List all Docker images in a Shell-friendly format (optionally, JSON too)
#!/usr/bin/env python
# Created by M. Massenzio (c) 2017.
# The output of `docker images` is easy on the eye, but not
# terribly helpful if you want to pipe it into further shell
# commands; and using `cut` only gets you so far (in fact,
# not very far at all).
# This script emits the list of Docker images on your system

Describes how to install and run GTest, a Google framework to conduct unit testing in C++

Build and install Google Test

Download the latest_ (1.7.0) from Google Code (Q: where is it going to live, once GCode shuts down?)

Then follow the primer_, but more to the point, the README (YMMV) Having installed CLion and cmake, this is how I built gtest:

brew install cmake
cd gtest-1.7.0

Apache Mesos build and install scripts; optionally runs the Master/Slave locally and executes a demo (C++) framework against it, to validate it all went according to plan

Apache Mesos Build scripts

The `Getting started`_ instructions are a good start (no surprise there!) but are somewhat incomplete and currently look a bit outdated (I plan to fix them soon): however, the outcome has been that I have struggled more than I felt necessary in building and running Mesos on a dev VM (Ubuntu 14.04 running under VirtualBox).

Some of the issue seem to arise from the unfortunate combination of Mesos Master trying to guess its own IP address, the VM being (obviously) non-DNS resolvable and, eventually, the Slave and the Framework failing to properly communicate with the Master.

In the process of solving this, I ended up automating all the dependencies installation, building and running the framework; I have then broken it down into the following modules to make it easier to run only parts of the process.
