Announcement and News
=====================

Bunch of Redundant Independent Clouds
- -------------------------------------

A software developer by the name of `Bitcartel`_ posted a long write-up
on his blog about something named `"BRIC" — "Bunch of Redundant
Independent Clouds"`_. It is a way to use consumer cloud storage
services like Dropbox, Skydrive, and Google Drive as the storage
backends in a Tahoe-LAFS grid.

It is the same general approach as Diego "sickness" Righi had posted
earlier, which was covered in `issue 31 of the Tahoe-LAFS Weekly News`_.
Bitcartel's "BRIC" comes with at least one added feature compared to
Diego's: it comes with a patch to Tahoe-LAFS to limit how much space
each storage server will use.

David-Sarah |davidsarah| mentioned in comments on Bitcartel's blog that
the patch walks over all the files each repeatedly in order to
determined how much space it is using. The "leasedb" feature that
David-Sarah is working on at LeastAuthority.com |LAE| will make it so
the storage server can efficiently know the total space usage without
having to walk over all the files.

Zooko |zooko| added BRIC to the `Tips and Tricks`_ page of the wiki.

Tahoe-LAFS on OpenWRT
- ---------------------

Stephen Walker created patches to allow to be installed on `OpenWRT`_.

"OpenWrt is described as a Linux distribution for embedded devices.

Instead of trying to create a single, static firmware, OpenWrt provides
a fully writable filesystem with package management. This frees you from
the application selection and configuration provided by the vendor and
allows you to customize the device through the use of packages to suit
any application. For developer, OpenWrt is the framework to build an
application without having to build a complete firmware around it; for
users this means the ability for full customization, to use the device
in ways never envisioned." [`0`_]

These patches will enable Tahoe-LAFS to run a large variety of embedded
devices.  Tahoe-LAFS is looking for a patch/package maintainer for
OpenWRT and a volunteer to run an OpenWRT buildslave.  If you are
interested in either of these opportunities, please let us know.  Once
we have a maintainer, we will add OpenWRT ipkg to the `current
packages`_.
