Reference : http://www.cyberciti.biz/faq/howto-ubuntu-linux-install-configure-jdk-jre/

The main steps are ->

Install the Java:

sudo apt-get install sun-java6-bin sun-java6-jre sun-java6-jdk

Setting up:

sudo update-java-alternatives -s java-6-sun
Insert  “/usr/lib/jvm/java-6-sun” in the of /etc/jvm using a text editor.
export JAVA_HOME=/usr/lib/jvm/java-6-sun
export PATH=$PATH:$JAVA_HOME/bin

Testing:

java –version

Create HelloWorld.java ->

public class HelloWorld {
    public static void main(String[] args) {
        System.out.println("Hello, World!");
    }
}

javac HelloWorld.java
java HelloWorld

That’s it!!

Now you will ask me : How?

The answer is below:

1 – Move your Maemo to the MMC internal

* Advantage : you will have more space.

Steps:  http://maemo.org/community/wiki/HowTo_EASILY_Boot_From_MMC_card/

Now you have the Maemo in the internal MMC.

2 -  Flash Mamona in your flash memory

* Advantage: Nowadays Mamona distro is good for developers.

Steps:  http://dev.openbossa.org/trac/mamona/wiki/Releases/0.1/RunningMamona

3 – Debian XFCE in external MMC

* Advantage:  Debian rocks !!

You should partition your MicroSD in 2 parts:

- partition 1 – 100MB – fat32

- partition 2 – ALL THE REST – ext2

Download the Debian rootfs

wget  http://debian.i2c3.com/debian-armel-n800-xfce-beta3.tar.bz2

Untar the Debian rootfs in the second partition:

tar -xvjf  debian-armel-n800-xfce-beta3.tar.bz2

Boot using your external MMC.

That’s all!!

Para que a placa de wireless funcione basta carregar o modulo iwl3945.

modprobe -r iwl3945
modprobe iwl3945

Para o modulo ser carregado durante o boot. Basta editar:

sudo vim /etc/modules

Adicionar ao final do arquivo:

iwl3945

No modo antigo era necessaria a utilização de firmware.

Este tutorial é para minha irmã que está em casa com o ubuntu instalado e não sabe muito de linux. Beijaum Karine!!!

Abrindo o terminal:

pressione (alt+f2) e digite “gnome-terminal” no janela que vai aparecer um terminal

Virando super-usuário:

Existem duas opções:

digite “su -” e quando ele perguntar a senha coloque a senha de root.

ou

digite “sudo su -” e quando ele perguntar a senha coloque a senha de root.

se o final do seu prompt mudou de “$” para “#”, então deu certo.

Instalando java:

digite “apt-get install sun-java5-jre sun-java5-fonts sun-java5-plugin”

ele deve fazer algumas perguntas sobre licença e você deve responder “yes”

update-java-alternatives –set java-1.5.0-sun

Feche o navegador e abra novamente.

Você pode testar o seu java plugin no site oficial da sun:

http://java.com/en/download/help/testvm.xml

Ou em um camera localizado na frente do nosso apartamento em Espoo/Finlandia.

Funciona perfeitamente no Debian.

Abaixou copiei o tutorial para ter um backup online.

Olá pessoal,
Aqui no meu trabalho tem algumas/várias impressoras espalhadas e escolhi um para configurar no Debian/Lenny.

Na minha opinião o configurador padrão do Gnome não é tão bom, por isto estou utilizando um outro configurador.

system-config-printer – printer configuration GUI

# apt-get install cupsys system-config-printer

Baixar drivers para impressoras Xeror no Linux

http://www.support.xerox.com/go/results.asp?Xtype=download&prodID=4500&Xlang=en_US&Xcntry=USA&source=XOG&prodName=Phaser%204500

Descompactar em área conhecida

tar -xvzf LinuxCupsPrinterPkg.tar.gz

Abrir o aplicativo

$ system-config-printer

tela 1 – Clique em New printer –>

tela 2 – Coloque o nome da impressora e clique em avancar –>

tela 3 – Selecione a impressora e clique em avançar –>

tela 4, 5 e 6- Selecione “Provide PPD file”, selecione drivers referente a impressora e clique em avançar –>

tela 7 – Confirmar criação de impressora –>

tela 8 – inserir senha de root–>

tela 9 – Printer1 pronta para imprimir–>

Abra o Gedit e teste um impressão qualquer.

