> Raft doesn't deal with the faults

I'm not sure what this means. The Raft paper explicitly states that Raft is a fault-tolerant system -- and by definition this means it deals with faults. To quote the paper:

"Replicated state machines are used to solve a variety of fault tolerance problems in distributed systems."

Raft is a type of replicated state machine. To say that "Raft doesn't deal with faults" is not correct. Perhaps you mean that there is other work to be done to take the fault tolerance offered by Raft and build a functioning application, and a system that will stay up in the real world -- and deal with an even wider range of faults. That I definitely agree with.
I've got to take issue with you there. Tesla Engineering knows better than anybody what updates they did and how often they update etc.

Tesla PR knows nothing about what updates the engineering team did. At least some people in Tesla PR probably don't even know the cars update their software regularly.

It's bad practice for them to speak out of turn, but I can absolutely see the PR team not having a good grasp of what really indicates safety and their job is to just put out the best numbers possible.
> Previous autopilot versions didn't do this. 10.4 and 12 do this 90% of the time. I didn't post it until I got .12 and it did it a few times in case it was a bug in 10.4.

This is why the idea of self-updating cars terrifies me. I'd never allow autopatching on a production server - Why would I allow it on hardware I'm betting my life on?
What makes you think this is a non-story? It is yet another example of a culture that feeds on lack of empathy and respect of peoples lives.

Yes, it is boring, yes it is repetitive. And it will continue to be that way until facebook gains a shred of decency. But I guess that we should just forgive and ignore because there are too may of them?

Maybe you are not the target of these stories, the public at large do feel that they are surprising and shocking.
> I think this is a bit of an exaggeration. As long as the driver keeps paying attention and uses it as a driving aid, not a driver replacement, everything is fine. It's the moment that people start relying on it doing something that it wasn't built for, that the problems arise.

I think this is a bit too optimistic. People will start relying on it to be an autopilot. I think most people see this as the desired result: a car that can drive itself. Do you really think anyone wants "a car that will drive itself while you are paying full attention to every detail"? Otherwise, what is a driver really gaining from this? They're still expected to pay just as much attention (if not more) and I'd bet it's even more boring than regular driving (no interaction from the driver means it's like the world's most boring VR movie)

Humans are not machines, we love to find the lazy/easy way and we love to do things rather than stare at the road, eventually people will grow complacent (hopefully not before the tech is up-to-snuff).

The point is that you don't hand out the license trivially. Yes, spacex is just discussing this in the context of a glorified webcam, but webcasts aren't their only business. Such a license needs to consider the whole business. Now the NOAA perhaps should consider a type of limited license, but they can't assume the only imagery technology spacex is interested in is webcams.

I believe the parent is talking about small overlap crash?

Small Overlap tests: this is where only a small portion of the car's structure strikes an object such as a pole or a tree, or if a car were to clip another car. This is the most demanding test because it loads the most force onto the structure of the car at any given speed. These are usually conducted at 15-20% of the front vehicle structure.[1]

Modern cars are surprisingly good at small over crash tests, see this video someone linked on HN a few days ago https://www.youtube.com/watch?v=DHlj8-JcWa8

I just don't understand the willingness people have to put their lives in the hands of unproven technology like this. I mean, I don't even trust regular old cruise control in my cars and I keep my finger on the "cancel" button whenever I use it during long highway drives.
@levelsio also published a book on the subject recently.

The title for this HN item is misleading. The article was written by James Shore and Diana Larsen, and they should be credited for that.

All manufacturers sell semi-autonomously driving cars. At a minimum cruise control, but more advanced features like e.g. https://www.toyota.com/safety-sense/

Tesla sells a feature set that sounds slightly more advanced on paper, but in practice the benefits are pretty comparable.
It would be even better if BrandonM also commented here ;)

Last I saw there was a minimum fine of x million Euros.

