are minorities being too harsh on white people in 2023 there's a new online movement that tends to think so so do they have a point or not oh man this is a complicated topic and it's probably going to be relevant in america for the next 20 30 years you know we're talking about the vibe between the tribes and uh there have been a lot of minority youtubers that are not white that have been getting like millions of views and having videos go hyper viral recently basically i wouldn't say fully a hundred percent but like sort of defending white people right yeah they're basically saying uh like hey guys we're we're always saying colonizer this white people evil this they're oppressor this we're oppressor that maybe it's just too much we're saying this too much and we need to back off white people don't deserve it and it's really not the situation that you think it is now whether or not you agree with this perspective we are going to go over all the different levels of things that we've heard about this topic and then we'll kind of try to wrap it up with some really big picture questions at the end if you guys are excited or interested by this conversation please hit that like button right now let's talk about what we're doing to white people the rising tide of racial hatred against white people in which there exists virtually no limit to what racial minorities can and do say about white people i believe this is the natural outgrowth of a perverse ideology that teaches us that everything every societal ill is the fault of white people and that whatever prejudice acts we may inflict upon them does not constitute discrimination because we don't have the power to discriminate yeah i mean andrew this video for example got one million views in one week basically asking minorities what are we doing to white people so we got to get into this because this is very very interesting in the comments section and of course we have some people going damn right it's open season on whiteness man i feel attacked every time i turn on the mainstream media man even the golden globes i hate it uh and then there's like rich elite white people who are like oh yeah you guys are a little bit jealous that we are the winners huh well you know this is capitalism and if you're not in first place that's too bad you know we won the hunger games and to the the spoils do the winners go or to the winners do the spoils go um andrew there's also moderate white people that i guess we're like you know gee golly i get that people are mad that certain groups are rich in america and certain groups are poor and certain groups are middle class but you know i just don't like how it's okay to like insult us maybe i want to help it but i just don't want to feel attacked all the time yeah and there's a lot of unprivileged white people who are like yeah you know man it seems like this open season on white people is like pretty unfair you know i'm just a farmer i'm a hard working white person i didn't get that much privilege growing up i'm just my lineage is irish we didn't have anything to do with slavery in fact the british were treating us like that too um of course andrew there was even like people who are asian latino black being like you know i'm a minority i'm not technically like a white oppressor but i feel like we're just the the rising tide against them is becoming unfair and just like we wouldn't like it how they treated us that way we can't reverse it like the bully can't all come together as a team and like bully the former bully right and then there's some perspectives that are trying to empathize with white people while acknowledging that something has to be done like the road to compensation for the past wrongs is not a pleasant one but it's a necessary one right i would say that that's a moderate left way of saying it right um some people are also saying you know white people are definitely not all evil but they are still the ones in charge of the power structure and they need to be constantly called out so that they can be changed from the top down for example if us minorities are at the bottom of the power structure how can the puppets hurt the puppet masters logically how can that happen right it's kind of saying like hey guys if we punch up at white people it's not really gonna hurt them because we're just trying to voice our opinion and try to get it out there now uh even on the farther left side a lot of people are like whoa white people viciously dominated and colonized the world for the past 400 years and now they want to lean into the victim card oh i am not falling for this trap white people think they're oppressed because of some tiktoks come on and uh there's one that's more structural i guess where they're like hey guys white people still make up most of the people in this country and they're definitely the people with the most money so we don't want to miss them piss them off guys it's like poking a bear and if we poke the big white polar bear it might just destabilize the boat that all the other bears are in the boat with the white polar bears why are we poking it and then the last two are hey guys you know we're all just some sack of bones and flesh and blood like all this tribalistic beef is stupid man we gotta just stop looking at color and just look at this like as a meritocracy we ought to just go back to what you can do right it don't matter who you are you're saying that's sort of like a bohemian or i guess like hippie way of maybe idealistically looking at it but yeah it would be nice to chill out guys and then of course there's people and always bringing it back to like class consciousness these people were like you know like international studies majors back in college being like you know that the only true warfare is class warfare basically the global elites want to cede disunity between the lower and middle classes about tribalism skin color and phenotype and let everybody fight it out and then they're not whole time they're not questioning this entire system of global capitalism that has all of them at the bottom and them at the top there's only elites and non elites none of this color stuff yeah and i would say guys at this point you've heard these are the major perspectives here leave in the comments down below which one of these you relate to most i know our channel we have a range of viewers because we don't really take one side very strongly so i think that there's going to be people on our channel who watch our channel that might relate to to all of these and you know what a harsh reality is in my opinion guys by the way you guys can leave your own opinion in the comment section below all of these and some more than others have some valid argument to throw into the pot however it would depend a lot on what family you were born into what socioeconomic class you were into and how much you take history into regards and how much and by the way everybody has a different timeline in their mind about how they view like modern day situations created by historical context right yeah well for example just whatever you were just talking about the end it's kind of like well if my parents went through it am i going to carry on that hatred or that pain or that trauma or that history right am i always going to take that into consideration every time i interact with a white person now if my great great grandparents went through it does that still count or if my ancestors from like a thousand years ago like i guess how far you're going to go back is a question that people personally need to ask because it's not wrong we do live in america this is a relatively new country i get it and everybody's just trying to make it and live a life however history matters right or maybe it doesn't i don't know but anyways guys here are three major questions that you want to be asking yourself when having this conversation because not everybody is having these questions even as they're leaving their opinion on all these videos andrew right i don't know if people have considered these questions yeah i i'm not gonna lie guys i don't love these tiktoks like i'm not saying that i don't understand their perspective and we're trying to you're talking about their anti-white tiktoks yeah i just like i don't think it's like great content i think they're just they're just almost like releasing something they're just like these are feelings and i want to put it out there in the world and there's a little clout to come along with it too you know not to say that that's not a factor but anyways guys let's talk about this because uh number one is it possible that it is more class warfare than race warfare i hear this argument and this is sort of sounds very smart right and it sounds like you read a lot more books than other people because obviously typically more blue collar working class people and the easiest thing to see is a visual phenotype right differences and cultural food and rituals and stuff like what's the flaw behind this well i think that there's something to it however the flaw is that in the way that america was constructed there is like almost like an unbreakable bond between class i mean socioeconomic status and race yeah yeah it seems like yeah because of the way america is such a newish country you know 300 400 years old and the history of slavery and the way that certain minorities were brought over to like uh not get fairly compensated obviously as slaves and other things in dental servitude so that's the only part where it's like yes i think in a theoretical sense class does matter more than race because say for example and a brawny james son of a billionaire lebron obviously we all know lebron he's growing up super privileged right right but then people are gonna say well is he gonna be privileged if he has a downside interaction with a police officer who doesn't know who he is or etc etc so it gets into these like hyper layered things so i think that that's where it's like yes there is something that class is more important than race but then also race is so interconnected with class now i think the linkage is debatable on whether it's one to one or what the percentage linkage between class and race it is right like i think a lot of people are going to debate well it's linked a little bit or it's linked a lot or it's linked like one to one right i don't think anybody would deny that there's a huge linkage between class and race right if you just look at the macro statistics on any sort of survey to play out that way are you saying i got to change my tune it's not race wars in america i got to say class wars in america and then what if you the second line was like but then racing class in america are instinctively linked according to statistics every single study it backs that up man all right point number two how should dominant groups historically and obviously you're gonna be looking at anglo-saxon people germanic people whether that's netherland british german whatever you know that zone how should dominant groups historically over the last couple hundred years treat groups that are been