Here’s the Canada-Alberta MOU. It’s worth a read. And it’s fine.

Astonishingly, sea ice still hasn't started to reform over the Barents Sea area yet of the #Arctic. This includes record low conditions around Svalbard as well. It's been a very bad few months across the region.

The trivialization of what happened at The Pulse Nightclub is rather disappointing. Yet ultimately unsurprising.
Kash Patel's personal firing of the Pride flag-displaying employee was always absurd and unconstitutional, so I'm glad David Maltinsky is suing, but, wait.
It was a flag FLOWN BY THE FBI that was given to him BY THE FBI?! Come on.
Complaint: storage.courtlistener.com/recap/gov.us...

![On October 1, 2025, after successfully completing 16 weeks of the FBI Academy's
19-week training program, Maltinsky was handed a letter terminating his employment with the
FBI. The letter was signed by Defendant Patel ("Patel"). In the letter, Patel wrote that he had
"determined that [Maltinsky] exercised poor judgment with an inappropriate display of political signage in [his] work area during [his] previous assignment at the Los Angeles Field Office." In short, Patel fired Maltinsky for displaying a pride flag at his workstation that had been flown by the FBI at the LAFO and then given by the FBI to Maltinsky.
The Defendants' discrimination against Maltinsky for engaging in protected speech
was a clear and brazen violation of federal law and the Constitution.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:36eqtmzysqf7wsslczw4uxcd/bafkreid5rog4gjpv3qeneunmoyqxoesnuxac2srp3u6ppnjdxphfv7jcoe@jpeg)

Matthew Desmond’s “Poverty By America” is factual, for readers, and explains the design of American poverty. It makes good arguments.
For Canadians I’d rec Elsbeth Heaman’s “Tax Order and Good Government” for the roots of the Canadian design.

The danger here is not only data misuse but the erosion of trust. When every digital interaction feels like surveillance, the risk is dulling the authenticity that makes such tools valuable.”
One reason LLMs are so popular is the promise of seemingly private, judgment-free interaction. But once users internalize that their data is being recorded, studied, or reused, it could lead to a shift in how people think, speak, and even feel when using AI, says computer scientist Koustuv Saha.

Dr. Koustuv Saha says if users begin to feel their privacy is compromised, they may stop using AI in the very ways that make it useful.

Great perspective from #CDSM2025: causal inference is 'what-if' analysis. You don’t have to get everything perfect—or how dare you use the c-word. What matters is laying out your assumptions transparently and showing us what happens when they're violated.

Finished Gati’s “Zbig”. Got him in a Grand-Grand Strategy way. I’ve never experienced Bloodlands, I don’t have his intuition, just the fuzzzziest Anglo-Acadian intuition about the value sets that make institutions, reinforce, combine to cause power. Hinterlandish.

According to signaling theory, some signals must be costly just to be costly—that's how you get a separating equilibrium. Think peacocks and their oversized feathers. So even if AI removes one costly signal, it doesn't mean we should stop technological progress — we'll just find new ones.
