No offence to Twitter, but this is a seriously bad way of hiring developers. What are you trying to recruit mathematics scholars as developers? When will companies like Twitter learn not all great developers are math geniuses? I didn't even get a college education to get where I am, I failed maths in school as well, but I can code, so what does that mean? I think it means nothing in the greater scheme of things. By the sounds of it the author got a better position in the end, I'd rather be working at Amazon who are solving much better problems than Twitter ever will likely solve anyway.

If a company (no matter how great they were) tried asking me these kinds of questions, I would immediately stop the interview and thank them for the opportunity.
That's the great thing about something like the pogo shown in the op though (except built into the device). It's entirely backward compatible, so they could include a set of headphones that connect directly, as well as the adapter that lets you use a standard 3.5mm jack.
US indeed has done a lot of bad shit, but I hold a leaders and formative agents of their own country to higher standards. Sure one can blame the US but what were their own leaders thinking when they consciously decided, this is the trajectory that is going to be helpful for the country.

And this to your other comment on this thread, I admire your will to engage in a dialogue. I have become much too jaded. Its as if people have become rigid and unquestioning of the history they want to believe in. Google Sunderlal report you I think will find it interesting.
Do software engineers need adult day care?
What with keyboard loggers, unsecured wifi, video cameras, stolen computers, stolen iPhones (with email access, now you're vulnerable to password resets), there are just too many attack vectors for even a 16 character password to suffice. You need to be protected by both something you have and something you know. (My iPhone has a 16+ character password. It's a pain. It's worth it.)

Is there a definition of ah-ha moment? Seems like what strikes one person as an "ah-ha" insight might be a baseline assumption of another person's thought process.
Maybe if you had had Dropbox vs iCloud choice, Apple had not rejected it.
Maybe I'm just not used to this visualization, but I didn't find it particularly easy to see the thing it was intended to show: which countries are over- or under-represented in Wikipedia coverage, relative to their size. It seems like this could have been conveyed just as well by a table listing the population and size, sorted by some normalized ratio of those. I don't see how knowing the geographical position, shape, and absolute size of the countries, as conveyed by the map, actually helps demonstrate the point.

I've been using bing as an experiment for the last three weeks or so. Google is far better for academic searches, and better support for math rendering would help extend the lead in that category. Isn't that reason enough?
I noticed that angular momentum seems to be an unconserved quantity as well. I would not want to be an astronaut in the universe simulated here!
> The point is why do we need something specific for math.

You seem not to have been around when we had to do it over plain text. It sucked. MathML is a huge gain for sharing thoughts over scientific matters. Of course, they aren't as important to today's "open web" compared to, say, ads and making text rumble with JS, but they shouldn't be relegated to an entirely unimportant position, especially considered they're part of the famous HTML5 standard that should supposedly deliver us from the dreaded fractures between platforms.
This is a great idea (even if not original). Every news agency should budget one of these as part of being in the business.
> Is there a definition of ah-ha moment?

Not an exact definition, no. But if a question is exceedingly simple after one tiny bit of insight that doesn't require much analytical thinking to arrive at, that certainly falls into the category.

So glad Twitter is continuing the tradition of useless interview questions.
It means (I think) that the trough between the "good answer" and the "bad answer" is too big. So basically either you know it or not and can't "grow" toward a solution easily

I hate this kind of problems.

That seems to be part of the program for vendors like Ford, where the employee asks the customer to call them if there is anything that they can't rate perfectly so they can fix the issue for them. They use the survey as a way of flushing out issues that the customer wouldn't otherwise voice so they can deal with them. It's less about collecting stats, and more about having an extra tool to get the customer to happy.

Well, you may want to hire math scholars. I think it's important to have some in your team.

But it's also important to focus on other aspects as well.

Either way someone suffers, kind of a silly dichotomy. Especially when modern android smartphones, let alone tablets, have 2GB of RAM.

Also, Apple has the power to mandate that all apps have to run well on whatever old hardware Apple wants to keep supported. There's no good excuse.
>I don't know where your preference comes from but I would love to see the planets get converted into giant computers and minds. We should optimize the universe for our values, rather than preserving the random state it was put in by nature.

Congratulations! You're the first person outside /r/hpmor to make my Chemical Shed List for Irresponsibly-Applied Phlebotinum! When shit gets real, I will take you out behind the chemical sheds and shoot you.

People like the so-called random state things were put in by nature. Saturn, for instance, is pretty the way it is. Hell, think about it this way: what if I suggested that your house you actually live in is simply suboptimal as a house, and should instead be converted into a huge brain I can use for thinking? After all, it's just another step in my optimizing the universe for my values, which apparently include adolescent dick-waving and solving lots of math problems rather than a human civilization with people to talk to.

