In this talk, I want to look at Kubernetes from a developer point of view, more from a Java developer point of view. So I work with Red Hat as an architect. I contribute to few Apache projects and I have two camel related books. So more and more businesses are moving to microservices, and that has been further enforced by making containers accessible to developers to Docker, which in turn enabled DevOps practices. I'm saying that all these forces do change the way we design, implement, and manage Java applications. If you don't change the way you design the applications, you won't succeed in microservices. So what is a Cloud Native? There are many definitions out there and I just added mine. A Cloud Native for me, these are applications which are implemented following microservices principles. They typically run on containers which are managed by platforms on some kind of Cloud infrastructure. By Cloud, I don't mean necessarily Amazon, but more infrastructure that can scale up and down, that can come and go, and if you don't design your application to succeed to survive in this kind of environment seat, you won't succeed with microservices. That also means that any container orchestrator is basically a Cloud Native platform, and there are many of those as you can see on this diagram. In this talk, we'll look at Kubernetes more in-depth, but all of these container orchestrator engines are maturing at the moment and they provide similar capabilities, and more or less they have a future parity at the moment. I think your application will need to have this Cloud Native design patterns if you want to run your application in one of these environments. The bottom two are slightly different. They are actually the one who coined the term Cloud Native from Spring Cloud and Netflix OSS, but they were started way before containers were popular. So they are more based on Amazon images and having a Cloud Native platform as a part of your Java application rather than a separate thing. Now, let's say you decided to use Kubernetes as a developer. There are actually a number of ways to run Kubernetes just by using your mouse without have to run any scripts. So Google Cloud and Microsoft has a Kubernetes cluster as a service. Red Hat's OpenShift Online, you can create an account and use a multi-tenant environment. So basically you share your cluster with other users. But probably for developers, the more interesting options are Minicube which is a lightweight VM where you can run it locally and have a Kubernetes running, or the Fabric8 Maven plugin which relies on Minicube but allows you to manage your Kubernetes cluster straight from Maven. So as a developer, you can start and stop Kubernetes cluster from Maven. You can deploy your application, update it, etc. A few words about Fabric8. It's a project that enables developer to write microservices on Kubernetes. So if you are a Java developer and looking at Kubernetes, it's a really good place to have a look and to start from. You have to learn a few Kubernetes primitives and concepts. So inevitable, there is some learning curve. So you have to know containers, both labels, namespaces, etc. But once you started with Kubernetes, the next step is you have to write your Java application and package it here. We can see which one is the most popular framework at the moment. That's the spring put. But following the same trend, other frameworks such as Wildfire, Swarm and Carav are also turning into this Uberjar format. So at compile time, you create your application as a Uberjar with all your dependencies, which makes it easy to put in a Docker container. All of these frameworks, basically offer you things like HTTP server, REST, JSON, health checks, etc. Once you have your application written in Java, the next step is to put that in a Docker container. There are a number of issues when you want to put Java in a Docker container. Do you want to put the JDK or Jerry if you put the Oracle JDK in a Docker container and push that Docker container to Docker Hub. You might be violating Oracle licenses, so you might have to use Oracle OpenJDK. Other issues around CPU and memory, for example, Java at the moment doesn't see the memory that's allocated to your container, but it sees all the memory on the host. Similarly for CPU, it sees all the cores on the host rather than just the cores specified for your Docker container. I've put here a few examples and workarounds how you can get around those, and the OpenJDK issue numbers which fix these issues. So future versions of Java will be easier to run in Docker, but at the moment you have to do some kind of work around and basically there are a lot of container best practices you have to learn before going into containers and Kubernetes. Again, there is a Maven plugin from Fabric which allows you to build a Docker container from Maven. So at the end of your build process, in addition to your regular Maven built, you get the Docker container that's built from your project. The good thing is it's based from your POM file. So your POM and your Docker image are in sync if you add a new dependency to your POM that gets into your Docker image. Once we have our Docker image, the next step is talking to Kubernetes, basically telling it how to run our Docker image. The way to do that is basically you have to write, I called it application descriptor, but that's either JSON or YAML, and you have to tell it how much resources to give to your Docker container, what dependencies it has, what ports it needs, etc. With Maven plugin from Fabricate, you can generate such a YAML file, again, directly from Maven. At the bottom, I put an example, a couple of Maven commands. So with the first one, we can start Kubernetes. With the second one, we can build a Docker container, and third one, we deploy Docker container into Kubernetes. This makes Kubernetes almost like your application server running locally, where you can easily start, deploy your Docker containers, update them, shut it down, etc., etc. Now, for your application to be Cloud-native or to run on Kubernetes on similar environments, it needs to provide certain capabilities, and the first one is it has to be observable. What I mean by that is it needs to have endpoints where the managing platform can check its health status. We can see that popular projects such as Spring Boot, Drop Wizard, Wildfly, they all have libraries which allows you to expose the health status of your application. So your application needs to tell that it's healthy that it started, etc., etc. Kubernetes by default will check that the Docker process of your container is up, but that's usually not enough. We have seen in the Java world, many examples where the JVM throws out of memory exceptions or the JVM is still up, but it's actually not functioning. So to catch these issues, we have health checks. Actually, the concept of health checks is so important that it was added to Java EE proposal. You can see at the bottom health checks and configuration management. So at some point, it will become part of Java, but unfortunately, I believe it was revised again and it has moved to Java 9. But you don't have to wait for Java 9. You can use any of the existing libraries and just add health checks to your application. The other important piece is your application needs to listen to the signals that are coming from Kubernetes and similar platforms.  Similarly, there are other events like pre-stop, post-stop, you have to listen and maybe you have to do something. In the future, there might be signals, for example, for your application to shrink and consume less resources or maybe to replicate itself, et cetera, et cetera. Here is another example about service discovery and law balancing. In the Java world, what we used to do is, when we write and produce a service and we scale that, typically we have in the JVM some agent, like a Zookeeper agent or a Eurica agent that registers the server into some registry and the service consumer also has a similar agent and looks up in the registry and this is how you find the service. In the Kubernetes world, actually all that is handled by the platform. Well, with Kubernetes you don't need any more agents or actually you are also not tied to Java. Your services are directly registered by the platform and then also updated in the proxy. So on the consumer side, when you call a service, you just call the proxy and the proxy finds a instance of the service and it does law balancing, et cetera, et cetera. So we can see this is just an example how some kind of non-functional or close functional requirements are moving away from the JVM to the platform.  Once you have health checks and listen to events and service discovery, basically this allows you to further do till it's like rolling the deployments.


