Ngejunk post yang ringan-ringan...

Ternyata sistem APT di debian-based Linux punya easter eggs,
easter eggs mudahnya adalah pesan-pesan tersembunyi, joke/humor, feature yang terdapat dalam program komputer, halaman web, video, buku dan lain-lain yang sifatnya memang sengaja disisipkan oleh pembuat program (dalam hal program komputer)... http://en.wikipedia.org/wiki/Easter_egg_(media)
ini beberapa easter eggs dari apt yang ada,
$ aptitude moo
There are no Easter Eggs in this program.

~$ apt-get moo
