>removing radar sensors to transition to a camera-based Autopilot system

A few weeks back, I had a terrible experience while using auto pilot. I was driving on a highway (in CA) with autopilot engaged. For the most part, there was a concrete median on the highway. Suddenly, a section came with no concrete median and a new left only turn lane gets added. For whatever reasons, autopilot thought it is a great idea to suddenly move the steering wheel to left while there is oncoming traffic. I immediately took control of the navigation but the car did wobble a bit. My heart kept racing with an adrenaline rush for the next half an hour. I haven't engaged autopilot since then. I can't trust auto pilot anymore- it couldn't deal with a dead-simple scenario of a clearly marked lane getting added.
They are not. Cameras would not be all that useful. See [1] for an estimated system diagram - the main sensor stacks are based on AHRS and GPS.

At delivery. Sounds like a software update waiting. Lane depature would be a pure vision based thing anyway, as radar can't detect lane markings.
Maybe this doesn’t answer your question exactly but I addressed this topic in two blogpost, maybe it helps.

Yes, a decade from now, we'll need an even bigger miracle.
Pretty sure they can have it wiped from the archive as well so if you want to hold on to it better do it somewhere else.
That post is from 2016. From an engineering blog.

Do you really expect, or even want, companies to go back and purge all old engineering blogs which they now disagree with? By calling out an old post as evidence that they are "pro-lidar", you're the one forcing companies to try to curate the public history of their development process.

That's not healthy. Don't do that.
I'm not saying to never use abstractions. There's a balance.
You might want to consider increasing the level of development.

Does that mean you do not care about the truth, as you seem unpersuaded by the fact your missives are found to be hostile?
From what I understand they are transitioning from radar do vision only. The problem was that software engineers missed the deadline.

They will provide that in a software update, it will be just a period of time for new Teslas where the feature is not available. There's no point to wait, since you will eventually get it in update, and if you want the radar you will have to buy used model.

Personally I don't believe vision can replace radar in 100%. In a bad weather vision will be inferior. The argument could be that drivers also only use vision, but other cars do come with radars to supplement driver's vision.
If they're serious about keeping uBlock Origin around, and aren't just stalling while intending to remove what it needs eventually, they should agree to the new API for extensions ASAP... but make uBlock Origin part of the browser, and bring it under their wing (to whatever extent the author's willing for that to happen).

Now that would be an interesting and pro-user move that sets their browser apart from others.

But it might piss off Google a little too much, which is probably why they've not made that or a similar move long before now. One of FF's earliest differentiators, before it was even called Firefox, was a form of ad-blocking, after all (pop-up and pop-under blocking, which at the time mostly meant blocking really annoying ads)
Ultimately it’s all data. The difference between this and lisp is just a bunch of extra characters and noise in the stream.

What is really the meaningful difference between this and an s-expression language? “” and {}, really. It’s a different way to serialize the same thing.

So I’d argue a lot of the criticism is valid.

We do, as an industry, tend to run in circles.
I too call BS. Probably an attempt to draw up interest in the fund, which people will fall for, some will even send crypto to some address in hopes of these 'unbelievable' numbers.

Thanks for the recognition!

I think I get the gist of what this interactive script does and how you propose to extend it. A PR for such a script to go into StGit's contrib directory would be non-controversial. Maybe a little higher bar to have this capability as a first-class StGit command.

We had a preemie baby at 26 weeks in December and feel fortunate our hospital (UCSF) practiced this recommendation. I was surprised they could do kangaroo care that fast (was a few hours after birth), but we did it then and everyday our daughter was in the ICN for 4 months. I'm convinced it made a difference and am sad when I hear about parents who can't do this.

I hope this research helps this become more standard practice.
I apologize that the intro video is so much nicer than my own homemade videos. After paying a pro do to make that first video of a series of a dozen videos explaining the theory behind it, i realized it was going to cost too much, and the money would be better spent on the product itself.

So that video is just part of 1 of 15 parts, and with some support and enthusiasm from people, we can continue the series, because it is o much nicer to watch a professional video with proper British narration. As the great George Bernard Shaw once said, "The United States and Great Britain are two countries separated by a common language."

I hope that people will overlook the homwbrew quality level of the videos, but the language for a spin, because you might like the language a lot. It has a lot of simplifications, and particularly for client/server web apps, where it is much easier to build reliable products.
But isn't this great? You choose the bits of C++ that makes sense for your project and run with it.
Unsurprisingly, there are very few accounts on here of people killing themselves with their own code.
That seems incredibly blatant, given that all the other posts from 2016 are still available.
> Now there are new elements, that is, the fact you have to confront yourself with a lager audience of people and you can see unreal standards.

You nailed it here. Social media heavily rewards extreme outliers.
It's a bit of an apples-and-oranges comparison regarding "as hard as," but the answer to your question is that the rocket uses a combination of GPS for gross aiming followed by radar for fine-grained approach. Vision might be possible but presents challenges radar may not (including that as the rocket gets close to the pad, the back-blast form the exhaust obscures the pad).

