Creating Web Albums with gThumb
Posted by Éverton Arruda in Free Software, Linux, Planet INdT, Planet PSL-AM, Tutorial, Web on December 4th, 2009
If you want to create a web album with some images you have in your computer, with Linux as your OS, i recommend you to use gThumb.
gThumb is, as said in WikiPedia (http://en.wikipedia.org/wiki/GThumb):
… an open-source image viewer and organizer for the GNOME desktop environment released under the GNU General Public License. It was originally based on GQView, and is designed to have a clean, simple interface.
gThumb Homepage: http://gthumb.sourceforge.net/
INSTALLING GTHUMB:
I’m using Ubuntu 9.04, named Jaunty Jackalope, to write this tutorial, so the installation process is very simple, all you have to do is run:
1 | # aptitude install gthumb |
This should work the same way for Debian GNU/Linux, but if you’re using another distro Linux, you might have to compile gThumb.
CREATING WEB ALBUM:
When you run gThumb you’ll see this interface:
I mapped it to make it easier to follow:
The steps to create the Web Album are:
1 – Create directory to keep the images:
First create a directory and put the images you’d like to be in the album in it.
2 – Open directory with gThumb:
In gThumb interface, select the directory in which the images are (#1 in MAP)
3 – Select the images you’d like to show in the album:
After opening the directory, which contains the images, you’ll have to select the images you’d like to show in the album (#2 in MAP)
4 – Open the “Create Web Album” window and configure it:
Now, with all images selected, go to Tools > Create Web Album (#3 in MAP)
Then you should see a window like this:
![]()
This is where you’ll configure your web album. The options are:
#1 – Where the web album files will be saved.
#2 – The name of the page, i recommend you to leave it as it is.
#3 – How many images per line and per column will be shown.
#4 – The title of the page, or header message, if you preffer.
#5 – The footer message of the page.
#6 – The theme that will be used in the web album.
The other options are not so important for me, so i didn’t put them in here.
In the end, you’ll have something like this: http://am.softwarelivre.org/galeria/fedora12releaseparty/

Highlighting “@all” in XChat2
Posted by Éverton Arruda in Free Software, Linux, Planet INdT, Planet PSL-AM on November 9th, 2009
For some time i tried to highlight the “@all” string in XChat2[0], an IRC client, but when the XChat2 highlight feature reads the “all” word, it highlights all messages, in all channels.
Fortunately, i found a python script that highlights defined strings, and it works great for me. The script name is hilight-phrase, you can find it at ctrl+d blog[1].

IpForward from Computer with Linux to PS3
Posted by Éverton Arruda in Linux, Planet INdT, Planet PSL-AM, Tutorial on October 13th, 2009
I’ve recently bought my PlayStation 3 (FInaly!!!!!) and was thinking of a way to connect my PS3 to the internet using my 3G BroadBand internet connection, which is provided by the brazilian Phone Company Claro. The only thing that came to me was: IpForward.
So i did this:
1 – Connected my Notebook to the 3G Broadband:
Just connected as I normally do.
2 – Connected my PS3 to my Notebook:
Created a LAN between them, through my notebook’s interface eth0.
I configured my PS3’s network connection as follows:
In the PS3’s main menu go to Settings > Network Settings > Internet Connection Settings, then, go through this sequence of choices: custom, wired connection, auto-detect, manual (the ip settings are shown bellow), automatic, do not use (in my case i don’t use any proxy), enable.
The Ip Settings are:
Ip address: 192.168.0.2
Subnet mask: 255.255.255.0
Default Router: 192.168.0.1 (This is my Notebook’s Ip)
Primary DNS: 208.67.222.222 (This is Claro’s primary DNS Server)
Secondary DNS: 208.67.220.220 (This is Claro’s secondary DNS Server)
3 – Set Notebook to IpForward
I found a Script in the internet that does everything it needs to ipforward, all i did was add the final line, which sets a fixed ip to the interface that is connected to the LAN. I don’t remeber who wrote the script, but the credits are his/hers.
All you have to do now is save the script bellow and run it everytime you want to connect your PS3:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | #!/bin/sh # Basic firewall and forward/masquerade setup PATH=/usr/sbin:/sbin:/bin:/usr/bin # Delete/Flush old iptables rules iptables -F iptables -t nat -F iptables -X # Set up IP FORWARDing and Masquerading iptables --table nat --append POSTROUTING --out-interface ppp0 -j MASQUERADE echo "1" > /proc/sys/net/ipv4/ip_forward ifconfig eth0 192.168.0.1 netmask 255.255.255.0 |
If you did as it is described in here, then it should work just fine.
Just for the record, I’m sing BrDesktop Lenny Linux as Operating System (a Debian Pure Blend).
Note: Everytime I try to test the connect through PS3, my notebook loses the ip 192.168.0.1 and starts o search for another one, breaking the connection between them. So i recommend you not to use that feature when using the connection method described in here.

