Cultura de usuarios M$ Windows

Usanza general del software (sistema operativo o aplicaciones) del mundo no-FOSS Free-Open Source Software):
  1. Obtener instalador (comprar CD o DVD pirata, prestarlo o descargarlo de "sitios poco recomendables")
  2. Ejecutar instalador
  3. Ejecutar generador de llave o crack del programa o sistema operativo (si no viene ya listo o hecho por crackers)
  4. Vivir con los problemas originales y los de los creadores del keygen o crack específico
  5. Asegurar que los productos M$ son los mejores.
Y eso hacen muchos que dicen que jamás "entrarían a un burdel, han visto pornografía, robarían un peso, buscarían menores de edad para fines de entrepierna o pagarían una coima o robarían en una (su) empresa".
Y pagan sus impuestos... honradamente, dicen.
Yo me cuento entre los que afirman las primeros dos posibilidades. Y tampoco pago impuestos.

Experimento con Ubuntu

Fuente Mayo 23, 2008 by Deidad

Hoy se cumplen 10 meses del experimento y desde mi punto de vista, ha resultado todo un exito, ya que sin lugar a dudas llegara al año sin ningun problema.
Les contare rapidamente de que se trata y despues unos pocos detalles de como se fue desarrollando la historia.
Hace 10 meses convenci a una persona a que aceptara que le instalara en su laptop la (en aquel entonces) ultima version de Ubuntu, despues de que esta persona me solicitara ayuda para que le instalara algunos programas que necesitaba.

History of free software

Main article: History of free software
Richard Stallman (2007)
Richard Stallman at DTU in Denmark 31 March 2007

In the 1950s, 1960s, and 1970s, it was normal for computer users to have the freedoms that are provided by free software.
Software
was commonly shared by individuals who used computers and by hardware manufacturers who were glad that people were making software that made their hardware useful. In the 1970s and early 1980s, the software industry began using technical measures (such as only distributing binary copies of computer programs) to prevent computer users from being able to study and modify software. In 1980 copyright law was extended to computer programs.

In 1983, Richard Stallman, longtime member of the hacker community at the MIT Artificial Intelligence Laboratory, announced the GNU project, saying that he had become frustrated with the effects of the change in culture of the computer industry and its users. Software development for the GNU operating system began in January 1984, and the Free Software Foundation (FSF) was founded in October 1985. He developed a free software definition and the concept of "copyleft", designed to ensure software freedom for all.

Free software is a widespread international concept, producing software used by individuals, large organizations, and governmental administrations. Free software has a very high market penetration in server-side Internet applications such as the Apache web server, MySQL database, and PHP scripting language. Completely free computing environments are available as large packages of basic system software, such as the many GNU/Linux distributions and FreeBSD. Free software developers have also created free versions of almost all commonly used desktop applications, including Web browsers, office productivity suites, and multimedia players. It is important to note, however, that in many categories, free software for individual workstations or home users has only a fraction of the market share of its proprietary competitors. Most free software is distributed online without charge, or off-line at the marginal cost of distribution, but this pricing model is not required, and people may sell copies of free software programs for any price.

The economic viability of free software has been recognised by large corporations such as IBM, Red Hat, and Sun Microsystems. Many companies whose core business is not in the IT sector choose free software for their Internet information and sales sites, due to the lower initial capital investment and ability to freely customize the application packages. Also, some non-software industries are beginning to use techniques similar to those used in free software development for their research and development process; scientists, for example, are looking towards more open development processes, and hardware such as microchips are beginning to be developed with specifications released under copyleft licenses (see the OpenCores project, for instance). Creative Commons and the free culture movement have also been largely influenced by the free software movement.

Free Software (DEF)

The first formal definition of free software was published by FSF in February 1986.
That definition, written by Richard Stallman, is still maintained today
and states that software is free software if people who receive a copy
of the software have the following four freedoms:

Freedoms 1 and 3 require source code to be available because studying and modifying software without its source code is highly impractical.
Thus, free software means that computer users
have the freedom to cooperate with whom they choose, and to control the
software they use. To summarize this into a remark distinguishing libre (freedom) software from gratis (zero price) software, Richard Stallman said: "Free software is a matter of liberty, not price. To understand the concept, you should think of 'free' as in 'free speech', not as in 'free beer'".
In the late 90s, other groups published their own definitions which
describe an almost identical set of software. The most notable are Debian Free Software Guidelines published in 1997, and the Open Source Definition, published in 1998.


The BSD-based operating systems, such as FreeBSD, OpenBSD, and NetBSD,
do not have their own formal definitions of free software. Users of
these systems generally find the same set of software to be acceptable,
but sometimes see copyleft as restrictive. They generally advocate permissive free software licenses,
which allow others to make software based on their source code, and
then release the modified result as proprietary software. Their view is
that this permissive approach is more free. The Kerberos, X.org, and Apache
software licenses are substantially similar in intent and
implementation. All of these software packages originated in academic
institutions interested in wide technology transfer (University of California, MIT, and UIUC).

