The trends we consider include: 1) the relative popularity of the ten most popular programming languages over time, 2) the use of multiple programming languages by individual programmers and by individual projects, and 3) the programming languages most often used in combination. %B 2nd Workshop on Public Data about Software Development (WoPDaSD 2007) %> https://flosshub.org/sites/flosshub.org/files/Delorey2007b.pdf
