Debt inevitably incurs costs: the interest and the usage fee. Borrowing means using someone else’s property as if it were my own. When the purpose of borrowing is achieved, or when the agreed time to return it arrives, it is returned to another person’s possession, and the borrowing cost is no longer incurred. Costs also serve as the basis for production and are the consideration for almost all debts, regardless of the borrowing purpose. The frightening aspect of debt is that it incurs costs and requires repayment of the principal. Originally, the principal was not mine. Thus, spending with other people’s money exposes you to significant risks, especially when you spend on perishable consumption that disappears after use. If you spend someone else’s money without differentiating between production costs and costs for extinction, you are on the fastest path to destruction. Therefore, luxury can ruin even the rich. - 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"
