You write:

"At least in most western countries and Japan where successful people have less children. It's almost like an anti survival of the fittest, if you are successful, less people in the next generation will carry your genes."

One interesting scenario you should consider are situations where a researcher comes up with a game theory scenario that they would like to do research with, but the people who play the scenario are smarter than the researcher. The question then arises - can the researcher correctly analyze the strategies pursued by the players? It's an interesting problem for game theorists - the researcher might conclude that the players are making the "wrong" decision, but in fact, since the players are more intelligent than the researcher, they've actually seen nuances in the various options that the researcher did not see when the researcher first designed the scenario.

For a point of comparison, imagine 2 grand masters play a game of chess. One of them wins and one of them loses. Now give a recording of the game to a chess novice. The novice can obviously repeat what moves that happened, but can the novice correctly analyze the game and determine what the losing decision was? Does the novice have the skill to correctly understand whatever gambit the losing master was trying to pursue? Can the novice correctly figure out what the decisive move (or moves) was?

I do not mean to insult your intelligence, but you should consider whether the successful, intelligent couples "in most western countries and Japan" are in fact paying attention to nuances that you have overlooked? Just to throw out some random possibilities (I am not arguing for any of these, only pointing them out):

1.) the path to reproductive success is to make greater investment in less children (more resources per child, given less children)

2.) less children per parent leads to greater health for the child

3.) successful men who marry successful women are secretly (or openly) promiscuous when they are young and have more children than are recognized

Again, I'm not saying any of these 3 options are true, I'm just saying there may be game moves that the very intelligent are considering, which maybe you have overlooked. I'd be cautious about assuming that the most intelligent members of the species are making all of the wrong moves in the game of life.

Tegra is ARM based, and with the low end part using 300%-400% more than the tegra 2 they are clearly for different devices.

Atom is more or less the comparable part. If you're wanting to compare to an atom based SOC that's Sodaville or the CE4100 which is the chip they switched to for the boxee box.

I currently work in Higher-ed and I'm really excited to see what the long term effects of things like OCW and the Khan academy are going to have on education. The simplest benefit is mediocre teachers will have a harder time hiding their incompetency, and all students will have access to the best teachers. When I took my algorithms class I followed along with the MIT lectures. My prof was okay, but nowhere near the level of competency of the L from CLRS and Erik Demaine.

More interesting is the challenge these things pose to the authority of the entire system of higher education. What's going to happen when most top student at non-top schools get most of their lecture materials from someplace else? I can easily imagine a near future where most interested undergrad calc students learn from Sal Khan and only show up to class for exams. What does a degree mean when one student has done the exact same course work as another only for free? Autodidacts previously had suffered somewhat from lacking structured course work, but that problem is resolved. If you're motivated enough you can design your own education path which will most likely be more efficient than traditional ones.

The obvious answer for higher-ed is to capitalize on what OCW and Khan can't offer: office hours, peer interaction, working on a research team, and lab time. Unfortunately, universities are almost incapable of rapid adaptation to change (we still put on silly medieval hats when we graduate).

But everyone was still sub-average by "normal" standards.

If this actually happens, you're likely to see an intellectual upper class that is more intelligent than the current average. Selection works both ways, and even if the intelligentsia reproduce more slowly, they still reproduce (mostly) within their own group, leading to ever-smarter offspring.

Assuming genetic factors dominate intelligence anyway.
Freakonomics: Game Theory and Child-Rearing
I can't give you my exact campaign that's wasn't what this was for :p and that will impact my company negatively if more people are knowledgeable of my exact methods of monetization via my data.

Stop worrying about my users mate...just do what I did looked at your data, worry about your userbase. Not going to elaborate on how insanely inaccurate alexa is but the site is very new so you can't look at my ranking at all I have sites getting 100,000 visits a day with a Alexa ranking of 120,000k and a site that gets 10,000 visits with an ranking of 50k. It's usually somewhat accurate after a few months and the ranking is below 10,000 other than that I don't look at Alexa at all.
I posted this because it's a fun paper, and implementing object-systems is a fun project for the millions of newbie Lispers and on-the-fence programming language nerds out there.

The unique feature of this paper is that it uses simulation, as opposed to compilation or interpretation, in order to extend a language. I have been saying this for years, language implementation techniques as presented in undergrad studies are actually HARD; the fun, easy techniques are buried in "research" papers like this one.
First, it's "conscience", not "conscious".

