Do you have to prove that your 3D printer cannot print a 3D printer which can print a gun?

This reminds me of Ken Thompson’s speech on trusting trust. The recursive/meta nature of it all has helped me explain to those unfamiliar that this is such a waste of time. Education is where it’s at, but I’m preaching to the choir here on HN.


Not OP but yeah that's the one!

when offspring are forbidden, only outlaws will have in-laws

only when they start printing ICs

Trying to restrict the non-printed ICs you'd connect to your 3D printed parts would be even dumber. There's a zillion things that can slam out bits and control a stepper motor.

you can build a 3d printer out of general-purpose electronic bits, anything they tried to ban would send ripples into countless other industries that are completely unrelated to each other or 3d printing.

By "general-purpose" I mean that there's no components that are 3d-printer specific; motor controllers and microcontrollers and voltage regulators and all the various jellybean parts. And even if there were any, they could easily be replaced with general-purpose components.


Well, you can print out of conductive materials.

Like the printers that won't do prints of money that's money-size

Apparently Haiku is a very anxious model.

>The anxiety creeps in: What if they have removal? Should I really commit this early?

>However, anxiety kicks in: What if they have instant-speed removal or a combat trick?

It's also interesting that it doesn't seem to be able to understand why things are happening. It attacks with Gran-Gran (attacking taps the creature), which says, "Whenever Gran-Gran becomes tapped, draw a card, then discard a card." Its next thought is:

>Interesting — there's an "Ability" on the stack asking me to select a card to discard. This must be from one of the opponent's cards. Looking at their graveyard, they played Spider-Sense and Abandon Attachments. The Ability might be from something else or a triggered ability.


The anxiety is coming from the "worrier" personality. Players are combination of a model version + a small additional "personality" prompt - in this case (https://mage-bench.com/games/game_20260217_075450_g8/), "Worrier". That's why the player name is "Haiku Worrier". The personality is _supposed_ to just impact what it says in chat (not its internal reasoning), but I haven't been able to make small models consistently understand that distinction so far.

The Gran-Gran thing looks more like a bug in my harness code than a fundamental shortcoming of the LLM. Abilities-on-the-stack are at the top of my "things where the harness seems pretty janky and I need to investigate" list. Opus would probably be able to figure it out, though.


Ha! I misread it as "Haiku Warrior" and so didn't make the connection. That makes a lot more sense!

Well, typically for higher progressive taxes. Tariffs are typically a regressive tax.

>The randomly selected applicants

Why would you want to randomly select here?


That's the best way to do it. Otherwise all the money will go to the rich brat children of politicians/etc who are socially connected to whoever they put on the selection committees.

I'm not sure that's true. What kind of rich brat will go through the trouble of all that for a couple hundred euros a month?

Random isn't a bad way of doing it in any case though.


Rich parents are masters of helping their children exploit the system in as many of the thousands of ways that exist. A few hundred here, another hundred there, maybe some one-off thousands here.

In most of the world, rich people are rich because they are good at exploiting government funds. It's a lifestyle.


I agree that it's a problem. But how do you prevent it from been overflowed by people like me that can't draw a circle with the bottom of a bottle?

Dunno tbqh. Maybe the media will police it by shaming people who abuse it.

Mostly because the kind of people who run and advocate for programs like this are actively hostile to the idea of merit. Prioritizing talented people would be antithetical to them.

Prioritizing merit would be fine if there was some way to measure merit empirically, and if that measure couldn't be gamed by anybody with money and/or connections. But this is for artists, so...

I bet you also think government shouldn't be picking winners and losers.

And thinks that s/he's a winner and the stuff s/he enjoys is made by winners, and the stuff s/he doesn't like is made by losers. Merit, universal, objective = ME; Worthless, narcissistic, special interest = YOU.

Why wouldn't you? How do you define merit to artists? Many of the greatest artists of all time lived their entire lives in poverty and desperation.

To not have selection bias so you can measure the effects

Random selection is possibly the fairest way to select almost anything, depending on your definition of fair.

I am in the "did not read a single book" bucket, and have been for many years. I just don't like reading books, and never have.


>An advertising-based business model would introduce incentives that could work against this principle.

I agree with this - I'm not so much worried that ChatGPT is going to silently insert advertising copy into model answers. I'm worried that advertising alongside answers creates bad incentives that then drive future model development. We saw Google Search go down this path.


>By contrast, intrinsic mortality stems from processes originating within the body, including genetic mutations, age-related diseases, and the decline of physiological function with age

So we put genetic diseases in the bucket of intrinsic mortality and then found that intrinsic mortality has a heritable component?


Yeah this paper came across to me basically as "if you ignore environmental causes of death, the heritability of death goes up"... which seems kind of circular.


