>What's missing in that system is a way that money is entering the system.

Or maybe not enough money soon enough, and at this scale that could be more of a disaster than it had to be.

So far it's not looking like a business boom much at all compared to the massive investment boom which is undeniable, and that's where a good amount of remaining prosperity is emanating from.

If you were a financial person wouldn't you figure there were a lot bigger bonuses by getting involved with the amount of cash flow being invested rather than the amount resulting from profits being made in AI right now?

> Again, you're arguing here on the basis of quality.

You have to have a minimum threshold of quality for speed to mean anything. If not well, I can outperform math calculations even if you have a calculator. My answers might be nowhere near correct and I might just yell "zero" in response to everything, but it will be very fast!

Or have a made some bad assumption that quality isn't relevant at all? That you're arguing fat void of all correctness? If so, I'm not sure there a meaningful conversation to have at all

But instead if there's any measure of quality that must be satisfied, even if the bar is on the floor, then reread my comment again. I'm afraid you're reading what you want to read rather than what I wrote. You're going to have to work with me here as I can't beam my thoughts directly into your head nor am I willing to write a novel in reply. I've already been quite verbose

I don't know about this particular case, but, generally... bad actor subreddit moderators have been an occasional thing for well over a decade.

And it's also been widely known for that long that Reddit is an influential venue in which to take over a corner -- for marketing or propaganda.

What's an equal concern to me is how insufficiently resilient Reddit collectively appears to be, in face of this.

A bad actor mod of a popular subreddit can persist for years, visibly, without people managing either to oust the mod, or to take down the sub's influence.

(Subreddit peasants sometimes migrate to a new sub over bad mods, but the old sub usually remains, still with a healthy brand. And still with a lot of members, who (speculating) maybe don't want to possibly miss out on something in the bad old sub, or didn't know what's going on, or the drama they noticed in their feed wasn't worth their effort to do the clicks to unjoin from the sub in question.)

Do they actually say in the TOS that they will delete them? If they do, do they say immediately? How immediately? Right away or, perhaps, 1 month? Unless specified in contractual documentation, words like "immediately" or "soon" do not have any single definition, which allows them to stretch it without technically being in breach of contract. Not to mention that often times, governments mandate data retention for so-and-so amount of time, so the companies are legally required in such cases to keep the data even if they, miraculously, desire not to.

Interesting, but not so "exotic".

On Earth, we have a mix of S_32 (95%), S_33 (1%) and S_34 (4%) approximately. https://en.wikipedia.org/wiki/Isotopes_of_sulfur

In the Moon, there is less S_33. So it's a different mix, but not a mix that includes a lot of unusual things, just more of the usual things.

> The fact that iOS safari supports SO many lifecycle features except BeforeInstallPrompt is just so frustrating.

BeforeInstallPrompt is non-standard. They removed it from the specification because Mozilla had no plans to support it and Apple wouldn’t commit either.

Here’s the discussion:

> There is also some disagreement on the a `BeforeInstallPrompt()` event (BIP). Despite BIP having been in the spec for a few years, neither Safari nor Firefox have opted to support it. As it stands, Mozilla does not plan to support BIP. We are unsure what WebKit's plans are - @hober maybe could let us know? If WebKit doesn't plan to support it, then we should probably remove it from the spec.

— https://lists.w3.org/Archives/Public/public-webapps-github/2...

So yet again, this is a case of Google wanting something, Google implementing it unilaterally, Google not being able to convince any other rendering engine to implement it, then the non-standard, Blink-only behaviour is being presented in situations like this as if Safari alone is failing to support a standard.

Web standards are not whatever Google wants. They are arrived at through consensus.

Are you planning to write something up about it? It would be interesting to hear the other side that you’re hinting at.

It’s also not clear to me if the person who wrote this article was paid for it or if they’re somehow affiliated with someone involved. It says they’re a “Fractional VP of Content”. I’m curious if you know more.

I saw the article about D4vd when it was popular enough to hit the front page- https://www.reddit.com/r/Music/comments/1nnlqan/singer_d4vd_...

The criminal case is an open investigation and also has been in the news lately: https://www.yahoo.com/news/articles/details-emerge-homicide-...

My significant other follows influencers thus I heard about the Paige Lorenze controversy/lore.

I wouldn't say either of them is "not particularly relevant" as D4vd is super popular among GenZ on tiktok and has 30 million listeners and 4 million followers. Paige isn't as big but she is a well-known WAG dating some tennis bro and has a successful clothing brand that sells to the genZ crowd.

Fortunately we learned our lesson with YAML. (/s)

I feel like I need to point out that this tool does not do, in any way, what the title claims. Parsing the output of the system profiler tool will not tell you whether your cable is "good", which in practice tends to mean that it supports the protocol the user cares about at that moment. For some examples: If you connect a Thunderbolt only cable to a USB4 only device, this approach will give you no information about why things are not working. If you connect a USB2 only cable to a Display-Port Alternate Modal display, this approach will not tell you anything about why your display is not turning on.

It appears that the phrase has multiple uses/meanings, with priority of definition going to Dunning & Kruger as far as I can find.