GooSH.org, my new start page
Posted by Éverton Arruda in Free Software, Linux, Planet INdT, Planet PSL-AM, Web on September 25th, 2009
A friend sent me a link to a webpage, the link was: http://goosh.org. Right after accessing the webpage i decided: “This is going to be my new start page”.
GooSH stands for Google Shell, it is an unofficial Google Product. Written by Stefan Grothkopp, it simulates a Unix Shell with access to some Google Products, simply fantastic!
I recommend it for everyone!
Downloading files from Rapidshare through shell
Posted by Éverton Arruda in Free Software, Linux, Planet INdT, Planet PSL-AM, Tutorial on September 25th, 2009
I’ve seen, at Viva o Linux (http://www.vivaolinux.com.br, in portuguese), a post talking about a ShellScript that downloads files from RapidShare through shell. As, sometimes, i download files from that site, i decided to try it out and it worked fine for me.
This script uses wget to download the first html page, then it gets the link to the page that contains the link to the file, download this second page, checks the timer and waits for it to finish, after it finishes, the script starts the file download. I noticed that, if the download stops, this script continues from where it stopped.
This is how it goes:
1 – Download the ShellScript:
1 | $ wget http://tokland.googlecode.com/svn/trunk/rapidshare/rapidshare-dl.sh |
2 – Set execution permission:
1 | $ chmod +x rapidshare-dl.sh |
3 – Download File:
There are two ways you can do this:
Passing the link as an argument:
1 | $ ./rapidshare-dl.sh http://link.to.rapidshare |
You can also add more than one link:
1 | $ ./rapidshare-dl.sh http://link.to.rapidshare http://another.link.to.rapidshare |
Passing a text file as an argument:
Create a text file, named links.txt for example, and put each link in a different line, like:
1 2 3 | http://link1.to.rapidshare http://link2.to.rapidshare http://link3.to.rapidshare |
Then you run the script with the text file name as an argument:
1 | $ ./rapidshare-dl.sh links.txt |
You can create a link to the script in, or copy it to, the /usr/bin directory, making it executable from everywhere:
1 | # ln -s $PATH_TO_SCRIPT/rapidshare-dl.sh /usr/bin/rapidshare-dl |
1 | # cp rapidshare-dl.sh /usr/bin/rapidshare-dl |
NOTE: This script works only in Unix-like systems.
There is also plowshare, which is another shellscript that does the same thing, and more, but i haven’t tested it yet. In the project page it says that it supports Megaupload, Rapidshare, 2Shared, 4Shared, ZShare, Badongo, DepositFiles and Mediafire, and it also uploads files to those share sites.

