News, of the release of OpenSnitch - the GNU/ Linux port of Object Development's much beloved LittleSnitch - a native macOS Application Firewall is the big news around our locale today. As of the date of this post, OpenSnitch is in Alpha release state, with the caveat: 'Warning: This is still alpha quality software, don't rely on it (yet) for your computer security.' Additional information is available via the OpenSnitch GitHub Readme. H/T
