This project has programming examples to accompany a textbook I'm working on for advanced network programming topics. This text will focus on scalability, reliability, security, and portability. The goal is rather than teaching programmers who to create prototypes that might work, but which fail in the real world, how to finish programs so that they work correctly when exposed to the rigors of the public Internet.
I'm working on this text now (August 2019) and have no clue when I'll be done, but probably at least a year from now.
