"Pedestrians always have the right-of-way."

Just FYI: In the US, this not legally true, and definitely not legally true in a lot of comparative negligence states.

While its true you can't just hit people with your car, any civil suit that is filed would be usually lost in most of these states (where lost == you may not recover money). It does vary, some states (like AZ) allow you to recover 1% even if you are 99% at fault.

In fact, what you say about right of way is not even true in very pedestrian friendly states like California. In California (and most states), what the person you replied to wrote is correct.

(a) The driver of a vehicle shall yield the right-of-way to a pedestrian crossing the roadway within any marked crosswalk or within any unmarked crosswalk at an intersection, except as otherwise provided in this chapter.

(b) This section does not relieve a pedestrian from the duty of using due care for his or her safety. No pedestrian may suddenly leave a curb or other place of safety and walk or run into the path of a vehicle that is so close as to constitute an immediate hazard. No pedestrian may unnecessarily stop or delay traffic while in a marked or unmarked crosswalk.

(c) The driver of a vehicle approaching a pedestrian within any marked or unmarked crosswalk shall exercise all due care and shall reduce the speed of the vehicle or take any other action relating to the operation of the vehicle as necessary to safeguard the safety of the pedestrian.

(d) Subdivision (b) does not relieve a driver of a vehicle from the duty of exercising due care for the safety of any pedestrian within any marked crosswalk or within any unmarked crosswalk at an intersection.

They seem to use 2.5 seconds as the standard for drivers to perceive and react to an obstacle, which based upon studies covers 90% of all drivers. 1.5 seconds to perceive, 1 second to react. Then you have maneuver time on top of that 2.5 seconds.

Given this, 1 second seems very low. A large percentage of drivers would probably plow into them at full speed.

Can you reference any stories? I can't find much.

But the implication that you need to use high voltages isn't true. You can easily feed 24/36/48 volts into an inverter. The high current potential only acts weirdly when you short it out, which is where a couple fuses can prevent issues.
Speaking for myself, but also probably for a lot of others, I've wanted Facebook to die for years now. The discomfort around the privacy and toxicity has been slowly building, but the critical mass of the thing makes it hard to break away by yourself. You lose touch with people, you miss event invites, etc.

So maybe, for a lot of people, this moment of collective outrage is an opportunity to get out. If we can all quit at once, we can all be free.
Facebook owns Whats App. It's one of the first thing they acquired with IPO money.
IIRC, that was an acquisition. I interviewed there, they were a block away from Real Network in Seattle, and mostly consisted of alumni from there. In 2004, Real Network was A Big Deal.
Ask HN: Carrier advice, a bit confused
Little background. I am a three year experienced Python Backend dev. Currently I work for a start up that pays well. I am at crossroad currently. I am juggling couple of carrier choices but cant seem to decide which way to go.

Options

1. Slog on LC and aim for BigN.
2. I already know JavaScript and have built front
ends. Pick up React and along with Python
transition into a Full Stack dev.
3. Take a plunge into Machine Learning.

I am unable to choose among the three. I would appreciate if you guys could critique each of the choice. I am really looking to a discussion over these three options. Thanks.
Wait, you don't cross lanes of traffic staring at your phone? That seems to be the new way people want to commit unintentional suicide.
Have you actually talked to a 19yr old recently? Serious question. Because you seem to lack serious perspective about how a 19yo acts, thinks, or behaves when adults aren’t around.

Also can you explain to me how people submitting personal information to a random form from a college kid is not dumb? Facebook the product didn’t even exist at that point by the way and the information collected was more like email address, nothing really more nefarious than that.
I agree; and particularly like that you mention this is a brand new Volvo -- I regularly drive much faster on roads that are likely to have deer -- and this driver is clearly not paying attention. I think the driver should be considered for manslaughter charges (to which, as they were an employee, Uber is civilly liable for)

They will probably lose in arizona (In My Lawyerly Opinion) but Uber will settle it out anyway.
It's not only comparative negligence, you don't have to always yield. In fact, Arizona has a weird set of rules that would make this exact set of events a law school exam style question:

Arizona: Vehicles must yield the right-of-way to pedestrians within a crosswalk that are in the same half of the roadway as the vehicle or when a pedestrian is approaching closely enough from the opposite side of the roadway to constitute a danger. Pedestrians may not suddenly leave the curb and enter a crosswalk into the path of a moving vehicle that is so close the vehicle is unable to yield. Pedestrians must yield the right-of-way to vehicles when crossing outside of a marked crosswalk or an unmarked crosswalk at an intersection. Where traffic control devices are in operation, pedestrians may only cross between two adjacent intersections in a marked crosswalk.

One saving grace for any plaintiff is that in AZ you can recover 1% damages even if you are 99% at fault.

Its not really relevant how much is spent per homeless person, what you want to know is how many people that money keeps off the streets. If you spent 100M and kept all but one last homeless man off the street by your metric you've spent 100M/homeless, while in reality you've spent 100M to keep all but one off the street.

