Objective-See: An Open Source Project Org for Apple Privacy and Security

While searching for small tools today, I found they have built a bunch of open-source software for macOS, mostly related to privacy and security.

KnockKnock: See what background processes, daemons, launch items, kernel extensions, login items, browser plugins, and more are on your Mac. Much more detailed than “Login Items” (some software auto-starts in other ways).
LuLu: An open-source macOS network firewall that lets you control each application’s network connections in detail (similar to Hands Off!).

sips -c <height> <width> <image> crops the specified image to the given dimensions (relative to the center of the original image).

sips -r <degrees> <image> rotates the image by the specified degrees.
