Neither the JVM nor the CLR were originally designed with dynamic languages in mind.

Thanks to the efforts of IronPython's creator, which eventually joined Microsoft for a while, the Dynamic Language Runtime (DLR) was created.

Eventually the JVM followed suit by investing into the infrastructure that eventually became known as invokedynamic.

Where most JVMs JIT compilers still beat .NET JIT compilers is that they explore more re-optimizations, while .NET JITs tend to only optimize once, but there are plans to at least improve this on RyuJIT.
I would like to rebuttal. If there exists any dynamic application, you need some type of data store to keep all of the records, whether it be a persistent database or simply an in-memory database. So, in my opinion, this is a truthy statement.
The halting problem doesn't say that you can't do a complete analysis of a PARTICULAR program to see if it halts, it just says you can't have a general algorithm that would do this for ALL programs.

Since we are trying to analyze particular programs, you aren't going to be limited by the halting problem.
EdgeDB is very far from being an "ORM in the database". It properly implements an object data model on top of relational model, along with a properly designed query language.
Some of these automation companies are doubtless being run by people with legal backgrounds. I can't imagine all lawyers are interested in preserving the status quo.

A driver of a Tesla car has mentioned in this thread that the car sometimes doesn't register the hands on the wheel.
But those rails are on otherwise off-limit tracks and 'third rail' solutions are notoriously dangerous. This system has the two rails closely spaced side-by-side so it may be a bit safer but in the presence of moisture it could be dangerous too.

It's basically a scaled up version of a slot car track.
Yes, my guess is either public IP or GPS colocation from phone apps, possibly even using the wifi AP name if you both had phones connected. If civilian GPS is good to a few meters, it's easy to look up who lives in that radius.

Developers will need to customize with code for (finger in the air) 20 more years. Eventually we’ll solve this with AI, but talk about a hard problem. It will eventually happen.

Until that point, we need tools that output real applications in ( to start with ) react that allow real time collaboration between design, engineering, qa, product, and project/execs/stakeholders.

I find it fun (enough) and quick enough to use daily to keep my mind thinking in Spanish now and then, but I agree it isn't very effective at allowing me to speak it. I draw a blank whenever trying to converse in Spanish. But, I do find I can read quite a bit more Spanish after a year or so of using Duolingo mostly daily. I only use it for about 10 minutes a day, so I don't expect miracles.

I find the "you are 53% fluent in Spanish" notifications laughable, though. I'm maybe 10% fluent, on a good day, when listening, and about 20% when reading. Though assigning a percentage to fluency is a bit weird anyway.

So...yeah, I think you kinda get out what you put into learning a language, and Duolingo is way closer to putting in "nothing" than it is to putting in "something". One shouldn't expect to get much out, if you're just doing little memory quizzes a couple times a day. But, I can do it without needing a lot of free time, and maybe it'll help some day when I am able to spend a few months in Mexico, so I can immerse myself in the language, to really learn it.

>There's no reason you can't have a 5/5 framework with huge community and support.

There's no law of physics preventing it. I'll give you that.

But between fragmentation of effort, few full-time collaborators, no funding for less interesting work, and other such things, there are many reasons we can't (and don't) have any 5/5 frameworks with huge community and support.
Sorry but I fear the horse has already bolted.

Even if you were able to delete yourself entirely from Facebook. You have been "consumed" already.

Your data was valuable in at least 2 ways:
- Monetize to companies such as Cambridge Analytics.
- Train Facebook's AI models using it.

What was probably happening, was that Facebook was selling your data to other companies so that they can train AI models/make conclusions etc. In addition, Facebook itself is using this data to train AI, make conclusions etc.

Facebook will no longer be able to Monetize to companies as much after this media.

However, and this is the big one, if they use your data to train their models to target individuals (and therefore "take advantage" of them), then they can claim that your data was not used. And then they sell the models, or the results of the models. Its like indirectly selling your data.

This could be a big win for Facebook, because if Facebook does not dish out our information to other companies, it will *uniquely" be placed to provide such services to the rest of the world.

