I am planning to focus on Go and developing a deep understanding of computer networking. I think with cloud, IOT, increasing importance of cybersecurity, understanding the nitty gritty of networks is going to be increasingly important.
Off topic, but Beej's Guide is how I want my ebooks formatted. I wish other publishers would take note. Safaribooks, Packt, Manning, Amazon - their ebook formats all suck. Just use HTML with a little syntax highlighting, that's all it takes. https://beej.us/guide/bgnet/html/#bind
I'd recommend reading the "classical" RFCs for TCP, including 1122 ("Requirements for Internet Hosts", https://tools.ietf.org/html/rfc1122 ).
Learning the basics of Ethernet would be helpful as well and is one of those foundational skills that'll make it easier to understand various protocols, commands in Linux, etc.
I have been working through the Kurose + Ross textbook, and will be trying to implement some of the concepts/exercises in the book in Go. I've also been reading through the networking sections of the Unix + Linux System Administrators Handbook
