What and How

This first class will introduce you to CSCI-E28.

Frame 1: Course, Staff, askcscie28@gmail.com

Frame 2:

Here is the outline
     Where are we going?
     How we get there?
        - course mechanics
        - context, overview
        - operating environment
        - our approach


Frame 3:
     Where are we going?
       - by the end you will understand,
         written, and will know enough to write:
          [a] the Unix bc tool
          [b] Internet multi-player bridge
          [c] Web browswer, server
       - What ideas do we need to learn to understand
          and/or write these?
       - Let's start with bridge
          multiple users, distributed data
          communication, cooperation, coordination
       - Then we look at bc -- seems totally different
          but in fact, it is like bridge
          communication, cooperation, coordination
       - Then we look at web browser/server
          two players, communicate, cooperate,
          coordinate



Frame 4:
     Course mechanics
       - look over the sheet
       - explain the way the course works

Frame 5:
     Our first step: Taking the bigger picture
     Old view: single program in isolation
     New view: multi user/task/devices
     Big idea: operating system - split the work

Frame 6:
     What does this system look like to the user?
     Login, run, logout
     storing, getting, putting data
     files, directories
     dir commands: mkdir, cd, rmdir, ls, pwd
     file commands: cat, more, chmod, rm, mv
     data flow: pipes, <, >


Frame 7:
     Learning by building: let's write more
