Small Fun: Although not essential, small fun helps prevent corruption and depravity, and keeps greed in check. In fact, the key to controlling greed isn’t moderation, but small fun itself. However, if that small fun ever disappears—leaving you bored or unmotivated—it’s important to take time for self-reflection. While big fun doesn’t last long and can actually fuel greed, by contrast, small fun supports steady effort and offers you time to reflect leisurely. Therefore, to live a happy life, we must find some small fun. - 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"
