* Sponsor 28: update? * phw on #30716 - Improve obfs4's flow obfuscation * we want to improve obfs4's flow obfuscation and find a way to "regulate" per-packet entropy, so a high-entropy filter cannot easily block the protocol * our georgetown colleagues are evaluating obfs4 * cohosh continues work on snowflake * We are getting some more snowflake volunteers, it's probably time to update our CONTRIBUTING.md guidelines: https://trac.torproject.org/projects/tor/ticket/31847

- Coded ansible recipes for gettor so that the service can be easily maintained by more people: https://dip.torproject.org/torproject/anti-censorship/gettor-project/gettor-... - Fixing some issues about git history taking too much space quota on gitlab and github

Next week - use archive.org as new distribution endpoint: upload files to archive.org - reach out to irl about sending gettor stats to metrics - review specs: are specs up-to-date? should we change something in the specs? - review docs: write documentation for web site and ansible playbooks.

Help with: - waiting to be told that's fine to upload files to archive.org? Can we start? - review new website. New website should be reviewed. https://dip.torproject.org/torproject/anti-censorship/gettor-project/gettor-... phw: This week (2019-09-26): * Filed #31807 for outdated documentation of "BridgeDistribution" in tor's man page and wrote patch * Updated documentation for obfs4 docker image, advising people to use 'latest' tag * Moved exitmap-modules from private GitHub repository to dip.tp.o * Started working on language switcher for BridgeDB (#26543) * Tricky because it involved convoluted 3rd party library * Helped add new default bridges to Tor Browser -> will be in next alpha version * Worked with prospective operators of new private and default bridges * More work on obfuscating obfs4's flow signature (#30716) * Also made obfs4 client store state (only server would do that) * Still no progress on reducing per-packet entropy. It's tricky. * Filed #31834 to improve usability of obfs4 docker file * Had a chat with a researcher who was trying to understand (D)DoS attack against Tor Next week: * Make progress with obfs4 improvements * Figure out how to reduce per-packet entropy Help with: *