As a blind person, I've been thinking a lot about this issue.

I think the best recommendation I can give is to try interacting with the resource as if the image wasn't there. Maybe remove it for a while. Put the information that you're missing in the alt description. If all the information from the image is understandable without seeing it, think decorative images in newspaper articles, set alt to "".

In particular, if the image is a screenshot of a terminal, code or other piece of text, you should put the whole text in the description. In that case, strongly consider omitting the image entirely. When charts are involved, often providing the data in a table next to the chart is the right way to go.

AFAIK, If you have a Tesla already, it will still use Radar. Model S/X also keep Radar. It's being removed from Model 3/Y. I placed an order in early April and I'm kind of miffed that

(1) my delivery was delayed (my original order was supposed to be 4-8 weeks, I'm currently slated for ~10 weeks)

(2) there seems to be supply chain issues, but the company denies it

(3) after not shipping in cars for 2 months, they announce that radar is deprecated, and then suddenly people start taking deliveries.

My biggest fear is that Autopilot won't work as well as the Radar equipped cars and I won't know until 2-3 months down the line which will both affect the value of the car and part of the reason I bought it.
Given that the project is AGPL without any CLA, how do you plan on doing that, if you don't mind me asking? Some sort of portal in front that does this on your behalf?

Asking since I've considered AGPL for my own projects and wanted to monetize via making SAML/SSO "premium" and found that I could not do this easily without CLA
This is a fun project and a cute reinvention of Lisp, as people have already mentioned. I think people are snarky because if this was just a fun project, that would be the end of it. But it seems like JsonLogic is trying to be an actual thing.

And this latter point is why it's just a monumentally terrible idea. I mean.. just look at the Custom Operations wiki[1]. It's honestly just horrible -- horrible -- and may actually even summon Zalgo[2]. This is exactly how we ended up with the XML nightmare of the late 90s/early 2000s. JSON is not meant to be programmable. Please, for the love of all that is holy, stop.

Not sure why you are being downvoted but this is exactly correct. We had, as an industry, been so focused on PCI during this time and TLS was and continues to be the most important aspect of the protective technology. SSL/TLS had already made e-commerce viable in the 90s and its power was well known and being applied for the decade following. Being in 2011 without full ssl for authenticated access was quite bad behavior indeed. Maybe excusable for some low rent bulletin board, but perhaps that is what the commenter was operating. I have no clue.
> As soon as you ignore HTTP constructs, you drop infrastructural benefits and the benefits of particular levels of abstraction reacting to those responses, which are often fully intended to be used.

Can you turn this word salad into a real world example? If it's "you can cache GET requests through a proxy" or something of the sort: Fine, use HTTP GET for that. You don't need to do absolutely everything through RPC. Obviously, a web client using RPC needs to be shipped through HTTP GET, for instance.

> If you didn’t care about any of that you might as well use websockets for everything. And then as soon as you do, you lose out on everything that requires an HTTP request/response.

No. I'm fine with using HTTP for RPC. I'm fine with request/response, it maps well to RPC. What I have a problem with is shoehorning RPC into HTTP verbs and codes for literally no benefit. That's what distinguishes "real world REST" from the more reasonable JSON-RPC.

Try to imagine with all these developments how much performance you can get from vertical scaling.

I bet that many applications don’t need to care about horizontal scaling with all the burdens involved before you outgrow the performance of a ‘single’ box (aka stack overflow)
Per-capita CO2 usage is not really a relevant measure. What matters a lot more is CO2 efficiency.

That can be determined by CO2 per unit of GDP, and CO2 per scientific article.

For example, Pakistan has about the same level of scientific output as Slovakia [1], and 28x the GDP. Pakistan's population is 40x that of Slovakia.

Slovakia's per-capita CO2 output is 7.1 tonnes, vs Pakistan 0.87 tonnes.

But actually, per unit of CO2, Slovakia is substantially more efficient than Pakistan in terms of economic and scientific output: Slovakia is 4.9x more efficient than Pakistan at scientific output per unit of CO2, and 1.8x as efficient for GDP.

You can see similar things across the world when comparing highly efficient Western countries to inefficient 2nd and 3rd world countries.

But its true that Western countries must decarbonise electricity generation and transport, and then support/force others to do the same.

[1] https://www.natureindex.com/country-outputs/generate/All/glo...

This is why cap and trade systems are much less fair than a global carbon tax. Countries, individuals, businesses should be able to emit CO2 if they think that the return is justified against the cost. Meanwhile, low-value and inefficient output should be eliminated as much as possible.

I apologize for the bad writing. I am not a good writer at all, but my programming is quite solid, and i hope you will take it for a spin. It has many nice simplifications, from the reformed Regular Expression syntax, to the automatic dependency checking in layout and refresh (if the model changes values, any part of the visualization that is affected is automatically refreshed).
My comment was referring to the feature itself, I see that the article kinda try to put the things in perspective, but not as strongly and sharply I think should be done.
I’m fully alright with $5 - I saw $10 and immediately thought $5 would be reasonable. If any MDN folks are reading - $10 seems a bit too steep. Especially since this is in US $, it would seemingly put this service out of reach for a lot of people. Perhaps that’s not a concern to the foundation, but works against the principles of the open web in my mind.
I don't think this would be the best thing to do for uBO users. This creates the possibility that the "Firefox internal uBO" could diverge in functionality from the one maintained by gorhill and get neutered by Mozilla managers.

