What is going on guys welcome back to the channel critical overlord here So we have some news on the upcoming Chucky TV series man Diane Mancini took to Twitter to announce a couple of things over the past couple of days specifically April Fools We got a first look at another teaser We have a a little bit of a more of a confirmation that it's coming out this fall as it was slated to come out In the initial teaser that came out last summer Diane Mancini took to Twitter to announce the production was underway for the new Chucky TV series Which we know is based on the child's play franchise and like I said before a few new teasers have been released We saw the animatronics that they're looking to use in the upcoming TV series So that should make all of us excited for those of us those of us who love the animatronics and love Those practical effects and not the overuse of CGI so we'll see how that all comes across on screen He also revealed the first episode title in this little tweet here that he tweeted on April Fools The first title or the first episode title the pilot episode title is death by misadventure now. What does that mean? Obviously it means that there's gonna be a death in the pilot episode. I don't see it being any other way I don't see it meaning anything else other than that that there's gonna be a death in the pilot episode We're gonna start off pretty strong gonna end on an emotional note. There's gonna make us very excited for what's going to come in episodes 2 3 4 5 6 7 8 9 I think this is supposed to be a 10 episode season or series at least so death by misadventure Someone's gonna die in the pilot episode of this Chucky TV series. That's really all that means We did find out some some news regarding two new cast members who are going to be playing a role or roles in this new Chucky TV series and of course Apparently now also have Confirmation who Devon saw was going to be playing in the show but starting off with Lexa doig She is gonna start as Aunt Marie Weber who is married to Logan. I'll talk about Logan in a second now Lexa is from Jason X if I'm not mistaken She starred in Jason X and she's basically her character described as being held to an unrealistic standard by her husband So she has a dark secret So I'm gonna go out and let me say this dark secret that she's cheating on her husband Do those high standards and she's having an affair with someone else and then we have another actress who has joined the fray She's going to be playing mayor Michelle Cross. This actress is Barbara Allen Woods She's going to star in the Chucky TV series as the mayor Michelle Cross and her character is being described as being interested in maintaining hack and sack safe image And is concerned for her to her two children Lexi and Caroline now a fun fact apparently the actress who plays Lexi That is the real-life daughter form Barbara Allen Woods. So that's a little fun dynamic their actual mother and daughter duo So again, she's described as being interested in maintaining hack and sack safe safe image and then going back to Logan really quick Because remember Bree Weber who is again played by Lexa doig. She's married to Logan Logan is basically I guess, of course the husband of Aunt Bree so this is who Devin Sawyer is apparently going to be playing and they're the relatives of Jake Weber who you know is going to be portrayed by Zachary Arthur our titular main character for the upcoming Chucky TV series and I'll just share my thoughts on who I would say is going to die knowing that our our lead character Jake is struggling with coming out. He recently lost his mother lives in the single-parent household father probably has some type of type of issues that he's dealing with some personal demons that he struggles with probably connected to his wife's demise so I'm gonna go out and say that Jake's dad is gonna die in the pilot episode and he'll end up living with his aunt uncle and that cousin that he And that cousin that he has the other kid that was mentioned previously in my other video He is gonna end up dying. I'm just gonna say that that's my prediction Jake's dad will end up dying and he'll go live with his aunt Bree and his uncle Logan, I guess so Devin Sawyer, I also just want to throw it out. I still think this is just a theory of mine I think Devin Sawyer is gonna be playing Jake's dad, too I don't know why I feel like I feel like Devin Sawyer is gonna be playing a set of twins I just have that theory Like we already know Zachary Arthur. He'll be starring is Jake Weber the main character. He's 14 years old He's the one that's gonna come across this Chucky doll at a yard sale And then of course mayhem will ensue we'll meet these kids at his school who apparently will of course come in They'll come into the they'll cross paths with Chucky for messing with Jake with just things that we can safely assume Is what's gonna happen in this TV series Jake is gonna be attached to a lot of stuff And then we also saw a look at the animatronic as you see here sci-fi tweeted out something to confirm Or just to tease that the Chucky TV series would be coming this fall later this year on the USA network and the sci-fi network And this animatronic looks pretty cool makes me excited can't wait to see what they do and How they implement the more practical effects here over CGI CGI's Not to say the CGI of course will not be here I think they'll use some aspects of CGI for certain moments, but Always love animatronics always love to see them going for those going for those practical effects over the overuse of the CGI So I'm really excited for this Chucky TV series really excited to see what are the cast members are going to be announced like I've Mentioned before it's not official. These are gonna just rumors that have been told to me Barbara Crampton is apparently gonna be playing Charles Lee Ray's mother So we'll see how true that ends up being if that becomes official because we keep getting cast announcements So we'll see what happens there, but we now know that we have two new actresses We have a former Jason X co-star or former Jason X. She was actually the lead one of the leads She was in the very beginning when she got stuck frozen with Jason And then we have our mayor of Hackensack Hackensack, New Jersey is again the town that we've heard about throughout the child's play franchise So I guess this is where the series is gonna be set it It's gonna be set in Hackensack, New Jersey Charles Lee Ray's birth town and we'll of course learn things about his childhood Learn all these other dark secrets. We know he has His enemies that'll be coming to town. I made a video already talking about the fact that Fiona dwarf We'll be back to be prize her role as Nika or to reprise her role as Nika rather Whether or not she'll be possessed by Chucky still because we know at the end of culture Chucky Since this series is gonna be set after the events of culture Chucky and set in the same universe Well, it'll be interesting to see if she's still possessed by Chucky or if they just kind of retcon that or if they have some type of Explanation as to why that's no longer the case anymore because we know again Chucky as song as we saw in culture Chucky He has found a way to split his soul into multiple fragments and he's got it in this doll that doll That doll over there this doll just I kind of thought that was Person I thought it was ridiculous still very enjoyable overall as a film I just thought it was a step in the wrong direction compared to what curse of Chucky had to offer so hopefully We'll see what they have to do here with going when they're trying to go back to the roots of what made that original film So iconic but let me know what you guys think about all these details down in the comment section below If you haven't already make sure you subscribe turn on post notification numbers of video in the description I have links house all my social media accounts on Facebook Twitter and Instagram You can message me there, of course, let me know is any movies news or views you'd like We just like me to cover in the future without it in my guys I will see you in the next video and go ahead and leave your comment Let him know if you're excited about the Chucky TV series. What do you think is going to happen? Who do you think is going to be in this TV series as well?


Hello everyone, my name is Nona Chith Phasabath. I am 16 years old and I am Cambodian in La Oshun. Today I decided to share a piece of me that I will always be proud of. It all started with the Khmer Rouge around 1968. The Khmer Rouge was a communist party that started the Cambodian genocide. Families were forced to work under them. If anyone retaliated, they would be severely punished. They were given small rations of food. If anyone tried to steal more rations, they would also be either killed or punished. But how this connects to me is because of my grandparents, my grandpa and my grandmother. In Cambodian, we call grandpa's ta and call our grandmothers yai. During the genocide, my grandfather fought in it. He was a refugee. My grandfather managed to escape from Cambodia with my grandmother with a few of his siblings. One dead and one missing. My grandparents soon started moving toward Thailand and had their first child, my uncle. Along the way, they had more children and told they had five kids. The third one being my mother. They had my mother here in California. If my grandparents didn't escape, honestly, I don't think I would be where I am today. Thanks to them, my mom would have probably never met my father thus not being able to have me. I'm so grateful to have such a strong and loving mother. This family is not perfect, but yet nothing in life honestly is. Either way, I still love being a part of it and I can't imagine being without it. Because of these things, my family has endured. I am the person that I am today. I am the first great-granddaughter. I am the oldest amongst my cousins and my siblings. I am an artist. I am Winona Chit Phasaba. Thank you for watching!


