Louis Rossmann made a video about it noday I think. They (apparently) don't serve 4k in browsers, only if you use their propietary apps and allow to send them all your data

In spanish questions intonation changes occur only on the last word(s), not the whole sentence. I'm not a linguistic, but I think it's so you can be sure a sentence is a question from the start.

When reading english sometimes I assume a sentence is an affirmation until I see the question mark, and then I have to reinterpret the sentence. I wonder how it is for native english speakers. Do they assume nothing until the sentence is finished?

Do they? I remember not long ago I just had to have an ads.js file, and if the user had an adblocker this file wouldn't load.

So I just had a

var ads_enabled = true;

And I could check if the user had an adblock.

I think most people just install ublock/others and leave it default. When I tried to customize ublock all those lists and regex pushed me away, never tried again since.
