Angular momentum has energy x time units.

These unit equivalences have to be carefully interpreted. Like when things are multipled, are they in the same direction? Torque has the same units as work: force x distance, i.e. energy. But the force is perpendicular to the distance; it's completely different, and not a simple scalar value: torque is a vector with an orientation in space. Moving something against friction over 10cm, and using a 10cm bar to apply leverage, are entirely different.

Not sure why you're being downvoted, that was my exact issue. I only had a 128 GB iPhone 12 though and System Data had eaten up over 60 GB. As I cleared off more apps and data it would just eat up the excess.

The internet seems full of various wild fixes, but I could afford an upgrade so saved myself the hassle of futzing.

This is one of those wicked language design problems that comes up again and again across languages, and they solve it in different ways.

In Haskell, you can't ever check that a type doesn't implement a type class.

In Golang, a type can only implement an interface if the implementation is defined in the same module as the type.

In C++, in typical C++ style, it's the wild west and the compiler doesn't put guard rails on, and does what you would expect it to do if you think about how the compiler works, which probably isn't what you want.

I don't know what Rust does.

Those may be some amazing games you listed but none of them scratch the itch that some folks have for twitchy NES games. For some reason, modern indie developers never try to emulate the tight, twitchy, highly responsive controls of NES games. Instead, they go for floaty, slow acceleration-based, more forgiving controls.

The puzzle games in your list have no equal though. The NES is pretty light on puzzle / adventure games, though it did receive really nice ports of the MacVenture games (Deja Vu, Uninvited, Shadowgate) as well as Maniac Mansion, and it has a couple of unique ones with Nightshade and Solstice that blend in a bit of action while remaining primarily adventure games.

Reuters reports (https://www.reuters.com/business/retail-consumer/microsoft-e...) "CEO Nadella revealed for the first time that Microsoft now has 15 million annual users for M365 Copilot, the $30 per month AI assistant that is Microsoft's main offering for business users." so in theory that's $5.4 billion in revenue.

I don't understand what has changed here.

AI is just branding. At the end of the day it's still just people using computer software to do stuff.

There is going to be a person who did a thing at the end of the day -- either whoever wrote the software or whoever used the tool.

The fact that software inexplicably got unreliable when we started stamping "AI" on the box shouldn't really change anything.

Nonsense. I have ran an experiment today - trying to generate a particular kind of image.

Its been 12 hours and all the image gen tools failed miserably. They are only good at producing surface level stuff, anything beyond that? Nah.

So sure, if what you do is surface level (and crap in my opinion) ofc you will see some kind of benefit. But if you have any taste (which I presume you dont) you would handily admit it is not all that great and the amount invested makes zero sense.

Almost all developed economies are running into a fertility crisis right now, with labor shortages already appearing in the frontrunners of the trend, such as Germany.

Human work is going to cost more in the future, and immigration from countries such as Thailand or Vietnam is already slowing down. Even a mediocre robot will be sought after if it is the only choice you have.

no shared lineage. Cura and Kiri started around the same time (2011/2012), but as completely separate projects. Cura is a C++ desktop app and Kiri has always been 100% browser-based (no cloud, all computation in the browser sandbox). the licenses are different, too. Cura/Prusa/Orca are GPL based and Kiri is MIT.

^ This meme is from 10+ years ago when Scala was at the peak of its hype driven by the FP craze. Nobody seriously writes cryptic-symbolic-operator code like that nowadays. Scalaz, the FP library most notorious for cryptic operator/method names, hasn't been relevant for many years. Today everyone uses Cats, ZIO, or plain Tapir or Play, all of which are quite ergonomic.

Two things:

I've read studies saying that most drivers don't brake at max effort, even to avoid a collision. This may be at least one of the reasons that Waymo predicted that an attentive human would likely have been going faster than their car at the moment of impact. I've got a good idea of my fun-car's braking performance, because I drive it hard sometimes, but after reading that I started practicing a bit with my wife's car on the school run, and... Yeah: it's got a lot more braking power than I realized. (Don't worry, I brake hard on a long straight exit ramp, when no one's behind me, a fast slow-down is perfectly safe, and the kiddo loves it.) I've now got an intuitive feel for where the ABS will kick in, and exactly what kind of stopping distance I have to work with, which makes me feel like a safer driver.

