One big limitation is the Carnot efficiency - for any heat engine (which internal combustion engines are) there's a maximum upper bound on the efficiency, which for gasoline and diesel is around 37%. Beyond that point you can't extract any more energy out of the waste heat without removing energy from somewhere else in the system.

You can control the side effects you may get from a medication you take? If you get an infection you are taking meds. If you get kidney stones, you are very likely getting meds, if you injure yourself and need surgery you are getting meds. These carry risks, therefore, every time your chances of "perfect health" are decreasing.

I get that most people on HN, can control the air they breath as they have the means to decide where they want to live, this isn't the case for most of the people.

Cancer is literally just a numbers game, people in perfect health at their PEAK get diagnosed with cancer. A top club soccer player is now going through testicular cancer treatment.

I am not sure how general person can control any of this.

It's not that clear. Russia had huge stockpiles of stuff. But it's old, and much of it is in poor quality. The tech being deployed in Ukraine is very poor. We've seen WWI era rifles, almost WW2 era tanks, tanks that don't work or don't have gunners, planes without navigation. A gun is still a gun, but they also don't have as many people. The Russian army was a peacetime army. It wasn't ready for war and they've had a tough time recruiting people in the past several months. They've also drawn a hard line against recruiting from ethnic Russians in places like Moscow. The biggest conflict though is in getting the stuff to the frontlines. Their comms, intel, and logistics are pretty poor.

But they do have a lot of people, and if they're willing to let them die, it'll take a long time to get rid of them.
That's a specific type of expectation confounding that comes from a dangling modifier. English is particularly good at creating these types of sentences and it leads to some of my very favourite jokes.

If the lady had said "Can you spare a few minutes to discuss supporting cancer research" there isn't any ambiguity in the sentence and then no joke.

Community used these to great effect. For example:

Britta: Yep, I’m getting serious. I got a backpack, got a new notebook. Oh, I got one of those see-through yellow pens so I can do that thing where you colour in the words.

Shirley: Highlight?

Britta: Probably the backpack.

It's wild to me how much of right wing rhetoric on Hacker News is portrayed as "simply how it is" and "activist logic" is portrayed as always wrong, a failure, and counter-productive.

None of the situations described in the parent has ever happened. Nor do any of the scientific studies agree with the positions above that are implied to be facts. However, because it is written dispassionately (even condescendingly) the flaws will be ignored and the sentiment applauded.
I've been barking about this for years, and is the reason I'm forced to pay for YouTube Premium as well. The amount of time alone ads cost me insane, and the bandwidth (at home or especially on mobile) usage involved means almost any form of video advertising is incredibly costly to me, and any free service costing one hour of minimum wage work per month saves me many, many hours (in literal cost hours and pure time) in the long run.

Petrol engines can physically only achieve around 55-60 % efficiency, so getting up to ~35-40 % vehicle efficiency is actually really good. Large scale Diesel engines get really, really close (within a few points) of the hypothetical frictionless-no-heat-radiation-no-flow-losses efficiency possible with their parameters.
Can't say I agree. When I go to my local mom & pop grocery store, there are 3 employees and only one of them works, the other two seem to just be on their phones. We should either find a way to cut that business down to size also, or abandon the entire idea.
You have to go a great length to convince children it’s important. My feeling is that most don’t care about natural sciences.

Also, boiling things down to ELI5 means you have to trust the scientists. It’s not like Newtonian physics where you throw a ball and a feather and they fall at the same time in vacuum.
Thank you, netizen. Your wumao is on its way.
I always have the same response to discussion of low/no-code and graphical programming environments:

If you think it will make things easier you have confused typing to be "the hard part"

There is a lesson here for ambitious system architects: the most dangerous enemy of a better solution is an existing codebase that is just good enough.

For the units they deliver to those markets. You haven't demonstrated that the US models are being adapted to European requirements, rather than companies selling European adapted models. My understanding as a lay-person is that the latter is much more common, since the European market requires adaptation anyways (more diesel engines, more manual transmissions, different driver side, &c.)
As an aside, it's a wonder to read casual accounts of office work where teams will play with toys rather than be allowed to go home to their families or other interests
Unfortunately, HN users tend not to care about the quality of news sources when it comes to "culture war" issues. This'll just turn into a platform for people to air grievances and repeat their ideological stance. If it makes you feel better, most people won't actually read the article.
I'm fascinated by stand-up comedy. I took a course a couple of years ago (online thanks to the pandemic) and it was so, so much harder than I expected it to be! By the end of the course I was nowhere near having a "tight five" that I was ready to perform in public.

I've continued to pay attention to it since, and it really is amazing how much skill and preparation it takes to put together anything that even comes close to being a decent performance.

