In this step, then we will make a material for our corks that are currently sitting in the flasks on the table And we're going to use that as a way to introduce cylindrical mapping for UVing So we are going to go into our Hypershade first of all we'll clear the graph and we'll make a new AI standard surface Let's give it a name and one to score cork should suffice Because this is going to be another matte material We will probably choose clay because there's nothing else really close to what I want And then I'm going to load in the color So as you can see now, I'm starting to put more of my Textures into this folder and I'll just repeat again if you want access to all of the textures that I'm using you can get them using the Link in the description below the video that will give you access to my project file And then all you need to do is go into my source images folder Copy all of the textures and then paste them into your source images folder. Okay, so I'm going to go for the diffuse on the cork Lovely then let's get the roughness loaded in and that's going to be the are Lovely and then we just need the normal map and that should add the bobbly look to it. So I'm just gonna load this in again. Make sure we choose tangent space normals loading the file and cork normal Okay, and now what we want to do is assign this to our corks So you might find it a little bit easier to see if You just go back into shaded mode for this or maybe even wireframe mode and Then we're going to select both of our corks and just do shift select like that And then what I'll do is for this one I'm going to do right-click on there and assign material to selection and Now I can press six back in here and I will see my corks lovely job. Okay, let's UV map them So you can see they're not quite spot-on in the way that I would hope that they would be and I think what I'm going to do It's just work on one cork at a time. So we'll select this one first and then I'm going to go to display Hide hide unselected objects and that will just isolate this cork for me so that nothing else gets in the way So you can see the top and bottom Actually aren't bad, but going around the side not really what I'm looking for So what I want to do is just right-click on this we're going to face mode and I'm going to use marquee selection To select all of those faces going around now what I also want to do is this ring here on the bottom and This ring here I also want to select because I think they're part of the side or they look like they are to me and I could just Select them manually or I could double-click on there the loop But what I'm going to do instead is hold shift on my keyboard and press full stop Which is greater than and that will just add to the selection around my current section So that added that band there and that band there. Okay, we're now ready to UV map this So we're going to go to UV and we will click on the little options box for cylindrical You will see that there's actually not much there to choose click on project and that straight away is looking quite nice That's much closer to what I'm going for so at this stage. I can go into object mode and have a look at it So that is actually passable as it is But you can say that there's a difference in the size of the texture on the side and the top in what we call the Texel density It's a lot more dense on the sides than it is on the top Tremedy that then we're going to go into our UV editor. So I'll get it from that menu there We are going to go to UV shell mode So I'm just going to right-click in here go to UV shell each one of these pieces So we've got the top in the bottom and going around the side. These are all called UV shells I'm going to select all of them by getting a marquee selection So I've also got my UV toolkit here as well. If you can't see this don't worry You can just go to tools in your UV editor and you can click here So currently for me it will hide it or I can show it. So with these shells selected We're going to go to arrange and layout and we're going to click on the layout and What this does is keeps the Texel density Consistent so this will be our top because it's slightly bigger than our bottom and here is the side So now if I just close these windows, you should be able to see that now the size looks really consistent With that done then I'm now going to bring everything back with display show all in fact. We can do display show Last hidden which will bring back everything and that cork is done So I'm not going to repeat that process You can just rewind the video if you need to but I want you to sort your UV mapping out on your other cork and Then we can get ready to move on to the next step in that one We're going to be creating our material for the window frame and the window sill and we'll also be using an automatic UV Projection to get the UV's on that one sorted out So I will see you in the next step with sorted UV's on this cork Don't forget it. See you in the next step where we'll do a bit more materials and UVing Game Dev Academy is graciously supported by these absolute legends If you'd like to offer your support then check out our patreon page using the link in the description below


all away and stop believing in God many Christians will never ever read the whole Bible they will read bits of the Bible and hear bits in church but there will be many biblical concepts that are just simply alien to them or they will reject them and so you know following that you know many Christians still hold on to worldly points of view about politics or sin or judgment in the house of God and this doesn't in of itself make them unsafe but it's it's often a reflection of them being devoid in the Holy Spirit when you can show people things in the Bible well I don't agree with that there's something fundamentally wrong there is that they're wrestling against the words of God so as a side note then you might wonder well what about non-christians you know the atheists the Hindus the Muslims etc where do they fit in this pattern then but the thing is that there's no clear indication that they are as relevant to John 15 perhaps they're a bit more relevant in the parable of the sewer maybe if anything but this is more this is a more complicated category because some of them will never hear any biblical truth to a useful degree some of them will hear it as outsiders rather than insiders or their foreign ideas of various things will already plant anti-Christian ideas in them before they ever really know anything about Christ or what the Bible says now is there an allegorical application sure fine but ultimately Jesus is telling his closest disciples because they're going to encounter people in the ministry who seem like brethren for a season who will seem to be growing spiritually for a while but then for one reason or another will be cut off but it will take a while before this is actually manifest in the case of Judas it really wasn't until the time of his betrayal that this became manifest and so this is why the husbandman waits until a given season to check the fruit of the branch for different people this will manifest in different ways so for some Christians going through the motions of fellowship and going to church and then departing from the faith is how it is manifest to the rest of us that they did not continue for the disciples false prophets didn't always arrive to the faith false they participated in the true faith learned from the disciples gained more knowledge in the word but then at a later period it was then made known that they would preach heresy or turn against the apostles or draw disciples after themselves when they had the means of doing so for some Christians they will examine different points of view about the Bible but they may stick to one that they like the most irrespective of whether it's actually true or not some Christians will become so prideful in their own knowledge of the word or their own denominational traditions albeit in their false doctrines and the more knowledge they acquire the less inclined they are to listen to anybody who preaches a contrary view to what they believe because they just know the Bible so well many people unfortunately going to hear the word and before fruiting season they will grow in knowledge of the word but but never really be converted before cutting time essentially so if we consider the aforementioned examples of people who did not abide you know Sarah Marsden she was a branching Christ to an extent she participated in Christian fellowship she read the Bible she studied the Bible she prayed she tried to put her faith into action but upon realizing that she didn't agree with the concept of sin of judgment of salvation she realized she didn't believe and she now professes that she by her own words is much more fulfilled and thriving in life without without being a Christian so unfortunately she was never saved because Christ did not rise again as far as she was concerned if Christ didn't rise again she has believed in vain and I already answered this question you know why don't I reach out to her or try and win her over or something honestly it's because I don't have a faith strong enough to believe I could convince her because if we if somebody rejects stage one of the gospel that you are a sinner there's not really anything more I could do with that that kind of person and I think there is an aspect of well evangelism of not wasting your time just trying to bombard the same people over and over and over again you know even like the Bible says about heretics and maximum of two admonitions because there's a certain point where you keep bombarding people with stuff and they're not going to believe it and actually I had some dealing with somebody commenting on my channel the other day where he kept answering questions from a false premise and when I said that his premise was false or showed that his premise was false you just kept asking the same question as if I'd never answered it or as if his premise is already true and it there's just a point where you realize I'm wasting my time because no matter how I explain it you're either not going to get it or even even twisted what I said and changed what I actually said in his rebuttals and so if you're going to do that like I can't really engage with you and there's no point me trying to help you anymore. Again Epucee on apologetics or the ironically named Abide in the Word now he was a branching Christ when he was studying the word and questioning the doctrines that he previously believed but he was never saved because according to his testimony he measured his salvation according to his works performance and he continues to do to this day and I'm not I think now that he knows the Bible as well as he does and the amount of material that he's done and he's even said I knew that I would dedicate myself to the teaching of work you know doing works I'm not convinced that no amount of evangelism no amount of answering the scriptures that he constantly straw man's is ever going to get him saved he has had rebuke from multiple free grace believers he tried asking questions like he did his silly Hebrews 5 9 challenge or something and plenty of people answered him but all he did in response he just straw man the people who tried to answer him he made false claims about what free grace actually believes he is given over to his another gospel his another Jesus the real Jesus said no man shall ever pluck them out of his hand he has to find excuses and exemptions by going to non salvific passages and so that you know I mean he's welcome to prove me wrong if he wants to get saved he is welcome to prove me wrong at any time and I will make a public apology but until that happens I'm not convinced he's ever going to be saved he's given over to this he he's been cut off as far as I'm concerned and of course we have biblical examples you know Judas Iscariot was with Christ for several years he was surrounded by Jesus closest and most zealous disciples he heard Christ's teachings firsthand I mean that's a privilege more than most other other men that have ever lived on the planet okay he had that amazing privilege not only did he remain in unbelief he willingly stayed for the purpose of being a traitor the disciples in John 6 were branches in Christ for a season while they dedicated themselves to his teaching and followed him as he did his ministry and he gave them his teaching but they didn't really believe as the 11 did it just wasn't known in the sight of man until the events of John 6 when they were finally choked on his teaching that that they would not continue but Jesus already foresaw this and when a branch is cut off it's it's withered it's burned and so this would suggest that there is virtually no hope for it after that point and this