Every year, manufacturers produce 1.5 billion smartphones worldwide - and unfortunately, probably just as many are thrown away after what is usually a far too short hardware lifespan. E-waste increases every year. The energy required to produce the devices is extremely high, and the manufacturing and supply chain spans the globe several times. With Upcycling Android we address the problem by extending the hardware lifespan of phones and Android devices in particular!

With this workshop we want to give everybody the opportunity to flash a custom ROM to a device. We will provide some devices to flash and a live system with all needed parts installed. If you want to try out flashing a device, please bring your own notebook (with 8G or more of memory).

You can find more information about Upcycling Android on the FSFE website.

The Fediverse is a decentralised social network. But what does that mean?

In this talk I will give a short introduction to the Fediverse of 2025 and how it started to evolve in 2008. I will explain the basic concepts of ActivityPub as the protocol of the Fediverse and how the use of this open protocol has enabled a diverse group of Free Software projects to build a social network of (micro) blogging, video streaming, podcasting and event organizing. A network of thousands of community hosted services, where users can share and interact with each other regardless of the platform they use. What is possible in the Fediverse of 2025? And how can you get started today?

This talk does not require any technical knowledge of the Fediverse. However, you should know what an email is.