historically oppressed or poor yeah i mean that's a crazy way to put it right i mean that's what we're referring to as far as the american context goes i totally get it in other countries the the winner is is russian or chinese or you know whoever it is in any other country you know us man this is what i always talk about man i like proposals man i like proposals i like someone to come up with a plan and say hey guys listen white people you guys are still at the top yes maybe not all of you are born super privileged but anyways white people are at the top guys so can you just let us talk whatever crap we want to on tiktok and then you guys just this is this is the payment this is what we get to do and then eventually we'll just chill out and everything will be fine or we need x amount of money we need money we need the fifty thousand dollars or two hundred thousand dollars from you each you know it's tough because i think the people being emotional on tiktok whether they have a point or not obviously it's like it is insulting right i think that it's undermining the actual progress in two ways one it's undermining it because that person feels like they did something but they just had an emotional release even though it was driven by real trauma or what they feel like was trauma like they feel like they did something but there's been no structural change right and then number two i guess it makes people who are white or i guess white sympathetic sympathetic to that perspective like it hurts them so then it makes them not want to enact change when somebody does come through with a real proposal but david why should we care about what white people feel because they didn't care about what how we feel for decades kind of true yeah on a large scale i got that too man like i said man we used to be um dude we have been around so many people like when we were in business school in college uh you have to test in a business school and do all these get these referrals and stuff like that like that was definitely more right leaning if you made me draw you know a spectrum out it was like at least one notch to the right and me and you actually hosted a spoken word poetry show um there was almost like deaf poetry jam i'd say it was like two to three notches left leaning so we have been exposed to like both extreme ends of the spectrum as well as moderates on both ends of the spectrum i think there needs to do there needs to be some type of like force collaboration kind of like school projects you know how like you don't always get to pick your partners and then you got broken into groups and then you had to do something together and work together even if it was that class person in the class that you don't like but like we need to be able to do that on some adult level because it feels like sometimes everybody gets into their echo chambers and then the hate breeds and i don't think but here's my one thing the tiktok hate white people out there watching that's not like the worst hatred i'm not saying it's not my feelings hurt by what do you mean it's not the worst who are you to tell me it wasn't the worst i'm not saying it's not insulting i think it is insulting but i just don't think it's that bad it's not physical violence like literally like asians to this day we're getting like targeted by crazy deranged people of course but we are getting targeted in the streets you know for something that i don't know what it is i think it's a lot of white people who feel like the score was zeroed out and then they hear the insults on tiktok and they're like how come this isn't getting taken down but if i had done that about asians blacks or latinos it would get taken down that's structurally unfair and they have to understand that there's a historical context right but then it's tough to say right because if we got told that everything's supposed to be colorblind in public school then i could see where they're coming from that's why it's so complicated guys yeah i mean listen if it's hateful speech it should be hateful speech no matter the color of your skin all right guys uh the third point is who is even white oh my privilege david who do you count as well it's crazy who do you count as white but spent non his you know yours it's not because like uh let's say for example we're talking about the colonization of latin america andrew that was by dominant people from white looking people from spain right they don't look fully anglo but like like so the so let's say for example somebody is from mexico and they're white mexico which is generally like the richer ones right so they're the white people of where they come from but then they come to america do they automatically become a minority even though they're still just as white i guess theoretically european i think that's why they have that label non hispanic white you know that's not so complicated how come nobody ever talks about that like on all the surveys you have to mark are you hispanic or non hispanic white you know what it is i think in canada they do a lot more education about like are you anglo are you franco were you a germanic were you a scando were you mediterranean italian greek portuguese they i noticed in other countries they actually split up their whites but do you think andrew that we should be more like break that down in america because why do we just have like one word for actually the largest single demographic in america yeah because i i think it is so crazy you know it is true at one point in american history irish people and italian people were both considered like colored at a time right because they're catholic and they're they're technically non anglo right because some of the irish they're like healthy but of course now you would say almost italians and irish people they pretty much have blended in and they kind of get like the white card but would you i'll say they are not white anglo sacks and protestants from the elite plymouth rock you know we're talking about like land owning back to like the colonies days and manifest destiny pushing westward and then there's like light skin of people who are part white or part light skin something that like they look white but they're not white and they don't identify but then they're like 10 percent white but that could have been like a very dark history about how they became 10 percent white or are we just going to be talking about the waspy billionaire families like if we just want to point out the top hundred or like thousand families in america that are clearly white that may be benefited from the atlantic slave trade right but then hey benedict cumperbatch his family has some lineage of slave owners in the caribbean unfortunately but and i think edward norhan did that show and he was a descendant of pocahontas on one side and also a slave owner on another side and somebody i'm talking about another celebrity they found out they were like five percent african-american on one side but you couldn't see it visually right well i guess these are all just uh these are tough questions to ask but they are important questions to ask because like we said at the beginning of this video this is going to be a conversation for years to come like all these questions what about slovak whites andrew if luke wins mvp which i think he will andrew and then yokich might honestly throw out his career i think yokich is going to win at least three is that white privilege they're slovak yeah that's like a whole another thing they never even left that zone i don't know david all right let's wrap it up guys i want to see your comments down below you guys let us know what you think about this conversation or this movement that's helping kind of defend white people and say hey minorities back up guys it's getting a little too crazy or maybe it's not too crazy because i think there's another side that may be saying and that it just because people are yelling on tiktok it doesn't i don't know if that's something real real yet i don't know i just wish that there was more constructive conversations around the tribal the vibes between the tribes in america and i get it that you know we don't feel like a lot of minorities don't feel like maybe that anglo-saxon people or people who identify as that were the best winners like you know how there's a sore loser and then there's a sore winner i would just like i didn't want to be a sore loser i wouldn't want to be a sore winner even if we feel like we had that done on us but then at the same time who am i to tell anybody else especially somebody else who's like yo you guys are asian you guys didn't even see you guys saw like a quarter a tenth of it you know me compared to what we saw so yeah i don't know guys that's why it's complicated guys that's why the video's taking the white side if you're a minority it gives like a million views well that's why it's easier to just say hey stop everybody or hey open season on white people literally those are the two sides that are probably the most popular what we're trying to discuss right here it is the less sexy middle part of it all but anyways let us know in the comments down below hit that like button we are the hot pop boys hopefully you found this discussion helpful maybe mildly entertaining as well and i just hope this i hope that as we move for the next 10 20 30 years the vibe between tribes even if we can't come like to a serious like agreement agreement we could just like be chill we could be chill we could have the discussions in a you mean a more constructive way i'm not saying i think we should have the discussions though all right everybody let us know in the comments down below thank you so much for watching the hot pop boys and until next time we out peace


