Last week my former colleague Doug Todd asked a question about recording decisions on BlueSky: Of course I replied suggesting Architecture Decision Records (ADRs), with a pointer to the at_protocol GitHub repo where we use them. A few days back Doug demoed how he’s using ADRs with his coding assistant (Claude and Claude Code), and […]

Python script dependencies
TL;DR ‘–break-system-packages’ sounds scary, but (after some careful evaluation) is likely to be the right way to go for infrastructure automation, at least until uv is ready for production. Python venvs seem to be what we’re expected to use, but introduce additional complexity and associated fragility, which seems to make them a poor choice for […]

TL;DR I’ve been using Advent of Code as a way to practice Dart, try out ChatGPT, and learn from how other people approach the problems. ChatGPT quickly disappointed, but there’s still been plenty to learn, and I’ve found some things I’ll definitely take into my future coding. Also (value judgement here) I’m finding it much […]

TL;DR Bad input validation is the main underlying cause of many application security issues, because we haven’t made it easy enough for developers to implement good input validation. So how about a TypeScript[1] like language to resolve that – ValidScript – a language that makes it easy to do input validation? Background Wendy Nather recently […]

Background I use Enterprise GitHub at work, and public GitHub for my own projects and contributing to open source. As the different systems use different identities some care is needed to ensure that the right identities are attached to commits. Directory structure I use a three level structure under a ‘git’ directory in my home […]

Marginal cost of making mistakes
In a note to my last post ‘Safety first‘ I promised more on this topic, so here goes… TL;DR As software learns from manufacturing by adopting the practices we’ve called DevOps we’ve got better at catching mistakes earlier and more often in our ‘production lines’ to reduce their cost; but what if the whole point […]

Originally posted internally 16 Aug 2016: The title of this post comes from a tweet by Evan Goer I saw last week. It’s derived from Michael Pollan’s statement from In Defence of Food: ‘Eat food. Not too much. Mostly plants.‘ Write code Just as food fuels our bodies, code fuels our industry. The world is moving […]

Rather than replying to him 1:1 by email I’m writing here because I’d like to have a more open debate. Before we start… take a look at […]

Originally posted internally 6 Jan 2016: I’d meant to post this before the Christmas break as a guide to things to tinker with over the break, but then I hit the point where pretty much everybody seemed to already be on leave, and it was clearly too late…. So Happy New Year, if you’re not already […]

micro:bit Simon
The BBC micro:bit is a computerised project board that’s being given to every year 7 (11-12yr old) kid in the UK. It’s supposed to encourage experimentation and learning to program in the same way that the BBC Micro (and associated BBC programmes) did back in the 80s. I’ve been pretty excited about it since the announcement, […]
