Reduce Waste with Clever Communication

A lot of time and energy is wasted every day due to inefficient communication in development projects, maintenance teams and IT operations units.

Top 11 Tips to Develop Unmaintainable Code

Have an excellent paid job for the rest of your life. The key skill is the obfuscation of the code, besides poor design, no test cases and overly complex algorithms.

The technical and business know-how is more important for younger software engineers and the soft skills getting increasingly relevant for senior software engineers.

The following article describes the most important misconceptions concerning IT security. Includes some helpful tips and links.

Simple Damped Pendulum - Solved and Visualised with R

This article describes how to solve the differential equations of a damped pendulum with the R language and render resulting diagrams in a web page.

Emotional Intelligence is a key success factor in business and private life. As Software Engineers emotions are usually not your main focus in daily work. Our strengths are logic, algorithms, rational behavior and solving difficult puzzles.

This experiment shows an Artificial Neural Network which learns to detect the frequency of the input signal independent from the phase. You may start here with desktop browser.
