I researched this for myself a couple of years back and found a couple of things but only speak from my personal account:
1. There are a couple of different options, the first being done completely without surgery, and the second where they cut the lens and 'flap it up' (literally) and then do the laser surgery. Obviously, the second option is more complex and as a result can result in more problems.
2. A lot will depend on how thick your lens is. I was looking at it and they said that as I had a thin lens, it drastically changed my options. It also raised the risk as they only had one chance (if you have a think lens, they can do follow-up laser surgery to fix mistakes - no such luck with me).
It must be said, that overall the chances of anything going wrong are less than 1% or something insignificant and in most cases you will just have the same or slightly worse vision. I just wasn't willing to take the risk given I had no chance for fixing it if they went wrong.
Sorry it's not data - just my personal experience a couple of years back.

This warmed my heart. And thinking about it from a business perspective, not everybody needs to own their own self-driving car. Ie. it can self-drive itself home for use by the next person. Which means economically, the car price can be many multiples of the cost of current cars (imagine a $100k car that is shared between five families rather than five families each with their own car).
Or like myself, hire a firm once in your career, assist to the free government course and do it yourself in the future. The trick is really learning what they are looking for in the write up and scientific audit. The rest of the claim is easy. And once you're approved, you usually don't get audited thereafter.
When they drive entirely on Google property (like this parking lot), they don't need controls. If they want to drive on public roads, the law requires manual control.

They should add a table, or two sets of seats facing each other, and an optional table that pulls out between them. Then show 4 people in the car, having a little business meeting on the way to their office, or have a family of 4 in the car, eating sandwiches or something on the table as they go to school.

That should be one of the key points, you can use this time productively, and not just spend it looking out the windshield. You can visit with your children on the way to their school, and not have your back to them as you divide your attention between the road and their conversation. Show a side-by-side of a parent driving, scatterbrained and frustrated, then show one sitting next to their child in the automated car reading a book together as it drives.

Well, given that the original target for Go was C/C++ programmers, the stance on error handling makes perfect sense.

Exceptions are arguably one of C++'s largest mistakes, and it requires careful thought to write code in a completely (e.g. strongly) exception-safe way (not to mention it's caused somewhat of a fracture in the C++ community over the years...). Presumably, this is why they don't exist in Go, and it's certainly why they don't exist in Rust.

FWIW, I'm a C++ programmer, and I was a C programmer before that, so my experience with Python is rather limited.

Slack's blue "unread messages" banner should be a deal-breaker. I feel like I spend 10% of my day clicking around on Slack trying to get all the channels to realize I have read all their messages.

Ask HN: Computer nostalgia
After spotting numerous 'Learn To Code (tm)' articles today, I'm in a nostalgic and reminiscent mood.

What fond memories do HNers share of their early computer days (especially if you're over 30).

Mine include learning to power up our first IBM PC XT and start FriendlyWare (http://en.wikipedia.org/wiki/Friendlyware), before I could read (involved detailed handwritten instructions from my dad, and matching up keyboard keys).

Oh, and only being 'allowed' on the computer for an hour a day :P

Unfortunately, the IRC gateway causes a bad experience, not so much for the people using IRC, but for the people using the real Slack client. Slack apparently doesn't recognize username mentions ("@joe123") coming from IRC, so everyone needs to add their username to their list of highlight words so that the team members using IRC can mention them.
Peter Watts' novel "Blindsight" immediately springs to mind, in which the aliens are able to disappear in front of someone within an environment capable of scanning their brains.
I think there's room for a control system that gives a human a reasonable degree of direct control over the car's movements, while still having it be able to refuse potentially unsafe commands.

Compare it to a microwave oven. The microwave flux inside the oven is high enough to cause severe burns if you were exposed to it, but the system is designed so that it won't run with the door open -- and it's fail-safe, in the sense that any failure (or combination of failures) is overwhelmingly more likely to result in a safe shutdown than in unsafe exposure.

It's still possible to burn yourself on hot food, of course, but my point is that nobody thinks of a microwave as a dangerous piece of equipment that you need to be "qualified" to use, in the way that they think of a car or a table saw.

> Hachette look bad

How does it make them look bad? If they had said "Hachette chose not to take us up on this", then sure, but as it stands, Amazon made the offer, and Hachette is deciding what to do with it. That's entirely reasonable.
Actually you are right - I missed it the first time. My mistake. Based on a quick skim, it looks like Piketty is assuming far more than r > g (which is of course necessary), but there does appear to be some sort of distributional theory.

Based on a first skim (I'll take a more detailed look later), inequality appears to be a function of (r - g). I.e., r > g does not imply increasing inequality, the magnitude of the inequality merely determines the level of inequality. Seems to disagree a bit with the newspaper summary of Piketty, but I'll have to read more carefully to be sure.

