We'll respond shortly.
“Can I use
after_initializeto set up nested associations for use with
Not recommended. It is better to write a custom
#new_for_form method in your model that pre-populates your instance variables with the 1 or more nested objects. That way you can test drive it, too.
“DelayedJob YAML parser in Ruby 1.9 is having issues.”
psych library has issues, use the tenderlove/psych gem instead. You have to use Bundler, however. Invoking
require "psych" will use the compiled-in version.
“RubyMine is not honoring a DVORAK keyboard layout properly (it is mapping keyboard shortcuts to the QWERTY layout)”
Use a hardware dongle.
“Jenkins is trying to kill off Postgres?”
Does anyone have Jenkins CI working with Postgres? It seems that after a build is complete, some java deep down inside Hudson is trying to parse the process table, and it is choking on the Postgres entries. (Postgres re-writes ARGV to display status info, you can’t rely on it be the original command line.) It remains a mystery why Jenkins would even need this information.
“Is anyone using Chrome in CI? The windows are transparent”
Sounds pretty. Odd, but pretty.
“brew info … is your friend”

“More ‘special’ keywords to avoid in your models:
ActiveRecord Polymorphic Associations use a method called
target internally. If you have an attribute in your model / database, also called
target, then strange things will happen.
<model>.attachment.exists?is slow; it goes out to S3 (or whatever the store is)”
And it happens in strange places. Be warned. Or mock out your network calls.
