In this session, I will explain the framework that is used by the professional asset managers when they decide the combinations of risky and riskless assets to form a portfolio. So this particular framework is based upon the principle of the tradeoff between the expected rate of return and the risk. So we know that we are forcing in future that if we invest in a certain financial asset, we will be able to generate a certain rate of return. So based upon this information, we calculate the expected rate of return and then we also consider the values of the standard deviations of the expected rate of return in order to make a decision whether or not we are going to invest in that risky asset or riskless asset or if we want to go for a combination of the risky and the riskless assets in order to form a portfolio, then we are going to consider the tradeoff because we all know that higher return, if you want to take it through any investment, then you have to take a higher risk. So if you take a low risk, then obviously you will get a low return. So when we develop a portfolio or a professional asset manager, then we use this tradeoff as a framework. So in order to explain this particular concept or the framework which is used by the professional asset managers, I am going to take an example. So suppose you have 100,000 rupees which you want to invest and you have a choice that you want to put these 100,000 rupees in riskless asset or risky asset. So it is always safer and better to invest in multiple assets whose risk levels are different from that you can generate better expected returns in a safer way. So therefore, we just thought that we have choices, we have a risky asset and a riskless asset. Riskless assets are usually your T-bills, those who do not want to take a risk or a risk more than risk, they invest in tri-ribbles. You get very little return on that but your investment is secure, your money does not go to waste. But those types of investors who want to take a higher return have to take a higher risk. So we assume that the risk-free asset will give you 6% interest and the risk-free asset will give you 14% interest and the expected rate of return of 14% will be 0.14. So you can see that they have been riskless asset, which is 0.06 and the risk-free asset that you are investing in is 14% which can be written as 0.14 and these are the yearly values. So then we have to look at the standard deviation also because the risk-free asset is risk-involved. So you will not get this 14% return, expected rate of return of 14% will not be there. In this, there can be a shortage, we also have to make a standard deviation to make it less. So standard deviation means that on average, your mean return, expected return, on average how much variation or variability can come to your hand. So in this particular example, we assume that our standard deviation will fluctuate by 14% that is given by 0.2 and when we consider all this information, then there could be a question that according to this situation, how much money I am going to invest in the risk-free asset and how much money I am going to invest in the risk-less asset. So for that, we are going to discuss a framework which is used by professional asset managers. So I will be explaining that using different options, if you put your entire lakh rupees in the risk-free asset, then what will happen? If you put your entire lakh rupees in the risk-less asset, then what will happen and what would be the outcome, the expected rate of return if according to different combinations, you invest your investment in these two different assets. So I am going to explain this particular framework using this data which you can see in this table. So we have got multiple portfolios, you have portfolio F, G, H, I, and J. What is the difference between these? You can see that first of all, we have invested 1 lakh in the risk-free asset, we have accounted for them. Then in the risk-less asset, the amount of your 1 lakh per portion that you are investing, you have taken different options and defined these portfolios. Then we have expected rate of return and then we have accounted for the standard deviation. So these two things are going to play an important role when we have to decide. So let's look at the values in detail. So suppose, as a starting point, we have portfolio F in which we have invested 1 lakh in the risk-less asset. And by doing this, we have assumed that you will get 6% expected rate of return for which we use capital E, small r symbol. And I had told you that when we invest in risk-less asset, the standard deviation means the risk, the dispersion is zero. So you can see it is zero. Now if we invest, instead of 100% in the risk-less asset, we invest 75% of the total money which we have, i.e. 1 lakh per portion, we have put 75,000 in the risk-less asset and 25,000 in the risk-less asset. So in this case, you are getting 14% over 25% and you are getting 6% over 75%. So if you take the average of 6% and 14%, then your 8% expected rate of return has come out. If you define the variation in this, then we have discussed formulas of standard deviation. By using that, we have taken the value that is 0.05. So you can see that if we invest 75% in the risk-less asset and 25% of 1 lakh in the risk-less asset, then our return has increased by 0.02 or 2% but our risk has also increased. So if instead of 75, 25, if we invest 50% of the total investment amount in the risk-less asset and 50% in the risk-less assets, as a result, we will be able to earn or generate 10% expected rate of return with a risk of 0.10. And then similarly, if we increase the investment in the risky asset, we will be able to generate a higher expected rate of return but at the same time you can see that the risk has also gone up from 0.10 to 0.15. Now if we invest all the money in the risky asset and don't invest any money in the risk-less asset, then in this context, you can see 14% expected rate of return but at the same time the risk of standard deviation has gone to 0.2. So with this data set, we can see that as you go for a higher rate of expected rate of return, at the same time you have to see the rate of return and your risk is also increasing which we can see with the help of standard deviation. Now if we want to see this diagrammatically, then we can look at this particular risk-reward rate of line which is also known as the capital allocation line. We also call this risk-reward rate of line as the capital allocation line. Now what I have shown you is portfolios starting from FGH8JS. You saw that when we were investing all the money in our portfolio in risk-less asset, then we were earning 6% rate of return and our risk was 0. So with these portfolios, the expected rate of return and the standard deviation values are taken to these points and when you connect these points, you will get the risk-reward rate of line which is also known as the capital allocation line. When you have to draw the capital allocation line or the risk-reward rate of line graphically, then we always take the standard deviations on x-axis and the expected rate of return on the vertical axis. So in this way, you can see that through this line, we can represent the various combinations of risk-less assets with the help of graphically line in the form of different portfolios. So basically, when we are looking at the framework that is used by the professional asset managers, that is solely exclusively based upon the principle or the trade-off between the risk and the return. So whatever data we have used in developing or drawing the line which I have just shown you, which is called the expected rate of return and risk-rate-off line, or we also call it the capital allocation line that is developed based upon the information we have discussed in the table earlier. So you look at the various combinations of the total investment being invested in the different assets and then on the basis of that, what is then you calculate the possible expected rate of returns along with their standard deviation. So when you look at these values, the different portfolios with respect to the expected rate of return and the standard deviation values are when drawn in the graphical form, then you get the expected rate of return risk-rate-off line or the capital allocation line.


