[tor-dev] Starting work on hidden services

Hi everyone,

I'm an undergraduate student at University of Campinas, in Brazil, starting
now I'll be working all year, >=20h/week on research about and improvements
to tor hidden services under the supervision of Prof. Diego F. Aranha.

I'm generally very inexperienced both with Tor (I've been reading papers
and specs, but don't know my way around the source yet) and with
programming C in the real world (contrived class projects are basically all
I've done), so there will be a lot to ramp up to.

Given the above time and experience constraints, I want to 1. do something
that is not urgent/blocking; 2. stay as far away as possible from
security-sensitive code, and 3. bite off something that is doable,
including ramp-up, within a semester.

Going through the "Hidden Services need some love" blog post, I found the
item "Analyze Hidden Service Circuit Establishment Timing With Torperf"
fitting. From reading the tickets, it seems like I would need to add some
instrumentation (#3459) and then do the measurements.

Some questions:

- Is there anything else that would fit the above constraints that you need
done more? I'm starting to write the grant proposal (submission is in 2
weeks) and I can still change it to anything else. (I'll dedicate the same
amount of time to the project this year regardless of having the grant
approved.)

- Who should I report to?

- Assuming I stick to the timing analysis above, are there any specific
questions that you would like the analysis to answer?

Thanks a lot!

Cheers,
Helder