Chipotle and the reports of Neurovirus at one of its restaurants. You know, this is one of the situations where enough time had been put between the initial instances and back in 2015 and now that Chipotle, I think, could have really been a very up-stock and now it's going to be another 18 months and that's just sometimes what happens. This is a very unfortunate incident. It could happen to any restaurant chain as any of the restaurateurs would tell you. Chipotle's now off the radar screen for another 18 months.


First of all, I want to say two things. First of all, I'm a really crappy presenter when it comes to making presentations. So I'm trying to cheat using Prezi, so if you get, like, motion sickness, it's all on me. Next thing is that this is a quite difficult or unexpected setting for me, because I think that I'm not really an expert in business or marketing stuff. And every time I'm supposed to be at a venue, which mainly consists of peer people or business people or marketing people, it's kind of difficult for me. But then this summer I read an article about the Swedish social web camp. Have you heard about that? Like this web hike for people that like internet. Which is, I've been there once. It was a strange situation. But this year in this article, there was a great quote by the founder, Thomas Venström. He was asked what he hoped that was going to be discussed on this year's camp. And I was expecting an answer like, latest in e-business or the click-through rate in our business model or something, stuff like that. But he answered that he was hoping that there were supposed to be more discussions on the FRA law, the NSA surveillance, the Snowden leaks. And that really changed my mind, because that made me understand, or I mean, this wasn't real news, but it was really glad news to hear that people that are interested in e-marketing, social innovation or entrepreneurship also have the capacity to discuss stuff that I think is important. So that's why I'm here. My presentation is called, in the world of technology, we need to hack it all. But it's really about that knowledge about technology also includes a responsibility to share that knowledge in order to understand the world. I'm an internet researcher at the Lund University Internet Institute. It's a small institute connected to Lund University, which is located in Lanskrona, at the Citadel in Lanskrona. This is a great setting for research, of course. But it's also fascinating to be in a historical context. This is a medieval castle with the cannons and like it's a fortress. And we're researching the future together. That's quite interesting. If you're anywhere close, I'm suggesting a visit at the Citadel. Among the stuff that we do is to research like file sharing stuff, illegal things online. Why are people considering internet zone without laws, for instance? And that is also both when it comes to users and when it comes to governments. Why is internet zone that's considered to be... You can do whatever you want there. So we have researched the pirate bay, for instance. We're also quite common when it comes to being an expert in stuff, getting back to Lina's presentation. This is from like the news show Breaking News of Wood Philip and Frederick, when I'm supposed to know something about the Iranian Internets, which I happen to know and I will come back to that. More about me. I'm not only an internet researcher, I'm also an internet activist, which means that I'm trying to do good things online and also good things for the internet. This gets back to my young days. In 1994, I started using IRC, Chat Protocol. And I started to hack Nazi chat channels. That was my hobby. Because, well, being an immigrant, I was targeted as a non-Swed quite early and I thought that in my arena, I need to do something. And internet was my arena even back then, so I started to hack stuff. I also started to climb threes. This is a really, yeah, Instagram moment kind of, yeah. This is important, not only because we tried to save the forest, a small forest in Uppsala where I lived. We failed miserably.  But the interesting thing was that we used the internet to mobilize the protests. And this is like 97, 98 maybe, quite early. But we used internet news, newsletters and email chains to try to gather people to climb the trees with us. Fail, but was fun and interesting. Later, I was in Piratbyron, founded the anti-copper-right organization Piratbyron, promoting piracy, promoting all stuff that was important for me back then. Namely, to keep information free online. This is from an interview in Swedish TV where the subtitles are not correct, but fun. And later on, that knowledge was focused to speak at venues in different sites to explain how can the internet community be used, or the understanding of the internet community be used to also understand the politics of the internet and also how this is changing our future. Today, this is my short schedule. I'm going to take you back, back then, over there. Then back here, because we're here now. And also discuss what to do with the stuff that we know together. And then a question in Q&A. So back then, this is not Sweden, this is not internet, this is Prague, 1968. The government of Czechoslovakia was being overthrown by the Russian army from Moscow. Why? Well, because they demanded some kind of democracy within the communist sector of Europe. This is interesting, not just because it's an interesting fact that this happened quite close to us, but also because my father back then had moved to Sweden and was working from a seller in Gothenburg producing dissident material that was smuggled into Czechoslovakia trying to change the system. Using the technologies that were present back then, like printing presses, like old cars, they smuggled books and literature, pamphlets, articles over the border to Czechoslovakia where the information wasn't allowed to exist, trying to influence people in order to get more democracy. Some 30 years later, 40 maybe, this is the Iranian elections in 2009. Kind of the same thing happened. People of Iran wanted something else than the things that they had. They wanted democracy. They got on the streets, protested and got squashed by the regime in Iran. Printing presses weren't really that important back then now, but the internet was. So the Iranian regime started to close down internet sites, started to censor the internet, started to make it hard for people to get in touch with information about the actual situation. Now me and my friends, not in Iran, but in a seller in not Gothenburg, but still in Sweden, started to discuss how could we do this, get the situation in Iran to get a little bit better, but by using the knowledge that we had. So me and a lot of my friends and other groups along the internet started to setting up proxy sites, setting up mirrors of sites that were censored in Iran. All the things that we could do from our home in order to get some more possibilities for democracy to grow in Iran. Of course, I mean, the struggle was in Iran, not on the internet, but still by using quite easy access technology here, we could do some, we could make a change for people in Iran. And this is especially interesting as a case because the regime in Iran told like international media that their actions against the free information were fair because they used the same kind of legislation that we used in Europe. When they started to censor stuff in Iran, they claimed that we do it in Europe as well, which we do. But here we have a legislation, here in Sweden we have a system for banning child pornography sites. In France, we have a system for banning fake medicines, for instance. In Spain, there's a ban against illegal gaming sites. In Iran, there's a ban upon oppositional or dissident media. Same systems, different content. They started to surveil and track people in Iran. They claimed that we did the same things in Sweden or in Europe, which we do. We have data retention in Sweden and Europe, which means that someone is watching us. Someone is interested in what we are doing and when and with who. But on different grounds, of course. I mean, here it's terrorism. But in Iran, this is terrorism. And I think that there are many connections that are meant and really important to be made between our communities. This is Sweden, of course. We have data retention. This is just a short quick start to internet regulation. Data retention. It's supposed to surveil or make it possible to survey people in order to understand who is doing what, with when and who. So there's a system gathering information about which calls we make to who we were making them and where we are, when we are making them. Supposed to be an counter-terrorist legislation, but happened to be devolved since Swedish legislation changed the setting of the data retention in order to make it easier to keep data. So now it's only you need to be a suspect, a suspect for a crime that can give up to six months in jail to be a suspect for data retention, which is most of the crimes in Sweden, which makes all of us potential criminals, if we drive too fast or what it could be. The more known FRA law, which is supposed to surveil the traffic that comes in and out of Sweden that passes over Swedish borders, okay, fair enough. But the problem is that internet doesn't see any borders. So traffic that comes through Sweden could be even Swedish traffic because we use international sites or services. Also, this was hardly regulated in the FRA law. So this was meant to be a law or a possibility for only the defense intelligence in order to spot threats against Sweden. But it happened to be a fact that quite soon after the law, the Swedish police was interested in getting the data from this law to get the data of the information that the FRA was gathering. And IPRED, for instance, which is a file sharing law, which is meant to kill piracy kind of by making it easier for companies and rights holders to get information about who's file sharing. It's supposed to connect an IP address. I mean, the personal number of a computer to a physical person, which it doesn't because the IP address could name the connection, for instance, but not the person actually using the computer. So in Sweden, we have a couple of laws that makes it easier for police, for intelligence, even for companies to track our usage of the internet. And the same laws are used in other countries in order to put the repression on democracy activists. So what? Yeah, OK. We have a decent, I mean, we have regulations and legislations in Sweden, but we could claim that Sweden is a democracy, so we shouldn't be afraid. But then something happened this spring. You know this guy, right? I mean, this is a Snowden room. So I mean, I