We have three charges kept like this. These are fixed charges. Let's say now imagine I Take this plus two coulomb charge and slowly move it along this path and Bring it to this point so that now it is at a distance of three Meters these are all in meters from the charges the question we want to try and answer in this video is in Moving this charge how much work did that external agent? That is me. How much work did Mahesh do in Moving the charge from here to here and we also want to calculate how much work did the electric field? Do when the charge went from here to here? How do we do that? Well, we can always go back to our basics and say hey work done is force into displacement And I can try and do that over here the problem is that the force keeps continuously changing Right as I come closer and closer to the charge the force might start increasing Which means I have to do some integral and look at that path taken off. No, we're not going to do any integrals over here So to avoid integrals we introduced the concept of potential energy But whenever I used to do these calculations I used to always get confused with the science Is it final potential energy minus initial or is it initial minus final potential energy and I used to always be confused So here's what I like to do now. I always always like to go back to gravity because that helps me It's a very simple case. So let's go back to gravity and think a little bit about it So imagine I have a stone lying on the ground What happens when I again Mahesh I move it up What happens? Well, let's say I did I Did hundred joules of work in pushing it up. I do positive work in pushing it up What happens to the potential energy? Well, if the initial potential energy was zero when I do work I add a potential energy into this rock and so the potential energy of the rock Increases by a hundred joules, right and therefore work done by me Mahesh work done by the external force that Equals the final potential energy Minus the initial potential energy of the system. So let me write that down. So the work that I do That equals the final potential energy minus the initial potential energy and What about the work done by the electric field? Well, I go back over here ask myself What is the work done by gravity over here? Well, when I'm pushing up when I'm putting a force on it upwards gravity is always putting a force on it downwards So gravity is putting a force in the opposite direction, which means gravity is doing negative work So the work done by gravity would be negative hundred Same will be the case over here the work done by the Electric field instead of gravitational field will be the negative of this. So that would be initial potential energy Minus the final potential energy. Does it make sense don't ever ever mug this up because we will forget that Always go back to gravity take a simple case and that will always help us in coming back over here So this means all I have to do now is think about what was the initial potential energy of the system? What is the final potential energy of the system and then we can figure out the work done? So encourage you to pause this video before we move forward and try it yourself All right, so let me let me draw what the initial put initial system looks like This is what initially it looked like 10 10 meters far away from each other Then when I once I did that work the final system looks like this And so the energy of this would be the final potential energy And if I subtract that I'll get the work done by me one thing you may be curious about is hey What about the path taken doesn't that matter? No, it doesn't because electric fields are what we call conservative fields It doesn't matter what path you take all that matters is the what is the initial state and the final state the work done is path Independent. All right, so let's go ahead and figure out these potential energies. Let's make some space over here All right a quick reminder of how we calculate potential energies of a system We've seen this in the previous video the way I like to remember is first think about what is the potential energy of Two charges the potential energy of a system of just two charges would be k You can call it one two k q1 q2 divided by r One two with r12 is a distance between these two And now if you want to calculate potential energy of system of three charges you take two at a time It will be the potential energy of this plus potential energy of this system plus potential energy of this system Same would be the case over here and once you substitute we can subtract and we can get an answer So again, if you haven't tried before maybe now would be a great time to pause and try All right, let's see. Let's start with the final potential energy Over here. So that's going to be k I'm going to keep the k as it is and I'm going to put a bracket because k will be common everywhere So first let's take these two charges. So q1 q2 is going to be minus five times minus five. That's 25 Divide by the distance between them. That's 10 plus Then let's take these two charges. It's going to be minus five times two q1 q2 minus five times two. That's minus 10 Divide by this distance. That's going to be three plus Let's take these two charges. We'll get the same answer as these two charges. So again, it'll be minus 10 over 3 And I'm not simplify Let me just go ahead and write what the initial potential energy was going to be sometimes things cancel out So that's going to be again k I'm going to take these two charges first. We'll get the same answer as what we got over here. So it's 25 by 10 plus When I did these two this time, I'll get minus 10 divide by 10 So minus 10 divide by 10 and I can I get the same over here minus 10 Divide by 10. I have to now subtract this. So when I subtract this cancels out and So finally, what do I get? Okay, you can do this yourself. This is just now subtraction Let me quickly do it. What I'll do is this will be minus 20 by 3 and this is minus 20 by 10 So I'll take that minus 20 out and what I have here is one over three And what I'll have over here is minus one over 10 because we're subtracting Minus one over 10 you can check you can pause and check so we'll get Minus 20 times k times. What is this 10 minus 3 7 7 by 30. So this cancels and that'll end up with minus 14 Over 3 and now I'll substitute for k. You might remember k is 9 times 10 to the power 9 So 3 cancels out Let me write down over here the final answer the change in potential energy is going to be minus 42 So let me write that somewhere over here. Okay minus 42 times 10 to the power 9 Joules that's the change oops that's the change in Potential energy Therefore the work done by me Would be just this number minus 42 Billion Joules 10 power 9 is I'm just saving space over 10 power 9 is billions I'll say minus 42 billion Joules and what is the work done by electric field It's going to be the opposite of that. So I have opposite sign. So it's gonna be plus 42 billion Joules and by the way, this this is only happening to be true because I'm slowly moving it without any acceleration Okay, I think I forgot to mention that in the question. I'm slowly moving it without any acceleration. That's important That's why the total work done would be zero because there is no acceleration. There is no change in kinetic energy Let's quickly try one more. We have three identical charges kept at the vertices of an equilateral triangle and let's say an external agent again me Let's say I come in and I move all the three charges now. I Move all the three charges in the given path and such that they form a new equilateral triangle of having edge length R And the question now is in doing so if if I move it very slowly without any acceleration What is the total work done by the electric field? So can you pause the video and give it a shot? All right, so just like what we saw earlier the work done by the electric field is the negative of the work done by me So it's gonna be negative of final minus initials gonna be initial minus final. So it's gonna be initial potential energy Minus final potential energy And the initial system is gonna look like and the initial potential energy will be the potential energy of this system The final potential energy will be the potential energy of this system. So I can just go ahead and calculate So initial potential energy is going to be just like before I can take two charges at a time K Q 1 Q 2 by R But notice this is since they're all equal. It's gonna be just three times this number. So it's gonna be Three times K Q 1 Q 2 by their distance So it's Q square by 2r plus Q square by 2r plus Q square by 2r that's gonna be three times I'm just trying to save some time and space over here and The final potential energy is gonna be very similar instead of 2r. It's gonna be R. It's gonna be 3k Q square Over R and now the work done by the electric field is going to be This minus this initial minus final you to be very careful about the signs over here So everything there are 3k Q square by R is common What remains now inside? Let me write that let's not do too many things in our head So 3k Q square by R is common when I subtract what remains is a half here minus what remains is the one here So that means I end up with Minus half so I get minus 3k Q square By 2r this is the work done by the electric field in moving in changing that configuration


Good morning everyone, I am Malpri Peri doing my pre-final year in engineering from India and as you mentioned I am doing a project for government of India these days which actually tells about which is totally dedicated to older people and the rest of background has been discussed. So first of all I would like to thank all of you for sitting over here early in the morning to have my session and then so yeah let's continue with the talk. So my talk would be on Twitter wall using low-click APIs. Low-click I have used to some of the APIs to build a local Twitter wall. So why have I gone to Twitter wall and all? I will be explaining in the talk. It is a very interesting story kind of thing. So yeah this is me by the way in the picture. I look a bit different but it's okay. So that is my Twitter handle you can find me over there and my GitHub profile has all the projects I have been doing and I am doing right now. Then what I will be covering in the talk is what is low-click? What is a Twitter wall? What are the steps to build a Twitter wall? And how will you run a Twitter wall in your local system? And trust me it's more easier than creating your Facebook account. I agree with you. So what is low-click do? What is low-click? So low-click is a server application which actually collects all your data related to various sources, various social applications but mostly on Twitter. So this has a search index and this search index is mostly based on Elasticsearch and it uses Kibana and then it has a peer-to-peer sharing interfaces also which helps you to talk to your peer who also uses the low-click and makes your work more easier. And then you have this totally in the back end which helps you to retrieve all the data related to Twitter so that you can do your analytics related to Twitter or any other diagnosis you want to work with the tweets. So what was the problem and what are Twitter walls? I will be explaining in this slide. But when you attend for a particular event and you want to find what is happening in that event, you actually have to go to those sources and got to know that what event for example take this conference. You don't know what is happening in the other hall when you are in need of this. But if you have a local Twitter wall for this event, you can just tweet it so that the other people in the other hall can also read that in the Twitter wall and can actually get to know what is happening on the other side of the world. So that was the reason I got to know, I was fascinated. Personally I went to a hackathon called Medfordale. It was conducted by the Government of India and Israel together. So in that we got to see some Twitter wall. That was hashtag Medfordale and everybody tweeting on that using that hashtag Medfordale was reflecting on the screen. So actually that fascinated me a lot and I thought okay this is something kind of information kind of thing because people who are on the other side would actually be knowing what are we doing on this side. So if they are interested after their work, they can just join us. So this was the idea that I had and I thought I should actually implement this but getting information from Twitter is kind of messy job because you have to run for this API acceptance and all this stuff. So I was actually searching for a project or a server technically so which would help me to get all this information so that I can put it on the same place for one hashtag whatever I have created and that I could reflect on a screen that would help not only me but also other people to actually join into it. So this was a basic idea that I had and I wanted to implement this. So that was the problem and then I got a solution of Twitter wall. So I actually didn't know what Twitter wall was. I just knew that there was a screen where I was getting all the tweets related to that event. So I went up to people and I asked what are those things how are you getting all the tweets related to a particular event. So that's when I got to know about a concept called Twitter wall.  