I'm genuinely curious if anyone has studied the differences in the sexes when it comes to math.

Why is it no woman has won the fields medal? Why do many talented women stop their academic career at the bachelor and masters level when it comes to mathematics?

I think you would of been able to say that sexism in academia was a reason in the past, but I just don't think that really flies anymore.

Is it possible the genuinely is a difference between mathematical ability between men and women or do people this this is purely cultural?
General relativity passes a large scale test
Most "normal" athletes simply live a lifestyle unbeknownst to them. It's just "natural" to be that way. Any bodybuilder has had to actively shape their appearance, which is the ultimate test for anyone actively wishing to modify their fitness or appearance.
Daylight Savings Time: Bad for All, but Worse for Some
I don't know. How "complete" do you need a one-off solution like this?

I'd have no qualms sending my friends or a work group to this site to solve a scheduling problem in a hurry.
Ask HN: Why is this clojure example so slow?
Hello HN, specifically those that have some clojure experience.

I've been playing around with clojure some more, specifically this tutorial:

http://github.com/swannodette/enlive-tutorial

I have a pretty fast box to play around with (I guess most of us do), but the tutorials run extremely slow, scraping HN takes a bit of time, I understand that, but then to list the items should be really fast.

Instead it looks like the data is coming out of a 9600 baud modem.

Is there any specific reason for this?
Of course, they own canon.com, and http://canon will generally redirect there. Then they set up their own nameserver to simply do things like redirect blah.blah.canon.com to blah.blah.canon.

Then you find yourself asking what the point of all this is again because DNS is already hierarchical and once you own canon.com you already own an effectively-infinite series of subdomains, so Canon is spending $185,000 + ongoing maintenance so they can trim ".com" off and incur first-mover expenses as they encounter those problems you mention and that seems hardly worth it. But hey, who am I to argue?
Haha you should email me I think we'd be friends
A Media Company Mating with an E-Commerce Company
I appreciate how paying for donors (even in the form of a charitable donation) can be seen as a slippery slope, but I really only see two options - 1) Allow payment, or 2) Automatic Opt-in system for everyone to be a donor.

Since the second is perhaps less politically palatable, and (as the article notes) in the US there are already precedents for blood and sperm, I wish this legal action every success.
It's not because the iPhone made it the default that they pioneered it. I believe the OpenMoko had this interface, most windows mobile phones had this style, Android look like this since the beginning.
DNS is a wonderful protocol for the most part. The problems you think you have with it are almost certainly problems with the centrally-run canonical DNS, but nothing stops you from not using it. You can use whatever DNS you like, set up a parallel internet if you like. Of course, nobody can find you, but that's the price of nonconformity. However, the mere fact that this is possible will always tend to rein in the central repository, because if they get bad enough, we can leave. It might hurt, but we can leave.
why the f would anyone want to look like a bodybuilder? I care about health, not cheesy looks
For all of you saying "well, other people will also have done the same thing, so it won't matter" or "if you don't understand and forgive me for stupid stuff I did when I was 12, then you're not worth having as a boss", etc.

This is rationalizing. The problem is that people are only too willing to NOT forgive you for stupid stuff they did themselves, only didn't get caught at it. So yes, perhaps there will be lots of "cool" places where everybody has a colorful public past, but you can better damn be certain that there will be lots of places where people didn't leave their dirty laundry around on the internet.

I'm not saying I like it. I'm saying that expecting other people to cut you some slack because basically, well, we're all screwed up at one time or another -- that's whacked. People have known that we're all screwed up for centuries. Hasn't changed the nature of mankind at all. I seriously doubt the internet is going to change that.
I'm actually amazed at how quickly Chrome gobbled up 5% of the market.
The "obvious evidence to the contrary" was the math gender gap, which was very real at the time. If you actually read the story, it's quite clear that Feynman is telling the story at his own expense (showing how wrong he had been about girls + math). There's no question he was sexist, but see _debug_ and blackguardx's tandem quote to see that he regarded them as equals mentally: http://news.ycombinator.com/item?id=1197382
Someone registered that domain name just to host a pirated copy of a book?

(Mind, it's one of my favorite books).
All this highlights is their complacency up until now. Competition should never have been the thing that stirred them into making a browser that wasn't dire, it should have been a matter of course.

Imagine if they had to fight for operating system dominance.
What was the quality of the women who responded favorably to this line? :P

I think it's also worthy to note that the origin makes a huge difference. If you e.g. have an underwear model trying that line on a woman, it will no doubt succeed more often than if a stereotypical truck driver delivered it in exactly the same way.
I'm happy for people to benefit online in proportion to the value they provide to others. Post a thoughtful comment, write a review, link previously disparate ideas? Sure, put in an affiliate link. Hijack the top comment on a thread with just an Amazon link? Not so much.

