Git Cheat Sheet

Create an empty git repo or reinitialize an existing one

$ git init

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"

	"""
	Install twisted (pip install twisted) and PIL (pip install PIL), and run the script.

	On your gateway, run the following commands:
	iptables -t nat -A PREROUTING -i br0 -s ! 192.168.0.20 -p tcp --dport 80 -j DNAT --to 192.168.0.20:8080
	iptables -t nat -A POSTROUTING -o br0 -s 192.168.0.0/24 -d 192.168.0.20 -j SNAT --to 192.168.0.1
	iptables -A FORWARD -s 192.168.0.0/24 -d 192.168.0.20 -i br0 -o br0 -p tcp --dport 8080 -j ACCEPT

	Substitute 192.168.0.20 for the computer running the proxy.
