From YouTube: FRIDAY FUN! HTM Chat, AI Chat, live coding in javascript, neuroscience chat, twitch API webhook subs

Description

For most of this video I was trying to get some Twitch overlay features working. I investigated the Twitch API docs for streams and users, and tried to set up webhook subscriptions. -- Watch live at https://www.twitch.tv/rhyolight_

A

I need to make like a checklist of things, to do every time. I start a live stream, because I feel like I, should tell people somehow what's happening and that's one of the reasons I bought one of those board things. Okay, I want to fig there's something wrong with this overlay, because it's I can't see the bottom of it. So I'll just bring this over. So you can see what him get away. Yeah I got to do left space here.

A

It's the same way over there, so that I should be able to there's a bottom to this and I, obviously don't have it I thought it was see the bottom there it's the wrong stream, but I. If I want to get this fixed before I go on because I want the stream thing to work, it should be cool.

B

A

So where was I I'm going to adjust this thing.

B

A

Index should pop it right here.

A

A

Sorry I'm distracted because my wife is chatting wish me- that's okay, nobody's watching anyway.

A

A

All right so see where it says: Greater, Pittsburgh, regional, that's coming from a alive I guess get rid of this now. So now we're just looking at this part. This is local, and this is coming from a different stream channel, which I could change it now to mine. So it'll do that I.

A

Worked on this a little bit yesterday, it's in that HTML, though I'm doing this. Now that I have a stream should be able to refresh, and if it's not getting it, it's not getting moisture. Oh yeah, there's there. It is so now here's my my chat, title I've been streaming for three minutes: I have one viewer viewers, one viewers, oh and that's up in the corner too, so eventually I'll get rid of the thing in the corner.

A

So this is not making any webhook calls it's just when the server comes up it it's it hits my stream and asks if there's anything, live and shows it, but it's better than nothing. I, don't think I'm going to set up the web hooks today, I'm gonna go answer some forum, questions and stuff and I'm gonna figure out like when I start a twitch stream who do I need like what are we? How do I need to I need to make a list of like I want to post it and discord on new twitch?

A

What am I writing in this? When I have.

B

B

A

So, like new stream checklist I, don't want to tweet about everything, but I will maybe disk or discord. I'll probably make an HTM forum link cuz I want to try and get people from HTM forum to come on here and another way. I've done it. Oh yeah I see the things I put up here.

A

Maybe in other discord channels, I've got our other servers. I have the HTM I think I called it HTM chat, which just link down there.

A

Anyway, so I should probably at least an ounce and discord that I'm live and I'll open up the voice, chat, yeah, so live and voice chat is open. So if anybody wants to jump in from discord, I see a few people online.

A

You can do that. I need to turn the volume down in my office a little bit.

A

And one thing I have not figured out, which is a real bummer, is how to get my desktop audio from my Mac streamed into OBS, because I need that I will definitely need that I know you have sound flower I've already got that installed, but it seems like I can either stream it through desktop audio in OBS through sound flower or hear it I can't do both you can't so I, don't know what the fix is there, but anyway, so I'm gonna fix this. This Roku overlay real, quick once I get back over here.

A

So this is too low and it just needs to be moved up. That's all and I think I just used the wrong CSS on it. I think cuz I put a header and a footer and I just split one I put one, you know: I know the margin where it should be I just put it too far down. So, let's, let's try this 10:30, let's search in 30 pixels for margin top and then unfortunately, I'm gonna I think have to like redeploy and test it out and in OBS, which is you know over here.

A

So, first off, where was that a footer margin top I'm, changing it moving it a bit, and so that should be reflected here it locally. It moves a little right. 10:30 I think is where it ended up, but now I have to actually deploy it to I. Have a lot of windows open, not sure why I don't need this one open! I! Don't need this one open! Let's just use one! Let's just use one shell, okay, they're bad with that. Okay,.

A

B

It adds static.

A

Get commit, moved, Twitter, get push, origin get push, Heroku Master, that should redeploy, and we should see it updated here hopefully, and it will hopefully move a little once once this moves a little still deploying then we'll put it in the right place in OBS hello to viewers by the way I fix chat so it'll pop up in the right place.

A

If you chat, I I'm I am going I'm trying to fix my little twitch overly here and then I'm going to go into HTM forum and read some forum posts and respond forum posts and then I will probably work on maybe HTM path, Marty's project or talk about the object recognition, although I think I'll work on Marty's project, ok, so there there we go, it take always takes a while for the first first load turn the gain up on this by the way.

A

Alright, that's not the right. Okay, hopefully that's not too loud. This is my connections. Kind of bad. My voice connection looks like it's bad sorry.

A

Somebody in chat was telling me they're just leaving for work. Bad timing, I know okay, so this worked. So, let's see, if it, if it it should refresh I hope I might need to might need to move it so I'm here, oh front, for example, I was hoping it would.

A

Rilla, oh I, see: why did it do that? It keeps changing sizes which I don't understand. Oh wow, that's new! That was new, okay, I'm gonna. Take it off completely I'm gonna. Add it back browser source, oh I'm, not even looking at the right one hold.

B

A

Let you see what I'm doing I'm gonna add it see what what happened here. This is what happened last time, interesting, okay, so I'm taking off the Heroku overlay, I'm, going to add it back and I'm hoping it'll size properly.

A

The Heroku overlay is just a server version. Why did it sighs so bad, and why does it turn white like that now everything's completely white? So just while it was loading, that's interesting!

A

This OBS! This got a really bad bug on Mac I see it's not even it's totally not sized properly, so I need to figure this out because I want it to look like this, and it's not looking like that at all. It's it's halfway over not all the way over I mean the easy fixes just to keep moving that footer up, which I guess is the easy thing to do.

A

But I want to I want my math to work out because I expected like, for example, in my settings, video output, it's 12, it's not 1920 by 1080! Oh, that's why I was it was 1,200, not 1080, so this this is easy, then so I should. That's! No wonder my math wasn't working I, wonder I'm gonna move this out, so you can see what I'm doing now. No wonder my math wasn't working. This needs to go on top there. This doesn't look the best right now in the stream, but I'm gonna fix it.

A

So you can see the bottom part of it soon. So if it was 1080, that's what I said right. The size of the footer bar, which is 55, should be anyway. Oh see here's the overlay, I put 1200, it's 1080, ok and let's put the black border back on so I can see it locally.

A

It's not running anymore, run, run it there guys and Oh see. Why is it down there so now I need to obviously I've got it in the wrong place.

A

So it's 1920, 55 or whatever I made it I know, don't tell me about less and see watch. This is how good I am at math, 1920, 55 1865, so margin-top, it's gonna be 1860, that's all right with height height height, not not with a 1080 55 courses, 1025, pixels and I want to keep the top border on it. Okay, so oh I, don't understand why it's there I, don't really understand why it's there and not I'm gonna cheat I'm gonna see if I can load. I'm gonna get rid of this here.

A

Yes, let's see if I can load the local one. I did this once and it worked local overlay test. It should oh, that's old, old old that doesn't work at all. That should actually can't.

B

A

Put this server can I put localhost, it's not a local file. It's it's localhost again I'm working over here I'm in OBS I'm trying to try to put the right overlay in place here and it needs to be 1920 by 1080. Okay, all right does it fit. It fits, but there's no bottom to it, because it doesn't because right now, 1080p is the only option yeah, it seems like it, but I, but I'm, just gonna scoot it up.

A

This is silly I'll, just scoot it up and not worry about understanding why it works, let's just spot. Let's just try 970 and see where that puts it. That's probably gonna be a little bit higher. Let's try, 950, okay and let's see what that looks like it should reload when I switched back and forth, but it doesn't and it totally changes size that bugs me so much. Why does it do that? It's again, it's a bug. I know it's a bug. It bugs me the bug bugs me for sure, and it's not showing up.

A

So let's kill it, yes bring it back. It doesn't reload local overlay all right and it's the wrong size. Oh did I I didn't size it right. Let me change the did.

B

A

Okay, there, okay and it's working, but it's but I, need to move it down a little bit. I can do that all right back to it where it was I, guess so, I'm gonna take those borders out shouldn't I should not that border I like the the barbed the Overland border, so shouldn't actually even see it should just be a bar on top and a bar on bottom. The thing is I think I have to remove it and put it back to get it to come up.

A

This is just a local one. It's not I haven't deployed it yet, okay. Why? So, if I open the configuration and then hit okay, it resizes, but that's good, that that works right. That looks pretty good. So I should be able to put this on the front too, and this is just a local overlay and it's hidden. Why is it so big I? Don't know that either if I hit okay, it'll resize, but it's not the right size. Still, okay, I'm deploying this and I'm gonna.

A

Remove the local overlays and I'm gonna only use the Heroku overlay. So, let's deploy it.

B

Static again, get come in.

A

B

A

Git push origin or keymaster.

A

Once I get this done and it looks decent I will get on with some real work. I guess you could call this real work, but alright here is the server it is restarting and then I will want to go so I've already got the Heroku over. Let all these places and it's already sized all wacky, so I'll, just good. It's working, ok, a browser and I understand this is not gonna work that I do the settings right. So it's 1080 or.

A

White again doing things live: everything's white, hey, hey! Hey! Hey! Hey! Look at that! This is good. This one just worked this one also works for a left screen share. I! Don't have that on so I just need to add it browser source or if you overlay.

A

Just confirm the sizing it disappears, it turns white and then.

C

Everything comes back.

A

A

Hello, there we go and it works. Ok, awesome same turntable, work, spirit, back works, ok,.

B

A

How about that people? How about that I did something with the twitch API, so you can you can see this I actually did make this open source. If you want to. If you want to look at it, I'll throw it in chat. I gotta get the chat open though, and it's just like a little node server and it I think it has my client ID in it. But who cares right because it doesn't have the secret so there it isn't chat.

A

So you can see if you want to see the code, but it's just a simple little I have not read. This is not great code. By the way it's just. It's I have not like refactored it. I can take off the twitch Watchers now, which is cool some of I'm back I'm, just love noticing an OBS, and all of these I can there's a that Watchers icon, because now I have three viewers right here. So I can just remove it.

A

Yes, although I don't have the twitch symbol anymore, that's, okay, and here it's also like it's already gone turntable. Has it so twitch Watchers remove I've been listening? The same Grateful Dead album for too long haven't I twitch Watchers here I will also remove.

A

Let's take let's, let's remedy this situation, anybody have any suggestions of what we should be listening to. Otherwise I will choose.

A

I have more Grateful Dead to you know a lot of Grateful Dead live stuff, hard soft jazzy. How about Pink Floyd? How about how.

C

A

About we go classic Dark Side of the Moon. You really cannot lose with this with this disk. This is one.

C

A

Not the greatest albums of all time, you can't go wrong with it.

A

Yeah I picked it on Spotify, but then you won't get this really vintage experience.

A

It starts with the clocks, I've I've listened this album, probably thousands of times you all should. If you haven't okay, oh man something's around my chat, so my chat is popping. My chat needs to be over used to be moved a little lovin, my oh you like my Skynet. She shirt. Okay. Let me just I'm trying. Let me just adjust my chat screen. They're, probably gonna have to do the same thing on all these. Just move them up, I'm, just moving them up a little bit.

