Me: Nice! this conference opened the CFP, and I wanted to try this time. I think I may have a strong proposal for it.
*Checks dates*
The conference is during a trip and I won't be able to make it. 😓

Videos should always have the original orientation
(usually landscape). The player should display it with the cropping and positioning needed for the device.
Captions shouldn't be burnt in a video. They should be packaged into a single file with the video, required fonts, animations, and metadata.

Alt: animated gif with a cartoon from The Simpsons showing "old man yells at cloud" written on a newspaper. The old man (Abe Simpson) looks angry and shakes the arm menacingly.

I had to send a correction at work, and was wondering what is a good way to indicate that it is a correction? In Spanish we have "fe de erratas" ("giving faith of mistakes"). Is there a similar thing in English?

View transitions are pretty neat, and I was fortunate enough to write a piece for @piccalil.li about putting them to work.
They're such an exciting new part of the web platform, and I'm elated to see new and boundary-pushing effects making their way into production.