Open Source Initiative

OSI logoThe Open Source Initiative is an organization dedicated to promoting open-source software.
The organization was founded in February 1998, by Bruce Perens and Eric S. Raymond, prompted by Netscape Communications Corporation publishing the source code for its flagship Netscape Communicator product.
Raymond was president from its founding until February 2005. The current president is Michael Tiemann.
Although born from the same history of Unix, Internet free software, and the hacker culture as the "Free Software" movement as defined by Richard Stallman, the formation of the Open Source Initiative, and the choice of the term "open source" was explicitly chosen to:
"...dump the moralizing and confrontational attitude that had been associated with 'free software' in the past and sell the idea strictly on the same pragmatic, business-case grounds that had motivated Netscape..."

Richard Stallman of the Free Software Foundation criticized this motivation, saying that pragmatic focus of the initiative distracts users from the central moral issues and the freedoms offered by free software, blurring the distinction with semi-free or wholly proprietary software. However, he describes the free software and the Open Source Initiative as separate political camps within the same free software community and says:

"We disagree on the basic principles, but agree more or less on the practical recommendations. So we can and do work together on many specific projects."

History
The movement was launched in 1998 by Jon "maddog" Hall, Larry Augustin, Eric S. Raymond, Bruce Perens, and others
Raymond is probably the single person most identified with the OSI and
the "open source" movement; he was and remains its self-described
principal theorist, but does not claim to lead it in any exclusive
sense. The open source movement is steered by a loose collegium of
elders that includes Raymond, its other co-founders, and such notables
as Linus Torvalds, Larry Wall, and Guido van Rossum.


The founders were dissatisfied with what they saw as the confrontational attitude of the free software
movement, and favored advocating free software exclusively on the
grounds of technical superiority (a claim previously made by Raymond in
his essay The Cathedral and the Bazaar).
It was hoped that open source and the associated propaganda would
become a more persuasive argument to businesses. Raymond's comment was "If you want to change the world, you have to co-opt the people who write the big checks." (Cygnus Support had been pursuing exactly this approach for a number of years already, but not advertising it widely.)



The group adopted the Open Source Definition for open-source software, based on the Debian Free Software Guidelines, which in turn was based on The Free Software Definition. They also established the Open Source Initiative (OSI) as a steward organization for the movement. However, they were unsuccessful in their attempt to secure a trademark
for 'open source', to act as an imprimatur and to prevent misuse of the
term. Despite this, the OSI developed considerable influence in the
corporate sphere and has been able to hold abuse of the term to a
tolerable minimum. With the Free Software Foundation (FSF), it has become one of the hacker community's two principal advocacy organizations.
The early period of the open-source movement coincided with and
partly drove the dot-com boom of 1998─2000, and saw a large growth in
the popularity of Linux
and the formation of many open-source-friendly companies. The movement
also caught the attention of the mainstream software industry, leading
to open-source software offerings by established software companies
such as Corel (Corel Linux), Sun Microsystems (OpenOffice.org), and IBM (OpenAFS).
By the time the dot-com boom busted in 2001, many of the early hopes of
open-source advocates had already borne fruit, and the movement
continued from strength to strength in the cost-cutting climate of the
2001─2003 recession.

Do It Yourself: Ringtones

Source:DSL DIY
...
(Download Dam Small Linux and start it!)
...3) Grab your favorite song in mp3 format.
(you know where to get it)
Once you have all that Launch Audacity; from your menu MyDSL -> Audacity.
After a moment or two you should have an application that looks like this:


Next open your song up in Audacity by clicking File -> Open, then selecting your choice mp3. Audacity will have to convert your mp3 into its native format. This could take a few moments. After it is done and the song is fully loaded Audacity should look something like this:


At this point you may want to play your song in Audacity to see what part of the song you want to have for your ringtone. Once you figure that part out, selecting the part of the song that you want to sample is simple. Just use your mouse to highlight the section you want.


In this screenshot I chose the beginning of the song, but you could have chosen the middle or the end just as easily.
Be sure to play the selected area so that you know that you have the right snippet for your ringtone.
Once you have the piece you like, go to Edit -> Copy to get the song snippet, then go to File -> New to launch a new Audacity window. Once the new window is open go to it and select Edit -> Paste. You now have the sampled song snippet in the new Audacity window. Half way there! Well, almost.


