Most people tend to underestimate themselves excessively. Many say, “Humility is the virtue,” perhaps influenced by social environment and education, but it’s more about recognizing mistakes and limitations than about one’s own potential. That is, self-judgment based on experience. Of course, there will be mistakes and limitations in the future that we haven’t yet encountered, but the possibilities and achievements will be just as numerous. If we assume the odds are about equal, then we shouldn’t need to underrate ourselves. Excessive self-confidence or showiness is a problem, but so is underconfidence. Too much or too little is called arrogance. In Christianity, it’s considered “sin.” - 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"