Okay, we're back live at Strata. We are in the afternoon program here at theCUBE, SiliconANGLE.tv's flagship telecast, where we go out to the top events and tech and explore and get the signal from the noise, extract that and share that with you. We're all about knowledge and pushing it out to the social streams. Thank you for watching. I'm here with Jeff Kelly, who's subbing in for Dave Vellante. He went to take a bio break because you know what, we go all day long. I take a break, Dave takes a break, but you know what? We go all as much as we can to get as much content as possible. And again, extract the signal from the noise and do independent quality analysis. And we're joined here with Virginia Carlson, who's from Chicago, Metropolitan Chicago Information Center. You guys are a nonprofit and you do a lot of work with data. So first, welcome to theCUBE. Thank you, thank you. And let's talk about data. So tell us your impressions of Strata and what's going on in the data world from your angle. Well, this is my second time at Strata. I was here last year and as I think a lot of people felt last year, it's so good to be together with a tribe where you can sit down and almost immediately get into a conversation about sort of universe versus sampling and everyone on the table understands what you're talking about. So it's fabulous to be here and it's meeting so many people from so many perspectives. And the tribe is growing too, right? And the tribe is growing and mainstream was seeing articles in the New York Times, Wall Street Journal talking about big data. We publish on Forbes at Silicon Angle. I have a, I'm a contributor on Forbes.com. They have a big data-driven section. O'Reilly also contributes there. Great group of people, but now the tribe is growing. Data is now a force. It's a business model. What's happening? I mean, what's old and what's new? Because there's all this talk about data, warehousing, business intelligence, same story, new wine, different bottle, kind of whatever the metaphor you want to use. But we're seeing new trends like predictive analytics and real time or whatever that means on whatever parsed definition. So what's your angle on this? Where are we? I'll talk a little bit about where we sit. MCIC, the Metropolitan Chicago Information Center, sits as a sort of funnel between big data and historical big data and the common good public good organizations on the ground that would have needed those data. They still need those data. For example, anything from a local American, Indian healthcare center that needs to understand where to open a new clinic to a larger philanthropic organization like the MacArthur Foundation who wants to know whether or not its local community efforts are making a difference. So we try to do what we call the data intermediary piece, curate the data, analyze it, visualize it, give them the findings. You know, the data, the tribe, I love the tribe analogy because that was obviously, Mark Pincus has failed startup with my friend Paul Martino and then now he's doing Zynga, big data company, but the tribe and this data world that we're living in, Jeff Hammerbacher from Cloudera when we was on the queue, talked about the Hadoop world because he was a baseball star. He said, data scientists are like gym rats. They're out there. They do it because they love it. So, you know, in the early days in this open data market, you got to go find data sources. So tell us from your perspective, because you have to go out and scour sources, find sources because that's the drug. You need source of data. So tell us, what's it like out there? How did you find sources? Are they rolling in now? Is there intermediaries? Are you brokering the data? Are you a data broker? How does someone get sources? And what's scrappiness you need? You need street smarts you need. The historical perspective, you know, we were founded 22 years ago to do 3,000 household survey projects every year because there wasn't enough data to do local planning and policy development. That went away in 2002 as more administrative and operational data became available from governments and as there was less, but worse response rates from surveys, basically. So, turning to open data and sources, at that point, 2002, you had to FOIA most of it. Now, there's the big open government movement and now, you know, sort of folks selling their souls, if you will, selling their private data to Facebook, Twitter, LinkedIn, and all the rest of that. So, from our perspective, big data is, I want to say a double-edged sword, but it may be a single-edged sword, and that as more and more data are collected by private sector companies, there is less available data for social service organizations that need public data to do public planning. So, are you saying there's data hoarding going on? Are people hoarding the data? Do they want to just control it? It should be a show called Data Hoarders. That's actually a good cable show. We should run that. Data hoarders, data hoarders. Facebook, you're hoarding data.  They need to monetize what they're doing is selling you back your own data in the form of services and advertisements, and that's how they're making money. But what it's doing is it's sort of choking. Choking, there's a good word. Other sources of data that people might use that might be more public, less confidential, and that drives things up for us. And the Open Gov movement in particular is all about getting operational and administrative data from the federal and local governments. And what I mean by that is how do we fix potholes and who are our lobbyists and all the rest of that? And what's being ignored is the federal statistical system, the Bureau of Labor Statistics, and the Census Bureau who have historically done the data, collected the data that local planning organizations need. Now, as- Are they making that available, or is it just locked in? It's just, it's the budgets being cut. As the federal government is moving towards open data initiatives and folks that are here are really working hard to get transparency from government, the federal government in particular is sort of saying, okay, that's where we're going. We're not going to be doing our statistical collections. So what's the trend line then? Is it positive, negative? I mean, is it going in the right direction? I'm trying to understand how the government is working here, because I'm not a big, again, self-confessed, I'm not a big guru on what's going on in Gov 2.0, whatever they call it these days. But to me, data should be available. It should be readily available. Are we seeing positive trends or negative trends relative to the government? Sounds negative to me. Well, there's different kinds of government data. And I think that difference has not been recognized by the open Gov movement itself. So it's positive on the one hand and negative on the other. It's positive for open Gov people, certainly, you know. From a visibility standpoint, rhetoric standpoint, the USA spending, all the rest of that, and all the rest of that. Golf clap, as they say, but you need the data, right? I mean, if... You need the data. There's calls for the data. We certainly have lots more at the municipal level as well as the federal level than we did 10 years. But what the Gov 2.0 folks don't understand is that there's been historical, statistical, what Census Director calls design data, collected for hundreds of years that's been used for local planning. And the more that the open Gov community pushes for transparency in administrative and operational data, the less the government is doing on the statistical side. And