I’m super into selfhosting services! Rather than use Google Drive and MS Word for things, I run instances of similar open-source software on my home server. That way, I have terabytes of cloud storage accessible from anywhere, and can edit documents via any web browser with far less reliance on tech monopolies. As well as that, all my data is stored on my own hardware, so I’m in full control and giant companies can’t sift through it.
Shoutouts to !selfhosted@lemmy.world and !selfhost@lemmy.ml (and probably others I haven’t come across yet).
For anyone that’s interested: It’s not difficult to set up and you can use any old laptop you have lying around to host services.
Not exactly. The Neumann thrusters (and other similar electric propulsion units) provide little thrust, but are small and extremely (mass-)efficient. They carry a small amount of “fuel” (a small chunk of metal) on board which is burnt over a very long time to slowly de-orbit.
Because they’re small and efficient, it’s not difficult to attach one to a satellite and create a de-orbit plan rather than just leaving the spacecraft in space. In essence, these thrusters make the de-orbit process more feasible, leading to less stuff out in space in the future. And with spacecraft returning back to Earth, we can collect the remains, recycle them, and create new spacecraft. IMO it’s great for the sustainability of the space industry.
