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"

Results

These are instructions for booting from an Ubuntu liveCD and installing NixOS on a machine. I needed to do this because the NixOS liveCD doesn't work on my machine (NixOS/nixpkgs#5829), so I'm just using the Ubuntu installation media as something to boot into.

Much of this is from discussion at NixOS/nixpkgs#14680.

Get the Ubuntu ISO: http://releases.ubuntu.com/16.04.1/ubuntu-16.04.1-desktop-amd64.iso

Write it to a USB drive with unetbootin

	# Start the old vagrant
	$ vagrant init centos-6.3
	$ vagrant up

	# You should see a message like:
	# [default] The guest additions on this VM do not match the install version of
	# VirtualBox! This may cause things such as forwarded ports, shared
	# folders, and more to not work properly. If any of those things fail on
	# this machine, please update the guest additions and repackage the
	# box.