that's sort of, it's a geeky difference, but it's really important to the folks that we work with because if we don't have census data that tell us who is poor at the census track level, having access to who's lobbying the federal government is not doing us any good. So how does someone get involved? The average person who cares about this, because there are a lot of people who do care. There's a whole new generation of Americans, quite frankly, who, and people from non-Americans around the world, the global economy, don't want to have a data, with big data we can actually instrument society. So that's a good thing. So we talked about that on theCUBE last night. So how does someone get involved? Listener out there, reader, a watcher, a viewer of us, how do they get involved? Well, I think, you know, what drew, I'm sorry, Jake Porway and I are having a session tomorrow about and what I'd like the conversation we'd like to start and I would like to start is, okay, if so much data is being made private, confidential, folks are giving their data to Facebook, LinkedIn, Twitter, all the sort of big three, how can those data be used for social good? Target, big story in the New York Times. What if we could get that same target profile and help a federally qualified healthcare center target that woman and say, okay, here's where you need to go to get your prenatal care. For example, what if we could get Google search results on folks in different census tracts and what they're looking for as their vision is fading and use that to help the centers for, you know, guild for the blind, figure out what sorts of vision impairments are going on. So my column, the conversation that needs to happen is with privacy and confidentiality, how can we get the private sector data into the hands of local people trying to work on common good problems? Well, let's explore that a little bit. What responsibility do you think companies like Facebook have and how do we get to that point? How do we get them to companies like that to share that data, to make it available? What role do they have to play? What would your message be to them if they're watching right now? Well, my dream would be that they would see this as a philanthropic opportunity. There are other ways to do that. A number of them have sort of a philanthropic arm that will lend out their data scientists for problems, but I'd like to suggest to them that their data is just as valuable as the skills that data scientists have. And we should begin a conversation around how and in what under what conditions privacy and confidentiality can be preserved at the same time that they start thinking about sort of letting the data free. I mean, if data wants to be free, as they say, let's use it for public good. I don't, yeah. Virginia, thanks for coming inside theCUBE. We personally care about this society benefit.  The stuff that you're doing in your work is phenomenal. It's exactly the kind of use cases that the, I call commercial vendors don't necessarily talk, not in that business of actually helping human beings, but in the healthcare example and or doing planning around making society a better place, big data can completely streamline and make so much more operational efficiency around stuff that's already existing that data. So I personally believe in what you're doing. Thank you for sharing with us. Keep in touch with us. Let us know how we can get ahold of you because we want to promote your work and conversations. Good and bad. Well, we'd love to hear them all. Gov 2.0, to me, I think that's more of a rah-rah political stuff, but I want to see use cases like you're talking about where real applied data to really help people because the government's spending money to help people. Right, right. That's like the job, right? So like, you know, there's no, you know, if you can monitor that an instrument in real time, that's a good thing. So I'm for it. I don't know if that's a libertarian view or whatever. I don't know. I just like it. Thank you very much. Thank you. We'll be right back and we would not be able to bring this great constant if it wasn't for our ad-supported partners, Cloudera, MapR, Digital Reasoning, 1010 Data. Thank you very much to those vendors. Folks, watch the ads because those are the guys who would make it possible for us to bring this great content to you. Virginia's doing some great work. Thank you very much and we'll be right back.

Our scene opens on a wealthy, fashionable estate in Connecticut. A number of people are riding across the estate on horseback, but two of them have fallen behind, not realizing that they are both about to become participants in a tragedy. Better hurry, Audrey. The others are getting ahead of us. Herbert, wait. Let's walk the horses a bit. I want to talk to you, and this is the first chance I've had to see you alone all day. What's the matter, darling? You look concerned about something. I am concerned about your sister, Martha. Martha? Herbert, I... I don't think she wants you to marry me. What that sheer nonsense. Martha's very farmed of you.  Now Audrey, don't you think you're being oversensitive?  What's that? It sounds like one of our dogs. It is. It's Sultan, my sister's dog. There he is, Audrey, near that clearing. Come on, let's ride over there. What's the matter, boy? It's my sister, Martha, lying in the thicket. Hold my horse while I dismount, Audrey. What's happened to Herbert? Has she been hurt? Audrey, she's been struck on the head. Martha's dead.   Yes. Was your sister, Martha, part of the group who were on horseback? Yes, I thought she'd gone on ahead with the others. Well, hitting a horseback rider on the head with a club when you stand on the ground, that ain't an easy trick. Somebody on a horse must have followed the girl and struck her from the saddle. My partner, Mike Clancy, has a good point there, Mr. Langley. Tell me, were all your guests questioned by the local police? Yes, Mr. Keene, but none of them was held. They were all Martha's close friends and mine. It's unthinkable that any of them would have wanted to harm her in any way. In other words, you can't put the finger of suspicion on any of them. No, Mr. Keene. My sister, Martha, was a beautiful, intelligent woman. Very popular with men, though she never married. I loved her as much as I've ever loved anyone in this world, with the exception of Audrey, perhaps. Mr. Langley, tell me a little more about your fiance, Audrey Stafford. She's a wonderful girl. We met last summer on a cruise to Bermuda. She was on vacation at the time. She worked for a banking firm. But she resigned her position at my request shortly after we announced our engagement. I see. I'm wealthy. My late father left his entire estate to my sister Martha and to me. I didn't think it was necessary for my future wife to retain a job. What about that incident you mentioned when you told us the story before, Mr. Langley? What incident, Mr. Clancy? I imagine Mike is referring to your talk with your fiance, Audrey. Just before you found your sister's body, the talk concerning her unfriendly attitude toward Audrey. Oh, that... It was nothing. I shouldn't even have brought it up. Mr. Langley, I presume you came here to ask me to solve the mystery of your sister's murder. Yes, Mr. Keene. I came to plead with you to enter the case for Martha's sake. And also for Audrey's? What do you mean? What you told me, Mr. Langley, I imagine there is one suspect in this murder case. You mean my fiance? Yes.  