Engineering topic: Less is more

I had a desktop wallpaper a while ago with a single quote, it read:

As a software developer, you are your own worst enemy. The sooner you realize that, the better off you'll be.

As developers, every line of code that we write increases the const of maintaining the project that the code is in. It doesn't matter how clean the code is, how well written it is, how much thought was put into it ahead of time or if it has been refactered: All code carries a debt that can only be paid in time.

The theme of this week's engineering essay: Use the least amount of code possible.

Goals:

• Support Coffeescript testing
• Headless - run from command line
• Test can be written in Coffeescript

Test libraries, two main alternatives:

• Jasmine
• Mocha

Jasmine is older - actively maintained by PivotalLabs, de facto JS testing for Rails projects? So I'd expect there are more gems/projects that integrate Jasmine and Rails compared to Mocha (at the moment anyway).

Introduction

Imagine one was required to create a web-based password management system (over SSL! :) with the following requirements:

1. Individual users sign in to the system using their own unique pass phrase.
2. This pass phrase should be enough to allow the user to use the system effectively (e.g. from a smartphone, etc.)--the point being that they should not have to keep a key file with them.
