More importantly, the HQ is built in California, which despite appearances isn't a capitalist dystopia but a local government dystopia.

Any random local government staffer is the most powerful person in the universe and obeying them is a religious edict. Apple has zero power to disobey anything in the fire code and they're probably not even capable of imagining doing so. That's why the random suburb they're in has the best public schools in the country and all the houses are like $5 million.

As an example there's currently a big empty lot next to said HQ where the mall used to be, because a random woman on the city council has blocked apartment construction for the last decade, because she thinks Apple employees will move in and molest local high school students.

I think that a wire protocol could support that with a query response for supported versions and functions. The decision of dynamic linking removes the overhead of serialization, but removes the option of static linking.

How this "impugns" apple at all?
The pilot in command can refuse an aircraft because of unresolved mechanical or technical issues, and sometimes issues that for example are fine on a clear calm day can just not be in weather. Remember that the pilots themselves are responsible for the safety of the aircraft and all passengers for the duration of the flight, so it's up to their judgement to make sure that a flight is safe.

But a fire on a plane is pretty much the most dangerous event you can have on a flight. Especially lithium battery fires since aircraft don't have the right extinguisher for them, and staff are generally trained to quarantine the fire just long enough so it can be taken care of on the ground.

It's probably just a notation/definition issue. I'm not sure if "grad f" is 100% consistently defined

I'm a simple-minded physicist. I just know if you apply the same coordinate transformation to the gradient and to the displacement vector, you get the wrong answer.

My usual reference is Schutz's Geometrical Methods of Mathematical Physics, and he defines the gradient as df, but other sources call that the "differential" and say the gradient is what you get if you use the metric to raise the indices of df.

But that raised-index gradient (i.e. g(df)), is weird and non-physical. It doesn't behave properly under coordinate transformations. So I'm not sure why folks use that definition.

You can see difference by looking at the differential in polar coordinates. If you have f=x+y, then df=dx+dy=(cos th + sin th)dr + r(cos th - sin th)d th. If you pretend this is instead a vector and transform it, you'd get "df"=(cos th + sin th)dr + (1/r)(cos th - sin th)d th, which just gives the wrong answer.

To be specific, if v=(1,1) in cartesian (ex,ey), then df(v)=2. But (1,1) in cartesian is (1,1/r) in polar (er, etheta). The "proper" df still gives 2, but the "weird metric one" gives 1+1/r^2, since you get the 1/r factor twice, instead of a 1/r and a balancing r.
is there any reasoning that for besides highly reductionistic and repetitive systems like crystals, quantum computing can compute quantum properties of molecules?

That difference in Asian societies as against Western ones doesn't come from "higher standards" or whatever; it comes from a much more mundane reason: not doing good in school here literally has immediate far-reaching consequences because everything is scarce and up for brutal competition.

In the West kids can randomly decide to drop entire years after high school, or even skip college altogether - because it's (apparently) easy to not be immediately destitute without a good job. In India and China children grow up witnessing how much of a divide that makes, and how thin the line seperating their fates from "respectable" to brutal poverty is. No kid growing in such an environment will take school lightly.

> never having heard not to put a battery in checked luggage

Maybe not conventional batteries, but you've been disallowed from putting lithium batteries in checked luggage for at least 16 years. I remember being dragged into the bowels of an airport by security to open my checked bag because I'd forgotten a device in it. That was in 2009.

When you check in bags they ask you to make sure there aren't any rechargeable devices or battery packs in them and this has also been going on for a long time.
Forgive me, but I feel like these guidelines are enforced very selectively. Paul Graham's last post against "wokeness" staying on the front page for two days left me with a very bad taste in my mouth. Why should his political crusades not only be allowed on here but also promoted?

Similarly, why are some DOGE posts allowed to pass through the flag-filter but not others?

I'll take your comment as a hint to take a break from HN. But please, do consider further detailing what kind of political content is acceptable or not.

> healthy and nutritious food isn't even available in poor neighborhoods, only fast food and convenience stores.

Don't you think you might be getting things backwards? The offer in poor neighborhoods is determined by the demand in those neighborhoods, not the other way around. The shops are selling what the people want to buy.

I've lived in mixed neighborhoods in Europe, where everything is available within walking distance. The poorer people still buy junk food while more wealthy or educated people buy healthier food.