Second, the word "innocuous" means "harmless", not "not intended to offend".

It's quite obvious that the original comment was not intended to offend anyone. The guy who made it was probably oblivious to its potential offensiveness.

But that doesn't mean it was harmless. He was basically advocating making bribery easier, which is not only offensive to many people (no matter what his intentions were), but could very well make the world worse if people start acting to make what he's advocating a reality.

That said, kudos to your volunteering efforts and donations. More people should follow your example.
Reason #3 shows that the author does not understand even the basics of virtual goods and facebook platform monetization. The other points are nearly as non-sensical.
A genetic factor, sure, but the question is not whether there is a genetic factor, but whether that is what is selected on, given the "stupid/lower class people reproduce faster" assumption.
>Usually:. Posts about posting and karma in the middle of other threads are generally viewed as non-contributing.

If that is the case then why did the person who created a thread flaming me and complaining about posts, benefit from probably 100 karma pts today?
that's true, but back then we probably all used fax machines for sending messages. times move on, and so does the level of interaction with the machines. eventually the number of people who understand this will be even smaller than now, that's not a bad thing, it's a sign of progress.

I gotta wonder about this and their relationship with Apple. Apple can't really use it because they also have a large ARM presence and Intel isn't going to give it to ARM. Heck, Microsoft is in the same boat. Who exactly is going to be able to use this? set-top boxes?
I asked this of a friend who went to SVA in New York for graphic design. He said that the real benefit of an excellent, yet expensive, college, is in learning from real people and having the course tailored to the current situation. He said the students, while talented, weren't any different from those at another college. Sure, you can learn how to design by yourself, and many of the greats have, but it's much more efficient to learn from a master.

Feedback, really. A good college is partially about good company, and partially about great professors.

Right now there's a ton of information, but it's tantamount to books, and PBS videos. Once there's an online college, to help guide the student through the material, there'll be a real revolution. Until then, OpenCourseware will strictly be for those who know where they're going.
How about we compare the N1 (released Jan 5th, 2010) with the first gen iPhone (released June 29th, 2007)? Even the 2007 iPhone had smooth scrolling/compositing/animation and was always responsive to touch gestures. I'm pretty sure you can't claim a phone made three years before the N1 had an unfair technology advantage, right?

"And don't give me that crap about VCs being "early stage" and wanting to cash out of a "mature" investment. These people are as money hungry as any other institutional investor, and would let it ride unless….they saw something that suggested that the era of stupendous growth was over."

The author doesn't seem to understand how the venture asset class works.

Venture funds are owned by their limited partners (LPs), and typically have a fixed, 10-year life. After 10 years, the fund liquidates and the LPs (hopefully) get a nice return on their investment.

It's been 6.5 years since Facebook's first venture investments. If the investment vehicle was already 2-3 years old at that time, then they have to liquidate soon, even if the managing partners believe Facebook will continue to appreciate in value.

The author seems to think that anytime an investor wants to cash out, it's because they don't "believe" in the investment.
The dead-end streets in my neighborhood are physically narrower, too, probably for the same reason. AS a side effect, though, it gets hard for delivery trucks and snow plows to turn around and get back on the main road..

But everyone was still sub-average by "normal" standards.

You mean that everyone was sub-average by todays normal standards. But what was normal in the year 1435 is very different from what is normal in the year 2011, and again very different from what the norm will be in the year 2505.

Had Trevor and Carol been able to produce offspring, they (and the rest of their class) might have been able to bolster the norm. Alas, Trevor tragically met his demise with a heart attack whilst masturbating to produce sperm to artificially inseminate her.

Meanwhile, Clevon kept cleaving on, appreciably moving the needle on what 'norm' means.

Edit: We didn't get to see much inside of the Brawndo corporation, where all of the power was concentrated, so we can't be sure that President Camacho was the brightest around. All we got to see was the CEO, who may not have been the brightest bulb in the drawer. The descendants of the medical researchers bent on curing hair-loss and prolonging erections probably work in the bowels of that - or some other - corporation.

Ask HN: How to ensure co-founders work together in the same direction?
I am trying to find an efficient way for my co-founder and I to define and agree on requirements for our product and to execute our idea in the best way possible.

My co-founder and I are both technical and unfortunately geographically distributed which hampers communication.

Right now we have divided the application along natural lines with each of us pretty much coming up with our own requirements/architecture for our respective parts and discussing whenever necessary.

