Enter a Password

A woman was helping her husband set up his computer, And at the appropriate point in the process. She told him that he would now need to enter a password, something he could remember easily and will use each time he has to log on.
The husband was in a rather amorous mood and figured he would try for the shock effect to bring this to his wife's attention. So, when the computer asked him to enter his password,
He made it plainly obvious to his wife that he was keying in....
P... E... N.... I... S...
His wife fell off her chair laughing when the computer replied:
***PASSWORD REJECTED. NOT LONG ENOUGH***

Centre-pivot irrigator

In 1952, a U.S. patent for a "Self-Propelled Sprinkling Irrigating Apparatus" was issued to Frank L. Zybach of Strasburg, Colorado (No. 2,604,359). A centre-pivoted pipe supported on a series of water-piston-powered wheels rotates and sprinkles water on the crops.A control system ensures that each wheel advances at the correct rate. This is the now-familiar centre-pivot machine that waters large circles of crops in those areas of a country which have limited rainfall but have a supply of surface or well water. It provides irrigation for large areas of even closely-spaced crops for which irrigation ditches are not practical and wasteful of water, or that would be expensive to supply with full coverage with stationary sprinklers.«[Image: a modern example showing the sprinkler pipe carried above a series of large wheels.]
