I’ve heard this a few times. I’m the opposite, I think I learned it once and never forgot it, it seems impossible. Do you understand regex in terms of a state machine? Draw it out. It’s a very simple language.
I didn't look at the page header, only the domain (.ca.gov) and skimmed the illustrations and was wondering why a Canadian govt body is researching an American university. I didn't know California had its own domain.
I would've bet money if Pakistan starts building a GFW, it would be with china's help but no, they bought equipment for this from an american company called Sandvine.
That's my relation with regex.
