17sep2006 · RailsConf Europe on index cards, part I

A note to the interested reader: These are the raw notes I jotted down at RailsConf Europe 2006. They are probably misleading, out-of-context and not particularly useful if you didn’t attend the sessions. Nevertheless, enjoy.

David Heinemeier Hansson

  • Textmate as a presentation tool
  • Later on 1.2.0rc1
  • REST, SimplyRestful

  • Demonstration of SimplyRestful
  • ActiveResource
  • SimplyHelpful: clearing up the view
  • assumptions about partial names
  • new development happens on plugins
  • Flower?

Kathy Sierra: Creating Passionate Users

  • Passion
  • Passion is not rational
  • High-resolution experience
  • Don’t focus on the tool, but what to do with it
  • Conversational beats formal
  • Flow
  • If you want them to RTFM, write a better FM.

Evan Henshaw-Plath: Integrating Asterisk and Rails

  • PHP of telephony: ugly and hackable
  • Evil apps: “To enlarge your penis, press three.”
  • call routing and transcoding platform
  • configuring Asterisk—sendmail.cf

  • Bonus: reuse RJS elsewhere
  • Don’t use DOM if CSS is enough

David A. Black: Relational Database Engineering and Rails

  • Are Rails databases well engineered?
  • Lessons from REST and CRUD
  • Return to the protocol is not a step back
  • Normalization is good
    • never heard of with respect to ActiveRecord
    • good
  • ActiveRecord databases are application databases
  • REST and CRUD converge
  • 80%-baked database engineering
    • first normalize, then AR-ify

Thomas Fuchs: Adventures in JavaScript testing

  • use alert() only when appropriate
  • unit-testing JavaScript
  • using Rake to automate tests with the javascript_test plugin