Second, going off my experience of hundreds and hundreds of ride-share rides, and maybe thirty Waymo journeys, I'd call the best 10-15% of humans better drivers than Waymo. Like, they're looking further up the road to predict which lane to be in, based on, say, that bus two blocks away. They also drive faster than Waymos do, without a perceptual decrease in safety. (I realize "perceptual" is doing some work in that sentence!) That's the type of defensive and anticipatory urban driver I try to be, so I notice when it's done well. Waymo, though, is flat-out better, in every way, than the vast majority of the ride-share drivers I see. I'm at the point where I'll choose a Waymo any time it'll go where I'm headed. This story reinforces that choice for me.

I also terribly regret the retirement of 4.1.
From my own personal usage, for code or normal tasks, I clearly noticed a huge gap in degraded performance between 4.1 and 5.1/5.2.

4.1 was the best so far. With straight to the point answers, and most of the time correct. Especially for code related questions.
5.1/5.2 on their side would a lot more easily hallucinate stupid responses or stupid code snippet totally not what was expected.

For the models themselves, less so for the scaffolding, considering things like the long running TPU bug that happened, are there not internal quality measures looking at samples of real outputs? Using the real systems on benchmarks and looking for degraded perf or things like skipping refusals? Aside from degrading stuff for users, with the focus on AI safety wouldn't that be important to have in case an inference bug messes with something that affects the post training and it starts giving out dangerous bioweapon construction info or the other things that are guarded against and talked about in the model cards?

Navy v. Egan (1988) acknowledges a due process protection but limits it to procedural due process, not review of the merits of the clearance determination (i.e., the due process protection does not extend to substantive due process.)

Subsequent cases (mostly at the Federal Circuit, I can’t find the Supreme Court getting involved much since) like Cheney v. DOJ (2007) and Cruz-Martinez v. DHS (2020) have developed what that requires.

For cases outside of government employment, though the decisions so far are only at the trial level, Perkins Coie LLC vs. DOJ (2025) and Zaid v. Executive Office of the President (2025) are worth checking out in this regard.

This seems like the crux of the problem and I suspect this is more of a problem with popular frameworks like Next.js, rather than a general skills issue.

A human isn’t going to read the docs when implementing something they think they already know. Why would an agent?

We go to the docs when we’re stuck or something doesn’t work how we expect, but rarely before.

The question is, should LLMs be trained to behave differently? Maybe?

One way I work around this is instructing agents to always provide external references (eg links to documentation) when crafting implementation plans. That sort of forces to agent to go find supporting docs.

These days there's 200-350 new games released on steam every week. There's plenty of excellent narrative driven games if that's what you're after, mostly from indie developers.

If you're looking for deep narrative from AAA games, then the best you'll find are games like Cyberpunk 2077 - which have some decent writing in between all the action. But if you want something that'll really scratch a strong narrative itch, you gotta go deep on indies. That's where all the experimentation is happening.

You might also just be getting more genre savvy with age. When you're a kid, story beats are mind blowing. But most narratives - especially in games - tack pretty close to classic hero arcs. Once you've seen 100 of them you can often predict out how a story will end from the end of the first act. In other words, it might not be that games have gotten worse. It might just be that you've gotten better at understanding story and as such your standards have gone up.

To everything you can find exceptions, no one's arguing what you're claiming. And you have to read between the lines here, a board doesn't have to remove a CEO for a decision, what I'm trying to point out is the CEO knows their job, and the board knows their job. Just like there's things you know if you do you won't get a good pay raise or bonus (or gasp, get fired), the CEO knows how to avoid that in the long term. The board also knows what they must do over the long term to keep their nice board seat. No one has to get sued to get the message.

