Okay, so what we're going to talk about today is basically weight distributions. We won't do this in great detail, but I'll point out some users for it. And there is one very, very interesting property that connects weight distributions in the code and its dual. So that will be the main result that we'll look at. If we can prove it today, maybe not, but in general, I'll point out why weight distributions are nice. So let's begin with C, which is an NK binary code. I'll denote by A sub i, the number of code words will see the weight i. Is that okay? So that's A sub i. The number of code words of C would be, if you want a very mathematical looking kind of rotation, let's say a size of, let's say C in C, so this is A sub i. So you might wonder what's nice about weight distribution. So if you look at binary codes, linear binary codes, weight distribution kind of tells you what all the code words that are close to a particular code word. So if we take one code word, so if we take one code word, which may be, I denote like the star. So if we denote one code word, then, so to ask the question, how many code words are there at a distance one from it? There will be, I mean, how many vectors are there at a distance one from it? That will be N, right? There will be N vectors at a distance N from it, from one from it. I think this didn't come out quite as well as I like, so I could draw it again. So that's my code word. So now I want to ask the question, how many code words are there at a distance, say, i from it? So at a distance one from it, there are N vectors, but not all of them will be code words, right? But if I tell you that A1 is, say, 2, then out of the N vectors that are at a distance one from it, two of them are code words. How do I know that? Okay, so suppose this is a code word, and suppose I tell you A1 of 2, let's say, so for example. Okay, this is for example. Then, all the N vectors that are at a distance one from it, two of them will be valid code words of the code. How do I know that? Yeah, so you take the two code words of the 8i, and then add them to C, wait, 1, I'm sorry, it means A1 equals 2 means there are two code words of the 81. Take those two code words of the 81, and add it to the C. You will get what? Two other guys. Okay, so in a way, this weight distribution tells you how many code words are a certain distance away from a given code word. Okay, so that also tells you how many, how many ways you can go wrong when you make an error. Okay, so there are so many, so there are so many code words near you. If the channel adds errors, you can somehow get close to so many of these other code words. Okay, so the weight distributions are useful in computing exact expressions for probability of block error, probability of big error and all that. Okay, so that's one way in which you can use it. Okay, and there are lots of simple results you can talk about weight distribution, so I'll write them down. You'll see some of them are very simple and they tell you something nice about it. Okay, so the first result is that in 0, 1 to A0, 1 right, so any linear block binary code will have your all 0 program, and that all 0 program has weight 0, so A0 will be 1. Okay, and then you can say that AI will be 0 for I from 1 to D minus 1. Okay, so that's the other result you can say. Okay, so from AD onwards it will be non-zero and it will continue to be non-zero in various different ways, because it's difficult to predict what the weight distribution will be. Okay, so this is where the weight distribution will look. So let's take some very simple examples and then figure out what the weight distribution will be. Okay, so if you take, let's say the n from the wrong interpretation code. Okay, it has only two code words and one code word has weight, 0, another code word has weight, and also you can say that 0 will be equal to 1, A n will be 1. Another quick property is the code words, summation AI equals 0 to n will do what? 2 bar. 2 bar, okay, so that's the number of code words. So that's the other code word. So that's the quick result you have, so there are only two code words, so let's jump. Okay, that's the first one. Second result is by D minus 1 to D, what can we say about this game? Yes. Yeah, so A 2 I is going to be equal to n choose 2 again and that will be 2 bar I equals 0 to 1 to what? N by 2. N by 2, okay, so that's 1 by 2.  Okay, so the other code we can look at, so let's look at some arbitrary code. It's the code with parity check metrics. 1, 0, 0, 0, 1, 0, 0, 0, 1, 0, 1, 0, 1, 0. Okay, so as I tell you, code has parity check metrics. How do you find out the right distribution? It's not really, there's no real easy way to do it. Okay, for finding minimum distributions, there's no real easy way. So obviously for finding the right distribution, there will be really no easy way. So you have to just distort all the code words and complete the right distribution for that. Okay, so let's do that. Okay, so let's start with this. So the last few things are going to be 0, 0, 1, 0, 1, 0, 0, 1, 1, 0, 1, 0. Okay, the message bits are the last 3 bits. The remaining parity at the faraway of the parity will be, so it will be 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 0, 1, 0, 0, 1, 0, 1, 0, 1, 0, 1, 0. 0 1 1 will be 1 1 0 1 0 1 will be 0 1 1, 1 1 0 will be 1 0 1 and 1 1 1 will be 0 4. But okay, those are my 8 code words. Then from here, 1 is just write down a 0 a 1 etc. a 0 is going to be 1, a 1 and a 2 will have to be 0. Here we know from the tidal check matrix that the minimum distance is 3. So a 1 and a 2 will have to be 0, but a 3 will be 1. 4, right? 4. Counting is a hard problem, I guess. a 4 will be, okay. So you get 1, right? So you add it up, you get 8. So that's the, okay. So what about the dual of this code? So if I want the dual of this code, it's again got 8. The way I find the dual will be just do linear combinations of the rows, I think. Right? Linear combinations of the rows. So we do that, let's do that. 0 4 0 1 0 1. Okay, 0 1 0 1 1 0. 0 2 0 1 0 1 1. Then what else? 1 1 0. 0 1 1. 1 0 1. 1 1 0. 0 1 1. 1 0 1. Then 1 1 1. 0 1 1. Okay, fine. So what are the weight distribution of both? A 0 rows. So for the dual, we use A 0 prime. Just to denote the prime, so notation. A i prime is the size of code words in the dual codes, that's that. Weight of C equals. Yeah, just to differentiate. A 0 prime is 1. What about the A 3 prime? 4 and A 4 prime is. It's a curious little code, I know it's mostly related to a self-dual code. So is it self-dual? It's not really self-dual in the way I've written it down. So you can do some manipulation too. But anyway, so that's the weight distribution. This is how you go about finding it for the code and its dual. So even here, for instance, this is the code and this is the dual, right? So we can do prime if you like. Anyway, so that's the result. And it's very common to write instead of A 1, A 2, A 3 like that as a vector, people usually write it as coefficients of polynomial. So it's very common to do that. So that's called the weight distribution polynomial. And the notation, let me define that. It's actually mostly jargon, but still it gives nice results. So wc of x, y, basically summation ai, x power n minus i, y power n. Yeah, i goes from 0 to 1. The weight distribution polynomial for a code is basically a polynomial in x and y that are two variables here, not just x, two variables but x and y and it is basically coefficient is ai and the powers are x power n minus i, y power i. So you can rightfully ask, why do you need two variables? Why is it all n minus i, y power i? It doesn't really have any further information than just the information in ai. What's the point in all these things? It turns out there are transformations of these two variable polynomials which are interesting. In particular, there's a linear transformation which will take you from this polynomial to the dual state distribution polynomial. So that's a very powerful result. So that's called the McLean's identity. So we will see that hopefully tomorrow. But that's the main idea. That's why this two variable thing is very easy. So there's a point to it. We'll come to that soon. But let me write this in so many different ways for you just to see how it works. So the weight distribution polynomial can also be written in this way. Summation of the work. All the polynomials can see x power n minus weight of c y power weight. You see why this is equivalent to the previous thing? Every time the weight of the polynomial is i, I will get the x power n minus i, y power i term. How many of them do I have? I have a, s, and i. So it's equivalent to that. Both of these are exactly the same. So this is also a popular way in which this equation is written. Is it OK? So let's go back to our examples and figure out what the polynomial is. From an application code, we saw that a0 was 1 and an was 1, but nothing else in between. So the weight distribution polynomial is going to be x power n plus y power i. So the even weight code of c is equivalent to this. So c power n comma n minus 1, even weight code. What is wc power x comma i? It's going to be summation n choose 2i x power n minus 2i, y power 2i. I will have to go from 0, 1, 2, 4, and 2, 2 or f, n by 2. So another way to write it is basically instead of writing it like this, I can also do this. This guy will keep the summation over i even, 1, 2, y, x power n minus i, y power i. It's the same as that instead of going 2i, 2i, 2i. I'm just replacing it with i even. Do you know of any other formula for this? Summation is one way to get it. So one way to get it is to say, I do this and then what? Summation. Let's keep x minus y over power n. This will give you this formula, right? By 2. Yeah, that's right. So that's the direct way to do it. Think about it. So x plus 1 over power n is summation over all i, n choose i, x power i, x power n minus i over power i. That should be good. So x minus y is the same as that except that we have a minus 1 power i. So all the odd terms will cancel in the summation. All the even terms will double in the summation.  