That is what a basic Twitter wall is. It's as simple as that. Then when I went to the conferences and all I saw these kind of Twitter walls and I wanted to build one of my own kind. So why did I choose slow click? So I told you I was searching for a server which would help me to get all the tweets. So in that process when I was going through all the projects or organizations or whatever it was so barely because of someone's help I got to know about low click then I went through the documentation and this kind of fascinated me because you can just use its data being an anonymous person and you can actually play with the data which is a very bliss kind of thing for a person who wants to play with all his stuff. So why did I choose only low click? It collects large amounts of data from Twitter and you can just put it together then you don't have to undergo the authentication all the time for your APIs or requests and everything and you can share your tweets or tweet archives with the peer of low click. So I am using low click and any one of you are using low click then we can actually communicate through our tweets we can share our data, we can share our statistics and we can actually help each other in developing our own stats. And then... I'm so sorry for my throat first of all and you can use this data and create your own evaluations you can do anything you want with the data and the data is more secured over here that is the best part you have this fears of getting data from somewhere else and maybe your system may crash sometimes it happens that your system hands out so all these things I think this never happened to me at least during my project time. Next, what are the goals for this thing? I wanted to learn all or some APIs provided by low click and I also wanted to build a Twitter wall of mine my own very Twitter wall and so how did I build a Twitter wall using low click? In this what I did was February 22nd and 23rd we had a fest in our college which is our native fest so there I built this Twitter wall by that time I just posted it in my college and I used a hashtag I'm sorry I don't have those screenshots but it is called Mayhanvesh so I created a hashtag called hashtag Mayhanvesh2k17 and I just told my peers that whoever want to you know use this just use this because I want to know how it looks like so I just told them you do it so they started tweeting with the hashtag Mayhanvesh2k17 and trust me there were around people of my college and other colleges visiting so they we got some around for 2 days we got somewhere around 3000 tweets that was like wow because we had like 2 days we have more than 500, 600 attendees and everybody started tweeting like once I told them there is a Twitter wall you can tweet, you will be displayed in the things they started tweeting it because they wanted their profile picture to be there that's the definition so then they started tweeting it and the search API of lowcluck it gathers all the tweets that has this hashtag of the event you created and so it started displaying and actually it went very well my management was happy for that project so and then so how do you for designing this lowcluck wall you have only 2 steps involved first you have to have your setup I mean server in your system that you should have a great GUI so that your people are happy to see it so first one is installing your server so installing your server you just have to clone the repo this is the link of the repo and then you have to do the steps like CD, you have to shift to that lowcluck server directory then build a gradle before to this Apache ant happening but now I prefer going for gradle build because it is better tool than Apache ant then you have these steps to follow like you have to activate the server for the first time using a command of java the next one you will have to do some basic commands so for the first time when you do this command like java hyphen xmxig hyphen so after you do this you start doing the command CD build so that it makes your server run automatically and you don't need to setup it all the time so once you set this up with these two commands your server will run all the time so then the next part comes to your GUI so for this I have used flask as my framework and so server is set so that your twitter wall will be ready to work so you have to create a GUI which the way you want your twitter wall to look like then you have python to act like framework and this is the step by step I will show you in my demo how do I do this so once you complete these steps you can see your twitter wall on the cool so this is the address where you can see your twitter wall this hyphen 5000 a local host is the local host of your system it depends on the IPv4 address of your system next this is how my twitter wall look like this was the GUI and that was a tweet I did for false asia so and back said you can see some other tweets but I wanted my picture on the ppt so I took my next so I will show you the demo so if you can see I have already done all these steps but I will show you once again word from scratch so CD first you will go to the directory where your local wall is present is it ok this is fine ok so you go to the directory where your local wall is present then so what are the future plans of this project it is still in its initial stages and I want to make this a UI more better and probably will be using this for other other than my college one I told you so yeah any questions the initial installer for the server that includes elastic surge cabana all that sort of yes for local wall server are you asking ok I still didn't I am sorry I will be doing it by the way anymore so yeah I am developing a project for the government of India which actually tells that there is a scheme called Indira Gandhi Avaz Yojana so under that the old age people or the people who are eligible for that scheme should get pension for some amount so due to some reasons there is a database called NSAP database which has the all the information related to who has to get and how much has to get so due to some conflicts of database or because of some reasons there are some people who are not getting it who are eligible, who are not getting it so what we have to do is we have to segregate all those people area wise and put them on together and we have to swap it with this database also so that they start getting this pension install those tweets keep it as a data I didn't get you it should be stored and in this case it would be elastic search and index there yeah this is basically I have done this for Phosasia I have used the keyword Phosasia for this but actually if you want you can change this multiple you can do that but I have given the default keyword as Phosasia in the same tweet


Hello friends, I am Sanjay Gupta. In this video, I am going to demonstrate you how you can print transpose of a matrix by passing 2D array into function. Before starting, you can note my information, you can follow or subscribe my YouTube channel through the URL youtube.com slash sanjaygupta underscore tech school. You can download my programming app, Techimus, which is available on Google Play. Now I am going to implement the solution of this problem with the help of C programming. So first time including a header file that is stdio.h. Now I am declaring a function whose name is print. Its written type is void and it will receive a 2D array as an argument which is of integer type. So this statement is function declaration. Now I am defining main function where I am declaring a 2D array and then two variables i and j. Then with the help of printf, I am going to display the message enter elements on console. Now I am implementing nested loops. These nested loops will read elements from user with the help of scanf. J will be providing row index and J will be providing column indexes and the entered elements will be received through this scanf statement. So this is the reading process from line number 7 to 10. Now I can call print function which will be displaying matrix transpose. So this is function calling statement and after calling I am writing return 0. So I have implemented the complete definition of main function. After that I have to define print function. So print function is receiving an argument that is 2D array of integer type. So this block will be known as function definition. Inside this function definition, I am declaring two variables i and j. Now to print matrix transpose, I am again implementing nested loops. Where i is providing row index and j is providing column indexes. So inside j loop, I am using printf which will display element of a matrix. But here I am using indexes in reverse order like swapped. So normally whenever we print the matrix, we use aj. But here I am using aj because I want to print transpose of matrix. So first I want to approach column of the matrix. So for that purpose I am using aj. So if I write aj, then I am printing first column on the console. After completion of j loop, I can apply slash n. So this way I have implemented the definition of print function which is displaying transpose of the matrix. And instead of aj for printing, I am using aj. Now I am executing this code. Sorry, one more. Currently this is required. So here you can see I am entering the elements. Now you can see the result. I have entered 1, 2, 3, 4, 5, 6, 7, 8, 9 row wise, but it is printing column wise. So the transpose of entered values are printing in front of you, which is the correct notation. If you want to show the message printf slash n, transpose is... So with this message, output will be printed with a caption. Sorry, semicolon is required. So again I am entering the values of matrix. So you can see the result. 1, 2, 3, which is available in row. Now after transpose it is printing in column. Then 4, 5, 6 again converted into column and 7, 8, 9 is also converted into column. So this way I have printed transpose of the entered matrix with the help of function. So I hope you have understood how we can pass a function. Sorry, how we can pass a 2D array into function so that we can print transpose of the matrix.

A few months ago, I made a video talking about how I was going to start doing all of my work, all of my web browsing, basically everything inside of a virtual machine environment. And I had this whole grand plan where I was going to have a separate virtual machine for work, I was going to have a virtual machine for my web browsing, I was going to have a virtual machine for this and that and, you know, basically everything I was going to have virtual machines all over the place and I was going to switch around between them like I was playing musical chairs. I had this whole plan and the idea was fairly sound. Now, I made several different videos talking about that process and the experience over the course of the first month or so. And I did stick with that plan for several months. So I was creating virtual machines. I lived in them. I did most of my work in them. And I did a good job of transitioning a lot of the stuff that I usually do on bare metal over to those virtual machines. And I was very proud of myself because I stuck with it longer than many people thought that I would. And that was the primary comment on that initial video was that, yes, this is something that you can do, but it's often too much hassle and you're probably not going to stick with it for very long. Now, first of all, thanks for the faith, guys. I can stick with things when I want to. I can. No, I can. I definitely can. OK. So I did stick with it for a few months. So I proved those doubters wrong. But I will say this is that they were 100 percent right, that it is a lot of work and a lot of effort.  And also I made several mistakes along the way. And I'll talk about those today because my VM experiment is over. I'm no longer. It's not like I'm never going to make a VM again. That's not the case. But my experiment of doing all my work, all my browsing inside of the VM, it's just I'm done with it. So I want to talk about that today. But before I jump in, if you'd leave a thumbs up on this video, I'd really appreciate it. So why am I stopping this? Why is the experiment done? Well, there are many different reasons. First off, the process of actually doing this, of setting up VMs and making those VMs actually private is more than a one step thing. You can't just install Ubuntu inside of a VM and then be private. That's just not the way that it works. And I knew that going in, right? I knew that there were extra steps. But my philosophy was that I needed to take one step in order to actually get all the way through the journey, right? You know, one step starts the journey. And my initial step was to do the VM thing. And then I knew eventually I'd, you know, I'd install a VPN. I'd install a hardened browser. I'd do all the things that you need to do in order to maintain your privacy. And I did all those things and I didn't feel more private. So here's the thing. And it's probably a situation where a lot of us actually are, it's probably a situation where a lot of us are in the same boat, right? We do have to use Google from time to time. Now, I know this doesn't apply to everybody. A lot of people have successfully de-googled their lives.  I would, I just wish that I could, but I can't. Okay. And well, when I say that I can't, I mean, I literally can't for my work, I use Google Docs. I have to use Google Docs because that's what the company uses. Okay. I can't avoid it as much as I want to. Now, I do manage to only go there to upload things, but that doesn't really matter because it means I have to have a Google account in order to do it. Now, I was always going to have a Google account because I have a YouTube channel and YouTube is owned by Google, which is owned by Alphabet, which is probably owned by the CIA or something. I don't even know. The point is, is that Google owns my data already, and despite my efforts to prevent myself from being tracked online, I still felt not private, simply because I still had to exit out of my VMs and go to a place where I could actually sign in, which, you know, I had a VM just for places where I needed to sign in. I'd go over there, didn't do my uploading, and it was, it was a mess of actually having to SSH into the other machine, which was still running to get the data off of it because that's where, you know, I was private and doing work in that data or in that VM. And then, you know, it was, it was a mess. And at the end of the day, I didn't feel like it was worthwhile because I didn't feel more private. Now, if I could do Google my life, if I could completely shut my YouTube channel down, quit my job probably, you know, and just completely delete my YouTube or my Google accounts, all of them, I could probably then feel much more private and this whole VM thing would actually make sense because it would be, it would allow me to segment things and be connected to different VPN servers. So if I'm doing any searching or whatever, I can appear from sweet. And if I'm doing something on, you know, YouTube, I can appear from Chicago or whatever, you know, I can kind of play the whole whack-a-mole game and try to be as private as possible. But because I can't do that completely, there's that one gigantic leak. When it comes to my privacy, it just feels like it was not worthwhile. And when I added on top of the problems and the mistakes that I made, it really wasn't worth it. It was just really, really wasn't worth it. So let's talk about those problems and the mistakes that I made. So let's start with the problems that I had. So I've already talked about the first one is that because I decided to do this at least at first in multiple virtual machines, I had to finagle away to get data from one place to another easily. And eventually I got pretty good at it. I use SCP a lot. I use SSH a lot. I use SSHFS a lot. I even made a video about it when I discovered that. And then I found out that that was, of course, abandoned. So, of course, it was. I make a video about something and find that it's abandoned. It always, always happens that way. But the point is that I got really good at transferring data from one VM to another to my main machine. All these things, right? And it worked fine, but it was tedious, right? And I did research other options, so things like Samba and stuff like that. But that all that stuff is also a mess. And I also thought about just creating like a drive of some kind, like a P cloud drive or a next cloud drive or something like that that I could use that I could then access between the different virtual machines. But that was also kind of a mess. So at the end of the day, transferring data between them was very, very tedious. And what I ended up doing to solve that problem was I just stopped using multiple virtual machines. I just ended up with one. And this worked out well for a couple months. And I enjoyed doing it because it allowed me to choose a different distro than what I was on. So it allowed me to experiment with some distros and some desktop environments and stuff like that outside of my regular experience. So that was fun. But it also just kept the data pushing and shoving to a minimum. And I was just able to focus on transferring data from my main machine to the VM and back and forth. It was much easier and it was much less tedious. It was actually more enjoyable. The biggest issue with going down to one VM, of course, was just that I was basically just connecting to the Internet from one place instead of multiple places. And it just was not as secure as multiple VMs ended up, you know, early seem to be, I should say. So that's the biggest problem that I had. But the biggest problem slash mistakes that I made were all self-inflicted. So we'll just start off with this. And I think I mentioned this in another video where I will mention it in another video. I'm way ahead on video recording right now. So I don't know when I've talked about things and haven't talked about things. So if you hear me talk about something that I've mentioned in this video and it seems like I haven't made this video yet, it probably is because I haven't. It's going to be very confusing for all of us. But the point is that I've made some mistakes. So over the course of the last two months, I have distro hopped on my main machine quite a few times.  And that's usually the way things go. And it's one of the reasons why I've started the two year Linux challenge. I want to stay on a single distro for two years. And that's one of the reasons why it's because I got sick of distro hopping. And I actually want to put some effort into fixing things when they go wrong. But that's beside the point. The point is that I distro hopped several times. I went from Redcore, then to Arch, and then to Fedora, and then back to Arch, and then to open Suza, and then to Fedora. You get the idea. I went through a lot of distributions.  Now, I preach on this channel constantly about backing up your data.  And along with many other Linux YouTubers, regular tech YouTubers talking about the fact that if you are going to have data on a machine, you have to back it up. And in fact, you should back it up in multiple places and all this stuff, right? We've talked about this so many times. And I do a good job on my main machine. I have gotten to the habit of running a manual backup every time I do an update. I don't really trust a cron job to do it for me. So I do it personally. And I have an alias in my Bash RC. I just run it. And I've gotten to habit of doing it. But I didn't do it with my VMs. And I didn't do it with my VMs, not only once, not only twice, not only three times, but at least four times. And the problem with that is that my VMs all had data on them, right? I had data from work. I had data from the channel. I had my browsing data. I had all my apps set up and stuff like that. I had my SSH keys and all the stuff that you'd expect to have in a VM where you've actually set it up to actually do some work. And I didn't back them up. It would have been bad if I'd just done it once, but I did it at least four times. And I did at least one point when I was hopping try to back things up. So at least one of the times that I hopped, I tried, I didn't succeed, because it turns out that I don't know how to back up a VM itself. Now, I know how to back up the data on a VM, but I didn't really know how to transfer a virtual machine from one machine to another. I did eventually learn, but it was past the point of actually being worthwhile.  