Tears of Steel | Mango Open Movie Project La cattedrale e il bazaar di Eric S. Raymond (22/11/1998 ore 04:01:20) Quella che segue è la mia analisi di un progetto open source di successo, fetchmail, deliberatamente utilizzato come test specifico per la verifica di alcune sorprendenti teorie sullo sviluppo del software suggerite dalla storia di Linux. Le mie argomentazioni su tali teorie mettono a confronto due diversi stili di sviluppo, il modello “cattedrale” in voga in gran parte del mondo commerciale, opposto al modello “bazaar” del mondo Linux. Sommario: 1. Linux è sovversivo. Certamente non il sottoscritto. Linux stravolse gran parte di quel che credevo di sapere. Rimasi non poco sorpreso dallo stile di sviluppo proprio di Linus Torvalds – diffondere le release presto e spesso, delegare ad altri tutto il possibile, essere aperti fino alla promiscuità. Il fatto che questo stile bazaar sembrasse funzionare, e anche piuttosto bene, mi colpì come uno shock. Fu verso la metà del 1996 che mi parve d'essere sul punto di capirne il perché. 2. 1. 2. 3. 4. 5.
Big Buck Bunny The Cathedral and the Bazaar This directory gives you access to almost all of the contents of my evolving book, The Cathedral and the Bazaar. Enjoy — but be aware that I have sold O'Reilly the exclusive commercial printing rights. The papers composing this book (like their topic) are still evolving as I get more feedback. I made extensive revisions and additions for the first edition of the book The Cathedral and the Bazaar, and expect to continue adding and revising in future editions. Even if you've heard me do the stand-up version, you may want to reread it. These papers are not `finished', and may never be. If you like these papers, you will probably also enjoy my How To Become A Hacker FAQ (also in the book). Here's the XHTML. My thumbnail sketch of the history of the hacker culture, maintained since about 1992. Here's the XHTML. Translations Here's the XHTML. You can download RealAudio recordings of the stand-up version of this talk from the Kongress (about the first 30 seconds is missing). Forrest J.
Definition of Free Cultural Works Definition/It - Definition of Free Cultural Works Versione stabile Questa è la versione stabile 1.1 della definizione. Il numero di versione verrà aggiornato con lo sviluppo della definizione. La versione modificabile della definizione si trova su Definition/Unstable (in inglese). Si veda authoring process per maggiori informazioni, e translations se vuoi contribuire a una versione in una lingua differente. Riassunto[edit] Questo documento definisce le "Opere Culturali Libere" ("Free Cultural Works") come opere o espressioni che possono essere liberamente studiate, utilizzate, copiate e/o modificate da chiunque, per qualsiasi scopo. Preambolo[edit] I progressi sociali e tecnologici rendono possibile a una crescente parte dell'umanità di accedere, creare, modificare, pubblicare e distribuire vari tipi di opere - opere d'arte, materiali scientifici ed educativi, software, articoli - in breve: tutto ciò che può essere rappresentato in forma digitale. Identificare le Opere Culturali Libere[edit] Definire le Free Culture Licenses[edit]
Copyleft: Pragmatic Idealism by Richard Stallman Every decision a person makes stems from the person's values and goals. People can have many different goals and values; fame, profit, love, survival, fun, and freedom, are just some of the goals that a good person might have. When the goal is a matter of principle, we call that idealism. My work on free software is motivated by an idealistic goal: spreading freedom and cooperation. I want to encourage free software to spread, replacing proprietary software that forbids cooperation, and thus make our society better. That's the basic reason why the GNU General Public License is written the way it is—as a copyleft. Not everyone who uses the GNU GPL has this goal. “Sometimes I work on free software, and sometimes I work on proprietary software—but when I work on proprietary software, I expect to get paid.” If you want to accomplish something in the world, idealism is not enough—you need to choose a method that works to achieve the goal. Consider GNU C++.
Free culture movement The movement objects to overly-restrictive copyright laws. Many members of the movement argue that such laws hinder creativity. They call this system "permission culture. Creative Commons is an organization started by Lawrence Lessig which provides licenses that permit sharing under various conditions, and also offers an online search of various Creative Commons-licensed works. The free culture movement, with its ethos of free exchange of ideas, is aligned with the free software movement. Background[edit] In 1998, the United States Congress passed the Sonny Bono Copyright Term Extension Act which President Clinton signed into law. In 1999, Lessig challenged the Bono Act, taking the case to the US Supreme Court. In 2001, Lessig initiated Creative Commons, an alternative “some rights reserved” licensing system to the default “all rights reserved” copyright system. Organizations[edit] The organization commonly associated with free culture is Creative Commons (CC), founded by Lawrence Lessig.