So you notice here, curiously, if you replay the x plus y and y by x minus y, you go from the y distribution polynomial of the original code to that of the do it. And this turns out as a universal fact. For any code, this is true. For the repetition and even rate code, it seems like a very trivial result. But it's true for any code. For any code, you can do this. I will prove that. I've not yet proved it. It's a true statement. But there's also a constant factor. And that will basically be the number of code words in the original code. So you divide by the number of code words in the original code, you'll get there. So it's a very non-trivial, interesting little factor. You can go from the rate distribution of the code to its dual by simply doing a substitution in this polynomial. So that's a very powerful result. So let's give one more example here. Let's just see how it works. So for this, I'm going to use the 743 hamming code. So what's the 743 hamming code? So you take the palpitate check matrix, take duals, 0, 1, 1, 0, 1, 0, 1, 0. Of course, you take it in this form. So let's try and figure out the rate distribution. So A0 will be 1. A1 and A2 are going to be 0. What is A3? Let me see. Is there any smart answer out there? So if you notice, you'll see A7 will be 1 here. What is A7 being 1? All 1's is a valid code word. So if I find A3, if A3 is some x, A4 will also be the same x. So 2x plus 2 has to be equal to... See, I cannot be any A1, A2, which means A5 and A6 is also not there. Because A1 and A2 are there, A5 and A6 will also be there. But that, you know, is not there because 7 is the code word. So only thing is A3 and A4. And if A3 is x, A4 will also be x. So 2x plus 2 has to be equal to 16. So x has to be equal to 7. So from there, you can conclude A3 will be 7 and A4 will be 7.  If you want that for very, very too many codes, the simple codes, if you want to find out explicitly what the rate distribution is, even for the 6-3 code that we had before, we could have used this trick. But let's see. I mean, if I want one surprise, it's good to do it the hard way. And then you see that. So this is a nice little trick you can pull for the Hamming code. So what happens to the rate distribution polynomial? So if you want the rate distribution polynomial for the Hamming code, so C is the 743 Hamming code in the rate distribution of x, right? Basically, x power 7, right? Corresponding to the 0, right? And then, 7, x power 4, 1 power 3, plus 7, x power 3, 1 power 4, plus 1 power 7. So what's the build of the Hamming code? It's a 1, 3, 4 code. But we know that the build of the Hamming code is obtained from the Reed-Miller code, right? So it has a very specific structure. So in fact, you can show the build of the Hamming code has the rate 0 code word. And then I think all the remaining code words will have rate 4. So I think there is some such property for the build of the 743 Hamming code. But anyway, so something like that is true for the rate distribution of the build. So if you want, you can go back and check this. So each of the three rows have rate 4. Do any combination, what happens? You still get rate 4, right? This plus this is rate 4. This plus this is again rate 4. This plus this is also rate 4. Then you add all the three also, you get rate 4. So the dual code has just one code word of rate 0. And then it has some code words of rate 4. So that's the nice thing about the build. And in fact, even here, it's a little bit more painful to check. Even here, the identity I told you before is true. Instead of x if you put, x plus y instead of y if you put, x minus y. And then you have to divide by 16 because that's the number of code words in the Hamming code. You will go from here today. Put x equals, x plus y, y equals, x minus y, divide by 16. You can try this if you like. You'll go from there, the distribution of the code that that efforts to do it. So it's a powerful little idea to go from the code word to x do it. And we're going to prove that. We'll start the proof in this class. Maybe we can finish it. We'll see if you don't, we'll come back and look at it. So that's the idea. So try this if you have some time. It's a bit of an interesting way to learn this. So in general, what is true is what's known as Napoleon's identity. And they succinctly stated as follows. The rate distribution of the code is 1 by size of the code, rate distribution of the code, and the rate distribution of the code. There are several other forms for it. If you use this, y times x power minus y and y power i, it's going to be equal to 1 by 4 c. y times x plus y, y minus y. This is the other form for it. The other form is summation u and the code in the dual. x power n minus y for u. Maybe I'll put a vector here. y power y for u. It's the same as 1 over the size of c. It's the summation over u1. The code c, x plus y, x power n minus y for u. x minus y for u. There are three different forms in which you can write the Napoleon's identity. Depending on what you like, one form might appeal to you more than the other. In some cases, some of them are better. Essentially, if you look at something like this, the relationship is quite clear. Remember, these are both homogeneous polynomials, all of them are degree n. The power of y goes from y power 0 to y power n. Once you equate the coefficients on both sides, you essentially get linear relationships between the A i prime and A i. The A i prime is opened by a transformation of y with some linear relationship. It's some simple transformation that you can do from 1 to 4. That's the idea of this fantastic result. This is a quite nontrivial result. It's very interesting also that the way distribution of the dual is actually controlled by the way distribution of the original code. We're going to use this in the proof. This is the fan that we'll use for the proof. The proofs can be done in so many different ways but I'm going to use some elementary ideas. There are also more general group theoretic notions which are used to describe the proofs in simple language. Depending on mathematical sophistication, you can do them various things in this. What I'm going to do is very elementary. First property was a lemma that's used to the proof here. It's a cute little lemma. If you have a summation like this, minus 1 to the power u dot v. U dot v is the dot product to be nu and v.  We have all the binary vectors. I'm just sticking to binary.  I'm going to take minus 1 to the power u dot v. I'm going to add all u and c. So it turns out there are only two different things that can happen. Either v is in the dual of the code. If v is in the dual of the code, what happens to u dot v for every u is 0. So minus 1 to the power 0 will always be 1. You will get size of c. This is if v is in the dual. If v is not in the dual, what do you think will happen? Based on similar results that we have seen in so many different contexts, v is not in the dual.  What do you think will happen? You will get 0 and 1. How often do you get 0? How often do you get 1? It's going to be equally often. So what will happen to the summation? It's going to go to 0. So this is the main lemma that's used in the proof. So minus 1 to the power u dot v has a very nice behavior. In sum that over, all u is in the code. Every v is in the dual or v is not? If v is in the dual, you get size of c. If v is not in the dual, you simply get 0. Because u dot v will take values 0 and 1 equally often. So there are various ways to prove such results. So there's one slick, percept-based method which I can quickly prove. I'm not going to do it. I'll just orally prove it for you.  You fix a v and then look at the subcode of c for which u dot v is 0. That would be the subcode. You can show us the subcode. It will be added. And then you can show it has only one other process inside c. So c will have equally number of values. So I was just approving it. So I'm not going to prove this lemma for you. It's a simple result. Try it. It's easy to prove. You can also try it using so many other ways. But do it one way or another. Is it okay? So if you remember this proof, right? So basically look at the set. So that's for all u dot c for subcode. u dot v is 0. So v is in the dual. Of course, v is equal to the entire c. That's easy to show. If v is not in the dual, you can show it has at most one other, only one other course. So you see the subcode.  So it works. So this set over the subcode put one other course. v is not 1. So of course, then this will have the same size. And there you can conclude. Very easily, often, 0 and 1. So that's the proof. I'm going to skip the proof for a sake of time. It's not really very critical. But that's the idea. There are no generalizations of this result in the group theoretic setting and all that. There is a more generalization of the result. So that's a good, more sophisticated. So how do we use this? So I'm going to start at the left-hand side there. And I'm going to use this result and get a summation over c. And then we'll see how to get rid of the summation. So let's start with... So this is proof for the material identity. So I'm going to prove that. So let's look at the summation. So let's look at the summation. So what I'm going to do in the first step is to prove it not obvious. But what I'm going to do is instead of restricting it to c, I'm going to take the summation over all binary n-tuples. So I'll keep the same thing. So if I do that, obviously it's not an equality. But to make it an equality, I'll use the previous lemma. So how do I use the previous lemma to make it an equality? So only when v is in c-top, I want this to be non-zero. So what do I do? Inside this, I'll put the summation over u in the code word minus 1 power u dot p. And then, of course, I have to divide by size of c. So you see, this is kind of like an inspired manipulation. So the final result, you can do is manipulation. So it's fine. I mean, it works out for this kind of dual. Do you see this? It is really easy enough equality to show. So instead of adding up only over the code words of the dual, I'll add a row, all the binary vectors. But then I will emphasize that only the code words of the dual play a role. I'll take minus 1 power u dot p, add a power, all u and c. I know only when v is in the dual, this will be non-zero. v is not in the dual, it's in graph v0. So I'll add a 1 by size of c to normalize that dual. Then you interchange the order of the summation here and you'll get closer to the first step. The next step is to interchange the order of the summation. So when you do that, there's no problem here. Everything is finite. So I can add up any which way I want. So I have 1 by size of c. Somewhere over u and c d. Minus 1 power. So I should keep the minus 1 also in size. Summation over v in 2 by 1 and minus 1 power u dot p. x power n minus weight of v, y power weight of c. You're okay? That's the summation. And this is the part that I have to simplify. And if I simplify, the result is true, which I said the result is true. Summation will have to work out to what? x power n minus weight of u times y power weight of u. Right? Yeah, x plus y. Sorry, x plus y power n minus weight of u, x minus y power weight of u. So everything works out right? The summation has to work out. That's the main point of the result. So we will show that this summation will simplify to that original result. If you have a challenge, try it. Try it overnight. The answer will be given tomorrow. Tomorrow I will show you how this simplification is done. If you want to try it, try this. I know it's an interesting way to prove it. It's not very hard, but you have to really work out and see what happens. Okay, expand all these things. Okay, so we'll stop here for today. We'll pick up somewhere in the next class.