Now, like I said, if you're going to take one thing from this video, take the thing that you should always take back up your data, kids. Don't don't be like me. Back up your data because of those mistakes, because of constantly losing my data. I had a hard, I had a hard time justifying continuing to do it. And this time now, I've installed open SUSE, the time of week, I'm on the two year Linux challenge and add on with all the tediousness of transferring data back and forth and setting up a virtual machine every time I decided to do something. And all the stuff that went into this whole process, I've just decided that I'm done. Okay, it just doesn't feel worthwhile. Now, like I said, I did stick with it longer than people thought that I would. But at the end of the day, it just doesn't feel worthwhile. Maybe, like I said, if I were to able to completely do Google my life, I would feel like it was more worthwhile and I could just kind of stick in a single virtual machine and it wouldn't be that big of a deal. But as it is, I can't, right?  I'm doing pretty good here. I'm having a good time. I hope I'm entertaining some people at least. And I also have to have a Google account, which is something that I use for work. So I can't not do my work. I mean, somebody has to pay the bills and it has to be me. So the idea here is that there's that gigantic leak of data that just made the rest of it feel like if they already have all my data, why am I bothering with this tediousness? Now, that doesn't mean that I'm abandoning the idea of privacy altogether. So I'm going to start using VM more constantly on my main machine so that I can kind of protect the location data and stuff like that. I'm going to be signed out of Google as much as possible so that I'm not broadcasting literally everything that I do on the internet to Google. I'm going to install multiple browsers on my main machine. One of the reasons one of the ways I'm going to do this is through distro box so that I can kind of containerize things. So if I want to say use Firefox in a container, I can do that and that's much more containerized and I can kind of just blow away the container if I need to. So the idea is to take advantage of containers but also just kind of change my workflow in such a way where I'm not logged in. I've deleted cookies and done as much as I can to make my browsing experience private when I'm not signed in. Now, it's not going to be a perfect solution. I will 100% absolutely say that, you know, right out loud is that it's not going to be a perfect solution. There's going to be times where I go and do a Google search and I am signed in, you know, it's just going to be the nature of the thing. I'm not going to want to sign out. The biggest problem with having to sign out all the time of all my Google stuff is that the two factor authentication takes a little bit extra of effort to actually sign back in and that's paying the ass but I can deal with that. So the experiment with the VMs is over but that doesn't mean my privacy thing is my privacy goals have been completely abandoned. I'm still going to attempt something new in terms of my workflow in order to try to maintain some sense of privacy but I have to be realistic about this and I think that we all have to be realistic about it. When we're using online services that we have accounts for and even when we don't have accounts for them, it's just kind of the nature of the modern web that we have to be aware of all the data that we are basically giving away to everybody and their capitalist ideas of data collection. It's just the nature of reality, unfortunately and we can do as much as we can to mitigate that data collection and I will do but again, I have to be realistic and say that it's never going to be a perfect thing until I can sign our sign art at Google and never sign into anything ever again. You know, maybe I can go live in the woods. Luke Smith could possibly be my neighbor. Although many, many, many miles between us, you get the idea, right? It's just not going to be a perfect solution. Unfortunately, the VM thing just did not work for me. It just didn't. So that's it for this video. If you have thoughts on any of this stuff, you can leave those in the comment section below. I'd love to hear from you. You can follow me on Mastodon or Odyssey. Those links will be in the video description. If you haven't already, give this video a thumbs up. I'd really appreciate it. You can support me on Patreon at patreon.com's last Linux cast links for YouTube and Paypal will be in the video description as well. Thanks to everybody who does support me on Patreon and YouTube because we're all absolutely amazing without you. The channel just would not be anywhere near where it is right now. So thank you very, very much for your support. I truly do appreciate it guys. Thank you so very much. Thanks everybody for watching. I'll see you next time. Stay safe.


Today, I'm going to discuss my two favorite topics, cruelty and, you got it right, sadism. Why? Because my name is Sam Batnid and I'm the author of Malignan Self-Love, Narcissism Revisited. I'm a former visiting professor of psychology in Southern Federal University in Russia and I am on the faculty of CEAPS, Commonwealth for International Advanced Professional Studies, Cambridge, United Kingdom, Toronto, Canada, Outreach Campus in Lagos, Nigeria. So let's delve right into these delightful topics. Hamas has committed blood curdling, spine chilling atrocities when it entered the territory of Israel on October 7th. I'm not going into details, they're available online. The Israeli government has provided the foreign press with a 43 minute video of some of these indescribable acts and bragging about the acts by the perpetrators. However, Hamas is only the latest in an uninterrupted series of atrocities in the modern age in the last 100 years. We don't need to mention, of course, the Nazis everywhere, especially in concentration camps, but also in the Soviet Union, the USSR. The Allies in the Second World War, need I say Dresden, Hiroshima, Nagasaki. The wars in Yugoslavia marked by the inhuman cruelty of the Croats and the no less murderous sprees of Serbs. Kosovo, Rwanda in 1994, Ukraine currently, atrocities against civilians are an inevitable part of what is known as total warfare. In total warfare, there is no distinction between civilians and fighters because a civilian population can become a fighting force. On this bear of the moment, reservists and so on and so forth are civilians when they are not in the army. And so this distinction has been eroded to the point that today it is considered acceptable and legitimate, albeit criminal. It's a crime against humanity and a crime according to the law of war. But still, it's totally done. The United States has committed such crimes in Vietnam, in Iraq, numerous other locations of Afghanistan lately. This is done and we need to live with it. This is a fact of life. And all these acts, all these atrocities are cruel, but other is sadistic. And here I am, your favorite blue professor of psychology to the rescue and to the bridge. No, cruelty is not the same as sadism. Sadism is an art form. It is the art of pain. It involves creativity. It involves premeditation, imagining the acts before they are committed. Gratification, pleasure in inflicting exquisite pain on another human being or group of human beings. Sadism is often coupled with masochism, which is self punitive. It is a way to purge a bad object or inner demons, if you wish. Sad or masochism.  It's been first described at the end of the 19th century. And sadism has to do with conflating pain, hurt, blood, body parts, torture with pleasure. Deriving pleasure by denying someone else pleasure. Deriving pleasure also by humiliating and shaming someone else. Deriving pleasure by hurting someone else, not necessarily only physically. Sadism can be physical, and as we came to understand in the second half of the 20th century, sadism definitely can be also emotional, social, social, shunning and ostracism, or a form of sadism. Sadism is perpetrated today via social media networks. And so, sadism is about designing a strategy, a plan of action that drives another person to experience intolerable, unbearable, torturous pain. And then witnessing this pain with gratification, satisfaction, pleasure. In other words, sadism is a form of hedonism. It's hedonic, not unhedonic. Cruelty is something completely different. Cruelty is self-regulatory. Cruelty is a figment of narcissism. Cruelty is the infliction of excessive pain on another person. The pain could be again psychological, could be social, could be physical. And so, superficially, cruelty looks a lot like sadism. And we often say this guy is sadistic, when actually this guy is not sadistic, he's just being cruel. Because cruelty is internal. Cruelty is for internal consumption. While sadism is about pleasure, and similar to, for example, eating good food, or drinking good wine, or watching a great movie, or a great performance. It's performative, while sadism is performative, therefore