How do you do a statistical test against "mu is between a and b?"

If H0 (null hypothesis) is mu = a (and you know sigma = 1 and its normal) then you can pretty easily calculate the p value from an observation x by taking z = x - u and checking that against the normal distribution.

However, how do you do that is H0 is a < mu < b? Do you assume that mu is uniformly distributed between a and b? If so, then H' does not imply H. E.g. if H is true then pr(mu > 0) is 0.5, but if H' is true then pr(mu > 0) = 0.52/1.34 < 0.5.

Or, am I wrong about how to do the hypothesis test?
that was my first reaction, but this article is extremely long. wishing there was a "tl;dr;" section so i could figure out the conclusion in a sentence or two. bookmarked it for now, will come back to it.
Meh, John Galt went out and convinced all the rich people who were allegedly being preyed on by unions and special interests to.. go on strike? And become a special interest? Wow, that's great.

First off, if my boss left to go do that I'd say "Thanks for the promotion" and take the payraise.

Second off -- and much more importantly -- you should live your life for something more than your own crappy temporary luxuries.
Even if a startup was willing to sponsor you, having your immigration status contingent on the continued existence of a company that could go bankrupt with little notice doesn't seem like a good idea.
How long ago was this? uvcvideo was merged into mainline quite a while back, so almost all [recent] webcams should work pretty well now.
I wish I would've seen that the application window was opened sooner, so I wouldn't be one of those last-minute applications. That's what I get for thinking the HN front page would keep me up to date on YC activities ;). I'll be subscribing to the YC blog RSS feed now...
Wow. I sympathize with this very, very strongly. I think this captures the root of the career frustration that I experience 70% of the time.

I seem to spend way too much time on what I call "guessing the magic password" - tracking down that one bit of punctuation in some obscure value in some xml configuration file that makes my whole system fail silently in one environment. I might spend 5 hours beating my head against a wall, only to finally figure out that this brittle system over here needed me to put some proprietary prefix on some host name in this one context. And at the end of it, I don't feel accomplished. I feel like I'm wasting my life! Figuring out which parameters to pass to which APIs in what order is a step above "guessing the magic password" - but it's not that big a step.

A few things come to mind. You can try to make sure you are one of the people writing the libraries. You can implement the next platform and use all the aesthetic sense you have in you to try to make it a joy for others to use. Put yourself in the position of the programmers who write the systems that make the rest of us age faster, and try to do a better job. Or content yourself with getting your programming joy from your elegant side-projects.

But they say they expect you to last 6 months.So it is 1000 per month! I think that's what r238 meant.
Well, I can say that IE8 was a huge step forward, but if they listen to what I have said in my last post (that you responded to here), then that pretty much would solve a lot of problems that most developers have with it. I'm willing to give them another chance. However, here's the thing for me:

- Firefox comes with great addons, so even though it's slower than Chrome, it's still got me. Plus, Firefox renders form elements just slightly better for me in my opinion than Chrome does.

- I like Chrome a lot, however, for W3C and CSS3 compliance, for stability, and for raw speed. I would switch to it as my primary browser because of those reasons if it weren't for the fact that I just stated here about form element rendering and that it needs a few more critical addons. For instance, I use FireFTP like crazy, as well as adblock, Flashblock, and FireBug. I hear that much of this is coming, so Chrome may be my primary browser later on.

So, even if IE9 or IE10 turns out to be a pure delight as far as W3C and CSS3 compliance, it still has speed issues to overcome versus Chrome, infrequent release issues, cross-platform issues (Mac, Linux, Windows), etc.

But here's another thing, Microsoft hasn't been very nice to the F/OSS community. They have thrown a lot of mud up about patent infringement and junk, and I don't like software patents at all. They have been exposed in the Halloween docs and on Groklaw. So, the odds of me, an Ubuntu Linux user using a future IE release made for Linux -- well, that would be slim to none.
i didn't mean gmail adds--i mean, every add, on every site that uses adsense, ever.
I'm old and generally pessimistic. But I've seen enough recessions to know that when you've read the seventeenth article about the never-ending bottom (as I did during the reagan era, during the early 90s when Germany and Japan were going to destroy the US economy, and post dotcom collapse), I can't help but think it's time that the pundits will all be contradicted on the upside. Just like they were on the downside.

