The Open Source Census is the first collaborative, global project to count the number of installations for each open source software package. We realize that’s pretty ambitious, but we figure you have to think big. Of course, we know we can’t count every single installation of open source software in the world, but we believe it’s possible to obtain a sample large enough to be representative.
