so glad I can be learning Rust from the experts at Adobe, their beautiful elegant code is really an inspiration 😊

It shows Epstein’s world in his own words: an unfiltered look at how his operation worked, who enabled it, and how Ghislaine Maxwell stayed at the center of it all.

The State of Illinois at this time has received no requests or outreach from the federal government asking if we need assistance, and we have made no requests for federal intervention.

Sometimes I see people like 20 tweets deep into an argument with Grok. Like, what are you doing brother? You are trying to win an argument with a vending machine.

Tom Lehrer - We Will All Go Together When We Go YouTube video by The Tom Lehrer Wisdom Channel

Tom Lehrer died today. He was one of the great comedians our culture ever produced. Without Tom, there's no Weird Al, probably no that entire branch of comedy.

He went alone and beat the odds.

I had to look it up, and while there were some variations coming from a few different places in North America leading up to the modern version, the wiki says this:

“Cornhole as it is now known originated and gained popularity on Cincinnati's west side…”
