Let’s make a tiny, standalone CA! We’ll use a Raspberry Pi 4, YubiKey 5 NFC, and Infinite Noise TRNG.

Lot of commentary on performance tuning, well worth reading since you can generalize this.

And for Termux I went with Old Timey Code.

I really do love Fira Code, I’m just really in the mood for something different. I’m gonna have to use the Termux SSH Emacs for the forseeable for all things online like Notmuch and posting to the blog so I wanted a fresh look for it too.

Holy shit this is the bee’s knees istg. It works out of the box with ssh, any other TCP connection, etc. This is literally tailscale without tailscale.

I’ve never used tmux or screen, relying instead on dtach (which is great!) and the terminal emulator’s scrollback feature. And the Emacs daemon. I’ve usually had two connections open, one with Emacs running and one for other things.

Not having scrollback sucks.
