Code Lean and Mean

In days of yore it was a badge of honour to be able to fit a full file manager, spreadsheet application, appointment reminder and Tetris Easter Egg within a 32KB executable.

Kids these days are hard pressed to get "Hello, World" in under 4MB so we're going to wind back the clock.

The Challenge

Create an application that will calculate and display the changes between two text files as fast as possible using the least amount of memory possible. Provide timing data and maximum memory use data to prove you're the leanest and meanest.

There will be 3 categories:

  1. C/C++
  2. .NET (any language)
  3. Any other language

Once you have created your application and posted it as an article, post a link in the forum below so we can all view and comment on it.

Notes

  1. You can wrap your solution in a GUI if you wish, and there's no need to report memory usage or speed of the framework you use to support your code.
  2. The format of the files is unimportant. Treat them as plain text.
  3. Some runtimes such as .NET have a large working set already. You only need to report the maximum amount of memory your code uses above and beyond the base working set needed by the underlying runtime. If. while calling runtime methods, member is allocated then if possible this will have to be taken into account.

Test Data

All applications will use the same data. This file contains two large HTML files that have a small number of changes.

The competition ends Midnight August 31, 2009.

The prize

T-shirt

Fame, adulation and a Code Project T-shirt.
