CSS trick on word-wrap for table content

Just came across this scenerio... word-wrap on table td's don't work the work around for this is adding a wraper div and then applying word-wrap:break-word on it. But then this is not a semantic solution whichc adds extra divs around content.

Another work around is adding table-layout:fixed on the main table and then addding word-wrap:break-word on td's.

A subtle difference between Ruby's Hash.fetch(:key, :default) vs. (Hash[:key] || :default)
h = {
'a' => :a_value,
'b' => nil,
'c' => false
}
h.fetch('a', :default_value) #=> :a_value
h.fetch('b', :default_value) #=> nil
h.fetch('c', :default_value) #=> false
h.fetch('d', :default_value) #=> :default_value

The command to type into terminal to install homebrew is:

Rails Rspec model testing skeleton & cheat sheet using rspec-rails, shoulda-matchers, shoulda-callbacks, and factory_girl_rails. Pretty much a brain dump of examples of what you can (should?) test in a model. Pick & choose what you like, and please let me know if there are any errors or new/changed features out there. Reddit comment thread: http…
# This is a skeleton for testing models including examples of validations, callbacks,
# scopes, instance & class methods, associations, and more.
# Pick and choose what you want, as all models don't NEED to be tested at this depth.

# I'm always eager to hear new tips & suggestions as I'm still new to testing,
# so if you have any, please share!
