Did you know that modern space rockets are influenced by Roman heritage? In other words, the size of current rockets still reflects standards set during the Roman era. Rocket components were transported by rail to launch sites and had to pass through an intermediate tunnel. It was more practical to limit the size of the rocket rather than build a new tunnel. The track width was determined by the steam locomotive, which was adapted to match the width of British wagons pulled by two horses. The width of the track is based on the hips of the two horses, which in turn are derived from the size of a Roman chariot. This phenomenon is called Path Dependency. Humans tend to stick with the past. - 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"
