<p>Ah, hopscotch hash, I tried using it on my CSGO cheat literally 10 years ago, for the object reflection (retrospection) system based on compiler type ID and unique hashing scheme with function signature. I merely used it for hopefully getting a performance on the "dependency injection" side of things, until I realized it is actually a service locator pattern and performance won't improve due to this architecture anyway.<p>It was 3 years later when I was in college I learned advanced data structures and came into Cuckoo Hashing, then Robinhood hash, and the combination of both Cuckoo and Robinhood hash => Hopscotch hashing</p>

<p>Well all of those attacks are just supply chain attacks, and it is basically exploiting people's trust. With LLMs, the speed and velocity of pumping out malice raised are now significantly faster.<p>It is so sad that every goodwill eventually got enshittified as well.</p>

<p>That's by design of git, you can't forget that git is first developed for a bazaar model of information flow, especially with a big decentrailized project like the Linux Kernel, not the silo and isolated corporate NDA and closed model you described. Git prefers open information and discourages information closures and segregation of information by placing restrictions exactly like this.<p>Git enthusiast would often tell you to do this separately with a submodule, and set permission on the version control forge software level (which means Gitea/Github private RBAC access to certain repos for cloning), sure, but that is also painful as hell.<p>But my point is that all of this is exactly by design from Linus Torvalds's need for Linux Kernel to replace BitKeeper. Git simply isn't the tool for everything, it was developed for a software project with liberalism in mind, but corporate stuff is monoculture and prefers proprietary, shut-in model, and the eat your own dog food mindset, and no wonder it is so painful to deal with.</p>

<p>Yep. I also learned that too when watching Bauhinia team members' using this to solve a CTF challenge :p It is a multi-series CTF that you get shell from first a ROP chain to system, but you are effectively jailed from running anything but bash, so the only thing you can use is read and cat, and they used the cat /dev/tcp, then redirected it to a pseudo-tty, and read the content of the pseudo-tty in order to get the URL to the inner system. The flag, there it is.</p>

<p>Well, to be honest, from Anthropic's point of view this is really not a direct hit to their security barrier, but if we are using information theory and game theory here, this can be viewed as a classical, side chanel information leak, by asking an seemingly innocuous action, and then simply inverting the results to get the original information entropy, which the US Gov. and Pentagon are both certainly anal about.<p>The problem lies in the fact that the action of attack/defense exhitbits a rather special, structural reflexive duality of information, i.e. I(attack) = -I(defense), or in layman's term, what we call "two sides of the same coin": you need to know how to hit hard, so that you know where the optimistic hit points are, assuming the enemy is rational, so you can parry against the attack for defense, albeit also you need to know how to get the grip of the shield well.<p>And the worst thing is that if you're trying to correct it, it is basically tell the LLM not to give any kind of response, effectively assigning both I(attack) and I(defense) to 0, but this is also what kills the entire intent of using LLM to give you the magical answer.<p>To put it formally, you cannot prevent people from extracting mutual information of a dual system, unless you refuse to give any knowledge for that system at all.</p>

<p>> If the guardrails can be bypassed at, say 50x token cost (due to the agent also pursuing things you don't care about), then it's still pretty effective as a safeguard<p>Economic factors doesn't matter to powerful entities such as rival corporations, enterprises, and state power. It only matters to small players who have limited budgets. But I have to also pessimistically assume that Anthropic would go this way, because 1. it does not prevents (you can NEVER prevent) but discourages using it for exploitation, and 2. Anthropic can on the other hand, exploit those small and legit entities by making you pay more, but in exchange effectively enshittifying it. But Anthropic could care two shits about the benefits of us normal, small person. Anthropic have all the motives to do this.</p>

<p>Then reset the quotas as an atonement ;p<p>Seriously though, Fable was not that great facing a greenfield subject. It is excellent at oneshotting some math problems, but if you want it to do some cutting edge tech stuff, say like piecing together a new Crossplane XRD, by reading existing Helm chart and with application source code available. I still have to get a few pass for Fable to get it done right, and at this point I may consider making a skill for it. I even gave it the source code of the Crossplane itself and tell it to be careful about CRDs and data flow, but it is still pretty silly. Adaptiveness for Fable is still not great, and I think it is a well known problem for Anthropic, albeit all LLMs do suffer a lot from subjects they don't know and will hallucinate stuff very frequently.</p>

<p>Fun fact: the history of the (in)famous prefix NS in OSX -> macOS is a direct nod to the acronym of NextStep, hence NS. As NeXTSTEP was incorporated back into Apple, it was now re-appropriated as New System. Same thing goes to Cocoa and Cocoa Touch, as the legacy NeXTSTEP still lives on</p>
