It all started when a student wanted to write his own terminal emulation program. Then he began to develop and supplement it and suddenly noticed that he had an operating system. Linus called it Linux and posted it on the Internet, encouraging those who wanted to make changes to the system. And programmers from all countries, united, began to work on it. “Just for fun” is a mixture of autobiography with discussions about technologies and ways of their development. For readers new to programming, Torvalds tells a fascinating story of his life. This is the story of a young man who, despite the rapid rise of his career, did not feel dizzy. Linus even makes a half-joking attempt to discover the meaning of life. For techies, this is a report on one of the most interesting computer projects. The initiator of this project explains in detail how Linux has evolved from a toy of a dozen hackers into a powerful tool used by huge corporations. Along the way, he shares with readers his ideas about the future of Linux and the computer industry as a whole.
