I understand the difference in web vs. desktop. In this case, the intent as it relates to MVP is the same. The example given measured market interest without a prototype, so there is no iterative deployment issue.

I can understand the apprehension about MVP. As a coder myself, it is not an obvious approach (vs. putting out an actual beta) and I've not yet tried it. I'm interested in other people's stories and experiences though, and I'm not inclined to downmod a constructive conversation about it.

Interesting. Men have more variance in aptitude but there is same amount of boys and girls in math olympics (in countries with gender equality).

That might mean that people able to achieve olympic level of math skill are actually abundant enough so small random pick from all available people with such potential does not show differences.
The author says that UW students taking Atmospheric Sciences s101 "should be the creme of the crop of our high school graduates with high GPAs".

1) Atmospheric Sciences 101 sounds like a "blowoff" class that liberal arts students would take only to fulfill a science requirement. In other words, the students are likely self-selected for lack of math/science ability.

2) UW is a public university. It may very well be the best public university in Washington, but I'd bet the best students have a nontrivial rate of private school attendance. (So as to dispel any illusions of elitism, I attended the University of Michigan, which is also a public research university.)
The switch of mobile devices from 2G/3G technology using IPv4 to LTE (aka 4G) using IPv6 will fix a large amount of this, "As IPv4 increasingly became the de facto standard for networked digital communication, the cost of embedding substantial computing power into handheld devices dropped. Mobile phones have become viable Internet hosts. New specifications of 4G devices require IPv6 addressing."

http://en.wikipedia.org/wiki/IPv4_address_exhaustion#Mobile_...

IPv4 runs as a subset of IPv6 for those of you not into the IP stuff too deep. IPv6 devices can talk to IPv4 through border devices similar to NAT today so we can use "private" RFC1918 addresses.

Pragmatics of Impurity
I'm just as upset with the state of math education in the US as anybody, but if UW is anything like my alma mater, then "Atmospheric Science 101" is a class that liberal arts majors take to satisfy their math & science general education requirements. A lot of these students (my wife, for example) have serious math anxiety. She could probably get a 70% on this test, even today, so many years after school, but throw it at her without warning on the first day of a non-math class and she'd literally cry.

Now there's a case to be made that a good high school math curriculum should not leave anyone anxious about math, but I still think it's a bit of a leap to take this test and extrapolate to all students.

I didn't realize 37signals had a service called Haystack. I assumed this post was about Facebook's Haystack photo storage system.
Sorry. Your original response made it sound like that's what you did do.

I knew, e.g., Facebook lets you search by email address to find a friend if you know their email. Since the data on Flowtown more-or-less matched that data I had assumed that was the source of the data.

You'd do the same for the other social networks, plus perhaps get data from Rapleaf and other social profile companies.

If you're saying that's not the case, I can't argue with that and apologize for implying otherwise.

As to whether it's a trick or not, what difference does it make? You can call it a tactic if you'd like.
Same experience with my girlfriend. She has a good analytical mind (she graduated near the top of her law class) but she's just terrified of math.

The weirdest aspects of this phenomenon are that: a) there's a very real fear of math unlike any other subject and b) there's no stigma against being mathematically illiterate as there is for other subjects (most likely because so many people just accept that "math is hard" and not for them).

(For what it's worth, I used to interact a lot with similar businesses when I was working for eBay plus I am currently running my own similar business).

Here are some tips:
1. Keep your costs very low while you are figuring out if there is a market. If possible, use sites like shopify, eBay, Amazon, etc to find some first buyers for minimal web development and only order a relatively small amount of inventory - hopefully you won't end up with a pile of un-saleable inventory while working out if this can sell.

2. If you can source the inventory cheaper than is the current market price, that can be a good advantage - but don't think that cost will be your only advantage without worrying about marketing etc.

3. When calculating your sale price, factor in fraud, refunds, wastage, etc. Regarding fraud, it seems like a regular occurence - be hesitant shipping large orders to unknown customers with unverifiable addresses.

Hope that helps.

I'm not entirely sure if the g-loading changes were made in the math portion, or just the verbal. As to how to decorrelate math, I suspect it canbe done by simply reducing the number of chained dependencies. For example, have one question involving sin(x) and another involving x^2, instead of one question involving sin(x^2).

