Bonfire Social 1.0 is live! A federated, community‑first social network built on the modular Bonfire toolkit, and it’s only the beginning.

ls-lint

An extremely fast file and directory name linter - Bring some structure to your project filesystem

Great article on using GitHub as a workflow platform:

Can absolutely recommend for security workflows and management as well!

@raesene True, quite some good stuff out now!
@raesene Hm, the ones I looked at were quite lacking :D But that was two days ago and reliable exploit did not take that long. Will have a look, thx :)