Alcohol withdrawal is a bitch, maybe you're suffering from headaches or you can't sleep or you really want to drink and you're stressed out about it.  First, you might want to grab my free book, The 30-Day No Alcohol Challenge, How to Reduce or Quit Alcohol. There's a little link in my about section down below and there's a little annotation here as well. You can click completely free book just to help you stay quit from alcohol. So we're going to go over a few supplements that I know have been proven to help when you're going through alcohol withdrawal. I went through this myself. I was a social drinker for many years and in 2010 I took a 30-day no alcohol challenge just to see how I would feel and in the first 10 days I kind of like my sleep wasn't that good and I was a bit irritable because you know I'd build up this tolerance to alcohol and all of a sudden I'm going like 7-10 days without drinking. It's like a shock to the system, right? But I'll tell you, the good news is that after about 10 days everything started to just get better. I slept better. I lost weight. My skin proved. I felt healthier and so it does pass, okay? But while you're going through that, a couple things to help you that don't involve taking supplements obviously is just going for a walk, breathing, meditating and I don't mean like having to sit there for an hour on end. Even just two minutes, just sitting down and breathing in and just doing that for two minutes. It's amazing how the headaches and the stress and the anxiety starts to subside.  So when you're going through that withdrawal, try those natural things first because they can help you a lot. If you're wanting to take a few supplements to help you, I've got a few things that have proven to work here and I'm the creator of the 30-day No Alcohol Challenge and these are some of the things that some of my members have taken when they quit alcohol to help them with their withdrawals, okay? So these are proven. So NAC, and by the way, just before I go over this, make sure you do consult with a doctor first, okay? I'm not a trained professional. I'm not a doctor. I'm just someone who quit alcohol, went through the pain and suffering and then created a program to help people quit alcohol for 30 days and then I'm, you know, like I said, I'm the author of the book, The 30-Day No Alcohol Challenge, How to Reduce or Quit Alcohol. So I'm not a doctor. So take what I say with a grain of salt. This is what's worked for me, but please consult a doctor, okay? So NAC here, it helps the brain when it's going through withdrawal and several human studies have found that it reduces the desire for alcohol for, yeah, yeah, okay? So NAC, lithium orate gives you lots of healthy brain minerals. About 25 grams of that will give your brain extra nutrition just to help you out when you're going through that alcohol withdrawal. Vitamin C, I've got some here. This is the vitamin C that I take. During alcohol withdrawal, your immune health system is compromised due to added stress. Like when you're not drinking after you have been drinking, you're putting stress on the body because it wants that drug, right? Alcohol is a poison. The University of Michigan health system suggests that if you supplement with vitamin C to rid the body of excess alcohol, then that helps with the withdrawal symptoms, okay? I'm just reading my notes here that I typed out before I started recording this. B vitamins are super important. Let me just change the camera down here. B vitamins, B1, alcoholics or people who drink a lot are deficient in this vitamin because it gets used up breaking down alcohol and sugars and carbohydrates. So if you take any one of the B vitamins, that's really going to help you. Niacin is one of those ones. B3, this is niacin right here. This is a brand that I've used in the past. High doses of that is helpful in reducing alcohol cravings, stabilizing your mood. But just be conscious of niacin because it does cause a little bit of flushing. We've had some people in the 30 day know alcohol challenge, you've taken it and they're like, oh, my face got really warm and hot. So it does cause some flushing, but you know it's working if you feel that way, but just be conscious of that. That is one little, I guess you could call it a side effect. B6 and B9 in high doses reduces alcohol cravings and anxious tension. Vitamin A helps to correct deficiencies during withdrawal. Let's just go down here. Fissile is really good as well. Kudzu, Kudzu is an interesting one, a medical Harvard study rather found that Kudzu decreased the desire to consume alcohol within 90 minutes of taking it apparently. And then we've got, I hope I'm going to pronounce this correctly. It's called Sumeran. I don't think I got that right, to be honest, but it improves blood, sugar and liver function, both of which may be impaired after long term alcohol abuse. L-glythothine is a great liver D toxifier, which is again really good and helps you with your withdrawals. And any of those supplements is certainly going to help you. You don't need to take supplements that you don't need to.  Trust me when I say, this is from first-hand experience, the pros of not drinking far outweigh any temporary illusionary pleasures that you get from drinking alcohol. I know I haven't touched a drop of alcohol since 2010. Like I said, I was a social drinker, I enjoyed it. I got drunk on the weekends sometimes. I was never an alcoholic, but I was just a good, solid social drinker. But as soon as I quit, everything changed. I lost weight, my skin improved, I slept better, I felt amazing, the quality, my relationships improved, and I just feel amazing. So there you go. I hope that helped you deal with alcohol withdrawal symptoms. If you want to grab my free book, it's called the 30-day No Alcohol Challenge, How to Reduce or Quit Alcohol. Again, there's a link down below in the about section and there's a link right here. Grab that free book and good luck in your lifestyle of either reducing alcohol or quitting alcohol entirely. I'll catch you on the next one. Are you asking yourself right now, am I an alcoholic? Maybe you drank too much over the weekend. Maybe you've said the wrong thing. Maybe you're drinking a lot and you go...


Alright, so before the break we were seeing that Amos in chapter 7 starts describing a vision which God has given him.  The wall is not completely straight, it is slightly sloping away and the Lord says that the nation in the same way is crooked and so He is not going to spare them any longer. That would be in verse 8, so the Lord says, look I am setting a plumb line among my people Israel, I will spare them no longer. And so as a result in verse 9 the Lord says, I will destroy the sanctuaries of Israel. You know that's basically the temples, all this golden calf temple and all the other idol worship temples which have been established. The Lord says, I will destroy all those, He says in verse 9, all the high places of Isaac, I will destroy, He says. And the Lord also says, with my sword I will rise against the house of Jeroboam. And so when Amos is giving these prophecies, Amazaya, who is like the high priest, he is one of the main priests in Bethel. He is very, very angry with the words which Amos is speaking against them. And so he sends a complaint to Jeroboam II who is sitting on the throne.  He says in verse 10 and 11, so he instigates the king against Amos and the king is very angry. And then maybe we can read out verses 12 and 13. This is what Amazaya says to, first of all Amazaya stirs up the king against him. And then Amazaya, this is what Amazaya says to Amos verses 12 and 13 in chapter 7. Chapter 7 verse 12, then Amazaya said to Amos, go you see, flee to the land of Judah, there eat bread and their prophecy. But never again prophecy at Bethel, for it is the king's sanctuary and it is the royal residence. Okay, so Amazaya is saying, first of all why did you come over here? You belong to the southern kingdom, you go back over there, you earn your livelihood over there. This is what he says. He says, go back to the land of Judah, earn your bread there and do your prophesying there. Why are you coming over here? You know, you're not even wanted over here. So which is when Amos speaks those words and he says, I'm neither a prophet nor the son of a prophet. I was just a shepherd, I was looking after my orchard. God told me to come and speak this judgment against you. That's the reason why I have come over here. And then this is what Amos says to Amazaya. This is the words of judgment which he speaks to him. Very, very strong words. That would be verses 16 and 17. Yeah, 16 and 17 if someone could read out. Now therefore hear the word of the Lord. You say, do not prophesy against Israel and do not support against the house of Isaac. Therefore the Lord, your wife shall be a halosh in the city. Your sons and daughters shall fall by the sword.   Okay, so this is the words of judgment which Amos speaks. He says, you have spoken against me. You have tried to stop my ministry by giving a complaint to Jerobo on the second. You have done all that. But this is what the Lord says and very shocking words.    And so what did he mean when he spoke such strong words? When we look at Amos chapter 3 verses 14 and 15, we will see the kind of lifestyle which these people were living in Bethel. So if someone could read out that first, Amos chapter 3 verses 14 and 15. That in the day I punish Israel for their transgression. I will also visit destruction on the altars of Bethel and the horns of the altar shall be cut off and fall to the ground.  The houses of Ivory cell Paris and the great houses cell have an end says the Lord. Now this is the kind of lifestyle which these rich leaders, spiritual leaders, political leaders of Bethel were living. They had winter houses and summer houses. We earn our entire life to buy one house and these people they had multiple houses. So in summertime they will go and stay in a higher level in a summer house. When it becomes cold in the winter season, they'll come down and stay in another house. So they had multiple houses and their houses had Ivory on the inside decorated with Ivory. I mean they were living such expensive lives. And this is what the Lord says when the judgment comes upon you, when the Assyrians come and attack. I will tear down the winter houses along with the summer houses.  