Alternatively, if you don't want to spend any more effort on it, why not find a coauthor. Someone can take the text you have written, update it and refactor it and generally fix it up.
1- Considering fuel density and probably 4 running engines, autonomy would be minutes, while all aircraft are required to have at least 30mn reserve.

2- FAA will never certify such a thing. This leaves only the experimental option, with all that entails commercially.

3- Ballistic parachutes : They are very heavy and it costs 10k to repack every couple years. Plus it's basically a rocket firing out of the plane, another hurdle.

4- Insurance : Who would insure such a thing ? It is hard enough for a certified GA plane.

5- Noise restrictions of two to four jet engines in an era of going full electric, even for planes (pipistrel anyone ?)

6- Autonomous drones can be made, that fly and land alone. Yet, we don't have any GA plane doing the same and have to pass complex exams in order to fly an aircraft. It will be the same for that one, not necessarily because it will be needed to pilot it, but to guarantee airspace security.

7- Good luck with talking on the radio with all the noise + wind. Once again, this is mandatory in many airspaces and probably all where such a machine would be useful.

8- Weather : I guess you probably have never ridden a motorbike in the pouring rain. Now imagine being cold to the bones and having to keep managing that aircraft, navigating and communicating. Good luck with that.

9- Loads of comments mentioning Tesla and SpaceX. Well, there is a sizeable difference with them : the market size.
This company is also facing stronger regulation than Tesla, while having not a hundredth of the funding.

10- Numbers are already bad for GA airplanes with autopilot and al. But any failure on such a thing would almost certainly result in death. + Ballistic parachute opening requires man to be strapped to aircraft.

All things factored in, it feels like yet another project surfing on CAD generated hype, out of touch with most real world problems and justifying it's existence through being a "Moonshot".
But we are yet to see any successful moonshot. Let me explain : Companies like SpaceX or Planet where built enhancing the tech that was already there and R&D could be done with ridiculous amounts of funding. Musk's track record was also incredible at the time, with two major exits (Zip, PayPal).

It is sad to see history repeating itself so often: You are basically promising what helicopters were supposed to become and yet they are far from ubiquitous despite their high efficiency, speed and load carrying abilities. I do believe in some VTOL projects but most of them are ridiculous and won't go out of the R&D phase.

Best of luck in any case. I am ready to invite you for dinner should you manage to have a working prototype in two years.

Where I live (dublin) there's a persistent tourist subculture that photgraphs doors of georgian buildings. I've met several tourists with irish surnames who set out to visit every pub that has their name (hard work if you're a murphy, kavanagh, ryan...). I met a chinese-australian couple doing an "ancestry trail" visitng the ancestral villages of their in-law.

That kind of stuff is ultimately just a frame. A way of exploring, selecting destinations, and allowing the unexpected to happen. The premise itself isn't the point. The premise is a way of facilitating harder to target stuff: meeting people, exploring.

I've heard similar criticisms of photo-takers. They're more concerned with photos than experiences.

These criticisms and accusations of shallowness are shallow themselves, and uncharitable. Collecting countries, places, pubs, doors or whatnot is just a way of deciding what to do next, and allowing experiences to happen themselves.

Listen, my sense of humor and personal politics appear to be exactly opposite of most HN readers, and of the moderators.

In my view, I am frequently down voted because people don’t seem to get my sense of humor or because they tend to be precious liberal snowflakes. I view that as my problem. I am a guest here, and it’s important for me to behave according to the customs of their house.

But I feel the overall product is amazingly good considering they deliver it to us at the low low price of free, and with essentially no advertising distractions. That’s a pretty precious thing in my humble opinion.

I don't like that you are equating this with any other car accident.

Uber made a vehicle that can zoom around the roads unassisted. You can't just put something like that out there and disclaim responsibility by assuming that somebody will sit and be ready to brake at the right times. Even trains have a 'dead man's switch', where the train stops if the operator is unresponsive.

What they did was incredibly irresponsible, they have been running an experiment on public roads with the lives of the general public at stake. For this they need to be held responsible.

This is so true. I spent 3 years travelling through Europe in a converted military truck. I would say that of the 24 countries we have "been to", we have only truly known 2 or 3 (and of those, I was born in one, and now live in another). That is despite having spent months in many places, city and countryside alike. How anyone could ever consider "doing europe" in anything less than a lifetime is beyond me. City-hopping, and going to the typical instagram pictures to take more of the same is not travelling, IMHO.

I don’t know your needs and goals, and maybe it has to be HTTP, but what about handling the sockets yourself?

People could then use netcat to send and receive, and the server could block either end until someone connects on the other end. Personally I would really appreciate a tool I could connect to with netcat or anything else that speaks TCP. I don’t know how someone would use the service from javascript though.

No buffering needed by the server. If either end has to be asynchronous, just run in background + nohup if you’re calling this from a shell.

