It is crazy to me that these cars are always recording and streaming the result to Tesla. Sure, that data might be good for training self-driving cars, but also a lotttt of other things.

But, it is the truth. Except, such can go both ways. There can be better or worse options that present themselves (to include beyond looks).
It you mean is that he will destroy Twitter, then I probably agree. Otherwise, the way he fools around social networks will not do anything good for humanity.
> because the gap is so large

I drive with a six car gap and even that was a close-call when someone had a contact about 3 cars ahead.

The good part is that if the car in front of you flashes the brake lights, that seems to trigger the braking. And some of the newer cars blink hazards automatically when braking hard.

My Subaru is also vision only (Eyesight), which also has the cameras too close together (in my opinion) to detect a car ahead braking, but it did not slow down quickly when facing a stationary car facing the wrong way around (my feet went down before the car did anything).

All of these need more parallax, at least better than a human to do this well. But they do react to visual cues like brake lights and hazards. Though sometimes, it sees a motorcycle nearby as a car in the distance simply due to the lack of parallax.

"more sensors good" is not always a good thing, when the sensors disagree with each other. Sometimes more sensors just mean more corner cases and braking at bridges throwing shadows on the road.

So just removing something feels wrong, when I don't see them improving the thing they're putting more eggs into.

I think this is where Tesla is not credible right now, when they say they're improving something in the car, but it is a thing I cannot see, check, confirm or test.
Case insensitive functions are common. Filesystems are just one of many places where this kind of function is expected.

It's just a particularly common canonicalization function. Canonicalization is a common need across all languages as we've already clearly established.
> What happens when it’s a strong chess player

A strong chess player would have to weigh the risk of losing all their progress and reputation if caught cheating.

After this current situation, I expect the penalties for being caught cheating will be severe. Whether the cheater is banned from all future events or not, nobody will want to support them, nobody will want to associate with them, and they will essentially be cast out of the entire chess world.
I "solve for x" all the time, though, admittedly, outside of work, it rarely gets more complicated than a simple expression with a fraction or two.

However, what is aggressively useful is dimensional analysis. When I'm doing a calculation and need to quickly check that the formulation is right, checking the units works every time.
Why do electric planes like this one have many smaller motor, as opposed to 1-4 engines like typical planes do?
I suspect this exchange never happened, but at any rate:

When the teacher justifies the subject not on its own merits, but for its alleged nootropic effects, that's how you know it's either a waste of time or the teacher himself doesn't know what it's for. Same for "it builds critical thinking" -- another 100% reliable hallmark for a bunch of BS meant to waste young people's lives on classroom exercises and homework. 21st century version of digging holes in the desert to build character.

Calculus is useful for hundreds of things; if the teacher has to resort to this dodge he ought to be ashamed of himself. What a waste of an opportunity to tell them about its applications in civil engineering, in control theory, in statistics, in orbital mechanics, in 3D graphics, etc etc. If I had heard what that teacher said it would have killed my interest stone dead. Just another hoop I have to jump through, for my own good.

And this isn't to say that everything must be justified on utilitarian grounds -- Shakespeare is not "useful" for anything but we have it in schools because it's inherently worthwhile, it's part of what makes life worth living.

Not equity. And probably at worse rates than could have been obtained in April.

Hydrogen is light but tanks capable of 10,000psi don't tend to be. Nor particularly are cryogenic tanks but at least that improves the situation volume problem by an order of magnitude.
Yes, I think it is a categorical truth.

Yes, I chose an extreme and absurd example to illustrate the point. I said as much in the post.

I agree that there are many realistic examples of compelling action. If you provide some I would probably disagree that the government should be doing them.
Apparently the Twitter board has something to say as well; the news is they're withholding any statement until they determine whether this latest move by Musk is a "legal ploy." Prudent, I suppose.

Also, you wonder if all of Musk's backers, debt holders, whatever are really still 100% on board. It's been months and people lose patience when so much money is in limbo.

Back in April the NYT wrote that regulators were unlikely to hold it up. That opinion seems naïve to me given the politics.
Well I did minimally adjust my priors based on that evidence actually. The fact that a lot of people are making claims here also adjusts them very slightly (I already knew many people felt this way). But I've got heavy weighting on policy matters needing non-anecdotal data, so not much of a change really.
Unicode absolutely does not fix the issue of not knowing the encoding of a legacy byte buffer with text in it.
The article mentions airplanes waiting on the ground, but I do wonder what happens during flight. I suppose the engines create plenty of heat after all.
I don't find that too odd, because I believe the plaintiff, Twitter Inc, can more-or-less get a stay on request, especially if it's likely to make any further burdens on the court become moot. So wording it this way is just being clear about what Musk wants Twitter to cause to happen.