think that we all know Snowden. Suddenly, a couple of leaks came from the NSA, from the American intelligence, claiming that almost all the international web services that we use as common users give stuff, give information to the American intelligence. It was all from email, chat, videos. Everything was gathered and somehow transferred to databases that belonged to the NSA. It did get worse, though. Suddenly, NSA claimed to track the internet, like the overall internet, not just from the services, but also the internet as a whole, even more than Google, which we think knows all about internet. Then the UK intelligence suddenly happened to, according to leaks, to tap into the internet fibers. I mean, the main broadband connections of the world. And they tap it directly into them to collect information about stuff that they think is important. But we don't know what it is. And then further on, it came as like a newsflash that NSA and the UK intelligence actually cooperate. Maybe we're the FRA as well. We don't know that. And this is a bit strange because, I mean, we should know that this. This shouldn't be a surprise for us. We should know that these things happen. But it gets worse. Here's a news clip from like the day before. There are apparently trash bins in London collecting Wi-Fi information about people passing by them. I don't know about this. Really strange. But we as a tech community in a broad sense, people that understand tech should understand that this is a bad thing. So when we see this, we shouldn't just like think that, oh, this is a bit bad. We should also express our feelings and explain for people that don't know about this, then don't know the consequences of trash bins collecting our personal data and explain it to people that this is not really good. As a technical community, we should understand that stuff like this, therefore the spy, therefore the boss spies on employees. This is quite common in Sweden that bosses or companies want to know what their employees do online during work hours. We should understand that this is only like another way of putting the same kind of surveillance that we see on bigger issues and also in Iran in, for instance, and other less democratic countries. This is an ad from a newspaper just a year ago. As a tech community, we should stand up and say that this is not really a good thing. It's not really a good thing to promote a service that expressively want to track your wife. They had other ads claiming to track their kids, for instance, but the logic is the same. And I think it's quite important that we start to think about not only what we can do without technologies, we can build magical business sites, of course. We can build very intuitive services for getting the cheapest sushi or making it possible to use your frequent flyer points in airlines for something fun. But we should also know that the knowledge that we have is something that we could use to understand regulations, legislation, democracy, politics, and we can actually use that in order to change the world a bit. So I have some kind of conclusion of my talk here. And I really want people that have, like the slightest understanding of technology, and I include the people in this room for that, of course, to use that knowledge to explain to people that maybe don't have or don't have the possibility to learn about technology. What's actually happening? Because we live in a society that is more and more based on technology. The good parts and the bad parts, of course. But we need to translate that into human speak to get people to understand how that relates to them. For instance, it's not a good idea to have a system or to promote a system that tracks your wife because that could be an issue in domestic cases, except of the bad wording of tracking your wife. It's not a good idea to encourage a company to spy on its employees because that also encourages people to do stuff, to hide what they are doing, and also to maybe feel bad about getting to work which is a good, bad thing. It's not a good idea to install parent filters on your child's computers because if you do that, you will have no possibility to know what they're actually doing because they will go into hiding. So you have no possibility to talk about bad things as well. And, of course, we need to talk about the fact that we have regulations and legislations that are quite intrusive and that can sound sane in Sweden because we claim it's counter-terrorism or something. But in other parts of the world, it's not counter-terrorism. It's counter-democracy. And that's a problem. Thanks.


the next question is from Mo strength gains. You've ranked the big lifts a few times. What would you consider the top five accessory movements outside of a squat or deadlift variation overhead press and bench press? I would have to put a row in there. I think a barbell row or a dumbbell row. So there's one is a very, very important exercise. I'll do one more and I'll leave this one. I think you guys will probably guess to split stance squat variations. Well, I mean, that's a squat variation. Yeah. Right. I mean, that's a Bulgarian split squat is a squat, squat variation. Would you see a lunges part of the variation? That's what I mean. I think we could put lunch because you have that back leg. It's stabilizing differently. I think it's a different exercise. Yeah, I would say that lunging or Bulgarian or back step lunge or something like that has got to be up there. So there's two right there. So what do you guys think for the other three? Yeah.  You don't see that on there. That's not bad. Pull up would definitely give you that. I like pull up for sure there. You know what's hard about this is that a lot of accessory movements are very similar as far as how I would value them, right? You have the big core lifts that we talk about so much and we rank and we say are so valuable. And then I kind of feel like all the rest of them are very debatable and like, well, would you put this one above that one or this one? It's hard for me to list what I think is the next. Because preferably, I would also throw in a farmer carries just because of the overall value of what that brings in terms of loading of weight, but also reinforcing good posture. I could pretty much plug and play that in a lot of different types of programs. I could see that.  Very functional.  I love dip because we already did two pulls, right? So we did the row and then the pull up. So I can get down with that. I love the dip for your push. Yeah, because I was trying to give other push exercises. That's not a variation of the overhead press or the bench press. Yeah, I was seeing the farmer carry for the deadlift, you know, like in terms of just holding or just stabilizing. Overhead carries and maybe trying to think of something that would be that's very valuable. Yeah, that's an exercise. So we got the dip. We have the row. We have the pull up. We have farmer carry, farmer carry and overhead carries. Overhead carries are pretty are pretty good. What about like chopping like rotational stuff? You know, in terms of like like a med ball toss or something like it. I mean, it's again, this is an accessory that's it's not easily a program. Why we're over here fumbling all over right now. I want to point out that this is the that's the point, right? That those those top ranked exercises themselves, somebody can get in the most amazing shape and never move outside of them. And the best thing you can do after you move outside of them is all the variations of those movements. Yeah. And then we can get into this debate of all these other secondary movements or accessory movements that are are great. Those are and I'm not saying these are all bad exercise. I'm just saying that when you compare them to the big five, there's so many variations within the big five. Well, that's like the common subsect is what you do is you find like the, you know, the other versions of the squats, the other versions of the deadlifts, you know, like the to implement in the programming as far as like your second tier, while putting it together. After that, it's like, Okay, so now what are we actually trying to do to add to adapt towards? I mean, would a chest fly be in here? You know what? I'll say this. Let's imagine this is a step up. So imagine this is a routine, right? You're designing a workout plan for someone. Yeah. And we have to pick an exercise for the each major muscle group. We did.  Like that would round this whole thing out and include a very functional stabilization component, some core. Oh, I was thinking of, okay, what would I do if I was going to use the next best accessory movements? And I want to attack the entire body like I want to hit a chest exercise, shoulder, arms, back, legs, but I can't use the five big what am I for big, right? Yeah, four or five. In this case, they use five. What what what would I do? And I the dip can argue you can argue is your chest, right? Right. Right. Just shoulders, yes, back, back biceps and rows that that goes there. Legs, we're going to say what you're going to say step ups and lunges, lunges, squats, we're already there, right? So lunges give you that other component. Okay. So let's see, we don't have like a like a functional stabilization type. I mean, farmer carries are really good for that. You know what would be good? I mean, I think I think that the next one the next one we can add is debatable, right? I would love to see the comments after this video because I know Andrew, you know, puts these videos together. I'd like to see in the comments what people think that next exercise should be. Yeah, there's really not a wrong answer here. And I think I can argue almost any other accessory movement. Let's see what you guys think.


In philosophy, the matter of personal identity deals with such questions as, what makes it true that a person at one time is the same thing as a person at another time? Or what kinds of things are we persons? Generally, personal identity is the unique numerical identity of a person in the course of time. That is, the necessary and sufficient conditions under which a person at one time and a person at another time can be said to be the same person, persisting through time. In contemporary metaphysics, the matter of personal identity is referred to as the diachronic problem of personal identity. The synchronic problem concerns the question of what features and traits characterize a person at a given time. In continental philosophy and in analytic philosophy, synchoritude the nature of identity is common. Continental philosophy deals with conceptually maintaining identity when confronted by different philosophic propositions, posthulence, and presuppositions about the world and its nature.


