@lillecarl:matrix.orglillecarlI found a tool that I decided to try yesterday and regret I didn't try earlier. It's called optnix, it's essentially a terminal version of search.nixos.org for options.16:31:54
@lillecarl:matrix.orglillecarlhttps://asciinema.org/a/cEbCAqfEwt0pOAPBDBVLLLj5b Here's a quick asciinema so you can check it out without installing, and they publish as a simple flake, just nixpkgs as a dependency which is nice. It's really useful when you're developing your own modules since it evaluates your own instance of your options rather than a predefined one. So it makes building option hierarchies and actually using them a lot easier, I bet a lot of you use either search.nixos.org or mynixos.org a bit and this is pretty similar :)16:38:42
@markuskowa:matrix.orgmarkuskowaThat's cool! What's the URL for the flake?16:54:31

@aevl:matrix.orgAndersHi all! Just wondering if there are any companies in Stockholm using the Nix ecosystem? (Would be interested in working at such a company!)14:58:58

I learned how to do a really cursed thing today: edit /nix/store paths

sudo unshare --mount bash -c 'mount -your /nix to /nix'

My goal wasn't to edit storepaths but to hardlink to the store, which requires being on the same mount point (which /nix/store isn't because it's RO bind-mounted over itself)

unshare --mount creates your own mount namespace (ish) where you get a clone of what is already, but you can mount over things without disrupting any other processes.

@markuskowa:matrix.orgmarkuskowaI hope everyone had a great summer. Let's start up the new meetup season on Wednesday the 27th at the Nordic light hotel. Give it a thumbs up if you are planning to join.20:13:26
