* `#42`_: Python HKDF
* `#46`_ and `#47`_: AESb
XSalsa20
* `#65`_: Microsoft compiler problems
* `#70`_: passing IVs smaller than 16 bytes to pycryptopp.cipher.aes.AES uses
          uninitialized memory

Tahoe as a Backend Driver for iRODS
- -----------------------------------

Jimmy Tang submitted the idea of `using tahoe as a backend driver for
iRODS`_.  iRODS_ is a data grid software system developed by the Data
Intensive Cyber Environments research group (developers of the SRB, the
Storage Resource Broker), and collaborators.  The list discussed Jimmy's
previous work with Tahoe-LAFS and `git-annex`_, paying attention particularly
to potential performance bottlenecks.  The prevailing hope is Jimmy will
attempt the project to determine if the potential bottlenecks are real.

Tahoe Provisioning Tool
- -----------------------

Jimmy Tang also submitted a patch for the `tahoe provisioning tool`_.  The
patch would update the provisioning tool to be more current with disk and
user data sizes.  Brian Warner |brian| contemplated removing the tool from
the Tahoe executable and making it a standalone program.  When Brian makes
this change, he will implement Jimmy's patch.  An example of Brian's work on
this may be seen here_.

Patch Needing Review of the Week
================================

There are five (5) tickets still needing review for 1.10:

* `#393`_: mutable: implement MDMF
* `#1265`_: New Visualizer is insufficiently labelled/documented (plus layout
  problem)
* `#1398`_: make docs/performance.rst more precise and accurate
* `#1566`_: if a stored share has a corrupt header, other shares held by that
  server for the file should still be accessible to clients
* `#1593`_: the drop-upload dircap should be in BASEDIR/private/
