Copying the masters is a traditional part of an artist’s practice for a reason! Your copy will almost always be terrible, relatively speaking, and you also learn a lot by trying.

My dad abhors any negative comments about immigrants. Asked him recently why he’s so strong on it: β€˜Because we’re always happy to take the rich and clever ones. Which means it’s not about disliking immigrants. It’s about disliking the poor and vulnerable. And that’s a bad human instinct.’

Yes! Stephen Sprouse et alii. Somehow black and brights is too high-contrast for me (I can’t do black and white either, only black + dark grey + very occasionally other low-saturation colors, like aubergine.)

The church next to me in Central Sq was incredibly bad at clearing their walk, and so many people just *struggled* to get past (including me with my groceries, but obviously especially people with strollers, walkers etc.) β€” it is such a fuck-you to (a profound lapse in care for) your neighbours.

You are 100% correct.

Grey + brights = infrastructural palette.

Black + brights = hazard signage.

I mentioned to a Vancouver local that I'd already bought a snow shovel and some ice melt, because of course you don't want to be getting them *after* it snows, and apparently I'm a bit more serious about clearing the sidewalk than the local norms.

I've talked about the events of that day with my US engineering faculty colleagues and my students many times over the years -- it's almost always the first they've heard of it.

On its 36th anniversary, it was in the brief top-of-the-hour news on CBC Radio this morning. I teared up hearing it.

Extralibrary Loan: Making the Civic Infrastructure We Need Amid a war on public knowledge, libraries are pushing outward, enlarging the commons through new configurations of civic and creative life.

"The library is not meant to be a node in the just-in-time-economy that puts a rights-restricted copy of 'Abundance' in our AirPods. It’s meant to be an accessible portal to our government, the place we go to access shared knowledge and to make meaning with others."

A rough stucco box with a wall and another box. There's a yellow Porssche in front. It probably hasn't even chimed 1970 yet.

A rough stucco box with a wall and another box. There's a yellow Porssche in front. It probably hasn't even chimed 1970 yet.

Quote from "Gehry Talks" in an article on gehry by the great Jean-Louis Cohen: Gehry has described the process: β€œWhatever was in my consciousness, I loved raw rough stucco. No buildings were being done with that. They call it β€˜tunnel mix.’ It was underneath the freeways. Under the freeways they’d spray it on. So I asked the plastering contractor to do it, and they said they couldn’t; they didn’t know how. An artist friend was building a little studio in Venice. I told him what I was looking for. He said it sounded great, and if I wanted to use his garage to experiment on, he wouldn’t mind. I found out what the equipment for tunnel mix was. I went to the U-Haul and rented it, mixed the plaster, and did it myself. I sprayed it on the garage, and it was beautiful! Then I brought the contractor down, showed him the equipment, showed him the walls, and that’s how the Danziger building was made.”

Passengers are stressed, angry, and frustrated *at the airlines*. Flight attendants (and desk staff) are who get stuck dealing with it. And yes, you sure as hell should be kind to them.

Requiring airlines to pay compensation is the equivalent of yelling at the people who are actually responsible.

I got a US$500 cheque because my AA flight out of Boston was delayed for operational reasons, and I was flying to Canada.

The current administration just rolled back a similar requirement to compensate US passengers.

But sure, slippers.

It seems like the deformation professionelle of economics is particularly strong because money has become such a universal metric -- like putting a dollar value on human lives! -- so seeing everything through that lens is easy, useful to capitalism, and often not even noticed as a specific lens.

Loved this 🧡 from the NY Transit Museum, in honor of Rosa Parks' anniversary today, about the desegregation of the NYC transit system. In 1854! By a teacher!

Side note: When my son was little, NY Transit Museum was one of our favorite spots. It's a gem of a local museum for kids and adults alike.

When I lived in London, I enjoyed telling people that I was from Canada but it was the furthest north I’d ever lived. [I grew up at 44N, and just moved from Boston (42N) to Vancouver (49N). London is at 51N, and Edinburgh and Glasgow are at about 55N β€” north of Edmonton, south of most of Scotland.]
