Last active April 9, 2018 22:47

Bash script to download packages locally, then install them on a Kinova MOVO robot

	#!/bin/bash
	# Acts as a proxy for apt-get - downloads packages on the local (devlopment)
	# machine, then copies them to movo1 and movo2 and installs them
	# It is suggested you run this in a temporary folder, as it downloads packages
	# to the current working directory

	# Caveat: Your movo-dev machine must be running the same ubuntu version and
	# architecture as the movo machines (14.x, x86_64), otherwise it won't grab the
	# correct packages

Minimal test-case for undefined compiler behaviour when using the C/C++ defined() operator

	/**
	* Simple testcase for compiler-specific behaviour with the defined() C++ operator
	* The spec states that if defined() appears as part of macro expansion, the behaviour is undefined
	*
	* On GNU cpp treats it as a genuine define() operator. Visual C++ doensn't.
	* This generates many warnings when compiling e.g. the BSON library under Windows
	*
	* See https://gcc.gnu.org/onlinedocs/cpp/Defined.html for details
	*
	* On Visual C++ this program generates the following;
