That's funny Give it up for beardy. He's on he's on the sweat coin app. He walked 88 steps today 88 steps Must have pushed the refrigerator away Maddie see you Panda Pisces Rob show the white paper Bitcoin. It's not a pond. He's just exactly it is You know, we just went over we just read what we went over the Satoshi Nakamoto white paper only nine pages and I I gotta tell you I'd say it in the white paper itself. It's very specific. It is for a peer-to-peer transaction You're supposed to use it. You're not supposed to hold all it forever You're supposed to be able to buy things with it goods and services. That's the whole point of it now People say it's a store of value. I guess you can make it whatever you want to but you know Don't demonize people for them selling their Bitcoin at some point and wanting to pay off their house or Buy a car or do whatever they want to do. That's what Bitcoin was meant to be so Stop with the nonsense of the diamond hand stuff Vicki. Thank you Financially go tax advice chance for empty and prisoning Dan is not an expert obviously World Financial Planner. These are Dan's opinions Please perform your own Dan research But at the Alright Norman what's next in Crippa, which we watching out for you know, we should be watching out for The forgetfulness of the market itself and we've talked with us, you know At length I think about the people who were here before us long time ago Oh geez who had a bunch there their funds and FTX just forgot the principles of taking everything off myself included and What's gonna happen is we're gonna remember that right now because it's fresh But in one year two year five years when the new people come in or even just us Maybe we get a little complacent and we don't remember these things This is why we must be ever vigilant the things that we talk about and remind people that hey Self-custody is imperative. I'm gonna give you three examples. Why it's called voyage yourself to this FTX I know you don't know who they are because this is new time in 2025 2026 or 25 There's a bull run. This is why we do these things because of what happened. So I'm counting on all you guys to help me out Rob contain any good worth it. No idea, but you know who does know did a great video CTO Larson I always refer people to him Or I was any way to set limits on DXD Do I XD Jerry so I'll ever no idea. I know Jerry said it not really familiar with that at all I'm going from there. Maybe Tom crown knows and here he is Was the raw while sharing rule and crypto play this year. I'm not for sure However, good news Tom.  So we'll do it live. Everybody can come here ask their questions and go from there I don't believe so but good news is if you're in the States, we got time. I think April 1315 around the corner Destructive like Lissy all day, sir. Thank you Probably not a good idea. You should get out there and watch other people's channels though Tom crown being one of them Ben James CTO Larson Paul Barone Mike the investor Hashoshi Dan from crypto recruiter, I think it is Who I'm still waiting to do a collab video with whatever Let's see Confluence at 8 to 10 K. What do you reckon DGN? I'm trying to stay away from the DGN stuff as much as possible All right, I did that in 2021, but I still got some plays in there Not meme. It's a lot smaller than I thought it looks like a notebook. Oh memes talking about the The shield folio Can tell the pages are made out of stone, but it's a durable makes me good. Yeah, it works out pretty well I got like three Who Jane Chao what's with the good stuff could coinbase be lying to us that Genesis parent has six hundred K Bitcoin, maybe they sold some to cover up for three Them not transparent cover up because of a security turn just bring more doubt, you know, Jerry Hall had a great point yesterday He said yet to remember that Coinbase is a publicly traded company. So the things they talk about are essentially They're not their opinion, but they can be be held Responsible for the things they put out for their company itself So if they say it is then it's supposed to be and of course that legally They could be in hot water if they essentially lie, but I was thinking about is like Jerry's right first of all, but I was thinking about I'm like, well Everybody's in hot water if they do the wrong thing look at Sam SBF Probably gonna go to jail But who knows so I just wonder I just it's just it is very odd and and I get it but like the thing we just talked about with With DCG group who has you know, they're a part of grayscale and Genesis who are both looking One's looking really shaky and one's up in the air just makes me makes me wonder a lot Do I think the bottom is in absolutely not that's these are the things that make me think that bottom is not in because of these Grace one of it's we'll say it. Oh Thank You Jeff look immediately So I work out every day But the difference is they try to eat more the promise is you get older and you know, you'll know this as you get older It's hard to keep it's hard to keep muscle. You start losing muscle and gain fat But that's why you take you take testosterone. It's usually a lot of works out Let's see Carrie says how are we under the drawing? So yesterday care. We had a drawing for she'll follow do it again And it was just you had to go you had essentially like the video yesterday and then tweets or retweets like and comment on The tweet that I put out about the giveaway on Twitter. That was it I would like to just do a straight giveaway for people here But I got to figure out how to do that and how for people to contact me Over YouTube to where they can tell me their address because you can't just put your address here in the comment section I'll make no sense. I don't know. I'm sure there's a way. Yeah, Tom.  I was gonna ask this question because let's take a look, you know, we never look at anymore I don't really care. I mean, I know I should but I don't I'm the price of crypto and I did I did take a look at it real quick today because I was like You know just to see the market cap, you know, 37 billion. That's sad But polygon 24 hours 7.3 percent. I wonder what the what the partnership was look at life coin 12 percent of 21 percent for the week is That right? Is like coin the number one? Yeah Holy smokes See things you don't know. I'm sure there's a reason. I'm sure there's a great reason for that But yeah, polygon, that's one of my one of my buys me and Ben go round and round about this about buying all coins but I Don't know I still do it and then take some profits along the way I kind of like doing it just so I can remind myself that I can take profits like with polygon just have to get the alerts Let's see Serious is will you marry me? I am already married to the great Great woman. I'm good Ben's YouTube link James Lee team link. Thank you, Bickey Ledger is my only crypto lady to purchase that hasn't Fire that's true. That is true Let's see I show she is underrated really smart guy good guy puts out great content just Isn't in the sensationalism and He's his videos need to be viewed more. That's what it is Army of spies I've heard of that one. Thank you, Nick. Oh, you know what else someone told me that? Musely swap has correct me if I'm wrong, but they said that mostly swap has limit orders on the decks Is that true? That's pretty interesting the Mertesia who helps out me and a bunch of the youtubers to come about the The scams that are going on in Twitter. Thank you my man.  For the Bitcoin Investments can you do it right now? I thought there was a waiting period. I'm coming out with an asbestos fast book I hope it catches on be good for the fires not good for the cancer. Let's see True Voyager what you know what said Voyager was publicly traded and guess what? The thing with them if it wasn't for the fact they were publicly traded and They had to put out their assets and liabilities. I Never would have known that they would have made they made that loan to three-or's capital That's the reason why I put that video out is because because of the documentation that was put out because they're a public-traded company Then guess what I figured out why everybody knew at that point They made a loan at three-or's capital for six hundred forty million dollars and it was uncollateralized And when I figured that out and you can look at hold on let me show you So people are like Rob didn't do that It's a good point, but I have a timeline here. It's in all my videos now Voyager timeline June 22nd when I figured that out I said take all your crypto off Voyager I said I was still gonna use it but I didn't take it off and here's the link then July 1st The withdraws were frozen the difference is between between Voyager and I trust is that Voyager told you look We're not making loans, but we rehypothecate your crypto where anything the yield came from right? So in that situation Then of course they could do whatever they wanted to and you agreed to it. I agreed to it because we thought it was safe Of course when we figured it out you got our stuff off right right right and off we go So I trust is telling you the exact different. They're saying look we don't Rehypothecate we don't loan. We don't do anything with your funds. It's in cold storage And that's it. I mean again, could they be lying to you? Is this something that you that everybody has to do? I'm telling you to do it. No Have to make sure it's right for you Just like with Tom like Tom crown had we had a great interview. I encourage everybody to watch the videos on Sunday He talks about limit orders to just fill those limit orders You got to leave some money on the exchange. He's like I can do that because you know I I'm okay with it, but for some people who are like trying to make ends meet and they live in Pecha to paycheck I'm not telling you to do that. Everybody's different. That's why like I just Even like the random people I just do what you want to do. I'm not your dad. I can't help you Yeah That country says it these youtubers take money to promote scams. They say oops. Sorry. Once your scam be wary I'm not gonna shy away from it. So as far as like taking money per se It's affiliate links. So if you know how to use your fill links, you can go from there, right? Now, of course, once I figure out something is wrong. I tell people as fast as I can But look Celsius the same thing. I figured out the day before Granted, I should have been faster. Don't want to spread foot on stuff. That was on me but Voyager Okay, I Said two weeks before and then also we do these things called the rules Have you seen these rules?  