The best model I can think of for how these might be used is the use of scooters in Asia. In Taiwan, for example, there are bicycle/scooter lanes on major arterials and special signage and traffic rules for scooters. Major intersections have 2-stage turn boxes exclusively for use by scooters and bikes, and there are scooter/bike boxes at the front of most traffic lights. A scooter is the fastest way to get around when there's traffic. The downside is that scooters are still very dangerous, since they still sometimes have to interact with large vehicles. A vehicle even shorter would be even worse.

The article focuses a lot on the energy efficiency of these velomobiles, but I would argue that the time people waste in traffic is a much more pressing problem. Reforming our infrastructure to support smaller vehicles and to give preference to public transit is the solution, and it has the additional advantage of making all kinds of more efficient transportation possible.

I type news.ycombinator.com at the URL prompt, hit Enter. Nothing happens, then in 2 to 10 seconds the URL changes to "Loading.." with a new dot appended every second. And after few more seconds it changes back to the URL input and blinking cursor. The map on top stays exactly the same - white pixel grid of the world on black.

In general I think people are more likely to lie on polls than before, but also have always been more tempted to lie on polls which make them offended or defensive, which age probably does.

I'm curious if the take over 80 set are more likely people in their 30s-50s who find age polls somewhat offensive (or at least the implication), or people under 20, or whatever.

Perceptions of age bias actually interest me more than age distribution on HN.

Except that I, and I'm sure many other people, are interested in more than just performance. I want to know how much code it is to achieve some small subset of usefulness, and what it looks like. Is it overly complex? Is it split apart in a paradigm that doesn't match my mental model very well?

I agree most of us aren't building blogs (I'm not), but I believe a blog is a reasonable stand in for a more complex application. It obviously won't test everything, but the requirements are well understood (or can be well understood, if defined well enough).

Also, who's to say that some of these frameworks aren't going to perform significantly worse when they start having to do more than simply serialize data as JSON across a socket? With that in mind, how accurate are some of these benchmarks if they aren't set up and used how they would be in real life.
It appears my observations were off. Consider my earlier comment recanted (it seems I can't modify/delete it now).
Were you able to get in touch with somebody at Google? If not, Rand Fishkin of SEOMoz has a tip: search for them in Google+. Since Google is making a huge push for it, and since many of Google's employees' bonuses depend on the success of it, a lot of Google employees are on it. Enter your search term, then change to "People and pages" and voila. Good luck.
It's funny, many coders are smart enough to figure out that the solution to an O(n^2) algorithm is typically not more CPU cycles but changing to an O(n*log n) algorithm (or what-have-you). Yet they often refuse to make the same observations when it comes to their own productivity, they just throw more cycles at the same algorithms and expect that to be the optimal solution.
This seems a hollow platitude. Might as well have "Reasons you should write proper software." I mean, there can be little doubt that you should.

Don't get me wrong, I am incredibly sympathetic to the problem. I just have not seen incredible evidence that one can get better software, just because one wrote tests. Same for types. (Which, I realize, can be seen as a form of tests.)

The point I keep flirting with is that learning to write good testable code is just as hard as writing good usable code. One does not prevent the other any more than one causes the other.
It's funny, my neighborhood has a great relationship with a couple local dedicated Agents, we've all been concerned about the housing prices, our tax assessments and even more importantly, the low estimates Zillow keeps showing in our neighborhood (compared with every other source of assessments)...they both agreed that pretty much nobody in the industry in our area even pays attention to Zillow anymore the estimates are so far off the actual value.

edit just checked, my house for example, sits on the same block as two recent home sales, neither one is reflected in Zillow and both sold for far higher than the "Zestimate". The townhouses a few blocks over (which originally sold for about 70% of my home's price and are about half the size) are full of recent sales that are within 10-20% of the "Zestimate". The much smaller single home facing mine is "Zestimated" at a few tens of thousands higher than mine, but sold originally for 80% of my home's price.

It's basically nonsensical.
I'm not sure I disagree with the decision to remove it ... and there's still no proof that all the diagnoses of autism are actually the same disorder (we have a lot of research yet to be undertaken).