A

You can see what I'm doing right here it just it was down there now that needed to be up there and then on this screen. The same thing. You can't see me doing this, but I'm moving it up. Okay, turntables the same BRB chat was the same just a case. There we go.

A

Alright, everything seems to be fixed. Hopefully so I'll do one more tests chat here.

A

Think I could shut all these down. I'm still sharing my left screen. Pissed chat pop-up there when oh there, it is Wi-Fi name- is Skynet network mode. I've seen Wi-Fi chant Wi-Fi called Skynet before.

A

And also seeing them called NSA, you know.

A

Okay, now, I can figure out what I was really gonna. Do whoops I'm on the wrong screen, so now I have to figure out what I was gonna. Do.

A

So perhaps it was oh yeah I'm gonna go over the form. I'm gonna answer form questions so we'll share this screen, just pop it through I, usually just go to latest then I. Do this every morning, pretty much on the weekends. Sometimes I won't I'll. Always look I always have to look and see what new comments or whatever have popped up, but I won't always every like Saturday or Sunday read through everything, because I just you know, you need a break.

A

Some I don't always want to be on with the community, but but every weekday I certainly will go at least once a day go through all of the all of the new messages and read up and and sometimes I'll just peruse them and think I know what that is saying, but yeah hi, Mark Brown the constructed location signal much of HTM 30 requires that a sense pattern is at some location in space, depending on which limit to pay for your reading. There's considerable variation, specific details in some of the papers.

A

It just is yeah, so the earlier papers were just we're. Just assuming there is a location signal. You know there's like the didn't specifically like the distal input to a certain layer of Cortex's. It contains location, semantics and so he's saying offer this thread to attempt to fill the details.

A

As far as splitting out you go, Alice enter coding, see this as representations at different cortex, Maps yeah. I, really don't know how that works. I, don't understand how that how the transition between ego and allocentric works, I think I've heard Jeff say that this could potentially be happening in visual cortex, where there are additional layers in l4.

A

Okay, that's five I, that's not from me, but I've heard Jeff said that he thinks that perhaps the additional or the larger l4 is some type of pathway to translate, because you have to have a place to do that: translation right to in to place allocentric objects into egocentric space, or else we wouldn't be able to model objects in egocentric space. So it's probably happy it's gotta be happening in some place in the brain, but that's all I know about it.

A

I said maybe I should comment on that, because I have a comment on this I. Just read it and commented on twitch, so yeah I guess I should contribute my thoughts to this. So I have heard and I'm gonna I'm gonna actually bring.

A

Jeff into this conversation right, that's you Jeff, Hawkins, I've, heard Jeff say that the extra layer and l4 within visual, cortex and I think this is v1 specifically but v1 I think it's a v1 might be a place where this translation from one from let's say this: let's say you go to a low centric. You go it's more like a low.

A

Let's just put a low ego. Translation is occurring.

A

That's all I know about it, I mean so that's all I'm gonna say I guess maybe Jeff will add something and maybe I shouldn't move this into no.

B

No I'll just leave.

A

It we'll see what see if Jeff has anything to say about that he's been taking a bit more he's paying a bit more tape. He's really excited about twitch by the way Jeff is we just talked about it this morning?

A

I think he gets it. I explained twitch to him and there's much you know bigger, as I could and I think he understands. I think he's excited like I'm excited, so that's good, cuz I'm very excited about twitch right now. This is the SDR class and the community fork stories, both sparse and dense formats, until either of them are assigned to when either the formats are assigned at other formats are invalidated. Recalculated. That makes sense.

B

A

Makes sense back to the latest HTM or spiking neural network? It's just a thanks for the reply.

A

A

How boosting changes the ESPY representation.

A

It's anybody. Anyone in this course voice.

A

So hey Bev, Wonder, Bread I, wonder if you will ever get on to twitch.

A

And one column is the representation of a change of a boost factor in one column, over iterations I. Think so, like goose factors, change I think we adjust boot. We can adjust boost factors as frequently as you want to, but it takes some calculation so in in in practice, it seems like you can get away with adjusting the boost factors initially for some initial time period and then once they've sort of established, oh boy, that's the clocks, once they've established what those are then sort of the pattern has been spread through the population of cells.

A

So I forgot to do the thing I said I was going to do, which was to tell the people in HTM forum that I am streaming. So that's something I'm going to do right now, I've been trying to figure out how to get people on HTM forum to comment to twitch I. Have this comp this this thread here where I basic? This was the first time this was more than two weeks ago and I. Basically, I made a twitch account over a year or two ago and I didn't get it I.

A

Just did it because I thought I had something to experiment with and I didn't do anything on it because I was I was working in Felton and there was this other guy in the office there was a co-working space and he he was a gamer and all he ever did in the office. I would come in the office early and usually like he would be there and I thought it was weird. Cuz I was always early. That.

D

Is a lot of clocks.

A

That's Pink Floyd.

A

D

B

In the office early.

A

And he would be there. I need either be gaming or sleeping on the floor, because I think he slept there, but.

C

D

A

Said he was, he was a twitch content creator like he gamed on Twitch. That was what he did, but I don't think it was very successful for him because he didn't last it very long and he also some on the floor. So that was my first exposure to twitch and I talked to him about it and I. Remember him being excited about it, but I didn't quite get it at the time and now I am getting it and so I sort of threw this out on the forum.

A

Thinking yeah I'm thrown I'm testing this out and just to see. If anybody would watch it and I think there's been a few people. Probably a bit Falco's on online there's been a few people that are consistently watching the streams which is great and like David, Keaney, sorry, Keaney yeah he's he's watched some his streams, Richard Crowder's watch some of streams and I know. Falco is usually on the streams. Tachyon was on the streams. Adonus has a a discourse server already and on his server I, just I found so there's already some involvement.

A

Oh also Marty here he's been watching the streams. Although some of these people have a hard time doing, it live because I'm doing it Pacific time and and everybody spread out, Marc Brown can't because you know work, firewalls, I hate that that's I hate that, but there's a lot of firewalls keeping this from being available for people.

A

You were just talking about blender, so at the end of this I basically said I'm gonna stop posting whenever I stream on Twitch and I'm gonna archive to the YouTube playlist, which I have been doing- and you can see here- this isn't even the latest stuff I, don't think I added, oh yeah! So here's the last these last two new pic Python 2 to 3 migration, I I stream, that on Tuesday I, think and then I did some live coding.

A

It's in this stuff for like three hours on I, don't even remember what maybe that was Tuesday! Well, that was yesterday anyway. I think I should probably I. Think I will continue to post that I'm live okay, I'm, just gonna keep posting that I'm live on Twitter, okay, oh I, changed my mind and I will we'll be posting on this thread. Every time I go, I live stream on Twitch.

B

A

Often so you, you know how to new threads if you need to okay. So that's a big threats. Muting a chat feature right. No, no! No, how I don't know mute topic new topic. You can mute topics there. We go just want to, let sure make sure people know they can.

B

Let's say mute this.

B

A

So anybody who's currently live, which I can I can see who's online.

A

We'll do it over here, there's an admin interface to Stack, Overflow and so I get to see more than you guys see. So I can see what users have recently been online I'm just wondering if anyone will be joining so we'll see. Let's go back to the list.

A

Is this Marquis annoying to anybody? I thought I could just make it smaller. If the thing what I wanted to do is as I change, what I'm doing in the stream I can go edit it and it will pop up. You know eventually, once I get the web hooks in place, which I don't I, don't have the web hooks in place yet, but ok, yes, I was nervous about that interview with Conrad nylon.

A

Recently, just listen this part to today. Oh I, really appreciated the amount of time spent discussing my question. It was a great conversation overall, great episode, thanks Jimmy I, honestly, don't remember what your question was Oh. Would you describe himself as a Bayesian in the context of AI yeah.

B

A

Talk a lot about that.

A

And this question to that was a good question: yeah cool community interaction for the win. What.

C

A

About here is where, where is the interview it's on our YouTube, which you can that's on HTM school? What I linked up at the top there? You can search YouTube for HTM school, but the video is here. If you want to see it since I'm referring to it and how do I put it in the chat. I'm gonna put it in the chat for anybody who wants to see it there popped.

A

Okay, I was really nervous about the interview. I, don't know, I felt very out of my element element because I have such just I. Don't have a big background in Bayesian statistics, I mean who does not really in this community a lot of people too.

A

This is one of those topics that I'm gonna come back and catch up on, because it's too much unless someone is mentioning me.

B

A

Maybe I should read this. Let me read this in contemplating the ramifications of an AI attempting to replicate its source code and improve on it. Most immediate question would be what computer language would the source could be rendered, and why is that.

D

A

First question: it doesn't make any sense. That would be my last question. Why does it matter what computer language it is I mean you might as well ask what language should we all be speaking as humans doesn't just pick one and use it right?

A

All computer languages eventually end up emitting machine code. If you look at the tasks of AI, understand the essence of what these constructions are attempting to do as compared to the general purpose. Computer language, I'm, left thinking that rendering and shine code source code is the wrong direction to be headed. If we move in the other direction, we could cleaner the realm of dsls, and that is where I think this project might get some legs.

A

So you think DSL. So you think the language is gonna matter. I'm, not sure the language is gonna matter. I really paul says my goal with this project isn't to invent some new process, that's better than humans at creating stronger AI. It isn't you and to attempt to make any useful product.

A

The goal is to demonstrate human-level. Ai is not a threshold for a system to be capable wait. The goal is to demonstrate that human level intelligence is not a threshold for a system to be capable of modifying its own source code to recursively. Regenerate, improved versions of itself is not a threshold for a system if you capable of modifying its on source code for Crusoe generators that are in turn able to do the same immeasurable, not better than the previous iteration human and just trying to process the words in the sentence.

A

It's not a threshold for a system to be capable of modifying its own source code for krisily right I'm, a little confused by that statement, but I'm going to skip it. What level of intelligence is there at evolution just to make just make eliminate any confusion about brains, apple, pear, same general, process of working evolution?

A

Fluid brings me uses it as a process and not guided by intelligence, I sort of agree with that I wouldn't call DNA intelligent, although some people do call T&A, intelligent I understand that Asperger goldblum, the coments orthogonals forints, whatever we're talking about it's going to have to render something I'm suggesting that a DSL would be more feasible, selective breeding of GM, oh yeah yeah. That sort of makes sense in that we are on an HTM form, and my original post of this topic was in fact my first post any topic on this form.

A

It would be fair to say that I did so with HTM on the brain now I get that we're not talking about HTM here but AI in general. That's from selective breeding point of view. Okay, I just wanted to make sure that everybody was so. This was vort reads: first, post I, think Eric before tree aid systems, architect for a major financial concern and working with grok a proof of concept for anomaly detection; ah very good, very good, okay. Okay, so we want to help the sky speaking figure from a selective breeding point of view.

A

It's time to flip the record, can you believe it it's already? No, not that one this one time to flip the record. The next side is money which is everybody's favorite, five, seven song.

A

Most people don't even realize it's an odd timing, because it's just done so amazingly well, just listen for it. It's five, seven I think there's at five o'clock.

A

B

A

Know five foot whatever it's like seven five beats.

A

One two: three, four, five, six, seven one, two, three, four, five, six, seven one, two three four seven beats per measure which is hard to do. It's really hard to do and it made it on the on the airwaves and they still play it on classic rock stations.

