In April, '17, @jsomers of @NewYorker reached out & said he wanted to do a small profile of me & my longtime colleague Sanjay Ghemawat, watch us work for a few hours, maybe dinner, etc. It came out today. I think it captures our working style really well.

Coding together at the same computer, Jeff Dean and Sanjay Ghemawat changed the course of the company—and the Internet.

Another step along the path to practical quantum computers!
New breakthrough quantum algorithm published in @Nature today: Our Willow chip has achieved the first-ever verifiable quantum advantage. Willow ran the algorithm - which we’ve named Quantum Echoes - 13,000x faster than the best classical algorithm on one of the world's fastest

AI/ML-based system infrastructure that learns and dynamically adapts to changes holds incredible promise, but building models deep into the systems stack has been a longstanding challenge. Here we discuss our approach that enabled us to deploy this in Google's cloud data centers.
Scheduling virtual machines (VMs) is like a puzzle game with disappearing pieces. Here we present LAVA, an AI-based scheduling algorithm that continuously re-predicts & adapts to the lifetimes of VMs to optimize resource efficiency in cloud data centers.

Another great example of how ML can be used to improve computer systems, by learning how the system is actually being used (in this case by predicting VM lifetimes for optimizing their placement). Nice work, Pratik Worah and @martin_maas and coauthors!
