Murphy's Computer Laws As soon as you delete a worthless file, you'll need it. Installing a new program will always screw up at least one old one. The first place to look for a lost file is the last place you would expect to find it. Any sufficiently advanced technology is indistinguishable from magic. Important lettes that contain no errors will develop errors on the way to the printer. Regardless of the program, you won't have enough hard disk space to install it. The easier it is to get into a program, the harder it will be to get out. Every machine will eventually fall apart. In a computer manual, any simple idea will be worded in the most complicated way. If you hit two keys on the keyboard simultaneously, the one that you don't want will appear on the screen. The probability of anything going wrong is in inverse proportion to the desirability. No matter how long you shop for an item, after you've bought it, it will be on sale cheaper the next day. The computer only crashes when printing a document you haven't saved. If you make a copy of your system configuration nine out of ten times, the tenth time is the only time you'll need it. The more pounds the package weighs, the harder it will be to find the installation instructions. The need for space on a disk will always exceed the available space by ten percent. The likelihood of a hard disk crash is in direct propportion to the value of the material that hasn't been backed up. There are only two kinds of computer users: Those whose hard disks have crashed, and those whose hard disks haven't crashed - yet. Before you do something, you will need to do something else first. Anything can be made to work if you fiddle with it. If you fiddle with something long enough, you'll break it. If at first you don't succeed, try again. Then quit. No use being a fool about it. You can't win them all, but you can sure lose them all. Don't let any mechanical device know that you're in a hurry. If it's worth doing, it's worth hiring someone who knows how to do it. The one piece of data you're absolutely sure is correct, isn't. Never put off till tomorrow what you avoid altogether. The writer will find the typos after the letter is mailed.
