Geralmente eu não gosto de ficar criando posts no meu blog só pra colocar links para matérias em outros sites, mas esta não dava pra deixar de lado. O fato do portal G1 publicar alguma coisa favorável ao Linux já é, em si só, uma notícia, que dirá uma matéria explicando ao público que o Linux não é um bicho de sete cabeças.
Especial Linux: saiba como trocar o Windows pelo Ubuntu em seu PC
Nem li a matéria ainda, mas parece ser o suficiente para um iniciante dar seus primeiros passos com o Ubuntu. Lembrando que é possível rodar o Ubuntu direto do CD, sem instalá-lo no seu computador, ou seja, se você quer apenas ver este tal de Linux para conhecê-lo, não precisa apagar nada da sua máquina. Com o mesmo CD é possível tanto testar o Ubuntu sem instalar, quanto instalá-lo, se assim quiser.
Linux is not Windows.

I remember reading somewhere recently (and my experiences in the past pay testament to it):
If you see a baffling problem, it’s surprising how often its down to DNS or host name resolving.
Basically, this guy updated Debian and then some app started behaving very slow when connecting with MySQL. Turns out it was a name resolution problem (DNS).
I remember some years back ago, when my Debian machine suddenly started taking several minutes or so to boot up, when previously it just booted in a minute or so. Turned out the problem was with exim (configured as local server only), which tried to resolve the machine name during start up, and because of some weird reason that I can’t remember now, the /etc/hosts file lost the entry for the own machine.
So here’s the lesson… if facing weird problems concerning suddenly, unexplainable slowness, check if the name resolution is working (DNS, hosts file, WINS, or whatever)
(and I just remembered that these issues give me a lot of headache with Tivoli Framework in several occasions…)
