This is usually the title of anyone’s first blogpost (especially if you use WordPress). Furthermore, having the computer say “Hello, World!” is normally the first piece of code that we practice while learning a new programming language.
But why? What motivates us to have our computer say “Hello, World!”?
My initial theory
I had several theories for this tradition.
One of them was us humans feeling like gods, creating something to make it talk not only to ourselves, but to the entire world. Here we were, feeling proud of our creation and wanting to share it with the entire human race.
Another theory I had was that this was made popular by Apple in the introduction of the infamous Macintosh in 1984. Probably motivated by the picture bellow of the Mac saying “hello.”
But considering that this is my first blogpost on wdavis.me and that I’ve always been curious about why we start our online creative journey with these two words, I decided to do a bit of research.
According to many online sources, including this article on Wikipedia, this tradition accidentally started when Brian Kernighan wrote a program on an internal memo while working in Bell Laboratories ca. 1972. This program, which was part of a tutorial about programming in C, prints “hello, world” on the terminal without the capital letters and exclamation mark that we currently use, and was one of the first examples that any newbie played around with.
Ever since, anyone who started learning how to code continued the tradition, perhaps unknowingly. The fact that other books adopted this example resulted in even more computers saluting the planet. Considering that there are 500 new WordPress sites created every day, I think it’s safe to say that this tradition will not end for the foreseeable future.
What to expect from this blog
I’m an avid reader and always curious to learn more and more about anything that I’m passionate about: Internet, Product Management, leadership, fitness, business, finance… Up until now, I’ve been storing all the knowledge I gathered and consumed in my head, but I decided to put it in writing so that I can share it and I can organise it better.
What else to say? Thank you for reading, looking forward to this journey, and, of course: “Hello, World!”.
