Import Keybase PGP to GPG

After installing the keybase command-line tool onto a new / fresh computer, you may want to import your PGP key to the local keyring so that you may use the keys with GPG.

Import your PUBLIC PGP key:

keybase pgp export|gpg --import -

# Search term parser from https://gist.github.com/1477730
# Modified to allow periods (and other non-letter chars) in unquoted field values
# and field names.
#
# Helper class to help parse out more advanced saerch terms
# from a form query
#
# Note: all hash keys are downcased, so ID:10 == {'id' => 10}
#       you can also access all keys with methods e.g.: terms.id = terms['id'] = 10
#       this doesn't work with query as thats reserved for the left-over pieces

Scaling your API with rate limiters

The following are examples of the four types rate limiters discussed in the accompanying blog post. In the examples below I've used pseudocode-like Ruby, so if you're unfamiliar with Ruby you should be able to easily translate this approach to other languages. Complete examples in Ruby are also provided later in this gist.

In most cases you'll want all these examples to be classes, but I've used simple functions here to keep the code samples brief.

Request rate limiter

This uses a basic token bucket algorithm and relies on the fact that Redis scripts execute atomically. No other operations can run between fetching the count and writing the new count.
