Very disturbing implications for a couple of places where I’ve lived, and encouraging ones for the place where I’m from.

From Pew: “We asked people around the world to rate the morality and ethics of others in their country.”

From @vercel.com: An agent performing support duties for a specific customer should receive a tool scoped to that customer's data, not a tool that accepts a customer ID parameter, since that parameter is subject to prompt injection.

GitHub - pydantic/monty: A minimal, secure Python interpreter written in Rust for use by AI A minimal, secure Python interpreter written in Rust for use by AI - pydantic/monty

This is interesting, a 'safe' Python interpreter for use by AI agents. I guess because the LLMs know Python better than Rune or RHAI?

In the last 48 hours, Musk's reactions to the Epstein release show exactly why he bought Twitter.

He's used the platform to call coverage of his emails with Epstein as "lies," elevated his fans who have defended him, and gotten positive reinforcement from his AI chatbot.

At what point does Poilievre look at how Carney handles things and think, crap, I'm really not the person the country needs now?

This is the best speech, just from a pure rhetoric perspective - its sophistication and persuasiveness - that I've seen a politician deliver in a good long while. Really recommend watching or reading the whole thing.

If a restaurant served you a perfectly-cooked steal with a cockroach on it, would your feedback be "It was perfectly cooked, but there was a cockroach on it"?

Or would you just see the cockroach and conclude the steak's inedible?

In case you're wondering what impact bugs have on user feedback.

I've published a post on better prompting for LLMs: "Prompting 101: Show, don't tell"

This is inspired by a similar post from an internal prompt engineering training series I wrote for Mercury:
