All Ubuntu codenames are came from in the form of “Adjective Animal” and it is in alphabetic order from the third release onwards. The first two releases are not on the alphabetic order.
In his post, Mark explains that with Ubuntu 14.10 Utopic Unicorn, it’s “time to bring systemd to the centre of Ubuntu, time to untwist ourselves from Python 2.x and time to walk a little uphill and, thereby, upstream. Time to purge the ugsome and prune the unusable“.
Ubuntu 14.04 will be released on October 2014. Came with more updated Unity 8, the convergence between mobile world and desktop world etc. are the promises. We will face another shaky release but expecting new features.
The word ‘Utopic‘ is derived from ‘Utopia‘. The Unicorn is an animal from mythology generally depicted as Equidae with a lone, long spiralled horn on their heads.
