Network health meeting notes, 4 May 2020
by Georg Koppen 05 May '20

05 May '20

Hi! We just had a short sync yesterday about network health work. You can find the IRC log at: http://meetbot.debian.net/tor-meeting/2020/tor-meeting.2020-05-04-17.59.log… There was no pad involved this time, so no notes from it. Moreover, this was the last network-health meeting for quite some time I suspect as we are currently reorganizing our team structure in the wake of the recent lay-offs. There is no network-health team anymore and network-health topics will likely be part of meetings concerned with core Tor work in the foreseeable future. But details are not set yet. Georg

Do you own the dockerhub user name torproject?
by Philipp Winter 04 May '20

04 May '20

I recently tried to set up an organisational dockerhub account named torproject but the name was already taken, by a seemingly inactive user account: <https://hub.docker.com/u/torproject> Does anyone on here own this account, or knows who might? Thanks, Philipp

Anti-censorship team monthly report: April 2020
by Philipp Winter 01 May '20

01 May '20

Hi all, Here's what the anti-censorship team has been up to in April: Snowflake --------- * Merged Turbo Tunnel features into Snowflake. (Allows persisting a session across separate proxies.) <https://bugs.torproject.org/33745> <https://lists.torproject.org/pipermail/tor-talk/2020-April/045571.html> Merging into Tor Browser is pending: <https://bugs.torproject.org/34043> * Implemented measures to hand out more restrictive proxies less often. <https://bugs.torproject.org/33666> * Split Snowflake into two repositories(one for Go, one for the web-based proxy code). <https://bugs.torproject.org/33593> * Updated pion webrtc in Tor Browser. <https://bugs.torproject.org/33576> BridgeDB -------- * Moved forward with creating a feedback loop between OONI and BridgeDB. Work-in-progress code is available at: <https://gitlab.torproject.org/torproject/anti-censorship/wolpertinger> <https://bugs.torproject.org/32740> * Removed PGP support from BridgeDB. The feature has been broken for quite a while, is overly complex, and not particularly useful. <https://bugs.torproject.org/17548> * Renamed a bunch of source code files in BridgeDB, so they no longer collide on a file system that's case insensitive. <https://bugs.torproject.org/29686> * Made BridgeDB's email responder more usable. The instructions are now more clear and it will return with bridges no matter what -- even if the user's request was malformed. <https://bugs.torproject.org/30941> * Improved a Python script that tests BridgeDB's email responder by periodically sending email. <https://bugs.torproject.org/12802> * Made progress towards improving the robustness of BridgeDB's email autoresponder, so it no longer gets confused by Gmail's quoted-printable responses. <https://trac.torproject.org/projects/tor/ticket/33835#ticket> GetTor ------ * Fixed a bug caused by malformed email addresses. <https://bugs.torproject.org/34027> * Refactored to remove duplicate code. <https://bugs.torproject.org/34035> * Cleaned up logs. <https://bugs.torproject.org/34061> * Fixed a bug in the service shutdown code. <https://bugs.torproject.org/34062> * Removed a bunch of old GetTor code. <https://bugs.torproject.org/32912> Miscellaneous ------------- * Reviewed a submission for the Tor Research Safety Board. * Moved forward with creating a "censorship snapshot" that encodes how each country blocks Tor. Eventually, this snapshot should help Tor Browser figure out how to best circumvent in each country. <https://bugs.torproject.org/28531> * Built a prototype of a lightweight censorship analyser that's meant to be run by censored users. It can help us create the censorship snapshot in #28531. <https://bugs.torproject.org/30794> * Created a new mailing list for anti-censorship service outage alerts. If this interests you, you can subscribe here: <https://lists.torproject.org/cgi-bin/mailman/listinfo/anti-censorship-alerts> * We organised two reading groups, in which we discussed the following two papers: <https://censorbib.nymity.ch/#Wang2020a> <https://censorbib.nymity.ch/#Nasr2020a> Cheers, Philipp

Community Council activity summary, October 2019 - March 2020
by Taylor Yu 30 Apr '20

