Your cloud SI is smart, but it can't touch your computer. Homing Pigeon fixes that: tell your SI to complete a task and it will do it on your machine (Linux/macOS/FreeBSD/Windows), and the results return so the SI can iterate: run the tests, read the failure, fix, repeat. Think 'GitHub self-hosted runner, but the control plane is email.' Python 3.9+, standard library only, no dependencies. Jobs are HMAC-SHA-384-signed JSON carried by email (protocol v2); a local Oracle model reviews what comes back before your SI sees it. By design it executes signed jobs with the runner account's privileges: run it on a machine you can afford to lose.

VM is a mail reader that runs under GNU Emacs. It was written as an alternative to the Emacs RMAIL mail reader by Kyle Jones. VM is highly configurable and easy to use. It supports POP and IMAP mail servers, understands MIME, and handles mail folders in the standard UNIX mailbox format and the BABYL format used by the RMAIL mailer. It has a powerful virtual folder facility to facilitate searching as well as more advanced handling of multiple mail folders. This site exists to continue VM development after version 7.19 as a community project.
