Hi, I'm Zor. Welcome to a new Zor education. I would like to expand the previous lecture where I was drawing certain graphs of equations like this. So I would like to expand to basically talk about different set theory manipulations of the graph. What I mean is like union and intersection, these set theory things. So let's consider that your graph should consist of two separate pieces. How can you represent algebraically in this form, basically the equation which represents this combined graph? Or alternatively, if you know that the points of your graph are actually intersection of points which belong to one graph and points which belong to another graph, how to algebraically express this intersection of two graphs. Actually, I did touch this particular point in the previous lecture when I was explaining how to draw the graph of this equation. So I was first talking about like naive dividing by x. So you have y is equal to zero, which is this basically line which coincides with an x-axis. But then since we divide by x, we have to really separately consider the case of x is equal to zero and x is equal to zero is a vertical line. So the combination of these would be this. I would like actually to use exactly the same technique and explain how to do this. Well, basically that was union of two graphs, right? So I will use exactly the same technique to unionize two different graphs. So let's say you have two different functions. Let's start with the functions first, one function and another function. Now this has certain graph and this has certain graph. Well, let's consider that the domain where the functions are defined is the same. How to represent algebraically the union of these two graphs? Well, let's just go back to this example, which I was just mentioning. X, Y is equal to zero. Recall that if you have a product of two different things, which is equal to zero, then either a is equal to zero or b is equal to zero. Both actually result in the whole equation to be true. Now, that means that if I will use y minus f of x and multiply it by y minus g of x and put it equal to zero, consider this particular equation. Now, when is this true? Under what circumstances, what points with coordinates x and y belongs to the graph of this equation? Well, either those points which nullify this part or the points which nullify this part, which means points which satisfy this equation or that equation. So, again, the fact that this is or, these or there. These points or these points. This actually means that we are unionizing all the points which belong to this and unionize with all the points which belong to that. This means that our two graphs, separate graphs, will be unionized when we are represented by this particular equation. In more general case, if instead of this type of functional dependency between x and y, you have an equation dependency. Basically, it's exactly the same thing. So, if you have one particular dependency and you have another dependency, then this is some graph. This is some graph. The combination of these two graphs, which is a union from the set theory point. E is represented by multiplied by f2 xy equals to 0. So, this is how you unionize the graph. Well, apparently everything can be done in an opposite direction. What if your equation actually looks like this in the very beginning? And you are asked to draw the graph of this particular dependency between x and y. Well, you can obviously say, hey, this equation is equal to 0 only if f1 of x and y is equal to 0 or this is your unionization. So, all the points which satisfy f1 is equal to 0. Unionized will all the points of f2 is equal to 0. So, these two equations must actually be represented as graphs and unionized. And this is an easier task to grab these and these separately and unionize than to graph the big thing. Now, from this position, let's go back to our original example, which I was just talking about, x, y equals to 0. Well, this is exactly this case, right? So, x is equal to 0 should be unionized with y is equal to 0. So, x is equal to 0 is vertical line and y is equal to 0 is horizontal line. So, the combination of these gives you the same graph we were talking about. In this case, we came up with the same result using a little bit more general approach to manipulation with graphs. We basically unionized them, all right? Now, okay, union we have covered. Now, let's talk about intersection. Basically, we are using the same trick. I mean, we will find an algebraic equation which is equal to 0 if both parts are equal to 0. So, whenever we are multiplying an equation to 0, then either this or that should be equal to 0. And that's the source to unionization. The formula which will give you one of the formulas, actually there are many others, when we are requiring that both A and B are equal to 0, can be something like this. Now, when is this is equal to 0? Only if both A and B are equal to 0. So, if this represents one particular set of points and this represents another set of points, then this represents an intersection between these two sets of points. Both A and B must be equal to 0. So, if you have a function which looks like, let's say, y minus f of x square plus y minus g of x square equals to 0. What does it mean? What's the graph of this particular equation? Well, obviously, this is a combination. This is supposed to be equal to 0. So all the points which are represented by the function y is equal to f of x must be there first. Then this also must be equal to 0. Which means the second piece is all the points which represent the function y is equal to g of x. But since both of them must be equal to 0, it's only intersection between these two graphs, which would be a graph of this particular equation. So, how to draw something like this? Well, first you draw the left part, then you draw the right