Mesa3D - Project Gallium Nine
I took this project abandonned by it’s developer and brough it from the dead to life. Although this project was technically challenging, I established an international group of developers and kept their motivation to develop and test product, report issues and actively contribute to the project.
2014 – 2015
iputils (ping & other network tools)
There is a many patches floating across all distributions applied to iputils package and after some failed trials to reach iputils maintainer, which time to time released new version without including all needed patches send to him, I moved project to Github, build CI and improved code quality. After short period of time I was able to convince all major distribution maintainer to join effort, contribute and use new upstream in the distributions. Big improvement which new iputils gained was unified ping (ping and ping6 merged together) – contribution from Pavel Šimerda.
