Here's a sample from this site:

Murphy's technology laws

• Logic is a systematic method of coming to the wrong conclusion with confidence.
• Whenever a system becomes completely defined, some damn fool discovers something which either abolishes the system or expands it beyond recognition.
• Technology is dominated by those who manage what they do not understand.
• If builders built buildings the way programmers wrote programs, then the first woodpecker that came along would destroy civilization.
