Poison: Writer Jong-bong Kim , a full-time investor, said in his book “ Money Scenario ,” “All profits you get without knowing it are poison.” If you make money without knowing whether it’s from a business or a stock investment , you operate and invest with that unaware mindset. Acting without explicit knowledge is extremely risky. The more money you earn unknowingly, the faster a significant loss will come. Continuously doing your business without understanding why customers buy your products or why your stocks generate profit can lead to a serious crisis. The greater the influence, the larger the impact. Whatever you do, you need to understand the core and operate properly. Don’t let luck alone control your abilities. The odds of winning the lottery don’t happen every day. Don’t waste time on gambling. The difference between gambling and business, and between investing and gambling, is just a single page of paper. - 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"
