Cómo crear una constelación de software 🚀 La historia de Constellation Software

¿Cómo se puede gestionar un grupo de 500 empresas, 50.000 empleados y 50.000 millones de capitalización bursátil con unos servicios de... 14 empleados? 😲 La historia de Constellation Software, vía #bonilista app.supermo.no/share/eed035...

One day the industry will recognize the drawbacks of AI agents and nondeterministic automation, and rediscover the UNIX philosophy of chaining together small purpose built tools in a low cost and predictable way, otherwise known as shell scripts.

Hoy en FredCon 25 compartí la charla “Incentivos perversos, resultados previsibles: Cuando el sistema sabotea a los equipos”.
Cómo el Taylorismo aún sabotea a nuestros equipos y qué podemos hacer para cambiar el sistema.

🏆 100 Most Watched *Java* Talks Of 2024 A complete list of the top 100 Java talks of 2024 ordered by the number of views.

Wooow, I made it to the top 100 of #Java talks in 2024, position #43 for "SpringBoot ❤️ Testcontainers" 🥳
It was the only talk I did outside of Spain last year (at Voxxed Days CERN)

The only sustainable way to go faster is by avoiding waste. Learn, adapt, and improve. #software #agile #lean #continuousimprovement"

The fastest code is the code that is never executed. Be brave, and remove the unnecessary. If a feature is not used, delete it. #CodeDeletion #Simplicity #SoftwareDevelopment

Great article. Very instructive. A clear example of the practical use of the Lean principle of defer commitment, working in small steps, always focusing on making the system as simple as possible for current needs (as a strategy to continuously evolve it as needed...).
