19:03:10 <jonatack> hi
19:03:42 <laanwj> #topic High priority for review
19:04:18 <laanwj> https://github.com/bitcoin/bitcoin/projects/8 currently 6 blockers, no bugfixes, nothing chasing concept ACK
19:04:50 <laanwj> (i don't know why we still have the bugfix and chasing concept categories in high prio, we never put any PRs in them)
19:05:02 <laanwj> anything to add/remove, or that is (almost) ready for merge?
19:05:17 <ariard> because we never have bugs :p
19:05:25 <laanwj> ariard: that must be it!
19:06:01 <michaelfolkson> I'm sure there are things chasing concept too but just not high prio (maybe)
19:06:17 <laanwj> yeah, probably, if you think anything should be added just mention it
19:07:49 <sipa> hi
19:08:19 <laanwj> there doesn't seem much to discuss with regard to high prio today, let's move to the next topic
19:08:30 <laanwj> #topic Coredev updates (ariard)
19:08:31 <core-meetingbot> topic: Coredev updates (ariard)
19:08:33 <ariard> hi
19:08:36 <real_or_random> hi
19:08:55 <ariard> so we have a new country, speedy trial of france didn't work :)
19:09:26 <ariard> we got optimistic answers from new sponsors to feed the coredev fund, just a bit of legal structuring
19:09:34 <ariard> the good news, it should also cover next editions
19:09:54 <laanwj> great!
19:09:58 <ariard> i'll send a last mail next week to setup a signal group, and i think the process for travel subsidy
19:10:02 <jonatack> france is doing a speedy trial of the reset i guess :D
19:10:07 <ariard> all future communications will happen on signal
19:10:08 <sipa> so, zurich?
19:10:23 <ariard> sipa: you said the name first, you owe a beer to every attendees :p
19:10:27 <ariard> yes zurich
19:10:56 <sipa> [1 non-fungible beer token at "The International
19:11:21 <ariard> Yeah Switzerland is great we have mountains near
19:12:04 <ariard> Restrictions are pretty loose compare to other european countries, I think we'll stick to it
19:12:22 <ariard> Like worst-case scenario I can think of is travel ban of non-vaccinated US people
19:12:40 <ariard> If that happen, I'll feel sorry for our american friends but still maintain switzerland
19:13:03 <sipa> especially in the US it's very easy to get vaccinated...
19:13:05 <ariard> I've also received messages for talk scheduling, we'll folks self-organize on the signal :)
19:13:11 <luke-jr> why would it be non-vaccinated US people? O.o
19:13:12 <sipa> unless for medical reasons of course
19:13:21 <jonatack> luke-jr: legislation floated by the US congress, not swiss side yet (afaik)
19:13:32 <luke-jr> i c
19:13:48 <luke-jr> last I heard that was destination-independent anyway
19:13:51 <ariard> luke-jr: yeah swiss has committed to not harden the restrictions and instead call on personal responsibility
19:13:58 <achow101> apparently the US is currently requiring a negative covid test to enter the country, regardless of vaccination status and citizenship
19:14:12 <ariard> here: https://www.admin.ch/gov/en/start/documentation/media-releases.msg-id-84676.html
19:14:14 <achow101> this could pose some issues for return
19:14:37 <ariard> achow101: you mean US -> Switzerland or Switzerland -> US ?
19:14:47 <achow101> switzerland -> US
19:15:14 <jonatack> luke-jr: https://twitter.com/RWMaloneMD/status/1426884920295755783
19:15:30 <jonatack> https://www.congress.gov/bill/117th-congress/house-bill/4980
19:15:32 <ariard> achow101: yeah a negative covid test is pretty the norm for any cross-border travel those days
19:15:59 <gleb7> that was also my experienw
19:16:02 <ariard> achow101: i expect tests to be pretty available in zurich?
19:16:28 <sipa> i can't imagine that that would be a problem
19:16:51 <ariard> yeah that zurich, ch not bitcoin beach, el salvador :)
19:17:08 <michaelfolkson> I'm assuming there will be teleconferencing for Aus, NZ etc? At least for some sessions? Getting balance between privacy and openness to those not present is always tricky
19:17:32 <sipa> that would be very hard i think
19:17:43 <luke-jr> michaelfolkson: if it were possible, it'd make more sense for everyone to tele
19:17:51 <michaelfolkson> I guess...
19:17:52 <sipa> coredev isn't really organized... lots of just random people starting a conversation
19:17:55 <luke-jr> but the point of in person is that it's in person
19:18:02 <michaelfolkson> Ok
19:18:09 <luke-jr> (and the benefits you get from that)
19:18:24 <gleb7> I think we should ask aus people of what they think they could use from the meeting, based on the previous experience and their personal view of productivity.