Don't use leverage and take profits on the way So no situations. Yes, and that's it But I won't shy away from it. I made mistakes. I really wish I wouldn't have ever talked to actually now I'm gonna take that back Celsius worked until it didn't Celsius got ahead of itself did something that it's something that made them They were trying to chase yield and they got riskier and riskier Remember in March of 2020, do you know how many people that they had to liquidate because of loans three Because they had enough crypto reserves and cash reserves to cover everything. They were fine Unfortunately as time goes on people get greedy and they get sloppy and that's really what it comes down to and that's for everything Even this channel at some point Hopefully not I may put out this trash Just trash videos that like this is not what I signed up for and at that point you have to leave Because Rob makes trash videos. So remember You know nothing lasts forever That's the problem that that is the problem and that's why you can't say that and forget it You got to be in this game like daily That's it Yeah, that's what it was Sailor said light coin is like Bitcoin on security. So the almighty Michael sailor speaks and everybody says that's great Tom crown Tom crown as a light coin scale Jane chow and he concerned that miners will sell more Bitcoin later. Absolutely. They're good. They have to Some miners are already in big debt because they overextended. Yes If they're shut down through the energy crutch, it probably won't be enough next bucks one Here's another question though The question then becomes How much do you think that the miners have in reserves right now and haven't sold Because here's a good here's a good post because some have already sold some are already out They're out there out the door the Bitcoin miners are done because Not only is it is the Bitcoin mining price decreasing But the cost of energy is Going up exponentially and if you're outside of like Texas and other places they feel the crunch big Lee big time Here's a here's a post. I I got a couple of days ago. Check this out I think the smaller Bitcoin mining companies are hurting because of stuff like this. So this Zach Guzman says just how bad is the crypto collapse my landlord friend in Dallas Dallas just asked me if I know anything about Bitcoin miners the Bitcoin mining company defaulted moved out and left all their equipment behind Which I think is kind of weird. You think that they would sell those at least for some some revenue but Maybe that's just a one-off not for sure, but then You can take a look here at crypto quant when we put on my password one two three four five All right, and let's see dashboard That that that uh my dashboard My dashboard Here it is. So there's a there's a great on-chain metric called Bitcoin miners Outflow would how much are they selling and you can see back here? It was just a cell fest, you know back in the day But I'm just kind of just tapered off now We can see that as things started to heat up man. They sold off massively. You know what this was right here in 2021 Right this big sell-off. This was when China banned all crypto miners roughly around that time and all the miners had to sell So they go to China and go to other places And now here we are let's drill in let's drill down And see what they're doing. Is it anything exponentially different? Well a little Huh, this is interesting So you've got the price at 15 8 quite a bit of a spike here November November 9th But it's been pretty stable the last week or so. Let's take a look at Let's go back a couple months Little spikes. Let's go back back Not as bad as That was a pretty big spike. I must admit so here you got to think about maybe miners are capitulating They're selling off and maybe that's some of the last ones to go and again just like we saw with riot the cost basis a $300 so Bitcoin hits below that you're gonna see a massive sell-off because they got to keep the lights on but Who knows could be wrong just something to look at also always take a look at that well multiple The one looks like Looks like that helps you kind of distinguish like what's the noise and what's not? Let's see As George about the like one movement I'll ask one is next show Okay, there's rumors about something big like when the next six months Well, you know what that means that means I was gonna start buying like when like crazy Just kidding. Don't do that Who knows? Maybe Charlie Lee is gonna buy all his all his like when back after he dumped it at the top in 2017 Unpopular opinion Like coin is useless that couldn't is silver someone found a I guess somebody found something for I'm not for sure Ajan welcome new YouTube member Awesome. Thanks for being a member Fidelity is still a list excellent Oh When the army of wrenches side channel, that'd be a good one. I'll be jarkies here Look, don't expect the jarkies are giving away Memberships like like he always does I mean he's he's got to buy crypto too When shark Thank you, Vicky excellent team Benny Team jarky Uh Could it be let's see Could the jump in new waters being really trippin to see the the rise and in hot coal wall uses that perhaps Who knows? Well, actually Yeah, I looked that wrong Let's see and well gifts. Where are we? Make it rain Tom says I have a friend of fidelity said they open to retail Monday Maybe it's like a soft opening like that's what a lot of business will do is I'll give it to a select few of Investors and just see how it goes and they'll roll out to everybody I didn't listen about where you don't meet yourself up I told you to take all your crypto off. Even I didn't take all my crypto off So all my vgx tokens which right now are worthless. I should have sold but yeah Even I mess up. I mean I'm like I say even I I mess up all the time. That's my wife. She'll tell you I It's interesting point retro restoration says 90% of my crypto has been consolidated Bitcoin The rest is multiplying itself and ate a staking pretty good Pretty good way to do things Bitcoin is sitting in my tracer While I watch the panic unfold feels good to send the sounds for a bit. I got to try a tracer I've been ledger forever. I gotta just try it to see how it is. Does any of use it retro? Do you like the tracer is it like easy to use? I find ledger pretty easy except for the the app sometimes kind of a little screwy John I'm loaded on my soul. It's pretty wise move. I think there's more pain to be but who knows Now Texas we have energy crunches here and there especially when the grid when it's super hot the grid gets It gets taxed Exponentially but the other big thing was the infrastructure was a problem in the in their last We had a hundred a year cold storm in the last year and a lot of people lost power Some people died actually. It was pretty awesome awful But that was because the infrastructure not the amount of energy that they produced Crypto McFly says no one talked about how hot Monero was. I used to have Monero. I still have any more.  Hmm Lots of people are saying Binance is giving up to knock tether off its peg and sink competitors is true Look, I've been talking about tether forever about how I don't trust it Still keeps its peg. However, I will say this everything's cool until it isn't everything works until it doesn't So who knows I just not gonna put any of my Harder money into a stable coin right now I took it I have like 1% in stables, which is in my metamask wallet because when I want to do goofy things Then I'll have a little bit of stable coins there But that's it everything else in cash sitting in a bank FDIC insured, which is amazing How long ago were we talking about how cash is trash? Pay Dalio and now of course now we're talking about how cash is king. It's amazing how that works out But then was right on that one Yeah, Greg said hey Rob wasn't supposed to be a bunch of slotted getting on stake. There was I don't know exactly what happened But you can see the price price did dump the last couple weeks. That's for sure I mean part of that is the FTX right FTX was a big backer of Solana Yeah, exactly pain says if you're diversified across all investments You know how to be in so many coins and crypto if you have too many coins and that's the thing like you guys know I'll know that I'm not I'm not massively I Mean I'm diversified as much as I possibly can be across all asset classes like this is This is my My portfolio and most is in cash 1% I think it's even less than that is in Stables 5% of DGN maybe maybe 3 to 5 percent 4% roughly and masterworks again fractionalized shares of artwork which is Regulated by the SEC and every payment they have is and don't forget do not forget They just artwork just sold 1.5 billion in this in this bear market 5% in land roughly Yeah, it's maybe a little more 35% is in now real estate Which is what me and the wife do mostly Amazon business 5% 15% in staking Roughly 1% I thought it was more and I trust capital one to three But it but the value went down so much because crypto went down so much and then 5% I have in stocks stocks Because why not? Right Paul says do you watch any youtuber that's out of crypto?  Just kidding. I watch I Watch Ben James. I watch a hashoshi whenever he gets around to putting a video out I would have watched Simon you if you ever get a YouTube video our YouTube channel Paul Barone's gets great stuff CTO larson always comes up on my on my feed. I watch the daily brothers all coin daily They always have good stuff Around the blockchain the BitBoy channel every so often I'll catch that crypto Wendy crypto Casey Oh Guy from coin Bureau. Yeah, both channels pretty good Pretty much a hodgepodge. I do a lot of things. So like I when I'm doing things outside I just pop my earbuds in and listen to everybody I can Pump every so often Rob, do you have a favorite football team? Well, the cornaskers of course What's your opinion of Solana? Heard the magical Eden moved the polygon Really is the future left for sole developers or a stigma of fcx too much They're gonna take a hit but I gotta tell you Like a friend of mine Steven he talks to me. He said, hey, are you Solana for DeFi? No He goes, you know, it's super fast and super cheap the want the problem is that people really hate the fact that You know Solana the head of Solana development again the phone with all the All the note operators and go look reset And that doesn't seem very decentralized. I think that's a problem me personally Right like Charles Hoskins can can do whatever he wants to For codona state pool operators and we're not gonna do what he says just not even when there was the upgrade a couple Wants to go. He's like, we want everybody upgrade and we're like, no, we'll test it And of course, I don't I'm not the technical person Obviously from my stake pool. It's uh, we have a team that deals with that very sharp individuals And they said we're not gonna upgrade until we see some proof and do some testing. That's what it was So I like Cardano speaking of which I'm gonna have Mickey Watkins from World Mobile token on relatively soon So get your questions out tweet at me or send me message and I'll ask Mickey what what you guys got?   