But I don't think it's terribly useful; there are plenty of things that you could do that the people who coined the term would definitely not agree with.

Instead of inheritance, I could just copy and paste lots of different functions for different types. This would be different than inheritance but I don't think it would count as "composition", and it's certainly not something you should "prefer".

Tell you what, here's a story from my last job.

I was hired on to help run these experiments with a machine they were trying to perfect. They wanted to do all this stuff with running two machines in parallel, dumping the refuse from one into another machine, all kinds of silly stuff.

I looked at it and in a few minutes I sketched in my notebook a solution to their problem that would achieve the maximum theoretical yield without all these wacky experiments.

But then what would be my job? I was hired to run these experiments not solve their whole problem in 5 minutes. So I didn't tell them. I was getting paid so i didn't care if they were wasting time. I'm a smiley little trans woman anyway, they wouldn't have listened. I did work out the math though on my own.

A few months later, a team of phds at a university we were working with hit on a rudimentary form of the same idea, so at that point I revealed to the boss, oh, look I've worked out the math for that already. And I wrote up the code, and we hit the maximum theoretical yield and it ran 100x faster computationally, and i got a pat on the back. But the reason they listened was because a man with a degree said it.

Why would I bother giving them ideas if they won't listen anyway? If i had given them the answer months earlier, I would not have gotten any kind of bonus even in the unlikely event that I had been taken seriously.

So now of course youre all telling me im insane, and thats fine because honestly I have no incentive to give you answers ahead of time. Go suck eggs. Figure shit out on your own.

What I like about the modern¹ approach (interfaces + composition) is that it cleanly untangles polymorphism from behaviour-sharing.

When you inherit from a parent class, you have to be careful to only override methods in ways that the parent expects, so the parent's invariants aren't broken². There's a whole additional set of keywords (private/protected/final) meant to express these parent-child contracts. With interfaces + composition, those are unnecessary: You can compose an object and use it however you want; then, if you want the wrapper object to uphold the inner object's contract, you can additionally implement an interface to formalize that. The behaviours you use and the polymorphic guarantees you make are totally separate.

Inheritance mixes these ideas together and ends up worse for it. Not only the modern approach is simpler, it's more powerful: (1) Polymorphic extension (i.e. extending a polymorphic parent class at runtime) is doable, and (2) multiple inheritance is a non-issue.

[1]: I call it "modern" because newer languages like Go and Rust have eliminated inheritance in favour of exclusively using interfaces/traits.

[2]: See the fragile base class problem.

An upsell is a FUCKING AD and has no business existing, period.

Nothing should appear on a user's screen that doesn't add value for what the user is trying to get done. This is really, really simple. If you are Microsoft, and you are thinking about whether something should appear on the screen, you should be thinking "Does this advance the user's goals?". If you are instead thinking "Does this advance Microsoft's goals?", then you are doing it wrong.

The same applies to automagically configuring everything to use the cloud (good for Microsoft, usually bad for the user). And, as a special case of that, requiring the user to use a cloud-based account to log into their own local computer.

This is going to take some serious reading.

I've been struggling with a related problem over at [1]. Feel free to read this, but it's nowhere near finished. I'm trying to figure out how to do back references cleanly and safely. The basic approach I'm taking is

- We can do just about everything useful with Rc, Weak, RefCell, borrow(), borrow_mut(), upgrade, and downgrade. But it's really wordy and there's a lot of run time overhead. Can we fix the ergonomics, for at least the single-owner case? Probably. The general idea is to be able to write a field access to a weak link as

sometype.name

when what's happening under the hood is

sometype.upgrade().unwrap().borrow().name

- After fixing the ergonomics, can we fix the performance by hoisting some of the checking? Probably. It's possible to check at the drop of sometype whether anybody is using it, strongly or weakly. That allows removing some of the per-reference checking. With compiler support, we can do even more.

What I've discovered so far is that the way to write about this is to come up with real-word use cases, then work on the machinery. Otherwise you get lost in type theory. The "Why" has to precede the "How" to get buy-in.

I notice this paper is (2024). Any progress?

I used an online tariff calculator and it said it should be 15%.

I got tempted by one of the Brymen/EEVBlog multimeters. There's still stuff on US gov sites (and tariff calcs) suggesting we've a free trade agreement with Australia. The reality is that a 40% tariff is likely to be applied, and the worst case is that someone decides that the copper tariff also applies and in lieu of a declaration of the amount of copper the US gov just assume the whole thing is solid copper. The sad part is that puts a brand new, made in RoC multimeter (BM2275) in spitting distance of a used, working 33401A but not an assembled-in-the-usa-with-global-components Fluke.

