From my own post: cross-posted from: lemmy.world/post/47418159

I’ve just set up bees on my laptop.

• It’s been running for 40 minutes now
• I went from 28G to 58G free space on my 2 TB SSD
• Without deleting anything

I’m genuinely amazed. Idk why, but I thought this was more of a gimmick for some reason, but nah it works well.

Can highly recommend :3

See github.com/Zygo/bees for the project if you wanna learn more.

Here’s all I did on my system (NixOS), see !nix@programming.dev

1. I put this in my NixOS config:

services.beesd.filesystems.root = {
  spec = "UUID=dfabb360-7fde-4b06-a884-03c8d217d877";
  hashTableSizeMB = 8192;
};

1. I ran this command

cd /etc/nixos && sudo nixos-rebuild switch |& nom
# tho just running sudo nixos-rebuild switch in the correct dir would be sufficient

And it just started giving me more space on my disk :3

PS: it’s been 49 minutes now, and I’m at 72G free 🎉 (the CPU has been maxed out the entire time, keep that in mind)