Edit: had to verify. It seems a bit more reasonable: """Article 83 of the General Data Protection Regulation provides details of the administrative fines. There are two tiers of fines. The first is up to €10 million or 2% of annual global turnover of the previous year, whichever is higher. The second is up to €20 million or 4% of annual turnover of the previous year, whichever is higher.""" - https://www.gdpr.associates/what-is-gdpr/understanding-gdpr-...

This license is probably in place to cover situations where high resolution cameras in commercial satellites could compete with military surveillance ones.
Consumer protection effectively does change if its enforceability changes. If a system's security is improved (or at least the security theatre is improved), it's easier to disbelieve victims of fraud, and even accuse them themselves of fraud. This is especially true when existing known vulnerabilities are closed, and fraudsters begin using new vulnerabilities.

To use an analogy, it would be like if you improve the reliability of a product you make, then start saying those who RMA your product must have damaged or mishandled it for it to be broken, and deny them their warranty.
The funny thing is, Emacs does a lot of those things better than the dedicated applications. It seems that anything that involves text or textual representations can be done in Emacs better, and every feature you import composes with each other nicely and consistently, leading to more speed and more power.
I think Tesla is losing out here by calling what is little more than adaptive cruise control plus lanekeeping "autopilot." Adaptive cruise control + lanekeeping + collision avoidance is available on a ton of cars now, even economy cars, and it works great. I regularly make a ~200 mile drive on the Honda system and it is 100% the whole way. But when you sell it as Autopilot instead of driver assist, people have much higher expectations and blame your car rather than the driver - though there very well could be serious problems with the Tesla implementation.

Lanekeeping is actually very nice. The system in Teslas and most (all?) others do require you to keep your hands on the wheel and pay attention, but having to constantly manually steer the car is much more fatiguing than you would think. It's really annoying to drive cars without lanekeeping now.
The XPS 2-in-1 has also dropped all useful (in the present) ports, reduced the keyboard travel, and messed up the arrow key area on their keyboards.

I'm worried that the XPS line is trying too hard to be a MacBook; what if they want to make next year's model even thinner?

Their "classic" XPS 15 looks fantastic, but I've read too many complaints about reliability and coil whine. I hope they keep iterating on it for a few more years.
They shouldn't market it as "autopilot"
It varies. I don't have anything like 16. But I have a couple of cards with specific reward benefits that I pay for plus a number of free ones for benefit and other reasons.

Not sure which course you took, but my Certified Solutions Architect wasn't that bad. He obviously has a platform he promotes but to me it was only about 10% or less of the actual course.
Yes, but the volume in kbps is tiny.
The problem is autopilot actively engages you even less than highway driving. I argue this exacerbates some of the problems that cause humans to checkout.

I don't know what the answer is but it feels like GM's super cruise does a more adequate job of acknowledging the realistic limits of the technology and explicitly white lists roads where the technology is available for use.

I personally think that without some sort of sensors or beacons in the road, autonomous driving via camera and LIDAR sesnors is ever going to be good enough to achieve level 5 autonomous operation.
OK, but there are clearly cases where the autopilot gets into trouble, and the human needs to take control again quickly. The human driver absolutely cannot doze off.

Now, I realise people in old-fashioned non-autopilot cars can and do doze off, and that's very dangerous. But it's not clear to me how the autopilot improves that situation. Relying on the autopilot actually encourages you to doze off.

We already have simple remedies like "pull over if you feel tired" and "never ever pick up your phone while driving (or you'll lose your licence)"
The hubristic disconnect between the technical minded people here on HN and the general masses of users is startling and indicative of the problem.
Agreed. I really hate that Tesla named the feature "autopilot" as it gives the impression of being fully automatic (yes, I realize boat and airline "autopilots" aren't fully automatic - that is likely lot on most consumers).

My VW has Adaptive Cruise Control (ACC) which does the normal cruise control, plus basic distance keeping (with an alarm if the closing speed changes dangerously).

My parents' Subarus have ACC plus lane-keeping. The car will only do so much correction, plus alarms.