19:19:09 <jonatack> michaelfolkson: i've never attended coredev, but i imagine previously holding some of them (roughly one in three?) in tokyo helped with this
19:19:20 <luke-jr> (also reminder that not only aus/nz are isolating)
19:19:36 <michaelfolkson> Right, those are examples I know of
19:20:25 <ariard> Yeah I'll reach out to aussies if they have topics to propose
19:21:16 <ariard> And last thing, if you wanna to stay for the weekend feel free to do so, few people were willingly to do outdoor activities/team building :)
19:21:31 <ariard> voila voila, the following on signal
19:21:37 <laanwj> thanks for the update ariard
19:22:08 <laanwj> #topic Erlay update (gleb7)
19:22:08 <core-meetingbot> topic: Erlay update (gleb7)
19:22:13 <jarolrod> thanks for the update!
19:22:44 <gleb7> Okay so to move forward with erlay I created 2 meta-issues in my repo. I want to use them for discussion, as I need some help at this point.
19:23:01 <gleb7> First, there is an issue describing all the stuff going on with transaction announcement bandwidth.
19:23:07 <michaelfolkson> Chasing concept? :)
19:23:29 <gleb7> After protocol change we agreed on with greg and peter lately, the overall node saving is probably gonna be about 15-30% bandwidth...
19:23:50 <gleb7> So for example I wanna hear that we are willing to add complexity and that's justified by the gain.
19:23:58 <sipa> gleb7: how much was it before?
19:24:25 <gleb7> sipa: i claimed to save up to 50% in the paper (for 8 conns)
19:24:50 <sipa> but higher numbers with more connections, i assume?
19:24:55 <gleb7> yes indeed
19:25:15 <sipa> because that's the real justification - having sublinear bandwidth growth as the number of connections increases
19:25:38 <gleb7> I was thinking about that as well... Connectivity increase doesn't necessarily mean tx relay over them, right?
19:26:01 <gleb7> Relaying txs over more links is good too (for compact blocks, for privacy potentially)
19:26:12 <sipa> block-only connections are an obvious way of increasing connectivity without increasing bandwidth (much)
19:26:34 <sipa> but ideally, with erlay you should be able to get nearly the same
19:26:42 <gleb7> that holds.
19:27:08 <gleb7> Also, there is a bandwidth/latency trade-off again. A bit slower relay gives better bandwidth savings. That's also to re-discuss probably.
19:27:13 <gleb7> So yeah here's the first link
19:27:22 <gleb7> https://github.com/naumenkogs/txrelaysim/issues/7
19:27:46 <gleb7> A lot of high-level text, enjoy and comment please :) Be ready to allocate maybe 10 minutes for that read.
19:28:01 <gleb7> The second link is an invitation to join my experimental erlay mainnet nodes.
19:28:26 <gleb7> I run 8 nodes with erlay enabled, just connect to them and see impact (instruction provided).
19:28:33 <gleb7> https://github.com/naumenkogs/txrelaysim/issues/8
19:28:42 <sipa> i will join
19:28:55 <laanwj> should i add that issue to chasing concept ACK in high prio for review?
19:28:58 <gleb7> So there is room for help from both high-level and practical thinkers :)
19:29:13 <gleb7> laanwj: it's not even the core repo currently... although I could move it to core?
19:29:26 <laanwj> that doesn't matter for the project board, at least
19:29:42 <gleb7> ah, yeah, then probably add the first link? That might get some attention
19:29:43 <michaelfolkson> Get it in there
19:29:51 <laanwj> done
19:30:05 <gleb7> Thank you.
19:30:15 <gleb7> I'm done with my topic.
19:30:40 <sipa> nice seeing progress
19:30:48 <michaelfolkson> You want to follow up in next week's meeting or in two weeks gleb7?
19:30:53 <laanwj> i'll try to help testing too
19:31:02 <michaelfolkson> For people who have read it, looked at it
19:31:05 <gleb7> michaelfolkson: sure, but at this point it's more about people getting involved :)
19:31:46 <gleb7> Like, my part for now is kind of done. Once more of us join, we make next steps.
19:31:58 <jonatack> thanks gleb7, i was wondering what the status was, will have a look
19:32:56 <laanwj> any other topics for today?
19:33:19 <michaelfolkson> I'm assuming if you run this Erlay node that it functions as a normal mainnet node other than when it connects to other Erlay nodes?
19:33:45 <gleb7> Sorry, I don't understand the question.
19:33:55 <gleb7> ah, yes, correct.
19:33:59 <gleb7> At least it should be :)
19:34:22 <michaelfolkson> Cool