A

Don't want to create trees with source code, you still need an agent of change, are constraints. I am.

B

A

Yeah yeah, Paul's or Mark Brown brings up the cerebral code a lot.

A

A

Beyond all discussions between us from time to time, yes seems like there's a turn but I'm trying to build Auto constructive evolution. Interesting, not open, I like that term. Okay, you, young hookah! This is a I. Don't recognize you seen a day ago, posted a day ago joined so a long time ago.

A

So thinking my little comet was gone, probably because I'm, a frequent reader, but almost ever close. So are you familiar with the push GP language? So I think this is probably the hidden reply. Yeah this happens, sometimes whoops.

A

So let me I'm gonna I'm gonna go ahead and edit this just so it doesn't look. Oh they've got he's Paul's already done this. No problem, silently Experian across language, also be very good for you.

A

Gary could see back there's too much going on here. I can't I can't keep up with all this stuff holy cow, reciprocal causation. Oh I recognize this yeah Gary. This is part of your project. I recognize seen some of this stuff.

A

There we go. Okay, thought experiment consciousness and awareness move from creation, triad, which we haven't seen in a while welcome back software engineer literally 20 years, I hope I'm, not missing any chat, sometimes I feel like I'm I should pop this out. The second dashboard I can pop the chat room out like this.

A

Pull it over so I, don't miss anything I'm, not missing. I.

A

Want to get some feedback on a thought: experiment posted a video like to get some more rounded perspective, the human neuron, the gist of the experiment. You decide to model the human brain with your classmates in your neurology class. It just so happens. You have about a hundred billion classmates each one models: a single neuron. Each student is given a clipboard with multiple rules to follow under different visions, Alyssa preparing connections to other.

B

A

Mr. McPherson website signal so we're using humans to simulate neurons.

A

That's what orchestrates the experiment was this some it's anyone listening read the three-body problem, because this reminds me of the human CPU or the human computer that was in the three-body problem, making sure everything happens in time to a beat so that nothing gets out of sync. The professor also has a mechanism and translates the video input from a couple of cameras mounted inside a mechanical body into the thread, tugs and other sensory input. Devices there's also help with devices to translate thread.

A

Tugs in the movement question is granted that the speed of processing is slowed dramatically when a conscious mind emerged from this assembly and if the case is that it does, is it possible that people interacting in just normal communities at work or other such communal clusters also spawn some sort of distributed consciousness? This has me really thinking about a bunch of different possibilities with questions. Here's a link to a video I made if at all, you're interested thoughts, questions yeah, so I thought of the Chinese room a little bit too.

A

I, don't know the answer to that question. It may be our memes conscious, because memes certainly have a life of their own I. Don't know that they take actions. Do you have to take actions to be conscious? Probably maybe not. Consciousness is created through action and response and feedback, but you could take a conscious mind and cut off all stimulation and it would still be conscious, even though it can no longer take actions, it can still take actions in its own mind.

A

I, don't know it's it's it's a thought. Experiment, I'm, sort of interested in thought, experiments, but I think a lot of these a lot of it. It's just. Obviously it doesn't have a good answer yet and I don't want to think about things that don't feel like they have answers yet.

A

Okay, running community fork on windows, I.

A

Have updated the software and downloaded the dependencies? Oh, you know what I realized that I have no idea. How many of you is I have right now, because this viewers thing is totally wrong.

A

So that's interesting, you know, I've got this thing right here. Where is it? Where is it twitch Watchers? Let's move it back up one and it.

B

Said three: four guy.

A

B

So that's obviously.

A

Something out of fix who's, my lose my one watcher one watcher the left. One also I'll just leave it, so it says three actually.

C

Mean the next thing I could do.

A

Is set up the webhook, maybe then it would automatically update.

A

Oh, you don't want to see me get is no longer needed for llamo Steve, DP, download hmm I. Don't know why you would have needed that manual override for air-gap computers, networks. Read me his change table packages. I have not looked at this. This work in a while github HTM.

B

Community new picked up CPP cccp new pic got cccp.

B

A

No, no, this one. This is the community fork of C++ library.

A

Goals accessible and C++ and Python implemented in C++ bindings into Python, hopefully they're working towards Python, 3 I think I need to open a window in here. It's new feature, some of the major differences support for Python 3 and python 2 7 only python 3 under windows. So there's your python 3 support. We're we're not going to upgrade new pick for python 3 support, I, don't think I'm gonna get this Watchers thing up, so I can see it. I wanna see how many I have zero.

B

B

It's not that exciting anyway,.

A

So I could just put I, could just lie and put like 400 viewers.

A

But I won't that's dishonest.

B

A

Alright I'm gonna take a break beside me. Open a window.

A

I, don't actually know how many watches I actually have here.

A

There, it is it's actually one-one watcher, thanks for waiting, I'll be right there, but right there. So the one of the issues I'm having here is like this watch. This viewer is sitting down at the bottom. Here is not updating this. This also is not updating like if I go change, my stream, you won't, it won't update and I haven't been streaming. 18 minutes, I've been streaming a lot longer, so what I need to do is update the web server. That is currently running this thing, which is a node.js server, so I think I'll change.

A

First of all, maybe I'll change my scream description, scram or scream extreme description, and, let's say let's say.

B

Twitch API webhook.

A

Subscriptions web subscriptions node J s, JavaScript live coding, something like that.

A

Not practice, it's not a music performance, whoops.

A

Web development, not game, develop engineering. Sure ask me anything sure I can't do that. What should I take out for ask me anything engineer, engineering and it doesn't matter I, don't mean ask me anything okay.

A

So what we were, what we need to do is look for the twitch API.

A

Just here, I've only done a little bit of this, so you can see where I've used the twitch API right here. I think I.

A

It's super easy, you just tell it the URL you want to oh, no, no. This is different. This is a this is on the JavaScript client, so I've actually set up an HTTP proxy at slash, underscore twitch, which I I like to do when I have clients that are communicating with the server through xhr, sending data back and forth. I'll open up a back-channel like slash twitch, and this is basically a proxy for the twitch API.

A

So I'll have my server catch everything and I'm, telling it where I wanted to actually to go, which is the streams URL and and the server will catch that then I've got a little request handler right here for that URL and it will get the the twitch URL, which I called the T URL for black of a better name, and it will then just request basically just put whatever request you. The client wanted and bundle it and send it on to the twitch API whoops. So so, basically, I didn't write.

A

My own twitch client I just wrote a little proxy on the server cuz. It has to be on the server, because you can't send you know HTTP calls from localhost or from your client cross-origin requests. They call them. So we're not going to do that. So this all just gets hit proxy through the server and on to the switch API. So on the client- and this is the JavaScript literally all I'm doing here- is making the ajax call to that proxy URL, I'm telling it here's the ajax or I'm excuse me, here's the API endpoint.

A

I want you to hit and then here's the and the parameters are all up in here too. So I'm just saying give me all the streams from the user that was specified on the client, which was rhyolite and that's what happens so and then I have a function that just renders that data that blob, you know jason blob, glob whatever render stream. So the idea being that I can call render stream on any stream object that I get back, whether I call directly for it and retrieve it back or if a web hook.

A

Who delivers it to me at some point in the future. So now the server. So there's two things that need to happen here: the server when it stands up it needs to communicate to the twitch API and establish a web book. First.

A

Where's, the docs Docs.

A

New Twitter API web hooks guide all right here we go so a subscription when you submit a request to subscribe to an event with the subscribe to unsubscribe from events endpoint. Let's open that up.

A

Alright, it looks like this webhooks hub and the body pram, so it expects a hub object and with a callback, that's a URL, so that'll be specifically the URL my deployed server, because I can't make it local host I'm going to have to test this on the deployed server. That's the hard thing about web hooks. You you have to deploy them to detect, to test them or like send them through some proxying service, which I'm not going to do I'm just going to deploy it and test it.

A

Occasionally, I will need to ssh into the live server. I've done this before and change code, but hopefully I won't have to do that. So I want a function to subscribe to a stream specifically.

A

Mode, oh here it is mode subscribe, topic, user, follow stream change, that's what I want stream changed, so I want to call this URL. So, let's start making this request we'll just we'll just create a function. This is going to be server side and this is going to be like, as the server is standing up like it's coming online and it's going to go subscribe for web hooks.

A

It might get something I might expect to do this many times over and over so I need to make sure that it can figure out that if it already has a subscription, it doesn't need to do it again. We'll see what the API responds with some web hooks some web hook, API seem to allow you to fetch how many subscriptions you already have and man them. Some of them will just only let you have one per end point will we'll find out.

A

So I already have a I, already sort of put a couple placeholders here for streams and web hooks, but I'm gonna ignore those right now and all I'm gonna do is write. A dumb function looks like I already tried to do. This once check this out.

A

Update web hook subscriptions so that's a good function name. So let's say that's that's what we'll call update web hook subscriptions and I don't have anything in live streams.

A

I'm not gonna, do this I'm. Only so I was thinking something different before I'm just gonna use my stream ID stream ID. This is gonna, be real light. I had this initially on the client.

A

It's fine I'll leave it in both places. For now I mean, ideally, you wouldn't want to have it in both places, but for now I, don't I, don't care too much. So I don't need to do this I'm just gonna. Do it for one stream this I was I was assuming I was gonna need to manage my own web hooks so we'll see. Maybe we won't need to do that so I'm, gonna, post and here's the URL I need to post to this one, the hub, it's not a post. Is it yeah post?

A

It's a post and I need a Jason body, so right form data hub callback base URL. So here we go so the base. Url is not localhost, it is gonna, be what was it a rope you open? This will open the web app. Here's some people out in the hallway come on open that.

B

A

There we go, this is the base URL.

B

A

Base URL I'm not going to put a delimiter in it. I'm gonna remove this client ID stream, ID I'm, not even using this twitch. Why am I? What was that.

B

A

Which am I even using this I, don't think I am.

A

Yeah I, don't think I'm, not even using this anymore, get rid of it. Let's delete it. Okay, so I can remove it.

A

So update so I'm going to when the server starts up, we're gonna update webhook subscriptions. Let's just call this leave it at this. Okay, we're just gonna, do one with a new stream monitor, so I want to get web hooks back to this URL, which I haven't established yet right and when I get back to that URL I'm, just going to log it out, I actually have to cache it right. I have to let the client know that I've got something new.

A

So a way to do that would be like WebSockets are polling, so I could have a socket open and always send back information in that request handler. So that's that's one way. I could do it, but right now, let's just worry about the server. Let's not do too much at once. Worried about the server will just console.log out what we get back in that request. Handler, assuming that it exists. Let's make it real, quick and just dump whatever it gets.

A

What did I call it Twitter web hooks, we'll just dump whatever it gets.

A

We'll just console.log requests now it should either have a query. Let's do query and/or a body right.

A

Our Dark Side of the Moon is over. Isn't it body or is it requests here? I'll we'll find out. I can never remember everybody's just everybody's age, HTTP servers are all different, hey look! My my estimated viewers is the same as the actual viewers. This is not estimated it's just hard coded. It was the amount of viewers I had when I made the switch.

A

This is going to eventually update automatically that's what I'm working on is to get the viewers the time streaming and the name of the stream to update every time they change so so I'm setting up a web hook from my twitch server I've got a little OBS overlay server. That's what's displaying this stuff here and that's where that's what I'm writing right here.