Lesson learned: don't trust tariff calcs and assume the worst case. Even if you order something when tariffs have been dropped you're still at risks for broad sweeping tariffs to come into effect by the time your item arrives at a US port.

Moving forward: big companies are far better able to deal with this tin pot dictator chaos, let them handle importation if you can. DigiKey (ugh), Mouser, and Newark all show the tariff as a line item. I'm quite sure at least one of them is fudging COO and all three have some remaining US inventory of some items so there's still some entirely legal tariff avoidance.

Likewise AliExpress choice involves shipping to what I suspect is AliExpress' bonded warehouse and they handle the applicable tariffs. I've recently decided to learn how to solder and there's still plenty of 99 cent crap available from AE if you're willing to (ab)use the new customer discount.

It is also that, at 12 years of age, that kid may have had enough of harsh life lessons already, like when he was promised something instead of being rewarded on the spot and later it turned out he was just being tricked. I imagine that something like that may have had a much more direct impact on his OP described decision - that hard earned "street smarts" keeping him grounded in his (undesirable) reality.

That lecture is by a doctor who had widely discredited views on cancer, often cited as an example of quack, pseudoscientific claims on the topic.

His claims, specifically on cancer, were widely and roundly rejected by the scientific and medical community. This is not a controversial statement, either - his supporters proudly proclaim that his views are rejected by the vast majority of experts which, in my opinion, pretty much sums it up.

I highly recommend people avoid falling into this dangerous rabbit hole.

I’m actually interested in solving the documentation problem. Imo we as engineers are thinking too small and keeping docs as this side thing sounds like a recipe for irregular maintenance. Instead, what if docs were more like live blueprints of running systems? We don’t want obvious stuff documented like there is a function called foo, but foo’s relationship to other parts of the code and its runtime characteristics seem important. I think I’m imagining a different form of documentation that is tied with observability but that’s because I feel it’s information that’s far away from code currently and ideally I’d like all information derived from a piece of code to be available at the same place.

Probably slightly off topic but I’d be curious to hear what other people want out of automated systems in this space. I have so many half baked ideas and would love to hear what’s others think/want.

Foraging for soldiers included plundering and pillaging the local population. They could also just have easily hunted the local villagers' livestock as a source of meat which they could then salt and preserve for food on the march.

The article I listed explained in detail how Roman soldiers carried out the full process of turning grain into flour and then baking bread in their encampments. You don't think they could have managed the slaughtering of livestock?

But besides that, there were plenty of forests around (which they used to gather firewood, as mentioned in the article). Those forests absolutely would have contained deer and other game they could hunt and preserve.

If a legit user accesses the link through an <img> tag, the browser will send some telling headers. Accept: image/..., Sec-Fetch-Dest: image, etc.

You can also ignore requests with cross-origin referrers. Most LLM crawlers set the Referer header to a URL in the same origin. Any other origin should be treated as an attempted CSRF.

These refinements will probably go a long way toward reducing unintended side effects.

Agreed, but

> The consumption of "stuff" contributes to GDP, which is one of the first things people use to correlate to quality of life.

It's one of the first things governments use to correlate to quality of life, and imo it's a good way to get away with papering over inequality. A country's GDP can be stable or slowly growing and it won't be in recession, and yet much of that GDP can be produced by one generation of people who are in a class that's multiple orders of magnitude wealthier because the newest generation of people has to pay them to have a roof over their head and subsidize their retirement. The GDP comes from the appreciation of their property value and the rental income, while a massive proportion of working age people are just able to consume and work, largely for those same people. Very wildly different qualities of life even below what Mag World would consider Rich, maybe not in the moment when someone can but themselves some literal or metaphorical candy, but in terms of viable upward mobility and precariousness long-term.

In order to buy the house I live in the basement of, not even owned by a much older generation person in this case (seemingly a single mom, but an investment banker afaik), I would need to be able to sustain a $2m+ mortgage and come up with a $400k+ down payment, it will never be possible, and even though I never wanted that for my future, it's depressing that it's just laughably and insanely out of reach, GDP kind of hides that this is the case for many.

An agent acting on my behalf, following my specific and narrowly scoped instructions, should not obey robots.txt because it's not a robot/crawler. Just like how a single cURL request shouldn't follow robots.txt. (It also shouldn't generate any more traffic than a regular browser user)

Unfortunately "mass scraping the internet for training data" and an "LLM powered user agent" get lumped together too much as "AI Crawlers". The user agent shouldn't actually be crawling.