outward oriented. The sadist definitely perceives the other person as an external object, and intends to annihilate the other person. To eliminate the other person's capacity to survive. That's sadism. The recognition of externality and separateness. Cruelty, on the other hand, involves internalization of external objects in this sense, it's highly narcissistic. Let me explain. Most acts of cruelty follow modification. They are in the wake of some public shaming or public humiliation. We become very cruel, having been humiliated, and shamed, and mortified, and disgraced, and shunned, and attacked, and criticized in public. Not all of us, of course, but many of us. And the vast majority of us engage in revenge fantasies, which, coming to the bottom of it, is a form of cruelty. It's imagined cruelty, it's fantastic cruelty. It's cruelty that's never carried out, never translated into actions in real life, but it's still a form of cruelty. And so revenge fantasies are very, very common. I would say that possibly everyone has experienced revenge fantasies having been humiliated, and shamed, and attacked, and criticized, and so on. So here's the first linkage. Cruelty is reactive. Cruelty is an external solution to modification, and I encourage you to watch my videos on modification, especially the work of Libby. Because cruelty is a reaction to modification, it could be described as a translation, a transformation of a narcissistic defense. The sequence is this.   Cruelty is intended to restore the grandiose, inflated self-perception that the narcissist, for example, has. Same with the psychopath, same with the borderline. So cruel people most likely have exaggerated narcissistic defenses, and they would tend to be anti-social. Another type of cruel person is the labile, the dysregulated cruel person. Borderlines can be very cruel when they act out, when they decompensate. Some of them become violent and aggressive. All these forms of cruelty are intended to restore grandiosity to its rightful place. The cruel person has an inflated self-image, regards himself as godlike, or at least has chosen special with exclusive access to the truth. So we find many cruel people who are moral, righteous, religious, or ideological, because they believe, they're firmly convinced that they possess the monopoly on the truth. Morality is a weapon. It can be weaponized by narcissists and psychopaths. Overrepresented in social justice, activism, and so-called woke movements and so on. Morality is a wonderful opportunity for the narcissist and psychopath to act or to misbehave with impunity. And so moral people, fundamentalist religious people, ideologues, people who are committed to ideologies such as, I don't know, Marxism, Nazism. These kind of people are grandiose because they consider themselves to be members of a select group, a chosen group. A group which is privy to some arcane, unique, amazing key to the universe. They are masters of the universe in this sense. Same goes for example for certain professions, medical doctors, psychiatrists, people in finance. They're the same. It's the same dynamic exactly. There is grandiosities that is the derivative of being a member of a collective, a club, being chosen, being selected, being again privy to information that no one else shares. We find the same attitude among conspiracy theorists. And so when this grandiosity is undermined, challenged, let alone destroyed in the process of modification, there is an urgent need to restore it because this grandiosity becomes intertwined with identity.  This becomes your identity. When you're modified, it takes your identity away from you. To restore this grandiosity identity, you become cruel. Cruelty is unnecessary. It involves excess. It's going beyond the pay, beyond the call of duty, beyond justice. That's what makes it cruel. And so it is a choice. It is a decision. It is a selection. You choose to be cruel. You don't have to. There's no need to be.  You're being coercive. It causes what Grunberger called elation, narcissistic elation, but not pleasure. Do not conflate and confuse narcissistic elation with narcissistic pleasure. With pleasure, I'm sorry. Narcissistic elation is what you feel when you passed an exam with flying colors, when you went to a job interview and got the job. When your girlfriend agreed to marry you, that's narcissistic elation. It's triumphal. It's victorious. It's restorative. It restores you. Pleasure is something completely different, as you know, because we all experience pleasure.  Pleasure is external. It's added. It's a veneer. It's not your essence. Now, narcissistic elation is essential because it starts in childhood according to Grunberger, the famous psychoanalyst. And so cruelty causes elation because it restores previous grandiose identity. And this identity relied on a sense of superiority which is the derivative of the belief that you're somehow chosen, select, privileged, with access, are denied to others. So, for example, if you're religious, you're likely to believe that your religion and only your religion is the truth. All other religions are either partial or mistaken.  If you are a racist, you believe that other races are inferior and so on and so forth. And you would engage in cruelty to demonstrate your hegemony, your dominance, your superiority. Coercion is a way to communicate your privileged position in the hierarchy of being, in the chain of being. And so cruelty sustains a narrative. The narrative is two-fold. One, I'm in a moral position to exact retribution to restore justice, retributive justice. I am endowed with the kind of values, information and language that empower me and legitimate my decision-making as regards to your fate, your life and your well-being. I am in charge of you because I'm superior to you and I'm superior to you because I know the truth and you don't.  It is my role to either wake you up, elevate you, enlighten you somehow, to punish you and end or to exterminate and eradicate you because you are an obstacle on the way to progress and it is retributive justice. Your very being is an affront to me, an obstacle, a hindrance. I suffer because of you. The cruel person says I suffer because of my victims. My victims make me suffer. They damage me. They hurt me.  There's a lot of conspiracy, paranoid ideation going on here, conspiracism. So they are my enemies. They are my persecutory objects. I owe it to myself. I owe it to cosmic justice. I owe it to my moral adherence, to my religion, to my ideology, to my value system. I owe it to humanity to confront my victimizers, my abusers, the perpetrators, and to right the wrong, to rectify the structure and order of the universe as I know it should be. And how do I know how the universe should be? Because I've been told by God. I've been told by prophets. I've been told by philosophers. I know. I know. You don't know. Says the cruel person. My cruelty is justified. All I'm doing is for the greater good. I'm making the world a better place. And yes, it involves quid pro quo, an eye for an eye, lex talionis. There's a victimhood. It's a narrative that is not only about retributive justice. It's not about only about competitive grandiose entitled victimhood. It's about a restoration of the world as the Kabbalah says, fixing the broken vessels. It's an act of redemption. Cruelty is a form of absolution. It's good for the cruel person, for the soul of the cruel person, but it's also good for the soul of the victim. Members of the inquisition, the witch trials in Salem in the 17th century, these people believed that they were redeeming and salvaging the souls of the poor witches or the poor converted Jews that they have executed and tortured in indescribable ways. So it's about helping everyone. Cruelty is about helping everyone and about making the universe a better place by reverting it to its pristine, virginal primary state. It's a cleansing. Cruelty is about cleansing. You can immediately see that it is very little to do with sadism because very often the cruel person suffers along with the victim. I know this sounds crazy, but this is a fact. Many cruel people, not all sadistic cruel people don't, but many cruel people do what they do because they feel compelled to do it. They feel there's no other choice. They feel the alternative is decay and decadence and decomposition and degeneration. They feel that they need to save the world, to save others, to save even their own victims, and above all, of course, to save themselves. It's an act of salvation, salvato. So the cruel person may even experience guilt and shame over his cruel actions, may even feel ego-dystonic about it. It's uncomfortable, tormented. We have the famous speech by Henry Himmler, the head of the Gestapo, the rice fear of the SS, telling his subordinates what you're doing is horrible.  We need to cleanse humanity. We need to save humanity from the Jews. It's a holy work for which it's a thankless work because it will never become public, never be known, and you are, in effect, crusaders, your saviors and rescuers of humanity. Similarly, we have confessions of executioners throughout the ages, including very modern executioners using the electric chair or drip injections. We have confessions of executioners who are like haunted and tormented and traumatized for life, but they say it's my obligation to execute people. It's my obligation to sanitize this wound. It's my obligation to destroy and kill. It's like necrotic tissue that needs to be removed. Similarly, if you were to talk to Hamas activists or to former Nazis, they all justify their actions using the argument of the greater good. They are all what we know in philosophy as utilitarians, and they all employ the lex talionis. They all say, you started it first. You provoke me to do it. This is reactive abuse. But of course, there's no excuse for abuse. Reactive abuse is abuse, period. It is as reprehensible, as reprehensible, as condemnable, as horrible as any type of abuse. Who started first means nothing.  