Fun with Flocker
Before writing my InfoQ story about Flocker I ran through my now usual process of getting my 3 tier demo[1] working on it (in addition to running through the getting started guide[2]). What I found is that Flocker doesn’t yet support multi container apps, but then it is only at release 0.1 (and proper multi […]

Just as I did with Fig I had a go at composing my three tier demo app with CenturyLink’s Panamax as I was writing my InfoQ piece on the launch. You can see the resulting todomvc.pmx template file in GitHub (and see that it’s very similar to my fig.yml), but it’s a visual tool, so let’s […]

TL;DR If you’re a Three customer using a 4G capable device abroad with their Feel at Home free international roaming then you may have to manually select 3G as the network preference in order to get a data connection. Update 1: Terence Eden provides a telco insider explanation what what’s going on (or should that be […]

Boot2Docker on Hyper-V
Boot2Docker is a minimal (27MB) Linux image for running Docker. I started using it yesterday whilst investigating Docker on Mac OS X. It’s designed to work with VirtualBox, and comes with a script to control the lifecycle of the Boot2Docker VM inside of VirtualBox. There’s no reason however why it shouldn’t be used with other […]

Multi tier apps in Docker.io
Docker provides the means to link containers, which comes in two parts: Outside the container (on the docker command line) a ‘-link name:ref’ is used to create a link to a named container. Inside the container environment variables REF_… are populated with IP addresses and ports. Having linked containers together it’s then necessary to have a little […]

OpenWRT on TP-Link TL-WR2543ND
If you want to dive straight into install instructions then head over to the TP-Link TL-WR2543ND article on the OpenWRT Wiki. Why? When my son smashed the screen on my iPad 2 I think he also damaged the WiFi antenna. I had to be just about be sitting on top of a 2.4Ghz hotspot to get […]

Pi Pandora over the Pond
A friend of mine recently returned from working in the US for 3 years, where he’d got to like listening to Internet radio using Pandora. He wanted to get things set up so that he could listen to Pandora on his kitchen stereo. Challenge #1 – be in the US Pandora uses IP geolocation to […]

Sadly it’s fairly typical for corporate web filters to block ‘unusual’ ports, which means that if you’re trying to access a service that’s using anything other than port 80 for HTTP and port 443 for HTTPS then you might be in trouble. I recently came across a situation where somebody was trying to access an […]

Your own VPN in the cloud
Last week I saw that major credit card companies are blocking payments to VPN services: This is bad news if you want to protect your stuff online (or pretend that you’re in another country). One way to deal with this is to run your own VPN service in the cloud. This is of course of […]

After bringing my Nanode based temperature sensor back to life I thought about some other projects that I might do. One was simply to add an external sensor to the Nanode project, and another was to turn my slow cooker into a sous vide water bath (along the lines of ‘Sous Vader‘). Those projects would need […]