PS: Configurar impressara Xeror Phaser 4500 é o mesmo princípio.

Recently I changed my desktop manager from Gnome to Fluxbox.

Good bye Gnome!!! Welcome Fluxbox!!

The reasons:
* lightweight
**working with kernel development and using a laptop, it’s really important.

* Highly configurable
**after many years, my gnome was very customized and the shortcuts are very familiar.

Below I describe the main steps.

Install and start fluxbox.

$ sudo apt-get install fluxbox

The first contact with fluxbox is really hard and the most difficult part is configure the shortlkeys.

alecrim@alecrim ~ $ cat .fluxbox/init | grep rootCommandsession.screen0.rootCommand: ~/.fluxbox/autostart.sh

Create you startup script. Below you can see mine.

==== Define background ====

I configure it using the fluxbox wiki howto.

$ fbsetbg -i

   display doesn't set the wallpaper properly. Transparency for fluxbox   and apps like aterm and xchat won't work right with it. Consider    installing feh, wmsetbg (from windowmaker) or Esetroot (from Eterm) and   I'll use them instead.

$ sudo apt-get install feh

...

$ fbsetbg -i

feh is a nice wallpapersetter. You won't have any problems.

$ fbsetbg -f  /home/alecrim/pessoal/image/paisagem/Grassy2.jpg

==== File manager ====

$ sudo apt-get install xfe

That’s all!!

Hi all,

I’m working with an OMAP1610 H2 and it was taking a long time to load and uncompress kernel. Eduardo recommended me some things to be done.

BE CAREFUL –
I’M NOT RESPONSIBLE FOR YOUR ACTS. YOU CAN MISS INFORMATION IF YOU DO NOT FOLLOW THE STEPS CORRECTLY.

1 – Upgrade u-boot

- Install scratchbox for cross-compilation.

- Download the last version of u-boot.

- Configure and Compile u-boot

[sbox-arm: ~/applications/u-boot-1.3.0] > make omap1610h2_config && make

- Copy the new u-boot.bin to your tftpboot directory(details here)

$ cp /scratchbox/users/alecrim/home/alecrim/applications/u-boot-1.3.0/u-boot.bin /tftpboot

- Using minicom, access the current u-boot prompt and load the new u-boot

OMAP1610 H2 # tftp 0×10000000 u-boot.bin
TFTP from server 10.0.0.1; our IP address is 10.0.0.2
Filename ‘u-boot.bin’.
Load address: 0×10000000
Loading: ###################
done
Bytes transferred = 93568 (16d80 hex)

The bold number is import, save it.IT’S YOUR U-BOOT HEXADECIMAL!!

- Unlock the flash memory, erase a sector, copy the new u-boot.bin and lock the flash again.

DANGEROUS!! TAKE CARE!!DANGEROUS!! TAKE CARE!!DANGEROUS!! TAKE CARE!!DANGEROUS!! TAKE CARE!!

REPLACE THE BOLD HEXADECIMAL (16d80)!!! PUT YOUR U-BOOT HEXADECIMAL !!!

OMAP1610 H2 # protect off 00000000 0001ffff
Un-Protected 1 sectors

OMAP1610 H2 # era 00000000 0001ffff

Erasing sector 0 … done
Erased 1 sectors

OMAP1610 H2 # cp.b 0×10000000 0×00000000 0x16d80
Copy to Flash…\done

OMAP1610 H2 # protect on 00000000 0001ffff
Protected 1 sectors
OMAP1610 H2 #

Now, you can restart your board and pray for some output on your serial.
