Phone bans in schools motivate kids to read. When a Kentucky district eliminated phones, students checked out 2.3x as many books from the library. At one school, twice as many students borrowed books in the first month as all of last year. Without smartphones, kids get smarter.

I'm glad to see organizations like bridgeusa.org exist. @BridgeUSA_ Nuance and real conversation where we can listen and explore different perspectives is what we need most. We are far more alike than polarizing social media, pundits and those in charge would like…

Loving Founders Cafe by @AngelList ! Such good energy and a great idea!


Introducing: Founders Café from AngelList The average café is simply not conducive for deep work. They’re not open late, Wi-Fi isn’t fast, there aren’t enough power outlets and they’re not open on the weekends! We’re solving this problem by turning the first-floor of our…

This is a great step forward. There will be more to do to understand business logic flaws, but let’s be real, there is no shortage of code level vulnerabilities and this is needed.
Claude Code can now automatically review your code for security vulnerabilities.
Wild how fast the future is coming at us - talked with ChatGPT this morning about time dilation and relativity - added features to my custom nutrition app via mobile on Replit and redeployed while on the move - grabbed a self driving car to get across town for my next meeting
Dang. AI goes rogue and nukes the entire database. The “oops I panicked” part is particularly distressing!
.@Replit goes rogue during a code freeze and shutdown and deletes our entire database

How a Hacker Became Twitter’s First CISO: Michael Coates on Cyberse...
It’s official! Today I signed legislation to make @GCFC_SF the newest professional team in SF. GCFC will be putting in $10m to privately fund improvements to Kezar Stadium, which include a new field, new seating, and a new scoreboard. Public access will remain the same.


OK, I’ve seen enough of these smug “but Israel has previously cried wolf about Iran's nuclear weapons ambitions” takes (like @jonstewart does here), so let’s debunk this charge: 🧵 /1

If you use "AI agents" (LLMs that call tools) you need to be aware of the Lethal Trifecta Any time you combine access to private data with exposure to untrusted content and the ability to externally communicate an attacker can trick the system into stealing your data!

I’ve been mentioning the end of “truth” is imminent for the last 18 months. Social media and a camera in everyone’s pocket democratized news and information sharing AI in everyone’s pocket with the ability to create “real” images that are indistinguishable from reality will…
Not surprised at all. Waymo provides a better experience without another person in the car you don’t know. People will go for the space and privacy of self driving cars for business calls, perception of safety and just piece of mind.
