B. Sc. Applied Computer Science
Full Stack Web Developer
Yannic Schröer
I studied applied computer science because I love designing and building things. High-quality and usability are my main focus, which is why I am also on fire for concepts like Test-driven Development and Clean Code, even though I might not be an expert yet.

Hyrum's Law of Implicit Dependencies
If Hyrum’s Law would be a movie I would describe it as: The consequences of bad documentation and assumptions on interfaces.
SOLID Principles with Python Code Examples
SOLID Principles – If you are a professional developer, there’s no way around these rules for object-oriented software design.
No matching distribution found for pkg-resources==0.0.0
Wonder what the f**k pkg-resources==0.0.0 is? This is caused by an error of the virtualenv library. Learn how to fix it.
Bubble Sort, Big O and visualization with Python
In this post about the bubble sort algorithm in Python, we want to look into how to implement and visualize it. Bubble sort isn’t quite an efficient algorithm when it comes to time complexity. However, it is easy to code and to understand, so it is often an introductory problem for computer science students and pupils.
GRASP - General Responsibility Assignment Software Principles
GRASP is an acronym for General Responsibility Assignment Software Principles. In this article, we want to point out these principles and how they work.
Visualize K Means Algorithm in Python
In this article we want to take a look at the k-means algorithm. The k-means algorithm is used to determine clusters. It is often the first algorithm you will see in any machine learning introduction, as it is easy to understand. We will code the algorithm in Python and also visualize it.
Midpoint Line Algorithm
The midpoint line algorithm is a drawing algorithm in the field of computer graphics. It is used to determine how lines are translated into pixels.
Underscores in Python
Python is a great language in my eyes, it’s simple to understand, write and its indentation forces at least a bit of styling into the code. But when it comes to underscores, there’s often confusion.
Concurrency in Python
Concurrency is a powerful concept to execute various commands parallely. It is available in nearly any programming language but is often difficult to understand or implement. I will focus on explaining this in the context of a current Windows OS and the concurrency how-tos will use Python as a language.
Do one thing - Not the single responsibility principle (SRP)
The “Do one thing” rule for programming is essential to everyone’s clean code philosophy. Learn why and how to apply it.
KISS Principle (Keep it simple stupid)
KISS - an acronym for “keep it simple stupid” is a design rule that every professional developer should apply to their code. It reduces complexity and improves readability as well as maintainability by aiming for the simplest solution.
DRY Principle
Do you tend to repeat code over and over again? There are several important reasons besides DRY (Don’t Repeat Yourself) not to do so.