I have a feeling this will be a blip, but I also have a feeling this saga will lead to a qualitative change in the air. The level of trust FB has with the general public will fall. People will become more suspicious of it over time. It will make them vulnerable to being "disrupted" by some other service, technology, or philosophy.
Swimming with Sharks by Joris Luyendijk (about the finance industry in London) argues that amoral actors develop and thrive in environments where they get a “bonus” for good performance but fear no “malus” if their choices backfire. Organizationally, you see banks with separate, impotent, internal risk and compliance departments, while their “front offices” get literal cash bonuses for successful short term gambles. No rational actor sees any benefit to fighting for change: there’s no lasting result but personal ruin.

Developers have the power to refuse bad actions, especially like you say in a job-rich environment. But unless software developers experience risk consequences for developing something bad, some number of them will not obey their conscience.

I did Coursera's "Introduction to Machine Learning" by Andrew Ng back in 2013 and loved it. Great tutor, good course material - and it looks like Coursera is still offering this course though I am not sure if it is still free. The course is language-agnostic and uses Octave (an open-source Mathlab clone) for assignments and examples.

One has to remember that these news orgs are in competition with Facebook and their coverage should be considered with that in mind.

The eurocrats must be loving this, instead of scrutinizing their discriminatory tax proposal targeting our tech sector our press and politicians are attacking our companies for them.
Despite the tough situation for Facebook, I suspect they are somewhat pleased that the focus right now is on an older data breach instead of on the toolset and functionality they provide currently that people aren't talking about.

Although the media is currently focusing on Cambridge Analytica and the simple targeting they offer to ad buyers using likes/interests, the reality is that advanced buyers can buy/collect data elsewhere, chop and segment it as they please, upload names and email addresses, and have Facebook automatically match the data that they have with fairly high accuracy to users on Facebook.

This removes any of Facebook's "liability" in terms of targeting using likes and interests in their system, but still allows anyone with the data and know how to do as they please and still reach all the users they want using Facebook's tools.

Sure, Facebook will take a hit with this, but ultimately Facebook can and will get away with the current narrative that this was something that only happened years ago and they are better now.

To me, the current toolsets and targeting using your own uploaded data is what is even scarier. Facebook will just shirk all responsibility this way but still allow for the same thing to happen in the future.

LIDAR also has limitations on angular resolution just as a function of how the sensor works. It's entirely possible that the size of the person/bike on LIDAR was just too small until it was too late to stop.

Why it didn't even appear to try to stop? You got me, refresh rate on the LIDAR? LIDAR flat out being mounted to high and relying on optical sensors instead for collision avoidance of small targets (like a human head)?

I'm guessing, I'd love to see an NTSB report on this.
Whats the point of a safety driver who's eyes are not on the road? Pretty easy to monitor if the safety driver is paying attention or looking down every second like this safety driver was.

Agreed, I grew up in Toronto with a small yard but my brother and I rarely used it. We would simply go to the park or the school yard. We did use the pool at my grandmothers but that was pretty extravagant for the 2 months a year you can use it in Toronto.

I find this so hypocritical. If they tried to do the same thing for gay marriage or doctors mutilating children with sex changes the internet gestapo would burn the internet down in rage.
I don't understand what you mean by self-updating. You still need to "friend" new people. How is that different from adding them to your contacts?
Pedestrians do always have the right of way, but they bear a bit of responsibility as well to make sure the driver is aware of them, and not just walk out into the road. I have been on both sides of the wheel here, and it can never be assumed that a car knows a person is there.
The parent comment referred to "every" recipient knowing ones email address and "anyone who has hacked those recipients". The idea seems to be that all email addresses become "public". But this seems to assume things about the user and how they use the email address.

What if a user has an email address that she does not use to send mail? She does not use this account to send mail. She does not need to send reply mail. She has other email accounts she can use if she needs to send mail. If she only shares this address with one sender, then is this not at least a "semi-private" email address?

Back in the early 1990s when email accounts started to become easy to obtain, I routinely had accounts where I only received mail. I only gave these addresses to one or a few senders. I did not use these accounts to send mail.

I do not use email as avidly as I did back then, and maybe things have changed, but I would be a little surprised if today when a user sets up a new email account she starts immediately getting email1 because "all email addresses are public", before she has given this address to anyone. The address is "semi-private" unless and until the user decides to disclose it widely. She may choose not to do that.

I've been staring at those myself for a couple of hours. My best guess is the crosswalk was moved, but the paths were left. There's a lake nearby and tons of parking under the overpasses, with trails and picnic areas.

Also, the woman was right under a working street lamp. And as was stated in an earlier article the car continued on at 38 mph after the accident. The bike ended up 50 yards down the street.

EDIT: "That spot is east of the second, western-side Mill Avenue bridge that is restricted to southbound traffic, and east of the Marquee Theatre and a parking lot for the Tempe Town Lake. It can be a popular area for pedestrians, especially concertgoers, joggers, and lake visitors. Mid-street crossing is common there, and a walkway in the median between the two one-way roads across the two bridges probably encourages the practice."

