Description

ESIP meetups, Peertunnel publishing, Nodetrust certificates, Hubot as a plugin, and native protocol handling in Firefox; all this week on the IPFS all hands call. 😎

A

All right, everyone welcome to the ipfs All Hands call for July 23rd 2018 starting off today looks like we have a light agenda with a lot of demos, which is something I'd love to see starting off. We should go with Michel for the summer report here.

B

Give me a thumbs up. If you can hear me I had phones are all aware it awesome. Thank you just a quick report out last week for most of the week, I was at the esup summer meeting ISA this earth science information partners I believe they pull together a bunch of earth science. Data managers like people from NOAA people from NASA great folks, I worked with them before when I used to work with NOAA I proposed an unconference session there and distributed web stuff. It was packed. People were really interested.

B

What they had heard about distributed web stuff was a bit of ipfs. A bit of DAT in general. Debt seem more approachable to folks I'll, be writing up notes about all this and I will post it in a public place. May yell no but yeah some interesting things there and lots of interest. Also now, on the ease of slack there's a distributed web channel where people are just kind of what is going on here. There is a future here. We don't know what it is, we're very excited.

B

So another thing is that if anybody has interests or time I can hook you up with where that slack is, it would be great to have people there to be able to answer questions, but that's a separate thing, I think that's the update, any questions. Anyone have questions.

B

Lovely I'll write up in more detail the full summary of all that, but I wanna. Let you know that happened.

A

Perfect, alright, so that covers the agenda. For today, moving on to demos looks like we have two from matcha here. So is he yep if you're ready to go through with those you can go ahead now.

C

Yeah so I built a tiny tour tool, basically just published something that's running on localhost behind HTTP and.

C

Wait a second so I have this web server running your localhost and now I just run it katana tool, which then connects to this lip PDP server and then opens a tunnel. When I now go to this page, it simply dies to peel back and opens a tiny relay, and now this page is published yeah as I said, and everybody can read it from internet. So anybody can visit this. Your end right now and also it looks access so.

C

It's basically it's this tiny tool and it uses little P. That's why I Demetria has anybody got any questions.

A

Rob, the other question.

D

Yeah, it looks like you didn't necessarily add any parameters or.

B

D

That because it tied to a particular host or peer ID or something.

B

D

Is that configurable like how do you run the other end, I.

C

Totally forgot to mention that there is an admin interface that allows to assign a user name per here ID and then that user name is being used as the host name, it's also possible to add the suffix. Maybe I could demo it. I forgot that so I can also, if I, want to add a suffix.

C

And then it opens starting under mpg 20001, slash website and.

C

Yemen interface, this also just simply.

C

Gives us add another ID and then I cannot I.

C

Think I forgot the API, so it's better not to them honest I didn't really use it too much after I made it, but that's basically what it does.

A

Any more questions.

A

Alright much if you would like to go on with your second time out, you can go ahead.

C

So the second demo is I have written this room called EPP, no trust some time ago that issues certificates to any note based on its IP address and I've recently, rewritten the whole thing in micro-services, so it can be managed more easily and wanted to demo how that works, and so this is the demo page. This basically connects to the issuing sir, but it also runs pops up where all no trust notes announce there are no trust addresses and connects to them.

C

So these are the addresses that have been issued and it connects to them and about the issuance process.

C

So here are four tires. The top left is the DNS heart. Top right is the proof server. The bottom left is the issuance ever and the bottom right is the server or the client run. So if I run, the client first connects with issued server then connects two different proof servers, for example, for ipv4, and then that should get long here. That would require two proof.

C

Then it does a DNS one charge while it's encrypt using a DNS server and then it acquires a SART via is me and since assert back to the client and after that the client should appear in the browser. Now it did and so much oh then fully work. Maybe let's reload the page.

C

And now it's connected to the client that I just launched yeah as I said by I'd, asserted just acquired and yeah. That's basically what no trust us and additionally I would maybe I don't know. If I should ask this in this meeting,.

E

C

I would also like to get this deployed and in the protocol. Let's infrastructure silent, have to manage this and maybe get it into J's ipfs because would be really useful for the browser, as browsers would be able to connect to any here instead of having to use PDP circuit because browsers have limited TCP connectivity and that everyone wants to run in jazz at the festival, web, RTC and yeah.

C

It's. What no trust us has anybody got questions today, I.

A

Would like to ask the group here if anyone with authority is present for for such a thing like we're, watch I go to to possibly get this into our infrastructure.

F

I could probably talk to Lars.

G

The actual can you give me.

C

G

The actual question is like do we? Do we actually need it like we? Thank you so much for demoing not dressed again matching. It is right now, just I can clear, because we haven't done the actual. Like thinking of all these fits together. We bleep utopia, collection modules and like what users expect is. Actually, we think are like really creates beauty issues in the future, and so there are all these questions like.

G

If we go maybe a couple months, maybe three months of ipfs our ends ago, will see that, like these questions were raised in the past, but like we still haven't, had the time to like dive deep and get an answer to those, and so yes, like I, guess like we couldn't just like post it like if it's just a question on like resources to like host the service and we can sit but from that to actually communicating to our users creating a tutorial about all these words like it's advising people to use it.

