CloudFlare have made SSL available to all free subscribers to its content delivery network (CDN) with Universal SSL. The move addresses both cost and complexity issues that have previously confronted web site and application owners wanting to deploy SSL. CloudFlare takes care of issuing a certificate at no cost to the end user, and enabling SSL becomes a selection from a dropdown menu.

The WRTnode is a great new open source hardware dev board that takes the guts of a typical home router and makes it hackable. It’s more than an Arduino, less than a Raspberry Pi, and very network capable. WRTnode runs the OpenWRT Linux distribution, which I’ve used in the past on some of my home routers (to replace the awful firmware that gets shipped by OEMs).
One of its neat little party tricks is that it can be used to share a WiFi connection to multiple devices, so as I type I’m making use of that to share a hotel WiFi connection between my laptop, tablet and phone.
Developing for the WRTnode
The WRTnode Wiki has a section on OpenWRT Development with a classic HelloWorld application that’s build from source, packaged into an ipk file and installed. I struggled with this because copy/paste of the make files from the web to my text editor stripped out the tabs, and make needs those tabs otherwise you get ‘Make error: missing separator’.
The WRTnode has a number of commands to simplify getting online, which are covered in the Starting section of the Wiki. That’s fine if you can see the Wiki, but what if you need reminders of the commands so that you can get online (in order to see the Wiki)?
wrthelp is a simple command line tool (adapted from the helloworld example) that prints out the key instructions needed to get the WRTnode connected to a WiFi access point. The Github repo contains the source code and details for how to build, install and run.
Getting a working SDK was something of a pain, so I should probably Dockerise the one that I have to make it easily accessible.
I’m looking forward to doing some proper hacking with WRTnode (probably at the ThingMonk hack day.)
1. The WRTnode SDK can be run in a Docker container using:
sudo docker run -it cpswan/wrtnodesdk

Weave is an overlay networking system for Docker containers. Whilst Docker can already link containers on a single host, Weave provides connectivity for containers that are spread across multiple hosts. It has been released under the Apache 2 open source license by Zettio, a new company targeting ‘apps for the zettabyte era’ founded by RabbitMQ creators Alexis Richardson and Matthias Radestock.

One of the big news items from last week’s VMworld was the launch of EVO:RAIL, a ‘hyperconverged infrastructure’ reference design with software from VMware and hardware from a variety of partners. The RAIL part of the name comes from the smallest unit of deployment that fits into 2U of standard rack space, and onto a single rail within that rack. EVO:RAIL is described as delivering ‘compute, network, storage and management’, and it’s worth picking apart what’s going on in each of those areas.

This is my first longer article for InfoQ (rather than being a news item), and it’s intended to be a comprehensive backgrounder on Docker: ‘an overview of the Docker journey so far and where it is headed along with its growing ecosystem of tools for orchestration, composition and scaling. This article provides both a business and a technical point of view on Docker and separates the hype from the reality.’
