💡FUN FACT 💡Linus Torvalds (creator of Linux) originally wanted to call his invention "Freax", a portmanteau of "free", "freak", and "x" (as an allusion to Unix). However, Ari Lemmke, Torvalds' coworker at the Helsinki University of Technology (HUT), did not think that "Freax" was a good name. So, he named the project "Linux" on the server without consulting Torvalds. Later, however, Torvalds consented to "Linux".
