<<detournement>>: Cultural hijacking. Taking something that has a usual meaning and making it play your way. A detournement is a cultural <<hack>>.
<<dharma combat>>: Wrangling over standards and protocols, as in the <<IETF>>. Dharma is Buddhist for the principles of operation for the universe. Lots of <<deep geeks>> are Buddhists, Buddhist-wannabes, or jack-Buddhists.
<<digital cash>>: The Philosopher's Stone of the nineties. Or maybe the Brooklyn Bridge. And good luck with it.
<<diy>>: Do it yourself. A part of haqr mind, see Chapter Eight.
<<domain name>>: This is part of the eddress that humans use. If you subscribe to an online service, like US Online, your domain eddress is theirs. Your whole eddress is whatever your handle is— say skulldrool— plus the server's domain name, like so: skulldrool@usol.com. Top level domain names are countries, like .au for australia, or categories, like .com, for company, .org for organization, .gov for the government, .mil for the military, etc. Domain names can be bought, and maybe they can be hacked. For example, if I had a military-industrial complex, I might hack an eddress like dark.satanic.mil.
<<dot.plan>>: This is a file in your home directory within UNIX that people can read when they <<finger>> you. Your dot.plan file (actually it's just .plan) is where you put your advertisements for yourself. A typical dot.plan might start with a motto or a fave quote, such as, "In theory, there's no difference between theory and practice. But in practice, there is." Followed by as intriguing and flattering a profile of yourself as you can whomp together.
<<dot.sig>>: This is your online signature, your digigraph, which you can tack onto the end of all your online appearances. A dot.sig is usually made up of thought-provoking quotes and ascii graphics. While somebody has to <<finger>> you to get your <<dot.plan>>, everybody is forced to see your dot.sig every time they read your postings or get email from you. Think of your dot.sig as a billboard advertising yourself.