But Audrey would never have murdered my sister for that, or for any reason. That still remains a question to be answered. However, I can't accept the case, Mr. Langley, unless you tell me everything openly and truthfully. I should have known better than to try to hide my real feelings from you, sir. Yes, I want Audrey protected. So far, no one knows that she quarreled with Martha before the murder. Over you? Yes, Mr. Keene. I overheard the argument. I said nothing to Audrey, thinking it would pass over after the wedding. Why did your sister want to stop the marriage, Mr. Langley? For a very silly reason. Martha thought Audrey wanted to marry me for my money. I never believed that, Mr. Keene, and I never will. At the same time, if I accept the case, you must be prepared to have me include your fiance as a possible suspect. I understand that, Mr. Keene, and I'm willing to meet those terms. All right. Now, how far is your estate from here? It's just over the line in Connecticut. Oh, excuse me. Mr. Keene's office, Mike Clancy speaking. Is Mr. Herbert Langley there, please? This is Mrs. Wrightson, his housekeeper. Just a minute. Your housekeeper, Mr. Langley. Oh, yes, I told her where I'd be in case there were any messages. It must be important. Well, here you are. Thank you, Mr. Clancy. Hello. Mr. Langley, this is Mrs. Wrightson. Yes. Mr. Ernest Porter's here to see you. He says it's very urgent, and he wants to know when you'll be home. Is he near the phone, Mrs. Wrightson? No, he's stepped out in the garden. Tell him I expect to be home within an hour. Mr. Porter didn't say what his business was, did he? No, sir, but he acted like it was a matter of life and death. All right, Mrs. Wrightson, I'm on my way. Goodbye. Goodbye, Mr. Langley. It's a neighbor of mine named Porter, Mr. Keene. He seems to have something terribly important to tell me. Who is he, Mr. Langley? He has an estate near mine. He and his nephew, Alan, come over quite often. I can't imagine what he's got in his mind, unless it refers to my sister Martha's murder. It probably does. And as soon as we find out just what it is, the better. Mike Clancy and I will go with you to your home right now. For just a moment, Mr. Keene, I have a key to the front door. Well, Mike, while I'm inside the house, I suppose you take a look around. You know the usual checkup. Right, sir. Come in, Mr. Keene. Oh, Mr. Langley, I didn't hear you. Come in. This is Mr. Keene, Mrs. Wrightson. Mrs. Wrightson, my housekeeper. I've heard of Mr. Keene, the great investigator. I'm very glad to know you, sir. How do you do, Mrs. Wrightson? Where's Mr. Porter? In the study. Oh, Mr. Keene and his partner, Mr. Clancy, will be staying overnight. Would you have one of the maids prepare a room? Of course, Mr. Langley. Oh, Miss Audrey called. She said she's coming out to see you at five o'clock. Well, it's almost that now. Sure, and when she arrives, please. Yes, sir. This way, Mr. Keene. Well, this is quite a handsome house you have here, Mr. Langley. It's been in the family for generations. Oh, here's Mr. Porter. Herbert, I want to speak to you alone. This is Mr. Keene, the famous investigator, Ernest. Mr. Keene? You mean he's taken over the investigation of your sister's murder? Yes. Well, then I suppose I ought to say what I have to say in front of him. I think you should, Mr. Porter, if it concerns the murder of Martha Langley. It does, Mr. Keene. Then what is it you want to tell us? Well, I have a nephew, Alan, of whom I'm very fond. He's been living with me since his parents died. And I'd stand behind him under any circumstances. What are you trying to say, Mr. Porter? Mr.  My nephew's innocent and completely honest. What are you driving at, Ernest? I think I know what Mr. Porter is trying to say, Mr. Langley. Apparently his nephew, Alan, is connected with your sister's murder in some way. And Mr. Porter is attempting to clear him, even before he's been accused. Mr. Keene, knowing you for what you are, a fair man, I don't mind putting my cards on the table. My nephew, Alan, came to me today and confessed that he was the first one to find Martha's body. You mean he found her there near the woods before I did? Apparently, Herbert. How did he happen to find Martha's body, Mr. Porter? Well, he dropped behind the rest of us as we were riding through the woods. The reason he said nothing about it up to now was that he didn't want to become involved, Mr. Keene. That's not a very good excuse. The boy was excited, frightened perhaps. At any rate, he admitted the truth to me. Yes, and it's in his favor. Mr. Porter's learning else you wanted to say to Mr. Langley? No. Except that he has my deepest sympathy. I appreciate that, Ernest. And thanks. In recent months, you and my sister Martha have become first friends, and I... I know you miss her as we all do. In recent months, did you say? Well, Mr. Keene, Martha Langley and I were better than friends. I dared to hope that she would marry me. I didn't know that. I said nothing, Herbert, because she turned me down. It was too bad both our families are rich and could have been a most advantageous marriage, as well as a happy one for me. I'm glad you brought that out by yourself, Mr. Porter. You mean if I'd hidden it, I, too, would have become a suspect? Well, Mr. Keene, as far as I could...  It was. It came from the back of your house. Both you gentlemen remain where you are. I'm going out to investigate. All right, young fella. Just stay where you are. What's happened, Mike? Mr. Keene, I heard this fella prowl around in the shrubbery, and when I yelled, he started to run. I fired two shots in the air to scare him. He stopped in a hurry. Who are you? Alan Porter's my name. I thought I was being attacked by a maniac. That's why I tried to run. You are Ernest Porter's nephew? Yes. Mr.  Take young Porter back to the house, Mike. I'll join you in just a minute. Okay, me buckle. Let's go. Good evening. Who are you? My name is Keene. Oh, the famous investigator. I'm Audrey Stafford. I'm glad you've come, Audrey. I wanted to ask you a few questions in regard to the murderer of Martha Langley. Leave her alone. I beg your pardon. Oh, it's you, Mrs. Wrightson. Please, Mrs. Wrightson, I can handle this alone. Audrey hasn't done anything, Mr. Keene. You have no right to question her. Aren't you taking a few liberties, considering that Mr. Langley asked me to investigate this case, and you're one of his employees? It's not meant as disrespect, Mr. Keene, but I've come to look on Miss Audrey as my future mistress, and I want to protect her. What makes you feel that she needs protection? You suspect her of being one of Miss Martha's enemies, don't you? I haven't mentioned that to anyone. Neither has Mr. Langley, I'm sure. Oh, then I made a mistake. I beg your pardon, Mr. Keene. However, you're not far from wrong. What? I do suspect Miss Audrey. Mr. Keene, you don't... You can't suspect Miss Audrey. She admitted to Herbert Langley that his sister, Martha, was against their marriage, and that alone could be construed as motive enough for murder... Don't say it, Mr. Keene. Don't say that. Mother! Please, Mother, don't... Audrey, did you say mother? She lied. I'm not her mother. That won't help, Mrs. Wrightson. It ties in with your strange desire to protect someone who should be almost as strange as you. So Audrey is your daughter. No one knew up to now. There are many more things that are still concealed in this murder case, Mrs. Wrightson, but I intend to bring them all to the surface, and at the same time bring Martha Langley's killer to justice. In just a moment, we'll return to Mr. Keene and the engaged girl murder case. Meanwhile, beware of unpleasing breath that breathes between the teeth. Use colonose toothpaste with dental floss action.

