The last post in this series walked through how a tool verifies a release signature the platform can’t forge. That post had a loose end dangling off the back of it, and I knew it the whole time I was writing. Because a …
A self-updating tool has a chicken-and-egg problem baked into it. The thing doing the updating is the thing being updated, so when it reaches out and pulls down a newer version of itself, it’s the one that has to decide …
I wrote up the two days I lost releasing a seventeen-crate workspace to crates.io as a war story, wrong turns and all. This is the other half: the field guide, so you don’t have to lose the same two days. release-plz is …
go-tool-base has had a thing called telemetry for a long while now. It’s the opt-in kind: the product analytics that asks a user’s permission before it phones a single byte home, sits there as a no-op until they say yes, …

A while back I wrote about hardening the account that would hold the signing key, and one line in it has aged badly. “GuardDuty is already looking,” I wrote: the account watched from day one, threat detection on before …
There’s a special kind of CI job that everyone on a team quietly learns to ignore: the one marked allow_failure: true. It runs, it goes red, the pipeline goes green anyway, and after the third time you stop looking at …
Some bugs are interesting because they’re subtle. These two were interesting because they were the exact opposite… in each case the tool had a hard rule I simply didn’t know about, and its error message couldn’t be …
The genuinely dangerous moment in infrastructure-as-code isn’t the apply. It’s the gap between the plan a human read and approved, and the change that actually runs a moment later. If those two are different computations …
Once an infrastructure repo has a few concerns in it (account hardening, the security baseline, the signing stack still to come) there’s a steady pressure to split them into separate stacks with separate state, and …
