Bit twiddler information


In computing, bit twiddler may refer to:

  • A piece of source code that does bit twiddling, which may mean:
    • Doing bit manipulation;
    • Interacting with computer hardware, especially when using a bit-banging technique;
    • Reading or writing binary file formats; or
    • Being unnecessarily complex, perhaps due to premature optimization
  • A programmer who writes bit twiddlers, as described above
  • A hacker, an enthusiast or a programmer with profound understanding of the fundamentals of computer operation
  • A hex editor, a software application that allows the manipulation of binary computer files
