Novos Brinquedinhos - HP-UX Solaris Itanium 2

Chegaram hoje as máquinas que faltavam para completar meu home office.

Na Figura abaixo podemos ver todas elas:



Da esquerda para direito temos:

1 . Wokstation HP ZX2000 com processador Itanium 2 1.1 GHZ.
Esta máquina suporta HP-UX, Linux e Windows para IA64.
Aqui irei fazer dual boot (ou tri-boot, não sei como dizer) com todos
estes sistemas operacionais.

2. Workstation HP c3700 com 2 processadores PA-RISC 550 MHZ.
Esta máquina suporta HP-UX e Linux. No entanto, só irei rodar HP-UX.
Isso porque não existe demanda comercial para Linux em PA-RISC.

3. Workstation Sun Blade 100 cada uma com 1 processador Sparc 550 MHZ.
Podemos rodar Solaris e Linux mas o objetivo aqui é executar somente Solaris.
Tal como o Linux para PA-RISC não tenho demanda para desenvolvimento
ou customizações em Linux Sparc.

Infelizmente nesta semana não terei tempo de ligar nenhuma máquina.
Meu tempo é meio curto e é bem possível que apenas irei dedicar tempo quando surgir demanda
para cada uma delas. Afinal, não estou mais na universidade e não tenho disponibilidade para ficar "brincando".
Mas na medida que for colocando para funcionar irei postar mais detalhes de cada máquina.

Gerando Imagens ISO do CD/DVD no Mac OS X

Neste post irei explicar como gerar uma imagem ISO de seu CD/DVD usando a linha de comando (terminal) no Mac OS X

Passo 1: Insira o CD/DVD do qual deseja gerar a imagem

Passo 2: Inicie uma instância do Terminal. Normalmente encontrado em Application\Utilities\Terminal

Passo 3: Verifique qual dispositivo o drive de CD/DVD esta usando. Para isso execute o seguinte comando:

$ drutil status
Vendor Product Rev
MATSHITA DVD-R UJ-857E ZA0E

Type: DVD-ROM Name: /dev/disk2
Sessions: 1 Tracks: 1
Overwritable: 00:00:00 blocks: 0 / 0.00MB / 0.00MiB
Space Free: 00:00:00 blocks: 0 / 0.00MB / 0.00MiB
Space Used: 274:44:52 blocks: 1236352 / 2.53GB / 2.36GiB
Writability:
Book Type: DVD-ROM (v1)

Observe na saida do comando que em meu caso o nome do dispositivo (marcado em negrito) é /dev/disk2. Preste atenção nesta informação pois ela será usada pelos comandos seguintes.

Passo 4: "Desmonte" o dispositivo com o seguinte comando:

$ diskutil unmountDisk /dev/disk2
Unmount of all volumes on disk2 was successful

Passo 5: Criar a imagem ISO usando o comando DD. Esta operação pode demorar.
Por isso tenha paciência e espere a finalização do comando.
O comando a ser usado é:

$ dd if=/dev/disk2 of=imagem.iso bs=2048
1236352+0 records in
1236352+0 records out
2532048896 bytes transferred in 755.615869 secs (3350974 bytes/sec)

Passo 6: Teste a operação montando a imagem gerada (ou abra pelo finder).
$ hdid imagem.iso

Neste momento você ja deve ter a imagem do seu cd/dvd gravado no arquivo imagem.iso.

Problema: error C2011: 'fd_set' : 'struct' type redefinition

Esta ai mais uma merdinha do Visual Studio 2003.
Ao compilar um de meus projetos fui presentiado com zilhões de mensagens de erro.
A primeira delas é a do título deste post. Outras mensagens podem ser vistas no final deste post.
E ai, como resolver isso ?
O problema era que estava incluindo o windows.h antes de winsock2.h.
Para resolver este problema basta trocar a ordem na inclusão dos arquivos.

Dando uma pesquisada maior parece que windows.h ja inclui winsock2.h.
Por isso o problema de redefinição de tipos.
Mas agora não estou no ambiente e não posso testar.

Problema: "The project file ' ' has been renamed or is no longer in the solution"

Agora a pouco ao tentar compilar um projeto no Visual Studio 2003 me deparei com este erro.
Legal né ? Poucas vezes vi uma mensagem de erro tão imunda e inútil como essa.
Bom no meu caso o problema era uma referência não encontrada um dos projetos.

Tinha esquecido de fazer o checkout e o Visual Studio não reclamou ao abrir o Solution.
O que você tem que fazer é verificar em todos os projetos do Solution qual deles possui uma referência não encontrada.
Na figura abaixo mostro um screenshot de como o problema deve aparecer.



A solução é fazer o checkout do projeto ou se ele não for mais necessário, eliminar a referência para o projeto.
