synchronise_clocks.ino - this program sets the clock on the device to the date and time of
compilation: run it at the same time on both boxes to synchronise them
it_takes_two_cache.ino - this is the program that runs on both boxes when they're to be
deployed to the field; some constants need setting:
* SALT - needs to be set to a random number (the same for both boxes); this helps to prevent

Perform pixel-analysis on OpenStreetMap tiles to estimate water coverage of a graticule. More info: https://danq.me/2018/08/21/graticule-water-coverage-calculator/

* Given a graticule (e.g. 51 -1), returns the percentage water cover
* of that graticule based on pixel colour sampling of OpenStreetMap
* tile data. Change the zoomLevel to sample with more (higher) or less
* (lower) granularity: this also affects the run duration. Higher
* granularity improves accuracy both by working with a greater amount
* of data AND by minimising the impact that artefacts (e.g. text,

Experiment to use OpenSSL to establish an EV-capable CA and issue illigitimate certificates which will be accepted and displayed as full valid EV certificates by Microsoft Internet Explorer and Edge on appropriately-configured Windows computers.
#!/bin/bash
# The following steps, which were tested on Ubuntu 18.04 LTS and on the Ubuntu-powered Linux for Windows Subsystem on Windows,
# will:
#
# * Compile a recent version of OpenSSL (you can skip this step and use your package maintainer's version if you prefer, but you
# might have to tweak a few bits)
# * Create a separate set of configuration files suitable for configuring a basic CA capable of signing EV certificates
# * Create such a CA (hackerca.local / HackerCA EV Root CA)
# * Create a certificate request for a site, hackersite.local, belonging to company "Barclays PLC [GB]"
