Welcome to dealing with materials data, we are looking at the collection, analysis and interpretation of data from material science and engineering. And we are in the module on fitting and graphical handling of data, we are using R to do fitting as well as plotting to understand data better. In this session we are going to look at calibration, fitting and hypothesis testing. Calibration as we discussed sometime back is very essential and it should be carried out periodically. After calibration is done typically calibration table or curve or plot is generated. And sometimes for doing this fitting is used, so you will have a material or some process for which you know what the reading should be and you will use your equipment and you will read what the equipment gives as the reading and the difference is to be corrected because we know the calibration material we will use that to correct. So when you work on a new material when there is a difference then you can correct for the actual reading. And for doing this typically one also has to look at the data and generate calibration curves or calibration plots. One example is for example calibration that is done in nano-identor if you are doing indentation experiments. So we will in our case studies look at calibration exercise to give you an idea of how it works typically it involves fitting and that is why it is in this topic. The second one is that we have been looking at fitting and we first looked at linear fitting and then we looked at cases where it can be turned into a linear form and fitted and also non-linear. For example we fitted for specific heat which goes as A t plus B t cube. Now there are functions that can be linearized we have already seen some examples for example it is exponential you can take logarithm and if it is exponential with A plus B exponential then you can take Y minus A and then take logarithm that will again make it linear. And if it is power law we saw one example that by taking logarithm you can make it a straight line. But there are also cases for example if Y is A X B plus X you can take 1 by X versus 1 by Y and that will be linear that is known as line weaver Burr plot. You can also plot Y by X versus Y or X by Y versus X and they also produce linear plots. The idea behind these is to just see that there is a linear relationship that exists after that you can actually do the analysis and find the parameters for the linear fit. One more example where you will see which can be turned into a linear form is the hall pitch relationship for the flow stress in materials which is related to the grain size through this 1 by root d relationship. Of course if you do the transformation 1 by root d as X then you get sigma is equal to sigma naught plus K X so this is the intercept and this is the slope. These 2 sigma naught and K are known as the hall pitch parameters and we will do one exercise. So we will take the data from NIST monograph and which gives yield strength as a function of grain size at 295 Kelvin. And the monograph also tells you that the hall pitch fitted parameters are 18.6 plus R minus 1.7 for the intercept and 112 plus R minus 2 for the slope of the hall pitch relationship. And the standard deviation in the flow stress itself is 11 MPa. Of course once you know these 2 errors it should be easy for you to calculate what the error in sigma Y should be. So this is something that we have already looked at but how do these numbers come about? So we will take the same data which was used to produce these numbers and generate these numbers for ourselves in order to understand how it works. So it is a simple linear fitting that we are going to do. So fitting as we have seen is done for several reasons. One is to obtain parameters when functional form is known. For example we are assuming that hall pitch relationship holds and then we want to know what is sigma naught K is so you can do that. Or to identify if there are correlations. So you can do all these transformations like take log or take Y by X versus Y or X by Y versus X and things like that and plot. And if they show a straight line then you know that the functional relationship could be of the form AX by B plus X for example. So you can do a fitting exercise and that is where plotting is very useful, graphical analysis is very useful because you can just plot and see and if there is a relationship that you see then you can try to find the functional form. Or if the functional form is known then you can obtain the parameters. And getting parameters from data and estimating the parameters of the underlying probability distribution is something that we have already seen. So this is done and so it is part of the fitting exercise. But fitting can also be done to test if the data supports a given functional form. So this is the hypothesis testing. For example you can take the data and you can ask the question is it true that the flow stress is related to the grain size as power minus half. So that is a question that you can ask and to test whether the given data supports this hypothesis is the hypothesis testing. And so for example you can ask the question fit the copper strength data will be get an exponent of D as minus 0.5. And this problem is the problem of hypothesis testing. So we are going to deal with this in greater detail not just for copper we will take lots of materials for which data has been collected by one of the researchers. It is available in the literature available for everybody in raw form to download and do the analysis. So that is something that we are also going to do as part of our case study in the next module. But for now we will at least see how to fit and if you assume that there is a given form can we get the parameters that is the part that we are doing now and we will continue doing in this session and the next. So hypothesis testing is something that we have already seen at some level. For example we said okay what is the probability that the mean will lie within some range. So you can also have a hypothesis that the true mean is this or it is in this range and then you can test whether the hypothesis is true. You can also make hypothesis about variance and test and you can test the hypothesis about means from different experiments. So it naturally leads to analysis of variance which is something that we are going to look at in this module in one of the sessions and from there it also leads to design of experiments and so on. So we will do design of experiments case study also in the next module. So for now what we are trying to do is to do the fitting exercise. So let us do that. So let us start R version 3.6.1 and what we want to do is the hall patch for copper. So let us just try to do this. So what is the process? We first want to read the data and it is in CSV format. It is copper strength grain size at 295 Kelvin in CSV format. This data is taken from the NIST monograph and then we are going to take the grain size and store it in the variable capital D. We are going to take the yield strength and store it in the variable Ys and small D is 1 by square root of capital D. So this is D to the power minus half and then we are going to plot D versus yield strength and we are also going to fit yield strength as a function of D. So the intercept and the slope should give us the hall patch parameters. So you can see that the data, the D versus yield strength is like this. So this is actually square root of the 1 by square root of the grain size and so you can see that it is like this. So we can try to see where the fitted line is. So the fitted line goes through all these points and so it does seem to follow this relationship and of course you can also plot the residuals and you can see that about 0 on either side the data is spread and there are a few data points which are slightly away but most of the data is between minus 10 or between minus 20 and plus 20. So you can see that the residuals is random or it looks random. However if you plot the QQ norm for example, you do not see a straight line so there is, there seems to be some problem I mean it is not, the error does not seem to be normally distributed. You can also look at the fit and of course you get 18.5 and 12.4 and you can call for summary fit. So it gives you 18.5, 1.7 and 112.3672. So if you look at the fitting parameters that was given by the monograph, so it is 18.6 plus or minus 1.7, 112 plus or minus 2 and in this case we see that, so we get 18.5 instead of 18.6 the error is 1.7 and that is right and 112 so that is 112 and 2 is the error in the slope of D to the power minus half that is. So we see that we get the parameters that is described in Hall-Petch but there is a problem if you want to know if it is actually D to the power minus half because the Hall-Petch relationship is like this. So the Hall-Petch relationship is like this and so if you want to know whether it is D to the power minus half, one of the things that you can do is to take logarithm of sigma minus sigma naught and logarithm of D and try to see if that gives you a factor of half and logarithm of k then will be the, it will be sigma minus sigma naught, so you take log. So you will have log k and D to the power some minus n, so you will have log k minus n times log D, so that the n should be half or minus half and k should be given by the intercept. But we do not know sigma naught, so we assume that it is a constant, so we just take, so we can just take the data and it is not quite complete but one can try and do this exercise. So let us say that we have D, so we take logarithm of D and store it as y and we store as x the logarithm of so we can see whether we can plot this and does it follow a straight line. And so let us try to do the fitting and the fitting is y, sorry x as a function of y, so fit 2, so the parameters are like this, so if you take exponential 4.9680, so that is 143, when we fitted we got 112, so the k happens to be 143 and y happens to be minus 0.3, so it is not minus 0.5, so it is minus 0.4, so there seems to be slight deviation, so you can also look at the line that you get, so we can look at the error, so again the error, so we called it fit 2, so let us do this again. So you can see that this is a line and the data is different, so this is slightly off of course, but if you look at the, so fit 2, so you see that about 0 on either side, this is again normally distributed, we can probably normally distributed, we can look at q, q norm. So this certainly seems to be, the error now seems to be normally distributed, but we, so we assumed that d goes as power minus half and we fitted and we got some parameters and as far as fitting goes that is good enough, because if you look at the list data, this is from several different sources, the data is not even from a single source, so if you look at the grain size versus yield strength and all the existing data can be put in one single form and within some 11 MPa plus or minus you can actually predict the yield stress, which is very good. However, if you ask a different question, namely that is the power minus half and try to do the fitting, you see that it is not so, certainly approximate because there is still a problem sigma minus sigma naught and we have not taken that sigma naught into account or if you assume that the sigma naught is 18.5 like we got earlier, you can do this exercise, you can try subtract it and then for the remaining quantity you can try to do k log d kind of fitting, log k plus m log d kind of fitting and find out what the m and log k values turn out to be and see if that actually gives you this functional form. But we are going to do it in greater detail in the next module when we look at some case study, so we will take Hulpecch as a specific case study and check if there is enough statistical evidence and any physical reason why we expect it to be minus half or could it be something else, so that is a question that we are going to look at slightly later. But this is a data that is available and there is lots more in this monograph, it also gives the yield strength as a function of percentage cold work and temperature and so on and so forth and impurities, concentration of impurities and so on and so forth. So, it is a good idea to explore the data and try to see if there are trends and for example, if the two data are correlated and questions like that one can ask and one can use fitting as the starting point for exploring the data further. So, in the next session, we are going to look at analysis of variance and that will bring us to the end of this module and then we will move on to the case studies module. Thank you.


