Hi! My name is Rafał (pronounced as [ˈrafaw]). I started my professional adventure in 2013. Since 2019, I have been the owner of AVISPA SOFTWARE. You can read more about me in Who am I? tab.

The initial greeting, although not very original, is not accidental. According to Jargon File – a comprehensive compendium of hacker slang – “Hello, World!” phrase first appeared in a program written in BCPL language (an acronym Basic Combined Programming Language) created in 1976.

The real fame of “Hello, World!” however, it gained value after the publication of the book “The C Programming Language” by Brian Kernighan and Dennis Ritchie in 1978, where it was included in the following sample program:

main( ) {
    printf("hello, world\n");
}

Currently, the term “Hello, World!” refers to a simple program, often designed to display precisely that phrase. It is used to showcase the syntax of a programming language. It is also written as the first program by individuals looking to learn that language.

“Hello, World!” it is therefore a kind of beginning, an invitation to further exploration of a given issue. In this way, I invite you to explore my website 🙂