Maybe some inspiration from how blocking FIFOs work on Linux: http://man7.org/linux/man-pages/man7/fifo.7.html

You could even do a non-blocking version which just refuses connection. netcat can be set to retry: https://unix.stackexchange.com/questions/432249/nc-to-retry-...

I realise that this doesn’t make it easy to indicate which pipe one wants to connect to.
Indeed. If your car's power cuts, or breaks fail - the odds of you surviving are incrementally getting higher every year we're on the road. Cars are getting safer and safer, but surely part of that is due to the fact they're on the ground.

If I'm even 10 metres under the ground, flying at 50km/h, if this device fails, of the battery runs out, you're not gonna live to the tell the tale. There is no parachuting, no way of gliding safely to the ground (like planes and helicopters). What is the safety net?

I can't ever see a world where even a minority of the population adopt flying cars. The chance of catastrophic failure (death) is too high.
The Question Almost No One Asks – Who Is the Thing For?
Something I can relate to, having "done" 85 countries myself (yes, I'm one of those 'shallow' travelers who counts countries).

This article is right in some ways. It's right in that deep travel experiences are almost always more memorable than shallow ones; that traveling by hitchhike will get you more face time with locals than traveling by rent-a-car. If you travel to truly understand a place, you need to spend real time there (I define 'real time' as at least 2-3 weeks, which is an eternity in travel world, since you really fully immerse yourself in the place during that time).

But it's wrong to try to define a right way to travel, as if there is some authentic travel nirvana that all travelers could or should reach.

First of all, it depends on what kind of traveler you are, and why you travel. If you travel to learn about as many places as possible, because you crave exposure to new experiences and cultures, and you know that every time you go someplace new you learn something new that you never would have known if you hadn't gone, travel has to be somewhat of a quantity game--unless you are a full-time traveller and have the luxury (or the tolerance for nomadship) to live on the road.

But most of all, there really is no 'wrong' way to travel.

There will always be people who criticize Club Med-goers and cruise-takers for only dabbling in 'tourist traps', glampers for not doing 'real' camping, backpackers for living like 'hippies' without jobs and 'vacationing' in other peoples' poverty, hostel-stayers for hanging out too much with other tourists, expats for isolating themselves from the countries they live in, students abroad for not making friends with locals, homestayers for not learning the language, peace corps volunteers for being neocolonial, missionary trips for dressing a vacation as charity...at the end of the day, every traveler is trying to explore their horizons at their comfort level, and no one who travels is truly ever "authentic" in their experience, no matter how many chickens they pluck themselves or squat toilets they use.

All travelers are just visitors, and before long they will leave, and everyone who knows them on their journey knows that their stay is temporary, whether it is 3 days, 3 weeks, 3 months or 3 years. The best you can do is learn as much as you can in the time you have, be open minded, and take your lessons with you when you go home, or to the next place.

Unless you're moving to a place permanently, starting a family and plan to die there, you're a transient, and you have no right to criticize how other people choose to be transients in their own way. Every traveler is better off for the experience and the world is better off for the cultural exchange and greater global understanding facilitated by travelers.
My guess is that the biggest use cases will be relatively “boring” logistics problems. I use quotes because logistics problems are not typically considered sexy, but they sure are the foundation of a lot of businesses when properly executed.

If you start including ideas like military uses and public safety uses, which typically have substantial logistical components, then I imagine the scope of possible problems that this solves becomes more obvious.

Yeah, recursive descent is just the best. I've played with a lot of options, wrote my own parser combinator and packrat libraries and a Pratt parser. By now what I have settled on is recursive descent until I reach an expression, then switch to a Pratt parser. For me, that's the best overall tradeoff that I've found.
How to graph your data [video]
The Ars article above is from the week after the accident.
Only if you jumped in the field of vision of the car. Drivers are supposed to be able to stop within that field of vision. Driving faster than that is unsafe. If you jaywalk but you are not in anybody's field of vision and still get hit then it is the drivers fault for driving too fast and not being able to stop when they see you in the middle of the road.
Why do comments here suggesting that there are compelling arguments concluding that adjusted wages are nearly identical get flagged and down-voted? There is certainly a debate to be had, silencing the other side suggests weakness of one's own position. I have never seen a good rebuttal against the adjusted wages are very nearly equal position. Things always get shut down, shouted down or otherwise silenced in some way. I would love to see direct claim-rebuttal positions taken with opposing reasoning and data.

Here is a case in which I think you do not engage in the most charitable interpretation: 'You're saying "has now been flagged" like I called for all women to be killed'
A more charitable interpretation would have been that I wanted to make clear that what I responded to can no longer be seen. I ask you to please interpret me as charitably as possible. I will try to do the same.

