Free Software

  • Brief History: GNU (GNU’s Not Unix) as a response to close sourcing
    • Copyright Act of 1976 – Late 1970s, software compaines stopped to distribute sources code with software.
    • Xerox Printer – When Richard Stallmans (a MIT AI lab hacker) want to change the function of the printer driver, the request was refused because the sources code is not open
    • Decline of MIT Hacker Culture – When the policy change, Richard Stallmans refused to sign non-disclosure agreements not to share source code or technical information. Because he think that software should always be free, and user should be able to change it as they need
    • Founded the GNU Project – Build a operating system which is “free”.
  • Definition:
    • GNU Manifesto
    • Free Software
      • You have the freedom to run the program, for any purpose.
      • You have the freedom to modify the program to suit your needs.
      • You have the freedom to redistribute copies, either gratis or for a fee.
      • You have the freedom to distribute modified versions of the program, so that the community can benefit from your improvements.
    • Free Speech, not Free Beer
  • What GNU do:
    • An alternative – GNU is a new computer system, alternative to Unix
    • Raise Awareness – A lot of public speaking
    • Legislation – Political campaign against software patent, copyright, etc…

    Open Sources Movement

  • Brief History: “Open Sources” as a marketing buzzword (1990s) – Free means cheap, and cheap is no good
  • “Marriage” with Free Software Movement
    • When Linus developed a Unix-competiable operating system kernel (Linux), but lacking of a system libraries; And Richard Stallman developed a Unix-competiable system libraries (GNU Project), but lacking of a system kernel. GNU / Linux
  • “Break up” with Free Software Movement
    • Alan Cox – “Majority of the kernel developers don’t buy the FSF political agenda” / Eric Raymond – “If you want to change the world, you have to co-opt the people who write the big-checks”
    • GPLv3 – Should we accept DRM hardware?
  • Why Open Sources?
    • Technical-Superiority – Open sources model lead to software
    • Persuasive to business
  • How business model integrate with open sources model?
    • Redhat, MySQL, JBoss – Sale of services or “Side-product”
    • IBM, Sun – Open sources to encourage Open Standard as a way to break the Network Effect
    • HP, Router Manufactuor – Open sources as a way to cut-cost, cheap way to produce products
    • Innovation Happens Elsewhere
  • Open Sources Development Model — Democratizations?

  • Technical Tools
    • Mailing List
    • IRC
    • Wiki
  • Characteristics
    • No Hierarchy
    • Micro contribution
    • Lengthy Discussion
    • Forking
  • Case Studies
    • Wikipedia (“Too many rules” Problem, Hierarchy and Rewards)
    • Linux (Charismatic Leader — Linus)

    Copyleft

    • Different Level of Copyleft:
    • Strong / Weak Copyleft (GPL / LGPL) – Strong Copyleft License always impose its license to all derivated work, while Weak Copyleft do not. GPL is a Strong Copyleft License since any code used “GPLed” code have to be released in GPL license too. While LGPL have an exemption of when new code is dynamically linked with “LGPLed” code, the new code do not have to be licensed under LGPL. Application of Strong Copyleft work includes Wikipedia.
    • Full / Partial Copyleft
  • Copyleft vs “BSD-style” license
    • BSD-style – Some time refer as “Permissive Free Software License”, close to public domain. Except: (some example, such as old BSD license require attribution of Berekely University)
    • Cristism: Both side claim that the other side is not as “free”.
  • Copyleft vs Public Domain
    • Public Domain – No right reserved.
    • Cristism: How about the atomcity of art work?
  • Discussion: What is “free”? GPL / BSD / Public Domain?

