First of all, install OpenCV v2:

$ brew install opencv@2

Then, set build configuration for build (changing OpenCVversion number for the current one):

$ bundle config build.ruby-opencv --with-opencv-lib=/usr/local/Cellar/opencv@2/2.4.13.6_2/lib \

Keybase proof

I hereby claim:

I am odarriba on github.
I am odearriba (https://keybase.io/odearriba) on keybase.
I have a public key ASBhoTV6vzDRt3kIh3_TGsmbSVyEkqeUHVVdBj6poVd_hQo

To claim this, I am signing this object:

We create an entry on dnsmasq.d directory (used to solve domains):

$ sudo mkdir /etc/NetworkManager/dnsmasq.d
$ echo 'address=/dev/127.0.0.1' | sudo tee /etc/NetworkManager/dnsmasq.d/dev-tld

And we restart NetworkManager service (you will losse internet connection for a bit):

$ sudo service network-manager restart

First of all, we are going to store all the data in a Docker shared volume, called openvpn_data.

To initialise the OpenVPN configuration and CA:

$ docker run -v openvpn_data:/etc/openvpn --rm evolvedm/openvpn-rpi ovpn_genconfig -u udp://your-vpn.address.com
$ docker run -v openvpn_data:/etc/openvpn --rm -it evolvedm/openvpn-rpi ovpn_initpki

To start daemon (and auto-restart it):

This is my best try at transcribing of the lightning talk I gave at RUG::B on April 2016. Due to poor time management (LOL) the delivery was rushed and some examples were skipped, I hope having them posted here makes them more useful.

xargs

xargs is a small but very useful program that is installed in most if not all of your computers¹. Many of you probably know it. Those who don't will learn something really useful, but those who do will learn a couple of cool tricks, too.

Why xargs

You might have heard about the Unix philosophy:

Ghost backup script

This script allows you to automatically archive and upload a backup of your existing Ghost data to your Dropbox account.

How to use it

You'll need to follow this tutorial.

Then, you must create an executable script using the code of ghost_backup.sh in this gist (but modifying your blog's path and prefix).
