coding stuttgart: {meetup: {index: 1 } }


coding stuttgart, here's our second (or oneth, if you're still into zero based indexing) meetup. There will be talks, there will be conversation and there will be code for sure. And thanks to our host Turbine Kreuzberg there will be amenities to keep you alive during the evening.

Last time - when we dropped the word "Self Sovereign Identity" - someone stood up and said, "that sounds interesting"! Now guess what: we have found a speaker who's going to give a great talk about it! Kai Wagner by Jolocom (Berlin) will take the opportunity and clear the clouds on how you gain back control over your identity using blockchain technology (and how to integrate it into your applications).

So far, we can announce this agenda:

18:30 doors open

19:00 say hello, warm up and introduce yourself

19:15 talk #1 Kai Wagner (Jolocom): The future of digital identity: self-sovereign identity

Jolocom is developing digital identity solutions using self sovereign identity principles. Kai will explain the main concepts behind it and give some demonstrations on how applications can make use of it. Self sovereign identities are created and managed by its subject (you!) in a completely decentralized manner. Jolocom's protocol allows access rights management for companies, for governmental use cases, for embedded devices and of course for everyone who wants to gain back control on her identity. Everything at Jolocom is open sourced and implemented along open industry standards.

Kai is responsible for partnership development at Jolocom, excited about the potential of open and interoperable infrastructure for the decentralized web and frequently shares his perspective at events and workshops. He's also an active member of the German Blockchain Association (Bundesblock) and contributed as lead author on its SSI initiative (

~ 20:20 Stefan Adolf (Turbine Kreuzberg): How we enabled an IoT commerce use case using api-platform & GraphQL

Building APIs can be madness, especially if you want to do it right from day 1. Uncountable projects support you in this business but api-platform stands out. In this talk Stefan demonstrates the setup of a fully featured api-platform application by merely adding some plain doctrine entities and annotations. The result is a fully interactively documented API service (Swagger) that creates JSON-LD, JSON:API or JSON-HAL compatible inline links. Its Hydra docs enables you to scaffold fully functional frontend clients without writing any code at all, and by adding just one more composer dependency everything unfolds as GraphQL API.

In case you want to give a (lightning) talk, feel free to approach us any time. If you're more on the spontaneous side: you might have noticed that talk slot 2 has been taken by Stefan, one of our organisers :) While he loves to give talks he even more would love to hear yours! So if you've got a great talk and want to give it that evening, feel free to message us soon and grab Stefan's slot for you!


Here are some simple commandments for a good coding meetup and its talks:

- As soon as 1 person is around who doesn't understand German, we switch to English (if you want to give a talk in German, this has to be announced upfront).
- Don't bash one technology in favour of another without giving a *very* concrete reason.
- One demo can spare you 10 slides, so don't be shy and type live – we're all developers, so we'll only laugh at cat pictures and not your code stunts.
- Talks have to be hands on, they must contain at least one line of code and in the best case they're massively supported by demos.
