Learnings for Week 18 2010

Learnings for the past week.

• more vim fun
  • zf5j to fold the next 5 lines
  • zo to open a fold
  • zc to close a fold
  • c in visual block to substitute
  • ctrl+_ to complete html tag (with closetag plugin)
  • ctrl+w+_ to maximize splits vertically
  • ctrl+w+| to maximize splits horizontally
  • ctrl+w+= to equalize splits
• after_initialize in a ruby model if you want something to happen when both new or create are called
• instance_eval can be given a block. This is really powerful if you want to whip up a quick DSL to clean up some code (highly recommended).
• Devise authentication plugin dropped support for MongoMapper until it conforms to ActiveModel (MongoMapper is in turn waiting until Rails 3 is final before making this change)