30 Apr '20

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi all, Here is a brief summary of the Community Council's activities from October 2019 through March 2020. March 2020 The Council participated in the membership audit process. February 2020 The Council talked with some people from the relay operator community about extending the code of conduct for relay operation. It probably makes more sense to make a separate guidelines document about ethical relay operation. January 2020 The Council started a dialog with grants and communications teams about making sure the potential donors and guest bloggers are aligned with our community values. December 2019 no significant actions November 2019 The Council reviewed an existing community health concern. October 2019 The Council received an email containing suggestions for revising the Code of Conduct. One immediately actionable suggestion was to fix an incorrect email address for the Community Council. An appropriate email alias was created to work around the problem. - --- end of summary --- This summary will also be posted on the Council's wiki page. If you have any feedback about this summary format, or any other feedback to the Council, please contact us at tor-community-council(a)lists.torproject.org. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQGcBAEBCAAGBQJeqjBDAAoJEKMvF/0AVcMFQoML/iKK2UbDWpbBQjweas22EROF MDSIgoBD35ywGV7qlWUNO/sZCFhgs/c4HSsmC2xCvUD1FjF/J9YBDzIHmCX6Ew4o TkK39/yAo3P+IbRFDxcNcEPaGT/8MqlpMUC6lvic5CmygLxRJeBi49j4bdXcI1to 7M0Omi2cbK7RFUQCxk6VrmSuE+C/NwUbEZPzCRQgzDXPFtoecIip6EtbupciDFFz ePRItO6mlyqpBoqex+f5TrxDfhuvmqGpD4ld93azsWWO2dFK9M8pMt+cNnxA/lMl KCoIzVO/Cy/jcQ8IkRz+TeVROQrJtpxjRCVoS55bDJYhtT3sGgLGjv0QK8N0xx9Q RC4k3rFOEpUmYaVALChSL5isxIS86m+paxvHBH5avCqBWD2vYz3UiFgNZRHzRJut DkmTQNgJzKzfpmm9KER9yleNDvb4OeboTficC6pVipAr4xmY4mgXmbrqduO75gEi m+Eo02YD+qVWJKqh0mKyDbqDd6VXYKyodfJqqwGVXA== =hYTD -----END PGP SIGNATURE-----

February Fundraising Report
by Sarah Stevenson 29 Apr '20

29 Apr '20

Below you will find the Fundraising Team's February report. Please let us know if you have any questions! ## Grants DRL: We have been working on submitting two full proposals to DRL, one for usability (joint project with Tails & Guardian Project) and another for scalability. We will submit these at the beginning of March. Zcash Foundation: Zcash Foundation granted us $50,000 to work on the Specification phase of the Walking Onions proposal[1]. Thank you Chelsea for making this connection, and to Nick for helping to write the proposal and advocate for the work. We still need funding for the proof-of-concept and implementation phases of Walking Onions. If you know someone, or some entity, that might be interested in supporting this work, please let us know! Nathan Cummings Foundation: A joint proposal with FPF we submitted was declined. DIAL Open Source Center: We submitted a small proposal to DIAL to help support the Walking Onions work. OTF: We are working on a third round of OTF revisions on the Tor Browser proposal. We submitted a Learning Lab application to help publicize the onion services work in Sponsor 30. OTF also agreed to fund an in-person meeting to do some work on DDoS protections as it pertains to high profile onion services. We submitted some informal requests to the Judith Neilson Institute for Journalism & Ideas and the Omidyar Foundation. We also met with the Internet Society Foundation. ## Donate Buttons on Website We closely monitor organic donations made via donate.torproject.org. By ‘organic’ we mean non-monthly donations generated primarily via donate links throughout our webpages. It is important to track this income because it accounted for $231,472 in FY18, $239,479 in FY19, and $334,418 so far in FY20. Small changes to our web pages can affect this income. This graph[2] shows average daily online income per month. This clearly illustrates the importance of our EOY campaign and the call to action on about:tor. There are a few other events to note in the past year. The new website launched in March 2019. The first iteration did not include a prominent donate button and the average daily income decreased until we made the donate button yellow April 26th. Then average daily income increased modestly, and increased significantly after May 26th when we added the donate link to about:tor. Since that addition, we have been averaging $600 per day in organic donations (except during the campaign when the average was significantly more.) At the end of February 2020, we saw a sharp decline in these organic donations. We suspected the redesign of /download was partially responsible. Antonela quickly added the yellow donate button back to that page and we saw donations go back up to about where they were in early February. This prompted us to take a look at other modifications and we decided to highlight the donate language on /thank-you and the donate language on about:tor will be updated upon the next release. We are also beginning plans to update donate.torproject.org and are working with Giant Rabbit to be able to make those changes ourselves. ## Events We are still planning for the major donor event in San Francisco March 26th and foundation lunch in New York April 13th. Hopefully covid-19 will not alter those plans. ## Newsletter/Email list We are still seeing around 10,000 people join our email list each month and now have over 179,000 subscribers. Since the list was so large, it was taking around 24 hours to send an email message to the whole group. Giant Rabbit made some changes to our system and now a bulk email is delivered in around 3 hours. Each new subscriber gets a welcome email a day or two after they join the list and then are offered a sticker pack for a $17 donation a few weeks after that.
