On software engineering hermeneutics
When I use a word it means just what I choose it to mean — neither more nor less. Humpty-Dumpty in Alice through the Looking Glass In my recent round of TDD clarifications, one surprising experience is that folks out … Continue reading
On rational myths
In my research field, one characteristic of institutions is their “rational myths”; ideas that people tell each other are true, and believe are true, but which are under-explored, unverified, and under-challenged. Belief in these myths leads to supposedly rational actions … Continue reading

On this day 80 years ago, 16th November 1943, the villagers of Tyneham near Lulworth was evacuated to allow Allied military forces to prepare for D-Day. Despite promises that the evacuation was temporary, the UK lurched directly from the second … Continue reading
In which things are given names

Re-evaluating second brains
Because my undergraduate Physics teaching drilled into me the importance of keeping a lab book, I’ve always kept notebooks throughout my professional career too. If I want to know (and I’m not sure why I would) what process I created … Continue reading
Type safety, undefined behaviour, and us
There appears to be a shift towards programming languages that improve safety by providing an expressive type system, automatic memory management, and no gaps in the specification that lead to “undefined behaviour”. If your program is consistent with the logic … Continue reading
On legitimacy and software engineering
More than 400,000 software engineers have lost their jobs in the last couple of years, I wouldn’t be surprised if it’s really significantly more than half a million as some won’t have been documented anywhere that the tracker project saw. … Continue reading