On a side note, paging through the DSM can be both amazing and scary. My wife waves it in front of the students in her "Introduction to Psychology" classes just to show how many different types of formal disorders there are. As well as reading selected sections to them. What becomes quickly apparent is that there is no "normal". Everyone has tendencies towards (usually) multiple disorders and it seems (to me ... but I am not a Psychologist) that most of use reign in those tendencies for the benefit of society.

What if you lose your domain?
the same for me
It may suck for people trying to get their start, but experience is a great first indicator. If you find an agent that's been doing it for 20-30 years you have someone who has seen the ups and down of the market. They should have sold lots of houses. Also, see if you can find someone who sells houses in many price ranges. My agent routinely sells expensive (1M+) houses, but works just as hard for me with a budget that is a fraction of that. I asked her about it once and her response was that one day me or one of my friends would hopefully be buying a house in the millions and I would recommend her then. That type of thinking is not only long term, but also shows the dedication to making each client happy.

Hmm. Is it not commutative?
You are mistaken. There IS a version of "forte" that is correctly pronounced "fortay" and that is the musical term for loud, which is Italian.

The correct pronunciation of "forte" as in an area of strength or speciality is "fort". Older dictionaries will give this as the correct pronunciation but more modern and especially online dictionaries sometimes give "fortay" as an alternate pronunciation.
Unfortunately, the problem with freemium is that at the end paying customers have to sponsor the free accounts.

And in most cases providers do as much as possible to lock you in, so you don't switch to a cheaper option when you reach certain size.

On the other hand, we want customers to know that they can leave us whenever they need to. Your apps are completely portable, so there is no reason not to give it a try.
I like the idea greatly, but it appears to be broken at the moment. Perhaps the HN load is too high?

The top reason is indeed Knowing Your Code Works.

Be it because requirements keep changing, new features are added, many people working on the same code, refactoring, whatever... Having good unit and functional tests catch a huge amount of problems that would be hard to find latter.

The other two points are pretty minor in my view.

And the suggestion to improve code coverage is just cheating. There's no excuse for that. Either don't track stupid metrics, don't add unnecessary catches, or properly test exception code.

Too bad this isn't open source, it's the only thing stopping me from using it. Probably gonna use discourse instead
unrelated note:
As an owner and advocate for pitbulls, I think this analogy is inaccurate and perpetuates the stereotype that pitbulls are aggressive animals.

As a result of breeding, pitbulls are wonderful with people, despite their reputation. Even dog fighters would agree as a person generally stands in a dog fighting ring to break up the fight (and doesn't want to be attacked). It takes a great deal of "training" (aka abuse) to make a pitbull aggressive towards people.

Pitbulls are not always the best with other dogs, but it is something that can be remedied with an assertive owner.

tl;dr Pitbulls are loving, sweet dogs.
With addition of birth rate and death rate, the site may become a simulation application. Maybe also adding a text field to input those rate to check if we are increasing or decreasing.
If I sell something to a Belgian and I'm, say, a Canadian company, I don't suddenly become subject to Belgian law. I don't have to account for distance selling regulations, data protection regulations, VAT, local taxes or anything else. I'd be subject to Canadian law, and that's all. Chances are the contract would even state that the jurisdiction were somewhere in Canada. (Yes, I know contracts aren't always perfectly binding or valid, and just because something is declared in a contract doesn't mean it's enforceable or valid.)

Consumer could sue in Belgian courts but the matter of jurisdiction would arise and that's where the claim would fail.
While the numbers indicated suggest that some people are lying, there are a couple "old guys" I know who would read this site. One is a professor emeritus at the university I work at, and he still keeps up with this stuff. Another is a guy who showed up at our local python user's group a few weeks ago. He's in his late 70s or early 80s and decided to pick up python as a retirement project. (It's kind of an inspiration, I would like to walk into a room of 'kids' in 2060 and say: teach me what you are doing). I've recommended this site to both of them.
As a father with a child with autism spectrum disorder (it is not fully diagnosed until 6-8) I strongly second to have your children tested and enrolled as soon as possible (ideally as soon as you have any doubt or see any sign). Therapies can have almost magical effects if started early, much less as time passes.
In addition to anonymoushn's correct point, I would also observe that even if we do treat infinity as a specific real number, the integration of a function zero at everywhere except one specific point from -inf to +inf is still 0. And further if we are treating it as a real number, you've now violated the uniformity constraint; P(0) != P(inf), therefore it is no longer a uniform distribution, the thing you are putatively building.