As long as it's safe (duh) and moderately comfortable, I'd be just as happy to read or suchlike. Chances are these cars have good internet connectivity as they're probably going to be used in cities and you can stick an arbitrarily large antenna into the car body, so work, gaming or video consumption are practical too (on your tablet or other personal device). what else do you need - a cup holder and easy-to-clean interior?
NVidia's G-Sync is almost as kludgy as Voodoo Graphics. In theory it can be properly taken advantage of by a well-written preexisting game engine, but there are also a ton of games out there that assume a fixed limit of 60FPS and will see no more benefit than if Direct3D were to start doing triple buffering. And the idea of ripping a PCB and power supply out of your monitor and replacing them is definitely as uglier than a VGA patch cable. Fortunately, commercial G-Sync monitors will become available a lot quicker than the 2D-capable Voodoo 3.

No, this is only under the 1st born approximation, in the far-field and without the 'dish' shape intrinsic to propagation. A lot of times this model doesn't work.

I feel exactly the same way about the app business. I don't want an arbitrary and disinterested third party in between me and my customers because I believe very strongly that in the long run a strong and direct relationship with my customers is the key to a sustainable business. The iOS app store is particularly egregious in this respect because I can't even contact users that report problems. The Google Play store is slightly better in this respect but I'm still not comfortable with the idea that my entire online presence can be switched off at will by some overzealous algorithm.
I didn't create the chart. The point I was trying to make is that each of these companies is a player in the industry and has either tracking data of their own and/or they're connected (directly or indirectly) to various data brokers. The chart greatly simplifies reality - it it represented all the interconnections between individual companies it would be vastly more complex. It can't do that because most of these connections are known only to the companies involved.

This trivializes everything interesting about this case. Because this argument was previously had with Microsoft & Netscape. And Comcast and Netflix. And Amazon has a huge stake in two major policy issues upon which this touches:

(1) Monopolistic collusion in e-books; and

(2) Net neutrality
Charlie Stross (cstross here on HN) has an interesting post on this:

By driving down the unit revenue, Amazon makes it really hard for publishers—who are a proxy for authors—to turn a profit. Eventually they go out of business, leaving just Amazon as a monopoly distribution channel retailing the output of an atomized cloud of highly vulnerable self-employed piece-workers like myself. At which point the screws can be tightened indefinitely.

How about something simple like telling the car, "back up 10 feet" or "move to the spot across the street". This is dead simple short range routes...
It is sad that hachette is getting authors to write badly about amazon on blogs and on facebook. It is evident that Amazon.com is right and hachette is wrong.

Why do we need these scummy publishers anyways? Good riddance.

I'm a Canadian who moved to SV.

I, personally, would have preferred to stay in Canada but finding a job is a right pain in the ass. American companies will fly you in on their dime, while Canadian firms won't even give you a phone call. It would even help if these companies were even offering competitive wages.
It's actually 80% of the salary for any work that has been done in R&D, but like you said, most of the work isn't.

A few years ago a lot of stuff could be considered as work "between two uncertainties", including non-engineering work such as graphic design, but the rules are much more strict nowadays. I think they still give credits for things that are way too simple to be R&D (ie: normal problem solving), but we've been doing [small] claims for the past 3 years and the rules have been tightened a lot.

Also, doing a claim requires you to provide evidences that you were following a certain R&D methodology. It's definitely worth it, but it's a pain.
This article is junk. It describes in very alarming way space junk, but it never even mentions atmosphere drag at LEO and natural orbital decay. ISS has to periodically increase its orbit and it already brought down Skylab and to some extend Mir.

Exactly - you were working with a well engineered system that could handle failover. Simply installing an NFS server on an Ubuntu VM isn't going to come close to the reliability that you'd want for this job.
Can you force Walmart to put your products on shelves? How is it OK for Hachette to force Amazon.com to put the physical books on shelves?

One easy way to fight Amazon would be to include a DRM-free digital copy download for free with every physical book purchase. Of course, the scummy publishers won't do that.
> As a customer I see it as a feature that Amazon don't allow people to to collect my data, I bought the book at Amazon, nobody else should know the details.

I'm not sure the situation is that simple. You bought the book through Amazon, but (in this case), you bought the book from the other poster. Putting them closer to, say, a shopping mall. As a shopper, who's has a stronger relationship to you—the store you bought something from, or the mall you bought it in?

And for the seller, it means that your only "customer" is Amazon. Who doesn't really care about you at all. If I were a seller, I'd rather have my customers be the people who are actually interested in the product I'm selling.

When commerce goes well, the buyer and seller create a relationship that benefits both of them. With Amazon being a strict gatekeeper, there's no way for that relationship to form, and the seller ends up being an interchangeable name on a screen.

