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

CARNEY: “.. You cannot live within the lie of mutual benefit through integration when integration becomes the source of your subordination.” 🔥
Carney: "American hegemony in particular helped provide public goods, a stable financial system... this bargain no longer works. Let me be direct.

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.
A YouTube link for those looking for it. No words.

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"

2025 is coming to end and some people who claim not to be fascists are still associating themselves with fascist outlets like X.

DNS over QUIC sounds good:
