Simple, semi-anonymous backups with S3 and curl

Backing stuff up is a bit of a hassle, to set up and to maintain. While full-blown backup suites such as duplicity or CrashPlan will do all kinds of clever things for you (and I'd recommend either for more complex setups), sometimes you just want to put that daily database dump somewhere off-site and be done with it. This is what I've done, with an Amazon S3 bucket and curl. Hold onto your hats, there's some Bucket Policy acrobatics ahead.

There's also a tl;dr at the very end if you just want the delicious copy-pasta.

Write a program in Ruby that parses a dictionary file for unique sequences of letters.

Requirements:

• The program should generate two output files, "sequences" and "words".
• The sequences file should contain every unique sequence of four letters that are unique and appear in exactly one word of the dictionary file.
• Differences in casing should not reflect a unique sequence.
• Numbers and special characters should not create a unique sequence.
• The words file should contain the corresponding words that contain the sequence, in the same order, again one per line.

A future version of Ember will come with a new templating engine known as HTMLBars.

The original motivation for HTMLBars was to allow helpers and properties to have better contextual information about what they were bound to.

So for example, consider a template like this:

<a href="{{url}}">{{link}}</a>

# config/deploy.rb

namespace :upstart do
  desc 'Generate and upload Upstard configs for daemons needed by the app'
  task :update_configs, except: {no_release: true} do
    upstart_config_files = File.expand_path('../upstart/*.conf.erb', __FILE__)
    upstart_root         = '/etc/init'

    Dir[upstart_config_files].each do |upstart_config_file|
      config = ERB.new(IO.read(upstart_config_file)).result(binding)
