The more cordial the buyer's secretary, the greater the odds that the competition already has the order. In designing any type of construction, no overall dimension can be totalled correctly after 4:30 p.m. on Friday. The correct total will become self-evident at 8:15 a.m. on Monday. Fill what's empty. Empty what's full. And scratch where it itches. All things are possible except skiing through a revolving door. And there's probably someone somewhere who managed to do just that. The only perfect science is hind-sight. Work smarder and not harder and be careful of yor speling. If it's not in the computer, it doesn't exist. If an experiment works, something has gone wrong. When all else fails, read the instructions. Everything that goes up must come down. Any instrument when dropped will roll into the least accessible corner. Any simple theory will be worded in the most complicated way. Build a system that even a fool can use and only a fool will want to use it. The degree of technical competence is inversely proportional to the level of management. Any attempt to print Murphy's laws will jam the printer. If you have to ask, you're not entitled to know. If you don't like the answer, you shouldn't have asked the question. -- I am using the free version of SPAMfighter for private users. It has removed 1526 spam emails to date.
