• Checkstyle.- Parece bueno Checkstyle is a development tool to help programmers write Java code that adheres to a coding standard.
• Artistic Style.- Sólo indenta
• ImportScrubber.- Organizador de imports.
  Tiene limitaciones muy gordas: Ver
• Jacobe.-
• JCSC.- Muchos chequeos distintos.
• PMD.- Parece bueno. PMD scans Java source code and looks for potential problems.
• Jlint.- El autor dice que es muy rapido, y no me estraña. Está hecho en C.
  Jlint will check your Java code and find bugs, inconsistencies and synchronization problems
• Ick.- Import management tool for Java programs written in Java.
  Sencillo, pero hace su labor.

Llevo ya casi 15 días sólo.
Mi mujer y mi hijo están de vacaciones en Santander, y yo de Rodríguez.
Me iba a hacer un gazpacho, pero, al mirar en la nevera, he visto con sorpresa que la cebolla y los pepinos tienen una capa de moho de un par de centímetros.
Esto no lo había visto desde que vivía en piso compartido con los colegas (Un saludo a Toni, Berto y Kike).
Suerte que me he dado cuenta, porque el moho se estaba apoderando de la nevera.
Así que, como medida de emergencia, he cogido el teléfono y he llamado a mi mamá (que también está de vacaciones en la playa, en Mazarrón).
Le he contado mi gran problema y me ha dado ánimos y una receta de gazpacho sin cebolla y sin pepino.
Me dispongo a escribirla aquí para que no se me olvide:

Ingrediente:

• Pan duro de ayer en remojo.
• 6 tomates. Pelados para no encontrar los trocitos de pellejo.
• Un poquito de sal.
• 3/4 de un vaso tamaño "vaso de agua" lleno de aceite de oliva (Si es de un grado mejor).
• Un chorreoncillo de vinagre.
• 2 dientes de ajo.
• 2 llemas de huevos. Ojos, sólo las yemas!!!

Todo esto en la batidora y a batir!!
Se mete en el congelador para que se refresque un poco y ya tengo la cena preparada.

Vamos a imprir un documento metiendo en un hoja dos páginas del documento y vamos a imprimir estas hojas por las dos caras.
Para el ejemplo usuaremos el manual de css2.1 que tenemos en pdf.

• Paso 1.

  Pasamos a ps.
  # pdf2ps css2.1_spa.pdf css2.1_spa.ps

• Paso 2.

  Generamos dos páginas por hoja.
  # psnup -2 css2.1_spa.ps css2.1_spa_2pps.ps

• Paso 3.

  Separamos las impares de las pares y las ponemos en orden inverso.
  # psselect -o -r css2.1_spa_2pps.ps css2.1_spa_2pps_impares.ps

• Paso 4.

  Vamos imprimiendo las hojas impares.
  # lp css2.1_spa_2pps_impares.ps

• Paso 5.

  Separamos las pares de las impares.
  # psselect -e css2.1_spa_2pps.ps css2.1_spa_2pps_pares.ps

• Paso 6.

  Imprimimos las hojas pares.
  Una vez que se terminan de imprimir las hojas impares, ponemos en la fuente del papel el taco de folios con la impresión de las hojas impares.
  Imprimimos y se imprimirá por el reverso en blanco de las hojas impares.
  # lp css2.1_spa_2pps_pares.ps

Ahora vamos a coger una imagen en postcript y la vamos a generar otra en forma de poster.
Usaremos un ps con el modelo de datos de una aplicación (lógicamente, puede ser cualquier imagen).
El primer comando generará un poster de cuatro hojas (2x2) en A4, sin márgenes para las marcas que se generan para cortar.
El segundo lo envía a la impresora.
# poster -v -c0 -w0 -mA4 -s2 modeloDeDatos.ps > modeloDeDatosPoster.ps
# lp provercomModelo2.ps

Fácil, verdad? Luego dicen que linux es complicado.
Decir que esto vale para cualquier impresora, tanto para la impresora matricial que tienes tirada en el trastero como para la flamante impresora laser en color de la oficina.
