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.

Under his theory, users copying software from each other is not only not "piracy", but reflects the mutual virtue of human nature.

For Stallman, freedom is fundamental. Users can freely share software results and copy and modify the code at will.

He said: "Think about it, if someone says to you: 'As long as you promise not to copy it for other people to use, I will copy these treasures to you.' In fact, such people are devils; and those who are tempted to be devils

, is someone who sells high-priced software. "It can be concluded that the biggest change that has occurred in the software industry at the end of the century is the overall revival of free software.

Under the wave of free software, the business model of the software industry will be completely transformed, from selling program code as the center to service as the center.

As a computer user today, if your friend wants you to make a copy of a copyrighted program for him, you should not refuse. The spirit of cooperation is more important than copyright.

Moreover, this kind of cooperation should not only happen underground, everyone should be proud of it, open up his honest life, and say "no" to all proprietary software.

You should be able to collaborate openly and freely with other software users. You should have the right to understand how the software works and teach it to your students. When something goes wrong with the software, you can hire your favorite programmer to fix it.

Revise.

You deserve free software.

"Some people say that Stallman should be regarded as the greatest programmer in the world and has written the most software. However, Stallman's real power is his thought. Therefore, his most admired hero is South Africa's Mann

Draup. John Draup Circle Title: Cap'n Crunch (Captain Crunch) Major Achievements: Discovered how to use the prize whistle in the ("Cap'n Crunch") cereal box (blow into the phone receiver)

Free (long-distance) calls. Cap'n Crunch introduced generations of hackers to the brilliant idea of ??"stealing phone lines" to make (long-distance) calls: his first experience with computers: as a teenager, trying to convince himself of a coin-operated pay phone.

coins and connects his phone. His own unique tool: a toy whistle inside a Captain Crunch cereal box that produces a 2600 Hz tone, which turns on a blue box for outgoing calls.

Using this device to hack into the telephone system), users can also make free (long-distance) calls (the subsequent Oscar Meyer Weiner whistle was also favored by phone phreaks for a time) Born in rural America in 1943.

Draup has shown a strong rebellious character since he was a child. This character determines his unique hacker appearance in the future. However, despite his lonely personality, he has an extremely developed brain.

, which often allows him to acquire new knowledge faster than others. In the early 1960s, Drapor began to come into contact with the new thing of computers. Although the computer at that time was just a huge, complicated, and dull thing,

This was enough to make Delapor enchanted.