I think it is ultimately necessary due to the incentives at play that the adblocking technology can be delivered by any third party.
It's Turing incomplete. Like HTML.

LISP is, on the other hand, a programming language. It's rather famous for it.

They're are not charging anything to anybody yet, you can get in the waitlist and answer a survey which explicitly asks if you think the price is to high, fair or to low.

Moreover next to the price there's a disclaimer that the "Price is subject to change".

To me it seems that they're just running an experiment to determine what's the price they should put to the service, which seems smart and correct.

This is nonsense. I'd love to, but I haven't literally dedicated my entire life to this specific topic as so many have, I don't believe I am smarter than the average scientist, I don't believe I can find flaws that the average scientist would have found, and I don't have enough time to test every single hypothesis that's accepted by the scientific community and makes its way into my life. I'm just going to do what most scientists do and focus on what I enjoy doing, and if that doesn't result in me completely revolutionizing physics so be it.

This "epistemological DIY" really only works for you if 1) you want to limit yourself to "proving" that apples and feathers fall at the same speed using highschool mechanics or 2) you're extremely arrogant and/or delusional.
> pulled from already-sold vehicles

The radar was pulled from already ordered vehicles. The sale isn't finalized until pickup. I assume they would allow the order to be canceled at least.
a decade? Try a half century.

Everyone (especially the environmental activists) need to come to the realization that we've long passed the point where we have the luxury of being picky over what we replace our fossil fuel (carbon emitting) energy sources with.

While everyone has been arguing about hydroelectric versus nuclear fission versus truly renewable sources versus "just wait for fusion", the energy consumption of humanity has been exponentially growing and satisfying that desire primarily with carbon emitting sources of power.

All options need to be on the table. Mandate solar panels on roofs, mandate battery storage in homes, build utility scale PV and solar thermal plants where it makes sense, build wind farms where it makes sense, get over our fear of fission and build many small, yet passively safe nuclear fission plants and the necessary fuel recycling facilities to reduce the need for spent fuel storage.

Tell anyone who thinks that renewable power sources look ugly to shove it.

Rather than focusing our collective energies on developing more energy generation tech, pivot to figuring out how to sink carbon we've already emitted and use existing generation solutions until the problem is controlled. Then start looking at the future again and offline whatever is obsoleted.
It works quite well for linear network simulations (eg: plugging together black box S-parameters from manufacturer data or extracted from a VNA) and it works reasonably well for filter synthesis. I've never used the harmonic balance simulator or the new planar EM sim though.

Unless Germany uses "public" in wierd way[0][1] the public prosecutor is part of the government. (It's debatable whether they count as part the national goverment, versus just the local/city/whereever government, but the emphasis on "German government" rather than "German government" suggests that's not what you meant.)

No public announcement. They merely have some lidar equipment for testing. I'd be shocked if they haven't already had lidar units for years. After all, you can't compare your approach to lidar if you don't have a lidar unit to compare to.
It isn't. C1 and C2 are two competing optimizing compilers in HotSpot, originally developed by different teams. There is a big difference in compilation time vs code quality between those, though that narrowed as C1 evolved from almost a template-compiler to an SSA-CFG-based compiler. C2 was and is a graph-based, heavily optimizing compiler with a graph coloring register allocation. It's only been in the past 5-10 years or so that both compilers have been used in concert for tiering. Prior to that, they were selected by the "-client" or "-server" options, once at startup.

Sparkplug is designed specifically as a baseline compiler that does not have an IR, in order for maximum compile speed. While the idea of two compilers with different compile time/speed tradeoffs is similar, the constants involved are pretty different.

TurboFan is similar to C2, but Sparkplug is not similar to C1. They don't compete, but cooperate.
You're right. But I would learn any new Java thing in a few minutes because it's explained and documented.

I'm having difficulty compiling a Qt app right now due to complicated and arcane marco directives. The compiler / linker give me no information to work on, and there's no documentation.

It takes 2x as long to develop in C++ it's grinding.

>> While poring over Persian myths and legends for my upcoming novel, Girl, Serpent, Thorn, I was always delightfully surprised whenever I came across a story that sounded familiar to me from my western upbringing.

Here, the author of the article is advertising her book. I see this very often- I'm reading an article on an online publication and the author suddendly and more or less surreptitiously inserts a reference to the latest book they have published and that is currently being sold.

I confess I find this a bit annoying, especially when the subject of the book is unrelated to the subject of the article. I understand that authors must take every opportunity to promote their work, exactly in the same way as everyone else [1].

What I wonder is, is this something that authors are asked to do by agents or publishers? Or is it something an author decides upon him or herself? Is it more common for an author to advertise their recently published books in an article they write, or is it more common not to?