Donald Trump is back on Twitter spreading lies about the real cause of the opioid epidemic here in the United States. So in this video, we're going to use one of his least favorite things, which are facts. What is up everybody? This is Chris from the Rewired Soul, where we talk about the problem, but focus on the solution. And if you're new to my channel, what I like to do is take a look at what's going on on Twitter or YouTube or just in society in general and just try to see what lessons we can learn from them. So if you're into that stuff, make sure you subscribe and ring that notification bell. So yeah, this morning I was over on Twitter just kind of catching up with the news and all that jazz and I saw a tweet from Donald Trump, but by the way, did you know I'm on Twitter? Follow me on Twitter and Instagram at the Rewired Soul, alright?  So his tweet said, 90% of the drugs coming into the United States come through Mexico and our southern border. 80,000 people died last year, 1 million people ruined. This has gone on for many years and nothing has been done about it. We have a $100 billion trade deficit with Mexico. It's time. Alright? And this is a live by omission. One of the things that he does is he blames Mexico because obviously he's trying to get his wall built, but the thing is that we all need to realize this opioid epidemic that we're currently in is not because of other countries. Yes, other countries do ship in drugs, but 90% of the drugs coming in are not from Mexico. They're coming from right here in the damn United States. So when I retweeted this, somebody commented and said, well, maybe he's, you know, just focusing on the other countries because they have been doing a crackdown here in the United States about prescription drugs that we're handing out. And while that's true and things have gotten better and I'm about to show you some stats behind it, the thing is, it's a live by omission because he's saying that 90% of the drugs coming in and here's the thing. Pharmaceutical drugs are drugs, okay? And they're responsible for a lot, a lot of the opioid deaths here in the United States. Recently, the BBC cited a study from the Lancet Commission on Global Access to palliative care and pain relief. This study showed the US gets 30 times more opioid pain relief medication than it needs. Mexico only gets 36% of what it needs. China gets about 16% of what it needs. India gets 4% of what it needs. Nigeria gets 0.2% of what it needs. So yes, this is a fact, okay? We get way more prescription opioids shipped to the United States and distributed than any other country on the planet by a huge margin. So when I make videos talking about Suboxone and other prescription medications, like it's just important to understand that we as Americans have been trained to believe that we need these medications in order to deal with physical pain, psychological pain, and I'm not saying nobody needs medications, but when you look at these statistics, like ask yourself a question, ask yourself an honest question. Do you believe that the United States just happens to have more people struggling with pain than any other country on Earth? So why is it that we're getting so many opioids in the United States and distributing them to people? All right, so what you're seeing on the screen right now are stats from the National Institute on Drug Abuse, all right? So according to the NIDA, there were 17,000 deaths from prescription opioids compared to 15,000 deaths from heroin. Most of the prescription opioid deaths involved no heroin at all. Most heroin deaths did involve another narcotic, all right? So one of the lies that we are being fed is that heroin is the leading cause of overdose death in the United States. This is not true. Prescription opioids are still the leading cause of opioid deaths, not heroin. You can also see here that many people dying from benzos, like Xanax or Valium, had opioids in their system as well. Now these are CDC statistics that show we are doing better, but it's still a major problem. Now, although these numbers are trending downward, the CDC also states in 16% of US counties enough opioid prescriptions were dispensed for every person to have one. While the overall opioid prescribing rate in 2017 was 58.7 prescriptions per 100 people, some counties had rates that were seven times higher than that. So think about that for a second. Think about how many opioids we are prescribing here, especially when you combine the fact that most people who get started on heroin were hooked on prescription opioids before they ever tried heroin. I'm a recovering prescription opioid addict and I was this close to getting on heroin just because it would have been easier access, all right? Nobody wakes up in the morning and they're like, you know what? I'm gonna try some heroin today.  So think about the people who are getting hooked on the medication. Then they can't get more of the medication. Now they go to the black market to get some. So now that we have evidence showing that prescription drugs are still the primary problem, you might be asking yourself, well, why do we keep blaming other countries? And I think we might have the answer right here from OpenSecrets.org. So the Democrats, their total contributions from Big Pharma are over $6.9 million and to the Republican Party, it's over $9.9 million. So is it any wonder that politicians like Donald Trump and senators and all of them are trying to blame other countries like Mexico and China for a problem because Big Pharma is trying to keep the drug addiction right here in the United States so they can be the drug dealers rather than other countries. So statistics aside, this is something that I witness personally every single day happening to people who are in my life. So one of my very good friends, he recently had a back spasm. And his back started killing him. So he went to the emergency room because his back was killing him. And they prescribed him morphine and fentanyl. Morphine and fentanyl, two of the most powerful opioids. Like when you hear the opioid epidemic, you obviously think of fentanyl. For a back spasm, they gave him fentanyl, okay? Fentanyl is like a very last resort pain medication. So when my friend was texting me and telling me about this because he lives in another state, I'm like, oh my God, they gave you fentanyl. And as somebody who has worked in the addiction treatment field, as a recovering addict myself, like I'm like, oh my God, like is my friend gonna get hooked on opioids? And thank God, thank God he's doing all right now. He didn't get hooked on the drugs. But if he had a genetic disposition to these drugs, he might have become an addict. So you guys, next year is the 2020 elections. And I want you to remember this stuff, all right? When politicians are telling you things like where the drug problem really is, like remember these statistics. All of the sources that I cited will be linked down in the description below. You can find all these sources as well, all right? So when people like Donald Trump are saying 90% of the drugs are coming from other countries, remember, most of the drugs are coming right here in the United States from doctors prescribing them to people and getting people hooked, all right? Now, something else somebody brought up on Twitter was using marijuana for chronic pain management. And I'm thinking about doing a video on that, comparing studies with, you know, marijuana for pain management compared to like opioids. If that's something that you want to see, let me know down in the comments below. Or if you have any experience with pain management and using something else like marijuana to manage your pain, let me know down in the comments and maybe I'll make another video on it, all right? But anyways, that's all I got for this video. If you liked this video, please give it a thumbs up. If you're new, make sure you subscribe and ring that notification bell.

