Haha, thanks for sharing. I do think it's kind of odd that that woman would do something like that. You don't generally approach random people and boast about the accomplishments of your children. In my mom's case, she socializes at church and a line dancing group, so no doubt they're always talking about their kids.

I do think you've picked up on something with the whole social status angle, but I can't say I have a good understanding of it. Chinese moms are deeply invested in their children's education, and no doubt they judge themselves (and each other) by how much their children have achieved.

The sad thing is that some of those women may actually have been unimpressed by a Berkeley grad. You no doubt are aware of the tutoring centers that dot the Valley, catering to Asian students and their demanding parental units. Besides AP and SAT prep, some of these places also offer "college counseling" that runs many thousands of dollars over several years.

My sister, who is quite a bit younger than me, is on the verge of applying to college. Last time I was at home, my parents had collected a pile of brochures from these tutoring places, which advertise successful applications to Stanford, UofC, UPenn, and the Ivy League. The UCs are an afterthought. It's all about the exclusive brand names, if you will.

I'm just thankful I never had to deal with any of this madness.

I'm glad to see other people working on this problem. We (Wolfram|Alpha) are doing this too, starting out with the making the 'easy cases' nearly automatic.

Here's a blog-post describing our effort: http://blog.wolframalpha.com/2012/02/09/launching-a-democrat...

You can also play around with our examples without having to sign up to Wolfram|Alpha Pro. My favorite is an automatic analysis of the Titanic data that nicely illustrates that while the motto "women and children first" applied, being rich certainly helped: http://www.wolframalpha.com/input/?i=+&examplefile=1&...

We cover other kinds of simple analysis and visualization too, like heat maps, Venn diagrams, graphs, and so on. As always, feedback welcome.
What I disapprove of most with this is that it totally flies in the face of existing competition laws, that exist to protect the consumer.

In any other situation this would not be allowed to happen, and that it actually has happened (amongst all the other things, like the excessive promotion and monopolisation of unhealthy food and drink) makes me resent both the Olympics and the government that gave them so much of a free pass.

The sheer amount of corporatism and hypocrisy depresses me.
Not true. I just started "Katy Perry - Part of Me" (if anything will block you it'll be a high profile video like that) via Mobile Safari. Works fine, on both vevo.com and through youtube.com. You never leave MobileSafari, playback occurs entirely within the browser.

Apparently devs haven't been using their devices for much video playback. Most of the information on this page is a good six months out of date. VEVO and YouTube work just fine through the browser, and they have already devised a scheme to feed unskippable ads to iOS devices.

The industry is way ahead of the concerns on this page.
I started out saying 'Oh really!?' and then realized it was pretty well done satire. When I hit this quote:

“I don’t think we should be too quick to use the word ‘scientist’ here. Honestly, anyone can grow a Mohawk and put on a headset and look cool and all, but that hardly makes you a scientist. Let’s see some of these dudes discover a particle or something along those lines. I mean, come on.”

I just knew it was not serious.

Thank you for the answer, byuu. Don't get me wrong, your emulator is great, and I apreciate very much your commitment with open source. I simply pointed about the Nesticle patches were not necessary for speeding up the emulation, and that 3GHz was overkill, in my opinion. I bet in the future it will be much faster, no mater if is optimized by yourself o by others (I understand that may be optimization is not your goal, my point is just that the 3GHz is not a requirement just because precission, but because of current implementation). Best regards, and please, excuse me for telling you "idiot" in a previous post, change it by "innacurate" (Nesticle thing) and "incomplete" (3GHz required not only because accuracy, but also because current implementation limitations).
"For people whose jobs involve statistical analysis, how much need is there for something like this?"

I don't know who the creators are targeting, but perhaps it's not experienced people? One of the great parts of the internet is the way it seems to lower the barrier of entry for just about everything. If this app can help people learn how to do simple statistical analysis, there just might be a load of value there. I didn't really click around, but something they might think about doing is allowing users to hyperlink directly to an "analysis session" so a blogger can not only link to a graph, but the data itself. I can imagine a scenario where a blogger writes a post about maybe housing prices, and draws some unreasonable conclusion. Then a reader goes, and adds in inflation data which changes the story. He then replies in the comments with a link to his new "analysis session" spurring a new conversation.

