Why ISP doesn’t know our activities when we use HTTPS?

Noted with thanks. Btw how to change the modem w/o breaking fibre cables?

Thanks and TL;OS (too long only skimmed). May I ask how to summon a summary bot here?

Thank you. Although it may be irrelevant, do we need a VPN to avoid interception (what is it?) even if there is HTTPS?

Sorry for lurking too much…how to use the bot?

Do you mean decision-making on food or generally good decision-making? Not sure on what does it mean by reasonable problem solving, could we have some specific examples? Thank you.

Thanks for your explaination with examples. What is a column vector? Is it something like (1 2 3) which means move x upwards 1 unit, y up 2 units, z up 3 units?
