University of Toronto ☛ There are multiple uses for metrics (and collecting metrics)
The first and obvious purpose is actionable metrics, things that will get you to do things, often by triggering alerts.

Felix Feldspaten ☛ ssh authentication via Yubikeys
I recently played with my Yubikey to establish them as second factor for my ssh keys. The process is straight-forward, however it took me some time to go through Yubico’s documentation. Here I write the process down in my own words.

From OpenSSH 8.2 and 8.3 respectively (for resident keys) onwards, yubikeys are supported. I do only require them for Linux, although the documentaton mentions some not-officially-supported-but-should-work methods to get it also working on Windows and MacOS.