And finally, cruelty requires the cooperation of the victim. An admission of vulnerability, of failure, of defeat, of hurt, of damage, of pain. In this sense, cruelty is a form of shared fantasy. If you are cruel to someone and they are indifferent, they couldn't care less, the cruelty fails. For cruelty to succeed and be recognized as cruelty, it is the victim that should ascertain that it is feeling bad. The victim should say, I am feeling subject to cruel and inhuman treatment. If the victim says, what? No, I didn't notice this. I don't care. I haven't been paying attention. Then there's no cruelty involved. Cruelty is a combined state of mind. It's a symbiosis, symbiotic state of mind, of the cruel inflictor of punishment and the victim of the cruelty. They collude and collaborate and they agree upon the cruelty. They say the cruel person, the tormentor, the punisher says, yes, I have been cruel because I have had no choice. I have been cruel because it's payback time. I have been cruel because I'm committed to justice and retribution. I have been cruel because it's a way to make the world a better place. And the victim of cruelty says, I have been subjected to cruelty. I recognize this as cruelty and it has had effects on me. It has had an impact on me. I'm devastated. I'm traumatized. I feel and so cruelty often provokes counter-cruelty. It's an arms race of cruelty who would prevail ultimately. This doesn't happen in sadism. Sadism doesn't provoke counter-sadism. Sadism doesn't depend on the other person's collusion, admission, confession or collaboration. Sadism is focused 100% on pleasure. Sadism is a form of self-gratification via an external object whose externality and separateness are the source of the pleasure. Cruelty, on the other hand, is an internalized construct, something internal. The cruel person feels that something is a miss, a miss. Something is gone or right. Something is wrong. And he needs, if he is compelled or she feels compelled to rectify it, to set it right, to restore it, to redeem it, it's almost a religious experience, cruelty. And so, in matters of public affairs and politics, we usually witness cruelty, not sadism, and that's why it's easy to stop it. Sadism can never be stopped. Sadism is a character trait.  But cruelty is situational. And when the situation is perceived to have been resolved, either via defeat or via triumph, then the cruelty stops. And the cruel person and his victim can then coexist, co-survive and even collaborate. This would never happen between the sadist and his victim. His victim is an eternal victim. The sadist is an eternal sadist. Okay, I hope I succeeded to cruelly clarify the distinctions between cruelty and sadism. And I wish you a non-sadistic, not cruel day, wherever you may be.


So, now let's take this statement and action it will with a del z bar and a delta v, this I can do. So, del z bar t z z of z and del w bar t z z w is equal to c by 2 del z bar delta w bar 1 over z minus delta w over z. In terms of set this to 0, we must be careful because z equals w is the singularity. So, we must be careful to scale it to 0 with z is not going to be. z equals w is the k. So, let's keep those things around. And we will, we are one of our singularities at coincident points. Okay. Now, the next step we say that from English observation, from different values of the initial theory, this thing is the same as del z of t z z z bar. And this thing is the same as del z z t z z bar delta w. So, what we get now is some, some statement about how the 2 point function, some evidence of the 2 point function of z z z bar and z z bar behave. We integrate it once with respect to z instead of w. That, that integral will reduce this z minus w to the 4 to z minus w to the 2. And you will get lots of factors. There is some statement which dramatically, even try to know factors, is grammatically t z z bar of z, that is t z z bar of w is like del z bar del w bar 1 over z minus w is the whole thing squared. Now, the whole thing squared, and we thought of it as del z del w of log of z minus w. Again, you try to know factors that change twice. So, what this thing is, is del square m of the factors, del square is respect to z and del square is respect to w of log of z minus w. Now, you see why it would have been so dangerous to just say this was here. Because del square of log of z minus w is not 0, it is a delta function. Actually, we are going to put a more, more square here. That is problem, that is a good thing. So, this thing is schematically like del square, del over square of a delta function, which is precisely what we want to show. What I want to learn, what I am going to convince you of, what I would like you to carefully work out for you, I think you will learn factors. It is that t z z bar of z times t z z bar w in flat space cannot be thought of as, you know t z z bar cannot be thought of as precisely the 0. It is something that is 0 expectation value. But it is 2 y function has non-zero contact terms. These non-zero contact terms determine what we know about the theory. And the impact is even like this, which then implies, which then implies that the 1 y function of the trace of the stress tensor in a background that is not flat but a little bit cold, is known as the bottom of this thing now. Go on and think about it at home and we come back.  You go and think about it at home. Yes, it is exactly. So, this is a corresponding thing to how we calculate. But yes, it is it. And if you just proceeded in a standard QFT, very unregulated, unregulated. It is a little subtle though for the following reason, that you must define T mu for corrects. Define T mu as the response of the partition function to a change in consumption. Because if you thought of, if you wanted to ask, what is, you might at first be asking how can I possibly do this calculation in the standard way of doing things. Because I do not have an operator to insert. You know suppose we are working with the free goes on theory for instance, the classical operator corresponding to T mu mu is 0. It is just 0 variations of motion. Since you know since it is not, as we say it is an anomaly and it is all in the measure in some sense. So, if you did it all correctly in some standard quantity thing, we did it, but you have to do it carefully, easier way to do things. Because it is very easy using usual techniques to get control of what T is doing. But then once you know everything about what T is doing, but if you are always an analyst, you know everything about what T Z Z passed. That is the basic point. I know the two point functions of T, T Z Z. Therefore, what is the basic one, the two point function of T Z Z. Exactly. Since we use the energy concentration. Yes. Is this some kind of statement that if it was not so with the energy concentration. Exactly. It is possible to set this T, this two point function to 0 exactly, but then you will violate it. It is a usual statement with an office. You do it. Right. If you are going to preserve some things, you must give up on this. But you often have the choice of what to do. But energy conservation means expectation value of just the divergence of that operator. Right. Energy conservation would not be violated. No. I mean we want, we don't want that. We want the whole board. The operators to do it. Yeah. Right. Yeah. What does it mean to do it? Yeah. If you, I mean basically in order to derive this result, all we have used is the statement that we can replace this expectation value with this. Inside the code. Inside the code. Okay. If that were not true, that statement were modified. You could modify that statement in a way. You set this, this, this is zero. Okay. But this statement follows from some, some requirement. Requirement essentially. That different model is an invariance of the, of the, of the theory to be a good symmetry. And that way we are going to treat as approximate. It's the usual thing. It's like we have a global and gain symmetry. You often run into a situation with anomalies where you are able to keep the global symmetry normal anomalies at the expense of making the gain symmetry anomalies. And you never make that option because the theory of gain symmetry anomalies is inconsistent. Same thing here. I mean the, the t, the 2.1 t trace itself is zero. It's not zero. But okay. So what? Okay. But theory is not. If you walk into an invariant, you're becoming one. Especially in straight theory. Okay. Okay. Fine. So this, this, I, okay. So go through this exercise. Convince yourself of the logic we used here. And what are the words? That's, that's the first exercise. The second exercise, um, maybe I should just talk about the last exercise. Okay. Maybe it's important. It's important now. I'll just talk about it in class. Okay. So we'll do this. And then next time in class, we'll finish up a general discussion of what the normal theory theory is. And then turn into a discussion specific. Very nice. Okay. Next time in class, we will also find that we will, in a very related, but similar, but in a slightly more conceptually interesting way, we will find the same result. We'll also talk about, you know, how, you see this was only step one of the exercises. You know, we found the trace of the stress tensor. We'll also talk about how the whole partition function of the theory is completely determined from the statement. It's done for the same future. Yeah, the Irish program. That's it. Let's put the camera off. Let's get into the discussion we want to have.
