I gave Quarkus two event loops and fired 24 requests at it at once. Every one was served by one of those two threads. Part one of a series on how Quarkus runs your code, starting below Quarkus: Netty, Vert.x and the rule you cannot break.
I found beans in my application鈥檚 bytecode that no class in the project declares. In part 3 of this ArC deep dive, I show how extensions create beans from configuration, why Quarkus doesn鈥檛 run Portable Extensions and how a Quarkus extension works inside.
A constructor that runs twice, an interceptor that works even on internal calls and a bean that doesn鈥檛 even exist at runtime. In part 2 of this ArC deep dive, I show what the Quarkus build changes in application code.
I opened the bytecode Quarkus generates for CDI to see what the container does before the application starts. Part one of a deep dive into ArC with real experiments: discovery, validation and a create() that is just a new.
Writing code fast stopped being a differentiator. Here鈥檚 what actually sets engineers apart in 2026: from century-old advice by Carnegie and Covey to technical judgment and public visibility.
Want to contribute to Open Source but freeze before you even open the editor? Documentation and translation are the easiest door in, and you can ship your first PR today.
An ordinary Monday morning, no stage and no audience, I found out I鈥檇 reached 10th place among the contributors to quarkus-langchain4j in the world. The story of how I got there in 5 months, and what changed along the way.
What virtual threads solve, what they break, what happens when your database slows down, and why Java 25 made all of this far simpler than it was in 2023.
How structured note-taking with Zettelkasten became the memory layer for my AI agents, and how it saves me tokens, time and money.
Part 2 of 2. One browser click crossing five systems and four languages in a single trace, and what changes when that goes to production: tail sampling, cardinality, exemplars and SLOs.