is perhaps why Hebrews 6 says if they are enlightened if they are tasted but then fall away it is impossible to renew them onto repentance okay and don't misunderstand this as being an age thing you know that a Christian who's been unsafe for 20 years is unsalvageable sometimes you know for some people it just takes a lot longer than other people for fruit to grow and to to be made known but you know think about this though when was the last time a very well-known theologian or church minister or evangelist I'm talking about really well-known people like famous people you know you're John McArthur's of this world you're John Piper's and that can you ever imagine a well-known lordship teacher or something converting in the final hours of their life right can you ever imagine a conditional security street screamer like Jesse Morel or Abide in the Word ever changing their position and getting saved you can't really it's you know when was the last time that ever happened it's super rare that that ever happens and it's very unlikely that Sarah Martin will at this point ever become a Christian again because studying the Bible actually led her to rejecting the faith not accepting it and she is now it by her own words much more fulfilled in her non-Christian life and so really the Bible just has nothing to offer for her really now this I know this sounds like I'm ending our study on a negative when I've been so adamant before that this passage is supposed to be an encouragement so you know perhaps you are wondering you know now I'm worried that what if I don't abide in Christ what if I end up being cut off well the thing is if you're asking this question I think it's kind of fair to say that you're not cut off you know it's kind of like the people ask what if I've blasphemed the spirit well if you blaspheme the spirit you wouldn't be asking if you blaspheme the spirit probably you've listened this far into the study which means you're at least willing to listen you're willing to hear these you know arguments presented from the Bible now whether you would end up agreeing with them or not is between you and God I can't help you with that but you know if you love Christ and you believe him in what he said you are a branch that is growing and the goal of this salvation series is to help you grow so that in time if you're not fully confident in Christ you will reach that point you will bring forth fruit to the saving of your soul that hopefully one day you will get other people saved you know Christ spoke to his closest disciples and he did not leave them comfortless he solidified their faith when he rose again and we can know in hindsight that he defeated death and all you have to do is believe on him and trust what when he says that I am the father in the father in me and I should lose nothing you just have to believe him when he says it that's all he's asking you to do really and so yes those of us who are saved we mourn when we see people who don't abide and fall away and it you know it breaks our heart inside but unfortunately that that is something that's between them and God they've heard the word of truth they've rejected it so you know don't let that be you and God already foreknows those who would be saved he's already predestined them and chosen them and so yes there will be many who fall away but there will be many who don't too and regarding the branches who bear fruit God will receive his first fruits as he gathers his people onto himself and if you've been following my John series up to now John has set us up for everything we need to abide he has given us Christ words in the stories and the dialogues he recorded you know he recorded cry saying believe on me have everlasting life this is a simple instruction there is nothing complicated about this whatsoever he recorded in his gospel cry saying unto us I give unto them eternal life and I should lose nothing and I will in no wise cast out so believe him when he says it and stop making excuses as to why might lose you or you might walk away just stop adding exceptions to the words that Christ gave stop trying to cancel out Christ words about eternal life using passages that aren't talking about the subject so don't negate salvation passages with non-salvation passages with these books and what aboutaries okay and so I'm going to conclude our study there because this study has been exceptionally long and you know cooled us to those of you that have listened this far in it's been very mentally exhausting putting this material together because it's just such a difficult chapter and we've barely unpacked half of it I've not even finished the latter half of the chapter it's just such a complicated chapter and you know people might disagree with some of the stuff that I've said about this which is fine because again it's so cryptic in a way so we haven't covered the latter half of this chapter what I'm going to do is though there is more that I could have said about that in the middle of it but I'm going to join that with chapter 16 so when I do a study on John chapter 16 I'll just do the latter half of 15 as well because really that that part of the conversation really more belongs to John 16 anyway you know I wouldn't quite re I wouldn't quite change the chapter number where the whoever made that decision did so that's just one of those things but if you think there's something that I've missed please do let me know in the comments this is such a complex chapter so you know a bit of iron sharpening iron would help me too I'm not sure how long it would take but you know stay tuned for the latter half of chapter 15 and 16 hopefully in a few weeks you know very soon but I might have to put it on the back burner for a while because I want to start getting material done for a second documentary so you know I'd like to prioritise that leading up to Christmas and I'm just a bit busy with work at the moment as well


Cultural Heritage Preservation has been revolutionized by three-dimensional 3D scanning and 3D printing. These technologies allow for the creation of detailed digital models of cultural heritage sites, artifacts, and monuments, as well as the production of physical replicas. This has enabled the documentation and preservation of cultural heritage in a non-invasive way, while providing educational and exhibition opportunities. However, there are still challenges associated with this technology, such as the need for specialized equipment and expertise, as well as concerns regarding the preservation of the original objects. Despite these challenges, 3D scanning and 3D printing have proven to be valuable tools in the field of cultural heritage preservation, and their use is expected to continue to grow in the future.

Hi guys. Now I saw somewhere that you could use a couple of diodes and a resistor in this interface of a radio. I didn't believe it and I tried just having this one little piece of you know like hookup cable as an antenna but it didn't work very well. This is just my crystal radio. I'm actually going to hear it. That's because I've connected it up to the input on this little common wall. This is TDA something. TDA 7267. The old mono amp. I don't know if you can hear it that well. I can hear it from here. But that's the radio.


Despite how booming this year has been for game releases, there has still been quite a few games that have been released, and I didn't talk about them for one reason or another, like Just Dance 2022. The reason? Well, it's Just Dance. The thing is, when I don't have a lot to say about one game, it makes it kind of hard to create a full video that will peas the YouTube algorithm, or so I might not have that much nice to say about a game, and if there's one thing my dear old grandmother taught me, it was that if you have nothing nice to say, don't say anything at all, unless it's about Just Dance. Hey, you okay? I'm sensing something strange. Yeah, life is strange. Yeah, it sure is, buddy. No, the game, Life is Strange True Colors, the Nintendo Switch version launched today. I hope the Life is Strange games are great.  The best part is, it's the same game as it is on all the other platforms, including all the character performance capture and facial animations, plus the full extensive licensed music soundtrack. Yeah, the Life is Strange games are known for their beautiful music and fantastic storytelling. Yeah, I'm glad it's exactly the same on Switch. It's not just the same. They had a dedicated and passionate team create this port specifically for the Switch. They rebuilt the lighting engine ground up for the console. They completely reworked how the CPU processes and renders scenes to optimize frame rates. Heck, they reworked almost everything from the character models to the game's foliage and anti-aliasing to preserve vitality while optimizing polycounts. How to be honest, all this sounds incredible. I don't understand why- It even plays at 1080p! Stop! This is not Switch! Switch! Switch! Switch! Switch! Switch! Switch! Switch! Switch! Switch! Switch! Switch! Switch! Switch! Switch! Switch! Switch! Switch! Switch! Switch! Video is brought to you by Life is Strange True Colors. If you've never played a Life is Strange game before, True Colors is a great place to start, as it's a brand-new and exciting story filled with twists and turns, six different endings, supernatural powers, and just a ton of heart. It's a very inclusive game that can be played by both casual and avid gamers. And it would be a great gift idea for this holiday season. A physical edition will be launching in February of 2022, but the digital version is available right now on the eShop. So click the link below to check out the game and support my channel. I do want to cover as many Nintendo Switch games as possible on this channel, while I have some sort of relevancy on the internet. And Metroid Dread has always... Wait, where did I put that game? Does anyone know which way I'm supposed to go? It was here the whole time? Metroid Dread is a game that was 15 years in the making. It was conceived back around 2005 as a sequel to Metroid Fusion for the Nintendo DS. However, the technology back then was too limited to create the game that Yoshio envisioned, so instead he decided to wait until Nintendo developed a console powerful enough to handle his 2D side scroller, and that only took almost two decades. Thankfully, the wait was worth it, as Metroid Dread instantly became one of the best titles on the platform as soon as it was released. The only reason I never talked about Dread is because the day it came out, I was catching a flight to Philly for too many games. A convention that was a whole weekend long, and in 2021, that's about how long it takes the internet to forget about something and move on. And by the time I landed back in Texas on Monday morning, everyone was already back to asking where Metroid Prime 4 was. Bummer for me, because I actually managed to finish the game on both flights. I finally did the whole Nintendo Switch thing of getting on a flight and propping the OLED screen on the chair in front of me and then holding both of my new white joy-cons in either hand. Dread takes approximately seven to eight hours to finish, and I had two four-hour flights, so basic math would tell you that I actually enjoyed flying for once. I loved every second of this game. The controls are super tight, and the action is non-stop, fast-paced, blood-thumping, jump over this duck under that black, black head, yeah! And it only picks up the pace, getting more intense and more difficult as you progress and unlock new abilities and power-ups. I'm sure like 99% of people already know this, but the Metroid series was so influential in its time that it spawned its own genre of video games, Metroidvania. Well, Metroid and Castlevania, but that's a tangent for a different time. But thanks to Metroid, now we have games like Ori, Steam World Dig 2, and of course everyone's favorite, Hollow Knight, so it's tough for a game like Metroid Dread to release all these years later in the very same genre it defined, but also compete with the newer experiences. But Dread does it seamlessly, with some of the greatest level design and progression in the genre to date! Yeah, it has really good game design. Dread carries over the counter system, from Samus Returns, allowing you to deflect and then attack enemies if you have perfect timing, made even more intense during the Emmy encounters. So the Emmys are these machines that were created with the strongest material in the universe. Think like Valerian Steel in Game of Thrones. This is Valerian Steel. So all those really annoying plastic ties they put in new clothes to hold the tags on that you can never rip apart with your bare hands and then they start to cut and bleed. Sorry. Seven Emmys were sent to the planet to investigate but they all went missing. They became corrupted and now their prime directive is to murder Samus dead. And nothing in Samus's arsenal is strong enough to take them down. So when you find an area that an Emmy is living in, the tone of the game completely shifts and it becomes a real terrifying threat. You do not want to spend any time in these areas and despite how creature-infested and hazardous the rest of the game is, in comparison to the Emmy zones, the rest of the game feels like a day trip to Chuck E Cheese. So you'll either want to blast through Emmy zones as quickly as possible or stealth through using any abilities you have. If you do get pinned down by an Emily, you can use the counter as a last chance resort of temporarily stunning it.  