The murder of wealthy Martha Langley brings Mr. Keene the great investigator and his partner Mike Clancy to the fabulous Langley estate in Connecticut where Mr. Keene begins a difficult investigation. He has just discovered that Mrs. Wrightson, the Langley housekeeper, is actually the mother of Audrey Stafford, who is about to marry the victim's brother, Herbert. After learning of this startling revelation on the driveway in front of Herbert Langley's palatial home, Mr. Keene continues to question Mrs. Wrightson and Audrey in the hope of obtaining further information. Mrs. Wrightson, I advise you to be truthful with me. If you really want to protect your daughter, Audrey, as long as you know my secret, Mr. Keene, I'll tell you everything, but not in front of Audrey. You shouldn't have made me keep that secret, Mother. I wanted Herbert to know about it. Please, dear, let me speak to Mr. Keene alone for a few minutes. Very well, Mother. Audrey, you'll find your fiancee Herbert Langley in the house along with his neighbors, Mr. Porter and his nephew, Alan. I'll talk to you later, Mother. Yes, darling. Mr. Keene, there's one thing you must understand. My daughter, Audrey, is no snob. She pleaded desperately with me to allow her to tell Mr. Langley I was her mother. And why didn't you? I thought it would hurt her marriage, at least socially, since I'm Mr. Langley's housekeeper. I was so happy knowing she'd get those things in life I always dreamed she'd have. Wealth, social position and happiness. Go on, Mrs. Wrightson. It was easy to keep the secret as far as our names were concerned. I married twice. Audrey's name is Stafford, but I kept the name of my second husband, John Wrightson. I did it thinking that one day I might not want Audrey to admit that her mother was poor and ordinary. I wouldn't call your love for your daughter ordinary, Mrs. Wrightson. Her meeting with Herbert Langley was just a coincidence. I came here to work as his housekeeper after Audrey left on her cruise to Bermuda. And she didn't know about my new job until she got back. Then I cautioned her to say nothing about it to Mr. Langley. I see. Is there anything else you'd like to tell me, Mrs. Wrightson? Only that Herbert Langley wasn't the only millionaire who wanted to marry Audrey. Who else was there? Alan Porter. He was mad about her. And he's very rich, Mr. Keene, a well-known polo player. He wanted to marry Audrey too, but she loves Herbert. And Martha Langley, Alan Porter and his uncle altogether couldn't change that love. How do you mean, Mrs. Wrightson? Did they try to stop the marriage? Mr. Keene, two hours before Martha Langley's body was found, I happened to pass by the Chinese tea house. The Chinese tea house? It's a small cottage on the estate over there in the woods. Inside the tea house, Martha Langley, Mr. Porter and Alan were having a conversation. What were they saying, Mrs. Wrightson? Mr. Porter was saying that Audrey and his nephew Alan would make a good match. Martha Langley seemed to be irritated. She asked young Alan why he hadn't been able to win Audrey away from her brother. And what was Alan's answer? He didn't have time to answer, Mr. Keene. That moment, my daughter Audrey walked into the tea house, so they changed the conversation. It's very interesting, Mrs. Wrightson. It puts a new aspect on the case. What do you mean, Mr. Keene? I'll explain later. Meanwhile, would you please ask my partner, Mike Clancy, to meet me inside the Chinese tea house immediately and tell him it's very important. Mike! Is that you, Mr. Keene? I'm over here on the tea house porch. Sure, this is certainly a fancy shack, isn't it, boss? It looks like something from a Chinese palace. Mike, come inside for a moment. I want to show you something. Oh, look at this. Saints' preserves. Like someone must have tried to tear the house down, Mr. Keene. They're all right through the wall. The walls are flimsy, Mike, but they've been reinforced with short, narrow beams. That's the one part of this tea house that isn't authentically Chinese. One of those wooden beams, small but solid, has been pulled out right here. Mr. Keene, that missing piece of wood could have been the murder weapon. Exactly. And here's something else, Mike. Oh, it's a bit of cloth. I'm hanging on this nail head here where the beam was torn out. Now, if you wanted to tear a beam out of this wall with the aid of a chisel, say, how would you brace yourself? Well, I'd stick my nail up against the wall and this side for leverage. That's just what the killer did, Mike. But he unknowingly left this bit of cloth on the head of that nail. This bit of cloth comes from heavy writing breaches. So the killer probably never even scratched himself or herself. Herself? Well, nowadays women wear heavy writing breaches too, Mike. Well, Mr. Keene, that still leaves us with the job of picking out the killer. Several people were writing that day when Martha Langley was murdered. I know that. However, I think I have an idea. Tomorrow morning, Mike will all go writing here on the