Has Unix Programming Changed in 20 Years?
"What's the same is that Unix still works in essentially the same way. Processes are created with fork, the program the process runs is chosen by one of the exec calls, you open a file with open, and so on. Many—perhaps most—serious Unix programs access the Internet nowadays, and those system calls (socket, connect, and so on) are also nearly unchanged since they were introduced in BSD Unix in the 1980s. Even the primary implementation language, C, is largely unchanged, although it has grown up: Its standard has been revised a few times, and everybody now codes with function prototypes and without assuming anything about the size of integers and pointers."