Introduction to 3d geometry, yes that name of the chapter is not 3d geometry it's actually introduction to 3d geometry for the simple reason that you are actually 3d geometry is going to come in class 12th okay three-dimensional geometry this is just an introduction there's just a know-how of you know what is a 3d space and what what do the coordinates in a 3d space mean okay what is the section formula what is the distance formula etc so this chapter is not very long so I'm sure I can complete this in half an hour or 40 minutes so this chapter has primarily got only two concepts into it one is the distance formula of course there is a basic know-how and after that the main concept is distance formula which is just a one or two minute you know discussion and then there is a section formula okay with a section formula so under section formula we are also going to touch upon the concept of centroid of a triangle okay so that is also sometimes asked the main part of 3d geometry lies in class 12th where you will be studying about the concept of direction cosines ratios equations of lines equations of planes and various interaction of lines and things and let me tell you that 3d geometry will be along with vectors okay so there will be a touch of vectors in 3d geometry in class 12 right now it is just not even 5% of what you're supposed to know actually so before I start anything please recall what we had done in our 2d geometry in 2d geometry we basically had two reference lines which we used to call it as the x and the y axis correct and any coordinate had got a and b as the coordinates or any point would get would have to a two parameters a and b where a is called the abscissa b is called the ordinate the mod of the abscissa actually represents how far is the point from the y axis okay and mod of basically and we are directed distances to be you know short and simple okay so in case of 3d geometry we would require we would require three axes right so these three axes are basically oriented in a special manner which we call as the right-handed coordinate system yes so right now on your screen I have drawn a perspective view of x y and z now this angle is 90 okay this angle is 90 and this angle is 90 I hope you can see from the figure let me draw it like this okay but these 90 degree position of these three lines are not arbitrary they're not like chalo man kar tha to koi bhi three perpendicular lines you know you can draw no not like that it's not based on your whims and fancies okay these three coordinate axes are basically oriented in such a way that they form a right-handed coordinate system a right-handed coordinate system what is a right-handed coordinate system right-handed coordinate system is basically a system where if you let's say stretch your right hand in such a way that the edge of your hand is kept on the x-axis okay so I hope you can see the camera so basically the edge of the hand should be kept on the on the x-axis and then curl your finger curl your finger naturally towards your y-axis so curl this finger naturally or curl these four fingers naturally towards your y-axis in that case your thumb direction will be along the positive z-axis so what you see over here is a positive x positive y and positive z okay so we cannot draw our x y z-axis in any random fashion that we want to now there may be cases where the question setter will say you are following a left-handed coordinate system so the question will start with the disclaimer that assume that you are following a left-handed coordinate system in that case basically it is going to be the other way around that means if you curl your finger naturally or you can say you can take your left hand left hand and then curl your finger towards the y-axis then your thumb direction will be towards the z okay that will become a left-handed coordinate system but if nothing is mentioned you will follow a right-handed coordinate system please be aware of that okay now these right-handed coordinate system it divides our 3d space it divides our 3d space into octants now in in front of you I have basically shown a figure okay so imagine imagine as if you have a cubicle kind of a structure like this I hope you have seen cubicles in offices right I'm sure if you have visited an office in your school also you would see cubicles like this where people are sitting so here this is your x-axis this is your x-axis this is your y-axis direction this is your z-axis direction now this entire 3d coordinate system divides the space into eight zones which we call as octants which we call as octants it's just a second lot of noise coming from outside yeah so now octants just like we have coordinates in 2d system we have octants in 3d system now what are the name of the octants all of you please note down this is called the first octants as you can see this cubicle I'm trying to shade it this cubicle is your first octant okay in first octant everything is positive as you can see the sign over here x is positive y is positive now before I go to the signs let me just let's say this is our right handed coordinate system if you have any point in space let's say I call it as a comma b comma c okay in 3d coordinate system you need three coordinates a b and c a basically represents a basically represents the directed distance distance from yz plane I hope you can see this plane this plane is your yz plane I hope you are able to imagine it okay so a represents the directed distance from the yz plane now what is this direction if this is in along the positive x-axis it's a positive value if it is toward the negative x value it is a negative value so from the yz plane a represents the directed distance similarly b represents the directed distance from xz plane so xz plane is the one which is in front right now the screen of your laptop or your desktop whichever you are using that is showing your xz plane okay and c represents the directed distance from from xy plane xy plane is the bottom plane okay so c represents the directed distance from the xy plane so here in 3d geometry you have x so you have a b and c as three coordinates and if you are lying in the first octant then all of these will be positive okay all of them will be positive as I have shown it over here in the diagram also okay this is called the second octant in second octant x is negative y and z both are positive okay this is your third octant in third octant only z is positive both x and y become negative okay this is your fourth octant fourth octant x is positive y is negative z is positive the octant which is right under the first one is the fifth octant the octant which is right under the second one is the sixth octant the octant which is right under the third is the seventh octant by the way six I will not be able to show because it is hidden from the view okay and this octant which is below your fourth one is your eighth octant I hope you can note down the octant's position so in the exam they may ask you what is the sign of x y z in let's say third octant in third octant x and y both are positive negative only z is positive what is the sign of x y z in the seventh octant seventh octant everything is negative okay so such kind of questions can be asked to you so I hope there is no issue regarding the positioning of these octants and the sign of your ABC in these octants any questions okay now the next concept that we are going to talk about as I told you I will directly come to the point distance formula this is the very first concept that we normally study when we are talking about coordinate system so in 2d also I'm sure in 9th or 10th you would have studied about distance formula as the first thing so if I ask you what is the distance between two points x 1 y 1 z 1 and x 2 y 2 z 2 now it's a big challenge for teachers to actually represent a 3d point on a 2d space so normally what do I do I hate representing a point like this in 2d space so what I do I normally fix my coordinate axes like this I hope you are you'll be able to understand so this is your x this is your y this is your z by the way please imagine this is a perspective view that means this is right angle this is right angle and this is right angle okay this is a perspective view okay then what do I do let's say I have a point okay then I make a I make a you know cubicle box like this so that you understand that I'm referring to a 3d space okay yeah let's say I make a structure like this okay so let's say this is your point x 1 y 1 z 1 now I have oriented this cube in such a way that this is parallel to the z axis this is parallel to the x axis and this is parallel to the this is parallel to the y axis okay so I have oriented this box in such a way that this box side is parallel to x this box side is parallel to z and this box side is parallel to y okay and let's say this is point a and this is point b so let me call this point as x 2 y 2 z 2 now I want to find out a b distance now all of you try to imagine this in the room that you are sitting in all of you you're sitting in a room I'm sure nobody's sitting in a lawn or something I cannot deny it by the way some of you maybe so imagine that on the floors one of the corners of the floor is your x 1 y 1 z 1 point okay and the opposite diagonal in the ceiling is b point x 2 y 2 z 2 and you want to find out what is this distance you want to find out this distance a b okay now how will you find it out very simple first of all what is the coordinate of this point c I'm sure everybody will agree that c will have the same x and the y coordinate as b but same z coordinate as a because it is on the same floor see on the floor of your room all the points will have the same z coordinate isn't it unless until your floor itself is you know inclined okay so imagine that your room is says that the edges of your walls are behaving as your x y and z axis of course forming a right-handed coordinate system okay so this point c will have the same x and the y coordinate as this but same z coordinate as this okay so obviously this distance bc if I'm not mistaken will be z 2 minus z 1 to be more safe put a mod so that you know you assure that it is a positive distance okay what about this distance ac so when you talk about ac it is basically as if you have two points which have the same z coordinate they are only different differing x and y coordinates so this point is this line will have a length of x 1 minus x 2 whole square y 1 minus y 2 whole square