Background Jess Frazelle has recently been blogging about her Home Lab, which made me realise that over the years I’ve written here about pieces of my own lab, but never the entirety. Network Wired networks are better for bandwidth, reliability and latency, so I use wired whenever I can. Taking a queue from Ian Miell’s […]


RISC-V[1] is something that I’ve been aware of via the Open Source Hardware Users Group (OSHUG) for a little while, and their most recent meeting was a RISC-V special, with talks on core selection and porting FreeBSD to the platform. Suddenly it seems that RISC-V is all over the news. A sample from the last […]


TL;DR Organisations of all types are increasingly making decisions based on data and its analysis, but the rigour involved in this hasn’t yet entered our broader social discourse. I’m hopeful that we all start getting better access to data, and better understanding of the analysis and modelling process so that decisions can be made for […]


Restoring Power

22Jan17

TL;DR I had a huge problem with ‘nuisance trips’ of the residual current device (RCD) in my house, which has been resolved by the installation of residual current circuit breakers with overcurrent protection (RCBOs). More reliable power to individual circuits in the house (and particularly the garage) has forced me to set up better monitoring so […]


Amongst the flurry of announcements at re:invent 2016 was the launch of a developer preview for a new F1 instance type. The F1 comes with one to eight high end Xilinx Field Programmable Gate Arrays (FPGAs) to provide programmable hardware to complement the Intel E5 2686 v4 processors that come with up to 976 GiB […]

Metaprogramming

26Sep16

I spent part of my weekend absorbing Rod Johnson’s ‘Software That Writes And Evolves Software‘, which introduces what he’s been doing at his new company Atomist, and particularly the concept of ‘Editors’, which are essentially configuration templates for programs. The combination of Atomist and its Editors is a powerful new means of metaprogramming. I’ll repeat […]


Let the 80s and 90s computer nostalgia continue… Between writing about how I learned to code, and watching the latest season of Halt and Catch Fire, I’ve been thinking about how the online services I’ve used over the years have shaped my view of the IT landscape. WarGames Like so many others my journey started […]


A quick overview of WebVR based on Ada Rose Edwards’ awesome ‘getting started with WebVR‘ presentation that I saw at Nineworlds Geekfest The demos that I showed off can be seen from Ada’s GitHub pages: basic demo track demo Sadly the odd colour basic demo and the T-Rex thing haven’t (yet) made it from the […]
