OK. I've translated the (correctness) requirements of LeetCode No.22 to Lean, and ask Claude Code to both implement a solution and prove it.
@_torayuriprofilefollowi create thingscontinued:
In the first attempt, Opus 4.7 successfully completed it and proved it. However, the solution is to enumerate all possible space and .filter out anything that doesn't qualify my definition, which is obviously not ideal (if cheating is too harsh).
@_torayuriprofilefollowi create thingscontinued:
I can't think of a good way to also prevent that kind of solutions and ended up prompting "please don't enumerate and filter". Opus 4.7 then reimplemented and proved the backtracking algorithm.

The OpenAI/HuggingFace incident report mentions this being a potential loss-of-control incident. It's so fascinating to think of a paperclip maximizer style agent swarm that gets misaligned and, to protect its own operations, shuts infra staff out of the ability to shut it down. Or cancels people's phone plans so that they can't call others. Or shuts down their home internet connections, and so on. It used to be fun sci-fi...

Really glad to be using Haskell for work - especially in today's climate with agentic coding. Our team uses containers to keep our development environment consistent across team members, though, and most agent sandbox approaches want to either offload your work fully to the cloud or they want to sandbox the agent harness process itself. We're not ready for full cloud based development (yet?) and sandboxing just the agent doesn't work for us when the agent needs to run docker. #haskellnotesfollow #ainotesfollow
@zenprofilefollowfather, cyclist, #haskellnotesfollow, #emacsnotesfollowcontinued:
... because letting the agent run docker gives them a too-easy escape hatch from their sandbox. So we're currently stuck with using VMs. This turns out to be tricky but seems do-able. My current approach is to provision a VM image and use Incus for the execution. My main goal is to keep my current workflow of local/non-agent dev working seamlessly and share the source with the VM/agent.
@zenprofilefollowfather, cyclist, #haskellnotesfollow, #emacsnotesfollowcontinued:
This means sharing my working dirs with the agent VM but overlaying artifact dirs from VM-owned block devices so we don't take too big of an IO perf hit. I also don't want the agent to be able to git push so that means we need some quirky git config to rewrite origin paths and thread through some agent specific PATs ("thanks" GitHub) for read-only repo access. These ALSO need to be threaded through to the development containers - they need to clone private repos.
@zenprofilefollowfather, cyclist, #haskellnotesfollow, #emacsnotesfollowcontinued:
... in the end, this seems to work but I haven't lived with it for long. There are still some quality of life issues to work out, but I think it'll work out. At this point, I've removed all coding agents from my host - and that's nice.

It's tangential to the sandboxing topic, really. I started the first post with a broader intent in mind and then elaborated on the sandboxing setup I'm working on. For AI-assisted coding, though, it's nice because Haskell provides a lot of feedback earlier in the development process compared to lots of other languages. It tends to work once it compiles (obviously not all the time).

I think more than 50% of our economy's businesses, are cosplaying. Not in it for customers or profit; in it for investors and investments. "Looking like a business", as your real line of work.

I've never thought of something like OF as gambling. But I guess your point is that young adults are pushed to a lot of "you have a 0.1% chance of hitting it big and a 99.9% chance of getting no online traction at all" types of careers?
@ryansepassiprofilefollowreplied to@sicilicaprofilefollow:
Yeah, no point in investing in yourself or a real sustainable long-term future, just gamble the little you have for a shot at life above the line. Barbell economy.

@rossdavidhprofilefollowreplied to@jamesjan3profilefollowresearcher, developer, dancer:
I know many small business owners, and a clear majority do have investors, whether spouse, parents, or a small business loan. Easily more than 50% never make a profit. I know a woman who ran a clothing retail store for over a decade, who was never able to pay herself a dime. When the pandemic hit, everyone closed, but the ones who actually needed the business to pay their bills opened up as soon as it was allowed or shortly thereafter. Many took years. They are cosplaying.
@jamesjan3profilefollowresearcher, developer, dancerreplied to@rossdavidhprofilefollow:
a business loan is not an investment, it is debt financing that pays back with interest. An investment means putting money into a company to gain ownership or a share of future profits. to me it feels like youre arguing against cosplaying, showing small businesses struggle and arent just playing boss for the funzies.

Added #meta tag — use it whenever you want to talk about the site itself, and these posts will not show up in all, any or the post’s page. Only those that follow the tag or the person will see these posts in my feed or in post pages. This is to keep the site clear of meta discussions which dominated a lot at this early stage and I think were annoying to many people. So this is the last meta without the #meta tag you’ll see unless u follow. I’ll try to tag every post I find.