Its probably taking the tool to a different direction, but i really like what's here.
The other question is if this behavior is not in the end leading people to shift back to cash payments again. I never understood the popularity of offline credit card payments. In fact I never used my credit card for anything outside of online payments, except for one situation where I had to come up with a relatively large and time sensitive on-spot payment. This minor factor of not having to spend each week two minutes at an ATM seems almost ridiculous in contrast to the severe privacy issues ( http://www.techdirt.com/articles/20120619/04094319383/data-m... ).
I think Mars Rover deserves more attention than that of Olympics.
They show up in regular searches via MobileSafari too, GP's assertion is completely incorrect. Vevo videos, unless artificially restricted by their owners, play just fine in MobileSafari.

It used to be the case there were lots of places that wouldn't accept mastercard. It's rarer these days, but I still run into them. It would never occur to me to ever travel anywhere outside my local neighborhood without both Mastercard and a Visa. And I realize that 50%+ of the time my Amex (which, of course, is what I need to use for corporate travel) - won't be accepted at smaller places. Expense Report Hell...
"Were there ATMs at the Olympics that would dispense cash from a non-Visa card?"

Actually, no there weren't! Visa insisted that any ATMs that accepted other cards were removed from the venues. This lead to a marvellous screw-up when all of the Visa card machines at one venue went down and there were only 8 freshly installed Visa ATMs to handle the crowds (which replaced 27 that had been removed): http://news.sky.com/story/966545/olympics-anger-as-visa-card...

The author's agenda in the article leads to some dubious claims. For example, I am not sure how Sufis bringing coffee from Ethiopa to the rest of the world justifies saying they "invented" it. Also, the ancient Athenians would seem to have a somewhat better claim for inventing democracy -- a millenium before Islam appeared.

It really depends on the currency. The odds of Euros, say, going "bad" on a scale of months to years are fairly nonzero. Similar for currencies with high inflation rates.

Apple has already made huge inroads to content production already by starting their book publishing house. For better or worse, this is a logical extension of that strategy.
Great post Josh. Keep killing it Alex, Boris and FundersClub team :)
Wow dude, you are ANGRY about something... that's fine, I get it, but you might consider looking into what that's about. It can't be much fun going through life pretending you want to fight everyone. To each their own I suppose.
From the comments I've seen in other discussions about this, people are entirely capable of reading all the warning labels and still failing to realise that swallowing these is actually far more dangerous than swallowing other metal objects.

They just seem to see the warning labels as an example of "health and safety gone mad" so to speak, of someone putting unnecessary warnings on about something that obviously can't be that dangerous. I can't see a good way of avoiding this problem.

Edit: Apparently there were similar comments in the previous HN discussion; at least one person[1] failed to grasp how much more dangerous they were if swallowed than other objects despite reading a 14-page complaint that described in graphic detail the exact mechanism by which they were more dangerous, the serious medical consequences, the long-term health risks even with prompt and successful surgery, and the history of kids being injured in this fashion by them. They're basically impossible to sell safely.

I'm sure that Visa has run the numbers and has a sound business reason for doing this

There's also something to be said for this being a memorable experience for most consumers at the Olympics. I'm sure Visa damned well knows that a number of people will always remember using their Visa card at the Olympics.
You're right, they shouldn't be making that average. Specifically, Likert data is ordinal, meaning 14 is less than 15 and greater than 13, but the gap between 15 and 14 may be different than 14 and 13.

For example, let's say people measure neuroticism exponentially, and an increase of one point means 10x perceived neuroticism. Because mean(log(x)) != log(mean(x)), the average won't be representative.

Everything else looks OK though: count, median, percentiles, a histogram.
I've been having enormous trouble understanding the thinking behind the "We are proud to only accept Visa" marketing campaign. I simply can't understand how it could be viewed positively by any consumer - it's such an obviously anti-customer thing to do.

I've been trying really hard to understand why Visa would make such an obviously unfriendly and counter-productive decision. The only theory I can come up with is that their real customers are the banks, and this is their way of saying to them "We're so completely ruthless that you're better off doing deals with us than anyone else". Seems a bit far-fetched though.
Some of the people dying on roads are suicides.

Very few are murders. Murders and accidents are not the same thing and not equally bad.

One difference: if you don't do anything about accidents, the rate stays the same. If you don't do anything about murder and just let it happen, the rate goes up as more people realize they can get away with it and serial killers or terrorists get more bold.
I totally read that headline as "Great, work visa, now I hate you." Was expecting an immigration rant.
But this Visa deal, what on earth are people without Visa supposed to do?

I do not have a Visa card. I have one Mastercard and one Discover card, plus my PayPal credit/debit card which is also Mastercard. The only Visa I've had in years have been those prepaid rebate cards.

