>> Retail is very low margin business.

Retail is a complicated beast. Walmart has a operating margin of 2% but return-on-invested-capital of 11.5% , reasonable. Which is more meaningful ? And Amazon has similar math on it's side.

Or let's consider Amazon's 3rd party retail business: the marketplace which probably has healthy margins, combined with fullfilment which is pretty differentiated: 1-day shipping, prime eligibility, largest warehouse network, etc. So maybe decent margins.
Could this help Uber?

American's seem to enjoy the "X doesn't kill people. If only more people had X, less people would have to die." argument.

I read dang's comment before posting. It still didn't help -- I can't come up with a mental model that generalizes the criticism into actionable rules for improved discussion (except as noted below).

>Everyone knows how these statistics work on a macro level. That's not worth commenting here on HN, and especially not on this story.

If statistical comparisons were obvious, and people didn't overreact with unjustifiable countermeasures, then indeed it wouldn't be important to make the point. But the world we live in is one where nuclear deaths are scarier than heart disease deaths, and shark attacks more than auto collisions.

I think you're committing the fallacy of "my social circle doesn't make that mistake, therefore it's not worth pointing out."

I can agree that users should be more careful about making the common point when others have made it, though -- I had a reply on this thread about "Uber flouted the $150 license" that I deleted when I saw others made a more informed response to the same point.

That's logically impossible. Under/Over taking doesn't mean moving faster than neighboring traffic, it means "merging into slower moving traffic". If the cyclist isn't moving into the car lane, they aren't undertaking.
Wherever there is a road, there can be rail.

Autonomous cars aren't a viable tech until the roads are reengineered with rails built in. It's just way too big of a technical problem to solve with computers alone.

Right now the death rate of autonomous cars is far higher than human drivers and it is never going to catch up given that it hasn't advanced technologically recently.

Ah, yes, if that is the alternative, then of course. I thought it was between some shortened link and an unknown domain.
All deaths are a tragedy to someone. A statistic is an aggregate account of untold suffering and misery. To be truly compassionate, we must learn to see the humanity in statistics. We must recognise that our emotional reaction to the death of a loved one and our indifference to the death of a stranger is not a sign of compassion, but egoism. As enlightened citizens, it is our duty to use all our ingenuity and effort to reduce the sum total of suffering.

This death is a tragedy. There were 37,461 such tragedies in 2016. Every single one of them matters equally. It is only by studying and analysing them in aggregate that we can prevent future tragedies. Seat belts, air bags, crumple zones, anti-lock brakes, median dividers and rumble strips are tremendous acts of compassion. Statisticians, scientists and engineers have made an incalculable contribution to human welfare.
So what happens when the three offered domains become widely known to be fake? Can this service be federated and use custom domains or is it just another game of whack-a-mole?
"The people leading the development should demonstrate that they can stop for pedestrians by personally jumping out in front of them on a closed test road. If they're not able to demonstrate this, they shouldn't be putting them on public roads."

Although the actual logistics of your proposal might be challenging (child comments point out that some speeds/distances might be impossible to solve) your instinct is a correct one: the people designing and deploying these solutions need to have skin in the game.

I don't think truly autonomous cars are possible to deploy safely with our current level of technology but if I did ... I would want to see their family and their children driving in, and walking around, these cars before we consider wide adoption.
A pedestrian struck and killed doesn’t count as “harm”?
It seems this is an argument for greater rewards for whistleblowers in other industries - not one for decreasing financial whistleblower rewards.
The problem is likely a failed ABS Brakes and on all cars. When the brake is applied and then it fails, there is less than 5 seconds to a crash and likely fatality. No time to react. Experiencing the brake failure on two cars, I have tried to get the attention of NHTSA for a decade. NHTSA has a lock on faulty research to blame an innocent driver for all accidents instead of finding the correct root cause of the crash. My estimate is 50% to 70% of all fatal crashes is caused by a defective ABS Brake.. Finally with no driver to blame, NHTSA will have to solve the correct fail mode for these crashes. The Congressional Sudden Acceleration investigation found nothing to make the roads safer and Toyotas have SA crashes today and the certified accident investigator only logs items to blame the innocent driver. Unless the braking technology is totally changed in self driving cars, I expect daily crashes with no one to blame. I have sent Elon Musk letters that the Tesla has ABS Brake issues causing crashes, but their engineers join in blaming the driver and do not fix the problem
Accident investigators are clueless
Lawyers and DAs are clueless
News Reporters are clueless
NHTSA is clueless
NTSB is clueless
Carnage on the roads goes on unabated and we convict an innocent driver.

