Every benefit comes with costs and expenses. There can be no benefit without costs and expenses. Receiving a gift actually incurs costs and expenses. Whether we give our time or spend money to maintain a relationship with the giver, we are paying in some way. Even inheriting a parent’s legacy comes at a cost and expense. Since costs are incurred before gains, it’s more advantageous to learn how to manage spending effectively rather than just earning money to build wealth. Costing the cash is called INVESTMENT. Whether it is a wasteful investment (consumption) or an investment to accumulate value, this decision is ultimately up to you. - 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"
