Program Design: How to Help Programs Debug Themselves
Prerequisites

Thu 25 Feb 2010

Description

This course is part of the Scientific Computing series.

This course is intended for serious programmers who need to develop large or complex codes, or to write applications that will be used and worked on by other people or over a long time (years). It will describe some of the design and coding techniques that can make debugging easier (sometimes even semi-automatic), and reduce the overall development and maintenance effort by spending a bit more time during design and coding.

It is applicable to any conventional language, from Python to Fortran to Java to C++ and even assembler, and will describe the techniques in generic terms. It should be regarded as part of the practical end of software engineering - everything covered will be something that the speaker has found to be useful in practice.

Prerequisites

Significant experience with a conventional language; it is assumed that the audience has written at least a 1,000 line program or done comparable modifications to an existing program, and is working or planning to work on a bigger one. Users with less experience may benefit from the course, or they may get confused.
