    My Homelab Is Not A Mess Anymore

    A little over a year ago, I made a bit of a long-winded rant regarding on how my homelab is a mess.

    GrrCon is an information security and hacking conference in Grand Rapids, Michigan that I and Sara attended at the end of September. I had a wonderful time at GrrCon 2023 and it is my goal to be there every year here in after.