So that's pretty much why you have to admit your mistakes and move on very simple Let's see Yeah Vuli says take rules on vacation as Texans was stuck on a highway. That's true That is very true. Can't deny that Ah Tortuga keel diversified holdings of both treasure and lecture. It's a good you can do that I should do that actually I should put it in a tracer. It's all cold storage, but it'll be interesting to find something else Jarkie says no gold or silver. Why not? Why not when the apocalypse comes which is what all the all the goldbugs will tell you why not? Still living in Puerto Rico. Absolutely You don't get those types of trees in Texas Chebo says what do you think about the current privacy coin called? I think it's called midnight I don't know much about it. So I can't really speak on it. Sounds awesome. Ah Dr. Payne and fellow veteran 20 year Air Force retiree. Thank you, sir for your service appreciate you Roger look at your Twitter DMs. Ah the ones that the people that I follow. Yes, but the other ones It's all like if you DM me I'm gonna tell you right now. I'm gonna miss it because I get so much Hello, sir. Can you talk about our? project on your channel and I just and Hello, you know Amanda blah blah blah wants to be your friend So I did I don't really talk about them Yeah, I hate those cookies too and with that John is correct. This is the The the most expensive a green screen you can get right here. It's very tough to do I am in my mom's basement time for meatloaf. I got to get out of here. So look everybody Coming up on an hour. So thanks for hanging out with me. I appreciate it If you like this video give it a thumbs up consider subscribing all the good stuff I mean YouTube sometimes does actually notify people I was wrong, but that is it So thanks so much everybody for stopping by. I'll see you on the next one adios


So, hi guys, my talk is all about going to be all around JavaScript, so how you guys use JavaScript on mobile platforms. So, let's look up to JavaScript, so you guys might be familiar with the word look up, right? You guys are been looking up, I have been looking up your Twitter tweets, so some might be seeing the fan above the ceiling and all. So it's basically an ideology of the firm, so I can't help with that, all right? So you can see some code stuff I have written, some scribbled one. So let's move forward with introduction, hi, I'm Dhruan Rathod. I work at Moorches and front end automation lead at housing.com. So, just being like there are two kinds of JavaScript developers.  So the Nazi ones develop all those frameworks and all, followers just follow them. So I just love to be at the Nazi part of it, because that is the way you get the good reach as what, how JavaScript actually works. So you have to clean up things, you got to create new stuff rather than just attaching the previous created one and just keep coding up. So my introduction itself shouldn't be in English, it should be in JavaScript, right? So yeah, if you can decrypt this one, it's great, you can apply at housing, all right? So this completely makes what I was saying about myself. And my task at housing.com is to pursue everyone to use JavaScript.  So let's do it in Node.js, like I'm Node.js, I should get projects into the Node.js. So I will say them, okay, you guys are doing it in a synchronous way. Let's do it into an asynchronous way, it would be faster. And they will be like Ruby is like Rails is quite good, we have a scaffold, we can do things very easily. Just a command and everything will be created. So my task is that and I love reading JavaScript, not the JavaScript that we read, but under the hood, how the compiler works, how it gets interpreted, how browser is attached to it. So all kind of geeky stuff all around. So I'll be discussing that part as this talk was more aligned towards JS foo. So I removed a lot of geeky parts. I left that with abstracts. So hope you guys like it. Let me, okay, these are my social handlers. If you want to tweet some questions after around the conference, you can, okay? I guess, okay, if one of the great anonymous speaker once said, if you don't start respecting the web, it's going to be doomed. And, okay, that are my initials down there. Okay, so I once said that. Let's move to mobile. So from mobile, what I think is it is a small device with less memory. You have very less memory. You have very less CPU. Like you have very less CPU cycles to do things. Like JavaScript is an abstract part. At application layer where you see that, okay, if I type console.log, blah. It's going to be console.log. But you never think about beneath the layer what is happening. If your code can totally make your app suck. So that are the points that you need to focus. So I am going to discuss those parts today. And less interaction area. Like this is the small screen at which you work. Plus all these guys are doing is every year, they are adding more pixel string like DPIs every year. So it's a trouble for front end mobile developers. Mobile web app developers that you don't see, but it is there. Like, yeah, you have to convert your images to a better resolution. So on mobile, what we guys do is previously we just scale it down and then just put it. So now we have to keep up the resolution of the images, right? On the mobile, on the devices. And sensors and web API, more events, like touch events you have. And web sensors, like web APIs are there for your navigation sensors and everything. So all these stuff clubbing together on the mobile web, it is a good thing, right? But there are consequences, like India is a growing country, right? Here no one won't, everyone dreams to buy an iPhone, but not everyone has an iPhone. We work out at a low edge devices, which works on like, recently I was previously here with Mozilla. So we promoted Firefox OS here, right? So Firefox OS devices are very low end devices. They don't work on much memory. They have 256 MB of RAM and very less RAM, very less CPU. So you don't have much of the CPU cycles to perform things. So if you're going to use that jQuery and everything big, big libraries on the mobile, your app is never going to work on Firefox devices or the similar kind of devices. But what I think is major problem, mobile web should be compact, right? It shouldn't be like whatever you have on the desktop, you just copy paste the whole code, you just add CSS media queries, just shrink it, make it look like there's, okay, this is going to work on mobile. So this is not the way you code your apps. You should be thinking a lot. You should meet with peoples who know things about mobile web. So the good news about from housing, coming from housing is we have moved to mobile first. Now, our first priority is going to be mobile. As you can see, we have changing things like moving user to the app if you come to mobile websites. And we pretty much reform our mobile web. We have changed many things, cleaned our JS codes that were ugly. So we're going to discuss all about that. So let's move. So browser design is basically UI is what you see, the front end, the mobile screen you are seeing at the web. That is UI. Next comes a channel. So basically, let me just put up all of these points. And there you see, there is your JavaScript. So your JavaScript is not going to actually react on the same moment things going to happen on the front end. So basically, your events or everything, your DOM changes, these flow like, sorry, my bad. I shouldn't have done animations. So UI is basically what you see. So that is another library that browsers use for painting your screens. And then they have a channel in between which connects to the actual browser engine. JavaScript is not in C++. It gets interpreted and it gets executed in a different environment. So you're not going to actually hooking that thing directly to your DOM or whatever which is beneath. So above that is JS. So your JS traverse this path to actually make things happen on the UI. We, as front end developers or mobile web developers, we don't think of this perspective. We just code. Who cares about these things? Some of my friends said, who cares about having an O1 complexity of accessing something or an ON of complexity? But it does make sense when you want to create an app that makes sense to the web audience. You're not going to flood the market with shitty apps that doesn't work.  You add a JavaScript jQuery library. Then you have jQuery mobile. Then you have jQuery scroll. Then you have jQuery carousel. And jQuery x, jQuery y, jQuery z. Then you have a backbone. You have Angular. Why all these masks you have to create on mobile? Just keep it simple. You need not to put all those things on to the mobile. It is not made for that purpose. Let's move to actually JavaScript flow works. Whatever you write, how does it actually work? So it obviously compiles. So everyone says it is an interpreter based language. But still, interpreter has to compile, generate the graphs and trees and everything. After compiling, it tags them. Like binary opcodes is basically this clause. How does interpreter is going to understand that? So compiler, what it will do is it will just tag that place, like add a operant there. This is a if clause. It starts and it ends here. Next is interpret. Interpret the code, run through here, whatever you have written. Then execute it previously. Initialize a stack and context variable. That is the most important thing. So it's basically whatever the environment. In JavaScript, every function works in a different way. It's an object. It's a new object whenever you execute a function. So it has to be initialized with its own environment, stack, whatever, x, y, z. You don't have to worry about that. We will come to that later. So how can you optimize your JavaScript on mobile? I'm very much concerned about people using JavaScript very badly on mobile web. So that is the main purpose of my talk here. Why are we not using JavaScript the way it is meant to be? Why are we hooking things up that doesn't make sense on mobile web? So these are places where you can optimize your JavaScript. You can initialize, add the initialize, execution, compile point. Even monkeys know that. Prototypes can help you in building better JavaScript. So we can learn from them why you use JavaScript on mobile. Templating, we all do templating. We create Angular apps, and we do templating. We use React and stuff like that.  