Created December 18, 2017 05:59
Finally a clean way to update dictionaries in python if you're unsure all keys exist
your_dict = {}
for i in some_iterator:
your_dict[i] = new_value if i not in your_dict else your_dict[i]+new_value
'''a version with the new value coming from a new dict'''
your_dict = {}
for i in some_iterator:
your_dict[i] = new_values[i] if i not in your_dict else your_dict[i]+new_values[i]
'''a kinda dumb example; letter frequencies'''

Work-at-home Challenge for Blue Bottle Coffee DevOps Engineer

DevOps Coding Challenge (Allot at least 2 hours)

s3 manipulation

  • Clone the read-only bucket https://s3-us-west-2.amazonaws.com/bbc-devops-challenge/, and its contents into your personal s3 account. Read through each JSON file located on this your copy of this bucket. If the key "bump_waste_threshold" is not present in any .json files, add this key with a default value of '.23' and replace the old file.

Directory microservice

Generate a web application in a framework of your choice that does the following:

  • Connects to the s3 bucket cloned above, and stores a text representation of the subdirectories of the bucket in Redis (or a similar key-value store). This text representation should match the output format of the unix command tree. Additionally, store the json files as the values with keys given by their paths from the root of this bucket.
  • Serves the plain text of the directory tree from the root path of the application.
  • All non-root paths must return a sample of poetry(any
