“I can live well alone!” is not correct. If I live alone, I can survive to some extent, but ultimately, it is hard to survive, and “living well” is even more challenging. This is because the economic principle is established not by ‘alone’ but by ‘many people.’ If I live well, it means that someone has become poor because of me or is living well with me. The fact that through value exchange, or transaction, we can meet each other’s needs and store the surplus from that production is both true and real. Trading is not done in isolation. - 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"