The boss fights are the highlights. Not even just for the gameplay but because here is where Samus really gets to show off her badass self. Some of these cutscenes and action moments really allow our favorite space warriors personality to shine through. Oh, and no spoilers, but that last boss fight is one of the toughest fights I've ever had to rage my way through. And finally, the visuals are gorgeous. In both handheld and docked, Metroid Dread is crystal clear with these huge environments that reach back seemingly miles into the screen. Even the tighter spaceship and cave-like environments are highly detailed. All lit by the wonderful dynamic lighting. And all the alien creatures are fantastically designed and animated from the giant monsters to the tiny bat things with waggly tails. Metroid Dread is a near perfect experience and both myself and RGT are really hoping it passes three million in sales. Shin Megami Tensei 5? Did I, was I close? Shin Megami Tensei, Tensei? SMT-5 is gonna be a little tougher for me to review as not only have I not finished the game, but I've barely even played it. I just, I don't think it's for me. I don't think you're for me. I'll start by saying I loved the setup. Typically in these types of games, you spend a while during the start getting to know the characters, going to school, learning about the world before everything goes to hell in a handbasket.  After just one quick exam that I can only assume I nailed because immediately after everything gets turned upside down and you find yourself in a vast desert filled with devils, angels, grimers and cats. Shin Megami plays out a little like Pokemon where not only can you battle the demons you discover, but you're also encouraged to sit down and have a conversation with them, maybe share a cup of joe and talk about the daily going on. The weather's been nice lately. Did you watch the Knicks? So what sport people say? Did you watch? I kinda like these strange conversations. It's like talking to old people in a retirement home. Every demon is completely different in the way they talk, what nonsense things they want to talk about and what kinda answers they want from you. Some will prefer you to be submissive while others might prefer a strong leader or some might straight up just want your money. Sounds like my wife. What did you say? Nothing, honey. Amass your demonic horde, level up and progress through the game, or I guess that's what you're supposed to do. Look, I'm never the first person to say a game is too hard. I love a challenge, but this is easily one of the hardest JRPGs I have ever played. Unless I'm doing something completely wrong, which is very easily a possibility.  Just a couple hours into the game and exploring the world, I came across this story boss, a massive hydro, which while looking incredibly cool, kept one hitting my entire team. So I found myself two hours into this adventure having to go away and grind. I tried grinding levels for about 30 minutes as that's what felt appropriate for this stage of the game. I came back and just like my butt after Taco Bell, I was wiped again. That was an awful joke. So off I go for another hour to squeeze out what levels I could, but the random enemies around the world stopped giving me any kind of sizeable XP boost to notice a difference and even though King Hydra over here was less able to one-hit me, especially once I learned that I was supposed to be guarding against his big attack.  I still couldn't put a dent in his massive HP bar while it whittled down my entire team to nothing. So four hours into the game and I started to feel like half the time I had been playing SMT5, I had made no progress. Now I love a good grind as much as the next guy, but for me hitting a grind 20 to 30 hours into a JRPG when I'm already invested in the story and the characters and I have multiple abilities to mix things up with to keep the grind as fresh as a good cup of coffee. Now that can be fun, but two hours in when I just had a couple of attacks at best just felt punishing. I almost shelved the game completely until I had a thought. Not a good one. I thought I legitimately have never had before while playing a game. I wonder if I can lower the difficulty. I mean this when I say I've never put a game on easy in my entire life. I always play games on normal because the way I see it, that's the way the game is designed to be played normally. And I mean, sure, I've put a game on hard before for an extra challenge, but I've never put a game on little baby way be easy.  But I gotta be honest, it felt bad. Didn't, I felt cheap. I felt like, felt like I was walking out of a $2 motel after doing something questionable. I felt dirty. It felt like I didn't deserve to progress. I was conflicted in my emotions. I felt disconnected with the experience and I was no longer invested in the game.  But I think one day soon I do wanna try again. I wanna start the game completely fresh, maybe even do it on stream. So y'all can yell at me and tell me what I'm doing wrong. So this isn't my review of SMT5. This is just my experience playing SMT5. And I think it, for true JRPG fans and those that love a challenge, you need these brutally difficult games. I mean, maybe this is like the dark souls of the JRPG genre. And in that regard, I'm sure this is a banger. But for now, I'm gonna stick to my paper Mario's. I'll go say baby way be easy and one launches soon on 64 online. Speaking of games, I've been playing on Twitch. The main reason I haven't talked about Pokemon Special Diamond and Pretty Pearl is that I'm not done with my playthrough yet. Let's get two things out of the way really quickly. One, I have found a way to make this game fun again. And two, yes, I think the game is hideous. This is a very diverse topic. And I don't wanna get too into it. So let's get right into it. Art is subjective. So you can love it, you can hate it and both answers are okay. I don't wanna see anyone fighting in the comments, especially towards me. And yes, I am making full use of there being no dislike button anymore. Okay, maybe hate is coming on a bit strong. But I find the art style extremely ugly. And I wanna say Borderline Amateur, which would be fine if this wasn't a Pokemon game. Literally the world's largest franchise and presumably a company with lots of monies. Many people are quick to point out this game wasn't developed by Game Freak. Rather, this remake was handled by Ilka, which is true. But defending an art style by saying Game Freak didn't do it, someone else did. Doesn't really fly with me. When they can afford to have literally any studio make it. But instead, they chose a studio who doesn't even have a Wikipedia page yet. So it made things a little tough for me to even find out what other games they have made in the past. But from all I could find, they have made by themselves is the Pokemon Home app. So it's completely fair and safe to say that these Pokemon titles were Elka's first ever games. And again, I'm fine for that. Happy for them even. And as far as a one for one remake, they did an incredible job at accurately recreating the games, especially for their first attempt at making games. But visually it's just nothing special. And since the visuals are the only reason to play this over playing the original, it just strikes me as weird that Game Freak didn't reach out to a company that had a little more experience in creating visuals in a game or at least give Elka access to the same engine and assets they created for the Let's Go games. This is a long tangent on something that really doesn't matter. And ultimately it's just my opinion. But it's just that perfect pearl and dazzling diamond were two of my favorite Pokemon games. And I just don't feel like the remakes did their beauty any justice. The level of care and detail that was given to the Let's Go games were missing. And a perfect example of that can be seen in just booting up the games and comparing the initial title screens.  And the other looks like it was mocked up in Microsoft Word and they accidentally forgot to change the color of the lower text from red. And I know this is a small thing to nitpick but it does resemble the rest of the game in my opinion. Look, I know I've compared this game a lot to Let's Go and granted for the most part they are two completely different styles. If you prefer the squatty Chibi look that's fine but the Chibi style is still missing the lighting effects, shadows, the animations look cheaper and ultimately it just needs a ton more polish to make it. That's the last time I'm gonna talk about it. It's tough to avoid talking about it as again the only difference in remaking this game, a one for one remake is the visuals. So in a way it's really the only thing I can talk about that's different without just reviewing the game as it's always been for years. So as far as the game goes, yeah it's a one for one remake. It's the great games you remember. And I have been a little a lot burned out on the traditional style of Pokemon. So this time I decided to try something different and it has completely changed the game for me literally and emotionally. Have you ever heard of a little thing called Nuzlocke? Yeah, I know I'm like probably 10 years too late to this. I decided to try my first ever Nuzlocke challenge something I had never even cared to learn about before I had a pure desperation to change up the formula of these older games. So here's how it works. Once per new route you are allowed to catch the first Pokemon you find in the wild. If you accidentally faint it or miss it you can't catch another Pokemon on that route.  Other rules are you can't catch duplicates. So if you already have the first wild Pokemon you find on the route you can look for another one. You have to nickname each Pokemon too. And furthermore if a Pokemon faint at any point it's treated as being dead and you need to release it back to the wild of which it once came.  It's a fresh way of playing the game that keeps you connected and attached to each of your Pokemon. You have a much smaller pool to choose from and it forces you to use Pokemon you normally never would and let me tell you every lost hurts. I've been turning my Nuzlocke streams into fully edited videos on my highlights channel so you can go and watch how deeply my soul leaves my body every time I lose someone. Especially my starter. I have never ever felt so emotionally attached to my Pokemon before. You would think that playing these games would be a breeze especially with how many quality of life changes they've added to make the games easier these days like constant EXP share but I'm telling you it just takes one awkward Pokemon matchup at a gym to ruin your entire playthrough. Oh! Despite how I feel about the game's visuals it doesn't matter like I said because this is easily the most fun and the most stress I have had playing a Pokemon game for years. Okay, I hope you enjoyed this video. Clearly I loved Dredd and then had mixed feelings on the other two but again that's why I didn't make them their own videos and I can't adore every game the way it's supposed to be adored. Sometimes you just don't like something and I can't help that but I still wanna talk about it and now the dislike button is gone. I can't. Do like the video, subscribe and comment but also the highlights channel where I'm uploading the Pokemon Nuzlocs go give that a sub because a lot of my streams from Twitch I'm gonna be editing from now on and uploading them there as well as little short videos which I'm also doing on TikTok now. I know it's a lot but I have a TikTok now and I'm uploading original content to TikTok things that I'm not I'm not just cutting down YouTube videos I'm actually creating TikTok content. Oh, those words made me feel old. Finally those Twitch streams that I'm editing they happen on Twitch and if you wanna watch them live we have a ton of fun over there so go follow me on Twitch and watch Twitch as well. All right everyone that's my whole thing. Bye bye.


