   i knew i had gotten to a certain level of network backbone engineering when i would consult, discuss some design, and ask "what happens if..." and see a room full of younger engineers look in horror. ;)

     @paul_ipv6 Yep! "I have seen things..." 😀

     Last night he was asking how he could definitively determine he was calling APIs only on localhost (making sure he hits the local emulator, not the cloud). And he starts explaining how he will use dev tools to look at the URLs the XHR requests are connecting to and so on. I said "you could do that. Or you could just turn your wifi off."

     😀

     If you know the "knowing where to tap" story, I have a fun story to show you how this old guy knew where to tap.

     My (college age) son is working on developing a web site. React, Google CloudRun functions, the whole bit. Twice he came to me today (because I was working from home) and he's super frustrated. He is getting an error and he doesn't know what to do. He reads the error out to me and says "https". I say "hold on. You're connecting to your emulator on localhost. It's just http." He does that and it works.

     Three hours later, he comes back with another mindbending error. I take one look at his code and say "See where you have port 5053? That needs to be 5051". He changes that. and it works.

     So twice I fixed his problem by recommending a single letter change. There is no better example of "knowing where to tap." And since my son is smarter than me at programming, I have to celebrate my little victories where I can.