I think Haystack is the better name of the two - stronger and punchier. Because the domain has a perception of greater value, I think the operators are perceived as more professional.

Sortfolio could be any old weekend 2.0 start-up that threw together two keywords and found a spare domain.

Still, I absolutely admire their ability (with the original concept) to leverage their brand and audience, create business leads for customers, and (most significantly) succeed with a stale, done-to-death idea (directory of businesses).

I think it's a reasonable barrier. Ant nests are fairly capable as reactive systems but limited by the inflexibility of the stigmergic control systems they're running on. I doubt such a substrate could implement true intelligence.

As for humans - "locked in" people are a special case, their outputs have been entirely disconnected (unlike dolphins). But we are pretty close to having the tech to reconnect them. Again, humans find a way around it.

Exception: there are humans who IMO do not qualify as people. That is, no measurement even with a mind-reading machine would call them sapient - they get grandfathered in because they share a species with us
He has described symptoms well, but his explanations only make sense if you ignore other immigrant groups. Latin American immigrants come from similar range of poor, politically unstable backgrounds, yet their children aren't being driven to academic excellence by their parents. In fact, instead of outperforming the white American natives, they substantially underperform them. Why the difference?

Let me give an answer: it appears to be genetics. Why else are the very different experiences of mainland Chinese, Chinese Hong Kongers, Chinese people from Taiwan, Chinese people from Singapore, Chinese people from Indonesian and Malaysia resulting in only minor differences in average outcomes in the USA?

Once more,

It's been shown that for a few cultures on a small norming sample on particular tests (IQ, SAT) that standard deviation on math related scores is greater than that for women. The bulk of the standard deviation is accounts for by people testing around the mean, because most of the scores are around the mean.

Knowledge of the standard deviation does not, as our financial markets recently showed, correlate so well with extreme outliers, as those with Olympic level abilities are likely to have. And the sorts of thinking demanded by those taking an IQ test or the SAT are not so similar to those required by Olympiad level problem solving (correlated and similar though they are). And the sort of thinking required of Olympiad level problems is not so similar to that required for success in research mathematics (helpful and correlated though they are), as shown by the large numbers of people who attain great honors in such competitions and do not end up really producing much original work. And it's been shown and is frankly straightforward to see how cultural influences can effect both interest and resources available for bright young minds of any background or gender.

We just don't know enough about one's aptitude and its interaction with the environment to make such blanket statements. Men have more variance in aptitude! It's like a difference of a standard deviation of 14.5 points for women and 15.5 points for men. Keep in mind also that a core component of most IQ tests and the SAT is time pressure. In the SAT it's raw time pressure, and in psychologist administered IQ tests you have several factor: one being an explicit time weighting, two being the the fact that the speed of one's response can give you a much higher score, three being that your answers are subjectively weighted by the psychologist (which could already introduce bias), and if you seem unsure you'll be docked points, and if you seem sure but speak vaguely you can often turn a yes into a no, and four whether or not they move forward in sections depends on how quickly you're answering. It's been shown by Benbow et. al. that, at least in America, girl's confidence with mathematics is astonishingly uncorrelated with their performance (unlike with boys, who, if they're good, tend to think they're even better.) It is completely reasonable that if you're more unsure about your own abilities you might hesitate for just a bit longer, sound a little less confident, hazard fewer guesses. This will, by itself, reduce variance in one's score. You'd need to account for only a 6% difference to explain the variance in score.

(Also, from what I know, too, the selection processes of countries like Romania, Bulgaria, Russia, Ukraine, Hungary, China, and the USA are anything but a random pick. They can be quite grueling, actually.)
If I understand correctly, the issue you see is not related to the AGPL version 3 only but also to the GPL version 3 as the "2. Basic Permissions" are shared between the two licenses. Could you point us to the specific section or sentence disallowing the freedon #0?

Regarding the "enforcement boundary", the AGPL is more there to not abuse the "private use" ("not conveying") of a free software as described here :

I don't understand how reducing chained dependencies will eliminate g loading.

If you eliminated g loading of a mathematical test, you'd need to be able to take a developmentally challenged person, and expect, statistically, for them to get the same score as a fields medalist. I just don't see how you're going to swing that.

