The final improvement to the simple Brayton cycle that we will take a look at will be one that will combine regeneration, which is what we just looked at, in addition to intercooling and reheating. Now just like we said when we were talking about the regeneration, this is an addition that you would only do for ground-based stationary gas turbine, industrial gas turbine systems. So if you're called back in lecture 9 part 1, we talked about reversible work output for a steady flow device and we came up with the following equation for reversible work output. So we had new DP and that was reversible work. So if we have a process whereby we're either doing compression or expansion, we can either minimize the amount of work that we have to do in compression or maximize the amount of work being produced by playing with the specific volume in this equation. So what we said is that what we want to do is either minimize the amount of work in a compression stage or maximize work output in a turbine. What we can do is we can adjust the specific volume and so if we're in a compressor, there that would be a case where we want to minimize the amount of work that we're doing. So the way that you can minimize the specific volume is by playing with the temperature. So if you move the temperature down or you cool the gas, then what that will do is that will minimize the amount of work that you're doing in compressing and so that brings in the idea of intercooling that we will look at. And the other part is if you want to maximize work out, again in that case, you want to move your specific volume up and the way that you can do that is you can increase the temperature. How do you increase temperature? You go into what we call a reheat cycle. So intercooling can reduce compression work, reheating can maximize turbine work output. So let's take a look at the process schematic and diagram for those two. It's going to be kind of a complex one because we've got a lot of stuff going on but we'll work our way through it. So there is our process schematic and you can see what we now have is multi-stage compression. So we have compressor 1, compressor 2, and we have multi-stage expansion, turbine 1, turbine 2. After the first stage of compression, what we do is we go into a cooling process in our intercoolers. So we're rejecting heat, cooling the gas, reducing the specific volume, then going into the second stage of compression. And then in the case of turbine work, what we are doing is we are going through a reheat process and in the reheat process we would add more fuel. We would then combust again, heating the gases up and consequently that would then increase the specific volume, giving us more work coming out.  So that is a schematic of the process. The TS diagram, again it's going to get a little crazy because we've got a lot of stuff going on but let's take a look at it. So this is our TS diagram. What we're doing, I'll walk you through this. We start at state 1 which is the gas coming into our compression. So there's state 1. We then compress and the first compressor taking us to state 2 on our schematic is there. We then go into an intercooling so we're reducing the temperature of the gas. That brings us to state 3. We then go into another compression stage taking us to state 4. We then go into combustion. So now we do have reheat as well and what I'll do, I'll draw the reheat here. If we're in an ideal world it would take us up there but in reality we won't go that high because our regenerator would have some certain effectiveness. But we will go into a combustion process taking us up to state 6 after combustion. We then go through the first stage of expansion through the turbine taking us to state 7. We then do a reheat process which is another combustion process taking us to state 8. We then come through another turbine taking us down to state 9 and then finally we go into the regenerator and taking us to either 10 or 1 in terms of exhausting. So that is intercooling, reheating, regenerating all in with the Brayton cycle or the gas turbine cycle. The thermal efficiency of this cycle you would have to go through and calculate depending upon all the different parameters that you might have. The other thing is that you could add many many many of these stages. However the thing that you have to balance it with is the complexity and the increased economics and costs of having this type of design as a trade-off versus the increased thermal efficiency and reduced fuel savings that you may gain. So that would limit the number of of reheat or intercooling stages you might go through with a Brayton. But that is the Brayton cycle and that will conclude today's lecture. Thank you very much.


How simple is it to make a Copic ice cream cone? It is really simple, 10 strokes. Just create a couple of swirls for the top section, a cone, and a simple shadow for each one. And boom, you're done. Happy summer.


Hi everyone, this is Chichu. Welcome to my channel. Now what we're going to do for this video and the next video coming up I just had another session with my student. This is would be our third session online and this is a former student that got in touch with me and he's a university right now He's taking some courses one of them being economics and some other courses as well and we sort of already Put out a video sort of doing a little intro to our discussion and my student had has agreed to share some of the information that we're talking about some of our sessions online with you guys right so I've been recording these videos these sessions where I've recorded our first session and recording this is our third session and for this session he had some questions regarding his econ homework his econ assignments his econ labs and they ended up being math questions so what we're about to do is take a look at some of the mathematics that we talked about during our session and this is sort of related to a lot of the videos that we've covered in the past so I thought this would be a nice little segment to add on to our collection to our our math content okay so in this video specifically what we're going to do is talk about how to graph a line there's a you know he's doing assignments he's doing labs and they're basically starting to put equations functions online on on graph's Cartesian coordinate system and the first place they're starting is to graph a line so in this video we're going to take a look at how to graph a line okay and in the next video what we're going to do is look at how to solve a system of linear equations and we've already I believe put out videos regarding that as well right so there's going to be two videos coming up the first one being how to graph a line how to put a line on a graph and how to do some simple calculations and the second video coming up is going to be how to solve a system of linear equations okay and there will be a lot more content like this coming on in the future as we tackle some of the issues that my student might be having maybe regarded to econ or other subjects or life in general at university that he's dealing with okay that's it for now I'll see you guys in our little exercise session right now and in the next video bye for now


My name is Jeremiah Sumerian and welcome to harsh critique. Oh boy. The article I have to look at today is something by a individual known as a witness. And witness is a scp049 super fan who has actually asked me, they're a patron, asked me specifically to tear apart several of their drafts. And well, since they're a patron, I've agreed to do so. So to make a point, by the way, this article is actually on the wiki right now at plus 92. So take that as you will. But it's called boiled scrambled and fried. SCP049 was sick. For the first time in its stay at the foundation, there was something clearly wrong with it. Over the security cameras that had been observed holding its stomach and moaning, limping around its cell and stopping occasionally to lie down. The medical staff didn't know what to think. There was nothing noticeably off about the plague doctor except for the strange stomach pains. It didn't help that there was no way to get access to its body beneath all of its skin robes. That's a phrase I never thought I would say. SCP049 was taken to the medical station for a proper examination. Oh, a proper examination. I see. This caretaker was Dr. Richard O'Mell, which f***ing omelets. This whole thing is about eggs. Who specialized in the care of humanoid anomalies?  I can assure you I am strong enough to withstand the pain. SCP049 struggled against his restraints as Dr. O'Mell examined him. And then we come to Dr. O'Mell, who, I'm sorry, given the dialogue, which is really bad, I can only hear as like a surfer dude. So it's like, man, what happened to you, 049? This is bizarre. That's nothing realistic about that, by the way. What? Man, what happened to you, 049? This is bizarre. I mean, let's just break it down. The articles writing outside of the dialogue is, well, who cares? But the dialogue is so bad. It's not realistic in any way. It doesn't sound like real people talking. And while I get that this is supposed to be super weird and absurd, that doesn't mean you can write badly when you're doing it. Man, what happened to you? Who talks like that? Who looks down? Oh, there's a man. Man, what happened? And even if someone did talk like that, it wouldn't be a doctor at the SCP Foundation. This and this is bizarre. I love how the characters in the dialogue here always state things that are blatantly obvious to both the audience and all of the characters who are present. You don't need to say this is bizarre. 049 is doing something weird. We all noticed it. That's why you're there. Oh, man, I felt the lump in SCP 049's stomach because he touched the doctor with his gloved hand. Abdominal distention, maybe? SCP 049's breathing became labored as it spoke. I'll be fine. This has happened to me before. And I promise that it's no disease. Then you know what's happening. Why didn't you tell us? Dr. O'Mell stopped touching it. Well, that's an indefinite pronoun that makes that a really weird sentence. I'm not really sure if you're talking about his stomach, if you're talking about 049 in general, or if you're talking about something else. Oh, for fuck's sake. I did not think you would believe me. So I said nothing. Doctor, I'm pregnant. So already, I can tell this is SCP 049 fanfiction. And a particularly weird branch of it that involves, I think, I think it's male pregnancy. I mean, maybe just be that. It's like a basic descriptive term. Oh, wow. You're what? I'm sorry. I can't explain it. Please just let me return to my cell. I need to make the proper preparations. But how can you be pregnant? We haven't let you out of our site in months. SCP 049... Oh my God. No one talks like that. How can you... He's again stating stuff that everyone already knows. We haven't let you sit out of our site in months. We know. You know. He knows. Everyone watching knows. Everyone... And even if the reader doesn't know, because it's not contextually included, you don't say it. That's the whole point of... When someone says, show, don't tell, this is what they're talking about. SCP 049 tensed up and began breathing heavily. It looked like it was in intense pain. It looked like it was in intense pain. Oh, you see the problem with that? Oh, man. I love this. So there are three reiterations of the same concept, but done differently. So SCP 049 tensed up and began breathing heavily. That is fine. There's nothing wrong with that. Everything after that and that entire paragraph is bad. It looked like it was in intense pain.  Don't tell me what he is. Tell me what he's doing. And then, of course, you add on, 049, are you all right? Because he's in intense pain, of course. 049, are you all right? I mean... All three of those sentences communicate the same thing to the reader. And two of them are unnecessary and two of them do it clumsily. Don't concern yourself with me. This will only take a moment. SCP 049 ran out of the room to retrieve more members of the medical staff. Not sure what they're going to do to help you, but okay. SCP 049 continued to struggle and gasp in pain until it shuttered and let out a cry. Now, 049 and the others returned just in time to see a pearly white egg tumble out from beneath its robes. SCP 049 recovered quickly and spoke. Doctor, would you please free me from these shackles? I need to tend to the egg.   He was so shocked that he complied. Just what? And SCP 049 gently reached down to pick up the egg and cradled it in his arms. And then some other random doctor. We'll need to file a report about this immediately. Good to know I kind of figured as much. Breathe one of the doctors. This has never happened before. I mean, I feel almost bad for the person that wrote that. This has never happened before, as if everything that you've written so far hasn't made that abundantly clear. You're telling me, honestly, SCP 049 has never laid an egg before. And if he has, you gave me plenty of contextual information that this was surprising to Dr. Omelette. So why in the world would you say out loud, this has never happened before to the reader? Because no one in the universe needs to know that. Oh man, but SCP 049 slowly rocked the egg back and forth. The Foundation kindly allowed SCP 049 to keep and raise the egg for research purposes. What research purposes? I want to see how SCP 049 handles an egg. For the past five days, it devoted all of its energy to take care of the egg. It had requested fabric and paper, which the Foundation granted to it. And from those materials that made a nest in the corner of its cell, the egg was safely contained within the soft nest. And SCP 049 sat on it to keep it warm. Many scientists reported hearing soft clucking noises from the sp- Oh f**k you.  Dr. Omelette was standing in the o- I'm just gonna call this guy Dr. Omelette from now on. Dr. Omelette was standing in the o- Cause I mean, his name is Dr. Omel. Dr. Omelette was standing in the observation room, having come to write a report on SCP 049 after the event had taken place. It seemed healthy and the egg was in fine condition. Still, this was all very strange. Thanks. I hadn't noticed. Neither had anyone else. SCP 049 certainly- Why is this rated plus 92? This gives me so much- You know, I was- I was building up this hope that the SCP Foundation was doing better and better, but you know what? This is an object lesson in what I have been preaching for f**king months now, and almost a year now, that writing for the SCP Foundation is super f**king easy. Mmm. Cause this is not only succeeding on- This is not only like living on the wiki, it didn't just get to plus 10 or plus 20 or something. It's plus 92 and it's probably gonna go over plus 100. It seemed healthy and the egg was in fine condition. Still, this was all very strange. SCP 049 certainly had a bird-like appearance, but that mean it was really a bird? No!  The writer wants that to be the f**king case. I don't know how to confront SCP 049 when it began to softly peck at the egg. 049, could you explain to me exactly what you're trying to do? Dr. Omelette's voice- Oh, I'm sorry, I did that in the wrong voice. 049, could you explain to me exactly what you're trying to do? Dr. Omelette's voice crackled over the speakers in 049's cell. What needs to be explained? I was just checking for signs of life within the egg, which I found. SCP 049 stood up, returning the egg to its nest, and sat on top of it again. F**k you. For real?  What? I asked if you were a bird.   I'll leave it to you to decide whether I'm talking about the author or the character. SCP 049 thought about it for a moment. No, as far as I'm aware, I've never been a bird. I've never been a bird? What, like, what? Yet, producing eggs is natural to me. By the way, you know what really bothered me about that? Like, this is obvious. Like, I want SCP 049 to be an actual bird fan fiction, but the problem I have with it is that it's, like, so obvious.   There was soft, clucking noises. I lay eggs. But you know what?  Then how often does this happen to you? It's difficult to keep track of time, but I believe it has not happened for decades. Oh, I see. Dr. Omelette couldn't believe that he was actually... I can't believe the... Dr. Omelette couldn't believe that he was actually writing all of this in an official report. I can't believe that the author wrote this down on an actual article. SCP 049 began humming to itself as it rocked back and forth on the nest. Ten days after the egg had emerged, SCP 049's cell was filled with researchers holding cameras and taking notes. A glass shield ran through the middle of the room, keeping them safe in case 049 made a move and multiple guards were on standby. Today was a big day. Whatever was inside the egg was going to hatch. How do they know that? No idea. You don't give me any information on that case.  