A colleague asked me the other day how to get started with GitHub on a Windows machine, and I ended up doing a quick screen share to show him my usual setup. Thinking that it’s likely a common question I’ve put together a quick screencast of installing Git Bash and Atom on Windows, and using […]


Last week Jérôme Petazzoni did an excellent (abbreviated) version of his ‘Deep dive into Docker storage drivers‘ at the London Docker Meetup. If I wasn’t convinced enough by that, Jessie Frazelle hammered home the same point in her QCon Presentation – AUFS is where it used to be at, and the new king is Overlay. I set about […]


TL;DR The Administrator setup for Google Apps Migration guide makes things look pretty straightforward, but it’s much, much more complicated. What should be just a couple of check boxes turned out to be a twisty turny journey through hidden menus littered across distant parts of the administrators console. Background The move from CohesiveFT to Cohesive Networks […]


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 […]


I was helping a colleague troubleshoot a deployment issue recently. He’d set up a virtual private cloud (VPC) in Amazon with a public subnet and a bunch of private subnets: 10.0.0.0/16 – VPC (the default) 10.0.0.0/24 – Public subnet 10.0.0.1/24 – Private subnet 1 10.0.0.2/24 – Private subnet 2 10.0.0.3/24 – Private subnet 3 Everything was behaving […]


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 […]


The second release candidate for OpenELEC 3.0 (featuring XBMC 12 ‘Frodo’) is now available (official announcement). There have been a flurry of changes over the past few weeks (over 275 by my count), but the OpenELEC team are saying that this will be one of the final release candidates before 3.0 final. If you’d like […]


The first release candidate for OpenELEC 3.0 (featuring XBMC 12 ‘Frodo’) is now available (official announcement). If you’d like to download an SD card image to install on a Raspberry Pi then it’s available from the official_images section of the Pi Chimney resources site. RC1 is 2.99.1, and later builds will be available from the […]


I set $son0 a summer holiday challenge of building an alarm system that would send an email (and it seems that I’m not alone). I was pleased to see that the latest edition (#4) of Magpi has an alarm project so we set about building it together. The hardware came together pretty nicely, but the software […]


In part 1 I went through setting up an SSH tunnel, and waking up machines on the home network. In this part I’ll run through how to use various protocols and clients to connect to machines on the home network. SSH tunnels on PuTTY SSH lets you tunnel many other protocols through it (using a […]
