Salary isn’t just ‘my money.’ It’s money that should be spent considering yourself today, your future self in 10 years, and your future self in 20 years—that is, your future self together. Therefore, my current income is always, in a way, public money. We need to get approval from our future self before spending now. A bright future is only guaranteed if the future self agrees to the spending. It’s inconvenient to spend other people’s money on your own terms, and thinking of your own money the same way you see others’ cherished money will help you develop good habits for the future. I don’t have an exclusive claim to my own money, as if there’s no such thing as my own air in this world. - 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"