From San Francisco, it's theCUBE, covering PagerDuty Summit 2019. Brought to you by PagerDuty. Hey, welcome back, everybody. Jeff Rick here with theCUBE. We're at PagerDuty Summit in downtown San Francisco. It's about 1,000 people, fourth year of the show, third year of theCUBE is here. Happy to be back. Ironically, a couple of weeks ago, we were at SimaLogic, Illuminate down the road by the airport, and we're excited to have somebody from Sima here talk about how these platforms work together. So, returning, again, is Jonathan Rennie, SVP of products at PagerDuty, and joining us is Bruno Kurtick. He's the founding VP of Product Strategy for SimaLogic. Bruno, great to see you. Jonathan, welcome back. Thanks for having us. All right, so, Bruno, we're just at your show, now you got to take it a little bit easier, probably not quite as many responsibilities. We'll talk a little bit about the relationship between the two companies, because from the outside looking in, it looks like there's some redundancies, it looks like two platforms, it looks like where's my single pane of glass, but in fact, there's a real synergistic opportunity to work together. A good question. So, there are two platforms, but it's entirely synergistic. You know, between the two technologies, PagerDuty and SimaLogic, we sort of help our customers who run mission critical products and services that serve their customers, in fact. Number one, get information from their systems and applications to understand what's happening in them, and then leverage our two platforms to resolve those issues, make sure those applications are running, that their customers are happy, that they're delivering the services that they are there to live with them. And I know, Jon, you got a long list of great companies that you guys worked for, and you said it's a really key part of the company strategy. Yeah, the ecosystem that we work with, one of our favorite partners, SimaLogic, we use Sima, we're a big customer of SimaLogic, as well. And it's really important, all of the telemetry, all the machine information that's coming in, again, the part that we play in that is, how do we orchestrate people to get work done when things go south? Right. And how do we get the right people on and give them some information about what they're doing to help triage what they're doing? Right. So, the two work together really, really well. So, one of the themes at both keynotes, it remains keynotes, as well as Jennifer's data, and the fact that you guys both have a giant proprietary data set of both machine activity and people activity from running these businesses, I've teased it on Twitter and overnight sensation, 10 years in the making, that you can leverage to deliver more value. So, as we look forward, data's been important, but now, all the hot topic is machine learning and artificial intelligence. How are you now taking this kind of next gen technology and applying it to these giant data sets to offer kind of proprietary insight to your customers? I'll start with you, Bruno. Sure. So, there's a massive amount of data, right? And it's growing at the rate of Moore's Law. So, there's more data that any human can cooperate. And so, our task at Sumo is in figuring out what is that data trying to communicate to you? So, we spent a lot of effort on machine learning, pattern detection, advanced analytics to help our customers short through that massive amount of data to understand whether their services are available, whether they're performing, whether they're secure, whether they're compliant. And we boiled that up into a set of insights that we then feed downstream or upstream, in this case, to Pedro duty, to help those people who are responsible for those services do the work to make sure they're restored and working well. And I guess to compliment what Bruno's saying, one of the things that we're doing is we're also ingesting a lot of data, a lot of machine data from monitoring products and from service desk products, other kind of sources of data, because that also informs who needs to get engaged when a system goes down. And then what do they need to do in order to fix it? And so, it's all context, it's all data, and how we can help narrow that down. We had a really interesting statistic, this was earlier this year, where we were looking at per responder how is this growth of interruptions, kind of alerts, how is that trending? And now, compared to just a couple of years ago, it's about three times the amount of noise that's coming at them now per responder than three years ago. So clearly, the people on the end of this are getting overwhelmed if we don't do something intelligently to make sense of it for them. Right, that's interesting, because it's really a lot, I don't know, false positives, I don't know if that's the right characterization, but certainly too much to prioritize and an overwhelming amount of data for a person to try to filter. So you're really trying to add that intelligence on the front end, so hopefully the right problems are getting surfaced and not just as broad base of false positives or minor positives. Yeah, it's funny you say false positives, because one of the concepts that we have is there are alerts and incidents that need to be managed, but then there are unactionable alerts and incidents, things that really shouldn't be bothering you. So you have to walk that fine line between what do you act on that you should take action on and what are the things that you shouldn't take action on and kind of ignore. And so we use machine learning to do a lot of that work and filter out the bad noise and bring the important information in. Yeah, I wonder if you have any thoughts, Bruno, on how much of that filtration needs to happen to kind of quiet down this tsunami that's coming over the transom? Well, in our terms, it's, you know, every one of our customer centers billions of records per day, literally billions. Billions of records per day. Billions of records and sort of figuring out what matters amongst those billions of records is a hard job. There's a lot of false positives, false negatives that need to be sorted through before it even gets handed up to the upstream technologies like page review, right? So we spend a lot of time doing outlier detection, doing predictive analytics, doing sort of pattern detection, machine learning type of techniques to make sure that the stuff that gets bubbled up has as few false positives and as few false negatives as possible so that the insights that are intelligent, the actions that need to be taken are most appropriate and can be prioritized and handled by a small team of people who own those actions. Right. It's funny to say billions and billions. I have a visualization challenge. I keep throwing out to people and I've yet to get a great response which has shown me a billion piece data set in a visualization that I as a person can look at and comprehend what the heck is going on. Beyond something as simple as, you know, half of them are on this side, half of them are on this side. I mean, we're not wired for that way. We're not wired to be able to take in billions of data points. It's just not going to happen. Just for that context, we actually, we analyze a quadrillion records a day. So, talk about billions and then, you know, many more orders of magnitude than that. It's, those are numbers that are hard to comprehend, right? We don't think in those numbers, right? It's really hard for humans to gross up. So, how do we keep up? I mean, how do we keep up? I mean, it's kind of a bigger problem but you know, as much as anybody, kind of the exponential growth of this data, we're barely getting into IoT and industrial IoT and sensors on everything at the house and on our clothes and our shoes. You scared about keeping up? Can we keep up?  We have to kind of gait it somehow? So, from my perspective, there is no sense in being scared of it, right? A digital business generates data without that data that can't run. So, the task is to capture it, analyze it, to understand it and serve up intelligence from it, right? So, our task is to keep pace with that growth and build resilient, scalable systems with the analytics that are required to understand it, right? And so, you know, we can't shy away from it so whether we like it or not, it's not an easy task but we can walk away. Right, right. And then the other just crazy, increasing complexity. No, thank you. On your guy's side really is the variety. I mean, we used to talk about the variety, the old big data, the big three, you know, variety and veracity and velocity. You know, the interconnectivity of all these systems is also the thing that's growing so exponentially and so when something does break, the ability to find what broke amongst this huge potential is really a hard and growing problem. Yeah, it is and that's why sitting in the middle of an ecosystem of a lot of different products that we'll give and send off telemetry that we have to look at is really important. It's almost as if like the information that we're always looking for in the PagerDuty platform, it has to be items that really are actionable by a person which, you know, if you look at the information that is flowing into Sumo Logic, it's even in some ways very broad and so it's a wider funnel. We have a narrower funnel kind of information but they're both very complimentary of each other because one is that humans need to act on in the moments and the other is how do I analyze in a broader sense, even a bigger range of information. So both are so critical as a part of that whole ecosystem as I was saying, we personally use Sumo Logic as a big part of how do we actually triage actual incidents. We built tons of libraries in the Sumo Logic product so we can make sense of even a broader set of information flowing in from all of our logs in some of those critical moments. So it's, yeah, it's great Sumo. Good, good. Well, I'm glad you guys are working on this big data problem because it's a big, hairy one. And the customer's only benefit, right? Yeah. Well, Bruno, Jonathan, thanks again for taking a few minutes. Congratulations on the collaboration. It looks like it's working pretty well. Good guys. He's Bruno, he's Jonathan. I'm Jeff and you're watching theCUBE. We're at PagerDuty Summit downtown San Francisco. Thanks for watching. We'll see you next time.