At least you were up front about it, I'll give you that. :)
Hey ryszard99 - drop me an email jacobaldridge at google's email service. I'm a Brisbane business coach so happy to offer any thoughts about your business plan, and I have some (some) connections into funding.

General rule is that it's best to look for investors when you don't need them, but for great ideas with a realistic plan that's not hard and fast.
Why are you "fine" with US covert/clandestine operations as long as they're done "according to process"?

I contend our foolish interference overseas lead directly to the blowback of 9/11 and current tensions with Iran, for starters. Nothing good has come to US citizens from the nonsense the intelligence community gets up to. It should be cut down to a twentieth the size ($25 billion or whatever it is these days is ridiculous).
On the other hand I keep hearing that breakfast is the most important meal of the day and that instead you should eat very light diner. If key to proper fitness (and body building) according to the original article is proper nutrition, why would you skip the most important meal? Of course, breakfast should be healthy and not a load of pancakes on top of waffles on top of sausages that is considered breakfast in many diners.
Yeah, but it is a resume of sorts, its what the site is about. Still cracked me up, up you go :)
Aw that's cute. Are you going to make-out?
Pornography is not some innocent indulgence. It is dangerous and harmful. It cannot ever produce a net good upon its user. It's not like playing a sport or game where effects incidental of the enjoyment are beneficial to the participants. Pornography is always bad.

And once again, we go from here to there with nothing in between. A good argument starts with a set of facts, and then gradually introduces more facts and commentary until the conclusion is the natural outcome. Your arguments start and end at the same place, assuming facts that you never introduced and that, arguably, aren't even facts.

My opinions are just as good as anyone else's. You are free to do research and substantiate or dissubstantiate them. I'm not interested in finding and providing that research in this context as noted elsewhere in this thread.

I don't need to "do research and substantiate or 'dissubstatiate' them". Your opinion does not matter to me. You said something, I think you're wrong. I am going to continue advocating the awesomeness of porn, and there's nothing you can do about it.

It seems like most of the educated world agrees with me, so right or wrong, I probably win.

And finally, I disagree that your opinions are any good. A good opinion is based on provable facts and personal experience. Your opinions are based on neither!

(My opinion is better, because I have personal experience with porn. You speak in absolutes, but are clearly wrong, because I look at porn and this action hasn't adversely affected my life in any way. If your argument was correct, my life would currently be ruined.)
I think that "math is what it is" is a false statement, at least in the way you intended it. The way math is represented is not at all inherent to mathematical structure (i.e. left to right, the characters you use, etc.) and I'm sure many procedures we use to solve math equations could be done in different ways (long division vs. short division, for example).

It is possible that the way we represent math and the way we solve mathematical problems is somehow inherently more difficult for females, and that a different system might better.

But I have no idea what system that would be, and practically I don't think it's worth it.
Agreed.

For the record, it is very hard to contract HIV from vaginal sex. (< 1/10000 per-instance chance)
I did read the whole article, but did not get the impression that it was meant to be a joke at his expense. That's just not supported by the text. The most he's willing to say is that "if it is done in the right way, you may be able to get something out of it [the female mind]." Hardly a U-turn.

Also, the quote you referenced does absolutely nothing to show that RF regarded women as his mental equals. It just shows that he sometimes explained stuff to them -- not surprising, given that he presumably had some female students/colleagues.

In any case, whatever the merits of Feynman's position at the time, I'm bemused that anyone could find his views on this topic quoteworthy.
The shampoo aisle looks different if you have long hair.
"With the adoption of the new gTLD system, which enables the direct utilization of the Canon brand, Canon hopes to globally integrate open communication policies that are intuitive and easier to remember compared with existing domain names such as "canon.com.""

Yeah, because canon.com is really unintuitive and hard to remember.

Besides, I'm thinking lots of confusion will ensue. You see a TV ad: "Visit us on the web at canon!"
Typical human being: "Well, what's their address? They forgot to tell!"
I've long been a fan of logos on maps as an advertising opportunity that can also add value to the user. Over and above making it known that a store they may want is nearby, store signage helps with directions and navigation.

After all, which is more obvious to someone driving - a street sign or a McDonalds? So put golden arches on every GPS / UBD.
While I don't doubt that hitting Karl Rove is effective (because you don't have to push buttons which are emotional for everyone, you just have to push buttons which are really emotional for at least some folks who control links), I just have a quick comment to make: be careful about attributing your own views to the population at large.

