I personally always have one USB stick with me that has a live usb boot of Fedoraon it, but I just saw the new video from Linus tech tips and thought about extending it a bit.
He mostly talked about windows tools, but I think I will add
- https://www.ventoy.net/en/download.html for maybe an additional Linux light version
- https://github.com/TheWaWaR/simple-http-server if I have to share files from a broken Computer or so.
What are you using or do you have recommendations?
I used to carry Tails around on a tiny USB drive in case I wanted to do something on an untrusted machine, but a) the USB device I chose got stupidly hot, and b) I never actually needed to use it since I carry a smartphone everywhere, so I stopped.
