git diff image files on the command line, with color

This is a simple way to spot check that the modified image in your git index is the image you actually want without having to leave the command line.

Example: http://i.imgur.com/RUenUcM.png

Instructions

  1. Install git, ImageMagick, and jp2a via your favorite package manager.
  2. Put img-ascii-diff somewhere (e.g. ~/bin/img-ascii-diff).
  3. Put attributes in ~/.config/git/attributes.
  4. Modify ~/.gitconfig and add the lines below, pointing to wherever you put img-ascii-diff.

Whiteboard Picture Cleaner - Shell one-liner/script to clean up and beautify photos of whiteboards!

Description

This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.

The script is here:

#!/bin/bash
convert "$1" -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 "$2"

Continuous build on the cheap, using inotify, cmake and a terminal
#!/bin/bash
# Watch paths (given as arguments), automatically build when something changes.
# The script does a couple opinionated things to make my life easier:
#
# * Terminal scrollbuffer is reset before each iteration, simplifying scrolling.
# * I use a filter script to colorize gcc output (clang errors would be nicer).
# * Output is copied to a log file (/tmp/build.log).
# - I open this file in Sublime or vim, which reloads the file on change (each build).
