This is some example code showing how to use the ptrace system call under Linux to trace the system calls of a child process.
/*
ptr_inspect.c
Demonstration code; shows how to trace the system calls in a child
process with ptrace. Only works on 64-bit x86 Linux for now, I'm
afraid. (Even worse, it's only tested on Linux 2.6....)
The callname() function looks clunky and machine-generated because it
*is* clunky and machine-generated.

True Colour (16 million colours) support in various terminal applications and terminals

Terminal Colors

There exists common confusion about terminal colors. This is what we have right now:

  • Plain ASCII
  • ANSI escape codes: 16 color codes with bold/italic and background
  • 256 color palette: 216 colors + 16 ANSI + 24 gray (colors are 24-bit)
  • 24-bit true color: "888" colors (aka 16 milion)
