On tonight's episode of I Couldn't Be Bothered To Even Google It, "TDD assumes that all the design work has been done in advance"

Use the answers to those questions to find a better name: - VehiclePerformance - VehicleRegistrationRequest - VehicleUsageHistory The insights gained will often lead you to different abstractions in your code. It's a virtuous cycle. 2/2

Whenever you see programming terminology in your domain model, it's a sign that there is probably a missing domain concept. For example, variables and classes that contain the name "data" like VehicleData. What does that data represent in your domain? How is it used? What purpose? 1/2

Current state of the industry

Vaya, y yo pensando que el gobierno no puede gobernar porque... porque... Anotop at. 😏

When I hear that a practice defines culture, I snap. Practices don't define culture. It's vice versa. "You don't have a product trio, so you don't have a product development culture" confuses correlation with causation. pawelbrodzinski.substack.com/p/product-tr...

What if the real key to getting better results with AI coding agents is boring stuff from the 1990s? Would it help if we called it "feedbackmaxxing"? codemanship.wordpress.com/2026/05/28/w...

Software engineers will replace AI in 6-12 months (in software modernization projects)

One thing you learn the hard way from running a business is that the only meaningful kind of market feedback is paying customers. "I'd definitely buy that" does not, in reality, mean that they will buy it. Consumer behaviour can only be observed in the wild.

El problema es que entre tanto bulo y prevaricación para derribar al PSOE, el día que aparezca algo verdadero, no lo distinguiremos de la realidad y nos comeremos otro "ni de Flick ni de Flock". 😒

If you have an exceptionally strong, automated CI pipeline with TDD and great test coverage, why are we still relying on asynchronous, manual gatekeeping instead of practising true continuous integration directly on the trunk? 🤔

Madrid, la comunidad más rica de España, introduce un copago a enfermos de ELA pese a los 500 millones transferidos por el Estado. Hemos aprobado ayudas de hasta 9.850€ al mes y pretenden que los pacientes paguen de su bolsillo el 40%. Este es el modelo de Ayuso.

Más de dos años de arrastrar el nombre de alguien por el lodo y con ello pretender que caiga un presidente y con él un gobierno, por parte de un juez, por parte de medios y por parte del PP, VOX y demás patulea derechona… y ahora sale esto. Si la justicia y la investigación es lenta, no es justicia.

People who deny the existence of dragons are often eaten by dragons. From within.

A great way to adopt patterns for AI coding is to apply reusable agent skills. The Chiron Codex agent skills repo now has 13 skills you can use to support the interaction patterns for AI-Augmented Software Development: codeberg.org/leeg/chiron-...

News: OpenAI had a negative 122% operating margin in Q1 2026, and ChatGPT growth has stalled. Based on its current trajectory, OpenAI is on course to lose over $36 billion in 2026. www.wheresyoured.at/news-openai-...

Going AI-first without solid engineering foundations is a bad idea. It should be foundations first, AI last. Otherwise you'll never find the time to build them, and the engineers who could help won't look at you twice.

Lately there is so much noise about "Agile is dead because AI" So to replay once and just share always the same link: emmanuelvalverderamos.substack.com/p/ai-does-no...

I recently heard someone say that the challenge with "left-shifting" in testing is that end-to-end tests take too long to run.

The evolution of my substack is interesting, I never thought about reaching more than 3 people hahah, but I'm happy to see that is growing

Therefore, by placing architectural description records as artifacts within a repository, you have a wonderful strange loop: the architecture is represented by multiple views, one of which contains a description of the entire architecture, including itself.
