Running gnome-control-center in i3 session
Here is the issue: I’m running i3 on the desktop, but still need to have GNOME Evolution to work with different email accounts. Evolution is configured in GNOME Online Accounts, but unfortunately GNOME control center wouldn’t start properly in a bare i3 session. The solution is easy:

Since I started using kerberos.io, I had to decide how to install it on my Raspberry Pi 3 running Arch Linux ARM. First I tried to repackage the official .deb for pacman: PKGCONFIG.

Finally, I’ve come to yet another solution: running the genuine raspbian contained systemd-nspawn to enable official builds following the guide.

Luckily there is an AUR package with LTS kernel linux-lts49. Unfortunately, it can’t be built in

Welcome Language Server Protocol
I’ve put a lot of effort to get YouCompleteMe and rtags configured and running: deployed compactly, updated automatically, adapted to vim, managed. And they served well until I found a better solution: language server protocol (LSP). It turns out to be as robust as simple to configure nowadays.

Arch Linux configuration management
It turns out that tracking tweaks to the system, Arch Linux in my case, is a common concern. And it has already been solved by aconfmgr. This is a shell script, which calculates what has changed in the system: installed or removed packages; added, removed or changed files.
