i like the idea, i like how it's made.

But i do not like that i need facebook. why people keep using facebook for logins?
Also the background it's nice and funny but it's a bit "heavy" for the eyes. i think a smooth background and some other small changes can make it look better!
I think you can do two things :-
1) Incorporate the company, and sponsor a part-time H1B using it. You can have two H1Bs active at the same time, but only one can be full time. This way you will be able to keep your day job. You will need to pay yourself salary, and pay taxes to uncle sam.

2) Sponsor a full time H1B with your own company. You will need to quit your day job for this. But its possible. Salary requirement is more strict for full time position.

IANAL. This is based on my research from a few years ago.
On H1B you can't own a company.

You must be an employee of your H1B sponsored company.
You are correct that the Project Euler approach isn't well suited for learning to program, although I would qualify it with "for some", if not most - especially the less mathematically inclined, or those who care more about things like social or real-world problems. You have to show programming and computer science as being more than just solving artificial puzzles or doing math & logic for its own sake.

It should be noted that this site and others have been around for 10 years, and in the meantime the number of people majoring in computer science has actually dropped (I think it finally turned upward this year though), and the proportion of female and minority students in computer science has actually dropped. Notice too how the author of this article, the author of the project euler site, and, from what I can tell, everyone here is a guy. Every article I read about 'why johnny can't program' and so forth are by guys, usually older folks who already understand the relevance of programming, but perhaps can't understand how it might not be so evident to others. I know it took me a long time (almost ten years) to see it. When I was first introduced to programming, to draw an American flag on the screen in BASIC, it was boring and pointless compared to the colecovision next to it :) It wasn't until I created a CGI perl app for letter-writing with our amnesty international group and also a hypercard program for an HCI class that I dived in.

Teaching programming or computer science 'for its own sake' is not going to help most see the relevance of it to their lives and to the world. Show how you can accomplish things with programming, how you can help people, and so forth. Like someone else pointed out, the rosettacode site is similar, but at least it gives some more practical problems.

Also, there's the fact that computer science is not required in most schools, and thus, like engineering, most don't ever think to major in it or work in the field.
Disagree - the catalog business model was a proven quantity going back a century or more, e.g. Sears. Amazon was the first mover and was focused on building footprint pretty much from the beginning. Despite this critical article, a more accurate survey of that era's business press would give the impression that Amazon.com was the "good one" compared to the Outpost.com like pump-n-dumps that were often nothing more than a few webservers. Maybe Amazon didn't get serious until the lean times, but the press hype was generally correct.

On the other hand, the Groupon business model has always been borderline. (I remember my parents buying these coupon books with deals like half-off steak dinner on Tuesdays before 8PM. How many of those companies are still around?) Furthermore, its been tried before on the Internet, although never at this scale. Nobody's quite said it, but it really does seem like the underlying idea is "Facebook has created The New Economy! What possibly could go wrong?"
I prefer the C++ solution as well because detailed control of everything is what I use C++ for, but saying there is no extra complexity "you just need the ..." is funny because you could say the same about everything that's causing extra complexity.

Also, the requirement to add an empty parameter list whenever there's something between [] and {} amounts to extra complexity. This seems to be a purely syntactical dismbiguation thing as neither the mutable qualifier nor the return type should be related to an empty parameter list.

We have to realise what complexity is. Part of it is having to think of B whenver we do A even though we do not wish to say anything about B at all.

Facebook usually just gives the sites extra data and it makes it easier for people who just want one click sign in (at least I think that's why most people do it) but I agree with duiker101 in that you should offer an alternative.

Also the footer bar isn't at the bottom of the page on my resolution so should be fixed.
Beautifully-written article - wouldn't usually spend half an hour reading about construction engineering but the article really drew me in.
OMFG HN fail at understanding what a Ponzi scheme is. Enough.
As far as I understood the article, using references is a desaster waiting to happen as accessing the references once the original variables are out of scope is "undefined behaviour" - probably accessing random values on the stack if your reference was pointing to a variable on the stack
If there's one thing I've learned from studying programming languages, it's that human minds are extremely diverse, especially when it comes to designing notations.

