Because in this case the value can change overnight, and Valve doesn't otherwise have control over the market (value) of the items.

Expensive clothes aren't much more expensive to produce than cheaper ones, but it is known that brands like Louis Vuitton will destroy old stock rather than put it on sale. Some products are intrinsically valuable though, because production can't scale as well - some cars (although a brand can do a new design and mass produce it), watches, semiconductor manufacturing, etc are constrained due to their complexity.

Damn this takes a long while to wrap your head around.

I think it would be better if there was a tutorial mode that doesn't show confusing screenshots but lets you play an easy preset of metaphors first, so you can learn how the game works.

To me the tutorial didn't explain anything, honestly, that's why I was so confused when I tried it afterwards and had to click Reveal anyways.

Now I can't play anymore but I think I understood the game mechanic, and am now disappointedly not able to play again until tomorrow.

Yes but as I said yesterday on another post, "Yngwie Malmsteen Code".

You could write it clearly by saying foo[1] instead of *(foo+1) which is what they ended up doing, but hey, pointer arithmetic looks complicated and clever, so let's show off with a WEEDLYWEEDLYWEEDLY guitar solo bit of code.
Tell HN: OpenAI now requires ID verification and won't refund API credits
by retube | 2025-10-25 09:02:14+00:00
Just frustrated here: I credited my OpenAI API account with credits, and then it turns out I have to go through some verification process to actually use the API, which involves disclosing personal data to some third-party vendor, which I am not prepared to do. So I asked for a refund and am told that that refunds are against their policy.

So I'll be cancelling my chatgpt plus sub, disputing the card payment, and moving to deepseek.

Edit: Deepseek seems to be a lot cheaper than OpenAI

Edit 2: seems verification is only needed for gpt-5, gpt-4o seems to work without it

If you buy your vacuum in china it’s about half price, but it’s geolocked to the mainland. There’s some dodgy looking Cyrillic project that unlocks it via VPN or something like it.

IMO not worth it now that Dreame started to repackaging their bots into cheaper brand Mova for roughly half price too.

yeah, i really think it accomplishes a lot.

at a minimum, it makes it clear to others that they are not alone in thinking this regime is beyond the pale.

people who are able to take other actions like engaging via the judicial system, or peacefully refusing to continue working, are also encouraged by seeing peaceful masses of people agreeing with them.

it actually harms the cause to be dismissive of people who can contribute by simply making their peaceful objection visible.

You'd probably end up with tighter and tighter tolerances such as they mention with the triakis tetrahedron.

The challenge is that it gets computationally intensive the more sides that you add if you don't have shortcuts like ruling out entire blocks of orientations in their parameter space (they figured out that if one shadow, projection, protrudes significantly, then you'd need a large rotation to get that protrusion into the other shadow, thus removing all of those rotational angles and reducing the number of orientations needed to check). More sides and more symmetry make it much harder to test a candidate, but you have an interesting idea.

I've had exactly the same situation, ~2M MAU service with REDIS as the only persistence system, all data being JSON serialized Pydantic models. The storage overhead was just terrible and cost real money.

This would have been a super nice to have back then.

I wonder though how much sense it would make to get something like this mainlined into upstream Pydantic? as having this downstream would give many continuity and dependency lock concerns. And having it as part of the main library would significantly drive adoption rate.

i use luau a lot as part as my Roblox development work, it's pretty fast for its main use case.

there are people a lot more knowledgeable about this topic so i won't pretend to know this is possible, but could a versioning flag similar to the !native flag be added? it would allow both for backwards compatibility and better optimizations, although i know it might add complexity where it's not needed

The reason it isn't, is because it's automatic. Your brain keeps you breathing as much as it can (if you hold your breath until you pass out, your brain will start breathing again for you). Breathing isn't reward driven. It doesn't engage the dopamine system the same way, eg cocaine does. You don't become tolerant to breathing the same way you do, eg cocaine. Lastly, for something to qualify for Substance Use Disorder (SUD), they need to keep doing it, despite social and health ramifications of continued use in the face of developing a tolerance for it. Other than some edgelord shit, no one's gonna give you shit for continuing to breath.

> the gold thing seemed like a good, cheap way to get on Trump's good side

Which, whilst morally repugnant, does make business sense - if Apple got hit by tariffs or other penalties, you can be sure the Carl Icahn style leeches would be popping out of the woodwork complaining that Tim Cook was ruining Apple / the share price / etc. and trying to orchestrate shareholder and/or board revolts.

