Naresh Jain has long been uncomfortable with software patents. But a direct experience of patent aggression, together with practical constraints startups face, led him to resort to defensive patenting as as a shield in this asymmetric legal environment.

There's been much talk about how AI agents affect the workflow loops of software development. @kief.com focuses on the goal of turning ideas into outcomes by building and managing the working loop, rather than leaving the agents to it or micromanaging.

my immediate reaction is "how do you measure design quality?"
But the feedback I'm hearing is that iff you are careful with your prompting, you can get decent code out of them these days.

Rahul Garg uses a structured conversation with an AI agent that mirrors whiteboarding with a human pair: progressive levels of design alignment before any code, reducing cognitive load, and catching misunderstandings at the cheapest possible moment.

And if you enjoy podcasts, do have a listen to the 99% invisible series on The Power Broker. It's a great accompaniment to the book
Yes, got through the LBJ ones. I enjoyed how #3 reveled in his senate maneuvers, particularly the passing of the, admittedly hollow, civil rights act. The fourth has great portraits of the Kennedys and his description of the day of assassination is totally gripping.
My reading this year was dominated by Robert Caro. The books are huge, but so worth it. martinfowler.com/articles/202...

Rahul Garg sees a frustration loop when working with AI and identified five patterns to help. Here's the first: priming the LLM with knowledge about the codebase and preferred coding patterns.

The concept of Servant Leadership has never quite sat properly with me, because it's essentially gaslighting. Recently I came across Host Leadership as a better framing.

I've heard a number of reports recently about people setting up LLM agents to work on their email and other communications. I think this is extremely risky

@birgitta410.bsky.social explains why OpenAI's recent write-up on "Harness Engineering" is a valuable framing of a key part of AI-enabled software dev. Harness has context engineering, architectural constraints, and garbage collection of the code base.

Thanks for noticing the error, I've let Birgitta know and I'll post a fix when I have it,

Powerful context engineering is becoming a huge part of the developer experience of modern LLM tools. @birgitta410.bsky.social explains the current state of context configuration features, using Claude Code as an example.

These days I'm seeing a lot of bold fonts, especially in LLM-written prose. But when bold is used frequently, it quickly becomes ineffective.

Erik Doernenburg maintains CCMenu: a Mac application that shows the status of CI/CD builds in the Mac menu bar. He assesses how using a coding agent affects internal code quality by adding a feature using the agent, and seeing what happens to the code.

I had a conversation with Unmesh Joshi, and Rebecca Parsons where we talked about the feedback loop between the "what" and "how" in software development, and the role LLMs play in it.

Jim Highsmith sees teams turning into tribes wedded to adaptation or optimization - but we should manage the tension between them by blending modes of explore and exploit, based on uncertainty, risk, cost of change, & evidence threshold.