Many countries would have to buy nuclear fuel from other countries much like they do for gas and oil. On the other side very few countries can build their own solar panels so it seems the same sort of problem. However if you accept to depend from potential hostile countries at least solar panels don't do much harm when they fail and it takes very little effort to install the equivalent amount of power of a nuclear power plant. If we only could all get along and have a global power grid with always 12 hours of sunshine on it.

The "DeepRecursiveFunction<T,R>" could be implemented in Java. The Kotlin implementation leverages Kotlin's native coroutines and uses continuations.

It'd require a bit of engineering to get something working in native Java I'd imagine, even with the new JDK Structured Concurrency API offering you a coroutines alternative.

On the other hand, "tailrec" is a keyword and implemented as a compiler optimization.

The closest I've seen in Java is a neat IntelliJ plugin that has a transformation to convert recursive method calls into imperative loops with a stack frame.

This transformation and resulting tool was the result of someone's thesis, it's pretty cool:

There is a niche for small, mobile handhelds, with companies such as Retroid and Ambernic making devices with smaller screens. Interestingly even in this niche the proportion of truly mobile vs. portable is seeing the same continuing shift to larger, more powerful handhelds over time.

It seems in all categories people tend to purchase devices with larger screens. I wonder if this is caused by the nowadays much larger proportion of adults using these devices, where the Gameboy, etc., we're seen more as children's toys - meaning smaller form factors and screens might have been a better fit.
Political problems can be solved with technical solutions. Take the problem of food insecurity in third-world countries as an example. It's a hard problem to solve because transporting food overland via unpaved roads through politically unstable areas is expensive and dangerous. Long-term, using highly-productive first-world agribusiness to feed the third-world will fail, because no matter how cheaply agribusiness can produce food the transportation costs will make the whole enterprise cost prohibitive. This is a political problem: we can easily produce enough food to feed the entire world, but we can't get that food to the places where it is most needed due to political instability. But it's a political problem with an engineering solution. If the tools and techniques needed to efficiently grow food are cheap and widely available, farmers in politically unstable areas can simply grow their own food without a dependence on far away agribusiness. GMO crops crafted for nutritional value and hardiness, easily accessible guides on farming best practices, weather forecasting, irrigation, fertilizer, pesticides, financial markets to hedge against risk, cheap tools and machinery; these are all unsolved or partially solved problems. Whenever someone comes up with a "good new thing" that improves the SOTA in terms of value per dollar in one of these areas, we get closer to solving the political problem of global food security.

If political realities prevent us from solving problems, then we can either change the political realities or create new solutions. Individuals generally can't change political realities, but they can create good new things that work around them. So it is good advice.
> The fact that you're treating it like trade school is your problem, not the university's.

When (for many people) going to college almost necessarily means accruing 5-figure to 6-figure debt at the infancy of their careers, they sure as shit better have some sort of marketable skill to justify and remedy that debt coming out of it.

I understand the sentiment of higher education being useful for broadening one's horizons, challenging you, teaching you how to think etc; but you should be arguing in the _positive_ for these things to be available to everyone without a paywall.
Thanks for the detailed feedback! I see what you mean about maintaining overall luminosity—I'll look into adjusting the noise effects to preserve brightness better. "Dust" darkening too much is a great point, and I'll look into it as well.

I'll also check out Photoshop’s "Texturizer" for inspiration—adding a quick "canvas" effect sounds like a great idea.

The design of spans does not make assumptions about this however. `ref T` pointer inside the span can point to any memory location.

It is not uncommon to wrap unmanaged memory in spans. Another popular case, even if it's something most developers not realize, is readonly spans wrapping constant data embedded in the application binary. For example, if you pass '[1, 2, 3, 4]' to an argument accepting 'ReadOnlySpan<int>' - this will just pass a reference to constant data. It also works for new T[] { } as long as T is a primitive and the target of the expression is a read-only span. It's quite prevalent nowadays but the language tries to get out of your way when doing so.
> Startups are often unprofitable despite having a good product.

There are lots of reasons a company can be unprofitable. Just having a "good product" does not mean there is a "market demand" for the product.

> Large companies have an easy time of making good products profitable, but a difficult time in developing good products from scratch.

You accidentally have made my point for me again. Why should this at all be the case? What natural economic factors lead to this outcome?

> that is dominating a market would not be acquired for a small amount of money

You could also just compete with them. Market domination is one of the factors in determining if an illegal monopoly exists.

> Google makes the majority of its money on ads.

So owning platforms that deliver ads is an important part of market lock up.

> brainless to ignore YouTube, Waymo, Pixel, Cloud,

All things that deliver ads or gather user data for the purposes of advertising, yes?

