Feb 3rd: At FOSDEM to talk about Nakadi

Back when I was studying in Belgium, I religiously attended FOSDEM – the Free and Open Source Software Developers’ European Meeting, every year, in Brussels. In fact, as a member of the NamurLUG, I was part of the team that recorded the talks at FOSDEM for quite a few years. Initially we recorded with consumer-grade cameras, but we soon upgraded to better quality equipment, and even started streaming the events live, after a couple of years. Since then, another team has taken over, and the quality of the recording has improved quite a lot from our very amateur debuts.

This year, I will be back at FOSDEM, but this time I’ll be on the other side: I will give a Lightning Talk about Nakadi, the Event Broker I work on at Zalando. Nakadi is Open Source Software, and provides a RESTful API on top of Kafka-like queues (we have plans to support Kinesis in the future), as well as a bunch of other features: schema validation with json-schema, schema evolution, per-event type authorization, and more. In this talk I will focus on one of my favourite features: Timelines. What is Timelines? Well, I guess you’ll have to watch my talk to find out (or wait for the blog post explaining it, I am working on one)! If you can’t make it to Brussels for FOSDEM, the talk will be recorded and streamed live.

Some of my colleagues will also speak at FOSDEM, and more will be in attendance. Oleskii Kliukin and Jan Mußler will give a talk called “Blue elephant on-demand: Postgres + Kubernetes” in the Postgres devroom. And Ferit Topcu will talk about “Automating styleguides with DocumentJS” in the “tool the docs” devroom.

See you all in Brussels in February!

Data Natives Panel: Open Source Data Projects in Berlin

Back in November, I was at the Data Natives conference in Berlin, to take part in a panel on ‘Open Source Data projects in Berlin’. The other panelists were Kostas Tzoumas, Co-Founder and CEO of data Artisans, Ines Montani, Founder of Explosion AI and spaCy developer, and Andreas Dewes, Founder at 7scientists GmbH. The panel was moderated by Dr. Kristian Rother, Python Trainer at Academis. I was there, representing Zalando, and in particular my team, that maintains two open source projects, Nakadi and Bubuku.

All of us are involved in open source software development, so it will be a surprise to nobody that we all agreed that open source is a good thing. I guess it’s getting hard to find people that disagree with that statement, these days. Still, our approach to open source software differs. The way we do open source at Zalando, a relatively large tech company, is quite different from the way a two-people consultancy does it.

In our discussion, we had an interesting exchange on a variety of questions, such as the reasons for a company to open source software, licensing, building and managing a community, and many more. The talk was recorded, you can find the video below.

And Now for Something Completely Different

Gone is the static website. Instead, this new blog.

I’m a software engineer, and currently I work on an open source event broker called Nakadi. I’m interested in data engineering, open source software, self-adaptive systems, and authorization.

On this blog I will talk about what I am currently working on, post (technical) book reviews, and updates about talks I attend or even give. And jokes. I have a few posts in drafts to get started with. Then, we’ll see how it goes.
