Reactive IoT
IoT is a prime use case for the Reactive principles. With so many connected devices, scalability and resilience need to be built in the system from day one. I am very excited to have Johan Stokking from The Things Network showing us how they achieve these goals. I tinkered about with them around 3 years ago and I'm very curious to see how this incredible project evolved. After that, from global to your house! Find out how to build a DIY smart meter, thanks to Scala, Akka and Maarten Mulders! This meetup is kindly sponsored by Trifork and the GOTO Berlin conference! (https://gotober.com) 17:30: doors open 18:00: pizza & drinks 18:30: intro 18:45: Talk #1: Going Industrial with LoRaWAN 19:00: short break 19:10: Talk #2: Outsmart your smart meter with Akka 19:50: further drinks and networking Talk #1: Going Industrial with LoRaWAN Low-Power Wide Area Networks such as LoRaWAN and NB-IoT seem the perfect fit for IoT devices, combining low power consumption and kilometers of range. However, they come with constraints, bandwidth is limited and communication is uplink focused. This talk, by the CTO of the largest world-wide LoRaWAN network, covers the challenges and opportunities of using LPWAN networks for industrial use cases: focusing on reliability and deployments that will last. Speaker bio: Johan Stokking Tech Lead and co-founder of The Things Network, an open, crowd sourced and decentralized IoT network. Starting with covering the city of Amsterdam in less than six weeks, the community counts more than 46K developers in 97 countries and 4500 gateways connected: the biggest global LoRaWAN network. As CTO of The Things Industries, Johan oversees architecture, product development, operations and is involved in technical business development and customer engagement. Talk #2: Starting 2014, all Dutch households are receiving a "smart meter" to replace their old meter systems for electricity and gas. They're called "smart", but are they really? Most meters just send their data to a central point using GPRS. Using third party services, consumers can get an insight in their energy usage. But we're technicians, we can build something better ourselves. All it takes is a prefab cable (or some soldering), code, patience and a beer. Using Scala plus Akka for the backend, TypeScript plus React for the frontend and Websockets for communication you can build your own energy dashboard. En passant, we might even see a little Akka stream dropping by. Attend this session to discover how to outsmart your Smart Meter! Speaker bio: Maarten Mulders Enthusiastic architect, senior developer and trainer. Passionate about "building the right thing" and "building the thing right". Focusing on lean and elegant solutions. Love to share new ideas and knowledge. Outside work, I appreciate creating and consuming good food, photography, and music, in no particular order.

    What we're about

    We build systems that are elastic and resilient through message-driven architectures, in order to give users a responsive experience. This is the definition of a Reactive system, where what matters is the interaction of all moving parts. At a local level, say a single feature or a single isolated functionality within a service, Reactive Programming is about applying logic as a reaction to the availability of new data. This meetup wants to bring together all aspects of our Reactive knowledge.
