Rolling Code Vs. Fixed Code RF Remote Control
Remotes control send signals in code. When the sending code is the same as the code which is expected by the receiver, the relay will switch and the door, barrier or car will open. Remote controls with a fixed code will always send out the same code. A rolling code (or hopping code) always send out a different code from the one previously sent. The code changes every time because of the algorithm which is part of the remote control.

“This whole moment is the groin
Of a borborygmic giant who even now
Is rolling over on us in his sleep.”
—John Ashbery (b. 1927)
“Many people will say to working mothers, in effect, “I don’t think you can have it all.” The phrase for “have it all” is code for “have your cake and eat it too.” What these people really mean is that achievement in the workplace has always come at a price—usually a significant personal price; conversely, women who stayed home with their children were seen as having sacrificed a great deal of their own ambition for their families.”
—Anne C. Weisberg (20th century)
“The nation looked upon him as a deserter, and he shrunk into insignificancy and an earldom.... He was fixed in the house of lords, that hospital of incurables, and his retreat to popularity was cut off; for the confidence of the public, when once great and once lost, is never to be regained.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
“Oh! what a poor thing is human life in its best enjoyments!—subjected to imaginary evils when it has no real ones to disturb it! and that can be made as effectually unhappy by its apprehensions of remote contingencies as if it was struggling with the pains of a present distress!”
—Samuel Richardson (1689–1761)
“If someone does something we disapprove of, we regard him as bad if we believe we can deter him from persisting in his conduct, but we regard him as mad if we believe we cannot. In either case, the crucial issue is our control of the other: the more we lose control over him, and the more he assumes control over himself, the more, in case of conflict, we are likely to consider him mad rather than just bad.”
—Thomas Szasz (b. 1920)