First of all, it's a great honor for me to be at this conference, so for once I decided to act more responsibly and I've somewhat reduced the scope of this talk, so we might not actually get to what I call fundamental local equivalence. Basically, let me just say in words, the story is like this. So the fundamental local equivalence is a basic local ingredient one needs to formulate quantum languines, but that happens on the Durham side of Riemann-Hilbert and basically due to time constraints I decided to stay in this talk completely on the Betty side of Riemann-Hilbert. So there is an extra story going on maybe on some other occasion. All right, so let me begin. So let me remind you the usual geometric satake. So let's say we start with a curve x and a point and the story will be completely local around this point and just to introduce a notation. So I consider the group scheme geofo x is the group of arcs and the group of loops geofkx and one considers the affine-grasmanian which is the quotient. So let's say everything is taking place over some algebraically closed field. All right, so in the usual geometric satake one considers the following category. So one considers perverse sheaves on the affine-grasmanian that are equivariant with respect to geofo x. It's a geometric analog of the of the spherical Hecker algebra in the theory of Piatty groups. So this category has a natural monoidal structure so in the basic theorem which is known as geometric satake reads that this well as a monoidal category it's equivalent to the category of representations of the Langlund's dual group. All right, so yeah, so I'll say that in a moment.  I just want to make sure which order I'm saying them. I pretty forgot the first one. What's the first comment? Yeah, so first of all well as we can see this category is not just monoidal it's actually symmetric monoidal category. What one can do well in the process of the proof of this theorem one promotes the monoidal structure here to a braided monoidal structure when introduced commutativity constraint that turns out to be symmetric. Okay, now what context is the same? So what do we mean by proper sheaves? I'll comment that on that in a second. So basically this is true in any of the familiar context so one can do a ladic sheaves working over an arbitrary ground field. So in this case this is a ql linear category and we understand g-check as an algebraic group over ql. So it does. So it's also true with fl coefficients or zl coefficients. So let me say all right so another context is one can do so if the ground field is is a characteristic zero one can do d-modules. So in this case if we call the ground field k this is a k linear category and this is also an algebraic group over the same field k or one can work over the ground field being complex numbers and one can consider sheaves in the classical topology and in this case one can take as coefficients in fact any ring any commutative ring. So but for the purpose of this talk we'll take field coefficients so over c. So this is also the is there any finalist condition like traversives are constructively usually and so you maybe want to have taken a part adjust the face of the because it's a union of a variety you want to take a fairly many cells and with both constructivity and the representation also with the old finite generative module over your ground ring so if the ring is not good then you have to know what to say. Yes so let's let's be safe here so for this formulation let's let's take field coefficients just just to be on the safe side so in this case I'll take really constructible perver sheets so they live on finite they're supported on finite dimensional pieces and here I'll take I'll just take finite dimensional representations. Yeah so this theorem is due to many people so kind of if the initial input came from Leustig then I believe it was conjectured by Drinfeld and then it was proved by Ginsberg with coefficients in characteristic zero and Mirkovich Villanin with coefficients in arbitrary ring. All right and okay all right so now so this talk is about generalizing rather deforming this equivalence so this equivalence as stated has the following drawbacks so first of all it does not extend to the derived level so namely instead of perver sheets let's consider the the derived category so my notation for the derived category I don't like to write D I like I write sheaves so and when I when I write sheaves I mean the derived category so I consider the equivalent derived category in the affine-grasmanian but then which part of this condition in a second it is important to allow infinity sometimes yes and I will say that in a moment so we will be in allowing infinite infinite things so let me say okay so at some point I'll have to adopt this convention and I may as well do it now I put no finite I put no finiteness conditions just it's the un unbounded derived category I know but you see if you want any influencing to be a direct limit of things supported on the product of constructiveness like for usual so you have the sheaves which are supported on that on the union of part of closures the fighting when orbit so this but you can never see if like the constant shape for your technique constant shape see on on the graspania is it a ship in your sense we'll I'll address this point in exactly five minutes I'll I will I will talk about this in great detail in just a few minutes yeah so yeah just um yeah we'll I'll introduce what I mean in a moment just notationally so because this is my notation for the derived category whenever I talk about a billion category I'll put a little heart so here this wasn't well it's the heart of the t structure so in this notation this meant an equivalence of a billion categories and so without the heart it would mean the derived category and one may want to compare the equivalent derived category in the fine grass manian with the derived category rev the check and even if your coefficients are characteristic zero these are not at all equivalent so you can explicitly say what this thing is and it's not that it's something else so so that is to say that this is it's a kind of fragile statement it only take it only happens at the at the abelian level so another point is and again this is kind of the main direction of the stock is that as we will see in about half an hour that um so the right hand side admits a quantum deformation so namely there is such a thing as representations of the quantum group and you may try to deform the left hand side but again this equivalence even at the abelian level will completely fail so and so the first thing that I'll do I'll replace this equivalence before any quantum deformation by another one that is better what not want to qualify things by an equivalence that will hold at the derived level and one that will admit a quantum deformation all right so okay specifically to address offers question let me say what I mean by the category of sheaves so we take as an input this the theory of sheaves on algebraic varieties of a finite type so if y is an algebraic variety finite type to it we assign something that called sheaves of y and so basically for now the only functor reality that we need is the following that if you have y1 mapping 2 by 2 what I need is well shriek pullback functor so up a shriek yeah yes so for the particular story that I'll talk about one can make do with without higher categories but it's again it's very fragile so better right away proceed this as as the corresponding high categorical enhancement of the derived category and now so now we are in the in the finite dimensionation and let me say here that I should technically specify what I mean so what I mean is the following in the world of demodules I take the entire unbounded category of of demodules so no finiteness conditions so in the world of constructible sheaves what I do this again it's a technical remark so feel free to ignore it I take the usual constructible category and I'll pass to what's called the incompletion is it just for ships or the derived category the derived category so I have them again in the constructible world I have the higher category well higher categorical enhancement of the constructible derived category of the bounded constructible category the kind of the usual one and then I take it what's called the ind completion is it different from the unbounded unconstructible it is different yes it is different but only was like was was trolling coefficients it's the same right yes but I yes you want ql coefficients so in with let's say if I work with ql coefficients yes I do the following thing I take the constructible category and take its incompletion but in the topological world I'll do the same I'll start with a constructible category as it is yes and then I'll take it in completion so usually you consider complexes with only constructible commodity yes this is what you do yes and for d models you take complexes with with quasi-coherent common no if the demolish I can do either of the following two things for d models what I can do I can do straight away I can take the unbounded derived category with no coherence conditions or or quasi-coherent oh of course quasi-coherence but what they said quasi-coherent the all module homology yes quasi-coherent yeah quasi-coherent yes but the object itself don't have to be quasi-coherent this is the point maybe many cases you can do it yeah all right so so now let me specify what I mean by sheaves on something like the fine grass manian so the fine grass manian can be written as a union of an increasing family well of close of schemes each of which is scheme of finite type let me say so it's an ordered set and if you have this then have this closed embedding and so the derived cat so the category of sheaves on the fine grass manian is by definition well I should write it like this it's the so in other words you should think of an object of the category sheaves on the on the fine grass manian as a compatible family of objects on each of these y alphas and compatible in the sense of shriek pullbacks the shriek pullback to each other so that's the definition again well there are time constraints otherwise I would be able to explain why this is exactly what you want okay so this is okay so let me let me so okay let me make let me add this comment okay okay it's a it's a general useful observation but it's very useful so let me say it like this suppose you have a family of categories indexed by some set so as c alpha c beta and there are functions and let me symbolically denote these functions by l like this and suppose it so happens that these functions actually admit left adjoints and I'll denote them which is exactly what is happening in this case because these are closed embeddings so in this case there is a general lemmon which I learned from luri and it says the following that the limit of the inverse family under these functions is canonical equivalent to the co-limit of the direct family one there's a tiny remark one has to add here namely do you assume that the raw shrink guys are fully transformed? no it's it's completely general so therefore you can think of this resultant category in well either as compatible family under shriek pullbacks or you can think of objects there as coming well if you wish as co-limits of objects that come from individuals individuals c alphas through the low yeah through the push forwards and so and this is like what I said this is like what you said before and this is an explanation why this is exactly what you want you want to think of the sheaves on the entire thing as constructed from sheaves on finite dimensional pieces so this presentation gives that point of view it this happens it doesn't matter for the it doesn't matter for this claim but in this case it happens to be filtered okay so here you are you may work with usual categories and then the usual two limits and two co-limits in the two categories they may also work in your higher setup no so this is this happens in the higher in the higher world not in the does it happen in the world of usual you mean you mean usually meaning triangulated categories no no just a billion of categories without structure this makes sense without putting structure in the category is it true without putting any yes this is true because a abstractly a category