New description:

Systems Programming for Modern Applications

An introduction to systems-level concepts and technologies underlying modern, Internet-facing applications. Focus is on functional languages, databases, concurrency, and distributed systems. Topics include: ???, security concerns in modern distributed applications.

Rationale: the course is designed to be a systems programming course for modern applications that must exist in an internet, web-connected world.

Assumed Background

Students should:

know how to program imperative and object-oriented programs (Java-style), to the point of creating simple GUI-based programs and implementing standard simple data structures (lists, trees) and associated algorithms (search).
have some background in systems programming, particularly UNIX systems programming. As such, they should know about processes and threads as abstractions and should be exposed to concurrency and network sockets.
have interacted with modern websites.

Learning Objectives

Be able to partition distributed application functionality between client and server in order to make appropriate trade-offs for latency, bandwidth, reliability, and security.

Learn how to use closures and other meta-programming methods to create efficient, expressive programs in a distributed systems context.

Understand how to create and use databases as a persistent store for distributed, online applications such as web applications, including how to design schemas that are both scalable and reliable.

Be able to choose whether an SQL or a NoSQL-type database is appropriate for a given application.

Learn how to create efficient code (in time and space) in dynamic languages such as JavaScript and PHP.

Be able to implement a simple yet responsive (low-latency user interaction) web application consisting of client side code, server side code, and a database for a persistent store.

Be able to create distributed applications that do not contain common security vulnerabilities such as cross-site scripting, cross-site request forgery, and SQL injection attacks.

Learn how to choose appropriate data representation and exchange protocols for distributed applications, including the trade-offs between using XML, JSON, and custom representations.