RE: The Mensa site. They claim that the GRE and the SAT and the ACT no longer correlate with IQ. Or g. That's just wrong. The old SAT correlates positively with the new SAT. The old SAT correlates positively with g. You'd have to have an extremely unusual statistical correlation between the old SAT and some other variables to yield 0 correlation with g.

They could be concerned that it's less well correlated. Or that preparatory courses from Kaplan, et. al. were killing the correlation.

But in all seriousness, who's keeping count. There are pretty severe conceptual problems with g anyway. I mean, all it is is the principal factor in a kind of multivariate linear regression analysis of a bunch of scores on tests, which are arbitrarily selected and claimed to represent 'intelligence.' You can't expect that linear statistical relationships mapping a few scores from a few tests chosen ad hoc really capture the breadth and diversity and range of human intelligence. It's crazy! If we look for some linear relationship, we'll find it. But it can't possibly tell the whole story.
7 Gadgets That Will Ruin 2010
Is it any surprise, though? Math is taught in a manner that focuses very much on the how but rarely ever the why. And while Discovery Math/Reform Math/etc are lambasted for not teaching kids to memorize certain algorithms, they do something else that's very important: encourage students to use creative problem solving skills to develop their own solution algorithms.

I'm not going to advocate reform math in its current form, but I have to question traditional "drill and kill" teaching methods in today's modern world. If I can't remember how to find the area of a triangle, I just Google it. Drilling it into my brain would have made sense in the 1920's when there was no internet, no assurances my peers had the appropriate level of education to know such a thing, and possibly no ability to reach an "expert" via telephone to tell me the algorithm. I'd be completely reliant on my memory and (possibly) a math book if I was fortunate enough to have one with me. For all practical purposes, memorizing one half times base time height would have been the way to go in a pre-Internet era. Today, it seems like it's far more worthwhile to develop students who are solid problem solvers with strong information retrieval skills, as opposed to wasting precious time memorizing trivial algorithms that are readily available.

The Dark Side of the Late 2009 M&A Surge
I think of Twitter as a space to move large-scale messages to a broad public, rather than as a social net-working site. Twitter has proven effective in organizing political protests, encouraging feedback loops between companies and clients, and in allowing people to feel connected to celebrities (and whatever value that affords to people, although its economic value has been certainly proven by the brisk sales of tabloids). Perhaps the tag system allows people to connect with others who share similar ideas, but Wright is correct in saying that Twitter falls short of being email or IM in terms of meaningful communication. It's more of a "status" or information generating machine.

Maybe I have a limited view of Twitter, given that I have yet to figure out what it replaces in my life from email, Facebook, LinkedIn, Tumblr (microblog), WordPress, mobile, RSS feed manager, SMS, letters, and actually talking to friends in person or via another friend. A Nielsen wire report from April 2009 mentioned that 60% of new Twitter users fail to return each month, which averages out to about a 40% overall retention rate, whereas Myspace and Facebook are reportedly stable at around 70%.

Psychology research on the cognitive limits of stable relationships has generated an arbitrary Dunbar number of about 150 people, so Twitter followers/followees numbering in the 1000s seems suspect in terms of actual social ties. Average Twitter followers for each user has been reported at around 126, and Facebook is slightly higher, (not sure how those figures were calculated). But given that many Twitter users are celebrities, companies, or businesspeople, and Facebook celebrities/products tend to have fan pages rather than friend accounts, I think we need to see more descriptive statistics other than just the mean. Perhaps the problem here is one of defining and then agreeing upon which definition ought to constitute a "social network." Economics, psychology, marketing, and sociology all have contributed their version. But I still think Twitter is lacking in its delivery of service for the average user who isn't embroiled in business, celebrities, or political turmoil but is looking for a social networking space.
Advice you don't want to hear: finish school, pile up that debt, kick ass in those classes whose material you could "pick up on your own more easily."

The best kind of debt is school debt. If you leave school, you'll be piling up debt anyway, but not that kind that is easily forgivable. And those connections you're looking for? You get them at school - either by meeting classmates or professors, or showing future employers that diploma.

Like someone else mentions on here, the important thing is to learn to finish something. Your list of cool and interesting stuff you've studied is only cool and interesting to us here, not to your potential employers, even if any of us here were your potential employers.

Unless you've got somewhere else to go, school is the best place to be. And if you had somewhere else to go, you wouldn't be asking about it online.