Nations that have demographics and immigration policies that promote population growth are going to succeed comparatively over the next 20 years. The US isn't at the top of the heap there, but its close.
What did they re-configure of re-program?
I find the menus ridiculous on OSX.
Totally agree. I thought it was great that it showed certain areas dying based on the way you build up the area.

However, I wonder what type of human logic is incorporated. Are they anticipating that people in the cities will be united, buy local, etc., or is it based on some type of historical precedents in urban planning?
Dell is effectively exiting any of massive-scale markets which rely on smart algorithms and redundant architectures on best-price commodity hardware.

I disagree; the massive-scale (DCS) customers generally don't use RAID controllers and they have enough clout to negotiate reasonable disk and RAM prices. Enterprise customers can also negotiate discounts. The people who are getting screwed are small customers (which was traditionally Dell's strongest market AFAIK).
How is that a stretch? They wanted to buy a bunch of tickets and not have anyone know. That's anonymity right there.
If you do those 2 things in conjunction, I doubt you'd have to worry about people "stealing" your IP.

And yet Google is potentially pulling out of China due to having its IP stolen.
It has not been directx vs opengl really. It's more of a direct3d vs opengl as they are really only renderers and not full stacks to build your game off. That being said, using opengl is smart to do because that is a tough part to get right and the other code(sound, input, networking) should have cross platform libraries or be easy enough to create from the native code.
Uh, the green bars also mark the change in price from $399 to $200. Don't you think that might have been partly responsible?
Sure, but it's beside my point, which is that the small g(uy|al) would be better off if lawyers were either obsoleted by a ``Law 2.0'' or made into a purely public resource.

> a. Through the use of fake email addresses, domains, and IPs, Wiseguys claimed to be over 1,000 different people.

If this becomes a crime then we're all in trouble. Who hasn't created a test account using a fake name, etc.? I don't want to be guilty of perjury or fraud because I created 2 digg accounts.

> b. The tickets say they are not allowed to be resold. I do not know the legal status of such claims, but you agree to those terms before the purchase, which removes one of the weak points of TOS enforcement.

I think TicketMaster would have been right to not honor these tickets then, but not sure how this could be a criminal offense.
Intelligent photo resizing and alteration
Grrr. Wikipedia protocols for notability are just terrible for FOSS projects, which is rather ironic. I'm still kinna peeved about the deletion of the StumpWM article.
Seems like the consensus is: "(10:30:18 PM) vish: the metacity buttons on the left is nothing more than trying to copy OSX :/".

I hope they have their own focus groups to back this up or something. Maybe they assume a Mac user is more likely to experiment and therefore more likely to try Ubuntu, so they would put the controls in their default place.

I'm not happy about that either. Otherwise, I think it looks fine.
It's extremely long? Maybe I'm a bit older than most readers here (I'm 38), but has the average readers attention span shrunk that much?

Nuance cannot always come in bite-sized chunks. BTW, I read the article (on a plane - the print edition, no less) - it's worth the time.
But if I had my friends buy all the tickets and I then tried to scalp them:

- It would be totally fair if the concert venue chose to not honor those scalped tickets since I violated their ToS, and if they told me what a d--- I was...

BUT

- I should not be arrested.
It's like working with the evil offspring of GridBagLayout and XML

That one had me laughing out loud. Ah.. Good ol' Java, I remember you. Anyway, as an iPhone dev looking to branch out into Android, I found this piece immensely useful, though I'm sure mileage may vary.
I like to think of an internship as a kind of apprenticeship. In some cases, the apprenticeship is worth it. For example, a tech internship at Google or Microsoft lets you work on some of the most widely used software in the world with some extremely competent people. In this instance perhaps being unpaid wouldn't really be a big deal -- the real value would be in the experience you get and the things you learn. Working for a college newspaper, however, is unlikely to provide a good CS student with anything more than they'd learn on their own with a rather useless name to drop at the end. While working for a college newspaper may be a high accomplishment in the journalism world, it doesn't really mean all that much in the tech world.

Also, Microsoft and Google pay. They pay a lot.
It's hard to argue that people cared that much about 3G back then, especially AT&T customers.

