Introduction to OpenStreetMap

What is it? How can you use it? - Main Talks Room

Are you interested in maps? Are you searching for a FLOSS mapping navigation? Do you need geodata? Do you need a map on your site? Do you want to help creating maps from your local environment or from vulnerable places? Then, you have come to the ...

OpenStreetMap is an open database of geodata and has become the biggest geodataset of the world. It is often called 'the wikipedia of maps' and is getting used in more and more applications - from grassroot movements to big corporations. A tremendous lot is possible, but it can be confusing to get started and to dive into the ecosystem.

In this talk, I'll give a high-level overview of OpenStreetMap and answer the most important questions:

- What is OpenStreetMap (and what is it not?)
- What applications exist?
- What tools exist?
- How can one contribute?
- How can one export data?
- How can one get in touch with the local mapping community?

No previous experience with mapping or GIS needed! This is a talk, so you don't have to bring anything. However, if you need some help with your first OSM-edits, I'll stick around after the talk to get you started. In that case, it might be useful to bring your laptop (or smartphone)

nostr: the real twitter killer?

Notes and Other Stuff Transmitted by Relays - Main Talks Room

nostr: a simple, open protocol that enables a truly censorship-resistant & global social network.

nostr is a new open source protocol, aiming to solve some of the issues of the existing twitter alternatives. Many things can be built on this protocol, but a twitter-clone is the first obvious thing which is being built.

Workshop: An introduction to bondage.

Workshop room 3

Ok, this workshop is not a common for hacker conferences, however, we see a huge overlap between people understanding the mayers of the OSI model, and those that like to experiment in the bedroom. I blame curiosity.

What will this workshop offer?
Glad you asked!

In this workshop you’ll learn all about rope and rope safety, the basic knots you’ll need and how to do freestyle rope play using a range of styles. You’ll have loads of fun and laughs while learning. We dare you to finish without a big smile on your face!

People are encouraged to join, with or without a partner, you don't need rope.
Please show up in time, latecomers will have to wait another year.

A Gentle Introduction to Nix

Workshop room 1

During this talk, Bryan will touch on the following subjects:
- What Nix (the project) is
- Why this is a good idea
- How to read Nix (the language)
- How to use Nix (the package manager)
- What NixOS (the operating system) is
- Where to ask...

Do you have a colleague or friend that just can't stop talking about Nix? How it's reproducible, the future of software. Why it's so much better than the other tools out there. He just won't stop talking about it. And now, you've given in. You decided to give it a try, but where to start?

If the above is you, this talk is for you! Bryan will give his best attempt at giving a gentle introduction to Nix. After this talk, you hopefully understand Nix's values, and where to find more help if you happen to need it.

So Many Trackers in your Pocket

Many Mobile Apps contain trackers, pieces of programs that track your behavior and send it to advertising companies and "data brokers".

In this talk, we will see how NetGuard [1] exposes all these trackers, before you had any chance to give your consent for being tracked (which is required by the RGPD, and therefore illegal). We will look at the diversity of trackers included in many popular Apps, how to evaluate how bad an app is using Exodus Privacy [2] and discuss a few ways to protect your privacy against these unlawful behaviors.

Move fast & build things

An intro to Aetherspace, the framework for Expo, Next.js, and Single sources of truth - Main Talks Room

40-min talk exploring Aetherspace and how it can answer what it would take to compete with the likes of Elon Musk.

From how to build for web and mobile from the start, to how single sources of truth and automatic docs generation can help individuals or smaller teams move fast and build things. In this 40 minute talk, we'll explore this thing I created named 'Aetherspace'. It's a sort of "meta-framework" for what I like to call the GREEN stack, namely: GraphQL, React-Native, Expo, Evergreen components, and Next.js

Both the talk, stack, and Aetherspace cover these topics:
- Building for browsers, servers, iOS and Android
- How single sources of truth can help
- How to keep it all write-once with React-Native, Expo, Next.js

If you've had an idea and you're looking to build a web and/or mobile app for it, this will be the talk for you.

Cyanotype workshop

Workshop room 2

Learn how to make your own cyanotype prints at home!

The cyanotype (or blueprint) process is one of the first practical ways of making a photographic print. In this workshop, you will learn the history of the process, what materials you need, and how you can do it at home.

Participants should come with either a digital photo that they want to print, or an idea of what they want to take a photo of.

Additionally, we ask that participants bring €10 to cover the cost of materials.

The full process takes about an hour and a half, but the middle hour of that is waiting for the film to develop and dry, so it's perfectly OK to leave for a talk in the middle.

Avoid the Kube headache, go Nomad

Kubernetes on the streets, Nomad in the sheets - Main Talks Room

Making biospheres

We will make nice little biospheres in mason jars. - Workshop room 3

Nice and easy workshop about making a small water based biosphere. It's basically a closed aquarium that does not need maintenance.


Before we go outside to fill our jars, I'll explain a bit about what (not) to do.

After that we go outside to find some body of natural water (pool/river) to fill our jars. (I'll bring 10x >=1000ml mason jars, but if you want to, bringing your own jar makes it certain you can participate if I run out of jars.)

After filling them up we will walk back and look at what we caught!

Although the workshop is basically free to join, a donation is appreciated as I bought all them jars.
