Linus Torvalds

Linus Torvalds makes computer programs.

He made a tool called Linux. Linux helps many computers work. He also made a tool called Git.

He was born in Finland. He moved to the United States later. He has three daughters. He also likes to dive in the sea. He is a very important computer worker.

Linus Torvalds is a famous software engineer.

He was born in Finland in 1969. He grew up loving computers. When he was 11, he started writing code. He even made his own games.

In 1991, he began a big project. He created the Linux kernel. A kernel is the main part of an operating system. It helps the computer's parts talk to each other. He shared his work on the internet. Soon, many people helped him. Today, Linux is used by many computers. He also made a tool called Git. Git helps people track changes in their work.

Linus has won many big prizes. One was the Millennium Technology Prize in 2012. He also won the IEEE Masaru Ibuka Award in 2018.

He now lives in Oregon in the United States. He likes to go scuba diving in the sea. He even made a program to help plan dives. He is a very important person in the world of computers.

Linus Torvalds is a famous software engineer who changed how computers work.

He was born in Helsinki, Finland, on December 28, 1969. His parents were both journalists. He grew up in a family that spoke Swedish. Linus loved computers from a very young age. At age 11, he started using a VIC-20 computer. He learned to write code using a language called BASIC. He even made his own games, like a Pac-Man clone called Cool Man.

In 1991, Linus began a project that would change the world. He created the Linux kernel. A kernel is the most important part of an operating system. It acts like a bridge between the computer hardware and the software. Linus first shared his work on an FTP server at his university. He wanted to make a system that was free for everyone to use. Because of this, he used the GNU General Public License. This license allows people to see and change the code. Many people from all over the world began helping him. This way of working is called open source.

Linus studied at the University of Helsinki for many years. He earned a master's degree in computer science there. During his studies, he also served in the Finnish Navy. He was an artillery observer and reached the rank of second lieutenant. In 1991, he bought an IBM PC clone to work on his code. This computer helped him build the first versions of Linux. He released version 1.0 of the kernel in March 1994. Later, he moved to California to work for a company called Transmeta. Eventually, he moved to Oregon to be near the Linux Foundation.

Linus has received many important awards for his hard work. In 2012, he won the Millennium Technology Prize. This prize recognized his work on the Linux kernel. He also won the IEEE Computer Society Computer Pioneer Award in 2014. In 2018, he received the IEEE Masaru Ibuka Consumer Electronics Award.

In 1999, a magazine named him one of the top 100 innovators. His work became very valuable to big companies like Red Hat. He also created a tool called Git in 2005. Git is a system that helps many people track changes in their code.

Today, Linus still helps manage the Linux kernel. He decides which new pieces of code get added to the system. He also uses his skills for other hobbies. He loves scuba diving in the ocean. He even wrote a program called Subsurface to help plan his dives. Linus is married to Tove Torvalds, who is a karate champion. They have three daughters together. He believes that making things for everyone to use is the right way to do software. His work helps keep the digital world running every single day.

Linus Benedict Torvalds is a Finnish and American software engineer. He is most famous as the creator and lead developer of the Linux kernel. A kernel is the core part of an operating system. It manages the communication between a computer's hardware and its software. Since 1991, Torvalds has guided the development of this essential technology. His work has shaped how modern computers, servers, and many devices function.

Torvalds began his journey with computers at age 11 in 1981. He started by programming a VIC-20 computer using a language called BASIC. He later learned to use machine code to talk directly to the computer's CPU. He also modified a Sinclair QL computer and wrote his own tools for it. This early experience helped him understand how computers work at a very deep level. He eventually earned a master's degree in computer science from the University of Helsinki. During his studies, he also served as a second lieutenant in the Finnish Navy.

In 1991, Torvalds began working on the Linux kernel. He used an Intel 80386-based IBM PC clone to build his first prototypes. He initially wanted to name the system "Freax." However, his friend Ari Lemmke named the directory "linux" on the university's FTP server. This was the first time the code was shared on the Internet. Torvalds eventually adopted the GNU General Public License version 2. This license is a type of open source agreement. It allows anyone to see, change, and share the software. This open approach allowed thousands of developers to contribute to the project.

Managing such a massive project requires special tools. In 2005, Torvalds created Git, a distributed version control system. Version control is a way for many people to work on the same code without breaking it. Git helps developers track every change made to a project. This tool became widely used across the entire software industry. Torvalds also created other specialized tools. One is Sparse, which is a static analysis tool for kernel developers. Another is Subsurface, which is software used for planning scuba dives.

Torvalds has received many prestigious honors for his technical contributions. In 2012, he won the Millennium Technology Prize. This award recognized his creation of a new open source operating system. He also received the IEEE Computer Society Computer Pioneer Award in 2014. In 2018, he was given the IEEE Masaru Ibuka Consumer Electronics Award.

In 1999, the MIT Technology Review named him one of the top 100 innovators under age 35. During that same year, his shares in companies like Red Hat and VA Linux briefly reached a value of about US$20 million.

While he is the creator, Torvalds does not write all the code himself. As of 2006, he had written approximately 2% of the Linux kernel. However, his role is more about authority and management. He acts as the final decision-maker for which code is merged into the standard kernel. He monitors the use of the Linux trademark through the Linux Mark Institute. This ensures the name is used correctly. He continues to work full-time on improving Linux through the Linux Foundation. This foundation supports his work to keep the kernel growing and stable.

Torvalds's career has also included personal growth and professional changes. He has been known for a blunt and sometimes difficult communication style on mailing lists. In 2018, he stepped away from the kernel for a time to seek help with his professional conduct. He apologized for past personal attacks, calling them unprofessional. He eventually returned to his work as a kernel maintainer. His life outside of coding includes a passion for scuba diving. He is married to Tove Torvalds, a six-time Finnish national karate champion. They have three daughters, and their birthdays are even used as special values in the Linux kernel's reboot system call.
