Refactoring is how we keep complexity under control, protect our design, and maintain the ability to deliver at speed without sacrificing quality.
This is why we’ve invested so much effort into helping devs and orgs build refactoring skills & confidence.

The teams that move fastest, with the fewest defects, are the ones that continuously improve the structure of their code.
The truth is simple: if your system is hard to change, you're already in trouble.

Refactoring isn’t optional in modern software engineering. It’s the economic engine of healthy codebases.
Organisations that treat refactoring as a luxury end up paying for it twice: first in slowed delivery, and later in firefighting and reworking...

I am working on a video for my YT channel. I am musing on the idea that knowledge of assembly level programming informs how we think about how computers work. I feel that my knowledge deeply informs how I interpret how things work, but I am struggling to find a killer example, any suggestions?

The green lights are passing tests, the signal that your code is safe to move forward.
That’s the rhythm of Test-Driven Development. By embracing the red–green cycle, you create a flow where each release moves forward smoothly, with fewer stops and surprises.

At times, software development can feel like getting stuck in traffic, constantly being held up when all you want to do is move forward.
In this metaphor, your software is the car. The red lights are failing tests, the bugs that stop you in your tracks.

I haven't seen anyone do that, but it is, a simpler translation problem than general natural language translation, because the grammar of the DSL is so constrained and so much simpler than human language. I imagine a map of translations for each function call, and the name of each param in your DSL.

I think AI can help with Approval (aka Characterisation Tests) where the goal is to demonstrate that the code still does what the code did before.
Essential to support refactoring, but doesn't tell you if the code does the right things, so not so useful for new development.
