About Instructor
avatar He Yongkang

Course: zero student: zero
Hi， My name is kev. A Linux command line geek (LESS is MORE!) often wanders around StackOverflow to exchange exotic Linux/shell/vim technologies. Love open source software, like hands-on practice, willing to share technology. Have in-depth research on various data (text, picture, video) processing. He is also interested in Python, Javascript, Raspberry PI and KaliLinux. Usually, I can quickly learn new technologies by watching a large number of computer video tutorials, and also hope to share with like-minded friends by recording videos.
