Requirements

no upfront installation/agents on remote/slave machines - ssh should be enough
application components should use third-party software, e.g. HDFS, Spark's cluster, deployed separately
configuration templating
environment requires/asserts, i.e. we need a JVM in a given version before doing deployment
deployment process run from Jenkins

Solution

Gmail Filter by Search Query

This program, in the form of a configuration script and a main script, allows for complicated Gmail search queries to be used as filters. It also lets you do more advanced stuff you can't do with ordinary filters, like label based on whether an email contains a specific kind of attachment.

Installing

Go to script.google.com.
Go to File > New > Script File, and type Main as the title for the new script. This will be for the main script.
Delete any pre-filled text in the script file, and copy main.gs from this gist to that file.
Go to File > New > Script File again, and type Config as the title for the new script. This will be for configuration.

As of writing, this is only possible with my fork of pandas, but hopefully it will make its way into the main pandas stable branch.

The purpose of the fork is to let you specify a custom html formatter for individual columns in a data frame.

In this example we create a formatting function which takes a numpy array and returns a string of the form <img src='--base64-encoded-data'/>. This means that the numpy array is displayed as an image.

Below is the code we use to define our custom format function. Note that the function takes a single element from the data frame and returns and html string::

	#!/bin/bash
	set -euo pipefail
	IFS=$'\n\t'

	# primary name server ips
	primary=(192.0.2.2 2001:db8:1::53)
	# secondary name server ips
	secondary=(192.0.2.3 2001:db8:2::53)
	#salt for NSEC3
	salt=$(head -c 512 /dev/urandom \| sha1sum \| cut -b 1-16)
