@alejandro_mro @BettaTech Sacar provecho a métricas y traces para bajar la logs dependencia
A Coruña, Spain 🇪🇸 Español

@BettaTech Pues primero tener claro QUÉ consideramos relevante logear. Si aparece en el log, es porque hemos decidido que es relevante. Si los logs son "demasiado ruidosos", es porque percibimos que hay logs que no tienen valor. Luego pensar en formatos de los logs según severidad.

The most helpful Java pattern for writing safe, maintainable code: Sealed Result + Pattern Matching
One of the best ways to improve code quality and reduce bugs in Java is to stop using exceptions for expected business cases.
Instead, use a sealed Result type + exhaustive pattern matching.
Why this is very helpful:
Compiler forces you to handle every possible outcome No surprise RuntimeExceptions in production Self-documenting return type Much easier to test and refactor
Realistic example below:

- Meet James Gosling
- Creator of Java
- Built his first computer from scratch as a teenager
- Loved math, science, and tinkering with electronics
- Preferred experimenting on his own rather than traditional classroom learning
- joined Sun Microsystems and noticed a major problem
- Programming languages were complex, unsafe, and hardware-dependent
- Code couldn’t run easily across different machines
- Many projects failed due to system incompatibility
- got Frustrated with these limitations
- Created a new language called “Oak”
- They wanted simple, catchy, and energetic name
- The team was drinking coffee during brainstorming ☕
- so Later they renamed it to Java
- he wrote the original Java compiler and virtual machine himself
- designed it to be Simple, Secure, Platform-independent
- it became one of the most influential programming languages in history
- Widely used in: Web applications, Android apps, Enterprise systems, Banking software
- Adopted by millions of developers worldwide
- earned the nickname as “Father of Java”
- literally changed how software is built across the world.
Absolute legend.

Cada vez que el “Clúster” y su presidente, Cesáreo Pardal, abren la boca, no hacen más que confirmar lo alejados que viven de la realidad.

Answer generation and search are related albeit significantly different use case cases, demanding fundamentally different architectures.
From time to time, I will use an LLM for answer generation, but every time I will verify its results.
I also presume that search will always be biased and inadequate, and I act accordingly.
Do not surrender your humanity to tools that are architecturally and demonstrably unreliable narrators.

@vladikk Hi Vlad. Totally agree! Your book is a game-changer for anyone looking to level up their problem-solving skills. Can't wait for an updated edition 😊

AI can write code. Time we agree on that. But software engineering isn't about code: it's about solving problems. Some problems are trivial, but the interesting ones don't have trivial solutions. They require experimentation, risk taking, and even pivoting. That's why the AI era is the third coming of Domain-Driven Design. The ability to analyze and communicate problems effectively is a strategic superpower now more than ever.

And what do we call a thing that is expressive and precise and deterministic and repeatable so as to produce reliable executable artifacts?
We call it a programming language.

VENEZUELA CAMPEÓN MUNDIAL DE BÉISBOL
Nuestras felicitaciones al pueblo venezolano por el merecido triunfo de su novena en el Campeonato Mundial de Béisbol
El equipo demostró talento, capacidad, voluntad, fe y nunca dobló las rodillas, a pesar de haber estado en desventaja.
Esperamos que la siguiente felicidad sea el fin de la dictadura que hoy oprime a la noble Venezuela.
Rubén Blades.

¡Gracias por compartirlo, Alex! Solo un apunte: además de universitarios y recién graduados, hay muchísimo talento en FP (DAW/DAM/ASIR), bootcamps y gente autodidacta. De hecho, la oferta ya contempla “experiencia equivalente” y anima a aplicar aunque no se encaje al 100%. Yo soy autodidacta y llevo tiempo usando Stripe: he integrado Stripe en varias aplicaciones. 🙌
Thanks for sharing this, Alex! Quick note: there’s a lot of great talent beyond university grads—vocational training, bootcamps, and self-taught engineers too. The listing already mentions “equivalent work experience” and encourages people to apply even if they don’t match the description perfectly. I’m self-taught and I’ve built multiple apps using Stripe. 🙌

El mayor de los éxitos a la Selección de Venezuela 🏀 en el inicio de los clasificatorios al Mundial de Qatar 2027 @FIBAWC.
Eliminatoria difícil por muchas circunstancias, pero así mismo con oportunidades que, si se aprovechan, pueden cimentar el futuro. El viaje es el destino. Vaya!

Important note:
Your SLA should align with a percentile, not the average.
If you promise “99% of requests under 500ms,” that’s a p99 commitment.
If your SLA is based on p50, you're optimizing for the middle while ignoring the tail where outages and churn happen.
Always design capacity, retries, and timeouts around p95–p99 behavior, that's where reliability is decided.