Further, Twitter's complaint only asks the court to compel performance under the original agreement - it doesn't ask for extra damages from Musk's flip-flops. If Musk is offering exactly that performance, there's nothing for the court the compel, unless & until things change again. (If that happens, the stayed action can resume – and the judge would be even more disposed against Musk et al.)
I am not a Musk fan and I really don't want him to buy Twitter. However, neither do I want him to get away with his shenanigans. I want to see, for a change, a billionaire held accountable.
Yeah agreed. When I see these problem statements, I see us addressing problems that are by-products of vulnerability fatigue.

I.e “be lazy and ignore those vulnerabilities by using our tools!”

It hardly solves the true issue of an industry wide challenge of lack of useful information or even transparency of said information from responsible parties. I believe this laziness is what got us here in the first place.
This is the most interesting part for me:

Computers have “nearly infallible tactical calculation,” the report says, and are capable of beating even the best human every single time. The report says dozens of grandmasters have been caught cheating on the website, including four of the top-100 players in the world who confessed.

I can't really comment it, but I leave it here if you haven't read the article.
There are multiple tells that this move, just like the removal of radar, is supply-chain and cost-driven and not actually driven by engineering.

If this were a planned move, the software would already be ready to replace it. It is not. Cars without radar still aren't at parity with the car that have it, although they "fixed" this a few weeks back by simply turning off the radar on the older cars.

The parking sensors on the Tesla are really good and very useful. They show a rough outline of what is around you and are displayed very nicely compared to some other cars. It is a real shame to remove this, and downright dishonest to characterize it as some kind of leap forward.

The cheapest bargain-bin cars have this feature. Your $100k+ Model S or X will not.

Even more concerning: some features simply cannot be replaced by camera. Tesla infamously does not have a front bumper camera, making it impossible to detect obstructions occluded from view by the hood. For 3/S, which are low, this means it will be impossible to detect low obstructions like too-high concrete wheel stops and similar obstructions. Once the hood has occluded the view from the windshield cameras, these obstructions will cease to exist.

Laughable that this is being done on cars from a high-end brand, and that the remedy for customers who are getting worse cars today than you would get yesterday is to wait for these features to "be restored" at some indeterminate time in the future.
Well, he's overpaying for Twitter by $20b compared to when he originally made the offer.

On top of that, he's partially funding it by selling Tesla stock that is also worth less than it was when he originally made the offer.

This is an incredibly expensive game of 4D checkers.
Hire vs. Do Yourself for Indies
Had a conversation about this (podcast) and was looking to get some perspective from other indie creators / founders. The article I linked is just a boiled down TLDR from a 1 hour conversation.

What do HNers think ?
I've always thought of C++ as the most complex programming language I know. With each revision it becomes more complex. I gave up and just moved on to Rust a year and a half ago. I have no regrets.

C++ has not quite joined Perl, PHP, and Java as languages I will not work with anymore, but it's the next logical candidate.
Perhaps we as a society will learn that Twitter is not, and should not be, how we measure how society feels. Twitter is without doubt a net-negative on society and I'd be glad to see Musk drive it to the ground.

The amount of "journalism" from previously well-respected institutions that can be summed up as "some people on Twitter didn't like thing, here are there tweets" is shocking.
It's a little short of full-on financialization of a cattle. So, perhaps closer to beef/dairy futures? What's missing is a bank classifying the cattle, selling them fractionally, and creating a hedging instrument.

If you own oil or soy futures, you can go get the product if you like (to everyone's inconvenience). This is not far off.
This is exactly how I get clued in on how someone is cheating in a shooting game I play.

You can tell how experienced someone is based off the gun they use (some are stronger than others), whether they use cover or just run out into open spaces and shoot, how they move, whether they use 'gadgets' like grenades, and so on. A lot of novice players don't even use the sprint function to run.

When someone who literally just walks around the map but can laser everyone with headshots (which have a significant damage multiplier)? They're cheating.
I'm a software developer, but I did these kind of jobs when I moved to New Zealand under the Working Holiday Scheme. The minimum wage what I got for these jobs was more than what I earned as a software developer back in Hungary. It wasn't just free gym as we needed the money to support ourself, but it was still relaxing to not care about the big picture and only do what I was told to do without any responsibility.
The alternative - an environment where innocent people were sometimes getting expelled - would be worse when it's just a game.
Apple should be coerced into adopting USB-C on iPhone. Their refusal to do so has been an explicit, repeated failure on Apple's behalf. The iPhone is one of the only remaining Apple products that does not use USB-C, and it's exclusion is entirely unnecessary since USB-C's base-spec was designed by Apple and well-exceeds the capabilities of Lightning.