"Pedestrians can cross a street without using a crosswalk in many instances without risking a jaywalking ticket, but Arizona law requires pedestrians not using a crosswalk to yield to traffic in the road."

Just look at the work of Cambridge Analytica. Soft control is in the hands of bit players now. Surely large players (google, governments) can be more deft with how they ply the waters.

Two thousand tv stations? How about 20 million (Youtube)? In an information theoretic context, scale is irrelevant.

Individuals are categorized, personalities are inventoried, and experiments are run. Maybe google doesn't do it, maybe they provide the conjugate interface to companies that actually do the inventory, the effect is the same. Havoc on an open society.

Facebook: The Last Days of Reality (2017)
I don't know how you can watch this video and then say that they should "maybe do more testing in controlled environments".

This was a complete failure and Uber's cars should be immediately banned from testing on public roads and there should be investigation into their practices to ensure public safety while testing their vehicles. If they rushed it trying to play catch up with Waymo they should be punished.

Personally I see this as a Therac-25 situation.

> We should be willing to share space-based early warning data and technology with the Russians to head off this crisis.

That's interesting to think about. It makes logical sense at first, but I doubt it is realistic.

Thinking about it some more, it seems having a better detection capability means having a higher chance of shooting the missiles down. That can then be used by the aggressor to dampen a retaliatory attack. (Say we give it to Russia. They attack first. Then when we retaliate, they use our advanced system to know the trajectories of the incoming missiles and use that to shoot them down. Our retaliatory attack fails and we lose).
That's a strong assumption to make, that a human could have done better. It was dark, night, nowhere near a normal crosswalk, and not where I as a driver would normally expect a person to be. I think it would have been hard for even the most alert driver to not hit this person in this circumstance.

What precisely is "research"?

Political research?

Human behavior research?

Business viability research?

Sociology research?

Market research?

While it's pretty clear Aleksandr Koga violated Facebook policy (and is guilty breach of contract, etc.), let's not pretend there is some universal standard for good and bad use of the kind of data Facebook collects. Or be surprised that the data is inevitably used for -- gasp -- profit.

I appreciate the transparency.

A few years ago I was testing a service acquired by Dropbox and they updated the scope of the Dropbox acquisitions program on HackerOne to exclude said program while I was in the middle of testing it and I didn't notice (checked later with the "last updated" diff). Unfortunately the vulnerabilitie(s) I discovered didn't count and their reply was all "no harm, no foul, thanks anyway."
Usenet may just be the solution for the time being, especially for some of the displaced subreddits for interest specific discussions and posts. At this point a protocol looks like it will be the answer like email, IRC and XMPP, but for forum discussion instead. If IPFS makes some headway with having dynamic content, that may work better, but I'm not sure where that is at right now.
There would still be situations when you'd be attempting to detect a human with a hot asphalt background. Such as a crosswalk at the base of a hill (C is the car and X is the crosswalk):

Meh, I think they've grown up some and see what Amazon has done. Building infrastructure services for customers adds long-term revenue. BMW doesn't make you buy fuel injectors from someone else.

This. This whole scandal is basically a fake story invented by the media as revenge.

FB has clearly done some things to get where they are that many would find challenging, but in the end if Facebook has an achilles heel then it can only be Facebook itself.

I think you’re comparing object detection to high quality photography though. There are plenty of options that can detect objects at night. Even cheap infrared technology, I would think, would be sufficient for picking up moving objects at night.

I don't think that's likely at all.

This isn't plugging a generator into your house when the power's out. This is a system that's connected 24/7. That's difficult to do, requiring careful synchronization or isolation. Getting it wrong is probably harder than getting it right.
If this is the only data point then uber self driving cars are about 50 times more dangerous than average human drivers (see numbers quoted repeatedly elsewhere; uber has driven about 2 megamiles; human average is 100 megamiles between fatalities)

If that's your idea of adequate, you'd be safer just vowing to get drunk every time you drive from now on, since a modest BAC increases accident rates, but not by a factor of FIFTY!
>The interior view tells you everything you need to know about why anything except perfection in self driving cars will lead to more accidents

Ah, no, the cars only need to be better than humans, not perfect. This seems self evident, so did you mean to communicate something else?
That's the purpose of news media like The New York Times. At first the already anti-fb people delete their Facebook accounts and create hype, the media reports it (a newspaper in this case), and more ordinary users get to know the trend and would consider doing the same.
Exactly.. creative uses of federated and decentralized social networks, especially using tools like blockchain, will allow us to filter our content and provide us with avenues for ad-free networks. Rich people shouldn't be able to propagandize poor people with advertising in exchange for educational tools. We are still exploiting the poor and are a racist colonialist nation that facilitates generational wealth and land ownership based on past exploits and transgressions.
