Pretender la libertad delante de la pantalla de un ordenador no parece tan extraño cuando pasas la mayor parte del día pegado a él
< Manual de introducción al Software Libre en 8 pasos >
1 > Concepto de software.
- Secuencia de instrucciones o indicaciones destinadas a ser utilizadas en un sistema informático para realizar una función o tarea o para obtener un resultado determinado, cualquiera que fuere su forma de expresión y fijación. Lo que normalmente llamamos programas de ordenador.
2 > Tipos de software:
- Software propietario: la copia y distribución es un delito.
- Shareware: tras un periodo de prueba es necesario pagar.
- Freeware: permiten la copia y distribución.
- Software libre: permiten la copia, distribución, modificación y posterior redistribución del software modificado.
3 > Richard Stallman – Precursor del software libre.
- Durante la época que trabaja como programador en el M.I.T. (Instituto de Tecnología de Massachusetts), el software se comparte, los programadores son una comunidad.
- En los 80 la mayoría de los programadores están ya contratados por empresas, debiendo firmar un “Nondisclosure agreement”, acuerdo de no revelar datos sobre el software que están desarrollando, y mucho menos compartirlo.
- Esto provocó que las empresas se hicieran propietarias legales del software y que la comunidad que lo compartía desapareciera.
- Richard Stallman buscó la manera de hacer posible otra vez una comunidad. ¿Como? Programando software no propietario, que se pudiera compartir.
- Su primer paso: se propuso crear un sistema operativo libre (ya que el sistema operativo es el primer programa que necesita el ordenador para funcionar). Llamó a esta idea Proyecto GNU
4 > Proyecto / Software GNU – Desarrollo de software libre.
- GNU: Acrónimo recursivo para “Gnu’s Not Unix” (Software basado en el sistema informático Unix, pero no propietario).
- Soft desarrollado por una comunidad, sin ánimo de lucro. Estás invitad@ a participar en la lista de tareas GNU (Software necesario, aún por desarrollar).
- No se debe pagar por el permiso de usarlo.
- Distribuye el código fuente (el programa escrito, sin compilar) para que, el que sepa, pueda modificar el programa según sus necesidades.
- El software propietario sólo se distribuye en binarios, listo para usar en el ordenador. Mientras que WIN y MAC mantienen el código fuente de sus sistemas operativos en secreto (sino serían también libres), GNU/Linux lo hace público.
- GNU/Linux: En 1991 Linus Torvalds programa un núcleo compatible con Unix; la combinación con soft GNU crea en 1992 el primer sistema operativo libre completo.
5 > Free Software Foundation (FSF) – Fundación para el Software Libre (FSL).
- Creada en 1985, la FSF es una organización de caridad libre de impuestos para el desarrollo de software libre.
- Acepta donaciones, pero sus ingresos provienen de la distribución de soft libre.
- El soft libre puede ser gratis o no serlo. Puedes descargarlo desde internet o puedes pedir que te envíen el software y manuales a casa.
- En 1998, parte de la comunidad deja de usar el término “free software” (software libre) por “open source software” (software de código abierto). El objetivo es evitar la confusión del término “free” (en inglés significa tanto “libre” como “gratis”). El problema viene cuando algunas empresas utilizan “open source” para que sus programas resulten atractivos o comerciales.
6 > Copyleft – Revertir el copyright.
- El software propietario tiene una licencia según la cual no eres propietario del programa, sólo puedes usarlo en un ordenador (o los que permita la licencia) y no puedes distribuirlo ni modificarlo.
- El software libre no es software de dominio público (sin copyright) para evitar versiones modificadas propietarias (que alguien le ponga copyright y lo convierta en software no libre).
- El copyleft es un método para impedir estas versiones modificadas propietarias.
- Con el software protegido con copyleft tienes permiso para usarlo, copiarlo, modificarlo y redistribuir versiones modificadas, pero NO se pueden agregar restricciones propias. Cada copia del software, aun si ha sido modificado, debe ser software libre.
- Si reservo los derechos sobre mi obra, soy su propietario, con poderes para decir que con ella puedes hacer lo que te plazca. Menos prohibir que otro haga lo mismo.
- Dos ejemplos, sacándolos del contexto del software: Wu-Ming Foundation. Aplican copyleft a sus libros, que se pueden fotocopiar y descargar de internet siempre que sean reproducciones sin ánimo de lucro (que no las vendas). Licencia arte libre (LAL). Se usa para aplicar copyleft a una obra de producción artística, ofreciendo un marco jurídico interesante para impedir cualquier apropiación abusiva.
- Los términos de distribución que usa el proyecto GNU, están contenidos en la licencia GPL (General Public License). Desarrollada por la FSF, es un contrato típico de adhesión por el que se transfieren los derechos de propiedad intelectual. El autor del software lo pone a disposición del público, que se obliga a cumplir las condiciones de la GPL desde que se distribuye el programa.
7 > Para saber si un determinado software es libre (recomendaciones de la FSF):
1 – ¿Le dan las fuentes del programa?
2 – ¿Puede modificar esas fuentes?
3 – ¿Puede distribuir lo que modifique?
4 – ¿Puede vender esas modificaciones al precio que quiera?
5 – ¿Debe añadir las fuentes obligatoriamente al distribuir?
Si la respuesta a las preguntas 1,2,3,4 es sí, es software libre. Si, además, la pregunta 5 es afirmativa, es software libre y con copyleft.
8 > Iniciativas y comunidades.

Concebida como una herramienta de iniciación al Software Libre, su utilidad, su definición e historia, la comunidad que lo mantiene y los aspectos legales en los que deriva, gnuino.org es una web para comprender conceptos básicos, permitiendo desarrollarlos mediante enlaces destacados.
Pretender la libertad delante de la pantalla de un ordenador no parece tan extraño cuando pasas la mayor parte del día pegado a él. Si tu trabajo e inquietudes necesitan la máquina, el resto es una sencilla suma de horas. Si ademas notas que tu producción se enmarca dentro de los límites de determinadas herramientas que utilizas (o puedes o te dejan utilizar), quizá quieras expandir esos límites utilizando otras herramientas que te permitan, si no es realizar otras funciones, sí tratar los problemas desde otro punto de vista.