A

So it's gonna hit the switch web hook, so I'm just gonna log out its subscribe and then the other thing was a top was a topic not this topic stream change. So it's a string strange. It stream changed. Okay, so wait a minute. What does it mean by that? It's a string, a hub topic, a URL, oh for the topic to subscribe, or oh so it's just a URL to the the actual API endpoint that you would call to get this update.

A

That's clever, okay, topic streams is that all I need least seconds number of seconds until the subscription expires default, allows you just test subscription creation workflow without creating any subscriptions, so do I want to unsubscribe first.

A

So that's the thing I never know if I subscribe subscribe subscribe. Does that mean that I'll have three payloads come back to me or I? Guess that's I! Guess we'll find out. Let's find out that first, okay.

B

Let's assume this is going to work.

A

Oh, the secret okay.

A

Yeah I guess I'm, not gonna. Do the secret right now, I might do it later. You guys could hack my server if you wanted to, but I trust you sort of I'll make it hardened a little bit later. So, let's see what happens when I subscribe to this. If your subscription request passes review, oh when you submit your request, is asynchronously validated to confirm you are allowed to create a subscription, depending on the results of the validation twitch responds by sending you wanted to get requests subscription verify.

A

Sends your request to confirm that you requested the submission the subscription to confirm you must respond to the request, with the challenge token provided in the query parameters and an HTTP success response code. Alright, so first, let's see what we get sent back and then we will respond to it appropriately.

A

So let me make sure that I have my code in place here. What I would do if I were writing a real web application like production web application right now is write is, is, is write. Some curl requests right to hit all the API endpoints and get the data packages that I expect to receive from all these endpoints and then write tests around them, but I'm not gonna. Do that right now or at all, because this isn't really production code. This is a twitch server, hack.

A

Yeah it's a twist around so when this starts up, it's gonna call update web have subscriptions, I am just going to console.log some stuff log, creating stream web hook or I have to tell it. I have to tell it what user right so there's something that I don't understand. I have to tell it those online offline, Street title changes our game.

A

So how do I specify the user, the URL for the top to describe two topic maps to a new twitch points for these topics? User changed.

A

Oh, is it based on my nothin if identification well, I, don't think so when I call the twitch stream like here stream changed the the stream endpoint allows you. Oh oh.

A

Required query string parameter user ID, so this is.

B

What I expected.

A

You have to tell it a user ID, so I think I just need. Maybe maybe I just need to use your ID here.

A

Let's try something: I'm gonna, try something watch this sometimes.

D

A

Is this works for AP is unauthorized: let's try user login, I'll light unauthorized yeah, so I need a client, ID I. Think I already have that baked in maybe you're right, maybe it'll just return me. The one I'm currently that would be great if it did I would eventually like the ability to get other people's streams, though when I, which I know you can do, but maybe not through web hooks, maybe the web hook, you only get your own, which, which is okay.

A

I can I can deal with that hi, duh, hi, Tarzan and and damn gosh nice to see you guys in chat I'm still trying to figure out like the best way to see chat and do live coding at the same time. So if you have any ideas, let me know, and once I get up to like 50 viewers, I think I'll have the ability to like more abilities to interact with my my chatters so like making people VIPs and stuff like that.

A

So if I see you guys around a lot, then I'll probably end up messing around that fashion to okay, so I'm gonna deploy this and watch it break because I know it's gonna break. This happens. All the time static, I, deleted, twitch, okay, good I'm, a first attempt, webhook sub I know this is not gonna work. I know this is not work. It never works the first time. If it did work, here's what I expect to happen. The server would stand up.

A

It would start serving static files so so that you could get you know the overlay here that would that would work.

A

The I wouldn't try and load it. Yet, but after it's served static fire, it made sure to serve static files. It would call update live book subscriptions. It was should log to the console. So I should see this log and that's what I said: that's where I stopped and then it should post to this URL, and we should get something hitting back right here and if that doesn't happen, something went wrong.

A

So I really hope. I will be able to see some console logging coming out of Heroku as soon as we deploy this. Oh you know, I should do and NTA OBS oh come on Oroku logs tale, and we now we can see it as it deploys and we should be able to see those logs if it worked so state change, stopping all processes. What happened? What happened? Oh yeah, it's just killing and restarting error error. What happened source creating stream web hook for okay and then delay stream?

A

What source on it's not a function!

A

That's unexpected! That's something inside a library source on is not a function. So so this seems like an event error of some kind. So I can trace this back to request index so index 53 index 53. So it's right here! It's it's! This request, post I've never tried this before so I could be using the request. Api wrong.

A

Well, I've used the request API before, but this exact line of code I have never attempted to use before I may be not using the form data properly. Maybe I'm not formatting the data right.

A

Let me look it up. So NPM request.

A

Post, which is what I'm doing right post to a URL I'm trying to get some form data posting, with jason, using NPM request, yeah, similar to what I'm doing form data. Oh I'm, not sending this I'm not sending this stuff, so it probably should, in the previous.

B

A

Was I we're in the twitch Oh in this this one? Okay, what did I just do what happened just that? So this is the proxy that I set up from the client when it's trying to make twitch API calls, and this one creates this header, so I probably should create this header properly and I have to do post.

A

So let me try this. Let me try creating the header properly. Okay, my options with the header is with my client, ID and then I think I can just say, method, post, I, think I can say, method, post or request post.

A

Let me just go back to the request: the actual request, Doc's, which is a great place to be.

A

Thanks for watching you guys to see five of you chatting are you: are you chatting because you're interested in web development or HTM, because I'm sort of only doing web development at the moment, I will do H I will use this to do HTM stuff in the future. What I would like to do is once I get like my little. My tooling server up, that is, connections to twitch the twitch API I want to run HTM on live twitch data and I could potentially update the live screen that you're. Seeing like on my stream.

A

I could put anomaly indication or something about my stream, so I think that would be interesting to do. You guys could watch me do that I might use a JavaScript implementation of HTM Oh HTM is hierarchical. Temporal memory is a type of artificial neural network, based very strongly on how the brain works in the neocortex, especially the pyramidal neurons and their connections between layers inside the neural cortex. So it's an AI technology, but it's still very, very new. It's not in play right now.

A

It is not deep learning it's different, but we've been working on it for a long time been researching how the brain works for a very long time. My company Numenta, as you can see up there, says Numenta org nice.

B

A

All the things I appreciate it: good luck on your home repair, I'm, happy to be your background. Noise! It's better than television nowadays! Isn't it okay, I, don't want to pipe I'm, not streaming. All I! All I want to do is see the docs for oh, there is this. It I think all I have to do is say type and promises. Async.

A

Requests wait. Let me, let me say, post post post, if I don't want to put I swear, there's a way you can. You can specify post bit king mark you're, there I'm really happy you're here, mark I. You must not be at work right. I have to figure out how to I'm, adding you as a friend, oh I, can add friends, I'm going to add everybody's friends.

B

A

I'm just trying to figure out how to properly post, I guess so yeah. Thank you for following he changed styles. I was weird I appreciate it I'm the more followers I get the better like the more cool things. I can do on Twitch, apparently I'm still trying to like figure out how everything works here. But it's pretty neat. It's neat stuff. If you're watching on the Twiggs twitch, they a P I, think there's like a heart button or something that's the that's the one that makes me happy.

A

Okay, I'm just dawdling now what I need to do is I'm already saying post I, think I'm already I.

A

Think I want to put this forum data into my options like this, so I'll keep the headers there and also have my form data here, and this is really the payload that I'm sending to the to subscribe to the streams topic. I am for those of you who are lurking, I, don't know if you're here mark but I'm working on my on my twitch overlay and eventually I want to integrate HTM into it.

A

So I'm hoping I can because it's all JavaScript might use Paul's HTM implementation and try and do some live streaming and analysis on twitch streams. You know because I think that would be. That might be interesting. We also I, don't know. There's I have other ideas of things that we could do live like HTM visualizations. Perhaps that could run live and it would be a fun interactive experience to sort of build those with the the community and and show them working as its as we're doing it.

A

I'm like I'm super excited about twitch I, asked I talked to Jeff about it this morning and he got really excited about it. There's a potential will stream research meetings cross. My fingers I'm just keep keep keep waiting, and if we do that that benefits you even if you can't watch live because then we can then I will you know I'll archive them and you can come back and watch mine YouTube later all right options, headers forms, so this is and I'm actually going to add my URL into these options.

A

So, let's put it here: let's put it in front of the headers. So the URLs first, these are my headers. This is my form data and then we just post the options like so, let's see if that works. Let's see if that gives us a better error at least I'm hoping it will I'm side step in the wall. Don't know if I'll get flagged as a naughty dog.

A

You never know you know. You never know good luck to you on that. If you can do it on your phone, I mean if you're on your cell data plan, there's nothing to do about that. I would think, and a lot of people watch twitch on their phone I was surprised as anybody else watching on their phone of you. Five anybody at all I mean surprising, I, also hey somebody's in voice.

B

D

D

That's why I was saying that I like what you did in one false Ananke, be okay,.

A

Yeah I wonder what the experience is for for places with low bandwidth. That's why they say to always export to YouTube, because the there it's much better in low bandwidth areas, but thanks for watching anyway code. All the things says he watches on his phone. Occasionally to sir company, provides yeah over Wi-Fi they're gonna filter that but.

A

So hey, how do you say your name? Is it Roz van Robin.

D

A

That's von excellent.

D

A

I'll just call you Freeman, that's fine, too yeah, okay, I'm about to deploy something- and this is just web dev- pretty much attempt to fix, request bug in webhook, so you can rate my get my get commit messages if you want in the chat, get push I've historically bad, get messages alright, so we should see the the server logs start moving. Hopefully there won't be another request, error or stream error or something I think it's just because I didn't form the request properly.

A

The server is starting. Oh, we get the same error hmm from the same line. What is could be causing that, and how can I get more information about it? That's the question so again.

B

A

On wait a minute request index: oh, that's the module, ok 6161! That doesn't make any sense either. That seems like it didn't get updated. Oh that's the wrong! Yet I keep looking at the wrong file. 66, ok, yeah, so this would be them.

A

So what is the deal here? I'm think I'm, just not using the requests library properly. That's most likely what it is. So let me bring it back up again: no js' request post.

A

Post data with request module on nodejs, I always go to stack overflow, alright, post headers, euro body, so I, don't need form body, but the body is gonna, be a string, so I can make it anything. I'll just make the body Jason. That's probably what it's expecting is a JSON body, not form data. I bet! That's the issue, that's typical of modern api's too. So this object that I'm calling form data free Oh.

A

What's this link Freeman just sent me I must say I'm trusting the links you guys are said how to have different quality options on my stream. Oh, oh, hey! Look at that, but it no there's. That probably means there is no way. So what I found that with twitch? You can't do this and also you can't it's illegal. Well, it's against the Terms of Service to stream, to twitch and to stream to any other serving live livestream service because I wanted to do.

A

We do HTM hackers hangout once a month and I'd do it on Google, Hangouts and I. Initially, it was looking at twitch for a replacement for that, but and I wanted to do one where I did stream to both at the same time, because I think I technically could do it. But apparently it's against the Terms of Service transcoding is guaranteed for partners. I am NOT. A partner. I will be an affiliate when I reached 50 followers, which is pretty soon I'm hoping what am I at now.