But I don't think it's VISA that we should be blaming but the Olympic Committee that agreed to this and the McDonald's deals. They didn't have to accept those conditions.
I don't think I'd view book publishing as content production - a better analogy would be if they had writers on staff, writing the books, which they don't, as far as I'm aware.
Very true. I would even say those go hand-in-hand. I kind of doubt they would have been so easily grandfathered in if they had not spent insane amounts of money to get there. :)
What the? I'm surprised they could actually pull this off - they must've spent a lot of money on it. In Europe, MasterCard is much more popular than Visa (the latter is used mostly for credit cards, and most Europeans use debit cards) - I'm thinking there are a whole lot of other people cursing the company right now, too. Good going, Visa...
Not true. When was the last time anyone on this page actually used these services?

They solved this problem a while ago. Try it out. Grab your iOS device, search a VEVO video in MobileSafari. Assuming the owner didn't block all mobile playback, it'll play just fine, including a pre-roll ad that you can't skip.

The YouTube app for iOS devices only lists fully unprotected videos with no advertising or restrictions. However, MobileSafari has never had this restriction and has offered ad-supported YouTube videos via HTML5 for quite some time now.
That http://games.amazon.com/ is tied into Facebook apps and not the Amazon Fire[1] really shows the commitment to their own platform.

Very cool. It's interesting to note that Elevator Dispatch Algorithms are very similar to harddisk read/write algorithms. Hard drives have to accept read ("pick up") and write ("drop off") requests at different disk addresses ("floors") and figure out the most efficient way to handle all of the requests. In this analogy, traditional hard disks are simply very, very tall buildings wrapped around a cylinder.
Let me put it this way: I have seen prominent feminists label other self-identified feminists as not really feminist because they care too much about male rape victims. I have never seen it happen to anyone because they cared too little about them, for values of "cared too little" up to and including contemplating the systematic mass rape of men in order to teach them what women experience (the feminists in question abandoned the idea because obviously men couldn't really be hurt by being raped, not like women are).

Hell, I've know of one prominent feminist blogger who thinks it'd be a great idea to reclassify anal rape as something that isn't really rape, even when the victims are women, just so that no man could ever claim to have been raped. This still caused infinitely less controversial than treating men as human beings with feelings does.

This is an interesting concept but half baked. The biggest challenge to folks exercising their options seems to be the tax hit from AMT rather than coming up with the funds to buy the stock.

After the down-votes: Look at this this way, you get 200,000 shares in an ISO when you start at this startup. The valuation gives you a strike price of say a 5 cents per share. Now two years later you have vested 100,000 shares and you are leaving the company, and the company has gone through another round of funding and the strike price is not 10 cents per share. The cost to borrow is : 100,000 * .05 or $5,000 and the 'gain' in value is also $5,000. You pay AMT on the gain of 35% * 5000 or $1,750 in tax (Which ESO didn't loan you). Now your company exits in an acquihire or something and you're common stock is worthless. You're out $1,750 in tax, except ESO forgives the loan they gave you, that is another $5000 in income you have to report and $2,500 in tax due. So At the end of this you're out $4,250. Win? (You do get a $3000 capital gains loss you can write off that year from your adjusted gross income, only covers a bit more than half the $5,000 fogiveness income. So maybe you end up paying only $2,750 in taxes. Oh and you had to itemize which meant you spent probably double the amount of time you normally do on your taxes.

That is what I mean by 'half baked', coming up with the funds to buy the stock is only half the problem.
All I really see above is some hand waving justifying why your income should be charged for, yet for some reason some other person (musician) somehow is in the wrong for expecting other people to pay for their service and time it took to create their music for your entertainment.
In socialist Europe, banks own YOU! :-). But seriously, the banks screw with their customers so much over here that this is just another bump on the road.
To me, "proud to only accept Visa" sounds like "F@#k you MasterCard and your users, too"...
> I discovered that McDonalds’ terms of sponsoring included that no one else in the areas of the games is allowed to sell french fries, unless they come with fried fish (because the classic dish of Fish & Chips could not be banned in the UK). But besides the Fish & Chips exception, no one is allowed to sell french fries around the games.

My friend dealt with sponsorships in the venues for the Vancouver 2010 Olympics.

One of her tasks was getting the venue menus signed off on by the sponsors.

One of the food vendors wanted to serve potato wedges at the venue.

