== Discussion ==

- We want to run a session during IFF to get people to circumvent censorship. We were thinking of getting people to connect to a censored network, e.g by providing a router that censors in different way; and try to access the internet or some sites or something. We would need some advice/help to set something like this up -- Pili & Gus

- Source code from 2017 experiment (few hundred users, Windows only, simulated censorship with a local firewall, used an instrumented Tor Browser to record mouse clicks):

- https://github.com/lindanlee/PETS2017-paper

- see experiment/firewall.bat and experiment/gen-firewall

- see the screenrecording directory

- see the session/pre/videos directory for videos and detailed notes of a pre-study

- see the setup directory for other setup notes (don't remember what exactly)

- paper: https://censorbib.nymity.ch/#Lee2017a

- Source code from 2015 experiment (5 users, one on one, no censorship, just browser usability):

- git clone https://www.bamsoftware.com/repo.eecs.berkeley.edu/tor-ux.git/ (see README and tasks.html)

Help with:

cjb: 2019-02-27 Last week: - got feedback on #31011! Next week: - #31011 grew into "get tor to parse extra-info docs and their transport lines", am learning how to do that with help from teor - poke at golang snowflake proxy Android app Help with: - perhaps it makes sense to split out the bridge-side change in #31011 from the bridgeauth-side change, since the bridgeauth-side change will take longer, and the bridge-side one will take time to ship and get people updated to..?