So poverty will strike the people. So imagine what would have happened to Amazaya's family. Amazaya would be in a very wealthy position. His wife would be in a very honorable position. But once the Assyrians come and attack, he will be taken away as a slave. He will die in some pagan country. It is said that his sons and daughters will fall by the sword. So now what happens? The wife is left. She has no money. She has no support because her children are dead. Her husband has been taken away and she would be forced into prostitution. So those are the kind of judgments that God speaks against Amazaya and his family. And in fact against the entire people of northern Israel. So Hosea was mainly used to give a last message of hope. Amaz on the other hand was used to talk about the very terrible things which will happen if the people do not shape up. So God used these two prophets to express both judgment and compassion and give a final chance. Assyria had become very powerful by this time. So all the surrounding nations were really very very afraid of what's going to happen next. And in a time like this God is still saying I can protect you. I can change things if you choose to respond. But the people had become so hard in their hearts that the seeds which were falling, it didn't even penetrate. On the other hand if they had dug that hard soil, if they had started responding then there could have been a great change. God would have stopped Assyria. God would have defeated the Assyrian king. Miracles would have happened for them. But the people did not choose to listen to Hosea or to Amaz. So now we will look at Joel because Joel is addressed to the southern kingdom of Jerusalem. So coming to the book of Joel, it basically has only three chapters. So chapter one talks about a plague of locusts which will come upon the land.  So maybe we could look at chapter two versus twelve and thirteen. So if someone could read out Joel chapter two, twelve and thirteen. Now therefore says the Lord, turn to me with all your heart, with fasting, with leaping and with mourning. So rend your heart and not your garments return to the Lord, your God, for He is gracious and merciful, slow to anger and of great kindness, and He relents from doing harm. So at this point of time, this was the difference between the northern kingdom and the southern kingdom. Northern kingdom outright idolatry.  They will worship the Canaanite gods. They don't even pretend to be holy. Here on the southern kingdom, the people, they are more hypocritical. They'll pretend to be very, very holy. They'll pretend to be doing all the correct things. So you know, they will have these ceremonies of deep mourning and fasting. They will tear their robes and say, Oh Lord, we are crying out to you for justice and mercy. But inside their heart, there's only dirt, there's only sin. So the Lord in fact says to them over here, rend your heart and not your garments. I'm not interested in torn garments. I'm more interested in your torn heart. Are you willing to tear your heart and say, Lord, I'm ashamed of what I have been doing and I want to change.  That's just outward show. Are you willing to tear your heart and say, I'm going to rip out all the wrong that is there inside. So God says, if you are willing to do that, I can stop this plague of locusts, which is supposed to come upon you. Now the word locust is just another word for grasshopper. So you have different types of grasshoppers, especially there in the Middle Eastern region. They had a wide variety of grasshoppers and so over here, God is speaking metaphorically, is not talking about an actual bunch of grasshoppers. He's talking about a huge army which will come like a huge swarm of locusts. Now, if you were to look at that verses which talk about the locusts, there are four kinds of locusts mentioned in that particular passage. So Joel chapter 1 verses 3 and 4 if someone could read out and count the number of types of locusts which are mentioned. So I'll ask you the question after we read out those two verses, how many types of locusts are being described over there, what are the names given to them? So Joel chapter 1 verses 3 and 4. Tell your children about it, let your children tell their children and their children another generation. What the chewing locusts left, swarming locusts has eaten, what the swarming locusts left, the growling locust has eaten and what the growling locusts left, the consuming locust has eaten. Okay, so this is a prophecy that they should tell their children and those children should tell their children and in that way to the future generations. So here this prophecy is not just a prophecy of judgment for one generation. This is going to be a judgment which is going to come in step by step over a series of generations and the locusts which are being talked about over here, are going to be different kingdoms which will come and attack. So the first locust which is described is the devouring locust. Okay, so different versions will have different wording.  That's basically the locust which will eat up everything that is green. So even if this one leaf left on the tree, it will eat up that leaf. So everything that is green, they will come and eat. So in those days, they were a farming community. Their economy depended upon agriculture. They didn't have industries and all the other things which we have today. So imagine if you have a bunch of locusts coming and attacking the land, their entire economy would be destroyed. There would be no food left. There would be no grains to sell. It will affect them financially in a big way. So locusts were considered a very, very dangerous threat. And so God uses the example of locusts to talk about the judgment which will come and he talks about a specific kind of locust. He talks about the chewing locust which will chew up everything. It will devour everything in sight. It will not leave anything. And so generally it is said that this probably refers to the Babylonians who come and attack the southern kingdom. So they chew up the temple. They chew up the city. The walls of the city are broken. So they basically chew everything that is in sight. Nothing is left. So this is the first kind of judgment which will come upon them. After that you have the second kind of locust which is being mentioned. The word used over there is swarming. Most of the English translations will use that word SWARM. That just basically talks about a whole bunch of locusts which are together. And when you have a whole bunch of locusts together, it's called a swarm of locusts. That's the English term that is used. Just like you have a bee, bees of the beehive. When all the bees come out of the beehive and you have a huge swarm of bees. It almost looks like a small cloud. And if you were to go to YouTube and if you were to type out the words swarming locusts, they would literally show you. You'll see a cloud in the sky moving, a black cloud moving in the sky. Only thing it's not a cloud. It's hundreds of grasshoppers all flying together. It looks like a dark cloud. So in those days, if you saw a black cloud coming towards your town, everyone would start crying out and say locusts are coming and they're going to destroy our fields. Because once the locusts land in your field, they will wipe out every bit of vegetation. Nothing will be left. So swarming locusts were dangerous. They would come like a large cloud. And it's very interesting when you look at the YouTube videos. I mean, they show a person who's standing in the middle of a cloud of locusts and is taking with his camera is literally surrounded by hundreds and hundreds of locusts. So those are your swarming locusts. And so after the Babylonian invasion, the next kingdom which comes and attacks, those would be the Meads and the Persians. They call them the Meadow Persians. So the king who married Esther, he's a Persian. So they were called swarming locusts because it's like a thick cloud. They literally cover the entire land. You can't see the daylight. Once you have this huge, you know, you have millions of locusts coming and they cover the sky over your area. It becomes dark. You can almost cannot see the sunlight. So that is the kind of picture being used over here for the Meads and the Persians because they covered almost the entire world, the known world, you know, which they used to call the people in those days were not aware of some of the continents. But they were aware of Asia and Europe and all of that. So they covered almost the entire area, Meadow Persians, right from Egypt all the way up to Pakistan. That entire region was covered by the Meadow Persians as though, you know, by a swarm of locusts. So that is the second judgment which would come upon the land of Israel. The third kind of locust which is described in some Bibles, they will call it the young locust. In some Bibles, they will call it the crawling locust because I think in the first two months or something, the locusts, they cannot fly. The wings would not have developed. So they only crawl along the ground. And again, you know, you have YouTube videos of this where the entire ground is covered with them. It looks like a moving carpet. You can literally see it moving because they're all crawling, crawling, crawling and going. And you can see every bit of ground covered by them. Now this there, the commentaries compare it to the Greek Empire which will come. And the Greek Empire, they will be able to get into every sphere of life like this crawling locust. Even the smallest gap, they'll get into the gap. They'll not leave even one bit of ground uncovered. The Greeks were like that because you see, they were the ones who were making advances in science. They were the ones who were bringing up new cultural practices. Their language became so popular that everyone began to speak