G

It's a it's a different step, and so I would like to see away with more people getting involved with no trust reviewing it. Like sharing, sharing their thoughts, probably like get no trust to be like to have a proper speken RFC, so other people can really understand what's happening underneath and I quote are the shortcomings that they try to solve. Otherwise, we we might just like keep adding something that we don't clearly understand the implications you.

G

Know I lost everyone, quick people hearing from to the end, I mean a very like a connection I'm. So sorry.

F

G

G

Yes, basically like we should have this discussion like any people are super interested like they should, or at least we can self appoint themselves right now or later, but like weren't here to review and work on this with magic in math. You can like follow up on the issue on fleek. It appear about no trust and defeating the group here to see if everyone.

E

Anyone as at the time.

G

I know that everyone is pretty busy with some events of that happening, so.

A

All right, so it looks like we have no other questions on that all right up. Next, we have Jamie with Hugh bot.

H

Alright y'all hear me: I am Jamie dialing in from New York longtime listener, first-time caller.

H

This will be a fast one.

H

So if you all saw a couple weeks ago, when Juan demoed, the ipfs, who bought scripted erode, which interfaces with the daemon locally and allows you to run all these commands and then he'd done it kind of how everybody bootstraps a little who about plugin, just as like a little script inside of the directly inside of your who bought application, all I did was just break it out into a plugin which I've done a bunch of times before for things that reused makes easier to upgrade it easier to publish easier to add into Europe who bought I sent in a little PR here on this tab before switching it over, which is still outstanding in case anybody wants to improve me and then, if you need a quick demo, I have a little who bought that I've had running inside of a couple different, slacks and IRC channels for a few years that, because you can see it's kind of just uses the external scripts, and so you got about IPS here, and this is published on NPM right now.

H

And then, if you want to see, you know, works exactly like the way ones did where you know. I can ask my help. I can ask FS help and then I'm gonna grab a hand, you could just save hash and weight and it pins your hashes for you and that's it. But that means that if we make updates to plugins centrally, you know it's as easy as a little NPM update inside of your own boo box to get the latest version, which just makes an easier thing to easier to maintain I think that's most option.

H

Obligatory awkward, any questions.

H

H

A

All right cool demo of a side, but let's move on to another cool demo from Lydell here talking about ipfs in firefox, nightly yeah.

I

hmm Let's try to lower my screen. Okay, let's read.

I

Can you see my screen yeah cool, alright, so I created a Lib D web branch in aquifers companion, our companion browser extension and you have to use scripts to build it. The sleepy web experiment, you just run lib, do a build and then you need to download Firefox nightly, make sure it's on your path and then, if you run in this context, you just start Firefox nightly with our little experiment, and hopefully yeah looks like it.

A

A

Lytle I think you've gone muted.

I

I think I've, muted myself, when I was like dragging this sorry about that. So we don't have many. We don't have many hashes to test so I. There's this issue with this experiment and I put some hashes. So if you copy a hash and put it in the address bar, it will load natively and it stays there. So what's happening behind the scenes. Is that there's no HTTP anymore, at least in the browser context? We are stringing corresponds from ipfs node right now.

I

It's like my local node, which I connect over HTTP, but you can switch to ember that one that will work at some point. What's cool about this? Is that not only images work but also like regular? Okay? Maybe if I don't make a typo yeah, if you copy without a typo, you will see there is like a regular website, loading from ipfs protocol and not only that we also have directory listening back again.

I

You can't reverse directory and you should have it locally. It goes much faster.

I

What's most exciting, for me is that we got a streaming working, and that means- and that means you have like a video of working over this negative protocol- and it's actually it's a real stream. You can start watching before it loads.

I

What does not work yet is that if you try to use ipfs protocol in things like video tag, I like created a small demo page- oh okay, not work.

I

So that was not supposed to work and I think there is some kind of a bug because it not always works. So there are two videos: one is like lovey-dovey ipfs protocol and another one is read from the public gateway.

I

That's the current state of things. We also have like basic Rohan link. So if you paste invalid CID, you will get an information that you should upgrade to base 42. It will make this like user experience better, but for now that starts- and there are like a list of open questions and known issues which will be talking over time with friends from Mozilla watts. That's the current status updates of a native protocol handler and I'll stop sharing right now, so I can see if there are any quick cuts.

I

And questions Rob.

D

Is is the supposed bug that we didn't get to see? Is that a Lib D web problem, or is that something on a companion side? That's.

I

A good question, I suspect the problem is that the way streaming of video sources work? This may be like internal hundred of our content range header in HTTP. The problem is that when you move away from HTTP, you don't have this abstraction, so it may be that we may need additional like metadata layer or like way of signaling ranges for those whose cases that's like an open question. It might look like it's possible that it started working because I've opened it directly before so it was like in Firefox memory.

I

It might be related to Firefox specific architecture. It might be specific to experiment or it's just, maybe that we don't have those like range semantics. Yet.

A

All right any more questions for that: okay, any impromptu agenda items or does anyone need help with anything that they would like to ask? The group.