And this will be almost impossible to regulate.
Why angry? In my experience most understand the problem well, but feel too dependent on FB to ditch it for good.

Mad Max isn't anarchy, it's a centralized authoritarian dictatorship. What you're talking about where you want me to suggest a definition of "the game," how it's played, how to win, etc. is closer to Mad Max.

With regards to healthcare, the best system is one in which each individual person has autonomy over themselves. Each will have its own desires: making money, saving money, receiving treatment, etc. The "system" emerges from the accumulation of human desires and abilities. I can't tell you exactly what it looks like because I can't pretend to know what everyone will want, nor can I tell you what is best for everyone. They are best left to determine that themselves.

So far in this thread, there are several comments that could be the grounds for substantive discussion, but don't bother offering the substance. For example: Why does jonbarker recommend Anki for going deeper than "complete beginner"? What does zealsham mean by Duolingo lacking a "structural syllabus" and why is that problematic?

The conversations can be a very valuable part of HN, but not if most comments are at the level of "I still find their spaced repetition lacking" with only the tiniest bit of elaboration. Hopefully I'm not out of place in encouraging something more substantive.
Yeah, that definitely motivates me :) Thanks!
Thanks for the interest! We'll release a technology preview (along with the source code) in just a few weeks.
I had thought much the same before, focusing on the theatrics, until I started working with a startup with lawyers and for lawyers. There was also a family matter that deeply affected my wife and I. My wife worked with a lawyer to regain custody of her child back from a screwed up situation. The product I was helping to write was related to what was affecting my family.

There is a lot of thought put into policy and governance -- of what to do when the group of people are too large for everyone to know each other. Further, when I was introduced to the book Crucial Conversation, I realized that resolving conflicts among people without shared narrative does not have to happen this way. The book talks quite a bit about the typical reactions to crucial conversations -- violence and silence. That's exactly what I keep seeing when I see people talk about politics now, in the Trump era.

So I disagree: the theatrics and narrative building is not the backbone of politics, though I will agree that those theatrics and narrative building is one of the core tools people typically use to gain and wield political power. There's the tool -- which may have alternatives -- and then there is what you are trying to accomplish with that tool.

And thus, I come back to: How much of the political theater is affected by this? Isn't there a way for people to be inclusive and respectful of individuals?
Unfortunately, as long as consumers can't be uniformly and universally trusted, there's but a market and a compelling, morally-acceptable use case for consumer tracking and reporting in that regard. So if what Facebook doesn't differ from consumer reporting in some other way, I don't see a compelling argument to toss it for the same reason I don't see a compelling argument to toss, say, return fraud tracking.
The ranks of wealthy people are not chosen by a committee who get to vet them based on desirable traits. You either have wealth or you do not. The wealth either belongs to you or it does not.
Apparently they tested just that -

Säll said: “There is no electricity on the surface. There are two tracks, just like an outlet in the wall. Five or six centimetres down is where the electricity is. But if you flood the road with salt water then we have found that the electricity level at the surface is just one volt. You could walk on it barefoot.”

They also mentioned they turn off each segment if there is not a car on it. Each segment is 50 meters.

From a comment without any substance, this is rich.

>And 5/5 is 1 genius

Besides, the ad-hominem, I was referring to a quality rating (as in "5 out of 5 stars") not a generic ratio.

But even at that, 5/5 (1) is bigger than 3/5 (0.6), so the point remains, either way you look at it, Erdos.

If it's possible to do a complete analysis of any particular program, shouldn't it follow that it's possible to do a complete analysis of all programs?

If only a subset of all programs can be completely analyzed as particular programs, what are the boundaries of that set?
Correct, but the rest of the paragraph sort of gives that impression (at least to me) by mentioning how language compilers are usually written in a more primitive language, like the Go compiler being written in C then later rewritten in Go.

IMHO that sort of blurred the line between the platform and language in the article...rewriting the Go compiler in Go sort of makes sense, but I don't see why this was a good comparison to the .NET ecosystem. Rewriting the CLR JIT in C# isn't making it "self-hosting" as its not language specific.