These seem like much better solutions, given the current state of driving "AI".
The are two very real issues/threats here.

the first being people are being put in harms way by either false sense of trust invoked by the name or the mixed messages from Tesla

the second is that if the first is left unchecked Tesla could single handily set back Autonomous driving for all by souring public and government opinion.

it needs a new name that aligns better with what it can do. it could be a safety system which gently corrects a driver and takes over in an obvious emergency internal or external. as it stands now it is just dangerous
Which AWS certification? I just did acloud guru courses as well and got my certified solutions architect associate.
There is https://docs.microsoft.com/en-us/office/dev/add-ins/excel/ex... if you wanted to port it to JavaScript! It’s a very weird and badly documented async API, but it is possible to lift out the data and, say, use https://github.com/kripken/sql.js . If you’ve got something good going in VSTO though, I wouldn’t waste time trying to port it. Most people doing corporate reporting are indeed doing it on Windows anyways, I’d imagine.
Everyone's afraid that AI will become too smart and take over the world. They should be afraid that it's too dumb and already has.
Guess what computers excel at? Driving consistently
on consistent highways.

Watching the video, would you say the computer was excelling, or that the road was radically unusual? I wouldn't.
When I was a kid there was a cartoon where a truck painting a white line in the middle of the road, drove off a cliff for some reason (and therefore, so did the line).

The punchline was that all the other cars also fell off the cliff because they were following the line instead of looking at the road.

It's crazy to think, that's where we are now with so-called self-driving cars.
So SpaceX either knew about the regulation and ignored it (without clarifying with the regulatory body if it applied to them), or didn't know about the regulation. I'm not sure which is worse but both are bad.

I think SpaceX is doing cool, groundbreaking stuff, but they should be following the rules.
It's not any different than the situation with bad human drivers, but anyone on the same road is exposed to these systems.
The beauty of it is cases like Google's. They have this bizarre 2FA security-theater Google Authenticator thing, but then nearly force everyone to have their phonenumber as a "backup device".

Guess what the send you when you forget your 2FA or password? Yep, an SMS. So out the door goes the whole point of 2FA. Your three factors (account name / email address + password + Google Authenticator) have now been reduced to one factor: your email address.

I can rent a mobile tower in Malaysia or some other asian country, advertise your phonenumber as roaming there for about €10/h and start intercepting all your shit. Or just get your telco's inept service dept to forward your number somewhere else.

Lessons here:

1. Even the giants get it wrong.
2. There is no security anywhere in the tech world. Literally everything is broken. Your electronic car locks / starter system, your phone, your internet, everything is horribly horribly horribly broken beyond any imagining, even for hyper-tech savvy people.
3. Remove your phonenumber as a backup device from your google account and never use it as a backup device every again.

Hi, I'm a recent graduate looking for an entry-level position. My thesis was to write the driver for a job pipeline running on an FPGA, and I'm looking to continue with systems programming or other interesting back-end work.
Agree, it’s been always surprising to me that companies don’t just release sources after say 10 years.

I wish for Fallout 1 and 2 sources. I think there would be strong community interest in hacking it.
humans at least are aware that they made a mistake and can avoid collision. Tesla makes no mistake, tesla has no idea whats going on so you cannot call it a mistake. Its not a bug, its a feature.
Or just XQL? It could be branded as eXcel Query Language.
Development methodologies have been turned into weapons against the employees.

That's how the average manager sees it, plain and simple. Everything else is just fluff and cake decoration sprinkled on top.

It's a hip brand that justifies things that would otherwise be hard sells.

Want to drag people into daily meetings where they take turn in telling everyone what they did yesterday and what they are going to do today? ... "Agile! shiny ... daily standup" now it's acceptable.

Perverse incentives mean businesses devour and bastardise any given methodology into a leverage for themselves and a stick to beat others with.

Methodologies were partially meant to empower the employees but that didn't last long.

Consultants may ponder about nuances and details.