(And Good Lord, imagine the threads on here if Apple's value dropped just because Tim Cook didn't give a hideous piece of tat to Trump.)

Gyroscopes are used in spacecraft / satellites in the same manner they are in aircraft, to measure changes in orientation.

Reaction wheels are used to make adjustments to orientation. See https://en.wikipedia.org/wiki/Reaction_wheel

Thrusters of all sorts can also be used, generally to maintain altitude in satellites, and more generally to provide thrust for space probes.

The devil's advocate would lift a few points. The OP equates disagreement with conflict and sees the main cost as being loss of status and "hurting team vibe". They seem to make a point that their own main contribution is bringing stability (good vibes?) to the team.

It could be the story of a weak or unaware engineer/employee that has been promoted to a level they thought implied some sort of impunity. Because being reviewed or questioned weakens the public perception of them, they experience it as unfair and toxic. Using the word "trivial" to characterise critique directed towards them could be emotionally rather than technically motivated.

They already did:

> Researchers have noted instances where devices known to be active had their shutdown.log cleared, alongside other IOCs for Pegasus infections. This led to the conclusion that a cleared shutdown.log could serve as a good heuristic for identifying suspicious devices.

Which is why the article is pointing out that a cleared `shutdown.log` is no longer an indicator of Pegasus infections (because it now happens every boot.)

I guess at scale every minor fix is a spacebar heater for someone else. I assume Apple is probably going to bring this back to pacify the iVerify people but long term they are going to keep making these changes and mercenary spyware is going to learn how to hide itself better. I really think it’s time to start thinking about strategies that go beyond forensic artifacts…

The way the author describes it (in contradicting terms; see the point where he claims if you're a Principal IC, you were promoted because you already acted like one, making the ~30 items of advice redundant) it's the most stressful position ever.

Be critical, don't be in the critical path, be laid back in an advisory role but be hands-on or you're setting yourself up for failure, work on stuff you enjoy but be ready to justify why it needs a Principal or you're "working on the wrong thing", sponsor, consult, explain to leadership, mentor, code, be present, do not be too present, "feel the pulse", don't attend too many meetings, don't attend too few, gently nudge, don't speak all the time, be careful about staying quiet, etc etc.

Seems like hell. And presumably, you'll get fired if things turn out badly with a project.

Thanks, but no thanks.

I've tried to make AI work but a lot of times the overall productivity gains I do get are so negligible that I wouldn't say it's been transformative for me. I think the fact that so many of us here on HN have such different experiences with AI goes to show that it is indeed not as transformative as we think it is (for the field at least). I'm not trying to invalidate your experience.

> If people dont know what to do with themselves its kinda their own issue.

That "kinda" is important. I didn't have the freedom to just do what I wanted to when I was a young teen. 14-year old me couldn't just take a walk. I'm in my late 40s now - my mother was particularly strict for the time period.

People have children. Some folks really are stuck at home, taking care of someone, with a life peppered with boredom. You know, like parents. Screens have a way of decorating those bits of time and lessening the monotony of it all.

Not to mention the effects of being poor - I'm not even talking outright poverty here. Just a point that you simply have to budget somewhat carefully and don't have a lot of extra money. One of the great things about the internet is the entertainment built right in. You pay for the communication access society and businesses expect from you, you get entertainment as well.

Societal expectations might also keep you in. If you need an app to make sure that your child isn't left out, it might mean that you don't have the same options to simply quit something without harming innocent folks along the way.

Other folks have touched on the addiction bit, so no need to repeat here.

Right, and recommendations for old car repair videos that you watch a few of per week is reasonable.

The argument I’m making is that it’s not beyond the pale for YouTube to detect “hey it’s been over an hour of ai bullshit / political rage bait / thirst traps / whatever, the algorithm is going to intentionally steer you in a different direction for the next little bit.”

smoking, alcoholism and obesity are fiscal positives, not negatives.

smokers pay obscene amount of money in cigarette tax for decades only to die in their 50's or 60's instead of collecting the benefits of having also contributed into social security all their lives. most of them die suddenly from a heart attack or after a short illness.

Actually with CS stuff there's scarcity too, but since it's digital it's easy to change. Same with designer bags (nothing stopping them from churning out more, but they choose not to do that). Not so with vintage items though, since they're no longer made.

But a lot of Stuff is made with future vintage in mind, e.g. every Ferrari or other high end sports car will only appreciate in value.

I enjoyed the title more that I want to admit TBH :)

In every country in Europe people are pissed with their government and hate the police but when its a "Euro" thing it feels much better.

