In this fast changing world and the adoption of Agile processes, the customer exposure of the developers is increasing. This introduces a demand for new set of skills. Developers are expected to communicate and collaborate with the customer closely. This creates a new set of challenges every developer will face. Soft skills are now becoming a common asset for every developer.

Internet of Things is becoming the heart of more and more projects. Each IoT project starts with a PoC prototype. This workshop will walk you through what a prototyping platform is and how it impacts the development of a project. Using the Bosch XDK, we will go through what such a board offers as sensors, connectivity, functionality and extensions and interesting examples from the real world. Bosch and Zuhlke developed the platform to encourage community development and open source coding thus we will see some live coding on the stop.

Our fantastic apps deserve the right infrastructure! In this talk we will make a short introduction to Kubernetes (K8s). Next we will dockerize and deploy two simple applications into a k8s cluster.

Our ambitious goal is that the audience will feel comfy with what we are doing and will be able to easily follow us. No prior knowledge of k8s is required! The apps and the scripts that we are going to use will be available at Github.

The talk will begin with a quick glimpse into the k8s architecture. Then we will go a bit deeper with some of the most important k8s objects like Nodes, Controllers, Services. When we lay down the foundations it will be time to introduce our sample applications – a small Spring Boot backend and an Angular frontend which offers the possibility for amusing interaction with the attendees (e.g. by scanning a QR Code). At the end we will deploy these apps in GClould and/or Minikube and see them up and running.

One of the most important properties of modern frontend applications is reliability. Want to learn how to build frontend applications that never crash? Join me and let’s dive into the know-how of making your apps more reliable and your development process more focused with the help of our fp-ts library and its large ecosystem. I’ll share insights on true type safety with Typescript, runtime exception safety, IO safety, and much more.

Kubernetes does all the boring yet critical tasks like horizontal scaling and zero down-time deployments, but what about more complex tasks like database sharding and agent registration?
Kubernetes operators are capable of automating complex tasks, reducing the human factor even more. The barrier to entry is not as high as you think!

To a certain extent you can reuse the code when building mobile applications both for iOS and Android. Ideally, you want to reuse as much as possible to save time. In client-server apps, shared logic can be moved to the server-side, and most of the time, it’s acceptable. But what if it’s not in favor of the UX? What if it’s the kind that can’t be moved? What if you don’t even have a server? Can you optimize, or is it time to double the work and time spent fixing bugs to account for different platforms?

This is where J2ObjC comes into play. J2ObjC is an open-source tool from Google that can translate source code written in Java into Objective-C. This way, Java source can become a part of the iOS builds.

Devexperts have been tailoring code translation from Java to ObjC for years, and this approach is integrated deeply into our development process. We’re here to inspire you to give it a try yourself by showcasing some of our biggest wins with J2ObjC. The road ahead is scary. Fear not, we’ve got the painkiller for easily integrating J2ObjC into the development pipeline.

Insatiable market hunger for the new features and the ever-increasing development speed, as well as the complexity of the applications being created, require the team to make the product testable by design.

How to manage application quality with limited resources?
How to make auto tests decrease business risks?
How to create optimal auto test coverage and naturally maintain it throughout the entire application development cycle?
How to create the most understandable and maintainable user documentation?
How to build auto tested release process?
How much does full test coverage cost?

Get the answers to these and other important questions in this presentation.

Since the release of C++11 in 2011, modern C++ code does not look at all like C++ code written before 2011. If you know the old C++ language, then you will have to unlearn certain things to write truly modern C++ code. Recent versions of the C++ standard have introduced new features to make your live as a developer easier. These features allow you to write code that is less error-prone, that is more easy to read and understand, that allow you to more easily use other aspects of the languages such as the Standard Library algorithms, that make it easier to write multithreaded code, and so on. This session will give an overview of these modern C++ features.

The talk will bring attendees on a journey from the current out of the box approach to UI automation testing, talk about the pitfalls and then introduce through Swift, the Robot pattern. The Robot pattern is a pattern commonly applied to test automation which allows an abstraction layer that is easy to write and easy to understand, so much so that even a product manager could write the tests. Moving beyond the basics of the pattern and show it running in action with a real app, we will evolve the pattern to leverage the latest function builders offered in Swift 5 to make our tests even more expressive, terse and easy to write.

Attendees will leave, having a new found love for test automation and how to put a strong pattern to use in their own code bases.

All systems have some degree of legacy, starting from the new one that you are creating just now, up to the one that has been abandoned for years but still keeps one critical active user somewhere. At some point in your career as a developer, you will inevitably end up maintaining a system that you didn’t write, and which you don’t know much about. What are your options? Are there tools and techniques that can make you work easier? Yes, there are! In this talk I’ll go over different approaches that will improve your experience dealing with a legacy system, and also, a set of recommendations for preventing future systems becoming legacy.

Data masking has many uses – from preparing good test data based on real data to sharing data for analysis. In the presentation I’ll share my study as examples on CSV files
