Much of the guide will be focused on OPNsense configuration since it lies at the core of the network infrastructure, but managed switches and wireless access points will be discussed as well.

ChatGPT Desktop App – Unofficial open source OpenAI ChatGPT desktop app for Mac, Windows, and Linux menubar
Although I have considerable misgivings about trusting AI for anything at this point in time, given its propensity to occasionally just make up answers that are total bulls&!t and invent facts out of thin air, a lot of people are still playing with it, and this software could make it more convenient to do so. Note that I have not personally tested this, so install and use at your own risk.

LuLu – a free alternative to Little Snitch?
If you use MacOS and you would like the functionality of Little Snitch but don’t want to pay for it, this might be an alternative to consider. I haven’t tested it, nor have I done a feature comparison between LuLu and Little Snitch, so this is just to note that it exists and nothing more.
In today’s connected world, it is rare to find an application or piece of malware that doesn’t communicate with a remote server.
LuLu is the free, open-source firewall that aims to block unknown outgoing connections, protecting your privacy and your Mac!

Open source video captioning on Linux
In a perfect world, all videos would have transcripts, and live videos would have captioning. It’s not just a requirement for people without hearing to be able to participate in pop culture and video chats, it’s a luxury for people with hearing who just prefer to read what’s been said. Not all software has captioning built-in though, and some that does relies on third-party cloud services to function. Live Captions is an application for the Linux desktop that provides instant, local, and open source captioning for video.
