suspense, and the producer of radios, outstanding theatre of thrills, the master of mystery and adventure, William M. Robeson. One of the axioms of drama might be summed up in the words, don't cheat the audience. Yet one of the most famous short stories of the century, the lady of the tiger, does just that. No, we are not about to bring you that famous masterpiece, but the story we are going to tell, in addition to being well-calculated to keep you in suspense, is also guaranteed to start a lot of arguments, none of which we hope will become too serious. Frankly, we don't know whether Sophronia Winters or Hiram Johnson is telling the truth, and whether one or both of them are crazy, but there's one point at which we can all agree, Sophronia's diary makes mighty thrilling reading. Listen, listen then, as Miss Moussides or Cambridge stars in The Diary of Sophronia Winters, which begins in just a moment. Another visit with Joe and Daphne Forsythe. Hey honey, I'm home. Daphne. Drop dead. Uh-oh, what's the matter honey?  Don Juan? Daphne, I'm no Don Juan. No, no how about S'Punol? Very funny, hahaha! Well, it was no prize, one sharpeit.  I've often wondered what's a lethario? I don't know, but that's what the wives on TV always call their husbands, I guess it applies. You want me to go out and come in again? As far as I'm concerned, you can go for a long walk. Preferably, on a short pier. Well, come on, Daphne, what's wrong?  Which beans? He said, quote, tell Joey he was right about those blondes. They're great, unquote. Blondes? That's what he said. Well... He didn't say blondes. He said blondes. Savings blondes. What? Sure. I buy them on the payroll savings plan. And I told Harry he ought to do it too. Savings blondes have a guaranteed interest that pays back $4 for every three. Which is a pretty good investment. That's a pretty good story too. It's true, so help me. That's why Harry's so happy. Savings blondes are great. Well... Maybe you're right. You would really fool around with blondes, would you? You're too fateful and sweet. Kind and... Fast talking. And now... Diary of Sophronia Winters starring Mercedes-McCainbridge. A tale well calculated to keep you in... Suspense. February 1st, St. Petersburg, Florida. I, Sophronia Winters, have hereby begun this diary. Because on this date I feel... For the first time in my 60 years... That I have begun to live. It happened this morning. I had just settled myself on the beach... When I noticed a man... A thrilling looking man... Strolling toward me. Well, uh, sitting out here all by yourself? Well, yes. Yes, I am. Didn't I see you last night over at the Starfish Tea Room? The Starfish Tea Room? Oh, yes. Yes, I was there yesterday. Oh, I said it might be a good table over there. Mind if I sit down beside you? Not at all. Oh, just a minute. Sit on this magazine. This sand sticks to your clothes. Oh, sand, don't bother me. Johnson's name, Hiram Johnson, comes from Green Harbor, Maine, on a big hotel up there, Summers. That's my whole history in a nutshell. My name is Sophronia. Sophronia Winters. Sophronia? You know that's quite co-incidence. My sister-in-law's name is Sophronia. Sophronia Johnson. You ever heard of her?  Sophronia Johnson? No, I'm afraid I haven't. Who was she, someone very famous?  No, Sophronia wasn't very famous up in the state of Maine for a while, some time back. Well, look what that sun climbed to. I'd say it was close to lunchtime and I'm going on a hunger strike unless you have lunch with me. Oh. Dear, dear diary, now I know what they mean by the young in heart. There is indeed a boy for every girl in the world and I have found mine. He is so kind and so generous and so strong and I am so weak because I want to be. Oh, what's the good of waiting, Sophronia? I gotta be back to the hotel in a week. We may never see each other again. Oh, Hiram, don't say that. I couldn't bear it. Then let's do it right away, tomorrow. There's a person out on Coral Avenue who will do the job first and we can take a nice moonlight drive out the alligator farm afterwards and have a nice short dinner. Then climb on board the orange boss and tomorrow night for Maine. Oh, but what would your family think? Wouldn't they be shocked? Family's all dead, I'm my own boss. Now just be the two of us alone together. The two of us. Alone. Together. The two of us alone together. But, dear diary, not exactly as I had imagined it, our wedding trip north on the Orange Blossom Express was all that I could have dreamed of. But now, now we are at the end of the journey, looming in front of us in the deepening winter twilight is a huge resort hotel, Hyrum's Hotel. It's wide baranda empty. It's ancient cupolas menacing against the grey sky. And not a single light burning at any of its hundreds of windows. What are you locking the gate for, Hyrum? Why not? Nobody coming in after us or going out again for a while. But I thought you said the hotel. The hotel is empty. Hyrum. Well, what is it now? Hyrum, darling, I know it sounds silly, but let's not go in there tonight. It's so dark and empty. Let's wait until morning. Let's stay in the village just for tonight. We'll stay in here. Now, get inside. Oh, my arm, Hyrum. You remember me telling you down in Florida about my sister-in-law, Saphonia? Yes. Well, that's her. That painting there on the wall. Now, you take a look at her. Good look. But why? She was a murderer. She was hanged in Portland 25 years ago for the murder of my brother, Hyrum. He earned the lobby of this hotel.  That's why her axe hanging over there on the wall. Oh, horrible. Yeah. Now, you stand over there under that painting. Hyrum, I... Get over there. Hyrum, please, you're hurting me. Now, you stand there quietly. Now, you remember I said you resembled my dead sister-in-law? Well, you do.  You were the second act of... suspense. In what form can an act of military heroism be acknowledged? In one example, the form is a rectangular blue ribbon set in a gold-colored metal frame of laurel leaves worn centered over the right breast pocket of the uniform. A bronze oak leaf cluster may be affixed to the ribbon for each subsequent award of the same decoration. This is the emblem of the distinguished unit citation awarded to units of our armed forces and those of our allies for extraordinary heroism in action against an armed enemy. One of America's newer military decorations, it is designated to recognize activity on or after December 7, 1941. The distinguished unit campaign streamer is blue with the name of the cited action embroidered in white. To be eligible for this citation, the degree of heroism required is the same as that which, in an individual, would warrant the presentation of our second highest award for valor, the Distinguished Service Cross. The distinguished unit emblem may be worn permanently by all those involved in the cited action, but for those individuals joining the unit later, the emblem may be worn only for the duration of their assignment. Both as individuals and as members of military units, America's servicemen have proved themselves worthy of medals and worthy of admiration by their countrymen. And now, starting Mercedes McCambridge, packed to love the diary of Sophronia Winters. I cannot understand it, and my heart is heavy. The hotel is deserted, unchanged and apparently uninhabited for 25 years. Wash bowls and pictures still stand in the empty rooms covered with cobwebs. The great dining room with its oak woodwork is alive with rats, and a row of broken rocking chairs on the front porch faces emptyly out to sea. Does he mean this to be my home? And now, Madea, let me show you the grounds. Oh, but it's dark. I want to show you where my sister-in-law Sophronia's buried. Can't I see it tomorrow, in the daylight? You'll see it now, Sophronia. Hiram, you're hurting me. I'm sorry, Madea, but you must learn to do what I say, and then we shall have no trouble. Just yonder on that mound. I had to whom my sister-in-law Sophronia was laid away 25 years ago. Buried her ourselves, without a service, out here by herself on the grounds. Ethan's buried in town, but not Sophronia. I had a feeling I'd have to keep an eye on her. Keep an eye on her? I knew she was one of those restless sleepers who lay quiet in a grave. You mean you think she haunts this place? Nope, not this place. She never had any use for it. Live or dead. No, she makes for the warmer climates. She was always a cold-blooded little woman, freezing and shivering all the time. Places like California and Texas and Florida, she makes fun. Florida's good. One of her favorite haunts, particularly around St. Petersburg, she likes the flowers and the sun and the romance. Hiram, I feel cold. I'm shivering. Do you mind if I go inside now? In a minute. I haven't explained everything. You see those birches over there? Under every one of them's a grave. See, I found her wandering the Earth in disguise three times. I killed her three times. Still don't do any good. She's still restless. You mean you killed three different women? Yep. Now I keep another grave open. Reminder, waitin' now. Would you like to see it, Sopronia? Oh, no, no, Hiram, no, please, I... Are you afraid to see it, Sopronia? No, I...  Think what, Sopronia? Nothing. Well, I... Well, we mustn't have you catchin' a cold, my dear. When you come back along in the hotel, I'll show you to your room. Why? Room? Yes, Sopronia. Your room. Now this room's cleanest in the hotel. Always expected to be occupied again sometime. There you see. Kept everything just as it was. What's the matter? Nothing. It's just that... Seem kinda familiar? No, no. Just as she left at that afternoon, she walked downstairs to murder my brother. See her embroidery on the table, needle sticking in it. Her hem box still open. She was very fond of singin' hymns, Sopronia was. Had a nice voice, too. I used to accompany her on the harmonium down the parlor. Oh. Well, I'll turn down the bed for you.  No, I don't want any.  