So we code whatever we feel like.  So it doesn't make sense when you can actually optimize things, but you're not doing that. So we might end up someday that with the holding, walking all around the street that I can code JavaScript. Just give me some money. So let's start with templating. Templating is basically you have a DOM string. You want to construct a DOM string, like a whole HTML part, with whatever data you have from your model, and you want to print it that on the front end, on the mobile web. So there were many ways of doing it. And previously at housing, what we were doing is we were using Hamel C. So this is what our template looks like.  It's an Hamel C template. So it gets required on the front end. What we do is previously what we used to do is call the API, and let's have the look. Previously, send API request, then JSON parsed the data. So if you have gone to housing.com, we have so many properties to list. So every property has so many fields, like rent, date added, x, y, z. So those are big chunks of JSON data. So on a list of 10 of pagination, like we were not doing pagination previously, but then later on we understand things and we moved on. So previously what we were doing is just calling the API, getting that 60 or 50 of results, and then we were just sending it to the template. JSON parsed that data, pass it to the template, get the DOM string, and attach it to the DOM. So what do you guys think? Is this process makes sense on the mobile? It does on desktop. Does it make sense on mobile? Why do you have to JSON parse the data on the mobile? That big amount of JSON doc you are parsing. Like Douglass Crockford written that thing doesn't mean that on everywhere you are going to use it. So pass it to the template. You saw the template previously, right? That big JS page. So that is basically a string concatenation, ifs, block, x, y, z. So that is creating a string concatenating string and making a big huge DOM string out of that. And then the last part is attach it to the DOM. Then later on, we figured out that this part isn't required. This is not the way of doing things on mobile, right? So we thought let's not make the user pay for it. Let's make it easier for the user to access our web app. So what we did is we just pass a flag to our API saying rendered through. So that is like our API is going to pick that JSON data, parse it, pass it to the Hamilton template, compile the whole DOM string, pass it back to the front end. So basically, it's like removing all those parts. You just have the HTML given back by the API itself. So you just have to do attaching it to it. So this is the output of the API now. Previously, it was like a JSON doc. So with the flag, we fixed that. Let's talk about events. Events are heavy if you haven't like deal with them a lot. How many of you have built canvas-based games on mobile?  And then you have to manage. You have to fire all those callbacks onto it, right? So you have to make it very soft and very compact of the JS part so that it doesn't lag on, like canvas printing and everything doesn't lag. So what makes events heavy? Have you ever thought of it? Like why events are heavy that much? We previously saw that JS doesn't work on the lower end. There are channels through which data passes. So whatever event happens, that happens on the front end, on right on your canvas, not on the JavaScript. JavaScript gets to know that event after a while when a browser tells him, OK, this is the object. These are the nodes. This is the event. Just fire it. So this is how event propagation works. Everyone knows this. Does. Let me explain. Events work in three phases. The first one is the capture phase. So capture phase, basically, the actual event has happened from the top to the bottom. This is basically the flow of event. Event flows from the top to the node at which the event actually happened. So this is one. Second is target phase. Like you will get the event, not before that. After that, whatever you have to do in bubbling phase. So I gave a thought of it, like why should I be worried about so many things? Like it goes to capture, target phase, bubbling phase. I'm going to have this event at the target phase itself, right? Not before that. So how can I fix this thing? It was a weird thing for me to see. Like why? Why I have to do these things? Like why browser is made this way? But there are reasons. Those are smart guys who build it. I'm no one to judge them out. So how does actually events occur? Let me give you a brief. So the front end is basically a canvas. It's not like an HTML tag what you have written. It has been converted. So iskia skia is a library that every browser uses for printing front end. So basically it is a C++-based library which prints those 2D models, 2D boxes on the front end of your browser. So it is on Android also available. So they are ported that too. Now your event has occurred on the canvas, not on the JS. So it has to somehow propagate to the JS part, right? So in between, there comes a channel. So that is the DOM channel, like the canvas to the browser engine channel. What it does is it waits. It listens to whatever canvas is sending back. So whenever we have an event on the canvas, browser listens to it and then pass it back upwards. Then there is one result target. So you guys saw that chart of capturing face, right? So all those are the nodes. So those nodes has to be resolved. Like DOM doesn't knows where the event occurs. It has to somehow figure it out, OK, this is the DOM tree which has been actually had the event occurred on it. So in between, init of event property, these are the C++ functions if you go deeper into the browser's code. So these are the actual function that does occur beneath the hood, which we don't know. And then bailout handlers. Bailout is a concept that I will discuss later on. I'm not going into that. And the last is your handler, because this is how event acts. We guys think that the event is like directly propagating from front end to the JavaScript. So differentiating front end with JavaScript, it is a model on the front end itself of a back end. I guess it has some problem. So let's discuss about it. The faces. All right, sure, sure. Hello, hello. OK, so what we actually see is the JavaScript code that we execute. We don't understand the beneath layer. So I'm here to enlighten a little bit about that. What is beneath happening? So this is what actually happens when your touch event is fired, when your click event is fired, when your drag event is fired. Or all those events are happening on that small scale of device. So every event has a thread running, an observer running behind. So we are basically firing those threads up. So more the events are there, more all those traversals are there, the more memory it is going to eat up on the mobile. So do we have a problem right here? Do you guys think there is a problem in this flow? I once thought that this is a problem. So I went away with a solution. Like events has to do complete cycle. It has to go from capture phase, then to the target phase, then it goes back to the bubbling phase. So you guys might be doing event dot stop propagation. That's it, on the target itself. But still you are doing on the target. You still have the capture phase coming down.  If you have a game on the canvas and you are firing too many events, so that is going to cause mass. If you are going to fire too many things and you are creating objects into that function, you are doing some cool JavaScript stuff into that. It's not going to work for your web app. Trust me, it's not. So why I have to wait for an event to reach my target? Can I do it before? So do not let it bubble. First thought, capture it at the first place. So if I can somehow have my event listener on the window or the body itself and listen to all those events occurring, like what all event handlers I have beneath the body. So top hierarchy event handling and stop the propagation right at the body itself in the capture phase. So we all know the flag. So this is how an event object looks like. Doesn't it looks like so bad to it? Like this event object is sent to every node in the capture phase and then to the target phase, then to the bubbling phase. So it's not going to work, right? This is a big memory thing. Like, so what I thought is let me attach the events at the capture phase. I want to attach an event handler at the capture phase and I want to capture those events right at that moment. I don't want these mess to happen all around. So there we have the capture flag true. Document dot body dot add event listeners or attach event on the IE. So you set the attach capture true. Now, this is the path. This is the whole tree path you will get at the right moment when the event occurs, like when it was going down to the target at the body itself, you will get this. And there is your source element, like at which source this event actually occurred. So you got everything right here, right? Why do we want this to propagate down to the line there? So this is a workaround. Like I'm not saying this is the best idea, but it can help you, some of you guys in developing apps. So you guys might be thinking like, I can have inline events, React.js does it, right? Inline event on XYZ or you can write in HTML also, right? On click div into it, you write on click equals to this. So we read that it has the highest priority, right? The inline event handlers have highest priority, but let me correct you. Capture event listeners have the highest priority. No one will call that inline event handler. And why inline event handlers are mess? Look at this code. This is the source code snippet from the Firefox browser itself. And they clearly mentioned into the comment of their code that mtarget later and compile lazily.  