Well, you shouldn't want to do that, because after all, you need a place to live. More broadly, even if you've "gone virtual" (as you indicate some desire to do in occasional hard-SF threads), you're still a human being, and you're supposed to have sentimental attachments. Sentimental attachments are, after all, what make us human in the first place.

This whole "planet-sized X" thing, for all X other than planets, is basically just another adolescent power fantasy. Consider that if Ultimate Power, or some semblance thereof, seems to be your goal in life, there may in fact be something wrong with you. I can't actually think of anything a human being wants other than raw power that is served by wrecking entire planets.

Real life is not a scifi novel, not even the finer grade of scifi novel.

>"Extelligence" doesn't really explain much. Sure a mind on it's own might not accomplish much, but we still have to explain what it is about human minds that allow them to think and learn in the first place. Can apes be taught language? If they were would they gain higher level intelligence or does it take more than that? I bet it isn't that simple.

Actually, gorillas have been taught simple sign-language before and can form coherent sentences. Chimpanzees have been observed learning and passing down more advanced tool-using skills than we thought they were capable of. Human children, raised without exposure to language and culture, don't naturally turn out as civilized "human beings" of the kind we expect to meet.

The Big Secret is culture.
really hate the Taleo systems and such. They are made stupid on purpose.
That is arguable, we have the freezing people but going. Sure it is being done in a very destructive way to the human body, it is a bet though that at some point in the distant future technology will get good enough that the current freezing method could be reversed.

> The next day I showed this question to my TA, who's a PhD student in theoretical computer science. After 40 minutes he was also stuck with nothing.

That just doesn't speak well of this particular PhD. The one-pass solution is rather obvious. I hate puzzle-based interviews with passion, but this is actually a very reasonable question and it does help to tell apart people with "theoretical" computer science skills from those with a bit more practical experience.

As a relative newcomer (who didn't downvote) I can tell you that HN is a massive echo chamber.... That is the polite word for circlejerk.

Opinions here are often heavily biased and the groupthink causes them to be self-reinforcing. In a world of serial entrepreneurs we've come to the oft-touted idea that "execution trumps ideas." Along the way that got perverted, and now people think you don't need to build something in demand. If your Execution is done well, a market will materialize. As a result the culture here is at times a hipster culture: the Old is denigrated while the New is idolized.

it's not "more than one puddle"; it's that i don't count the second puddle because i don't ever "close" it by encountering it's level again. if i go off the edge, i should close it as best i can.
I had two phone screenings with Amazon recently and they decided not to continue with my application.

It was depressing to me and I felt down for quite a bit, mainly because on the second phone screening I just couldn't do the coding task asked. My mind went blank and I probably sounded like a 5 year old struggling through the simplest of questions.

It's my own fault though, I just got more and more stressed over the preceding weeks reading algorithms textbooks and "CareerCup" tests I think I just burned out.

I totally understand that top companies like Amazon and Google can afford to be ruthless and choosy in their interview process, after all, they're top companies for a reason, but I guess it just wasn't for me
Google exists to advertise. Academics are woefully underpaid. Who wants to advertise to a bunch of broke intellectuals that are just going to ignore your ads anyways?
I have no idea why a bunch of people here keep saying these questions are good for recruiting 'mathematics scholars'. Fact: I am a mathematics graduate student and I would not be able to solve this problem. I hope there isn't a notion that people studying mathematics spend all their time solving Project Euler type questions.

In fact I would be thrilled if they are recruiting for math people. They are not. I have been in the job market for a while now and recruiters literally stop listening when they don't hear "CS" in the first sentence.

No, it doesn't involve the "a-ha" moment.

Two-pass solution is obvious, just look at the final state. Once you are at that, the one-pass is a run-of-the-mill optimization of switching from accumulating and then processing the state to doing it all in parallel. The ability to recognize when this is doable is a good way to tell someone who's done it before (in some other context) from those who merely wrote a functional prototype of Tic-Tac-Toe in TurboPascal.
Is it really a tough decision? A tough decision would be to put soldiers on the ground to do that. Killing someone in a far away country with very few chances that it will be reported looks like a rather easy solution.
Ask HN: How does your CV look like?
I've happened to see dozens of CV's that don't follow the traditional standard of a plain Word document with some text in it.
How does yours look? What part of it makes your soon to be employer say "Wow, this is the one"? Have you used unconventional handing out techniques to highlight yourself?

If you don't feel comfortable with personal info, hide it, as this is not intended to be a recruiting topic.
It's not you, it's them. A rather brilliant acquaintance of mine did the whole fly-to-SF song and dance with them and didn't make the cut either. (He got snagged by a wonderful startup soon after though.)