Okay, Bola buddies, this is an 18 gallon tote of jewelry. I purchased it already in the bags. I have no idea what is in each bag. I literally threw it in a tote when I got it and have never gotten to it. That was about three years ago. So tonight we're going to start digging through these bags. I'm going to grab a bag and I'm going to sell it. Hope to see you tonight at 9.18 pm Eastern Standard Time on what not.


These cytokines included interferon gamma, tumor necrosis factor, interleukin 1 beta, interleukin 2, interleukin 6, interleukin 8, interleukin 10, and interleukin 17a. Furthermore, the study also found that individuals who had been exposed to SARS-CoV-2 but did not develop symptoms still had higher levels of these cytokines than those who were unexposed. This suggests that even if someone does not become ill, their body may still be responding to the virus. This article was authored by Cheyenne Martins Rodriguez-Gomez, Andrea Carolyn de Souza-Brito, Weynia Ferres-Parrera-Manfro, and others.


What's up everybody Jason from jazby's casebase.com We just sold out another one of these Donner's football hobby 3 box breaks number 10 2 ran teams East from 2023 Chasing some CJ straw guys. We haven't got a case it yet. So we're trying to get one here guys and actually Nick Nick up sold this out himself. So basically it's a personal and we're gonna roll the die to see which stack We'll do here for him. So one two for this stack three four for that one Five six for the left or right side. I should say So here we go Three One two three four the middle the meat it was and then I'll post another one up after this Good luck, buddy This is getting right now one time Right now one time. Yeah, it's out of their break didn't sell it. I would have done it before but It's Friday tomorrow, right? So it's all good. I'm kind of hoping that I find one more box I'm sure I think there might be one there in the show floor, but I don't know sometimes we sell these out pretty fast in store, too So I Was just like I was snooping around earlier when I seen that we had the discount. I was like, you know what? Let me go see if there's these boxes over there in the fanatics room. So I Went in there and I was like, oh shoot. There is somewhere here So then I just took them. It's like, sorry, Mike. I'm taking these right now Figure we can sell them on this side today Is anybody watching this straight in open right now? Sinner is just cooking no back right now, and it's not even funny dude like Sinner I guess hasn't lost a set at all on this tournament yet, and he's smoking no back right now First set six one and now he's up three one We'll let us know named That's one there to start us off tank Jacobs O'connell Tyree Wilson spends a minute James coach to the jersey number to 28 There's an autograph. I make it Third patch. Oh, there's two patches. I know it's not two patches The other one's coming up right here Passing the torch. That's kind of cool. Look at Aaron Rogers. John Amos 86 out of Rough gotta be there's some Zach Hertz Plain-Tune Raider rookie optic preview autograph A little bit of a sweat there though, I was thinking it wasn't gonna pop up JC horn Darren Waller Cedric Tillman, well, there's a case it unleashed Josh Jacobs for the Raiders So obviously doesn't mean there's a can be a downtown, but there wasn't a leech in here. Nice Jalen her chart. There's Super Bowl We're wrote to the Super Bowl and say quan Barkley. Yeah, dude. Yeah, I got something man We'll something I remember the last case. We were working on in Daunas There was a lot of really nice hits throughout the whole case like we had a Rogers autograph Well, so we hit I feel like we hit a lot of good rookies as well. I think the downtown there'd have been a B John too Oh, there's a redemption speaking redemptions Rogers was a redemption. Oh, we also got a Josh Allen redemption autograph to in the last case that I was working on It was pretty solid. So I mean Even though there could potentially maybe not be no more case. It's oh, I still feel like it could be a downtown Autographs should be pretty good. It's like autographs.  I'll see what we got here for you, buddy The champ is here. Oh, man. What if this is a good one? Oh, please let it be a good champ is here autograph please Harris haha, come on. He's Harrison.  I was thinking because it was a redemption the champions. Yeah, I was like dad. I'd be a pretty nice one. No, he's a great player I'm not one against him, but you tell me he can't sign no autographs, man They've got time on the bench while they're waiting for a kick to happen to sign autographs Come on. There should be no excuse Justin Tucker the goat is always live and on card for the most part too in product Now that's a true Hall of Famer right there though Gibson What is this a kicker's box? Daniel Carlson for the Raiders all pro Kings autograph for this one already All right, hopefully it's a nice ready rookie Mike Evans. I see Jay Stroud red press proof It's pretty nice Ooh redemption again. All right. Let's see if we can redeem ourselves. I better not be another Harrison butler I'll tell you that rated rookies autographs gold now Is that gonna be at a 10 gold or at a 50 cuz? So I double check rated rookie autographs Those are out of 25 actually so orange so blue and orange and gold rather 25 blacks at a 10 If I'm correct There's 77 of them All right, here we go, man Let's get something nice here. Give me something nice Something nice ended off 365 Nice Devon HM. That dude is a beast There you go, man. That's gonna be out of 25 So Devon HM gold rated rookie autograph So that'll be like a little up little preview to as well and remember out of 25 very nice, man He's a great running back There you go, man. That ends up the break right there. So thank you for purchasing this as a personal man I appreciate it except Devon HM there the CJ Strout Bucker unleashed case it now remember this look could be a downtown, but there was a case hit unleashed in this Rogers name it do one and clean two man. Thank you Nick. Appreciate you buddy I'll pulse another one up guys if you guys want to try running back tonight


Hello everyone. Thank you for organizing that you accept my presentation for this section. First of all, I wish to emphasize that current research has a very preliminary result. So, because a lot of, okay, step by step, I'll show you results and you will see that it's really interesting to consider about the origin of gravity in our region. And this is the region. Region is the Black Sea northern part was characterized by specific natural environment and therefore by diversity of primal life ways during the upper political period. There are the way of the different subsistence system as a result of different wave of adaptation. In this region, there are no mammoth-developing, no cave arts, no famous ballolithic Venus figurines. The cultural layers of the majority of archaeological sites are very specific. In suspended state, without floor, so it's very difficult to find the base level of cultural layer. And of course, with very bad presurance of organic. The problem, all these features and similarities and stone tools a lot separated this region like a special steppe zone. In 1960s, Petro Yefomenko and Pavlo Baryskovsky separate this steppe zone as specific area of development of the upper political culture, which was located between European glacial area and African Mediterranean region. This idea of existence of specific steppe region was not supported by Dr. Mariana Gvazdover and later by Dr. Galina Grigoryeva. They noted that all upper political sites in the region represented different technological traditions as well as culture and different way of their origin. Later, at the beginning of 1918s, Dr. Pavlo Baryskovsky clarified his opinion and he admitted that this historical cultural area, steppe zone, has such unformity of the stone tool kit. But subsistence and primal way of life was the similar for whole steppe region. By the way, despite the this clarification, the discussion regarding the steppe zone in the upper political is still being continued among the even modern archaeologists. So the argumentations of adherence that similarity of stone tools and the opponent consider flint tool kits are very different. The problem also considered the specialization of hunting, mostly by Bison. But opponents considered that find of bones of different animal species do not confront the specialization of hunting. And the same problem with settlement. But on the last 20 years, yes, last 20 years, the new technique of microstratigraphy by Dr. Natalia Leonova allowed to fix separate settlement episodes. And of course, the huge question, the term of occupation of this settlement. So, next, at the beginning of the 21st century, Alexandra Krotova attempt to synchronize the technocomplexes of the apocalyptic in the northern Black Sea region on the basis of calculation, calculating indexes of the main categories and types of tools by the famous method Sun V Board and Perot. And she made a definition for the 24 archaeological sites, including cultural layers, for multi-layered sites, and characterized data for three technocomplexes, Seletian, Orinyasian, and Gravetian. This data is applied for current research. But I tried to normalize this data because for network modeling, it's very hard to apply this raw data. So, the first stage of my research was to normalize data. For example, I tried to find the difference between this meaning and divide by one. So, it will be the data in the range from zero till one. And if we have the comparison between two nodes in green, it's very similar sites. And the red one is a very different site. So, and then I tried to apply. I'm looking for different, different software. And my colleague, data scientist, Lubovka Pustina, supports me that it will be very easy for archaeologists not so easy to apply Python and main libraries in Jupyter notebook. But Jupyter, it's very easy for archaeologists because it's helped to do not the code, coding work like programmers, but you're very easy to apply and add some, import some labs, libraries, pandas, math, networks, networks help to build the network and other one. So, the, for all sites of the, in our region, I calculate the node is the site and the ages is relationship in the indexes of technological indexes. So, in the result, I had the 171 ages between different ages between all sites. So, you can see here is 171 from one. Then, for all these sites, we tried to build a network and review. Of course, I should emphasize that the correlations between all sites, all the sites is different because of chronological chronological meaning. But you can see that, for example, Sagaidak for early stage period is absolutely different, very different from in other sites. And the same with Lisky site. So, this side of these two sites is connected with Orynesian complexes in our region. But it's hard to say about Muralivka and Zolotivka. If you see on the previous slide, it's pretty similar and connected with other regions. This is question, big question why Muralivka and Zolotivka is so connected. Maybe it's the question for further research. Maybe all archeological sites, epigraphy and epigraphy period are connected and was based on the ground of Orynesian origins. Because we have several hypothesis regarding the origin of epigraphy sites in northern Black Sea region. Also, very interesting data regarding the gravity and site Yamy. Yamy is typical gravity and site. But how Yamy is so similar with Zolotivka and Muralivka. It's also big question that regarding with origin of epigraphy in our region. Another interesting question regarding the gravitation in epigraphy sites in this region and how you can see as a result of a line of network analysis, Ambrosievka site is so different. But I also think about this why gravitation complex, epigraphy complex Ambrosievka is so connected with Valyka Akarja and Anetivka too. But on this graph, it's absolutely separate. Probably my idea that probably because of functionality of this site. Because Ambrosievka as you know, it's very famous site with base camp and kill site. We don't have such sites in our region except Ambrosievka. Maybe it's the question of functionality, not only cultural features. And then I tried to make build the network of whole sites, whole sites with gravitation features of two chronological stages, early and later ones. And I can found that on this steppe zone, we can see the cluster, different clusters of site nodes. Kamiena Balka, Kamiena Balka Odin one and two. And it's hard to explain why it's so connected with Minivsky Yartu, probably because of functionality too. And Ambrosievka, as you can see, it's also a separate site. But regarding to another sites of this region, yes, they show this very big similarity. And only for these sites we can say about the whole steppe zone in this region. But also I tried to analyze and on this data set, you can see the Minivsky Yartu, Kamiena Balka has crazy high similarities and how to explain it, probably because of functional. And Yanisol is very different from all sites because it's final polylethic period. And also I'm trying to analyze functional and cultural distribution, because we see the similarities here. It's typical for steppe zone, high connection and very similar connection between these sites. But how to explain this connection, Kamiena Balka and Minivsky Yartu, probably because of functionality. And also I analyze the final remains, because I do remember from the first slide that opponents said that a lot of animal bonds of different species we have in this region. But as you can see, the bison, bison horse and bison presented mostly on this mainly on this site. So my conclusion is, yes, I'm thinking about Gefi, I'm thinking about project. But I decided, yes, Python and GeoPyter will be very useful and easy to apply for non-computer science. So the main conclusion is that the early sites like Lesky and Sagaidak are very different, probably because of chronological distance. But during the middle phase of the upper polylethics, we can find separate cluster of the site. The next question for user research to explain, is it functional or cultural difference? And interesting observation regarding the origin of epigravation in this region, influence of Muralivka-type tradition of tool production, and influence of classical Yama-type tradition to tool production that supports the mixing hypothesis. So thank you for your attention.


Hello friends, welcome back. My name is Sushil Singh and this is continuation of Excel tutorial. So today I am going to discuss about VLOOKUPs. So VLOOKUP is a very important formula which is available on Excel. So what is VLOOKUP? VLOOKUP is an Excel formula which is used to get values from another or same Excel sheet on the behalf of any common condition between these Excel sheets. What it mean? Let's see here. So this is our scenario by which you can see it contains two different Excel sheets. First Excel sheet contains the data information of employee and second Excel sheet contains the information of department. So we want apply VLOOKUP between these two Excel sheets and we want get the output. In our output you can see we want one more column in our Excel sheet one for the employee information and we want add department name from department information on the behalf of department ID. As I have told you there is a requirement by which a common column should be available between these two Excel sheets and you can see here department ID is available for these two Excel sheets for the getting information from another sheet. So let's move to Excel so we can see how we can apply VLOOKUP and we will get the result. So here we can apply VLOOKUP. This is our first Excel sheet and in this Excel sheet you can see it contains the information of employee and this is our another Excel sheet where it contains the information of department. So we want apply VLOOKUP between these two Excel sheets and in employee we want department name as a additional column from department and on the behalf of department ID. So there is a requirement by which we are going to apply VLOOKUP. So this is our requirement on the behalf of we want get the data that column should be available always in left side and we want the data that column should be available always in right side. This is our requirement. If this will not be available then you cannot apply VLOOKUP. So we want department name so it is available on right side on the behalf of department ID we want get the department name so it is available on left side. So this is going to fulfill our requirement. So I am going to apply VLOOKUP. We can apply VLOOKUP on the behalf of there is two method to apply VLOOKUP. So our first method you can click on this insert function. When we click on insert function there is a lot of functions available. All the functions are available in our Excel. So we want apply VLOOKUP. So we can select VLOOKUP and then click OK. When we are going to click OK then you can see there is another window has been opened and in this window you can see lookup value. So lookup value should be that value by which on the behalf of we want get the data. So we want get the data on the behalf of department ID. So we have to select the department ID from our employee table and then go to our table array. Table array is our second table which is our department. So we want get the data of department name on the behalf of department ID. So we have to select all the information from department ID to that column by which we want get the data. We want our department name so it will label on second column. So we have to select first and only second column. If department name would label on third column then we have to select first second and third and then column index number. Column index number over 2 for this case and then range lookup. Range lookup is a optional parameter you can skip. I will explain the later in this video session what is the range lookup. For not time being I am going to skip. Then click on OK. When you are going to click OK then you can see there is a department name of sale is available. So department ID is 1 and then department name is sale and you can verify from department. So here department ID is 1 and then department name is sales. So it will going to result as it is we want. So we can scroll and we can see all the department name is available on the behalf of department ID from department table. Our second method you can type formula. You have when you are going to type formula you have to apply equal to then formula name. So I am going to apply we lookup then we have to select we lookup. Then it will ask from lookup value. So lookup value should be department ID from employee excel sheet. Then we have to put comma then table array as I have explained in our method 1. Table array we have to select all the columns from starting to by which we want to get the data. So this is our second position. So we have to select index value should be 2 and then third optional parameter you can skip. Once we are going to click OK then it will reflect the result. So this is our output and now you can see here as I have explained. So thank you so much for watching this video.


