*** Lessons Learned?
    Q: What are the most important lesson(s) you learned?

             

    ... (my votes: modularity
                   syntax-directed analysis, follow the grammar!
                   incremental progress recorded in data structures
                       such as ASTs)
                   
** Where do we go from here?

*** practical/industry paths forward
     Q: What careers or contributions can be made in industry
         using what we have learned in this class?

------------------------------------------
       CAREERS AND INDUSTRY IMPACT

What are some ways to help programmers?


   
------------------------------------------
     ... - assembler languages
         - programming languages
         - OS libraries

     traditionally, hardware companies needed systems software people:
         - architects
         - OS and tool writers
         - assembler and compiler writers

     systems software can have a multiplier effect on productivity,
          as it enables others to be more efficient

*** practical tools needed
     Q: What tools are needed in practice in systems software?

------------------------------------------
           TOOLS NEEDED?

If a company created a new computer,
  what systems software would they need?






What should they write first?








------------------------------------------
       ... boot loader, assembler, loader, OS, then maybe a C compiler...

       ... probably in the order above

          CLASS OBJECTIVES

 - Explain and correctly use the concepts
   behind software tools, their design,
   and their role in a computer
   operating system

 - Implement, as part of a team,
   a software tool, such as a compiler

 - Evaluate, as part of a team,
   the quality of a software tool's
   implementation

------------------------------------------

------------------------------------------
         CLASS LEARNING OUTCOMES

- [UseConcepts] Use and explain concepts
  related to systems software

- [Build] Build systems software
  in a team. 

- [Appraise] Apprise the quality
  of a software tool's
  implementation in a team.
