Big list of http static server one-liners

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Store the processed image on the datastore before being served by dragonfly (pre-caching). The url needs to be accesses programatically, like in a background job.
# store the job before it has a chance to be served by dragonfly
images.configure do |c|
c.define_url do |app, job, opts|
thumb = ThumbTracker.where(job: job.serialize).first
unless thumb
uid = job.store
thumb = ThumbTracker.create!(
:uid => uid,
:job => job.serialize
)

debug SystemStackError in ruby 1.9

This is how I debug SystemStackError when there is no stack trace.

My first attempt was:

begin
  a_method_that_causes_infinite_recursion_in_a_not_obvious_way
rescue SystemStackError
  puts caller
end
