Open source is more than free software: licenses, maintenance, quality, and the question of what you can give back to the community.

Architecture Documentation That Really Makes a Difference
Software architecture doesn’t become obsolete only after years—sometimes it happens even as you’re writing it. Which decisions really need to be set in stone, and which ones can safely remain open.
Why German corporations are becoming unable to act
German companies want AI and robotics, but their processes are blocking any progress. Why no business case makes sense as long as data silos remain.
Why COBOL Developers Prefer Writing Tests in Java
COBOL developers said writing unit tests in Java was easier than in their own language. Here's the interface architecture that made that possible on a 60-year-old mainframe.
Testing thermal management in e-cars
200 possible system states, a virtual control unit instead of a physical test cabinet: how thermal management tests in electric cars are becoming earlier and more precise.
Contract testing - Who really needs it?
Let API interfaces continue to break silently or recognize them early? Contract testing shows how consumers specify what they need and changes stop the pipeline.
Wind and weather - the challenges of testing wind turbines
164 subsystems, lightning protection according to national law, offshore turbines without service access: testing software in wind turbines is more complex than it seems.
Code quality, metrics and mindset for students
Teaching testing in university before real projects put pressure on you: Why architecture trumps testability and ChatGPT disguises it.
Creating a good working atmosphere
Developer friendliness costs time in the short term, but saves it in the long term - and makes teams measurably happier. REST mocks and test interfaces from a real project show what this means in concrete terms.
Synthetic test data
Anyone who builds test data manually or derives it from production data risks GDPR problems and hardly finds any new bugs. How synthetic generation solves this.
Testing enterprise software correctly
Anyone who configures SAP always tests side effects. Why enterprise testing needs different rules and how experts without a testing background can still get fit.
Testing microservices
From a sluggish monolith with hours of end-to-end testing to fast microservices: Which test strategy really works for this.
Testing web components vs. UI elements
280 UI tests, under three minutes, no backend required: How isolated UI testing with mocked API responses becomes faster and more stable than classic component or E2E testing.
CI Pipelines
Those who test don't protect themselves, they protect everyone. How a test network works in embedded development and why CMake, Google Test and a self-built automocker are the key.
Why is code so hard to understand?
Why does your brain just not understand some code? Working memory only processes four chunks at a time, and good code respects this limit.
Software Analysis
What happens when a third of the adopted code is only available as a black box? How an agile mindset and honesty can save a ticket store project.
Shift Left but Right
Why do testing activities always end in a traffic jam just before go-live? Shift left alone is not enough: How synthetic monitoring reuses the same test case.
Test data and data processes
Production data often only covers 70% of test cases. How to systematically test data processes and get business and IT on the same page.
Testing embedded systems
Testing embedded software without having the hardware? How unit tests, CI pipelines and MISRA standards interact in practice.
Efficient form tests
255 form variants, 16 federal states, sometimes over 100 fields per form: How model-based test data generation and generic UI automation make this effort manageable.
Best practices for (architecture) documentation
Architecture documentation quickly becomes outdated because the tools slow it down. Documentation as Code and Continuous Documentation solve exactly that.
Quality from an architectural perspective
Separating functional and quality requirements: useful or misleading? What this distinction really means for architecture decisions.
Test data management
Five different tools, manual errors when transferring, no cross-system solution: this is what test data management looked like in practice before a store concept changed everything.
Designing architecture together
Teams often make architecture decisions unconsciously while coding. Three experiments show how this can be achieved jointly and comprehensibly.
How do I survive a cloud migration?
Cloud migration sounds like technology, but it is largely a question of organization. Why monoliths, DBAs and silos often slow things down more than the infrastructure.
Sociable testing
Why are hundreds of unit testers created, but the software still doesn't run? Because isolated tests alone do not prove a feature - and that is the problem.
C++ Quality by Design
C++ is 45 years old and yet deeply rooted in autonomous driving, medical devices and AI libraries. What the Core Guidelines have to do with it.
Contract-Based Testing
Contract-based testing decouples providers and consumers so that interface changes no longer deliver any nasty surprises. How this works in practice.