A

Forty something so I get to be partner, 45, so yeah, I'm close so as soon as I become an affiliate. I will get some benefit of that apparently, but a partner I think you have to have 500 followers or something like that. I can't remember it's it's way out there: okay, so I'm gonna. So my headers looks good my bottom eye, your L looks fine 46, oh right, 46, only four more to go. I promised myself. I wasn't gonna, be one of those twitch streamers. That's always like Oh.

B

Somebody please.

A

Speak follow I'm, so close.

B

A

And I'm not I'm, not saying that. So, if I'm gonna make this the body I'm going to strength, Phi it stringify the whole.

B

A

The headers should be okay, so I'm just hitting post yeah post those options. You know what let's get rid of the options. Let's just be explicit about this. You don't need a variable if we don't variable and we'll just post and dump everything in there. So it's all in one place all right. Let's try this. Let's try this and see what happens. Hey, Mark thanks one more I appreciate it. I, don't know how delayed was that like how long ago did you click the button? I know it's pretty delayed.

A

So, ideally, my the server I'm working on is going to catch those those events and I'll be able to do something completely custom on screen, so that could be fun a lot of crazy things. Other people are doing. Ok, I'm deploying I'm gonna, deploy it I could basically just run the same. Few commands I've been running, get add, git, commit attempt to fix, and then what's the next one get push origin get pushed or okay master.

A

So as long as I'm working on this bug, every commit message is gonna, be the same until I get this bug fixed.

A

If, if you were seriously doing web program, I think I've said this before I used to be a professional web developer and I would I would make prototypes like this all day long, but this is not how you would build a production web application I'm just letting you know that you know I make a lot of little tools, I'm a tooling person, but this is not a production. I mean you'd. Have you have to harden things a bit more?

A

You know you have to make sure every URL you expose is it's being careful about how it processes everything it gets? Okay, what happened here it worked was what happened. It worked.

A

He used to be a professional web developer. You took an arrow to the knee I, don't understand what that means. Is that it is that, like a metaphor for something.

A

Yeah and also test with different browsers, it's a meme, my kids would probably get it. My kids embarrasses me with memes all the time. I was at a sixth-grade science camp last week, Skyrim, okay, cool anyway I was at a sixth-grade science camp last week, and the amount of memes I was exposed to was just intense I had no idea that there were so many memes floating through the brains of sixth graders and some that I had never heard of.

A

Before some that I mean they would go nuts over because the counselors you know the camp, they call him natural ists. Why isn't it slogan? Okay, something something's wrong and I'm, not getting I'm, not getting that payload I was looking for. I was I, tried to log out it says creating stream web hook, but it doesn't look like it ever received anything back. So, what's up with that anyway, these natural ists knew the kids so well. They knew all the memes they would respond to.

A

So the big ones were big chunga's I, don't know if you guys know well, I'll show you I'll, show you a big chunk of. So you might as well, you might as well know what big chunga says here. It is: it's phat, Bugs Bunny.

A

Look at this 4.1 million views. Okay, because of somebody put this up and then put a weird, the kids like love. This.

A

So that's a meme I, don't know how it happened or who created it or why these things even occur, but that the kids went nuts over just referring to big chunga's, these sixth graders, it's crazy, the children, the children, understand the Internet much better than the adults in in human society right now, and and if you don't believe that you better take their take. The blue pill is that.

C

A

Take the right bill: okay, my wife is gonna, be here at 2:30. I have time, I have a long time. Why didn't I get a request here? So here's what I'll do I'll try and hit this I'll curl. It I'll just hit it with something. So let's say well, you know I should be able to just hit it in the browser.

A

That's interesting: that's got a port on the end of it. It didn't used to have a port on the end of it. What's up with that hold on a sec hold on a side.

A

A

This should last time it did not have a port there's, no port there. Okay, what's why did the last time it open with a port? That's odd, okay! So this worked now. Did my console get so I still didn't get a response from the web server, so something still must be wrong or else I'm. My response URL is wrong and so I'm just gonna hit it right now. I should be able to just put it right here if I put the URL right and it should at least do something you should have logged it did.

A

So it's requests its receiving requests that this one got an empty empty params in an empty body which is fine, but it's receiving requests at this URL I just have to make sure that the URL that I'm using to register the web hook is correct.

A

Naturists no I, don't know what that is. I don't want to know. I can imagine. I can imagine.

A

Okay, here I think maybe the base URL plus. Maybe this is wrong. It could be. Let's do this just so. Let's say: let's: let's set this right here: a callback URL equals base. Url us why'd I. Do that.

A

Let's do this, and so just so, I can log it properly.

A

For I think I can just do that. Actually, let's do this, the like the new cool, JavaScript D way with the backticks I love this. You can do this in ECMO script.

A

Six you can just put you, can just do string, substitution and and a back text string, which is it awesome, I love that so this is only going to work on the server. So I just want to make sure that that I am.

A

Hub so I'm telling it to go to the hub, I've got the headers. I got the body, the body has a subscribe, back, ticks, aren't a meme, are they Beck? --Tx are just a thing and on the keyboard, I don't know if they are I, don't know.

A

Subscribe to this topic call back here: I, don't this isn't gonna help fix anything for sure, but.

A

That's my deployment. Script is up up up return up up up return up up up return.

A

So at least um I'm hoping I'm just going to verify that the webhook URL that I'm attempting to request make a request to is valid and then, if, if I can't tell I'm gonna, send a crow request to it and make sure I get back some response. I should get a response that says invalid request or something.

A

Here we go and then once I do get this working we'll be able to update all this stuff on the bottom row. So it's not! So it's not wrong because right now, it's totally wrong extreme in 18 minutes now. I think I can fix this if I like, if I mess with the stream like if I hide it and bring it back or something yeah, yeah yeah, so it'll rerender it and it will reload it.

A

So now it's it's correct right, but and it's got the right viewers and streaming to ours, but that's just because the website was initially loaded. I'm trying I haven't even written the code for the the server to connect to.

C

A

And update it at all, oh.

A

C

A good point, so I can turn.

A

My game down: that's up! This is better. That's probably a lot better. Does that sound, better I appreciate the feedback on that, because I I it's hard to find the right setting I can see the decibel level here. It's here we go. I'll show you so.

D

D

A

Great well I appreciate that and I can still turn it down a bit more, even if I need to so. Let me know: Thanks, okay,.

D

A

Instant feedback, okay, so I deployed the thing and now I want to see it show so it says creating web or stream web hook. For this.

B

What is that? What is this.

A

Oh, why is that there it's just telling me what port it's running, that's not something I put in. Is it No.

A

Where did ya? What is this? Is this a console.log I? Don't know why this is. This may be something that Heroku is doing. Probably or oh I bet it's it's something I'm doing when I start the server right here, yeah! Oh, that's where the port came from that that's where this is coming from. Okay, so it's! This is just popping up once the static HTML or the static file server is online and I am still so.

B

A

Url that I should be getting hits to okay I'm, just gonna curl I haven't done curl a long time. I.

A

Forget how to use curl every time.

B

A

I just want, like it quick I, think I can just dude curl that what's there's one I always use girl, something because it headers. Why isn't this working I'm a really bad at like network stuff I've, always been bad? Oh, that's! Not what I want? That's, not what I want at all. Let's just do, let's just curl that lets you it okay to know what option I'm supposed to be using with curl to show the headers curl show headers how to display request headers with command line, show HTTP response header using curl.

A

That's what I want I just want to see there. It's just I, so this doesn't seem like it's. It's responding at all.

A

That's like a bad sign. Why not? Why isn't it responding at all.

A

Yes, just waiting waiting waiting and the logs show. Oh it's because I'm not returning anything I'm, just locking up the thread, I'm, not writing out to the response at all. Obviously, so this is not a problem on my side.

A

Well, it's probably a problem on my side. Honestly, it's just I! Don't it's not with my request handler it's a problem. It still seems like a problem with the requests that I'm sending in, but I can't figure out what I mean it should give me an error back I should when I send this. Oh I know what I should do. This is obvious to me now: I need to I'm gonna post this, but I also want to get the response back and I'm not getting the response back.

A

I'm, not I, don't have a response handler, and this is stupid. Obviously, npm request response body requests for requests, promised request, request.

A

I, don't typically use promises, I tried to use promise, I, don't know I just so you basically are just gonna, send it a function as the last probably just the last argument. I'd. Imagine that's gonna work post.

B

A

Then function, which is a callback, so let's see if this works.

A

Hopefully this will tell us something right. This has got to tell us something about. What's going on, vvv I figured out what it was well I'll. Try that next time, cuz I don't know what vvv hands.

A

Okay get Ad index it come it good push or seize happen again and hopefully we'll see.

A

This is something I could probably test locally I. Could attempt to I can attempt to create a web book from any location anywhere?

A

The final authenticated, which I think well I'm, sending the client ID, then I could tell it to hit this web book URL. So I don't even really have to deploy this to test. What I'm doing right now so next time, I won't.

C

A

Should be coming, oh here we go with status, 400 error. No bad request must provide a valid content type header with a crust body. Please use application, Jason, okay, great at least now we have a direction.

A

At least we have a direction and I'm pretty sure. I can test this just by running it boom bad request. Yes, so let's get this working so that we get that web of registered and then we can test it after we deploy it. The extra views are not necessary, though curl used for both. It shows the headers and responds okay, cool good to know. Thank you. Thank you very much.

A

Okay, valid content, type header, so I need a content, type content, type application, Jason I think is what I want to use there. Yes, so maybe that's all strike.

A

Bad request, hub dot mode is required, but I do have hub mode.

A

Yeah absolutely once I get it. This is the hard part. The hard part is established honestly, the hard part's. Seven things go super fast. Once you get this plumbing done, you can do all kinds of stuff. So that's the fun part you're watching the the sausage get made right now. Once once we get these communication channels established, we'll be able to do cool stuff. I still haven't figured out because I want to run an HTM. I could run HTM on this server.

A

I still I need to probably have some state which I might just hold in memory. I'll, probably just hold state in memory, but I hate. What I will see we'll see? Those are future questions. Hub mode is required. So now I don't quite understand. My body is, should have hub mode, let's, let's just pull this out and make sure that the stringify is working properly.

A

Let Jason body equal that oh I forgot that friends, okay,.

A

And I'm also going to a Falco yeah. What do you think about that? That's what I'm working on was streaming. It's not updating live, though so I'm working on the updating live part. When the server stands up. It goes to the twitch API and it gets my stream info and it puts it on the bottom of the screen and then it doesn't update it ever so. What I'm working on now is when the server stands up.

A

It registers a web hook so that it can catch updates and then notify the client, but I have I'm just to the part where it's subscribing for a web hook.

A

Mcu dev kits, what's MCU yeah I, think it's pretty much like that. With a lot of engineering work, especially programming type work, you get. You have to do all this plumbing to get to a point like where you have a platform that you could do the cool stuff with so I'm still trying to figure out why my Jason body isn't being decoded, or it's telling me that hub mode is required, but I have a hub mode. So it must be something with my Jason encoding. I.

A

Think I should be able to see this yeah so hub. Callback modes subscribe that looks good to me. Hub dot mode is required, so something let.

C

A

Go back and look at the web hooks API again at the subscribe, unsubscribe docks.