Hello, I'm Adam Mollinger and welcome back to part two of this best and worst Disney list. Did you miss part one? Do you not subscribe to Food Nation? I suggest subscribing now going back and watching that then coming here again. Why did I split this into three parts you ask? That's a fair question. Let's get started with number 30 on movie feuds. Disney turns out a lot of depressing stories and Dumbo is no exception. It's a pretty miserable affair to watch for multiple reasons. A cute little baby elephant cub is taken from his mother due to his Freakishly long ears. I know baby elephants aren't called cubs. Calm down. Then there's the scenes of slavery and racism on display. Our title character Dumbo befriends a mouse and they figure out a way to not Only overcome his large obstacles, but to make something amazing from them. The final shot of our little elephant cub snuggling into his mother's nose at the end warms even the frostiest of hearts. I'm looking at you Elsa. We love frozen here, don't we kids? Pinocchio is a strange and interesting idea. A wooden boy trying to figure out where he belongs in this topsy-turvy world. The premise was more than enough, but then you add in his growing nose when he tells a lie. It completely bonkers in very adult drinking section of the film. And then there's the big whale finale that would have even J.J. Abrams saying, That seemed like a bit much. Looks like dreams really do come true when you wish upon a star. Don't they Pinocchio? Sorry. Sorry y'all that you Pinoc. It's just the stars I'm wishing on must be broken. Because I've yet to wake up in the morning to scarlet your hands and make him be breakfast. The bare necessities of life will come to you. The story of a boy being raised by animals is nothing new. But the 1967 Disney animated picture does it in a far more playful and charming way.  Put this around the halfway mark on my list. The 2016 live-action CGI installment looks to be much darker, but we'll always have this classic to fall back on. You can of course also see some of the great animals pop up in the TV show Tailspin. And props to the TV show for making Shrikan a power hungry business type. Kind of a mogul if you will. I don't know what a mogul is. I think that's that's the right word though. If you listen real closely you can still hear the sounds of children crying as they're newly introduced to Bambi. But why would they be crying Adam? You ask.  We all remember. A foggy afternoon, a grassy knoll, chilling breeze in the air. The sound of a Winchester Model 70 rifle unloading a buckshot in the distance. A mother cut down in the prime of her life and her son forced to flee for his very well-being. We all remember! We all remember! We grow up with Bambi as he learns to walk, make friends with characters like Thumper and even fall in love. Eventually he will grow into a proud strong buck and the circle of life will continue. The son becomes the father and the father becomes the son. Superman quote. Yeah. Me Peter Pan! It's actually more partial to the movie Hook with Robin Williams and Dustin Hoffman. But the 1953 movie it's still pretty solid. That says a lot as there's been almost 10 versions of this movie on the silver screen with Pan being the most recent. The Lost Boys, The Pirates, and Peter Pan himself help carry you away from the real world and bring you into Neverland. I've also been confusedly turned on by Tinkerbell and that hasn't really changed. Not really sure that's something I needed to share with you. Right now be like Walt Disney Pictures bolt. This is probably ranked higher than it should be even on my own personal list and I'm sure some of you are insulted by where it's at. It's a well-made and nicely animated story that doesn't overstay its welcome. John Travolta voices the titular character Bolt with a nice spunky attitude.  It's a blast watching Bolt come to the realization that he's not a super dog nor does he need to be. The standout role goes to his sidekick Rhino, a hamster who loves to live on the edge. The ending is heartwarming and the message is nice and simple for kids. It doesn't take a super bark to be heard. As I reflect on my list in real time I've determined that this thing is just a total cluster. That these these movies could be moved around in any real order. It's really only the bottom of the heap and the top 10 that matter. Everything else is just kind of window dressing. I have fond memories of Winnie the Pooh and his crack addict level of obsession with honey.   Yes those are words I typed out on paper to read aloud to complete strangers. I have such a lack of respect for myself. Anything is really fair game. Tigger is the best of the bunch with his superhero ability to bounce higher than a kangaroo on coals. Fine movie for all ages, but it's really for the kids here. That was lovely. I listen Wonderland. I don't know what kind of messed up fever dream someone was on to conjure up this story. I'm not complaining. Most of the Disney films are based off previous works. Novels that were typically much darker. This movie's no exception. Adapted from a book that came out in 1865. How do I know this you ask? Simple. I'm the author.  He's essentially the bunny version of Flava Flave. It's a wild and visually intense narrative that doesn't rest from the opening credits to the final scene. God how many of these do we have left? I'm running out of verbs. Hunchback of Notre Dame. How is this so high on my list? I'm not even sure I like this movie. Let's make a note that I must have originally compiled this thing when I was drunk. Let's also note that I don't drink, which makes my previous statement all the more puzzling. The Hunchback of Notre Dame or Notre Dame, however the snooty pretentious people say it, follows Quasimodo in his quest to be accepted. This poses a few challenges considering this flick takes place in 15th century Paris. Women were only just allowed the ability to breathe there, so accepting some sort of freak show creature who leaves in a bell tower, that's asking a bit much. Hunchback features a great villain who sounds like a type of fat free yogurt. Frollo is not thrilled with gypsies, mainly due to the fact that Esmeralda shot down his vances on her. A man has never been this sexually confused since Tinker Bell got her own spin-off movie series. Yeah, we're back on this again. A female lead? A female lead who's not white? A female lead who's not white, who's not in the kitchen making food for her man who's coming home from a long day of winning? What sort of sorcery is this? It's a rare treat when a movie comes along that throws out all preconceived notions of what makes a film a success. Mulan is a fine motion picture with some great action. There is naturally a comical sidekick. There almost always is. This time it's Mushu, played by Eddie Murphy. Is it Mushu? I don't care. Mulan also has a solid ballad by pop diva Christina Aguilera. This has a lot of the typical Disney tropes, but it also has a very refreshing setting and lead character.   Take that pain, multiply it by a thousand. That was baby Adam's reaction to the ending of Fox and the Hound. What a miserable way to go out. The title is the story, a buddying friendship between two unlikely animals. There's adventure, comedy, thrills, and sadness. And the wounds have started to heal so I can talk about this as an adult without breaking down and crying about the film.  Why do you hate preciousness? Is preciousness a word even? My initial reaction to the Princess and the Frog trailer was an intense meh. Can you even have an intense meh? Meh. Second and third watchings made me appreciate Princess and the Frog far more. Plus it has John Goodman in a small role, so that it automatically bumps it up a few pegs. We follow yet another female protagonist named Tiana. I would have watched an hour and a half of her busting her butt to make her dreams come true.  It's all by the numbers stuff, but Tiana is so likeable that it's easy to watch. The Boogeyman is a cool bad guy too. The Prince annoys the crap out of me, but I can overlook it since we are in a unique setting, New Orleans, with great songs and a string of solid side characters. I just wish Disney would have dug a little deeper. One of Disney's prettiest animated films to date, if you ask me, and you did ask me, so I told you. Making Tarzan a Tony Hawk Pro Skater was an interesting tactic, and I think it paid off. Having Canada's gift to the world, Phil Collins' score the entire soundtrack might have been a bit much. I'm a Genesis Phil Collins fan, but a whole movie of his soft music gets a bit overpowering.  This has to be one of the more adult Disney pictures, especially early on when some crew members are locked in a portion of the ship and they meet their watery fate. Michael J. Fox leads the picture as Milo J. Thatch. He and a group of specialists embark on an expedition to find the lost city of Atlantis. The sharp visuals look fantastic, especially paired with some great action set pieces. Alien technology and a smoking hot princess are two of my favorite things. I don't believe she's even an official Disney princess, which is a shame because she's just fantastic. And she will be mine. Oh yes, she will be mine. Wayne's World quote now. A lot of quotes going on. A stellar follow-up that takes our explorers to Australia. A bit puzzling that it took Disney 13 years to make a sequel, but I'm not complaining. This time our two most detectives, not to be confused with that other one, are out to save a giant golden eagle from a poacher named Percival McLeach. Never, ever trust a man named Percival, they're all wrought into the core. I believe this was the first animated picture to use fully rendered CGI. How do I know this? Well I saw it in a user comment on IMDB and that's all the proof I need. This was a financial disappointment for Disney and a bit of a cult flick. One that you should definitely check out if you've missed it. Wish I was getting paid for these promotions. Well there you go, another group of movies down. Next time I'll be doing the top 15 and I couldn't be happier to get this over with. Are we even remotely on the same page with our picks? Let me know in the comments and make sure to subscribe to Feud Nation if you haven't to join me in the final installment of this Disney best and worst episode extravaganza. Which is how I'm referring to this for that one time only and never again. More than just reviews, this is Movie Feuds and yes I'm aware that Frozen has not been on this list yet.


