From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Also really easy to introduce bugs. But from how everyone online talks about being good developers is all you need. I don't know how those bugs get there in the first place.
Easy to explain.
Visualizing program code as cables, this is how a shiny new program would look:
And this how, for example in a commercial environment, or if the programmers are not absolute masters, such a program will look after 15 years of bug fixing, feature requests, urgent changes, deadlines, and unfinished restructurings:
The thing is that especially C code contains tons of implicit invariants which you simply cannot maintain in such code.
And don't forgot that the picture above shows perhaps 500 cables, but a codebase can easily contain 50000 lines of code....