Langley estate and turn my murder theory into a fact. Maybe we're going through the woods. No, you better ride on ahead of us, Mr. Langley. My partner Mike Clancy and I will join you in a few minutes. All right, Mr. Keene. Come on, Audrey. Well, horses ain't exactly in my line, boss, but I try to keep up with you. You're right, but it will, Mike. Not half as good as you do. Hold up there, you old burner. Take it easy. That's when they were all pretty curious about why you wanted to take that ride this morning. My reason paid dividends, Mike. It did, boss. I know who murdered Martha Langley. All I need now is proof of how it was done. That's what... Here comes Alan Porter. Mr. Keene. Yes, Alan? I don't know why you suggested this ride, but I feel I owe you an explanation. A what? Last night, when Mr. Clancy fired at me, I wasn't prowling. Well, there's a natural mistake in all our parts, Alan, but you seem to take it more seriously than it warrants. Well, I just wanted you to know that I'm being honest and I have nothing to hide. I'll see you later, Mr. Keene. Sure, and he sounded like a young man with a guilty conscience, boss. You might have a very good reason for that, Mike. I found out last night after seeing a picture of the murdered girl Martha Langley and Audrey were the same height and often wore identical riding habits. What does that mean, sir? Alan realizes that I may know that Audrey refused his proposal of marriage and so may have wanted to take revenge. You mean that he may have killed the wrong girl because they looked alike in their riding clothes? Yes, it's possible. Mike, do you see that thicket over there under the apple tree? That's where Martha Langley's body was found. Seeing it gave me an idea. Here, let's get near the tree. All right, Mike, right here. Would you mind dismounting? It'll be a pleasure to get off this nag, boss. Oh, there! Oh! Mike, the printer ran away. We'll round him up later. Mike, the lowest branch of this tree is just a little above the head of a rider on horseback. Climb up there and I'll explain what I'm getting at. Then I'd do me best, boss. I'll go from riding horses to tree climbing. It's for his harvest. He'll be investigating businesses. He'll be spending with... Yes, good work, Mike. Now, unless I look up and peer very carefully through the branches, I wouldn't see you. Well then, Mr. King, the killer could swing from here in the tree and, as his victim came by on horseback, hit her on the head. Yes, Mike. I'm convinced that's the way it was done. But who was the murderer, boss? He seems to be joining us right now. Be quiet, Mike. Stay up there in the tree out of sight. Tired of riding with the others, Mr. Porter? What are you doing here, Mr. King? Solving a murder. That's why you decided to see what I was up to. What do you mean? The man I intend to arrest for Martha Langley's murder is you, Porter.  Very easily.  When you pulled your murder weapon, there wouldn't be amount of the tea house wall.  I saw it just before we left the house. Don't spur your horse, Keener.  That gun won't help, Porter. The others are riding half a mile away by now, and you seem to have lost your partner, too. I think this gun may help a great deal. Why did you kill Martha Langley? I don't mind telling you. You'll never get a chance to pass it on to anyone else. I killed Martha to protect myself, Keen. Protect yourself? How? Five years ago, my brother left $2 million to his son, Alan, and made me his guardian until he came of age. Alan comes of age tomorrow. He's 21. Did you steal his inheritance? No, I spent it. I knew how to enjoy it. I not only spent most of that money, but I left it in some of the most fashionable gambling houses in the world. And how did you think you'd get away with it when your nephew Alan became of age? It would have been simpler if it wasn't for Martha Langley. I was going to tell Alan his parents lost the money in those gambling houses, and that I kept it from him all these years just to save their reputation. But Martha Langley found out the truth? Yes. She made a deal, though. Said if I could get my nephew Alan to marry Audrey, she'd keep my secret and add $50,000 in the bargain. But you didn't succeed. No, that fool nephew of mine was crazy about Audrey, but she fell for her bit Langley. I think I know the rest, Potter. Do you? Martha Langley became angry when you couldn't fulfill your part of the bargain. It was her only hope of separating her brother from Audrey.  Away I'm killing you, Keen, right now! Look out, Potter! Good work, Mike. Wait a minute. I'll dismount. He's out called, Mr. Keen. When I hopped on his head from that branch, I fell right on top of him. He hit the ground first. Yes, Mike. Potter met justice on the same spot he committed his crime. He lured Martha Langley over here, when she became separated from the others. Probably by calling her as he crouched in the tree. And then he struck from above. Now he'll pay for his treachery in a court of law. So, Mr. Keen finds a solution to the engaged girl murder case.

