InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
IMO the best use case is https://internet-in-a-box.org/. You download a bunch of stuff like Wikipedia, videos, books, etc, and any device with WiFi can access them. Much better than relying on something like a laptop or old phone with all of these resources on them. Get a couple of Raspberry Pi's and some SD cards and you can clone them all and have lots of backups. They are small and use little power so you can hide them in places that can't easily be found.
