You have to be comfortable with the fact that you will always have too many items in your issue backlog to do. You will always have parts of the codebase you don't understand. You will never be perfect, sorry. The goal is to know enough to get your job done, and be able to learn more when you need.

Once again, I gotta say: you cannot treat anything you’re feeding into an AI as anonymous. There are enormous ethics implications for, e.g. referees who are clearly uploading others’ unpublished papers without consent, let alone health care professionals or law enforcement

This is wild in many ways but... "DHH is known for controversial discussions, but this topped them all" I dunno, I'd argue the "murder the immigrants" rhetoric was a bit more controversial than what programming language this very rich lonely loser is using?

GitHub Actions + Rust's Miri can leak your secrets in CI 🧵 If you run Miri in CI: - upgrade to the 2026-09-22 nightly - clear caches - rotate any secrets that the `cargo miri` CI job had access to GPT-6 Astra helped find this 🦀

GitHub Actions makes it possible to cache directories between runs. Typical setups allow CI runs on main (and other branches) to write to cache, and PRs can only read from cache (preventing cache poisoning). Rust projects tend to speed up CI by caching binaries built by cargo install and sometimes the contents of target/.

PR CI can be triggered by anyone who can open PRs on your repository. GitHub requires maintainer approval for the first PR, but future PRs will rerun CI on every push. Anyone who has previously landed a change can trigger a CI run extracting information from cached target/ and then cover their tracks by pushing a second commit to the PR.

GitHub sometimes hides overwritten commits in its UI, making this kind of attack harder to detect. CI run logs and overwritten commits are also deleted after a few months.

When cargo miri is invoked, Miri needs to retain build-relevant environment variables between runs. The current code to do so achieves this by storing all environment variables to target/. This, of course, persists when target/ is cached.

If your environment contained secrets, these can now be accessed by PRs via the cache.

A lesson from decades of work on automation is that autonomous systems require continual monitoring and human oversight. System designers never(*) succeed in anticipating all of the ways that a system can fail.

Historically, automation tech has commonly made more work for people: the issue is WHICH people. Whether as an excuse for owners to increase the requirements for expectations in a given day, lessen the labor expected of men while raising the expectations for women, etc. "AI" isn't exceptional.

Nearly every general-purpose programming language is Turing complete. So ask not what you can do with a language, but what a language makes worth the effort. A short note on "effective expressiveness": www.inkandswitch.com/malleable-so...

Everything is possible. What’s actually worth the effort?

Sandboxing is indeed a "well-studied security problem since the early days of Java applets", but it very much remains a problem! Literally the best sandboxes still get exploited. I wonder if there was a miscommunication between the expert and the author here.
