I am hosting a live show a few times a month about internet infrastructure and today's topics were, your favorite 
questions asked network engineers - you can watch the recording here

if you have suggestions on topics to cover helping network operations engineering that you want to see in here, 
please feel free to contact me off-list, and let's create unique content that can be helpful to others.

"What happens when you type www.google.com in your browser bar and hit
enter?" is one of my favorite questions. Half the field of computing
happens next. Keyboard interrupts fire. Bits are poked in dram, sram,
maybe even tcam. Packets are sent. Fonts are composed into pixels.
There's a crazy amount you can talk about and the right answer is:
string things together in order for 5 or 10 minutes without getting
anything horribly wrong.

Oh, I thought this was a trick question of whether it takes you directly
to google, or does a search.

That's a good start. First thing the browser does decide whether
that's a URL or a search question. How does it decide? And then what
happens?

I will prompt you to keep talking. After all, I'm rooting for you to
succeed so that I can hire you.
