A

Wait welcome to lip p2p. This is the last of the calls today on this print. I. Don't think any of you are new, but yeah bad check out. The etherpad will be falling through it for the agenda notes. We may also go to a waffle board or postal. The links will post them in nice pad emily has already agreed to take notes. Thank, You, Emily and later for this call is going to be D as David again, I believe so das David take it away. Is.

B

The awesome cool, thank you.

B

So um let's do the same model as yes, ffs go through a quick update and then jump into a bar and also hear from gavin and box a test and all that's cool update. So as we go, I profess and just be. First, we spend a lot of time on getting interrupt like I own works at speedy works like you can now open like use, Jesse PTP randgold, good beer. We, basically all the connectivity, features again the result HD but like you can dial it up and swing back and forth.

B

That's awesome, um you own it stream isn't working. Should I wait for the seem to work? Can I?

B

Let me know: okay, awesome, cool. Ok, that was the Eureka touch peel from last meetings. Next update and Richard are you around so um yeah I am okay, uh always the side of the website. I'm, not entirely sure. I know you have forked the old I.

A

Haven't had time, I'm gonna be focusing on tomorrow morning, I know all set aside like 3-4 hours tomorrow and I will ping you tomorrow afternoon and we can go through iteration four point: oh, that's, not good! Yeah.

B

Sounds good and do you need anything from me in terms of converting.

A

From you, I just he's actually a minute I've been working on my post last week, so I'll do that tomorrow, sweet.

B

You know it's: ok, let's try to schedule something to review after you do that and because it would be like really awesome web by Def Con to like people.

A

Schedule come afternoon, if you have time I'll be around you're on my time. Well,.

B

I do that and we got any sometimes on. I believe right, yeah, so awesome. Let's make sure that happens and also.

A

B

So it pops up, there is the pups of the implementation floating that we are doing, and there is the pub sub test at that cabin is working. um Kevin wanna give us a bit well.

C

Then yeah, so the test net I'll put the repo into the etherpad here, but it's been making progress so basically right now you have the ability to spin up a test net of size n and you can pass it different topologies.

C

So that's kind of the basic line is like you've got network nice tan, shade a network of size and then give it a topology and it'll build this thing out so this week um it was a little slammed last week, but this week my goal is to implement three or four more basic pathologies.

C

You can choose from anybody else can add topologies that they want it's a pretty simple interface and then from there get some example docks up this week and also then I was talking with Herman about docker and containers, but he was a little pressed last week too, so hopefully get to that either later this week or early next, but either way by the end of this week, we've kind of got the infrastructure that people kind of pull that work on it mm-hmm. But that's where we're at awesome.

B

So um yeah I need to check all the way you do. The topologies like, if you have examples on the Reaper right line, Lindy shoe like oh.

C

B

Yeah because, like probably actually like who I'm creating test for the pub sub accommodation, the floating one and like I'm, just like spawning notes as well and I connecting them and I, see any messages passing true but like if we can import the pub sub test net and then use those notes. Yeah that'd, be that's the flood pops up and I.

C

Accede to working and I guess how, with all your topologies do you want to? You want to circle up after this and figure out like how to how to kind of get that wired up, because that seems to make that makes a lot of sense. Yeah.

B

Yeah, okay sounds good, um yeah, okay, what what? Let's do that, um because, after all, like you already have like all of those thousands of loads Vince porn and throwing pops up on top and seeing a message passing through? um Do you have anything for monitoring like um like to see the flow like yeah? You you spawn the nodes, but like? Is that a way to see all messages are like traversing, a network? No.

C

I could like it. We can figure something out, though, right now it's got like it's got a memory like a memory profiler built in, so you can kind of watch how memories building up and being used. Mhmmm.

D

C

Like you can turn on and off logs and things like that, but that's kind of a next level. It can be added. That's.

B

It like it'll, be very cool. It's like an idea, but I could be very cool like if you guys like a pipe to like just exposes a web page with some III GS or something that I can see. The notes well now, they're connected haha yeah that'll, be pretty cool, a pretty cool demo and also pretty cool debugging tool cool alright. So let's get it done, um let's jump into waffle, um let's jump into awful, so I can share my screen again.

B

B

Well, actually, my screen, you see my whole screen or just my browser. Just out of curiosity, you can.

E

Select different windows right now, we're seeing your entire browser obey my time. Rosa awesome, cool.

B

Ok, so again you can again.

B

Same thing as Jessica fest, we have this backlog now, which is are the things that we don't really have an awesome for, just like things that we keep finding or the tree real number that we eventually will process and make a target to cheat them. If someone tells em, for example, you can see here. Francisco one of the Jessica's contributors is like checking. The railing railing is like a bush truck loads like connecting to know, does like a note, spawns and the multicast DNS discovery.

B

We got that working before, but then, when the multicast DNS mojo, a note was upgraded to respect the RFC kind of got some differences with the government, ation and I. Think Jeremy already got those things forest, and so it's just a question of like testing it out again like seen with it all works, so nicely cool.

B

You can see, like so I'm doing this quarter. Okis on these three milestones. Well, almost four! So there is not some one which is getting things like interop and a sec I.

