A

B

Then welcome everyone on December 4th. It doesn't 1910 astok working group, a tion, so let's see the agenda. Does anyone has okay? Let me share my screen. First is anything in your mind in the mean time which is not on the agenda, you would like to discuss.

A

Should we talk at all about next week in the collaborator summits.

B

It's a good idea.

B

Okay, do you see my screen yeah.

B

Is there a talk or you should believe it? This.

A

Jewish, if nothing else, there's a proposal in the club submit I think do you have that, like Jewish.

C

C

B

Well, there's two actually.

C

B

You see the agenda, which is on my screen, yeah.

C

I I guess that's a go from the organizer still setting it up.

C

A

Anything I think it may have been based on how much time you asked for or mmm-hmm but I know they are. That was like a first draft from what I hear now, there's actually gonna be like two streams. So, okay.

B

B

Okay, so it looks like could be a general heads-up to the members sounds like.

C

Yeah, basically, the way I plan to lay out his weight effect history about the.

C

How we catalyze postmodern working group and agnostic working group as to truly separate working groups with slightly different objectives, but then got merged in twenty twenty eighteen of its me that this majority or the goals are kind of for mapping. Things like that, and then the I plan to talk about each of the in diagnostic tools and current capabilities versus he known these gaps like and then ask for participation all for action on that particular tool. Then you also talk about the best practices.

C

You use a journey based approach again advocate for why the tooling has to come from the use case and I use the journeys perspective, and you know make a better call for participation on the documentation as well as looking at improvements on the tool side. It.

B

Sounds like it will be more, an informal or rather than a collaborative session. Basically.

B

It may be one thing that you could ask the opinion of the people. Is the timing? Isn't it would be a good forum to discuss that? What.

A

Reason did have a you tried with you, try to Google for the time right.

B

Yeah I'm just saying that, probably in person sure yeah.

A

I'm, just trying to remember did we find a new time that was any better or we just get stuck on that one.

B

Last week could be discussed if you didn't find any overlapping and the alternative solution is, we can have two times or we can try to pick a different day right.

B

So do you plan to use both slots, which is on the agenda or only one.

C

Of them definitely not.

A

How much time did you ask for just an hour I asked.

C

For a table, yeah yeah.

A

So that should have just been one slot: you're right, that's probably just a mess.

A

Missa mix, misunderstanding or something so it like this in terms of who we thinks gonna, be there I think Juhi she's got the right thing, because there's only I know I'm gonna, be there jury, she's gonna, be there I, don't know who else is gonna? Be there? So, in terms of a working session, doesn't sound like we have critical mass.

B

Yeah it's hard to tell from the people who we used to be on this call, but not on this call. Yeah there'll be two person from Netflix from my team, so I know that they are not in this group and conversation, but if you need any help or information from them, okay, who's that it will be real and.

A

Gimme, okay, yeah be nice to say, hi bacon. You can ask him to come by the IBM booth or something like that.

A

I'll, be there like 6:00 to 8:00 on Wednesday like 660 p.m. it'd, be great I, think William I've talked to yeah.

B

He used to work for not sauce before or and he joined ethics more than two years ago. So I expected.

B

D

B

Also active on the tc39 he's a wonderful representative, Allen okay, so that can be interesting if you wanna join efforts between that group and this group yeah.

A

I would be interesting, like Joe. Is our tc39 contact too? So again, it's a good opportunity to get them together.

A

And we had talked about the one related tastes and cooks going to tc39. So that's that's one area where we've seen it could make sense. Okay,.

B

I have this feeling that, like the community, really need to figure out ownership boundaries, because now we have the whole country, yes and Java, Sea Peoples there and the node and like this working groups, it's for me a little bit blurry. We need to figure out the ownership of what I mean, just like just like specific solutions features I mean that we open basically the foundation to more generally to the language. Yep and I had this feeling on the last collaborators summit. But we are talking about lots of different things right.

A

Yeah, the yeah, the clubbers Irma, definitely is open to look to lots of different things. I think there are still lots of node focus stuff because it'll probably take a little while for the other projects to figure out how they want to get involved.

B

D

Can you hear me? Yes, all right, I'm having some connection problems, so I might freeze or something came I noted before the meeting that I have some questions, but they resolved last weekend at the hackathon, where I've met some people. Who could help me out? Okay, so I didn't prepare any document or something and sling that in the agenda right now, you didn't want to do.