in the Greek language. They were able to spread into every area of society. So they were like the crawling locusts. Then you have the next kingdom being mentioned, which would be the destroying locusts which are the Romans. The Romans were a military power. They were very, very powerful. So they destroyed many of the places which they conquered. So the Lord is telling, tell your children about this. Tell your children's children about this, that this is the kind of judgment which will come upon you. But at any point of time, if you choose to become faithful, if you choose to give up your evil ways, I can stop it. I can stop the locust attack. But if you do not come to me and repent, all these four levels of judgment will take place. So tell this to your children. Maybe they'll be willing to listen. Maybe they will be willing to repent. So that's the message which Joel wanted to convey to the people. So we are told that most probably he would have written his prophecies during the time of Ezra Nehemiah. After the people have come back to the land from exile. So now in this new time, when the people have come back from exile, it's a chance for them to start a new life. To not go back to their old ways. So Joel has commissioned at this time to talk to the people and tell them that if they can live a new and different way of life, then the Babylonian invasion has taken place. But all these other things will not happen to them. God can protect them and shield them from the future attacks. So Joel speaks probably at this point of time, that is when his prophecy maybe was given. He also uses other images, not just the locusts. He also describes the attack of the enemy like lion which is attacking. Maybe in chapter one verse six if you could read out. For a nation has come up against my land strong and without number. His teeth are the teeth of a lion and he has the fans of a fire's lion. So this is another image which is used when you see a pack of lions attacking wild buffalo or something. You have this National Geographic videos where you have a pack of lions, they go and attack the buffalo and they bring it down. And then they show you the animals feeding on the poor buffalo. And then at the end of the video when you see what is left, all you have the ribs of the buffalo and maybe the legs, the hooves, that's it. Every bit of meat is gone.  They will tear apart the prey until nothing is left, till only the bones are left. So that kind of imagery is used in this particular verse to describe the enemy. So God used a whole different types of object lessons and pictures and images and all that to talk to his people. But the hearts of these people had become hard. They had not plowed the ground and made it soft. So that same thing can happen to us. We can listen to sermons every single day. We can go to meetings all the time. We can read Christian books about the teachings of the Bible but the ground is hard. The seeds will not be able to bring out the crop. So we need to make the soil of our hearts soft by digging and removing the stones and the other obstacles which are lying over there in the ground. So Joel talks about these judgments which will come upon them. And then he also goes on to talk about future restoration which God will bring. So Joel, he's the one who prophesies about this very popular thing that we're all familiar with. So maybe we could have someone read out how God will one day restore the people. Joel chapter 2 verses 28 and 29. Joel 2, 28 and 29. And it shall come to pass afterward that I will pour out my spirit on all class.  Your old man shall dreams dreams. Your young man shall see visions. And also on my men servants and on my maid servants I will pour out my spirit in those days. So the Lord speaks judgment but he also starts talking about the new things which he will do in the future. So we know right, Joel chapter 2 verses 28 and 29. They were fulfilled in the book of Acts when the Holy Spirit is given to the people. So the Lord says I will pour out my spirit on all people, not just the people of Israel but all people. So that everyone will start living according to the spirit. So the restoration which Joel talked about has already started from the time of the book of Acts. We see the work of the Holy Spirit taking place in the world. In the book of John, God talks about how once the Holy Spirit comes, he will convict the world of sin, righteousness and judgment. So all that is already happening, there are people from different countries coming to the Lord. There are people accepting salvation from different people groups. So the work of restoration has already started and it will continue till the end times. So there are some interesting prophecies given in the book of Joel regarding this. Maybe we could have someone read out for us Joel chapter 3 verses 9 to 11. Joel 3 9 to 11. Now when you are reading Joel chapter 3 verses 9 to 11, what exactly do you observe over here in verse 10? How is this verse different from what we generally hear in sermons? Is verse 10 saying something which sounds different from what we generally hear? Where it says beat your plowshares into swords, beat your pruning hooks into spears. What do we generally hear? Anyone online, anyone wants to touch upon this? In what way is what Joel saying over here different from what we generally hear? Or have you never heard at all anything about plowshares and pruning hooks? Have any of you ever heard any sermons at all about plowshares and swords and pruning hooks? No, you have not come across sermons like that. Okay, let's look at Isaiah chapter 2 if someone can read out for us verses 3, 4 and 5. Isaiah chapter 2, 3, 4 and 5. Many people shall come and say, come and let us go up the mountain of the Lord to the house of the God of Jacob. He will teach us his ways and we shall walk in his paths. For out of Zion shall go forth the law and the word of the Lord from Jerusalem. He shall judge between the nations and review many people. They shall beat their swords into plowshares and their spears into pruning hooks. Nations shall not lift up swords against nations. Neither shall they learn for any more. O house of Jacob, come and let us walk in the light of the Lord. What is the difference between the Joel passage which we read? Okay, I mean most of the students are like fast asleep.  What is the difference between Joel and the Isaiah passage? Joel passage was Joel 3 verse 9 to 11. Isaiah passage is Isaiah chapter 2 verses 3 to 5. Anyone who's alert, can you point out the difference between the Joel passage and the Isaiah passage? What does it say regarding the plowshares and the spears and the pruning hooks? Exactly, like Akhil who's wide awake and paying attention says that you have the reverse being mentioned. Usually in our sermons, we talk about how our day will come when the Lord will say, take all your swords and other military equipment and turn it into agricultural implements because war is not going to be there anymore. There will be peace. So, you will not even need any military equipment anymore. So, take all your military equipment and turn it into agricultural implements. Turn it into plowshares so that you can dig the ground. Turn it into pruning hooks which you can use for cultivation. That is the passage, the Isaiah passage which is generally preached about how a day will come when war and violence will cease. Just like Sanjay pointed out over here in the online class. So, war will be removed, peace will be established and then you can have agriculture happening in peaceful environment. But in Joel, you have the exact opposite being mentioned.  And over there, the exact opposite is being instructed. The Lord says, take all your agricultural implements and turn it into military weapons because war is coming and you will have to fight. Okay, so hopefully actually some of you are awake now. There's a contrast. Joel is talking about one time period. Isaiah is talking about a different time period. So, what is being spoken about over here? In the Joel passage, most probably it's referring to the final war when all the nations, they want to turn against God and they want to fight against him. So, it's probably talking about the battle of Armageddon. God will say, all of you want to rebel against me, all of you want to fight against me, fine, come. Convert all your agricultural implements into weapons. Come, come and fight. So, the Lord says, there are two, in the Joel passage, it says come and gives one instruction. In the Isaiah passage, also it says come and it gives a different instruction. So, in the Joel passage, the Lord is speaking to the nations and he says in Joel 3 verse 11, come quickly all your nations from every side and assemble, bring down your warriors because God says, I'm ready. You want to fight with me? Let's fight. And you know, the Lord is saying, I will win the battle.  