Yesterday I was fortunate enough to go to my first-ever World Cup game, with my long-time colleagues/friends Oriol Vinyals & Quoc Le and their spouses). I present to you a 43 second multi-part drama: Promising cross Maybe overhit? Nico Williams' knock down Ferran Torres' strike ....

Cross-country skiing gold medalist Jessie Diggins: “I'm racing for an American people who stand for love, for acceptance, for compassion, honesty, and respect for others...For everyone out there caring for others, protecting their neighbors & meeting people with love, every single step is for you."

A photo of cross-country skiing gold medalist Jessie Diggins, who said in a social media post, that her motivation comes from the people she believes represent the country’s best values. She stressed that her focus is on compassion and inclusion.

“I'm racing for an American people who stand for love, for acceptance, for compassion, honesty, and respect for others. I do not stand for hate or violence or discrimination," she said. "I get to decide who I’m racing for every single day, and how I want to live up to my values. For everyone out there caring for others, protecting their neighbors and meeting people with love - every single step is for you."

Diggins concluded by saying, "You are the ones who make me proud to carry the flag, and I hope I can bring you joy over these next few weeks."

They're never looking to be able to take a life of individuals."

It’s genuinely wild that the United States spent decades building an elaborate rules-based international order which de facto cemented its permanent status as the dominant global hegemon, sustained by ideology rather than might, and now is just blowing it all up for literally no reason

My colleague Sanjay Ghemawat & I have done a fair bit of performance tuning of various pieces of code. We wrote an internal Performance Hints document ~2 years ago as a way of identifying some general principles & we've recently published a version of it externally. Doc: abseil.io/fast/hints.h...

We’ve pushed out the Pareto frontier of efficiency vs. intelligence again. With Gemini 3 Flash ⚡️, we are seeing reasoning capabilities previously reserved for our largest models. This opens up entirely new categories of near real-time applications that require complex thought. More in thread ⬇️
