for all the people saying smart devices/homes, you all should check out rhasspy/piper on github. It by itself is a TTS system but it's integrated into an offline smart-home system and a few other projects in the same vein. The links are on their git page and its pretty damn interesting. I personally use it for audiobooks after training my own voice but a lot of people want an amazon/google alternative. I may or may not have just trained a model on the same voice that amzn uses lol.
I mean "nothing" is beneficial to the planet besides just stopping dumping CO2 into the air and toxic bs into the land and ocean. There is NO substitute for stopping corporate pollution, I mean nothing. That said, electric cars have more perks than just environmental impact, they do marginally help and they're cool. but in reality, you have to learn to tease apart what actual climate action looks like VS corporate adoption of "green washing" their products and putting the responsibility on the avg citizen. But that is infinitely hard for some people to come to realize.
Stavros is the best
I wrote a nice little CLI tool that lets you browse the flatpak store in the terminal and has an option to link all your flatpaks to their short names. Its really just a wrapper bash script that runs flatpak, but I like it because it goes from com.Blender.Blender to just "blender" and it works on the command line.
