Took me some time to learn how SNMP v3 (and SNMP in general) works. But now I have nice dashboards.

When using docker in LXD/LXC, the FS performance is really really bad.

I needed to run Docker in LXC containers on my Ubuntu servers.

I'm now a heavy user of Draw.io a great piece of Free software from jgraph. However sometimes I need to use it offline… Here is an easy guide on how to use it locally.

I'm moving all my old file-based ssh and gpg keys to a YubiKey 4 hardware key. This post will get updated with a few notes along that migration. It also covers how to use pass and pass-tomb with these. And then I fell down the rabbit hole of using those keys everywhere…

Tonight, I played with git hooks. Because I wanted to be able to regenerate the website remotely just by doing a push to a specific branch of the website repo.

I use Notmuch to manage my emails (and that's just wonderfully fast) and use the Emacs frontend for it. But when I wanted to save attachements, it was not that easy to create folders. I had to exit the save, open a terminal, a dired or whatever create the folder… I use Helm for managing completion in emacs (and that's a nice piece of software too).

To avoid that and with the help of Sacha Chua, I managed to add a shortcut in helm read file:
