And now for the signal oil program, the Whistler. The mystery program that is unique among all mystery programs. Because you know who's guilty. You see his every move.  Yet the final curtain always brings a startling surprise. In the signal oil program, the Whistler. That whistle is your signal for the signal oil program, the Whistler. And I know many things for I walk by night. I know many strange tales hidden in the hearts of men and women who have stepped into the shadows. Yes, I know the nameless terrors of which they dare not speak. Yes friends, it's the Whistler for tops in entertainment. And for the tops in gasoline quality, it's signal. It takes extra quality, you know, to give you extra mileage. And signal is the famous go farther gasoline. So look for the signal circle sign in yellow and black that identifies friendly independent signal stations from Canada to Mexico. And now the Whistler's strange story. Uncle Ben's widow. From the veranda of the Crestview sanatorium, nestled high on the Mount Tamil Pice slope, Monica Dawson looked across the low rolling hills to the bay in San Francisco beyond. Presently the faint sound of a bicycle bell reached her ears. The sound of a dog barking. Moments later, the rider appeared along the narrow dirt roadway and then wheeled into the hospital grounds. Shielding her eyes from the sun, she peered through the haze, watched the dusty figure on the bicycle approach. And then suddenly she sat upright in her chair. There was something familiar about the man in the khaki trousers, the yellow t-shirt, the knitted cap.  Her head began to throb again. Minutes later, she heard his footsteps approaching and a cold wave of fear swept over her. Mrs. Kittridge? Yes? I-I am Amy Schlegel. Schlegel? I-I'm sorry, I don't seem to... Of course, you do not remember me. I-I was there on the road the night of your motor accident. It was-it was I who summoned help. I see.  Yes. Yes, I remember you were the man on the bicycle. That-that is right, Mrs. Kittridge. Tell me, how are you feeling? Much better, Mr.... Schlegel, Amy Schlegel. Wanted you to know I'm grateful for everything? Of course. I only wish I could have done more for your husband, I mean. There was nothing anyone could do. He died instantly. He was dead when I found him, yes. But then that was quite some time after the accident occurred. Mr. Schlegel? Yes? The accident occurred only a few minutes after we passed you on the road. I heard the crash and hurried to the place where your car had gone off the road. I-I could see your car at the bottom of the ditch. I, um, also heard voices. I'm afraid you must be mistaken, Mr. Schlegel. Oh, no. I heard voices. And I waited, Mr. Kittridge. Why, Mr. Schlegel? There is a saying, something comes to one who waits. May I sit down, Mrs. Kittridge? It's such a warm day, isn't it? Much warmer than... He knows, doesn't he, Monica? He knows what really happened the night your husband met his death.  But you're not listening. Your thoughts go back to that moment three weeks ago when it all began. Began with a flirtatious toast in the cocktail lounge of a fashionable hotel in downtown San Francisco. As you sat at the table admiring your reflection in a mirror, you noticed the man sitting at the table next to you. He, too, was admiring your reflection as he raised his cocktail, tipping it in a toasting fashion. You were instantly aware of his identity, and you decided it was time to go to work on this prosperous-looking gentleman. Hello. I'm sorry I had to use something quite so obvious as an excuse to get acquainted. It wasn't exactly original. A last desperate effort. I've been trying to attract your attention ever since you arrived. This is a hobby of yours? No, on the contrary. You're the first one I've ever seen in a cocktail lounge that I've cared to meet. I don't suppose you believe that. No. My name is Benjamin Kithrich. May I buy you another one of those, uh... Oh, perhaps you haven't had dinner. My name is Monica Dawson. You may buy me another one of those. Made up your mind about dessert, Monica? You know, you're a very persuasive man. A little while ago I let you buy me a drink, and here we are having dinner. The French pastry is excellent. Oh, sorry. I have to watch my figure, you know? Hmm, it's quite a... I'll, um, have it been a decade instead. Is this a vacation for you? Well, in a way, with Brad gone, I... I can have my little, uh, fling, so to speak. Brad? Oh, I haven't told you about Brad, have I? You see, I'm president of the Kithrich Steamship line, and Brad's my nephew. He's, uh, vice president. He does all the work, thank heaven. He's a whirlwind. All work, no play. Married to his job, all that sort of thing. Obviously, he doesn't endorse occasional relaxation. No, I'm afraid not. He sounds delightfully crew cut. Pork pie hat, tweeds, a pipe, a dalmatian named Boy. Where's he now? Working out in the gym? Hmm? No. No, he's, uh, doing a little troubleshooting at one of our foreign offices. He'll be back in two weeks. Then, uh, your vacation will come to an abrupt end? Ah, yes. And no time off for goodbyes, you know? Oh, now, Monica, I'm afraid I've given you a bad impression of Brad. Really, he's quite a lad. I'm terribly fond of him. He knows more about the shipping business than I do. Well, you'll love him. I'm sure I will, Ben. He sounds just my type. Well, don't worry, Monica. We have two weeks to have a lot of fun. A lot can happen in two weeks. Then, I'll drink to Ben. This was a wonderful idea, Monica. Wonderful. Haven't you ever taken a handsome ride through the park before, darling? Nope. Never occurred to me. Uh, Monica, the last two weeks with you have been wonderful. Do you realize our wonderful times are just about over? Your Brad will be back in a few days. Yes, yes. Have, uh, have you really been happy with me, honey? Of course, I have. Monica. Yes, darling? Monica, would you, would you marry me? Ben. Would you, Monica? Well, I, I don't know. We could start making plans right now. Be married the day Brad gets back. Would we have to wait for Brad? You mean you'll... Oh, money, money. I've loved you since the day we met. But I, I never dreamed you'd ever consider marrying me. Well, I haven't said yes, darling. Well, Brad will be home by the end of the week. He can be my best man. Why couldn't we get married right away and surprise him? Well, I, I don't know. He, he'd feel bad about it. I, I really should tell him first. You're afraid of Brad, aren't you? Oh, that isn't it at all, Monica. I just want to do the right thing.  Brad, we'd better get the whole thing, Ben. Brad probably wouldn't approve of me, anyway. Oh, look, Monica.  It's none of his business. You'd marry me even if he tried to stop you. You have nothing to say about it. I can make my own decisions. We're getting married right away. With the prologue of Uncle Ben's widow, the Signal Oil Company brings you another strange story by the Whistler. You know, when a manufacturer is enthusiastic about his own product, well, you just naturally expect that. But when users are enthusiastic, that's the real proof of the pudding, which explains why here at Signal Oil Company fall is our favorite time of the year. It's the time when folks who have been on vacation trips and have had a good chance to test their mileage write us about the results they've had with Signal, the famous Go Farther gasoline. For instance, Mr. E. R. Strobe of Los Angeles writes, I just completed a trip of almost 4,000 miles much of it mountain driving. And not only did my 47 Chevy take the tall ones in high, but I averaged 19 and one-third miles per gallon. No wonder Signal is called the Go Farther gasoline. Well, to Mr. Strobe and all the rest of you who have written in about your experiences with Signal products, we want to extend our sincere thanks. And to those of you who have not yet joined the ever-increasing family of Signal users, may I make this suggestion? Cry just a few tankfuls of Signal gasoline in your car that its honest performance and its good mileage prove to you what Signal users have long known. That to get the tops in gasoline quality, there are just two things to remember. One, it takes extra quality to go farther. And two, Signal is the famous Go Farther gasoline. And now back to the whistler. It was easy for you to make Ben Kittridge fall in love with you, wasn't it, Monica? It was like playing a dull game of charades with Ben never guessing that your only interest in him ended with a Kittridge fortune. Yes, it was all so easy to marry Ben. However, you're a little worried about Brad, aren't you? And that night as you sit across the table from Brad at a dinner party, Ben is giving an honor of his return. You wonder what Brad really thinks of his new aunt. How about another drink, Brad? Why not? This is a celebration, a double celebration. Order the drinks, will you, Uncle Ben? Monica and I are gonna have this dance. We are? Well, that is if Uncle Ben doesn't mind. Mind? Of course not. Run along, you two. Mind, mind, mind. Excuse us, will you please? You know, I was a little afraid when Ben and I went down to the pier to meet you this afternoon. Afraid? Why? Oh, I thought perhaps you wouldn't approve. Really? Well, it's gonna take me a little time to get used to the ideas being married. Been a bachelor all his life. I never thought he would marry, especially someone... Someone young enough to be his daughter? I was going to say someone as beautiful as you, Monica. Is it difficult for you to say that, Brad? No. You are quite beautiful, you know. And you approve of Uncle Ben's selection? Of course. Any reason why I shouldn't? Well, I suppose some people would think I married your uncle for his money. What's so funny, Brad? I don't see why people should think that, Monica. Uncle Ben has no money. Having a nice time, Monica? Wonderful, just wonderful. Where'd Brad wander off to? Oh, he ran into some friend of his. Over there at that table. What do you think of Brad? You've charmed him completely. But I'm afraid you won't have a chance to get better acquainted for a while. He's off on another trip to Central America in a few weeks. Then why didn't you tell me the Kiptritch steamship company was floundering? Floundering? Where did you get that idea? Brad? Well, he didn't say it that way exactly, but he did say you have no money. Darling, the steamship company is worth approximately $12 million. Brad was probably referring to my personal fortune, or I should say lack of it. Lack of it? What do you call $12 million? That money isn't mine. It's a fortune that's been handed down from one generation to the next in our family. I merely manipulate the money in the interest of the firm. But don't you have any money of your own? Very little. Oh, I get a salary with an occasional bonus. The stipulation in grandfather Kiptritch's will allows only a set amount to be paid out each year. Living expenses, upkeep of the family, home, so on. All profits go back into the business. Well, that's hardly a fair arrangement. Well, it isn't for any of us, except Brad. He's the last of the Kiptritches. Is that some kind of distinction? $12 million worth. He gets every cent of the inheritance. No strings attached. I see. So Brad gets it all. $12 million. He can have it. The money, the company, everything. Everything. What do I care? I have you money. Yes, and I have you. You've made a mistake, haven't you, Monica? Brad's the one you should have married. Yes, it was a bad mistake. During the weeks that follow, you manage to see quite a bit of Brad. And then one evening as you return from a dinner party in San Francisco with Ben, a tailor-made opportunity presents itself. Ben, must you drive so fast?  Don't see why you insisted on coming this way. It's a shortcut, Manny. When we reach the signal oil station at the bottom of the grade, we'll turn into the main highway. Well, be careful. There's a man on a bicycle up ahead. I see him. You almost hit him. Now, Manny, I know this road like my own pocket. Come on, give me a kiss, eh? Oh, stop it, Ben. Watch the road. Ben, watch where you're going. There's a curve ahead. Ben, look out! My back, Manny. My back. Can you crawl out of the car? No. No, I can't get out. Get help, Manny. All right, Ben, if I get this... Hey, Manny, get help. Get up on the road. Get up on the road. There's a car coming. You're just standing there. Please stop a car. I need help. Yes, Ben. I know you do.  It's been a long time you stand there, motionless, staring at your husband, pinned beneath the car, listening to him beg for help. Finally, he stops calling you. An icy hand closes around your heart, as the realization of what you've done sweeps over you.  Monica, how do you feel? Dickly slept the clock around. Ed, what am I doing here? You're at Crestview Sanatorium. They brought you here last night after the accident. You were pretty well shaken up, but everything's going to be all right, Monica. All you need is a little rest. Ben, where's Ben? Where is he, Brad? Where is he? He's dead. You play the part of a grief-stricken widow so well, don't you, Monica?  And now with Ben out of the way you're free to concentrate on Brad and the entire Kittridge fortune. It's easy to convince Brad that you need him to help ease the unhappy memory of your husband's sudden death. And he postpones his business trip to Central America. In the week that follows, Brad is a daily visitor and with each visit you become more and more certain he's falling in love with you. Yet there seems to be an invisible barrier between you. Brad's loyalty to the memory of Uncle Ben prevents him from telling you how he feels. And then one afternoon if Brad is pushing your wheelchair through the hospital grounds. Monica. Yes? I'll be leaving in a few days. The trip to Central America? Yes. Do you really have to go, Brad? I'm afraid so. I've put off the trip as long as I dare. How long will you be gone? Six months probably. I wish I didn't have to go, Monica. I'd much rather stay here with... Well, there... there are so many things to do here at the main office since Uncle Ben... Yes, I know. This is far enough, Brad. I think I'd like to walk a little now. Monica, do you think you should? Of course, I'm all right.  Give me your hand, Brad. All right, but Dr. Fenway won't like it if... Oh, Dr. Fenway. You see, I... Monica, what's the matter? Oh. There you are. All right, better. I felt a little dizzy. I was going to faint. Are you sure you're all right? Yes, of course. It's a good thing you caught me. I might have fallen. Why don't you sit down? No, I... I like this much better. Why? Why don't you, Brad? What? I know you want to. Why don't you kiss me? A moment later, you watch Brad as he turns and hurries away. You've finally broken through the barrier, haven't you, Monica? Yes. The rest of the way will be easy. But you haven't much time if Brad has to sail to Central America in a few days. As you continue your stroll, you plan your next move. And a quarter of an hour later, as you pass beneath the window of Dr. Fenway's office, you hear voices. No, what do you mean? Don't worry, Mr. Kittridge. I'll take care of everything. You understand how I feel about this, Doctor, but it's of what most importance that I sail for Central America. I have already made arrangements to leave tonight. I understand. Thank you, Doctor. You'll talk with her in the morning? Yes, I'll explain everything to her then. Though Brad has suddenly changed his mind, sailing tonight for Central America is running away from you, isn't he, Monica? After that tender little scene on the veranda, when he held you in his arms, kissed you, he's afraid to see you again, afraid because he's in love with Uncle Ben's widow. Quickly, you hurry back to the veranda, and as you do, a reckless plan begins to take shape in your mind. But then you'll have to be reckless if you want to trap Brad in the Kittridge fortune. Now, as you sit on the veranda, a few minutes after the arrival of the man on the bicycle, the man who has come to blackmail you, your confidence, your plan won't fail. But you'll have to take care of Mr. Schlegel first. Will you come to the point, Mr. Schlegel? The point? Oh, yes. You see, Mrs. Kittridge, I am an artist, a painter. I thought perhaps you would care to sit for a portrait. How? How much? You may not believe it, but I am considered a very fine painter. How much, Mr. Schlegel? $5,000. Well, then I also have some beautiful paintings, landscapes, beautiful landscapes. Perhaps you would like to buy a few. The price, I assure you, would be most reasonable. Mr. Schlegel, there are people coming out now. I can't talk to you. Later perhaps, this evening? No.  I don't have the money now. Maybe a week. Very well. We'll make all arrangements then. Good afternoon, Mrs. Kittridge. In a week we shall meet again. Yes. You will have the money then. I'll have the money, Mr. Schlegel. But you won't get a cent of it, Mr. Schlegel, not one cent. The Whistler will return in just a moment with a strange ending to tonight's story. But now, since the hot weather that we usually have at this season tends to make ordinary motor oils break down and cause carbon, wear and corrosion, I thought this would be a good time to tell you about an improved type motor oil specifically designed to protect your motor against these abuses. It's signal premium compounded motor oil, the finest lubricant ever offered by the makers of signal, the famous Go Farther gasoline. Naturally, signal premium compounded motor oil has 100% pure paraffin base, the finest money can buy. But in addition, signal premium contains scientific compounds that make it do what no regular oil could ever do. While you drive, these compounds are busy doing many jobs, such as washing out destructive carbon, gum and varnish, neutralizing the acids that corrode costly bearings, keeping the oil from losing its body or from excessive foaming. When you can now enjoy all these extra benefits, why be satisfied with lazy old fashioned oil for your modern streamlined car? For extra driving pleasure, longer life for your car, choose the improved type signal oil that does so much more than just lubricate. Stop at signal stations for signal premium compounded motor oil. Your guarantee of a sweeter running motor. And now back to the Whistler. Three days out of San Francisco, the freighter Isham Kittridge plowed through heavy seas, a few hundred miles off the coast of Central America. It was a simple matter, wasn't it, Monica? With your position as a member of the Kittridge clan to persuade Captain Driscoe to let you hide aboard. To surprise your beloved nephew Brad when the ship was several days out at sea. And now it's too late for Brad to do anything when he discovers you're on board. A few minutes later, you slip into his cabin to wait. You're not worried about Slagle anymore, are you, Monica? No. Once Brad is yours, completely yours, you know he'll stand by you.  A quarter of an hour goes by as you wait in Brad's cabin, and then you hear voices outside. Here to join me in a night, Captain Mr. Kittridge? Oh, thanks, Captain, but I think I'll turn in. By the way, I'm expecting an important radio ground where you instruct me when it arrives. All right, sir. Good night, Captain. Hello, Brad. Monica. Come on, darling. Don't act as though you've seen a ghost. Monica, you shouldn't be here. Why not? I think it's a splendid idea. I just couldn't stand that sanatorium another minute. You didn't see Dr. Fenway before you? Oh, we wouldn't have approved, I'm sure. Monica, why did you wait so long to let me know you were on board? Oh, I had to, darling. I had to wait till we were out far enough so you couldn't send me back. Now, we're miles at sea. Three days, at least, from the nearest port. It's too late for you to do anything. Yes. It's too late to do anything.  Be nice.  I just couldn't bear it if you weren't nice. Oh, Monica, you don't understand. The afternoon before I sailed, I had to talk with Dr. Fenway. He'd consulted a brain specialist about your case. The report had just come in. Brain? Brain specialist? Actually. Monica, your head was injured in the auto accident. The report confirmed Dr. Fenway's findings. Subduro hematoma. Hemorrhage of the brain. What? What does that mean? Brad? Answer me. They were planning an immediate operation. It would have cured you. But any delay, even a few days, means death. Let that whistle be your signal for the signal oil program, the Whistler, each Wednesday night at this same time. Brought to you by the Signal Oil Company, marketers of signal gasoline and motor oil and fine quality automotive accessories. Signal has asked me to remind you to get the most driving pleasure, drive at sensible speeds, be courteous, and obey traffic regulations. It may save a life, possibly your own. Featured in tonight's story were Betty Lou Gerson, Theodore Von Els, and Jeff Chandler. The Whistler was produced and directed by George W. Allen with story by Jim Lainer and music by Wilbur Hatch and was transmitted to our troops overseas by the Armed Forces Radio Service. Remember at this same time next Wednesday, another strange tale by The Whistler. Marvin Miller speaking. This is CBS, the Columbia Broadcasting System.


Great, great. I am Mark, yes. All right. Well hello there, Mark Risen-Hopkins here, coming at you once again live from Google Iow 2013. I am here with Jay Kim, who is the director of R&D for Apex and Apex Labs, and you guys have done something caught in my eye. I'm a big fan of augmented reality, been writing about it for quite a while since it was a dream and an iPhone. And so, when I saw what you guys had over here, I wanted to get a little bit more deeper dive. You've got some glasses, an immersive display, and all kinds of interesting applications. So, let's dive right in. What do you guys do and what's it for? So, Apex is a smart glasses software company that actually built something that we call the Terminator Vision for the Army. And that means that we had a military pair of glasses with an embedded camera, those within. And we're able to pick off faces in a crowd and if I'm seeing a bad guy, then it just shows the results of that bad guy, that identity, who he is, what he does, where he lives, just delivers it to you on your heads-up display. So, that's where we actually got started by delivering the software stack for military smart glasses systems. And we started transitioning some of that technology off to the commercial world. And we started targeting large businesses whose workforce is largely mobile and largely desk-less. So, people that don't traditionally have access to computers. So, the idea is that we're going to use our software development platform and link up with smart glasses hardware guys and the software integrators and working with them to provide a platform to deliver real-time information to smart glasses users. Say, for example, someone in healthcare, an EMT, who wants to get help from a doctor who's remote, is able to grab his camera feed and then push it out there. And at the same time, the doctor is able to give them step-by-step instructions as to how to treat a trauma patient, logistics, being able to use glasses and navigate through all of the different warehouses and I don't really know where the next item is. Well, guess what? Smart glasses tell me where they are. So, that's what we do as a company, but here at I.O., we were invited by YouTube to implement our hands-free computing paradigm, user interface, to interact with YouTube videos completely hands-free. So, that's what we've got to show here. So, can you just walk me through what we have on this setup and you obviously won't be able to see what I'm seeing, but you'll be able to, not directly, I've tried this once before, it's very interesting. It's hard to describe to someone who hasn't put something like this on, but you'll be able to see what I'm doing as I'm controlling the interface, right? So, this is actually my cheat screen where this shows exactly what you're going to see on the glasses. So, as far as the headset itself goes, we took the Epson Mavario BT100 transparent displays and we added sensors to make these glasses smart. We added a five megapixel camera. We added a microphone and we added a nine-axis motion sensor and what that allows my software to do is it allows the software to understand what you're looking at. It allows me to understand what you're hearing. It allows me to understand your orientation. So, let's get it tight on this, Kenny, if you can, because it really is an interesting device. It's bigger than the glass, obviously, but it does a lot more than the glass. So, it kind of shows the thickness of the, it's not that thick, really, the plastic portion. And, you know, it's stereoscopic, right? So, the exciting thing about this display as opposed to glass is that this allows you to, this allows me to have a canvas that's in your line of sight and I'm able to draw into both of your eyes, which means that I can do stereoscopic 3D content, for example, and I can do 3D overlays on top of real world. So, you know, fundamentally, it's a different way of visualizing content than a glass. Right. So, let's change devices. You hold my microphone for a second and you can kind of walk me through, because the hands-free interface is something that's interesting, too, is you don't speak out to it like you do with some of the, oops, lost the nose piece.  Yes, thank you.  A lot of use. Yeah, it's been used quite a bit today. You got it? Oh, I got it backwards, don't I? You got it backwards. You have to hold it just as you're putting it on and then it'll stay in place. All right, there you go. All right, there we go. All right. So, I'm watching a video here, thinking I have one. All right, so, let's actually have you double tap on the right side of the sessor twice. Okay. Yeah, right here? Yeah, double tap it. All right.  Oh, wow.  So, yeah, there you go. Wait for that red thing to... Okay, here, here you go. Okay, so now you've selected the video, and you can do playback controls also using your head.  Right. So, let's do that again to start the video playback.  Yeah. And then a little to the right and fast forwards. So, you're able to completely control all of your YouTube video completely hands-free. Yeah, it's very cool. And then to get out, again, double tap it. It's very responsive. I mean, you don't really have to... You only have to hear it once and you understand exactly how to use it. Yeah, it's an intuitive way of interacting with just transparent screen where you don't have access to a touchpad. So, yeah, we caught all that, Kenny, I hope. It's a fantastic little device. It's a lot of fun. So, like as you said, you're targeting the commercial workspace. What is the kind of... Is it just a softer target? What made you decide to do that instead of go after the consumer space? Well, we think that there's just a tremendous amount of value proposition that we're putting out to all of our big clients where return on investment of all of these people that are wearing glasses is an easier sell, frankly, than some of the consumers who tend to be a little less forgiving. If I'm able to go and prove that using smart glasses is going to be able to cut down on the number of accidents and situational awareness, increase worker safety, and also improve worker efficiency across all of the industries that I mentioned, logistics, field service industry, healthcare, then that's an easier sell for them to take the leap into the next wave of mobile technology. So, I can also envision kind of a big data angle this too as well, because right now in a lot of industrial applications, RFID is kind of the name of the game where sometimes it's QR tagging or things like this, but we're talking about a system where you could probably, I mean, you could easily scan across like a warehouse floor and acquire the data with the sensors and not only be able to acquire it and store it, but you'd be able to see it in real time, kind of what's available or what your inventory is or something like this. Yeah, something that smart glasses bring, that no other mobile devices bring today is access to real time data heads up and hands free. And that's the crux of our software is that we do so much of our algorithm and underlying research is being able to smartly detect the context of the smart glasses user. So RFID being one example, but taking QR codes, which are becoming more and more ubiquitous. My camera that's embedded into these smart glasses is able to go and pick off QR codes just discreetly in space. And just through that, without the user having moved a finger is able to know exactly where you are, exactly what you're looking at. And I can go and tell the user based on those actions and based on that contextual knowledge, whatever it is that user needs to know right then and there. So data entry becomes a much less arduous task potentially. So what are the sensors? Let's go down the list of all the sensors that you have available on the platform so we can kind of get a sense of what's possible or what may be possible with the system. Right, so our definition of the smart glasses requires at least three sensors to be worn on the head. And it has to be a camera, five megapixel camera that we have in this case. It can be any resolution, has a microphone, and then it has a motion tracker. It has an accelerometer, has a gyroscope, and has a magnetometer for compass.  And it's also able to tell me through the camera what it is that I'm looking at. Okay. And I guess you've got it hooked into an Android device. Are you able to use any of the Android sensors that are available on devices to couple that with the data you're acquiring through the goggles? Right, of course. So our software is smart enough to realize that Android devices themselves can be also used as a control device if we so chose. So being able to get access to sensor data, for example, GPS so that we're not carrying GPS twice, we couple it to the host device and the phone. Okay. And so I wanted to, because we talked earlier, and you mentioned, it's a platform. It's not necessarily a package or you're not interested in selling the hardware. And you definitely don't want to, even though you're targeting the commercial sector, limit this away from folks that want to hardware hack this up or add to or use it for personal reasons. So I guess the most interesting thing is for those types of hackers and developers in the audience, what is the release date? When can they play with what you've built? So our platform, which includes the client-side user interface and user experience, alongside some of the logic that's required for augmented reality and smart glasses, alongside the server-side logic that manages all of it and pushes real-time data is, we call it Skylight. And Skylight's going to be available at the end of August, running on a set of these BT100s and all of the sensors that power these glasses, we're also going to make available at that time as well. Fantastic. Well, I appreciate you taking the time today. This is a really cool thing. We're going to be watching you guys as you progress forward. As you say, you bet the company on it, so we're going to see if that bet pays off. Mark Russel Hopkins, Founding Editor at SiliconANGLE, we'll be back just shortly with more Google I.O. 2013 coverage. So keep tuned, right here, we'll be back.


Hey y'all, I'm super excited. I gotta do me something here. I gotta turn my lights on. It's kind of dark. All right, so we're gonna be talking about iFast in ketones. It's finally arrived. We're finally here. And it's just the beginning of us talking about it, but I'm excited about the end of this year. I'm excited about people starting next year. You know, with the world being upside down for the last three years, it's kind of fun because this is the opposite. Like anytime there's hard times, there's a huge opportunity, I guess, and the opportunity for us to take our own control of our health, our wellness, our vitality, our finances, whatever that might be for you. And so we get to launch something brand new that's never been done in the history of the world. Some of them that's groundbreaking, life-changing and truly transforming and we get to bring it to you. And I'm super excited that we get to do that. So let's have some fun. I'm just gonna kind of go a little overview with it all, have a little bit of fun and then we'll be doing more resumes throughout the week. But it's finally here that I fast with ketones. What we've known over the last seven years, and if you've been following me or if you've been just alive in this planet, Keto has gotten big, right? This Keto conversation. What's up, Kristen? How are you? So Keto has gotten, like, I'm just gonna tell you, 15 or 15, in 2015, when we launched, the word Keto wasn't even Googled. Like it didn't, the word Keto really didn't even exist. People did ketogenic diet or ketosis was, but the word Keto wasn't there. We created it. And it's went nuts for the last seven years. It's now becoming a global concept, a global understanding that, yes, being in ketosis is super important to elevate health, vitality, longevity, brain, all this good stuff, right? The results are extraordinary. But then we're like, how do we help people create a more sustainability and how do we maximize even further? And one of the things that we've been teaching for almost, you know, since we launched was fasting, but people tend to dread fasting. They tend to dread that, oh, I got a fast. I can't go without food. What's up, Crystal? I can't go without food. I don't wanna go that long. Okay, reading. Reading and talking at the same time, I'm not the best dad, but hey, I'm getting better. So really quick, if you don't mind in the chat, just hit me up. What fasting, what's the longest you went fasting? Do you like fasting?  What's up, Alicia? I did 14 days of fast. Now, I did my fast most because I felt crappy. I was really unhealthy. I was sick. I needed to get better, right? That's why I did it. I didn't have any kind of tools that we have today. What's up, Tyler? What's up? Yes, I hope you also had a merry, merry, merry Christmas to everybody out there. It was amazing. Tyler's done 60 plus hours, 24 hours. So that's great, you know? But what we know scientifically is that we can fast on a regular basis. It mimics what our ancestors would have done. And what we know that if you want to optimize human health and human potentials, we want to be as primitive as possible in the modern day world. As primitive as possible in the modern day world. That's what we want to accomplish. And so what we've done is we brought together the IFAST plus ketones, because there's a secret weapon within this five-day window of fasting. And it's not a five-day fast, so I'm clear, you're not fasting for five days. What you're doing is each day of the five days, you're going to go as long as you feel comfortable or as long as you want to fast. So you could go for a 16-hour fast, you could do it for a 24-hour fast, you could go a 36-hour fast, you could do a 12-hour fast, that doesn't matter. So what we're going to do is we're going to start to encourage you and teach you how to fast more comfortably. Never really fast it before. This is your shot, because it is such a huge health benefit to fast. Just so you know the research, and I knew this research probably back in 1999, it's when I first learned about this research. I'm big into anti-aging, I've been studying it a long time. I like human performance and anti-aging, they go together in the right way. And fasting has been notoriously shown to lengthen longevity more than anything else. So basically not eating you live longer. And I'm like, shoot, I like food too much. So I'm like, I don't want to not eat, but yet I want to live long. But living longer isn't being alive, living longer is like vitality. But ketones also have proven that they improve longevity and the quality of life and the quality of your overall health. So this is the exciting thing is now we have to bring them together. So the iFAST, what we're doing is we allow people to utilize tools, products like this and our other products. And you can take it while you fast, you get the same benefits and it magnifies the fast, but it makes the fast sustainable and enjoyable. So basically you get the benefits of what it's like to starve without starving.  Like that's what we are offering right now. It's unbelievable. I know it's kind of crowned.  And yes, I had a guy on TikTok that says fasting, not valid buddy, that is absolutely irrefutable valid. So I love it when people challenge me. You can challenge me all day long. I don't mind it though, but fasting has been proven to be one of the most effective tools to improve overall health. And so, but when you combine that with ketones, it changes everything, truly, truly changes everything. And that's what we've seen. If you've seen it over the last seven years, look at the stories that it's rolling in and rolling on. But also all the researchers and doctors have validated this for us. NASA scientists, top researchers in the world have validated this for us, which is really, really, really, really cool. So what we're doing though is we're launching this right now, we're in a beta phase. We've been playing with this package and this process for about five years more intently on implementing different fasting strategies with ketones. Now, this is the important part.  Therefore, fasting creates a struggle, though the drain fog, the lethargic, the feel like crap, the not moving very well.  So that's why fasting with ketones are so important because when you fast with ketones, what ends up happening is you get the fuel to your brain. You don't have the crash. And more importantly, when you come out of the fast, you don't binge eat as much. And so why we're liking the IFAST because it's five days long. We found a secret weapon in the five days, but you could go, like I said, you can kinda go 18 hours one day and 16 hours the next day and 24 hours the next day or eight hours the next day. It doesn't matter. That part doesn't matter. If we can create consistency and congruency, you start to transform your health. Your metabolic system activates and you get healthier and you became a very efficient human being and you live better, you feel better and you look a lot better, right? At the end of the day, we care about that too. So, but here's the coolest thing is for a limited time right now, I'm part of this whole process. So I just see you guys all know. We are putting together and we're offering our transformation guide, our fitness guide, and you're gonna get some of the most exclusive coaching from the top thought leaders in the world, medical doctors, top researcher doctors. You're gonna get the top coaches that have well over 100, 200 years of collective education, science and practitioners in the space to guide you and coach you along the way to provide a high level education. So it's just absolutely amazing that it's here.  We're all gonna do a big one at the end of January to kind of kick off the new year. But also what we wanna do is we really wanna provide the high level education that supports what we're doing. It's not just another fad, that we're past all that. One question I get often is what diet do I have to follow? And we're finally really gonna put a lot of more energy in this, like we are huge fan of elevating ketone levels and utilizing ketone supplementation. We are not saying that you have to do a ketone diet. I do a hybrid low carb diet, more of a paleo natural diet, but it's relatively low carb. I'm in ketosis with or without our product, but I'm therapeutically in ketosis with our product continuously. I have athletes, I have people that I work with that are on a standard American diet where they eat more carbohydrates. We have people that do a Mediterranean diet. We have vegans that are doing a vegan diet. We have people that are just trying to figure out should I even do, what should I do about dieting and what kind of food should I eat? And they're just getting started. It doesn't matter what diet you choose. It truly doesn't matter. It just matters that you start and that you know that you're gonna create a new lifestyle, whatever that looks like for you. Everybody has no idea what kind of lifestyle that, people always say it's not diet, it's a lifestyle, but what does that even mean? If you're 50 pounds overweight, the lifestyle that you start this week or this next month will not be the lifestyle that you live when you're 50 pounds down. So I want to be clear with that. Like we're not gonna give you a lifestyle.  Some people love like gelato when you go to Italy. That's my lifestyle. It's part of my lifestyle is to go to Italy and eat gelato, but I still wanna be fit, strong, healthy and play with my kids, so that makes sense, right? Now some people go, I just wanna drink beer and eat pizza all the time and that's my lifestyle. Well, then that lifestyle, you might be a little heavier, you might be a few pounds overweight, but doesn't mean you can't feel good with fasting and ketones, right? Hopefully it changes some of the behaviors and makes you desire better foods and you can maybe even get the benefits of both, right? So that's kind of the goal, maybe have pizza once a week and beer once a week. That'd be a better lifestyle if you're looking for longevity. Does that make sense? So that's what we're gonna teach you through this process, meet you where you're at. I'm TikTok, I know I'm getting people hitting me on TikTok. I'm gonna read it over here, it's small writing. Poor TikTok, I love you guys on TikTok, but I tell you what, I'm so into Instagram and Facebook that I always gotta like, I gotta TikTok too. If you wanna send me a message and you can't hit me personally, come over to Facebook or Instagram and hit me a message, I'll take care of you. At the age of 60 and lost 90 pounds, that is awesome way to go. Keep it up. Now hopefully at 60 years old, it's really important you maintain muscle mass. So we have a lot of people that lose a lot of weight, but if you don't maintain muscle mass and keep your metabolism up, guess what? You'll end up gaining that weight back and that's really important. That's why we teach the way we teach. So it's no more fads, I just gotta lose the weight. No, you have to improve the body, improve the mind, improve the health, improve the muscle system so that you can ultimately sustain the results as you're creating that lifestyle. And that is what we, that's what we do, that's what we create. All right, how many times a month can I do the IFAST? That's a great question. It kinda comes down to the individual person. The way it's formulated, remember we want people to eat real food, we want people to eat. So I would tell you, as long as you're providing a high quality food for yourself to provide energy, you could do two or three IFAS a month, if you want to. You can legitimate do it every day. But I wouldn't probably recommend that because that's not a, probably a sustainable lifestyle. That probably wouldn't fit into a normal, because it's, you're drinking utilizing tools, you're using ketones, you're using a mitoplex, it can become more, right? We're trying to teach people how to create a better relationship with food. So I usually recommend two to three times a month is a great way to get started for people that are maybe just trying to maintain, maybe they do it once a month. So that's something that people have to figure out. What's up, Eric? I haven't seen you in a long time. Y'all give Eric some love, give him a shout out. I want to study his, congratulations also on all the amazing things you have going. Is that Ian? What's up, Ian? I haven't talked to you in a long time either. It's been a long, been a minute. So really, really fun. So we have this new fasting protocol that's been released. It's being released right now with ketones and it's something that's pretty cutting edge. We've been working with, like I said, the top doctors that literally create formulations. They work with the most elite athletes in the world, the most elite performers in the world, all go to them, they do all their testing and that's what we've been working with on developing this as we're rolling it out to the world. Of course they played a huge role in rolling out ketones to the world with us. And it's exciting that we have to bring it all to you. I mean, we even have new trainers that are coming on board. I don't know if I'm allowed to say, maybe I can. But basically the most wealthy people on the planet is their trainer is coming on board and he's actually a whole friend of mine. I haven't talked to him in a few years but we got to reconnect actually just a few weeks ago and he will be coming on and doing some fitness coaching and perspectives and also some nutritional coaching perspectives. He's actually a celebrity trainer kind of guy. So you've seen on TV maybe a few times. So it's really cool that we're good to bring these people on and help bring some different wisdoms and perspectives for people that wanna participate in this program. So last thing I gotta go, it's eight o'clock, I gotta go, but one more thing I would say is this, remember this is that transformation, everybody's going through that at any time in their life. I'm going through a different transformation at 46. We just had a fourth child. I've had a hip replacement in July, two shoulder reconstructions over the last two years. I probably have to go back and clean this one up. I have an MRI this week. I clamped my shoulder one more time. And the reality is, is that we're going through, I have my own transformation, right? And when we think about transformation, I want you to think about like at the end of 2023, how do you want your life to be? Like if it's business or financial or health or whatever it is, but like create that, but start creating it now. Like I think so many people put on a goal and they just focus on that one goal, which is fine. You always have to have a benchmark to go after, but really what are you creating? And it's nothing's more frustrating for me, and I do this too by the way, I'm not perfect, but nothing's more frustrating when I work with people and they have a goal, but then at the end of the year they didn't maintain, they hit the goal and then they don't maintain it, right?  They're very different goals, right?  If you wanna run a marathon, run it, don't train very hard for it basically, and just go run the marathon because you'll wear yourself less out, right? But if you wanna be good at marathoning, then become a good runner. Like focus on becoming a better runner so that a marathon doesn't overwhelm or stress your body. The same thing with your life transformation, your health transformation, it's like at the end of the next year, what can you maintain? What can you create in this next year to maintain it? And so many people go, yeah, I did this diet and I stopped that, I went back to my old lifestyle.  That's not a new lifestyle. Your old lifestyle doesn't work for you. It didn't work for you. It's not a good one, right? But if you love where you're at and every element to your life, we'll still find a way to enhance it. How do you optimize it? Because you know in six years from now or five years from now, it's gonna change, right? It seems to be these hormones change, right? That's called wisdom, by the way, when you get older, you realize, you know, when I'm 60, it's gonna be different, right? When my kids are babies, it's different. I sleep way less now than I will probably in four years. At least I like to believe so. Or at least quality of sleep when you have a little one screaming in your ear. So the reality is, is that as you're looking out through this year and you wanna transform your life, it can look different anyways. We have another Olympic athlete we're working with and she's in a different phase of her career. She's in a different phase of her life and she's trying to optimize her performance, right? She's trying to get the most out of it. She's trying to create a new level for herself. That's no different than somebody that wants to lose 50 or 60 pounds, right? You have to come about it at the same approach, like, but you can't live the way you are today, right? If you wanna maintain a new life. If you wanna lose that 30 pounds and maintain that for the rest of your life and enjoy who you are and look good in a bathing suit, but yet go have some pizza, right? I'll be in the end of the year, I'll be out in Oregon. End of January, I'll be in Oregon, I think. Something like that. I'm going somewhere, but like I'm gonna have fun there. I'm not gonna follow a rigid diet. I'm gonna have some alcohol beverages. I'm gonna have probably some chips. Like, that's okay. Because I understand where I'm gonna end up in.

Well my dear students, the course is Labour Policy Pakistan and the topic in hand is National Labour Profile. National Labour Law Profile Islamic Republic of Pakistan. As you know that the concept of Pakistan was introduced in the 1930s. In 1940 the Muslim League led by Mohammad Ali Jinnah called for the creation of a separate Muslim state in the regions that housed a majority of Muslims. Eventually the independent sect 1947 provided for the partition of British India and the establishment of a separate self-governing dominion within the Commonwealth Pakistan. My dear students, these days Pakistan has a constitution of 1973, a permanent constitution of Pakistan. This is a permanent constitution of Pakistan and that became effective on 14 August 1973. The constitution of Pakistan provides for the federal democratic state based on Islamic principles of social justice. Point to be noted, social justice. The concern of the constitution is dispensation of social justice in Pakistan for the people of Pakistan. My dear students as you know that the executive power in Pakistan is vested in the president who is considered the head of the state. You would be delighted to know rather enlightened to know that the constitution of Pakistan contains provisions with regards to the labour rights and they are found in part two of the constitution. And part two relates with fundamental rights and principles of policy. My dear students, you will be enlightened to know that Article 11 prohibits all forms of slavery, forced labour and child labour. Article 7 prohibits rather goes to extent to protect the right of freedom of association and the right to form unions. Dear students, Article 18 prescribes right to enter upon any lawful profession or occupation and to conduct any lawful trade or business within the country. Article 25 is all about right to equality before the law and prohibition of discrimination on the grounds of sex alone. My dear students, it's a little ahead so we know that Article 37 E makes provision for securing just and humane condition of work. Ensuring that children and women are not employed in vacations unsuited to their age or sex and for maternity benefits for women in employment. Under the constitution, my dear students, labour is regarded as a concurrent subject. Labour rights fall, which means that it is the responsibility of both the federal and provincial governments to legislate on the issues of labour rights. Hope you have understood the topic. Thank you very much indeed.


I am Mrs. Sunita Dole, working as an assistant professor in the Computer Science and Engineering Department of the Vyalshan Institute of Technology, Sulapur. Topic covered here is Structured Query Language, Data Manipulation Language. Data Manipulation is Insertion of new information into database, Modification of information stored in the database, Deletion of information from the database and the Retrieval of information stored in the database. In this video, I am going to cover the Data Manipulation Language commands Update and Delete learning outcome. At the end of this session, students will be able to update and delete the data for given application using Update and Delete command. In previous video, I have covered the first DML command Insert, while in this video, I am going to cover the Data Manipulation Language command Update and Delete. Statement in SQL is used to update the data of an existing table in the database. We can update single column as well as multiple columns using Update statement as per our requirement. So here, I am going to cover the basic syntax of Update command, then updating the single column, updating multiple column and omitting where clause. The basic syntax of the Update command is Update table name set column 1 equals to value 1 comma column 2 equals to value 2 and so on where condition, where the set statement is used to set new values to the particular column and where clause is used to select the rows for which the columns are needed to be updated. If we have not used where clause, then the column in all rows will be updated. So the where clause is used to choose the particular rows. Now consider updating single column using Update command. For example, update the column name and set the value to Pratik Kumar in all the rows where city is Pune. SQL command is Update student set name equals to Pratik Kumar where city equals to Pune. This query will update first row of the table student and set the name Pratik Kumar for the city Pune as shown in table. Updating multiple columns using Update command. Example update the column name to Pratik Kumar and state to MP where row number is 1. Update student set name equals to Pratik Kumar comma state equals to MP where row number equals to 1. The above query will update two columns that is name and state in the first row and the table student will now look like as shown in the table student. Updating where clause. If we omit where clause from the update query then all of the rows will get updated. Example update student set name equals to Pratik Kumar. This query update the name to Pratik Kumar in all rows in the student table. Till now we consider updating the data in the table using data manipulation language Update command. Now pause this video and reflect on these questions for a minute or two minutes and write your response. Once you return the answer to these questions then you can restart playing this video. The question is which of the following options is or are correct about Update command. Questions are A. Update single column B. Update multiple column C. Both A and B. D. None of above. I hope all of you have completed this activity. So the question was which of the following option is or are correct about the Update command. As we can update single column as well as multiple column using Update statement as per our requirement. So the answer of this question is option C that is both A and B. The delete statement in SQL is used to delete existing record from a table. We can delete single record or multiple records depending on the condition we specify in the where clause. So in delete command I am going to cover the basic syntax, deleting single record, deleting multiple record and deleting all records. Basic syntax delete from table name where some condition. We can delete single as well as multiple records depending on the condition we provide in the where clause. If we omit the where clause then all of the records will be deleted and the table will be empty. Deleting single record using the delete command example. Delete the rows from the student table where city equals to Pune. SQL command is delete from student where city equals to Pune. The query will delete only the first row as shown in the student table after delete operation. Deleting multiple records using delete command. Example delete the rows from the table student where city is Sangly. SQL command is delete from student where city equals to Sangly. The query will delete two rows from the student table that are third row and the fourth row. Deleting all records example delete all the records of the table student. SQL command delete star from the student. All of the records in the table will be deleted. There are no records left to display. The table student will become empty. These are some references used to prepare this presentation. Thank you.


My uncle Lazlo was until recently, known as a quiet small town retiree. He collected stamps, watched documentaries, and was deeply involved with various local charities. I have nothing but fond memories of Uncle Lazlo. So when I heard he'd killed four people, I couldn't believe it. I'm sure some of you have heard of it, but from the other side of the media frenzy, an old man who snapped and killed his neighbors with a shovel. He would have killed more people if the police hadn't taken him down with deadly force. Something just made him snap. I was seeing everything from the outside as well. No one in my family knew what to say. There was no indication that Uncle Lazlo was so troubled. If anything, he was one of the saner members of my family. He had plans for years to come. I'd heard him talk about a trip around the world once he'd managed to sell off some of the stamps in his rare collection. Money doesn't add sand to your hourglass. He used to say he had no children of his own, so he spent a lot of time with his nieces and nephews. He always brought us amazing gifts for Christmas. So you can imagine my surprise when, just a few days after the murders, I received a letter from him, handwritten as always with a carefully placed stamp in the upper right corner, pristine condition with a picture of a blue sunflower. Tom Scog, Minnesota, it said, followed by the date 1912. Uncle Lazlo loved collecting various local rarities. And this one looked like a particularly old one. The letter itself was nothing out of the ordinary. He told me he was looking forward to seeing me on Thanksgiving and that he hoped everyone in the family were doing well. He seemed to be in good spirits. There was no indication of anything out of the ordinary. As the weeks passed, we were allowed to pick up his things. Mom couldn't bring herself to go anywhere near his things, so me and my two brothers were on our own. We took time off work to box up an entire life, mementos from various adventures, treasured keepsakes from his youth, pictures of smiling people that hinted at a life of optimism. I was the one supposed to pack up his stamp collection, years and years of meticulously collected squares, folders sorting them by dates, rarity, country, state, all kinds. Taking down the centerpiece of his collection, the CIA inverted stamp. That's what broke me. He'd shown it to me so many times, so proud that he'd preserved a piece of history. But it was when I started to clear out his desk that I noticed something strange. There among his stationery was an entire sheet of the blue sunflower stamp I'd received. I picked up the sheet, looked it over, and turned it around. One stamp missing, probably the one he sent to me. There on the back of the sheet, he'd written, not use. Two words, six letter, just not use. It was written with an orange highlighter, possibly the first thing he'd gotten his hands on. Looking around the floor, I found the highlighter thrown into a corner. I got this uneasy feeling that there was more to this and that these stamps were a part of it. I couldn't find much information about them online. Apparently they were the result of some sort of commission contest back in 1912. But that was all that was known about them. They were a bit of a rarity, but most collectors had just never heard of them. They were a local curio at best. I found a collector in the very town the stamps had come from, Tom Scog, Minnesota. I contacted them and was surprised to hear that they personally knew my late uncle Laszlo. They'd talked to him just a few weeks prior to the murders. They asked to meet me and to bring the stamps. Bringing the stamps seemed to be the most important part. How could I refuse? I took the family car up to Tom Scog, Minnesota over the weekend. I told my wife it was to meet an old friend of my uncles. It'd been a trying time for all of us. It'd be too hard to explain that there was a stamp collector that might know something about his nervous breakdown. By Friday night, I pulled up in front of a motel on the outskirts of the town. The second I got to my room, there was a knock on the door. There was a woman in her early fifties outside. She'd been running and she looked anxious. She had a frail physique and these thick glasses like something straight out of a cartoon. Even as I walked up to the door, she was still pounding on it. As I opened the door, she forced her way inside without even telling me her name. Do you have them? She asked, are they here? I nodded. I'd kept the stamp sheet in a folder and handed it over. She snatched it out of my hands. Okay. She said, her shoulder is relaxing. I have to go. Uh, I think I deserve some answers. I said, can you tell me anything about them? That's when I noticed she had a small blade in her hand. Just a pocket knife, but still, I'm just gonna walk away. She said, not breaking eye contact. Understand? I nodded. As she left, it took me a few seconds to accept I'd been robbed.  I called the local sheriff's office, but I didn't even get to file a report. As soon as I started explaining, the only thing they picked up was woman and motel, and that was all they needed to hear. They dismissed me entirely. I sat there in my room for at least two hours. I checked my phone and tried to get in touch with a collector at an emailing, but I got nothing. I started checking various social media for any indication of who my contact person could be. By chance, I found a subreddit for stamp collectors in a discussion where everyone said which state they were from. There was a user with the same name as the one who'd I'd been in contact with saying they were from Minnesota. It couldn't be a coincidence. I started checking their posting history and got a pretty good idea of who they were. Finally, I found a post titled the first thing I see when I get my morning coffee. It was a picture of the downtown area as taken from a hill. There were a few stores that I could use for orientation. Whoever my contact really was, they lived downtown. I took a walk and found the hardware store from the posted picture. During that, I managed to find a side road leading up through a forest path to a nearby hill. There was a long street with six almost identical houses, but I spotted a mailbox in the picture that seemed to stand out. It didn't take me long to find it. They'd actually painted a stamp frame around their name. How more obvious could you get? Walking up the graveled path to the front door, my heart was beating faster and faster. I felt like there was something awful around the corner, something in the air. Something had gone wrong. My fears were confirmed as I saw the front door wide open. I had to do something. I considered calling the sheriff's office again, but I figured they wouldn't take two calls from me the same night. I tried, but I was placed on hold. Instead, I armed myself with a shovel, leaving the phone on. I felt odd arming myself with something my uncle had been caught killing people with just a few weeks prior. I couldn't help but wonder what was going through his mind as he did it. I called out, but no one responded. Someone could be hurt. As I stepped through the door, I noticed broken glass on the floor. There was a broken wall sconce next to the kitchen doorway. There'd been a struggle. The kitchen was in disarray, the fridge was open, and two chairs had been knocked over. A few stamps floated in a puddle on the floor from melted ice cubes. There was a broken picture frame on the floor, showing an older couple smiling, next to what looked to be their grandson. I hung it back up on the wall. I don't know why it seemed like the right thing to do. I stepped back into the hall. I could see something on the floor in the living room, just a few steps away. But I had a bad feeling, so I stopped and listened. There was something outside. I clutched my shovel, but if it actually came to using it, I didn't know if I would suddenly I felt like a complete idiot. What was I even doing? Was it really this important for me to prove my late uncle wasn't the monster he was made out to be? I hesitated. As my pulse started to rise, I hid in the bathroom. Someone was coming. A pair of heavy boots stumbled through the front door. Someone was muttering to themselves, walking right past the bathroom door. There was a thump and a dragging noise, low rumbling, complaining. I considered bursting through the door, but I was paralyzed. I could barely breathe and my muscles weren't listening. A few minutes passed, then there was a second thump and another dragging noise. I fumbled my phone out of my pocket. I had to try and call the police again, and as soon as the other person left, I would. I couldn't risk them hearing me. They entered the house one more time, as if to check for something. Walking room by room, they started in the living room and made their way out. They were almost at the front door when they stopped. Come out. Something was flung across the kitchen, and the heavy boots started stopping around. If I was caught in the bathroom, I'd be cornered. I had to make room. I put my hand on the door knob, took a deep breath, and opened the door. I stepped out into the hallway and saw her. The woman from the motel dressed in heavy gardening boots and coveralls. She'd lost her glasses, and her eyes were going wild. They were twitching back and forth, seemingly changing size moment to moment. Her blue plastic gloves were covered in blood. She seemed taller. I backed into the living room. You. She growled.  I walked into the living room, keeping the distance. I heard my feet step into something squishy, maybe blood. I readied my shovel. Are they valuable? Is that it? Is that why you're doing this? I said, I could barely keep my breath up to speak. I was on the edge of just making a run for it. They're magical. She smiled, her voice both dark and shrieking at the same time. If you know how to use them. She made a lunge at me, and I almost slipped in the blood. I managed to bring down a bookcase between us, giving me some space. I broke a window next to me with a shovel. It was a bit of a drop, but I needed a backup plan. Something told me she wouldn't let me get out of this alive. I had to stay calm. Then she broke into a sprint. Using my shovel as a bat, I swung. It connected with the side of her rib cage, and it flung her across the floor. Something cracked. I didn't stop the check on her. I just climbed out the window. Before I even had one leg out, she was back up, though, and coming right at me. And then I noticed the side of her head was lined with blue sunflower stamps. She'd put them all on herself, the entire sheet. She tackled me, and we both fell out the window. That moment of weightlessness came to a swift end as we crashed into the damp backyard. My entire weight came down on her, and her left shoulder was twisted in an unnatural angle. Something snapped, and I rolled away. She didn't slow down, not for a moment. She gripped my shovel and just threw it aside. You can't just have one. She slurred. You need a bigger dose to stabilize it, to see. There was no reasoning with this woman, and it was just a matter of time before she caught up to me. I was panicking, my heart was racing, and I could hear her footsteps coming closer. She was grunning like a wild animal, getting ready for the kill. That deep rumbling noise in her throat made her sound like a bear. And then she flung me to the ground. She didn't blink. Her pupils were dividing like cells, only to float back together in a pulse. Her veins were turning black along her neck, and there was a hint of blue along the edge of her hairline. It opens your eyes. She whispered, you can see her marks everywhere. It's so comforting.  Something in my neck cracked, and all I could smell was dried blood and plastic. She pressed down, leaning her entire body weight onto me.  Thank you. She smiled. As I was losing consciousness, I heard screaming further down the path. Screaming, a barking dog, and a gunshot. And then I passed out. I awoke the next day in a hospital. My family were already there. I could barely breathe, and I could hear a wheezing noise coming from my neck. I couldn't even move my head. Thank God for rednecks and their dogs. No one knows who she was. She'd taken a bullet to the stomach, but just kept running. The dog had refused to attack her, and it curled up in a ball next to the path.  My neck had been crushed. I'm still in recovery, and my voice is just starting to come back. I've learned that the blue sunflower stamps had an adhesive made from the stems of blue sunflower, which was later discovered to be toxic. They used to grow all over that town, but nowadays they're pretty much extinct. There was a local pharmaceutical company in Tomskog called Hatchet Pharmaceuticals that helped produce the adhesive, but they just assumed that blue sunflowers were just like ordinary ones. I guess they were wrong. Needless to say, Hatchet Pharma aren't around anymore. I think Uncle Laszlo just wanted to use a cool stamp to send me a nice letter. He was poisoned, and it drove him mad. Strangely enough, there was nothing on his toxicology report to indicate some kind of altered state of mind, but I know for a fact he wouldn't do this just out of the madness of his heart. What that woman was raving on about? I don't know. No one knows who she was. All we know is that she was looking for those stamps, and she was ready to kill to get them. See there's more to that adhesive, the history of that entire event, and the town as a whole seems spotty at best. If anyone knows anything about the blue sunflower stamps or whatever happened to Hatchet Pharma, please let me know. I'm still looking for answers, even though my wife forbids it. And if you find any of the stamps in circulation, just don't use them.


I think one of the things that needs to happen, one of the things I still firmly believe in, personally, if we're gonna talk about centralized education, right? If I was running a country after grade 12, that's when everything was the same, right? The one thing I would introduce into their societies that would change society completely, for the better, for the better, right? If there was only one thing I could do right now, if they came up to me and say, Okay, Chico, you're allowed to introduce, change one thing in our society. Let's say, introduce one thing in our tour society that will improve our society in the long run, okay? I would make it mandatory, all right? That I couldn't end anything, right? I would make it mandatory that after grade 12, right, when people are graduating from high school, everybody has to go into one year of apprenticeship under a shaman consuming entheogens. Basically, for one year, they're going to be tripping balls, right? And they're going to be guided through the realm of entheogens. Personally, I would introduce it to them. Through Salvia Divinorum would be the first step. Boom. You kick them into the realm ASAP, shatter everything that they thought they knew, or everything that they have been brainwashed program with, right? And then you can basically delete the programming, reload it, right? And you don't need to do anything other than guide, let them load their own programming, right? All you need to do is have one year of someone sitting them, introducing them to entheogens and give them access to books, the internet, let them read different trip experiences, and let them choose which entheogens they want to explore for one year, right? You would get them to write a thesis, you would get them different. One year, that's what I would introduce into our societies. That will end things like 9-11, that would end wars, that would end the world on drugs, that would end our centralized indoctrination centers and introduce a new education regime where people can choose their own curriculum, right? It would roll something into existence that humanity needs.

I'm taking this with me again. Yeah, it's good. Thanks a lot. You're welcome. See you. What is your nickname on the jersey? I'm Boucher. Thanks a lot. Is it possible that I can use power from... What do you want to use? Power. What do you want? Yeah, I'm sorry. What's that? No, it's something. Yeah? Okay, good. The... Okay. The rest of the speakers. And this talk, so if there are any seats in the middle, can you please... Blah, blah, blah, blah. Blah, blah, blah. Blah, blah, blah. Blah, blah, blah. Blah, blah, blah. Blah, blah, blah. Blah, blah, blah. Blah, blah, blah. Excuse me. Can you move over towards the camera, please? No, no, no. That was last year. That was last year. Okay. This is a kernel subsystem. The kernel subsystem? Ok, I switch that. encode. Hey, good morning. about switch then. So first a little bit of history to set it up. So that's an Ethernet switch basically. Initially, an Ethernet switch was no more than what was called a bridge. Something deferred. Ethernet frames between basically two wires. You can't just connect two wires together. So you had something like something called a bridge, which was something like that to stretch the length of any Ethernet run. But of course, that was very limited. You can only connect two lines to a bridge. So therefore, multiple bridges started coming in. We're talking about like 34 years ago by the way. So multiple bridges, formerly known as a hub. You get a packet in on one port and it just flows it up to all the other ports. So hubs became very unpopular, very fast, because obviously they tended to just generate a lot of traffic where it didn't need to go. So in-came switches, whether switches, formerly as different to hubs, essentially they have an FDB, a forwarding database. It was learning and aging of Macs. That means it sees a packet come in on one port, an Ethernet packet, a frame, sorry. It remembers that the source Mac address came in on that port and therefore, if it ever gets a frame destined for that Mac address, it will send it out to that port. It will do that by storing that entry in the FDB, just Mac address that's the essential, that's the least of an FDB. Aging is an important part of that. We keep a timer and if it hasn't seen a packet from, is it five minutes? Okay. You see like five minutes left. Jesus God, what have I done? So if you see a packet come in, okay, you know that it belongs there from that port, but if it hasn't generated any traffic, you should age it out because maybe that host has moved to a different port, different segment of the network and therefore you should start flooding it again out of all the ports. So then what came in afterwards was VLANs. Very important. It's a way to segment your switches. Lots of ways to do VLANs, but you can do the VLAN priority tagging as codified in 802.1Q, the standard, where you can just do a partition switch where you don't have any extra tags on your ethernet frames, but basically you can figure your switch to be like two different switches, three different switches. And if you want to have forward traffic between those partitions, you actually have to connect the wire. So that's the basics of an ethernet switch, right? Now we've been able to do an ethernet switch or an emulation of it, you might say, in the kernel for a long time. But that was, of course, a software thing.   You put like four or whatever cards in your server. And you can configure a bridge, a software bridge. And it's got an FTB all implemented in the kernel. And you can look forward frames between them, things like that, and route them out to IP interfaces, things like that as needed. But of course there are some limitations there. First off, everything is done by CPU. So you need the actual general purpose CPU to do a bunch of comparing of frames, frame MAC addresses, looking up in the FTB. And it's not super efficient. Switches tend to be a lot more specialized. They have specialized memory, typically, for implementing an FTB that just makes it faster to do lookups. Another thing, of course, is these things tend to be IO bound. Initially, in early Linux, getting a frame on a NIC meant getting an interrupt on your CPU to interrupt would then cause the kernel to receive the frame from the NIC. But of course, too many interrupts kind of ruins your performance anyway. That was solved a long time ago. I forget what that's called. What was that system called? NEPI. That's it. That basically just handling more than one frame per interrupt. But of course, you've still got the same problem. As long as the kernel is doing all this manual work on a general purpose CPU, it's not going to be super performant. So then something interesting started happening. Little server routers and switches started coming out, starting with the venerable WRT54G and, of course, the WRT project came in. Now these are really kind of very specialized. They're small CPUs, but they have a built-in switch chip. That means they have typically something like five ethernet ports, and you can configure those to switch chips to actually do the switching between them. In other words, you program their FTB. You program the switches FTB so that if it gets a frame from one port, it could actually know, I'll just switch it through. I don't need to send that to the CPU. Of course, much more interesting, particularly on those little server routers where the CPU really isn't that strong. You can't really do CPU switching on those. So the WRT project needed a way to configure those switch chips in there. The problem, of course, was that you can't just use the vendor software. Vendor provided software or source code to program those chips because it's... Sorry. The problem is that those vendor software tended to be quite hacky. A lot of it was done in user space. That's one thing, but a lot of it was very much a hack. Programming a switch chip via some random SPI port or I2C port, nothing standardized about it at all. That was a real problem. What the open WRT folks found themselves doing was having to do real wildly different things to get the switch chips in different platforms. They came up with an abstraction, a switch configuration setup called SW ComFeed. It's basically a kernel framework and some user space tools to abstract out the programming of switch chips. It really got them ahead because there wasn't anything like that in the kernel at the time, the mainline kernel. So it was a big win for them. The features they needed to support tended to be kind of wild. I'm not sure what all was in there, but it was just random stuff that's supported by vendor switch chips. Some weird features sometimes. I'm not sure if SW ComFeed really supports them all. The problem with that was that SW ComFeed was never upstream to the mainline kernel. I'm not entirely sure if the open WRT product tried to upstream it, it was refused or if it didn't bother. Maybe somebody here knows if somebody is on the open WRT. That didn't show up. Next slide. It was somewhat tried. Hauke says that it was tried to upstream to the mainline kernel, but it was more or less refused because the kernel was starting to get something similar. That was the DSA sub-system. The DSA sub-system stands for distributed switch architecture, as I recall. It really comes from a feature present in Marvell, several switch chips, the MV88E series chips, which I think were originally the Intel switch chip division. I think Marvell just bought it. It was initially just for the way the Marvell chips worked, but actually it was pretty generic. You could do lots of other things with it. Some Broadcom and some Broadcom drivers were submitted for B53 series and the Starfighter 2, which I have no idea where it is, but apparently it's one of these small switch chips that you found at Salvo Radders. I see there's a Qualcomm after all switch supporter as well, the 8553, I believe, the 8000 series anyway. There's lots of room there, but the DSA sub-system, and this is very new, it exposes all the ports that it has access to the kernel. That means if you have a similar ladder running a mainline kernel with DSA-supported switch chip in it, and it has, say, five Ethernet ports, that means you get ETH0, ETH1, 2, 3, 4. So you get actual five ports. You can put different IP addresses on them, and just use them as a ladder. That way you can bridge them together as you like. If you bridge them together, the magic that happens there is it offloads the actual bridging to the hardware, and that's really important, right? Of course, that's what SWCoffee also did, but this is like it works in the kernel, sorry, it works in the kernel but towards user space, exposing the ports, but it does the actual switching if you configure it that way in hardware. So that's really important. The cool thing is the way you normally configure bridging with the VR control or the bridge tool or whatever, you just do it as usual with your interfaces as if there were nicks in your system, and just behind the scenes it all, the actual switching happens in hardware. That's really important, right? But the problem with the DSA is that it was intended to be MDIO only. I think that's because of the original Marvel thing, I don't know, but it was kind of limited in that way. There's lots of other ways to connect Ethernet switches to your system as many as there are buses, right? And there's enough buses. So then the switch-dev system came in. The switch-dev system is a proper kernel system. That means that you can invoke it from any bus. For example, you can have a switch-dev driver that is triggered by a device being present on a PCI bus or PCI Express bus. That makes it, of course, more interesting to, you know, the higher-end type of switch chips that need to kind of bandwidth that PCI Express uses. It's a very generic system, right? It's more generic than DSA. That means that DSA was essentially changed, the DSA's system was essentially changed in a kernel to be a switch-dev driver. So DSA is still there. There are still DSA drivers, but DSA, the framework itself, is essentially a switch-dev driver. If you want to do switching support for an MDIO-supported switch, the MDIO-connected switch, sorry, in the kernel right now, what you would do is you'd write a DSA driver, right? Because that's kind of the MDIO part of switch-dev. You might see it that way right now. It's kind of the easiest way, right? But switch-dev in general is super generic. It's got standard operations to work on your FDB. So add entries, edge entries, set aging time, and various other parameters. MDB as well, support. So multicast caching or group caching and things like that. VLANs as well, setting up VLANs. Let's switch that. The big news that this happened last year is that it was a while after switch-dev got merged before anything but DSA was supported. But at some point last year, Melanox, a vendor of very high-end switch chips, submitted drivers for their Switch X2 and then their Spectrum switch chips. These are super, super high-end, right? The Spectrum has a forwarding rate of 6.4 terabit per second. To give you some idea, that's basically you can have a 32-port switch. Every port, 100 gigabit, doing full duplex. On every port, constantly. And this thing can handle it. Right? You can use a switch with the Spectrum chip in it or the Switch X2 chip in it right now. Running a mainline kernel doing 100 gig on every port. 100 gigabit on every port. Just on a mainline kernel standard driver using the standard tools IPv2, bridge, all that stuff. That's magic, right? So what Melanox did is very much a pioneering thing. I think pretty much everybody in the network community and the kernel is hoping that other vendors will follow. Be nice if Broadcom would follow. Take a small miracle, but it might happen.  You might say somewhere in the spectrum between Melanox and Broadcom, there are a lot of other ones. Cavium seems kind of interesting. So we'll have to see what happens. Hopefully some more vendors will come in and ride drivers. If you want people to look at the Switch Dev subsystem, look at the kernel source. Include netSwitchDev.h. That's the entire API. It's super simple because it's so generic. I encourage you to take a look at it. So that's all I got. Any questions? 6.4, so it was for one node in detail with this number of 6.4 terabytes per second. Sorry, what do you mean? 6.4, the number is set because of the rich context. Oh, no, that's just the total switching capacity of the spectrum chip, the Melanox spectrum chip. The 6.4 terabit. I don't work for Melanox or anything. I don't mean to, you know, but I'm just saying that's a really high-end chip. It has a total switching capacity of 6.4 terabit. Do you have any questions? Do you have any questions? I don't know. I don't know. That's their marketing literature. I assume it's correct. I'm naive. I don't know. Any other questions? There's an exam after this. I don't have questions. Okay, thank you. No? Maybe. Or maybe it's just blinking slow battery. Yeah, I think it's all right. My sense? Are you kidding me? Are you kidding me? I didn't work in switching in the past. We were starting to do something. I worked for Intel, so we were starting to do something. I looked like a switch dad for the fulcrum stuff. It's good. So, you're using your own laptop, right? I have it on my laptop. I have it on my laptop. What do you call it?  No, that's a joke. That's a joke. No, this is the old one. They were probably my thing pad. They were probably my old bag. Your LinkedIn profile, I was stalking. And I saw you went to DCU, so I kind of assumed. That was my postcard. I was in UCG before that. You know what they say about assumptions? Make an answer to you and me. This is nice. You see this laser quick box? It's a Raspberry Pi inside. It's brilliant. You know, it's not picking it up. But it's not picking up my... It's not extending the display. Okay. Well, it worked for me. I don't know why. Maybe we could do it online with the USB key. Yeah, maybe that would be better. Oh, just with the... It's a bit strange, isn't it? I don't know. It was a funny one. Yeah. I say I exported as PDF, so... Exported from... PowerPoint. Okay, that'd be perfect. Okay, some USB key.  As people... Please, we can't have anybody in the stairwell, so if there are spare seats to the inside of you, please move in, so that we get as many people into the room as possible. And... If you can do that before he starts, that would be great. Could you switch? There's one particular row. I see five seats in the middle, and that would be really nice if you could lock those up. And there's four in the middle here. So, excuse me. Can you move that way? Thank you. Thank you very much. Next up, Ray Kensler, presenting PLDK, a TCP IP stack on top of DPDK and USB keys. Can you switch me on? Can I switch you on? I hope you can. I don't think people...