I wonder if you could do this with a browser plugin... I may look later.
I believe this method falls strictly under deterrence.

It is not possible to extract more punishment on an individual than their death, technically, unless you believe in an afterlife.

It is not punitive and meant to 'correct' the builder; it is meant to 'prevent' the builder from cutting corners.
+1 . I always see these comments about "developers in NYC make well over 200k at established companies" and I'm yet to see instances of this.

AFAIK, only Google and Facebook have fairly sizeable engineering offices here and pay that much.

Even the large financial institutions pay most of their engineers less than 200k, maybe around 150k.

I've heard of "quants" (engineers / mathematicians) who sit at the trading desks making bank, but that was in the days of when trading actually made a ton of money, and I have to yet meet someone in person to ask them how much they made.
"ha ha only serious" it's an observation of how the world is (see: factories and recycling operations in Asia, mining in Africa), not how it ought to be.

I love the narrative this starts off with!

But, solutions... I don't see how professional ethics could actually be applied productively. And I say this as someone with an engineering background.

If a company's business is building bridges, ethics are an orthogonal concern and hence relatively straightforward to apply. But how could a civil engineer productively apply their ethics to a company who's business it is to build concentration camps? Making sure corners aren't being cut doesn't really address the problem! If it is just one company building camps in a far off land, then sure a review board can apply judgment and sanction their employees from the rest of the industry. But if your domestic society shifts to where building camps is an upstanding economic sector...

Essentially all of the funding for consumer software is based on the assumption of surveillance, period. Low marginal costs means investors desire home runs. Metcalfe's law means the introductory price has to be free. Success means users end up locked in - so even if the consumer-facing front end manages to be profitable on its own, the back end is still able to add to profit through surveillance, or at least store everything until they figure it out.

Even business sectors that should be outside sources of non-surveillance development seem to prefer sitting on the sidelines. For example, it would be pretty straightforward for banks to start offering direct public APIs for customer access to accounts, letting users choose which software they'd like to trust with such data. And then even, as an outside authority, putting restrictions on service providers about data retention. But instead the banks stonewall, and so we get surveillance-service providers like Yodlee filling the gap.

I don't really have solution per se. On a different day I'd go on about end-user Free software. But that's clearly outcompeted for the reasons listed above. When is the last time you saw a GNU TV commercial?

To add on, none of these articles seem to talk about the racial diversity in the Midwest. Yes, there is a problem with diversity in Silicon Valley and tech in general, but the West and East Coast seem to advertise themselves to be friendly towards immigrants whereas this and many other articles seem to only gear towards White (and maybe Indian, but it seems to be execs not engineers) as shown in the pictures.

Edit: I mean that it's curious that the Midwest never seems to advertise toward immigrants or minorities in tech. What motivates minorities to move to the Midwest if it seems the culture doesn't seem to support racial integration?
Why not rails for the long distance high speed travel and then low speeds off the rails for that final distance?
Sorry, I meant System Policies, the predecessors to Group Policies.
Heh, I've had a similar project on my back burner for a long time having to do with reusable Keurig filters. There are a ton of them on the market, and they all have the same fundamental design flaw: they are just a filter, without the surrounding housing with a small hole designed to hold pressure. So they all make weak coffee (and a huge mess). I would happily sink some money into the design and manufacture of a filter that actually worked. I think it could even be a money-maker, though I'm mainly interested in it for my own personal use. But I have no clue where to even begin looking for someone who could make such a thing. If anyone here has a clue I'd appreciate hearing about it.
[edit] Point made, I suppose.
Due to geofencing, we are building a sort of rails. We're creating cars that are only useful in a limited, well-mapped area.
Because if you blow the whistle you will never work in that industry again.
The title here should be amended to “...hits, kills jaywalking pedestrian...”. Let’s get the facts straight. This person was walking outside the crosswalk. The fact that a computer was behind the wheel is irrelevant. A human broke a law designed to prevent this exact scenario, and the result was both predictable and tragic. It’s terrible, but ultimately the person’s fault.
Didn't Zuck take the idea for Facebook from someone else and then run with it?
The communications gap is worse with US companies.