SCP 049 stood protectively over the nest while the researchers whispered to each other on the other side of the room. I want you to remember, as I read further, that there's a glass shield separating the researchers from SCP 049. They literally cannot cross over to where they are. And they can't cross over to where he is. The egg was shaking as a crack in the center began to grow bigger and bigger. Finally, something began to break through. A white beak broke free of the shell and then the creature inside tore itself free with its arms. It was another plague doctor. It was small and looked kind of funny and looked kind of funny. Any time, let me just give you a free tip right here. Any time when you are writing something, you write down what something looks like. And that includes in an SCP document, by the way. But this is a tale. But even in an SCP document, that is the wrong thing to do. You have made a poor decision. Don't do it again. It was small and looked kind of funny. And compare- is it- is it looking that way? Or is it just kind of funny? It was small and looked kind of funny in comparison to its father. SCP 049 let out a gasp of excitement and picked up the small doctor, hugging it in its arms. Should- should we do something about this? I don't know. Why? Just as soon as the excitement reached- What excitement? Why would- Just as soon as the excitement reached its climax, the doctors in the room realized they had just witnessed. They just realized this? They didn't realize it immediately when they saw another one come out? They had just witnessed the birth of a new anomaly that they knew nothing about. Why was it wearing a hat?  Dr. Omelette was the first to step forward cautiously. 049, would you please put down that thing? I know you must be excited, but we need to observe it in. Dr. Omelette began reaching towards 049. Whoever treated when the small plague doctor in his arms spun around and smacked his hand with a stick. Now attach the doctor. Small doctor leaped from 049's arms and swiftly exited the cell before anyone could react. So two things. Remember that glass partition that separates everything? What the f***? That's all I got to say about that. So somehow, even though this glass shield separating them, he was able to reach out towards 049.  Because that makes sense. They left the door open on 049's side of the shield. As the containment breach alarms blared, 049 wiped a joyful tear from one of its eyes. He is the cure. This is not funny. This is absurd. This is a bad tale. Like this is one of those things where it's like, oh man, the concept is really silly, but it's executed so clumsily. I hadn't read this until someone paid me to do so. And I'm really, really, really rethinking that concept. Anyway, see you in the next video. Bye.


What up, what up, Wimbush here. And for the past couple of years, you've been hearing me talk about Unroll Engine, and with Unroll Engine 5 out now, there's no better time to start learning this powerful piece of software. Your time is now. You know, Wimbush, you're right, but it can be really hard to learn a new piece of software. It can be really hard to know where to begin. And personally, I think the best way to learn is choosing a project you wanna create, and what that's gonna do is help you narrow your focus and give you constraints for what you actually need to learn. So learning with a purpose and a goal in mind will help you ask the right questions and not be overwhelmed by feeling like you have to learn every single button and feature in a software.  So how this is gonna work, we're actually gonna provide you guys with a template file inside of Unroll Engine. We're gonna provide you with the camera move. We're gonna give you the pug statue that goes in there and everything else that you need to get started. You wanna make sure that you stick to the guidelines. We're gonna render this out in 4K, and you're gonna have one month to submit your renders and at the very end, we're gonna take all your submissions to put them together as an epic montage that will display here on YouTube. And to give you some incentive to join this challenge, we have an amazing lineup of prizes with a pretty epic grand prize. Starting off with third place, we're actually gonna have a loom pad, which is by Leia. It's a holographic display tablet. I've showcased it in several tutorials on my YouTube channel. And with this, you can actually take 2D or even 3D different renders and everything and have it displayed in a holographic form, which is really dope. And this could be absolutely yours if you get third prize. And for second place, they're gonna be getting a one year subscription to Maxon 1. Now if you know me, you know I love Maxon. And Maxon's always been a huge supporter of creatives all over the world. And we're super proud to have them as part of this challenge. Now Maxon makes powerful yet approachable software solutions for content creatives working in 2D and 3D design, motion graphics, visual effects and visualization. Maxon's product line has exploded in the past few years and includes my favorite 3D app, Cinema 4D, also Redshift Render, Red Giant, Forger, and most recently ZBrush, the industry standard digital sculpting and painting solution. And for our grand prize first place winner, they're gonna get a brand new shiny Nvidia 3090, this thing is so massive. I can't, can you see it there? Yeah, it's right there, it's so massive it's taking up the frame. But they're gonna get a 3090 GPU from the amazing folks at Puget Systems. They're America's number one custom computer builder. They're based out of Seattle and they specialize in high performance custom built computers. They actually helped me build my very first PC. I've been on Mac for most of my professional life and I switched to PC just recently and I was super afraid to do it and the lovely folks at Puget were so amazing and setting me up with an amazingly fast 3D rendering mean machine and we are so happy to have them be a part of our grand prize sponsor list and we're so thankful to have them and Leia and Maxon to join us with giving away some prizes to our challenge here. So just to reiterate, that's a 3090 that's a full subscription of a year of Maxon 1 and that's a LoomPad holographic display. If that's not motivation to learn Unreal I don't know what it is at this point. Yeah, oh no, that's crazy. You gotta get off your butts and let's learn some Unreal. Got 3090, Maxon 1 and a LoomPad on the line, let's go. And because we want everybody to dive into the world of Unreal Engine your submission 100% must be done at Unreal. And be sure to tag all your work that you're doing for this challenge with the hashtag pugforest challenge. So I'm gonna go over the project overview and the rules right now inside of Unreal Engine. So first off, we're gonna have a camera move already in here so you don't wanna touch it at all because we want the montage to go seamlessly at the end and then we're gonna render out at 4K in which I'm gonna show you exactly how everything is gonna be set up here on Unreal Engine. So if you're looking at the screen right now this is the project scene template that we're gonna be using inside of Unreal Engine. You can see we have the pug statue right here. We actually have a ground plane right here. And if you follow through the tutorials that we're gonna provide for you I'm gonna show you how to get started from scratch with this scene and how to move everything through. But just to show you guys what the camera move looks like I'm gonna come down here to my content drawer. I'm gonna open up my timeline here and I'm gonna look through the camera. So this is actually the camera view that we're gonna be seeing. And if I hit play, you can see that we just have like a handheld camera move going off into the scene and everything's gonna be seamless. So if you can see right here it's gonna be running at 24 frames per second. And if I click on this clipboard here we're gonna come into the project settings. I'm gonna come into output and for output resolution it's gonna be set at 1080. So it's gonna be 1920 by 1080 but we actually want this to be switched over to 4K like so. So your final output resolution is gonna be 3840 by 2160. So be sure to keep an eye out to both of our YouTube channel so you can see exactly when those new videos and live streams go live. I'm so excited to be teaming up with not only WinBush but our sponsors to be able to put on this challenge and I cannot wait to see what the submissions are gonna look like. I can't wait to see all of these pug forests.