You can put on one of Sopronia's dressing gowns, make yourself at home. I... Why are you locking my door? It's safer, my dear. Safer? Always locked doors, outside and inside. Windows, too. Much safer for everybody. It must be nearly midnight now. I don't know... I don't know how long it's been since she locked that door on me and left me alone in this horrible room with its hideous little mementos of a dead murderous. I have lit the pink-flowered oil lamp and I am sitting here at her little wicker table trying to maintain my sanity as I write this. I can hear him downstairs in the shabby little parlor off the lobby playing the harmonium, playing the same piece over and over again. My hand has just brushed against her needlework lying beside the open hymn book open at the same hymn he is playing. The same hymn he is playing. I shuckle mad. I shuckle mad. I shuckle mad. In a moment, we continue with the third act of... suspense. We have together ample capacity and freedom to defend freedom. This is NATO, the North Atlantic Treaty Organization. Day after day, month after month, since April 4th, 1949, the activities of the North Atlantic Treaty Organization have moved steadily forward on many fronts. This complete cooperation must and will continue because the concept of national self-sufficiency is out of date. Countries of the free world are interdependent and only in genuine partnership and by combining their resources, sharing tasks in many fields and progress and safety be found. The United States of America is a part of NATO. You should be aware of and alert to the objectives and programs of the North Atlantic Treaty Organization. And now, starring Mercedes McCambridge, act three of the Diary of Sophronia Winters. February 12th. Can it be only a week since I became the bride of a mad man? Now I live only from moment to moment, listening to each creek on the stairs. Each note visits slowly wheezes from the old harmonium, wondering when he will come for me, when he will drag me out to join those other Sophronias in their frosty graves beneath the naked verges. Sophronia! It's come. Sophronia! Come downstairs. Watch her sing with me. Sing, sing. She sang with him, he said. How? How can I come downstairs when my door is locked? It's unlocked. You try it. Unlocked? Oh no, how could it? Oh it is, it is. And I never knew it. I never knew it. Come in, Sophronia. He unlocked it sometime while I was just sitting there. Oh, why didn't I try a few more times? Why did I just sit there assuming? No. No, he'd have caught me anyway. He'd have known. But I might have got away. It's always too late.  Sophronia! Yes, Hiram. I'm coming. Hiram. Where are you? Down here in the parlor. That's the harmonium? Yeah. Waiting to sing with you. All right. I'll sing. I haven't sung in years, but I'll try. I'll sing with you. I'll stay out here in the hall. My voice will carry better. Always did carry better in the hall, didn't it, Sophronia? Of course you know. Both the front and back doors a lot. Yes, I know, Hiram. All right. There's only one more page and shall I read it to you, Miss? Yes. Yes, go ahead. March 22nd. I have been sick, I think, for a very long time. The pages of my diary are blank, but I shall take you out again for a diary today and start you over again. I shall never look back for other pages. I shall only write on and on about this beautiful place so that no one reading this diary will ever know that I did it. Diaries. I was smarter than he. When I opened that door at the head of the stairs and heard the music, the fireworks still hanging on the wall. Oh, I was so cautious, so terribly cautious. I dipped out like a little mouse, even as I sang the hymn into that room where he was playing. If a reflection of that axe had so much as glibbered across the wood, it even turned. But I was clever, so much cleverer than he. I stepped on singing, and now I'm free. Free the bird. I'm free, and he shall never catch me now, not this time or ever again. Because he's dead. Isn't he dead? Yes. Isn't my dear brother-in-law Highland really dead? Yes, Mr. Frohler, he's dead. And now we'll put the diary away, shall we? Remember what the doctor said. We mustn't overdo with where to get well. Oh, but I don't want to get well. Ever. I like being sick. I feel so safe. Suspense. In which Mercedes McCambridge starred in William M. Robeson's production of The Diary of Sopronia Winters by Lucille Fletcher. Supporting Mercedes McCambridge in The Diary of Sopronia Winters were Carl Swenson and Ellen Morgan. Listen. Listen again next week when we return with Miss Kathy Lewis starring in The Bridge. Another tale well calculated to keep you in... suspense.


Live from San Diego, California, it's theCUBE. Covering KubeCon and CloudNativeCon, brought to you by Red Hat, the CloudNative Computing Foundation and its ecosystem partners. Welcome back to theCUBE here in San Diego for KubeCon, CloudNativeCon with John Troyer. I'm Stu Miniman and happy to welcome to the program two guests, first time guests I believe, Julio Tapia, who's the director of CloudBU Partner and Community with Red Hat and Guru Rao, who's the founder and CTO at Portworx. Gentlemen, thanks so much for joining us. Thank you. Thanks for having us. Happy to be here. All right, let's start with community ecosystem. It's a big theme we have here at the show. Tell us kind of your main focus, what the team's doing here. Sure, so I'm part of a product team. We're responsible for OpenShift, OpenStack and Red Hat virtualization. And my responsibility is to build the partner ecosystem and to do our community development. On the partner front, we work with a lot of different partners. We work with ISVs, we work with OEMs, SIs, pod providers, telco partners. And my role is to help evangelize, to help on integrations, a lot of joint solutions and then do a little bit of go to market as well. And on the community side, it's to evangelize with upstream projects, with customers, with developers and so forth. All right, so Guru, actually, it's not luck, but I had a chance to catch up with the Red Hat storage team. One, back when I was on the vendor side, I partnered with them. Red Hat doesn't sell gear, they are a software company and everything open source. And when it comes to data and storage, obviously they're working with partners. So pull partworks into the mix and tell us about the relationship and what you both do together. Sure, yeah, we're a Red Hat OpenShift partner. We've been working with them for quite some time now. Partner with IBM as well. But yeah, Portworks, we focus on enabling cloud native storage, right? So we compliment the OpenShift ecosystem. Essentially, we enable people to run stateful services in OpenShift with a lot of agility and we bring DR backup functionality to OpenShift. I'm sure you're familiar with this, but people, when they deploy OpenShift, they're running fleets of OpenShift clusters. So multi-cluster management and data accessibility across clusters is a big topic. Yeah, actually, if you could, and I hear the term cloud native storage, what does that really mean? Back a few years ago, containers were stateless. I didn't have my persistent storage. It was super challenging as to how we deal with this. And now we have some options, but what is the goal of what we're doing here? You know, there really is no notion of a stateless application, right? Especially when it comes to enterprise applications. What cloud native storage means is, to us at least, it signifies a couple of things. First of all, the consumer of storage is not a machine anymore, right? Typical storage systems are designed to provide storage to either a virtual machine or a hardware server. The consumer of storage is now a container that's running inside of a machine. And in fact, an application is never just one container. It's many containers running on different systems. So it's a distributed problem. So what cloud native storage means is the following things. Providing container granular data services, being application aware, meaning that you're providing services to many containers that are running on different systems and facilitating the data lifecycle management of those applications from a Kubernetes way, right? The user experience is now driven through Kubernetes as opposed to a storage admin driving that functionality. So it's these three things that make a platform cloud native. I want to dig into the operator concept for a little bit here as it applies to storage. So you now have, so first operators. I first heard of this a couple of years back with the CoreOS folks who are now part of Red Hat and it's a piece of technology that came into the Kubernetes ecosystem. Seems to be very well adopted. They talked about it today on the keynote and I'd love to hear a little bit more about the ecosystem. But first I want to figure out what it is. And I was in my head, I didn't quite understand it.  There's also things that know about cloud like Terraform or CloudForms or you know, Pulumi, all these sort of things here. But this seems like it's a little bit, this is a framework around lifecycle. It might be a little higher in the semantic level or knows a little bit more about what's going on inside Kubernetes. I'll just touch on it. So operators is a way to codify business logic into the application. So how to manage, how to install, how to manage the lifecycle of the application on top of the Kubernetes cluster. So it's a way of automating. Okay, right. And just to add to that, right? You mentioned Ansible, right? So as engineers we're always trying to make our lives easier, right? And so infrastructure automation certainly is a concept here where what operators does is it elevates those same needs to more of an application construct level, right? So it's a piece of intelligent software that is watching the entire runtime of an application as opposed to provisioning infrastructure and stepping out of the way. Think of it as a living being. It is constantly running and reacting to what the application is doing and what its needs are. So on one hand you have automation that sets things up and then the job is done. Here the job is never done.  Nice, nice. But for any sort of lifecycle or sort of project like this you have to have co-chairing and contributing, right? And so Julia can you tell us a little bit about that? What we do is we're obviously all in on operators and so we've invested a great deal in terms of documentation and training and workshops. We have certification programs. We're really helping create the ecosystem and facilitate the whole process. You may be familiar, we announced Operator Framework a few years ago. It includes Operator SDKs. So we have Operator SDK for Helm, for Ansible, for Go. We also have announced Operator Lifecycle Manager which does the install, the maintenance and the whole life cycle management process. And then earlier this year we did introduce also operatorhub.io which is a community of our operators. We have about 150 operators as part of that. How does the Operator Framework relate to OpenShift and versus kind of upstream Kubernetes? Is it an OpenShift and Red Hat specific thing or? Yeah, so Operatorhub.io is a listing of operators that includes community operators. And then we also have certified operators and those operators, the community operators run on any Kubernetes instance. The certified operators make sure that we run on OpenShift specifically. So that's kind of the distinction between those two. Yeah, I remember at Red Hat Summit we talked about it some bit. So give us a little kind of walk around the show with some of the highlights from operators. The ecosystem obviously we've got Portworx here but there's a broad ecosystem. Yeah, so we have a huge, huge ecosystem. The ISVs play a big part of this. So we've got operators, database partners, security partners, app monitoring partners, storage partners. Yesterday we had an OpenShift Commons event and we showcased five of our big operator partnerships with CouchBase, with MongoDB, with Portworx obviously, with StorageOS and with Dynatrace. But we have a lot of partners in a lot of different areas that are creating these operators, they're certifying them, and they're starting to get a lot of use with customers. So it's pretty exciting stuff. Cool, I'd love to your viewpoint on this because of course Portworx, good Red Hat partner, but you need to work with all the Kubernetes options out there. So what's the important of operators to your business? Yeah, OpenShift obviously, it's one of the leading platforms for Kubernetes out there. And so, the reason that is it's because it's sort of the expectations that it sets to an enterprise customer. It's that Red Hat experience behind it. And so the notion of having an operator that's certified by Red Hat, and a Red Hat going through the vetting process and making sure that all of the components that it is recommending from its ecosystem that you're putting it into, putting it on to OpenShift, that whole process gives a whole new level of enterprise experience. So for us, that's been really good, right? Working with Red Hat, going through the process with them and making sure that, and they're actually double clicking on everything we submit, and there's a real, you know, we iterate with them. So the quality of the product that's put out there within OpenShift is very high. So, we've deployed these operators now, the operator that Porek just announced, right? We've had it, we have it running in customers' hands. So these are real end users. You'll be talking to Ford later on today, Harbroot, for example. And so the level of automation that it has provided to them in their platform is quite high. I was kind of curious to shift maybe to the conference here, that you all have a long history, both organizations and both of you personally in the Kubernetes world and the Cloud Native world. We're here at KubeCon, Cloud NativeCon North America 2019. It's pretty big. And you know, I see a lot of folks here, a lot of vendors, a lot of engineers, a huge conference, 12,000 people. I mean, any company's perspective? So I've been at Red Hat a little over six years and I was at the very first KubeCon many years ago in San Francisco. I think we had about 200 people there. So this show has really grown over the years. And we're obviously big supporters. We've participated in KubeCon in Shanghai and Barcelona. We're obviously here. We've just super excited about seeing the ecosystem and the whole community grow and expand. So very exciting. You? Yeah, I mean, like Julio mentioned, right? So all the way from DockerCon to, you know, where we are today. And I think last year was 8,000 people in Seattle. And I think there are probably, I've heard numbers like 12. So it's also equally interesting to see the maturity of the products around Kubernetes and that level of consistency and lack of fracture, right? From mainstream Kubernetes, there's to how it's being adopted in OpenShift, there's consistency across the different Kubernetes platforms. Also, it's very interesting to see how on-prem and public cloud Kubernetes are coexisting. So that's been, four years ago, we were kind of worried on how that would turn out. But I think it's enabling those hybrid cloud workflows. And I think today in this KubeCon, we see a lot of people talking about that and having interest around it. It's a really great point there. Julio, I want to give you the final word for people that aren't yet engaged in the ecosystem of operators. You know, how can they learn more and get involved? Yeah, so we're excited to work with everybody. Our ecosystem includes customers, partners, contributors. So as long as you're all in on operators, we're ready to help. And we've got tools, we've got documentation. We have workshops, we have training. We have certification programs. And we also can help you with go-to-market. We're very fortunate to have a huge customer footprint. And so for those partners that have solutions, databases, storage solutions, there's a lot of joint opportunities out there that we can participate in. So we're really excited to do that. Julio Kube, thank you so much. You have a final word for you. I was just going to say, again, so to follow up on the operator comment, on the certification that Julio had mentioned earlier. So the operator that we have, we were able to achieve level five certification, which the level five signifies just the amount of automation that's built into it. So the concept of having operators help people deploy these complex applications, that's a very important concept in Kubernetes itself. So glad to be a Red Hat partner. Yeah, that's actually a really good point. We have an operator maturity model, level one, two, three, four, five, level one and two are more your installations and upgrades, but the really highly capable ones, the fours and fives are really to be commended and Portworx is one of those partners. So we're excited to be here with them. That is a powerful statement. When we talk about the complexity and how many pieces are in there, everybody's looking for to really help cross that chasm and get the vast majority of people. We need to allow environments to be, have more automation, more simplicity. Story I heard loud and clear at Ansible Fest earlier this year and through the partner ecosystem and it's good to see progress. So congratulations and thank you both for joining. Thank you. Thank you. All right, for John Troyer, I'm Stu Miniman, back with lots more here from KubeCon, Cloud NativeCon 2019. Thanks for watching the Kube.


Hey guys, it's Gabby here with Brain Education TV. If you're new to this channel, consider subscribing. We post weekly videos on wellness tips for the brain. And if you're already a subscriber, welcome back. Today, I'm going to talk about some quick ways to boost your immune system. At a time in our world where we need to be more cautious about the spread of bacteria and germs and viruses, it's good to have some go-to ways to quickly and naturally boost your immune system and fight off any infections or disease. So first of all, why is the immune system so important? Your immune system is like the army inside your body that helps to fight against any viruses, bacteria and disease and what keeps your body healthy. The difference between someone with a strong immune system and a weak immune system is how often they get sick and how easily they're able to recover from any illnesses. So if you're someone who always tends to get sick, always has a cold, always has a flu, it may mean that your immune system is not being managed well. Now let's get into the two tips. Tip number one, raise your body temperature. Did you know that changing your body temperature by just one degree Celsius up or down tremendously impacts the immune system? This has to do mostly with gut health. Your gut contains good bacteria that lives in warm temperatures and bad bacteria that thrives in colder temperatures. So if you're able to raise your body temperature by just one degree Celsius, the bad bacteria cannot survive anymore and you can produce more good bacteria to help you fight off disease. So simple ways to do this would be to maintain a healthy diet and also include warming foods into your diet, such as soups and broths. And also keeping up with daily exercise so that your internal body temperature can naturally stay warm. I'd also like to share a brain education technique that helps to stimulate your gut and raise your temperature and it's called belly button healing. To do belly button healing, you use a simple tool called the belly button healing wand and you gently place it on your belly button and hold it and you pump your belly button in and out.  I'll link below a full tutorial that we made on this channel on how to use the belly button healing wand and I'll also link some more resources such as a course so that you can see how to fully get the effects of belly button healing. Tip number two, boost your circulation. Most of us sit for long periods of time throughout the day so that can cause blood and energy to stagnate within our bodies and cause poor circulation.  This can be done through simple full body exercises such as meridian stretching or joint rotating. A quick and easy brain education exercise that helps with boosting circulation is called body tapping.  When you tap all over your body, you actually tap along meridian channels and points in your body, which are basically pathways in your body where energy and blood runs through. So when you tap there, you release the stagnant energy that is there. I'll link below a full body tapping routine that we have on this channel that shows you how to naturally allow the energy flow in your body again. So I hope you liked these tips. When you can naturally take care of your own internal temperature and your circulation, you can have the tools to take care of your own health rather than relying heavily on medicine and doctors. What do you think? Do you like these tips? Are you interested in trying them? Have you tried them before? Let us know in the comments down below and we'll answer all your questions. Okay guys, that's all for my natural immunity boosting tips. I'll see you in another video.


So we're here at the Mobile World Congress, the ultimate mobile trade show in the world, and who are you? I am Matt Margolis, Director of Business Development and Strategic Relationships at VUZIX. And you're wearing right here the blade. Yes, this is the VUZIX blade. And it's fully mass production right now. You're actually shipping, right? Yeah, we've been working on this for a while. We've been shipping a lot through 2018 to developers and strategic partners, and we're ramping up production. Right now, we're looking at getting up to 2,000 pieces a month by the end of March. So things are definitely getting very exciting. And what's been great is our return rate for the blade has been extremely low. So the folks that are getting it, they love it. It's stable? They're using it. Yeah, it's stable. We've been rolling out a lot of releases. So if you look at what we have, we've rolled out our commercial edition in the fall. We've then added some new features. We've opened up the ability to reply to messages, answer a phone call, receive your notifications. We're going to have an upcoming release here shortly that allow you to get the GPS information off the phone. And what that's going to do is we're going to have some apps like Yelp, which will allow you, let's say you're in downtown Barcelona, you could go outside, look around the city, and it will give you the score, the rating, information that you need on the fly to make your best decision for dining. We're also working with a company called AccuWeather. We're going to have an AccuWeather app, which will give you kind of real-time information on the weather, maybe your last four locations. And this is more than just like a flat file, it would be something more like a video, kind of interactive and fun on the glasses. We're also going to see some new apps from us. So we're going to have a sports score app, a news app, as well as we're working with several folks to do some voice to text and language translation. Really the sky's the limit. If you have the right developer, it's a standard Android. It's been very easy for folks to build applications. The glasses connect to the web via WiFi or Bluetooth. So you're connected to the web, it's an Android device. It's really easy for folks to develop and build applications for the glasses. So you're not just wearing smart glasses, you're not just wearing sunglasses. You have a little screen right there. I do, and if I were to get a text message or a phone call, it would pop up right on the screen for me. With the WaveGuide technology. So can you take it off? So is it, how good is it? Because that's the crucial, crucial thing. So all the people that have been trying it out so far, what did they say? The feedback's been great. I think from, again, developers, it's a real simple, it's Android. You know, if you were a developer and you were to go into our database, you'd have easy, they're set up to be able to develop sample code. It's just real easy to get started and just to build applications. So that part's been great. We also have a great support staff that allows folks to, if they're having challenges or they want to work with us, we work with them directly. And also our app store. I think we're up to about 20 apps and that's going to continue to expand. You've had folks that have been using this, behind the scenes and their apps are starting to come together. So we're going to have new applications, utilities, a lot of information for folks to have just on their glasses. So it's very exciting. So what's been going on in the last few months? Because that's how the CES boosts. It was really action-packed all over these cool demos and it just feels like you're, there's a lot of things happening right now with music. Especially maybe with the app ecosystem or ramping up the mass production. Yeah, I think the biggest thing is we're actually getting the OS or adding new features to the OS to open up the app development. We've been seeding a lot of developers, which has been great, so. So for example, if you put it on, you can maybe show a little bit about the latest version of your app right now. Yeah, so let me open up my phone for a sec here. Is it iOS and Android? Yeah, so this is iOS and Android. So this is our MusicSplay companion app. So it shows you if you're connected, your battery life, the memory. Which is nice if you go to settings. If you want to get into Wi-Fi, you can go and pick a network, you select. It'll allow you to type right on the phones. You don't have to try to play with the keyboard. What's also nice here is if the display, let's say I want it set lower, higher in display, I can move it down. It'll move the actual image down on the screen. If I want to move it up, it'll move it up. If I want to control the brightness, I can make it brighter if it's too bright for me at night. Like move it up or down, so it doesn't mean... Up or down within the window. It's like when you have a projector and you can digitally move the... So right on the fly, you can put this on it'll move the image up or down. So let's say you wanted an application that maybe you wanted a little bit out of the way, you can set it down. And everybody's eye is a little bit different. So some people are set to the middle, some people are set higher. So this allows the glasses to work for almost everybody. But what's the whole resolution right there on the low-key? So right now we have about 28 degrees is the total. And we work with about 20 degrees. So... Is that the place where it projects? Or is it like the whole resolution is on the whole height? The whole... So we only use a portion of that. So what we use in the display is about 20 degrees. The total that's there is 28 on the waveguide. So but because we allow it to move up or down, we're not using the full 28 degrees right now on this current build. Nice. Waveguide is really cool, right? Vuzix has been doing smart glasses for a while, but the waveguide is a different kind of thing. The waveguide's been a, you know, if you look at what's out there, nobody wants to wear big and bulky. And I think what's nice about the waveguide and especially our waveguides is they're very efficient. So unlike some other smart glasses, if you were to go outside, you can't compete with the outdoors. You need to put on a shade. With ours, we actually have a mode on here, this UI mode, which sets a dynamic. And what this does is if I go outside, the glasses are going to respond to the light and actually turn on the brightness and respond. So, which is great, which means on a bright sunny day, like today, I can still see the display. But then when I'm indoors, the glasses know that you're indoors. It's not as bright and it'll dial down the display. That's one of the things that, so this is using DLP micro projector in there. It's a TI DLP. NHD maybe, or a small projector in there that goes through the waveguide, which is totally amazing. But one of the arguments that micro LED people have been saying is that maybe for this kind of application you can have brighter display. You're also talking about potentially working with micro LED, right? Yeah, so if you look at the nice thing about micro LED is you think about a TV and then maybe it's got 10,000 pixels. With a micro LED, you're able to just turn on only a few of the pixels. So you can imagine right now, like when we put an image into display, it lights up the whole display with a micro LED. You can only light up what you need, which means you're going to use a lot less battery. It's more efficient. So that alone will drive improvements in battery, which is another, you know, a big factor for wearables. And I noticed that the glass is not too dark, right? Yeah. So you don't really have to take them off when you get indoors. Yeah, so I went to a basketball game, my family, in November for over Thanksgiving and I wore them during the whole game with them on and it didn't disrupt my vision. It was still clear.  So it's pretty nice. Matt, can we see something else going on in the app? Because it's crucial to have something usable, right? So how many things are working right now? So here's a bunch of apps that we have kind of in development. You can kind of see we've got Alexa, we've got some streaming video stuff, news. You have the Google Assistant too? Google Assistant is not on here. We do have that. We are playing with that internally. And we did showcase that at CES. It's not particularly on mine. And then what's nice here is our, this is our phone. Can you tilt your phone just a little bit? Yeah, so here's our photo. So what's nice is our latest update. It allows you to take a photo right off the blade through Wi-Fi Direct and Connect. So this is, you know, where I'm standing in front right here. You know, right here is what you're seeing. I took this on my blade and then threw our companion app. It allows you to take the information right off the blade. And I can one click and I can send a message. I can send an email. I can add it to Twitter, Facebook, wherever I want. I can share just one click right from, right from my blade to my phone, right to social. This is all done through our companion app that music's developed. Nice. And that tethers to the blade of a Wi-Fi Direct? Yeah, it's a Wi-Fi Direct connection which allows you to take video and pictures and put it on your phone to allow you to do sharing. But the blade itself will connect to your phone through Wi-Fi or Bluetooth. Nice. Otherwise, is one of the main things that is happening right now is notifications that you have going on? And how do you select which ones go in there? Is like a basic smartwatch kind of system? Yeah, so the notifications are controlled actually with your phone. So whatever notifications you enable on your phone. So if I were to go to my phone, so any of these notifications, if I were to turn something on, they'll allow it to go through the blade. So that's real simple. And that gives you, if you're traveling, you have a gate change, any information you need, all that would just show up right on the glasses. So again, this keeps you informed. What's nice about the glasses, if you need to take a picture, you can never miss a shot. You're always connected, which is great. And so let's say I get a WhatsApp message. What can I do with it? Well, if you have Android, you're able to reply through that, through the blade, you can reply through a message. How do you reply? So I don't have it on my, so I'm an iOS user, unfortunately, but through the companion app, you'd actually have, there'll be some canned messages in here. So not in this build, but if you had the Android, you'd have a, it would show up here. Here's your reply. Here's your standard. Like when you're driving in a car and it says, hey, I'm busy, you can put in custom messages that you use frequently. By tap or something? Just, yeah, so right on the glass, if you got a message, you would just click on there and hit reply, and then you'd select a dropdown right on there and just click, Canned messages, right? And just click send, and it'll send it right through. You don't do voice recognition kind of stuff? We're working on voice attacks. I think that's, part of this is adding new features. And what's nice about our platform is, it's OTA, so we can update the OS, we can add new features. We support Android applications. We have an app store. So a lot of what I do in my role is actually looking for partners that want to put in their sports information or maybe streaming video. We're always looking for folks that want to develop and add new features for the glasses. But we have a great canvas. It's a ability for developers and partners to put in information. It's just real easy to get things going. But does it have a noise cancellation? Yeah, there's noise. There's noise canceling mics on here. So it takes just your sound? Yeah. Doesn't it come in from the people next to you? No, it's really meant to be, think about a speaker. It's meant to be picking up what's coming on around you. When we went to CES, we tested our different assistants, Google assistant, Amazon Alexa. We were testing that in loud environments and we were able to do the sound at a close proximity. So the mics are pretty good. They pick up the sound where it needs to come from. Which is great. And I've actually whispered in it quietly before and it just picks it up real good on Alexa, even. And how's the battery life? What's been the response on that front? Yeah, so battery life... Do you plug in the power bank or are they actually good? So for battery life, for me, I've been getting usually about four to six hours. That means I'm doing some applications, some pictures, checking notifications, that type of thing. If I'm going to watch streaming video or I'm going to run the camera heavy and take video, you might get a couple hours. But if you were to limit notifications, you just wanted to follow a couple of things. You'd probably get more than four to six hours, but it's pretty much lasted a day for me on Amazon. So can you take it off? And so there's the little camera over here and the resolution and the quality on that one. People are happy? Yeah, it's an eight megapixel camera here. It does stills in video. So it's high depth video, eight megapixel camera. And what's nice too is people are concerned about privacy. When I do turn the camera on, which I can do for you, there you'll see the red light turn on. So let me just do that for you. So you go through the UI. Yeah, so they go to the apps, a lot of apps on here. It's just amazing. It's like magic a little bit. There we go, ready? You should see that red light turn on here in a second. Yeah, I saw the red lights. I see that. It pops up as soon as you're in the app or when you start recording. As soon as I start recording. So here it is now. You can see the red light come on. So now I'm recording you. Now I'm stopping. So if you looked in here, I don't know if you can get it, but you'd see a picture of yourself recording me. Yeah, so if I went to my photos, you can see it on there. And the camera is nice. You can actually do, there's two modes. One can be the preview mode. So if you wanna actually preview where you're gonna take a picture of, that'll show up and then you tap it. Or if you just wanted to take pictures as a little box and once you take it, you'll get a quick flash. It'll show you the picture you took. And then if I go to my companion app, go to the photos icon, it'll bring over all those photos almost instantly for you to share and do what you want with it. So your role at Musics, are you doing business? Yeah, doing business development. Business developer, yeah. So does that mean there's a lot of potential contacts you're doing right now with all kinds of, let's say we're in this amazing place right here.  Yeah, so I do a lot. So one of the verticals is sports, talking to a bunch of the professional sports teams. That's an area where, with the glasses, if you were in a place like this even and you wanted to look at a marker or some information, I wanna know what I'm looking at here. You could actually put the glasses on. It would give you information based on a marker and it just provides so much information that you wouldn't be able to get it. You won't need a person to talk to you. So sports, museums, that's an area of interest. And for us, we're doing a lot of work today with the wireless carriers. So guys in the US, guys in Europe, guys in Asia, they're interested in 5G. They're also interested in AR. If you talk to some of the companies out there, they're focused on services. They look at AR as another way to consume data, consume information and provide information. But it's also more than that. It's going to the store, going to your grocery store and being able to shop using the glasses, it brings up your virtual cart. There's just so much you can do with glasses once they're connected to 4G or 5G service. Why are you talking with any of those supermarket chains? Like let's say there can be a little deal with the Amazon, I'm just gonna speak out loud, right? Yeah. Because they own big retail markets, what's called the healthy ones. Well, no, I think it's always small. But what I can say is, and then you can enter and maybe they can add into the database and you can get an augmented shopping experience. So how much are you reaching out to all these potentials? So I would say there's multiple large company, big box companies that have grocery arms that are looking at our glasses and actually buying some in these instances and building. So a lot of what we have is if people are going shopping and they place an order online and they come to do a pickup, the glasses can be used to actually scan the order and give it to the customer. So this is one of the use cases in the B2B but also really in the B2C where you have a consumer facing part of your business, grocery stores, big box retailers, they're buying these and piloting them right now in their stores. Are you partnering with Tinder? I just think it could be an amazing little application right there, you could walk around this place, you can see an overlay on who wants to network. I think that's another, it's a great example, I think between Tinder, Twitch, there's a lot of these applications to be able to do a visual, it's a simple interface. Even Twitch to be able to stream. I know you love the camera, so something like that with the right interface, that certainly could work on a glasses. We could go and stream outward. You could also use it to stream and then also receive the messages. So you could stay connected instead of having two monitors you want to check in, you could limit your chat. All that information could be used right on our glasses. I think you can work with like Dubai or something, the Emirates, right? And when you arrive, you leave them your passport, they give you one of these and then you get an augmented two day stopover. And the whole country would be augmented. Okay, I'm just, there's all these, but maybe, the trick is, when do you get to the killer apps and do you have some already or how many can come just around the corner? I think just, it's a standard Android, where you have a camera and you can connect to the real world. It's really limitless what you can do. I mean, one thing now with the latest releases for Android, if you're driving down the street, you can get notifications. So turn left a hundred feet, turn right over here.  So it's, that's even that use case alone is pretty remarkable. You know, think of all the Uber drivers you've been with that have two places they're looking at for directions. Having it right in the glasses, I think would be a great use case. Some people talk about safety. We're going to put in a mode in there, which we can limit if needed. So if it knows you're in motion, you're kind of being in driving mode. But I think it's still a lot safer than other methods out there. So how many Tesla engineers have a sample? Ha ha, because that would be a great little thing. They have this new Tesla Model 3. It only has a little display over there, but it'd be great if they can integrate with that one. Yeah, we're working with theme parks, folks that support the DAF. I mean, really anything you can bring information, we're also using it, teen operators are using it, stores for retail are using it. It's really a great device. Let's say I thought I had a killer app, right? And I wanted to do it. How difficult is it for me to integrate with the API and all that stuff? So you've got to be number one familiar with Android. So if we support Unity as one platform we support, the other thing is Android Studio. So if you're an Android developer, Android Studio you log into our website as a developer. And then from there, we have a whole series of shortcuts, example code. We actually did a hackathon a week ago and the feedback was, it's so easy to develop for your blade. If you know Android, it's just so simple to go and develop. You had a hackathon in the US? Yeah, it was at a local college near us and folks, the winning team, they built a language translation kind of on the fly. So they're able to take IBM Watson, record a sound bite, bring it to the cloud and then bring it back to the glasses and give you the language translation. It's just pretty remarkable. And that was done in 24 hours and it's almost commercial ready. So I'd say it's pretty simple to develop on a platform. I want to have chess master partnership because then I can go in the park, you know, when they have these chess matches and they can tell me what to play so I can be the other guy. Yeah, I think that's, I was actually talking to a guy and I think he's in Finland. He said he's, they're working on a backgammon thing where actually it'll let you, it'll look at the board and actually convert and say, here's the next move you should make based on the glasses and AI agent. So playing games, using glasses for your next move, I think that's all doable and not even in the distant future.  If they can kind of like use this for everybody to network better at the trade show. That's another thing, right? Yeah, we actually got one, there's a surgeon out there. He's actually going to be wearing our glasses at several events, including a TED talk in Costa Rica. So, you know, we're still getting out there, we're getting our word out there, but if there's a lot of use cases for this and, you know, people look at the platform and they're like, wow, this is just a great devices, so much I can do with it. So medical, retail, you know, teleprompter, language translation, streaming information in for the DAF. I mean, it's really limitless what can be done. And so hopefully now this is the Mobile Well Congress, the first one where people are not going to be following Apple anymore, and you're going to show, you know, like Google did the Google Glass, which was like a little experiment, but this needs to be a big, big deal and gets to the next level. This is happening hopefully. Yeah, and I think if you look, if you listen to a lot of these companies, Samsung, Apple, they talk about themselves running into services in some ways, so then the cell phones and the adoption that curve is slowly slowing down in some cases negative. So I think, you know, wireless carriers and other folks are looking at 5G and saying, you know, what can I do to bring innovation? And I think smart glasses is certainly going to be a wave of the future and someday it's probably going to replace your phone.


Hey friends, Flair here with another streamer tutorial. Tonight I'm going to show you how to use snap filters and streamer bot to set up camera filters for your channel point redemptions. Let's get into it. Okay, your first step is going to be going to snapcamera.snapchat.com and downloading the snap camera application. I'll put the link in the description down below. This will allow you to run snapchat basically as a camera source and use the output from snapcamera as your camera source in OBS. And that's the first step at getting this set up. Okay, now that you've got snapcamera downloaded, you can open it up and go to the settings. You just want to make sure that the right camera and resolution and microphone are set. Everything else here doesn't matter that much. Once that's done, you can go into OBS and add a new camera source or video capture device. And as the source of that device, you can select snapcamera and that's going to be how we wire this all up. Okay, now that OBS is using snapcamera as its video capture device, we can now work on allowing our bot to trigger snapcamera filters with actions. In order to do that, the bot needs to be able to reach into the snapcamera app a little bit. So what we do is we set up hotkeys for each of our favorite filters. When you add filters, you can click the little star and make it go into your favorites menu here. For each filter in your favorites menu, you can set a hotkey. I'm going to go to my Rancher one and I'm going to set a hotkey of ctrl, shift, alt, f7. Try to find one that something else isn't using is the basic idea. And then I'm going to save. And this will allow me to trigger that series of key presses from Streamer Bot and that will then toggle this filter. So now we want to wire up these filters to an action in the bot. So I'm going to make a new action. I'm going to use my existing camera manipulation group. You can create as many groups as you want just by typing here. I'm going to call it Rancher because that's the name of the filter. And I'm going to put it in a queue where I have all of my other Snapchat stuff. So that if people redeem it consecutively, they'll queue up after each other instead of just overriding each other. So people don't get jipped out of their channel points. And then inside of the action itself. In the simplest form, I'm just going to toggle the filter, wait 30 seconds, and then toggle the filter back off. So I'm going to go to add subaction and then keyboard press. And the key I want, I want to do control alt shift modifiers. And then the key I want is F7. So I have the keyboard press and then I'm going to add a delay, subaction delay. And this is in milliseconds. So we want 30,000 for 30 seconds. And then add subaction keyboard press and we'll set that same. Actually, instead of doing it again, we can just duplicate. So we just press that same combination again after 30 seconds. And that's it. Okay, this text command is just for testing purposes for now. Eventually we're going to wire it up to channel point redemption as well. Also in the interest of testing, I'm going to go back and change the delay to one second instead of 30 seconds. And then I can go into OBS and type exclamation rancher and see if it works. There we go.  So there we go. It works. Okay, now that we've tested the action, we can wire it up to a channel point redemption instead. So I have a whole another video I'll link to up here and about how to link actions to channel points. But I'm going to do it real quick. I'm just going to go into platforms, twitch channel point rewards and create a new one called the rancher. And it's going to cost six, I'll do 400 channel points. You can set the color, the max redemptions per queue, all that stuff right in here. We're not going to go into it right now. I'm just going to select my action and we'll see if it actually works. So it takes a second or two, up to minutes, depending on the twitch API, but should be there already. I'm going to go to the channel point thing here. There it is, rancher redeem. There it is. I want to go back in and set the delay to 30 seconds instead of one. And there we have it. I would love to know what your favorite Snapchat filters are. Let me know in the comments. I hope everybody found this useful. And as always, I hope you go out and spread love, not hate. Cheers.

Welcome to my talk on overcoming impossibility results in composable security using interval wise guarantees. This is joint work with Wally Maurer. The main question of this work is how to best define security. There are essentially two approaches to defining security. The first one, being game-based security, leads to very simple and minimal security definitions. The downside, however, is that those security definitions not always immediately link to a real-world execution of the protocol. Moreover, if we were to build a cryptographic protocol from any building blocks, then, at each step, we will have to prove an explicit reduction to the security game of the underlying primitive. On the other hand, there are so-called composable or simulation-based security notions. As they compare an execution of the real protocol to the one of an idealized protocol, such a mismatch between the security notion and an execution of the protocol can actually not exist. Moreover, as they come with a composition theorem, we can easily build modular protocols without having to prove reductions at every step. The downside, however, is that those security notions are very strong and thus lead to less efficient schemes or, in many cases, even impossibility results. A large class of such impossibility results is caused by the so-called simulator-commitment problem. So let us consider an example of the commitment problem. Let's say Alice wants to confidentially send a message to Bob. So she might use a symmetric encryption scheme to achieve this goal. So in a composable security notion, we would compare the real-world execution of the protocol to Alice and Bob just using an idealized resource, such as a secure channel in the ideal world. And the commitment problem will actually appear whenever we assume that the shared symmetric key Alice and Bob share might not just be secure, but maybe at some point will actually leak to Eve. A bit more concretely, in order to prove the protocol secure, we would have to show that for any interactive environment, the two worlds are computationally indistinguishable. So the environment might input any message M of his choice and then receive the ciphertext C at Eve's interface. So in the ideal world, the same needs to happen, so it's the simulator's job to actually come up with a ciphertext that looks computationally indistinguishable. As long as the encryption scheme is actually in CPA secure, the simulator can easily do so by just encrypting any arbitrary message of the appropriate length. However, the simulator at this point is now committed on the ciphertext C that does not depend on the actual message. So if in the real world, at some point, the key actually leaks to Eve, then Eve can obviously now decrypt the ciphertext to obtain the message M. Hence we need to reflect that in the ideal world. As at this point, the message is obviously no longer confidential, a naive attempt might be to just hand out the message M at this point to the simulator as well. However, it turns out that for most encryption schemes, the simulator will still not be able to come up with a key K that's not only correctly distributed, but also makes the ciphertext C decrypt to this message M. And in fact, in order to be able to do so, one needs a so-called non-committing encryption scheme. Such schemes are however not only more expensive, but often also require additional setup. This sort of raises the question, isn't there a better way to define this thing compulsively than saying there is this ideal channel with the simulator attached? Because in the end, it seems that in a game-based world, we don't seem to have a problem. And moreover, if we say, okay, that this scheme is secure, if the key never leaks, then why should it be suddenly insecure if the key can leak in a thousand years from now and sort of indicate that maybe you've already learned something about the message now. So it seems that rather than having to always use a non-committing encryption scheme, that it's rather the simulation-based security notion that's just too strict. And in particular, we can observe that we don't have any problem to simulate until the key is exposed and we don't have any problem afterwards. It's just we can somehow not simulate past this event. Yet, giving the simulator only the message length to begin with and asking him to come up with a fake ciphertext is essentially only something we do as a proxy to formalize the confidentiality until this event. I should mention that there have been a number of approaches to overcome the commitment problem. For instance, a large body of work considered allowing for super polynomial simulators. However, even with a super polynomial simulator, one typically still needs less efficient schemes and additional setup. Another line of work considered so-called non-information oracles, which essentially embed a game-based notion in a composable framework. So instead of saying that we have this channel that first only leaks the length and only after the key got revealed, it leaks the full message. In such a world, one would say we have a channel that leaks a ciphertext. However, the ciphertext is subject to a certain game-based security notion. This, however, means that if we want to use this channel, we will still need to prove a reduction to this embedded game, hence it somehow hinders modularity. So in this work, we essentially want to explore whether we cannot circumvent the commitment problem by simply making two separate statements. One about confidentiality until the key leaks and one about the remaining guarantees afterwards. And I should stress here that the goal is really to express the guarantees of our regular schemes, which we have used game-based now for a long time, which seem to lead to many interesting schemes and so on. So we do not want to come up with yet another stronger notion that requires less efficient scheme or additional setup, and we definitely do not want to just give up and fall back to game-based security notions as this means we have to prove reductions in every single step and cannot benefit from composition. So the remaining open question is essentially how could such a notion that looks at separate security statements for different time intervals in a composable framework. And to answer this question, let me do a quick detour and look at how the constructive cryptography framework uses specifications as its main objects. So in the constructive cryptography framework by Maurer and Render, one always makes statements about so-called resources, which are essentially the analogon to functionalities in the UC framework. So traditionally, one might want to show that our real-world resource is computationally indistinguishable to some kind of ideal-world resource. However, we can also make a different, more general statement. So what we can do is we can show that this, our real-world resource is contained in the set of all resources that have some kind of desired properties. And such a set, we simply call a specification and a bit more general instead of looking at the single real-world resource, we can say that we also assume just a specification saying that maybe we don't know about certain aspects of the real-world. And the main statement of the constructive cryptography framework then becomes the one of specification abstraction. So we start with this assumed specification, which might look very scary and about which we might not know whether all the resource contained therein have the guarantees we need. So what we can do is we abstract it by a large specification. And of course, this only makes sense if this larger specification is somehow defined and described in a way that now makes it more obvious that all the resources contained in it have all the guarantees we need and want. And making such a specification abstraction statement, the core of constructive cryptography was introduced by Maurer and Renner in 2016. So if you look at all the papers, they might still use a notion that's much more similar to the simulation-based one of the UC framework. And what this abstraction statement really gives us is flexibility. Because on the one hand, it provides a meta framework with this kind of statement already leading to a lot of nice properties. On the other hand, it does not fix as many aspects as the traditional UC statement you might know of. And in particular, it does not necessarily fix what kind of specification we are allowed to look at. So let's quickly look at the nice properties this kind of statement has. Well, first, we're still making a statement about the real-world resource being contained in an ideal specification. And that means there are no forgotten attacks. There is no mismatch between the security definition and the real-world execution. Second, the transitivity of the subset relation gives us a very basic composition result. Meaning that afterwards, we can forget about this complicated specification and just continue proving results about the one that's somehow easier to deal with. And rest assured that in the end, we can plug the two statements together and get our desired result. Finally, and very importantly for this work is that we can actually... That this view actually gives us a very natural way to formalize multiple guarantees. So we can simply make two statements, so it's contained in this specification and in that specification, and then if we say, okay, it's contained in the intersection, we know that it has both guarantees. And I should also mention at this point that the standard simulation-based notion in the end is just a special case. So we can consider the real-world resource as our assumed specification and the ideal-world resource, including the simulator as the ideal-world specification. And this really shows that this kind of decomposing the ideal-world specification into what we actually want, the resource here, the confidential channel, and the simulator is just a way to define a specification such that it is easy to see that messages are confidential. But the simulator is really, in this view, no inherent aspect of our security notion. It's just a mean to the end, and this will become very important in our notion. What we also have to deal with is that traditionally one would say the two words are computationally indistinguishable, but the abstraction statement is an absolute one. So what we have to do instead is to enlarge this green elliptic specification to a slightly bigger one such that the real-world specification is then actually contained. And how do we do that? Well, we simply map it to the one consisting of all systems which are computationally indistinguishable from the original specification. And such a mapping we call a relaxation. And in particular, one can show that this kind of computational relaxation has nice properties and interacts nicely with applying a separate protocol. And using those nice properties, one can then derive the UC composition theorem or the old constructive cryptography one, essentially as a syntactic derivation