Best Technical Explanation Video?

I came across the following video while doing research on how to use Docker securely esp. regarding mounting volumes as a non-root user.

Spoiler: it’s complicated and there has been a number of explanations and discussions on this topic including one from about 10 years go. Yep!

I already knew the solution to my problem - running Docker in Rootless mode. But in this short ~33-minute video, Liz not only explains the problem but also the solution in a very clear and concise manner. And how it is implemented in Docker by actually implementing it live!

The last one I remember someone explaining a technical topic in such a manner was What the heck is the event loop anyway? by Philip Roberts.
