-O comando é o seguinte:+<code bash>gem install --user-install packet_name</code>
  
-<code bash>gem install --user-install nome_paquete</code> +Before the first time you must install ''ruby1.9.1-dev'':

 <code bash>aptdcon -i ruby1.9.1-dev</code> <code bash>aptdcon -i ruby1.9.1-dev</code>
  
-Ó instalar primeira xema recibirás un warning porque debes engadir un directorio ó PATH. Esto só debes facelo a primeira vezPor exemplo:+When installing the first gem a warning to add a directory to the PATH will be issuedThis must only be done the first timeFor example:
  
 <code>WARNING:  You don't have /home/remoto/jorge.suarez/.gem/ruby/1.9.1/bin in your PATH, <code>WARNING:  You don't have /home/remoto/jorge.suarez/.gem/ruby/1.9.1/bin in your PATH,
    gem executables will not run.</code>    gem executables will not run.</code>
  
-Só tes que poñelo no teu arquivo ''bashrc'' con este comando:+Add the necessary export command in your ''bashrc'' file with this command:
  
 <code bash>echo "export PATH=~/.gem/ruby/1.9.1/bin:$PATH" >> ~/.bashrc</code> <code bash>echo "export PATH=~/.gem/ruby/1.9.1/bin:$PATH" >> ~/.bashrc</code>
  
-Para que teña efecto na sesión actual, executa o comando entre comiñas, ou executa ''bash'' para entrar nunha nova shell, ou volver a entrar na sesión.+This change won't have any effect until you open a new session unless you execute the quoted part of the previous command or the ''bash'' command in the current session.

-A opción recomendada é instalar a distribución [[https://www.continuum.io/downloads#_unix|Anaconda]]. Esta distribución instálase nun directorio do usuario e permite ter varias instalacións con diferentes paquetes e distintas versións de cada paqueteNo subdirectorio ''bin'' podes atopar todos os executables típicos de pythonasí coma o xestor de paquetes ''conda'', que é máis robusto e sinxelo de usar ca ''pip''.+The recommended option is to install the [[https://www.continuum.io/downloads#_unix|Anaconda]] distributionThe advantage of this distribution is that it works from an user directory and lets the user have different installations with different versions of each packetIn the ''bin'' subdirectory you can find all the typical python executables, as well as the ''conda'' package manager which is simpler and more robust than ''pip''.
  
-Se non desexas utilizar Anaconda, podes instalar paquetes no home co seguinte comando:+If you prefer not to use Anaconda, you can still install packets with:
  
-<code bash>pip install --install-option="--user" nome_paquete</code>+<code bash>pip install --install-option="--user" packet_name</code>
  
-Antes de facelo por vez primeira, precisas instalar ''python-dev'':+Before doing it for the first time you need to install ''python-dev'':
  
 <code bash>aptdcon -i python-dev</code> <code bash>aptdcon -i python-dev</code>

-Antes de nada, crea un directorio no teu home chamado ''R'':+Firstly create a directory called ''R'' in your home:
  
 <code bash>mkdir ~/R</code> <code bash>mkdir ~/R</code>
  
-Lanza R, e dentro executa o comando de instalación de paquetes:+Run and inside it use the packet installation command:
  
 <code R>R <code R>R
-install.packages("nome_paquete")</code>+install.packages("packet_name")</code>
  
-Ó facelo preguntarache se queres facelo en ''~/R'' ó non poder escribir en ''/usr/local/lib/R''Contesta ''y''O directorio engadirase ó path de bibliotecas e poderás cargalas con normalidade.+You will be asked if you want to do it in ''~/R'' because ''/usr/local/lib/R'' cant be written intoAnswer ''y''The directory will be added to the library path and you will be able to load them.
  
-==== Al desbloquear la pantalla después de suspender, solicita dos veces la contraseña ====+==== When unblocking the screen after being idle it asks twice for the password ====

-==== Ó iniciar sesión o teclado cambia a inglés automaticamente ==== +
- +
-Esto é culpa de ''ibus''. Podes desactivar ibus se non vas a usalo (se non sabes o que é, non o estás a usar). Para facelo, vai a //Preferencias// » //Soporte de idiomas// e no desplegable de método de entrada elixe //Ningún//+
- +
-Se precisas ''ibus'', podes solucionar este problema editando a configuración de ibus [[http://askubuntu.com/questions/459617/keyboard-layout-isnt-kept-upon-reboot|como explica aquí]]. +

-==== A firma de actas da USC non funciona ==== +

-Para que a firma de actas da USC funcione, debes utilizar Firefox, e ter instalado e funcionando Java 8 de Oracle:+
  
-<code>aptdcon -i oracle-java8-installer</code>+==== After logging in the keyboard gets set to english automatically ====
  
-En Firefox, vai a //Ferramentas// » //Complementos//, e na sección Plugins, comproba que teñas activado o //Java(TM) Plug-in 11.72.2// ou superior e que teñas desactivado calquera outro complemento de java, incluíndo o //Icedtea//.+This is ''ibus'' fault. You can deactivate it if you don't plan on using it (if you don't know what ''ibus'' is then you're not using it). Go to //System settings// » //Language support// and as the keyboard input method choose //None//.
  
-Abre o //Oracle Java 8 Plugin Control panel// executando o comando <code>ControlPanel</code> na terminal e realiza os seguintes pasos:+If you need to use ''ibus'' then you can fix this problem by editing its configuration [[http://askubuntu.com/questions/459617/keyboard-layout-isnt-kept-upon-reboot|as explained here]].
  
-  - Borra os arquivos temporais, na primeira pestaña, botón //Preferencias// e logo no novo diálogo, //Borrar arquivos...//. 
-  - Engade os seguintes sitios á lista de excepcións na pestaña de //Seguridade//: 
-    * <nowiki>https://aplicacions.usc.es/</nowiki> 
-    * <nowiki>https://sec-virtual.usc.es/</nowiki> 
-    * <nowiki>https://*.usc.es/</nowiki> 
  
  
-Despois destes pasos, accede á firma de actas. O applet de proba non funciona, pero o applet de firma real si debería funcionar correctamente.
