Eclipse in ubuntu

Eclipse is a multi-language Integrated development environment (IDE) comprising a base workspace and an extensible plug-in system for customizing the environment. It is written mostly in Java. It can be used to develop applications in Java and, by means of various plug-ins, other programming languages including Ada, C, C++, COBOL, Fortran, Haskell, JavaScript, Perl, PHP, Python, R, Ruby (including Ruby on Rails framework), Scala, Clojure, Groovy, Scheme, and Erlang. It can also be used to develop packages for the software Mathematica. Development environments include the Eclipse Java development tools (JDT) for Java and Scala, Eclipse CDT for C/C++ and Eclipse PDT for PHP, among others.

The initial codebase originated from IBM VisualAge.[2] The Eclipse software development kit (SDK), which includes the Java development tools, is meant for Java developers. Users can extend its abilities by installing plug-ins written for the Eclipse Platform, such as development toolkits for other programming languages, and can write and contribute their own plug-in modules.

Released under the terms of the Eclipse Public License, Eclipse SDK is free and open source software (although it is incompatible with the GNU General Public License[3]). It was one of the first IDEs to run under GNU Classpath and it runs without problems under IcedTea.

Ubuntu, here are some steps that help you getting Eclipse working on Ubuntu

1. Install Sun Java JDK

#sudo apt-get install sun-java6-jdk

2.  Download Eclipse
You can go to official site http://www.eclipse.org/downloads/ and choose your edition,

Save to your Desktop

3. Extract Eclipse
Open Terminal, and execute:

#cd ~/Desktop
#tar xzf eclipse-php-galileo-linux-gtk.tar.gz (replace your downloaded file name here)
#sudo mv eclipse /opt/eclipse
#sudo mv eclipse-galileo.png /opt/eclipse
#cd /opt
#sudo chown -R root:root eclipse
#sudo chmod -R 755 eclipse
#cd /opt/eclipse
#sudo chmod +x eclipse

4. Create a .desktop file to eclipse:

gedit ~/.local/share/applications/opt_eclipse.desktop

Then, paste this inside (dont forget to edit Exec and Icon values):

[Desktop Entry]
Type=Application
Name=Eclipse
Comment=Eclipse Integrated Development Environment
Icon=** something like /opt/eclipse/icon.xpm **
Exec= ** something like /opt/eclipse/eclipse **
Terminal=false
Categories=Development;IDE;Java;
StartupWMClass=Eclipse

After that, open that folder with nautilus:

nautilus ~/.local/share/applications

If you want to use this launcher outside dash/launcher (ex: as a desktop launcher) you need to add execution permission by right clicking the file and choosing Properties -> Permissions -> Allow execution, or, via the command-line:

chmod +x ~/.local/share/applications/opt_eclipse.desktop

Finally drop opt_eclipse.desktop to launcher.

Optimización de sitios de Internet

Para hablar de optimización es necesario primero definir el criterio de optimalidad.  En el caso de sitios de Internet el criterio es trafico y el logro de objetivos específicos.

Un aspecto primordial para la generación de trafico es la colocación del sitio es los buscadores; sin embargo, el logro de objetivos depende de la experiencia del usuario una vez que llega a la pagina: que el usuario encuentre fácilmente lo que esta buscando; que los objetivos del usuario se correlacionen con los objetivos del sitio; que la pagina se cargue dentro de los tiempos  tolerados por el usuario.

Algunos lineamientos generales en los que coinciden los expertos:

  • Mantener el diseño de paginas y del sitio en general lo más simple posible.
  • Evitar el uso de Flash e imágenes para presentar información.
  • Usar paginas estáticas en la medida de lo posible en vez de contenido dinámico.
  • Mantener la navegación del sitio lo más plano posible, con no más de tres niveles.
  • Enfocar el contenido a temas muy concretos y presentar información relevante y única.
  • Conseguir ligas de sitios importantes y relevantes con respecto a la temática del sitio.

En términos técnicos los recomendaciones implican,  por ejemplo, el uso de CSS para lograr efectos, CSS Sprites, datos embebidos.

CSS; la ortogonalidad del contenido y el diseño

Uno de los preceptos fundamentales del diseño es la separación de responsabilidades entre módulos o componentes. Idealmente cada modulo debe tener un sola responsabilidad primaria. En particular, la funcionalidad de un componente debe ser independiente de la interfaz de usuario.

CSS es un medio de aislar el diseño grafico del contenido textual de un documento. Un ejemplo espectacular de la ortogonalidad del contenido y el diseño se puede ver en CSS Zen Garden
