#9 Perl

Perl is a family of high-level, general-purpose, interpreted, dynamic programming languages. The languages in this family include Perl 5 and Perl 6.

The Perl languages borrow features from other programming languages including C, shell scripting (sh), AWK, and sed. They provide powerful text processing facilities without the arbitrary data-length limits of many contemporary Unix tools, facilitating easy manipulation of text files.

Perl was very popular in the 90s for its ability to create CGI scripts that beefed up the functionality of early Web pages. In addition to Web development, it's used for things like system administration, building desktop apps, game development and even bioinformatics.

#8 C

C is one of the most widely used programming languages of all time, and C compilers are available for the majority of available computer architectures and operating systems. Many later languages have borrowed directly or indirectly from C, including C#, D, Go, Java, JavaScript, Limbo, LPC, Perl, PHP, Python, and Unix's C shell. It may lack the look of the latest Web development frameworks, but C is what lots of operating systems, kernel level software and hardware drivers are made of.
