Not sure why but this site is being detected as a malware by our CORP detection system "This site is blocked due to a security threat."

Thanks for the heads up. I wonder what it's hitting on. There's no 3rd party anything. There's not even any javascript.

do you plan on allowing people to make translations? if so, maybe putting it on github would be easiest?

That's not a bad idea. Its already on GitHub (I showed my wife how to use git because she's doing the proofreading), so it would just require me making it public.

Which is awfully suspicious on today's modern web.

I feel like walkie talkies are something all network engineers need to play with. Furthermore, remember that real world telephone and radio networks were in fact... Networks. (Called 'nets' in the radio world) Ethernet, and 802.11, are both based on the concept of a singular channel shared by many individuals. When Alice talks, she says 'I'm Alice calling Bob, can you hear me Over'. Alice is the source address. Bob i…

> Dave knows to stay off the channel (otherwise he will cause interference)

What would be the Bob-Alice-Dave equivalent to replacing the network hub with a switch?

If you wanted to add a learning switch to the example, you'd also need to add the concept of multiple channels. Once a switch learns which channel the recipient is on, it would only send to that channel instead of broadcasting to everyone. It still starts to break down unless you torture the analogy a bit more.

Early in my career, i had come across the classic Internet System Handbook by Marshall Rose and Daniel Lynch which gives an overview of the Internet and its Protocols circa early 1990s. It is still relevant for the basics.

I wish somebody would write something like the above for the "Modern" Internet.
