Sure but the exploit here isn’t prompt injection, it is an edge case in their billing that isn’t attributing agent calls correctly.
That's fair - I suppose the agent is making a call with a model parameter that isn't being attributed, as you say.

Every time I see something about trying to control an LLM by sending instructions to the LLM, I wonder: have we really learned nothing of the pitfalls of in-band signaling since the days of phreaking?
> “No person shall circumvent a technological measure that effectively controls access to a work protected under this title.”
This wording always bothers me. If a person were to circumvent a technological measure that tries to control such access, then the circumvention itself proves that this measure was not effective at doing what it is supposed to be doing. Therefore the person is not circumventing something that _effectively_ controls anything. They just showed that it is ineffective, and therefore the law does not apply to them.
Of course, no one who actually has to interpret these laws shares my opinion.
The meaning of effect is not what you think it is. In this case it simply means “to bring into being”, or “have the intent to”.

That is my understanding from the outside as well. The core question here should, I think, be whether the adoption and spread of clearer semantics via Rust is worth the potential for confusion and misunderstandings at the boundaries between C and Rust. From the article it appears that this specific instance actually resulted in identifying issues in the usage of the C api's here that are geting scrutiny and fixes as a result. That would indicate the introduction of Rust is causing the trend line to go in the correct direction in at least this instance.
That's been largely my experience of RIIR over years of work in numerous contexts: attempting to encode invariants in the type system results in identifying semantic issues. over and over.
edit to add: and I'm not talking about compilation failures so much as design problems. when the meaning of a value is overloaded, or when there's a "you must do Y after X and never before" and then you can't write equivalent code in all cases, and so on. "but what does this mean?" becomes the question to answer.

Not sure if it introduces a tiered experience or not. But reading the article it appears that the Rust devs advocated for an api that is clearer in it's semantics with the tradeoff that now understanding how it interacts with C code requires understanding two APIs. How this shakes out in practice remains to be seen.
Advocating for an API with clearer semantics has, afaict, been most of the actual work of integrating Rust into the kernel.

There is no need to repeat the word social so often. We can argue infinitely at any level of substraction. In humans there are two sexes. In some other species there are eight. Start from there and build your way up.

You claim to be a doctor (again, of what?). Have you even heard the word intersex before?

Wow. I've read a lot of hacker news this past decade, but I've never seen this articulated so well before. You really lifted the veil for me here. I see this everywhere, people thinking the work is the point, but I haven't been able to crystallize my thoughts about it like you did just now.
Marx had a lot of good ideas, though you wouldn't know it by listening to capitalist-controlled institutions.

an interesting contrast that i think about a lot:
- in rural america, there are dollar stores everywhere that overcharge for small items. people treat them as a necessary evil and begrudgingly shop there.
- in nyc, there are corner bodegas everywhere that overcharge for small items. they are generally seen as beloved neighborhood institutions.
so... what's the difference? corporate owned vs family owned? length of time in community? presence of cute cat at the register?
Bodegas charge you a little bit more because a real human owner accepts the risk of serving a small community in exchange for being part of that community, and you pay that extra in order to make their existence possible.
Dollar Generals charge you a little bit more because a huge chain has driven out all the competition and you have no choice. The people who work there do not benefit from the extra you pay, and the owners are not members of the community.

The Fuchsia guys use the trait system to enforce a global mutex locking order, which can statically prevent deadlocks due to two threads locking mutexes that they are both waiting for.
Doesn't help in this case, but it does suggest that we might be able to do better.
Any chance you could dig up a link to that code? I’m curious to learn more
At what point can we just return to 1990s wheel sizes, add the motor to the wheel, and have the same unsprung mass as we have with today's gigantic wheels?
As soon as the roads are as smooth as they were in the 90s. I have a pet theory that wheels have gotten huge partly in response to deteriorating roads - larger diameter means less leverage against the suspension when hitting defects. It’s the same reason dirt bikes have large front wheels.
