Iceweasel is a fork Mozilla Firefox[1] with the following purpose :
1. backporting of security fixes to declared Debian stable version.
2. no inclusion of trademarked Mozilla artwork (because of #1 above)
Beyond that, they will be basically identical. (quoting Roberto C. Sanchez post in debian-devel mailing list)

Iceweasel’s (and Firefox’s) latest version, 4.0, was recently released[2], on Mach 22nd, and i’ve just upgraded Iceweasel 3.6 to Iceweasel 4.0 on my Debian Wheezy.

If you’d like to upgrade yours, follow the steps bellow.

1. Add Mozilla’s repository to sources.list
Edit the /etc/apt/sources.list file and add the repository’s address:

Even though it’s Squeeze’s repository, it worked fine on my Wheezy.
You can type the following command to add it:

2. Update packages list

3. Install Iceweasel 4
You can check the version of iceweasel with the command bellow:

Install it with the following command:

Wait for it to finish and happy surfing!

[git@pandora gitorious]$ crontab -e
cron/git: Permission denied

As the message says: it’s a permission problem. To solve this you’ll have to change /usr/bin/crontab‘s permissions:

And if that does not solve your problem, check /var/spool/cron/‘s permissions, they should match: drwxr-xr-x (755).

1 – Check your wireless card:
First of all we need to be sure that your wireless card is one of the BCMXXXX-based hardware:

The return should be something like this:
08:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01)

In that line you can see that my wireless card hardware is BCM4312, so it is supported.

2 – Download the Driver:
You can access Broadcom’s website[0] and download it or use wget to download it through shell.
For 32-bits CPUs:

For 64-bits CPUs:

3 – Remove the other modules:
Check if b43, b43legacy, ssb and/or an older version of wl modules exist:

Remove them, if they exist:

Add b43, b43legacy and ssb to the blacklist, preventing them to be probed in initialization:

4 – Install the wl module:
Extract the tarball you downloaded and compile it, you’ll need to install the build-essential package to compile it:

If you have an older version of wl, which is usually in /lib/modules//kernel/net/wireless, you should rename or remove it, to avoid conflicts:

Copy the new wl.ko to /lib/modules//kernel/net/wireless and install it:

Add it to /etc/modules to load it at boot time:

After these steps your wireless network should be working.

Troubleshooting
I had another problem: after rebooting, ssb module was being loaded even after being blacklisted, and the recently added wl module wasn’t.

To check if this is happening to you run the command below:

If the command returns something, it means that the ssb module is being loaded, then you’ll have to:

1 – Remove ssb and wl modules:

2 – Back up the current boot ramfs, generate a new one and reboot system:

3 – Reinstall wl module:

And wl module will be loaded at boot time.

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:

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/

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:

2 – Set execution permission:

3 – Download File:
There are two ways you can do this:
Passing the link as an argument:

You can also add more than one link:

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:

Then you run the script with the text file name as an argument:

You can create a link to the script in, or copy it to, the /usr/bin directory, making it executable from everywhere:

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.

Comprei, recentemente, o modem 3G da Claro, fabricado pela Huawei, modelo E226, e infelizmente não consegui fazê-lo funcionar de cara no Debian Lenny, mas após alguns minutos de pesquisa a solução apareceu!

A solução que descreverei também funcionou do Ubuntu, nas versões Intrepid Ibex e no Jaunty Jackalope.

Você precisará do pacote wvdial, instale-o com o comando:

Para saber mais detalhes sobre o pacote acesse este link: http://packages.debian.org/lenny/wvdial.

Após isso você deverá criar um arquivo de configuração para o wvdial, chamado wvdial.conf, com o seguinte conteúdo:

conecte-se com o comando:

E você estará conectado, mas ainda não será possível acessar qualquer endereço da internet, devido aos endereços dos servidores DNS estarem incorretos, então você deve adicionar as seguintes linhas ao arquivo /etc/resolv.conf:

Agora você poderá acessar a internet normalmente.

No Ubuntu, a configuração foi mais fácil devido à versão do network-manager, ao conectar o modem ao computador, este foi reconhecido normalmente e um assistente de configuração foi aberto automaticamente. Tudo o que tive que fazer para acessar a internet foi adicionar as linhas acima no arquivo /etc/resolv.conf após estar conectado, e deve ser após estar conectado porque o network-manager sobrescreve o arquivo /etc/resolv.conf toda vez.

Você pode, também, adicionar os endereços dos servidores DNS nas configurações da conexão da Claro no network-manager fazendo o seguinte: Sistemas > Conexões de Rede > Banda Larga Móvel > Editar conexão da Claro > Configurações IPv4 e adicionar os IPs 208.67.222.222, 208.67.220.220 na linha dos Servidores DNS e aplicar as alterações, assim você não terá que adicionar aquelas linhas no /etc/resolv.conf toda vez que conectar.

All you’ll need is the package vim-full, só, in Debian-like systems, you’ll need to execute:

Then, you’ll have to execute:

And you have it working!
NOTE: Depending on the version of your VIM, the path to less.vim might be different.

You can make this command simpler by creating an alias and adding it to your .bashrc file:

Now the system will need to re-read your .bashrc file, so the changes may be applied:

And after this you can test vless:

1 – Install most (http://www.jedsoft.org/most/index.html):
You can download most here: ftp://space.mit.edu/pub/davis/most/
or by executing the line bellow in debian-like systems:

2 – Export MANPAGER variable:
After this you’ll have to execute the line bellow:

Now you should have your man pages like this:

If you don’t want to export that variable everytime you restart your computer, you can add that line to your .bashrc file:

The first thing we have to do is to create the menu and it’s style:
Style:

Note that i didn’t set the a:visited style.

Menu:

Now we have our menu, but it’s still not showing what is the actual menu link, so we will need a function that will change the style of the actual menu link:

Javascript Function:

Now that we have the function it’s necessary to make it be executed after the menu is loaded, adding this line:

You could also create a class for the actual menu link and assign the class to the actual menu link, instead of setting the styles directly inside the javascript function, as shown below:

Actual Menu Link Class:

And the javascript function would change to:
JavaScript Function:

You can see the examples in the links below:
Using class
Not using class
The php codes are commented in the source.

Remeber that the pages must be .php .