At the end of the day, it's a serial port. People should stop acting like Apple is being asked to re-engineer the Death Star, and recognize that this is a change so rudimentary that people on YouTube do it for a fun weekend project. It's the textbook definition of a failure, and the EU has every right to hold Apple accountable for the insane things they call 'innovation' in the US.
I did not make any comment about the GP’s post in particular. I made a comment about a funny phenomenon of posting on HN in general. I specifically brought up posters using highfalutin’ fancy speech to cover an ardent pro-cop bias.

There are some posters that will use their perceived skill at language to do somersaults of logic in order to eventually land at “the police are the arbiters of truth” or something similar. The primary tactic is to use high school debate club language to put words in other people’s mouths in an attempt to discredit any view that doesn’t align with their premise of “the police are arbiters of truth.”

Do you think that that phenomenon does not exist?
> Of course, that is almost a tautology

Inflation lags the money printing, so it isn't a tautology.

> So what do you do to get that sweet spot of about 1-2% inflation?

I'm amazed that propaganda of a sweet spot gets so heavily embedded into the popular wisdom.

If there is a sweet spot for inflation, it's 0%.

Note that the US had net 0% inflation from 1800-1914, while growing from subsistence farming to superpower.

The financial industry doesn't make money out of bits and bytes. They make money out of other money and lose all of it every 10 years or so. We're seeing it real time today hilariously enough.
I'd say he could not come to a conclusion that there were cheating.
An autonomous vehicle is operating on a road network designed for humans with eyes. If we are aiming for the kind of “common sense” required for parity with a human driver it seems intuitive that the vehicle would have sensory inputs in common.
Well he clearly didn’t think it was worth it, given the attempts to backtrack out of the deal.
It is a bit of a semantic dispute, but not an unimportant one.

We are causing a major extinction event that is up there with the worst ones the Earth has experienced. That said, the end result is likely to be that we either go extinct or come very close and the remaining life on Earth picks up the pieces and starts re-evolving new biodiversity from the diversity bottleneck.

It's happened before and life on Earth, as whole, will come out the other side of this bottleneck and move on (unless we've tripped some unimaginable feedback loop).

...it's just likely we won't be included in that life.

...and a major extinction event on this scale is nothing to sneeze at either. Really it's chilling enough that we, as a species, are potentially having a similar impact on Earth's biodiversity as the asteroid that killed the dinosaurs. There's really no need to exaggerate that.
Personally fast charging changed everything. Plug phone at random occasion (few minutes before leaving home or during short ride) and never have to think of overnight charging. I've mounted magsafe thing on my car dashboard and it was somewhat of disappointment. Sure it's convenient but slower charge was def noticeable.

But the whole point is being able to depend on a cable that just about everyone has. All of your gear has USB-C. Apple just being cocky.

Is that common knowledge, what's the source of that I'm curious.
Afaik inflation devaluates stock relative to bonds and its small 101 of economics but Im no expert
I think the phrasing of "explicitly memory-unsafe" is wrong[1] in letter, but true in spirit. At the end of the day `std::optional<T>` is only marginally better than `T*`. And I'm sometimes not even sure if it's better or worse; the extra API surface you describe is nice, but in practice it's just a mirage of safety, since its API subset includes that of a common pointer. And I've seen ample code use the unsafe API because (convenience/performance/inexperience).

But at the end of the day, I guess my comment is also irrelevant, because we as developers should strive for correctness, not brevity, in code. If we can achieve both, the better. But alas, brevity and correctness are in an antagonistic tension in C++. So when we want correctness in C++, we should also be prepared to swallow a large portion of spaghetti Bolognese.

[1]: Or at least no more melodramatic than the phrase "aggressively wrong" lol
I haven't kept tabs on modern PCIe / NVMe, but I was figuring transfer would be DMA blasted w/o CPU interaction.

Any idea why the Celerons gunked up so badly? Maybe single core blocking?
Most people don't realize that the online chat functions for a lot of customer service sites show every character you type, not when you hit 'enter' or 'send'.
He's basically the Joker at this point. No apparent rhyme or reason to his actions, and no overarching goal. Just chaos.