So what it does it keeps that whatever the function name is and it will compile it lazily like, okay, fine. I don't care. I will compile it later when the upper layer gets it. So it is very, very slow. Trust me. It is slower than document like element dot on event handlers. It is slower than that because you have to pick that particular string then you have to look up into whole of your JavaScript. The engine does. You don't have to do it. But engine has to do all these things. So it's like, why? Why I had to do this? Like on click are very bad. Inside the DOM, you never have to do this. So I made a small library at github.com event man. So no racism or feminism or whatever. It's just a name, okay.  Listen on the body tag. I'm listening all the event on the body tag. Now you might, you guys might be wondering like how I'm going to fire those events. Like how I'm going to know that this element at which the event occurred. How I'm going to know that, okay, this is the handler I have to fire. So it works in the similar way the jQuery works. Like you have dollar dot whatever on event or dollar element dot click on click and whatever event handler. So the same way it works. You just tell him, this is the node attach this listener to it. So basically what it does is assign unique ID to each node. Whatever node document node you gives him, he just assign a unique ID to it. And then it saves it into a map. So that later on when we call, we have like a faster execution of all those callbacks. And access the ID and lookup into map, execute the event listener and just stop the propagation. We don't want bubbling to happen. This is a workaround. I'm not saying that this is the best way. So you can actually increase the throughput of your events and how much you can improve is here. So it's a lot, right? This is the sample of thousand events. And jQuery 1.7 took 300 milliseconds to fire all those thousand events. And jQuery 2.1 did a little better. And event man, 33 milliseconds. I was stunned by seeing it, how can it be possible? And then I checked on every browser, every version, it was constant. It was 33 milliseconds, that's it. So that was a huge success for me. Okay, what is wrong in event man? Like till now I haven't coded, like added few more functionalities to it. The first one is I have to write my bubbling phase thing, right? I have to keep on, like these are the nodes that want to listen to the event in the bubble phase. And the next goes, event delegation is hard for me to do. Like jQuery still does in a dirty way. No one has done it like a perfect way. Like when at the runtime you change the DOM, you add few more nodes and you want to attach the event listener to it. So jQuery provide a delegation way, right? Through delegation, you can call those events. Anyone heard of delegation? Like jQuery.delegate, dollar.delegate, okay, few does. So you guys can check out. The use case of delegate is, let's say I have a list, okay? And you are making a XHR call at the back end. You are getting some data and you are just adding that up, okay? So to attach event listener on that, you can use jQuery delegate. So I don't have delegation onto it. Maintaining the sequence is another mess I have to clean up. You guys are welcome to code into it, contribute to that repository so we can make a better event listener library. Let's talk about JS performance. Like where can, like many times developers say is like JIO JavaScript, why doesn't work? Like it's mess creating things in JavaScript. But it's not because we are doing it the wrong way. We're doing it things in the wrong way. Let's have like dot call versus dot apply. Everyone knows dot call is faster, right? How many of know that call is faster than apply? Anyone? Okay, few does. All right, so actually dot call and apply are like calling some function you can call with arguments. So these are the two function, function D and E. So I can call with D dot call and I have to pass all those arguments. In the apply, I have to pass the array of all these arguments. So why call is faster than apply? So I go, I got into deeper into the JavaScript library like V8 engine and all those iron monkey engine and I got this snippet out of it. Like whenever you write D dot call, it's like it converted into an inline thing and it just passes that. You see those three dots written there? Have anyone coded in C language? Right, we all did. So in C, when we have to pass variable number of argument, what we use is like dot, dot, dot, three dots, right? So this is the same code that actually occurs in the JavaScript beneath when you call dot call. So next is let's have a look at this code. Do you think this code is okay? Like let's have a look at the above layer. Does it looks good? Right, it does, but there is a problem. This is an out of scope access. So whenever you access something out of the scope, the JavaScript engine has to bail out from there, go to another, create another stack, push it those things, whatever you are accessing onto it and then execute things. So that is the bad idea of doing things. Another is calling some function, that add some property. Again, this is not going to pay you a lot. What could be a solution is to these things is localizing variables. You need to localize things. Like do it into the this context itself. If you do things in this context, this keyword, everyone knows this, right? So if you do things in this keyword, it doesn't have to bail out, it doesn't have too many things to mess up around. It just execute very fastly. Let's move to another. This is an array in everything. You can read the array values if you want, okay? So accessing keys is optimized. Like accessing these key values or an object are optimized, it takes over complexity to access these things. Maybe this is a bad idea of changing something that is global into a local context. So you are in into some function, into some function, into some function and from there you're changing something that is above the layer. That is a bad idea because it changes the whole path of JavaScript to compile back things. So might be doing it into the global context will solve things. Return should be as the first statement. It optimizes things like the same stack can be used by all other functions. Like the same stack, whatever you're returning is passed to some other function, whatever you have. Ternary operators are fast, very fast. They are faster than if else clauses. If you see, this is the assembly code that looks like this. And I would rather promote you guys to, if you have one liners, then rather use ternary than if else, these are optimized beneath the layer. Don't block the code, please. Don't block it.  Your whole code will block away. And miscellaneous less timers, set interval and all those things, web workers. So set intervals are basically threads, basically get queued into the event. Queue, web workers make things faster. So if you want to do things very quickly into your app, like Canvas printing and everything, do it into web worker if you have something to compute. That will pay you for that. Document or fragment is a lie. Please don't rely on tweet. It is a lie. It's a big lie that has been coming back from these centuries. Never use document or fragment. It's not going to worth you. I will catch you guys later about this because I'm running out of the time, I guess. So maybe this, don't do animation on using JavaScript on mobile. I'm specifically talking about mobile. You're going to burn a lot of memory and a lot of heat will be generated out of your mobile because CPU has to do so many computation on your CSS. So why should you not do this?  Like you don't want to get roasted by these guys for not using the best animation way. Like you can do these things through CSS, right? This is not a good way of doing. Through JS, they are doing those things. It's messy, quite messy. So performance you can optimize by using all these points is around 200%, I can say. Because I have worked on to all those things. I have worked on using web workers, everything beneath, optimizing the JavaScript, converting, templating to the API response itself. So it all paid up a lot. And in housing, we are going to apply all those things. Like we have started and we are moving forward to implement all those things in next few months, I guess. And tips of the day, never mind to scroll events on mobile. Please don't do that. You can always use touch start and touch end. They are beautiful. They don't too much populate event queue. They just send you touch start and the end event, just two events. Lesson on the top most hierarchy, this is optional. I'm not saying that you should use this, but it might pay. Do not bind too many handlers onto events. This is heavy. Like if you have a thousand of listeners onto the same DOM node, then it's going to be lagging like a way too much. JavaScript is single threaded. Have some respect to the JavaScript. So yeah. Thank you guys. Questions? We'll have one question. Sorry, I can't. So you are saying that you'll explain something in the event propagation because it's an important concept. I cannot. Okay, event dot stop propagation. Basically what happened is event dot stop propagation cancels out all the faces. So the moment you call event dot stop propagation, it cancels out the whole path from coming where you were listening to the target, even the bubbling face. So if you capture things on the top most hierarchy on the body itself and you cancel the propagation, so browser will never ever interfere again into that event and that event will be like a stashed out. So event dot stop propagation is a better way if you don't want bubbling faces or all those faces to occur. Like let's say you have a DOM tree having 50 nodes and then onto the 50th node, an event is happening. Browser has to call all around the way to the 50th, then bubble it out all around the 50th. So if you stop the propagation, it cancels out all those faces to the 50th. Even like it will stop at the end edge where you will listen to the event. I guess you can catch him outside for your question. We are running out of time. Thank you very much.


