X.Org developer Daniel Stone explains the history and technical limits of the X Window System and why Wayland was created, debunking myths from forum comments. He covers topics such as network transparency and blocking calls.

Rob Landley compares Toybox and BusyBox and surveys options for embedded system command-line tools, including GNU. He also tells the story of leaving BusyBox, Toybox becoming Android's command line, and licensing.

Rusty Russell and Matt Evans examine why Unix utilities like ls and cat grew from a few kilobytes to over a hundred kilobytes. They take apart common tools to see where the growth comes from.
