"how the hell could these same people who fail fizzbuzz write production code in previous companies?"

Maybe they had a lot of supervision, or were someone that could talk a good game to management but didn't deliver, or maybe they just fiddled around with minor stuff in other folks' code.

While experience is obviously a really good thing and a useful thing, if they can't write fizzbuzz you'd have to re-evaluate that experience in the light of new knowledge.
> Which page were you on, the front page of the website doesn't say that to me?

It's the contents of the <title> tag so it displays on the title bar of the browser you are using to read it with and in the tab if you are using a browser with tabs.
Yes, but those who can't could cheat by studying it, and with everybody talking about it...
I need to catch up on my quantum physics, every time I read that someone pulled off quantum teleportation I'm disappointed when I read the line "here we realize quantum teleportation between two remote atomic-ensemble quantum memory nodes, each composed of 100 million rubidium atoms and connected by a 150-meter optical fiber" taken from the source article. http://arxiv.org/abs/1211.2892

I know there's a difference between what they did and regular fiber optics. It just doesn't seem to be quite the same. Can it be done without the interconnecting material? If not it's really useless. When I picture practical uses of quantum teleportation I picture things like rovers instantly sending data and receiving instructions.

Yip. I wonder if it makes more sense to focus on bd (for hn, this was building the YC brand) once you reach some measure of product market fit... Very interesting observation.
I'm better at all three of these things than my counter parts with degrees, who for the most part are totally clueless on these topics.
Yeah, at first I thought, that's impressive that they can catch up so far, even if they fall back again. But then I thought about how much further ahead Firefox and Chrome would be if they'd effectively abandoned their users a couple of years ago and hid in some research lab to plan the next big version. That's a whole lot less testing, bug-fixing, releasing and reworking etc.
Visualizing Adjacency Matrices in Python
Dude, spinneret makes the same goddamn mistake.

I don't want my HTML templates in my Common Lisp code!

Most of my projects have a separate frontend guy who needs to be able to write the templates himself without touching or knowing the backend code. Django, Rails, Flask, Sinatra et al understand and respect this.

For some reason, most Clojure and Common Lisp libraries fail to grok this. I don't know why.

I want plain HTML files with some simple (mustache or Django/Jinja-style) tokens for injecting data provided by a hash-map/dictionary/assoc-list.

That's. It.
I'm really excited about our massively parallel future, not least because I have to run scientific code that would greatly benefit from it. But at the moment it's so hard to program for this sort of thing: can someone explain why, in simple terms, something like OpenCL or CUDA is so damn complicated? Is there any way to avoid having to have a low-level understanding of how a GPU or co-processor works, rather than expecting the vendor to implement an easier to use solution? I'm thinking about, e.g., Matlab's "parfor" (parallel for) command, which is super easy to use.

The article states that "All of these [CUDA/OpenCL] problems go away with the Phi. It's a pure x86 programming model that everyone is used to. It's a question of reusing, rather than rewriting, code" but I find it hard to believe I can just drop existing code into it and expect decent performance.

Founder Releases Report Detailing Why His Startup Failed
As they're serving that <body> they could easily serve a "this link has expired, view the new front page" with a link to the homepage and possibly a list of other top pages (like "new" or whatever).

Even if it's not going to be fixed then it could still be improved with, it seems, almost no work.

Mind you I've seen offers to fix it for free (requiring someone the owners trust to review the code I guess) that have apparently been rejected so it's presumably a chosen outcome.
Admittedly, my second two statements are largely digressions. But as to the first...

My basis was that the button pusher was critical to your business and automation was not feasible, since you would have done that from the beginning. I don't know which economic concept this describes, but the idea is that you are compensating the button pusher based on their absolute, objective value (no pushing, no profit) rather than subjectively (skill-less "schlep").

God I hope so.

I've tried dropping fundamentals of quantum mechanics on my kids so that it doesn't seem so alien to them. I still have trouble grokking the spooky-action-at-a-distance experiments, but I know what the punchline is.
Even with the 40% hit rate you can reduce it further by asking what could make it perform faster.

"That's great for FizzBuzz to 100, but what if we went to a million? What would you do to make it perform in... I don't know, a quarter of the current execution time?"

Even if they wrote a solution that avoided % or / it is always worth a few minute exploration into how one might optimise code that works today but one day is found to be slower than desired.
Now this is actually a thing I could use Arduino for! Most of the projects I see on Arduino-related sites are cute toys, but not too many useful things.

