In this video, Brian Kernighan discusses the history of the UNIX operating system, the C programming language, and his own work in computer science. He talks about the importance of simplicity in code, and how this has helped Unix become one of the most popular computing platforms of all time. Kernighan also discusses the advantages of working at Bell Labs in the 1970s and 1980s, and how this environment helped him to become a better programmer.

  • 00:00:00 Brian Kernighan discusses the creation of UNIX and C, which was a joint effort between himself and Dennis Ritchie. He also discusses his new book, which covers his life and work in computer science.
  • 00:05:00 This video discusses the history of the UNIX operating system, C programming language, and the Compatible Time Sharing System (CTSS). Kernighan explains that the original idea behind CTSS was to create an environment where multiple users could share a computer without each user knowing that others were working on the same task. Multics was meant to be a more powerful version of CTSS, and it offered a richer operating system environment. Kernighan believes that people at the time had the vision of what cloud computing is today.
  • 00:10:00 Brian Kernighan discusses the origins of Unix, and how it was not as successful as originally intended. He also talks about his time at Bell Labs and how it was a great place to learn about computers.
  • 00:15:00 Brian Kernighan discusses the challenges of writing an operating system, and how it takes a combination of creativity and experience to create something as complex as Unix. He credits Ken Thompson, the creator of Unix, with a large part of his success.
  • 00:20:00 Unix, C, AWK, AMPL, and Go programming are discussed in this video. Kernighan discusses the philosophy of Unix, how it made it easy to write code, and how it facilitated collaboration and innovation. He also mentions some of the advantages of working at Bell Labs in the 1970s and 1980s.
  • 00:25:00 Brian Kernighan discusses the importance of a feedback loop in computing, how Unix was created, and how its various features helped make it a successful operating system.
  • 00:30:00 Brian Kernighan discusses the efficiency of UNIX and how its simplicity helped it become one of the most popular computing platforms of all time. Kernighan also talks about the importance of programming being an art as well as a science, and how his process for writing code typically starts with experimentation and evolves into a more formal process over time.
  • 00:35:00 Brian Kernighan discusses the usefulness of the UNIX shell, awk, and grep programming languages, and how they can be used to explore data quickly and easily. He also describes some of the things that make these languages special.
  • 00:40:00 Brian Kernighan discusses the simplicity of searching through files and popping up naturally in UNIX and Linux environments, as well as the weight of history that Windows came from ms-dos. He also recommends whistle or whatever it's called as an editor for Windows users.
  • 00:45:00 In this video, Brian Kernighan discusses how programming languages started, how they evolved, and how they have become closer to the way humans think about code. He also mentions Fortran, COBOL, and Basic.
  • 00:50:00 This video discusses the history of programming languages, focusing on the development of the C language. The speaker notes that C was one of the most important languages in the history of programming, and that its popularity is due in part to its efficiency and expressiveness.
  • 00:55:00 Brian Kernighan discusses his work on the UNIX programming language C, along with AWK and AMPL, and Go. He also discusses his book "A First Course in Programming: With C" and how it helped teach programming to newbies. He comments on the wide range of programming languages available, and how Go stands out due to its practicality and Bell Labs heritage.
