A Capistrano Rails Guide

by Jonathan Rochkind, http://bibwild.wordpress.com

why cap?

Capistrano automates pushing out a new version of your application to a deployment location.

I've been writing and deploying Rails apps for a while, but I avoided using Capistrano until recently. I've got a pretty simple one-host deployment, and even though everyone said Capistrano was great, every time I tried to get started I just got snowed under not being able to figure out exactly what I wanted to do, and figured I wasn't having that much trouble doing it "manually".

Library websites are notoriously hard to use. Librarians and library staff spend much of their time training our patrons to use our online tools, instead of helping to develop deeper skills. While our tools are often complex, they seem to have been designed for the computers they run on rather than the people who use them. This issue has rightfully come to the forefront of the library world in recent years.

The usual debate is between making our tools so simple that anyone can use them, or training our patrons to use the complex tools. But there is middle ground here. We can make our tools easier without losing the power that much of their complexity brings. But we need to shift the burden of teaching how to use the tools from our staff to the tools themselves.

In this presentation, I'll talk about what we can learn from fields like evolutionary psychology and video game design that will help us build helpful and powerful websites that people can actually use.