You said 0 economists study the issue. I showed you that multiple economists study it. You now also assert that I didn't make you change your mind. Do you still hold that 0 economists study the issue? If you do not, you have changed your mind. If you do still hold that opinion, then I am not sure how to proceed as that would indicate that you are impervious to argumentation.

You are using the number of 10% in two ways:
1.) About 10% of the gender pay gap are unaccounted for and therefore likely to be the result of direct discrimination.
2.) Every group is discriminated against by other people by around 10% of the population.
But these are very different issues. If every group was discriminated against by 10% of the population, the resulting pay differences would (more or less) even out. The does not, which suggests that this a widespread and systematic phenomenon. For some people, although perhaps not you and I grant that it would need to be debated, this might make the problem appear more severe.

Much of your posts just questions the importance of the issue. That is a normative question, which I consider separate from the issue whether the gender pay gap can be partially traced back to discrimination. Here is what I hold in regard to that normative question: I do not want to tell other people that they should not care about the discrimination they experience when I am on the end that profits or at least does not suffer it. It is up to people subjected to this treatment to decide how big of an issue they want to make out of it. I suggest it is a good normative heuristic that one should be wary to question the severity of the problem if one is on the side who is not affected by it. If you are fine discounting discrimination you experience, then that is all well but I would suggest you should not extend that to other people so easily.

(I edited this post to more adequately reflect the position of the previous poster.)

Any system that requires a human to sit there bored for hours, waiting for seconds of action at any moment, is fundamentally flawed. The bipedal ape component is being used out of spec and the blame for that lays with the engineers who designed the system.
I think the main problem is one of social acceptance, that we will see accidents that could easily be prevented by a human operator but at the same time drastically reduce the amount of accidents where from a human perspective, only pure luck or a reflex has saved people before.

As far as I can see, the comments did not (just) assert that adjusted wages were nearly identical. They asserted:

1) That this is not a serious issue and 0 economists study it.

2) That at no point in history was the adjusted wage different between men and women. (This was asserted and not argued for.)

Comments which just asserted that adjusted wages might be nearly identical can still be seen. I agree that this might be debated. The other two opinions appear more extrem and much less plausible, as far as I am concerned.
Much of the time it's too predictable, to the point it's no longer a simulation.

For example, something like Battle Brothers, where the AI tends to attack the least armored ones. You can put a group of poorly armored people on one side of the map and then put heavy damage ones on the other side. The right side draws the combat which gives the left side space to take out the dangerous targets. Humans would spot the tactic straight away. Setting up I exploitation tactics is not so fun for some people.

A worse case scenario are the FIFA games. Every release has some untested exploit. In some, the defenders often push too high and you can score goals from halfway across the field easily. In some, the goalkeeper gets confused when passing the ball right in front of goal. It becomes less a football sim and more how to get formations that optimize exploits.
They would have a hard time testing their cars like this a lot of other places. No wonder they picked Arizona. Around here (I'm in Scandinavia) if a car hits something other than another car it is always the drivers fault, jaywalking pedestrians or not. It is the responsibility of car drivers not to hit softer things - full stop.

This and traffic in Paris are the real tests of self driving cars.
The driver was watching TV on her phone. She might still be charged.

You're right that the bullet point list in your link doesn't have anything that applies to uber, but there is no carve out in the negligent homicide law that says running over jaywalkers is legal. The prosecutor could have looked at:

* whether Uber was warned that having one operator instead of two would be unsafe (they were)
* whether having one operator to monitor the road and the software is inherently unsafe
* whether operators were told that the system would never emergency brake and never warn about needing to brake
* whether Uber reviewed footage to ensure operators were paying attention, whether they knew that operators weren't paying attention etc

I hope all of this will be in the NTSB report.
Backblaze is very lacking in Linux support, unfortunately.

For now, I've decided on pCloud, in addition to an on-site copy on my NAS and a copy on a portable drive that I store at work and update semi-regularly. A couple of rsync scripts take care of everything.

I know it's a cloud storage service and not a an actual proper backup service, but they offer 15 days of rewind as standard, and you can get a full year of rewind as an add-on, which I am considering. That should hopefully protect me from accidental deletes, and give me enough time to restore if my house burns down.

The thing that has really sold me on pCloud is that their Linux client is absolutely amazing. Compared to the barely functional Dropbox client and the non-existent Google Drive client[¤], it is an absolute joy to use. At the moment it's an Ubuntu-only AppImage, but they're working on an improved Electron version.

One additional nice thing is that pCloud is a Swiss company, so their privacy laws (and the GDPR) apply. They do host their servers in the US, so you're not completely free from theoretical NSA/PRISM snooping, but in my case I'm primarily storing my music library. They can go ahead and snoop through the tags of 300+GB of music for The Anarchist's Cookbook or whatever.

[¤]InSync is pretty nice, and I did buy a license for it a while ago, but it's still not as good as pCloud's client.