is a particular case of infinity category however one has to be careful namely if if the index set is not filtered when you if you if you're if you're taking a co-limit of abstract categories you may of just categories you may end up with a higher category so if the cat if the family of indices is filtered then you will stay within ordinary categories but I still don't see because in the co-limit every object cast from has given one no so it's so one has to be again I'll say in a moment so again this is a technical discussion that okay so what I wanted to say is this that so which world are we in we are in the world of categories that admit all co-limits and this co-limit is taking place in that world so so it's co-limit again taken in the world of categories with all co-limits you can explicitly describe it as follows if these categories are compactly generated but now are they triangulated they have some extra structure what kind of category are you looking are they presentable stable or not they again so that's statement about presentable stable infinity category this is this is a statement about presentable stable presentable cat infinity categories all right okay so precise statement so these functions are necessarily commuted with co-limits because they're the left adjoins and you don't need anything else uh so we are taking we are taking the limits and co-limits in the ambient world of well let me call them dg categories with that contain all co-limits and let me just say one remark but what are what are functions in this category are they functions that commute with co-limits so in this category let me say let me assume for simplicity that we take the functions that commute with all co-limits and in this case i'll so okay i want to simplify things let's let's take that let's assume that let's say that we take functions that commute with co-limits in this case we require that both of these commute with all co-limits although this can be made that can be relaxed yeah so let me just say address opera's question so precisely in this setting suppose these categories are compactly generated like in our case we take some small category and we our c alpha is is obtained as in completion of this sub some category of compact objects so then you can describe this co-limit taken in the world of categories with all co-limits as follows you take the co-limit in the world of small categories and then you take it into completion so in this world and suppose also the cat was in place of the category of indices is filtered in this world every object is really really comes for some particular alpha but in this world i am allowing taking co-limits of those so in other words in when i'm form forming this i'm taking i'm really taking co-limits of objects each of which comes from from c alpha as we do in the in the representation theoretic side all right so that was a useful digression about the nature of categories no it's really useful otherwise we don't know what we're talking about all right so now i want to introduce well the the desired modification of the left hand side so let me first introduce the symbol for it i call it the wittaker category in the fine-gross manian so and so let me say what it will be so and then i'll decipher the definition so it's sheaves on the fine-gross manian in the sense with i just introduced but we're taking sheaves that are equivariant against maximum independent against and on non-degenerate character chi so i'll decipher all i'll decipher what this means in a minute and it will be actually a full subcategory in the initial category so i should add the warning here that usually when you talk about the equivalent category the forgetful the functor of forgetting the equivalents is is not fully faithful but because here we're dealing with a group which is essentially nipotent this forgetful functor will be will be fully faithful so so this definition may look non-obvious for the following reason that well as we just discussed here our objects of our category are essentially of finite dimensional nature so there there are co-limits of of sheaves with finite dimensional support but here we're imposing an equivalence condition with respect to a group such that its orbits are infinite dimensional so we are kind of inherently dealing with objects of an infinite dimensional support so here some care well we need to take some we need to be cautious when giving this definition so i'll give the definition and then the question will be why does this category have any objects and we'll we'll discuss it in a moment so what do you mean by this so first of all because the group n is unipotent you can write this group in scheme as an increasing union of group schemes and i so for example in the in the case of SL2 this will be just the group of loran series and here we'll be taking loran series with a bounded degree of pole so whatever this equivalence condition is this will be again it'll be a full subcategor here and it'll be obtained as the intersection of the subcategories where i impose the equivalence with respect to this increasing family of subgroups so equivalence for the big group is just an intersection well it just imposes equivalence with respect to all of the subgroups so now i'll have to say what each of these categories is so well as i as we discussed here the fine grass manual itself is a union of finding dimensional schemes and for each fixed ni i can assume that all of my y alphas are are preserved by by the action of ni so we'll define this as basically but the same procedures here it will be the inverse limit under shriek pullbacks of sheaves on each of these y alphas with the equivalence condition so and now we are almost in the finite dimensional situation except that these groups are not a finite type but each of this and but so i have this ni acting on y alpha and this action factors through some group which is already an algebraic group of finite type with the kernel being pro-unipotent and so and finally i it's by definition the equivalence condition with respect to this quotient so and i'll say in in the moment well what i mean by this but here we are in a finite dimensional situation so we have we have well finite dimensional algebraic variety and an algebraic group acting on it so now what i mean by equivalence so pardon me so this there is no prime this this is the prime so this was infinite dimensional and i define it in terms of the finite dimensional quotient all right so let's pause for a second and so let me just decide for what this means in the finite dimensional situation so suppose well let me call it n prime suppose n prime is an algebraic group that acts on some y and what do i mean by this chi so chi is a homomorphism of algebraic groups from from to the additive group and so let me assume that n prime is unipotent as it is here so so so now we have to be a little bit more specific about the sheaf theory so suppose that we are either in the world of d modules or we are over a finite field so in the world of d modules on ga there exists what's called the exponential d module and in over a finite field there exists an artenschweier sheaf over ga so let me call them in both cases exponential so it's a particular sheaf on ga so now this equivalence so it's a full subcategory and it consists of all those objects f that have the following property it's not extra structure but property so so let me write it and then i'll write and explain what this notation means where act is the action map of the group on my y so what i want is that when i pull back my sheaf onto the product with respect to the action it splits as a product of what i had along y and the exponential and so the tiny remark is that because n prime was unipotent if this homomorphism exists it's it's unique and moreover all the higher compatibilities whatever they are are satisfied automatically so for a small smoke as far as i remember in the usual theory the last before back anyway the upper shrink is involves a pullback shift in the twist but there is a shift and so the shift does not seem to be because this is like a definition you would do is after star but it's after shrink it depends which chronological degree you put the exponential in no but if the space is infinite dimensional like here but it's no it's finer dimensional we already in the final dimensional situation you don't forget to pull back by kind pardon me you forgot to pull back by kind this x is an g i oh i'm sorry the exponential itself would be you may have to yeah it's i put it in the same chronological degree as the dualizing sheaf all right so this is what you literally do if your sheaf theory is d modules or if you are a finite field but what so but in this talk i want to be as i said on the betty side and i'll actually want to work over complex numbers with sheaves in the classical typology where this will not literally make sense so now i'll explain the remedy how to make sense of this exponential well when you don't have but when you don't have the exponential so it's based on the following trick so i call it the passage from whitaker model to kirilov model although i'm not sure the terminology is very accurate so let's consider the following situation so so suppose you have again the variety y on which just the group g a acts so i'll consider basically a baby model of this and it'll be quite easy to see how to combine this with what i said before to produce an actual definition so in this situation we can't talk about whitaker of y again the definition of mean sheaves on y which are where chi is the identity map from ga to itself so this makes sense but so but now i would and again this definition makes use of the exponential object on ga so but now i would like to replace this definition by something else that does not involve the exponential so and but you need an extra structure on y and that extra structure is the following that instead of just having an action of ga will have an action of the semi-direct product suppose you have this acting on y where gm acts on ga in the standard way so in this case i'll introduce something i'll call kirilov model of y and it's the following it's a full subcategory inside sheaves on y which are gm equivalent and it consists of the following objects that these are those objects such that if i average them against ga so there are two kinds of averaging she can star out use star you get zero well it's another category so there are two forget well let's say you have wittaker of y it sits as a full subcategory inside sheaves of y there's a kirilov of y yes so first of all shriek and star don't matter either or according to what you said because the two pullbacks differ by a comological shift so but now yes gm is not unipotent and when you define that you it's the high tech definition so you need some dissimplification yeah same dissatisfaction yes so we have these two categories but now there is a general lemma that says that there exists a canonical equivalence as abstract categories abstract meaning they're not at all the same as subcategories here that sit very differently but abstractly they are they're equivalent and the two equivalences are are so let me just say the diagram does not commute that's what i'm trying to emphasize there yeah the two entities are equivalent let me say what the functor is in this direction it's the functor you take wittaker sheaf and you you star average it with respect to gm and so as and you as you can see in the kirilov model you never you no longer mention the exponential and so that definition makes sense uh well or an arbitrary ground field and so let me so you pull back to gm cos respect and you pull back by apple star and lower and push over by star yes yes yes star averaging it's the functor right adjoint to the forgetful functor uh functor forgetting the gm equivalence and so by combining these ideas you can see that in our case there is this extra gm basically that comes from the torus you can give the kirilov style category here and so the definition actually makes sense however i'll continue writing wittaker uh but again so you should think of kirilov as the as the definition all right whoa it was a long time 20 more yeah all right so in particular we should take this action but this category is an action by the torus which one as you said you're gonna write