Laser Printers

16Jun18

My family prints a lot[1] – about 1200 pages/year, which is why I made the decision almost a decade ago to switch from inkjet to laser. Inkjets weren’t just costing me a fortune in ink; they were also costing me a fortune in printers because they kept clogging up and failing in various ways. I […]


I’m starting to see companies abandon Pivotal Cloud Foundry (PCF) in favour of Kubernetes distributions such as Red Hat’s OpenShift; and it’s almost certainly just a matter of time before we see traffic in the opposite direction. My suspicion is that this is nothing to do with the technology itself[1], but rather that early implementations […]


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 […]


TL;DR I’ve been very happy with the X250 – it’s given me the same performance I got from my X230, but with better battery life, a smaller form factor and it seems more robust. Long term review I started writing this post in January not long after I got my X250, but I never got […]


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 […]
