Litterate Programming --------------------- Write throw-away code and it will become production code Enterprise Expect ----------------- Because you always know what you want, `expect(3)` script code can be replaced by a `subshell and pipe` pattern : <code> ( echo "$username"; sleep 1; echo "$password"; sleep 1; echo "cp old new" ) | telnet </code> painload example: `//retiolum/bin/announce_pubkey` Enterprise Waiting ------------------ Quietly wait until someone else solves the problem.
