Good question, maybe it’s the size of coal or the thickness/shape of the ceramics, but i found they taste less of coal.

Yeah i feel that, i only smoke with charcoal filters(for 3+ years) :D Have you tried the purize filters? I find they dont have as much of a taste of their own. Sadly not every kiosk or gas station offers them but headshops usually have them.

I’d say time well spent. Good job! :P

I have a yubikey and use their pam-module for 2FA on sudo and ssh. Took a bit of time to configure, but now it works like charm: https://wiki.archlinux.org/title/YubiKey#Linux_user_authentication_with_PAM