B

Oh, it's pretty much there and there is muscle to which is the improved connectivity of go mouse on three, which is the website and muscle for which she is I, need to check again to remember the title, but I believe it is the getting them getting the wig p2p organization with all of the community stuff and all the guidelines and like pointing people to the specs and so on, like polishing all that. So it's a nice experience for someone with chicken little bit cool so mouse on one, and this was already handled.

B

So you know, like masculine issues, pretty much the thing that we already have discussed on just a PFS. It is I the ability to go out without the PID, integrating pink and what should what?

B

Okay, you are able to do that. No, you are able to do that. So Jeremy is like sharing that and you can't that's.

E

Not a thing you should: okay.

B

Let me color family, for you, like the thing that Jeremy's commenting here is a to be a way to dial to appear without knowing the PID beforehand. Now.

E

You have to have the correct, but.

B

Like the guy keep an eye on down it works now we have a test that some jessilee it works. That's why I was.

C

Looking up next.

B

Okay, so Victor, if you are listening, you might have less floor than you actually.

D

B

Let's show me the test um you telling to pacifica score de-spawn tests and, like he dials what to think without the PID and it cancels okay. Can we do this thing so that people yeah.

F

B

I get sore a source and then its form, and then there's like the one of those you can check a movie on all right. um You want to give a quick update on muffin to Delhi, like what you need to achieve some of these things. No.

E

Idea, what do you talk? The.

B

Improved connectivity things so I can open. If I change my tabs, you guys yeah, you, you probably can see. So I can go here.

B

Willie people are more on top of Jessica pheasant imputed here so whether like to see the romance seconds like someone, the interop, a mouse on to improve connectivity and I PFS, know there's a lot of discussions that you need to have in order to achieve these walls right yep. Do you think that we are still doing them? This quarter? No I, don't think we ever agreed in this quarter. uh Okay,.

E

So maybe we need to reduce I was never coming back. We should I had drums, maybe movies like to another number and before it yeah I, don't know how that ended up there and being assigned to this quarter without me, knowing about it.

D

B

Might have forgot, but that's definitely a lot of this question around these three. The last gathering, ok, nevermind and sorry for sorry ruined, for this was distracting. We'll definitely revisit this items. The mouse onto was about like being able to close connections, which is something that's not easy. You would who taught it like? The hard part was getting.

B

Connections then really closing is even harder cool, so mouse on three is the website which is going to another tomorrow morning, as like, the focus for this week is pops up and the website, and there is someone at habit, improve quick twenty percent speed. Do you want to bring it up real yeah.

G

That's why that's why I put it there yeah.

B

Like I'm asking you like to bring it up now, oh yeah.

G

B

Do you like to talk about it.

G

Okay, so um there are two things for this, so the first one is so yeah we have sec I yo in JavaScript and that's pretty cool. The other thing is the current crypto that we're doing in javas, jet javascript is slow, like I did some basic performance tests and eighty percent of all runtime, like of v8, was spent doing crypto of the whole program. So, like hmm that's, not super quick, so I want to improve that.

G

This is a long-term ish effort like in getting everything faster, but there's things that we should do that we can do soon and the first thing that we need to do that, for this is make all crypto interfaces async. So currently note Forge, as well as parts of the node.js script to libraries expose synchronous api's.

G

They do some blocking things when generating some things. This.

F

G

You use a constructor to generate things like RSA, a keys but web crypto, which we will want to use sooner the rather than later, because it's the fastest way to decrypter in the browser currently only exposes promised base asynchronous in faces for everything that.

F

G

We have to move all synchronous interfaces to async interfaces, even if it's just a fake, just calling a call back or each our new promise based on a synchronous interface. In the background for now to do this, we need to change some things, especially the way we use constructors at the moment for things like peering from prd and there's a this issue open.

G

This is like from a technical standpoint just moving. Those interface is simple: I just want to call it out and let people so lets us sink in and like tell me, if there's something super bad about it, just tell me there's something we need to tell sweet to consider so.

B

One thing that we can do to achieve that quickly then like going through all the refectory adventure, is because fear IDs can be created from like an egg bike, republica that's already exists or from a JSON object it as the public and apparently so it doesn't like to do any processing. You can actually do first, the creation and then creating the PID object that perhaps those too.

G

Yeah we can do that, so we can remove the ability of of generating new keys from the constructor and saying the constructor always needs to pee pad need not always need. We always need to pass the finished key to the constructor. We can do.

F

G

There is a catch here, so the catch is, if we want to so the web. Crypto API also has the concept of importing keys, which you have to do. If you want to use any sort of key, you have to import it. For example, honestly, if you do an H, Mac and use a secret, you have to import that secret as a key.

G

That's how the web crypto API works, so those interfaces are asynchronous as well meaning if we want to have the take a web, crypto API a key and import it into your purity that import call actually has to be asynchronous as well.

G

Making this a not perfect solution, because we we can get problems there again, because we don't want it. If we were using web crypto, we don't want to import the keys and then export them and then put them in a to appear at the end with we use them import them again, because that's overhead, we we will need to have a standard, key format and imprinted once put generated once and that import and generations that both of them will always be a synchronous like.