you will be basically using a 2d formula over here because this length is nothing but as if you are trying to connect x 1 y 1 with x 2 y 2 because z is not varying at all okay now look at the triangle a b c this is a right angle triangle okay this is a right angle triangle a right angle at c okay so this angle here I hope you're able to understand this angle is right angle right so in a right angle triangle we can apply our Pythagoras theorem that is you can say ab square is ac square plus bc square ab square is let's say not known to us ac square the square of this will be nothing but x 1 minus x 2 whole square y 1 minus y 2 whole square bc square square of this you can actually write it as z 2 minus z 1 whole square or z 1 minus z 2 whole square doesn't make much of a difference and there you go this is your formula for the distance between two points in 3d geometry now this is very easy to remember because it is just an extension of the same formula that you have learnt in 2d is just that one more dimension is added to this one more dimension is added to this is this fine any questions okay we'll just take a very simple question on this not a big question question is find the locus of a point the sum of distances from 1 0 0 and minus 1 0 0 is equal to 10 so find the locus so here also locus questions are not leaving you so find the locus of a point the sum of distances from 1 0 0 and minus 1 0 0 is 10 okay so assume that the point is x y z okay what are the distance of x y z from this point let's say I call this as p and I call this as a and I call this as b so as per the question p a plus p b is equal to 10 correct so what is p a p a is under root of x minus 1 the whole square y square z square p b is under root of x plus 1 the whole square y square per z square equal to 10 now should you leave the answer at this stage it would not be a good idea to leave it at this stage so what I'm going to do is I'm going to send this term to the other side and I'm going to square both the sides by the way I'm not writing everything I hope you'll be able to understand what do I mean to say so you all know that when I take it to the other side it will become something like a minus b so a minus b square is a square b square minus 2 a b okay lot of terms will get cancelled in fact this 2 will get cancelled this 2 will get cancelled x square and 1 will also get cancelled so you'll have a 4x minus 100 is equal to minus 20 this okay drop of factor of 4 I believe I can you can always drop a factor of 4 okay square both the sides so this will give you x square minus 50x plus 625 on this side you will have correct me if I'm wrong 25x square 25 y square 25 z square minus 50x and I think plus 25 okay again I think one cancellation is going to happen that is this guy will go off okay now collect every term to the right side so you will have 24x square you will have 25 y square you will have 25 z square and take this 25 to the other side equal to 600 okay so this structure is that of an ellipsoid it's a 3d structure which you learn in your first year of undergrad that is called an ellipsoid okay any questions here any questions in the process I think the process was quite familiar to you you have already done locus questions in 2d okay I'll ask you a very simple question find the distance of find the distance of 3 comma 4 comma 5 from y axis find the distance of 3 comma 4 comma 5 from the y axis done see again make a diagram diagram very very important see when you're trying to reach when you're trying to reach 3 4 5 what does it mean you go 3 units along x you go 4 units along y and you go 5 units along z isn't it that's how you reach 3 4 5 correct now what I'm trying to ask I'm trying to ask how far is this point from the y axis that means if I drop a perpendicular like this okay I hope my perpendicular is appearing to be perpendicular so let me make up perpendicular like this yeah if I drop a perpendicular like this what will be the length of this perpendicular now it's very obvious that you had moved three units in this way and you had moved five units in this way and this forms a right angle triangle so this distance P will be following a Pythagoras with this so your P will be under root of 25 plus 9 which is 34 units okay so please be careful such questions can also be asked in your school exam so with this I'm moving on to the section formula so section formula is basically a formula which will help you to find out in what ratio or what is the coordinate of a point which divides the join of two points let's say there's a point a x1 y1 z1 and there's a point B x2 y2 z2 so if point C divides it in the ratio of m is to n what is the coordinate of C okay how will I figure this out now all of you please pay attention there is a small construction involved over here so I'll I'll make my coordinate axes first I'm not going to draw a big one because it's going to cut the line actually so this is your z axis this is your x axis and this is your y axis now imagine that this line is in space I hope my oh my camera is off so yeah see it's in the space like this okay now take the mirror image of this line on the x y plane that means drop drop a perpendicular from both in fact all of these points that you have a C and B okay so what I'm drawing here in front of you is a mirror image mirror image is basically nothing but as if you are taking the shadow so let's say there's a light bulb okay so what is the shadow that this line will cast on the ground so basically let's say this was your line I hope you can see my my camera this was the line I have a light source on top it will cast some riff you know shadow on the ground right so this is that shadow I hope you can you know understand that this is the shadow so this is right angle okay let's call it as a dash c dash and b dash okay now assume that c had coordinates x y z correct now you tell me what would be the coordinates of a dash c dash and b dash you'll say so simple a dash will be x 1 y 1 0 because you're taking it on the x y plane this will be x y 0 and this will be x 2 y 2 0 correct yes I know understood so far so far everything is good okay now what I will do this reflection as it is I'm going to lift it up okay so this reflection as it is I'm going to lift it up and it will basically appear okay let me just use my gadgets over here so I'm raising this reflection like this so as it is this reflection line I raised it up like this so that this c dash again matches with the c so see let's say this was your line okay I hope you can see it on this camera correct okay on this particular hand of mine whatever was the shadow let's say this was the shadow I took the shadow up parallel to itself so this line gray line and this pink line are parallel to themselves so I lifted the shadow out till what height I lifted it till your c dash and c again combines now tell me how much is the height by which I have lifted it you'll say sir z isn't it so if I have written it by z can we write the coordinates of the pink line as this a double dash will be x 1 y 1 z and b double dash will be x 2 y 2 z do you all agree with me regarding the coordinates of a double dash and b double dash any questions okay now do you all agree that triangle a c a double dash will be similar to triangle b c b double dash that means these two triangles which I'm shading over here they are are similar to each other correct so they're similar to each other can I say a a double dash by b b double dash is same as ac is to cb and ac is to cb even though m has come up let me write it again ac is to cb is m is to n okay so this is m is to n correct now a double dash is nothing but this height correct and that height is nothing but z minus z 1 because they only differ in the z coordinates x 1 y 1 is the same for both of them similarly b b double dash is z 1 sorry z 2 minus z am I right so this height is z 2 minus z so this should be same as ac is to cb ac is to cb is m is to n now this is a very wonderful relation that I have to get the coordinates of z 1 sorry z in terms of z 1 z 2 m and n so on cross multiplication this is what I see let's club up all the z terms together and let's club up all the other terms together so z becomes m z 2 plus n z 1 by m plus n now this is just one third of your effort we can say similarly similarly had you taken the projection of this line on the y z plane you could have got x coordinate as m x 2 n x 1 by m plus n by the same logic and y coordinate if you had taken its projection on x z plane it would have been m y 2 and y 1 by m plus n so there you go you have the section formula for finding out the coordinates of the point which is dividing a line in the ratio of m is to n which is given by this now you'll say sir this is again similar to what we had learned in our 2d of course it is we are not learning something very you know out of the box it's just that a third dimension is added to the point and everything that you have learned for 2d will also be applicable like if you had a case of external division we will change this plus to minus okay we'll change these pluses to minus if there's a case of external division that is known to you one very important point I would like to highlight when c divides it's join off a and b whether internally or externally a very important phenomena that must occur here is a b c must be collinear there is no concept of there is no concept of internal or external division if the points themselves are not you know collinear very good question product there is nothing called slope in a 3d line there is nothing called slope in a 3d line so how do we know the direction of a 3d line that is obtained from a parameter which we called as direction cosines which is a subject matter of 12th so we'll not be talking about it in class 11 there are three terms which we call as lmn okay so unlike in 2d where only theta was sufficient enough because if theta is given to you the automatic angle was 90 minus theta but in 3d we need three dimensions or three you know parameters or three you can say informations to know its direction which are called direction cosines about that we'll discuss in class 12s don't worry about it okay so there's nothing called slope in a 3d line slope of a 3d line basically becomes direction cosines so that is the right word that we use meanwhile I would like to take a question on this very very small question this question may come in your school exams also the vertices of a b and c are