[18:06:23] <Toke Høiland-Jørgensen> Don't think the WiFi on the boat would be up for this
[18:06:53] <dave.taht> well, you brought your own router... you might have been able to talk the captain into fixing their satellite uplink.

[18:13:13] Ron Velt joins the room
[18:13:19] <Toke Høiland-Jørgensen> I see slides on meetecho; but moving the camera to point at the speaker instead of the chairs would be good...

[18:13:41] <Meetecho> Toke Høiland-Jørgensen: done, sorry about that!
[18:13:45] <Toke Høiland-Jørgensen> Thanks!

[18:31:19] ronald in 't velt joins the room
[18:31:19] ronald in 't velt leaves the room
[18:31:19] <akatlas> is anyone relaying jabber comments?
[18:31:36] <akatlas> or Dave - can you raise your hand in the meetecho so the chairs can push the button and add you to the list?

[18:36:33] Mezgani Ali_1033 joins the room
[18:36:52] <dave.taht> hmm

[18:45:19] <Barbara Stark> slide 13
[18:46:06] <Toke Høiland-Jørgensen> I like the idea of using AE. And I would say that not being able to parse a sub-tlv in an update you don't fully understand is a feature...
[18:47:03] <dave.taht> AE is good. I do kind of think we end up with more than one new AE. Do we end up with a mirror image of the existing 4 AEs?
[18:47:42] <Toke Høiland-Jørgensen> +1 to what David is saying
[18:48:11] <dave.taht> question - do we only end up with one AE?
[18:48:18] antonin.decimo leaves the room: Disconnected: closed
[18:48:18] antonin.decimo joins the room
[18:48:36] <Toke Høiland-Jørgensen> Bird will also dorp the entire TLV if it doesn't understand the AE
[18:48:42] <dave.taht> AE for... sake of argument - MPLS?
[18:48:56] <dave.taht> what other AEs are possibly needed?
[18:49:09] <dave.taht> thx barbara!
[18:50:50] <dave.taht> can we have a combination of 2 and 3?
[18:50:57] <dave.taht> with sheet music?
[18:52:40] <Barbara Stark> slide 16
[18:55:08] <dave.taht> I do plan to write up something by the end of summer, but :whew:
[18:57:28] <dave.taht> would you like to offload the applicability statement editoriship? or editorship of anything else?
[18:58:11] <akatlas> @dave.taht: Just relaying Julius's love for you (I assume more your offer ;-)
[18:58:39] <dave.taht> (it's partially because I want to put a few of the lyrics from 2, back in 3)
[18:59:03] <dave.taht> but sure, I'll tackle the applicability statement, if he wants.
[18:59:08] <Toke Høiland-Jørgensen> Could we get the camera on the speaker again?
[18:59:49] <Barbara Stark> https://www.ietf.org/proceedings/98/slides/slides-98-babel-multicast-babel-extensions-00.pdf
[18:59:59] <Meetecho> dave taht: we still see you in the queue, if you've finished can you use the hand icon to release the floor?
[19:00:29] <Barbara Stark> Sandy Zhang presenting
[19:01:18] <dave.taht> strong, strong objection to the sub, sub type. (ae?)
[19:01:24] dave.taht grabs coffee to think about it
[19:03:15] <Barbara Stark> Dave: Do you want your objection audibly expressed?
[19:04:30] <dave.taht> nope
[19:04:35] <dave.taht> bingo. :)
[19:04:40] <dave.taht> (from jch)
[19:04:47] <dave.taht> go back on the slide please
[19:07:25] <dave.taht> I would like very much for babel to remain parsible with a forward only parser such as this: https://github.com/grg/parser-gen.git
[19:07:32] <dave.taht> we can be expressed in verilog.
[19:07:37] <dave.taht> (which can be)
[19:08:49] <dave.taht> I can no longer even raise my hand.
[19:10:01] <dave.taht> barbara: if you could mention my "I would like very much..."
[19:12:40] <dave taht> heh
[19:12:59] <Gabriel Kerneis> I am
[19:13:00] <Gabriel Kerneis> thanks
[19:15:23] <dave.taht> groovy - using bpf to extract actual traffic stats per installed route would be nice
[19:15:31] <dave.taht> (no need to restate)
[19:18:03] dave.taht claps