Okay, let's start on this session about space, space governance. It's part of the technology agenda at the World Policy Conference. We started, if you remember, 2016. It was around the geopolitical impact of data. Since then, the technology agenda has developed further in Atifri with the creation of a dedicated programme with Thomas Gommard, Annalise Pagnet. And then during this 15th edition, you saw yesterday technology around circular economy. You will hear about technology in energy, technology in healthcare tomorrow, and today's space. So when I discuss with Thierry about what would be a good topic, we very rapidly zoom in on space. You've seen, unfortunately, this year, the impact, the importance of space technology during the Ukraine conflict. It has been visible to all of us. Certainly not the application we would like to see, but at least it has made it visible. And in fact, space is going through a profound transformation. The one we've not seen since the inception of space, and it is driven by technology. As always, in technology, it's about cost. So the new technologies, be it electronic, be it materials, be it information technology, have allowed to reduce the weight, which is very important in space, and thus democratise the application of space. Now you speak of micro-satellites. They are about the size between the two of us, this thick, and you send 5,000 micro-satellites per year while we use to send 5 big, like this, satellites in the space per year. So it's a big transformation, big change. As such, it allows this reduction in cost, and the multiplicity of the capacity that is sent, not only in space, but then consequently on the operation on the ground, allow for the creation of new applications. One is clearly, as I mentioned before, the other one is exploitation of images, space images. You've seen how optic has improved, and that allows you to a level of granularity that opens new markets, new opportunities in space. It's just one example you will hear more. Now from a business standpoint, that's where I come from, if you look what space means today, and I refer, you can find the reference. It's a McKinsey report on space of August 2022, quite a good one, I recommend to read, stating that this is today 1 trillion, so a market. The expected annual growth rate is about 15% until 2030. Believe it or not, it still remains a respectable number. And there are 1,400 companies globally active in that market, with a lot of new entrants, thanks to the possibilities that I mentioned before. And these new entrants, what do they do? They continue to work on cost reduction. Again, that's what drives the adoption of technologies on an open new field. It allows the development of new business model. You will hear some examples on our panel today. And what we will see most probably is everything in infrastructure will go towards software defined, meaning you have a satellite, it's a piece of hardware, and you will equip it with the necessary capacity so that you can manage it from your software and then that allows you to extract more value and have more flexibilities and further reduce the cost of your operation. So that's the context. Now, there is obviously space started with the public sector, so there is obviously a geopolitical aspect to it. Every country is equipping themselves with space command, France recently as well, so everybody does it. And we see it and we will address it partially on this panel, but then you have civil operators coming in, creating a governance question that we will address on this panel. And to the point now that you have so much waste that you need to address waste in space, because we sent so many things, so that's a consequence. So it shows the evolution of that industry and the importance, the relevance for the World Policy Conference. So in order to address this theme today, I think we have a fantastic panel, and we will start by an introduction of Amir Algafri on my left, he is Senior Director of the Space Engineering Department at the Mohammed bin Rashid Space Center in Dubai. As the host, he will tell us the position of the UAE in space, the evolution, which is quite radical for the Emirati in it. Then we will address the governance question, starting with Professor Kazuto Suzuki, Professor of Science and Technology Policy at the Graduate School of Public Policy at the University of Tokyo, Japan, and Senior Fellow of Asia Pacific Initiative. Then his context setting will be complemented by Professor Daniel Andler, who is a Professor Emeritus at Sorbonne University and member of the Académie des Sciences Morales et Politiques, who will complement the governance part with more, as we know, Daniel, the ethics perspective, because it's a technology space and when there is technology, you always have ethical questions. So that will be the context setting, the governance part, linked directly to the agenda of the World Policy Conference. Then we will move in a second section or third section in defence and cyber security. Obviously, defence, it will be our friend Mayor Shetrit, a former member of the Israeli Knesset, well-known in the World Policy Conference, who has had numerous ministry positions in Israel, and he will address the element of defence. Complimented by Patrick Trancleur, Founder and CEO of SISEC, which is a cyber security company active in confidential computing and in full disclosure in the World Policy Conference, Carista Venture Fund, linked to the CNES, a sponsor of the World Policy Conference, is an investor and a board member in SISEC, and personally as well. So I want this to be very clear in full disclosure, as it is a rule. Then we will move to the civil application. The civil application will be addressed by Geoffrey Boucault, CTO and Group Vice President, Corporate Strategy and External Relations at Valeo, a very large well-known French company working with Automobile OEM. And then François Barrault will conclude the panel, the intervention of the panel, and the application is the chairman of DG World, a leading European think tank in digital transformation, also a well-known friend of the World Policy Conference.