Different cities. Different transport situations. I'm not convinced I would take commuter rail in and out of where I live to Boston even if it ran more frequently. Chicken and egg and all that but it's empty in the evening as it is.

Even the reverse commute in the evening is annoying but then it's quite straightforward to go home. There are usually reasonable parking options. Personally, not sure I'd use it outside of rush-hour in and back.

I did a detailed review of a few Canadian VPS providers last year.

Last year, I moved from DigitalOcean to FullHost (their Vancouver datacentre) for hosting a small SaaS and a bunch of personal projects. It's cheaper and FAR better performance.

If you're struggling with keeping your attention, you ought to try making a list of games you never finished (or never played) and commit yourself to playing through them in order. I have been doing that with NES games and really enjoying it. I alternate between RPGs/adventures and action games, to mix things up a bit.

Recently, I have played through Faxanadu, Dragon Warrior, Blaster Master, and am now working through Fire Emblem (translated from Japanese).

Yea some cloud providers are notorious for it.

Netcup does oversubscribe/overshare but not sooo much. I have a server there and I don't really observe too much but although I haven't really gotten ways to detect that stealing factor but there are definitely scripts to detect it, maybe I will run it some day but oh well the laziness.

The most overshared vps provider I know is contabo. Literally search anything on reddit,lowendbox, literally anywhere where there are people and they mention about how ~20-30% figure top of my head could be oversubscribed

I am not exactly sure but my point is that when I first saw them, I found them the cheapest option (with their contabo auctions for something at really scale like 96 gb ram or something) but they are literally out of my book as well even as a frugal guy just because of how unstable they are or how much consistent I have seen people struggle about contabo. It's simply unrecommended imho. Netcup's 10x more pleasant from what I see other people's reaction to. People do mention some stealing factor on netcup but overall its really good and that sort of aligns with my experience with them too ig/

It's the same thing as saying "It's not my fault, it's a bug in the spreadsheet". The human is ultimately responsible. Heck, it's the same thing as someone saying "the computer made a mistake". Computers don't make mistakes. People do. The hallucination defense is not a defense at all and this is a non-issue. There's nothing to talk about here.

And if a professional wants to delegate their job to non-deterministic software they're not professionals at all. This overreliance on LLMs is going to have long-term consequences for society.

Hi HN,
We’re building at Cleanster, and we just launched a white-label API that lets cleaning companies, building management platforms, and short-term rental hosts automate cleaning services directly from their own software.
The idea is simple:
• Plug our API into your system
• Offer on-demand or scheduled cleaning to your customers
• We handle fulfillment through a network of 150,000+ professional cleaners

The API covers booking, pricing, scheduling, cleaner assignment, and status updates, so teams don’t need to build or manage an ops layer.

We’re seeing interest from property management software, STR platforms, and vertical SaaS tools that want to add cleaning as a built-in feature instead of a manual workflow.

Happy to answer questions about the API design, scaling marketplace logistics, or what we’ve learned building this so far.

Will the people of the US invest in an energy transition?

They thought they were investing in energy independence: we've never pumped more oil or exported more oil than ever before!

But we don't actually have energy independence:

Texas doesn't refine the crude pumped out of Texas.

The US cannot export oil without importing.

The US still must import foreign crude and other oil to blend into gasoline.

If the US had invested the amount invested in foreign wars (which subsidize the price of gasoline) in clean energy and storage, we would be significantly further along on our next energy transition.

But we can't seem to stop ourselves from getting taken by freeloading oil lobbyists that don't pay their debt-financed war bills.

People fought the Keystone XL pipeline here in the US for years before Trump weakly capitulated to Canadian oil.

This looks great. I was hoping it would have been a good OrcaSlicer replacement for my FDM printer, but unfortunately it didn't generate any top surfaces (except for the topmost one) for a model I imported in. I didn't know if it was the printer profile (Creality.Ender3) or something else, but it seems I'm still using OrcaSlicer for the time being.

This is the problem we're working on.

When orchestrators spawn sub-agents spawn tools, there's no artifact showing how authority flowed through the chain.