AWS really needs to focus on simplifying their offerings for the next generation that is not very "computer savvy" for starters. You can host a website on ec2, you can also host it on elastic beanstalk, you can also host it on lightsail? See the problem? Instead of making us focus on how to adapt to your services, why not focus on how you can adapt to the customer needs. Introduce something called AWS WebServer or something and deprecate everything else except EC2. let people run their docker and lightsail and static hosting from this Amazon WebServer service. Do the same for databases. Why offer a separate Amazon Aurora postgres and an amazon RDS. Offer a service called Amazong DB and let the user decide if it is posgres, server oriented, serverless from there. Let it also handle dynamoDB

After a stroke I've been using a software version of the half qwerty keyboard, it works quite well and you dot need special hardware, but you don't have integrated mouse, you can achieve that using ahk on windows and Karabiner Elements on Mac. the big advantage is that you keep using the same qwerty layout but mirrored, this makes it easier to learn. http://half-qwerty.com/

Haha, it's all good, and it gets fun when you hit the South Island / Te Waipounamu dialect of Māori where a maunga is a mauka, and sky is raki not rangi, but both variants are still used.

A classroom at my childrens' primary school was called Maungatere (floating mountain) after a nearby mountain which is now called Maukatere, same meaning.

Likewise the local iwi/tribe in my area is known both as Kāi Tahu and Ngāi Tahu, and there's a town in North Canterbury called Rangiora, which translates to, roughly "Good sky", while the 3rd largest island of Aotearoa New Zealand is called Rakiura / Stewart Island, Rakiura meaning "Glowing sky".

And our tallest mountain Aoraki / Mount Cook used to be Aorangi / Mount Cook.

And to be fair, "Mounga" is a decent rendition of how you pronounce "Maunga".

Yes it is, as it is about the semantics of type hierarchies, not their syntax. If your software has type hierarchies, then it is a good idea for them conform to the principle, regardless of whether the implementation language syntax includes inheritance.

It might be argued that CLU is no better than typical OO languages in supporting the principle, but the principle is still valid - and it was particularly relevant at the time Liskov proposed it, as inheritance was frequently being abused as just a shortcut to do composition (fortunately, things are better now, right?)

This is needed even if you are IN the Apple ecosystem. I don't want to upgrade my phone to the latest half-baked iOS version, so Apple purposefully degrades the functionality of my new AirPods 3. Siri won't switch noise cancellation modes, I can't see the battery status, they get relegated to the "generic bluetooth device" section, and even the battery widget will display three identical headphone icons for headphones and the case.

How do I know this is done purposefully and not just because AirPods 3 are so new and different from AirPods 2? Well, macOS has been neglected of late, and Apple didn't find the time to break things there, so Airpods 3 work with macOS just as well as Airpods 2 did — switching modes, battery status display, etc.

It's very disappointing, and not a great customer experience.

1. I am confused, did copyright holders not amused by archive.today etc, intentionally serve CSAM material when they detected a visitor was in fact archive.today scraping one of their pages? It seems they are on the hook for more than just "inaccurate reporting of CSAM materials".

2. Is it a legally allowed tactic for copyright-luvva's to intentionally seek out CSAM content online, and then submit those URL's to sites like archive.today? Which entity is at greater legal peril, the one that aids the distribution of CSAM materials by intentionally having a site like archive.today archive CSAM content, or archive.today unintentionally being tricked into archiving CSAM content?

3. Everyone has traumas, of one kind of another. Each deals or tries to deal with them in their own way. Suppose a victim of crimes (still unpunished) finds or is informed of the presence of evidence online, and suppose this victim (regardless of how representative) finds the preservation of this evidence more important than the humiliation associated with it, how (in)just are laws that blanket suppress CSAM material? To give a more vigorous example: imagine you were raped by some no-yet-fallen UK nobility, and you are made aware of the presence of this evidence on some royal FTP server (or whatever), and you succeed in having archive.today "notarize" this evidence (independently from legal channels, since theres a suspiciously low amount of nobility being convicted, in contrast to your personal experience). These rules for supressing CSAM can be wielded as a sword precisely against those who fell prey to perpetrators...

Umm, no? Absolutely not. If you lie to someone in conducting a business transaction, that is textbook fraud. You can tell them "sorry, I can't share that information about our business process to protect trade secrets". You absolutely cannot say "we do it this way" when you don't do it this way. It doesn't matter if the output is the same.

You don't know, and don't need to know, what details mattered to your customer. If they're deciding between two different vendors, and you told them one detail of your process that happened to help them decide to go with you, it doesn't matter what that detail was. You defrauded them.

