here is, "leak everything - the end."
The legal, societal, and political definition of Terrorism was changed around the same time as the patriot act was enacted. It now is used as a politically charged buzzword to assign to any group who practices guerilla warfare and the united states government does not like. Historically we tend to call them "Freedom Fighters" when we agree with them. Publicizing the secret actions of the government meets the above definition to said governments requirement.

Actually, no. What he says is, that one could qualify Wikileaks as a terrorist organization, if one were to take the definition of 'terrorist' from the Immigration and Nationality Act. Note that under this act various activities fall under 'terrorism', none of which requires 'causing fear'. For example under this act, if you highjack a plane, be it for money or to get a couple of prisoners released, you're still a terrorist, even if you don't want to instill any fear.

So his point is that to put anyone on the terrorist watch list, that person needs to be qualified as a terrorist, obviously. But the term 'terrorist' doesn't have a fixed, unambiguous meaning; it can mean many things to many people in different context (ergo that phrase 'one man's terrorist is another man's freedom fighter'). So if one were to use the definition from the INA, which he is arguing is just a good a definition as any others, Wikileaks (or its members/representatives) would qualify and as such be put on the watch list, which would then cause a whole bunch of other things.

Note also that this definition of terrorism far outdates the post-9/11 terrorism scare, so it can't be blamed out overzealous Homeland Security stuff or anything.

So nice try, but no cigar.

I think the requirement to reward managers for having small (but effective) teams is particularly insightful. We know about Fred Brooks and the Mythical Man Month, and we explain to the managers of our projects that 9 women can't produce a baby in 1 month until we are blue in the face, but they never seem to 'get it'. Surely one of the core problems with them 'getting it', is that even if they really did 'get it', in most organizations the incentive is towards larger groups, not smaller groups.

Economists and psychologists have been telling us that incentives matter for a long time now, perhaps it is time to apply that to an organization structure in a genuinely scientific way.

Oh, they're bad at communication, all right, and not just because of some spelling error. Look at the description of their flagship product:

http://www.starling-software.com/en/qam.html

What does it do? Who would use it? For what? I have absolutely no idea, and I don't think I'm the absolute dimmest light in the Christmas tree. They use totally general words like "component" without explaining what they mean to them in this context. A component could be an object which implements a specific API, or a set of files with version information attached, or whatever. I don't feel like I know anything about QAM after reading that page. And I don't feel like continuing to learn about it, either.

Anyway, I do realize that Starling had nothing to do with submitting this to HN, but I still think they deserve some flameage for the general sense smugness and self-congratulation which one gets from their website, especially since those don't seem be backed up by any world-beating performance.

As a developer you are bounded by how much you can develop in a fixed amount of time, how much someone will pay you for it, and how many customers you have. If you could, would you not get payed more for your work? If you are working for someone, as I am, then you essentially have only one customer and they are paying you a fixed amount (+ some bonuses and raises). Or you could be like the author of minecraft, so you could be racking in hundreds of thousands a month.

Now if you say you have found a way to beat the market through research, technical or fundamental analysis, your limit would be unbounded (theoretically). Your charts looks good and are very impressive, but it is only 2 years and you would not be showing them if they didn't do well. So for all I know you are just one of the random lucky ones that beat the market. Now if you had a way to consistenlty get 10% (and maybe you did!), in a decade or so you could be another Donald Trump. You need to convince others that you can do it and then soon you will start getting large investments.

> What defines there success is that they stay in the black. Hence, they are able to time the market.

If they can time the market, are they fully invested in it. Would they sell their house and get everyone they know to do the same so they can pour that into the market, then re-invest and eventually rule the world? Another way to ask the question is why haven't the big investment banks figured out the strategy, and as a result, diluted the strategy by now?

Also what about the ones that don't stay in the black. Will they tell you, would you know how many have tried and failed? That is the true criteria. You would have to have a large group of traders commited to making money in the market. Then they all try for a fixed amount of time and in the end you see how they perform as a group. Now, essentially, you are just pickding the ones that performed in the black and using that as an argument that invididual trading can be a 100% profitable business.
On 9/11/2001 it meant something to be a terrorist. However, these days it means nothing. Everything the government doesn't like is a potential terror threat, and every person acting against it could be a terrorist.

There's a big difference between terrorist, activist and military combatant.

The reason you do not want to outsource is not because the other does not care. DocStoc had its first version offshore outsourced and they quickly rebuilt it once they got traction.

The reason why outsourcing your startup product usually fails is Cost. You have to go through several versions of your application to reach product-market-fit. I think the Advaark team went through 9 months of iteration before launching. Kissmetrics went through a similar process. Startups continuously pivot, and most people do not have the money to fund this discovery process.
We're now tracking traffic to all the cams, so that's a lot easier now than it used to be, as for the monitoring, that's when we enforce the clean site policy, in that case the 'dirty' cams don't live long enough to garner substantial traffic. A minute or so at most before they're gone.
I've messed around a little bit with it, but I know some of my quant friends do it more seriously. There's definitely ways of making money of betfair, you even occasionally have arbitrage opportunities across the different markets on betfair.

I think the fundamentals are close enough that it's a useful place to learn. You're not going to be able to take a method that works on Betfair and apply it to a real market, but a lot of the statistical mining/predictions techniques you can use of betfair are exactly the same as those used in real markets.
The problem here is the definition of 'Spam'. The things that are showing up on these pages aren't really Spam. They're something that one of their friends has allowed to be posted, probably because they get (or expect to get) some benefit from it.

'is friends with' posts.

'likes X product' posts.

'is a fan of' posts.

Could this instead be turned into a challenge response system.

mailhide+ would give you a disposable email, the person sending would use that, get back a captcha link, solve the captcha and your email is forwarded on. Optionally the sender is then whitelisted for sending to your address, further options would reply with your direct email address once the challenge had been completed.

This would mean that you'd have an email address to give people when asked for an email address (rather than a website).
