An everyday laptop or the aging one it replaced both make good hosts for federated wiki, one because you have it with you, the other because it can stay put out of the way.
Content developed on a laptop can be forked into more public servers.
Content developed for personal use can be confined to the laptop. I run wiki as a farm and use localhost as the domain name for personal content.
Laptop Server describes trying wiki from a laptop.
An experimental server can be run from a terminal window. If it stops, restart it.
The 'screen' program is handy for running servers that you occasionally want to watch.
Start a new screen named 'wiki'.
screen -S wiki
Launch wiki. Detach the screen with control characters typed without stopping wiki.
^AD
Resume the screen at a later time.
screen -r wiki
Even an aging laptop battery will keep the server running through storm related power failures. This makes more exotic daemon startup logic unnecessary.
