Originally discovered by technicians on crash tests at Cailfornia in 1949, Murphy's Laws spread quickly. They were spotted everywhere: buses always came in threes, desperately needed objects became invisible, etc...

Well, let us post them over here..

These are some of my favorite picks among the Murphy's Laws regarding software/technology. I've taken them from 'Why the toast always lands the butter side down' by Richard Robinson.

1) "If it's not in the computer, it does not exist."

2) "Whenever a system becomes completaly defined, some damn fool discovers something which either abolishes the system or expands it beyond recognition."

3) "Nothing ever gets built on schedule or within budget. Or, all is well that ends."

4) "If there is the possibility of several things going wrong, then the one that will cause the most damage will be the one to go wrong."

But why make you suffer more?! Should not make it lengthy for Murphy also says, "The longer you look at a page, the more the words don't get in." ;) ;)

Oops, I misspelt the thread title.

I'd say some of his observations sound pessimistic (sometimes even wierd); but they are surprisingly realistic.

I'd say some of his observations sound pessimistic (sometimes even wierd); but they are surprisingly realistic.

I apologize. Perhaps the spacing I used made it difficult to recognize the context I was giving.

The phrase 'Murphy was an optimist' is the 'law' called O'Toole's Commentary. As you yourself pointed out, the hypothetical original Murphy would seem to have been somewhat, if not severely, pessimistic. So how pessimistic must O'Toole's outlook have been?

How 'bout the 3 laws of thermodynamics re-phrased:
1) You can't win
2) You can't break even
3) You can't get out of the game.

I guess that would be pessmistic beyond the realms of reality.

Capitalism is based on the false assumption you can win (but government prevents that)

Socialism is based on the false assumption that you can break even.

Mysticism and Transcendental Meditation are based on the false assumption that you can quit the game.

Nice collection of laws!

Who the heck was Murphy? Sounds like a massive Pessimist...

Murphy's Law: Whatever can go wrong, will.

0

Edward Aloysius Murphy was an American aerospace engineer who worked on safety-critical systems (1918 – 1990). "Whatever can go wrong, will!" was his first law.

0

Actually, his THIRD law is "If anything can go wrong, it will."

He was a naval officer in World War II when he created his laws.
