== notes ==
- thanks to everyone involved in any way with ELC and DevDay!
- still have AB instability
- still looking for more maintainers
- looking for way to attract and thank contributors
- lots of unassigned bugs we’d like to see for 3.2 (see unassigned bugs)

== general ==
RP: happy to have some things fixed in AB, but still issues

RP: thanks to everyone involved in ELC and especially the Yocto DevDay

Timo: i see the perl update was merged, but it seems like lots of things
were dropped (RDEPENDS), so i predict there will still be issues with
RP: i noticed that too, the AB was all green
Timo: we’re probably missing tests

Saul: heard a rumor about Stephen
Stephen: that i’m retiring? yes, next week. but i’m continuing on as a
volunteer with YP
Randy: how long at Intel?
Stephen: 34.5 years

RP: ? licenses are inherited globally, are people using the license package
JPEW: we display the generic and specific license because they’re there
SS: customers i’ve known have always used just the generic
Randy: WR has its own code for analysing the code to pull licenses, but
customers appreciate having the generic
Peter: we have to go through the code to sort out the 20 different variations
on GPLv2, a mess!
RP: it’s been pointed out to me that the checksums of the generic license
files are not checked, so if there was ever a change in the generic text,
there isn’t anything that would alert the users
Peter: is it meaningful to use checksums for the generic text? that’s not
the same case as the license of some upstream code changing
RP: well, if that changes then the task-hash should change which is supposed
to case rebuilds etc
JPEW: there was a bug filed
RP: this shouldn’t be happening, but there are probably other “games”
going on

RP: is anyone using the SPDX class from OE-core? i hope the answer is
“no”, i imagine it’s quite broken by now. i have a patch i plan to
Randy: i don’t see WR using it (quick look)

Timo: i was looking at patchwork again, is there somewhere we can run a test
instance somewhere for testing
Michael: vm at digital ocean currently, i can create a staging instance on YP
hardware. who else will be using it?
Timo: Amber, potentially. i’ll give you an update
Michael: i’ll spin up something new, the current is ubuntu 16.04 so it needs
an update anyway

TW: how did the booth go last week at ELC virtual?
Philip Balister: the interface for the booth was clucky, didn’t get any new
Timo: i had one interesting contact at the booth, but it didn’t go as well
as it could have
Josef: not a lot of new folks, got a lot of people contacting me in thanks
for the live coding stuff, lots of contacts from the middle-European and
south-central Asia, we have lots of contacts in west Europe and NA, but
need to develop more in the other areas
RP: this would be a good question for the advocacy list
Randy: do you know what sort of communication would work best?
Josef: lots via linked-in, stack overflow. irc and email are not that popular.
lots and lots in twitter!
Timo: agree with twitter

Timo: what did people think of using slack?
TrevorG: hard to know whether to reply in-line or as a thread
Philip: feel it’s terrible for open source to use slack (free version
loses history, bad optics). gnu radio tried slack, moved away. recommend
JPEW: slack can work if you have the ability to create arbitrary channels
(which wasn’t available with the ELC slack)
Scott: the mattermost interface has better handling for threads, a “best of
both worlds” between slack and irc
Timo: gitter (meta-python, etc) works better for me. i agree with Philip that
the thread thing
Philip: i’d be curious to see a mattermost try
RP: matrix might be a good way to bridge both worlds (traditional use irc,
younger crowd using other things)
Philip: matrix worked well for gnu radio
Paul: agree with others that slack wasn’t that great, but think that we
should explore other technologies
Timo: looking at what Fedora has done, it’d be great to see more
integration. e.g. reports from AB reported live
Khem: i’ve used matrix and like it, can’t comment on mattermost, i think
Fedora is also using discourse to amalgamate email, irc, etc. matrix is
nice because you can edit, so the log looks better than irc
RP: resources, risk of forking the community (some follow email, some follow
A, some follow B) i’d like to have a central dashboard but we need to
find resources
Paul: people who use a given technology might not be the people to are
interested in various aspects of the project
Timo: i like the idea of integrating
RP: it sounds like it can all be integrated
Balister: if the bridges aren’t setup properly it can be detrimental
(PaulB has visions of messages going around each platform recursively forever)

Timo: how did people feel about the hands-on sessions?
Khem: i think it went well in general, in-person would have been more
TW: usually there are 2 tracks, break-out rooms
Khem: virtual is much harder, hard to get people the help when you’re not
sure who is at what stage, people have to speak up
Timo: in the past sometime we would just get to jump in and give people a new
TW: hard to know who’s struggling, no feedback
Timo: large numbers too, glad to see the number of participants, but the
larger the class, the harder to manage.
Rob Woolley: https://github.com/conan-io/training?files=1 did a hands-on that
i thought was really well done. instructions on git, thumbs-up to say
“i’m done”, scripts to get people caught up
Khem: yes, good idea!
Josef: unfortunate that the biggest devday ever had only 1, mostly advanced,
track. and the first couple talks were on advanced details (licenses,
Scott: i think they were merged because beginner numbers were going down
Khem: we should have separate rooms
RP: there was a definite trend, in real conferences, esp in NA towards
intermediate/advanced talks. beginner attendance higher in europe
Khem: lots of people from everywhere around the world
Randy: why wait for the next conference? maybe do this monthly
JPEW: was there a survey?
various: yes

Timo: i really missed not having an OED{E|A}M
Philip: board is talking about it
TW: what about #oe-meeting on irc, we had a couple a while back
Philip: give us a bit of time to figure something out. nice that we don’t
have to put it against ELC/ELCe

Timo: want to give a shoutout to Josef for his working especially bringing in
new people via his Twitch streams
Josef: thanks! lots of neat stuff coming up. we’re over 32k views in last
few months, 150 new followers each week
