At Berkshire Hathaway’s 2013 shareholders’ meeting, Warren Buffett said, “I’ve owned 400 to 500 companies’ stocks in my lifetime, but only about 10 of them made the most money.” His lifelong friend and investment partner, Charlie Munger, added, “With the exception of some of Berkshire Hathaway’s best investment practices, long-term performance is near-average.” Many people know Warren Buffett’s return on investment better than his mistakes or failures. It’s because of those 10 companies that he succeeded in investing. If there is a positive, there must be a negative. It’s better to prepare a realistic alternative in case you fail than to try to avoid failing. Humans are probabilistic beings. - 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"
