What Are the 48 Laws of Power? The Complete List

1 hours ago

1. Never Outshine the Master: Ensure that those above you always feel superior. Go out of your way to make your bosses look better and feel smarter than anyone else.
2. Never Put too Much Trust in Friends, Learn How to Use Enemies: Keep a close eye on your friends — they get envious and will undermine you. If you co-opt an enemy, he’ll be more loyal than a friend because he’ll try harder to prove himself worthy of your trust.
3. Conceal Your Intentions: Always hide your true intentions. Create a smokescreen. If you keep people off-balance and in the dark, they can’t counter your efforts.
4. Always Say Less than Necessary: Say little and be ambiguous, leaving the meaning to others to interpret. The less you say, the more intimidating and powerful you are.
5. So Much Depends on Reputation — Guard It with Your Life: Nurture and guard your reputation because reputation is integral to power. With a strong reputation, you can influence and intimidate others.
6. Create an Air of Mystery: Be outrageous or create an aura of mystery. Any attention — positive or negative — is better than being ignored. Attention brings you wealth.
7. Get Others to Do the Work for You, but Always Take the Credit: Get others to do your work for you. Use their skill, time, and energy to further your ambitions while taking full credit.
8. Make Other People Come to You — Use Bait if Necessary: Make your opponent come to you. When you force others to act, you’re in control. Bait them, then attack.
9. Win Through Your Actions, Never Through Argument: Demonstrate your point rather than arguing. Arguing rarely changes anyone’s mind, but people believe what they see.
10. Infection: Avoid the Unhappy and Unlucky: Avoid miserable people. The perpetually miserable spread misery like an infection, and they’ll drown you in it.

Using the Power Law Model for Data Analysis in RGA

7 hours ago

1. In the real world, some systems consist of many components. A failure of one critical component would bring down the whole system. After the component is repaired, the system has been repaired. However, because there are many other components still operating with various ages, the system is not put back into a like new condition after the repair of the single component. The repair of a single component is only enough to get the system operational again, which means the system reliability is almost the same as that before it failed. For example, a car is not as good as new after the replacement of a failed water pump. This kind of repair is called minimal repair. Distribution theory does not apply to the failures of a complex system; the intervals between failures of a complex repairable system do not follow the same distribution. Rather, the sequence of failures at the system levels follows a non-homogeneous Poisson process (NHPP). When the system is first put into service, its age...
