I'm sorry but this just total nonsense.

They could make lots of profits if they weren't growing 30-50% a year reinvesting massively, paying massive bonus to Musk that he only gets based on massive growth.

They have 18+ billion of cash on balance and could easily raise much more if they needed too.

They have upper tier operational margin and extremely good per unit margin.

> EVs are commodities.

EV are only 2% of global vehicle sales and Tesla is clearly the leader and is growing very fast still.

Go actually read about the limited availability of lithium, nickel and chemical processing. Not that there is not enough in the ground but scaling the supply chain to 100% EV will be massively challenging and that is before you even get into cell manufacturing.

> their profit is entirely due to credits?

I really don't understand why people are so utterly obsessed with this one part of Tesla income stream. Their margin are all clearly still fine and their growth is amazing even if you subtract profits.

Sure in the last couple quarter if you assume no credits at all then Tesla would just be an amazing growth company that doesn't make a profit but it wouldn't actually fundamentally change the bull case for Tesla all that much.

Tesla is by a huge margin the dominate EV player in US, EU and China by revenue generated while they have good margin (other car makers don't break out their margin for their EV business btw) and there is no evidence what so ever that their growth will stop, there is actually a huge amount of evidence that the opposite is the case.

I know some people don't like Tesla, that fine but people who still treat Tesla like this tiny startup that is just about to go bust unless they deliver on some feature X is simply not the case.

China says nobody was sick.

It's quite simple, the US should release the names of those who were sick.

I'm not talking about running general purpose CPUs. I'm talking about the most high end specialized silicon we have. Throw the best TPUs ever made at the problem and you still won't get anywhere even remotely close to what the squishy pink meat can do.

The power gap is so huge, our software simply must be inadequate. We're talking about a power gap wider than the gap between my toaster oven and the Saturn V.
Greta Thunberg was a 16yo with no background in science, why was she given the world stage? Who paid for that anyhow?

Bill Nye has no background in science, he was a mechanical engineer become actor. Why would you listen to him?

AOC has no background in anything scientific or engineering or public policy... do you get the point yet?

People listen to who they want to believe in.

I would think that would be an easy thing for HN's admins to detect. I hope they are doing so and cancel out any such downvotes.
Hopefully people will start to realize that questioning norms and diversity of thought should be accepted on social media. Silencing and suppression of questions and thought by media is rampant and occurs here on Hacker News as well.

The population as a whole (especially under the age of 30) feels like a bunch of sheep to me these days. They can't think freely, question things, or ask hard questions. They all just want to fit in. Ideology that doesn't align with bit tech and social media agendas is quickly dismissed as right-wing idiocracy.
Good news everyone!

> We need to reduce the number of humans on Earth.

I'm happy to point out that this is not the case.

We're already peak child and the next two billion will not come from population growth but from population replacement[0] (Thanks, Hans. RIP, I loved you), where children replace the people in previous cohorts that never made it to reproductive age.

The number of humans will reduce rather drastically in the next fifty years. Many countries on earth already and most countries on earth in about twenty years will have problems maintaining their population as it is. Fertility has been dropping all over the globe, with a few exceptions in sub-Saharan Africa.

No, really. There's nothing we can do about the people we already have and there are barely any new babies arriving.

What we do need to worry about is population migrations. We need to make it easier for people to migrate. We need to set up political and social infrastructure to welcome people from places that climate change has made inhospitable.

Since most of the world will be suffering from over aging and from a lack of births, these migrants will be dearly needed.

So, no need to talk about birth control, let's talk about immigration reform instead!

Nobody is preventing you. Who is preventing you? There’s no government action here. You buy the phone or you buy a librephone. Let’s leave the government out altogether.

You’re the one pushing for some kind of regulation against free agents interacting. No need to contact the federals on this.

The media is so disappointing these days. A lot of people don't remember this, but the mainstream media outlets were actually playing down the coronavirus pandemic at the start. Then they attacked the travel ban to China. Then did a complete U-turn. Pelosi was dancing in the streets of Chinatown San Francisco to prove how safe and not racist she is. It seemed like they hated Trump and would fight anything he did.

No shit she was prepared for that? That's her job? How is that a bad thing? Oh, because your gotcha question didn't work. Ridiculous.
I understand you wish that to be true in the UAE, but that's not the law.

Here's a case from Nov 2016: https://www.independent.co.uk/news/uk/home-news/british-woma...

Some quotes from the article:

> It’s against the law to live together, or to share the same hotel room, with someone of the opposite sex to whom you aren’t married or closely related

> The burden of proof required for rape under the UAE’s interpretation of sharia law – a confession from the rapist or witness statements from four adult men – means that cases that reach court are heavily skewed in the defendant’s favour and are frequently dismissed or turned around to prosecute the alleged victim.

> Ms Stirling said the UAE has a long history of penalising rape victims. “We have been involved with several cases in the past where this has happened, and we work with the lawyers and families and have campaigned to change attitudes in the police and judiciary,” she added.