A

Oh, are micro control unit gotcha, you don't! Oh you don't think I need to string a fight. Good good point. I think you might be right. Let's, let's try the let's do this, then let's try it.

A

That would be excellent.

A

Oops, where did I put Jason body.

B

A

What is what is this invalid? The first argument was this is to request a quest post.

A

Where is the source of this area right.

C

Here, in this request,.

A

Calling stream length of error argument, error options: body set contact. Oh it's a Content link thing. So maybe that's not right, I'm it. It's a body content length, so I think that this is an error because it is expecting a string.

A

Typically what you used to have to do before you had these libraries is you have to create your content body and then you had to put in the header how long it was or how big it was, or else the HTTP server wouldn't wouldn't process it properly, but I think with request. Now you don't have to do that. But I do think that perhaps let me look back at the request. Doc's streaming forms.

A

Request stop post is really what I'm looking for app. Not port post form URL form data. Maybe it is in form data. Maybe it should be in form data. That's what I keep seeing, but I thought you can just as well use body.

A

Mmm-Hmm, let me let me let me look up this noj's request, Jason body.

A

Fast Jason, HTTP POST request. Usually it's something simple and easy.

A

So that's what I thought the content type is usually automatically added. If it recognizes oh, you could just put Jason okay Jason and if you put Jason, you don't have to add the cop that that alright, let's try this brilliance bad request hub. That mode is required. Okay, what? What? What okay? Maybe um maybe there is no hub? Maybe maybe that's just maybe that's just route, no hmm okay, that doesn't make sense to me. Then I.

B

A

This end point web hooks hub I, am sending it Jason body parameters hub, damn gosh forum hub. Oh, you really think that they should be that explicit about it. You might be right, okay, let's try that good idea. Let's try! It I think we can do this with what I just had here and but we'll just we'll say, AB dot. This is a weird way to do it, though I mean a weird way to document it. I would have been very explicit about this at this for the case, because it is not obvious to me.

A

So this is what you're talking about right, and this just be in should be just in the jason body, callback URL hub mode hub topic- let's see if it works,.

A

No Oh hub topic, unsupported topic, hey.

C

We're making progress, though,.

A

Way to go, thank you damn damn and goddamn gosh. Thank you. We're made progress so hub dot topic, unsupported topic, I, sent it streams. So let's look and see why stream chin. This is what it should be right.

A

It says for topic URL for the topic to subscribe to or unsubscribe from topic maps to a new twitch API endpoint. We support these topics, stream change, which is the one I'm going for, and so I thought. This is the topic URL and he'll extremes, he'll, extremes, yeah, API, twitch, TV, he'll, extremes, bad request, hub topic, unsupported topic! hmm Well, right, I, don't know, I am Not sure I could try it. Maybe something else. Maybe I do need to add a.

A

User, you know early. Let me try that I'm not sure, because because I am assuming, this would give you all the streams, and maybe that's not what you want. Maybe you do add user login I'm not sure about this at all. No.

A

No! No! No! That's not it. Oh.

A

How ha ha ha Linda do this? Is there an example, topic user follows and God. Let me look at the guide stream. State has changed. Well, it looks to get streams. Endpoint I, don't see the sample code like.

B

A

Get my book subscriptions. Oh this.

C

Is the forgetting lip.

A

Of subscriptions I'll do that later, I guess up guide.

A

When you submit a request to subscribe to an event, the request is asynchronously validated I already got through this getting notifications, disambiguating payloads, that's a big thing with web requests. I'm sorry webhook subscriptions.

A

I don't know what's going on wow. This seems like from the way this reads.

A

That, if I want to be notified of excuse me, we go back if I want to be notified. Where was this.

A

No, no! No here it is okay. This subscribe to unsubscribe from events end point: that's that's! That's the important thing, or now this hub topic URL for the topic to subscribe to or unsubscribe from topic, Maps to a new twitch API endpoint. What does that mean a new endpoint? Why is why new? What is new about it.

B

A

User follows and each one of these topics has query parameters, so you must add the query parameters. You must add the query parameters to the request. Let's see I should be able to do. This. I should be able to say streams, user, login, rhyolite and it's unauthorized, but if I provide a valid client ID, it should not be so. Why can't this be that.

B

I've got my client ID.

B

So two toward it I, don't.

A

A

B

Me try to use your ID.

A

What is my user ID I, don't even know.

A

I've gotten it before: let's try a different. Let's try subscribing to a different topic. Actually, let's try user follows so I assume you have two.

A

Notifies when a follow of it occurs, then the response mimics get user follows endpoint, required query string parameters first parameter must be specified, which must be a one.

A

Okay, so you always have to specify first and always has to be one I.

A

Think that's just the count right, the first X number of followers, but in this case, if you're going to subscribe to a web hook, it has to be one so in the case of the stream, the stream one down here required, oh I, have to provide the user ID. I can't do this with the user login, so I just need to find my user ID, which I can do because I actually had a function to do this. You know what I'll do I'll do it in the client, because it's probably going to be easier check.

A

This out, twitch get user, earn it yeah, I, get user rhyolite.

A

Response no I'm, just gonna just going to copy this.

A

And because this is super easy because I created a HTTP proxy and so I can and and I'm not gonna render the user I'm just gonna I'm, just gonna console log the data, so I can get my user ID.

A

So this doesn't exist. This does so we're just gonna call I'm just gonna create a get user function. Real, quick, it's gonna, be super easy, simple, it's going to twitch and it's for users and the user. Login is logged in and that's it and so and it's called get user.

A

So this should work from here. I hope. Does it not? Oh, it's got a I gotta go to the browser and you look at it.

B

A

Localhost 5,000 and it should be in the console, failed to load. Oh no, it crashed well, crashed am I, not I'm, not running it. Hold on I was running it in in here right. Okay, this bad request. Okay, bed, request home topic, unsupported topic, oh say so. It died when it did this so I just did the mixture. It doesn't die. Okay, okay, so down so down I'm, just gonna not update whip up subscriptions. For this moment, it's just so I can get the by a darn user. Id oh, come.

C

On why is it crashing.

A

It's not crashing, it thinks it's on a different server, I think base URL.

A

Okay, there we go but connection refused text refused. What is the.

A

Widest collects, refused I've done. I did this before get stream connection refused? Was that or was it which one was it.

A

Let's provide an ID, login or OAuth token I did I did that I.

A

Had this working before in the index.html, were you calling get? Let's just not even do this right now, let's just get user.

A

Okay, here we go get user and we are calling we've got our hyo we're calling the URL twitch okay. So that should- and we should end up in here in this twitch proxy and I'm gonna start. Maybe I should start logging sort of this proxy that we're doing here, the Oh Falco. The I realized that the problem was I can't use. My user login I have to use a user ID, which might be which wasn't obvious until I read the docs more carefully.

A

Okay, I'm gonna log.

A

Let's do backticks again oxy HTTP call too.

A

What was it TRL.

A

To your oh I'm, just gonna leave I'm just going to do that.

A

And I, so I should see.

A

Yeah proxy called 2 twitch users, but it says bad login token. Client ID should be one of the options unless I am overriding it somehow I might be. I might have changed something. Let's look at the options.

A

Actually, the ops, maybe I accidentally stripped something out.

A

Well, my client IDs, their user agent is their URL user. Login rhyolite ie must provide an ID login or user token.

A

I had this work on the other day, oh I, wonder.

B

Stream ID client, ID, yeah, I guess I should.

B

A

So now my my just my basic twitch HTTP proxy seems to be broken and I'm, not sure why it says. I must provide an ID login, our Roth token and I have provided a client ID here.

A

I'm, providing a user login, but maybe I'm just using the wrong term for users user follows user; no, no! No! No, no I want the actual reference to get users get users. Users see it's just ID or login. That's my problem! Okay! So if I'm gonna do get users I have to write it, not a user login, just login right, okay, I think.

B

A

So now we should see that payload serve it siren. You.

A

A

Okay turn the corner. So now we have something wrong because I'm trying to log something it does exist so response data. This is gonna. Get me my user ID come.

B

On open up, let me see it response.

A

Data there, it is that's my user ID all that so I could get the user ID, which is a bit silly, but I did it anyway. Okay, so I am gonna stash this somewhere cuz I'm. Only ever gonna use this on me right at the moment, user ID.

A

Should it be it mmm-hmm, should it be an integer, let's make it? No, no, no I'm, never gonna do any math with it.

A

Okay. So now now, finally, I'm gonna turn this back on the get stream and I'm going to turn this back on, update webhook subscriptions, okay and I can of this and I need to use. So back to the topic, the streams topic streams.

A

Changed I need user ID, so this will be user. Id equals hey, let's use our handy-dandy backticks for string substitution that will be user. Id. Okay cross your fingers. Everybody cross your fingers, so this should at least tell us an error status code. 202.

A

That's a good thing! No error, undefined status code, 202 that what I forgot that probably means created right, HG, p2 a2 is accepted. Okay, so.

C

I think I got a web hook.

A

So what happens when I register it again, I accepted accepted accepted so here's the question how many web hooks do I have now it's a good question: I, don't know how many subscriptions do I have one or you know five, ten. Let's deploy this and see what happens when I change, my stream, that's gonna, be the big question. All right, I could get if I get four requests because I just made for web hooks, then I'll know something about the API get add index static. What's going on?

A

Oh, oh, oh I'm, getting I'm getting data I.

A

Don't know what I'm I don't know why hub challenge? Oh it's the challenge. They said they were gonna. Give me write so I have to once they hit that URL I have to respond with this code. That's what's going on right now, so they're not even creating the web box. These are all for. These requests are the different times.

A

I press I hit the button okay, so this is good, so I know what I'm gonna get back I'm getting get a get a challenge hub challenge, so I, don't even I'm not even going to deploy yet I'm. Just well I think I did no I'm, not I'm, not done I, know I'm gonna get a challenge. I know what its gonna look like. There's gonna be something called hub challenge. He that comes to this.

A

My other URL, my web hook, URL.

A

And that looked like it was a query, not a body, so the challenge is going to be in the query string. So let code equal, rect, weary and hub challenge, alright and then I have to send it back and then I have to send it back to respond to it properly. I need that back to the docks. How am I gonna? Do this sub sub scribe?

A

Okay, no, this isn't it the guide. I! Think that's what I want right.

A

Sends you requests to confirm to confirm you must respond to the request with the challenge token provided in the query parameters of an HTTP success code? Okay,.

B

So that's all I got to.

A

Do respond to the request with the challenge token, in the query parameters, so I assume that I just put hub challenge and threw into the request like response, dot and hub dot.

A

Challenge code I mean is that it let's find out I, guess I.

A

Guess we'll find out so it will have to deploy to test this and and I.

A

Only want to create one webhook yeah. No, let's deal with that later I. What's what I'm afraid? What I think it's probably gonna happen is I'm gonna be I'm, gonna have a bunch of web hooks, and the next thing I'm gonna have to do is write a little code that, as I up the first thing I do before updating web subscriptions is to get all my web web hosts scription x' that are currently existing and delete them all before I register.

A

That's so basically this server or just confirm that it exists and not create one. You know we could do that too, but I have a feeling. We're gonna have a bunch of web hooks flying around and that's what happens when you do this add index static, commit to many others? What did I just do? What do I do?