A

Work-Related tasting, though right yeah.

D

All right, yeah so.

A

We might maybe it's worth. We have that on the agenda, it's worth getting. You know an update on your plan and you know, and just talk about so that we understand what you're trying to push forwards there and how much time you have that kind of stuff.

D

Right now, I'm just like looking at the topic in general and trying to like committing some stuff related to it and trying out some basic diagnostic tooling with it, but I.

D

So right now, I'm not planning on contributing active to the three.

D

Async hook topic: okay, yeah.

A

You're, basically do more in the learning.

B

Do we have anything further collaborate or something that we should discuss.

D

Yeah my side, I.

C

Would sing that, from from the list, a prepared couple of things I'm still looking for clarity's around.

C

V8 CPU profiler do we know that is it being used in the production by anybody and what is the trade-off between v8 CPU profiler over the profiler? Do we have any idea.

A

Did you look to see whether rap metrics is using that versus because I know it has a CPU profiler built into it? Isn't.

B

It the main input of which is the name from people beard clinic.

B

Yes, what the clinic has the CP profiler, which is awesome, 0x.

B

Mm-Hmm Xerox uses the CPU profiler I'm, not completely sure, but at least the previous version was using. It I'm, not sure, okay, because I remember that mata was telling that they use it, because it's compatible with every platform.

D

B

Right as opposed to having to have the platform specific ones based on the comment, it looks like.

C

This one provide produces a JSON formatted output, so it has to be platform independent and.

C

Pretty straightforward but I mean from the usability perspective, I'm just wondering all right, I wouldn't expect.

B

To be honest, that lots of people are using it without these tools because it doesn't come with a good visualization before yeah.

C

Yeah, that's I, guess that's I had a little note. I had some queries at the pace have provided lot of information in the issue document is called provide more on the ll node front. That should be enough information for me to just through all the tools and provide highly you know: high-level abstraction on the capabilities challenge.

B

Do you need anything else.

C

If yes, I will.

A

There, the only thing that comes to mind is Peter, I, think you'd mentioned trying to have a summit or something at Netflix I. Don't.

B

A

B

A

You mentioned that you were thinking about trying to have a diagnostic summit at Netflix sometime next year. Yeah.

B

We would be happy to host. I I didn't ask other I know that in the California office we can host it anytime. Basically, we have a really good infrastructure, and in for that we even have technology probably to make it like streaming and people can connect it.

B

So I asked what I would need information is that boot people willing to to come 2006 semi just in general, would they come to California for the more sync in European or Asian office? That's probably harder, because we have lots more offices there, but.

A

Maybe possible I'm, just thinking like at the summit. Maybe if you have a set of questions that we can ask to say hey, this is one of the things that you know is being thought about. Would you be interested in coming or whatever? So, if you could provide those questions, we can ask them there good.

B

Idea, to be honest, it's really like it's to question like the willingness and like when and where you think we can really host it at any time and you would I think it would be really useful if you would have a 10-6 I mean. So it's really up on the people if they are willing to come, and what's this a friend so.

A

Maybe we can like it's it's like if I just so we have like. Would you.

A

Come in, where would the most likely.

B

Place in Europe II, probably I'm, stunned I, have to ask but as I know, that's the biggest office.

A

Right like if we just ask those questions right, like you get a, would you come with us here when you come off this air and then that gives some data just to say from at least that sample of the audience and.

D

What child do you use to reach out to the people.

A

This we're actually gonna ask at the conference itself like in the there's a summit in the collaborator summit. You are right, like we should probably open an issue after the summit saying hey, we ask these questions and here's the here's. The answers, you know add your your thoughts as well, right or I. Guess the other way to go would be like Peter. If you wanted to open an issue and the repo, maybe there already is one we could point to that one and ask people to I can.

B

Open issue, but, to be honest recently, I feel people are not really responding on the issue right I agree, so the personal touch is I. Think critical.

B

A

Do we ask first, then and then open an issue that captures it just to tap document it and see if we can go from there? Okay, so Jewish I'll, try and remember. If you can try and remember.

B

Is there anything really to collaborate? Listen.

