I worked mainly on documentation and specification tasks related to
OONI. Did a bit of travelling and a bit of coding too.
# Documentation/Design related
The wiki is starting to look good. Most of the basic analysis required
for moving on to implementing
OONI is in place. We still need to have some more discussion on a few
design choices, but the overall
concept is in place.
In particular we have finished the analysis of Tests.
I created templates for the analysis of Censorship detection tools
did the analysis of Neubot:
and of Herdict:
We created the methodology for specifying and writing OONI probe tests:
created a module view and a component and connector view and specified
architecture of OONI:
I started defining the API for the backend system in particular the
In the past days had some discussions with jake and isis if we should be
using HTTP for reporting.
Jake suggested that we use rsync instead of HTTP. I will detail in a
following mail the pro and cotra
of one solution over the other.
We finished specifying the basic set of Test for OONI here:
The data collection scheme has been defined here:
I got a few good tips from Nick on the topic of design and specification
of software. What I took from it is that in the end the design that you
make will not be ultimate and you will end up changing it. For this
reason it's good to start implementing some of the tests and that will
allow you to understand what is the abstraction that fits all of them.
He used a very nice analogy, it's like having a set of points in N
dimensional space and by designing an abstraction for it you are trying
to find an hypercube that fits all of them (I may have a bit
Implemented an HTTP utility library for writing HTTP based OONI tests
and implemented a few of the using
Wrote a OONI scapy twisted library that replaces scapys send and receive
functions with some based on
twisted. Wrote an OONI Test protocol for it.
Implemented based on OONI a test written by phw that does packet
mutation to bissect censorship fingerprints.
Misc. code refactoring.
Travelled to Madrid to do a talk on Tor and GlobaLeaks. Met there with
Went to hackmeeting in l'Aquila and did a talk about Tor and censorship
( http://www.slideshare.net/hellais/tor-censorship-2012-ooni). I believe
this talk went very well and everybody was very excited about Tor at the
end of it.
# What I plan to do next
Work on drawing these N dots, by implementing test for OONI. I will
finish one of the first fully client server tests based on OONI called
b0wser (the server part is almost done). Figure out what should be done
with the backend and start having a test backend deployment on ooni.nu.
