Welcome. If you made it here, that means we are friends. It also means we probably worked together at some time. I hope both are true.
Honestly, no rhyme or reason for this collection of stuff. It's just (most of) everything that I happened to have saved over the years. If anyone has anything else they would like to share, let me know. Happy to insert a link.
Could I be doing more productive things? You bet.
But a few minutes reminiscing is what we might need right now.