What? So this is apparently the final skin for arcade mayhem. It's it's not Mangle like I think everyone was expecting it It's 8-bit Soakus baby Now this kind of messes with lore if you consider the fact that special delivery could be canon which Maybe but if it is then this messes it up real bad. It's got green eyes So clearly this is baby before Elizabeth possesses her before she scoops Elizabeth.  I don't know how they're gonna walk because this is Possibly the weirdest animatronic that we've ever got and keep in mind that this is not a skin of baby This is its own character. So I have no clue how they are going to walk But I'm interested to find out here we go. There she is. Oh, it even has the CPU, right? Because that's a it's own animatronic. So they actually do have a CPU. Okay 8-bit baby Nice that is great They are more. Oh 900. Okay. Thank God. Thank God I have enough I really want to know what they look like in the in the workshop Speaking of workshop. I have a few surprises Out of episode I managed to get Frostbear, no I had them before Chaco Bonnie and Somehow System Aero Bonnie and also Mangle So I have I used to have everyone well Everyone excluding the skins, but now there's 8-bit baby, which for some reason is not grouped in with baby Um That's weird. They're grouped in with the foxy's that that is extremely concerning. I need you anyways, okay? So let's us activate it 8-bit baby lure How are they going to work? That is the question if they don't utilize like the 8-bit cupcakes and the 8-bit characters That's gonna be a huge missed opportunity because it's a new animatronic which means it'll have its own Set of attacks its own footsteps its own stuff like that I am going to have to make a another FNAF a all sounds for 8-bit baby. God damn it But yeah, if you guys remember Frostbear, he was different from Freddy. He like throws the screen and He's all chilly. So I don't know what they can do with 8-bit baby Can you imagine we get like a scene when we defeat them of Elizabeth coming out? That'd be awesome But that's not gonna happen And while we're here, of course, we're gonna do multiple battles. So 8-bit baby here we go Look at that 400 tokens left over that is cutting it close. Oh Was that them was that them? Yes. Oh, they look so good already. Oh, they look so good already. I don't again I don't know how they're going to utilize the 8-bit feature I'm really interested and I have not seen anything about this by the way also babies difficult She's up there. She's up there for my for me for my for me. It goes mangle spring trap, baby It's gonna be tough it's gonna be tough it's gonna be very tough, but hopefully Listen guys, we've done three other videos on arcade mayhem all three of them. We have successfully defeated the characters I'm just getting rid of someone so baby can show up We have to continue the streak. I think one streak Let's see if we've done four so on streak 12 Okay, we're going for 16. I think This we have a lot of pressure And I have a feeling we're not gonna do it. Oh god. They're here Okay, here we go.  Oh My god Where is she Jesus they've got the music going to Actually is making it kind of difficult to hear the footsteps So I do kind of have to listen closely. Is it different? It sounds slightly different. Oh Jesus Wow Wow Well, I I'm I'm actually kind of speechless by the way God Okay, wait moving out this way Jesus that lag though Jesus That lag is insane. Oh my god, this is great What a way to hey, what a way to end the arcade mayhem event Out here. I don't know if that's lag or if the music is supposed to do that. Oh God start going over there That's so creepy music flash on a little bit Okay, not anymore. I don't like when they go on the green screen. Oh Jesus.  It's hard to tell. She's worse than baby. Oh Like I did not know where that was This is one of the best fights Actually, this is great. Oh Jesus, this is amazing. Stop. That's so creepy.  Oh, wait, I something popped up there. I swear No, I don't want to mod. I want the suit.  Oh Jesus. That was awesome. That was so good They Okay, I will admit they didn't do the cupcakes which is something I feel like they should have done maybe like mango Well, you have to collect the cupcakes but then again mangoes again like one of the hardest characters But also so is baby. So really what I wouldn't have mattered, but oh my god This was great. We still have three more rounds to do. That's one out of three. I mean four.  Oh my god. They I have no words that was again one of the best fights They change it so much that it really is one of the best experiences that I've had fighting anyone in this game Here we go again. That's such a great sound It glitches out that's so weird. Oh My god, hopefully that's intentional and that's not lag I'm sure it is intentional. Honestly Why? Right. Oh Jesus it doesn't lag a lot. That might be my phone Hopefully it is That wasn't lag. That was perfect.  Oh Hello Sorry Mike. Is that the same sound effects that Babe does when she dies in that minigame. I Don't think it is but it seems like it's close They nailed the voice to It's insane how they oh She flashes out for a moment. That's what it was. It's insane. How good an 8-bit figure is in like Literally a 3d game It's weird. All right, so here are the other two It's weird just shocking 8-bit baby and then seem them like move around and then explode into pixels That's cool. I got tired of waiting They're just so far away. It's gonna take them so long. So I just Just get them here already Changes the sound. Oh Oh No, is it glitching out, please? And not intentionally glitching out. I mean the camera.  No Quite literally the opposite Yeah, she doesn't make a noise when she charges and I think that's actually really difficult Because you can miss her easily. Hi.  Oh my god. That was So good Illumix this is this is amazing You'll be here. I know you are I'm sad we lost our Orc in mayhem streak, but you know what totally worth it. No, you can't I don't know if I hold my breath. Hey over here Are you moving too? Yes move away from the green screen. Thank you. You really like this area. You really haven't moved Hey, really? I can hear you talking and it allows me to identify exactly where you are It's actually really helpful You don't say it. Well when you stop talking, I don't know where you are But then you haywire and I know exactly what she is Oh Jesus over here. Okay. So the first round I was just abusing my batteries, but she's not that bad The round when I died was just Unfortunate. She's she's kind of like baby. Jesus. Don't do that over here somewhere. I think no, don't Oh Oh Hello If we didn't miss that one, we would have gotten all of them.  I I've been saying it one of the best fights that they have ever done Probably one of the best characters too I can't wait to get their cpu I would also love to see what they look like in the workshop. Actually, I'm gonna look on the reddit I'm sure someone someone has it. Hold on. Okay, someone's got it That's nice. Oh, they just like turn around. Oh, that's great. That is great That is a great workshop animation. I get it. They're limited to the 8-bit character, but for an 8-bit character That's pretty good Now to end it off I want to take a quick break and I I'm putting this at the end because I still want people to Hear about it But I also didn't really want to take it away from the the new update the final character in the arcade mayhem But I'm sure everyone knows by now Steel will studios the people who made fanat fjr and the people who are making security breach released a new game today and everyone Was so upset and so frustrated at them that they didn't upload A teaser trailer a teaser an update to fanat fjr They didn't do anything with fanat at all. They just released a new game. Um, and people are mad because not only Is it the anniversary for fanat fjr their first fanat game and The one that made a lot of money But it's just insane how mad people got people were disliking the video Hopefully and I looked on the steam workshop Um of the game to make sure no one left any bad reviews and thankfully no one has just yet But I want to say this and I think everyone knows this But there were just people out there who for some reason Just ignore that fact because they just want fanat content from steel wool Steel wool is not a fanat game studio A lumex is not a fanat game studio. Clickteam is not a fanat game studio They make their own games except a lumex seeing as Special delivery is their first game, but that still doesn't make them a fanat studio They make other games that make other content before fanat fjr Steel wool and clickteam made other games So don't get mad at them that they didn't release a teaser trailer or a new game the arculus port the xbox port a new update Whatever I was upset too But I realize that they do other stuff than fnaf It's really insane looking on the comments of their twitter post. I don't know if they made a reddit post I'm assuming they didn't because technically it's not fnaf, but their youtube video people are disliking it people You know were just leaving nasty comments and a lot of people on the fnaf subreddit have Mentioned this and have stated their own opinions which keep in mind are the exact same as mine And what should be everyone else's but for some reason people don't get it. So I'm saying it right now Yes, they make other games and no they did not release anything for fnaf unfortunate. Yes But don't let them It's crazy.  