"We’ve spent the last two years arguing about models. Which one is smartest, which one writes the cleanest React, which one hallucinates less. That conversation is fine as far as it goes, but it’s missing the other half of the system." New #Radar article by @addyosmani.bsky.social: bit.ly/43fulk0

A spaceship entered Earth's orbit and broadcast a message: "We are the Interstellar Library. Do you want to swap? We have thousands of stories." There were many replies. The library was silent for a whole day, then: "What do you mean, 'We have millions'?"

I see so many people obsessing over token efficiency barking up the wrong tree with bervity and compression and wotnot. They're missing The Big Factor. Inference works *recursively*. Every token in the context is fed back through to predict the next token. The big savings are in context lifetimes.

The way you adopt Agentic AI depends on your previous 'posture' for software development. It looks quite different if you were previously a TDD practitioner. In my latest video I examine the process in some depth. Video: youtu.be/_erJ5EdQFYU Blog: coding-is-like-cooking.info/2026/04/it-d...

"The role of a business analyst is not writing documents. It's understanding the problem domain and coming in with a vast amount of preexisting domain knowledge." @tastapod.com Which is why expecting an AI agent to "one-shot" specs is futile. www.youtube.com/watch?v=6mLY...

Just canceled my #claudeCode subscription (I will be able to use it for a few more months, though). Will use #mistral a bit more now - even though it has most of the ethical problems of #GenAI too (*), it's at least European. (*) See smallsheds.garden/blog/2026/on...

Emminently sensible advice from my friend @chrismdp.com who is hardcore into AI coding, has been for a long time. One of the saner voices out there. www.chrismdp.com/coding-with-...

I'm going to be speaking at Agentic Dev Days next week in Stockholm

The new ThoughtWorks Tech Radar reads like a warning letter. Cognitive debt. Broken productivity metrics. Terms nobody agrees on. If you've been reading my posts, none of it will surprise you. It's always nice to get evidence that I'm not completely crazy and making all of this up.

Pleased to see mutation testing and pitest on the ThoughtWorks radar www.thoughtworks.com/radar/techni... As they point out, it's more relevant than ever in the era of AI generated code and tests. And of course the way to use it most effectively on the jvm is www.arcmutate.com #java #kotlin #ai

In short, a programming language is also about the ecosystem and tooling. JAVAPRO has just published the first part of my article series, focusing on the ecosystem. javapro.io/2026/04/16/k...

I worked on an XP team once where we genuinely had 100% test coverage. It was awesome, we could make changes so fast, and yes we still had the occasional live defect

Fans of Spec-Driven Development may believe they've found a kindred spirit in me as they hear me talk about Specification By Example. I'm looking forward to resetting some expectations. Ain't no PRD's or design "phases" in Jasonland.

When it comes to the energy transition I'm a glass half full person. I know: plenty of people would say that's terribly naive. They point to the scale of the challenge. They point to vested interests. They point to hard-to-abate sectors. And they're not wrong. But here's what they miss. 🧵

I updated my personal site! I've been wanting to give it a "proper" design overhaul for years, but the time investment needed meant that I kept putting it off. Thanks to Claude, and to having a bit more "free" time right now, I finally did it! Take a look: trishagee.com

AI agents are writing your test scripts now. So what exactly are you still doing here? If coding was the vehicle but you forgot the destination, you might be getting Pluto-ed. A post about dwarf planets, AI shepherds, and redefining your orbit.

Nice analysis by @kevlin.bsky.social about being a human using ai coding tools. His focus on the engineering and general principles rather the day-to-day tactics. youtu.be/vpYJMr1pJRY?...

NEW POST @birgitta410.bsky.social wrote some initial thoughts about Harness Engineering last month. Since then she's been researching more and has now written a thoughtful mental model for understanding the topic. martinfowler.com/articles/har...

New article where I offer definitions & a mental model how to think about harness engineering as coding agent users. Building blocks at our disposal, dimensions and goals to consider; emerging practices, open questions; and of course, what role do humans play martinfowler.com/articles/har...

Why "bad things" happening is actually the best chance for a development team to learn. This is the story of how a costly mistake taught me a BIG lesson about team culture in software engineering. 📽️ Available on @modernswe.bsky.social ➡️ youtu.be/Q0gxen_uXlw

As a research project, I built a needed tool with Claude Code. I though it would be a disaster, but It wasn't. I have some complicated feelings about it.

This stray thought resonated with people more than I expected so I expanded upon it with a blog post. I came up with five distinct takeaways from the Claude Code leak that have little to do with the actual code quality, and focus more on what this all tells us about building products in 2026.

So good! A wonderful metaphor for what's going on in AI coding today. www.dbreunig.com/2026/03/26/w...

When I published this post I hadn't yet come across Trip's own writeup of the project, which provides way more detail about how he trained the model including SFT (supervised fine tuning) against synthetic chat examples created using Claude Haiku and GPT-4o-mini www.estragon.news/mr-chatterbo...

I really liked this article by @ramtop.bsky.social, and sent it on to some folks in my family who are either technical or technical-adjacent. I also liked the mention of looking after your mental health and not following AI's rhythms outright. Thanks, Uberto! medium.com/@ramtop/proc...

I'm obviously somewhat biased on this one, but yes, it's completely indispensable. Removes a huge amount of cognitive load, gives you a deserved sense of confidence in each change, and helps prevent code bloat. And it's also the only way to refactor a test suite safely.

This talk from Birgitta Boeckeler was my highlight of the Agile meets Architecture conference - really happy to see it made public now. I listened a second time it was so good :-) youtu.be/qB7rsbDfmQg?...

This was great! Definitely eyes wide open about the challenges of software companies, but had some great ideas about metrics.

Coding is dead! Well maybe... the job of a software developer is certainly changing really fast at the moment due to AI tools. This is all very exciting and worrying at the same time. I just wrote this article about what TDD looks like in this new age: coding-is-like-cooking.info/2026/03/test...
