I see many comments wondering why does Tesla not recognize stationary objects when it has a forward looking radar.

The radar can't distinguish between overhead signs, trees and things on the side of road. It only track moving things, otherwise there would be too many false positives and the car will keep braking every few minutes. Other Level 2 autonomous systems have the same limitation.

You might recall, Tesla hit a stationary fire truck in Jan [0]. This was caused due to a similar limitation in their software. Tesla was following a car at a slow speed. When that car suddenly moved out of the way to avoid hitting the Fire truck, Tesla AutoPilot accelerated to match the set speed and hit the fire truck. To summarize, if a moving car suddenly moves out of the way, Tesla will almost always hit whatever is stopped further down the lane. They even call this out in their User Manual.

Tesla is hoping that it would be able to get it's Vision capabilities to the point where it would be able figure out obstructions using cameras working in conjunction with the radar. But there is no committed timeline for this.

LIDAR is able to avoid this by using directed LASERs to build a 3d outline of all the surrounding objects. A system relying on LIDAR would have challenges in RAIN and falling snow. However under natural conditions (where most Tesla deaths with Autopilot have occurred - hitting a SEMI from side, hitting the barrier recently), LIDAR would be able to completely avoid the accidents.

However, if and when, Tesla vision capabilities are able to detect obstructions, they might be much cheaper and more effective than LIDAR in all kind of weather condition. Hoping they can get there soon. And I also wish they would fix their marketing to more accurately reflect the capabilities of the driver assist system and stop misleading the public.

I use Dvorak, because it's available whenever multiple keyboard layouts are available.

Be aware of a few things when you switch layouts:

- You will probably lose your facility with Qwerty. If you often type on machines other than your own, then learning Dvorak will be very annoying.

- Many choices of keys are based on their position on the Qwerty keyboard. Two examples that affect programmers are control-Z, control-X, and control-C; and cursor commands in the vi editor.

- Don't expect your typing speed to be much higher than it is under Qwerty. At top speed, typing speed depends on alternating hands, and Qwerty is already moderately good at that.

Good luck with your switch!
It would matter to those of us trying to learn a language, because if another app was better, we could use it instead of duolingo.

At the moment I'm supplementing duolingo by nattering away to my father in French and asking the half-French guy at work how to say various things, but if the app is teaching me things that are plain wrong, I'll have to either find another app or start taking real life classes, which is why it would be useful to know what else is broken.
Hi HN! I've been working on this for the past few weeks. Probably the easiest way to think about it is as a satire along the lines of Useless Ethereum Token, except I'll use it as a way to donate (hopefully lots of) food to food banks rather than just pocket everything.

Feedback welcome!
I've started reading some quantum computing texts, and dabbled a bit with IBM's quantum computing experience, and this is where I get stuck:

I can follow the basics at the level of "gates" or circuits -- a lot of what's out there is essentially quantum assembly language or something of that sort.

But what about interfacing classical and quantum computing? Is the idea that you just run something from start to finish on a quantum computer? Or that you take the output from a classical system and input into a quantum system?

Some of the things I'd be most interested in with a quantum computer seem to require an interface with a classical computer, or at least raise the issue, which generally isn't addressed by these sorts of pieces. It's sort of assumed that you're programming whatever it is you're interested in at the level of machine/assembly code.
Oh, I see now. Thanks!
i m kind of surprised that they have not asked these questions to google. Also:

- Making ads relevant means less ads overall for the user

- It would cost $20 / year and no studies show that users would pay anywhere near that. It reasonable to assume its impractical

- Subscription-premium services rely on a small number of fans to pony up (usually significantly) for the rest of users. afaik facebook does not have such a mass of hardcore, passionate fans.

- More generally there is no evidence that subscription users are happier.
That sounds like a self-created disadvantage of underpaying in a global talent market, rather than an issue with their city.

Uber Is Rapidly Expanding What It Does So You Don’t Buy a Car
Well, no: the printing press didn't ultimately cause that. It enabled easier communication. In fact it arguably democratised mass communication by making it so cheap. It was what was being communicated communicated that caused the strife that led to warfare.

Part of that must have been the "fake news" of its day, like [blood libel][0], but that already existed before the printing press. The other part was a reduced ability to hush up bad things. Addressing that ultimately led to major upheavals of existing power structures, and a lot of bloodshed.

For me, a more worrisome part of the internet is the effect homogenisation, as described by McLuhan in The Gutenberg Man[1]:

> McLuhan studies the emergence of what he calls Gutenberg Man, the subject produced by the change of consciousness wrought by the advent of the printed book. Apropos of his axiom, "The medium is the message," McLuhan argues that technologies are not simply inventions which people employ but are the means by which people are re-invented. The invention of movable type was the decisive moment in the change from a culture in which all the senses partook of a common interplay, to a tyranny of the visual.

