C# and FP – episode 2 – OOP today, (im)mutability.

Introduction

An object’s state, describes its current condition. If object was a human, this could be their emotional state (e.g happy, sad, angry). To think a bit further, the height value in an object’s field is not a state, but the height’s value help us to define it’s height category (e.g tall, short, average), that is actually the state. And it is the state, based on the context we, as society, have set on defining when someone is considered tall or not.

Women as software developers

Introduction

Although I am trying to avoid commenting politics, I believe it’s better to talk rather than keep my mouth shut. Shutting my mouth is the easy task. The motive I am writing this piece, is Greta Thunberg, and the comments full of hate and sexism (unfortunately), I have been reading against her during her visit in the USA, and her presence at the 2019 UN climate action summit in New York. I will not comment on Greta’s actions on environmental awareness, or the hateful comments about her. The whole thing is just a strong motivation for me to express my thoughts on the “women as software developers” issue, that has been quite strong in the past few years.
