I am a college CS prof and have, over the years, put together educational videos for my students and anyone interested in learning computer science. I am currently producing a "Build your own javac compiler" course, with 8 videos already out. On my channel, you'll also find a 158-video "Discrete Structures" or "Math for computer scientists" course. Finally, several other playlists cover computer security topics. I post videos at least once a week. Looking forward to your feedback.