I, personally, would like to see more of DIY projects describing how to do Wi-Fi or Bluetooth enabled:

- Blood Pressure monitor

- Heart rate monitor

- Weather station with hygrometer and barometer

- Security camera with motion detection

- Mood lamp (or lighting system) with voice recognition

This is a very useful post if you're looking to roll your own Design Structure Matrix (http://www.dsmweb.org/) visualization tool.
So I'll ask the obvious question. Resistance or Enlightenment?
Firstly, citation required. We need to know how rigorous the study was and whether or not it controlled for other factors such as SES.

Given breakfast's popularity in our society, one would expect that many people who don't have breakfast can't have breakfast - and this is highly correlated with socioeconomic status and poverty, and we've known for a long time that SES is a greater determinant of academic performance than just about any other factor.

In other words, are you sure your study isn't just talking about poor kids not having breakfast, or is it properly controlling for variables?

I'm not jumping to any conclusions before I try it. I prefer CL over pretty much any language given the choice. It is a fine tool for making software. Having an in-point to writing native CL code for mobile devices sounds pretty good and not too far off to be too good.
Blame Rovio, Tiny Wings and Whoever makes Wheres My Water etc.

They had hit games, made sequels and therefore had the power to push the market value back up again (even by some small increments) but instead they chose to sell for the smallest amount Apple allows again.
I'm going to go out on a limb here and assume that the primary materials cost for Coke over this time period is sugar.

There are other costs (production, distribution) but over that time period, those were benefiting from decreased cost through industrialization, etc.

This link gives a history of the sugar price (only back until 1912): http://www.tradingeconomics.com/commodity/sugar

Basically, sugar did not increase in price over that time span - except for a dramatic spike around world war I and relatively minor fluctuations.

That spike put Pepsi into bankruptcy, the company was sold at auction, reorganized, and after the great depression started selling a DOUBLE-SIZE (12oz) bottle for ... wait for it... $0.05).

Completely agree. IE10 can't even beat Chrome when it's launching once every 2 years. This means Chrome will simply expand the performance gap during this 2 year period.

Now if only Chrome for Android had version/feature parity with Chrome for desktop, because it's a full 5 versions behind right now - and it shows. It's not even competitive anymore on mobile because of this huge development gap. Google needs to take Chrome for Android as seriously as they take Chrome for desktop, if not more so.

Mozilla can't bring its full browser technology to iOS, Windows Phone, and Windows RT
Does this give other people the willies, or only me? Its scary that 2 of the 3 big players in mobile effectively lock out so much. In so many ways, the mobile wars are much more significant than the browser wars. Having a machine that is completely locked down and only runs 'authorized' software is chilling indeed.

If the interviewer were good, they would play it cool and immediately ask the candidate to walk through the code out-loud and give reasons that they did what they did.
This is how things have been in the physical science fields. Chemistry, biology, you name it--capital intensive.

The computing and theoretical fields (so long as they're non-experimental and require no more than simple simulations) are the exception to the rule rather than the rule itself.

Also, until a space is commoditized, working in it is expensive and time-comsuming.
The kind of person who has heard of FizzBuzz before is someone who cares about their profession and reads about it. They're unlikely to fail the test in the first place.

For it to become common knowledge it would have to be part of a significant percentage of interview screens across the industry. Evidently that hasn't happened, and I wonder if it ever will.
Looks like they are paving the way for a Google Glass world.
I think Mozilla have made a big mistake by not complaining about bundling Safari in iOS devices. It looked jokingly funny when they attacked Microsoft for IE bundling Windows8 RT when they had 0% market share. Now look at the market, Android have almost 70% of market share and iOS took other. So where does Firefox stands now? This situation forced Mozila to write a new mobile OS which I think does not stand a chance against other big contenders. In 3/4 years I think Firefox will be like what Opera is currently right now, small niche market share. I am sadly saying this as die-hard Firefox user. This is what you get when you compromise openness.
My question was: Why would you create a function that does something you could access as a built in language feature ? What is the benefit of using a function as opposed to just evaluating the result of i%3==0 ?

Looking at a function call for "multiple_of_3" I would actually expect it to do more than i%3==0 since that could've been done just right there.

