Drop projects/mentors we haven't heard from
Dropping the folks we haven't heard from with regard to GSoC. For projects where they're the last names remaining dropping the project itself too. --- getinvolved/en/volunteer.wml | 307 +------------------------------------------ 1 file changed, 3 insertions(+), 304 deletions(-)

Our unit - test coverage is shamefully low, and the dependency graph of our modules is - shamefully convoluted . We could use refactoring and unit tests! Please - look through the Tor source code and look for ugly or tricky code or - dependencies -- the uglier and trickier the better -- and think about how - you could make the code look better, read better, and (subject to testing) - work better. - </p> - - <p> - If this is for a fun side-project, it would be great for you to work on - anything that can be made better and more tested. For an internship-level - position, we'd hope that you could find a number of particularly tricky or - knotty piece of the code to clean up, and aim for resolving the ugliest - problems, not necessarily the easiest. - </p> - - <p> - For a big project here, it would be great to pick one of the major - "submodules" of Tor -- path selection, node discovery, directory authority - operations, directory service -- and refactor its interface completely, to - minify and codify its points of contact with the rest of Tor. - </p> - - <p> - <b>As part of your application for this project please identify one of the - thorniest Tor functions and submit a patch refactoring it to be better.