For some programmers, their 'executable pseudocode' language is Haskell, or Forth, or maybe even the assembly language of some specific piece of hardware. Some people might naturally think in COBOL.

Also, the problem domain can dictate some of the shape of the language: Something that's built out of a mathematical expression is almost always going to be expressed most compactly as that expression in standard mathematical notation, with something like APL coming close to being the 'executable pseudocode' form of that program. That said, there are almost always many ways to solve the same problem.

What follows is hearsay but it might give you an idea of where you stand.

Some co-founders in the latest YC batch are on H1B. I do not know how this can be done but maybe you could look through a list of founders, locate the non-Americans and ask them (by guessing their email, maybe?).

You cannot start a LLC in the US all by yourself, but that should not be a problem if your co-founder is American. He can start it. I've heard that your startup cannot sponsor your H1B visa unless it can be shown that you can be fired, which is not possible unless you give away a lot of equity.

I've heard of someone who was on H1B, attended Startup School, walked around trying to talk people into sponsoring his visa so that he can start his startup, and finally got someone to do it. I'm on H1B and just started sending out feelers.

Good luck!

Bad Project
That interview with the LivingSocial CEO[1] was excellent. I think their idea of the local restaurant marketplace will do very well. That idea really makes sense to me, in a way that groupon doesn't.

Maybe you should consider that this is an interview that was turned into a first person essay. So it is very possible that the follow up question to his note taking was " what pen do you use?"
There's been lots of cool tools recently - unix in a abrowser and the like. Does anyone know of a z80- or 6502-in-a-browser?

It should be easier to do machine code programming in a browser sandbox, because the sandbox could give you tools for viewing memory.
It's called "availability bias", because certain examples are more 'available' than others.

Anyone looking for an intern??
I'm a senior in computer science at Oregon State University. I'm looking for a internship to improve my skills and also bring my creative, outside the box thinking to a fast growing company. I enjoy linux development and probably know more languages then C3PO. I'm a hard worker and im looking for the opportunity to prove myself to the software world.

Thank you,

Legally, you can be a co-founder of a company while you are on H1-B. But, you can not participate in business activities and you can not take salary.

You can get H1-B visa sponsored by your own company. Manu Kumar of K9 Ventures was able to do this, read http://k9ventures.com/blog/2009/09/24/my-story-and-support-f...

It should be easier for you with a US citizen co-founder.
This seems like a possibility, and definitely better than giving up altogether :)

Hiring mathematicians?
I'm a pure mathematician who is currently working at a educational technology company. I love what we make and I believe it's the best. We actually have nine million customers around the world, so someone agrees with me.

I've been here for nine months and I've learned more about business and industry than I could have ever imagined. I'm lucky to work with excellent people.

Nonetheless, my work is not intellectually challenging. I'm not used to checking out at 5:00pm, and I'm also used to much harder problems -- the types that I can't help but obsess over.

I want to work on something that's interesting -- something I can work on nonstop. I can find my way around any platform, but I'm certainly not a software developer.

Anyone hiring someone like myself? I'm looking for a challenge, excellent people, extreme dedication, and something amazing.
scan is similar to fold - except instead of the result being the final value, it's a list of all the intermediate values up to the final one (if it exists - scanl is productive and can handle infinite lists just fine).

So the first fibonacci number is 1 (we're concatenating it onto the front of the list), the second fibonacci number is also one (the second argument to scan), and every fibonacci number after that is the sum of the previous number (scan's running total) and the one before that.

I could definitely relate to the whole "let me start with a 1500 page tome". I also tried my luck with a Visual C++ brick about 10 years ago, that worked out exactly as described in the article. To some extent I don't feel those books were ever meant for total beginners.