Warrants are a primitive for this: signed authorization that attenuates at each hop. Each delegation is signed, scope can only narrow, and the full chain is verifiable at the end. Doesn't matter how many layers deep.

>AI is just better because no one can actually explain why the thing does what it does. Perfect management scapegoat without strict liability being made explicit in law.

AI is worse in that regard, because, although you can't explain why it does so, you can point a finger at it, say "we told you so" and provide the receipts of repeated warnings that the thing has a tendency of doing the things.

This was clearly written by a pedant of the worst kind, boasting of how great he and his friends are at "mocking people who denigrate the passive without being able to identify it".

It is understood by basically everybody that there are two different things meant by passive vs. active: on one hand, the technical grammatical distinction, and on the other, the broader spirit of the phrase. Edge cases are very easy to construct: passive clauses where the agency is well-identified, and active clauses where responsibility is totally diffuse. This technical clarification is needed by nobody, because a rule-of-thumb like "avoid passive voice" is meant to be used holistically, not literally.

There often are hotels, but it gets booked fast when weather causes delays. When I got stranded in Dallas in 2019, the Ramada made it excessively clear they were booked. But there's also tons of hotels around airports, you just have to get through security, and they don't do hourly billing like you might want if you weren't sure your replacement flight is also delayed.

They all bear some of the blame.

Software engineers are hired to be the expert in their field. If you don't learn your craft, managers aren't going to do it for you.

Ideally new hires would be mentored by senior engineers who understand performance, and who can teach new hires how to write (and ship) good, performant software. But unfortunately that doesn't happen anywhere near as often as it should.

You may have done so inadvertently. With the transition to doc-in-the-box urgent care with NPs with inconsistent training and massive caseloads... your provider is often using ChatGPT.

I caught one when i ask ChatGPT something, and then went to urgent case. I told my story, they left, came back and essentially read back exactly what ChatGPT told me.

Having everything in one unit is a recipe for a single point of failure disaster. Because it's Samsung, don't expect any of the parts to be interchangeable.

I agree. The dog smashed the window, hot–wired the ignition, released the parking brake, shifted to drive, and turned the wheel towards the opposite side of the road where a mother was pushing a stroller, killing the baby. I know, crazy right, but I swear I'm not lying, the neighbor caught it on camera.

Who's liable?

Tesla's greatest strength is/was that they did almost everything inhouse. The reason all the other manufacturers struggle to do basic things like dog mode is because they are almost all relying on the supply chain for everything. No infotainment/HVAC supplier has a dog mode so it doesn't exist.

The obvious downside to that is that when Tesla cuts back on R&D, it becomes painfully obvious to the car owners. I'm not expecting anything like dog mode to show up ever again.

No I found it readable though I can understand why they might be confused a little bit too but its nothing to worry about in my opinion.

Honestly regarding your anecdote and the gourmet syndrome the title itself, I don't really have nothing to add except I guess just note that human mind truly just works in remarkable ways.

But each day science uncovers more and more secrets about our brains. Maybe one day the gourmat syndrome or (your anecdote [if its a syndrome? or anything more observed or who knows, I am not sure as I don't have much medical knowledge being honest] might be explained in future too by future science advancements and scientists)

It's crazy how far we have come in medical science and (also not) [but I don't mean it in a bad way] at the same time.

Yeah, sometimes it seems there is a certain kind of devs who don't just like code for the sake of it, but have an active hostility against GUI tools and visualization in general, for whatever reasons.

I get the appeal of "change a number and regenerate everything" as well as "you can store everything in git" - but there is no reason why a decent visual CAD program couldn't do both of them just as well.

In contrast, the ability to actually see a part in front of me and not having to mentally visualize it the whole time seems substantial to me.

Not aging does not mean infinite life.
Not only can you end it whenever you want, but you can still have accidents or win a Darwin Award.

Also, longer lifespans open up space exploration and so much more.
Anyway, I don't know if I want infinite life, but I definitely want us to beat aging, it sucks from every possible point.
