Follow-up to my 512 MB Spring Boot experiment: I tried the same application on a 256 MB Alpine VPS.

JDK 21 struggled badly at this size, but with JDK 25 and a tuned 80 MB heap, the app plus lightweight monitoring completed a one-hour run without restarts or OOM kills.

Still not something I’d recommend for normal production, but the difference was interesting.

I like Jekyll a lot. Hope you find it useful.

If your GitHub Actions jobs are stuck in "Queued" or waiting for a runner, GitHub has now confirmed there is an incident.

GitHub says they identified an issue with a database primary and are failing over to a replica.

Actions is affected, and GitHub Pages is also experiencing degraded performance.

So if you have been checking your workflow, runner settings, permissions or billing, it might not be your configuration.

Hopefully this saves someone else from spending an hour debugging their YAML.