A

Webhook, sub challenge response, get push.

B

A

A

I'm, not a coke. Sorry, look unlucky me.

A

Okay, what happened?

A

Nothing good, okay, creating stream webhook.

B

A

The chunk argument- oh I, just didn't, send the response properly. I'm, just I just guessed honestly.

A

Node request response and I think.

A

It's just in C: this isn't no! No, no! No let it just. It should be the same. Api is this right, and so you just send it data, which is a string that is just sent if any parts of our news.

A

How did I do it? I sent it data.

A

I think oh I should be asking for express, not request right yeah. This is an express, no just express this bond, and this is what I'm must it be called I think it should this, isn't what I wanted.

A

B

A

This response, and and okay.

A

Ynn's the response.

B

A

Used too quickly in the response, without any data, if you need to respond with data, use, send and Jason I thought that I use this to write data and then end that doesn't make any sense. I swear, I've done it. Ok, let's, let's do response that Jason I, guess so. I'll! Try that response to Jason!

A

Oh, do I have to say status, OH, that's what that's something I might have to give it a specific status, yeah, yeah and HDTV success response code, so I'll specific well, it should do that anyways right, but I'll just be explicit about it and I'll say: status, 200 status, 200, Jason, whoops, my in the right place is this: where I want to do it? No! No! No.

B

A

Meant to be here, yeah.

B

C

A

She doesn't I, don't know where that came from that's a I for ya status, 200, Jason and Jason. Okay, let's try this and I. Don't think I need to call and then I can just call Jason and that's basically sends a Jason response.

A

So let's try this Oh. What.

B

A

This should be tailing, but it's not.

A

Ask her how to confirm the webhook. That's great I'm, pretty sure she'll be absolutely no help.

A

I'm still working on the same thing.

A

Someday this won't be a lie. The six viewers won't be a lie anymore. There's only two at the moment, I can see. I think you can chat, you can see who they are a couple of bots in there falco freeman mark and some bots that are always in there. Someone called positivity bots. That's always there I, don't know what that is.

A

Yes, talking bots anyway welcome bots.

A

Ok, what happened this time? Creating stream webhook it may have it- may have worked. It may have worked.

A

That might have worked, I didn't put any logging in which is unfortunate, but I think it would have so so I need to figure out first of all, because this is this is the web hook or this is the URL. It's gonna get hit every time. There's a stream update, so I need to understand I need to catch the payload and decide what type of payload it is. First.

A

So, first of all we're gonna say this: this could be a.

A

Subscription challenge, which is what how we deal with this so I'll, say if well, let's pull the query out. First, let's pull the query out. First, let Q equal request, query and then we can just use q If Q hub challenge. Then we know that this is a challenge request and we're going to do this else. Ii we're gonna process, the payload else, I'm just gonna, console.log, query and console.log the body: let's go: let's do the raw body because I'm not sure what it's gonna be in.

A

It's probably gonna be Jason, it's probably gonna, be Jason I. Think I can guess. Let's do that for now.

A

So if I do this and deploy it, which, let's let's run it first and make sure also I- had some console logging in here that I wasn't happy with like this error status code body. Where did that come from I? Think it's I don't need to I, don't need to print this I.

A

Do want to print that I do want to print. Oh this! Is it all right over ivory I'm doing this in the wrong place? I should be.

B

A

C

A

Fine, that's fine! This is fine. I'm, just gonna. Instead of logging, all this stuff, I'm just gonna check for the status code. If the response and response status status code equals to a to a.

B

A

Webhook free subscription validated, let's say, but it's not actually created yet.

A

Awaiting creation.

A

Else throw I, don't know, I, don't know what to do else. Console.Log error just assume it's an error.

B

A

With a subscription validated awaiting creation and we're gonna see more probably webhooks come in here and complaining.

A

Okay, let's deploy this.

A

And see what happens so we're gonna watch it stand up, it's gonna try and create webhook.

B

Doo-Doo-Doo, oh and.

A

I need to put some music on holy.

B

A

Burn through Pink Floyd.

A

Really heavy final disks.

A

Something old or something new: okay,.

C

A

A

Something old, a little King Crimson. This is old enough. What 1974 some really classic progressive rock and roll.

A

Some might even say the fathers of prog-rock, thanks for watching you guys the three viewers, or whatever I'm, slowly going to be putting more content on and hopefully getting more viewers as we continue to work on problems of artificial intelligence, actually move this up a little bit.

A

Okay, let's see what happened when we did that creating web stream, they were creating creating stream web hook with a subscription validated and then did I not put any logs in the I did if there's a challenge, I did yes and PFR in the program list. Oh yeah. Definitely definitely I don't have any yes records, but I should pick some up because they're usually cheap. The problem is they're, usually in really bad condition, but the next time I see a yes record.

A

I will pick it up because there's usually they're just an awful munition, but they're always like two three bucks.

A

Is that the is that the album name you're suggesting there was that another band.

A

Some of the good prog-rock now that I enjoy is like porcupine tree. What's his name, Steven Wilson he's got some really interesting: I love, Spacey stuff, so I'll check it out cool thanks for the suggestion. I'll take a look, love the Spacey stuff.

A

Okay, where was I so I think we created the web hook and sent back the 200 response and got no errors. So what happens now if I update my stream?

A

Let's, let's see I mean I, should see a log here if I update my stream. So let's try this.

B

This is too big.

A

So if I go I think I can update my stream. You have to watch that ad. They can update it here. So I'm, just gonna, add Twitter API wipe its description, live coding, I'm just gonna. Add an exclamation point. No, no! No! Let's edit it to begin. Let's just put a smiley. Okay, update information.

A

See I, don't think I, don't think it worked.

A

Nothing, it worked.

A

So I guess what I'll have to do is call the web the web subscription API and ask for any existing web books and see what exists there, which should be pretty easy. So I shouldn't complain too much, but something ain't right here thinks I have two viewers, but I really have three.

A

Something is not right here, so let me look at the docs real.

B

Quick did I pull that off. I didn't mean to pull it off, go back.

A

Okay, for there is an API endpoint for subscriptions, get webhook subscriptions. So let's do this. We can do this even from the client and use our you know proxy. So.

B

A

Let's start: let's do that I've already got.

A

Is it even worth doing why not? Now? This is a totally server-side thing. There's no reason for me to push it through the proxy I'll. Just do it we'll do it before we update our web hooks descriptions, I'll call get existing, subs, okay and then we'll just subs will be the date on the callback and, like I, said I, don't use promises very often ever read ever I would I'm, probably just an old head JavaScript programmer at this point, but I never liked promises. I mean I'll, make them every once in a while.

A

Okay, so this doesn't exist. So, let's create this function.

B

Function get existing subs.

A

Takes a callback- and this is basically going to do what the twitch proxy does is just going to request- make a request here. Let me let me set this up I'll just copy and paste this, because it's gonna be mostly the same boilerplate.

A

The headers will be the same. I don't need to do this. I know what my my URL is going to be. It's gonna, be this.

A

I, don't need that I.

A

Do I don't need to do this either.

A

Yeah, so I can just put the URL directly in here. I'm just D complicating this because.

B

Let's take this.

A

Okay, there's the URL, the headers and then the query string, query, string, I, don't know that needs to be anything.

A

Is there required current parameters and done an optional Fergie string parameters, so I'm gonna send none and hopefully I will get them all. Okay,.

A

Okay, so I'm not gonna. This isn't a proxy call I'm just going to delete this well I.

B

A

Know I'll just leave it like that. Okay, so I got gyro, I got the headers client ID body is nothing. There's not going to be a body. We're not posting.

B

A

Not responding.

A

In the when I make the request, I'm not gonna, be.

A

There's no body and I don't need to send set that all I need to do.

A

B

C

A

Back, let's just see what it sends back.

A

I don't know if you can hear that like a I guess.

C

A

It made it past the skip, never mind.

A

Okay, get existing subscriptions I'm, not using the options properly again, I'm just going to put them right into place.

A

Bent knees start with land animal.

A

Okay, your L headers and a callback.

A

And we're just going to log the let's see, so this should work.

C

A

So these must be registered by client, ID, so I assume using a client ID I can register a bunch of webhook subscriptions to different URLs, and this should return me all of them. I assume they're not identified by the year rather than if I'd been a client ID animal, so we're gonna and I should be able to run. This I should be able to run this locally and then just not do this right.

A

C

Let's just do this: let's just.

A

Run this locally not try and create anything new, and they should at least be able to see, of course, I.

A

I'm just going to remove that try it again.

A

Arguments, nothing, nothing, nothing! Okay, so.

A

There's a whole lot, o, let's, let's debug. This is why I like one thing, that's nice about, that is okay arguments. What do we got here? We have an error which is no the raw body. Unauthorized 401 must provide valid app token, an app token I have an app token. I have an app token, pretty sure so getting subscriptions app. It spoken, nothing, nothing! Okay, token!

A

There we go to confirm. You must respond to the request with the challenge token. No, no! No! No.

A

App token search on the docks down: twitch Doc's setting user access an app access token. Here we go.

A

Register o authorization Bearer- oh oh I, didn't do this: okay, so authorization bearer and an an access to again I can do that. I, pretty sure. I have an access token.

A

Registering your app, which I'm pretty sure I did registered.

A

I already have one I thought: I know: I have one doing that not over you look here this there's an application that says this is the one I created for my overlay that I'm working on I have a client ID. Is the client secret, the app token pastor, the token Australian poison Tina? You must keep this confidential past two authorization endpoints to identify your application, so it must be a client ID. It must be. The client and I must I'm sending it as a client ID, but I will also send it in another way.

A

Maybe maybe that's all I need to do, send it authorization and then bearer.

A

Wyatt client ID I'm guessing here this might work I'm, not sure. Let's try it again.

A

Okay must provide valid app token. So that's not it. Let me.

A

Client ideas here: clarity is not a big secret. It's not the secret.

B

A little confused.

A

Dedication app access token.

B

Somebody's applausing.

A

Register your app to obtain a client ID and a client secret getting a token list. This must be the time when they're talking about getting a token. The domain dedicated to twitch authentication is ID twitch TV years of the favorite place.

A

Access Roth credit credentials flow procedure you should use to get tokens depends on the type of tokens you want, what type it's open to a woman. It says user access token for all these, except here.

A

When an API request requires often authentication send the access token as a header, it's different on, depending on the API I'm using helix, so it should say authorization bearer access to okay.

A

Refreshing access to refresh.

C

A

Of tokens, IOT Toby's.

C

A

Of claims about the end-user user access tokens allow your app to make requests on their behalf if your application uses twitch for login app access. So this is what I want authenticate your app and allow it to access resources that it owns. Since app access tokens are not associated with a user, they cannot be used with endpoints that require user authentication.

A

Ok, some, which is this one shouldn't I, don't think web hooks should require user authentication. Some twitch, API endpoints require application, authentication I think that's my problem. I'm using a client, ID! Well, the client ID is associated with my app access tokens, get client credentials, not user credentials. They enable you to make secure, API requests that are not on behalf of a specific user.

A

It may also be used in place of the client ID headers to securely they expire after 60 days. You should so.

