The PercolationVisualizer class from Coursera's Algorithms I course, modified for text-only output. It uses ANSI escape codes for colors and screen clearing. Laggy demo: http://www.playterm.org/r/MjAxMy0wOC90dHlyZWNvcmQtMTM3NzU1MDgyNXw4MHgyNA==
/****************************************************************************
* Compilation: javac PercolationVisualizer.java
* Execution: java PercolationVisualizer input.txt
* Dependencies: Percolation.java StdDraw.java In.java
*
* This program takes the name of a file as a command-line argument.
* From that file, it

Setup script for Coursera's Algorithms I class. Downloads the relevant files and massages them into a /path/to/class/{bin,lib} structure.
#!/bin/bash
# Load class materials for Coursera's 'Algorithms I' course into the directory
# specified on the command line. Files will be downloaded directly from the
# class book site, maven and ellotheth's Makefile samples. Where appropriate,
# hard-coded paths (in e.g. source files and shell scripts) will be replaced
# by the user-specified path.
#
# USAGE
# $ chmod +x algo-i-setup.sh

Mockable interface methods in Go, maybe
type InterfaceThing interface {
MockableMethod() int
TalksToMockableMethod() bool
}
func MockableMethod() int {
// i do things that are annoying to test, like run exec.Cmd or talk to a database!
return 0
