This is really big news. Google introduced the Open Knowledge Format (OKF) - a standardized way to store information in a directory of markdown files. Makes it really easy to make a digital brain that agents can use. These files can serve as a living wiki. You can give agents the ability to query them or edit them. They can interlink. Seems to me this could replace Notion or Obsidian. I can think of so many uses for this. Google's blog post: cloud.google.com/blog/produc… An easier to understand explanation is the SPEC.md file: github.com/GoogleCloudPlatfo… I gave those two links to Antigravity and asked how we could use it for any of the projects we're working on. It came up with so many ideas. I would imagine Claude Fable 5 would whip up some pretty amazing things based on this system. Currently creating an OKF library of our pepper garden. It's going to be a fun weekend.

Could be way off here, but I think ChatGPT is going to make moves to send more and more traffic to websites - because if marketers can prove the traffic is high value it will unlock budget for ads. Also, I have NEVER met a marketer that trusts view through conversions.

Now we know why Peter Thiel packed his bags for Argentina. Milei just submitted his AI legislative framework to Congress, where he proposes: - zero regulation on AI development, - a brand-new "non-human corporation" category for AI/robot-operated entities with limited liability -a low-tax regime with flexible governance rules. The Dutch East India Company gave the world the limited liability company in 1602. Milei wants Argentina to do the same for autonomous AI agents in 2026.

The European Parliament has decided to say goodbye to Google. Internal computers will now run the European Qwant search engine by default. Sovereignty is non-negotiable! 🇪🇺

WordPress lightbulb moment. HTML-in-canvas is an elegant answer to @photomatt's push for 'weird themes' - they'll enable innovative/creative/unconventional etc UI on top of conventional surfaces, and even degrade gracefully.

MICROSOFT OPEN-SOURCED A GOVERNANCE LAYER FOR YOUR AI AGENTS and it's exactly what agentic ai has been missing here's what agent governance toolkit does: ▫️ intercepts every tool call in deterministic code before it hits the wire denied actions aren't unlikely, they're structurally impossible ▫️ yaml policy engine lets you allow, deny, or require human approval per action ▫️ zero-trust identity via spiffe/did/mtls no more 5 agents sharing one api key ▫️ 4-level execution sandbox with privilege rings so agents can't escape their scope ▫️ tamper-evident merkle audit logs for compliance and incident response ▫️ covers all 10/10 owasp agentic top 10 risks ▫️ works with langchain, crewai, autogen, openai agents sdk, semantic kernel, and more one pip install...any framework...python, typescript, go, rust, .net all supported because "please follow the rules" in a system prompt is not a guardrail...it's a suggestion github.com/microsoft/agent-g…