B

The next item is the usage Chinese best practices. Let's discuss them one piece. Last time we continued working on the on the process crashing use it journey and basically, we filled out with existing tools and user journeys. So two things is missing. One is one is come up with an ideal user journey where we want to be in the future and another one is kind of documenting what we have today. I feel that maybe maybe documenting what we have today would have a bigger impact, the community.

B

So the question is: what do we need for that to to make that happen?.

A

In terms of sea filled, is there an issue to open to take a look at the I? Have.

B

A have a Google, Docs yeah, actually.

A

B

Have I have it here and I will link it in.

B

haha I'm such a suit, so nope.

B

Okay, I find a check.

A

Specific blockers or just needed more time working through no.

B

Blockers I mean first of all, we which should I say, move this information to do before in some way, I like of the Google Docs and another thing is I mean the long-term goal would be to capture the vision and the short or mid term goal is to document the current tools and how to use them. Yep, we kind of started to document the code down with the diverse document, so I think we should just just keep continuing.

B

Maybe we should kind of assign people to the specific user. Chinese like it sounds like we have one, which is a diagnostic report.

B

And the lar node.

B

Yeah, it looks like I mean with these calories of the walk range except or we can. We can document it but copy this Louis priority. So.

A

Of those three I'm, just looking at it like I, could take the valgrind one hello. No, it sounds like if we could get Mateus to volunteer yeah.

B

I see nothing's people can definitely take the note and then Jewish.

A

You're, probably the best for the diagnostic report right.

A

And yeah it would be good, like we've got it's under the diagnostics, documentation right.

A

Just like is it this cuz, we added some blank documents, I think even blank though so you'd move some of the information into some documents, so does it fit into one of those Shh I.

B

Mean I think it could go to what we stopped in that structure right.

A

So we probably want to pull what's in this document over to one of those docks and then add in the journeys and in there I.

B

Don't think us said anything, but I will assign him and later if he doesn't like the idea, he can go because he's.

A

On a call, yeah, okay, that's why.

B

He's not in the waiting room. Okay, do you speak with him on other channel, because.

A

Yeah I talked to him, so let's assign.

B

A

All encouraged thank.

B

You yeah, maybe Matt I was kinda happy the system's racing, but that's like way to do. Okay, and we have these notes from the previous calls. We we should turn them to more consumers of format and also add them to the repo yeah.

A

I think that, like probably a peer that pulls them into this repo, so then it's clear where to put the sections we've just assigned would make sense.

B

I come back on converting the notes.

B

Okay, I think that's about you, sir Jamison. The command I really hope that. Finally, we are making progress on it. To be honest,.

A

Things take will seem to take a long time, that's for sure, with everybody having just a little bit of time,.

B

Okay, so next time is a Singh who's. Robin gave us buddy a heads up that is ramping up. Is there anything else you'd like to discuss about that.

D

Right now, no not I.

D

Think in the next meeting, but right now, I'm not sure because time is limited right now and I need to see where I can fit it in.

B

Okay, thank you in the same time, in u.s. returned to us like us. Yes, I.

B

Know what do you hear I hear.

B

Well, maybe he's mean.

A

Just what we see if he's gonna come back, I'm not gonna, make the next two meetings because basically holidays.

C

I'm sorry I dropped off in between.

B

Okay, the only thing what we disk only we went through the user journey document and we assigned people to ride the documentation in the diagnostic repo in the structure. What we you did guys last time, yeah and Michael.

B

Take walk round, one motto send me, took other node one and we kind of assigned to you the not report and the hope that you will take it. Is it okay, sure yeah thanks? Okay, thank you. Finally, we're making progress, and then we discuss that there is no more information, as in hooks other what Robin shared and micro static. You mention that he can make them next to Danzig working group yeah with.

A

Given the holidays, I don't know if to be the same for other people, I.

B

I would be okay to cancel it and, let's regroup in January is there anyone who thinks we shouldn't do that makes.

C

Sense to me make.

B

Sense yeah me too.

D

A

D

So I'm gonna remove.

A

Those from the calendar, then we're agreed we're.

B

Not like creating.

A

Issues and stuff, okay.

B

Then you will see each other on the collaborators on it. If you need more information, then you know how to reach us yeah.

D

B

Other than then happy holidays, yeah I'll see you in the new year yeah. Okay, thank you. I have a good one. Yeah.
