TIL that the linux blkdiscard command exists and can make a ssd show as completely erased without spending an hour overwriting everything. Was useful for getting rid of some filesystem metadata preventing reuse of a drive.

Screenshot showing a dell idrac booting Talos Linux (the kubernetes distro) and my computer's statusbar showing the time as 3:00AM.

Is something going on with Discord for anyone else? I was required to change my password when I tried to login, after that I got 3 emails saying `We removed a violation` when I haven't broken TOS and never received a violation warning. Asked some friends who had no idea and said I wasn't hacked.

am I alive? I think my PDS is working again after committing some nix crimes, force writing stuff in /nix/store, to my defense it was because I couldn't even connect to the server because it was assuming the wrong network interface name as I changed hypervisor.

IPv4 is legacy technology and needs to be treated as such. I just wanted to VPN into my home network (headscale subnet router) when travelling and ended up with a subnet collision under IPv4. Obviously my IPv6 ULA has a very low chance of colliding and worked perfectly.

NixOS people, is there really not a way to make it so stuff can build even if a substituter is offline? Like some sort of an optional substituter? #nixos
