I might take the PCEP exam to demonstrate my knowledge in Python. For now, I have taken a CISCO course called Python Essential 1 and here are some notes, curiosities, and code that I found interesting if you are not a Pythonista.

This is one of those things that I do every day, and the flow is very boring: Open Quicktime, cancel the box dialog, Go to File > File > New Movie Recording, and then select the device. I mainly use it to view the signal from a USB video capture device, which works much better than doing it via VNC, Remote Desktop, or similar. In addition, these types of capture devices are very cheap.

Just a quick tip If you want to read a Medium article for free, cuz you don't have money to pay for a subscription or you don't want to create an account.

If you want to run a script for example, after apt update on Debian, you can use the apt hook system. This is useful if you want to perform some other action after the update. In my case, I need to run a script and re-install the Vulkan driver on Raspberry Pi, because apt update break it and the system can't open the Desktop environment.

Sometimes I think I'm the one who has problems with the NTFS/exFAT partition on macOS. I have to unmount and clean it, because exFAT is the file system I use on a Raspberry Pi acting as NAS using the great DietPi OS.
