• I’ve been working this week on mongo replicasets and I’m very impressed with their resilience, particularly the use of an intelligent client in the driver to handle failover etc.
• As part of an initiative at work, I started playing with Amazon Q, initially asking it to generate some basic arcade games. First impression was to be impressed at the simple examples produced, while being aware of the challenge in getting precise results from a coding agent. Something I need to spend more time on.

• An excellent post from Sean Goedecke, AI Interpretability is further along than I thought, talks about internals of language models – it was a useful reminder of why telling a chatbot that it’s an expert works.
• AI-assisted coding for teams that can’t get away with vibes (via Simon Willison) was a useful primer on large-scale coding with GenAI. A useful rule here was ‘what helps the human helps the AI’, including linting, CI/CD, documentation and clearly defined features. Some good examples around prompting, and how AIs are used to build the prompts to code from. The most interesting bit, and something I’d like to go back to, is the claim that the DRY principle is less useful when working with LLMs. This is a living document being maintained by nilenso, which I will have to keep an eye.
• Could HTTP 402 be the Future of the Web was a good speculative article about the need for micropayments and how charging AI crawlers could lead to that.
• Some excellent words of wisdom from Everything is Prioritization: “If you’re remote and still free frazzled, you’re not doing remote wrong. You’re just prioritizing availability over impact.” The article talks about the need to avoid tempting distractions: “The best teams aren’t full of geniuses. They’re full of people who keep their focus and say ‘no’ without having a breakdown”.
• I’ve long disliked the cargo cult metaphor, and this is deconstructed in The origin of the cargo cult metaphor, which points out a lot of the errors and miscomprehension in the popular understanding of actual cargo cults. “The cargo cult metaphor is best avoided”.
• Simon Willison’s Identify, solve, verify is a short piece on the role of the programmer in the era of GenAI. “The more time I spend using LLMs for code, the less I worry about my career”.
• The Elegance Question: What Makes Some Systems Just Work? set out some simple principles for building ‘elegant’ systems. This was thought-provoking, particularly around the question of why so many systems go against these principles.

Books

No time for reading this week – and I’ve been distracted by a non-tech book.

• I’m going to try writing a few weeknotes to see how they feel. I need some way to consolidate everything I’m reading and thinking about, but longer blog posts are not coming together. These weeknotes will help me track my technical interests – and hopefully help me find interesting blog posts when I need to refer back to them.
• Last Sunday, I had an interesting conversation with Laurence where I found myself asking whether agile is too hard for most teams. Laurence pointed out out that the core of agile is simple, but it does place a lot of demand on developers. I think the widely perceived failures of agile need much more consideration.
• In another discussion with Laurence, I realised how vital GenAI skills will be for technical managers – there is a huge change in software development coming and staying current will require understanding those skills – not least to be able to support and unblock those who use them most.
• Something I’ve not blogged about over the past few weeks is the decline of stack overflow. It’s been interesting to see how the references for learning technical skills have changed over the years.
• One of the things I like most about working in a large consultancy is the number of talks and activities going on. An ‘unadvent of code’ group has started to look at the Advent of Code puzzles from 2018. This has got me playing with Go as a coding activity, which I’m enjoying.

• I watched the video Java for AI by Java Library Architect Paul Sandoz – another example of the Java platform’s strength as a combination of JVM, libraries. It’s will be good to see Java become a first-class platform for AI
• AI Is Poised to Re-write History is an interesting article looking at GenAI as a reading machine rather than a writing machine. It also interviews Mark Humphries, who was discussed in the excellent Feb 2024 Verge article How AI can make history

Reading

Writing for Developers

I started reading this book, a recommendation from my colleague Matt. The book could probably be titled ‘Blogging for Developers’, and it’s interesting to see someone writing such a book in 2025. I like the book, but I definitely have philosophical differences with it, in that it focusses on blogging as a way to go viral, sometimes neglecting the more personal uses of blogging (such as weeknotes). A good counterpoint occurs in Simon Willison’s piece on keeping a link blog.