The online narrative may make you think that "Europe" is a dirty word(chat control, cookie banner, regulations, fines etc), but its actually much more pure than any local politics and much much less divisive. The "Euro cops" phrase gives me the feeling of bunch of police officers that are not particularly fun at parties but are definitely not corrupt.

Running the docker variant, it is trivially easy, you just bump the tag version.

They are and they aren't. They're both a form of escapism, for the user to deny reality while in an altered state of consciousness. Users do it to their detriment, despite social and health consequences. Thus, some of the techniques used to help people with substance use disorder (SUD) are also applicable to screen addiction. fwiw, gambling addiction is another different but same addiction with similar treatment plans. No, gambler's aren't shooting up heroin the the bathroom, nor are screen addicts, but at some level they are comparable. The first thing you reach for in the morning and the last thing you think about before bed.

It takes about 10 minutes to take a single 4x5 photo, and you have to carry around a tripod and a fairly bulky camera to do it. So the time and effort invested in taking the photo is similar to the time and effort required to develop and scan the negative.

In contrast, a 35mm camera is very convenient and you can expose an entire 30 frame roll of film in a few minutes. But getting high quality scans of all those frames requires either a lot of time or a lot of money. (Consumer flatbeds give poor results for 35mm, so your best bet is putting the negative on a light table and using a digital camera and macro lens. But that’s a physically fiddly process, the ‘scan’ needs manual spotting for dust, and if you’re shooting color negatives you also have to do some work to get the colors right.)

Back in the day, most users of 35mm cameras were satisfied with waiting a week to get a set of prints with absolutely no creative control over the printing process, but that’s not what most people want now.

I have a Star Micronics receipt printer and have a similar setup, and when people in my community used it, it was fun.

And the issue is that, it's only fun as long as you have people using it...

I did write a StarPRNT protocol library for it, but in hindsight, I probably should have used ESC/POS instead.

Counterpoint: asking GPT can provide useful calibration not to facts but to median mental models

As a bonus you can prime the respondent's persona.

Nobody is going to lock in the choice of where they're going to spend 12+ hours a day every day for years without reviewing the available information themself. Even if my partner did the selection themself, I would still look through their results. So the question is: "would I trust an AI to sort a list of properties?" The answer is sure. Platforms have stuff like price and location already. What they can't do is more fuzzy stuff like "has a lot of natural light". So there is some value there I think. That said I don't think there's a product. It seems like just a feature for an MLS system.

The world doesn't operate with code as law. If somebody steals all the bitcoins in the world then they'll just fork it [1].

A significant amount of bitcoins are held by known entities (exchanges) so it's pretty trivial for institutions to keep their coins after a fork. Those of you self-hosting might have some losses.

It's common for wake-on-LAN clients to send UDP packets to port 9 to make sure they get discarded. This is particularly useful if using a multicast or broadcast destination, which is often the case because the ARP entry will have been discarded by the time you need to send the packet.

The hardware that looks for the magic packet ignores the framing.

I certainly wouldn't run a TCP discard service, but making sure that UDP packets to port 9 do not result in any ICMP port unreachable response, or any other response, is a good practice.

I moved away from using Tailwind CSS, but still use their "preflight.css" [1]. It doesn't really care about backwards compatibility (IE stuff), but does a great job at unstyling everything so you have a clean cross-browser base to work with (button will look like text until you add your styling).

Honest question, how well does it go for for email ?

I did that pretty seriously for a while, and in my case I feel it led to nothing specific. I'd get spam from weird places and shut the address, but that would actually amount to an extremely small amount of the total spam I was getting.

Also my ISP or the phone company was selling away my email and there was no way I'd just block them, nor would they give a shit about my bitching to their customer support.
by alexgieg | 2025-10-25 09:16:40+00:00
In a word, yes.

Longer answer:

Any content the moral panic at the time is panicking about will require age verification. Only things moral panickers believe is child-appropriate will be accessible without it.

This includes forums. If people can interact with each other, one of them miiiiiight be a child (no matter the forum's topic), and the other miiiiight be a pedophile. Therefore, ALL forums will be obliged by law to age-verify their users for them to be able to even read user submissions, this one here being a prime candidate.

And, note, this is a bipartisan effort in the US. All proposed bills are supported by Democrats and Republicans. Google is merely doing it on their own before the relevant laws are approved, so as to be ready when everyone starts struggling to become compliant or have their sites shutdown.

