The relativity of values causes us to use money irrationally. I go to the supermarket to buy a $15 pen, and the clerk smiles and says, “You can buy this pen for $7 if you walk 5 minutes from here.” Then, most people walk five minutes and buy a $15 pen for $7. But if you want to buy a $1,000 jacket and the clerk smiles and says, “You can get a $992 jacket in five minutes from here,” most people simply buy the $1,000 jacket. Reasonably, walking for 5 minutes equals the effort, and the profit of $8 is the same. However, people might go to a store that sells pens cheaper, but not for the jacket, because the discount rate is too low. In other words, the relativity of comparing values makes us act irrationally. The pen’s discount rate is 55%, and the jacket’s is only 0.8%. Yet, the total amount is the same for all $8, and the effort to gain that profit is identical. Attitudes and misconceptions about consumption influence how we build wealth. - Joseph’s “just my thoughts”
For the security of the Internet service, we have been asked by the Internet service companies to set the password combined by more than 8 or 10 "uppercase letter+lowercase letter+number+special character". But it was obviously of no use. This security guideline was recommended by Bill Burr who worked at NIST in the USA, he suggested this way in his report. Furthermore, the user was required to change the initial password set regularly. Despite this measure, the best way of security to protect users' accounts was the notification of the alarm for attempted hacking when the hacker tried. We have only tried to change the keys despite the simple method meanwhile. Today, the world has begun to comprehend that the security problem is not encryption or confidentiality, but simply cyber-dominion control and communication. - Joseph's "just my thoughts"