All right, Tom here from Orange Systems and I have a special guest Xavier D. Johnson with Enterprise Offensive Security We have to talk about this windows DNS false. I needed someone smart and cyber security to help me with this We you know, it's 10 out of 10 bad You hear things like warm a bowl and you're like hold on Hold on Windows is starting starting to scare me a little bit here, but it may not be as bad as we think Right. Well, I hope so. So I'm gonna rely on a little expertise here. So that's why Xavier's here I'll leave a link to how you can find his channel information about him down below But let's dive into this Mess that is the cigarette. I think that's what has been called right cigarette. Yeah cigarette and it's funny I love the name of it. Yeah I mean because if you understand the bug then you understand the the severity of the name Yes, and we'll start with what is cigarette specifically calling to a signature record used in six zero RFC 2931 and Tiki blah blah blah. So we're looking at here is the signatures within DNS so you have a domain that domain has name servers attached to it and You know, for example, Lawrence systems comm and then there's NS dot Lawrence technology comm I think our NS one is our name server Now if I were to craft a payload into mine because I control my name servers So I can put whatever I want in this particular slot So to speak in the DNS and it turns out if you put something big enough in there Microsoft will think it's executable It starts to flow over into another part another piece of memory that it shouldn't And so it seems like you could just put a payload as a DNS record Yeah, and that's not how it should work. You should always sanitize your input So when you're reading something, especially out of the public space that is the internet where anyone can put anything in a record Proper coding and someone wasn't thinking about this about 17 years ago Yeah, it it basically allows this in there now I know some of you're going well good news my windows DNS server isn't publicly facing so I should be safe But that's actually not true either The exploit works by if you have a windows active directory set up and your hosts are all connected to that act directory that Pretty much means that windows server is acting as a DNS So any one of your clients no matter what level of protection they put on there They send their queries over to your Microsoft server and then it reaches out and grabs the well What could be a payload in the name server record and that's where the exploit problem comes in Yeah, and I mean this is the reason why you would use sig to begin with is To address the it's a need for DNS sec as far as I know. Yes. So just imagine you're trying to you're trying to You're trying to use security against security, right? So I mean, it's not necessarily that the DNS of Windows or Microsoft itself is vulnerable as much as it is the implementation of reading these records From the DNS. Yes. So the concept of DNS sec was to Establish like a better authority so we don't man in the middle of something. So we have a secure line Between making sure all right this name server is properly Tom's name server for his website So we know that the name server in a website and it's all working together We're gonna deliver you Validated records to make sure that this is the website you're going to but of course adding these extra signatures was the extra coding That meant we have to put signatures in there And we should these are like essentially security certificates that they put in there for validation. Yeah, there's a signature and there's a key Yeah, and but there apparently is also the buffer overflow. So what they're doing here is And how many times doing security research is this where you start poking and looking? I mean anytime you got input and output that's when you're supposed to that's where the rubber meets the road for security And if you're an aspiring researcher any time you figure out that a system is receiving data and or giving data That's where those are your sweet spots. So somebody thought about this and said hmm How is the domain? Actually handling DNS. I wonder if I can pass more data than what can be handled In that in the runtime when they're calling out the signature and here you go you get a you get a yeah heat-based buffer overflow and First starts usually you the first thing it happens when you've overrun the data is it crashes But the crash is the first indicator into will it crash but we spot Yeah, let's keep fuzzing away at it until we find out where the executable is and that's how we can start delivering a payload Into it and actually get the server to run something right it's called control flow right and if you can get you can actually Gain control over the flow of the runtime or the execution of a program then you own the program right because you're saying hey By the way go to this next memory address for your next instruction And if I own that memory address and I can actually send whatever instructions I like And that's where it gets scary because DNS is a server level function. So you get full system You know system you're running at the lowest or I should say highest level Functionality in windows, you know the ring zero lowest ring zero Yeah, and that's where you want to be because now you have control So once you've decided to execute something whatever you have executed in there Executes with that same level of permission at the DNS server runs out and all this is being done The users completely unaware of it because it actually doesn't affect the user's workstation. It directly attaches to the server It's executing at the server level not the workstation level right and that's where this really gets interesting right you're talking about a User a single user in your network in your environment being able to compromise the server upstream from it That actually affects the arrest of the organization So no longer are you worried about just a simple, you know ransomware on a single end point that may be able to be Contained to that single device depending on how you have your network set up You're talking about an entire complete network compromise from the click of the link or just from visiting a page potentially Yeah, and this is it's a really scary concept on there I mean attacking the DNS like this someone had asked me about why this is why this wasn't found earlier than 17 years and There has been other exploits. I know unbound I covered before I think in another video where unbound had a very similar one Where they found out there was a buffer overrun Under certain conditions which good news is I don't think for most systems It was a default condition But that in the Linux world was a similar problem where unbound would read the same thing It was DNS sex signatures Somewhere related in that area and someone found out an overflow because it is scary because the user goes all I did was go To the website and they there's not even a trail left on the user other than if you have to know the website to deliver the payload But I mean the hackers leave that evidence for you I mean in the world with malicious advertising and the fact that you know I could put a malicious add-on to a legitimate site and take advantage of this Vulnerability just for you visiting the site and that DNS being resolved on your network That's very very dangerous Yeah, so the Checkpoint research is some really good. I mean, we're not gonna go through every little bit of it But you can tell I'm like halfway down the page They walk you through each little piece of exactly how this is done, which I thought was great how they break it down It's really solid research, but it also goes to show something I brought for is why doesn't it find for 17 years? It's also because this is how much work it was to find this Right and There's definitely there's definitely a few more of these bugs hanging out out there Just kind of waiting wait wait for me to have found Zero days and I mean, you know you talk about the zero-day thing This is that and who's to say that this hasn't been used in campaigns before Where just people are being compromised from using this exact bug? I can tell you this there will be patches that come out. There'll be some people that don't patch They will be compromised due to this bug. I mean, we just can guarantee you that a 10 out of 10 warmable Windows 10 bug is going to be abused Yeah, we're gonna definitely see this use well in the other side that's gonna happen on this is Because this is so old this affects really old versions that are all well long past support long past patching But obviously still in use and I know when no one's