No matter how smart you are, if you don’t exchange values, you’ll starve to death. For one thing, being self-sufficient enables survival, but self-sufficiency is only possible if you have your own assets and can borrow from others. However, even with existing assets, one can only survive through minimal labor and effort, which means engaging in productive activities. Thus, having great intelligence and applying that intelligence to productive activities are two different things. Even if you aren’t brilliant, you can survive if you are productive. It’s essential to identify the productive activities in which I excel and those where I need improvement. If I understand that, I must act without looking back. - 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"
