1 Agenda

• Course Objective
• History of Programming Languages
• Paradigm of Programming Languages
• Course Methodology

2 Goal

• Paradigms
  • Aware
  • Use
  • Appreciate: Why use
  • Criticize: Why not use
• Batteries
  • Strength of PL decided by its ecosystem
  • Master key libraries
  • Learn how to search, mine and use new libraries
• Web
  • Software are migrating to web/cloud
  • Success depends on how fast one could code: productivity
  • Drive the learning by web programming
    1. Case studies
    2. Projects

3 What’s PL

A language is intended for use by a person to express a process by which a computer can solve a problem.

a set of conventions for communication an algorithm.

The art of programming is the art of organizing complexity.

4 PL History

• Machine language
  • register transfers
  • encoded in binary
• Assembly language
  • one to one mapping to macine language
  • mnemonic for readibility

2 / 5

The main idea is to treat a program as a piece of literature, addressed to human being rather than to a computer.

• Plethora of languages
  • Way too many, and being invented each day
  • Few survived
  • Few is still many
• Traits of successful languages
  • Intuitive
  • Expressive
  • Efficient
  • Wide deployment (free helps)

5 PL Paradigms

5.1 Imperiative

• model of Von Nuemann machine

4 / 5

5.3 And Many More

• Object-based/oriented
• Aspect-oriented
• Event-based
• Message-passing
• Concurrent
• Parallel

6 Course Methodology

• Use a single, but multiparadigm language
  • Python
  • Very popular
  • Well designed
