# Goals of February 2014
- I haven't worked on this as much I would have liked, but it's one of
the most important news of the previous month for me:
David's PTTBB patches _and_ Kevin's FTE patches got merged in
tor-browser-bundle.git! This means that we now have gitian builds
for TBB that supports pluggable transports. Good news!
- Also, ScrambleSuit was merged in obfsproxy! We did an announcement
in tor-relays  and a few bridge operators have setup scramblesuit
FWIW, a few days ago, Yawning found a few bugs (#11100, #11092) in
the scramblesuit codebase that we will fix soon and roll a new
release of obfsproxy.
- As part of the new obfsproxy release and announcement we got several
mails of confused people asking reasonable questions. We hopefully
addressed most of them and made tickets for the issues that we
should fix (#11043).
- Somehow I got involved with the improved guard parameters project
that has been floating around for a while . We had several
discussions about it in the dev meeting and we made a few plans on
how to move this forward .
On this note, I started evaluating the effects that such a change
would have to the Tor network (both from the anonymity and
performance PoV) . So far that thread has generated a few useful
graphs that we need to analyze and tie together to answer a few
* How much will that change influence the performance of the
* How much will that change influence the diversity of the guard
node selection procedure?
* If we do this change, what should be the new parameters so that we
maximize the performance of the network without harming its
Nick is planning on writing a little-t-tor proposal for these design
changes. I plan to help him with that.
- mikeperry informed us of a bug in Tor that made it hard for
tor-launcher to understand whether Tor (configured with bridges)
failed to bootstrap because of network issues or because it's still
We evaluated the source of the problem (i hope) and provided some
patches to fix it (i hope). Said patches will be merged within the
0.2.5.x merge window (i hope), so that's good news for TBB.
# Goals for March 2014
- Fix #11100 and #11092 and do a new obfsproxy release.
- Include scramblesuit and FTE in TBB and get them deployed to real
- Look closer at meek: David's shiny new transport . See what needs
to happen before deployment. Start planning for deployment.
- Work on the guard stuff. Finish the analysis, decide something
useful about the parameters we should use, help Nick with the
proposal and start working on it.
- Reopen rend-spec-ng.txt and specify how HSes are supposed to pick
IPs and how long they should keep them for. Also specify how clients
are supposed to pick RPs.
- Look more at obfsclient. Look at the UniformDH spec issues that
Yawning has pointed out (#10782).
- Hope for some good GSoC students :)
