Looking for recommendations from the HN community on where one would start.<p>On the technical side I'm interested in suggestions regarding:<p>* Open Source / Community Projects<p>* Companies / Organisations / Startups working on promising innovative research or products in disruptive sustainability<p>On the community / activist side, I'm looking for:<p>* Activist groups that lobby for change and sustainable practices, where computer science skills might be able to contribute<p>* EU / UN projects where such a skillset might be useful<p>Any other general advice welcome. I'm tired of writing code for ad-tech while the world burns, and I suspect there are others like me who would like to get more involved, hence this post.