> All of these would be unicorns if they were independent companies.

With the exception of their cloud.. they all used to be independent companies.

That there are attributable reasons for the outcome is not interesting, why this illegal outcome is not prosecuted is.

> things like solar and batteries.

Magnets too - let's just go magnets everywhere.

Reality is solar isn't viable everywhere. And it's not optimal to put it in places where you use the sun to grow food.

We should follow a holistic approach.

* Wind where it's windy.

* Solar where it's sunny - ideally on buildings/away from farms.

* Hydro where possible.

* Nuclear where it makes sense, i.e. stable geography, low occurence of natural disasters, lots of land.

* Some natty gas plants for overflow - not saying commission new ones or prioritize natty, but it's sensible to utilize existing peaked plants.

I'm not a big fan of large scale battery storage solutions, but they can work sometimes. I think they're more sensible for residential/commercial use and, when paired with solar, can really help add robustness to the grid. But, for mega energy storage, I think hydro based solutions are more sensible.
> why is it so hard for society to consider treating smartphones, social media, and highly-immersive video games like MMORPG's, with essentially all of the same effects, the same way?

I agree with you. I would consider social media and games addictive. It's just that the SMS app on my phone isn't addictive. Telegram app, the Photo app also isn't.

> This example shows how it works for one trait, Debug, but what if you have a type that (might) implement multiple traits A, B, and/or C? It isn't clear to me if that is possible, unless the type implements all of those traits.

Yeah, you can do the same trick if you care about types that implement all of A, B and C.

> What I'd like to do is have some base trait object and query it to see if it supports other interfaces, but also not have to have stub "I don't actually implement this" trait impls for the unsupported ones.

Currently this is not possible, though it might be possible in the future once Rust gets specialization. With that you would basically be able to write the "I don't actually implement this" stub automatically. The catch however would be that this can only work for `'static` types, since such specialization for non-`'static` types is unsound.

> I believe I understand that in rust this has not historically been possible because rust doesn't have inheritance, so, there can be only one vtable for a type, rather than an chain like you might have in c++.

The issue is kinda the opposite. In Rust types can implement any number of traits (even infinite!), so they would require an potentially an infinite amount of vtables if implemented like in C++, which is just not possible. So instead this is splitted from types and moved to trait objects, which allow to carry a vtable for one specific trait.
I agree with your comments about the large subreddits, but I also agree with Mistletoe that even many niche subreddits (or at least "midsized" subreddits) suffer from the same moderation problem.

Namely, once a subreddit becomes popular or has basically "the default" subreddit name, it's extremely difficult to just start a new subreddit if you don't like the moderation on the old subreddit, because it's so hard to get people to know about or move to the new subreddit. There was some drama years ago where some r/lgbt mods went on a major power trip, which caused other folks to start the r/ainbow sub, but still most folks go to the lgbt reddit as it's what comes up first if you just search for "gay subreddit" or similar.

You say "because moderators are beholden to a smaller community", but that's the point - mods aren't really beholden to anyone at all, as it's not like electing mods is a democratic process. Note nor do I think it should be, as being a mod is a ton of grief and labor that people donate for free. But I do think Reddit could make it a lot easier and "fairer" if people wanted to "fork" a subreddit if people wanted to discuss the same topics with the same community, just with different moderation rules.
The language of the corporate meeting room in America is also a lot more casual than in Europe. It has zero bearing on actual professionalism (defined, “ the competence or skill expected of a professional”) given the results of American corporations (or the strong safety record of US pilots). So, while I can literally understand your point, I can’t see why it’s material to anything.
Nice looks useful
This looks neat, but the problem with all these nostalgia fueled projects is that if you use it seriously you’re basically LARPing being in a kinder past. Eventually it just gives an empty feeling, and you long for days when interfaces didn’t just look like this for fun, it’s because that’s what they simply were, and this was the state of the art. But you can never go back to those days.

My entire point is that these things are seldom so black and white as put forward. The US administration has a self serving answer, but so do the French and this anonymous scientist. Which do you think is less professionally damaging for a European, being denied entrance due to views on American politics or being denied based on mishandling of classified material?

In an ideal world, I would prefer to see any mishandling of classification prosecuted, that seldom is how it works.

Until we solve the storage problem, the manufacture of batteries required to store solar power at night and during other low generation times is actively doing harm even without failing.

I don’t think this invalidates your point but I do think it is incredibly important to recognize that environmental harm done slowly over time is no less impactful than that done by a disaster.