A

For server-to-server API Crescent should never be included in client code. Okay, so I need to set it as an environment. Variable bearer comes across of sending user access and access token did not. So how do I get it? It must be the secret, it must be. The secret see here is the client secret and, and are you sure you want to jail, yeah I? Guess there's the new secret, but you're not I'm, not supposed to show it to you. So you can't see that secret I'm gonna generate a new one.

A

So now I have another secret and I'm saving it. Ok and now I've got the secret in my clipboard.

A

Now I should be able to go to Heroku and set an environment variable in my environment and call it app secret or something like that, and hopefully that's the token that they want I'm, hoping.

A

It's really it's. My volume is way way down anyway,.

B

Close this okay in OBS.

A

Twitch overlay I think it's settings configures, so I'm gonna, add app secret, I, guess and I'm gonna I'm gonna paste it over here. So nobody can see it. Okay, now they're hidden, so I have one whoops.

A

Alright, so I've got this now if I reveal them yeah, it does reveal them. Okay, anyway, I have one called app secret: okay, as a configuration it's an environment variable essentially, and so I should be able to get to that from this code. So I've got my client client ID. Let app secret I'm, gonna, call it that and I'm gonna say: env I forgot how to do this. It's process it's process, DNV, app secret, okay,.

A

A

I guess I want to confirm: it's not like I want to print it to the screen, but I don't want you guys to see it. Yeah I can change it later. I, probably it would be easy not to change later.

A

So what so, now we're am I going to put this in my get existing subs I have to send bearer, and this is going to be app secret. I hope this works I'm, not sure what to do. If this doesn't work honestly.

A

Just try to go. Oh.

A

Okay, I didn't get the environment variable the right way, no js' processed that in the environment variables. How do you do it? I've done this four million times just show me. The line show me the line process, Ian V, dot port, so it's just lowercase in the pretty sure, and then I could just do dot. Instead of it doesn't matter it just treats it like a string anyway. All right, try again all right. The error is, must provide valid app. Okay, he's.

B

B

A

Okay, all right all right.

A

Okay, I'm you're gonna, see my app token now for sure I want to see my payload and make sure that it looks right and just turn that off all right. My header is client, ID authorization.

A

Bear undefined okay, that's the problem, it's undefined! So back to this Heroku reveal config variables. Oh I think I probably need to like bounce it or something I'm sure I need to bounce it. So I think I have to do Heroku, restart.

A

Heroku logs tail keeps dying, Oh, obviously I'm running this locally, so I'm not gonna. Have this environment variable! Okay, I have to deploy this to test. It.

A

I'm still working on the same problem with books, sub challenge response for days.

A

All right, once this half of the record plays on.

A

Let's see what happened here.

A

Something happened.

A

Does it use the it's using the? Oh? That's just that's nothing! Okay, okay! So it did that and now I got to now. I'm back into the all. He did was log the arguments which doesn't give me any visibility into the actual response. Let's.

A

Live debugging here.

A

Soon, this will be less less tedious. How do you like the marquee, though they haven't, seen Marquis in a while I, usually used a marquee tag for that? It's beautiful.

A

Mark he ended up. Oh my goodness. What happened here? Whoa? Oh, that's, the responses, it's getting responses, it's still saying, must provide valid apt. Okay,.

B

Geez, okay,.

A

Okay, I'm dumping, obviously like way too much.

A

What object is this.

B

You get subscriptions.

A

So the raw body is basically the same. I must provide a valid app token, so.

D

I'm not providing.

B

A

Valid app token, obviously,.

A

I think that the thing to do is just continue to read the API and figure out what I'm doing wrong.

B

B

A

I'm going to put the so I can test this right now. Instead of this I'll I'll make this the actual secret, which I had my you're not supposed to know the secret, but there it is, and.

A

Then I can just run it locally. I should have just done that in the first place and then I can see the response right here. Oh that's not third place for that that wasn't the response yeah get existing subs. This is where I want to see the response to stress Ian. So.

A

Right, it says error. No, but it also says must provide valid app token. How am I not providing the right app to again.

B

A

Api must provide valid app token can't get webhook subscriptions in point. Okay. Maybe somebody else has the same problem that I do the twitch developers discuss discourse. I should probably sign up for this.

A

Can I login with my existing Google I think my new meant account this I like this about let's make this rhyolite yay I like this discourse, because you can any discourse site. You basically got your profile automatically. So I noticed a new point for getting web of subscriptions. The response already tells you what's wrong. The endpoint requires you fast and app access to. Is he doing that he's he's sending a client ID thanks I'll, give it a try. All those examples. Activation is client ID, not an app token, that's cool!

A

What I saw to getting an app access, token doesn't work so the example and the documentation couldn't do with updating to get authorized bearer token, rather than client IDs. So I already tried this with that. Using the client ID and it didn't work, didn't I I mean I'm. Pretty certain I tried this with the client, ID and I. Don't think it worked, let's see, yeah that didn't work and the payload looked right.

B

What wall maybe.

A

I need to take out the client ID. Let's try that, oh now, it says must provide a valid client, ID or Roth token.

B

What okay, okay, okay, okay,.

A

Let's try and use the app secret now this is sort of infuriating must provide a valid client, ID or Roth token. I am totally providing a valid client. Id I. Did it right here? Okay, so, let's take out the authorization entirely just send now, it says, must provide a valid app token. Oh, this is nuts. This is making me crazy twitch.

A

What's up with this.

A

Okay say if I say I said nothing: I, don't send anything except a user agent. It's gonna tell me, provide a valent cloud, client, ID or a auth token. I provide a valid client ID.

A

Maybe what doing the client ID right I know I know. I am that's the way to do it right here, client, ID, first, oh, oh, maybe I have to give it a first. Maybe I have no that's not right. They would tell me something different. That's.

A

That's not right, I'm get rid of this. This get rid of this here in this.

A

Record still on it's just like really avant-garde stuff right now,.

A

It's just really weird stuff.

A

B

A

No! No, if this is going to work and go to their ID server and see what happens.

A

Your application uses a server, can securely store a client secret and can make server to server requests. Yes, that's a good authentication flow, so that's called authorization code flow, which is what I'm trying to do. I probably want to do the OAuth authorization code flow. Maybe this is what I need to do: send the user. You want to authenticate to your registered, redirect URI I hate a lot.

A

Okay, then an authorization page will ask the user. This is not what I want to do. This is not I. Do not want to confirm I, don't want to use OAuth I am the user. This is not like a user control flow thing. What is what is? Oh, I DC send the user. You want to authenticate to your registered I'm, not trying to authenticate anyone. I just want my application ID to to work.

A

Your app does not use a server such as a client-side JavaScript. Now you need an app access. Token client credentials flow. What is that even mean?

A

As mentioned earlier, app access tokens are only for server to server API requests, which is what I'm doing the grant requests below requires the client secret to acquire an app access token. Okay.

A

This also should be done only as a server to server requests. Never in client code on your server get an app access token, by making this request post to the OAuth client ID, my client secret and the scope so.

A

I guess I have to do this when I start up my client idea, my client secret grant type scope.

A

It's funny did the turntable crash. It was skipping a little earlier.

A

Implicit comfo.

A

It's not I, don't want to I, don't want a authorization code flow, see that also sends the user somewhere. I don't want to do that requires the client see I think this is what I want Oh auth ooofff client credentials.

A

So this is the post a make.

C

A

This is definitely session management I've, never liked ooofff and I've, never totally gotten the whole Olaf flow. What could I never had to completely, but all I really I think what I need to do is send my client secret client ID.

A

My client secret is.

A

Was what I was? uh How do I find that now there is way.

A

Sign up with I already signed up I should be logged in by now. Okay, Doc's.

A

Account settings serial.

A

Now, notifications for the connections.

A

Where's my apps I know my I have apps.

A

Ii, it's not really wanted inventory subscriptions.

A

How do I get to that twitch applications. I have the patience, No, no twitch developers, yeah yeah, I, think applications. Here you go all right, so I'm gonna manage this application. I don't have to go soon.

A

Okay, so oh I, three direct URL I, don't even I'm, not even gonna use this I don't want to redirect anyone anywhere cuz. This is all gonna be server-side, so I, don't think it matters. I hope, I, don't want anything! They're! Calling this a broadcaster suite I've got my client ID I might create a new secret. I must save to save it. I guess it is saved.

A

Okay, it's my client ID right I could have a wrong client ID. Let's see I'm secret client IDs the same yeah. So that's right.

A

See this this person.

A

They're saying they're trying to do curl, you know what I'm gonna do this I'm going to try this curl I'm gonna do this from curl. It makes the most sense at this point in time and let's see what happens so I'm gonna put my client ID in here. It's just the right, twitch yeah. He looks web hook so client ID, and this.

B

Is not gonna work, I'm.

A

Pretty sure, because.

A

Of the issue illegal characters found in URL, oh I, know I unauthorized right must provide valid access. Token, that's exactly what his guys complaining about. The response already told you what's wrong. The in point requires you to pass an access token, which is this Oh auth.

A

This grant request this grant requests below requires the client secret to acquire so so now I have to post there to get a token like on the fly. It seems like well, I want to read back over here.

A

Thanks for gonna try, although the example, the documentation uses a client ID, not the app token getting an app access, token does work, so the example and the documentation could do with an updating to authorize bearer rather than client ID, so I guess what we got to do is make now this request.

A

To get a token, so I guess is what we're gonna have to do. Let's try it. This may be something we end up only doing once, but.

A

Let's just call this thin to Kate and it's gonna have a call back again, and this is the post. This is the request that we're going to make so request.

A

And it's a post: no! No! No! Let's do post! Okay! Url is.

A

This token right.

A

Once every 60 days, thank you so I'll probably figure out real quick. Whether I need to do this or not, and then write some code to do it conditionally client secret, which is the what I called up there, an app secret so just leave that grant type client credentials what it. What are the client graduals grant type must be client credentials. What does that mean?

A

Grant type? Oh I, oh I, think it's actually the string, client credentials, I think I, hope.

A

Yeah and scope scopes where the scopes, when you crest authorization for users fill us or specify permissions, I want a web hook. One it gives me web hooks.

B

A

Analytics bit information subscribers manage a clip, manage an object. Edit broadcast configuration view, broadcast figuration, I think read: authorized user emails. What.

B

Was he doing what was his scope.

B

Oh, we didn't didn't, say what.

A

Would be the scope that I want? It's not bits, get a list of all subscribers to your channel and check out the user to subscribe to your channel.

A

Which scope it is scopes when you request authorization from users specify which permissions your app requires. These scopes are tied to access token you receive without specifying scopes your acts, your app can access only basic info space separated list.

B

A

All right, I'm still streaming yeah.

C

A

Right well, I'm gonna, I'm, gonna button. This up then, and.

C

A

It's not that's. That's not really. It's three viewers.

D

Very good yeah.

A

This is my son, Dean hi. How are you and my daughter I, don't know she wants to be on live stream or Nile, but no.

B

A

Came up to get me so we're we got to go. We are off so thanks. Thanks for watching and multi-on, hey, you're learning, good, we'll come back and watch again because I'm going to continue doing this, probably.

D

A

Might play minecraft later yeah, but if we do I'd have to come back to the office because I can't do it I can't I can't do it very well from home anyway, thanks everybody for for watching today, I'm gonna keep doing this, so hey I got another follow. Thank.

C

You yeah I'm, almost getting close to 50 all.

A

Right take everybody.