This is the earliest clear definition in the sense I was recalling that I can dig up:

"In its place would be substituted the concept of partial radical ignorance. The adjective “radical” is here meant to distinguish this kind of ignorance from the neoclassical concept of rational ignorance, which refers to a state of affairs in which knowledge exists that would improve our situation but that the expected cost of acquiring it exceeds the expected benefit. We thus choose not to know what is not in our interests to know. In contrast, radical ignorance refers to our unawareness of even the existence of relevant knowledge that we could know at zero cost."

This is why constantly trying to come up with new words that aren’t offensive is fool’s errand. There will always be people looking to comment on someone’s intelligence in a negative way. If people find the act of doing that offensive, the word choice really doesn’t matter. Making up new words every few years just creates new words for people to use in demeaning ways.

There are a lot of misconceptions and things being confused together in your post. For one complexity classes are related to decision problems, not algorithms. An algorithm does not have a complexity class, rather it's decision problems that belong to a complexity class. 3SAT is a decision problem that belongs to the NP-complete complexity class regardless of any particular algorithm that implements a solution to it.

Secondly, it's a common misconception that O(f(n)) refers to worst case complexity. O(f(n)) is an upper bound on the asymptotic growth of f(n). This upper bound can be used to measure best case complexity, worst case complexity, average case complexity, or many other circumstances. An upper bound does not mean worst case.

For example I often perform code reviews where I will point out that a certain operation is implemented with the best case scenario having O(log(N)), but that an alternative implementation has a best case scenario of O(1) and consequently I will request an update.

I expect my engineers to know what this means without mixing up O(N) with worst-case scenarios, in particular I do not expect an improvement to the algorithm in the worst case scenario but that there exists a fast/happy path scenario that can avoid doing a lot of work.

Consequently the opposite can also happen, an operation might be implemented where the worst case scenario is o(N), note the use of little-o rather than big-o, and I will request a lower bound on the worst case scenario.

This whole thing feels like a neat encapsulated example of how horrible the "Internet" has become. A bad actor with vested interest taking over a part of a website (Reddit) that is then used as a source of record (Google, LLMs), and bam, completely fabricated overviews of a brand/company are now all you see when you use the predominant search engine, because there are no alternatives.

All of this for what? Shareholder value? So Silicon Valley elites can get rich and force their shit ideas on everyone?

If you don't see this for what it is, and that is just pure rot of the major services that people use and rely on for their information needs, then you might be beyond helping. Everyone should be pissed that this is what the internet has become.

This reminds me of the AOL Time Warner merger. "Back in the day", America Online (AOL) had a valuation large enough to pull it off:

It was the largest merger in history when completed with the combined value of the companies at $360 billion.[0]

After less than a decade, once ISP's became a thing, the AOL part of the new company shriveled into nothing and was spun off. It still exists, in name if not anything recognizable to what it once was.

The concept of a "subsystem" in Windows has evolved since the operating system's inception when Windows NT was designed to support multiple operating system environments through distinct subsystems. Win32 subsystem, which features case-insensitive filenames and device files in every directory, and the POSIX subsystem, which supports case-sensitive filenames and centralized device files: Windows subsystem, the Subsystem for Unix-based Applications (SUA), and the Native subsystem for kernel-mode code were the main subsystems at first.

/SUBSYSTEM linker switch was used to specify the target subsystem at compile time, enabling applications to be compiled for different environments such as console applications, EFI boot environments, or native system processes.

In this nomenclature, WSL follows the original naming conventions (although SUA should have been called WSUA).

> Include them in cost comparisons.

Our point is that they aren't. Find a single study the fossil fuel industry funds, hell even accepts, that includes the longterm environmental and health costs. They’ll never agree it’s accurate. This ripples out to their proponents.

We have a US president touting “clean coal” in 2025. What else is there to say?

> User, relying on the published policy that Discord will delete ID directly after being used to to the age check [1] decides they wish to remain to have communication with their online friends uploads their ID.

This is the part where the user has to take at least partial blame. You have to be utterly stupid (or at the very least way too sheltered) to believe a statement like this from a company, especially when there are zero consequences to the company for lying about it or negligently failing to live up to their policy.

Cool read and and as an owner of Porsche 911 Carrera from 1988, I can both relate and not relate. I bought my 911 at 26 y/o in 1999: the car was 11 years old and had 135 000 km / 85 000 miles. I then used it as my daily for five years straight.

The year is 2025. I still have it (never had the heart to sell it) and still use it so now I own it since 26 years. This thing is rock solid reliable. It's certainly a bit manly to drive (no assisted steering and no ABS) but every time I use for something mundane (like going to the pharmacy or to pick my kid at school) I keep thinking "it's insane that this thing is so reliable I could still use it as my daily if I wanted to".

Now of course a Porsche 911 from the 80s ain't a Porsche 914 from the seventies but still: quite a different experience over 26 years (and my car is now 37 years old) from the experience in TFA.

Agree that it would have impact, but not the good kind.

