My Comments: Here is Murphy’s Laws Part Two. This is the second of six such lists that I’m sharing with everyone. As a reminder, they’re not in alphabetical order so do with then what you please.

-Etorre’s Observation:   The other line moves faster.

-First Law of Revision:   Information necessitating a change of design will be conveyed to the designer after – and only after – the plans are complete.   (Often called the ‘Now They Tell Us’ Law)

-Second Law of Revision:   The more innocuous the modification appears to be, the further its influence will extend and the more plans will have to be redrawn.

-Corollary to the First Law of Revision:   In simple cases, presenting one obvious right way versus one obvious wrong way, it is often wiser to choose the wrong way, so as to expedite subsequent revision.

-LAWS OF COMPUTER PROGRAMMING: I.  Any given program, when running, is obsolete.

-LAWS OF COMPUTER PROGRAMMING: II. Any given program costs more and takes longer.

-LAWS OF COMPUTER PROGRAMMING: III. If a program is useful, it will have to be changed.

-LAWS OF COMPUTER PROGRAMMING: IV. If a program is useless, it will have to be documented.

-LAWS OF COMPUTER PROGRAMMING: V. Any program will expand to fill available memory.

-LAWS OF COMPUTER PROGRAMMING: VI. The value of a program is proportional to the weight of its output.

-LAWS OF COMPUTER PROGRAMMING: VII. Program complexity grows until it exceeds the capabilities of the programmer who must maintain it.

-LAWS OF COMPUTER PROGRAMMING: VIII. Any non-trivial program contains at least one bug.

-LAWS OF COMPUTER PROGRAMMING: IX. Undetectable errors are infinite in variety, in contrast to detectable errors, which by definition are limited.

-LAWS OF COMPUTER PROGRAMMING: X. Adding manpower to a late software project makes it later.

 -Lubarsky’s Law of Cybernetic Entomology:   There’s always one more bug.

-Shaw’s Principle:   Build a system that even a fool can use, and only a fool will want to use it.

-Law of the Perversity of Nature:   You cannot successfully determine beforehand which side of the bread to butter.

-Law of Selective Gravity:   An object will fall so as to do the most damage. 

– Jennings Corollary to the Law of Selective Gravity:   The chance of the bread falling with the butter side down is directly proportional to the value of the carpet.

-Wyszkowski’s Second Law:   Anything can be made to work if you fiddle with it long enough.

-Sattinger’s Law   It works better if you plug it in.

-Lowery’s Law:   If it jams – force it.   If it breaks, it needed replacing anyway. 

-Schmidt’s Law:   If you mess with a thing long enough, it’ll break.

-Anthony’s Law of Force   Don’t force it – get a bigger hammer.

-Cahn’s Axiom:   When all else fails, read the instructions.

-Gordon’s First Law:   If a project is not worth doing at all, it’s not worth doing well.

-Law of Research:   Enough research will tend to support your theory.

-Maier’s Law:   If the facts do not conform to the theory, they must be disposed of.

-Peer’s Law:   The solution to the problem changes the problem.