> “The horrible case at hand shows that it is still not safe for victims to report these crimes to the police without the risk of suffering a double punishment.”
Check out Ned Nikolov's work. The greenhouse gas model is as flimsy as the Flat Earth. Reading his stuff reminded me of Leah Remini talking about learning of Xenu and the associated lore in Scientology. I can't believe I was so brainwashed.

This is mediated by the fact that SAT basically measures g, g is heritable, and g predicts income level. It does not imply SAT unfairly favors rich people.
Yup. One of the first 32-bit programs many people owned was Doom.
Author here: we do have various numbers collected here, with varying levels of "I'm sure enough about these numbers to share them in a public blog post".

Compile time is on roughly the same order of magnitude as Ignition compilation (just AST to bytecode, so excluding parsing), and roughly two to three orders of magnitude faster that TurboFan. The relative performance to the interpreter, as the sibling comments point out, varies _wildly_ by workload, but around 4x is probably a decent approximation for something not entirely dominated by property loads.

About 5 years ago I met these guys when I was building a smart city startup in NYC. We helped cities unify their data from various vendors they use, one of the data streams was a computerized 911 dispatch. Vigilante (at the time) was interested in getting access to the 911 dispatch API. I had a long conversation with them and they couldn't understand/answer any difficult questions - I was extremely uncomfortable- nevertheless, I took it to a few cities and floated the idea of allowing them to tap in, some cities seemed marginally interested but wanted to provide access to the data with a 10+ minute delay on it so as to prevent ambulance chasing/vigilantism... of course this was useless to them, they needed real time, so they stuck to transcribing 911 dispatch from the radio waves.

Given they couldn't/wouldn't ask basic questions about safety, I'm not at all surprised this is happening.
I loved The Very Hungry Caterpillar as a kid, and now read it to my 6 month old before bed. He loves it too, smiling while playing with the little mini pages and me poking his finger into the holes as the caterpillar chomps through his feast. Precious moments.

It doesn't actually need full general AI, but it does need to know and understand all of the roads in its "service area". IMHO the real solution will be building a database of roads (and lanes, speed limits, traffic lights, stop signs, etc).

BTW, the average driver gets in a crash every 18 years. The best humans aren't perfect either, and a self-driving car really only needs to be better than the worst humans to be an improvement (although it will have to be much better to succeed).
> Lots of tiny functions kills readability.

I've heard this argument a lot, and I've found generally there's another problem that causes lack of readability than the small functions.

>Assuming your language supports this. C++ notably doesn't, especially in the cases where you'd produce such small functions - inside a single translation unit, in an anonymous namespace, where enforcing "caller before callee" order would require you to forward-declare everything up front. Which is work, and more lines of code.

Here though you're kind of used to reading code upwards though, so flip the depth first and make it depth last (or take the hit on the forward declarations. If you've got more than you can handle of these, your classes are probably too complex regardless (i.e. doing input, parsing, transformation, and output in the same method).

> quite often a properly descriptive name would be 100+ characters long

Generally if this is the case, then the containing class / module / block / ? is too big. Not a problem of small methods, problem is at a higher level.

> Explicit pre/post conditions in each method

I should have been more explicit here - what I meant is that you know that in the first method, that only the first 3 variables matter, and those variables / parameters are not modified / relevant to the rest of the method. Even without specifically coding pre/post-cons, you get a better feel for the intended isolation of each block. You fall into a pattern of writing code that is simple to reason about. Paired with pure methods / immutable variables, this tends to (IMO) generate easily scannable code. Code that looks like it does what it does, rather than code that requires reading every line to understand.

Facebook, Twitter, and much of the news media have been in the service of CCP as part of an influence operation and suppression of dissent.

There needs to be an investigation. The people involved in these decisions need to be put under oath and testify how they came to the decision to ban users. Emails and messages should be subpoenaed to see if there was illegal coordination across services. There needs to be an complete investigation if any of the people involved were being influenced by or were agents of the CCP.
So much bullshit. Penises are literally the favorite thing of many men across human history to draw, in all shapes and sizes, any preferably the most public location. It was even a plot point of a major movie a few years ago.

Also, a lot of home construction in the US is single family and this type of construction is by and large mostly wood.

Concrete is used as a base for apartment (like four or five over two) but wood still makes up the majority, and there aren’t a whole lot of residential projects in the country built as massive concrete tower blocks outside of some specific regions.
How about representing the logic as a JavaScript expression:

OK, so that second citation is very odd:

- It's in a journal called "Temperature" with the mandate: "Temperature publishes papers related to interactions between living matter and temperature, with focus on the medical physiology of body temperature regulation." All the other papers fit this mandate, i.e., they're on physiology.

- It's marked as an editorial, not a peer-reviewed article. There are no co-authors.

I have no idea why or how this got published! It's very weird, why would one even submit such an article to an irrelevant journal?
I am having a difficult time wading through current "shortage" links to find the original information. However, here is the gist.

- The inventory of raw timber ( the type you see in log yards ) has grown too large.

- Lumber mills are lowering the amount they will pay for raw timber as a result. As well as the rest of the end lumber market.