> He also argued that the development of the printing press led to the creation of nationalism, dualism, domination of rationalism, automatisation of scientific research, uniformation and standardisation of culture and alienation of individuals.

> Movable type, with its ability to reproduce texts accurately and swiftly, extended the drive toward homogeneity and repeatability already in evidence in the emergence of perspectival art and the exigencies of the single "point of view".

Another interesting tangent is (mis)communication's effect on the evolution of trust, but I don't feel like writing out a whole essay about that, so I'll refer to Nicky Case's "Evolution of Trust" and hope that the connection is obvious[2].

ProseMirror requires a certain willingness to work with strict data flow and immutable data structures, and to cobble together a loose set of small modules before you have something user-friendly, but if you can handle that I think it's a safe bet at this point.

It's interesting to see how many people don't find Duolingo or other apps to be effective learning tools. I spent the last 2 years creating a Thai learning app (that I think of as a 'digital textbook') specifically to address the issues that many people here raise. I won't cite the name since I'm not trying to advertise, just bringing it up as a talking point.

Duolingo does lots of AB testing and found that gamification greatly increased user engagement, but I think that they took it too far and lost the forest in the trees.

Everyone learns differently but in my experience you need to hear or read explanations of the second language in your native tongue and then hear that construction in the second language to reinforce it, because the key is lots of comprehensible input.

Can a complex sentence become comprehensible input with just games? Sure, but if someone can explain how the grammar works in English then you can get to that same point faster and without the guess work. That's my opinion, at least, and so far users are seeming to find it effective since reviews have been largely positive!

I think that serious language students will seek out appropriate apps or textbooks, and Duolingo will be a fun option for people that want a mixture of cognitive exercise and entertainment that may also be useful when they're traveling or interacting in a foreign language.
Gross. I wonder if they were the inspiration for Sliceline or if that was just a happy coincidence?

My sentiment here is that modern JavaScript is _much_ better than its predecessors. The real issue, as it pertains to the web browser, is supporting legacy functionality that's causing drag on the web as a whole.

Reddit is much, much bigger now than Digg ever was; and there’s no viable platform for most to move to. Its communities are decentralized, and moderation is a function of the network, so Reddit as it exists is effectively the only thing holding them together.
This is something i don't get. There's a Papa John near me, on Green Lanes, N4. They charge 18 pounds for a large pizza. On either side of it, there are Turkish restaurants and bakeries where that will buy you an excellent three-course meal with a beer (okay, so the dessert might be the single piece of baklava they throw in at the end). How do they survive?
It seems to me that you are criticizing JS as it were in 2005. There are well known -low overhead- solutions to all the 'problems' you identified.
interesting, i have never had this experience. i can hear the staff, explicitly order what I want, confirm the price with the person and then pick it up paying with card or cash. also, most delivery places have square-type pos services or i just pay cash so i don't give a card over the phone. i love online ordering of products but i think ordering food is a bad experience. Typically my orders are uncomplicated and small though and usually for pickup.

We certainly need the concept of Euclidean space in order to make sense of the phrase "warped space". Fortunately, our "everyday" space is almost Euclidean, so this condition is met. If we lived in a different place in Universe, not sure what our concepts could have been. But I think same applies to just any concept we derive from our observations. E.g., we would never be able to form a notion of ice if we lived near some star. But I can't see how your statement about "real" vs "apparent" follows from here.

I don't get the point of 3rd party browsers on iOS. When Apple doesn't allow vendors to use their own engines. I think Apple should be taken to court over that matter. Safari on iOS is the same as IE on Windows in the early noughts. If Apple could grant Uber privileged API access, i'm sure they can give Mozilla and Google the same permissions to build independent browsers on iOS.

Ask HN: Is Twilio too expensive for you?
Not sure if everyone is in the same boat, I made an app and one part of it allows you to invite your friends via text invite.

My users send about ~500 texts (each text is about 3 segments) and I am spending about $10 every 2 days. Note that I'm a sole developer and not a major company so dont have the funds to keep this up.

Is everyone else sort of in the same boat or have they been able to find some hacks that people are willing to share?

EDIT: Also if anyone knows any developer free offers, etc. that don't need pre-approved phone numbers for Twilio.

We've had a "flying car" for generations. It's called the helicopter. It was even able to land on top of Pan Am's headquarters in NYC.

The problem, of course, is the high level of training required to operate such a vehicle, plus the cost of the vehicle itself.