(The overwhelming majority of Americans do not know who Rove is and a large portion of the remainder will vaguely remember "Political something-or-other, right? Helped get Obama elected?" Of those who actually know who he is, many come from that weird niche market called "the other half of the country.")
The general public already has enough trouble remembering what sites are .com, .net, and .org, and most are flummoxed by amusing uses of other national TLDs. What purpose can this possibly serve Canon other than as a status symbol?
What's up fnid2. We've definitely had some known issues over the past several months at different levels in our system. We've worked out a lot of problems and are on top of others as we speak.

That said, Flightcaster works now for a lot of cases, but it is inherently probabilistic, so we do mispredict as well.

Keep using it, report issues to us when we are wrong, and we'll keep working on the algorithm and making our data better.
How Privacy Vanishes Online, a Bit at a Time
Look at what the service is about...Google maps has nothing to do with the cool parts of a site for tracking fitness and analyzing performance. It's just a tool to visualize a route. Google has no interest in a niche market like interfacing with proprietary fitness logging devices. They just provide tools to let us niche developers put out things which will display their ads and generate revenue.
This really is going to be like the early days of the Internet all over again.
Exploitation Driven Software Development
Ask HN: Ethics and the "hacking system" Q from YC application
Hey guys, had a general question for you. For those who have applied or seen YC's app, theres a question that asks: Please tell us about the time you most successfully hacked some (non-computer) system to your advantage.

PG writes: If this wasn't already clear, we're not looking for the sort of obedient, middle-of-the-road people that big companies tend to hire. We're looking for people who like to beat the system.

Naturally, beating the system requires some form of deception (some degrees of lieing, cheating, dishonesty). The "system" was setup in a way to obviously prevent that, which is why it exists in the first place. I know it doesn't necessarily make you an unethical or a bad person if you beat a system. But someone reviewing my previous application made a good point that PG puts a lot of value in the "Don't be evil" mantra, and said that our hack the system examples were shady. So I thought about trying to balance the amount of shadiness with the amount of beating the system-ness. (To be clear, one answer was getting around a library system to fake returning a lost library book in the 6th grade. Another was bait and switch trade technique to get items in Diablo 2. Not super evil stuff, we were kids and had to be creative.)

Now I don't want this to be a discussion about what I wrote, I just wanted to provide context for my question. On one hand, PG wants people who beat the system. On the other hand, someone told me PG is high on ethics. These seem to contradict one another. Which side is more powerful and more important in making an impression? Thanks
When I shop for shampoo I look for two things: unscented, cheap as possible.

What cares what brand it is?
On top of that, the article says they've got settlement-free peering agreements with many top tier ISPs, which is almost a requirement for a bandwidth-intensive service like this. I'm sure it still costs them in the neighborhood of $500k/mo after all is said and done to run this backbone with all the equipment, space, power, telco fees, etc. It's rather impressive they pull this off with a staff of 32 according to TechCrunch.
Because I am fine with the government doing things I do not agree with -- this is why we have elections. The point isn't to get into some kind of spitting match over who did what when. Let's stipulate that duly elected officials acting within the constitution instructed the CIA to do things we do not like.

To respond to the fact we don't like it, we elect new officials. We do not terminate the entire national intelligence program. After all, the next bunch of guys in Washington may need a CIA due to no fault of our own, and it take decades to spin one up. Trashing it in a moment of political anger takes away options we might need 20 years from now.
>I'm genuinely curious if anyone has studied the differences in the sexes when it comes to math.

Well yeh, tons of people have studied it:

Interesting. Can you tell me which tools you use to work around Garmin? Mac compatible? Are their formats proprietary? Would be stoked for a solution.
Doesn't matter. Most will be found by Google search.
I'm sure this will break a ridiculous number of regular expressions for email address validation.
I think I've read every post on highscalability.com, and this is by far the most deep and detailed writeup they've done. Lots of insight into the huge scale of justin.tv and what it takes to push that kind of traffic.

Highlight for me was discovering twicecache. Love the narrow scope and "fit" for the job it's intended for.
I'm going for nikon.is-so-much-better-than.canon

Look up the story behind Facebook. Its not like Mark Zuckerberg had an idea, wrote it up, and approached investors.

He executed, plain and simple.
There are lots of competitors in this space: http://timetomeet.info, http://www.needtomeet.com, http://www.convoko.com, plus the ones already mentioned.

