This is a podcast dedicated to learning the "classic" version of the C Programming language from the 1978 book written by Brian W. Kernighan and Dennis M. Ritchie. This book places the reader right in the middle of the 1970's transition from a hardware-centered computer science to a focus on writing portable and efficient software. C was used to develop operating systems like Unix, Minix, and Linux. Programming languages like Python, Perl, Java, JavaScript and Ruby are all written in C. Software like the early TCP/IP networking implementations that made the Internet possible were written in C. And the first web browsers were written in C. C made major advances in computer architecture possible because operating systems, compilers, and utilities could be re-compiled on a new architecture once they built a C compiler for the architecture. So there is a very good chance that almost all the software that you use was either written in C or written in a programming language that was written in C. So we study C less as a programming language to use on a daily basis and more as the foundation of modern software and computing.