On the other hand, the Isaiah passage takes place after the battle of Armageddon. War is now finished. God has established himself as righteous victor. He is on the throne. The millennium rule of Christ is going to begin. It's going to be a time of peace. And now at that time, you're not going to be needing any military weapons anymore because the battle is now over. So, now over here in Isaiah passage, when the Lord says come, he doesn't say come for war. He says, in Isaiah chapter 2 verse 3, come, let us go up to the mountain of the Lord to worship. And again, there's a come in verse 5 where the Lord says, come descendants of Jacob. Let us walk in the light of the Lord. So, now the darkness is removed, the war is over. The Lord has established his throne and now there is going to be only light. So, you have a contrast between the Joel passage and the Isaiah passage because Joel is talking about that final war between good and evil, between the Lord and all these rebellious nations. And Isaiah is talking about the time of peace which will come after the battle of Armageddon. So, Joel is the one who talks about this and he also makes another promise. In Joel chapter 3 verse 18, we have something else which is mentioned. If someone can read out for us, Joel 3 verse 18. And it will come to pass in that day that the mountains shall drip with new wine, the hills shall flow with milk and all the brooks of Judah shall be flooded with water. A fountain shall flow from the house of the Lord and water of the valley of Echesias. It says the fountain will flow out of the Lord's house. Now, what does this remind us of? Which book of the Bible talks about that? Which talks about, you know, prosperity and then it talks about a fountain which is flowing from the Lord's house. Anyone online? Does it remind us of any other Bible passages? Sister Revelation? Exactly. So in Revelation, you basically have a life-giving river flowing out from the Lord's presence. So here in Joel chapter 3 verse 18 is talking about how one day all of creation will be renewed, the earth will be restored into a new kind of Eden. In the very beginning, in the book of Genesis, you had a perfect garden of Eden but then after that the fall happens, sin enters the world but then in the end, they will once again be a new Eden established. So these are the positive prophecies that are given at the very end, you know, of the book of Joel. So here in the book of Joel, it is a lesson that is being given to the people who have come back from exile. Now they can have a new chapter, a new beginning in their lives if they wish to and the Lord is giving them, you know, this kind of encouragement and telling them I can stop the judgments. I can give you a different kind of a life if you choose to repent. And he says, stop doing an outward show.  Instead, be willing to tear your heart. Be willing to completely repent and change your ways. So these are the things which are promised in the book of Joel. So unless you have any questions, we can actually conclude. So next class we will have, after Joel and Amos, we'll have Obadiah. So next week we'll have Obadiah onwards. So anyone has any questions? No, all right. So we'll close with a word of prayer then. Lord, we just thank you so much for the things that we could learn today. Help us a lot to be people who are very, very careful to sow seeds of righteousness into the soil of our hearts on a regular basis. We pray a lot that we will not become overconfident when things are going well. We will not stop fearing you and honoring you, but rather we will be people who will continue to do what is good. We will continue to sow righteousness into our lives so that when the time of harvest comes, we will reap the fruit of righteousness. We will reap unfailing love of the Lord. We will reap blessings. So we pray a lot that we will be willing to tear our hearts and not just put on outward shows of holiness so that Lord, you can bless us and you can build our lives. Lord, we see in these books of the Old Testament that the Israelite people refused to listen to your voice and so they suffered. But Lord, we who are living in the New Testament times help us to have a very different response. Unlike those people, we pray a lot that we would be willing to respond and when we respond, we pray, oh Lord, that you would shower us with your blessings and you would bring us into complete peace. Thank you, Lord. In Jesus' name, amen. Amen.


Man, is it just me? I don't know. I just really enjoyed this movie. Hey, what's up guys, it's Josh here. Today I want to do a little movie review on a movie called White Out from 2009. Now, I actually really like Kate Beckinsale as an actress, especially around this underworld time. And there's very few movies that are really, really good that just involve tons and tons of snow in my opinion. And then you look at the rating and the rating is just so bad, so poor. And it's like, ugh, I don't think I could watch it. Very few times has a movie been good with this bad of a rating on IMDb. The biggest problem that people could see and that I would see is the bad CGI. And it pretty much happens when they're in a plane and they're supposed to be going through like a thunderstorm or like a snowstorm. It just is the worst, most obvious CGI. And it's 2009, you know? And I would say most of the problems with this movie are in the editing room. I don't know who edited it. I felt like they didn't even hire an editor and somebody just randomly jumped in because literally I would say all the problems of this movie are in the editing room. You could have gotten around the CGI. You didn't even need to use it. I mean, you could have put people by a window and had it just snowing down. Better to do that than to use bad CGI. And the bad CGI isn't throughout the whole movie. It's just mainly in the plane scenes. And unfortunately that is the opening scene. And I actually watched like a minute or two of the opening and just really turned it off. But once you get past that opening scene and you start seeing Kate Beckinsale in her camp area, to me it was very, very interesting from that point. I felt like the story was pretty grounded and changed at like a pretty good pace. You have this big snowstorm coming into Antarctica and there's this one big last flight out. If you don't take this flight out, you're stuck at the Antarctic base for like six months. So everybody's getting their things ready. And I just felt like it was a nice, everything built and changed at a nice pace. I really enjoyed it. This movie seems like it's gonna be more of an action adventure movie, but it turns into much more of a mystery style movie. And I watched it kind of expecting it to be an action adventure style movie. To me, I kind of enjoyed the mystery aspect a lot better. Some people said that, oh, it's so obvious who the mystery killer was. I mean, to me I wasn't like trying to figure it out, but there's multiple people in this movie that aren't who they say they are. So I would be really impressed if you pause this movie at 30 minutes, tell me the two people who aren't who they say they are. I don't think you're gonna guess it because there's lots of red herrings. And again, I feel like if you're watching it and like I'm gonna figure this mystery out, like you probably will have considered the bad people in this movie at one point, but just watching it, it was very enjoyable. Mysteries are one of my favorite sub-genres and this kind of turns into a mystery. For some reason I enjoyed the mystery aspect. I'm not gonna say it was the smartest mystery aspect, but I gotta say I really enjoyed it. I really enjoyed the kind of like snow environment. I also saw someone on IMDB that said there's nowhere near enough Antarctic base type movies and I couldn't agree more. The only one I could think of is The Thing, but it's just such an interesting concept and it just has not been explored. Just hearing the concept of this movie made me wanna see it. This movie almost didn't need the R rating. Now I do like the R rating. There was a couple, like I would say maybe jokes, but besides that it really didn't need to be R rated. There is some graphic scenes with some like frostbite and things like that, but it just, in my opinion, it didn't need to be in this movie. This movie almost has like a PG-13 tone because again it feels like this action adventure. It doesn't feel like this like super deathly serious, aggressive movie. It's kind of like this classic action adventure feel. So it almost didn't need to be PG-13, but at the same time, I do like when they hold nothing back. And this movie wasn't the most intense movie in the world, but there was definitely an intense scene in the middle. And this kind of comes into play multiple times in the movie, but there's so much wind and like so intense like traveling between the camps. It's like you have to hold on to this line when you walk from camp to camp. So there's a scene in like the middle where she has to go check something out at the camp and then there's like a bad guy at wherever she's going. And she has to like get back. I thought that scene was super intense. Now they did have another scene later on at the end that was very similar, but that one wasn't as intense for me. But I gotta say that scene for me was super intense. There was some generic scenes in here. The genericness wasn't bad. Maybe it was like five scenes, but I did see a little bit of that. But in my opinion, all the issues with this movie were in the editing room and just the flow of the movie. The finale too, that what happens to the final conclusion of the main bad person in here, it just wasn't as dramatic as it could have been. The flow of the movie was a little bit off and those CGI scenes just absolutely really killed it. For me, I really enjoyed this movie. If it was by Trier Pass, I would say a solid try. If I was gonna rate it out of 10, I'd probably rate it like a 7.5. If you took out those CGI scenes and took out a couple of those generic scenes, this movie could have been a solid 8.5. Maybe up to a nine if you make the mystery a little bit better, get the CGI scenes out. I mean, I really like Kate Beckinsale and I really liked this whole idea. So anyways, guys, this movie was well worth watching and I liked it way more than I should have. To me, this is a buy. For you guys, I would recommend just a try.  I don't know why they did it. 2009, they should have had better CGI or just not used it. I totally get you. But I gotta be honest with you guys, I just really enjoyed this movie. I can't tell you why. I see why everybody hates it, but I don't know why they hate it so much. Man, is it just me? I don't know. I just really enjoyed this movie to throw on. It is summertime right now when I'm shooting this movie. Like it's the middle of July. So it's the absolute worst time to watch this movie, I guess. But I really enjoyed it. So let me know what you think of Wide Out from 2009, an interesting kind of action adventure thriller set in the deep cold. I gotta say, I enjoyed it, although I do see all the issues people had with it. So anyways guys, we're on the road to 50,000 subscribers and I couldn't do without any of you guys. I hope you guys are the best. Having a great day out here. Hopefully having a great day at home. See you all in the next video. Peace.


