If software development is human communication & two parties are speaking different languages, we regain hope for mutual progress when we realize that we are speaking different languages (even though we use the same words).
@kentbeck.com ’s The Forest & The Desert Are Parallel Universes at GOTO CPH 2025 explored how similar behaviors lead to opposite outcomes - and how to get from crumbs to cake. 2026’s lineup looks incredible.

How I doubled my development velocity with AI:
Not by writing features faster.
By investing in what makes speed sustainable.

Hace 13 años perdimos al hijo de Internet, Aaron Swartz 💔

Con 26 años ya había hecho muchísimo (Reddit, Creative Commons, RSS...).

Perseguido por hacer que el conocimiento fuera accesible y dedicar su vida a la libertad en Internet frente a la dominación corporativa. Hay que volver a ver su docu 👇
Aaron Swartz defendió que compartir libremente conocimiento que podía fomentar el progreso de la Humanidad no era una opción, sino obligación moral. Se enfrentó a una multa de 1 millón de $ y 35 años de prisión por descargar artículos académicos. Se quitó la vida. Su docu archive.org/details/LaHi...

The construction metaphor is killing us. We need to stop "building" and start cultivating—treating code as a living system that evolves, not a finished product.

So, I decided to get my hands dirty and cloned Edu’s augmented coding tools repo: github.com/saski/augmen...
…adding a translation of the FIC Claude plugin, wiring it up as Cursor commands.

I've been asked several times in the past couple of months to recommend a book about "AI"-assisted software development.

This is the best one I've seen so far.

¿Y si no tanta gente como creemos ha trabajado en equipos ágiles de verdad? Con autonomía, end2end, trabajo iterativo y excelencia técnica.
¿Y si quienes sí lo han vivido ya no quieren otra forma de trabajar?
¿Y si ahora se frustran sin entrega continua ni calidad sostenible?

One of the best teams where you could probably work in your life, highly recommended!

And it will probably challenge your understanding of agile/Lean/XP aka "real continuous and sustainable delivery of value" 🫶🏽