A commission in the hand is worth two in the bush...but a purchase agreement submitted by a potential buyer can have a time limit attached to it. If the seller wants to wait around, they may lose out of the initial offer, which is (most) often the best offer.

Assembly is a one-to-one mapping with machine code. 2 (fast) passes, and you are done. Compiling entails far more complex operations. while I understand that you are saying that the action of assembling is just trivial compiling, I think that compiling implies, and perhaps even means, certain operations and steps that just aren't present in an assembler.
As a Chef user, what are the honest selling points of cuisine vs. something like Chef Solo? I'm definitely up for moving to something that isn't as heavy as Chef but so far nothing has really clicked. Is it just that you preferred python? Looking at the sample code it doesn't seem more compact or sraight forward than the ruby equivalents. The excellent knife cloud bootstrap plugins, good hypervisor metadata coverage and active community makes it hard to say goodbye.

I'm sure you're not looking to go head to head with opscode or plabs, but what's the elevator pitch? I'd really love something that ended up being much more concise for the 90% of the deploys that are dead simple.

As others here have pointed out, "Asperger's" covers a broad spectrum of behaviors and it's not fair to a) put this label on anyone who displays some of the behaviors (that covers too many people), nor b) try to minimize the diversity of behaviors by focusing on just a few (the diversity is much, much greater). The same thing happens with the horribly named "gifted" label. People only focus on the high achievers and completely miss the fact that not all gifted or Asperger's fit that stereotype. It's just so easy to label people and move on without really considering what's going on. A great article called the "Misunderstood face of giftedness" on this was just in Huffington Post http://www.huffingtonpost.com/marianne-kuzujanakis/gifted-ch...
I refuse to do what I think of as "building for inventory" -- working on things that I don't see a clear downstream consuming process for -- and I try to make everything I bother with perfect and part of a flow process (never one-off). I am one of the most productive people in my office, while my coworkers are always busy, busy and can't seem to get things done quickly.
Some of the mass media articles about Zuckerberg have just been absolutely venomous taunting about his Asperger's. You can be the most successful internet billionaire of your generation and average people will still sneer at you for having a mental disorder. The stigma against it is still incredibly strong (even though it has no connection to violent/abusive behavior).

Here's one well-known example: http://gawker.com/5885196/the-tech-industrys-asperger-proble...
Take the example that I cited:
1 + 2^-25 + 2^-25 ... (2^25 times) will give you 1.

But if you do:
2^-25 + 2^-25 ... (2^25 times) + 1 it will give you 2.

Moot has a concept of "paths" which allow you to setup unlimited discussion hierarchies. All parent paths contain all the moots from the children.

We're putting together more docs to help cover these concepts soon!

Single thread (which we call a moot) doesn't support threading. If you try to browse bigger threads here in HN or in Reddit you'll soon realize that you'll get lost. Especially when you come back to the site it's impossible to know what has changed. We think discussions should be chronological.

Later we're adding support for replying to replies (one level only) and a way to branch from the main topic.

As someone who is currently looking to buy a house in the crazy Bay Area, I can tell you exactly why Redfin doesn't quite work. The Redfin real estate agents themselves aren't as dedicated to the clients as a traditional real estate agent is. Sure, you can see places, they will give you advice, and place orders for you. But with a dedicated agent who is getting fully commission, you are getting a lot more soft services than you would with a Redfin agent.

Case in point: I have a friend who was looking strictly through Redfin, and whenever he found a house he would like, he would talk with the Redfin agent, and they would get a bid together. He was getting nowhere, and what was more frustrating is that even though they had the Redfin agent, they still felt alone and frustrated.

