> Learn how it works by looking into the source code Yes, now he can do that. He's at that level now. He never was before. I think you and OP are just disagreeing on what "knows how to program" means. To me, he described reaching the point where he can actually do what you suggest. Not "becoming a software engineer". You can't just pick a software project and learn things from it if you're still at "what the fuck does this ampersand do?"