The "meeting times" apps are becoming as numerous as project management apps and URL shorteners.
Unfortunately, I think the current socio-economic system can not allow that, even if it is the logical conclusion. Of course people would still do challenging tasks (or "work"), but not for material rewards.
> Washington may need a CIA

For what? What have they EVER gotten right? This utterly failed 60 year experiment needs to be shut down. The actual intelligence functions should be absorbed into the pentagon with a much smaller budget.
didnt the jruby team leave when bought by sun and start engineyard?
Awesome. You might want to note so somewhere in the site? I guess I'm not the only one who wants to make the comment.
I have read the statistics before-- in the 70's 70% of their calories came from rice alone, and even now, nearly half their calories come from rice and over 70% from carbohydrates in general.

I've also lived with several Japanese people. A bowl of rice is eaten at almost every single meal, including breakfast. It is true that the diet has become westernized and meat and fat consumption have gone up in the past 40 years... but so have their rates of heart disease and diabetes.

I don't have as much familiarity with HK diets, but they are also eat rice, noodles or dumplings at almost every meal, and eat less meat, and dairy than Americans. Having lived most my adult life in Taiwan, I can say with absolute certainty that from this side of the world, the US diet looks absurdly high in meat and junk food and severely lacking in whole grains, vegetables and fiber.

Edit: It's also uncommon for people here to worry about adding more protein and more meat to their diets like people in English speaking countries do. It's not even on the radar.
Nope. That's only T-Mobile. If you buy the Nexus One, you're best to also pick up the next iPhone at $200 and sell it for $700, to make up for the extra 20 bucks a month you'll be paying for the next two years.
I'll let you draw your own conclusions based on that.

Ah, the wonders of in vitro fertilization.

caring what brand it is helps when you have a hundred different kinds of shampoo to pick from. So me. I care what brand.

That said, all I want from the brand is to know they make decent shampoo that does the job without poisoning me, and offer unscented cheap shampoo. Their brand is simply a way for me to identify an easily locatable subset of shampoo that I can trust will posses a bottle meeting my desires.
Yes, but that is their own fault for trying to use a regex to validate email addresses. :)
I think your examples are pretty 'light', and not in any way detrimental, but I could be wrong.

To me it is as simple as 'whitehat/blackhat' hacking.

And what you did when you were a kid should be taken with a grain of salt, there is a reason we keep childrens criminal records sealed.
Sure you could, but while you're busy trying to find the exact combination of spacing and punctuation that starts the loop you want, and then manually looking through the loop to find every further reference to the same variable, the guy who called it "ii" and found it with the first four keystrokes is already being productive.

As I said before, it's probably not as useful with modern IDEs that have semantic search capabilities, but there is a genuine reason some people prefer the "ii" style.
Because the title wouldn't have that incredulous tone if the "them" referred to men.
They should update those mental modality books and put in programming.

Two recent studies directly address the question of whether greater male variability in mathematics is a ubiquitous phenomenon. Machin and Pekkarinen (19) reported that the M:F VR in mathematics was significantly >1.00 at the P < 0.05 level among 15-year-old students in 34 of 40 countries participating in the 2003 PISA and among 13-year-old students in 33 of 50 countries participating in the 2003 Trends in International Mathematics and Science Study (TIMSS). However, these data also indicated that the math VR was significantly less than or insignificantly different from 1.00 for some of the countries that participated in these assessments (e.g., Table 2), a finding inconsistent with the Greater Male Variability Hypothesis.

...

Similarly, Penner's cross-nation analysis of the 1995 TIMSS data (20) showed that the proportion of girls scoring above the 95th percentile positively and significantly correlated with several measures of female equality and status, including equity in educational opportunities and representation in the labor force and political offices.

Consequences in High School and College of Sex Differences in Mathematical Reasoning Ability: A Longitudinal Perspective
Camilla Persson Benbow and Julian C. Stanley
The Johns Hopkins University

Between 1972 and 1974 the Study of Mathematically Precocious Youth (SMPY) identified over 2,000 7th and 8th graders who scored as well as a national sample of 11th and 12th grade females on the College Board’s Scholastic Aptitude Test (SAT) Mathematics or Verbal tests. A substantial sex difference in mathematical reasoning ability was found (Benbow & Stanley, 1980b, 1981). The consequences and development of this sex difference over the following 5 years were investigated longitudinally. Over 91 percent (1,996 out of 2,188 SMPY students) participated. This study established that the sex difference persisted over several years and was related to subsequent sex differences in mathematics achievement. The sex difference in mathematics did not reflect differential mathematics course taking. The abilities of males developed more rapidly than those of females. Sex differences favoring males were found in participation in mathematics, performance on the SAT-M, and taking of and performance on mathematics achievement and Advanced Placement Program examinations. SMPY females received better grades in their mathematics courses than SMPY males did. Few significant sex differences were found in attitudes toward mathematics.
