Many of the software engineers I talked to told me that they practice TDD out of guilt. That's not right, we need a different way to think about TDD. I've been practising TDD for almost a decade, here's how I currently think about it:

How does motivation differ when helping agents versus helping humans, including oneself?
Andrew Cairns
@andrewcairnsFeb 22
What makes our agents write better code is... ... what has helped us write better code. For decades. Timeless principles are holding up pretty well, I'd say. If you'd like to know more about Composition over Inheritance, I made a video: youtube.com/watch?v=HNzP1aLA…

Decompose or die trying.

Agentic coding strongly favors working in smaller slices and moving each slice through the product discovery, development, and feedback cycle at a much faster rate Writing code faster just shifts the bottleneck to the rest of your product development process—you need to optimize the entire thing

Comfort compounds weakness. Stress compounds strength.

Comfort is seductive because it feels harmless, but it quietly compounds into weakness

I can't believe my last tweet was back on June 2024! Thinking to get more active again to process my thoughts here. Who is still around?

Better problem understanding leads to better design. This technique from @ericevans0 helps achieve exactly that. read.ceilfors.com/p/concrete…

Done. Handing @laconiajs over to someone else feels like I'm handing over my child to someone else. It's odd. My biggest reward from this work is the opportunity to work with the loveliest and smartest people in tech @marton_veto @thomasankcorn @tschoffelen!

Has any of you built an open-source project and gotten it adopted by a company? I'd love to know what important things you'd typically look at from the original creator/maintainer's point of view.

The solution is simple. Don’t mock what you don’t own. Introduce your own interface and mock its behaviour. Write a contract test for the implementation of the interface. The contract test should actually call the API and at least confirm mocks’ assumptions. – at Bexley, London

The risk with mocked tests: The test may not test anything. Example: I just reviewed a test that claimed to ensure a JSON API response was the expected shape. The problem: The test mocked the API response. So the test didn't actually test anything.

Been playing with @microbit_edu, 7yo was super engaged with it! She did 90% of the code.

You don't need to be a mathematician to do good math. You don't need to be an engineer to write good code. You don't need to be a leader to provide good leadership.

Been experimenting with Structurizr again recently. Found it hard to get started (various little DevEx and UX issues), but gets easier once you get used to it. Love what I'm seeing now!

I did spend a couple of hours figuring out how to piece everything together to discover that what I need is on this page: docs.structurizr.com/product… @simonbrown is it worth linking this page from the Quickstart page? My use case was I immediately wanting to use the cloud service.

I was also trying to get the cloud service to show plantuml/kroki images via their public services and hit the documented CORS issue. Could be nice for Structurizr Cloud to have its own plantuml or kroki server to make this seamless?

This bias happens over and over again to me when I'm delegating. Tasks I thought I didn't like I shouldn't delegate, because others wouldn't like the task either.