Hi, I'm Quinn Nabrowski, academic technology specialist at Stanford Libraries and the Division of Literatures, Cultures and Languages at Stanford University. I'm one of the three co-founders of SUCHO, Saving Ukrainian Cultural Heritage, online. The first weekend after Russia invaded Ukraine, Anna Kias posted a tweet about a data rescue effort that she was imagining focused on museum cultural heritage, specifically related to the music collections that have been digitized. On the other side of the world, Indiana, Austria, Sebastian Maestrovich saw this tweet and had some ideas about tools that she could use, specifically the free open source web recorder software. And in California, I saw it too. And I also wondered if we could do more faster. And the three of us got together that Monday, along with a few other colleagues. And on Tuesday, we launched SUCHO, doing everything all at the same time, writing tutorials, setting up a slack instance, making a website. And in the first day, we had 400 people volunteer to archive Ukrainian cultural heritage websites. Now, this is the first time, as far as we can tell, that there's been an effort at this scale to archive cultural heritage materials, you know, digitally during a war. But it's not without precedent in terms of digital humanities, rapid response. And for more on that, I will turn it over to Alex. There are, of course, whenever we try to, you know, understand a phenomenon, there's many genealogies always to be drawn. That's more often the case than not. This one in particular is one is the genealogy of us coming together as librarians and technologists in the world of at least the academy. And it's something, and at least in the North Atlantic world, the specific United States and Canada, even more so specifically. About 2016, the way that I tell myself this story, but of course, again, like with all genealogies, there's always, you can always go further back, further wider, etc. Just one particular way of telling a story is that around 2000s, after Trump won, one of the things that Trump wanted to do, Donald Trump, one of the things he wanted to do was to, as part of his party line, was to undermine the EPA and the Environmental Protection Agency. And all of a sudden, servers where EPA data had been housed were under threat. And a group of librarians got together to do a data rescue of the servers creating copies that went to other universities in the United States and some servers sitting outside the universities. You can find this project and effort under hashtag that I rescued. And of course, now they have continued doing exactly that type of work, right? Trying to save our specific data sets. It's slightly different than the Sutra, which is going to have to worry about our guests. But this is very inspiring to many of us. And when the Eureka Maria hit Puerto Rico, in my place of work at Columbia University, we wanted to help out. We wanted to do something similar to that. We wanted to follow in that example. What we did was we organized a mapathon to help the Red Cross reconstruct the map of the island, which they will need in order to be able to deliver much needed aid to parts of the island that were very damaged. And we knew how to do everything, right? We knew how to set up a workshop or a pizza. We knew how to teach the workshop. And we were using in particular OSM's task manager tool, which is the tool that a lot of people use on the side of the Atlantic for this type of task. But we didn't stop there. One of the things that we tried to do then is other folks in our community, in our library and technologies and scholarly communities, they wanted to do something similar where we thought we would start talking behind the scenes, helping out people put together a little like here, the step by step of how you set it up. So just to help people do it faster, even though we all have the skills, it always helps when somebody does the prep for you. This is like a course materials type stuff, models for the posters and that kind of stuff. But so this kind of normal behavior online amongst us in our community actually can be leveraged here. Since March, we've had over 1300 volunteers, mostly from North America and Western Europe, volunteer to archive Ukrainian cultural heritage websites. Now we're defining cultural heritage really broadly. So libraries, archives, galleries, museums, but also other places where people experience cultural heritage in their day to day life. So things like children's museums and libraries, children's after school programs, and even fan fiction archives are all in scope for what we're looking for. We've had an open forum where anyone can submit a link. But we've also been looking for links in other ways we've used wiki data as a way to try to find museums and we've even had volunteers digitally walking through the streets of cities under attack, looking for the cultural heritage icon or the museum icon on Google maps. We've used a variety of different tools and methods for archiving sites. We send all of the URLs that we get to the way back machine and we have people checking to make sure that the sites are thoroughly crawled not just the front pages, but things two or three or more layers deep. We've also been using the open source web recorder tools as a cornerstone of what we've been doing, where people are using their own laptops, and a friendly, easy to use, you know, a system called browser tricks cloud that is literally as easy as filling out a web form. You can get a high fidelity archive of a site. There's also a browser plugin that you can use part of the web recorder suite, where you can manually click through sites that are highly interactive or have maps or other components that need human interaction in order to be fully captured. And using things like browser tricks cloud has also allowed us to bring in more kinds of volunteers. Many of our volunteers come from the library and museum world. We also have senior citizens who have retired and have time on their hands and want to help, and even children who want to do something to help Ukraine in this war. My eight year old son Sam really enjoys going through our giant spreadsheet and finding sites in areas that are, you know, particularly critical right now to be able to capture with browser trace cloud. Next, I'll turn it over to Anna for a little bit about her experience volunteering with soup show. Hello, my name is honor, I am a librarian for Russian and Belarusian collections at Harvard library. All Ukraine has affected me and not only personally but also professionally. And I'm sure it's true for anyone whose work involves dealing with slavic studies. And from the very beginning, I had this urge to, to do something to help, but what can a slavic librarian do, especially the one based in the West. The call for volunteers came out for this new project saving Ukrainian cultural heritage online. I decided to go ahead and apply, and I signed up, and my social slack invitation came on March 1, which means it was were just one week into the war. That was the most difficult time on the emotional level. What followed were three months of hard work, which were both exciting and hard ranging. And I learned a lot, and I met people from various countries and all walks of life, who are absolutely committed to helping Ukraine in any way possible, and to provide intellectual and informational resistance to the efforts by the Russian government to erase Ukrainian identity and its culture. As a librarian whose background is mostly in traditional areas of the various ship like collection development cataloging, but also curating born digital collections and web archives. I was thankfully able to find a reason so which are in which I could apply my skills and expertise. Currently one major area of such a work in which I'm involved is metadata. Plus, there are two curatorial sub projects, which I will also measure here. So the metadata work, one of the directions of such a work in addition to just web archiving entire sites is gathering data and files from major archive collections and adding them to an internet archive collection for easier discovery. Those files include images, data, text, and video files. When these files get archived, they get archived with partial or incomplete or inconsistent metadata descriptions. And so, our group in Sucho, which is led by Kim Martin and Anna Keyes, is working on creating and editing this metadata. We had to develop the metadata structure and then make decisions regarding description principles, for example, whether to use control vocabulary or free text. We decided to use control vocabulary based on the Library of Congress subject headaches, combining more detailed subjects into sort of wider categories. My duties in Sucho metadata work is to standardize the application of subject headaches. And to that end, I maintain a list of headaches to be used. Of course, the metadata work for a project of this scale, it's quite huge, is quite different from regular cataloging. It is being done by a group of volunteers who may not necessarily have had any type of professional cataloging training or library training, for that matter. However, since the material being archived so large, you have to work with people who are willing to dedicate their time and effort to it. Of course, some training needed to be done and training materials also needed to be developed. So this project is currently still underway. Another project that I'm involved in on Sucho at the moment is Sucho Gallery. That project is led by Anna Keyes. We create and make a gallery that will feature images, media text, etc., from Ukrainian cultural heritage institutions whose websites we are archiving. And the gallery will be publicized widely in