Does that make sense?

It is the same with mathematics and most sciences. Learn 1000 things so you know when to use 10 of them.

It is impossible to know all the uses for complex things without actually understanding them.

In a handrolled assembly loop, the array pointer can be the iterator itself. In fact, this would be the ideal to compare the linked list version to, as the linked list would not have any kind of incremented iterator except for the pointer itself..

Agreed; missing from the list is which entities have me in their list of contacts. This is of course available to Facebook. Of course they can't give me this data because they don't have consent from the other party, but still at least a nod to the missing data would be appropriate.
Sure, but most of it is in Java, .NET and such.

The rest of it could hide any number of dragons (and be written in any kind of legacy, nightmarish, and/or proprietary tools and languages), so it's not much of a proof of widespread bad C "goto" abuse.

Let's make a better criterion: how many of the top 200 C projects in GitHub suffer from "spaghetti goto" abuse? How many of all the C projects in GitHub?
Yes, I did read the article, otherwise I would not have been able to write what I did, note that the title says nothing about how the electrodes from the car connect to the road. So you could have known that I had read the article. Yes, the article addresses it, no, the article does not address it in a way that gives me a good feeling about the safety of this system in the presence of moisture. It really doesn't take a lot of power to kill a person and even though you can ground-fault-protect the crap out of a setup like this the fact is that such measures can fail and if you start deploying it en-masse in a hostile environment they will fail in large enough numbers that it will not longer be safe.

Note how industrial power is hardly ever ground fault protected because the leakage currents in the standard setup are too high already to reliably detect a ground fault.

In other words: if the system delivers enough power to electrical cars to meaningfully affect their state of charge there is inherent danger.
I always see this framed as between Tesla and the driver of whatever vehicle has crashed. That framing is irresponsible and should stop.

When a Tesla owner chooses to use autopilot, it has a potential impact on other drivers and pedestrians around them - not just driver. Part of the reason we have regulations about seatbelts and airbags isn't just that they keep passengers safe its that they make crashes safer for others on the roads. With a human driver, others are on the same page and can do things like make eye contact or assess the behavior of another driver. In an accident, they can hold that driver responsible. It is not other drivers nor pedestrians role to accept the risk for a Tesla driver wh omay or may not understand the specific nuances of a specific software patch. Thats why we regulate vehicles and license drivers. As a society we choose to do that because the organizations that do so are an enormous efficienty and capability improvement in assessment as compared to asking each individual driver to do the same.

I don't really want to make this political but frankly the seeming lack of understanding strikes me as very software/app/tech mindset and very much a product of the intermingled libertarian leanings. Cars are not software.
My observation from using Duolingo (Spanish) was similar to this. My theory was that there spaced repetition was simply based topic and then once a topic was chosen it then decided what words to test you on. This is crude, simplistic and ineffective (IMHO). Like you say, there are words you see rarely.

Also, certain topics end up reinforcing earlier topics. I lost count of the number of times that the stupid "algorithm" would make me go through the exercise of translating "no, nada". At some point, don't I just know this?

Additionally, when you have topics that aren't "gold", it simply selects the first non-gold one to repeat. This can mean that a bunch of stuff at the bottom of the tree gets rusty because you don't get to it while you end up redoing stuff you know backwards.

I made this observation in the forums but couldn't really get any traction on the issue.

At some point they also introduced the stupid heart system, which was pretty much my trigger for just abandoning the whole thing.

Also, I'm really not sure how much this format actually works. Like having completed the Spanish tree, I'm honestly not sure if I really remember anything more than a small fraction of it.

Why is this considered "the world's first electrified road for charging vehicles"? Compared to https://www.wired.com/2013/08/induction-charged-buses/ for example. Does induction based charging not count as electrified? Is it that the Korean one was for their buses only, not general passenger cars?

Tesla's progress in ramping up production for the Model 3 could charitably be described as "rocky," and there's been a steady drumbeat of news stories over the last couple of months saying Tesla's financials don't look great either.
