how can we cut our CI times by 50–90% and reduce our dependency on #github actions, securely and cheaply enough for a large public #rustlang codebase?

we did exactly that for @servo by building a self-hosted runner system that does virtual machine orchestration under the hood, all for barely 400 EUR/month!

@shuppy @servo putting Mozilla to shame more and more everyday 😆
@tootbrute @shuppy @servo for the record, Mozilla developed in-house the best CI system I've ever had the pleasure to use, but the Rust project didn't want to use it.
@tedmielczarek @shuppy @servo i'm just impressed at how much servo is doing with so little $$$. scrappy startup vs. mozilla which is now a million dollar (billion dollar?) company