What's good Josh boros back again with another video? So bring it check out Jeff Hardy spare jail time WWE spoilers plans new WWE PLE big bout revealed for WrestleMania 39 and other related news We're gonna check this out man.

It's also check out our new channel wrestle a mere shorts Now let's see the intro and get straight into our first story Our first story looks at Jeff Hardy spare jail and it could be his last chance Atop of today's news is the latest on Jeff Hardy's DUI case a case that's been hanging over him since last June As we'll see it's good news for Jeff Hardy as you won't have to serve any prison time Which is good Hardy entered a no-no contender PLE aka no contest wearing the except the courts verdict But did not admit guilt according to wrestling news is Andrew Ravens. Hardy will also have two years of probation pay 4586 in fines and court fees have two years with the interlocked device and 90-day vehicle impoundment Go to court mandate DUI school or drug rehab program and to community service in addition Hardy's driver's licenses suspended for the next 10 years Damn credited 38 days for the time you served in jail while the case was pending Hardy was arrested in June 2022 for DUI and charged with other offenses The DUI charge a third DUI within 10 years carried a possible sentence of five years in prison It appears that Hardy caught a major break after his attorney file paperwork seeking to have the breath test results Excluded as evidence wrestling news report noted the attorney claimed the Intoxalizer that was used was not inspected by the Florida Highway Patrol the month before Hardy tested with it And that violates a Florida Department of Law enforcement here that the equipment must be inspected every month Here's lawyer good could have continued the case It's unclear whether they would have prevailed a trial as often happens prosecutors prefer to achieve some sort of conviction Rather than lose a case it remains to be seen What's next for Jeff Hardy as far as wrestling goes and whether he can deal with the personal demons that have plagued him throughout his career Should Jeff have gone to jail though? Does he deserve another chance? Let us know in the comments down below Next up. Well, here's the thing man Here's the thing at this point He was given some type of out You know crazy days life is gonna be suspended for ten years He has to do a lot of things It's really up to him. It's up to him at this point if it happens again It's on him now.  This is multiple times that someone's been given a chance and You know they they you know Driving while under influence is never good for anybody. You know I'm saying I want to put this out there I've had my my fair share of moments. I'm not proud of and that's why I don't condone that nor do I Participated that if I know I'm gonna be lit or you know, I've had too much to drink I have somebody take me on my Uber or you know, I said I'll chill You know wait for me to sober up a little bit more before I even think about getting on the road If I know I'm not good I'm not going nowhere or you know someone you know can take me on over home or whatever the case may be You know, it is it's really a dangerous thing So I you know, this is it's kind of a win for him because he doesn't have to you know, go to jail prisons or prison time, but This needs to be the last time we hear about this from Jeff Someone needs to be able to help him Stay on the course because if it happens again, I don't think anyone's gonna have sympathy I think a lot of people have let go of this, you know, having sympathy for him, but if it happens the next time He may have to he he may have to serve some jail time This is one of our childhood heroes and we hate to see it like there like this like him going through this But you know, he's endangering himself and other people out there on the road while under the influence So I'm wishing him, you know A Recovery in the sense of mentally being able to move forward and and learn from this. I hope this doesn't happen again I hope we don't ever have to hear Jeff Hardy's name in this type of situation again Did WWE spoil a major storyline? Did the WWE spoil a major storyline with a recent live event advertisement or fans tuning into the 20th February? Roars saw Sami Zayn ask Kevin Owens to help him take down the bloodline Only for KO to remind Zayn, he told him last year that he's through with Zayn However, a recent ad from Toronto's Coca-Cola Coliseum for the WWE's 4th March live event suggests a reconciliation While the tweet was deleted, it was captured by various sites including Wrestle Ops, which tweeted WWE are advertising for the March 4th live event in Toronto, Canada That will be headlined by Roman Reigns and Solo Sokoa versus Sami Zayn and Kevin Owens This could be a social media marketing mistake as it wouldn't be the first time the WWE's social media department bungled an ad However, we were many fans believing WrestleMania will feature Zayn and Owens teaming on to take the Usos for the undisputed tag team Championship many believe that this is no error. What do you guys think? Was it an error? Let us know in the comments down It was probably error on getting out, but it's gonna happen I mean this is you know, it's part of their way to you know, probably trying to you know Get some hype for that house show because people don't want to see them tag tag team and want to see Roman out there as well So yeah, I definitely see this happening. It's gonna happen. It's just kind of it kind of books itself It makes sense for it to happen that way and below Next up a big bout in the works for WrestleMania 39 the time for a look at a marquee match plan for WrestleMania 39 That being Dominic versus Rey Mysterio in here Universe has been waiting for this one to take place ever since Dominic turned his back on his dad following the events of clash at the castle Joining Rey's rivals the judgment day now Dave Meltzer's reporting in this week's observer that Rey Mysterio versus Dominic Mysterio This hasn't been announced But it has been the plan for months to hold off their first singles match to this show Yeah, the WWE is taking its time building things up for this match taking Papa Ray out of the equation when he moved to Raw where Dominic wrestles to SmackDown That's minimize the interaction between the estranged father and son on WWE television The idea being that Rey would rather walk away than fight his son However, the WWE's vignettes where Dominic crash family functions leading to his arrest last Christmas have kept the conflict in the back of the fans His mind in addition they imply that Dominic attacked Rey Mysterio backstage at the rumble taking him out of the match Dominic recently told Bryon Saxon that it'll be joining Rhea Ripley on the 24th February SmackDown Which will likely start things rolling for Rey versus Dominic There have been rumors of the two fighting in a mask versus hair match However, it's unknown whether the WWE intends to build up on such a match if it intends to book it or wait until down the road Extending what should be a hot program between the two Next up next up I will say this That's gonna be a match of people want to see I'm gonna want to see that you know and honestly Honestly, I don't know how you booked that Pardon me feels like yes Dominic does need to win Dominic I mean you're trying to build he's the future But there's also a part of me that just wants Ray to get a substantial win I just want Ray to get a very substantial win in my opinion. I think that would be a cool moment I don't know it just makes sense from a logical standpoint If you're gonna do father versus son son with realistically beat the father and move forward, you know Solidifying his legacy, so I don't know but they do have a match at mania. I'm all for it Mania main event musings which match will main event WrestleMania on night one While it's a given that Cody versus Roman will headline night two There appeared to be different opinions on the first night Meltzer went over the situation and this week's observer saying there is no decision on the main event past an Internal feeling that Charlotte Flair versus Rhea Ripley right now is the favorite There is a push feeling for sponsors and political reasons after men main evented both nights last year It would be good for a women's match to headline and the feeling Flair versus Ripley is stronger than Bianca Bella versus Oscar for the sport Yeah, there's Usos versus Zayn and Kevin Owens one would think that would be the other favorite Yeah, WrestleMania 30. I ain't got a lot to you Usos versus Kevin Owens and Sami Zayn. I think that would be a great man event for the tag team Titles, I think that'll be the first time ever correct me for wrong. It'll be the first time ever The tag team championships main event in a WrestleMania. I Me personally, I'm okay. What you doing that? I'm okay. What you doing that because of the story That it involves I'm okay. What you doing that if you have Sammy Kevin Owens main event for the tag team championships with the Usos I'm okay with that. I Think that I think I think the crowd will love that match So, I don't know. We'll see what y'all think, you know Do y'all think that should be how night one ends with Sammy versus Sammy and Kevin Owens versus Usos The nine is shaping up to be one of the biggest additions of the showcase of the immortals and having this many potential main event Has to be seen as a positive but should Flair versus Ripley headline WrestleMania night one Let us know in the comments down below Next up a new WWE PLE revealed a big news concerning WWE's PLE schedule for 2023 as Wrestle Comics is confirming a new PLE will debut after WrestleMania 39 If you've been keeping up with the news you'll likely recall rumors WWE was thinking of turning its king of the ring and Queen's crown tournament into a PLE Long time fans know the king of the ring was a WWF pay-per-view for years until the company scrapped it in 2003 occasionally bringing it back for TV And now Thurston is reporting that WWE has two PLEs planned for May Which is backlash