Left picture: the pro-Palestina demonstration last weekend.
Right picture: the anti-immigration demonstration this weekend.

Both on the same place about 1km from my house.

Arrests last weekend: 0.
Arrests this weekend: dozens.

Anyone who works on browsers, or might know of where there might be information on this:

I'm pretty sure that a few years ago I heard that browsers (maybe it was a specific one?) were optimizing custom props declared on the :root, and which didn't change values.

Was this a thing? Is it still true?

In the tram I sat opposite two girls, who did some web design and were clearly about to become a couple. It was very sweet

… and then one girl tried to impress the other by naming Adobe products…

Today I went to the university library for the first time in close to 25 years in order to pick up my library card.

They couldn’t help me because the printer broke down. And tomorrow they’re closed due to the official opening.

It’s like coming home, except with more bureaucracy.

Name as many names as you like.
I'd like to hear about people who aren't that well known yet.

Thanks for the pointers. I'm going to take this very slowly. (I'm a bit ill; I saw this as a sort of puzzle).

Also, is this behaviour described in the grid spec? So far I found nothing, but I haven't looked at the spec in ages.
