Legacy/archived lessons learned:¶
My lessons learned page started in the previous century as a way for me to track things that I learned in my travels. The notes got a bit sparse in the 2010s but I’m trying to recreate the process.
This directory contains the really old stuff. Does anyone really play with modem commands anymore?
