‘Luxury’ has a moral original sin because it is impractical and creates a sense of incongruity between the relatively rich and the poor. Thus, it is true that ‘luxury’ also carries a negative image. However, the rich do purchase luxuries regularly, with a few practical exceptions. This is because luxury items not only incur less depreciation, but their resale value often exceeds the purchase price over time. Think of luxury handbags or jewelry. To preserve or increase wealth, you must have an eye for luxury. This doesn’t mean you should live in luxury; rather, it highlights the challenge of maintaining your accumulated wealth unless you change your habits and attitude toward acquiring assets. - 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"