"Flying car" was never a technical impossibility. It was an economic challenge. "Flying cars" are 50-year long hype.
Quite a few sites have air-gapped networks that consist of employees having two computers (on the same desk), one in the secure network, and one connected to outside. Obviously there's no power isolation.
Agree, and on top of that isn't it interesting that the more successful game movie adaptations are in those areas where the game plot was thin or non-existent. Mortal Kombat and Street Fighter both fit into that - Little to no plot for the games, then movies come along and are probably successful because they're not so constrained.
Articles are more of a regional feature, that is restricted to just a subset of indoeuropean languages. Articles work quite differently in Romance languages than in Germanic languages and even there are outliers like Icelandic which does not use indefinite articles.

In my opinion you could go even further an say that they have an English bias.

Venturing to guess / IMO:

Seems risky for a startup "integrator" (hypothetical company who would solve this) to have their business depend on providing specific integrations per startup + POS system. You would need to keep tabs on any changes ea. of the companies like Slice, GrubHub etc. made from both a service standpoint, and a hardware standpoint, right?

To top it off, it would just be one more layer ontop of this, so how would the company make money? Doesn't seem to solve the Pizza guys problems.

Or perhaps you just generally meant, why hasn't someone built a more modular POS unit that would work with any of these guys. That I have no idea about.
Blockchain and the Law: The Rule of Code
The type system and standard library.
Take the set of all finite C programs without loops or recursive function calls. They (clearly?) halt.

Or: the set of all finite Brainfuck programs that don't contain a `[` or `]` instruction. Those also halt.

Also, see Idris: https://www.idris-lang.org/. It's a language that has dependent types and a totality checker.

A dependent type is a value which depends on another value. For example, the length of an array depends on how many elements there are in the array.

A totality checker means that you must prove that a program that you write halts; otherwise, it fails to compile.

In Idris, if you ever write the equivalent of reduce recursively, you must prove that the recursion will terminate. This is done by noting that the length of an array is dependent on how many elements are in the array, noting that if an array has zero length then reduce will terminate, and noting that every time reduce is called with a non-zero array length it returns reduce called with that array length decremented by one. Then, since repeatedly subtracting one from a positive number eventually reaches zero (at which point the recursion halts) you're guaranteed that your reduce function halts.

EDIT: I guess you are right in the strict sense that languages like Idris aren't Turing complete. But they still can do a huge number of computable and useful things (and most of the things you'd want other languages to do), so I feel like "Turing complete" is mostly a semantic argument here.

People are bound to be disappointed by the effects of GDPR. FB can reasonably claim that its tracking is necessary for its function , because it is. The stuff they ll have to get rid of is marginally profitable anyway. GDPR is not hurting facebook, instead it's legitimizing its model in the eyes of the consumer by giving it the "stamp of EU approval".

How does this compare to Safari's intelligent tracking protection that came out last year? That uses ML and sounds like it's considerably more sophisticated, allowing certain forms of desirable cross-site tracking and not relying on a centralized blocklist.[1]

Crassus was one of the three triumvirs with Pompey and Caesar, but was formerly better known as a a famously unscrupulous and fabulously wealthy business man.

Yes, most certainly. The tie in combination with a comfortable stiff collar compresses the arteries in my neck and prevents me from letting anger and stress rise up into my upper chest area and stay there. In combination with breathing I can dissipate the anxiety to the rest of my body. As well, it does not allow for loud outbursts. Fundamentally, suits and ties alter your posture and behavior patterns to more gentle ones in my experience, while providing needed support.

It's like a G suit allowing me to work in higher atmospheric pressure and stress without damaging my soft internal organs.

I used RescueTime for a while but it has two serious flaws. Firstly, it has no system for scheduling focus time and secondly, it has no system for breaking focus time for a short period. I would constantly find myself terminating the program just to browse the news for 5 minutes and then 90 minutes later wonder why I hadn't done any work. I've submitted both of these ideas as feature requests but I don't have much hope that they will implement them as the app has not changed in several years.
> US crash rates are lower than worldwide rates, so Tesla’s estimate of lives saved worldwide is low.

Road fatalities per 100,000 inhabitants per year (2013, WHO):

UK 2.9
Spain 3.7
Germany 4.3
France 5.1
USA 10.6

Among the rich countries, the US crash rate is one of the worst. With a similar set of vehicles, this rate is very fluctuent, per country and per year. Hint: the problem may not be purely mechanical.

Seriously, would Tesla's autopilot lower the crash rate in the UK? In Thailand? I guess it wouldn't change much in European countries, and any good car would do the same in poor countries.

This is the biggest limitation of duolingo. In most languages, reading is the easiest in the reading/ writing/ listening/ speaking hierarchy[1] - a good way to learn vocab, but learning to cope with the sound of the language at full speed is generally where the biggest challenge lies. I would seriously recommend listening to language learning podcasts over duolingo once you get past a beginner level.
