from BlackBeltJones. Warchalking is a proposed graffiti language for pointing to wireless hubs in the city. It’s an extension of wardialing (the old hacker practice of phoning numbers to see what’s on the other end) and wardriving – driving around to find wireless (802.11b) access points – merged with the old hobo symbols that were used to let others know of dangers or good things in an area.