> This is an incredibly ignorant take on addiction. It's never a choice - by definition.

It isn't that clear cut either way IME.

I had a big drinking problem. I was the one that choose to start drinking. I was the one chose to stop drinking. Nobody forced me to go to the bar or the off-licence.

I accept for other people it isn't that simple.

> Hey, do you want to chat about how when I tried to quit nicotine, I went through 2 weeks of physical and mental hell, how exhausted I felt not being able to sleep more than an hour without waking up, still feeling exhausted, with mental fog so severe that made quitting feel impossible?

I had similar issues when I quit drink. Sleep was irregular, I went hot and cold for the first month. I had this like weird wave feeling go through me one night (it the only way I can describe it). I think that took like a month or two.

Are you an individual contributor if the vast majority of your work isn’t individual contribution? And you’re not a “working-level” IC? God I hate all this big corporate hierarchy terminology. Along with all the pontification about what a “staff” or “principal” or “senior” really is, as if the terms have (or can have!) a stable meaning that we definitely agree upon enough for this all to make sense.

What a terrible article. The author throws completely different types of problems into one pot, regardless of whether they have real User-Impact, cause Potential Security problems or Data loss or are just architectural decision with no user-impact at all. And then continues to apply the same logic and argument to all of them - that the users are wrong and should just shut up.

Take this one for example https://codeberg.org/stagex/stagex/src/branch/main/src/compa...

It took some iteration and hands on testing to get that right across multiple operating systems. Also to pass shellcheck, etc.

Even if an LLM -could- do that sort of thing as well as my team and I can, we would lose a lot of the arcane knowledge required to debug things, and spot sneaky bugs, and do code review, if we did not always do this stuff by hand.

It is kind of like how writing things down helps commit them to memory. Typing to a lesser extent does the same.

Regardless those scripts are like <1% of the repo and took a few hours to write by hand. The rest of the repo requires extensive knowledge of linux internals, compiler internals, full source bootstrapping, brand new features in Docker and the OCI specs, etc.

Absolutely 0 chance an LLM could have helped with bootstrapping a primitive c toolchain from 180 bytes of x86 machine code like this: https://codeberg.org/stagex/stagex/src/branch/main/packages/...

That took a lot of reasoning from humans to get right, in spite of the actual code being just a bunch of shell commands.

There are just no significant shortcuts for that stuff, and again if there were, taking them is likely to rob me of building enough cache in my brain to solve the edge cases.

Also yes, I only use FOSS tools with deterministic behavior I can modify, improve, and rely on to be there year after year, and thus any time spent mastering them is never wasted.

The water temperature which you deliver to radiators are not defined by capacity of the heatpump, but how hot the radiators can be for safety/comfort reasons. If the radiators are too hot people could burn by touching them or stuff like platsic chairs would melt. Also the piping in the walls and floors cannot support too hot temperatures.

The temp for water used in radiators 60-70C is easily achievable by an air-top-water heat pump. It does not depend on the energy source, gas/oil/electricity.

> now fruits are also being engineered to be sweeter

Yes. But it's not by injecting sugar into fruits like many people think.

Farmers including the one next to my rural alt house:

- Take consultancy of agritech and selectively breed variants that are sweeter [0]

- Optimize min(fruits/tree-or-vine) to concentrate sugars in remaining fruits. [1]

- Ethylene-based post-pluck ripening to convert some starch to sugars and make it sweeter. [2]

- and more. Richer the farmer, the more sophisticated the techniques.

If you want truly fresh natural fruits, buy from a poor farmer directly and pay for logistics yourself. They have to be poor because well, they have to sell at market rate. Tragedy of the commons and all that. And logistics chains depend on fruits being fairly resilient. The logistics loss for natural fruits is 30-50% depending on the fruit. So yeah you need to pay 3x as well.

[1] this technique leads to lesser minerals, polyphenols, vit c etc in fruits. "Crowding out".

[2] this technique leads to less fiber formation since there's no time for polysacs to form. Major reason for fiber deficiency today according to agtech person I know is that people are eating fruits the same way their grandparents did, but whoops, you don't get enough anymore.

[0] They are bred to naturally do the above two things. Mostly, they are bred to autocatalyctically generate ethylene earlier.

If your country is in the business of exporting fruits, then the farmer has to compete with the whole world, and the tragedy of the commons mentioned above goes global. So every effect mentioned above multiplies 2-3x. Because it has to be even more logistics friendly, supply has to be really uniform due to expensive GTM, etc,.