turning off that 2003 server because it works No, so just a matter of time for someone releases a series of you know ads or whatever they want to start You know blanketing out this and getting users to click on it a couple malicious well-placed ads to weird domains I mean, you don't even really got to go that far if you got a Raspberry Pi And you can get somebody on your network and then do captive portal. Yeah Then you just force someone's device to actually connect to a network and then force their device to send traffic to a place That may have this vulnerability. So Become patch For this is patch or don't use Windows DNS. There's the only two Options now another question to come up I seen a few people actually asked me this was well Why do they release this research and the patch and the reason why it's really simple How many how many bad actors are watching patch Tuesday, which was yesterday or is that yesterday was patched yesterday All of them all of them. They would have found this anyways. They would have said So making I mean and if you and if you look at Win Bend X W. I n b i n d e x and you can pull this up If you want, I'm not sure if you've ever heard of this before but when Win Bend X is a Tool that allows you to be able to find all of the different binaries that were changed based on Windows updates If you give it a go if you want to share your window and pull that up for the people It's really interesting I just discovered it about two days ago and it's funny because literally a day before patch Tuesday And it's also funny You actually shared a link is it patched Tuesday and that was redirecting potentially at some point I'm not sure why but you talk about the ability to be able to get into traffic What's the domain again? Win Bend X. Yep. Be I n like binary. Why am I? Why am I thinking that? And there you go Yep, that's it. So, I mean, I'm not you know the most Windows-friendly person, but I can tell you that you know, even if you want to click on that blog post down there And I could tell you that this will be used and is used for you to be able to get a better understanding of What is coming out of these updates, right? And so something like, you know reverse engineering a patch It's becoming easier and easier and lower hanging fruit than ever and they're using tools. This isn't my skill set like Right Getting a list of updates how they do it. This is yeah, here's how you grab them and then okay They have some pretty simple instructions. I'll have to check this site out. That's pretty neat So yeah, if you want to give that one file a look. What was it? SIG Can't think of the exact DLL. Oh, they have a listen here. Look look at that Just type in SIG and see what pops up and then scroll down to the SS SIG Sign in control nothing yet. So it's probably a matter of time before you type in SIG and Either way, yeah, I mean, it's pretty powerful to find something. Oh, wow And when you can download the vulnerable version just in case you want to have a back door back into some systems, right?  So it actually would pass signature. So if you were actually I use it I get the I get what you're saying. You could actually unpatch a system, which is I guess super scary If you unpatch a system Microsoft may not realize a file was changed.  We're talking about targeted things So maybe I'm in there for six months just trying to get you to you know Just trying to get you to the holiday season so I can get you to the one page To get domain admin right or to further my access or whatever, right? And this is why I had you on here. This is what you do for a living So you're you go like those next layers deep.  So I have some customers that come to me that are breached hair on fire And then I have the majority of my customers come to me that have already been breached and they're like Hey, I never want to go through that again. Can you please help me? And then we work with them to put together a plan so that they can keep an eye on on things, right? Like there's no foolproof method to stopping You know attackers or attacks insider or external But what you can do is develop a program a security program within your organization that addresses these risks and then Document the ways that you've addressed these risks and continue to make those living documents and say hey You know as threats emerge We're going to need to add on to these policies to make sure that we're accountable and that we're being held accountable For all of the you know the potential risks that are exposed, right? I mean something as simple as a proxy may be able to save you from a You know attack like this or the single one liner that can be run that you know Sets the maximum size for DNS records. Yeah Little things like that. And I think the biggest thing is probably the when you have done the security audit It's almost always they're Unpatched like from last year not last week. So Most of it is There's a value in the security audit.  Yeah, you skipped a few and I think it's what people I think the There's a few every year. They do those, you know, what got breached like overused for a year and most exploits were ones that were over I think 50% of which are ones that are over a year old or the ones used. So sure. Yeah, a lot of my a lot I mean two thousand exploits from 2014 are still valid And then you also got to think about like beyond exploits, right as a security practitioner as a red teamer, right? I get to do things that aren't necessarily just find a service and exploit it I get to move laterally, right? So there's and there's some times where you'll make one compromise and then a Misconfiguration is the way that I'll get domain admin, right? And so like you may have had that one week service or you may have had that one person that clicked on the link And when I got on their host the rest of your network was flat You didn't use MFA to your services. You didn't proxy off all of your sensitive things I was able to go from, you know, east to west very easily Yeah, that ladder movement is important because I know there's a lot of companies that the letter one becomes easy And this is something we've helped is because of the flat network problem. They go well, it's behind the firewall So it's okay the way the 2003 server like no you need to segment that off to yet another one So your general users that don't need access to it Which is usually you're running it because you have some particular piece of software But that whole software net whole thing should all be in its own container that way if The general person in accounting clicks on something you don't get that ladder movement This is it still there's ways to protect against it So it is doom and gloom in terms of this particular bug We're talking about but if you have an overall security plan So we help prevent some of that, you know east-west movement your life's gonna be a lot better Exactly. I mean I've had customers that I've had ransomware events where one endpoint got ransom and I'm like Bravo, and they're like it by the way We got you know, I drive and we got these other ways for us to be able to look at when files get changed And we audit this and you know So and they still had things that they could have done better and can still do better And that's how they get to that next level of hardening where they're like, hey, we survived and What what our competitors may die from right? Yeah And so it validates the spin on security at that point and sometimes that's what it takes Is for you to go through a breach and actually see that the things that you're doing is are working, right? Like when Tom lets me on his network and I start pinging around and then he goes. Hey, I got our watch on So I see what you're doing and also I got I got tour blocks. So what was happening, right?  I'm like Forget Tom's rack. I want to go find Steve's computer because I know Steve has like some special VPN That'll let me do other stuff It is kind of fun and this is why you know so much of what I've talked about on my channel is a lot of that And Xavier talked about the other side the tooling side on his channel So I'll leave links where you can find out more about Xavier and his in his company things like that and of course links to the code red and the bottom line in If you're looking for what the immediate thing is patch and once you're done patching because if you don't even finish This video if you're not patched Get that done Once you're done with that start talking about security plans start putting some thoughts on it and segment your network and be safe Out there, man. It's a it's a scary world. So we're gonna get back to work Yes patching and uh, I got new hardware done. I'm playing with Yep. Yep. We got some new lab builds. So you're gonna be start seeing a lot more from Xavier Um, I'm help that's what me and him are gonna be back to and too is we have the I see all new servers And back there.