The services that deal with CSAM would be flooded with false positives from the automated scanning. They would, in turn, have to find methods of short-cutting the assessment of these false positives so that they can actually function.

The real CSAM would be drowned out by family snaps of kids in pools, of teenagers sexting each other, etc. The ability of the relevant services to actually detect and catch real abusers would be severely hampered. Actual abuse would be caught less and more kids would be harmed.

Five minutes of thought leads to this obvious conclusion. Which implies that this was never about protecting kids in the first place. It's about controlling what people say, as always.

> humans decided they were "prime", i.e. most important, based on arbitrary considerations

No, not arbitrary considerations.

The term goes back at least to Euclid who investigated factorization of integers in his "Elements". He used the greek word "protos" that was later translated to Latin as "primus". It doesn't mean "most important", rather "first".

The idea is that primes are the "multiplicative building blocks" for other numbers, the "origin" or "first principles", because every integer factors into primes. When a mathematical object can be decomposed in some way, it is very natural to study the irreducible blocks, because many questions boil down to them.

Zoonotic origin reduces the risk of GoF research because understanding the underlying biology becomes more useful to address novel variants popping up in the wild (apart from other potential uses).

A poor analogy is suppose in 1800s humans encountered nuclear explosion near nuclear research lab. It could have human or natural origin. If natural then it is important for us to accelerate nuclear research with relatively lax regulations and develop countermeasures. If human origin, lack of sufficient regulation is a more probable cause.

The truth that a lot of people don't want to hear is that tests are insufficient to prove your code is bug free

When saying these words aloud (or even on HN) many will reinterpret them as "tests are worthless". It's hard to reorient to "tests are incomplete". I'm not sure why this is such a difficult concept to understand. Unless you're omniscient, how can they be complete?

People need to understand, you cannot measure anything directly. You are always doing so by proxy. If you do not know the limits of your proxy then you're only allowing yourself to be blind to foreseeable problems.

So, tests are hints, not proofs. They prove correctness in narrow areas, but not completely. Worse, you cannot test unknown unknowns. Which, as you suggest, is why dog fooding is such an important part of the development process. You aren't just a developer, you need to be a user and an adversary. You should try to see your programs from as many perspectives as possible. This too won't get you to full coverage, but it'll get you a lot further than just tests and it'll help you find what tests need to be created.

I of course agree that the player should not be able to overrule the GM. I don't think that was the situation here.

If you're playing an off-the-shelf campaign this is problematic. If the GM is creating the game as you go, then a good GM should be able work with the player to make this reasonable. The GM can always use GM-power to prevent a player from doing something, even if it involves a literal hand of God reaching down to stop them.

A conversation with the player beforehand to make sure you're on the same page about this sort of thing would go a long way. Let them know under what circumstances you're willing to allow them to use whatever the power is. Let them know the consequences if they don't follow those rules.

Unlike with ChatControl, a D&D game is a situation where the necessary trust is able to exist.

An example: agree the player character is some trickster djinn sent from another plane to learn to be a human and how to trick people. They have immense cosmic powers of life and death, but as part of being sent over, they can only use the power for immediate comedy. Violations result in the djinn getting yanked back to their plane and disincorporated.

Boom done. Now you have a massively OP character that can only use their power in humorous situations that don't affect the storyline, and if they try to abuse that then that's instant-death.

you have to do the same on the server side and your database, if you have one. the API is just data too. you don't keep all your application state in you database, do you?

i don't know what kind of application you have in mind, but in mine the frontend state and the backend state are entirely different things. the only thing that needs to be kept in sync is the data itself. and that's easier than the whole frontend state which is a lot more complex. in most cases you treat the backend like a database itself. there is n additional state to be kept in the backend, than what goes into the database. at least with all the applications i ever built. i am sure there are other applications that are more complex, and i may change my mind when i get to work on one, but i believe most applications are CRUD, and complex UI state is only in the fronted, data state in the backend/database,

All you have is trust. No evasion, those are the rules of the road as it stands in the jurisdiction of US web properties.

If your point is "I don't like the law of the jurisdiction and its outcomes," that is a feeling and a choice, but the fact remains. You can either change the law or change the feelings. Again, participation is a choice and optional, and the status quo is unlikely to change.

Beyond my pay grade but I'll take a stab (meaning I'm talking out of my ass).

Some in fact have but the majority? Probably laziness, but laziness is just misaligned incentive-goals.

Communities have very little incentive to de-reddit. It's actually a huge amount of work and they gain almost nothing directly.

Separately, I was thinking you know HNews is pretty immune to this problem because we don't have a central theme or something, right?

But no, that just means I can't see how I'm being monetized is all. Blind leading the blind.

The US Supreme court ruled the other way as recently as 1989: https://en.wikipedia.org/wiki/Texas_v._Johnson

It was 5-4, but the majority included the venerable Justice Scalia.

How do we reconcile past SCOTUS decisions, and the pretty plain wording of the constitution's first amendment, with Mr Trump's decision? I mean, we as a country have been pretty happy with his decisions in other hotly contested matters. I supposed we can be happy with this one.
