No~~~~~~~~~ You met me in a Linux lecture?? Where is it... P company? Linux is my favorite operating system. Also, operating systems are my favorite technologies. Rather than just showing you what I know, I create them so that you can learn the technology that fits the purpose of each lecture. I also hope that these parts have a positive influence. I believe that the reason you caught these parts is because you are wise enough to notice them. Then, you will understand and be able to utilize the technologies you want better. Thank you.
