Dibujar un eje de coordenadas en LaTeX usando pstricks.

   Muchas veces al realizar un documento científico resulta útil dibujar una función. Para ello conviene empezar por conocer cómo se pinta un eje de coordenadas.

   Una opción sencilla para pintar tanto ejes de coordenadas como funciones, diagramas, grafos, ... es utilizando pstricks. 
   Para emplear pstricks es conveniente añadir los siguientes paquetes al documento:

\usepackage{pstricks}
\usepackage{pst-node}
\usepackage{pst-plot}

  A partir de ahora ya se puede empezar a insertar gráficos usando pstricks. La forma más sencilla de dibujar un eje es mediante la sentencia \psaxes. Un ejemplo muy sencillo es el siguiente:

\begin{pspicture}(0,0)(4,3)
 \psaxes{->}(4,3)
\end{pspicture}

La forma de la macro es la siguiente:

\psaxes*[par]{arrows}(x0,y0)(x1,y1)(x2,y2)

Las coordenadas son cartesianas. Los puntos (x1,y1)(x2,y2) son la esquina inferior y la esquina superior respectivamente. El punto (x0,y0) indica donde se intersecta el eje x con el eje y.

\psaxes[linewidth=1.2pt,labels=none, ticks=none]{<->}(2,1)(0,0)(4,3)

Si se omite el punto (x0,y0) entonces el origen es el punto (x1,y1). Si se omiten (x0,y0) y (x1,y1) entonces el punto de corte es el (0,0).


Los parámetros que pueden ir dentro del corchete son los siguientes:

• labels=all/x/y/none   Por defecto: all
     Especifica si las etiquetas de los ejes aparecen en ambos ejes, sólo en el eje x, sólo en el eje y o ninguna etiqueta respectivamente.
  
• showorigin=true/false  Por defecto: true
     Si true, las etiquetas se ponen las etiquetas del origen. Si es falso no se ponen etiquetas en el origen.
  
• fdsfsa

Bueno, navegando un poco he encontrado una lista de colores para usar en LaTeX que está muy completa.

Error: El sonido no funciona en karmic koala tras la actualización.

El sonido no funciona en karmic koala tras la actualización.
No tengo muchas ganas de explicar lo que hace cada sentencia, así que directamente pondré los comandos que hay que meter en la consola uno tras otro:

sudo apt-get install grub2 linux-backports-modules-alsa-karmic-generic

sudo add-apt-repository ppa:ubuntu-audio-dev/ppa

sudo apt-get update

sudo apt-get dist-upgrade

mkdir ~/pulse-backup && cp -r ~/.pulse ~/.asound* /etc/asound.conf

(Sigue la línea) /etc/pulse -t ~/pulse-backup/
 

rm -r ~/.pulse ~/.asound* 
 

sudo rm /etc/asound.conf 

sudo apt-get install libasound2-plugins padevchooser 

(Sigue la línea) libsdl1.2debian-pulseaudio

sudo apt-get remove --purge libflashsupport 

(Sigue la línea)flashplugin-nonfree-extrasound

pulseaudio & pavucontrol 

Si quieres echarle un vistazo al volumen:

alsamixer -Dhw

Eso es todo. Ánimo!!

Error en la actualización de Kubuntu Jaunty Jackalope a Karmic Koala

Buenas!!

Si has tratado de actualizar el sistema operativo de tu Kubuntu Jaunty Jackalope a un Kubuntu Karmic Koala y te has encontrado con que al reiniciar dice algo sobre un error al montar el sistema de ficheros, no está todo perdido.

Dice algo así:

General error mounting filesystems a maintenance will now be started.

Pulsa Control + D para acceder como root y pon tu superclave.

Una vez como root tendrás que remontar el sistema de ficheros pues estará como read-only.

mount -o remount /dev/sdaX

donde X es el número de la partición.

NOTA: Sólo si no sabes cuál es tu X: Si no lo tienes claro utiliza el comando
fsck -f
En la fila donde ponga +Linux será la que indica el sdaX que debes usar. En mi caso solo tengo instalado linux por lo que es sda1.

Sigamos, probablemente tendrás dañado el apt-get de tu linux y habrá que arreglarlo.

dpkg --configure -a

Este paso funcionará si has remontado tu disco, en el que se encuentra el sistema de ficheros de linux, correctamente.

Lo siguiente es reparar la actualización y sus errores. Para ello:

apt-get -f install

Por último, un

apt-get dist-upgrade


y ahora ya solo falta reiniciar.

shutdown -r now

Cómo compilar una aplicación Java que conecta con una base de datos.

Si tenemos un código parecido a este:

import java.sql.*;

public class MysqlConnect {
public static void main(String[] args) {
System.out.println("MySQL Connect Example.");
Connection conn = null;
String url = "jdbc:mysql://localhost:3306/";
String dbName = "nombre_de_la_base_de_datos";
String userName = "usuario";
String password = "micontraseña";
try {
Class.forName("com.mysql.jdbc.Driver").newInstance();
conn = DriverManager.getConnection(url + dbName,userName,password);
System.out.println("Connected to the database");
conn.close();
System.out.println("Disconnected from database");
} catch (Exception e) {
e.printStackTrace();
}
}
}

Podemos compilar de la siguiente manera:

gcj -O2 mysql-connector-java-3.0.17-ga-bin.jar MysqlConnect.java --main=MysqlConnect -findirect-dispatch

Para poder hacer esto, hay que bajarse el paquete mysql-connector-java-3.0.17-ga-bin.jar y poner en la misma carpeta que el fichero fuente MysqlConnect.java

Instalar los drivers de HP en Linux Kubuntu

Bueno, en kde 4 kubuntu jaunty jackalope, por alguna razón que desconozco la hp 845c no imprime correctamente. Lo que hace es expulsar un folio en blanco. Una solución es instalar los drivers de Hp. Viene todo muy bien explicado en la siguiente dirección:

http://hplipopensource.com/hplip-web/install/manual/distros/ubuntu.html

Actualizar la versión de KDE de Jaunty Jackalope a Kde 4.3

sudo sh -c "echo 'deb http://ppa.launchpad.net/kubuntu-ppa/backports/ubuntu jaunty main' >> /etc/apt/sources.list"
sudo sh -c "echo 'deb http://ppa.launchpad.net/kubuntu-ppa/staging/ubuntu jaunty main' >> /etc/apt/sources.list"



sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 8AC93F7A



sudo aptitude update && sudo aptitude dist-upgrade

Una buena página que lo explica con detalle es:

Java: Tamaños de letra grande en las aplicaciones (GUI) por culpa del intérprete que viene en el repositorio de Kubuntu Jaunty

Bueno, para evitar que las fuentes de los controles se vean tan grades lo mejor es actualizar la JVM

Para ello la descargamos de la página oficial:

Descargar de sun.com

Y ahora en la consola y en el directorio en el que se ha descargado:

cd

Normalmente es Escritorio.

chmod +x jre-6-linux-i586.bin

sudo ./jre-6-linux-i586.bin

sudo mv jre1.6.0_14 /usr/lib/jvm/

sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jre1.6.0_14/bin/java" 1

sudo update-alternatives --set java /usr/lib/jvm/jre1.6.0_14/bin/java

java -version

Y este es el resultado:

java version "1.6.0_06"
Java(TM) SE Runtime Environment (build 1.6.0_06-b02)
Java HotSpot(TM) Client VM (build 10.0-b22, mixed mode, sharing)
