• Rust in the IoT (Meetup #36)

    codecentric AG

    This talk provides a first introduction to the increasingly popular, machine-oriented programming language Rust (https://www.rust-lang.org/), which has started to challenge traditional approaches such as C, C++ or Go. The talk is structured as follows: After a short introduction, Rust’s essential language features and special features will be presented. We will also discuss extensibility with regard to the module system and the Package Manager, followed by an introduction to the tooling, the community and ecosystem of Rust. Aspects such as available documentation and a short example of an implementation of a multi-threaded web server will cap off the presentation. The focus will be less on theoretical knowledge transfer (aka "slide battle"), but on practical approaches including examples where possible and useful. ***GERMAN*** Der Vortrag bietet einen ersten Einstieg in die immer populärer werdende, systemnahe Programmiersprache Rust, die traditionellen Ansätzen in diesem Umfeld wie C, C++ oder Go immer mehr denn Rang abläuft. Der Vortrag gliedert sich wie folgt: Nach einer kurzen Einführung werden die wesentlichen Sprachmerkmale und die Besonderheiten von Rust dargestellt. Diskussionen der Erweiterbarkeit im Hinblick auf das Modul-System und den Package Manager schließen sich an, gefolgt von einer Vorstellung des Toolings und der Community / des Ökosystems von Rust. Aspekte wie verfügbare Dokumentation und ein kurzes Beispiel einer Implementierung eines Multithreaded Webservers runden Vortrag ab. Der Fokus liegt hierbei weniger auf der theoretischen Vermittlung von Wissen (aka „Folienschlacht“), sondern auf praktischen Ansätzen inkl. Beispielen, wo möglich und sinnvoll. ***Speaker*** With more than 30 years of free and open source software experience, Dr. Christoph Zimmermann is one of Germany’s industry veterans in this field. In addition to his various community support activities including package management for a popular Linux distribution, serving on the board of a Linux User Group in addition to frequent speaker engagements at events such as Chemnitzer Linux Tage, OpenRheinRuhr, etc. he is looking after the user base of the popular in-memory database Redis for the German-speaking countries both as a community liaison and pre-sales consultant.

AGENDA 6 pm: Doors open 6:15 pm: Lightning talk #1 6:35 pm: Lightning talk #2 6:55 pm: Lightning talk #3 7:15 pm: Break 7:30-8:15 pm: Panel discussion, Q&A 8:15- end: Pizza & Networking Technologies presented: Apache Cassandra You maybe heard of companies like Apple, Netflix or Ebay. They own the largest Cassandra deployments in production. Apple's cluster is one of the largest with 75000 Nodes holding over 10 PB of data and Netflix is processing over 1 trillion requests per day. But what is the technology behind those clusters? I like to give you a short dive into the technology, explain some use cases I solved with it and discuss about your challenges and opinions. IoT in MongoDB Sensor-enabled objects are unleashing torrents of data previously unimaginable. Production lines to patrol cars to pacemakers. New revenue beckons. But sensor data is only useful if you can do something with it. With MongoDB, you can make sense of sensor data, building applications never before possible. Faster. With less money. Redis Since its first source code commit just over ten years ago, Redis has managed to become one of the most popular open source databases. Due its tiny footprint, lightning-fast performance and linear scalability it’s rapidly becoming the database of choice for IoT and embedded use cases which need real-time performance from their data stores. After a brief introduction to Redis as an in-memory multi-model database, the talk provides an in-depth discussion of this new offering by using several IoT use cases. SPEAKERS Apache Cassandra Dominique Rondé is a big data pilot and an employee of the InsureTech startup freeyou. He works with all sorts of technologies around the topic of "big data". However, most of his "flying hours" he has collected on the Apache Spark, Confluent Kafka and DataStax Cassanda. In everyday life, he also deals with the possibilities of statistical analysis - in short, data science. As a true Java nerd since 2002, he writes the code of most of the jobs himself and runs them on cloud architectures. MongoDB Ewgeni Hersonski (Senior Enterprise Account Executive) Ewgeni is passionate about technology & disruptive use cases. As one of the very first local sales people in Germany (2015) for the market leader in NoSQL, Ewgeni has contributed towards the early customer footprints at MongoDB in Central Europe with some prominent customer stories. Marc Martin (Sr. Solutions Architect) Marc is passionate to enable companies to run their data driven applications in an efficient way to improve user experience and lower cost. He has 10+ years experience in managing applications and infrastructures. Before he came to MongoDB as a Solutions Architect, companies like Cisco AppDynamics, Riverbed and Compuware benefit from his broad experience. In addition he is a regular contributor within the user communities and an experienced speaker at user groups and conferences.

The recent range of smart speakers and voice assistants is only the start on the way to voice enabled anything. In the talk, the components and building blocks of speech interaction systems from microphone to cloud AI will be introduced and explored with some examples, along with some usual (and unusual) obstacles and challenges. Practical examples on how to integrate voice control into IoT-Devices will be given, and topics like usability, privacy and interoperability will also be addressed. All for One: The Pillars of a Voice Assistant A voice assistant is comprised of four main modules: Automatic Speech Recognition (ASR), Natural Language Understanding (NLU), Natural Language Generation (NLG) and Text To Speech (TTS). The presentation will offer an overview of the core technologies used for each module and portray the principles of language technologies. The technological and user experience differences between Bixby and other voice assistants will also be analyzed, with a special focus on 3rd party integration. A UX Guideline to Humans With the rise of voice assistants, humans no longer have to adapt to technology – the burden is now on voice assistants such as Samsung's Bixby. Humans no longer try to understand devices, devices instead have to try to understand humans. We will highlight the past, present and future of voice interfaces and what it means for UX-Design.

    What we can learn from epic fails to build a better IoT. A talk by Mirko Ross (@mirko_ross on Twitter) The talk can be held in English if necessary. Please register at: [masked] German abstract: +++ Wenn der Teddybär zur Abhör-Wanze wird...+++ Dieser Witz ist bereits ein Klassiker: "Das S in der Abkürzung IoT steht für Sicherheit". Das Internet der Dinge oder englisch abgekürzt IoT, ist eine relative junge Disziplin, die sich leider schon einen zweifelhaften Ruf in Punkto Sicherheit erworben hat. Dass dem so ist, liegt im wahrsten Sinne in der Natur der "Dinge". Das Internet der Dinge verfügt über einen hohen Grad an Komplexität, mit vielen Fallstricken für erfahrene und unerfahrene Entwickler. Zudem erfordert die Fertigungstiefe der Produkte ein Zusammenspiel von vielen Fachexperten, Zulieferern und Dienstleistern. Fehler zu Lasten der Sicherheit und des Datenschutzes sind in dieser komplexen Disziplin geradezu vorprogrammiert. Doch Entwickler und Unternehmen können aus spektakulären Fehlern der Vergangenheit lernen, um zukünftig bessere und sicherere Produkte zu bauen. Es lohnst sich also, einen Blick auf spektakuläre Fehler zu werfen. Dieser Vortrag nimmt die Zuhörer auf eine spannende und lehrreiche Reise durch die schlimmsten IoT-Produkte und deren Sicherheitslücken. Das Ziel: aus Fehlern lernen und bessere IoT-Produkte gestalten. ________________ Mirko Ross ist Gründungsgesellschafter und CEO der digital worx GmbH, einem Software-Unternehmen für mobile Anwendungen mit Sitz in Stuttgart-Vaihingen. 1998 gründete er sein erstes Unternehmen im Technologiebereich.
