Hey there ;P I’m writing this blog to share some of the cools out of my life (mostly nerdy stuff xD). Right now I’m studying Computer Science in Munich and am pretty enthusiastic about Privacy.

I use NixOS btw

Noctalia V5 NixOS

Sat, 27 Jun 2026 18:31:21 +0200

Currently Noctalia v5 is still in the alpha, but I still decided to adapt already, as it works better with my current setup. I’m using an Impermanent NixOS System and didn’t want to persist the .cache folder (really don’t want to, caches should be cleared …). And unfortunately Noctalia v4 stores the current Wallpaper in there, so if you don’t persist it, each restart Noctalia has the Wallpaper set to the default one with the own …

Nix Impermanence NoExec Root

An impermanent NixOS Setup is something, I personally I really enjoy, as I don’t like preserving everything on my system forever … Persistence Opt-In is the best approach.

And recently I came across a nice Blog about hardening NixOS from Xe Iaso’s blog. And well one thing especially seemed cool, so I wanted to share it.

NoExec for the Root FS

At the bottom of the blog is a part about having noexec for the root fs (which is a tmpfs anyway). Since all programs in NixOS life anyway in /nix/store and /nix is its own partition in the typical Impermancence Setup (I won’t talk about how to this now, as there are already many good blogs discussing this, and showing how it’s done; if you want to see my own setup, check my Codeberg out). So only the /nix parititon needs to be mounted without noexec, the rest can be noexec.

Starting a blog

Thu, 25 Jun 2026 22:00:11 +0200

Recently I’ve come across some pretty cool blogs, like the one from マリウス, or some cool Nix related blogs, a lot of them linked in this Nix Webring Project. I really enjoy reading a lot of these posts and doing some of the projects shown there myself, or finding inspiration for my own setups etc. So I thought maybe I should also start a blog, as I do certain things still different in the end or find some nice tweaks I just wanna share, as I’ve not seen them so far.