You hate to see it. Or at least, I do. I had an immense amount of respect for Musk based on his work at Tesla and SpaceX, and that respect has basically evaporated now. It's as if he's no longer the same guy at all.
A lot of people think that Elon Musk was the modern Nikola Tesla or (yes) Albert Einstein. These texts let them know that he is actually the modern PT Barnum.
Always happy to talk, but I’m not sure how helpful I can be.

I was diagnosed ADD as a child (~6 years old) but I wasn’t correctly diagnosed with bipolar until I was 33 after voluntarily seeking treatment on the recommendation of my primary care doctor.

As far as treating the ADHD, my psychiatrist didn’t bother with a formal diagnosis. She just decided to treat the executive function issues I reported.

Medication is trickier. I can’t use the traditional stimulants (or caffeine) without risking mania and panic attacks.

So I’m taking Wellbrutin (an NDRI) which is both an antidepressant and a stimulant. It helps with ADHD, Anxiety, Depression, and sexual side effects from antipsychotics.

I don’t have any major side effects to report than increase in sexual function and keeping me awake for the next 10~12 hours. (So no afternoon naps to recharge.)
In ultima online players were split into 3 categories:

Blue
Gray
Red

and later Orange

Blue = "good". If you are in a "guard protected zone" and you attack someone "blue" guards will come and murder you instantly. As long as someone says "guards"

Gray = "criminal". You commit a criminal action, you are gray. If you attack someone gray, no consequences will be made against you. Only thing is if I am gray, and you are blue, and you attack me, you turn gray _only to me_. Gray expires in 5 minutes.

Actions that cause this: stealing, healing someone gray / red, attacking someone blue but not yet killing them.

Red = "permanent criminal". You are red as long as you have any player kills registered to you (they decay 1 kill per 8 hours I believe. A PK is only counted if you kill a blue player or participated in killing a blue player.

There were a few fun exploits:

You can transform into a creature. This meant you turned gray without any crime. Well if someone attacks you, you can attack back. So it was a scam we used to pull where there would be occasional attacks against the town, I'd run around screaming that I'm a noob and need someone to get a monster off me, and the monster would be a friend.

Well the friend had a nearby tamed dragon that can now freely attack the guy who flagged himself against my friend without consequences. And anyone who assists now has a dragon to fight (killable, but lots of resources spent, and usually would take a few people to do, AND my friend was a competent mage, so now you also have a mage gunning for you). We didn't always succeed but it was fun. I think we got suspended a few times for it. lol.

There were some tricks to getting people to attack the wrong target and thus flag themselves in town and get the guards to kill them. But it wasn't commonplace. Maybe during beta there were problems.

Oh yeah, orange. Orange were players participating in guild wars. Orange players can attack other orange players. It is basically permitted criminal activity among those participating in a guild war. And in Order vs Chaos you also got the best shield in the game for free for being on either side.

I think the easiest answer to this is "does it hurt to learn it, though?"

Many things you learn aren't directly applicable to everyday life... but learning how to think and _learn_ is priceless.

I also assume there's more objective reasons... like teaching 100 things, knowing full well most people will only remember 10... but that's still better than 0.

Yea, there's a time cost associated with learning but its certainly not the worst price to pay.
Good point.

I wonder if pg_squeeze would work well in a large-scale heavy-writes case. There is a very sad and hard limit of single-threaded walsender that can saturate a single core (depends on CPU and schema / writes complexity; for example, I saw systems where it happened at ~2 WAL/s, or roughly 1-2 TiB of WAL data generated per day). So at some scale, the process might not converge.

Also, we apply changes in the same system, there are 2x writes anyway – though, it happens asynchronously with pg_squeeze, unlike with triggers (though, that "delta" table pg_repack temporarily writes to, it's very light in terms of indexes, and we do only INSERTs, so this amplification is not 2x in terms of IO and timing overhead, right?)
I would say that these subjects are more likely to turn into vocations than the teaching of how law and economy works.

I see it like when I learned about programming, I was frustrated to learn about language theory, complexity, graphs, etc. I wanted to learn langages, frameworks, specifics for being ready to work right at the end of my degree but it would have made me more fragile and less versatile to future changes. Although law and economy are less likely to change as fast as the latest cool tech stack so this example is not the best.
Right, the thing the Fed is doing by raising rates is increasing unemployment but trying to not come right out and say it. Increasing unemployment decreases demand and therefore prices. A hard recession is how this is going to end IMO.
You could train a neural network to filter through likely human moves from the engine's top recommendations and never get caught.
