I think this N-day research is potentially the biggest story of AI, vulnerability finding, and exploit development. red.anthropic.com/2026/n-day… 1/6

Tracing every usermode call on Windows-on-ARM. Clean install, no breakpoints, no hooks, memory not modified in any way. Virtually undetectable. Purely from hypervisor.

French founders went from 3.5% of my Y Combinator batch to 20% of the latest one. In 2 years. Same country. 70 million people. A 6x jump in the French share in two years. This isn't luck. The French education system produces generalists with brutally strong hard science foundations (maths, physics, engineering) who can drop into any new field and rebuild it from first principles. A growing number of them have understood one thing: if you want to build something big, you come to the US and you build it here. Two things I'd tell anyone French and talented reading this: Apply to YC. Seriously. There is no downside. Worst case you lose an afternoon on the application. Best case it changes your life. And you can always say no. It has never been easier to turn an idea into a real company. That's exactly what I'm building with @NanoCorpHQ : you describe the company you want, and you launch it from a single prompt. The barrier to building used to be technical. Now it's just agency.
Startup School is coming to Paris 🇫🇷 on June 29! Hear from founders like @lxbrun of @amilabs, @oliveur of @datadoghq, @kiwicopple of @supabase, @james406 of @posthog, and more. Join the best builders and hackers from across France and Europe for a day of talks and sessions with YC partners.

OSWatcher has a whole stack on top: GraphQL server, custom Neo4j procedures, extraction plugins.. 🏗️ But the big one is the builder: Recipes that rebuild decades of OS history from scratch and capture it all into the graph, updates included. 🚀That's what I'll focus on next..!

Given access to recent LLMs, the number of things you could be doing explodes. Choosing how to spend your time has never been more important both technically and personally. Building because you can is seductive and it compounds with inexperience. It looks like addiction to me.

Google paid us $57,000 for two bugs in Chrome. We’re not doing this for the bounty, but it’s always fun to get rewarded. These bugs were found using nothing fancier than a $20/month AI subscription. If you’re curious, come check out our talk at the Real World AI Security Conference at Stanford: seclab.stanford.edu/RealWorl… We haven’t published the Chrome bugs in our MAD Bugs series. They work better as part of something even more fun, stay tuned!