as given to you the internal bisector of angle bac meets bc in d find ad so I hope the question is clear so let's say you have a b and c question is if you bisect the angle a internally okay it will meet at a point d and they're asking you the length of ad okay forget about length of ad find the coordinates of d only okay let's say I change my question I make it more simpler find coordinates of d okay because once you know d ad is a simple effort you don't have to you know break your head for finding ad now all of you here must be wondering what is the ratio in which d is dividing b and c I have repeated this in properties of triangles chapter when we were finding the in-center and I'm repeating it yet again angle bisector theorem bd is to dc will be same as ab is to ac I hope everybody still remembers this angle bisector theorem it was a class 10th topic correct so for that I need ab length okay let's figure out ab length ab length will be four square five square three square which is actually root 15 and ac length is a one square one square four square which is actually root 18 which is three root two oh by the way five root 50 is five root two okay so even though the figure is slightly skewed I hope the idea is clear that ab is to ac will be five is to three so this is five this is three okay so once you know the ratio you can easily find out the coordinates so the coordinates of d will be five into four three into one by five plus three comma five into three three into minus one by five plus three and five into two three into three by five plus three okay so this will give you 23 by eight this will give you 12 by eight 12 by it is by the way three by two and this is going going to give you 19 by eight so this will be your coordinates of d clear any questions one such question you may expect to come in your school exams also okay guys let me tell you from 3d geometry of 11th no j e questions will come why because this is just an introduction this is not even like you know five percent of the chapter five percent if you come it's like one percent of the chapter okay so j e may not expect questions to come from 11th grade 3d geometry right even in probability also don't expect lot of questions of 11th grade probability to come in j e may of course questions will come which will be you know taking your class 11th knowledge but per se don't expect that you know they will ask you questions on what are types of events and all in in j e may exam okay j e may has got a lot of serious affairs to manage they will not ask you those simple simple concepts the last topic that i would like to consider over here is the centroid of a triangle centroid of a triangle uh why i'm taking this is because many times in school they may ask you questions so what is the centroid centroid is basically the meeting point of the medians right which you all know know they are concurrent at a point which is called the centroid centroid divides the median in the ratio two is two one two is towards the vertex side two is towards the vertex side okay so what is the centroid of a triangle which is having the vertices as these points so again the section formula is going to help us uh let's say i call this point as m m will be the midpoint of b and c okay so g divides a m in the ratio of two is two one so g coordinate will be two into this which is x two plus x three one into x one so i will let it over here by two plus one two plus one is three similarly y coordinate also will be y one plus y two plus y three by three z one plus z two plus z three by three okay so this is the coordinates of the centroid again no difference from whatever we have learned in 2d is just that an extra dimension has come into picture now one thing that i would like everybody to know here i think you must be knowing also if you make a triangle by connecting the midpoints of the sides a b b c c a let's say m and p please note that g will also be the centroid of triangle m and p okay so not only a b c that will also be the centroid of the triangle m and p okay so this kind of concepts are normally asked so they will say okay uh the midpoints are known find out the centroid of the triangle so many people what they do they waste time finding a b c coordinates okay so they find a b c coordinates they spend around four to five minutes there and then they use this formula to get the centroid or you can directly get the centroid by finding the centroid of m and p also that will give you the very same result you don't have to find a b c for that okay so these type of questions are also expected to come in your school exam so this is all we have for introduction of 3d geometry there is nothing much in it okay i'll be sending you some worksheets some handouts on this also try to solve as many questions as possible okay so next class


Hey, this is Brett, and this 2023 GMC Yukon XL AT4 Premium Plus Package is stock number 14263Z. I am here at Summit Automotive in Fond du Lac, Wisconsin, you're new and used SUV headquarters. This 2023 GMC Yukon XL AT4 has the 5.3 liter V8 gas engine. It's paired up with the 10-speed automatic transmission, and this vehicle has been fully safety and inspected by our service shop per the state of Wisconsin inspection process. It has a fresh oil and filter change, all the fluids have been checked and topped off, and it is 100% ready to go. This one also has the max towing package on it. I'm going to go all the way around in this video inside underneath, start it up, take a look under the hood, and give you the most accurate representation that I can, show you all the options. And this one is Redwood Metallic, really a cool color. Should all my videos in 4K, if you like the video, subscribe to the YouTube channel, click the bell notifications, get updates on the videos I do each and every day, as well as having access to one of the largest catalogs of vehicle walk-arounds on YouTube, and stay current on our ever-changing inventory here at Summit. Auto, this one comes with the factory 20-inch painted and polished aluminum wheels. They look really good. It has Goodyear Wrangler Territory AT tires. These are 27560R20s. They have, I would say, probably 70-80% of the tread left on them. Frame and underbody looks really good. This is a one-owner clean title history, clean car facts out of Michigan. You can see these are the auto-leveling suspension airbags on there. It has the LED headlamps, running lights, and fog lights. I will turn those on at the end of the video, so stick around for that, so you can see just how bright they are. You get the front bumper parking sensors. You get this dark, silverish gray trim on the grille there that looks really good. I think that's part of the AT4 package, GMC lettering, and the hood is in fantastic shape. I didn't see any dents or dings on there. Passenger side front fender looks really good as well. And the passenger side front wheel, no major scuffs or scrapes on there. Check out this redwood metallic. It's got a lot of metal flake in it, some yellows, some greens even. Really a cool color, especially in the sunlight. This thing really pops. As you go down this side of this 2000 and 23 GMC Yukon XL, take note of how clean the body is, how reflective, and mirror-like that paint is. Take these HD videos, so if you're far away, or even if you're close by, just cannot make the trip down, but you're still interested in purchasing the vehicle. You can see the vehicle, hear the vehicle, and have confidence in what you're looking at before you even get here. So when you do get here, there's absolutely no surprises, and you can make a smart and informed buying decision from wherever you're at. If this video helps you make that buying decision, let your salesman know that you saw the video, it was helpful. That brat sent you. Back wheel is in excellent shape, and the back tires have just as much tread as those front tires. You get the felt wheel well liner, which keeps your frame and underbody looking good. You can see any corrosion on that. Looks really good. It has the power running boards. I always like showing both sides, so you know that both sides are working properly. Coming around the back here, rear quarter is absolutely perfect, no dents or dings in there. Coming around the back, rear bumper has the backup parking sensors. The full towing package, of course, with the max towing package gives you the receiver H4 pin and 7 pin wiring. You also get the spare tire back there. Rear bumper is in really nice shape. The rear gate is in excellent condition as well, and it is a power lift gate. There is the receiver hitch cover. We keep those inside so they don't go missing, and these third row seats, they go down with power. There's also a little storage area. You get a weather tech floor map back here as well, and you can see it had stickies on the backrest, but those are not sticking anymore. So you get those seats down, you just press the buttons, see how fast they go down. Watch how it's crazy. I'm always amazed at how fast they go up as well, and they work nicely. To get this gate down, there's a button right here, press that. It takes a second, and then it comes down. And as we go down the driver's side, just as clean as that passenger's side, no major dents or dings on the rear quarter or door, and for full disclosure, this back wheel is just as nice as the rest. You do get the capitalist fuel fill, which is a really nice feature. Never get gas on your hands again. And down the rest of this side of this Yukon XL, doors look fantastic. AT4 lettering looks good, blind spot monitoring. These mirrors are heated. Built-in directional signals, the 360 cam there. Take a quick look at the second row, there are those power running boards on the driver's side. They're working nicely as well. Love the interiors on these AT4s. You get the black and orange or tan, whatever you want to call it, that color. Get the piping on there, the inserts on the seats. All weather floor mats back here as well. These back seats are heated. You get two USB C's, 120 volt, 150 watt plug-in, and rear air controls. These seats go down like so, and then you grab the strap and they release to get to the third row seats. Those third row seats are in fantastic condition as well. No rips or tears back there. They look really good. Smells very clean inside this vehicle. I don't think it's ever been smoked in, and then you can adjust these with that strap right there, or that lever. Child safety locks on the back doors inside and bottoms of the doors all look fantastic. I'll show you the VIN sticker here. No previously owned in Canada vehicles here. There is a tire and loading information sticker, and then GM is nice enough to give you the trailering information sticker. So it says a conventional towing is 8,000 pounds on this one.  