I cannot believe that I finally have this in my hands. It's Good Girl by Carolina Herrera. And this Carolina Herrera perfume has been on my radar since I started discovering perfumes. So first of all, of course, the shoe bottle, who doesn't, who isn't attracted to this? I don't think that there's anybody who would walk past this and not be interested in it. And that is what happened with me. I was walking past something in Debenhams, and I saw this, and I had to stop and I asked the lady if I could test it. Yeah, and she's pristed on a piece of paper for me, all socially distanced. And I got to try it. And I tried the Supreme and the Laguerre as well. And it was, oh, I would have all three of them, basically. So I decided to start by getting this one. And this is my first eBay purchase. I'd never put anything on for eBay. But I thought I'd try. And it's come. I felt fairly confident that I'd be able to distinguish between any fakes, because I've tried the original, and I have the samples of the original that I got from Debenhams. So in terms of the notes, this has got almond, coffee, beigament, and lemon as the top notes. Middle notes, you've got tuberose, jasmine, sandbag, oryx, orange blossom, and Bulgarian rose. And then the base notes, tonka bean, cacao, vanilla, praline, sandalwood, amber, musk, cashew, or wood, patchouli, cinnamon, and cedars. So it's got a lot of stuff going on. And when I did read the notes profile after I tried it, I, it kind of made sense at the same time, because I couldn't quite distinguish what it was that I liked about it. And that's just because this is one of those things where it's quite difficult for you to pick out, for me anyway, to pick out any particular one cent. But it's like the combination of all of those creases, really lovely, lovely scent. OK, so I'm just going to spray it on a paper and just revisit my memory. So I've never actually tried spraying this from the bottle.  So OK, definitely not spraying my eye there, because that's where the thing is. I think. Do that. Is that right? How do you do this? I think I need to find a video that shows you how to use the Carolina Herrero spray bottle. OK, I don't think it's got a lid or anything like that. Kind of feels like I should be holding it like this. Oh, there we go. Oh, there we go. We got a squirt out. Oh, there it is. There it is. Got that clean smell. So for me, this smells very, very clean, very lovely, very florally, and it stays forever on my skin. So that's another reason why I wanted to buy it, because when I was using the sample, it was easily lasting about 12 hours at least. It's not like an outstanding perfume. It just smells lovely. Even my husband really loves it. And he he gets easily offended by smells. He doesn't like very strong smells, but he thinks that this smells very lovely and I feel very feminine in it. And I don't know whether it's because of the bottle itself, but I just I like it. I think out of the two flankers, I like the Good Girl Supreme more than the Leger. So I'll definitely be getting the Supreme and the Leger, but I'm so happy to be having this. And for me, this one, I can see myself wearing this basically every day. I don't feel like I couldn't wear this when I'm hanging around the house, when I'm wearing my sweats or whatever, because it doesn't I think it's lovely. And I think I could wear it just as much as when I'm wearing my pencil skirt and my Pussy Bowl blouse and I'm in business and I've got meetings to go to or something like that. But yeah, lovely. I'm so happy to finally have this. This is part of my perfume wardrobe. This is part of my own forever perfume wardrobe. And I'm going to be super precious about it. But yeah, thank you so much for watching. Yeah, click hit that subscribe button and smash the like and join along on the mad perfume journey of a mom of five who's just become obsessed with perfumes. Oh my gosh, I love this bottle. I don't think you can ever get this bottle out of my hands now. Thank you. Bye.


Suspended local government chairman, the executives, councilors and other appointees across the 23 local government areas of Benwick State have vowed to enforce their reinstatement should Governor Heissenthalier fail to obey court judgments, stressing that any attempt to resist them will be met with force. They disclosed this shortly after the burial ceremony of Honourable John Georgie, a councilor representing Igorov, a council ward of Boko, who died in a motor accident along a Makurdi Boko Road while returning from a protest in Makurdi over their long suspension from office by the Governor. Well, we are giving them time for consultations within their party guarantee and they have done that. But if we discover that they just want to strangle it, I think we are going to use the carol sticks approach. We are going to go into our offices through a kind of enforcement of the judgment. We know the right right to follow. We will go through the enforcement of the judgment and that day, if somebody that wants to swap the efforts are taken, there will be anarchy in the local government. It is worth a half to achieve. It's my encouragement. I cannot just dump and go because my colleagues right next to me have died. So let me just quit. No. I am not. I will stay for sure till the end because if I died, let me just tell you that 276, two have left. That's stayed 274. We are pleading with the Governor, even if it is a claim, that he should grant us that opportunity to go back to offices and complete this mandate that our people ask to go and work for them. Look at the situation now. We have started dying and we will not stop crying until justice is done. That's just the fact.


