"Unfortunately, switching regulators are also one of the most difficult linear circuits to design. Mysterious modes,
sudden, seemingly inexplicable failures, peculiar regulation characteristics and just plain explosions are common occurrences. Diodes conduct the wrong way. Things get hot that shouldn’t. Capacitors act like resistors, fuses
don’t blow and transistors do. The output is at ground, and the ground terminal shows volts of noise.

rlwrap – Freecode

rlwrap is a readline wrapper, a small utility that uses the GNU readline library to allow the editing of keyboard input for any other command. It maintains a separate input history for each command, and can TAB-expand words using all previously seen words and/or a user-specified file.