But because McDonald's was one of the 2010 title sponsors, and they had the same "no french fries" clause, my friend spent ~6 months of her life negotiating with the McD's folks over the difference between potato wedges and french fries.

In the end, the vendor got to serve potato wedges, but McD's got a ton of concessions in exchange (better signage location, etc etc).
They'll disappear automatically when you stop sending data about them (within a few hours) - we've done that for our customers who have elastic / rolling servers on AWS for ex.

I never got this attitude. "They are expanding beyond their core base, they shouldn't do that!" Why, exactly, this is the case mystifies me. A) Amazon is a better judge than anyone on what they can or cannot do, let alone should and shouldn't. B) Diversification is simply good business. C) Amazon is not expanding into drastically new markets. If anything, their initial jump into selling software (AWS) was a riskier proposition because it was unlike anything Amazon had done before, and a relatively untried business.

Finally: People scoffed at the iPod and iPhone when they came out; it wasn't Apple's business to go into consumer electronics or even telecoms. The Michelin Tires company produces the most widely respected restaurant guide. Clearly, someone should have put a stop to them - they shouldn't have done that.

Much like Bic is the maker for cheap, plastic tools (pens, razors, lighters), I don't see why Amazon can't continue to write software. There is virtually no risk and minimal investment.
Try Android. It is a much larger platform and much more affordable for teens.
I think this is not a great business model. You are planning to take the distributor portion of revenue but also take the additional risk of making the art. This could maybe be okay by itself but probably not. However, additionally it sounds like you want to bring xblig quality games made by young people to ios. Something like 90% of xblig games make less than $200, on the more competitive ios app store they will probably make less.

You need to change your business model drastically for this to succeed. I don't think you will break even with the current business model, much less make a profit.

Most people's first 4 video games fail spectacularly, the younger they are the more likely this is.

There are some exceptions but I doubt they will cover your mounting losses. I am the only person I have ever heard of whose first video game made it on to Steam, but while my game made it on I think many many games did not. Also I was a grad student in engineering at the time, not a high school student. You are essentially trying to VC video game development but only take 30%. This will not work with a 30% cut, and it won't work anyway unless you become a lot more selective on which games you choose to invest in.
They already exist, problem is the penalties don't kick in unless you counterfile to restore your content, and then take the original requestor to court for filing notices in bad faith, something that requires one hell of a case to prove.

I'd be perfectly fine with lobbying for penalties for accidental takedowns, though. You have the power to take down anything anywhere in the USA, fine. You should be forced to take responsibility for that. As it stands, they can shrug and say "oops" and leave a trail of damage in their wake.
Edit: I just realized for my math below I used 2^32 as UINT32_MAX instead of 2^32 - 1. The rest of my reasoning holds up though.

>Especially with small arrays his implementation will return the the 0th or 1st element much much more often than other elements.

Much, much more often? Correct me if my reasoning is wrong, but for a, say, 6 element array, this bug would make a difference less than 0.0000001% of the time ((UINT32_MAX%6)/UINT32_MAX). For a 3 element array, it would make a difference about 0.000000023% of the time. Maybe you mean by small "less than 100 elements", in which case the worst case is 96 elements, where it happens a whopping 0.0000015% of the time.

Indeed, the problem is only pronounced for large arrays, because that's when there's an opportunity for UINT32_MAX%N to be large (since A%B < B). There is no case where the 0th and 1st element are significantly skewed ahead of everything else. The bias is characterized by the last few elements of the array being selected significantly less often, but the "significantly" part only kicks in for very big arrays.

In fact, the first array length for which you will even see a difference 0.01% of the time would be 430,142 elements [ed: this holds up even adjusting UINT32_MAX to the correct value]. Considering that this is a framework intended to be used for iOS development, I think once your NSArray has grown that large, you might have more important fish to fry than worrying about a small bias in your randomization.
Thanks for the comment.

Agreed, Likerts are definitely an area of controversy.

A couple references from Wikipedia about Likert-as-continuous:

Pro: http://www.ncbi.nlm.nih.gov/pubmed/20146096

Con: http://xa.yimg.com/kq/groups/18751725/128169439/name/1Likert...

Our stance is generally a pragmatic one. It's very common practice to analyze data this way, so we enable it. But if you want to analyze your Likerts as ordinal data, you can change the variable type to Ranks (ie Ordinal), where we handle the result as you'd expect (nonparametric test, no averages). Note that this feature is disabled in the demo.

Thanks!

That doesn't look very "simple".
