Waymo's system, fueled by careful collection of a large volume of fully autonomous data, is the most advanced, large-scale application of embodied AI today. Very proud to see this level of engineering rigor tackling safe autonomous driving making the roads safer for everyone (and it has been nice to see various Google research collaborations with Waymo be a part of these advances!). The insights here are foundational for how we design and safely scale all complex AI systems. Read more at: waymo.com/blog/2025/12/demon…

Gemini 2.5 Flash is a high quality model and it's also... quick as a flash. Quick in more ways than one is the best kind of quick.
There was a lot of announcements at IO, easy to overlook the new 2.5 Flash. It's pushing new boundaries in capability vs speed!

New Stanford paper on working from home stanford.io/3JHqfrQ Some key points: 1) WFH is up 500% since 2019 2) Fully-remote is much cheaper, but can lower productivity 3) Hybrid improves retention, with no productivity loss 4) WFH will keep growing as technology improves

This essay on values is one of the clearest and most actionable discussions of org values I’ve read. Kudos to @Lethain for continually demonstrating what excellent looks like. lethain.com/setting-engineer…

TIL: ACID for database transactions is a pun because Andreas Reuter's wife hated sweet things and loved vinegar. Also, the world lost Jim Gray entirely too soon: I was fortunate to meet him once, but hadn't really seen a video of him talking about his work. Remarkably clear!
Born on this day in 1944, Jim Gray received the 1998 #ACMTuringAward for seminal contributions to database and transaction processing research and technical leadership in system implementation. In the video, Gray shares his thoughts on database transactions and the ACID test:

A Netflix binge is a temporary escape from languishing, not a cure. Passive engagement in a fictional world doesn't offer a lasting sense of meaning, mastery, or mattering. Flourishing depends on active participation in the real world: creating, connecting, and contributing.

Chaos Monkey was a tool for driving alignment around Availability. It's more effective than trying to 'command' engineers to optimize for Availability via hierarchy.

When people hesitate to give honest feedback on an idea, draft, or performance, I ask for a 0-10 score. No one ever says 10. Then I ask how I can get closer to a 10. It motivates them to start coaching me—and motivates me to be coachable. I want to learn how to close the gap.

I had the pleasure to chat with @ipapapa about the data infrastructure at @netflix. Tune in to hear how technologies like @CockroachDB, @RedisLabs, @cassandra and all the #opensource tools from Netflix work together as one data mesh. datastackshow.com/podcast/17…

So very happy to see the joy among my friends celebrating the first woman, the first Indian, the first Black American in the White House. Millions of children can now dream that it’s possible for them. Inspiration. 🇺🇸

This is a beautifully produced video where Paul and Bob talk about how they think about science and how much they love what they do, also how their minds work in different ways and complement one another. Show it to your older kids to inspire them!

In school and in life, success depends less on how much we know than on how much we want to learn. The purpose of education is not just to impart knowledge; it’s to instill curiosity. Intrinsic motivation is fueled by mystery, exploration, and meaning. nytimes.com/2020/09/07/opini…

How to pick a project worth pursuing: 1. Interest: do you think about it in your free time and bring it up in random conversations? 2. Importance: if we understood it, would the world be a better place? 3. Contribution: do you have something novel to add? #AcademicTwitter

So true. Life is messy. Life is annoying. The descent from fantasy to reality is often painful, but sometimes, more beautiful than you ever dreamed
If you want real things-- real love, real beauty, real achievement-- you have to accept that things that are real are imperfect. Things that seem too perfect or too easy are often superficial, fake, and explicitly designed to lure you into a mirage.
