ANNOUNCING Tahoe, the Least-Authority File System, v1.8.0

Discussion in 'Python' started by Zooko O'Whielacronx, Sep 30, 2010.

  1. Hello, people of python-list. This storage project uses Python for
    almost everything, except we use C/C++ for the CPU-intensive
    computations (cryptography and erasure coding) and we use JavaScript
    for some user interface bits. We're even looking at the possibility of
    replacing the C/C++ crypto code with pure-Python code, relying on JIT
    compilers such as PyPy to make it efficient enough. :)!/fijall/status/25314330015



    ANNOUNCING Tahoe, the Least-Authority File System, v1.8.0

    The Tahoe-LAFS team is pleased to announce the immediate
    availability of version 1.8.0 of Tahoe-LAFS, an extremely
    reliable distributed storage system. Get it here:

    Tahoe-LAFS is the first distributed storage system to offer
    "provider-independent security" — meaning that not even the
    operators of your storage servers can read or alter your data
    without your consent. Here is the one-page explanation of its
    unique security and fault-tolerance properties:

    The previous stable release of Tahoe-LAFS was v1.7.1, which was
    released July 18, 2010 [1].

    v1.8.0 offers greatly improved performance and fault-tolerance
    of downloads and improved Windows support. See the NEWS file
    [2] for details.


    With Tahoe-LAFS, you distribute your filesystem across
    multiple servers, and even if some of the servers fail or are
    taken over by an attacker, the entire filesystem continues to
    work correctly, and continues to preserve your privacy and
    security. You can easily share specific files and directories
    with other people.

    In addition to the core storage system itself, volunteers
    have built other projects on top of Tahoe-LAFS and have
    integrated Tahoe-LAFS with existing systems, including
    Windows, JavaScript, iPhone, Android, Hadoop, Flume, Django,
    Puppet, bzr, mercurial, perforce, duplicity, TiddlyWiki, and
    more. See the Related Projects page on the wiki [3].

    We believe that strong cryptography, Free and Open Source
    Software, erasure coding, and principled engineering practices
    make Tahoe-LAFS safer than RAID, removable drive, tape,
    on-line backup or cloud storage.

    This software is developed under test-driven development, and
    there are no known bugs or security flaws which would
    compromise confidentiality or data integrity under recommended
    use. (For all important issues that we are currently aware of
    please see the known_issues.txt file [4].)


    This release is compatible with the version 1 series of
    Tahoe-LAFS. Clients from this release can write files and
    directories in the format used by clients of all versions back
    to v1.0 (which was released March 25, 2008). Clients from this
    release can read files and directories produced by clients of
    all versions since v1.0. Servers from this release can serve
    clients of all versions back to v1.0 and clients from this
    release can use servers of all versions back to v1.0.

    This is the eleventh release in the version 1 series. This
    series of Tahoe-LAFS will be actively supported and maintained
    for the forseeable future, and future versions of Tahoe-LAFS
    will retain the ability to read and write files compatible
    with this series.

    You may use this package under the Transitive Grace Period
    Public Licence, version 1 or, at your option, any later
    version. (The Transitive Grace Period Public Licence has
    requirements similar to the GPL except that it allows you to

    work before releasing the source code of your derived work.)

    Transitive Grace Period Public Licence, version 1.

    (You may choose to use this package under the terms of either
    licence, at your option.)


    Tahoe-LAFS works on Linux, Mac OS X, Windows, Cygwin, Solaris,
    *BSD, and probably most other systems. Start with
    "docs/quickstart.html" [7].


    Please join us on the mailing list [8]. Patches are gratefully
    accepted -- the RoadMap page [9] shows the next improvements
    that we plan to make and CREDITS [10] lists the names of people
    who've contributed to the project. The Dev page [11] contains
    resources for hackers.


    Tahoe-LAFS was originally developed by Allmydata, Inc., a
    provider of commercial backup services. After discontinuing
    funding of Tahoe-LAFS R&D in early 2009, they continued
    to provide servers, bandwidth, small personal gifts as tokens
    of appreciation, and bug reports.

    Google, Inc. sponsored Tahoe-LAFS development as part of the
    Google Summer of Code 2010. They awarded four sponsorships to
    students from around the world to hack on Tahoe-LAFS that

    Thank you to Allmydata and Google for their generous and
    public-spirited support.


    If you can find a security flaw in Tahoe-LAFS which is serious
    enough that feel compelled to warn our users and issue a fix,
    then we will award you with a customized t-shirts with your
    exploit printed on it and add you to the "Hack Tahoe-LAFS Hall
    Of Fame" [12].


    This is the fifth release of Tahoe-LAFS to be created solely
    as a labor of love by volunteers. Thank you very much to the
    team of "hackers in the public interest" who make Tahoe-LAFS
