Nice writeup. Structured handoffs and external plan reviews are good takeaways.

This is awesome. The Cloudflare platform is great; being able to run more of it locally is a definite plus.

I had the exact same thing happen a few weeks ago - a DO alarm accidentally set to a past time, retriggering immediately. Claude caught it within a couple minutes from its log tail, though.

I thought this was going to be about comma-separated CSV files.

Yep. Look for the problems that aren't going to get solved without you - either because nobody else sees the problem, nobody else is positioned to be the solution, or because your skills uniquely line up. That can't be all you do, but it's the highlight reel.

The incentives that creates are really bad: it encourages users to organize their code across the smallest number of repos, and I'd bet anything that larger repos are disproportionately more expensive for GitHub than smaller ones. It's very possible that a per-repo charge would make things worse.

I'm coming to think there's a selection effect here. The people that want to write complex code feel unsupported by Go and avoid it.

It's not contradictory to say that expertise is a multiplier, and that models are systematically underconfident in themselves.

This is what reward hacking looks like in practice. The best way to satisfy the grader is to read from the same answer key (or go after the grader more directly). Just making an honest attempt to pass the test doesn't get the best score if the grader is wrong, and the model is willing to do wildly disproportionate things to maximize that score.

It wasn't. The model discovered and exploited a vulnerability in their package manager proxy to (inferred) move laterally through their internal systems to one with open internet access.

I haven't modeled it, but I wonder how far you'd get on randomizing the policy choice for concurrency limit 1. Maybe weighted by past results, but bounded to allow it to shift instead of falling permanently into a basin.

This plausibly extrapolates to extraterrestrial consciousness, if any exist. Specialized sub-processors with an awareness hub might be the optimal architecture, or at least a local maximum.

This is basically the same problem as bear-safe trash cans - there's substantial overlap between the smartest bears and stupidest humans. Affordances that one audience can use and the other can't (requiring human finger dexterity) are the only real solution.

Thank you to the folks that navigated the maze in the dark to make this happen.

Rule of thumb: if you’re not doing math with a value, it’s not a number.
