Ok, but at the end, for some reason auto-play went straight into John Carpenter's Escape From New York.

I guess it's trying to make up for the initial shitty suggestion?

I remember enjoying the Highlander TV show when I was a kid, and Prime was promoting the movie, so I gave it a shot, and... Ummm....

Big mistake.

This is all so that Ford doesn't have to have separate work and personal phones, isn't it?

If you care about the COVID airborne transmission cover-up
you should read this.

TLDR: there was a COVID airborne transmission cover-up

Would you rather be perceived as likable or competent?

Would you rather be “shrill” but finish your sentence or polite but interrupted by your male colleague?

Would you rather shoot literal botulism into your face or look your real age, you hag?

screenshot of press release from four nations with their logos: Tla’amin Nation; Homalco Nation; K'ómoks Nation; Klahoose Nation.  March 11, 2026
Chiefs from four First Nations communities are urging the public to please approach Aaron Gunn with no caution whatsoever. He is completely harmless, though momentarily unsettled by the alarming possibility that someone might acknowledge the land before a meeting.
Yesterday on social media, the MP appeared to crash out and demand to speak to the manager of land acknowledgements, a position that observers confirm does not exist.
Chiefs whose territories make up the riding had two words for the MP - Chillax, Bud. 
Land acknowledgements have never seized private property, cancelled a mortgage, repossessed a pickup truck, or altered a single title deed anywhere in Canada.
They are simply people recognizing the history of the place where they are standing.
No one is going anywhere. Canada will survive the brief moment of honesty.
Until then, Chiefs across the region continue to reassure the public that land acknowledgements have not, to date, resulted in any land back.
Hegus John Hackett, Tla’amin Nation
Chief Darren Blaney, Homalco Nation
Chief Nicole Rempel, K'ómoks Nation
Chief Kevin Peacey, Klahoose Nation

Maybe the oil execs should drink it to show how safe it is.

"“I don’t care how many times they treat that contaminated water — it’s going to end up here,” said Alice Martin, a Mikisew Cree elder with feathery gray bangs who was pleading with others to help make a plan to fight the oil companies."

Every single campaign that talks about what cyclists must do to be safe, with nary a mention of drivers

Driver: 30km/hr is way too slow for our roads!

Also driver: hey cyclist slow down you’re going 20km/hr - You could kill someone!

This is just what I needed to see today.

E-bikes take cars off the road and that's really important. They also give people freedom, independence, and access to the world without a car.

But they're also fun as hell. And bikes *should* be fun!

"Our province's strong finances are due to our government's responsible stewardship, the unique hard work ethic of Albertans and also an unrelated war."

So funny that the Alberta provincial government introduced its budget about a week and a half ago.

With daylight savings, sunrise today was 8 am, and sunset will be 7:30 pm. Mid day is 1:45 pm.

Even on standard time our mid day was after noon.

It's amazing people will claim "Canada and the USA have the same culture" and then on something as fundamental as "do you trust your fellow citizens to be good" we are further apart than any other two countries

Sorry I'm not more open-minded about LLMs, it's just some fucking maniacs shoveled out a bunch of useless bloatware featuring that technology, did not give me any chance to opt out, reorganized the entire economy around it, zeroed out gains made by green energy, and made it impossible to buy RAM

This is good, but only in a second course that teaches linear independence and basis

I've never taught that formula, partly because I'd like to get away from making math class about memorizing formulas, but mostly because it circumvents learning a process that applies more generally.

Now your students won't be prepared when they need to define a metric on an endomorphism bundle over a manifold!

But is your first course taught to students in their first semester of university?

It's typical in Canada to have a course in first year that does vector geometry, systems, matrix algebra, determinants, and diagonalization.

Sometimes applied linalg in year 2, and proofs in year 3.

Random math teaching question: why do we even teach trace in a first year linear algebra course?

At best it's an example of a linear transformation, but we don't study those until the second course.

It's not like we need it to be able to talk about inner products on operator spaces...
