<hecker> cool ein Ada Lovelace Google-Doodle. aber zum 197. Geburtstag? Hätten
die nicht noch 3 Jahre warten können? <mirabilos> bis dahin gibts google nicht
mehr <hecker> ja, könnte man meinen. wahrscheinlich ist der angekündigte welt-
untergang aus dem maya-kalender die globale abschaltung von google ☺ und darum
müssen die die doodles vorher noch raushauen