In today's video, we announced the 150,000 subscriber special. It's all in this box. Mostly. On this channel, we have opened some insane stuff and especially for those subscriber specials. We haven't done one in quite a bit, like since 100K probably, but we've opened some crazy boxes like Legend of Blue Eyes, Retro Pack 2. We've even opened every special edition ever made and every pack ever made. Well, I hope you guys liked that last one because we're opening every pack ever made again. Inside this box is nearly every single pack ever made. There's a couple missing, like some of the newer ones, but we're gonna grab those as well. And I got it in a trade slash purchase on Instagram from MoYuki, I think that's how you say the name. I don't exactly know how to say his name, but he traded him to me, slash sold him to me. We're gonna check them all out in this video. But before we hop into it, we are gonna do a giveaway. I'm gonna be giving away this Brothers of Legend first edition box. Just make sure you like the video, be subscribed, turn on notifications, let me know. If you're excited for 150K, make sure to subscribe because once we hit that, we can get these opened and it's gonna be another insane video. By the way, if you haven't seen the first time we did this, go check it out. I'll have the link up in the description, pop it up on the screen. It was about two years ago, a little bit more than that. We opened every single pack, it was crazy, but two years ago, there were some packs that didn't exist yet and now we do have them. So we're gonna be opening them up as well. It's gonna be pretty amazing. Oh, and it looks like we actually have a giveaway, newer set packs plus giveaways. So let's get this open. So we have an additional giveaway to the booster boxes. So this is gonna be a pretty nice giveaway in this video. Make sure you guys enter it and of course don't forget to subscribe because I'm excited to do this opening again. Hopefully we will not forget to record at the end. I'm gonna have a backup camera this time and everything. I'm gonna be ready. We have a dualist pack, you say blister. This looks pretty cool. Or is that you say two? You say two, okay. So this has been added to the giveaway. So make sure you guys enter that. Then we have the newer packs like Bersa Destiny, Donna of Majesty, your brothers of Legend. I mean, a lot of this stuff hadn't come out last time we did this. So it's pretty cool. Battles of Chaos, actually all of this stuff I think. Yeah, literally all of this is from 2022 or 2021. So that's cool to see that stuff. We're gonna have packs just piled up in the background here. This is gonna be amazing. Oh yeah, and some of these actually weren't just single packs, they're like sealed products. So like this is the first edition Legendary Collection Yu-Gi's World. That's six, so very cool. This is like an insanely expensive product.  Now we've got some blisters. Like this is, this was extremely well packaged by the way, he put in absolute work. Cause he, this came out from Europe by the way. I think it's Europe. Yeah, pretty sure it's Europe. So it was definitely not a short trip and he absolutely crushed this packaging. Very, very, very, very respectable. And really this is really a testament to him just wanting to see this opening because like we kind of agreed on this a long time ago and he's been really patient with me like waiting and I still haven't even fully paid him or like traded him all his stuff yet. So respect for sending these over and I'm really excited about it. First edition Cybernetics Revolution and he's even got these sleeved up, which is pretty cool. We've got Duals Pack Chas and you say, we've given away one of these before I think. We've got the classic Dark Legends which if you guys have not seen the PSA video yet I have some Dark Legends stuff in the PSA return. It might be tomorrow when you're seeing this or it could have been yesterday. I'm not really sure. And then we've got the Forbidden Legacy. This is pretty cool. I don't really know what this has to do with anything because these are unlimited packs but either way, I'm still excited to have this. All right, this looks like this is gonna be DRO4. It's sealed up by itself. And by the way, DRO4 is Dark Revelation 4. This is actually one of the best Dark Revelation that ever came out and it only came in these packages I think. So it was like, you had to get the two pack of blister even if you got like a whole like special edition thing it was still in this. So this is a really nice pack, very expensive pack as well. Let me say that. Did you know that Mega 10 2022 pre-sales are out? Use my code MightyRuksen30 if you wanna get $30 off with Sasiata's link. It also supports me as well. If you haven't heard about the reprints in these 10s, they're reprinting Dark Magician Girl, Red Eyes, Dark Magician and Blue Eyes with new artwork. And they're also reprinting a bunch of new cards like Red Eyes, Dark Dragoon, Forbidden Droplet, Nibiru, Ash, Ghost Ogre and many more. So make sure you guys use code MightyRuksen if you guys wanna save $30 on your pre-order 10 and it supports the channel. So let's get back to the video. This next box has just a ton of loose packs. So we've got like Starpack 2014, Legacy of the Valiant, War of the Giants, we're out too. Hope you guys just enjoy seeing these like before we even open them. It's just so cool to like remember all the sets. Judgment of the light, there's the Chickalates pack, literally the best pack you can possibly get. We got the Number Hunters, we got War of the Giants. By the way, notice they're all first edition if possible.  We've got the Hidden Arsenal 7, Nine of the Stars, Starpack 2013, I'm getting excited for this. Cosmoblazer, first edition and Abyss Rising, first edition and I'm excited because we're like not that far from 150K. We're around like 141 right now. So only like 9,000 to go. Really should be fairly soon that we can do this if you guys hit that subscribe button if you're new. By the way, I looked at the percentage. You know how I have the 50% of you guys not subscribed and you guys were like, it has to be more than 50 now. It's actually 58% of you guys are not subscribed. So go down below and click that subscribe button. Yeah, that's just how it works when more people start watching like more of them are not subscribed. So we're out of break of the shadow. We got the Dimension of Chaos. Oh, High Speed Riders was actually crazy in auction series at one point. Clash of Rebellions. I've got a special edition of this coming at some point. So that's gonna be fun to open. Those are unlimited though. Dragon's Legend II, Star Pack, Arc V, Cross Souls. We've got World Legacy or World Superstars. The Secret Forces, Secrets of Eternity. We've got the new challenges. Where am I gonna put all these? I just thought about this. Dual Slime's first edition, Battle Pack II. We've got Primal Origin and we've got Dragon's of Legend first edition. That's pretty valuable. That was only one of the three stacks from that small box that I just pulled out. So we've got a lot more. We've got Pendulum Evolution. We've got Maximum Crisis, Star Pack, Battle Royale. We've got Fusion Enforcers, Raging Tempest, Destiny Soldiers, Invasion Vengeance, Dragons of Legend Unleashed. We've got the Dark Illusion, Shining Victories and Millennium Pack. Then we've got ourselves Battles of Legend Heroes or Relentless Avenge, Dark Saviors, Flames of Destruction, Star Pack, More Star Pack. The Legendary Duelists used to be valuable. Got all those reprints. So Stream Force also one that I was opening right when I got back into it. Duelist Saga is always one of my favorites to open. Spirit Warriors is pretty cool. Circuit Break, The Legendary Duelist, Season, well, not Season One, not Season One. Not even Number One. They just called it Legendary Duelist. That's it. It's so weird because every time you look up a Legendary Duelist's price guide, it brings up this one. Because it's like, oh, Legendary Duelist. This set, it's like, no, it's not. Code of the Duelist and Battles of Legend and Relentless Avenge. If we insult this pack, we will pull the firewall. It happens every single time. The cool part is like, the last time we did this, I had not opened a lot of these sets very much. We've opened a ton of a lot of these sets now because just so many videos that we've had. Dark Neo Storm, The Keen, what is this, Arena of Lost Souls, Infinity Chaser, Savage Strike. I've really not opened a lot of this actually. It's not that old, Legendary Duelist Sisters. This is kind of the same thing. I've opened some of the reprints, but not that one. Hidden Summoners, Sofu, Legendary Duelist, White