Time to have Dinnr


I’m in my last of 12 weeks Makers Academy. It’s hard to believe and at the same time I’m okay with it. Maybe I’m spoiled by our smooth and rewarding final project but I feel ready for the market. I want to build apps that are actually used. But before I tell you about my plans (in another post) I will tell you about „Dinnr„. The idea was pitched to us by my friend Patrick Abele. […]

RSpec test: force the function return a specific value I implemented an if-statement in my landing- and take-off-procedures. So […]

For someone like me, new to development, it sounds really strange to write a test before having a function or product ready. But anybody at Makers Academy is a 100% convinced that the so called technique of “Test Driven Development” (TDD) is absolutely essential for writing good, maintainable code. What it is and how it works (non-technically spoken) In TDD developers at first break their problem down into objects and actions. In our first week’s […]
