Let's create an Omnimaga Survival Package and list here what is inside. It contains stuff you *really* need, no matter where you are or what you are doing. but remember: we aren't normal!
let's start:

something against hunger. like batteries or peanuts, muffins, sunfish or lobsters.
a bootable device with an os of your choice. my choice is linux mint.
some calculators
something to read when you get bored (a printed version of one or more threads from here.
some magic in form of frienship
a firewall

and now your turn!
