WEBVTT 00:00.000 --> 00:14.080 Next up, we have James Smith from the Manifold Project. 00:14.080 --> 00:26.080 Hello, it's just, yeah, it's like, I don't envy whoever has to follow the previous 00:26.080 --> 00:28.080 talk that was amazing. 00:28.080 --> 00:35.080 I'm James, and I'm going to talk about a thing that I'm building called Manifold, or many 00:35.080 --> 00:40.080 fold, or nobody knows quite how to pronounce it, just. 00:40.080 --> 00:41.080 What is it? 00:41.080 --> 00:49.080 It is an application I've been building for about four years that is about organising 00:49.080 --> 00:50.080 3D print models. 00:50.080 --> 00:57.080 So I've got a 3D printer, I've got a huge pile of model files sitting in a folder somewhere, 00:57.080 --> 00:59.080 and I don't know what they are. 00:59.080 --> 01:04.080 So I built the thing, the lights, he browse them, preview them, organise them, tidy them up, 01:04.080 --> 01:08.080 rename them, tag them, all that good stuff, troubleshoot them, convert them. 01:08.080 --> 01:10.080 And it renders them in the browser. 01:10.080 --> 01:13.080 These are all, you can subtly tell that there are different angles. 01:13.080 --> 01:18.080 All of those will move in the browser, you can view it live. 01:18.080 --> 01:19.080 So that's cool. 01:19.080 --> 01:21.080 That's the thing I've been building. 01:21.080 --> 01:26.080 It's a bit like having your own thing of us, but without the horrible download for 01:26.080 --> 01:32.080 the second advert banner, which on my home network, the ads block. 01:32.080 --> 01:35.080 So it's just a blank screen, it's just annoying. 01:35.080 --> 01:36.080 We don't want that. 01:36.080 --> 01:39.080 Instead, it's self-hosted container. 01:39.080 --> 01:40.080 It's a Docker container. 01:40.080 --> 01:45.080 It's built in Ruby on Rails. 01:45.080 --> 01:50.080 And you can install it in a bunch of different places, but you just run up a Docker container. 01:50.080 --> 01:52.080 And you can run it in a bunch of different modes. 01:52.080 --> 01:56.080 You can run it as a private single user thing, just for yourself. 01:56.080 --> 01:59.080 Just to look after the files that you have. 01:59.080 --> 02:03.080 But then you can also put it in multi user mode, share things with your friends. 02:03.080 --> 02:06.080 If you want legally allowed to do so. 02:06.080 --> 02:09.080 Of course. 02:09.080 --> 02:11.080 And then it can be federated. 02:11.080 --> 02:13.080 And that's what I'm going to talk a little bit about. 02:13.080 --> 02:17.080 Now, it's about how I'm doing that. 02:17.080 --> 02:20.080 How I've made up how I'm doing that. 02:20.080 --> 02:24.080 And this is like a big feedback session where I want you to tell me whether what 02:24.080 --> 02:27.080 I've done is terrible or completely wrong. 02:27.080 --> 02:31.080 But actually, hearing the talk so far, I think I'm not too far off. 02:31.080 --> 02:34.080 So there's a write up. 02:34.080 --> 02:36.080 There's a description of it on the website. 02:36.080 --> 02:38.080 I'm about to release this. 02:38.080 --> 02:41.080 It'll probably come out next week. 02:41.080 --> 02:44.080 I didn't quite get it done in time for foster. 02:44.080 --> 02:49.080 So the first thing that I need to do is have a few extra properties. 02:49.080 --> 02:57.080 So I've defined a name space, which I realize I've also given an unpronounceable name. 02:58.080 --> 03:01.080 So I'm no kidding at naming. 03:01.080 --> 03:06.080 But it was things that I needed to be able to express in activity public without. 03:06.080 --> 03:11.080 And anyone who's done massive on interoperability knows about two namespace and things like that. 03:11.080 --> 03:13.080 So it just adds a couple of bits. 03:13.080 --> 03:15.080 I'll explain what they are. 03:15.080 --> 03:17.080 We have a bunch of actors. 03:17.080 --> 03:20.080 Much like the other platform to talk about. 03:20.080 --> 03:25.080 There are actors aren't necessarily just people there. 03:25.080 --> 03:27.080 I want to follow a particular content creator. 03:27.080 --> 03:29.080 And that could be a bunch of people. 03:29.080 --> 03:31.080 But there's a profile for that. 03:31.080 --> 03:33.080 I want to follow a particular model. 03:33.080 --> 03:36.080 I don't care about what the rest of what this person's made. 03:36.080 --> 03:38.080 I just want to know if that one changes. 03:38.080 --> 03:40.080 Can you feed back? 03:40.080 --> 03:42.080 No. 03:42.080 --> 03:45.080 I just have a metal neck. 03:45.080 --> 03:47.080 I don't know. 03:47.080 --> 03:50.080 Or I want to subscribe to a collection. 03:50.080 --> 03:54.080 So all those things anything that you would want to follow is 03:54.080 --> 03:56.080 an actor. 03:56.080 --> 03:58.080 The actual login users are also actors. 03:58.080 --> 04:02.080 They don't create them quite the same way. 04:02.080 --> 04:11.080 And because of the well-stated issue that interoperability with masters on requires certain 04:11.080 --> 04:13.080 sorts of actors are ignored. 04:13.080 --> 04:17.080 It would be great if these were if a 3D model was a 3D model. 04:17.080 --> 04:20.080 Object that actors are acting. 04:20.080 --> 04:22.080 But that will be ignored by lots of things. 04:22.080 --> 04:26.080 So we use some of the standard types. 04:26.080 --> 04:30.080 And the standard types of that mastered on the stands. 