Some quotes relevant to the questions you asked:

To ensure that the “control group” to which the Habsburg “treatment group” is compared does not include locations that had actually also been exposed to the Habsburg treatment at some time, throughout the definition of the Habsburg variable H is an indicator of whether a location has ever been part of the Habsburg Empire. By contrast, defining the Habsburg variable by Habsburg affiliation at any particular point in time would mean that part of the “control group” had also received a “Habsburg treatment” at some point in history. For example, defining the Habsburg treatment by its borders just before its demise in 1918 would mean that several regions that had been part of Habsburg until 1908 would constitute a substantial part of the control group in the border sample. However, as one robustness analysis below, we show that results are robust in a specification that restricts the analysis to locations that were part of the Habsburg Empire in 1900 (and their control locations) while dropping all locations from the analysis that had been part of the Habsburg Empire at some time but were no longer in 1900.

The specification of our basic model assumes that the Habsburg treatment effect is independent of the duration of treatment. To test for the validity of this assumption, we will also estimate models that allow the Habsburg effect to differ by length of a community’s affiliation with the Habsburg Empire: […]

— Empirical Model, p. 13

Third, and most importantly, in contrast to the basic assumption of a regression discontinuity design, there are a number of reasons to expect some sort of diffusion to and interdependence between neighboring towns across the former Habsburg border. Such reasons include migration and marriage between neighboring towns; local spillovers whereby inhabitants of an Ottoman town just across the border observe that well-functioning public services may have positive consequences, so that they may imitate them to some extent; “frontier” effects in that authorities may behave differently if located close to the enemy, such as when a Habsburg local authority may behave more authoritarian if the Ottomans are next door; and political competition across neighboring locations. All of these effects would mean that the Habsburg status of one town may affect outcomes in towns that are located directly on the other side of the border. Note that any of such diffusion or interaction effects work against our identification strategy finding a significant difference between Habsburg and non-Habsburg locations in the border sample.

— Empirical Model, p. 15

(There is also some relevant discussion with regard to your questions in the Results section.)

Note that all of the things you mentioned would have made it less likely to find an effect.

This looks like solid work. Like always (especially when social sciences are involved), there are problematic aspects to it. Social science is damn hard to get right.

If you're willing to talk publicly, I'd be interested in hearing more about your key scoping design.
I'm sorry, I wouldn't know where to find a good writer. But yes, something like that seems sensible.
Yeah, that's illegal. But let's look at what you could do instead.

I believe you can co-own an American company as a "normal" foreign citizen and be in the US from time to time for a couple of weeks, as long as you go home to your resident country in between. I know some business people who actually do that, jetting back and forth between two or three countries where they are involved. It's a pretty interesting lifestyle, too, as long as you can afford the plane tickets and (at least) two separate homes.

I would prob argue that Groupon as a company is neither. However, their fund-raising model is clearly a pyramid scheme where early and mid investors are 'banking' not on the business model itself paying out but ONLY on the fact that they will be able to dump their share as part of an IPO.

Who here really thinks any of the 1 billion investors in the last round are looking at 'holding on through thick and thin'?

Ask HN: Why not to ask questions from the Groupon early investors
If investors like Buffet, Soros, Faber sell or buy big stakes in some companies then they very often explain their decisions, also they explain what companies and industries they suggest or do not suggest to invest in,

so I was trying to ask from the early Groupon investor Jason Fried why he cashed out on Groupon on HN , there was no answer and people started to label me of "being like a tabloid journalist" , that "its Jasons business only" , "he may have needed liquidity" etc. ( so total liquidity need of early investors was around 1 billion then? )

http://news.ycombinator.com/item?id=2617160

Not sure that it is a tabloid journalism - because Wall Street Journal also lists 3 main reasons why to worry about Groupon shares -

and one of the reasons is that the early investors have taken out nearly 1 billion dollars already ( thats right - 1 billion with a b )

http://blogs.wsj.com/deals/2011/06/03/groupon-ipo-3-reasons-to-worry/?KEYWORDS=groupon+ipo

So - how high is the probability that this may indicate that some average investors who are not very informed about internet business - may get fooled pretty soon ?

And if the average Joe is meant to get fooled by Groupon shares soon - then it may be bad for the whole internet industry ...

so - it seems like a critical question to ask - why so many early investors cashed out on groupon

what makes one to worry is also the fact that the IPO was organized by Goldman Sachs