Live from Barcelona, Spain, it's theCUBE. Covering Cisco Live Europe, brought to you by Cisco and its ecosystem partners. Hello everyone, welcome back to theCUBE's live coverage here in Barcelona, Spain for Cisco Live Europe 2019. I'm John Furrier, my co-host Stu Miniman, our next guest is Sergeant Gupta, Senior Vice President of Product Management for Cisco's Enterprise Networking Business. It's the crown jewels of Cisco. Sergeant got the keys to the kingdom, runs product management, so we'll get all the info from you. Thanks for joining us. Good to see you again, keep up the night. Yes, thanks. Thanks for coming on. I know you got a keynote at 12, coming up shortly, but thanks for spending the time. He'll get right to it. Networking is being reinvented. David Geckler said that on stage yesterday in the keynote. It's not changing, it's just shaping differently for customer needs. Intent-based networking, we talked briefly last year at Cisco Live in North America, moving up the stack. It's here, intent-based networking, cloud connections, IoT, all kinds of edge, connectivity. Everything's connected now onto the network. This is real. This is real. And John, look, it's been really exciting, right? We've gone through an 18-month journey here. When we first introduced intent-based networking, we talked about moving away from CLI box-by-box to really solving the problem at an abstracted, intent layer. Specify what user groups and what segments you want, what experience you want to deliver for those applications, and then the network feeding the data back up so you can learn from it, you can manage it, you can troubleshoot it in a much, much simpler way. We're now into this, as I said, 18 months. We have thousands of customers already using intent-based networking. We talked about software-defined access for automated segmentation in the campus, talked about assurance, and then we've been adding capability along the way. And just this week, David Geckler had people on stage who talked about more innovations with intent-based networking in the data center, with ACI Anywhere, with innovations in Hyperflex. Liz came on and talked about IoT and how that fits into the framework. And then Gordon talked about what we're doing with SD-WAN, really, really exciting stuff going on there. Well, I want you to take a minute, quickly explain for the folks watching. I want to get us on the record so we can get definition. What is intent-based networking? What does it mean? What's the impact for the customers? What is it? Intent-based networking means that you can now express your business intent. Here's the outcome I'm looking for from the infrastructure. The system and the architecture will convert that, automatically provision all the underlying components, get the data and the context back out, and prove to you that the intent you wanted was delivered. And what is changing now more than ever? Because applications are coming on. We see DevNet, we're in the DevNet zone. You're seeing a lot of activity, developers. Yeah, so now you've got networks that are programmable. Instead of individual devices that you have to learn from the ground up, all their bells and whistles, you can now live at that intent layer, at an API layer on top of the controllers, and move much more quickly. You can now start thinking about multiple domains on how you cross those domains. What is the big product change, if any? That's actually software is key to all this. This is hard, we've got plenty of hardware. We mentioned Liz and IoT. Still runs router, she takes that software, she packages up, we interviewed yesterday, she was talking about the synergies between the code bases and what she customizes for the IoT market. Then you've got the intent-based networking. What's the product look like? What's the products as they get more horizontal? Yes, so make the mistake, the hardware is still very important. Silicon, A6, very important. But the magic now is in the software layer. So it starts with the operating system, and Liz talked about how we now have the Cisco iOS XE operating system, which is modular, hot-patchable, API-driven, programmable, and now runs across the entire portfolio. It runs on her regularized IoT infrastructure, runs on our switches, runs on the wireless controller, runs on the routers and the SD-WAN edge nodes, virtual and physical, same operating system. And then there's the controller layer on top of that. So for the campus, you've got DNA Center, Cisco DNA Center, and then for the WAN, you've got Cisco Viptela V Managed Solution that provides that controller layer for automation, for analytics on top of the infrastructure. Yeah, Sachin, I wonder if we can help unpack that SD-WAN piece a bit, because WAN's been around a long time. I think back to the 90s, you know, WAN was something that helped us get the internet. In the 2000s, there was WAN optimization. I worked on a lot of replication solutions. I'm not sure that people understand the connection between SD-WAN and really enabling the multi-cloud world that we need today and the portfolio that Cisco has to attract that. That's a great question, you mentioned the 90s. I joined Cisco in 97, and I actually worked in WAN technical support. So I've been with WAN for a very long time. And this is not a, the customers aren't waking up and saying, hey, I need a new WAN. That's not how the conversation starts. What's happening is it's a business transformation question. The companies, the customers are using infrastructure as a service, AWS services. They're using Azure, they're using Google Cloud Platform. They're using all the SaaS products, WebEx from Cisco, right? They're using Office 365. They're using all of these new applications and their data is now not sitting in the data center. I mean, as we announced this week, the data center moves to where your data is. Well, now, if your data isn't in a data center that's conveniently connected through a WAN connection, and it's all over the place, it's in the cloud, in many clouds, you have to think about how do you get traffic in and out? How do you deliver security? And in this world where you may be using internet connections and all kinds of connections, how do you deliver the right application experience? And then, oh, by the way, how do you manage all of this? That's what SD-WAN is about. I need to transfer my business as I move applications or consume cloud services. I need to re-architect my WAN and SD-WAN helps me go do that.  They don't control it. And some of that means I can't necessarily put a box that I can dial in to and do this, so I need a software piece that I can put there as part of my overall configuration. Yes, you need a software piece and you need something that scales, something that is cloud-delivered. You can't be going to hundreds or thousands of sites and manually provisioning these for these services. You need to be able to have virtual services. Now, if you're consuming a cloud service, you need your router, your service presence, your SD-WAN presence in the cloud. So, network functions, virtual services become really critical in this world. Just on scale, I've worked with Cisco on a lot of branch solutions over my career. There's lots of different components of scale that these type of solutions play into. Yeah, scale, look, people say, if everything's in the cloud, does a scale requirement go down? Well, you think about it this way, I have 100 sites and I had one or two data centers. Well, now I have the same 100 sites and I have services that are hundreds of services. So I have applications I'm consuming and as I said, infrastructure is a service and I still have some data centers for my legacy applications as well. So the complexity has actually increased. The scale requirement has increased. I need a much better software method, a software-defined method to manage all of this. This is a key point. A lot of inflection points in the industry always have an abstraction layer to abstract away complexities. So you've got two things going on here that are pretty clear. It's more complexity and more scale. So software is the perfect solution to manage that. Is that what you're saying? Software is the perfect solution to manage this and I'll add sort of one more level to that complexity. Because your traffic isn't neatly going from your branch through sort of a lease line or MPLS circuit that you can VPN into data center, it's a more complicated traffic flow. I might be connecting directly to the internet. Security is a huge concern. That's a great point. I was going to ask you the flow question. You have the old expression, follow the money and you'll find your answers. In networking and in this business, follow the traffic. Remember, north, south, east, west, that became a paradigm that helped shape a lot of network architecture. Now you have new traffic patterns. Can you give some color around the new traffic patterns that comes with cloud, comes with edge? It's not just north, south, east, west. It's everywhere. So what's, what's- So new traffic pattern now can be, instead of from the branch to your headquarters to your data center, now the traffic pattern is direct internet access to the SaaS application or go to a regional hub that I have in a co-location facility. Well, in the old world, you had a security stack in your DMZ. So your best firewall, your best IPS solution, all layered in there. Now in this new world with your traffic getting directly those applications and data in the cloud, you have to rethink security. And so what we did is in our SDUN solution, we embed the best Cisco security technology, application firewall, URL filtering, IPS solutions natively in our SDUN software stack. And so you can deploy this across hundreds of branches now. And so you have assurance that the same level of security that you had in your data center can be delivered in a distributed way, in an easy way. And what happens is customers also want to consume cloud security. You know, maybe I don't want to run in my branch. I actually have a SaaS application. I want to use the Cisco umbrella service, right? So this is a secure internet gateway that processes this traffic, make sure things are clean, make sure we are safe, the customers are safe, and we can now integrate with cloud services and our SDUN solution with just one click. How important is this security paradigm you just mentioned? Because there probably will be consequences. We've seen IoT become a talking point around, oh, surface area, more surface area for security breaches. This security paradigm is different. Why is it important and what are the consequences if not followed? If you don't follow this paradigm, I think the risk you run into is that first of all, you will make a compromise on application experience because you're so worried about security. And let me give you an example. Customers may choose, hey, you know what? I'll continue hairpinning all my traffic through my headquarters because I have a rich security stack there and suffering application experience because I'm going this way to get to the cloud asset rather than