I finally decided to start writing a tech blog where I can share several technical topics that I am adopting, studying and exploring. Why did I decided to publish one? There are two main reasons: 1) I usually take notes and write a summary via my private OneNote every time I delve deeper into a topic. Instead to keep those private, I thought it would be beneficial if I share those summaries with other people. In this way I can give something back to the world of internet as the majority of my summaries’sources are free ones and available on the web. 2)We get a better understanding of a topic when we have to explain it to other people.
