Open Source and Export Controls
This is the blog version of a Twitter conversation with my colleague Graham Chastney. Huawei, and the war on trade POTUS #45 has been pursuing a ‘trade war’ with China, as this appears to be popular with his base, even though it makes stuff more expensive for them and will ultimately harm the US economy. […]

Swift Playgrounds
I mentioned Swift Playgrounds in my Learning to Code post a few years back, but at that time I didn’t have a new enough iPad to try it for myself. That changed when I recently got an iPad Mini 5[1], so I’ve been running through the Learn to Code modules. It’s like a puzzle game, […]

Skills development and training is a huge part of driving an organisation forward into the future, and so it’s something that I spend a lot of time and energy on. I’ve seen a bunch of stuff over the past year that leads me to expect a revolution in training. Katacoda I first came across Katacoda at […]

Silent PC
TL;DR I’ve been very happy with the silence of my passively cooled NUC for the past 4 years, but it was starting to perform poorly. So when I came across a good looking recipe for a silent PC with higher performance I put one together for myself. Background I’ve been running my NUC in an […]

#2 of jobs that should exist but don’t in most IT departments (#1 was The Application Portfolio Manager). What’s a constraint? From Wikipedia: The theory of constraints (TOC)[1] is an overall management philosophy introduced by Eliyahu M.

#1 of jobs that should exist but don’t in most IT departments What should we do about all the legacy stuff? This was a question that came up at the closing panel of the Agile Enterprise Rome conference I was at in May. The context was ‘we’ve spent a couple of days hearing about this […]

Laser Printers
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 […]

The PCF K8s flip-flop
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 […]

Home Lab/Network
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.