Many them weren't AT&T customers. That green bar also coincides with the release of the iPhone in 22 countries (as opposed to only 6 for the original model), expanding by another 48 by the end of the year.

My view is that the article is on the optimistic side.

It accurately describes the best case. It admits that nobody knows how bad it will be. But it fails to talk about known structural problems that we still face.

We have coming credit crunches in commercial real estate when ARM loans reset, prime home mortgages when ARM loans reset, private equity when principal comes due on a ton of LBOs, local government as their tax base continues to decrease, unfunded obligations increase, and they continue struggling under a major load of debt, and local governments as well as their pension funds suddenly lose large amounts of money due to overexposure to the private equity debacle.

Of course we have bright points like bank profits, right? Wrong. The only reason that banks are recording a profit is that during the credit crisis they were allowed to stop marking debt to market. The major banks are all sitting on a ton of future losses that are not properly accounted for. But since their unrealistic accounting recorded a profit, they are paying themselves enough money that the bankers (if not their employers) will ride out the coming crises.

I could say more but I'll stop. I'm depressing myself.
Nobody seems to be able to explain the window controls, so hopefully we can be loud enough to get them to switch them back. Everyone should write/harass important people at Canonical regarding this.

I really seriously doubt they have anything approaching sufficient data for the change. It breaks every convention a user would be familiar with (though the controls are on the left like in OS X, the functionality of the buttons is reversed; in OS X, leftmost closes, here, rightmost closes), including existing Ubuntu users.

Commence pressure on Canonical promptly.
This too will pass.

On the other hand, for certain groups the last thirty to forty years have been a long, slow slide from the top of the economic heap to the bottom. Specifically, conditions for white men without college degrees have gone from great to exceedingly poor. It's had an enormous, perhaps defining impact on modern politics, and will continue to be one of the most important influences in the future.

Ask HN: Would you pay for it- Business Book Summaries?
I've been reading a ton of business books lately and summarizing them just to take notes. I therefore thought it would be useful to do this on a more consistent level like 5 a week and put them online for a monthly fee (9.99 unlimited access). My thought is: this would be useful to people who want to get the main points of a lot of books but don't have the time to read them all. For the really interesting ones: they'll then go and read the whole thing.

Consider this a super minimum viable product.
A lot of YC companies do help international workers to get their H1Bs. I don't know what is the exact number.

OP: Anyway, if you are canadian, it will be easier. There is a special category for canadian who wants to work in US. H1B is tricky. And, it has a quota.

Ask HN: How to deal with the C10K problem with a simple script?
I was asked by a client to setup a survey site for Japanese mobile phones that would be displayed at a major event that would be taking place at the Tokyo Dome. The problem is that I'll be dealing with 10k users connecting to the site at the same time, and that the site will only be up for a day.

The client says that he wants no connections dropped, and to prepare the infrastructure so that it can handle it. (My initial idea was to try to find a web service to handle it, but even the best could only deal with something like 150-200 simultaneous connections.)

My idea is to setup an Amazon EC2 instance with nginx or Lighttpd and to make a simple Ruby or PHP script to handle the form that is submitted, and store the submissions to the Amazon SimpleDB.

Unfortunately, I've never dealt with scaling and load balancing for something like this, and I can't find any information about the kind of load I am looking at. Can anyone offer any advice on how to handle scaling with EC2 or any other cloud service?
My initial reaction to your comment is that specifically, conditions for white women with college degrees have gone from exceedingly poor to not too bad.

Just saying.
What's this "print" you mention?
Google also sell search as a product - Enterprises can buy "google black boxes" that index their corporate network and make it easier to find stuff (supposedly... I haven't seen one at work yet, but the bar is pretty low, considering how shitty most enterprise search engines are).
Sounds like a business plan!

What effort would that entail?

Most manufacturers have an option buried somewhere deep in their websites to allow you to order computers at least without an OS preinstalled. Some offer Linux pre-installed; if you don't like the distro that comes on it, no bother, just install your favorite.

You might consider supporting system76. They sell computers with Ubuntu pre-loaded.
The OPT is actually a very good option since you can get it on your own without the support/sponsorization of a company (which is required for an H1-B visa).

All you need is a student visa and having graduated from a US institution in a program longer than 12 months. The fee is only 340$, which is around 10 times lower than an H1-B.