The AI vs human detail of this specific case is an irrelevant distraction. Imagine choosing between two cloud hosting services, one of which says it is powered by solar panels, the other says it's powered by the regular grid. In reality, both are powered by the grid. The customer never specified it, but environmental impact ended up being the deciding factor for them going with the first company. They were just defrauded.

Imagine two companies selling Widget X, which a buyer wants to buy to use as a part in their product. Both companies manufacture Widget X in China, but Company A says they make it in Mexico. A customer decides to order from Company A because one of their executives is Mexican and a bit patriotic. It doesn't matter that that's the only reason and it's frankly not a very good one; they were still defrauded.

If, as the original post claimed, they told their customers they were using AI, and they were in fact having a human hand-typing the summaries, that's fraud. It's insane that anyone would try to defend this.

Aside from game dev, Rust is being used in quite a lot of green field work where C++ would have otherwise been used.

Game dev world still has tons of C++, but also plenty of C#, I guess.

Agreed that it’s not really behind us though. Even if Rust gets used for 100% of C++’s typical domains going forward (and it’s a bit more complicated than that), there’s tens? hundreds? of millions (or maybe billions?) of lines of working C++ code out there in the wild that’ll need maintained for quite a long time - likely order decades.
by Spivak | 2025-11-16 04:02:33+00:00
I don't understand the problem with your first example. The __init__ method isn't special and B.__init__ is just a function. Your code boils down to:

def some_function(obj): obj.prop = 2 class Foo: def __init__(self): some_function(self) # or really just like class Foo: def __init__(self): self.prop = 2

Which like, yeah of course that works. You can setattr on any object you please. Python's inheritance system ends up being sane in practice because it promises you nothing except method resolution and that's how it's used. Inheritance in Python is for code reuse.

Your examples genuinely haven't even scratched the surface of the weird stuff you can do when you take control of Python's machinery—self is just a convention, you can remove __init__ entirely, types are made up and the points don't matter. Foo() isn't even special it's just __call__ on the classes type and you can make that do anything.

It does add up though.

1. Ticket 2. Feature branch 3. Write unit test 4. Periodically merge from main. 5. Implement to get tests to pass 6. Push changes 7. Create PR 8. Wait for PR feedback 9. Address feedback and repeat 10. Close and merge PR 11. Automated CI deploy 12. Integration testing as needed 13. Close ticket 14. Include in next prod release

All of these are good things. But the overhead is significant. And there may be times when you want to do spikes that forgo some of these.

Does any CEO actually use their own company's products?

The richest and most "powerful" people still have meat-based assistants do all their shit: Take their notes, check their calendars, make their appointments, toast their bread..

And it shows: This is how you get features like "Edge Light" and an Invites app before fixing basic functionality that the peasants rely upon. Like how we get the weird iOS Journal app even though Notes could have done all that if they had improved it a bit.

Steve Jobs was probably one of the few people in charge who actually used his company's own products. You need someone who's annoyed with the status quo enough to make a company to solve it, not just someone elected by a board.

I would love to see a project that rebuilds the Emacs UI but keeps the underlying core to give it a modern facelift, some things in emacs blend together and are a pain for my eyes to figure out whats what. It would be nice if the UI was modernized but the core was left as-is. I'm reminded of some of my favorite editors that are niche being Lisp related ones, where if you held down ctrl it would show you shortcuts in the UI itself and what they lead to. I also always enjoyed Racket's import arrows and other small things that are visually amazingly impressive despite being so simple.

The story is about “new applicants” and positions with no access to classified material. It is not illegal to share unclassified material, which is why DHS was having NDAs passed around.

> DHS said it was "unapologetic" about its drive to root out leakers. "We are agnostic about your standing, tenure, political appointment, or status as a career civil servant - we will track down leakers and prosecute them to the fullest extent of the law,” a DHS spokesperson told Reuters.

Maybe that’s true? I think HN was ok with this because it felt like a rational reaction to bringing guys like Big Balls into the SCIF.

The intent sure comes through (despite your attempts to conceal it), the reasoning doesn't. And it continues not to, not the least because of the desire for superiority relentlessly taking over you, muddying your rationale with persistent smug mockery and creative interpretations. So unfortunately no, I'll have to kindly refuse your request to respect all this.

> maybe AR/VR

I dunno, have you tried an Apple Vision Pro? It's actually a pretty phenomenal product for V1. I think really all they need to do is: (1) hit retina-tier PPD (pixels-per-degree) and (2) manage the weight, (3) do everything they're already doing, and I'm sold as a replacement for TVs & Desktop monitors.
