jeffeb3 / .Xmodmap
Created January 29, 2016 00:08
Xmodmap for mimicking pok3r keyboard layer.
! Trying to F*** with my keyboard.
!
! The theory is that if I make the caps lock be the "Mode_switch" key,
! then I can change what happens for each key when I press the "Mode_switch" key.
!
! I'm not using the "Mode_switch" key anyway...
!
! This will make the caps lock be the "Mode_switch" key.

Simple functions to calculate medians from doubles.
#include "median.h"
#include <string.h>
// Storage for the input to the median filter.
double data[MEDIAN_FILTER_SIZE];
double median_data[MEDIAN_FILTER_SIZE];
// Pointer to the next element in the median filter. Not very safe programming!
double* pNextDataInput = data;
