Quickstart info : what I need to know to get the knack on puppy in 10 minutes

which boot media to choose for puppy (stick, CD) ?

There are distinct advantages from running from CD that are not so readily present with other systems.
The main one is integrity of data. A computer running from CD without the internet connection activated is very secure.
running from stick gives you an easily detachable fast system, that does not mess with anything on your harddisk. boot-up time between stick and multisession CD is comparable. of course a CD-RW is cheaper than a stick. In both cases you get a complete, bootable, writeable Linux on a single piece of removeable media :-)

your Config and downloaded files (i.e. your homedir /root together with /root/.usr) can be stored anywhere e.g.
* on the disk
* on a USB
* a floppy
* or the HD
by copying the pup001 file (internally an ext2 fs) from e.g. Windows as a backup. pup001 keeps all your individual data.

I liked the DidiWiki (25k of C code) and wrote to the author asking
about a p2pWiki (no such thing at the present time . . .)

Here is how it works:

1. When you open the wiki - it downloads an update from any of your trusted fellow wikians
(contacting them in order of priority as set by you) - without going through a server - that is p2p

2. you edit the wiki and leave it open until such time as it has been downloaded by (set number of nodes)

3. Whilst you are editing the page is locked - or if locked unavailable for editing

4. This means every user carries the whole of the wiki on their machine and it is updated everytime they use it.

just an idea