What is important to understand here is that these processes are highly variable and there is an element of luck involved. It's just the nature of a human-driven process and a complicated organization.
You know, in the end, the "spec" is what is actually used.
> I stopped reviewing for Vine after a short while. Since I couldn't give or throw the stuff they sent me, I imagined me drowning in a pile of terrible, misspelt books after going deaf by rubbish earphones. I actually don't know how I got to be a Vine reviewer in the first place. I didn't have that many reviews (less than 10 when I started, if I remember correctly). Anyway, to begin with it felt like a honour (and a chance to bag free goodies) and at the end it was a chore (and discussions with myself whether it's moral to throw the stuff away) and I stopped.

This is my biggest problem with the program - the not being able to sell/chuck/return items they've sent. I don't have permanent room for a spin bike or a multifunction laser printer. There should be some way to keep the stuff you like and return the stuff you don't. Honestly I would not be surprised if some Vine reviewers ended up selling stuff.

Has Amazon actually asked people for anything back?
What made you say that twitter is trying to recruit math genius? The author's solution involves calculus while the intended solution is only a loop and some if statements. I actually like interview problems like that. It requires critical thinking which shows how the candidates think and it is also almost impossible to google.
Definitely agree. As a problem, this is pretty easy. Ask anyone that does competitive algorithmic programming. The linear solution is obvious, I wouldn't say that it requires a eureka moment, even though I didn't bother thinking of the one pass because the difference would be minimal at best (for most inputs.) OP should share what his internship was about, I'd disagree if it had more to do with understanding practical implementation and development than efficency and algorithms. Both are valid skillsets equally useful to twitter.

I grew up in a coastal city (Miami) and watched prices climb 100k, then bolted to 500k-600k before settling back into 100k-200k again. Houses were always in demand but prices were constrained by average salary (35k avg) until investors got involved and banks took the constraints off mortgage requirements.

I watched a friend put her college graduation money as down payment on a 4 bedroom house and struggle (she couldn't afford to go out, couldn't even afford to eat meat) for a few years all in the vain belief that it was an investment. She aged about 10 years in that period time.

I've been a FF enthusiast for years now. Don't never really use chrome at all anymore (although I do use torch browser for downloading and site unblocking). I find that for standard browsing, nothing works better and quicker than Mozilla.
Wait. I fail to understand why this counts as a reason for rejection. You attempted a solution, which the interviewer backed up (I assume if you were heading in a completely incorrect direction, he would have told you that), you showed quick thinking (connecting local maximas to the problem) as well as coding competence and basic testing knowledge.

Is this not what Twitter desires through its interviews?Because time and again I have heard that companies look and focus on people's thought processes more than their exact results.

PS: I'm a college student so I'm really keen to know how important being 100% accurate is.

Ah, right. Now that I actually read your code, that's the real bug :p

The issue with this "state machine" approach is you don't have "lookahead".

In the two pass approach (approach from one side, then the other), you essentially have two machines, one implicitly serving as the "lookahead" for the other.

thanks! i updated the gist (https://gist.github.com/igor47/7228586/revisions), but the solution is not nearly as simple as before.
and there are very many arguments pro MathML in it as well, which makes the reasoning seem not so well founded.

to quote one rebuttal of every point the thread op made:

1.1. you make a point against adding unnecessary typography. Mathematics is text, but adding new requirements. It's comparable to the introduction of RTL or tables much more than musical notation. It's also something that all school children will encounter for 9-12 years. IMHO, this makes it necessary to implement mathematical typesetting functionality.

1.2 you claimed MathML is inferior to TeX. I've tried to point out that that's not the case as most scientific and educational publishers use it extensively.

1.2.1 you claimed TeX is the universal standard. I've tried to point out only research mathematicians use it as a standard. Almost most mathematics happens outside that group.

1.2.2 You pointed out that MathML isn't friendly to manual input. That's true but HTML isn't very friendly either, nor is SVG.

1.2.3 You argued TeX is superior for accessibility. I've pointed out that that's not the case given the current technology landscape.

2 You wrote now is the time to drop MathML. I've tried to point out that now -- as web and ebook standard -- is the time to support it, especially when your implementation is almost complete and you're looking to carve a niche out of the mobile and mobile OS market, ebooks etc.

2.1 you claim MathML never saw traction outside of Firefox. I tried to point out that MathML has huge traction in publishing and the educational sector, even if it wasn't visible on the web until MathJax came along. Google wants MathML support (they just don't trust the current code) while Apple has happily advertised with the MathML they got for free. Microsoft indeed remains a mystery.

2.2 you claim MathJax does a great job -- ok, I'm not going to argue ;) -- while browsers don't. But we've used native output on Firefox before MathJax 2.0 and plan to do it again soon -- it is well implemented and can provide the same quality of typesetting.

3. Well, I'm not sure what to say to those. If math is a basic typographical need, then the syntax doesn't matter -- we need to see it implemented and its bottom up layout process clashes with CSS's top down process. No change in syntax will resolve that.
