Book Description:

Do you know how your web server opens a socket, binds to an address, and accepts a connection? I did a lot of web programming before I had enough knowledge to dig in and figure this stuff out. I knew that other developers had a better grasp on the full stack than I did, but diving deep under the hood is one of the things that really made me a better developer all around. I recently read a great thread that asked, What did the really successful programmers do differently? This response really caught my eye: Be ready, willing, and able to deep dive multiple levels at any time. You must know what is going on under the hood. There is a strong correlation between, number of levels of deepness understood and programming prowess. In this book I will teach you these fundamentals using Ruby. I will start with the fundamentals that are portable to any environment. Then I will show you the beautiful abstractions that Ruby has layered on top of them. Learning this stuff does not just apply to Ruby, or any other language. Every modern programming language has support for networking. Every language has their own way of doing things. But all modern languages support the Berkeley Sockets API. Ruby is no exception. There is certainly plenty of syntactic sugar, but below the sugar you can use the same Sockets API that you would in C, Java, Python, whatever. This is portable knowledge that will serve you for many years to come.

What you will learn: The steps in the lifecycle of servers and clients. The various ways that we can read and write data in Ruby, and when they are appropriate. All the things you were never quite sure about: EOF, listen queues, TCPNODELAY, and tons more. The low level methods required for constructing sockets, as well as the syntactic sugar that Ruby provides. Known methods that will help you improve socket performance. Basics of SSL sockets. Should you write a lot of data at once or chunk it into smaller writes? Get comfortable with the socket programming API that is available in any modern programming language. More example code than you shake a stick at! A look at 6 different architecture patterns for building concurrency into your network programs. A closer look at a few different protocols: FTP and Redis. Multiplexing connections, non-blocking IO, socket timeouts, socket options, and more.