I'm just trying to understand if there are benefits of doing it this way and not directly. So far I've just encountered snarky remarks and no real arguments either way.
You really should proofread or ask someone to proofread your text before publishing something like this, particularly as it purports to impart wisdom. There is misplaced punctuation littered all over the place, as if a bomb exploded amongst your sentences, and it is full of spelling and grammatical errors. Presumably English is not your first language, for which I can make allowances, but I can't take anything with this level of errors and lack of attention to detail seriously. Even just using spaces after punctuation consistently would help a lot.
I use Opera on my netbook (Atom 1.6Ghz, very slow). Chrome is actually faster at rendering or interacting with pages - which is what benchmarks generally measure. What they don't measure is how responsive the browser is. For me, Opera is far faster than Chrome at switching tabs, opening new tabs, having lots of tabs open in the background, having more than one tab loading at once, and eats less of my system resources than Chrome to achieve them.
Yep, it's for unlimited/unrestricted play ... so in this case it's a trial. But a community has in fact grown around this game, and in the future they could enhance it for additional IAP funds, sort of like the dagobah IAP in angry birds starwars. I don't know if they're actually planning to do this particular thing, but he even says that he wants his games to be ongoing services that evolve and improve over time.
apply to enter a university doing research in this area. there you may find a lab you can eventually work with.
As noted in another reply to this question, get them to bring in a project and explain it.

Additionally, they could spend some time with the team they'd be working in, pairing (or whatever) with other members and really demonstrating their abilities.

It's not really that difficult to get away from the whole "technical question at the interview" problem, and I'd wager that in the long-term it'd be better for all concerned.
Hey, just updated the conclusion to clarify. Thanks for the feedback.
Ask HN: Hacking traction for Yoink.com (A free marketplace). What would you do?
Hey HN - I'd love to get your thoughts on how we might be able to gain some traction for our new startup, Yoink (http://yoink.com), launched last month in NYC.

The idea behind Yoink is that it's a trusted place to give and get things for free. Kinda like the free section of craigslist but without the creepers, and like Freecycle but without the multitude of daily emails, no-shows and hassle. We want to create a transparent gifting economy, where people can give and get things, whether it's passing on old furniture, lending a hand to a neighbor, or simply baking some muffins to make a stranger's day.

By launching in NYC, our aim is to start small, iterate & develop the product to meet user's needs - but getting traction is (as with most marketplaces) proving an interesting problem.

So whilst there are a number of interesting things we're working on, and a ton of great resources we're referencing to come up with ideas (some listed below) - I thought it could be fun to open it up for a discussion to see if you had any thoughts on how we might go about tackling this problem and kickstarting things - looking forward to hearing your thoughts! :)

P.S. Some great resources on traction include:

In my book, that's a pass, but you should have a discussion where you walk through the code and ask the interviewee what happens when i is 15, and hopefully they'll spot the problem, maybe with a little bit of nudging.

But the main point of Fizzbuzz is that some people who call themselves programmers are incapable of producing a loop, some conditionals, and some print statements. Your solution had that, which is why you passed it. The point is to find the people who can't even get that part right.
It's scary how much this sounds like the world envisioned by Daniel Suarez in Daemon: http://en.wikipedia.org/wiki/Daemon_(technothriller_series)

Google has diverless cars, Glasses that overlay information on top of reality, and now is making a sort of game out of it.
Thirty years ago, the most advanced multi-million dollar laboratory in the world would not have been able to understand or tinker with the computer you're sat at currently.
"Sorry to be blunt, but make a game with real value - not a casual puzzle game with a limited move energy..."

Have you played Triple Town? You can argue about the ethics of how the developer is making money, but the gameplay is ridiculously solid. Casual or not, it's a genuinely good, original game with a reasonable amount of depth to it.

Brightcove CEO slams Facebook, wants to end platform wars
I'm very familiar with the DoD's byzantine and prehistoric policies. You're absolutely right. And it's ironic, because changing their patch management strategy would provide better security. The DoD is stuck in a compliance world, rather that one in which they manage risk.
Fortunately there are plenty of employers.

Even Google lets you try again in a year.
YES! let's build the matrix! who's in with me?
I can disclose the details privately, the underlying is complicated, but working (with plenty of examples), but the device I'm proposing isn't.
At no point in the article is the password the weakest link. Crappy password reset forms are the weakest link. If we switched to e.g. hardware dongles for security, we would still have this link for "lost my dongle" I don't see how any form of authentication will work so long as companies provide a means around it.
If I were them, they should just get users to use real names and addresses to send e-mail, faxes, and paper mail to the offices of the public utilities commission and to other officials who will pressure them.

