Is TDD with AI just "theater"? 🤖 @emilybache.com breaks down why prompt-only coding fails and how realistic harnesses & TDD discipline make AI code reliable. Join her FREE live webinar on Nov 12! 👇 www.subscribepage.com/eb-webinar

At least this developer struggle has been replaced by AI... 😅

"TDD is actually easier than writing the tests afterwards, so why is it so hard to learn?" - @emilybache.com What are your thoughts? 👇

AI won’t replace software engineering, it changes the economics of writing code. But prompts aren’t enough. To safely guide AI agents, we need executable specifications. Discover why Acceptance Test-Driven Development (ATDD) is the future of AI coding. 📽️ youtu.be/EkH_uoybj8k

For us software engineers, where does development end, and engineering start, in your opinion? 🤔

"Simple is a function of Now." — Daniel Terhorst-North Simplicity in software engineering isn't a static target. Code that is perfectly simple for today’s constraints can become a bottleneck tomorrow as requirements shift.

Collaborative coding in an ensemble or mob has been a cornerstone of my work, and when you add agentic AI it needs different interaction patterns. My latest video and blog explain some of the things I've found to work. youtu.be/ydAin2IWaQo & coding-is-like-cooking.info/2026/10/agen...

Now for a quote Jurassic Level Big Up to @modernswe.bsky.social for their YouTube note. Approval testing, too, is a healthy technique to monitor throughput, yet the note invites questions: 1) Can Approval Tests be synthesized with adequate *other* layer tests? 2) When does trunk time start?

Think legacy code is just old Cobol programs? Think again. The untested code you committed this morning might already be legacy. In my new video, I explore why legacy isn’t about age, but about testability and the cost of change. Watch now on @modernswe.bsky.social ➡️ youtu.be/jScItKhruN0

"I bought this book for myself after watching Dave Farley's YouTube channel. I've now bought a second copy for the office library and I'm suggesting that everyone in my development team reads it." Why thank you! 😎 Grab your copy here 🔗 amzn.to/3DwdwT3

Inheriting legacy code feels like a minefield. Approval testing records system output so you can refactor safely without breaking existing behavior. Want to learn how? Grab Dave Farley's FREE Approval Testing Guide 👇 www.subscribepage.com/approval-tes...

Inheriting legacy code without tests feels like walking through a minefield. You know it needs refactoring, but you're terrified to touch it because you don't know what subtle behaviours might break. 🧵 1/4

The data shows that the fastest-shipping engineering teams are also the ones delivering the highest quality code.

Pushing your dev team harder for speed actually slows you down. In tonight’s new video, I explore why software isn't a factory production line, it’s a discovery process. Stop rushing delivery & start optimising for learning.123 Tune in tonight at 7 PM! On @modernswe.bsky.social
