ProtonMail Themes

This weekend I read a reddit post about theming ProtonMail with a little bit of CSS and the built in themes


mdadm, GPT and kernel; unexpected behavour

This weekend I encountered some rather unexpected interaction between mdadm, GPT and the linux kernel.

I had added a ‘new’ disk to my personal RAID5, growing it from 3 to 4 disks.

mdadm --add /dev/md0 /dev/sdd
mdadm --grow --raid-devices=4 --backup-file=/root/grow_md0.bak /dev/md0

Yubikey 4 as a GPG Smart Card

The Yubikey is a small USB token which can be used for OTP, U2F and CCID

I don’t use my Yubikey for anything other than CCID as I prefer to use Authy on my phone instead, I do however leave the OTP feature enabled so that udev gives the correct permissions to the card.

I generated my GPG keys on a LiveCD and backed them up to a USB Drive