B

From what I understand like the reality is like definitely we take a lot of time on generating keys like it is one other thing that takes most time on pudding.

B

Tests and I was actually going to open, initiated a about what just like generate a bunch of keys before I, had it for tests and I, create them from this and I just tested him because generating RSA keys, even we reduce the decides it takes time, but but I guess like one of the things that really takes a lot of time during the whole, like it's not that etc. Is this like ciphering, encrypting and decrypting like the debt operation and that's all I generating key is in it definitely yeah.

B

That definitely requires a lot of lycra fracturing details so that we can it's.

G

Not that completely it's not that complicated to. Actually we don't use that made different crypto things inhale.

C

G

That this is like a huge bunch, massive amount of work. You know.

B

G

This is why I was saying like: let's get all the interfaces to be a sink and then.

F

Me and everything.

G

To use the PTP crypto and then I can go piece by piece. So, for example, I can then go- and this is like maybe a days of work like replacing inside the p2p crypto DRS, a generation with native things where available on node and the browser right. Oh.

B

How much time do what you need to do? The first step, which is migrating? The interface is decreasing. Somebody can I do in all today and get it done or it's.

G

Mostly a search and replace thing right so because we have many modules, it yeah, it's gonna, take a couple original.

B

Yeah and making sure like everything, is.

G

Not around so that that's the major thing in.

B

Terms of actual.

G

Work, it's not that much right. So what we could do here is I could put the main things so Pierre IDP reinf, oh and Deepika crypto and.

C

G

Could help me out, like just going through all the modules and okay.

B

Yeah that'll be great, so I guess the point I was trying to make is like if it's more than off today, not before the phone. um That's what I my point! Actually, if it takes you time from my getting beat swapped interop just leave it for after because.

G

Ya know so it's warm and drop I will do before right. So I will. I hope I really hope, unless I had something very but something very bad to get fit swab and drop happening tomorrow. If it takes me longer, it takes takes longer, but I will do that that, like my priority right, so no.

B

Actually yeah after the gut interop, we should use the pub sub testament, which is the I PFS PFS test and I guess, because it spawns a lot of loads to do big swab test as well like to to like make sure we don't like. We don't have memory leaks all over the place that, since our a Gavin, a documentary profiler and everything like to make sure that I beat swap is robust enough. So that people can like well Jessica Vess and not have the browser that, after five minutes, I.

G

Don't know how to do that, but I would love to welp.

B

It's funny a lot of notes and like creating files from one and like getting all the other nodes to time like requesting. Like imagine like you have a tree, and this one is creating blocks, and this one like once these walks and then like a little bit after you say: hey, you also want this blog tonight, ghassan just want and I.

B

Finally, when there is like a line why the box will start passing through he'll be the last one we will receive so by, like you see like this, one doesn't go crazy if this one doesn't send the box right away, because this one will notice in the blogs. After all, the other nodes have received, it works through it's kind of like pops up.

B

It's accessing 7 p-12 have a lot of similarities and because, like big flower moves with more like moves, more data, it's more intensive and we need to make sure that works well and that we detect like.

F

B

And crazy errors cool, so we are five minutes from a family that minutes left. Does anyone have any other questions issues things that they want to bring to the chat.

B

Again, checking on board the first milestone. Basically, it's like overlapping what we already reviewed on Jessica Vess, there's a lot of interdependencies there. That's why I like doesn't really matter like to go to all those issues again and mouse on tool will revisit mouse on tree? Is the website being a no tomorrow?

B

Well, some for is getting I clip you to Pierre with a nice like community repo and like pointing to our guidelines in in my affairs like 20 people to where they should have like make questions and discussions and so on, and those four milestones cone are basically our this quarter. Til October till mid-october.

B

Aren't they well then, let's say an awesome tool will not be no.

G

But what about I pili this.

B

Is lee peer-to-peer and appeared on me, but.

G

I really well touch much of it. No, not all well.

B

It look at the Pierre is on just defense. I meant just agree to be at once. Yeah.

G

I know I I'm just saying: do we not have to do any thing on the p2p man for making actually not.

B

Quite, for example, no we definitely like your book mending the seats cooling went a little bit because then the topic descriptors, which is at Pollock that describes, who is authorized to publish we'll ever see each other wise, just a multi ash, but like CD 0, is just 0 cash, so it can be invisible for loop.

B

It appear that if there is a seed or multi ash and then and then there is a question if we should rename the pure IDs to slash p2p year and I, have a seat instead of I camuti ash for the idea of the pier, which is something that we kind of like roll up several times and everyone said I had that make sense. But who was like really said: okay, like what's the best time to change that right now, because it changes all the PID s.

B

We still have to think about what that means in terms of migration. So ya might not death detail might not count. This quadrant accepts cool um all right, so Gavin you like to revisit or check the pub sub stuff after this call by vfm or connect if I'm um yeah. So, thank you, everyone. We are two minutes from lean on main. We are getting super efficient. Are you things? I see that matt has a very happy place in saying yes, see so yeah. Thank you have a fun week and let's keep chatting.

E

Thanks guys, thank.

C

B

Adios abide boy.
