New in Claude Code: your sessions can now message each other. Instead of having to re-explain yourself in another session, you can now tell Claude to do it. It sends a summary (not your history or files), and the other session picks it up mid-task.

Tomorrow will be my last day at Google after 27 years, and watching it grow from 25 people to 190,000+ has been an amazing journey. Below is a note I shared with many people internally at Google today. An excerpt is: It has been an absolute pleasure to work with you and to help build some of the most widely used and impactful products of all time. As a kid, I dreamed of helping build software that would be used by many people, and Google now has thirteen products used by more than a billion people (amazing!). Our work has had a tremendous impact in the world, and I have been lucky enough to collaborate and form friendships with many colleagues that I deeply admire, respect, and enjoy. It still brings me joy every time I see people out in the world using our products to find information, handle email, translate documents, watch videos, learn new things, navigate and understand the physical world, browse the web, use their phone, run large-scale computations on our infrastructure, ride in an autonomous vehicle, or perform complex tasks with the help of our AI systems. I hope you all share this sense of joy, because it is a shared accomplishment! Thank you to all of my colleagues at Google over many years! Now I'm excited to go start @DiscoLoopAI with my longtime friends and colleagues @Sanjay_Ghemawat, @OriolVinyalsML, and @quocleix. (Updated post: slightly redacted to not have some personal info)

Airdrops are a fascinating initial use case for ZK / blockchain-based identity / credential / attestation frameworks. The goals of an airdrop are: (i) distribute to community members [and not randos who will all immediately sell] (ii) reward contributions to the project (iii) be reasonably egalitarian [but some disparity is ok] (iv) resist extractive/adversarial farming These are exactly the properties that identity / credential / attestation frameworks (eg. see ideas in vitalik.eth.limo/general/202… ) are trying to achieve. Hence, for anyone building such frameworks, it makes perfect sense to use token issuance as an initial use case to beta-test and refine their work in an adversarial environment.