I suggested my real estate agent. She went to his house, talked to them about what they wanted, and then proactively started looking for houses for them, in addition to him scouring MLS at the same time. She would actually suggest different areas of the Bay Area, instead of just SF because it looks like $850k won't buy you a decent house in a decent area anymore.

The other thing that is really helpful in today's market is that she encouraged my friend to submit multiple offers at the same time, ie. bidding on 2-3 different houses. This is something Redfin actively discouraged. It's a bit grey area, but in this market, you can't afford to pass up any opportunities since the probability of getting a house is so low. As well, she works for a large brokerage, so she is always trying to get the inside scoop on new houses that are about to hit the market. They still haven't gotten a house yet, but they are less frustrated by the process and they feel a lot better knowing that they are getting good guidance from someone who is dedicated to helping them getting a house.

If you are a sophisticated real estate buyer, and all you need is an agent to do all the documentation for you, then Redfin will likely work for you. But most people aren't, and in a broken market like today in the Bay Area, Redfin will be less successful, because what you really need is someone that knows the tricks of the trade and will help you bend the rules a bit.
When I was looking to buy my first house a year ago, I was pretty interested in the deal Redfin is offering, which is basically that they take a smaller percentage in exchange for more of the burden being on you during the buying process.

It took quite a while for me to find what I was looking for, so I ended up using both Redfin agents as well as talking frequently with a normal agent. I have to say even though it cost me slightly more, in the end the house I bought I found on the Redfin site but bought through the normal agent. As others have pointed out, good properties can go fast and having someone who you can call and have on the case immediately is a real asset. In my case my agent did the legwork to find out who else had seen the home and pushed the sellers to negotiate in time to edge out a competing bid - well worth a few thousand extra on the sale price.

I get the point about misaligned incentives, but I view that more as a reason to ask around and get recommendations on good realtors, rather than a reason to avoid them.
It is a git log viewer. So it follows `git log` behaviour.
But that uses associativity, and it's the associativity that fails. I believe that "a+b" is always equal to "b+a".

A more simplified version of what you say is that:

1 + x + x + x + x != x + x + x + x + 1

when x is suitably small. But to convert one into the other requires both associativity and commutativity:

(((1 + x) + x) + x) + x

-> (((x + 1) + x) + x) + x using commutativity
-> ((x + (1 + x)) + x) + x using associativity
-> ((x + (x + 1)) + x) + x using commutativity
-> (((x + x) + 1) + x) + x using associativity
-> ((x + x) + (1 + x)) + x using associativity
-> ((x + x) + (x + 1)) + x using commutativity
-> (((x + x) + x) + 1) + x using associativity
-> ((x + x) + x) + (1 + x) using associativity
-> ((x + x) + x) + (x + 1) using commutativity
-> (((x + x) + x) + x) + 1 using associativity

If you write Y as x+x+x+x, then 1+Y == Y+1.

It's the associativity that fails.

I find it hard to believe that there over 125 people who read this website and who are over 90!

I think what happened here is, some guys read this and decided to be naughty and decided to pick the max age. If lets say we provided another choice saying over 150 yrs old, I am sure it would have been picked and we could have safely ignored the whole set data points without affecting our interpretation of the different ages of people.
This is indeed the case right now. We're open sourcing big chunks of code later once they are nicely packaged and documented.
Average account age (especially for people broken down by submitters with frequency, commenters with frequency, and quality commenters by frequency) would be MUCH more awesome than age, I think.
Not really, code in low-level GPU shader language (I believe that's no longer allowed though) and compare it to HLSL. Compare intrinsics speed with inline assembly.

Sadly, we live in a world where the lie that compilers can optimize better than humans is widely spread. The reality is, compilers can optmize better than your everyday-javaguy (the kind of person who believes you can just throw more processing power at a problem while the programmer just needs to abstract ad nauseam).

I like using frameworks, libraries, high-level languages as much as anyone in here, but I know ASM will always be faster, just not always suitable for the issue.
