Como Venezolano debo decir que lamento mucho lo sucedido en el país por la tragedia de Amuay, esto es solo un signo de como el poder en manos incompetentes mas la mala suerte, por que nadie quiere que algo tan horrible suceda (me gusta creer eso) pueden ocasionar tales agravios.

Numero 1 nuevamente

 El Gran libro de Debian GNU/Linux  regresa a la posición numero 1 del top de los mas vendidos de Amazon Espana. Hemos vuelto por tercera vez y esta vez tenemos mas de un par de horas alli, para los que no lo saben el top 100 de Amazon se actualiza por hora así que prácticamente el chequeo de la posición del libro es un ticket que siempre esta en mi bandeja [If you know what i mean]. Para cerrar y celebrar les dejo este enlace a un show estilo TV de Drumb & Bass que estoy escuchando últimamente y si les gusta la música electrónica no deben dejar de probar. Feliz fin de semana y gracias por el apoyo.

OpenIndiana Installation

OK  so a friend of OA ask me to write  an article about SmartOS, seriously i try but i don’t know what its up whit the  ISO file of that project that wont boot up! i mean i download from this server a file call «latest.iso» it didn’t boot… later on i download another ISO file, an older version this time, the version was (20120726T184637Z). and it didn’t boot up either, so i decided to not leave the things like that and went to a similar project named OpenIndiana, is almost the same thing. BTW i am guessing that my friend want an article about this… because first there is like ahhhhh ZERO documentation, second he has to be focusing on Visualization technology. We are going to make some articles about that but not with SmartOS. Fare well lets start this installation walk trough.
