ANNOUNCING Tahoe, the Least-Authority File System, v1.9.1

Written for Tahoe-LAFS by Zooko Wilcox-O'Hearn on 2012-01-13

ANNOUNCING Tahoe, the Least-Authority File System, v1.9.1

The Tahoe-LAFS team has announced the immediate availability of
version 1.9.1 of Tahoe-LAFS, an extremely reliable distributed
storage system. Get it here:

https://tahoe-lafs.org/source/tahoe-lafs/trunk/docs/quickstart.rst

Tahoe-LAFS is the first distributed storage system to offer
"provider-independent security" ā€” 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:

https://tahoe-lafs.org/source/tahoe-lafs/trunk/docs/about.rst

The previous stable release of Tahoe-LAFS was v1.9.0, released
on October 31, 2011.

v1.9.1 is a critical bugfix release which fixes a significant
security issue [#1654]. See the NEWS file [1] and known_issues.rst
[2] file for details.

WHAT IS IT GOOD FOR?

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.rst file [2].)

COMPATIBILITY

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

SPONSORSHIP

Atlas Networks has contributed several hosted servers for
performance testing. Thank you to Atlas Networks [11] for
their generous and public-spirited support.

And a special thanks to Least Authority Enterprises [12],
which employs several Tahoe-LAFS developers, for their
continued support.

HACK TAHOE-LAFS!

If you can find a security flaw in Tahoe-LAFS which is serious
enough that we 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" [13].

ACKNOWLEDGEMENTS

This is the tenth 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
possible.

txAWS 0.2 Released!

Written for txAWS by Thomas Herve on 2011-06-14

After 18 months of awkward silence, here is the latest release of txAWS, with among other changes improved S3 support, Python 2.7 compatibility, and the new txaws.server package.

Enjoy!

MV3D Goes Beta!

Written for MV3D by SirGolan on 2011-02-21

Iā€™m pleased to announce the 0.50 release of MV3D! With this new release, we are considering MV3D to be beta, which means future releases should not break backwards compatibility with existing data or API calls. The framework gains several major features this release such as a path-finding system for AI controlled characters and support for the Panda3D rendering engine.

Besides new features, an incredible amount of bugs have been fixed. Many of these include performance and tool chain fixes which together make this the most stable release of MV3D to date. To add to the polish, in 0.50, a user manual was added as a reference to new users.

MV3D is an open source virtual world simulation framework written in Python which uses Python-Ogre or Panda3D for graphics. It was designed with scalability in mind and aims to be able to distribute a world across as many servers as needed with dynamic load balancing.

For more information on MV3D and this or future releases, please visit the website at http://www.mv3d.com. The full release notes for version 0.5 are available at this url: http://www.mv3d.com/trac/browser/tags/mv3d-0.50/release-notes.txt
For further inquiries, email mike at mv3d dot com, or stop by the IRC chat room, #MV3D on irc.freenode.net.

Thanks,
Mike