booked for 6 May and King of the ring or Queen's crown booked for 28 May It's also believed that WWE is contractually obligated to provide 12 PLEs annually for Peacock So this will make up for the WWE not airing one in March This is interesting news for many reasons. They are contractually obligated. Okay. That makes sense, man We're claiming that it was previously believed that WWE would hold one of its Saudi Arabia shows in May However, that's not the only intriguing aspect of this report Next up a big twist in the Shawn Michaels vs. Grayson Waller storyline Is Shawn Michaels going to wrestle NXT superstar Grayson Waller? Well, the heartbreaking has his hands full running running NXT NXT Superstar Grayson Waller has been making the showstoppers life Easy of the late things have been building up with a black and gold brand teasing that Waller's whining could lead to Mr. WrestleMania stepping back into the ring again However, a recent report from W.R.K.D wrestling which both the story of leaders return to wrought suggests something very different As many fans have speculated the idea of Shawn Michaels forcing Grayson Waller to face off against a debuting Dragon Lee has indeed been discussed This could be a wild way of introducing Dragon Lee who chose to sign with WWE over AEW but hasn't been seen on TV since announcing he was signed with WWE last December Next up is Mercedes money appearing at Forbidden Door 2 Of this speculation the newly crowned IWGP women's champion could show up at the rumored Forbidden Door 2 pay-per-view Mercedes aka former superstar Sasha Banks would be a major addition to the AEW show Look at the news that Forbidden Door 2 is gonna happen last year's collaboration between AEW and New Japan Pro Wrestling was a success The show did good numbers in ticket sales and pay-per-view buy rates a Wrestling Observer figure 4 on lines Ian Carey recently discussed how a cable company may have let the proverbial cat out of the bag about the pay-per-view Spectrum cable have been given away the date for AEWX New Japan Pro Wrestling Forbidden Door 2 The company's pay-per-view listings have the event scheduled for Saturday 24 June 2023 The first Forbidden Door took place Sunday June 26 2023 from the United Center in Chicago It's encouraging news for AEW's collaborative events when New Japan if Forbidden Door 2 is happening There's been speculation over whether New Japan will continue its collaboration with AEW following their change in management at the WWE Assuming Forbidden Door 2 is happening. How does Mercedes play into things? Let's look at a recent story where money teased working with AEW wrestler Kenny Omega Mercedes recently wrote so nice to meet you Kenny Omega until our paths meet again Omega replied our work with New Japan Pro Wrestling isn't quite done yet So I'm sure they will I hear they sometimes do mixed matches now, too As wrestling news speculated this can lead to a mixed tag team match And if this happens it doesn't have to happen at Forbidden Door 2 However, if it does it could be a huge match. Fans will have to wait as Kenny Omega's future in AEW remains unclear Rumour has it that Omega's AEW contract may have already expired with the WWE reportedly interested in signing him Omega could be gone from AEW before Forbidden Door 2 though And finally, a masked wrestler ditching his mask It looks like the end of an era for luchador lince Dorado The current major league wrestling star recently tweeted the shocking statement that I've contemplated this for a while now Possibly five years now for almost two decades. I've been someone. I'm not I've decided this will be my last year masked Question is will I lose it or say effort? This is the real me the 35 year old wrestler currently holds MLF's middleweight championship It's unknown if he'll adopt taking his mask off into a storyline But one would think so given the significance of a mask in lucha tradition But they have at folks the wildest news stories in remission very interesting video man very interesting video Hoping Jeff Hardy continues to you know on the path of recovery getting himself together You know, it's good that he doesn't have to go to jail But once again, this is it in my opinion. I know some people say he's been given too many chances and you can say that You can argue that but he's been given another opportunity to make things, right? I hope he continues to do that and what do y'all think about the main event of night one What do you guys think the match should be should it be Charlotte versus Rhea Ripley or should it be? the Usos versus Sammy and Kevin Owens me personally I would like the Usos Versus Sammy Kevin Owens to be the ending match of night one Because you know it's going to play in tonight too because now the Usos don't have the tag titles no more Now Roman's getting desperate, you know, and maybe it plays into the fact of them splitting up J's I man's scooters I'm done. Maybe Jimmy. He's out. You know saying so it can be interesting We'll see how it plays out man. I'm looking forward to rest of me in this year Let me know what's your thoughts on this on this old situation who's gonna main event night one and the whole Jeff Hardy situation Appreciate our love and support road to 150k and I am still you know, just be the YouTube relationship of the world And also can a clutch would it be me Jimmy? Appreciate your kicking me. See you next one. Peace


It's the changing of the guards at Starbase as booster 8 begins its test campaign and SOS has been causing controversy with incoming Hurricane Ian. This is Monday's Tomorrow Space News. It may seem like a very long time ago now, but it was only seven days ago with B7 firing seven engines, the highest concurrent number of the Starship program so far. With this successful test confirmed by SpaceX, the booster switched around at Starbase with the younger booster 8 being rolled to the launch site and the older booster 7 being taken back to the production site for quote unquote robustness upgrades. Elon later said on Twitter that these upgrades are for full engine-rud isolation. Could this mean that the engines will be receiving the blast shields we saw at McGregor last week? Let me know what you think about that. I certainly think so. It'd make perfect sense tying both these comments together. Elon Musk has also given us an update on his personal timeline for when we could be expecting the orbital flight test. November seems highly likely apparently and to be honest, I feel the same way. November or December launch seems doable depending on the speed that booster 8 goes through its test campaign. If it has any mishaps like B7 thinking squash to transfer, tube and big boom, then it may take a little longer. On this Twitter spree we also received information on the first Cape Canaveral launches of Starship which is super exciting. Elon suspects Q2 of 2023, with the hardware being shipped from the port of Brownsville to most likely the turning basin next to the LC39 press site. Not Starships being built at Roberts Road. Speaking of the orbital flight test, the ship currently slated to perform that mission. Number 24 has had its stunning Pes dispenser door welded shut with this cover. Now we don't have any official word why but it's being speculated that trying to deploy Starlink V2s on the test flights may have been a bit too ambitious and rather than try and remove the bay potentially harming the structural integrity of the vehicle it was just easier to weld it shut. We do know that this isn't the end of the Pes dispenser though, it was just a short while later, Ship 27 was having its Starlink rack lowered into its payload bay rings. Moving to GSE, the orbital launch mat has been seeing some plumbing upgrades over the last few weeks with a brand new water daily system being installed. The full system was tested for the first time on Thursday. The mist also has the secondary purpose of making some lovely rainbows. It's not just Starship that SpaceX has been testing but Starlink as well with the first aviation partner that they announced, JSX. On a flight between Burbank and San Jose the satellite interconnection was tested with a speed of over 100 megabits per second recorded which is over double what I get at zero feet, let alone 30,000. Hopefully working tests like this will encourage other airlines to join the Starlink network as although JSX and Hawaiian combined serve a lot of customers having airlines such as American or Delta on board would give many more customers a much better airborne internet experience. Also, fingers crossed, having satellite internet become more mainstream will also reduce the price for airborne internet. Wednesday's tanking test was the most successful test of the entire SLS stack since it first rolled out for the first wet dress rehearsal. All the primary and secondary objectives were met and although there was still a bit of leaky hydrogen it was a massive improvement over the issues faced during the previous launch attempts. There is a lot of hope that the September 27th launch attempt would be able to go ahead after the Space Force granted a waiver allowing SLS to fly with its pre-existing flight termination system batteries. However, Mother Nature has decided that the 27th is not the wonderful launch window that we want it to be. Due to the inaccuracy that will naturally exist in forecasting big storms, NASA kept pushing the decisions until they had better data so they knew they were making the best call possible. On Saturday, they officially confirmed that the September 27th launch attempt had been waived off but they weren't certain on whether or not SLS would roll back to the VAB. On the surface, deciding whether to roll back or not may just seem like a mundane thing but the process prior and the implications of a rollback make the decision even harder. Firstly, SLS has to be disconnected from LC-39B which is a long process then the crawler has to roll under the mobile launcher, pick up the rocket and then spend 10 hours taking it back to the VAB. Once the storm has passed the flight termination batteries would need to be replaced