order to promote Ukrainian cultural heritage through featuring some objects from institutional websites that we archive, but also in order to fundraise for the institutions for materials they may need during the war. We also have heard from some Ukrainian educational institutions and community groups both inside and outside Ukraine that these materials could be used for teaching and learning about Ukraine, and that they may otherwise be unavailable. I am actively participating in the development of the gallery concept, metadata structure, and content selection. And one more curatorial project that I'm involved in on Sucho has to do with building a collection of memes related to the Russo-Ukrainian war. The war brought about a real proliferation of these memes, and they are an important born digital ephemera and a primary source for research into the society's response to the war. And they touch on a wide array of issues from the general war progress to ridiculing of the enemy troops, describing the details of the diplomatic war work, and relations between the world leaders, the economic effects of the war, the propaganda and media in Russia, etc., etc., etc. Basically, any striking news piece becomes a meme the very same day, and any politician can become a character in a meme. Nothing, and no one is safe. The meme collecting is done by manual submission of individual memes via a Google form, and also by automatic scraping of some Twitter and Telegram accounts that are specifically dedicated to Ukrainian war memes, believe it or not, there are quite a few of those. So, with Queen Dombrovsky and Simon Wiles, we are working on the way to present this collection in an interactive way online that will make it accessible for both researchers and the general public. So, without my SUCHO Library volunteer experience today, I'd like to say that for me SUCHO has been sort of an ideal workplace where creativity reigns, decisions are made quickly, technical issues are resolved very quickly and effectively, and true collaboration is the rule of the game. It's kind of like utopia of sorts. However, behind all this, there is the poignant realization, you know, I wish there was no reason for this project to exist. I wish we didn't need to do any of this. But at this point, it feels good to be able to try to make a difference. So the work on SUCHO continues. Our ultimate long term goal here is digital repatriation. These aren't our archives to decide what happens to them and we absolutely do not want to be creating a safe archive of Ukrainian cultural heritage for people to study in the west while the country is destroyed. Our goal is to turn these archives over to the Ukrainian cultural heritage community at the end of the war, see what they need and help them use these archives as a way to rebuild. SUCHO is a strange project. Our best case scenario is for all of these archives to never be needed. Nothing would make us happier than to see that all the websites are still online at the end of the war, and everyone who built them and takes care of them is alive and well and ready to resume their work. And I have evidence that suggests that's not going to happen.  And the war is continuing. One of the things that is most disturbing right now for us working on SUCHO is seeing the Ukraine fatigue in the new cycle and especially with some of the tech companies that supported the project in their early days. This really is a moment of transition where the project is shifting from being an effort of individual people supported, you know, technically and financially by tech companies, you know, to a longer term partnership with libraries that have been ramping up their efforts and infrastructure and strategies and thinking for the long term in order to support Ukraine in this war. And so in the coming months, you know, we will be continuing our partnerships with libraries to mirror our archives with organizations like the German National Research Department of Architecture to provide some of our cloud services. And, you know, even if it's not in the news every night, you know the the war in Ukraine continues and SUCHO's work continues. We have many more sites to archive we're continuing to track memes we're working on the galleries. And we'd love for you too. Join us on our website's SUCHO.org. There is a form that you can sign up to volunteer and we have a waiting list right now but we're hoping to open it up to people in waves over the summer because there's still a lot to do. So thank you so much for your time.

Please ignore whatever is going on behind me. I don't think I can stop them. I think marbles is cleaning kermit So full disclosure I think today's video is gonna be a little longer than I would usually post on this channel a little more in-depth a little more Relaxed and that's because I hit like three major milestones on my channel in the last couple weeks I reached 16 million subscribers. I reached 2 billion views and this is my 300th video So today I'm feeling like very sentimental, but if you don't make it through the entire thing I just want to say thank you so much for supporting me and caring about me and Treating me like a human being for so many years now, and I just really appreciate it So people have been requesting that I do this for quite some time I was the tag that was going around for a little bit where people react to their old videos and I Really didn't want to do it for a couple of reasons The first of which is because it makes me absolutely cringe to watch my videos Don't like to watch them I don't watch them as a matter of fact We have a rule in this house when people come over and sometimes we like to sit in the living room and hang out and watch YouTube videos you're not allowed to watch other people's videos, which is a rule that Ryan Higa thinks is Hilarious to break just because it's so it's hard to watch yourself and it's like cringy especially if it's old just It's just weird man And the second reason I didn't want to do it was because it felt like the ultimate jumping of the shark That's the definition of your channel jumping the shark right you reacting to your old videos It just feels so meta and so ridiculous I got to thinking in my Sentimentalness then it really wasn't such a bad idea and then I guess I would like to do it I get a lot of comments a lot of times from people saying that they like my old videos And you know they want me to do things like I used to and every old video of mine I've watched the video sucks like half of them. I didn't even export them, right? Like they're wrong They're just so awful and then on top of that the subject matter is pretty cringe not that I do much better now You know everything I put up is a little questionable Reflecting back on the things that I've done in the past I just get a sense that I've grown up a lot and I hope that you feel the same way You know, I think I will always have a relatively immature sense of humor But I am certainly a full grown adult at this point, which I like a lot And what's that saying that every seven years or something all of your cells turn over so you're technically a different person I do very much feel like in comparison to the girl that was Uploading videos yelling and screaming obscenities. I am definitely a grown-up version of her Now's the time.  Just gotta watch some cringe. Here we go All right, I'm gonna go all the way back to what looks like the first video on this channel Okay This was a good video at the time, but I do remember exporting it completely wrong. So Everything's like pixelated. Oh man. This is brutal. I realize that a lot of this has copyright music And I don't really know what to do I'm not sure I can even watch it. So Jenna, what's your strategy here? You going all glazed? I mean these guys are veterans at this point. They're a very nice young girl with a very large trip on her shoulder And quite the strong Boston accent And Yet again, I mean that was my job to go have fun and make a video that day and export it And it's all pixelated. I'm still incredibly embarrassed and ashamed that This type of quality shot on a potato still exists on my channel So also just to give you a little backstory I started the channel Jenna marvels because my first channel was called J morey six six Which is my real last name and my mom was trying to get a job at the time And it was sort of ruining all of her Google searches because my YouTube channel kept popping up I think it was like 2009 or whenever I created the Jenna marvels channel was only because my first channel I had my real last name in it like a genius. So I want to go over to that channel and see what's happening right now This is on fire and so is the rest of the song There was a fire at my job and as a good employee. I put the fire out the fire extinguisher But can we just talk about this tan? I Was working at a tanning salon and I was just like this is a good look now to be fair I don't have any makeup on so it looks extra crazy. I'm less orange now Sometimes I still air out a little on the side of orange, but I am past this phase Thankfully because this is just I'm offended You know, I'm surprised that my face doesn't look like pure leather at this point like maybe a little bit But it really should look like pure leather Naughty look at his face He looks so young I mean again I don't know if I can even play more than a couple seconds of this because of the copyright and music because I didn't Know any better. I didn't know all of the rules of the internet before I started posting things to the internet How to trip people into thinking you're really good looking if you were born really ugly like me have no fear girl like that It looks like it feels like Doritos because it did feel like Doritos I mean at least I look a little less tan in this video, right?  