I am going to talk about a little problem that I found installing Compiz over Ubuntu in my laptop. There are graphic cards in a Compiz Blacklist, because of they did not enough tested, or did not use standards, with Compiz can grant a good software performance. Treating to see the 3D Compiz-fusion Desktop on Linux, I installed Ubuntu in my new laptop:

• ASUS Z53E
• Ubuntu 7.10
• Graphics: Intel X3100

The Ubuntu installation process, brilliant. With the LiveCD a guided installation. Ubuntu was installed in 20 minutes. !! But the brand-new Desktop effects did not installed ¡¡ In the menu option System > Preferences > Aparience > Visual effects we must mark the "Extra" choice to work with 3D effects. But when I marked the option shows the error: "Desktop effects could not be enabled". This was because of my graphic card (intel x3100) is in the Compiz Blacklist, as you can read at this post: http://ubuntuforums.org/showthread.php?t=582112. To solve it then go off the Blacklist:

mkdir -p ~/.config/compiz/ && echo SKIP_CHECKS=yes >> ~/.config/compiz/compiz-manager

Then we have the 3D effects. But if we want to tune them, we need:

• A settings manager (compizconfig-settings-manager): Where I will configure what effects I want to show.
• A them manager (Emerald): We can tune our Desktop, with the themes in compiz repository: http://www.compiz-themes.org.

This utilities are installing from the command line as I type:

sudo apt-get install compizconfig-settings-manager emerald

We have both at System > Preferences. If you want a reference about compiz-fusion, or learn the utilization, you can access to Compiz wiki: http://wiki.compiz-fusion.org/

Os voy a relatar el problemilla que encontré instalando Compiz sobre Ubuntu en mi portátil. Hay tarjetas gráficas que están en la Lista Negra de compiz por no estar los suficientemente testeadas ó no obedecer a estándares, sobre los que poder asegurar un correcto funcionamiento del software. Tratando de ver el escritorio 3D de compiz-fusion para linux, instalé ubuntu en mi portátil nuevo:

• ASUS Z53E
• Ubuntu 7.10
• Gráfica: Intel X3100

La instalación de Ubuntu genial, desde el LiveCD y muy bien guiada, hasta me deje auto-particionar el disco. En 20 minutos tenia Ubuntu en el disco duro. !! Pero los flamantes efectos de escritorio no se instalaron ¡¡ En el menú Sistema > Preferencias > Apariencia > Efectos Visuales debemos marcar la opción "Extra" para tener todos los efectos 3D. Pero al intentar marcar saltaba el error: "Desktop effects could not be enabled". Esto sucedía por que mi tarjeta gráfica (intel x3100) está en la Blacklist de Compiz como bien se explica en este post: http://ubuntuforums.org/showthread.php?t=582112. Para solucionarlo, puentear la lista:

mkdir -p ~/.config/compiz/ && echo SKIP_CHECKS=yes >> ~/.config/compiz/compiz-manager

Con esto tenemos los efectos 3D. Pero para personalizarlos necesitamos:

• Un Gestor de Preferencias (compizconfig-settings-manager): En el que le podemos decir exactamente que efecto queremos reproducir.
• Un Gestor de Temas de Escritorio (Emerald): Con el que podremos tunear nuestro escritorio y personalizarlo , apartir de los temas del repositorio de compiz: http://www.compiz-themes.org.

Estas dos utilidades se instalan desde la línea de comandos tecleando:

sudo apt-get install compizconfig-settings-manager emerald

Y se os instalarán en Sistema > Preferencias. Si quereis más referencia a cerca de compiz-fusion, o aprender simplemente como se utiliza, acceder a la wiki de compiz-fusion: http://wiki.compiz-fusion.org/

The target for this post is to embed at our MediaWiki an editor as Wordpress wysiwyg editor. For editing visual and no-problem with the back language. With Wiki applications this language is not HTML, because of the complexity or the reference systems used. They use a tagged language, Wikitext, which we could do not need or do not our users learn. In my opinion the FCKEditor is the best choice. We based on the following guide: FCKEditor Integration Guide. Download the package: mediawiki_fckeditor_ext_N.tar.gz. Unzip it and copy to the extensions directory of your MediaWiki Installation folder:

tar -zxvf mediawiki_fckeditor_ext_N.tar.gz
cp -r extensions/* /var/www/wiki/extensions/
chown -R www-data:www-data /var/www/wiki/extensions/

Finally notify to MediaWiki for loading this extension at the begining, at file LocalSettings.php:

# EXTENSIONES: Aquí incluimos las extensiones incrustadas en MediaWiki:
require_once $IP . "/extensions/FCKeditor/FCKeditor.php";

Then our edito is embebed. Refresh the cache in your browser to ensure that there is nothing cached. If you want to change the language of the interface editor, I could change modifying the following lines in the cofiguration file (fckeditor_config.js):

FCKConfig.AutoDetectLanguage    = false ;
FCKConfig.DefaultLanguage       = 'es' ;

Then we can enjoy our wiki with an easy editor.
