I think that's good, the review even says short-term is no question. 17:04:12 then, we can have a look at the resulting data and reconsider if we see any anonymity problems 17:04:13 o/ 17:04:14 great 17:04:43 +1 17:05:03 great, i'll try to move forward with the bridgedb patch over the next few days. it's about halfway done. 17:05:20 what kind of implementation are we talking? I know I suggested some wild-eyed ideas. 17:05:34 didn't mean to create a lot of work. 17:06:41 dcf1: for now, the first four points in section 4 of: https://lists.torproject.org/pipermail/anti-censorship-team/attachments/20190425/d76339db/attachment-0001.pdf 17:06:49 sorry, section 3 17:07:15 i'm open to including heuristics too as they are very useful but i think we need to think a bit more about how to do this safely 17:07:22 ok 17:08:02 section 4 has an example of a potential issue with the heuristics. let me know if i'm wrong or unnecessarily concerned 17:08:48 First 4 points sound good to me. 17:09:26 ok, we have two action items on our agenda 17:10:07 first, if you have experience with our pluggable transports spec, please respond to the following thread with your feedback: https://lists.torproject.org/pipermail/tor-dev/2019-June/013879.html 17:10:44 (this is part of our effort to improve the PT spec. in the first step, we're compiling all the shortcomings and suggestions from implementers.) 17:10:51 you may want to include twisteroidambassador on that thread (https://github.com/twisteroidambassador/ptadapter) 17:11:06 i've already pointed several implementers (e.g. from psiphon, lantern, and i2p) to it 17:11:09 That's the only manager-side implementation of the PT spec I'm aware of, other than Tor itself. 17:11:37 oh, thanks dcf1 17:12:42 Oh, and I think Operator Foundation may have an implementation (of PT 2.0), offhand I'm not sure if it's manager-side or plugin-side only though. 17:13:14 yes, brandon sent me some links. i'll add them to the ticket after this meeting. 17:13:34 do we know the shadowsocks people? do we think the free beer person on the mailing list is a shadowsocks person? 17:14:17 fyi, we started collecting PT spec implementations here: https://trac.torproject.org/projects/tor/ticket/29285#comment:5 17:14:18 phw: the tunnelbear people use obfs4 right? do we know if they use the PT API side of it? 17:14:45 arma5: good question, i don't know. i'll see if i can get in touch with anyone from there. 17:15:41 "there" being tunnelbear and shadowsocks. 17:16:45 our second action item is about stockholm. if you want to attend/lead any anti-censorship sessions, please add them to the following pad: https://pad.riseup.net/p/_kDAK09C16xL2lBRQ7sJ 17:17:54 any other impromptu discussions/announcements? 17:18:32 ok, let's move on to "needs help with" 17:19:11 * phw notices that cohosh has some "needs help" items 17:19:43 i already pinged GeKo about the windows toolchain item 17:19:46 I'm still planning to look at #29206, sorry I've had some other projects to work on 17:19:56 dcf1: thanks! and no worries 17:20:31 i'll do my best to review #21315 17:20:54 phw: thanks! 17:21:10 cohosh: it might need to wait a bit more :( i won't get to it this week anymore and am at mozilla's all hands next week :( 17:21:30 phw: i emailed you a tunnelbear contact 17:21:35 thanks arma5 17:21:56 GeKo: no worries, thanks 17:22:51 i think we're good for today. anything left? 17:23:25 #endmeeting
