We all rely on the internet as a reference library. In those cases when you do not have access to the internet, it's pretty difficult to access the information you need. What if you could build a device that had the entirety of Wikipedia on it and you could connect to it with your phone no matter where you are? Let me show you my implementation of the Free and Open Source project Kiwix.
This is a pretty cool idea. The doomsday prepper in me has been thinking about this in a while. But I actually thought about a simple Pi with a Wi-Fi access point serving local Wikipedia wirelessly to mobile devices.
Because, you know, when the doomsday comes everybody will have a charged up mobile phone on them…
In what scenario would it be useful to be able to carry your own copy of Wikipedia a short distance and be able to read it for a few hours before the battery dies?