Fundamentally, these guys just need to increase social capital with regulators and invest in legal infrastructure. The government is just like another giant company with dependencies and old architecture. Trust me, it's just like investing in weird ERP integration to get access to all of those clients. It's not something that is necessary to the evolution of your product, but it's something you just have to do because the market is just shaped that way.

Also, any press is good press, and once these three get large enough, it'll be widely unpopular to not support them.
Can someone with a greater understanding of quantum physics chime in here - is this correct?
Measurements of CPI during that time point are of more questionable accuracy, CPI measures many different types of goods (not all go up together), and a doubling of CPI over that many years is relatively low inflation. I didn't disagree there was inflation in any of my comments. Further, the article admits at the very end that increasing inflation was ultimately what forced Coke to raise its prices. Doesn't that imply that the lack of high inflation was part of what enabled Coke to maintain low prices initially?

>When I picture practical uses of quantum teleportation I picture things like rovers instantly sending data and receiving instructions.

That won't happen. It's impossible to transmit classical information faster than light via quantum teleportation. You don't necessarily have to have "interconnecting material", but there will always have to be a classical information channel, and that will always be light-speed bound.

This article highlights one really big drawback to 3D capture. When we researched 3D at my former company, we realized that while in the 70s you were able to provide color TV with the backwards compatibility of black-and-white to consumers you can't really do that with 3D and provide 2D and satisfy both classes of consumers.
A good 3D videofeed can stay in the same position for very long shots and allow viewers to wander their glance around and experience the scene. I have shot 3D videos of concerts and you can have a really great viewing experience of seeing an entire song from one front-row position, because it allows you to really capture that same experience and to feel space.
In 2D you must use lots of movement to keep a viewer engaged and you need to use pans to simulate space.
All this results in two separate productions and mixing environments for 2D and 3D if you want to do them both justice... And this is why 3D has so many challenges right now because it is too costly to provide it to what is currently a niche market.
Think of it more as "testing how they don't work." A computer without google ensures that, however they may work, "google it" is not their only method.

I don't want to hire somebody that can only "ship" with google.

Finding truth in the noise of StartUps: Silicon Valley
Viral launch page secrets
I'm the co-founder of a social startup and we're now building out our launch page. When complete, our launch page will contain a composition of imagery and video. Visitors that signing up will get (1) early access to our beta application and (2) the opportunity to claim their username on our platform after referring 5 friends. They will easily be able to share the page with friends via email, Facebook, or twitter.

Have you developed launch pages that have generated significant traffic in a short period of time?

It would help to get some input from others who have developed successful pages. In your response, please tell me the technique(s) you used and how many signups you've receive in what time period. Also, including information about why you think it worked or didn't work would be helpful.

Thanks in advance.
I don't think that quantum mechanics is going to be rudimentary and easy to understand for schoolchildren unless we have some pretty massive overhauls of mathematics education.
Which makes it quite annoying to read.
I'm not a native english speaker but that does not mean that I would write code written in german idioms - not even in the comments...
>> We are irrelevantly small and unimportant

That we are relatively small is undeniable. That we are unimportant is an emotional judgement that I think is unwarranted. Size != importance.

Importance is a value judgement made in a mind. My left thumb is more important to me than Alpha Centauri is. As far as I know, Alpha Centauri has no opinion on the matter.

Are we important to one another? To yet-unknown sentient creatures? To God?

The answers to those questions will probably not depend on whether we are 1 meter or 1 parsec tall.

These comments summarize my thoughts rather eloquently.

Clicked through to the article expecting something interesting, left almost immediately upon realizing it was just Mat Honan milking his hacking once again.
On the surface yes, but Ingress is strategically brilliant on many levels. Well executed, this could make Android the 'cool' OS to have on your phone. This is a great strategy to build the Android brand and sustain their unit volume domination.
Just a continual procession of major security issues, never with a proper response or analysis from them.
...and on all of the Symbian^3 crowd of phones as well. Quite a lifesaver when travelling around Europe and not wanting to get gouged on roaming data charges.
One thing this page noticed that I hadn't previously was the comment // See design doc at http://go/at-teleporter for more information.

I believe that's a Google intranet page, and so this story is left hanging for the non-Googlers among us.
