Desmontando um Playstation 3 e instalando Linux

Sexta-feira a noite, depois do futebol, sem muita coisa para se fazer resolvi brincar com o PS3.
Desmontei ele (não completamente, apenas algumas partes) e instalei Yellow Dog Linux 6.1 ppc64.
Abaixo seguem algumas imagens da brincadeira toda – desculpem a qualidade foi tirada num smartphone e por um amador em fotografias:

Basicamente a instalação de Linux no PS3 consiste em particionar o disco rígido para deixar espaço para as partições Linux.
Instalar o kboot (gerenciador de boot parecido com lilo/grub) que faz o PS3 inicializar.
A idéia principal era instalar na verdade o OpenBSD 4.4 macppc neste PS3.
Infelizmente as imagens do kernel do OpenBSD faziam o hardware simplesmente desligar.
Resolvi instalar o Yellow Dog mesmo.
Com o kboot instalado, reiniciar o PS3 em modo OS (o outro normal que inicia é o modo game).
Inicializar o DVD do Yellow Dog e mandar ver como qualquer instalação de Linux.
Detalhe negativo minha TV não ter HDMI e ser CRT ainda então resolução baixa e modo texto.
Até arrisquei modo gráfico mas… não ficou bom.
Bem, seguem mais dois links que foram as primeiras coisas que rodei no PS3 com Linux.

cat /proc/cpuinfo –> http://pastebin.com/f3c45d3e0

Bem, é isso. Conforme eu for avançando nos testes com esse hardware principalmente o Cell BE vou postando no blog.

Porque NÃO utilizar a RBL UCEProtect nos seus servidores de e-mail

OBS: nunca utilizei essa RBL, apenas algumas instituições fazem uso da mesma.

Motivos para não utilizar a RBL UCEProtect – http://www.uceprotect.net/

- Bloqueiam ranges de IP’s de forma adoidada, sem se preocupar com o resultado final (links importantes ficam a ver navios como se fossem links de spammers).

- Cobram 150 EUROS para remover “na faixa” o seu IP. 150 por IP, algo básico nos tempos atuais.

- Abaixo segue email-resposta da BrasilTelecom sobre a solicitação para remoção do range de IP’s indevidamente atingido pela famigerada “UCEProtect-Network”

Imagem do Email-Resposta da Brasil Telecom sobre o assunto (algo do tipo “como tirar o meu da reta”)

Se alguém mais tiver experiências com essa UCEProtect fique a vontade para fazer comentários.

E o pior motivo de todos Acaba com a sua paciência em plena sexta-feira