- "You have to speak with the sales rep for your area for that, and he's out until next week".

- "We don't make that any more." "Then why is it on your web site?"

- "The order form on your web site doesn't work".

- "Live chat is not available at this time".

- "Your call is very important to us. Please leave a message."

Companies in China seem to rely on email, and they answer emails. (I wonder if perhaps spam is less of a problem in China, because the government is very hostile to mass communications from anonymous parties.)
I understand your point. But people are capable of recognizing the tragic loss of a life while also trying to understand both the cause of it and the implications.

The victim's life had meaning. To herself, to her friends and loved ones, and all of those affected by her untimely loss. We don't know her story, nor the stories of the over 6,000 pedestrians (a number that's been increasing) killed annually in the US alone as of 2016.[0] Nor the 37,461 killed in US motor vehicle crashes in the same year.[1]

We talk about the technology, because it was involved in this woman's death and because the technology has the potential to drastically reduce the overall number of such accidents. Understanding why she died, and how similar accidents can be prevented in the future, can give society back something out of an accident that only took. If we can learn from her death, anything at all, it behooves us to do so.

Yes, it's cold. It's extremely cold. But it's something doable. Even if these discussions offer little impact on the actual development of self-driving cars, they can still impact the political debate that's only now just starting. For better or worse, there will be those who point to this woman's death as an argument against the technology. Recognizing that her death is not simply one death, but an example of a type of incident that claims thousands each year without self-driving car involvement, is critically important. At times, statistics can dehumanize and cause us to overlook the very real pain depicted as a small part of a number. But at the same time, they also permit us to recognize problems and measures ways in which we can mitigate and even solve them.

Reflections on founder mental health, coaching, a decade after losing my mom
> 1.) Drive much slower in areas where a pedestrian and cyclist can suddenly cross your past.

So essentially everywhere? I have seen pedestrians walk unexpectedly into traffic on high-speed 4-lane divided roads with no crosswalks.

> 2.) Know the danger zone. Before people "jump into traffic" or a cyclist swerve in front of you, they have to get into position, this position is the danger zone.

What "position" are you referring to? There are places where you can account for or predict pedestrians. There are also places where you cannot, such as when someone walks into traffic from behind a tall parked vehicle, where you have no chance to see them in advance.
I just find it disgusting that, as a company, they feel they have the right to act in such a way. At the end of the day I guess it's safe to assume that somebody inside or outside of Facebook has an agenda to proceed with actions like these and I'm sure there are many other cases of things like this around the world but the entire thing just leaves the worst taste in my mouth.
Rails don't work for the last mile. The great thing about cars is that they don't suffer from the last mile problem.

It seems like a much better plan is to separate drivers from other people more rigorously, and maybe mandate people drive the last-mile themselves (with AI help, obviously).
Or at least have the self driving cars driving only along specific routes well marked, well maintained autonomous driving routes similar to light rail/bus lanes so pedestrians know to be extra careful.

And for long haul trucking applications, freeway lanes at specific times of late night/early morning could be dedicated for autonomous driving.
Scaremongering based on the flawed premise that CS hasn't already resulted in plenty of death and destruction.
So, doesn't this mean you need to have a bunch of domains, none of which look like urlcanary domains? If you hide behind something like namecheap's whoisguard (customer, not affiliated with them), that would do the trick, right?
When lawyers set these things up, they tend to keep things as broad as possible. In practice this means that they can show how cool their technology is in a commercial, while showcasing your app without necessarily your approval. Obviously it would be absurd to make money of your content and not cut you in, since those types of actions ripple very quickly in dev communities.
> The point is that whether you think our system is great or terrible, you can't change it by dictum.

> "We'll just demand things change" is not a serious approach to anything.

> ...neither of us would take someone seriously who showed up and said "We have to just write 'STOP CRASHING' at the top of each file".

You're arguing (at great length) with straw men.

(I think you feel like you're being reasonable, but having words put in my mouth like that is infuriating.)

> I think it's hard to argue that things are particularly bad right now

That's the crux. It's your value judgement, and it is not legitimized by the rest of your rhetoric.
EDIT: As more is revealed about Cambridge Analytica, this clearly is "news" that requires more investigation.