it but we should compare this to that no the original category had an action of the torus and then i use this torus action to what which is like here you see yes why had an action of the torus and i could do two things i could take just wittaker and no longer have any action or i can use this gm action to write kirilov just like a philosophical question the wittaker implicitly seems to depend on the choice of the character chi but the kirilov doesn't seem to depend on such a choice yeah so in the kirilov you're saying kirilov does does not seem to depend on this choice yes indeed so suppose you are in this situation then suppose you have two characters that are conjugate but element by an element of gm so it's easy to see that the corresponding wittaker categories are equivalent specifically by means of the action by that element of gm so if you wish in this situation wittaker also explicit does not depend on the choice of chi yeah what's the language at some point the choice of chi should admit it no and that's a remark that i forgot i'll i'll add it right now so as peter is saying is that so my definition seems to depend on the well on the choice of chi so what was the sky so i said it was supposed to be yeah so i didn't specify what chi was so now let me say what chi was okay so it was supposed to be a character to ga and i said it was non-degenerate but which which one do i mean so first of all it's a character therefore it factors through the cometant and if you take the maximum independent modulo it's the cometant it's canonically the product of copies of ga according to vertices of the drunken diagram so so and now okay so now you apply this sum map just some overall vertices and now comes an ugly step well you'll want homomorphism from loran series to ga and well the ugly way to say it you will say okay i'll take the coefficient next to t negative t to the negative one but that involves a choice choice of coordinate and that's not something we want to do so we want to do we want a more canonical procedure so the thing would be canonical if instead of well this is basically loran series so this procedure would be canonical if instead of loran series we had loran one forms then the residue would be canonical and so this is what we want to do and for this we modify so to do this we modify our picture a little bit so we so to have a canonical residue we twist everything so namely as i said so we have a curve x and over curve well implicitly we were considering the constant group scheme g but instead of that we'll twist g by the adjoint action of the torus using a specific t-torcer so which one well how do you get t-torsors you can start with a line bundle and use a co-character so we'll as a low line bundle we choose once and for all a square root of the canonical bundle on the curve and we'll use the co-character two row so this is this is the torsor so two row is homomorphism from gm to my torus so i start with a line bundle which is a torsor for gm i induce and i get a torsor for t so and if you perform this twist then you will see that well unipotent group will also get twisted and you will see that these loran series will be will get replaced by one forms so in this sense the procedure becomes canonical so i choose a square root of the canonical bundle on the curve yes it's a line bundle i.e. gm torsor and i i used two rows homomorphism from gm to the torus i induce the torus i get a t-torcer on the curve so then i have a i have my group scheme g and i use the adjoint action of the torus on my group to to get a non-constant group scheme namely i twist my so if you do this if and if you consider the corresponding version of the fine grass manian then this character becomes canonical because your unipotent gets twisted by this row so basically roots of groups will no longer look like loran series they will look like one forms and or in some of the groups row which which doesn't exist yeah yeah yeah a simple co-weight but it may not exist as a co-weight but two row does and for that reason i need to choose this again how does kai even enter in the definition of the correlative model but does it just not enter in so you're asking so it's that gm that will let's postpone this because all right so let me make a few remarks so we might not even get to the quantum situation but please tell say this story properly so so i gave the definition of whitaker but so you can ask well why is this category non-empty and so let me make an argument that in fact it is kind of empty and then i make and then i explain that it's actually non-empty so if you consider the category and the fine grass manian or any in scheme so this category has a t structure so namely an object is declared to be homologically greater or equal than zero if and only if well remember remember an object here is a compatible family of objects on what we're called y alphas under shriek pullbacks so and we can think of this this compatible family is shriek restrictions of f to the corresponding y alphas so we say that an object is homologically greater equal than zero if and only if all of these restrictions are homologically greater equal than zero and when i talk about the t structure on the particular y alpha i mean the perverse t structure so now you can prove the following general simple emma that every object f in this whitaker category is homologically trivial so it's an epidemic spreading here so so i said this category has a t structure and for that reason for every object it makes sense to take its individual homologies i'm saying that for every object in my whitaker category all of its homologies are zero however the trick here is that so the t structure here is what's called non separated there are objects that non zero objects such that all of whose homologies are zero but the object itself is non zero a typical example of such is that dualizing sheaf so um so it's and i'll say in a moment homologically trivial it means that well we have a t structure for every object and take its individual homologies they will all vanish and so let me say that this is one of this so i learned two main things from jaco blurry one was well to operate with infinity categories but here this is not what's going on another thing that to learn from him is basically how to take care of negative infinity and that actually already appeared in peter's talk in response to offer his question about sheaves being sheaves of hyper sheaves so well before i met jacob i would write this mysterious symbol db of some category and i would i was hoping that this mysterious letter b would basically take care of things that basically i was i kind of had this belief that you writing db is kind of it's some kind of rule of hygiene and if and if you observe this rule if you just write it meticulously you will not get sick and everything will be fine but then i but then so adopted new point of view that so being being hygienic you're trying to get rid of some bacteria but some of these bacteria are really helpful and and these bacteria live at comological negative infinity and that they give rise to a lot of mathematics so if you were to work with bounded derived categories you will never see this but a category okay but now let me give you give an example of this object also answering peter's question perverse on on finite dimensional pieces so let me give an example of an object this is the basic object there so let's consider the orbit of the of the unit point of the fine grass manian by means of the independent group and it's usually called s0 and let's denote by i the local well it's it's also in in scheme and this is in locally closed embedding so the sky gives rise to a map to ga and all right so so now i'll write a scary symbol on the board and i'll try to decipher it so i take the following object in the category of sheaves on s0 i take chi up a shriek of the exponential so what do i mean by this well that's an example of an object which is well if it was not exponential if i took the dualizing shift that would be that dualizing so what do i mean by this well s0 itself is a union of finite dimensional pieces and as we said the category on s0 is this inverse limit when i say dualizing well i was i'm supposed to specify objects on each of the fine dimensional pieces that construct as comprises zero and i take the dualizing and this dualizing tautologically shriek restrict to each other and well the same happens for any shriek pullback so that's what this guy is and so let me just note the basic object delta zero it'll be where i lower shriek is the left adjoint which a priori is partially defined to the functor i up a shriek that is always defined in our category but in this well you have to prove that on this particular object this left adjoint is defined why is it partially defined well we have a functor it may or may not admit left adjoint this left adjoint is defined on some objects but you assume in your general setup that you have those in the c alpha discussion the well the lower shriek but this is not a part of this this is the locally it's a locally closed embedding so let's say in the world of d modules where we have non holonomic guys lower shriek may not be defined on all objects in the better side is always defined and moreover you can do the same produce objects what i call delta lambda where lambda is a dominant co-weight so it's a usual trick well familiar to people notomorphic forms that you can do it so if lambda is a dominant co-weight the sky gives rise to a map from s alpha where this is the orbit that means of the unipotent of well i hope you know what i mean by this it's a point in the loop group that corresponds to co-weight lambda and the t is my notation for the coordinate on the formal disk so so it will be kind of s zero it'll be some comological shift here so so i said that the objects of my category are comologically trivial yet when i view them as objects in the ambient category yet one can prove the following that so you can ask so so you want a homomorphism like this which is equivalent with respect to the given homomorphism chi on n and it exists if and only if lambda is dominant it's kind of usual game in castle menschallek a formula so lemma so please pay attention there exists a t structure on whitaker let me say such that an object f is comologically greater than equal to zero if and only if homo lambda so you can create a t structure on my category which is so to say generated by this object delta lambda so again from the point of view of the initial t structure my all of my objects are trivial yet this what's taken on its own the category that obtained has its own t structure generated by this object's delta lambda so now i'm out of time so we didn't get to any q but let me but at least i can state a theorem so that theorem says this that and this is this theorem is true again in any of the shift erratic context so my desire to state on the betty side had to do with q deformation but we didn't get there the theorem is that there exists an equivalence of categories and that happens at the derived level which is t exact so the category representations has its usual t structure and the whitaker category is it has a t structure defined right here and moreover under this equivalence these objects delta lambda go over well to the usual irreducibles note that lambdas were dominant co weights for g which is the same as dominant weights for g check so kind of the level of parameters that make sense and now in the demodal setup so the usually people work with autonomic or autonomic regular and and there are also big big quasi-query and demos yeah that means that they are coherent which are not aeronomic of course so now in the on the representation side only reducible representation correspond to nice things well i don't know but how can it be that you can allow non yeah so what happens is that in this case the objects of my whitaker category are automatically in the holonomic it happens automatically well basically for the following reason that well on each orbit of n of k well your object all of your objects are because yeah because of the covariance yes the in holonomist is forcing you by the equivalence condition this is this question that i wanted to comment on let me see there's few more just one one that's point number two and there's also point