It’s weird that people online treat politics like sports, yet never learn the part where you’re allowed to be mad at your own team for blowing it.

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...

Seems to me that you can discourage driving to the games by setting parking fees north of $1000 per hour* and then making transit free.

Maybe add bicycle valet parking for the cost of a food bank donation.

* With accessible parking exceptions, of course

One of the perks of summer camping is getting to sit in a camp chair with a beer and watch the stars come out.

Except daylight savings in Alberta means that in July you've got to stay up until midnight to do this, and I'm too old to stay up that late any more

Would love year round standard time. I hate when we go camping in the summer, and even at 11 pm it isn't dark enough to see stars

A few years ago, my mom dug up some historically significant patents, property details, etc. from her grandparents' rural Arkansas property.

She asked the local archive if they were interested; they were, but only because our family is white. They'd been instructed not to accept records from POC.

Look, I spent half my life farming and using trucks as tools. I can say with certainty that this truck is not used for work, but to only haul a massive, toxic ego, nothing more. These should be taxed out of the driveways of regular commuters.

I went through and added up the total paid rents through our adopt-a-rent program, and it is 329 families for $463,217. All peer-to-peer, no fundraising. Just neighbors helping each other out.

If you want to adopt a family, and can afford to give $500 or more, signal me at asiniiwiikwe.72

These are “low enrollment” majors but the classes are regularly at capacity. They changed the funding structure a few years ago here, switching the allocation from course enrollments to majors then blamed these departments for a structural, top-down change. This is entirely a political choice.

If you spend time in the bad place, you’re hearing this claim a lot:

Alberta sends $23B more to Ottawa than it gets back. If we separated, we’d erase the $9B deficit and have a $14B surplus.

It sounds simple. It’s wrong. Here's why. 🧵

ANALYSIS | Danielle Smith says court 'skewed' to Liberal donors, but UCP picks have political ties just as often | CBC News CBC analysis suggests about one-fifth of federally named judges match with Liberal donor lists. About as many judges picked by the province likely gave to UCP.

When Danielle Smith claimed 80% of federally picked judges had donated to Liberals, that was way higher than any figure I'd researched.
I dug into it. Could confidently write here:
"It is not true. The single media source Smith got that fact from has since corrected it."