A

Michelle I.

B

Have a question- and you might be able to redirect me somewhere the biggest question that came up, but he said well, maybe there are two separate questions. One of them was what happens on ipfs, for something like New, York Times, or something like that. Where there's a place that you want to go a lot but the stuff underneath the changes. Is that something that someone has written up or does that make sense like you might have a Content address to an article?

B

But you want to find a group of articles somewhere that, like folder, does there a concept of that and I give us.

B

Might not be a good question I'm reading some texts here.

F

If you go from the top again, you want a like some way to link from a content dress article to some set of articles.

B

Probably I mean the general concept that I couldn't explain, it cuz don't buy. Neither the key was that what happens then was something like the New York Times, where it changes, but you want to have you want to be able to put in it yeah? You could also think of it. I mean related, but maybe a separate question is like streaming, but that's kind of a separate one, but we.

F

Have somebody called IP NS, it's a.

B

J

F

System, so you can put your your data in a Content restful system and then make an IP NS point or point to it, and then we gonna update it. You just you change it and you could get a new content restful address and then you make the pointer point to the new thing.

F

If you want something more like live, you can do this with JavaScript, where, like you load some content, addressable thing and you're in your website in your web browser and then you're writing, JavaScript the background, the connection, various servers or like text to like the lipid EP network and you just publish something like that's like touch new data, but it really depends on what you're trying to do for like a simple like you want to make the New York Times or you want like make some blog, you gotta for yourself or the content.

F

Users use IP, NS I.

B

Think that was their their way. Their example, probably about the use case for big data stuff, would be a new version of data comes up and you want to be able to like say: oh here's all the stuff and then okay, here's the new thing, there's anything here, there's new thing but not lose the connection, but this is the new version of the thing. A lot: okay, yeah.

F

Usually, what you do there is you you would like, you would have your data set you'd have a high penis link to the points your data set and you make the I've been a twenty point. As new data set and the new days. That would point back to the old data set.

B

I'll learn about IP Ness sounds like Larry. Thank you. Oh, that was Johnny sang a thing.

J

Built on that with the web, companion and ipfs colon slash, slash is that is the IP NS colon slash, slash and ultimately, that's going to be a hash of a public key and in base thirty-two encoding how to handle the multi keys, especially for elliptic curve, public keys. You know what was the challenges to to that I suppose the question is really for Lydell yeah.

I

So that's a very timely question because, like right now, if you have IP NS- and you want to refer to the to appear- use like your ID right and the problem is that those are in base 58 and I. Don't think we have like a convention or do we even allow different like at least multi base and coding yeah of tier IDs. So that's like an open question and until that solved we won't be able to use IP NS in your protocols on the IPS.

J

Okay, do you have a documented issue somewhere so I'm working on this right now with as I presented last week? Was this IP ID project with Edie two five, five, one, nine and there's emerging standard for HD wallets using two five, five, one, nine and so I think, but it ultimately since using the peer ID has. This did unique identifier, its I'm writing to this issue about base 32 encoding and it suddenly, like not gonna, be possible. Yeah.

I

Like like, personally the way I see it, the current PRP ID is just like multi gosh. So if we allow to put it in CID one like representation, that would work the same way in ipfs and in IP and s it may be that I don't see some technical problems. Stephen yeah.

F

So, at the end of the day, we would like to switch to IP LD forties telugu, rid of all those issues, but the upgrade package is a bit unclear because, like the key version, 0 the CID version, 0 of keys, is not the same thing as a CID version, 0 files. So we.

B

F

Things that, like their bolsters, bare multi hashes and can't tell the difference. There are some issues that try to figure this out, mostly by saying well, there's no real CID version, 0, it's just contextual, based on the prefix feel like you know it / IP, FS /, the ad version. 0, you interpret it one way. If you have our sessions, they're hash interpret it one way. If you have / p2p, fair hashers, new tradition boy. Unfortunately, we also have like we've been using / ipfs for the protocol as well vertical name.

F

So we can't quite big you like that for like currently like, if you have /f size, that's less to them, whatever. That could either be a file or a key, and you can't tell it at the moment so.

D

A

D

I'm, the more practical side does that mean for with the web and companion stuff? The only way for now to address mutable content that reliably works is DNS link, so you could have a DNS Collins life life domain name.

I

Yeah, like anything apart from the native protocol, will work because, unless you want to put a PID like the key hash in sub-domain and I, think a part of using that in subdomain will work perfectly like it works right now. Subdomains and native protocol handler are kinda the same abstraction you put base 32 case-insensitive.

I

Hash in authority component and the thing else will work. Fine does.

F

This do vertical handler have a link limit in the.

H

F

Now sorry, this video protocol handlers, video I've best protocol and don't have a link limit next.

I

Lamp, how long can it yeah I don't think we did not try that okay.

F

Hopefully not we got like right now. We have everything, sort of fits in a debate name in the future. That's probably not gonna happen, so that will change over time.

A

All right, we are slightly over time, so I don't think we have any more time for questions, but it seems like a productive session with that said, I think that's going to conclude our meeting for today. So I look forward to seeing everyone next week take care, bye, bye,.
