Most of the time when you start to run a cyber cafe business, and one of the major part as cyber cafe purpose in service providing is a communication, besides email, instant messenger is one big thing that you must have it at your cyber cafe workstation, and Yahoo Messenger get a big part in instant messenger users, sadly for us who running an open source software didn’t get this attention from Yahoo Messenger developer, I’ve heard a rumors that Yahoo and Microsoft had an agreement or MOU to distribute Yahoo Messenger only for Windows platform.
But the FOSS community has come out with other alternative by making an alternative to Yahoo Messenger that’s can support all the YM features, it’s called Gyachi. According to the Gyachi website, the program is a fork from Gyach Enhanced Yahoo! client for Linux operating system. It was born purely out of impatience. Since there was no progress on Gyach Enhanced for about a year, a couple of impatient GYach Enhanced users decided to continue development of that client, fearing that original author Erica Andrews lost interest or abandoned project altogether. Therefore, in the true spirit of Open Source we, the developers, thought of simply “carrying on the torch”.[1]
This Yahoo! client for Linux operating system supports almost all of the features you would expect to find on the official Windows Yahoo! client: Voice chat, webcams, faders, ‘nicknames’, audibles, avatars, display images, and more. Yet, it remains very light-weight and memory-friendly. GyachE Improved uses Gtk-2 for its user interfaces (Gtk-2 2.0.6 or better required).[1]
I’ve try Gyachi before, although the interface is not smooth enough, I could say that Gyachi couldn’t attract my eyes enough to use it but the function works well. Between Gyachi and Pidgin interms for connection established, Gyachi is the winner for me, but right know, Pidgin still my best choice as instant messenger software for the moment.