04:30.080 --> 04:35.080 And the first little bit of extra data that we put in there is this concrete type, 04:35.080 --> 04:39.080 which actually when that activity public message comes to another manifold instance, 04:39.080 --> 04:41.080 it can go, ah, now I know what that is. 04:41.080 --> 04:43.080 It's not just a person. 04:43.080 --> 04:46.080 It's a content creator. 04:47.080 --> 04:51.080 Um, we support a whole bunch of activities. 04:51.080 --> 04:52.080 Uh, on those things. 04:52.080 --> 04:54.080 Models dressed in collections. 04:54.080 --> 04:56.080 You can, you've got bidirectional federation between 04:56.080 --> 04:58.080 uh, manifold instances. 04:58.080 --> 05:02.080 Um, they can, you can follow any of them, etc. 05:02.080 --> 05:07.080 Uh, users, you don't really, you wouldn't really follow a user on a manifold instance. 05:07.080 --> 05:10.080 Yet, I haven't worked out whether that's useful or not. 05:10.080 --> 05:12.080 So it's not what I'm currently doing it. 05:12.080 --> 05:15.080 Um, but the other thing they will see is notes. 05:15.080 --> 05:17.080 Because, um, yeah, sorry. 05:17.080 --> 05:21.080 So this will mean nothing to you. 05:21.080 --> 05:26.080 But that there, if you follow, uh, create it on another manifold server, 05:26.080 --> 05:29.080 it will pop up in your list of creators on your server, 05:29.080 --> 05:33.080 just like a profile would do on, uh, on master. 05:33.080 --> 05:38.080 Uh, and the only way you can tell that is that it's got the address there. 05:38.080 --> 05:43.080 But anyway, live demos are not a thing. 05:43.080 --> 05:48.080 So, um, right. 05:48.080 --> 05:51.080 So all these actors are getting updated. 05:51.080 --> 05:53.080 So creator releases a new model. 05:53.080 --> 05:59.080 They will, but it will send out an activity for, yes, a new model has been created by its person. 05:59.080 --> 06:01.080 So it's a new actor creation. 06:01.080 --> 06:04.080 But that doesn't really work in the micro block world. 06:04.080 --> 06:09.080 So what I'm doing is also sending out a note at the same time 06:09.080 --> 06:11.080 to the same set of followers to say, 06:11.080 --> 06:14.080 which is a better text description of, 06:14.080 --> 06:16.080 hey, look, I just published a new thing. 06:16.080 --> 06:19.080 Literally saying the same thing, but in a note form. 06:19.080 --> 06:24.080 And the other, uh, a little bit of extra metadata is that I'm calling this 06:24.080 --> 06:26.080 for my own purposes a compatibility note, 06:26.080 --> 06:28.080 so that when I do build commenting in, 06:28.080 --> 06:32.080 and we can get replies back, I can just ignore it. 06:32.080 --> 06:34.080 That's one of them. 06:34.080 --> 06:39.080 I think that was the first one that probably worked back in October. 06:39.080 --> 06:45.080 Uh, so that's a Macedon account following a creator on a manful instance. 06:45.080 --> 06:51.080 Um, now all this is, I was saying this is Ruby on Rails. 06:51.080 --> 06:55.080 Uh, and all of the activity pub core of all of that, 06:55.080 --> 06:59.080 there's the manifold code and then the core of it is in this thing called Federals. 06:59.080 --> 07:02.080 Uh, which I didn't start though I've done a bunch of work on. 07:02.080 --> 07:04.080 Uh, as part of this. 07:04.080 --> 07:08.080 Um, and it is a Rails engine for activity pub. 07:08.080 --> 07:11.080 So you can add the gem. 07:11.080 --> 07:13.080 Uh, you can mount the engine. 07:13.080 --> 07:16.080 Say, right, okay, I have Federation here now. 07:16.080 --> 07:17.080 Uh, set, do some flat up. 07:17.080 --> 07:21.080 And then you can map it to the objects that are in your application. 07:21.080 --> 07:26.080 So, uh, this is my use of model in my normal application. 07:26.080 --> 07:29.080 Um, and I can just say, oh, and this is a Federals actor. 07:29.080 --> 07:31.080 And there's a bit of configuration. 07:31.080 --> 07:37.080 Uh, it can react to following Federals handles all of that stuff underneath. 07:37.080 --> 07:43.080 Um, and, uh, you can create activities and so on. 07:43.080 --> 07:46.080 And all of that is sort of handled, uh, lower down. 07:46.080 --> 07:48.080 You can also have data entities that are just objects. 07:48.080 --> 07:52.080 Things that no have to turn themselves into objects. 07:52.080 --> 08:00.080 Uh, and we've also, uh, as part of this produced a add-on gem for, uh, moderation. 08:00.080 --> 08:04.080 Uh, because before I did any activity pub stuff, 08:04.080 --> 08:06.080 I wanted to be able to block it. 08:06.080 --> 08:08.080 I'm a master on admin as well. 08:08.080 --> 08:11.080 I know this and things that I want to block straight away. 08:11.080 --> 08:15.080 So, uh, so we've got to put in there for flag activities to main blocks. 08:15.080 --> 08:16.080 Uh, stuff already. 08:16.080 --> 08:20.080 And all of those, all that gems you can just, if you're building in Riga and Rails, 08:20.080 --> 08:22.080 you can just go pop it in. 08:22.080 --> 08:24.080 And hopefully fairly quickly, you should have, 08:24.080 --> 08:26.080 Rails out, but Fed writes. 08:26.080 --> 08:28.080 And that's my time. 08:28.080 --> 08:29.080 Take care of that. 08:29.080 --> 08:30.080 Take care of that. 08:30.080 --> 08:31.080 Thank you. 08:31.080 --> 08:36.080 Thank you.
