Finding Corporate Sponsors of Open Source

I copied about 19,000 git repositories into a full-text solr index. Because commits are tied to email addresses this provides interesting insight into corporate open source contributions. The search front-end I added lets you search for programmers or companies, grouped by the number of commits.

For example, searching for Linux returns the following results:

linux-foundation …………….
gmail …………..
redhat ……..
suse …….

 

Note that “gmail” indicates the use of @gmail.com addresses, so it’s non-company result. Searching for Android returns:

google …………………………………………………………..
android ………………….
gmail …..
elte
motorola ..
josefson ..
ziplinegames ..
suse ..
mosabuam ..
.google ..
davemloft ..
linux-foundation ..
sonyericsson ..
