Installing OpenCV-3.2.0 on Ubuntu 16.04

The following steps have been tested for Ubuntu 16.04 but should work with other distros as well.

Required Packages

GCC 4.4.x or later
CMake 2.8.7 or higher
Git
GTK+2.x or higher, including headers (libgtk2.0-dev)
pkg-config

The specificity of my setup, is that the Raspberry won’t be a router but a bridge. DHCP is thus delegated to the main ADSL router and all devices connected to the AP will appear on the same network than other devices. The instructions below are based on a fresh Raspbian lite install so that it can be reproduced easily.

Install the required packages :

$ sudo apt-get install -y bridge-utils hostapd

To create a bridge, we need to enable ip_forward in the kernel, for that, edit /etc/sysctl.conf and remove comment (#) from the following line :

How to Shrink the Cloned Raspberry Pi Image (Linux-only)

These methods create an image file that is equal to the total capacity of the SD card. For example, cloning an SD card with a capacity of 32GB will create an image file of 32 GB, even if only 5 GB is actually in use on the card. This is fine if you only have one or two such images, but any more than that (especially if you use an SSD) will cause you to run out of space. Unfortunately, this tool is only available on Linux. If you do not have Linux installed, you can install the latest version of Ubuntu or Linux Mint in a virtual machine, and run this script there:

shrink.sh

#!/bin/bash

It’s VERY easy to setup your own VPN with docker. This guide assumes you’re ok with operating a linux box but know nothing about docker. I’ll break it down into easy steps:

Setup a docker host

Install docker on the host:

$ curl -sSL https://get.docker.com/ | sh

Run the docker image

Make directory for docker volume:

$ mkdir $HOME/openvpn-data