My original comment was more in response to user vs segment level targeting.
Actually, raytracing is a domain with strong potential for AI, as there is a lot of work using ML models to de-noise ray-traced scenes in real time.

Edit: Yeah, NVidia actually just announced a big project on that exact subject: https://www.youtube.com/watch?v=jkhBlmKtEAk
Rails empty out into areas that are parking lots, and maybe you don't get the irony of rail but the more of it you have the less parking lots you need.

And as far as dirt roads go, if the self driving cars can't make it through well defined, paved roads what are the odds they are going to accurately navigate some dirt road?
I would be very interested if there are statistics to back up the idea that Silicon Valley startups are more successful than startups created elsewhere. I guess that would also mean defining what "successful" actually means.
I suspect that when Silicon Valley loses its dominance it will be to China, not to other parts of the United States.
Show Launch HN: Bribeshare, bribe your web visitors to share on social
Hello,

I am Hikmet, cofounder at Bribeshare. https://www.bribeshare.com

Our service makes it easy for businesses to bribe their website visitors to share. Instead of embedding regular social share buttons, we allow you to answer the "what's in it for me?" question that visitors think about before engaging in any action.

We see Bribeshare as word of mouth marketing on steroids.

With everyday people wielding enormous amounts of exposure potential, we see it in the business's best interest to "bribe" them to share.

I have been in the marketing space for a number of years and I always wanted to pay people to share my blog posts after or before reading them, so I can get more momentum. Well, I decided to do that and here it is.

Here's how it works:

1. Embed social share buttons on your site
2. Visitors come to your site, they see "share this and make a dollar" or however much you're willing to pay per share.
3. They share and when one organic click occurs, then they earn a dollar.
4. Each visitor can only share once and everything is tracked. No scams are permitted. (I can answer all your questions.)
5. View the amount of clicks the share got, what platform it was shared on, who shared it, etc.

We earn 20% of the earnings that the influencers earn when they successfully share.

Please give me feedback, check it out and don't worry about hurting my feelings.

All the best,

Hikmet

I think the reasons to still use WordPress and PHP at this point are really a mix of a few things:

1. It's very easy to install for an inexperienced person, which is a pro shared by every PHP script you can imagine. If you're making a product meant to be run on shared hosting servers or aimed at a non technical audience, you do not want to have to say 'here's how to use the command line and here's how to set up SSH keys'.

2. So many other sites use it (especially news/blog sites) that using it makes things easier for new writers or other non technical people you want to contribute content to the service.

3. If you're part of a very small agency, aren't particularly interested in the programming side or want to get something done that can be done with a few plugins and a free theme and don't want to reinvent the wheel, it can work fine there too.

Yes, it's probably not recommended for those with significant software engineering/web development expertise, and there are certainly pain points for those in those situations, but I think the key thing to remember is that its ideal audience is a much less technical one with limited hosting options and a need for easy installation over code quality.
A thing I like to do to stay in practice is to browse /r/roadcam over on reddit. I open a video at random and watch it, and try to guess where the collision (or near-collision) is going to come from.
The hope is that AV can see 360 and observe things outside of blind spots further away. So the kid running from a yard into the road after a ball should be safer, but a person walking out from behind a parked truck wouldn't.

Focus groups are not an advocate. Focus groups are not a developer with a vested interest in the feature doing what they want. Focus groups cannot be as effective.

I address this, but you seemed to ignore it.
Actually I think rhetoric matters enormously - how you frame a question affects how you come to think about a situation.

If you ask a question "through the lense of technology" ("Can we solve this hard computer-vision problem"?) you arrive at different answers to those you would get if you ask the question through (say) the lense of societal benefits or humanity's relationship to technology ("Is it ok for a badly programmed computer to accidentally kill someone"?).

I say this not to criticise the enormous benefit this technology could bring, but rather to provoke us to think about the implications of the technologies that we are creating outside the confines of an IDE.

It's a popular story, but out of all gripes you have against Zuck it's perhaps the least relevant. Especially so in HN, where the daily mantra is "the idea is worthless but the execution is".

There are many valid criticisms against Zuck, and I don't think this one quite holds value as much as the others.
