For just ~$30 in parts (Raspberry Pi, 3.3V Relay board and a few wires) you can build your own power switch that will switch on if a streaming ILP payment comes in. Payment stream stops? Power turns off.

Is this useful? Well, right now… Not really, right? There’s no easy way for people to start streaming XRP to you over ILP, but… That may change ;)

I hope I can guide you through the process of installing your Raspberry Pi and wiring your Pi to your power socket.

WARNING: YOU ARE GOING TO WORK WITH HIGH VOLTAGE ELECTRICITY! IF YOU DON’T KNOW WHAT YOU ARE DOING (or at least: the electricity / wiring part) PLEASE DO NOT SWITCH 110V/220V, BUT SWITCH A SIMPLE LOW VOLTAGE LED INSTEAD.

Depending on your experience with hard- and software it may take you between 30 minutes and a few hours to complete this howto. …

Vue (pronounced /vjuː/, like view) is a progressive framework for building user interfaces.

Using VueJS, you can combine writing HTML and Javascript. Vue will then keep your Javascript objects and HTML in sync. This means your events in your DOM (HTML) can mutate the VueJS Javascript objects, resulting in modifications in your DOM (and the other way around).

Here is a simple example — This small piece of HTML + VueJS code allows you to add and remove Todo’s.

You can use Vue in vanillajs projects (so: just write plain old Javascript), but you probably want to do a bit more. …


If you operate a validator or rippled Docker Container (howto) the upgrade process is pretty easy. I intend to update the Docker Hub container images to the most recent rippled version ASAP, so all you have to do is re-create your container based on the newest image.

If you used the Github repositories (docker-rippled, docker-rippled-validator) there are instructions at the end of this article.

Docker Hub

If you just followed the instructions in the Howto and created a container, the old container image was fetched from the Docker Hub automatically. …


So you decided to run your own Ripple Validator? Great! You didn’t? Check my Howto on running a Ripple Validator on a DigitalOcean server.

If you got your validator running, you probably looked it up in the Ripple Validator Registry. It’s cool to see your own validator listed over there, but it would be even cooler to have the Validator Registry show your own domain in green, right?

Follow the four steps in this howto (5~10 minutes) or jump all the way to the bottom for the screencast of this Howto.

Only verified validators have a green domain name and check mark next to it.

If you own a domain name and you have access to DNS management for your domain, you can think up a subdomain, and create an A-record pointing to the public IP of your your Docker host. …


So you want to contribute to the Ripple XRP Ledger & decentralization. You want to run a validator. If you have your own Docker host somewhere, just pull the image.

If you don’t have a server and you want to spin up one at DigitalOcean for $20 a month, just follow the next steps. You’ll be validating in 10 minutes!
