Per coloro che hanno un sito o un blog e vorrebbero comprendere quale possa essere il valore della loro "creatura"....

Abakus is a simple calculator for KDE, based on a concept of Roberto Alsina's. Think of it as bc (the command-line calculator) with a nice GUI. Abakus wasn't the only calculator to be developed due to Roberto's brainstorm. You may also want to try Ariya Hidayat's SpeedCrunch (maintained/improved by Johan Thelin). In fact many of Abakus's user interface niceties were donated from SpeedCrunch.
