How to structure your program right? This has been a central question since the beginning of software development. This talk takes a look into the history of software architecture to understand why we are building software the way we are. We start with foundations like information hiding, modularity, separation of concerns, loose coupling. We move on to principles like layering and design patterns. We conclude with an outlook to modern ideas like hexagonal architecture, onion architecture,…

Die Entwicklung typischer aktueller Webanwendungen kann einen erschlagen: Umfangreiche, komplexe JavaScript-Frameworks, Client-Side-Rendering/Server-Side-Rendering, (De-)Hydration, komplizierte Buildprozesse und und und

Die unterliegenden Technologien, Protokolle und Architekturmuster wie HTTP(2/3), HTML/CSS, Web Components, Representational State Transfer (REST) u. a. geraten dabei manchmal völlig aus dem Blick. Für die Entwicklung von Webanwendungen, die nachhaltig und skalierbar sein sollen,…

What is the difference of a test architect to a commonly known software architect? And why do I need one? What do they have in common and where do they differ? Is there a gap where we need a bridge (Spoiler: yes)? What are the different expectations of other roles on a test architect?

Questions over questions which will be covered in this talk. With examples where it did go well because there was a test architect and examples where things got haywire maybe because a test architect was missing.

The objective of visual test automation is replace flaky and hard to read selectors with images. Many software packages offer the possibility of using images as selectors, but it rarely works reliably. Appium has the function "findElementByImage," Playwright has functions like "toHaveScreenshot." Code and no-code tools alike provide a number of options to tweak the sensitivity, where both, too low and to high values, produce their own set of artefacts. What makes this so difficult? Doesn't AI…

Retrospectives are the key event for ensuring continuous improvement in agile and non-agile teams. However, many participants tend to have bad experiences with poorly facilitated retrospectives, which demotivates them from sharing personal insights and, in the end, might lead to a cancelling of retrospectives from the team's schedule.

There are many books and articles about how a good retrospective looks like. They describe the result but often they lack the crucial part of HOW to get to…

Consider for example, this line of C++ code:

std::pmr::vector<std::variant<int,double,std::pmr::string>> values;

Are you aware that this line of code contains at least five Gang-of-Four (GoF) design patterns? If not, then this talk is definitely for you! It will help you realize that design patterns are everywhere. They are the key to managing dependencies between software entities. They help us to structure our software, to separate concerns, and to communicate our intentions. Even better, they…

So... in our organisation we've been busy trying to bridge the gap between Dev and Ops. And we've been moving towards an almost completely automated Infrastructure enablement. We thought we were doing so well. And then... it turned out that even without human intervention, IT infrastructure is secretly still about human interaction. I will tell you our real life story of how we hit rock bottom Developer Experience because as enablement teams we were so focused on IaC and automating everything…

In this constantly changing world, we face new challenges: rapidly changing customer needs, increasing competition, and a shortage of skilled workers. Agility and speed are essential. Adopting Platform Engineering can be key, providing the flexibility and scalability to adapt swiftly, outpace competitors, and bridge the skills gap through automation and optimization.

I will demonstrate, using a real Platform, how Platform Engineering can help companies overcome hurdles and scale issues with…

In an era where digital transformation is paramount, regulatory frameworks like the European Data Act and the upcoming Financial Data Access (FIDA) are reshaping the landscape of data management and security. Our presentation aims to demystify the complexities of API security and user consent management under these new regulations, drawing parallels from the successful GSMA Open Gateway Initiative in the telecommunications sector.

Key Points of Discussion:

Introduction to API Challenges in…

Measuring software engineering productivity can significantly enhance managerial decision-making, improve developer enablement, and optimize development workflows. However, despite the potential benefits, there is no uniform approach in industry or research. We present our solution, which is designed to use quantitative data generated during the development process. We gather data from popular software development tools, looking further then simply using the oversimplified source lines of code…

If you ship a software product that includes open-source software, (1) you need to make sure it does not include unwanted open source code, (2) you need to declare its software bill of materials, (3) you need to create and deliver correct legal notices, and (4) you need to monitor security vulnerabilities of your current and past shipped code. Ignore these requirements, and you risk being sued by copyright trolls or get embarrassed by irate customers. This tutorial shows you how to get…

In der dynamischen Welt der Softwareentwicklung ist eine effiziente interne Entwicklungsplattform der Schlüssel zum Erfolg, denn sie steigert die Effizienz der Entwickler durch einen schnelleren Weg zum Produktionsbetrieb und standardisiert Sicherheit und Compliance für alle Anwendungen innerhalb eines Unternehmens.

Dieser Vortrag stellt das CNCF Reifemodell für Platform Engineering vor um interne Entwicklungsplattformen an den Anforderungen des Businesses und der Organisation zu optimieren. Das…

In den letzten 2 Jahren haben cloud-basierte Entwicklungsumgebungen wie Gitpod oder GitHub Codespaces stark an Popularität gewonnen. Mit Devpod kam vor kurzem eine neue Open Source Technologie in diesem Feld dazu und es ist sehr wahrscheinlich, daß es in naher Zukunft noch weitere Neuerscheinungen geben wird.

Mit diesem Vortrag vergleiche ich den Ansatz dieser Technologien im Vergleich zu traditionellen IDEs und versuche die Rolle der Container Technologie - insbesonders der devcontainer…

The Japanese philosophy of Wabi-Sabi celebrates the beauty of imperfection. I will explore how applying such principles to software engineering projects can enhance the outcomes. Using the relaunch of my client's content-driven website as a case study, I will demonstrate how an open and positive attitude, combined with flexibility and a readiness to embrace unconventional methods, has led to better results. The aim of this talk is to enable project team members to confidently navigate the…

Software development is a profession, discipline and industry obsessed with solutions. It places justifiably high value on answers... but what if we take a step back for a moment to consider that an answer arises as a response to a question? And, therefore, perhaps we should be placing more focus on asking questions.

The right questions can be more powerful in the long run than answers. Answers may shift as specific technologies change beneath our feet, but if we are able to frame the right…

As a tech lead or senior developer, you’re expected to mentor and train more junior team members - coaching is already part of your job. In this masterclass with Emily Bache, you’ll learn skills and concrete activities you can use to bring on others and build up your team. You don’t need to be a full-time technical coach to make a difference in your organization, and this training will help you to get started with learning hours. These are not vacuous “icebreaker”-style fun and games, the focus…

Good Software Design — the proper management of dependencies — is the foundation for the success of a project. The basic building blocks for software design are design patterns. Design patterns have proven themselves invaluable over several decades and thus knowledge about them is essential to design robust, decoupled systems. Modern C++, however, has profoundly changed the way we use C++, how we think about design and implement solutions. This also affects how we implement design patterns.

This…
