I am a person who alwyas want to learn something new and interesting. With decades on my shoulder in developing/consulting systems I am at last in a very happy situation: I can develop applications merely just for fun. I have tried and used a lot of different developing environments/programm languages (the very old ones perhaps can remember on such dinosaurs like Algol/Fortan/Cobol/PL1, the simple old ones on Basic/dBase/Clipper/FoxPro, the not so old ones on VisualBasic/HTML/CSS/PHP). Recently I have mainly worked in C#, Java and my favourite: kotlin.
