A new topic to add: moderation of Discourse forums.

We’ve been getting a lot of spam recently. We could use volunteers to help moderate the forums. It’d be a good time to discuss what guidelines we need and what settings we can change through the Discourse interface. (cc: @breckbaldwin, @seantalts)

Does flagging the spam posts help in any non-negligible way? I see that it removes the post for me, dont know if it hides it for other too.

Yes, it does! Thank you!!! (to you and Dan Simpson and whoever has been flagging posts actively)

We have a lot of flags we can set, though. That might help cut down the problem a little bit.

Hello to all the jetlagged folk in Cambridge (it it’s surroundings).

Is there a schedule for these meetings so that I (and other unfortunates who aren’t physically present) can join?

Dev meetings as listed on the schedule, they are setup to encourage them to go long into breaks/lunch.  
Tues/Wed  
11:30am for an hour abutting Lunch  
3:30pm for an hour, abutting end of day/happy hour  
Friday 1-2pm but that is more constrained.

Setting up hangouts makes sense. I don’t have the cycles to make it happen.

The schedule doesn’t list the topics being discussed at each meeting. Can someone please update that?

(Edit: “someone” is probably @seantalts. Tagging because everyone’s probably horribly jetlagged.)

I would like to see progress on this. @yuling is one relevant person.

@stevebronder made a poll for the topics. I just noticed that the poll required to click Vote for each topic separately and it was not enough to click vote below the last topic I chose. I hope others have not made the same mistake, but it is likely as the last topics have much more votes. Please check your votes and we can then assign the topics first for certain dates. Also please vote if you want to participate via video. The topics with more 4+ people will have priority in scheduling a fixed time and the topics with less people can be more ad-hoc.

It seems no-one else did check their votes as there are no changes. Based on the current results the schedule is

The location is where the registration and welcoming words were, that is, [Chetwynd Room](https://mc-stan.org/events/stancon2019Cambridge/img/annotated_kings.pdf) and [Keynes’ Hall](https://mc-stan.org/events/stancon2019Cambridge/img/annotated_kings.pdf).

@Matthijs @rok_cesnovar @enetsee @tadej and I want to talk about stanc3 compiler optimizations I think on Thursday or Friday as well (based on Rok and Tadej only being here those two days).

The trick will be finding time - on Friday it looks like the sparse matrix stuff is supposed to be 1-2pm and we don’t have other dev time outside that. I think the optimization stuff will take longer than 30 minutes and I imagine the sparse matrices will as well. Can do the sparse matrices on Wednesday 1130-1230 and the stanc3 optimization lib on Friday 1-2pm?

Any chance we can swap these two so I don’t have to talk about sparse matrices before 9am?

Not sure where now parallelisation landed… but I have to leave on Friday shortly after lunch… so Friday 1-2 would not work for me, unfortunately.

I thought “parallelization, optimization, KINSOL” were all the same and I was proposing moving it to Weds 1130-1230, does that work for you?