Urma, created by Cy Howard, transcribed from Hollywood, and starring Marie Wilson-Azerma and Kathy Lois as Jane. I went to the vegetable department and picked me out a nice, plump, solid head of cabbage. And then I'll take it home and put it on top of a broomstick, dress the whole thing up and then have a nice, intelligent conversation with it. I guarantee you that head of cabbage will make more sense than my roommate Irma Peterson. A million dollars before, but he always got Washington's picture on upside down. This is what he's making. Let me see that bottle. Right there. Drink, baby face. Mother nature's wonder youth restore. Yeah, and you see what it says? One sip and you hop and skip. Well, I got a feeling it should be one swallow when you're here today and gone tomorrow. No, Jane. I made this from the secret formula. Look at the ingredients. Let me see. Let me see. Baby face youth restore contains glopo, the vitamin extract of watermelon rind. And since you never saw a wrinkled watermelon, imagine what it'll do for your skin. Baby face is harmless and may be taken internally or out of doors. The ingredients and is approved by the Board of Health of Tibet. Oh, Jane, that's nothing. Here are some testimonials I'll have printed. Listen to this.  Oh, no. See those, will you? I have been using baby face for 62 years and now wish to sell my razor as I am too young to shave. This one, I was an old soldier who was about to fade away and I drank three bottles of baby face and I'm still here. Signed General Grinnick. You're hooked on this, are you? Of course I am. As an outsider to produce this stuff? Yes, he's already sold 15 bottles. And really, Jane, it's wonderful. I think I'll buy a bottle, too. Irma Peterson, don't you dare use that stuff. This isn't the first thing your boyfriend has tried to sell. You remember his famous magic dandruff remover? Well, it removed dandruff. And all the hair, too. I wasn't mature then, but now he's big business. Do you realize he will make 90 cents on every bottle he sells? How much is he selling it for? 85 cents. 85 cents and he's going to clear 90? Yes, there's all profit and he gets a nickel back on the bottle. We're going to make a fortune and we're going to get married. Secret path, kids. I'm Jamie, my two little hockey players.  Oh, perspective. So what, after six years, could you do better? Girls, do you have a little bit of confidence? Are you well, professor? No, I lost my head and ate the goulash at the Gypsy Tea Room. What's wrong with the goulash? It's all goo and no lash. We haven't seen it for a couple of days. Neither have I. You know, the last time I saw her was Sunday night at the fireman's ball. She was there a popular. Oh, God, you mean the men flocked around her? Oh, yes, she was wearing a red dress and they thought she was a fire hydrant. But truthfully, I felt sorry for her. Why? Every time the music started, she would drop a handkerchief and hope some gentleman will pick it up and ask her for the dance. Well? When the night was over, she had no dancers and a very sore back. So I volunteered to walk her home. Then she said, there's no sense kidding myself. She was no longer young and no longer attracted. Oh, gee, she's never said that before. I know, and as we stood on that street corner, I tried to make her feel good with flattery. I told her she was still young and still healthy. But then I almost ruined her. How? A cop heard me say, Kathleen, you are beautiful. And wanted to arrest me for being drunk. Yeah, I wish I knew where she was.  Oh, no. Don't tell me ahead about it, Professor. You look tired. Well, to tell the truth, I am, Jane. You know, I've been reading a book about psychiatry, and it's called Are You a Schizophrenic? Well, don't look at me. I'm Swedish. Jane, it's amazing the number of people who crack up under the tension of modern-day living. Yeah, the book must be fascinating. It is, and I'll tell you more about it as I read it. Well, goodbye, girls. Hey, and Professor, if you really feel tired and need a youth restore, I'll make you one that does wonders. It'll make a young man of you. Then I don't want it. I couldn't bear to see a young man spend the rest of his life in my room. Can I help you, madam? Is this the honest business bureau? Well, I'd like to register a complaint. What seems to be the trouble? I brought an item in good faith, and it turned out to be a fake. I want whoever makes this stuff put in jail where he belongs. I see. Your name, please. Kathleen O'Reilly. Now, what is the trade name of the product you bought and what proof do you have of it being fraudulent? It's called Baby Taste Magic Youth Restorer. So it's just experimented with a soy bottle, isn't it? A little? 15 bottles. I wanted to give it a fair trial, and for two days I've locked myself in my room. I've drunk it, I've rubbed it into my pores, I've even inhaled it. You can see for yourself. Well, I don't know how you looked before you tried it, but by the looks of you now, I would say you have a good chance of sending this person up for life. Well, that's what I want. Have you any idea who makes this stuff? No, but we'll find out, and you'll be our key witness after we make the arrest. You're done. Now, if you'll just sign this complaint. Oh, I'll be very glad to. Kathleen O'Reilly, single. That information isn't necessary. Well, it's not hurting anybody. A girl never knows who's going to read these things. Are you helping with me? Honey, it's ridiculous picking out furniture for a home just because, Al. Oh, not please, Jane. I know this time it's the real thing. I'll make a big fortune and marry me. Speaking of wonder, boy, here he comes down the street. Where? Oh, isn't it thrilling, Jane? Look at him. He walks like he's going someplace. Yes. Yes, and that fellow right behind him walks like he's going to take him there. Oh, gosh, Jane, I'm so proud of him. He's become so successful. Look at him talking to that man.  Probably shaking hands on a big deal. I don't think so. The other fellow's putting handcuffs on him. Who's taking him away? Chicken, I can't understand this. There must be some mistake, Chicken. Don't worry, I'll be back. Well, where? There won't be long anywhere from six months to five years depending on his good behavior. See you again. We missed you. Well, I've been staying pretty close to my room this last week. I've had a terrible experience. Where is Elmo? I understand she and Al are getting married. Well, she thought they were, but I don't know. Ah, there she is. And how sad to keep right to me. Oh, Mrs. O'Reilly, did you hear? Some horrible person made trouble for Al. Oh, that's a shame. Anyone who could do a thing like that must be of the lowest type, like the skunk who swindled me. Oh, someone swindled you? Yes, but never mind. What happened with Al? Oh, golly was doing so well in business selling his baby-faced magic youth restore. And then someone went ahead and had him put in jail. If I ever meet that person, the person who will ruin my head, troubles. Well, I sure do. Yes, Mrs. O'Reilly, who swindles you? Me? Oh, and I think someone wants to talk to me on the phone. I didn't hear the bell ring. They want me to keep it as secret. Sorry. Hello? Honest business mural? This is Kathleen O'Reilly. I filed a complaint about baby-faced youth restore and now I'd like to withdraw it. What do you mean I can't withdraw it? I must. I mean, the stuff really works, really. It made me young again. What? They send a man over to check for time. Four? All right, I'll be here and don't be late because I want to go to the playground and skip rope. The only day I just hope this works. Hello? Can you use customers? This is Mrs. O'Reilly. Do you have any kitty costumes? You do? What size do I wear? Well, I can't give the information over the phone. This is a party line. I'll be right down. Well, I said, Mrs. Peterson, I'll have nothing to do with it. So, Mr. Claude, I've worked for you for six years. Don't you think I deserve something? Yes, but the law won't allow me to do it. Three years ago, your boyfriend manufactured Professor Owl's strength capsules and you sold me a bottle. Well, didn't they give you strength? Oh, I never used them. I tried them out on our great days. We had to keep them in the house because the rabbit next door would beat him up every morning. You mentioned your boyfriend to me. Now, what I'm asking you to do is very simple.  Yes. Well, if you can find out who the woman is, I'd be good to drop the charge. Oh, all right.  