going directly. And so by enabling that rich security stack to be virtually enabled anywhere you want it, anywhere you need it, we can ensure that you can have the maximum level of security that you need in your architectural design and still get the application experience by selecting the best path for your application. You know, so as you always, it's good business to be in enabling technology. We've seen that. You guys have lived that at Cisco. What is the most important story coming out of Cisco out of this show as you guys move forward that customers and the industry should pay attention to in your opinion? What's the most important story? I think the most important part of the story is intent-based networking and the architectural shift, the reinvention that it's created isn't about any single domain, right? This is happening in the WAN to solve application experience problems, SaaS application experience problems, security problems, automation scale. It's happening in the campus for segmentation, prevent lateral movement of threats. It's happening in the data center with ACI. And the customers want simple outcomes. What they're looking for is users, devices, things connecting to applications and data. Doesn't matter where they sit and ensuring that from a policy-based model they can automate end-to-end and they can get the visibility, the telemetry end-to-end to solve problems and to learn and to improve the network. So cross-domain traffic. Cross-domain. Application programmability of the network. Yes. And the role of data that plays in that seems to be a common thread. Beautifully summarized, John, that's exactly right. Well, what's come up in the keynote? What are you going to talk about here at 12 o'clock this noon tier in Barcelona? Yeah, so on the keynote, look, I'm going to recap why have we done this, right? Why does it matter? Why isn't CLI still going to work for you? And why did we need to reinvent our working? And then talk about the journey so far, all the new things we've announced. And then what I'm really excited about is I have a partner coming on stage with me talking about how we're delivering SD-WAN solutions for our customers, right? And how does that conversation work? What should you really worry about as you select the service, design the architecture you're going to go with?  I remember back in the 90s, multi-vendor was a big word. Multi-vendor meant interoperability. Working with multiple industry standards, stuff. I hear multi-cloud, I get a similar vibe. This seems to be the trend that people want to pay attention to just as much as hybrid cloud or maybe even more on the multi-cloud side. Some analysts are even saying multi-cloud is hotter than hybrid cloud. Do you agree with that? And how does multi-vendor, multi-cloud, Jive, Cisco, you've guys thrived in a multi-vendor world. Take, what's your thoughts on this multi-cloud? I think in both of those situations, customers are looking for freedom. It needs to be open, API driven. I should be able to move my traffic one place to the other, my applications from one place to the other, not feel locked in. And so it's critical to support open protocols, open APIs, and to provide customers that freedom. And SD-WAN actually helps provide that. We're using open protocols, open APIs, but at the same time, if I need to move my service from here to there, and I still need to deliver security, application experience, scale, automation, you can do that. So we provide that freedom to run that application in a multi-cloud environment. One of the things that comes up all the time when we have conversations with the geeks out there, the conferences, it's microservices and containers on one side, then the networking side, it's still latency and cost. We've still got latency issues and cost to move traffic around. Still a dynamic. How are you guys still looking at this? Latency is certainly super important in that we're moving packets around, traffic around. And cost, it's still costful. Is this the concept of data center moving to the applications? How do you guys look at that cost equation and the latency equation? That's still important. Can't change the laws of physics. The cost and latency equation is still really important, but the problem has changed now. As your applications now, your data center is sort of moving into the cloud. Think about Office 365. We still need to help you get the best experience for Office 365 as if you were running an on-prem solution. For that, we need to do things very differently to manage latency, to manage jitter, manage cost overall. So what we've done is we use an API integration with Office 365 to give you 40% better performance for that SaaS application. And we're doing this for many applications. So I think you're right. You're solving for similar things, but now everything's changed on you. Like the applications are in a different place. So you just have to solve them in a fundamentally new way. And it's the traffic patterns really comes down to it. And that's a tell sign of user expectation, user behavior, application behavior. This is the new normal. This is the new normal. Great. What are you excited for looking forward? As you look at your business unit, look at Cisco positioning, Sol, I like the new positioning. Very tight, very good. I like it bridged to the tomorrow, bridged to the future. Kind of makes sense, bridge. I like the double entendre there. But as you look at the portfolio coming together with multi-cloud, what are you excited about? What's... I think, look, and I've heard this from many customers and partners this week as well at Cisco Live. We've been on this journey for many years, right? Building out intent-based networking for each of these domains. And now we've got thousands of customers already using it. But the conversations are going from, hey, why did we need to do this? To, hey, help me perfect my design, and I now need to connect two or three domains together. How do we go do that? So we're now having a richer, more mature next phase conversations. So it's working with our customers to realize that value across all of the domains, from anywhere where their users and things are, to anywhere with their data and applications. And the network is foundational with the security architecture. You can build on that. That's where the magic will happen from your perspective. You see that. That's where the magic will happen. And you know what? Only Cisco can pull this off, right? Because we have leadership in every one of those domains and we're following the same architectural principles across all of them. So if someone said, Satchin, this is not your grandfather's SD-WAN. What do you respond to that? How do you update that narrative? What is the SD-WAN? New message. What's the new picture for SD-WAN? What does that mean? The new SD-WAN is about connecting to your applications and data in any cloud, in a multi-cloud environment. SAS, IS applications, it doesn't matter. And your private data center. Still delivering the best security, best application experience in an automated way at the skill that you need. Data is the center of the value of the project. We've been staying on theCUBE for nine years. Finally, it's happening. A lot of stuff coming together. We're meeting the road. Congratulations on your success and thanks for spending the time to come in. Great to see you. Thank you. Good luck on your keynote. This is theCUBE coverage here live in Barcelona. I'm John Furrier, Stu Miniman. Back with more coverage here from Cisco Live after this short break. Stay with us.


Hello everyone, today I'm going to be lecturing on chisker analysis. We use chisker analysis when you have to deal with categorical variables. As we all know by now, categorical variables fall into different categories or groups. It's like you're classifying data points according to their underlying characteristics. For example, we could have a category of eye color. Under that category, we could have categorical variables like brown, blue, black, green, and so on. Another example can be college admission results. In this case, the two categorical variables would be accepted, hee-hee, or rejected. An applicant either accepted or rejected, not both at the same time. So applicants belong to one of the two categories. It is really important with the categorical variables that they be separate. A data point cannot belong to both at the same time. When we analyze these kinds of categorical variables, we use a different approach from analyzing continuous variables. Now, before we get into the details of chisker analysis, we need to understand some fundamental or important mathematical concepts behind a contingency table. A contingency table which is a matrix or a rectangular array of frequencies in rows and columns as it's showing right now is a table showing frequency counts under different conditions. The word contingent is very similar to dependent or conditional. So the numbers of counts in each cell in a contingency table represents, for example, the number 13 represents the condition under sound sleep, yes. And taking vitamin, yes. So in this example, the first column here represents a participant took vitamin and they had a really good sound sleep.


So we're here to mail it and you have a new PC. Yeah, I know it's in from metal. We have a new PC we call the PC G03 So this is this is Intel Windows computer. Yeah So right now you're running to display. Yes, it's your display with VGA and HDMI. All right So let's do unboxing So it's shipping. It will really start shipping already started shipping. What's the price? With how many GB? 32 mmC. Let's see on the side here. You can see it has Windows 8.1 quad core With 32 GB 2 GB RAM. Okay, let's do unboxing So shipping including shipping all over the world Without shipping so people can pay like something like $20 more to get fast shipping Quick start gap on the box All right. So what kind of connector you have? Oh, so we have we have a VGA HDMI LAN 3 USB and SD card reader. All right So there it is and it can even have a space for storage inside or it's not we'll have this slot, right? So is this table So we can see right here. You're running Windows Windows 8 you can see here. We are official Windows 8.1 license from Microsoft So it's a real license All right real license with the Intel processor, how's the stability is a good performance? It is 4x4, 3x4, 7x5 Right, and you can run any kind of app you want on it even the kind of like set-up box apps, right? Yeah, it is one perfect work with XBMC coding and work perfectly with Popcorn Time So right here For example Popcorn Time, XBMC Popcorn Time is pretty cool app and so it can output HDMI Run all these Firefox all this stuff just table Cool, so this is a set-up box. It's a PC set-up box everything So $149 only one version to GB 32 GB So a little bit lower price if you don't take Windows. Yes. All right. So there it is This is the box Connected right here, and it's real and it's shipping and How's a how's this? response consumers very happy they They you get a lot of demand for it Last two weeks
