@laventana ¿Cuál es el nombre del libro del que estáis hablando? Gracias!

[Richard Seroter @rseroter]

We've all designed some bad software before. Just me? Ok.

@arrayexception calls out for signals that you've got a suboptimal design—think rigidity, fragility, immobility, and viscosity—and what to do about it.

Son lo suficientemente fuertes como para caer al suelo ordenadores, bolsos, etc., desde las mesas de los asientos.

Hace pocos minutos ha ocurrido en el tren en el que voy.

@Renfe @Adif_es sólo quiero comunicar que el tramo de vía entre la estación de Segovia-Guiomar y Valladolid tiene múltiples tramos en los que el tren Intercity, destino Ponferrada, sufre sacudidas muy fuertes.

No son el "bamboleo" del tren.

@simyo_es ¿Alguna previsión de cuándo se va a restaurar la línea de internet en las zonas afectadas? En mi caso, llevo sin internet desde las 13:35 de hoy , más o menos. Gracias.

An incremental architecture is an architecture designed to grow.

And why this is something you should care of? 👇🏽

[Marcos F. Lobo 🇺🇦💙💛 @[email protected] @arrayexception]

This is a fact 👇🏽

Cross-functional teams deliver faster than layered organizations because each team owns a domain end-to-end. No waiting for “the backend team” or “the frontend team” to free up a sprint.

People leave companies because:

🟢 Money

🟢 Stability

🟢 Work respect

Fruits, candies, retro-game machine, and apéros after work are just smoke bombs.

Folks, I've just published another learning about how make software Architectures Incremental.

I would love to hear your thoughts about it 👇🏽

In this email, I just wanted to make a heads-up about Crossplane, a technology that solves a real and important problem that the majority of us suffer from every day:

👉🏼 Not owning our infrastructure.

Are you into some certification?

🟢 Is it worth it?

🔴 Or better to pass?

I read you in the comments 👇🏽

If you want, I can share a checklist and commands to spin up the POC in 10 minutes with Promptfoo.
You can run it today and present results in your next sprint demo.
Interested?

You can now own your infrastructure without opening a ticket.

Practical idea: define 5 representative prompts, run them with 2 models and 2 data domains.
Measure accuracy, format correctness, and tokens.
If just one combination performs clearly better, you’ve already saved time and money.

Useful tools to kick off your POC:
Promptfoo for CI testing, LangSmith for traceability, and OpenAI Evals for programmable cases.
Start with one tool and measure. Then decide if building something internal makes sense.
