Murphy's law in a modern day perspective:
Here are a few examples of Murphy's Laws relative to hardware.
Law of Inconvenient Malfunction: A device will fail at the least opportune possible moment.
Law of Cable Compatibility: If you choose a cable and a connector at random, the probability that they are compatible is equal to zero.
Law of Hardware Compatibility: The probability of a given peripheral being compatible with a PC is inversely proportional to the immediate need for that peripheral.
Law of Bad Sectors: The probability that an untested diskette will have bad sectors is directly proportional to the importance of the data written onto the diskette.
First Law of Selective Gravitation: When an object is dropped, it will fall in such a way as to cause the greatest possible damage to itself and/or other objects on which it lands.
Second Law of Selective Gravitation: The tendency for an object to be dropped is directly proportional to its value.
Law of Reality Change: Unalterable hardware specifications will change as necessary to maximize frustration for personnel affected by said specifications.
Law of Noise: Noise bursts occur so as to cause the most, and/or most serious, errors in data communications, regardless of the actual amount of noise present.
Law of Expectation: Consumer expectations always outpace advances in hardware technology.
Law of the Titanic: If a device cannot malfunction, it will.
Here are a few greatly simplified examples of Murphy's Laws as they relate to programming.
Law of Debugging: The difficulty of debugging software is directly proportional to the number of people who will ultimately use it.
Law of Neurosis: The chances of software being neurotic (developing bugs spontaneously without apparent reason) is directly proportional to the confusion such neurosis can cause.
Law of Available Space: If there are n bytes in a crucial software program, the available space for its convenient storage or loading is equal to n-1 bytes.
First Law of Bad Sectors: The probability of software being mutilated by bad sectors is directly proportional to the value and/or importance of the programs.
Second Law of Bad Sectors: When a program is mutilated by bad sectors, the damage will occur at the point(s) that result in the most frequent and/or severe errors when the program is run.
Law of Noise: When a downloaded program is corrupted by noise, the corruption will occur at the point(s) that result in the most frequent and/or severe errors when the program is run.
Law of Software Compatibility: If two programs are chosen at random, the probability that they are compatible is equal to zero.
Law of Option Preferences: When two people share a computer, their software option preferences will differ in every possible way.
Law of Expectation: Consumer expectations always outpace advances in software technology.
Law of the Titanic: Bug-free software isn't.