Great stand-up comedians have inevitably spent hours of time refining every sentence that comes out of their mouths, despite their delivery sounding entirely natural and unrehearsed.

I've done some hobby projects in Rust. One was a SIMD abstraction library, where you could write code that looks more or less like SIMD intrinsics, but it would either at compile time or runtime select the SIMD instruction set for the target cpu.

The traits/generics/macro system made that feasible, though messy. You can do similar things with templates in C++

I used a Z Fold 3 as my primary phone for a few months.

It dramatically changed my phone usage habits. The super slim front display is just slim enough to be annoying to use, so I'd find myself checking/acknowledging notifications without finding myself engaging and becoming distracted as frequently as I used to. I also found that when I was sitting around somewhere bored, I was much more likely to start reading an ebook than before, as the form factor is really fantastic for that. My reading habits have dropped back off now that I've returned to using an iPhone.

and a handful of posts by dang, sama, pg, etc. over the course of the years. most of the rest is what long-time users have just figured out through observation. There's a Git repo[1] out there that aggregates a lot of that stuff, but keep in mind that it's technically unofficial. That said, I think most of what's there is widely considered to be correct.

I haven't double checked this, but I strongly suspect they're bandwidth limited by the total amount of uplink/downlink they have, not the inter-satellite bandwidth.

Inter satellite links are basically fiber, just without the fiber (instead they just point the laser in the right direction and rely on the fact that space is empty). Up and down has to use valuable radio spectrum, handle interference and atmospheric effects, etc.

Almost everything in Rust 1.63.0 appears to be an improvement in the standard library. Scoped threads no longer require a third-party library, some types support "const" better, and a bunch of existing types got some useful new methods. The only real language change here is the "impl / turbofish" one, which allows something that should work, but which wasn't allowed before.

I'm not sure it would be realistic to totally stop adding features to the standard library, or to stop making existing syntax work the way a Rust user would expect. I would hope that any actively maintained language does things like these.

No, it really isn't. "Control your medication" might leave you dead if you are diabetic or leave you hearing voices if your meds control a psychiatric condition.

In the same vein, you don't really get a choice in most cancers. Sure, you can do things like never smoke tobacco, but you might just be an 8-year-old with bone cancer. And lots of other afflictions and diseases are similar in this manner, much like you probably won't be able to avoid whatever cold is circulating in your workplace.

And I've not seen any proof otherwise.
I'm more worried about how easily media spins stories that have a smidge of sense into a scandal by cutting out details and making the headline sensational. While the police overstepped in this case, the article clearly wanted this specific take to be posted to spur discussion and clicks. And we all keep falling for it.
I just want to be able to sign up for a do-not-message SMS list and a do-not-spam email list, specifically for political candidates.

The past year in particular I've been getting as much as daily political fundraising SMS's but every time it's from somebody new. Random representatives from across the country. I reply "STOP" each time and that same one never messages me again, but there are literally thousands and thousands and thousands of people running for state legislatures out there...

I'm fine with Google exempting political e-mails from other commercial spam, AS LONG AS there's a setting to send them straight into the trash.

And I say this as someone who's very politically active -- but there's nothing democratically enabling about getting messages from random reps in Wyoming, Hawaii, Idaho, Virginia, none of which are places I live or can vote in.
Ah the tolerant, progressive socialist left Europeans.
I disagree. I’m calling the police.
So they wanted him for an interview (which would end up being NFA'd).

They went over by arrangement with him for a voluntary interview, the guy decided to be an arse about it, which created the conditions under PACE (Policing and Crime Act) that necessitate arrest.

Arrest occurs, mans fucking shocked.

Play stupid games...

Now I will say, the Mal Comms laws are a disaster. But Jesus Christ the Mirror misrepresents this by a mile.
I don't agree that that's what's happening.

A law exists in the UK about using public communications networks to send grossly offensive or indecent communications.

Somebody complained to the police that this chap had maybe broken that law, and from the embedded video, it sounds like he wasn't willing to come voluntarily to the interview room.

So what do the police do? Tell the complainant, sorry, you feel like you're a victim of crime but the alleged offender wasn't willing to be arrested?

Nobody is picking ideologies to enforce. I don't see how the content of the supposed offensive tweet, is relevant to the decision to interview this chap under caution.
I'm hesitant to reply further in this thread because I get the feeling I've made some people feel attacked and criticized which is not my intent, but I really don't think the issue here is the neurotypical manager's inability to admit they are wrong. Everyone in this conversation is wrong. Everyone believes that both sides of this conversation are having the same conversation, when instead each side is having a different conversation.

To the engineer, they've been asked a specific question "should we rewrite in React?". They assume the manager's has a specific motivation for asking, because the engineer would have a specific motivation for asking, and are asking questions to try to get at that motivation and determine if React will fill the manager's needs. The engineer is having a reasonable conversation.

