Suggested Skills

This is a course in web programming.  You do not need to know anything about the web- we will cover than in class.  But you should have solid grasp of programming concepts, and you should be able to create a moderately complex piece of code.  If you have any concerns, please talk to me!

Course Goals

  • Get you from 0 to 60 – FAST!
  • Understand the many modalities of Web Programming – it’s not what you may think!
  • Get your dev skills to the next level
  • Along the way, learn some very useful software tools that will serve you well in future endeavors (and look cool on a resume)