No rips or tears on them. They look really good. You get the AT4 stitched into the headrest on the front seats. Side curtain airbags on there as well. Lumbar has weather tech floor mats in front. Auto headlamps, push button, four-wheel drive, factory brake controller, heads-up display. You get the power telescopic and tilt steering wheel. Stability control, downhill assist control, 360 camera, lane departure warning parking sensors, and your start-stop capabilities. Power windows locks, mirrors, memory driver seat, and these mirrors do power fold in. I was like showing both sides so that you know that both sides are working properly. You also get this really cool trim on the door. See if that'll zoom in there. Looks really cool. We'll hop inside, check out the miles, the radio, and everything that this one has to offer on the interior. Check out that animation at the beginning. Must be Mount Everest there. Oh no, that's Denali. Mount Denali. This is not Denali. This is an AT4. Anyways, you get that cool display there. You can see this one has 13,767 miles on that nice digital instrument cluster. You get a compass display, digital speedometer, tack on there as well, range to empty, and that's in really nice clean condition. You get the heated leather wrap steering wheel, Bluetooth and information center controls on the right, cruise controls, adaptive cruise controls, and heated steering wheel controls on the left, audio controls on the back of the steering wheel. Here is your touchscreen radio. I think this is a 10.1 or 12.3 touchscreen infotainment system. It does have the Google Maps on it. There's Highway 41, so that is working nicely. Now I don't know if you need a subscription for that or not, so just for a morning there. Anyways, you get your different AM, FM, Sirius, Bluetooth, Google News, Podcasts, Amazon, Alexa, USB. Hook it up any way you want. You get all your different apps on here as well, including Apple CarPlay, Google Assistant, the Play Store. You can check out your cameras on here. You might have to start the vehicle for those to work, so I'll do that in just a second. And then Trailerine, Climate, all that good stuff. Just a ton of stuff you could do with that radio. Down here are your more tactile, volume-tuning, climate controls, including your heated and cooled seat buttons, USB, USB-C, wireless cell phone charge pad, and a 12-volt power point. Here's your shifter for that 10-speed automatic transmission. Here is your keyless entry with remote start and power liftgate buttons on there. Passengers side format and seat are in excellent condition. No rips or tears on there. Smells very clean inside this vehicle. It's never been smoked in. You get the second-row fixed glass and power sunroof in the front, panoramic roof. You get the homelink buttons for your garage door security systems and lane systems, map lights, power fold-on seat controls, rear gate controls, sunshade controls, and on-star and SOS buttons. All right, let's start it up. Take a look under the hood. Check out all those backup cameras too. Anyways, you can see it starts right up. No check engine lights or anything like that. There are your cameras. You get the 360 cam right there, your front view cam down the sides of the front view so you don't hit any curbs. Then you can resume in on that receiver hitch to get hooked up to your bulk camper trailer the first time, every time. You get the front view camera and the 360 cam there as well. So a lot of really cool things you can do with this radio. All right, let's go take a look under the hood. Also has the Bose sound system. Might have forgot to say that, but you would expect an AT4 to have the premium sound system on it. I would personally like to thank you for checking out the video today and hopefully from this HD video you've been able to verify the quality condition options and of course, cleanliness of this vehicle all the way around inside. Now you can see all those LED lights are very bright and working nicely. Under the hood we have the 5.3 liter V8 gas engine. Engine bay is very clean, runs very smooth. Once again, this vehicle has been fully safetyed and inspected by our service shop because a fresh oil and filter change. All the fluids have been checked and topped off. Shocks are doing a nice job holding that hood up and this vehicle is 100% ready to go. There is the emission sticker and I would highly recommend this vehicle from a quality and condition standpoint.

Hello, and welcome back to theCUBE's coverage of AWS re-invent 2021. We're here in the studios in Palo Alto, California, two great guests, Linda Tong, general manager of Cisco AppDynamics and Gary Glenn, architect of operations at match.com. Thanks for joining us. We're talking about AppDynamics, match.com and customer experience, mainly around cloud migrations to Linda. Great to see you and Gary, thanks for coming on theCUBE. Great to see you again. Thank you for having us.  We've talked about cloud migration, application performance, modern application development, all powered by the cloud, right? So, this is really key and people are relying on the cloud and cloud scale and data to drive the digital transformation, the digital services and applications right now. How has the pandemic affected your customers and their expectations for digital experiences? Oh boy, I mean, the pandemic has been, it's been rough for our customers. You know, and part of that is what Gary's going to tell you a little bit more about today, but folks are seeing this increase in expectants of accelerated speed and delivering innovation, building great applications and iterating on them quickly and frankly, their customers demands for engaging with them through digital services. And that has led to this massive increase in, one, the types of technologies that they're consuming to build and deliver these applications and two, the complexity upon how they actually wrap their arms around it and understand what's going on and deliver these great experiences. And so it's been a rough road for our customers and what we find with AppDynamics in Cisco is our ability to partner with our customers to help them wrap their arms around that complexity. Gary, I'd love to get your commentary on this because I'll say match.com has been at large scale for many, many years and now the pandemic comes in, now a new user experience, more accelerated, more action, more things are happening, right? So this is truly the hybrid world coming together. I mean, it is kind of the same game but kind of new patterns are emerging. What have you seen in the pandemic around expectations and the services that you guys are providing in the digital experiences? Yeah, sure. So as you mentioned, match has been around for quite some time. We've been here for over 25 years. We have an interesting mix, heterogeneous technology, some old stuff, some new stuff, a lot of the mentality that we try to bring is to innovate. The pandemic brought a lot of uncertainty. We weren't really sure how people were going to react. Was it going to be everybody kind of hunkers down? Dating definitely is something that requires human interaction at multiple levels. And it turned out that people were still very much interested in getting to a place where they can find human connections and match as a premium product trust to make that delightful. And so we had our hands full, especially at the beginning, things like by-check of video features, how does that work? What are the expectations? Is that going to creep people out? If we try to just offer that, are they going to use it? How are they going to date? How are they going to talk? How can we make sure that they're safe? All these kinds of things went into it. And so when we've been using app dynamics for years now, well, before the pandemic, and we use that in order to get a gauge not just on the type of traffic and load, but also, hey, we've got these new features. How do they fit into this huge complex environment? And so some of those timelines that maybe were a little bit more relaxed were very much accelerated. And like a lot of companies, we had to figure out how to deliver on that. So, Linda, I want to get your thoughts. We've talked about in the past, app dynamics has been a leader in really accelerating value for customers. Now with the pandemic, you mentioned, these new experiences are being pulled in from the physical world, right? So you have things that were happening on digital in the application space. Now you have more experiences coming in because there's no places to meet face to face. Now it's coming together, but people have been seeing the value. Wow, I can, if I can't meet in person, match.com, I'm going to do some things, new things online, chat, whatever. This dynamic of old way, new ways changing and cloud is powering that. What are you seeing in terms of your customers journeys around what was once pre-pandemic and now post-pandemic? Well, big part of that is more and more of these experiences rely on digital services and these amazing sort of ways to connect with each other in a very digital space, expectations of customers have changed. So not only do you experience applications and you want it to be simple, easy to use, delightful and it delivers on the needs that you want, but on top of that, you expect it to be performant, you expect it to be secured, you expect there to be frankly no hiccups whatsoever because now this is your way to connect with others. This is your way to find dates or go on dates and the last thing you want is watching your screen pixelate as you're trying to have an important conversation and these kinds of experiences and these challenges as people build more and more of these digital services to build these connections, frankly require a lot more of folks like Eric and his team. They now have to deliver amazing experiences with perfect performance, no security risks, no bumps in the night and that's really tough, right? Expectations have gone through the roof. Yeah, the whole story on that one point just to kind of add live in this is that that whole concept of moving