Linus Torvalds is the most famous computer programmer and hacker in the world today.

Inventor of the Linux kernel and collaborator on the project.

Torvalds used his personal time and equipment to create one of the most popular operating system kernels in the world today.

Free software has evolved from an industrial ideological movement into a market commercial movement, and has since changed the face of the software industry and even the IT industry.

Chad Stallman Personal profile: Title in the circle: None (no hiding it!) Main achievements: Veteran hacker.

In 1971, Stallman found a job on the street at MIT's Artificial Intelligence Laboratory.

He was an undergraduate at Harvard University at the time.

Later, Stallman founded the Free Software Foundation, breaking the concept of software as private property.

First contact with computers: at the IBM New York Science Center in 1969, when he was 16 years old.

His own unique hacking tools: In the 1980s, Stallman was not receiving a salary from MIT but continued to work in one of its offices.

There he created a new operating system, GNU - short for "GNU's Not Unix".

Little-known fact: Received a $240,000 Genius Grant from the MacArthur Foundation.

He has a short figure, slovenly appearance, shoulder-length hair, sideburns, and a fashionable half-sleeved beach top, looking like a Beatle.

Looks like a savage in a modern city.

If he puts on a "linen monk's robe" and a round wide-brimmed hat, it will be like the halo surrounding the head of the icon in the painting.

In the blink of an eye, he transformed into the appearance of Jesus Christ in the Bible, exuding the majesty and power of a prophet.

Savage and Christ are precisely the dual attributes of Richard Stallman, the spiritual leader of free software: he is both a barbaric subversive in today's proprietary (private) commercial software field, and a sacred figure in the hearts of countless programmers and users.

God of freedom.
