OpenSnitch Is a Host-Based Firewall for Linux Desktops
Simone Margaritelli, the VP of Research at Zimperium, has created a Linux port of Little Snitch, a wildly popular macOS firewall application.
Named OpenSnitch, the Linux port works on the same principles of the macOS version, being a host-based firewall that notifies users when local apps are attempting to initiate new outgoing network connections.
Similar to Little Snitch's normal modus operandi, when this happens, OpenSnitch will display a popup, asking the user for instructions on how to deal with this new process.
All user decisions are saved as rules in local JSON files. Users can edit these rules later to fine-tune the firewall or import/export rules from/to other systems.

Several performance fixes are inbound on top of an important performance fix covered at the end of March where Clutter's text rendering code was causing frequent spikes in GNOME Shell's frame-time.

Plymouth Adds Device Rotation Support
Commits these days to Plymouth are fairly rare with this Red Hat developed project seeing its first commits of 2018 yesterday.
Plymouth doesn't seem commits too often since this Linux graphical boot system is largely in great shape, relies upon the stable DRM/KMS kennel APIs, and has largely hit feature completion for a simple graphical boot screen that is far better than the days of RHGB or alternatives. But a fair amount of new code did land yesterday in Plymouth for now supporting device rotation.