rule. So going back some slide, we can then prove a subset statement about the green elliptic specification and later on transform this statement to one about the red specification such that we can plug them together nicely using the subset relation. So with this set, let's go back and see how we can formalize such interval-wise guarantees within a composable framework. And as a quick hint, we actually do so using relaxations because formalizing this as relaxation will exactly allow us to do the same thing. We can then, in separate steps, forget about the relaxations and only in the end apply them and put everything nicely together. So to recall, the problem we had with this naive idea of, let's say, we have a channel that first only leaks the length and only afterwards the full message was that we could not formalize past this key exposure event. So we wanted to make the two separate statements. And this is exactly our starting point. We start with this over-idealized channel we were unable to achieve and now, for both intervals, we suitably relaxed this overly idealized resource. So for the first interval, we essentially want to say, okay, it should behave like this channel, but we don't care about what happens after the key got exposed. And this is actually not so difficult to formalize. I mean, for instance, we could say it's the set of all resources T that behave like this channel. If all the systems just shut down at the moment the key is leaked, or if the environment has to stop once the key is leaked, it doesn't really matter. And I will refer to the paper if you want to know about the details, how exactly we did it in this work. A bit more interesting is how we formalize a relaxation that says, okay, we don't care about what happens before the key got leaked. And in particular, we want that the simulator only has to work from the moment on the key got leaked, and hence it learns the full message and hence can trivially come up with a ciphertext by just encrypting the message. And here what we do is we rely on the extension of the constructive group of framework called constructive cryptography with events that was introduced last year. And we essentially only formalize this kind of relaxation for so-called external events. So for instance, here in the channel, whether the key leaked or not is actually not something that's decided by this confidential channel, but something in the ideal world by the environment. So what we can do is within that extension of constructive cryptography, which I have an example of here. So in this extension, there is some kind of global event history on which all the resources can depend. And in particular, the events that are noted there are not necessarily something triggered by the actual resource, but it could also be the environment triggering them. So for instance, we can say that the confidentiality of a channel depends on whether the key leaked or not, where this event is something that's just up to the environment to decide. And this allows us to really say, OK, we only look at the channel in the world where this event already initially happened. So putting it all together, we see that for each time interval, we can formalize the respective guarantee as one specification, and which we can then all intersect in order to get the conjunction of all the guarantees. And I should really point out that while each of those specifications will probably be described by using a simulator, those simulators do not have to be the same one. And this is really what allows us to avoid the commitment problem. And to see that this is not something bad, we really have to take this specification-based view where we see that having a simulator is not something that's somehow inherent to a simulation-based notion. But in the end, it's really just a way on how to define specifications. So why should there be a need for separate specifications to share the same simulator? And on a more technical level, we then formalize those interval-wise guarantees as relaxations of the same overly idealized resource. And we did it in a way that we could prove nice properties about these relaxations, such that we get all the desired composition rules we would like to have. And really, for the details, I would like you to refer to the paper, but what let me repeat once more, what's really nice is that then in every subsequent statement, we can just assume we have this overly idealized resource and forget about all the nitty-gritty details. And only if we do somehow the overall bookkeeping, we have to apply all the relaxation and see what we really got in the end. So in our work, we also looked at some additional examples, such as identity-based encryption, for which it has been proven by Haufein's Martin Maurer that the UC simulation-based security notion is impossible to achieve in the standard model. However, using our interval-wise guarantees, we were able to come up with a composable notion that is not only achievable, but that actually turned out to be equivalent to the standard in the NCPA notion. As a second example, we looked at coin tossing via commitments, and obviously we could just say, okay, we take a UC commitment, but then we would need setup. And what we were able to do here was, we were able to come up with a formalization of commitments that don't have to rely on setup, yet then the coin tossing protocol can just be applied using the composition rules, and we don't have to prove any explicit reduction. So to conclude this talk, what we really did was, we took this specification-based approach of the constructive cryptography framework and used the flexibility it gives us. And in particular, we defined so-called interval-wise specifications, which have very nice, which are defined and built in a way from smaller building blocks that interact nicely with other aspects of the framework, such that in the end we get strong composition rules, and moreover, it allows us to circumvent the simulator commitment problem. Thank you for your attention.


Hi folks, Larry Pesavento for TFNN giving an update. We've got the market down quite a bit, down about $260 in the Dow Jones and the Russell is down about $36, Dow Jones down about $39, Gold is up about $20, Silver is up $0.50, the grain markets are getting decimated folks, corn, soybeans, wheat, all of them getting really hammered quite a bit. And so that's telling you that the bottom in some of these things is far off. So let's pay attention to that because that may mean that we're going to get a break in some of the inflation stuff that's going on. We've got a number tomorrow that's going to be very, very important. I believe it's the jobs number that will tell us how the economy is starting to turn as we look at some of these other markets moving around. The foreign currencies, the dollar, it has been backed off a little bit, was really strong earlier in the morning, but it's given some of those gains back. But the big thing is the fact that the stock market, particularly the Russell index, is getting so hard hit. I mean, my goodness folks, it's below the lows of March 3rd by a substantial amount. And we know the importance of that low. And that's telling us that, oh, something is not right. And that's what you really have to be aware of because the banking stocks, as you know, are getting absolutely massacred. If you look at the regional banking index, it's making sharply lower lows with a price objective at least 15% lower. The price of JP Morgan in the last three days has gapped down every day and today with the largest gap of all. And coming into that number tomorrow, somebody must know something. So be very careful here, folks. You have to use stops when you're in these markets because if you don't, if you don't, that means that something is amiss because mother market does not like for you to laugh at her. And if you say you're not using a stop, you mean to tell her that I know more than you do. And I can promise you that, folks, that is never going to happen. Remember, it's the first mistake teaches, the second mistake kills. And remember what Sun Tzu in the art of war said, don't ever stop your enemy from making a mistake. So live every day in an attitude of gratitude and we'll see you tomorrow. May God bless.


We are not saying those idioms don't exist In our parliament, you can't even say Jesus Christ saves and delivers people from evil spirits The speaker who say unparliamentary withdraw that statement and yet it's the gospel but in that decoramu theirs they have agreed on a certain kind of language that fits their discussion Zamiya is not different We are not a country without morals We are a Christian nation for heaven's sake This vote in Kavata is a vote on behalf of the Zambia people This is a vote to punish liars This is a vote to make sure that Miss Haka in the HDM should put his batoks down and think before he takes action This business of troubling people's lives is a vote to put a vote on behalf of the Zambia people but we are not a country without morals We are not a country without morals So the vote on behalf of the Zambia people is a vote to make sure that Miss Haka in the HDM is a vote to punish liars Waju jubu htiki makingwa htiki rinjita.

And as long as it's an insult to Alexander, you are interfering with his freedoms as well. The same freedom of expression you want. You are now interfering with his freedom of respectability so that he can be honored for who he is. He can also fight you back. So, I don't think zambians should debate this. I think the church should move in and put a stop to this. We are not saying idioms are not going to be used. They will be used but appropriately in the places that should be used kama kiwutanit shotu, handsawado. amounto sema, issangimip.

In Bemaha there are certain ideals, there are certain expressions in soselo which we use in Bemba that may sound insulting that are colloquial in their nature but they are not insults. If you tell somebody that was that is not an insult. It simply means take it easy. That's the meaning. Take it easy.  I'll give you examples of Bemba Indians that are colloquial in their nature. That sound insulting but they are not insults. For instance, you can say ni wukala wambua wengila wuche wuche. Uyuta ato uyu. Uyushimulenga. Simply meaning is a person who does things slowly but sure. It simply means is a person who does things slowly but perfect. It gets perfect result. It's not an insult. There is a saying in Bemba. That's not an insult. It simply means give facts as they stand. Give facts as they stand. It's not an insult. It simply means you can never marry a close relative because that is incest. You cannot sleep with your close relative because that is tantamount to incest. It simply means you cannot notice your own mistakes. You cannot notice your own mistakes. All it is difficult for you to come to see your own mistakes. That's the meaning. But for those who are listening to these Bemba Indians and in Soselo may think that is insulting. It's not insulting at all.