The businesses and managers who never see beyond the next quarter just see it as a socially acceptable brand to exert power.
Personally I hate cruise control. I prefer to be actively engaged when driving. Either I am driving 100% or I am not at all, there is absolutely no middle ground in my opinion
I like is the fact the game is written in fixed point maths.

It's easy to forget that when this game was written computers either a) didn't have an FPU or b) the FPU was so slow it was useless.

I bet if I searched through the code long enough I'd find a sin/cos lookup table too :)
To directly answer your question: people buy autopilot so they can check their phone while commuting down the freeway to work. I was talking to a group of people about the difficulties of commuting in the Santa Clara Valley, and one guy shrugged and said, "just get a Tesla, move to the left lane, and manage email until you get to work".
For some, it probably shaped it more than they knew. The Rankin-Bass animations (The Hobbit, The Last Unicorn, etc) was outsourced to a studio named Topcraft.

> The studio went bankrupt and dissolved in June 15, 1985 essentially splitting the studio in half. Hayao Miyazaki, Toshio Suzuki and Isao Takahata bought the studio when laying off most of its animation staff and changed its name to Studio Ghibli.
> this is really about static vs dynamic linkage, regardless of the mechanism you use to effect run or build time binding of dependencies.

No. Distributions have been ensuring security for 20+ years by:

- using dynamic linking

- unbundling/unvendoring dependencies into dedicated packages

- having a security team that updates vulnerable packages in a timely manner

- having tools to update vulnerable packages without having to rebuild/reinstall/reconfigure the world

This is what happens when you don't do that:

Beacons is a great idea -- have some standardized beacon system, and a public map of autopilot-approved roads.

Following the beacons safely would be a vastly easier problem than trying to completely replace a human driver in all situations, but it would still give you about 90% of the benefits.
Your CSA associate cert? I recommend taking notes and going through your test exam multiple times and looking up correct answers for everything you got wrong. It's harder than you may think and although i find knowing specific tidbits about AWS services quite meaningless it's still a measure of some sort. Didnt even raise my salary, hah. I had 5 pages of AWS notes of sorts after i had finished cramming.
The ability to discern when the car needs to stop for a stationary object right in front of it needs to be an ironclad requirement for self-driving.

It seems that sophisticated LIDAR is currently the best way to achieve this, but LIDAR is expensive. So companies like Uber and Tesla skimp on the LIDAR, and build self-driving cars that can more or less follow lanes but plow right into obstacles? Whoa.

The feasibility of widespread "self-driving" tech is going to advance only as the cost of LIDAR falls.

I've rented a model S for a weekend and drove about 1 000 kilometers in it.

Naturally, I tried the auto pilot feature on a highway but I wasn't to impressed. There is a major "bump" (negative G-forces), and the car tried to swirl into the other lane (this was within the first 40 minutes of my drive), and that made me distrust the auto steering feature.

As I think you're onto, I DO feel that auto pilot is the future, but we're not there yet - let's improve the existing life saving features (and not disconnect them, looking at you, Uber).
Indeed. I was being overly rhetorical :)

I assume they have a test suite that allows them to run 1000s of situations on the latest version of software to see if it crashes/almost crashes on any of them.

If so, it seems like it would be fairly easy to add this situation to the corpus... especially if they are recording data from their cars live.

They should have 100 people going out there and recording this lane split situation into their test data ASAP.
It adds a whole new level of frightening to the term breaking change.
Hi, Mijndert here, the writer of the article. Thanks for sharing your insights. I agree I glossed over a few topics. I will expand on these from here on out and go into more detail on some of the points you touched on.
I'm pretty sure Jobs wasn't designing PCB boards or touch screens himself; he had whole team of people doing it for him.

I think you missed my point.

Except it gets reported back to HQ and like with airline accidents, the systems are updated across-the-board so that the risk of future occurrences is greatly reduced.

So instead of a single human learning "gee, shouldn't do that again", 100k+ vehicles learn about it.
Loving the analogy :D but (and excuse my ignorance), but in NFL those rules don't allow that, where as it appears the markets do have these mechanisms to allow it?