Dragon Abyss, Shadows of Ahala, Cybernetic Revolution. Yu-Gi-Oh has a lot of sets. Just let me tell you. Eternity Code, we've got ourselves Secret Slayers. I got a booster box of this now. Very cool. Dual Overload. This set has been reprinted into Oblivion, unfortunately, just all the cards in it. Ignition Assault, we've got a Magical Hero, Dual Power, Speed Dual, Mystic Fighters, Chaos Impact, Mortal Destiny, Fist of the Gages, that's exciting. I can't wait. I almost want to rip this open right now. Scars of Battle, Heroes Revenge, KevinPull.BLS, and BLS is still valuable by the way because they just won't print it in low rarity. It's pretty crazy, which I mean, I can respect that. It's not that great of a card anyway, so keep it valuable. King's Court, we've got the Lightning Overdrive, Ancient Guardians, Ghost from the Past One. We've got Blazing Vortex. We've got Legendary Dual Season Two. Genesis Impact. By the way, if I miss something and you don't see it, try to let me know. The chances are you'll probably just missed it, but also if I am missing something, I want to know. So let me know even if you might have missed it. It's no big deal. It'll be helpful anyway. Rise the Duals, because then I'll double check to make sure I have a Battle's Legend Arm again. If we got a 10k out of one pack, can you imagine? Season One and then Two Chaos First Edition. That's still pretty valuable. What is it? What the? Oh no, am I gonna have to crack this thing? Okay, this is gonna be fun. Retro Pack One, it's in a slab. So this is gonna be fun to get out.  I've done it like five or six times ever. So we're gonna have to crack that open. This thing is heavy, dude. I kinda like this slab though. It's very nice for display, like it's super solid, but okay, that's gonna be a nightmare to actually get out. All right, we're really starting to get into some good stuff. Retro Pack's obviously good, but Return of the Duals. We've got our Hidden Arsenal. This is getting older. Epic Dawn. He likes to go over the order of Chaos. Hidden Arsenal Five. Photon Shockwite. Generation Force. Stream Victor. These might be in some sort of order. Actually, wait, are these in order? I probably should have been kept keeping these in order to be honest, but we're doing what we can. Then we've got the Star Strike Blast. That's a pretty rare set. Only comes in first dead actually. Duals Rev. We've got Hidden Arsenal Two. Shining Darkness First Edition. Absolute Power Force. Stardust Overdrive. Hidden Arsenal. Ancient Prophecy First Edition. Raging Battle First Edition. Crimson Crisis. Dualist Genesis First Edition. If we get a Ghost Rev out of any of these, we're gonna freak out. Light of Destruction. We've got the Phantom Darkness. Galactic, or glad he just sold. Tactical Evolution. Strike of Neos. And Cyber Dark Impact. Woo, lookin' nice. Some fire sets right here. And now we've got even more. We've got Power of the Dualist. Yeah, these are definitely in order. Shadow of Infinity. Lost Millennium. Flaming Eternity. Rise of Destiny. Soul of the Dualist. Oh man, Ancient Sanctuary. First Edition Invasion. I thought these were in a different box. DR3, wait, DR3? No, DR1 and DR2. Okay, so woo, some nice stuff there. Yeah, it's going in order because here's DR3. Here's our beginning one. Here's our beginning two. We've got Premium Pack. We've got Premium Pack too. Legendary Dualist Synchro Storm Light Edition. Okay, the Light Editions, we actually didn't open in the last one. So that's actually pretty cool to have those. Millennium Pack. We've got Dualist Pack, Ferros. Yeah, it's going back to kinda older ones. Wait, wait, there's two of those. Okay, I know the Light Edition. Okay, the Regular Edition. Battle City, Crow, Yusei, Kaiba. Yusei, Yusei. Okay, we've got the Dualist Pack. Yusei, again, literally a million of them. We've got all these Dualist Packs. Yeah, these aren't the most exciting. They're kinda cool, but yeah, there's not really a lot inside of them, but still a pretty nice stack there with some GX stuff as well. Next up, we have mini boxes of Gold Series. So we've got the Infinite Gold. That's beautiful. I also have another question for you guys. When we do the actual opening, do you wanna have all the packs laying out like we did last time? I thought that was pretty fun, and it's like, you kinda see like we got a lot coming up. Or should we like have it more clean because like I have a different setup now. I don't know if we can even show everything. I would have to probably switch the setup a little bit. Premium Gold Return of the Blink. I don't know, let me know what your opinion is if we should have the packs behind me while I'm opening or if they should just be like off to the side and I'm just going one at a time. Premium Gold, which we're going one at a time anyway, but yeah, you know what I mean. Gold Series, hot in mind. Ghost Shares guaranteed, very nice. Then we have Gold Series 3, beautiful. Then we have Gold Series 2009. Okay, I haven't opened a lot of that set. And then Gold Series, this one is really expensive now. So pretty cool to grab that. So all those Gold Series are really nice to open.  All right, and there are a couple more Golds, including the Pyramid Edition, the weirdest packaging ever. It's a big triangle. You guys can't see it that well because we're running out of room. Then we have a couple of Maximum Gold. We got Gold and then El Dorado. Then we have some of the random packs like Movie Pack, Power Pack A, Power Pack B, Secret Edition, Gold Edition, Regular Edition, The Movie. You know, just all this random stuff. The more Power Up packs, 2014, 15, 16 Megatons. And depending on when we do this, like some of the stuff might, like there might be a new set that literally just came out. 17, 18, 19, 20, 21. We got Rally Yellow Mega Pack. Oh man, all these Mega Packs are amazing, 5Ds. So I guess the Yu-Gi one, we're gonna have to open that box to actually get that one. Which honestly, I might just buy a loose pack and then keep that one for another video. Maybe we'll do that, I don't know. Then we're getting into some crazy stuff like TP-1, 2.  Astral Pack, wait, so where's Champion Pack? Okay, Champion Pack is just out of order. So I don't know if he just didn't have them in order, but here's Astral Pack, which is after Turbo. So this is actually the fourth one. The second one's Champion. So we got Champion Pack, one, two, three, four, five. Then we got six, seven, and eight. So that's all of those. So they did eight. So they did eight Tournament Packs, eight Champion Packs, eight Turbo Packs, eight Astral Packs. Then they did OTS like 45 packs. They're on OTS like 20 now or whatever. So Turbo Packs, we can pull some crazy oldies like Dad and Judgment Dragon out of these potentially specific sets. Speed Dual 1, 2, I think we need three. There's a third one now, we don't have that. So if you have a Speed Dual 3 and you see this video and you wanna sell it to me just for the video, that'd be great. Anything you see that I'm missing and you have it, hit me up, cause I'm definitely buying it at some point. OTS, we got to go through 20 of these four. Four is crazy. This is the one with a max seat, eventually. It took me forever to get last time. And we got the Astral and everything this time. So it's really, really nice. We don't have to worry about finding those again this time. It saved me a lot of time. He doesn't have 18 or 19, but I have both of those. So we're good. So we don't have to worry about Tournament Pack 18 and 19. We've got those covered. And here's the final box. This says the best box. Thank you, Ruxin, for amazing content. And thank you once again, Mayuki, is what I'm gonna say for trading slash selling these to me and holding them on, you know, for like six months, maybe not six months, but it was a lot of months. He's been planning it with me. So thanks a lot for doing that, dude. It's gonna be a great video. I'm excited about it. Last time I stayed up all night editing it. So we have editors now. So they're gonna be making some nice money on that. And the finale of every single pack. There's a couple missing, obviously, but we're getting those and doing all that stuff. But here's the finale of the last few packs. We're starting with the best. We have the Legend of Blue Eyes first edition. We have Metal Raiders first edition. We have Metal Raiders promotional pack, which we opened last time off camera because I had to recreate it because I didn't record it. Magic Ruler, Spell Ruler first edition. We've got Labyrinth of Nightmare first edition. We've got Pharaoh's Servant first edition. We've got Legacy of Darkness, Ferranic Guardian, Magician's Force. We've got Dark Crisis first edition.

