Business debates who benefits most from time. When borrowing money, the debtor gains the benefit of time until the repayment date. Since the period before repayment favors the debtor, the debtor compensates the creditor with interest. However, as the repayment date approaches, time shifts to favor the creditor. After the due date, the debtor loses the benefit of time, known as ‘acceleration of debt,’ and must repay both the principal and interest. Time benefits debtors but poses risks to creditors. Therefore, lending money without interest results in a loss. All of this illustrates the power of time. Time is money, and money derives its value from time. The most important factors for CEOs to focus on are time and, next, opportunity cost. - 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"
