Demystifying Non-Blocking and Asynchronous I/O (#164)

Description

Demystifying non-blocking and asynchronous I/O

Presented by Peter A Portante

We will first define what blocking, non-blocking, synchronous and asynchronous I/O are under the POSIX interfaces. We'll cover how and when these four types of I/O should be used, and their individual effects on a Python based application. The notion of concurrency will be discussed by comparing a simple threaded blocking I/O application to a simple single threaded non-blocking I/O application by walking the attendees through the python code for those applications.