That is kind of randomly in there. McDonald's Pack one, McDonald's Pack two. We've got a, I don't know what this is. No Noble Knights of the Round Table. I did not open this in the last one. A bunch of people commented that. So we got to open this. World Championship one, or 2011, 2010. Those are both nice. First edition Crossroads randomly in here. Not with the other ones. Shonen Jump Anniversary Pack. So I don't know whatever this other, I thought this was Anniversary Pack for a second. What was this? I don't know what that is. So that's cool. Shonen Jump Anniversary. And then we've got Elements of Energy. So we just put some like really nice ones there at the end. Like this is gonna be absolutely awesome when we do this. And we're really, really close at 150K.

All right. Hello, everyone. My name is John Hammond, and I wanted to continue a last video that I uploaded on the local capture flag competition that I put together for my schools like Cyber team is practice and as an exercise learn a little bit more about the simple CTF skills and stuff So base base was the name of the next challenge that I put together and it's really simple It was a picture of Shiba Inu Doge and the prompt being he's so cute. Maybe he has something to say and This actually isn't a secondography challenge But I guess to suppose a little bit of it and that you have to like look at the metadata the hint here Is it have you ever heard of X if tool because I use that or at least I recommend using that to look at the metadata of the File and that was again It's something that some of the newcomers either don't know or have never seen before So I wanted to showcase that to them and and let them know that that chat that that tool Exists so for demonstration purposes. We can totally get the flag. I had just downloaded that image and saved it and You would end up running exit tool on Simply the file and it gets all the information for you and the comment is a special thing to notice because that is in base 64 you can see that right here so Super simple super easy. It would just make sense for us to Base 64 decode that so I will go ahead and echo that Into base 64 dash D to run that in the command line and we get our flag Again insanely easy. You would see J the best base is the base 64 So go ahead and enter that as a flag and get our 75 points nice So the way that I ended up cooking that was that I again, I'll open sublime text To show you this code And what I ended up doing was I downloaded The file just a picture of Shiba Inu off the internet So this URL is something that I just found by like literally Google image searching like doge and This should be in your dog So it saves it as the file name and then it goes ahead and it takes the flag variable Base 64 encodes it. I actually had used for iron range for another challenge So this code is actually duplicate for a later challenge where I encoded the flag multiple times that have to keep base 64 Decoding in base 64 decoding, but since this only iterates one time You really don't even need this and that could actually just move to the very front This doesn't need to be inside of a loop But that's how I ended up writing it at the time and then I actually just call exit tool to write the comment to be the new base 64 encoded flag and I call this with sub process the module in Python 2 like call invoke other programs and I have to split it because as a shell it needs to have those arguments in the proper order so Again pretty simple thing. I just steal this image off the internet and Then slap the metadata of the comment to be a base 64 encoded version of the flag super easy So our simple one-liner get flag goes to scrape out the comment section grabs the value and then it base 64's It's output just like we did essentially in in in our terminal demonstration So not a hard challenge by any means but again wanted to showcase the exit tool for newcomers that haven't seen it before So that was how simple that previous challenge was but it got us on the board and stuff Okay, thanks for watching guys. I hope you're enjoying some of this You get to see for one thing a challenge and a solution and the creation of that challenge So please let me know if you want to see more of stuff like this Or I should get into more in-depth stuff because I definitely plan to right now This is just the beginner level stuff for the newcomers on the team. So thanks again. See you soon


Hello fellow followers of Christ and welcome to the show that introduces you to the men and women behind history's greatest works of literature. Come along every week as we explore these renowned authors, the times and genre in which they wrote, why scholars praise their writing and how we as Catholics should read and understand their works. I'm Joseph Pierce and this is The Authority. Hello and welcome to this episode of The Authority where we are going to be looking at another anonymous poet, an author about whom we know very little but who wrote one of the most important poems of the medieval era in English at the Arthurian romance Sir Gawain and The Green Knight. So we'll be looking at this a we don't know much about him except that he was writing in the Mercian or Mercian dialect so that's the West Midlands. His contemporary of Geoffrey Chaucer and Chaucer will be the authority that we will be discussing the next episode. So he's a contemporary of Chaucer so living in the late 1300s so the 14th century but whereas Chaucer's based in London and it's associated with the court and diplomacy and should we say the inner corridors of power and therefore the Chaucer is very open to the new ideas in poetry. He's speaking in English which is much more frenchified. We'll talk about the well perhaps we'll do that now that the English language went through a transformation with the Norman conquest in 1066 so we looked at a few episodes back at the Bear Wolf poet and that's Anglo-Saxon England from when the Romans left in the 5th century to the Norman conquest in 1066. Well the Normans were as their name was suggest Norse men so they were Vikings from Scandinavia but they settled in what is now called Normandy in northern France and over a period of generations no longer spoke Old Norse and spoke French so by the time that the Normans invaded England in 1066 they were French speaking so what happened after that is that the language of court the language of nobility the language of the aristocracy because the Norman aristocrats replaced the Anglo-Saxon aristocrats for the most part so that the the language of the higher echelons of society became French and it was only if you like the lower echelons of society the peasants and the common folk who still spoke English that you know the Anglo-Saxon old English and it would actually be around the time of the Sagraine poet and Chaucer late 1300s before an official opening of Parliament was done in English not in French so for that there was 300 years of this if you like two-tier language system Chaucer is Anglo-Saxon by descent not French but he speaks a version of English where these two languages are now melding so Chaucerian English is this melding of the Latin and French and the Germanic English halves of the language coming together and that's why Chaucer is called the founder of English poetry and even sometimes the founder of the English language the father of the English language of the father of English poetry we'll talk about that perhaps more next week when we get to Chaucer however away from London away from court the different dialects were much more Anglo-Saxon so whereas we can read Chaucer in perhaps with difficulty but a modern English speaker can read and understand Chaucer with a modicum of effort we cannot read the Sagraine the Green Knight poem even though it was written at around the same time which is why the the edition that I have here is translated by a certain J.R.R. Tolkien from the Middle English of the time which is again much more rustic much more West Midlands dialect than Chaucer's proper spoken or written English so the other thing about it is that because it's the backwoods in some sense it's also backwood in the sense that it has much more in common than the Anglo-Saxon poetry such as Beowulf that we looked at where the poem is not written with regular meter and rhyme as per the the fashion in court and the fashion the renaissance in Europe but as with the Anglo-Saxons with alliterative syllables and stresses rather than counter syllables and rhyme schemes so it's not so much about the number of syllables per line as the number of stresses per line there's a lot of emphasis upon alliteration rather than rhyme so this is a different style it has much more common with the Anglo-Saxon past because this is closer to the Anglo-Saxon culture than the French-ified culture of London. All right so we're going to go into the poem to see again how profoundly Christian this poem is and we also see how it's part of a living heritage of Western civilization so the poem begins with a connection with ancient Troy so he see the poet keeping the tradition obviously the Iliad's about Troy the Odyssey's about Troy and then the Aeneid by Virgil is about Troy so it's as if we go out we need to and there's even allusions to him in Beowulf so