This screenshot is the 15 second song sample I selected. As you can see, the 15 second clip is represented in the same amount of space which causes us to have a more detailed view of the music without zooming. Notice that at the beginning of the song there is no sound, we could remove that section by selecting it with the mouse and do a Edit -> Delete. On the tail end of your music sample you may want to have the song fade out. In the photo I selected the last second and a half or so and I chose Effect -> Fade out. You can visually see the music tapering down. There are lots of effects in Audacity, but I like to keep it simple.
At this point we are dun with the editing. You should listen to the sample now and see if you like what you hear. If you do, then lets keep on going.
We are going to use Lame to do the mp3 encoding, so we will export this sample as an uncompressed .wav. In Audacity, select File -> Export as Wav. I saved mine as sample.wav.
We're all done with Audacity, now it is time to use Lame. Lame is a command line tool, so you will be using Aterm to issues the mp3 encoding commands to lame.
According to what I've read one could use 16, 24 or 32 bit rate while encoding. Most recommend not using 16 bit rate because it gives poor sound quality. On the other hand 32 bit encoding makes a much larger file. A good middle of the road approach is to use 24 bit format which makes an mp3 about 25% smaller than a 32 bit file yet still has good sound quality. On good speakers you certainly could hear the difference between 24 and 32, bot on your tiny cell phone speakers it won't make any difference.
To encode the mp3 all you have to do is: dsl@box:~$ lame -b
I chose 24 bit encoding and medium to make for a smaller file. For my wav file I gave this command:
dsl@box:~$ lame -b 24 sample.wav sample.mp3

Done! See how simple that is? Now, to get it to your phone on from DSL you have a few options:
  • Email your new ringtone to your phone
  • If your phone has USB support, plug it in and move the .mp3 over.
  • Bluetooth, well, you could save it onto a drive and access that drove from an OS that does Bluetooth later. We are only a 50MB distribution after all!

Free | Open Source Software

Why “Open Source” misses the point of Free Software
The Free Software Definition

GNU & Linux

The GNU Project was launched in 1984 to develop a complete Unix-like operating system which is free software: the GNU system.

GNU's kernel wasn't finished, so GNU is used with the kernel Linux. The combination of GNU and Linux is the GNU/Linux operating system, now used by millions. (Sometimes this combination is incorrectly called Linux.)

There are many variants or “distributions” of GNU/Linux. We recommend the GNU/Linux distributions that are 100% free software; in other words, entirely freedom-respecting.

The name “GNU” is a recursive acronym for “GNU's Not Unix”; it is pronounced g-noo, as one syllable with no vowel sound between the g and the n.

Las mujeres de Linux

Fuente

Por: Axel Marazzi

Machtelt Garrels Pia Waugh Erinn Clark
Hanna Wallach Celeste Lyn Paul Eva Brucherseifer

Si es raro ver a un hombre utilizando Linux, ver a una mujer hacerlo
es algo prácticamente imposible. No es una cuestión de discriminación,
pero parece que el sistema operativo no tiene muchas simpatizantes.



Pero para mostrarnos que SI hubo y hay muchas féminas que
contribuyeron increíblemente con el OS y con la comunidad que este
posee, la gente de LinuxHaxor decidió hacer una lista detallando qué funciones cumplen (o cumplieron) las mujeres más importantes que tiene Linux:



  • Machtelt Garrels: Es una veterana de Linux y actualmente es una consultora y entrenadora freelance. También es miembro de Linux Documentation Project, lugar que encontró para que sus escritos sean leídos en todo el mundo. Fue invitada el año pasado para que ingrese al BSD Certification Group Advisory Borrad
    y compartiera todo su conocimiento sobre la organización de
    certificaciones. El año pasado está colaborando con el grupo sin fines
    de lucro OpenDoc Society que promueve el uso de estándares libres.

  • Pia Waugh: Esta australiana está completamente dedicada al software libre. Es actualmente la presidenta de la organización Software Freedom Day y vicepresidente de Linux Australia.

  • Erinn Clark: Una desarrolladora de Debian que también fue co-fundadora y lidera actualmente el proyecto Debian Women.

  • Hanna Wallach: Desarrolladora de GNOME y Debian quien ayudó a la fundación GNOME a desarrollar el Women’s Summer Outreach Program.

  • Amaya Rodrigo Sastre: Desarrolladora de Debian y co-fundadora de Debian Women. Este es su blog.

  • Celeste Lyn Paul: Diseñadora de interacción, investigadora y contribuidora del desarrollo de open source. También lidera el KDE Usability Project, mentor de OpenUsability Season of Usability y está involucrada en el desarrollo de Kubuntu.

  • Eva Brucherseifer: Ingeniera eléctrica de Alemania que está detrás de los proyectos KDE-Women, KDE-Edu y KDE-Solaris.

  • Anne Nicolas: Directora de ingeniería de Mandriva.

  • Kristen Carlson Accardi: Desarrolladora de
    Kernel quien trabaja para Intel. Es desarrolladora de drivers desde el
    año ’90 y comenzó a concentrarse en el desarrollo de drivers para Linux
    desde el año 2005.

  • Valerie Henson: Val (así le dice todo el mundo) es una hacker del Kernel de Linux especializada en el desarrollo de filesystems. En agosto comenzará a trabajar para Red Hat. Este es su website.

  • Stormy Peters: Directora ejecutiva de la fundación GNOME. Está involucrada en la comunidad de GNOME desde el año ’99.

Gracias, Axel!!!
Una argentina para leer!