Fortunately, I doubt if there's anything I can do, but, um, well... Hello. Honest Business Bureau, this is Milton J. Clyde, an attorney. Can you give me the name of the party who filed a complaint against baby face youth restore or it's against your policy? Well, uh, can you give me a general description? Uh-huh. Uh-huh. Mm-hmm. I see. She sounds like nothing would help her. Well, thank you. Goodbye. I tried nothing doing. Well, thanks ever so much for trying anyhow and as they say in the Navy, I'd like to give you an effort. Now, shall we get down to work? You're, uh... You're not too upset. Well, I don't know. Try me. All right. Take this letter to, uh, the Blue Star Store Company. My client has, uh, Justice Mr. Butler, the same man who has been with us since 1940.  There are more details to follow since early Mr. J. Clyde. Well, I guess I'm all right. I got it all. Good for you. Now, read it back, please. Uh, to the Blue Star Store Company. My client was in the room getting a little lovin' from the Butler. That's fine. They started to cut a rug, he flipped his lid, and he hasn't been safe. More details will follow.  Idiot! Mr. Clyde, don't you know it's not nice to call a lady named? Oh, I'm sorry. Mr. Peterson. Yeah?  And, Jamie, the amazing thing is this book on schizophrenia says that some of these people who crack up become other personalities to escape reality. Some of them think they are famous people, others think they are little children. Oh, that's very interesting. That's almost four o'clock. I think I'll go down have some tea with Mrs. O'Reilly. I talked to her an hour ago, and she seemed so tense. Jamie, do you mind if I go down with you? I don't know.  Come on, let's go. Well, what could happen to Mrs. O'Reilly? Mrs. O'Reilly, she's as steady as an old war horse. Only she looks like she lost the war. Believe me, after what I've been through today with Alan Irma, I don't... Oh, here's Mrs. O'Reilly. Do I knock? Mrs. O'Reilly, did you hear that? Yes. I've never heard her go around imitating a child. The way she sang was most unusual. I think the word is sickening. Maybe I ought to knock again. Go ahead. I'm going to look through that keyhole. Jamie. What do you see? Two old wrinkled bald heads. He's got company. No, no, no. My mistake. Those are needs. Yeah, yeah. She's wearing a little girl's dress. What? Yeah, yeah. And a curly wig. Oh, my goodness. What does she look like? Well, I can only describe her this way, Jamie. Centuries ago, among certain tribes, they used to... they used to do away with little girls. And this may revive the custom. Let me look, huh? Let me look. Oh. Well, it all fits, doesn't it? Just like the book says, tension, worry, escape from reality. Come to think of it, we haven't seen her for two days, and when we did, she seemed too nervous. Oh, Professor, you think it's too late? I don't know. Come away from the door. You know, a friend of mine teaches psychology. Let me see what time it is.  All right. Yeah, I was looking all over for you. Guess what? Please, Emma, not now, not now. But I just came from the honest business bureau, and at four o'clock, they're going to interview the woman who made the complaint against Al. Hey, Madame, please, be quiet. The tragedy has struck our lives. Well, what happened? Mrs. O'Reilly has lost her marbles. Mrs.  No, no, no, no, no, no, no, no, no crying. It's all fearless control, I tell you. But I remember her as she was. So let's go back 50 years. You know, it seems so terrible to read about these things, suddenly, suddenly it happened, like a bolt from the blue. O'Reilly, she was always so nice and kind. I think she'd do anything just so I'd be happy. Don't cry, honey. Don't cry.  Well, my dreams are greater than the two of you, because to me, she was like a grandmother. What are we going to do? Four o'clock. Four o'clock will tell the story. And in the meantime, let's try to be cheerful. Come on, everybody, everybody, relax. Dear man, before we go in, I can't tell you how grateful we all are that you could come by. I only hope I can be of some help in diagnosing her condition. I'm ten minutes early because my psychology lecture was shorter than usual. Shall we go in? Yes, yes. But don't reveal who I am. You see, it'll help my study if she wasn't aware that I was a world-famous psychologist.  If you had a Cadillac, we could tell her you're the plumber. I'll knock. Hello, hello, little Kathleen. This gentleman was in the building. Yes, yes, I know. I was expecting him. Expecting him? Typical manifestation. Dream world syndrome. Oh, how do you feel, Mrs. O'Reilly? Oh, fine, fine. Do you like my titty-desson machine, Bummit? Oh, it's lovely, dear. Would you want me to like to play hopscotch with you? Please, please, girl, just control yourself. Mrs. O'Reilly. Want to play post office? No, no, no, thanks. What I would like to know is, well, tell me all about yourself. Well, three days ago, I was a very old and tired woman. That's right. I saw her. Believe me, nobody was ever so old and so tired. But I've been getting younger and younger every hour since I started drinking babyface to my diffuse restorers. Babyface? Yes. Then I want this gentleman to go back to the honest business, you know, and tell him how wonderful babyface he really is. Honest business, girl. What's this all about? Aren't you the man from the honest business, girl? No. Lordy B, you must think I'm not... Yeah, but he's only got a quarter interest. We all think you're nice. So, Raleigh, we've been worried sick. You mean to say that you're the one who put in a complaint? Yes, but when I found out that the stuff was made by Alan, how much I was hurt in Irma, I got desperate. Oh, Mrs. Raleigh, you mean you were doing all this for me? Yes. Oh, I love you. And I knew the moment I walked in here there wasn't anything wrong with your mind. You look just as normal as I do. Oh, I think that... Oh, my goodness, give Mrs. Raleigh a leave. Why? I mean, I must convince him I looked younger than I was when I bought the youth drink store. Then I'll really be free. Uh-huh. Now I guess. Well, Mrs. Raleigh, you'll never fool anybody in that costume. Not as long as they can see your knees and face.  Do you think it'll work? Don't worry, I can convince anybody. Oh, that's right. Can't watch. All right, Irma, I'll go in the bedroom and I won't come out unless you call me. Glory be to sin, I'll get in the bedroom. I'm from the Honest Business Bureau. Oh, yes, I mean... You're expecting me? Yes, babyface says, wondering. You mean you're Mrs. Raleigh? Amazing, isn't it? How did it happen so suddenly? Hmm. Now that you see how it works, I guess you'll have to let out a go. I guess so. Oh, I'm so happy. You know it's wonderful when things turn out right. Yes, I guess so. I, um, I think I'll leave now. Oh, what's your hurry? Would you like to pee? No, I wouldn't mind. It looks worse every time I see it. That guy will get 50 years.

He was one of the part of telling me back She whispered to me that he would come to the hut as soon as he could Jungle wind tempered by the cool waters of the Atlantic chills the night air like great black silhouettes The giant trees loom out of the dark away in the distance the roar of new mother lion tells of a successful kill A live shadow we form detaches itself from the surrounding darkness a leap and she's opposed with unerring accuracy for me pray On the little platform in the trees Tarzan sits braiding his new grass rope while Jane watches You know, you're rather clever, right skin six months in the proper environment And no one would ever know that you grew up in the jungle Tarzan glances at Jane for a moment Then goes on with his rope making he has learned that some of Jane's remarks require no answer and to him This seems to be one of them. I wonder why Does it ever occur to you to think to wonder who your parents might be?

All the memories of his earlier life crowd in on him He thinks of Kayla his foster mother Kayla the she apes that had raised him and protected him against the tribe when he was too Little to fend for himself. He's all we thought of her as his mother and now For his driven forcibly home. He has no mother How's that looks at James? White skin Oh White skin Alone Jane has father Tarzan looks incredulously at Jane. There must be something wrong with his reasoning He's just learned so he thought that father was James word for male ape He turns over in his mind every possible solution Then he hits upon one that satisfies him father must be the name of one of the party He had seen at the hut. He turns toward Jane Jane father. Go hut. Yes, I did Jane father go hot No, fine. Jane Jane father go go many go. No fine Jane here.