let's look at this how the poem starts when the siege and the assault has ceased at Troy and the fortress fed in flame to firebrands and ashes the traitor who the contrivance of trees and their fashioned was tried for his treachery the most true upon earth it was Aeneas the noble and his renowned kindred who then laid under them lands and lords became of well nigh all the wealth in the Western Isles when royal Romulus to Rome his road had taken in great pomp and pride he peopled it first and named it with his own name yet now it bears so this is a poem actually about King Arthur's court but it begins with connecting this poem or basically this day and age with the past so with Troy with with Aeneas and then through Aeneas is descendant with Remus and Romulus with the founding of Rome so this whole work is part of that enfranchisement of the debt they saw the proxy of the dead enfranchisement the unborn this living tradition of Western civilization that this Arthurian poem about King Arthur in England begins with a reference to Troy to the very roots of Western civilization and by implication Homer and by ad by explication a reference to the Aeneid of Virgil so we have this living legacy connecting Aeneas to Arthur now it the story begins and we talked about this when we talk about the Beowulf poem and in Dante that how dates are used to signify so in Dante's Divine Comedy of course you know that the story begins on the holy Thursday Dante descends into hell on Good Friday he ascends out of hell into the starlight of God's creation at the foot of Mount Purgatory on the morning of Easter Sunday and then ascends Mount Purgatory and then into heaven during the Easter Octave well here the story begins at Christmas tide and the turning of a new year so again we have a we're already if we gotta get our allegorical and Tane twitching thinking okay whether he's the this is probably a significant to the the what's happening in the story and the liturgical year and the theological significance of the liturgical year now the King Arthur's Court in the middle of these festive Christmas New Year celebrations are visited by this mysterious stranger the Green Knight who described in Tolkien's translation as the mightiest on Middle Earth again the word Middle Earth the Tolkien uses goes back to to to these early times the Green Knight accepts a challenge so the Green Green Knight Green Knight announces a challenge to King Arthur's Court or to King Arthur and his court by extension that he would allow his head to be laid to be cut or to be struck by an axe and then if that wasn't fatal then the whoever does it would have to lay his head to be cut off by the axe so it's a trial to the death he would seem and there's something weird about this so good this this Green Knight and everyone is fearful of of of of taking up the challenge because they sent some magic involved some some mystery something supernatural so that even the other bold knights of King Arthur's round table are too cowardly and in the end King Arthur himself says well I will take up the challenge and it's then that's to Gawain in his humility accepts the challenge and this is worth reading he says yes I'm waiting that the King should should should face a challenge when he's got these knights says I am the weakest I am aware and in wit feeblest and the least loss if I live not if one would learn the truth so we're here so Gawain here humbling himself this is a man who has humility who sees himself I'm the weakest I'm not I'm far from the smartest on the contrary probably the dumbest and therefore I'm the one of the least missed I'll be the least loss it should should I die by accepting his challenge so he is his loyalty to his King and his humility which if you like is he's defining characteristic as the story begins the name the magic does begin because so Gawain strikes truly with the axe and the Green Knight's head comes tumbling off rolling across the floor and has even moved even descriptions of the head being sort of kicked away like a football by as it rolls across the floor by people but then the headless Green Knight this mysterious supernatural knight walks over and picks up his head I don't know how he managed to see where it was that's a quibble and then and then holding his head in his hand he basically says that okay I fulfill my side my my side of the deal now your side is that you will have to present yourself to me this time next year to basically to put your head on the block for me to use my axe on your head so then to Gawain lives for the whole of that year knowing that the end of the year this is the fate that he must that awaits him and then more significance it's on it's a Gawain begs to leave to go on his quest to find the Green Knight because he doesn't even know where the Green Knight is it's gonna be like looking for the Holy Grail you're gonna find the the the palace the home of the Green Knight but he begs to leave on all Hallows and other words all Saints Day so again significance right this story begins at Christmas a new year he's gonna set up in his quest on all Saints Day where he asked to leave and all Saints Day but he leaves the next day having gone to it goes to Holy Mass before he sets off so it's a pilgrimage he sets off on the quest which is also a pilgrimage as God will my guide on all souls day so all Saints is where we commemorate the canonized saints in heaven all souls is where we we commemorate the souls in purgatory right the souls that are that that died in sin and on our need of our prayers and of God's mercy so the quest is somehow connected to a purgatorial cleansing of sin then we have he wears on his shield a pentangle which is also known as the endless knot or the eternity in five wounds and I want to look at some of the significance of that so this is part 28 you see it's broken up into sections I want you to take note of the symbolism here the theology of it of the symbolism of the pentangle first thoughtless was he found in his five senses and next in his five fingers he failed at no time and firmly on the five wounds capital F capital W the five wounds of Christ for this number symbolism again which we see in the bear wolf all his faith was set that Christ received on the cross as the creed tells us and wherever the brave man into battle was come on this beyond all things was his earnest thought that ever from the five joys capital F capital J all his valor he gained that to Heaven's courteous Queen once came from her child five joys of Mary for which cause the night had incumbeny wise on the inner side of his shield her image depainted that when he cast his eyes thither his courage never fails when he holds his shield up in combat he sees a face the face of the blessed virgin staring at him the fifth five that was used as I find by this night was free giving and friendliness first before all and chastity and chivalry ever changeless and straight and piety surpassing all pie points so the five virtues here free giving so self-sacrifice friendliness so love chat chastity but I said I said shout him in chastity chivalry cause he wouldn't be a night without chivalry and piety free giving friendliness chastity chivalry and piety surpassing all points these perfect five were hasped upon him harder than an any man else now these five series in sooth were fastened on this night and each was knit with another and had no ending but were fixed at five points that failed not at all coincided in no line nor sundered either not not ending in any angle anywhere as I discover wherever the process was put in play or passed to an end in other words this endless not is eternal these virtues point to eternity therefore on his shining shield was shaped now this not royally with red jewels upon red gold set this is the pure pentangle as people of learning have taught now go away in brave array his last at last hath court he gave them all good day forever more as he thought in other words he expects this to be a fatal quest in which he will die at the end of it but you see the the the holiness with which he sets out on the quest connected the five ruins of Christ the five joys of Mary these five life giving virtues though all are signified by the endless not of eternity as he's looking for the green green night sets out on all souls day he's been wandering all over England and Wales looking for the green night he's in North Wales in a wilderness a desert and when is this during Advent alright and we sometimes forget in our modern day and age adrants a season of penitence penitential season like lent so he's passing through this season of of penance and he can't he can't find the green nights palace anywhere and he prays and he prays and he prays but his prayer is not answered on until Christmas Eve in other words the answering of a prayer of the prayer is a Christmas gift and then he sees this appearing from nowhere this castle this palace and when he arrives at the door the gate the line is yes by Peter Quoth the porter so that you're a gatekeeper who who swears by St Peter so it's a connection here with St Peter's gate there's something about entering this palace which is like entering heaven remember it's Christmas day now a time of joy penitential season over and then the Baron