Time Preference Rate. “The Marshmallow Tale” by Joachim de Posada and Ellen Singer describes the “Marshmallow Experiment” at Stanford University. The experimenter left the child alone in the room and gave the child a marshmallow, instructing the child to eat it immediately. However, if the child did not eat it within 15 minutes, the experimenter would give the child another marshmallow. Some children waited the full 15 minutes, while others stopped waiting early. These two groups were followed for 14 years, and as a result, the more patient children showed better social and mental abilities. Those who cannot tolerate waiting are said to have a high time preference rate, while those who are patient are described as having a low time preference rate. In investment, high and low time preference ratios are not necessarily good or bad because many investments depend on luck. The key is to find and stick to methods and principles that match one’s own tendencies. - 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"