Once you have it, any company can hire you as they would an American citizen or green card holder. 12 months, should be long enough to prove your value to the company/startup so they apply for a green card.

Here is more information on it: http://www.uscis.gov/files/article/OPT_4Apr08.pdf

On top of all that, you're exempt from paying social security and medicare taxes (be sure to notify your employer since some of them are unaware of that fact).
The Economist ran a cover story on precisely this phenomenon a few weeks back:

I disagree. Apple has a quality OS that forces users to use the left-hand buttons, and Ubuntu's perfectly free to try the same thing. In my opinion, buttons should be placed on the left of the menu bar. I've seen that users tend to keep their windows to the left of the screen, and left-side controls may require less mouse movement on average to reach, whereas the right side's edge is dependent on the window size.

I also sort of like the close button on the right with the buttons on the left edge (reverse of OSX as you noted). I think that makes it slightly more difficult to accidentally close the window.

There are some interesting optimization methods that probably wouldn't have been made public if it weren't for patents.

I think the core of the problem that the OP is experiencing is that most API's are really bad. By bad, I mean the API gets in your face and becomes more hindrance than help. I say, choose your API's wisely, find what helps you and discard the rest.

There's still a good chance that you're right, but that chance is much smaller than it would've been had you said the same thing in the 80's.
Yes, it has. When this article first came round I read it all because it was interesting but it's certainly way above the median length of articles that do well here (and above the median of most online content, I'd argue). I'd certainly bill it as being "rather long," though wouldn't go as far as "extremely."
That link crashes my Firefox for some reason. Anyone else having the same problem?
Fair enough. I'd delete the comment if I could.

I apologize, Daniel. That was uncalled-for.
> Incidentally, it's very, very rare that using an unlawfully acquired name isn't related to a serious crime.

I can see how claiming to be someone else who actually exists might be "often criminal", but that's not the only type of name deception.

For example, I know lots of people who sign the equivalent of Mickey Mouse. What serious crime is that related to?

Or, as the Wikipedians say, citation needed.
Of course to do that you have to live in ATL. And work for BOA.

Conditions for almost everyone who's not a working-class white man have improved. But it doesn't change the fact that there is a large group of people who have done very poorly and tend to vote for people who pander to their grievances. The fact that the economic crisis made things markedly worse for these people doesn't bode well for politics in the next few years, if history is any guide.
I read somewhere that cybercrime is extremely specialized; there are people who collect credit card numbers, people who broker them, people who extract money from them, people who launder that money, etc.

Which is my point. The perception of "really bad times" is at least somewhat driven by the fact that a few older white males perceive that their cohort is doomed.
The point of the article is more that an entire generation is going to be scarred by this recession. The author cites research showing that people who enter the workforce during a recession never catch up the lost wages. They always lag behind their more fortunate peers.
I'd love to see the ideas generated by a Y Combinator RFS for harnessing millions of unemployed/underemployed workers.

Amazon Mechanical Turk is one part of the picture, and it opens up the door to more. Anything that makes it cheaper to create work, hire employees/freelancers, or find jobs is valuable in this economy. Or ways for people to earn money besides the mainstream labor economy. Or something that can generate value from activities that people do with their idle time while they're unemployed - whether it's constructive like Wikipedia or entertaining like Farmville.

Gruber, almost alone in a sea of reporting, manages to mention Apple's action here may be related to Nokia's patent suit against Apple.

So rewind a bit, to put this in context:

- Apple accuses HTC of iPhone tech theft (2 March 2010)

- Kodak prompts ITC to consider iPhone ban (18 February 2010)

- Motorola seeks ban on US BlackBerries (26 January 2010)

- Nokia sues Apple, says iPhone infringes ten patents (22 October 2009)

One test for patents' validity is whether the company is enforcing them. With Kodak, Sony, Nokia, Motorola, RIM, and others suing one another as a business-as-usual step in licensing negotiations, the value of Apple's defensive patent portfolio at the licensing negotiation table depends in part on Apple's perceived willingness to stand behind the validity of their portfolio and enforce their patents.

I'd suppose this is a signal to the marketplace not that competitors should create their own original technology, but that if they want to copy, they should license or trade.