the the lord of the manor makes a mysterious wager with him and he's going to go out and and and give to uh he's going to go out hunting and give to Gwyn whatever he catches on his hunt uh and while his way Gwyn has to give him whatever he gets and while he's away the Baron's wife tempts him tempts him particularly to to break his vow of chastity and she's beautiful and you know and she comes into his room and so he has to use all of his powers of virtue assisted no doubt by grace to resist this beautiful temptress who tries to to tempt him to acts of unchastity but the third temptation is much more subtle so first two temptations she tries to fail she can't get him to to uh commit uh an adulterous act with her but this time she offers him a gift it's a green girdle or green kirtle you know garment if he wears it will protect him from all harm bearing in mind he's expecting at some point to meet the green knight and to have his head cut off he succumbs to this temptation this lucky talisman it will preserve his life so the third temptation is subtle it's not conceit no not the pride of the of the lady thing is she's so beautiful that uh that she can seduce the man but deceit all right she's deceiving him for it is my weed in other words my clothing that thou wearest that very woven girdle so this is that this is the uh the the uh the green knight revealing himself as actually the barren in disguise and he set uh the temptation was set by the green knight his wife was playing along uh with him um that very well go my own wife is a it awarded thee I what wed indeed now I'm aware of thy kisses and thy courteous ways and of thy wooing by my wife I work that myself I set that up it was a set up I sent her to test thee and now seems to me truly the fair knight most faultless that air foot set on earth you passed that test beautifully with great virtue great sanctity great chivalry chastity um as a pearl then white peas is prized more highly so is gawain in good faith and other gallant nights but in this you lacked sir a little and of loyalty came short but that was for no art for wickedness not for wooing either but because you loved your own life the less do I blame you all right so the how does the green knight respond to the fact that he's cheated in some way right by wearing this this green girdle this green girdle the other stern knight in the study then stood a long while in such grief and disgust he had a grew in his heart all the blood from his breast in his blush mingled and he shrank into himself with shame at his speech at that speech the first words on that field that he found then to say were cursed be ye coveting and cowardice also so cursed be coveting some things so coveting this gift because it might save his own neck literally his own neck uh and cowardice all right um it was cowardice that got him to accept this gift in you is vileness and vice that virtue destroyeth he took then the treacherous thing and untying the knot fiercely flung he the belt at the feet of the knight see there the falsifier and foul be its fate through care for thy blow cowardice brought me through care for thy blow fear of having my head chopped off cowardice brought me to consent to coveting to wanting this my true kind to forsake which is free hand and faithful word that are fitting to knights now I am faulty and false who afraid have been ever of treachery and truth breach breaking of promises the two now my curse may bear I've done both I confess sir here to you all faulty has been my fair let me gain your grace anew and after I will be where um so this this again more humility a humble acceptance of his guilt in being seduced by cowardice to covet the talisman that might save his neck um and then immediately after that we have this confession and again I have to read it because it's it's it's the it's the sacrament of confession that's been talked about here then the other man laughed and lightly answered I hold it healed beyond doubt you're forgiven the harm that I had thou has confessed the so clean and acknowledged dine errors and has the penance plain to see from the point of my blade he just nicks him just a little scratch my way of token that I hold the purged of that debt cleansed made as pure and as clean as hats thou done no ill deed since the day thou were born and I give thee sir the girdle with gold at its hems I'll give it back to you as a gift now the girdle that you talk for it is green like my gown so sir Gawain you may think of this our contest when in the throng thou walkest among the princes of high praise to will be a plain reminder of the chance of the green chapel between chivalrous nights and now you shall in this new year so what's happening it's happening on new year right at they they are renewal during the Christmas season the 12 days of Christmas that uh that he is being purged of his sin and his washed white of the snow is making a clean start coming on to my house and in our revels the rest of this rich season shall go the Lord pressed him hard to when and said my wife I know we soon shall make your friend who was your bitter foe so get to know my wife as she really is not as someone who's who's testing you and then how does it end I'm going to read this as well and then we'll wrap up this is section one oh one low lord he said at last and the lace handled and the lace handled this is the band for this for this a rebuke I bear in my neck this little scar on my neck is a rebuke for the fact that I took this to save my own skin this is the grief and disgrace I have not I have got for myself from the covetousness and cowardice that are came me there this is the token of truth breach that I had direct detected in and these must aware it while in the world I remain so he now wears it as a token of shame a token of humility a token of his own sinfulness and then further down every night of the brotherhood a Baldrick should have a band of bright green obliquely about him and this for love of that night as a livery should wear so okay all the other nights of the round table will wear it as well in solidarity why because they're all sinners right none of them are perfect so this is a token a sign of their own sinfulness that they're not perfect in this sense we can see the green girdle the green kirtle as a as a as a crucifix right that which we when we look at it reminds us of our own sinfulness our own worthiness our own need for Christ's grace and intercession and it the the the poem ends with to his bliss us bring who bore the crown of thorns on brow and otherwise make may the Christ who wore the crown of thorns for our own covetousness and cowardice and sinfulness may he bring us to his bliss may he bring us to heaven that's a marvelous profoundly catholic poem the final prayer is to a merciful God on behalf of miserable sinners and as we see how the allegory of dates is used but has been used by Dante already and will be used by Tolkien and the Lord of the Rings and on that note thank you so much for joining us in this episode of The Authority

So I want to make a video because I want to cover some details about the unified system and some of the real world problems You ran into it. So demos are always great We want to see what challenges we face when we started deploying these now the challenges aren't huge There are more annoyances, but there's actually good work for these challenges and annoyances. So When you're looking at a lot of small business and VR systems You got to think about the fact that most of the clients want it persistently viewed on let's say a TV So we mounted some TVs for these now because like the one that I'm going to be showing you right here is a smaller system with only six cameras It didn't really make a lot of sense to have two Systems in there one to view and one to record. I mean, that's nice, but you can do it on one machine They don't recommend it, but you can be done as long as the machine is fast enough to do it it doesn't have a problem because Chrome can be a little bit burdensome running because One thing that they may not tell you about these unifies is viewing a lot of cameras requires a Faster processor to do not the recording of them I showed in my other video how little processing power is taken for the recording But there's a lot of processing power because it's all HTML 5 for the viewing But there's a few things you can do to fix some of the issues you ran into So on this camera system, this is the default live view now This is actually running on the same machine that's recording and it's working fine because the machine's specced for it It's a nicer i5 with a gigs ram which is plenty for recording six cameras with a Western digital purple drive Now we've been putting in separate boot drives versus the recording drive That way it boots up really fast off an SSD then records to the four terabyte drive Small SSDs to run Windows fairly inexpensive So the next thing we ran into was they wanted it to auto launch every time it rebooted Well, there's a solution for that and I'll post this little script in here We put in this little tool called unify dot VBS and what this does is on startup launches Chrome weights Then says go ahead and press center and that's because if you notice here, we have it set to 1 2 