For secrets management, I basically just use fnox everywhere (https://fnox.jdx.dev/). It's a frontend to tons more options than sops, although `age` is still included. I also think the DX is better but to each their own.
I spent ~5 years volunteering for a search and rescue team in New Mexico.
We definitely got the cellphone tower triangulation data. I never once saw GNSS data provided by a carrier. We used FindMeSAR https://findmesar.com/, the subject would usually text back the coordinates from the phone.
Just one data point.
The revolution that's occurred since my SAR volunteer days is the wide availability of satellite messenging on consumer phones. I'm guessing that's really changed the situation quite a bit.
>assuming you have formalized the statement correctly
That's a pretty big assumption, though, isn't it? As we saw the Navier-Stokes psychosis episode over the New Year holiday, formalizing correctly really isn't guaranteed.
I recently created a Matrix channel for my open-source project. It's really quite good. They need to work on the threading (I prefer Slack's model), but really it's 90% as good as Slack for my use case of an OSS community.