fast used to take months, right? I mean, weeks, months, now it's days and hours. So months to weeks, days and hours. Gary, this is the challenge, this is the opportunity with the cloud. Can you just take us through your cloud journey and your goals and some of the impacts that has had on your transition to the cloud? What does that look like? Yeah, so we've had our own firm data centers quite some time and we started putting our toe in, I guess, although it was kind of intense at the beginning, just trying to get people on board and just say, hey, this is possible. We started out with a fairly small SWAP team then managed within a couple of months working closely with our developers. We have a lot of smart people in background for all of our security folks, all of our devs to just demonstrate that we could do it. So we managed to take something like 80% of our front end traffic for most of a day just kind of spinning that up, learning lessons from that, knowing what we didn't know. Economics, if we didn't have that, would have been almost impossible to get a read. If for no other reason than just one little tidbit, we used to have a data center in Virginia and so physics being what it is, there's just been applied that we had to contend with. And for a couple of years, we hadn't had the 30 millisecond or so round trip latency on there. So all of a sudden we're going back to the cloud that reintroduced this latency. So what does that mean? Does that, well, he asked to sort of glide by and absorb it? How do we track it? How can we figure out what the delta is between, here's how we've done things on crime. Here's how it looks out here. Here are the cross calls. And, you know, App Analytics was what we used to be able to get a read and say, hey, look, it isn't as good as we know we can make it, but it's something in the starting point. Here's why we can show you the graphs, we can show you the data, let's do this thing. So we then pulled back and we have focused this year on actually our affinity apps, which is a collection of applications that are also being worried to be okay, Chispa. And so we've managed to get those completely migrated over. We're going to be running in hybrid notes for a while. We're going to need to be able to compare apples to apples, apples to orangutans, all that. And this is one of the main things for you to use for that. If I can just follow up on that just real quick, because I think this is a good point. You got the data point, you double down on that. You're looking at real data and then you look at success and you double down. That's the playbook. So, and the other thing is that you guys actually have a real operation that's running full throttle, right? So I can see that nice balance. What does the future look like beyond that? Because you got a business that's scaling, it's like changing the airplane engine out at 30,000 feet. You got to continue to push the envelope. Yep, so, and no, exactly right. Again, we're a premium product and so we got to back that up. And that means maintaining high availability. And so over the next few years, we're going to be looking at what can, what have we already moved? What can we move in piecemeal kind of way where it makes sense? What are the things that we can rethink? We're also using our dynamics as part of our containerization initiative. We've got lots of new virtual infrastructure, but was it, again, what does it look like on-prem in a container, go down the list of different things that might be different and then to be able to compare that to what it looks like running in the clouds. So it's going to be a while yet, but like a lot of companies, we got into this, we didn't think it was going to be done in six months. Even if we have to deliver those features at a much faster rate, the long haul, we got to make smart decisions and plan for capacity and get there. That's a real pragmatic approach. Linda, you and I both are sports fans. We've talked in the past about sports and the old adage, what inning are we in and growth? It's to use that baseball metaphor. I would say it's a double header. Game one, one by the cloud. Game two is happening now. The trend is this end-to-end mature, operationally focused customer base in IT where IT has shifted to the cloud right now and they're having this new view of what modern is. End-to-end understanding different stacks relative to applications. It's not as simple as it was before, but it's relevant. Can you share your views on how that's playing out because or do you agree with that and do you see that as an important part of the customer? Yeah, I mean, I think it's that complexity that IT organizations are seeing now as they fully adopt the cloud for all their new applications and start to migrate some of their existing applications over. That world is only increasing in complexity. The way that you can virtualize your applications, break them out into millions of services, the dependencies you have on third-party applications or SaaS services, these things only add that many more data points that you now have to cover and think about and make sure that those things deliver upon their SLAs. And wrapping your arms around that requires a partner to help you separate signal from noise because now you're going into a world without simplicity that you just mentioned has gotten to some point where it's beyond what you can actually sort of keep in your mind, beyond what you can just look at data and sift through and understand. You really need tools and systems that come together and understand that data for you and start to represent your business to you in a new way and abstract away those layers of complexity. While you do that, because I think as you talk about those innings, that first inning and second inning or rather first game, second game in the series, it's not a full migration to the cloud, right? There are going to be some applications that stay on-prem, that stay in their traditional environments and may never move. And then some of them are going to go hybrid. Some will keep parts of the applications on-prem and they're going to start to modularize components of it. And so it's not going to be sort of a mass-scale migration and then we're all in the promised land and we deal with the cloud complexity. It's going to be ever-increasing complexity as we now introduce so many variants of applications, so many variants of technology. And what people are going to need is someone who can help them cover that entire estate and understand it at scale. Yeah, I mean, I think it's the enterprise conversion, if you will, of cloud operations on-premises, because of the reason. And now you got the edge. Gary, this is the whole end-to-end stack conversation of you. And by the way, there isn't one tech stack to rule them all because you have different use cases. You might have an application that needs a financial gateway or have other capabilities. So integration's huge. This only increases the point Luna was making about complexity behind the scenes. How does AppDynamics help you with this for men? So we have an equitability infrastructure. A lot of it is shared. We also maintain sandboxes for user data and that sort of thing. And so navigating that space is always interesting. So for instance, one of the few things that we have coming out is a stir.com. It's out there right now. It's a data sector scared towards single parents. It does share some of the infrastructure, but realizing what that means, how is that different, how are registration flows different, how are subscription flows different? Where are the things that Dev is actively trying to improve on every think? That's one of the things that we try to focus on, when we're trying to kind of pick out like, is this a good candidate to move over to the cloud sooner or later? Is this a good candidate for something that needs to maybe bake a little bit more? And having established those baselines with the shared infrastructure and having a pretty good understanding of how they react, how they work, really helps us, you know, tee up these new initiatives and try to meet those needs in a more efficient way. So yeah, absolutely. What was some of the activity you guys seen? What's the peak activity on match.com these days? Yeah, so dating up in general, but on match in particular, we use a nested or pressed fractal peak. And it's a pattern that from what they told me back in the old days, took a little while to realize was a thing and not just like, oh, we changed something and then this produced that. So every evening is our peak basically. So we're taking time zones into account, at least in the United States, from about five to 10 o'clock at night or so, we get this growing burst of traffic so that can be anywhere from 23%. Sometimes it kind of varies. Then we have a weekly peak, where every Sunday and Monday, we expect a higher amount of traffic than we would other days. And it kind of makes sense from an archer psychology standpoint where you're coming off of dates, you're trying to set dates up. That's where a lot of that activity is. And then we have a yearly peak, which goes from around Christmas to President's Day. Believe it or not, it's President's Day, it's not Valentine's Day. And so that's the sort of thing where when we're trying to plan for capacity and we do a lot of what we call squeeze tests where not quite chaos engineering, but hey, what does it look like if we go down in capacity by 50%? What happens, where are the weak points? A January, Monday night is very different from a May, Thursday, and June. So we have to predict, we have to anticipate some of that, but we don't know for sure. We don't know, the lot can change in a year. So when we're preparing for our yearly peak, we really have to pay attention, we have to prep, we have to plan for that and work with that to figure out how we can get through it and maintain that level of service. That's awesome. AppTynamics has helped me to do that. I'd love to get a bot to give me the optimal dating times to share with my single friends. Great stuff. Linda, thank you for coming on. Great to see you. Congratulations on a great case study, great story. How large scale applications and are working in the modern cloud. So congratulations on your success. Thanks for coming on theCUBE, appreciate it. Awesome, thank you. So good to be here. Okay, CUBE coverage of Reinvent 2021. I'm John Furrier with theCUBE. Thanks for watching.