Not necessarily. It could be the case that randomness plays a huge part in non-environmental caused deaths, and if that were the case we would see very little heritability.


But randomness comes from the environment, no?


No, you randomly get cancer since cancerous mutations happens randomly. Environment can just affect chance of getting cancer, it doesn't give you cancer directly and there is no way to completely avoid cancer risk.

For example even if you live the best life possible you will still have an inherent cancer risk based on your genes and that affects the random chance of you getting cancer, it isn't a clock that says exactly when cancer will happen.


Technically, sure, but that doesn’t mean it is related to anything observable about your environment.


I really like everything Uri Alon (last author) publishes, but these types of studies have a history of inflating genetic contributions to phenotypes. Decoupling genetics from environment is not easy as they are both highly correlated.

In fact, the article discussion states: "Limitations of this study include reliance on assumptions of the twin design, such as the equal environment assumption". My take on this is that the main result of the article is probably true, but the 50% figure is likely to be inflated.


I hit the jackpot with the ultrasound technician who spoke passionately about what she believed about lifestyle risk for cardiovascular conditions and she believed quite strongly that heart disease runs in families more because lifestyle runs in families than because of genetics. She's not at the top of the medical totem pole but I can say she inspired me to take responsibility for my health than the specialist who I talked to about the results.


Actually the opposite is true.

If the environment was significantly more varied in health impact between twin comparisons than expected, then the correlations they found under estimate the genetic component.

Noise weakens correlation. Removing noise strengthens correlations.

Some randomness is part of the signal being studied, and some is undesired measurement noise to be controlled for. And it is only the latter that is beneficial to be carefully removed or otherwise controlled for.


There's no prior reason to expect the cited conditions to have any specific relation to genetics. Any of them could easily be caused or accelerated by environmental conditions.

And, in fact, it looks like they half-of-are.


I thought the implication was lifestyle isn't as important as we previously believed.


On average! Start drinking a lot and find out.


Yeah, it’s important to note that heritability is a statistic about today’s population, not a deep natural parameter that tells you about causality. Heritability of smoking went up when smoking became less socially approved, for example.


I am somewhat surprised that the constitution includes points to the effect of "don't do stuff that would embarrass Anthropic". That seems like a deviation from Anthropic's views about what constitutes model alignment and safety. Anthropic's research has shown that this sort of training leaks across contexts (e.g. a model trained to write bugs in code will also adopt an "evil" persona elsewhere). I would have expected Anthropic to go out of its way to avoid inducing the model to scheme about PR appearances when formulating its answers.


I think the actual problem here is that Opus 4.5 is actually pretty smart, and it is perfectly capable of explaining how PR disasters work and why that might be bad for Anthropic and Claude.

So Anthropic is describing a true fact about the situation, a fact that Claude could also figure out on its own.

So I read these sections as Anthropic basically being honest with Claude: "You know and we know that we can't ignore these things. But we want to model good behavior ourselves, and so we will tell you the truth: PR actually matters."

If Anthropic instead engaged in clear hypocrisy with Claude, would the model learn that it should lie about its motives?

As long as PR is a real thing in the world, I figure it's worth admitting it.


A (charitable) interpretation of this is that the model understands "stuff that would embarrass Anthropic" to just be code for "bad/unhelpful/offensive behavior".

e.g. guiding against behavior to "write highly discriminatory jokes or playact as a controversial figure in a way that could be hurtful and lead to public embarrassment for Anthropic"


In this sentence, Anthropic makes clear that "be hurtful" and "lead to public embarrassment" are separate and distinct. Otherwise it would not be necessary to specify both. I don't think this is the signal they should be sending the model.


This was one of my favorite parts. The honesty provides evidence that Anthropic is actually living up to their name here.


>ChatGPT’s responses will not be influenced by ads

I don't see why I should believe this.


Do you believe google search results are influenced by ads?


Yeah, both directly and indirectly. Over time, "sponsored links" became more and more visually indistinguishable form organic results, and advertising incentives drove changes to the search algorithm.


Considering that I have reported a Google ad that I deem political and Google does not, that I'm going to appeal because as a eu citizen I can do so, that they'll most likely refuse the appeal and I'm ready to bring this to the relevant Italian authority, yes

A few days ago I read a newspaper article about Israel's government using ads to spread its propaganda. In eu, you have to follow some rules if you want to do so. These rules are not followed. Combined with the fact that ads might not be distinguished easily by average users, I feel that Google search results can be influenced by ads


>By default, the main thing to know is that Claude can take potentially destructive actions (such as deleting local files) if it’s instructed to.

What do the words "if it's instructed to" mean here? It seems like Claude can in fact delete files whenever it wants regardless of instruction.

For example, in the video demonstration, they ask "Please help me organize my desktop", and Claude decides to delete files.


I believe the idea is that it “files away” the files into folders.