number three okay okay now i already forgot your questions what was it monoidal okay can we so i'm over time can we declare it over and then this these will be questions this is a question period a question period you didn't all right so that's okay monoidal structure so as stated this is just an equivalence of stable infinity categories it's interesting but there are more interesting things to say so namely this is indeed a symmetric monoidal category and you would like to see the the structure here so unlike the usual geometric satake where we had convolution this is not even naturally monoidal category so and here but enters a new world and that of factorization categories so what you so as we saw this category was attached to a point on the curve and there is another the whole new structure there so we allow this well we put we'll allow these categories at a moving point and in fact at multiple moving points and that's what makes this what's called a factorization category now every symmetric monoidal category also gives rise to to a factorization category and so the actual theorem is that we have an equivalence of factorization categories so I should say that what that captures is not the symmetric monoidal structure here but the braided monoidal structure here it actually makes difference at the infinity level so you recover rep g as a braided monoidal category so that's that was that question now luke's question is this so let me juxtapose it with the previous equivalence so here we had this let me write a slightly more complete answer to your question okay so I don't want to work at the abelian level I want so you have this entire what's called spherical category and well this category acts by convolutions on on just sheaves in the fine grass manian preserving any kind of equivalency that you put on the left see this this is really a monoidal category that acts here and in this monoidal structure this monoidal action is in addition to the factorization structure so now let me tell you what it corresponds to on the on the right hand side so as I said this category is not equivalent to rep check it's equivalent to something else so let me tell you what it's equivalent to so this is well quasi-co but you need this intco correction on the following I'm sorry to say dg stack it's point times point over it's a fiber product of a point scheme times point scheme over the Lie algebra divided by the joint action of g check whereas this should be thought of quasi-co of point times g check so because this is derived scheme who's underlying derived stack with underlying classical stack is just point more g check the heart of the t structure is exactly that so that's why originally when it passed through the heart of t structure you see that perverse sheaves are equivalent to rep g check but at the drive level you see the whole thing so we have an action of this and it corresponds to the natural action of this on this so basically you have y times quasi-co herring sheaves on y times y over x always acts on quasi-co herring sheaves on y it's the usual convolution action so this is the pattern that's how things fit all right these were two questions and there is one more question that nobody asked but i wanted to comment on so so and the question is do you really have to go that big to have this equivalence do you really have to do whitaker do you want do you really have to do equivalence with respect to this huge thing n of k the answer is yes and no so if you are at a fixed point you will be able to replace n of k by something much much smaller in fact by many things that are much smaller and i'll tell you by what but this kind of description will not be compatible with factorization so if you want factorization you really need n of k because n of k is the object that factorizes so let me tell you what you can replace n of k by so in fact you have many choices one for each natural number so you can replace them by some subgroup that i'll call i sub n so let me tell you what's the i sub n is in the particular case of s o 2 so n is greater than 1 for s o 2 it looks like this it's a subgroup of matrices a b here it will be t to the minus mc t to the no t to the minus mc t to the 2 mc d where a b c d are in all so you make the positive part larger and larger then grows and the negative part smaller and smaller and each such each of these subgroups also has a homomorphism chi into ga and you can play the same game imposing equivalents and the resulting category will be just will be the same as whittaker so in other words you can have a purely finite dimensional model for this for this whittaker category


What is the role that a CEO plays to drive the culture of digital in an organization? Digital is a cultural change. It goes well beyond technology. It is ongoing. It's short-term, it's long-term and it touches all aspects of the business from the end to the end. But should start with the customer at the heart of it and then come backwards through the organization and then to your supplier base and then to the rest of the ecosystem. It has to be led by the CEO along with a passionate chief digital officer. And the CDO must eat, sleep and breathe digital. That is extremely important. And if we are to create a digital mindset, we've got to move from thinking digital to doing digital. Now we've got to also remember that technology or digital technology can change very rapidly, but people take a much longer time to change, which is where culture comes in. Which is when, therefore, it's a human resources issue as well. It's been driven where people understand that the change is required because it's good for the organization and perhaps there will be an evaluation either through your performance appraisal or otherwise built into some mechanism where the change of mindset must take place. It has to be digital first, which means there's a sense of urgency attached. It should be pervasive, which means it's across the value chain and you've got to keep repeating it. Ultimately, you've got to create a data-driven organization. But just to go back, the customer must be at the heart of the decision-making process. So it should never be digital for the sake of it. It should be digital because it provides value to your end customer. How do you get the rest of your leaders to start thinking about digital, start accepting that we need to move from, I'm not saying it needs to be a 100% shift, but move to sort of a hybrid model, change your mental model, interact with the younger generation, become more aware about what are the new innovative practices? How do you get the next line of leadership to start adapting their old ways to the newer ways? The environment of today has created a lot of that mindset of acceptance. So the acceptance is already there. Then it's a matter of creating cross-functional teams to deliver better to our customer. It couldn't be anything, let's say on warranty, for example, where they're getting their warranty clearances and time. So a cross-functional team led by the leader, but to make sure that the youngest person in his or her organization was also part of the team. And then we got the chief digital officer to put one member of his or her team. And this five-member team then came up with a solution, which was an app in some way that got developed. So the leader, the n-1, the n-2, the acceptance is there. The question is how do you create involvement and then do a defined result in a defined time period. And with keeping the customer at the heart, now we just need to do it faster, better, and just with greater amount of dexterity.


And so, my fellow Americans, ask not what your country can do for you. Ask what you can do for your country. My fellow citizens of the world, ask not what America will do for you, but what together we can do for the freedom of man. I'm the Major Andrew Champion, Deputy Commander of the 210 Field Artillery Brigade at Camp Casey, Korea. My choice to serve in 210 has provided me the opportunity to work with the best officers, NCOs, and soldiers of both the United States and Republic of Korea. During my short term here, I've experienced the best of Korean culture, including food, history, and baseball. Ka-chi-ka-chi-da, controlling the best, second to none. Second to none, I am Lieutenant Colonel Rich Farnell, Commander of Second Battalion 18 Field Artillery Brigade. Coming to Korea and being part of the Second ID team is by far one of the best experiences of my career. Not only do I get to work in the atmosphere of great camaraderie and combined fellowship, but I get to train with the best of the best alongside our Korean counterparts. At 218, we provide multiple large rocket fires to protect our nation's interests. And if I am not training, I'm enjoying the Korean culture and taking part in a plethora of activities, such as team sports, mountain climbing, and visiting theme parks and historical museums. This is a great place to learn, fellowship, and grow. Ka-chi-ka-chi-da, second to none, controlling the best, mission ready. Hi, my name is Captain Kimberly Day and I'm currently the HHV Commander for 218. I love being a part of 218 for two big reasons. One, the complexity of the mission set here, and two, the culture. Both times I've been here stationed in Korea, I have made history on this peninsula, deterring the North Korean aggressions with real life powers. But secondly, with all the amazing things to do here, there's food, there's culture, there's always something for everyone here. Please consider it 2ID next time you're back at the next ID station. I hope to be in your shoes one day here back in the peninsula, second to none. Hi, I'm Andrew Evans, I'm currently the Sunday of PSB Executive Officer here in KKC South Korea. Currently we're here supporting the best of the war, the 210th Artillery Brigade. Our goal of the main mission is here to ensure that the division is ready to fight tonight. I personally chose to be here in Korea because of the people who did experience the culture and to just travel the world. And then of course I feel that I can make a difference here being on the peninsula here in the 210th Artillery Brigade. Second to none, I'm Lieutenant Colonel Jason B. Washburn, commander of 1st Battalion 38th Field Artillery Regiment here on KKC in Korea. I just want to take a minute to talk to you about several of the opportunities that we have here in Korea. From having the only combined division and brigade staffs in the Army, we get to work side by side with our rock counterparts on a daily basis. At the battalion level our requirements to generate readiness and maintain readiness for our fight tonight mission provides more opportunities than anywhere else in the Army to learn and do our jobs on a regular basis. We look forward to you wanting to join the Second Infantry Division team second to none. Hey everybody, Major Josh Essling here with the XO for 637FA 210FA Brigade. Reasons I like to be part of the 2ID team. One, cultural opportunities here in the Republic of Korea. We have a bunch of UNESCO World Heritage sites here as a history buff. I've been to many of them, a lot of them within a short little drive. Two, the people. Most people have a short time here. They come in, they're ready to build relationships quickly and get the job done and make their impact. And then three, the organization as a whole. Even though we have our important mission here, we're mission focused. We also want to try to bring as many complete families here as well to try to extend that time with people being part of this team. Hey, I'm Major Jeff Morgan. I'm the XO for 210. Korea was at the top of my list because the mission is clear. Just out of the DMZ we know exactly why we have to be ready every day. The other key reason really is family. South Korea is an amazingly advanced, diverse country. With the long history, lots of culture, so many things to do on a peninsula. And then Seoul is also a perfect logic point for traveling and exploring the rest of Asia and a lot of the Pacific. Hello, I'm Stephanie Couch and I'm the Brigade Surgeon here with 210. You've heard all the great opportunities and availabilities here in Korea from everybody else. We look forward to seeing you here in the Second Infantry Division or second to none as you're considering your next opportunities for assignments.