Related Movements

  • Anti-DRM
    • what is DRM?
      • To enforce certain copyright limitation by technology measures.
      • Leaded by major copyright holders and computer industry, concerning their own rights only, neglecting many other issues, as followed.
    • as a privacy problem
      • Trusted Computing
        • Computer industry tries to make computer or any electronic devices only trust DRM materials. By this measures, old materials that does not employ DRM cannot be used in new devices. In the implementation, usually a particular ID is given to all products, and thus people could be traced by such ID. Also, people lose their control to the devices.
      • Spyware (Sony Case)
        • Sony’s DRM on their CDs forced users to play the CD with their own softwares in computer. It was later found that the software contains spyware, which steal users’ personal information. Sony was ruled to let customers exchange new discs, give penalties to customers, never does such harm to customer again and put spyware cleaner in their website for two years.
    • as a business problem
      • Unsuccessful Business Model (Yahoo’s Executive Speech)
        • Many music and movie resaler has voice out that DRM is not a successful business model, including Steve Jobs from Apple iTune and Ian Rogers from Yahoo! Music. One basic argument is that DRM does not add value to customer. Rather than that, DRM lower the value to purchasing CD/DVD, making purchasing CD/DVD becomes even less competitive than piracy.
      • Anti-Competition
        • Current DRM systems are dominated by a few IT giant companies. They design their own DRM system, such that customer must use particular device to play or use the media. For example, the DRMed music on iTune can only be played on iPod. European Union has ruled that Apple must let the DRM technology open to other companies, so that it does not lead to anit-competition.
        • Cyberport advocate OpenDRM, which is a vendor free DRM. Is it good for customer?
    • on a moral ground
      • Lawerence Lessig: Law by Business Sector (E.g. Fairuse)
        • By the very basic principle of copyright law, it is to protect expressions of ideas, but not protecting business. Thus copyright law provides fairuse or fair dealing, which are exceptions of using copyright works so that won’t bounded reasonable usage of works or limit follow-up creations. But with DRM, these exceptions cannot be implemented, as they are not able to quantized to computer programs.
      • Ownership or Rights?
        • We used to own a product when we buy it. With DRM, we only has limited right to use the product. For example, for DRMed CD, we only has the right to play the CD, but not making backup, or converting them to MP3.
    • on a economic ground
      • derivative work right
        • DRM technology ban several usage to the materials thus usually forbid derivate work. However, Copyright do allows some derivative work right, such as Parody. In an economic point of view, copyrighted work produce value when people consume it, and also when people derivate more work from it, forbidding derivate work reduce the value.
      • cost to use it
      • In an economic point of view, DRM always add the cost to consume a creative work. Either the creator, publisher or consumer has more difficulties and cost compared with no DRM.
  • Open Document Format vs OOXML (http://www.noooxml.org/)
    • Basic ideas about closed document format and opened document format
      • closed file format
        • only the developer knows how to read/write this format (e.g. Microsoft Office)
      • opened file format
        • the format specfication is open to public, anyone may understand and implementing such format (e.g. ODF)
      • advantage of opened document format
        • the opennesss guarantees the document can be read even the developing vendor closed down (no Vendor Lock-in)
        • as anyone can implement the format, more people can involved in developing programs for that, helping the improvment of working environment
    • ODF vs OOXML
      • ODF – OpenDocument Format
        • developed by OASIS, a organization to design open file format
        • now used by OpenOffice, StarOffice, K Office etc.
        • approved by ISO on 2006
      • OOXML – Office Open XML
        • developed by Microsoft
        • submitting for ISO
      • ODF vs OOXML
        • OOXML is only developed and used by Microsoft. Actually, there is no full implementation for OOXML yet, not even the latest MS Office.
        • duplicated ISO open document format will cause confusion
        • many functions are not explained in OOXML specification, such that implementing OOXML will need MS support. There is no guarantee that implementing OOXML will not violate MS patent.
        • Microsoft admit that they pay to ISO voters, in order to let OOXML pass ISO.

        Hong Kong Case Studies: Digital copyrights consultation

          1. The criminalization of all downloading activities except from cachePushing BT case forward: uploading of seed file and its debate
        • 2. The protection of copyright works transmitted to the public via all forms of communication technology, such as the transmitting of CD to MP3
        • i.e: format shifting, Digital rights management
        • 3. Pressure to the Online Service Providers for releasing users’ information and introducing filtering technologyThe issue of piracy and censorship

          4. Statutory Damages for Copyright Infringement

          The issue of harm