Mae bethau ar gweithio o gyfwyrdau o gyfwyrdau o gyfwyrddau o gyfwyrdau, we have to look to manage our cities from this perspective. From here it's important to realise that as cities grow, urban development enrolls dissect and bisect ecosystems. They reduce the total area of ecosystems, but it also hinders the flow of organisms, nutrients and energy between those ecosystems. That fragmentation erodes biological diversity but it also erodes resilience. Here is a map for Montreal that shows how high ecological connectivity in red has been eroded over the last 50 years. Patterns of urban sprawl like this are typical in cities all over the world and they're diminishing the contribution of ecosystems to urban resilience. What I want to show you next is how to transform that pattern through time. What you see here is that that pattern takes the form of a tipping point, a nonlinear negative relationship between ecological connectivity on the one hand and urban growth on the other. You see this sudden collapse like that, that's typical of tipping points. And it's very hard to slow, let alone reverse tipping points like this. My research at McGill University has used theory, experiments in the lab and the field to show that when you disconnect ecosystems, you erode biodiversity and you erode resilience. But if you reconnect the ecosystem with links and critical nodes, you can recover resilience through time. In 2009 I received a remarkable phone call from the Quebec government. I was asked to use this research to design an ecological network for the city and its entire region. This was part of a broader strategy to improve the city's resilience to ongoing climate change. You can imagine I was daunted by the scale of that request, but we rose to the challenge by forming a big team of researchers. We combined network science with different types of data on ecosystem quality and the movement abilities of different types of species. By combining this information, we could address the multiple dimensions of connectivity in the region. So with this measure of ecological connectivity, we then combine projections from climate change models and land use change models to figure out how the connectivity of the city's network would change into the future. Our algorithm calculates the impact of removing or deleting an ecosystem from the network. In this way, we could rank the contribution of every ecosystem to the connectivity of the whole system, which is needed for management and planning. What I'm showing you here is a map of ecological connectivity for the region today. In dark green you see the ecosystems that have high ecological connectivity and in red and yellow regions of low connectivity. So we can maintain connectivity by protecting those areas in green, but we can improve connectivity by restoring ecosystems in zones in red and yellow. But what about the future? Here is a projection out to 2050. This is a business's usual scenario in which climate change and land use change have continued unchecked. Ecological connectivity has collapsed in fact. We found that with scenarios like this that we could maintain 75% of the region's connectivity by protecting the top 17% of ecosystems. Our algorithm and our model also allows us to identify fragments that contribute multiple benefits. Here you see in light green the forests within the city core that mitigate urban heat extremes, that provide urban cooling, but they also maintain biodiversity and carbon storage. We're working now with the city, with environmental NGOs, with businesses and with citizen groups to revision the city's green belt as a living network. Constant engagement and communication in the planning and implementation process has rapidly shifted the perception of the value of these ecosystems to the city as a whole. That's a fantastic outcome of the research. This science can be applied to any city in the world. I'm excited to be here with you today to figure out how we might go about doing that. Urban ecosystems provide so many benefits to human populations, but managing urban ecosystems as a network will ensure and restore the resilience we need for that sustainable future that we're all aiming for. Thank you very much.


Writing creative stories is something that a lot of GCSE students really, really struggle with. In fact, if you're somebody who usually finds yourself staring at the sheet of paper, either an image or a question asking you to write a story and you don't even know where to begin, you're not alone. In fact, a lot of students really, really find this question quite challenging. Therefore, I'm gonna go over firstly how to effectively plan a creative story and a creative writing exercise and essentially the framework, the structure that you should use every single time, which will guarantee you, number one, a really strong essay writing structure for your creative story. But most importantly, number two, if you practice it enough, you will find that you are really securing some top level marks. These are level nine's and level eight grades, okay? So, as you can see behind me, essentially, you will see a mountain. And maybe you've kind of heard your primary school teacher mention this before, the story mountain structure. This structure is so important. A lot of people learn it and actually practice it a lot in primary school and then when they go to secondary school, they just forget it. They think that, oh, actually, that belongs in primary school and they don't realize that all stories, when you look at even novels, films, they are fundamentally the same. They have what we call a story mountain or a story arc structure. This, the fancy jargon for it, the fancy word for it, is actually what we call the hero's journey. So when you watch any film, the hero, the main character, the protagonist goes on a journey. This is the same for stories and this should be the same for your creative writing exercise. Actually, what you learned back in primary school, that is still relevant in GCSE level, okay? So firstly, the one thing that you have to remember when you're writing an amazing creative writing story and writing a really powerful story is you want to adopt the hero's journey, the story arc, okay? And there are five components to a creative writing story that therefore means actually, when you're planning this and you're considering these five components, that therefore means your creative writing story and every creative writing story should have a minimum of four or five paragraphs and each paragraph should include an element of this. As I mentioned, these five elements are, number one, what we call the beginning in the hero's journey, then number two, what we call the build-up in the hero's journey, then number three, this is the problem, number four, the resolution and then number five is essentially the ending of the story. This is basically the structure that you should take when planning and ultimately writing a very powerful creative story. Now, what goes into each of these paragraphs, what goes into each of these sections in your creative writing story and as I've mentioned, you want to be writing minimum four to five paragraphs, however, you can combine some of these sections. For instance, you can have your beginning and your build-up in the same paragraph, you can have your problem and your resolution in the same paragraph and then your final paragraph can be the ending, however, to make your life much easier, it's better to kind of have it in five separate paragraphs. Now, in the beginning, you essentially set the scene, so you describe the setting, you introduce the character and then you also introduce the atmosphere. I would suggest for the beginning of your story, try to make it really promising, really positive and keep your characters to just one maximum two. Do not start adding five different characters, you only have a limited amount of time to write your creative writing story, okay? You can't, you're not writing a novel, you're writing a very brief story under time conditions, therefore keep it simple, okay? Then the second component is the build-up, this is where your character, your main figure goes on an adventure, they go on a new journey, okay? And the setting, and I would suggest keeping the setting the same, so for instance, if it's in the forest or woods, they start on one point of the forest or woods, they go through and they start an adventure. Also, I will suggest in the build-up, this adventure is quite positive and promising, therefore the atmosphere should be really positive, promising, pathetic fallacy, so in this instance, for instance, you can have the sun smiling down, there's birds twittering in the air, that kind of thing that conveys a really positive atmosphere and it makes us as readers really excited. What's going to happen? How is this character, the main character, what are they going to experience? Then of course, you now have the twist, you have the problem, this is the third element and what you want to do is now gradually shift the atmosphere, make it foreboding, ominous, foreboding and ominous meaning scary, you get the sense, it's not necessarily you're telling your reader that there's something that's hidden or some danger that's coming, but you're gradually introducing elements that make your reader think, okay, something is about to happen, okay? So this is what we call foreboding and ominous atmosphere, you gradually building it up, it goes from being maybe sunny to being dusk or twilight, okay? So this is the kind of weird time of the day around five or six PM where the sky turns kind of this orange, darkish, purple color. This is an indication maybe to your reader that things are about to get really bad, okay? Also in your problem, of course, this is now where you can gradually introduce either the villain or the obstacle that the person faces. Maybe they walk through in the forest, there's a hole that they don't see covered with leaves and then they fall through that hole, okay? But before that, you've built up the atmosphere, you've kind of created some kind of ominous feeling. Then the fourth element is the resolution. Does your character fight the villain? Do they fight something an animal? Or do they run away, flight, so fight or flight? How do they resolve this issue? Do they resolve the issue at all, okay? Again, don't forget, this is timed conditions so you don't have that much time to be having lots and lots of different resolutions, different things, keep it simple, keep it interesting but simple and that is possible, okay? And the final element is your ending. So how does the character change? Bear in mind, for instance, as you can see here, the character starts here, the mountain then ends here. It ends at a different point because your character is somehow different. They have somehow evolved throughout this process, okay? Or your ending can be a cliffhanger. Something can happen and then you end with a cliffhanger, something sudden can happen and everything goes dark, okay? So you've got a choice of that kind of ending too. Now, when you are planning this story, always remember a few things, okay? As I've mentioned, the creative writing story, especially when you're writing it in timed conditions, you don't have that much time, okay? So firstly, adopt the five paragraph structure, beginning, build up, problem, resolution and ending. Then the other element to remember is, have a maximum of two characters. I would even suggest keeping it simple to just one character and then maybe there's a villain so that would be the second character, okay? Then maximum of two settings, again, I would suggest keep it really simple, keep it to just one setting and then the setting can change. The color and the sky and so on can change, okay? But keep it to one setting. Don't start off in the forest then you find yourself in the city. Then you find yourself in the beach. That's too much and you don't have enough time to do that, okay? Keep it really simple but go into lots of depth. And the final thing is, make sure you use figurative language and powerful adjectives. When I say figurative language and things like similes, metaphors, alliteration, onomatopoeia, powerful adjectives could be, for example, when you're talking about crepuscular, for instance, which just means like a very weird darkening color, using really interesting adjectives which are a little bit advanced, a baleful night, baleful meaning menacing, sinister, that kind of thing. And this is part of expanding your vocabulary. It's so important. Don't say, for example, the character feels sad, maybe they feel melancholic, okay? And this comes with reading and preparing, okay? So hopefully this explains to you how to structure your creative writing answers. I would always encourage when you're writing a question, make sure you pause for a second, have five separate points, okay? Don't spend too long planning the story, okay? You need to actually write the story. This should take you no more than five maximum seven minutes of planning, but you need to have a clear plan. What goes into your beginning? What goes into your buildup? What goes into your problem? What goes into your resolution? And what finally goes into your ending? Really brief bullet points. And then maybe as you're making the bullet points, you can write really interesting adjectives or just very brief one word terms that you can relate to in the story. And then of course you go into writing your story. Keep it simple, but very detailed at the same time. So now let's look at some examples of creative writing questions that I have written some really strong model answers.