- This causes timber companies profit per foot to drop.

- The timber companies decide to "export" raw timber overseas at a loss.

- This in turn raises the rate the Lumber mills and Lumber consumers pay out pacing the original loss on "exported" timber.

It is important to also note, most of this timber came from public lands to begin with.

The overall point is OUR resources were exported at a loss so OUR prices would increase. Forests are part of the wealth of our country. Letting a timber company send it overseas to increase domestic timber prices should be illegal.
Right on, this might be a great move.

Though radar is a powerful technology. Two camera's with the right depth sensing software behind it could do a lot. What about light source though? Camera's with great light sources provide a super powerful technology, but what are you going to do in the dark/rain? Then again, camera's are cheaper and can do better in some conditions with (semi)reflective surfaces. It's all up in the air, but making sense of the world in a moving object with constantly changing scenery and multiple other vehicles/cyclists/foot traffic moving around.

I think the argument they make is quite interesting, with vision (our eyes) we do anything and everything in the car. Therefore, camera's are like eyes so they should give comparable performance. The fact is that the dynamic range of the eye is insane and no commercial camera can currently even come close to it. Once that technology is there, (which is physically impossible with the current sensor tech) I'd agree with them.

Well, the app was originally called Vigilante with the goal of enabling... mob justice. So, this really isn't surprising.

Applying contemporary growth hacking and engagement techniques to making people feel afraid and seek private security is just abominable. LA county is 10 million people - there are going to be all kinds of criminal activities on any given day, but rarely anywhere close to you. The app though will make sure even a minor thing a few miles from you gets you revved up. Just a recipe for more social disfunction.

The worst part is that LA county and city decided to use Citizen for contract tracing during the pandemic, which drove up downloads in the LA: https://covid19.lacounty.gov/covid19-news/la-county-city-lea... - they really need to push back on this vigilante stuff now.
Presumably because high-SES folks can do even better if they remove standardized testing. I.e., it can be true that "high-SES correlates with high-SAT" but it does not follow that removing SAT requirements will result in more equal outcomes. It's very likely that SAT requirements level the playing field considerably if not completely. It's probably quite a lot of work (and cost of education) for those high-SES folks to get such high SAT scores, so by removing those SAT requirements they can be admitted more easily/cheaply.
I don’t think your response is relevant, but ignoring that, I also don’t think my government is going to spend the tax money it squeezes out of me in a socially beneficial way. If I thought they would spend the money productively I would be less driven to avoid unreasonable tax burdens.
Have they delivered ANY of the features of FSD? Is even Summon out of Beta? I have a Model 3 but I refused to pay for basically a Kickstarter version of FSD. For the purposes of revenue recognition, they can't claim any of the revenues until the features they promised are delivered. But the fact that it has been years is still shocking to me. How have they avoided getting a class action lawsuit? And the fact that they admitted that their "FSD" is only Level 2 is mind blowing. Some of the statements by Elon are borderline fraudulent, if not fraudulent, like how he expects the price of FSD to be worth more than $100k.

And this seems to be par for the course for Tesla. If you look at what they've done with Solar Roof, they have increased prices by 50% for people who already have signed contracts. It's blatantly illegal and yet they are fearless in trying to trick people into cancelling their contracts. Hopefully the current class action lawsuit for Solar Roof gets traction because it's incredible to me that Tesla behaves like this and doesn't get their ass handed to them in court.
Yep. Formally in CS, there's no difference between a "compiler" and a "transpiler". They're both names for the process of program translation. All compilation is "transpilation", even when you're compiling things like C++.
> It's crazy watching the world turn into a dystopia and being powerless to stop it.

We feel powerless - I feel it too at times - but we're not. Who would have thought the world could change this much? We can change it also for the better. The social world we envision is very deeply ingrained in humans, probably through evolution. We are social creatures, not sociopathic.

I think a start is standing up for our human values (honesty, respect, fairness, justice, compassion, humanitarianism, reason, knowledge, etc. etc.- doing the right thing). The Internet has been seen as a different place, an experimental place, where those values don't matter or don't apply - we could try something different; it has been like a virutal game world where we can act out being someone different. The experiment is over. It turns out the values do matter (of course, there's reasons they survive human history) - and they matter more than in the physical world, due to the power of communication on the Internet.

It's time to stop accepting what we wouldn't accept at a dinner table or in a professional social situation (or choose your analogy). The Internet is part of IRL, no different than a restaurant. HN, for example, has much improved; I hope it will go further and adopt that concept.
Ok, I take your point, but let's say we need to share these credential objects between different systems that do not have prior knowledge of how to evaluate the credential data. Also, let's say we constrain the logic to only allow for evaluation of any given part of the credential data against a binary "pass | fail" matrix.

What is a better way to share this important part of the schema (the matrix) without resorting to letting the "business logic" perform the evaluation? Optimally, any matrix should be able to run against the same business logic for evaluation.

Also, though I understand why you say that, we won't have "100 other yahoos doing this nonsense," and each schema would go through a pretty thorough review process.