I feel this approach is going to get us into trouble or lead to an inconsistent/poor user experience for our customers.

How do you keep in sync with your co-founder and make sure you both move together in the same direction?
As a neophyte, the only thing I find missing is proof by cases, exhaustive proof (sometimes there are just a few cases that can be trivially proven separately, yet a comprehensive proof is elusive), and (while it's a bit tangential) a couple tips on how to read others' proofs (e.g., what do things like "clearly" and "without loss of generality" precisely mean in this context, and what to do when you encounter them).
My 2 cents - Facebook will be releasing a phone timed just right for their expected IPO in 2012 - my guess is that they wouldn't be able to approach any handset manufacturers directly without telegraphing their intentions to G and Apple - perhaps a social OS wrapper around Android ?
Second tip: posts whining about your karma hits or inability to grasp the flow of HN also do not yield you a lot of love.

but post and threads publicly flaming someone for making newbies mistakes does give you a lot of karma love I see.
Not at all. This article cites a gain of 0.3 points per year and postulates (admittedly without drawing any conclusions) that the average person in the early part of this century had an IQ of 80:

http://www.americanscientist.org/issues/id.881,y.0,no.,conte...

If we continue to extrapolate, we can conclude that 300 years ago people had an IQ of 10. Not very bright, but a significant improvement over their great-grandparents, who would have had an IQ of -20.

Because the price of the DVD reflects a whole different set of cost than digital distribution, and doesn't provide any incentive to the movie industry to do get with the programme and license their movies to digital media distribution hubs like netflix. I;m tired of seeing the same old movies touted on netflix streaming as 'new' simply because the movie industry cannot figure out a licensing arrangement...
As of right now no unfortunately but I might do a followup post showcasing some sketches/wireframes images.
Please don't dismiss the "literal, trivial interpretation". If you read the explanations that came with the flowchart, they try to make it very clear that "known" means "known to you".

Also consider the context. This was a handout to students in a first linear algebra class, that was meant to help them learn to do basic proofs on their homework problems. Nobody expected them to be engaged in original research. Any useful technique they needed to "discover" was very likely to be well-known to lots of people, including me.

Finally it is not clear to me why you think that the word "known" is superfluous. There is a world of difference between the stage where you are running through the techniques you know, trying to find one that fits, and the stage where you're engaged in expanding your list of available techniques. I was trying to get at that difference.

Nice idea but as someone who manages technology for a school I can say tablets just aren't there yet. A few things (that might not be apparent with 41 hand picked kids)...

==========

Damage: Understand that planning technology for a school is all about scale. It isn't about "Can we afford to buy this for each kid" its "can we afford to buy this for each kid and deal with a 30-40% damage rate". Because they're kids.

Remember the way you treated your backpack in Jr High and High School? Now imagine how a $750 iPad would have done if you carried it around all day.

Most hardware companies combat this by either (a) making devices durable or (b) making them easy to repair. The iPad is neither of those things.

Control: The problem with an iPad right now is there's no way to lock it down. If a student decides to start browsing the Internet while you're giving a lecture there's little you can do about it (why do you think most schools ban Cell. Phones at this point). It's hard to focus a class when their text book can also be used as a Game machine and Internet browser.

Software: The most obvious point is that Apple hasn't compensated for mass purchasing yet. I should be able to have a "Purchaser" account that allows me to log in to each system and install multiple copies of a given software package. At least the last time I investigated this option that process was a mess (At first it wouldn't let me pay for multiple copies of software because it said I'd already purchased it then it would lock me out because I'd installed it too many times and so on)

============

There were some other issues that are escaping me now but the bottom line is it's a great dream and a great opportunity for some startup. But just plain old stock iPads don't work.

Edit: A few I forgot...

- Power: You either have to find some way to power them during class (which requires rewiring the classroom) or limit their use. Plus kids forget the charger and use it as an excuse not to do homework or participate in class.

- Eye Strain: You'd be amazed how parents who park their kids in front of a TV all day will come back at you complaining they read a report that said extended viewing of an LCD screen is bad for the eyes.

- Updates: Since there are no over-the-air OS updates its a chore to update the things

- Kids Content: Since there's no way to lock kids out of the administrative functions of an iPad a few will just change the account to their iTunes account and start downloading media on it which causes all kinds of problems

- Theft: There's not much of a market for Jr High Text Books on ebay. The same can't be said for iPads.
