Personal wiki
Welcome to my little knowledge graph! I try to write down concepts as I learn and understand them to solidify my own grasp of them. For now, this wiki is focused on wireless communications and related math and programming ideas, because that's what I have been spending most of my time on recently.
This site is written in and published with emacs, using org-mode and org-roam.
I can't claim to be an expert in this field, but I try to write things down after I have a personally satisfactory understanding of them, so if you have any questions about something here feel free to contact me!
