Two of our attendees were refused a visa 😞
Still, that means we have two tickets left if anyone wants to come at this late stage.

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…
I hope someone can explain the importance of Adobe products in modern lesbianist lifestyles.

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.
