We are sometimes hyper-critical of technology, but we really do live in an age of miracles. I am currently watching a live stream of our daughter's college diving meet, while texting and sharing videos with my wife who is physically attending… infosec.exchange/@hal_pomera…

Wow, yesterday's Linux DFIR command line trivia scared everybody off!
Let's start with this string:

Lots of folks chimed in with the correct answer to yesterday's Linux DFIR command line trivia, but 🐘xuf@geraffel.social was quickest off the mark.
