There are a few pieces missing from this jigsaw puzzle of US presidents. Overall it creates a more relaxing puzzle experience.

Amazing interactive, challenging exhibits and audio tours at the Enigma Museum in Poznan, Poland today. It’s hard to believe that Polish mathematicians Marian Rejewski, Henryk Zygalski, and Jerzy Rozycki are not better known for their contributions to cracking the Enigma.

Just re-watched “This is Spinal Tap” yesterday in preparation for watching the sequel. Can’t believe the first headline I see this morning is that Rob Reiner and his wife were murdered. #RIP