which would basically knock off an October attempt leaving us with November as the next launch opportunity for Artemis 1. Or NASA could leave SLS on the pad to ride out with the October 2nd launch opportunity still alive and well. So, unsurprisingly, NASA was taking their time. For the safety of their personnel, however, the preparations for a rollback were taking place so the process of disconnecting SLS from 39B would be as quick as possible if the call was to be made. Most notably, on Sunday afternoon we saw the crawler being moved under the mobile launcher. Sunday night came and the decision was announced. NASA would be waiting until Monday to make another decision. At the time of writing, there is still no final decision. Or at least there wasn't. Because NASA is fantastic with their timing, the Monday announcement was made the second I stopped recording my piece to camera. SLS will be returning to the VAB with first motion targeted for 11pm eastern time tonight. Last week, we had Ariane Space with Suzy and this week we have Rocket Lab with their not a capsule announcement. Seriously guys, they're just looking into it, promise. Based on the scale to what appears to be the US segment of the International Space Station, it looks like a similar size to Crew Dragon with a separate cargo section maybe beyond the silver seam, but that is pure speculation. That not an announcement came alongside many other Neutron updates at their Investor Day 2022 event in New York City. The major design for the first stage of the rocket is now complete, with the nine Archimedes engines now intended instead of just seven. The same can be said for the second stage, although that only has one Archimedes engine for the final push to orbit. The faring design of Neutron has also been simplified, moving from a full-petal design to just two halves which open up. Speaking of the Archimedes engine, we have some new data on that as well. The sea level engines on the first stage will each be capable of 734 kN of thrust with a specific impulse of 329 seconds. For comparison to SpaceX's latest version of the Merlin, which powers the Falcon 9, which is pretty much Rocket Lab's main rival with Neutron, that has a maximum thrust of 845 kN with a specific impulse of 282 seconds. Rocket Lab also announced that they'd be testing the Archimedes engine at NASA's Stennis Space Centre in Mississippi on the A3 test stand. This stand started construction in 2007 and it was initially designed for testing of the J2X engine, which would have been used on the Ares family of rockets for the constellation program. With the cancellation of that, however, A3 no longer served a purpose. It does now however. We also had this render released, which is what Rocket Lab thinks launch-powered two at the Mid-Atlantic regional spaceports in Virginia will look like. Most interestingly though, what do we have here? Could this be a Rocket Lab drone ship? Peter Beck said previously that marine assets were very expensive, but he's eaten his hat before. Literally. And what's this figure here? 15 tonnes expendable, 8 tonnes return to launch site, but what does 13 tonnes reusable mean? Could we be seeing Rocket Lab marine assets after all? This is a very interesting topic, so I'd be very interested to see what you lot think in the comments down below and also how many more hats Peter should eat if this does come to fruition. And finally, before we get into some launches, the Double Asteroid Redirection Test, or DART, is scheduled for impact with Dimorphos, affectionately called Diddymoon, at 2314 UTC today, September 26th. On the 11th of September, Lissia Cube, an Italian Cube sat riding alongside DART, was released from the primary payload. It'll be following DART as it approaches Dimorphos, staying at a safe 55km distance, giving us a third-person perspective on the impact. Diddymos and Dimorphos is a binary asteroid system with the latter orbiting around the former. The aim of this collision is to slow the orbit of Dimorphos, making it smaller. The collision is expected to slow Dimorphos' orbit by only 0.4mm per second, but over the course of several weeks, this will become even more apparent, eventually ending up with an orbital period, how long it takes to orbit the host body 10 minutes shorter than what it is currently. It's a busy week for traffic starting off with Yunhai 103. This environmental satellite launched at 2315 UTC on Tuesday, the 20th of September, from launch Area 4 at the Zhiyuquan Satellite Launch Center in China. As usual with Chinese launches, that's all we know. Next up, it's time for another ISS crew. Soyuz MS-22 launched at 1354 UTC on September 21st, from Site-31-6 at the Baikonur Cosmodrome in Kazakhstan. Commanding the mission is Serkei Prokopyev, with Flight Engineer 1 Dimitri Patelin and Flight Engineer 2 Francisco Rubio alongside him. Rubio is flying on this mission from NASA as a part of the Seed Swap Agreement between the US Agency and Roscosmos. Following a classic Soyuz speedrun, MS-22 docked to the airport on the Rassvet module at 1706 UTC just over three hours after launch. This mission is expected to last for six months, with the planned end of mission date currently set as the 28th of March next year. This next launch is the end of an era, as at 2225 UTC, on September 24th, we witnessed the last ever Delta launch from Vandenberg. Specifically for this flight, NROL-91, it was the beast that is the last of the deltas, the self-firelighting Delta IV Heavy. The host to this magnificent sight was Space Launch Complex 6, and as this was a secret mission for the National Reconnaissance Office, our knowledge of this mission ends there. It is suspected that the payload is Keyhole 11, a satellite which is similar to the Hubble Space Telescope, but instead of looking at pretty stars and galaxies, it looks at the Earth. Back to China we go for a launch of the Kuai Xiao 1A rocket. This mainly solid fuel rocket carried Cheyenne 14 and Cheyenne 15 from the Tianan Satellite Launch Center. A common theme for this week as these two payloads were classified government satellites. Of course, we have our standard Starlink launch, which we do now pretty much every week. Launching just after the last Vandenberg Delta at 2332 UTC from Slik 40 at the Cape Canaveral Space Force Station, Group 435 had 52 satellites headed for their initial 337x232km 53.22degrees low Earth orbits.  What's coming up over the next few days? An unknown payload on a Long March 2D from China, then potentially the maiden flight of the Zuka 2 rocket, which would make it the first methane-powered rocket to orbit, assuming it gets that far. Fireflies return to flight with To the Black from Vandenberg, Slik 2 West and Atlas V in the 531 configuration on Friday from the Cape, with a potential Starlink flight an hour afterwards as well.

that we have now one year after the pandemic had started, several effective vaccines available and already approved in Europe. And this is a great achievement of translational and clinical research to get in this short period of time, although it seems so long for all of us. This output that we have now the possibility to vaccinate the people all over the world and here in Europe after approval of the vaccines, now for vaccines by the European Medical Agency. The principle of showing that a vaccine is effective is that you vaccinate against placebo, a population, and then you see under the daily circumstances of this specific population, how many infections you can document and how severe those infections are. And this is the principle the vaccines were based on. Due to the shortness of time, the vaccines were evaluated in healthy volunteers and those persons were not necessarily patients. Regarding the study population, we have to claim that only a minority of patients, for example, 3% of those who were vaccinated in the first Biontech Pfizer trial had a cancer history. However, we have a lot of experience for vaccinations in cancer and especially in myeloma patients. And we know that myeloma leads to an immunosuppression and that the probability of severe infections per se is higher than in non-myeloma affected patients. And we know very well how effective pneumococcal and influenza vaccinations are for myeloma patients and how important. We know that in immunosuppressed patients, also in myeloma patients, there are sometimes infections despite the vaccination. However, for influenza, for example, we know that those infections then have a milder cause normally and so that the vaccine cannot prevent from being infected but can prevent effectively still for having a severe disease cause for the need of mechanical ventilation and so on. And we translate this experience very clearly to the now available COVID vaccines. The International Myeloma Society, the International Myeloma Working Group, the European Hematological Association and all country specific hematologic and oncology associations clearly stated a yes for all myeloma patients being vaccinated against COVID. And this is a clear yes and a clear yes for all approved vaccines. The vaccines approved are different, different in the basis we have two mRNA vaccines, the Biontech Pfizer and the Moderna vaccine and we have two protein-based vaccinations, the AstraZeneca and the Johnson & Johnson vaccine. All have advantages and probably also disadvantage but they all are very effective in protecting from infection, from being infectious and especially having a severe disease cause so with the need of intensive care or mechanical ventilation or even ultimately that COVID is leading to them. We know that myeloma patients have a higher risk for severe COVID infections and disease courses and that this accounts especially for patients with the very active myeloma disease. So that our clear recommendation is that any single myeloma patients should receive as soon as possible and as soon as it is available for each individual patient a vaccination against COVID and we recommend any single approved vaccine and we hope that the infrastructures will be providing the vaccine now very, very fast to our patients at need.
