I did exactly that. That does not teach you to write a good program. It shows you how to make a compiler in yacc and bison or whatever the current flavor is.

I did exactly that. That does not teach you to write a good program. It shows you how to make a compiler in yacc and bison or whatever the current flavor is. A skill I have had need of very rarely. Most of the time you do not need to reinvent a whole grammar with parser to get your task done. For new devs I take on. I stress good code structure, testing, regression, QA, path testing, logical layout of architecture, end user requirements and delivery of code. I assume fundamentals. If they are missing them I get them on projects where they would learn particular ones.
