What are some good technology projects to donate to in 2015?

As part of my new year resolution, I tend to donate (a small) something to a particular project. Last year it was OpenSSH, especially because I read that it was one of those important projects that doesnt get any support.

The year before it was Wikipedia and Wikileaks.

What are some technology projects that are worth supporting this year ? P.S. Yes- I also donate to other humanitarian causes. This question is going to be only around technology projects. If the technology in question is related to a humanitarian cause, then so be it.
