What if someone asked the current Uk Home Secretary, Theresa May, to write a technical book for politicians? Clearly she must know an awful lot about the inner workings of the internet, given how opinionated she is on the matter. (This book is a work of satire. The author is as indicated on the item listing, not in big type on the front cover.)
"The little green book" as issued to all Conservative politicians. I was at a present when a senior tory was laughed out of the room when he got the link layer prefix wrong. He went on to "get brexit done" and party like it was 2021 so probably a lesson to be learnt there.