Microsoft vs General Motors
Posted by Éverton Arruda in Etc, Planet INdT, Planet PSL-AM on September 18th, 2009
Hoje, eu estava lendo um fórum do qual participo e vi um tópico que me chamou a atenção, este intitulava-se: “Microsoft vs General Motors“. Achei o texto fantástico e precisava mostrá-lo a mais pessoas, então decidi postá-lo. Abaixo segue o texto:
Numa recente feira de informática (COMDEX), Bill Gates fez uma infeliz comparação da Indústria de computadores com a automobilística e declarou:
“Se a GM tivesse evoluído tecnologicamente tanto quanto a indústria de computadores evoluiu, estaríamos todos dirigindo carros que custariam 25 dólares e que fariam 1000 milhas por galão (algo como 420km/l)”.A General Motors, respondendo “na bucha”, divulgou o seguinte comentário a respeito desta declaração: SE A MICROSOFT FABRICASSE CARROS:
1 ) Toda vez que eles repintassem as linhas das estradas você teria que comprar um carro novo.
2 ) Ocasionalmente, dirigindo a 100 Km/h, seu carro,de repente, morreria na auto-estrada sem nenhuma razão aparente, e você teria apenas que aceitar isso, religá-lo (desligar o carro, tirar a chave do contato, fechar o vidro, sair do carro, fechar e trancar a porta, abrir e entrar no carro, sentar-se ao banco, abrir o vidro, colocar a chave no contato e ligar) e seguir adiante.
3 ) Ocasionalmente, a execução de uma manobra à esquerda, poderia fazer com que seu carro parasse e falhasse. Você teria então que reinstalar o motor! Por alguma estranha razão, você aceitaria isso também.
4 ) A Apple faria um carro em parceria com a Sun, confiável, cinco vezes mais rápido e dez vezes mais fácil de dirigir. Mas apenas poderia rodar em 5% das estradas.
5 ) Os indicadores luminosos de falta de óleo, gasolina e bateria seriam substituídos pôr um simples “Falha Geral ou Defeito Genérico”.
6 ) Os novos assentos obrigariam a todos terem o mesmo tamanho “default” de bumbum.
7 ) Em um acidente, o sistema de airbag perguntaria: “Você tem certeza que quer usar o air bag?”, antes de entrar em ação.
8 ) No meio de uma descida pronunciada, quando você ligar o ar condicionado, o rádio e as luzes ao mesmo tempo, ao pisar o freio apareceria uma mensagem do tipo “Este Carro realizou uma operação ilegal e será desligado”!
9 ) Se desligar o seu Carro 98 utilizando a chave, sem antes ter desligado o radio ou o pisca-alerta, quando for ligá-lo novamente, ele iria checar todas as funções do carro durante meia hora, e ainda lhe daria uma bronca para não fazê-lo novamente.
10 ) A cada novo lançamento de carro, você teria que reaprender a dirigir, voltar à auto-escola e tirar uma nova carteira de motorista.
11 ) Para DESLIGAR seu carro, você teria que apertar o botão “Iniciar”(????)

O objetivo desta celebração é educar o publico mundial sobre todos os benefícios de se utilizar Softwares Livres e de Código Aberto de alta qualidade na educação, no governo, em casa e nos negócios — em resumo, em todo lugar! A organização sem fins lucrativos Software Freedom International coordena o Software Freedom Day a nível global, dando suporte, brindes e um ponto de colaboração, mas times voluntários em todo o mundo organizam os eventos locais para impactar as suas próprias comunidades.
Em Manaus, o evento será realizado para divulgar a criação do PSL-AM, Projeto Software Livre – Amazonas, que irá, através de palestras em várias universidades, simultaneamente, divulgar o Software Livre e Open Source e explicar mais sobre esse mundo Livre e onde o PSL se encaixa neste assunto.
Away++ XChat2 Plugin
Posted by Éverton Arruda in Free Software, News, Planet PSL-AM on September 3rd, 2009
I’ve created a page named Development, where i’ll put some tools, scripts and softwares made by me, or in which i had a hand on.
To start that page, i put a plugin for XChat2, named Away++. It changes your nick to an away-nick when you set your status to away and changes your nick back and identifies it when you set your status to back.
