Hero attack: four top hackers

This article selects four top legal hackers and their technological innovations. The following is their story:
Woz is often called the second employee of Apple founder Steve Jobs. he and Steve Jobs created an Apple Computer. woz started his hackers' career by making blue boxes. This is a bypass technology that allows users to make long-distance calls for free. woz and Steve Jobs sold the blue boxes to their classmates. They even used the Blue Box phone to pretend to be Kissinger and call the Pope.
Woz lost school and invented his computer.

 

Stephen Wozniak Jobs suggested selling such computers as self-assembled computer circuit boards, which were the original type of Apple's computer. They sell Apple computers to a local distributor at a unit price of $666.66 per unit. Woz is now dedicated to philanthropy and is no longer working full-time at Apple. He now seems to have "adopted" The rosgaatu-salataga Union High School campus with many Asian students. He personally taught students and teachers and donated some first-class equipment.

Tim Berners-Lee He is considered to be the founder of the World Wide Web. He has been hailed as one of the countless Millennium renewal awards. When he was still at Oxford University, he and his classmates were found to have stolen passwords from computers, so he was banned from using school computers. Tim Berners-Lee believes that hypertext should be associated with the computer network. When he recalled how he combined the two, he said: I only associate hypertext with TCP and DNS, and the World Wide Web is born.

After the emergence of the World Wide Web, he created the World Wide Web Association at the Massachusetts Institute of Technology. Members of the Association called themselves a group of Members who gather together to develop webpage rules. Berners-Lee's World Wide Web and all the rules set by the World Wide Web association do not apply for patents or require any royalties.

Torvalds Torvalds creates a UNIX-based Linux operating system. He made himself a programmer. It said its ideal was simple: I just wanted to have fun with the best operating systems in the manufacturing world. Torvalds's hackers' career began in their teens, in a family of 8-bit machine, using assembly language to write a Commodore Vic-20 microprogram, the reason for the use of assembly language, the main reason is that he didn't know that other programming tools were available at that time.

In the summer of, six months after January 1, had the first PC, he felt that he was supposed to download some files.

But before he can read and write to the disk, he had to write a disk driver. You also need to write a file system. In this way, the task Conversion Function and the file system and Device Driver become UNIX, at least the Unix kernel. Linux was born. Later, he applied for an FTP server space from the University of Helsinki to allow others to download the public version of Linux, use GPL for Linux, and continuously improve it through hacker patches, it works well with existing GNU applications. In this way, Linux has a graphical user interface overnight, and does not continue to expand. To praise him for his outstanding contribution, an minor named after him and received a honorary doctorate from the University of Stockholm in Sweden and the University of Helsinki in Finland, it is also called "the hero of 1960s ".

Richard Stallman Stallman, named after the GNU project, is dedicated to developing a free operating system. To this end, he became the spiritual leader of free software. His famous "serious Biography" said: Paid software makes users helpless and independent, and cannot be shared or changed. A free operating system is vital for people to use their computers freely. Stallman started his hacking career at MIT. He became a professional hacker in EMAC and other projects. He severely criticized computer intervention in the lab. Every time the password of a lab computer is installed, he needs to break it down and change it to the initialization state, and then sends an email to the user of the computer to notify them that the password has been removed.

Stallman's Free Software journey started with the printer.

The first printer bought by the mit ai lab comes with the source code of the driver. Hackers at the mit ai lab can fix the bug of the printer driver on their own, or modify the driver of the printer as needed, which brings great convenience to their work. Later, MIT bought another laser printer. This time, the manufacturer only provided a binary printer driver, which is the only software provided by MIT without source code. For work, Richard Stallman wants to modify the driver, but he cannot because he does not have the driver source code. This causes a lot of inconvenience to your work. It also makes Stallman more aware of the value of free software. Stallman is still committed to developing free software. He opposed the protection of digital copyrights. He believed that the behavior of the source code is in line with professional ethics. He received many honors, including many awards and honorary doctorate degrees. Currently, he is an academician of the National Emy of sciences.