I've come a long way. Those things are Demonic looking. I like to pop myself up. The voice is very jarring And I know that I still sometimes talk like that But I mean it's it's a lot if you could just dial it back like a bunch of notches It'd be really great.  It's a little funny. It is I would say the funniest thing about this video at this point is that people still don't know how to say that title They're like that video where you're like teaching people how to be hot. This is quite the title I don't really do clickbait. I'm just like the most descriptive title that I can make is what goes up there That video though is like it's so cringy. It's so cringe Why would you go in there when you have this giant living room all to yourself connected to you? Like this so There's a copyright ensign in the background. I can't even fully understand what I'm saying Like in front of us like someone was like I didn't like when she made fun of him by calling him gay But it shows how she's grown in the past few years as a person. It's very true I've said words in the past that just aren't okay a lot of my older videos like I said Some words that are just offensive I think having a comment section and always reading the comments has helped me a lot as a person You know kind of grew up and realize that I don't want to talk like that. I don't want to be like that I don't want to use the words that I use and I just stopped I'm pretty sure that I've only ever cried like three times on the internet I think one was when I got marbles one was when I got Kermit and one was when we got peach It like to me, there's some of like the sweetest happiest moments of my life So I'm like really happy that I have a video of them, but the video is so bad Okay, the only camera that I owned at this point was my laptop That was my boyfriend Jimmy in the background who had come with me The whole thing on my So cute Let's sound All right, I mean like looking back now I probably should have done a more calm job introducing them to each other But he was so sad the first couple days. All I did was cry Look how skinny Just to anyone that ever complains about me uploading videos of my dogs I mean, I've been the same since day one so five years ago. I made how to avoid talking to people You don't want to talk to again Really great title.   I don't work out almost every shot You can see my arm go like this towards the end because I'm stopping recording I don't even like give myself a beat to then cut it I get it. I know why people like it. It was silly and such a bad video now It's like not entertaining at all sort of drags on you get it. You make a goofy face. I Do you have to keep watching it the accent is killing me. She seems like a nice girl I get a lot of comments of people being like can you do rants like people that pissed me off at the gym? And then they'll go and watch this and like this whole video Kind of garbage Like I see a lot of people that do storytime videos and stuff now and I get it Like I've always gotten why people like to watch that. I'm just I'm not that angry Really, I would never at this point in my life think just sit down and make a video about someone looking at my Electrical, I think it's just a matter of perspective Maybe what I choose to spend my time thinking about because it's not really this anymore Like just by this first sentence though, I don't know who's watching these videos I'm literally saying this as like I post them to my Facebook page I assumed the majority of people that were watching it had probably been to my house or would come soon Meanwhile, it's like everyone that's watching this has not been to your house Would carry on Like during those shots on looking at the camera looking at myself In the laptop This wouldn't even be like a vine of this one So bad the internet has changed so much That was I feel like in a time on YouTube where anything over a couple minutes people just clicked away You didn't want to watch because people were there for short-form Entertainment and now you know you'd sit and watch an hour Podcast or more you can watch hours and hours the things on YouTube people really want to do that It's just another thing that confuses me and people are like make videos like your old ones I'm like what do you mean like two minutes of me doing almost nothing in a video that took maybe three hours tops To shoot and edit. I think I also had every intention of taking this clip out of my hair I just never did it. I remember shooting this video. I was done shooting it and editing it by like noon That was the thing though, you know, you could do a video in the morning and have it be done by noon And just upload it because it's only a bit long Okay, there's an example of me just saying bad words for the sake of saying that laughing out of pure embarrassment and also this face This was like the height of people really not knowing what I was doing or understanding and like having to explain to people Look up my YouTube channel and it would be like this and they Understandably would be like Jenna. I feel like you're throwing your life away. I'm like you might be right I've had recent requests of people being like, can you please make a video like magic? What is it about this video that you're looking for me to recreate? Was it just that I drew all over my face or was it like that it's a minute of nonsense? I think like my entire Life will be a cycle of me looking back and everything I've ever done being like this is horrible.  How do you mean you can watch which is a slot? Will Ferrell at any age with any hairstyle? You know choice word feel again. I've grown up a little bit from this video in particular I'd like to click away now if that's okay.   It's very scary and nerve-wracking to put yourself out there After I uploaded land shark was unfortunately one of those days drunk makeup tutorial if you haven't noticed I don't really make that many drunk videos anymore because everyone's just thinking them some alcoholic or like every Suggestion that someone was giving me was like get drunk be drunk That even bet you gotta get your eyebrows on this is the time when you can afford to take a break Just be like, you know what? I don't wear my eyebrows I totally get it like why it was funny and why people like didn't ask for me to do other things drunk But I've definitely beaten that horse This beat, you know, I'll still probably do them on occasion But it has been a conscious effort to not just make a bunch of drunk videos man I think I'm gonna end our trip down memory lane there I certainly feel like I've changed a lot as a person in terms of what I upload onto the internet You know, there's times where I look back and I'm super embarrassed or when people think that they might know who I am now Based off of things that I did, you know, even two years ago or less than that And it's just not a whole representation of me as a person. It's just been nice to grow and learn and It's mostly due to constructive Crisis and feedback that you guys give me and you know when I do things or say things that I shouldn't do There's always been people there to be like, hey, this is goofy and I get that you did this with the best of intentions But like you're obnoxious Can't help but feel a little bit sentimental about all of it six years on this channel and Almost ten years on YouTube as a whole It's been a big learning experience a big growing experience And I just feel so lucky and grateful and thankful that I get to continue doing it And then anybody still cares or you know listens to anything that I have to say. I just wake up every day I'm surprised. I want you to know how much it means to me how much I care about what you think and that I do try to do right and Make things that are funny and entertaining but never at the expense of people and you know I've said lots of things that probably shouldn't have said or made lots of things I probably shouldn't have made and there are many people that just decided that that was enough and that I was never worth Watching or listening to again, but for those of you that have been here with me and have grown with me It just it means everything to me And I just really appreciate it more than I could ever possibly tell you when I started out It was sort of just for fun and you know it slowly turned into something that I did for a living and changed my life and I get to just laugh for a living and Hope you can tell that I have tried to grow up. I tried to learn and I've tried to Do right by other people. I'm grateful for anyone that subscribed yesterday And I am especially grateful to those of you that have been with me Since I lived in Boston and have watched me become an actual adult and not a adult in training Thank you so so so so much for Just being kind to me and caring and Giving me a chance to learn from my mistakes and I will try to continue to grow and Learn and do things the best that I can in the future. I want to live on the internet I'm not in this to try to do anything else beyond the internet for as long as I can and I genuinely mean that and I always have I just think that this is the most fun most cool most amazing thing That I could have ever asked for and I just appreciate you know when I meet people in person and People are so nice to me I I can't explain to you how that feels people are just have been really wonderful to me and I'm just I'm really grateful if anybody watched all the way to the end of this video I don't know why I just want to tell you how grateful I am for your support and kindness For however long you've been here Um, it just means the world to me and I you know Sorry It's a lot There's no good way to end this video other than Thank you, and I will see you next week