People want to know where they are going. Very few, if any, people would be happy looking at where they've been. The dash is most likely two-fold: they have to cover up what's behind the dash and they need a place to put things like air bags. Finally, if I was designing this, I'd want it to feel enough like a car that people fully recognize all the ways it's not a normal car to increase their excitement about it. Just like they put a cartoon face on the front, complete with a nose: make people feel good about it.
Whatever the future is, it will most likely have ports available in most platforms.
Edward Snowden: I was a high-tech spy for the CIA and NSA
This topic has generated a variety of coverage, presumably in part because the negotiation is with a book publisher instead of a supplier of a different type of product. Some of the coverage has expressed a relatively narrow point of view. Here is one post that offers a wider perspective.

http://www.thecockeyedpessimist.blogspot.com/2014/05/whos-af...

Apart from the amusing optics of "this topic has generated a lot of coverage, but here's a blog post that sees our side of the story", it's worth knowing that this "wider perspective" is that of a very small literary indie publisher that basically says two things:

* Hachette is gigantic

* Selling books online is great for indies

Neither of those points has much to do with the issue at hand, and, in particular, I'd suggest that selling books online is great for indies so long as Amazon sees the dollars involves as a tiny rounding error.

Well, if I lived in an apartment building, I'd like to have real neighbors, people that speak my language, enjoy a sense of community, and friends in the building. It would get quite annoying if I come home every evening to a new set of people on vacation or backpacking, and checking in and out of the surrounding apartments. The building shouldn't be a hotel, it's my home.

Now, I've used Airbnb a dozen times, but I can see the concern for people in the above situation. I've had people ask me when I'm renting certain Airbnb apartments if I live in the building, and they seemed a little upset with the idea of me just passing through for a week.
I'm thinking about this basic idea: We have, in this case, a machine that is doing the job that a human driver would do - A machine replacing a man.

My question is: Should we be happy about this? Or should we be sad?

This time, we have a machine replacing a driver. In the future we may have machines replacing teachers, doctors, carpenters, artists... even lovers and machine makers.

So, my question remains: Should we be happy? Or should we be sad?

Normally, in science fiction movies, when the machines become intelectually smarter than humans, they try to destroy humanity.

But if, in the real world, they just become smarter than us, and just replace us in every activity. Then, what would we do?

1. Less pollution than what we have now given that many people spend time hunting for a park when they arrive, or drive five-seat vehicles even though they're alone or with 1-2 others. I read something saying that in a city centre, often 30% of traffic is simply people hunting for a park. I know when I arrive near my office, I can spend 5-10 minutes driving around trying to get an all-day park. Three times a week I'm driving an SUV that can seat five and has a large boot (passengers are my wife and toddler), the other days I'm in a five seat sedan (and solo).

2. I'd say that depots will be interspersed around the city and suburbs, for one thing. Cars might move from suburban depots over night to densely-arranged city parking/depots during the day, waiting for the evening rush. A car that dropped you at work after your run in from the South is then immediately free to take someone from the city centre down South again, or be available for a courier job, or a tourist leaving a city hotel for a day trip. The mesh of cars communicating will determine the most economical use of the vehicles and anticipate demand. Further, cars communicating with each other will mean that typical causes of congestion (like traffic lights) will be better handled and less of an issue.

3. Taxis are expensive partly because there are salaried humans driving them. If these are electric vehicles and solar charged, fuel and driver are largely out of the equation.
> Try Scala.

Aiui folk who love Perl tend to have a natural affinity for Scala. Stevan Little (the Moose and P5 MOP guy) chose Scala for Moe and I'm pretty sure he enjoyed it.

I'm in to P6. ionforce, please indulge/educate me:

> {Scala|P6 is} a very expressive language that does not sacrifice on power (JVM/type safety).

I hope you see where I'm coming from and are willing to play ball. :)

First and foremost, P6 is incomplete, immature, slow, etc. and almost no one is using it to do anything serious. Aiui Scala is used in a wide range of production settings. This is likely the end of any comparison for most folk.

Scala runs on the JVM. Aiui there's no attempt or intent to run it on anything else. Rakudo (P6) runs on the JVM. It also runs on other VMs including MoarVM. See http://moarvm.org

Scala can "seamlessly" call Java code and vice-versa. Rakudo/JVM can call Java code, but it's currently ugly looking. Java code should be able to call P6 code using Rakudo/JVM but the necessary work isn't complete.

Aiui Scala has solid concurrency and parallelism features. P6 has a good story regarding the language's design as it relates to concurrency and parallelism, but implementation only began last year. See http://jnthn.net/papers/2014-nlpw-reactive.pdf for some of the best Rakudo currently has to offer concurrency-wise.

Scala does type inferencing and you can add explicit types. Its type hierarchy is Java's. P6 also does type inferencing with optional explicit types. But it's type hierarchy is not the same as Java's.

Scala has traits, pattern matching, and higher order functions. So does Rakudo.

> But no, I'm not bitter. =)

Of course not. There's more than one way to do it. :)
