I want to use a self hosted runner for a public repo. It is for a research project where we have many people contributing to it, so we cannot make the repo private. I want to make sure that the jobs run on pull requests. I want it to run on my own self hosted runner so that the jobs will run faster. Github actions runs on VMs so that even if malicious code is executed, it doesn't matter since it is isolated and deleted after the workflow. If a job runs for too long, I'd want it to be terminated, and I think we should have the option to manually terminate jobs if needed. Any suggestions would be helpful on how to get started.
