Courses
-------

*Systems Programming in Linux* is a series of courses, each of about
two or three days worth of content (mixed lecture and exercises).

* :doc:`basics`. A big picture of Linux/UNIX programming is given,
  serving as the basis for all other courses in this series.

  * Shell intro
  * *Everything is a file*
  * Toolchain, and Debugging
  * Core concepts: processes, files and directories, and permissions

     basics

* :doc:`network`. A thorough walkthrough of network programming.

  * Paradigms, and basic system calls (``socket()``, ``connect()``,
    ``bind()``, ``listen()``, ``accept()``)
  * TCP/IP networking: TCP and UDP communication
  * UNIX domain sockets
  * CAN-Bus networking (optional)
  * Async: ``select()``, ``poll()``, and ``epoll()``