Anyways, that's the end of the video a great way to finish the arc in mayhem event Great fantastic. I can't wait to get this CPU. I can't wait to get this suit. It's gonna be it's gonna be very nice So thanks for watching. See you on the flip side. Goodbye


Hello y'all, what's up guys? This is Chris Pike. My friends come a big see back in action today. I'm gonna show you how to color correct I'm gonna try to do it real quickly using free tools. We're in hit film express This is a free video editor and all the things I'm going to show you are free So it's pretty wild. Let's take a look at what I got going on here on the left side I've got the original footage of this guy just walking in a forest you look at the footage the the trees and Like on the left side here. There's just no contrast. It's very dull and drab and it's just really boring footage Maybe it was filmed on a you know, not on a great camera or they didn't get the lighting correct There's a million reasons why you're not getting really nice looks But I've gone ahead and adjusted it here on the right side as you can see and now you can see that the greens are Vibrant the trees are nice and green. There's a huge Contrast between the green trees and the and the grayish pavement road here It looks a hundred times better and we're gonna do it using free Tools so let's go ahead and just start from scratch So I'm just gonna go ahead and delete what we got here in the timeline and we're gonna start from the beginning It's gonna go right-click and remove. Okay, step one You've got some footage drag and drop it into your media panel here. Secondly, just drag and drop it into video track one and Presto we've got some additional Footage in the timeline looking good looking good like I said though. It's not very pretty So we're gonna make it much much nicer now in hit film express you'll see the effects little window over here we're gonna go in and There are two things that we could generally look at there's color correction and then there's also color grading now This what we're doing is kind of color grading But when you go through color grading you're gonna see that the large majority of them are add-ons or their purchases So if I wanted to you look up do lots which are lookup tables Which is one of the ways I would normally do this you would have to purchase this and that's no fun Right. I want you to get good at this without having to pay money So let's go ahead into the color correction side of things and I was gonna show you a couple of quick ones And then I'm gonna show you just in case this works for you and then I'm gonna show you how to do it The right way, so if I drag auto color here the top one and I dropped it on to the footage You'll see here that it has done a pretty good job Just automatically it's not as good a job as we did or I'm about to do But for those of you that like to work fast and dirty and don't want to go through all of the Processes you can just go ahead and do that and you might get the right color So I just wanted you guys to be aware of that that auto color and auto levels these autos are pretty good But they're not quite there This is what auto levels gives us and you'll see that the reds in the on the side of the roads are coming out And the trees are a little bit greener, but it's not quite where I want it But anyways, you're now aware of this what we actually want to do though is we want to go down to hue saturation and lightness This is the one that works the best for these types of video and this type of footage Left click on hue saturation lightness drag it and drop it on top when you do that You're gonna see it does nothing, but it does open up the controls panel and when we go to controls Here's where we can start to make some differences I'm gonna open up the master here and now let's just take a look at what we got here If I do a hue shift, you'll see here how I am adding in a lot of green, right? And let's say let's go a little over the top just to show you the effect So this is the original on the left side This is the revised version the green the trees are much much more contrast either much more vibrant It looks great part of the problem though is the only real problem. This is this dude's backpack went from Blue to purple so we've got to make a few adjustments there So let's go ahead and look at the saturation as well So I'm gonna increase the saturation and see what's happening here. This is the original footage It has no saturation no color to it at all now. It is very saturated. Maybe even too saturated I don't know. Let's go ahead and dial that back a bit. Let's go with something like that Okay, so the hue so we've got a hue shift of about let's go somewhere around 64 Saturation we're overdoing it again, but let's go with something really big like 78 and then the lightness No, the lightness is pretty good They did it they filmed it during the day and they captured it good So there's no real reason to mess with that. Okay, so we're on our way, but we're not quite there We've got to make a couple more small adjustments I'm gonna open up the cyan and that's kind of like bluish, but it's like yeah kind of bluish. It's in there It's a nice cool color. We're gonna adjust the shift So watch what I do if I go all the way to the right kind of crazy But if I pull it to the left look what's happening. We're getting the blue back in there You see how his backpack sign are going back to blue and we're getting rid of that Super purpley look again. It's not perfect. I'm not saying this is perfect But by doing that what we've done is we've reduced the hue shift for only the cyan color And we can actually go ahead and adjust blue. Let's see if we want to keep shifted a bit Something like that. Okay, and then yeah, maybe magenta. Let's see the magenta the purple right take some of that purple out Let's say so on the left side We've got now if we close all of these and you guys this is for this Particular video your video whatever your footage is it might be completely different But I just wanted to show you the technique and very very quickly So by using this one effect hue saturation of lightness We've gone from this left side to this very nicely created right side And you guys can do that too by just going in and adjusting those values That's how you color correct for free using hit film express using only free tools only free software You're gonna be the best video editor, you know and it's gonna cost you nothing Thanks for watching this tutorial guys ton more stuff coming up. Stay tuned


Carlos Chagas discovered American tropanosomiasis, now known as Chagas disease, CD, in 1909. Since then, the disease has spread globally, becoming a major public health issue due to its high morbidity and mortality rates. The disease is caused by the protozoan tropanosoma cruzi, which is transmitted through the bite of triatamine bugs. Recent studies have shown that the disease can be found outside of its traditional endemic areas, including North America, Europe, and Asia. This suggests that the disease may be more widespread than previously thought. To combat the spread of the disease, researchers must focus on understanding the epidemiology of the disease, including the diversity of the parasites, vector species, and reservoirs. Additionally, efforts should be made to develop effective treatment prevention strategies.
