The clash of holidays begins! Will a tiny fib, or two, create holiday bedlam? Likely. Set in Colorado, a workaholic executive books a snowy getaway to The Snowflake Inn. Enter a handsome mystery man, sullen teen, charming innkeeper, and more. W/all the Christmas vibes!

Yes, heat dissipation in space is harder. But when a bunch of Material Science PhDs who've been engineers at SpaceX and Airbus come and tell you they think they've figured something out, it's probably worth taking a shot. Even if there's 1% chance they're right.

Hyperspell (@hyperspell) gives AI agents memory. It connects to Slack, Gmail, Notion, and Drive, so agents get context and remember what they learn. Congrats @conor_ai and @maebert on the launch! https://t.co/WkfMWkUs5p
