A team of brilliant people who work at YC shipping products internally and externally.

RubyLLM is very easy to use. Made extensive use of it for a project last year. Drawbacks are it was difficult to instrument for true trace observability and it has a pattern where …

Interesting suggestion, thank you!

I wouldn't assume that a VM will give you complete security against a determined AI. yolobox started as a way to prevent accidental `rm -rf ~` and has expanded into a set of tools …

Docker was only exposed later, after I realized that any sufficiently determined AI could break out of the container, and attempts to contain it were a waste of time. Also note tha…

The docker compose stack for the applications is spun up on the host. The agents have access to the docker socket which means they can talk to docker from inside their sandbox and …

Did you read the post? That's exactly the problem I just solved.

VMs bring greater isolation but they're a lot heavier and slower. The agents just use github for synchronization here, though I've been considering building some kind of todo list …

Hard drives are cheap and I haven't approached the limit yet. So I left this as a future optimization.

Author here. Three months ago I posted a Show HN for yolobox [1] - a sandbox for running AI coding agents without them being able to nuke your home directory. Since then I've been …

I think you're making some hasty generalizations here. They don't "uniformly" cover for their colleagues. Do you expect the police service to be perfect and never make mistakes? Ca…

County was not a typo. It's awful whenever there's an overuse of force in the USA. I'd recommend watching a few police bodycam videos on youtube before judging them wholesale thoug…

Agreed. Flock has been a key contributor in solving numerous crimes. I'm happy for Flock to be in my county and would like the police to have more access to technology like this, n…

Who cares that the code is garbage? As the models get bigger and more powerful it will be trivial to fully refactor the whole codebase. It’s coming sooner than you think.

MS treatments tend to take 3 forms: - immune reset (sledgehammer that can “cure” diseases like MS but with many side effects and potential complications) - immune suppression (supe…

Awesome to see a bash-only method of solving this problem. Also like that it alerts on attempts to read restricted stuff. I built yolobox to solve this using docker/apple container…

I wrote an article about this a few days ago that has been gaining a lot of traction: https://finbarr.site/2026/02/12/in-defense-of-saas.html Point solutions are going to be free. …

The whole idea was a bit of a joke and a reflection on how ridiculous it is that people get in trouble for failing to regurgitate the correct takes when certain events occur. It’s …
