- Remote Development made simple with DevPod (2025-02-02)
-
I come relatively late to the subject of Remote Development Environments (also known as Cloud Development Environments). The main reason is that I haven’t worked in a development team for over six years. However, I’m now working for Loft Labs, and we have a RDE product: DevPod. I wanted to understand our value proposition as I’ll be at FOSDEM operating the DevPod booth. The problem As a former developer, I vividly remember the pain of setting up each developer’s develo[…]
- On inheritance and subtyping (2025-01-26)
-
Java is the first language I learned in my career. Its structure is foundational in my early years of understanding programming concepts. After going through several other languages with very different approaches, I’ve widened my point of view. Today, I want to reflect on the idea of inheritance. Inheritance in Java In Java, the idea of inheritance is tightly coupled with the concept of subtyping. Subtyping is the implementation of a IS A relationship. For example, the Rabbit class is a[…]
- My first steps with Playwright (2025-01-19)
-
In my previous company, I developed a batch job that tracked metrics across social media, such as Twitter, LinkedIn, Mastodon, Bluesky, Reddit, etc. Then I realized I could duplicate it for my own 'persona'. The problem is that some media don’t provide an HTTP API for the metrics I want. Here are the metrics I want on LinkedIn: I searched for a long time but found no API access for the metrics above. I scraped the metrics manually every morning for a long time and finally decided to au[…]
- Practical introduction to OpenTelemetry tracing @ rheinJUG - Java User Group Düsseldorf
-
Tracking a request’s flow across different components in distributed systems is essential. With the rise of microservices, their importance has risen to critical levels. Some proprietary tools for tracking have been used already: Jaeger and Zipkin naturally come to mind. Observability is built on three pillars: logging, metrics, and tracing. OpenTelemetry is a joint effort to bring an open standard to them. Jaeger and Zipkin joined the effort so that they are now OpenTelemetry compatible. In this talk, I’ll describe the above in more detail and showcase a (simple) use case to demo how you could benefit from OpenTelemetry in your distributed architecture.

- WebAssembly on Kubernetes @ JCON
-
WebAssembly started as a technology tailored to web browsers and is becoming popular as a server-side technology as well. The next step is for Wasm to become a powerful tool for cloud-native applications. When combined with Kubernetes, WebAssembly can revolutionize application deployment, security, and resource efficiency in ways traditional containers cannot. This talk explores why and how to leverage WebAssembly within Kubernetes environments to create scalable, high-performance, and secure applications.