To the manager, they've asked an open ended question "should we rewrite int React? What are the reasons why and why not? What issues could it address? What are the drawbacks? Any guess on time-frame? Cost?". The question "what issues is the site having that React could address?" is contained in the manager's question. The manager is also having a reasonable conversation.

The breakdown happened when both sides fail to realize that the other person is having a completely different conversation than they are. To the manager turning around and asking them "what issues are you hoping to address with React?" is the same as if someone asked "does this truck have a lot of horsepower?" and I replied "I don't know, how much horsepower does this truck have?" I'm echoing the question back at them. It's confusing and they don't understand why I'm doing it, and it's naturally going to make them feel uncomfortable and agitated. Meanwhile the engineer doesn't understand why they someone is getting agitated over their reasonable fact-finding questions and start getting... well confused and agitated.

In general, I actually blame the manager more for this breakdown in communication, and that's where I'd put the majority of my coaching efforts. After all, probably 95% of a manager's job is communication, and I view understanding how to change your communication to establish a rapport with other people working outside your framework to be part of the job (this kind of breakdown can happen a hundred different ways, it's not just neurotypical vs non). Sadly, most managers never getting any kind of training on this, and many (most?) are abysmal at it.

But the fact is both sides of this conversation failed to understand the conversation the other person was having. No one is "wrong" or everyone is.

Since we're talking about freeciv, civ2 on deity is pretty easy if you know what you're doing. It's not even a forced way of playing, you can decide to win with just one city, or you can decide to spam cities with less than 3 population to avoid population penalties, and there's many other strategies.

If you don't know the game well enough to win at the highest difficulty, it is not degrading to play at lower difficulties to learn the ropes while still enjoying the game.
My own conspiracy theory is that the only reason this story got traction is because it carefully sends the message "EVs are not sustainable, and might never be".

There's enough people being paid to tell clear lies that I don't feel I'm paranoid to suggest that writing such an article (which seems very careful to not be particularly positive about current EVs) might get you money from fossil fuel interests and/or they'd hype it for visibility.
> I don't think you would generally expect people to say "tax euros" or "tax pounds" or "tax yen"

Isn't the idea that all suffering is a challenge of god key to Abrahamic religions. I always hear it from anyone religious when discussing that rational of why there is suffering the world when God can end it. And from my quick read of Job's story, it seems that it does exemplify that.

> Companies already have huge volumes of data on consumers even if gathering was to be shut down now.

This is a thing that I keep telling people that no one seems to realize. If by some miracle all of the surveillance stopped now, the data already collected would still be effective for some future bad actor to use 10-20 years from now. I don't think that most companies would keep the data for that long, or many for even very long after some theoretical regulation, but they would certainly sell it to someone who would, and the NSA will be interested in copies of what it doesn't have.

If, 20 years from now, in a new town with new friends and a new job, living under a new government, it becomes important that people don't know you are gay, you're out of luck.
> No one knows where to put the trash. That was the major reason for the phase-out, that no one knew how to handle that.

We know so well how to handle it that we are wondering how to keep people out of the storage places in the event of a civilization collapse. That is, where current languages are forgotten and we forget what nuclear is. That's how advanced in storage we are.

Rust has replaced Python for me in my personal CLI tools where I expect to use them as an ongoing basis. At this stage I am almost as fast writing Rust as Python, find the Rust projects much easier in terms of environment setup than the whole pipenv/poetry/pyenv world, and enjoy the instant response of not having to wait for a python interpreter startup.

I also have some side projects like a gameboy emulator, where it's nice to have what is effectively a lower level language with the safety and features of higher level language.

My day job is mostly Java/Javascript though, rewriting the world isn't yet worth it, but there's certainly one or two of our systems where if a rewrite in another language was on the table I'd make the case for Rust
I'm a huge *BSD fan, and I know one of the amazing things about NetBSD is that it's been ported to everything.. but an OS which is ported everywhere but runs no where in production feels like a really quirky project to me.

Likewise, OpenBSD, FreeBSD will have some adoption (vs Linux, Windows) on the server front, but I worry they won't win the hearts and minds of developers unless there is a solid and modern laptop solution -- this obviously requires developers who are able to get things working.

Before everyone jumps in and says they're running *BSD on their laptop, I'm talking about a modern laptop, and being able to develop on it. I recently tried to install FreeBSD onto a modern laptop (Dell XPS) and it totally failed in every way possible. No power/sleep control, fans blasting, CPU burning through my desktop, and I hadn't even gotten to the wifi and video support to get X working. On Reddit I was essentially told it wasn't worth the pain.
Is there anything factually incorrect about the article though?
Your honesty was refreshing compared to others who jumped straight to hate, because there was no story about them as 17 year old inventors (so clearly he does not deserve it either).
