This page contains various tutorials for getting things done with different software tools. Whenever I need to learn something, I teach myself how to use the new tool, but quickly forget it, unfortunately. From this experience I have learned that it requires less time for me to write a tutorial as I go along the first time, so that the second time I don't have to reinvent the wheel again. I try to make the tutorials informative and helpful so that others can benefit from them as well. Enjoy!

Moodle Virtual-Programming-Lab (VPL)

Tutorial	Comments
Moodle/VPL Server Setup (Python)	This tutorial provides rough directions for setting up two virtual servers that will host Moodle on one of them, and the VPL jail server on the other. This setup is used by the tutorials below on the use of VPL to test student programs.
Moodle VPL Example 1: Hello World! (Python)	This tutorial illustrates how to setup VPL to test a simple Python 3 program that prints the string "Hello World!" to the console.
Moodle VPL Example 2: Min of 3 Numbers (Python)	This tutorial illustrates how to setup VPL to test a simple Python 3 program that receives 3 numbers from the console and prints the smallest of the 3. The program is tested 3 times, with 3 different sets of input numbers.
Moodle VPL Example 3: Rock-Paper-Scissors (Python)	This tutorial shows the settings for a VPL activity that would test a Python program that plays the game of Rock-Paper-Scissors. The program tested is expected to get its input as pairs of letters (PP, RS, PS, etc), indicates the winner of each round, and stops when one player is 3 points above the other.
Moodle VPL Example 4: Gremlins in my File! (Python)	This tutorial illustrates how to setup a VPL activity that tests a student program that reads a text file, modifies it, and stores the new content back in the original file. This requires an additional python program that sets up the environment for the first one to run, provides it the information it needs, and captures its output.
Moodle VPL Example 5: Print a 2D chessboard (Python)	This tutorial illustrates how to setup a VPL activity that tests a student program that asks the user for an integer and then prints a 2D chessboard (alternating black & white cells) with that dimension. The size of a cell is a 3x3 character on the screen.
Tips & Tricks (Python)	A collection of notes, recommendations, tips, tricks, and modifications.
