Weird Ruby variable assignment behavior
puts defined?(hello).inspect # => nil
puts "this will not print #{hello.inspect}" rescue nil
hello = 'dude' if false
puts defined?(hello).inspect # => "local-variable"
puts hello.inspect # => nil
# Outputs:
#
# nil
# "local-variable"

Last active August 29, 2015 14:14
Personal notes from last time I added a disk to my RAID, so I've one got compact place to find all steps next time.
  1. Prepare disk with gparted:
  2. Terminal: - sudo DISPLAY=:5 gparted
  3. Device > Create Partition Table: - Partition table type: gpt
  4. Partition > New: - Create as: Primary Partition - File system: ext4
  5. Edit > Apply All Operations
  6. Partition > Manage flags:

Crazy hack way to debug Cucumber runs in PhantomJS with a real browser.
# Visit printed URL in a real browser. When done press enter/return to resume
# Cucumber run.
Then(/^log current URL$/) do
STDOUT.print " >>>>>> current_url: #{current_url}"
STDIN.gets
end