7 0 1 780 not 7 4 4 3 now the reason for setting it to that is because that is the non SSL port that you can view the unifies on Chrome has a hard time with self-sign certificates and one of the problems we're running into when it's using the SSL is When the stream changes Chrome will time out You'll actually still be viewing the cameras But it'll give a 404 error and I see a lot of people complaining about it And this is the easy solution around it if you're viewing it locally and it's like I said 1 2 7 0 1 780 and that is the port number slash live view what the script doesn't start up is Kicks off Chrome opens up the live view page now. You can there's a push keys or send keys for Typing in the username password. It's Chrome. It's local on this computer We went ahead and did the not recommended things so to speak in terms of security But we save the password in the browser of the nvr The reality is if you have physical access to the nvr and the password you've got everything Anyways because you're in the same room But so we have the username a password saved we wait a few seconds after this gives enough time to launch We wait and then we send the enter key to go ahead and log in and it defaults right to the live view Now challenges with the live view We're gonna go ahead here at live view and we're gonna edit the view now This helps a lot and I'll tell you it's it's a big problem that we didn't expect this client is a one-to-one So they have their one computer with one TV interviewing it Maybe another TV, but as it turns out with some of our other clients We're gonna click this here to low and we'll click in this little camera icon That's on each of these low low low And low but by doing this in lowering the streams here it one reduces the burden on there We didn't change what it records that we only changed What it was actually viewing at so on the view? It's now set to a lower stream because by default that actually sends the full stream over here And then switches back and forth as needed depending on that but by keeping the stream at full It was creating some real issues Because we have a client that has nine people watching your cameras and it turned out it was a bigger burden than expected to Do that and it was really taxing the machine It's even a machine that's dedicated for recording, but by doing this Lowering the stream on the view for each person that's logging in and viewing it reduced the burden on the machine It's funny that the cameras recording Were not too hard on the machine But once you have nine people watching the same system on a gigabit connection It didn't quite saturate the connection, but it really Did a big number on the processing power it takes to send those streams back out So we weren't sure you know why the client kept having problems And this is one with a dedicated server not this particular client But what solved the problem was changing that stream to be low So they can view it now they can change it back to high if they have one particular camera And I think there's a lot of excitement when we put all the we put like 30 cameras in for the client And there was a lot of excitement to watch all the cameras all the time now each department is only watching the cameras They care about and they've edited down to views and the problem kind of went away But it was kind of unexpected I just didn't realize that everyone wanted to watch all the camera streams at once And once you burdened the system with all the cameras recording and then all the people at their individual offices all viewing the cameras It really created some errors that were really hard to trace and a lot of them were out of memory errors Because of the streaming service going in and out getting burdened so much But between the VB script and then using a non SSL internal port That kind of solved it for us in terms of the troubleshooting we had I mean we were really worried about all the problems with it But that kind of sorted it out. We did notice on the windows machines They do perform better if you do things like turn off the volume shadow copy on the Larger drive Specifically the the West digital purple drive because we're booting off an SSD And then heading over to the purple drive. We turned off volume shadow copy And it's more risky, but you can turn off windows update as well seen as these machines are Signer and that avoids them randomly rebooting or you can just run this on a server Now it the program does start up by default But there's something you have to be concerned about if you do have it on make sure you have the reboot time scheduled To be less inconvenient because when Tuesday update day comes and the computer reboots on Wednesday because it loaded some updates Sometimes clients get a little upset. So make sure you are managing or thinking about that or do like we've been doing and a Lot of them we run Linux on them And it seems to solve some of the problems because we can control the update schedule on the Linux servers a little better So that's just my short video of little problems We found in easy ways to troubleshoot it use port 7080 internally or locally if you're viewing it on the same computer Think about how many people are going to watch it at once because I don't have an exact ratio But I will tell you it certainly Was a lot of bandwidth use and a lot of memory usage more than expected one all these people started watching it once The last thing is that VBScript, which I'll just go ahead and post the in in the comments here or in the description I'll post the VBScript that we use. It's really simple No big deal there So you can Copy that in put it in startup dot VBS and it launches chrome and logs in as long as you have the password It's saved you can enhance the script You can find a few people in the forum that did a few more things like typed in a username password all with a VBScript, but we found just saving it to be fine And the multiple stream issues set them all to low for the viewing you reduce the workload on the server You release a bandwidth necessary and it also will reduce the Processing power that chrome needs because one of the couple of users which I guess it's not horrible It led to some computer upgrades for us They were trying to view it on really old computers that they had and it turns out that it doesn't render well on like You know nine-year-old computers that they probably should have replaced anyways But they were using for basic needs but watching cameras on there. You do need a faster computer I do recommend just for the viewing portion being an i5 system It actually takes more horsepower to view the cameras and it does for the system to record them So that was it. That was my quick unify update that I wanted to cover Other than that we're really liking the systems once we got those little issues sorted out Also, by the way, if you're running into the cameras being unmanaged in some of those issues it's all related to that all those problems went away by Fixing these issues it stopped all the other errors that was like cameras timing out and stuff like that Well as it runs out of memory, it does random things It doesn't necessarily tell you unless you're looking for out of memory It does random things like tell you that cameras unmanaged or that cameras decided to turn off and you thinking you're having camera problem Nope, it's all related to the nvr in a workload on it So thanks for watching like to continue like a scribe you have questions comments Let me know and hopefully this helps you solve some of the unified problems if you're ever seeing the same ones we are. Thanks


Russia withdraws warships from Sevastopol bay. Russia has withdrawn part of its warships from Sevastopol bay and Another part is being prepared for withdrawal. The Ateş Partisan movement reported this on telegram Our agent conducted reconnaissance of one of the warships parking areas located between the small bays of Dokovar and Gollandia according to our observations Some of the warships have already been withdrawn and some are being prepared for this the report said after Conducting reconnaissance around the parking area the movement reported that a checkpoint had been set up at the entrance with civilian residents not allowed to enter the territory of the facility which has been closed for military purposes Since the beginning of the war there are only warships in the parking lot Russian warships made the only right decision to leave Sevastopol We wish all troops to make the same decision otherwise they will not be able to escape the partisans said Sevastopol has been the Russian Navy's main base in the war and the home of the bulk of the Black Sea Fleet Its headquarters and its flagship while this is still the case their assets have also shifted to Novorossiysk The October 29 attack on Sevastopol in which uncrewed Surface vessels with unmanned aerial vehicles attacked Russia's Black Sea Fleet appears to have pushed them further into the shell of their naval bases Both of their admiral Grigorovitch class frigates the largest and most capable ships after the sinking of Slava class cruiser Moskva have mostly been in port one of these Black Sea flagship admiral Makarov is believed to have sustained some damage during the October attack