part, and then intersect them. And obviously the same thing is true for more general representation f of 1 of xy square plus f2 of xy square equals to 0. So obviously this also is an intersection between this graph, f1 of xy is equal to 0, and this graph, f2 of xy is equal to 0. So that's what it is. Next, what's next? So we have basically, by the way, instead of a square plus b square, I can actually use something else. For instance, let's say absolute value of a plus absolute value of b is equal to 0. Now, again obviously since this is non-negative and this is non-negative. So it's only when it's 0 and this is 0, the total will be 0. But absolute value is sometimes a little bit more difficult to deal with than the square. But that's kind of a personal preference and probably depends on the problem in question. All right, so that's the theory of this. And now let's just do a couple of examples, which will basically illustrate this particular approach. How to draw certain things in certain cases when it's not really obvious, but using this approach we can do it. So I have three examples here. Example number one is x square is equal to y square. What is the graph of this particular equation? Now, if you wish, you can rewrite it as this. Okay, that actually kind of brings up to a very interesting modification. You know that the difference between two squares is this, right?  Now, we remember that if you would like to draw a graph of the product of two functions. Are equal to 0 functions of two arguments x and y. Then it's a union of this union. I will use the sign of union from the set theory and this. So what's the union of these two graphs? What's this particular graph? This particular graph is y is equal to x and this is y is equal to minus x, right? So graphically, y is equal to x is this, y is equal to minus x is this. So the combination of these two lines is a union, right? The combination means union of these two lines is the graph in the original equation. Okay? Now, is it obvious that this is exactly this particular set of two lines? This is bisecting the first and the third quadrant and this is bisecting second and the fourth quadrant. Well, looking at this, I'm not sure it's so obvious that this is really the graph. But if you transform it in this way, it's kind of easy. All right, second example. Okay, second example is y square equals 2x. Okay, I think I was talking that if you have a graph of the function f of x, y is equal to zero and you exchange the x and y places and you will put f of y, x is equal to zero. Then these two graphs will be symmetrical relatively to the main bisector of the main angle of the first and the third quadrant. Because whatever point x, y, let's say this is x and this is y. If it belongs to this graph, then the symmetrical point, so this is y and this is x, belongs to this particular graph. So I was explaining this. From this perspective, the graph of this function should be a symmetrical line to this one, right? And this is the regular parabola. So the regular parabola comes this way and if I will symmetrically reflect it, it will be something like this way. So that's what we will have to really obtain from the considerations of symmetry and this thing. Now, what if I would like to approach it differently? The way I would like to approach this particular graph is not using this symmetrical consideration, but slightly different thing. First of all, let's just consider what's the allowed value for x. Now, since x is equal to y squared, y squared is not negative. It means x is, so graph should be concentrated only for values of x greater or equal to zero. Nothing on the left from the zero is defined. Okay, we still have to define what's on the right. What I can say is the following. y squared minus x is equal to zero and x for positive or zero x I can always represent as this, right? This is x for non-negative x. Same thing, square root and then squared. So that means that I have this or again the difference between two squares is y minus square of x and y plus square of x is equal to zero. And again using our considerations about when this particular function is equal to zero and either this is equal to zero or that is equal to zero. This gives me y is equal to square of x. This gives me minus square root of x. Now you remember that this particular function or if you wish x to the power of one-half is this. We were talking about x to some power. We had the whole lecture how this particular curve looks like for different values of power. So for one-half it looks something like this. Now this one is basically the same, just symmetrical relative to the x axis, right? Whatever positive y, now you should go to a negative y. So it goes this way. So the combination of these two lines gives you the graph of the original function. So we have exactly the same curve which is original parabola, it's symmetrically reflected relative to the bisector. We just came to the same conclusion using slightly different logic. Which is good actually, I mean it's great when we can come to the same solution using different ways to solve the problem, it just confirms that we were right. It's always great when you come to this type of situation. I mean in simple cases like this you probably are sure in the first place that you were right. But in a complicated case if you have more than one approach and you're coming to the same solution that's great. All right, and the third one is, well it looks complicated but believe me freely not, y minus x square square plus absolute value of y minus square root of x to the fourth square equals to zero. Don't get scared. All right, there is a purpose in this. Now first of all this is sum of two squares, right? Now since it's a sum of two squares and it's equal to zero, it means that we're talking about intersection of two graphs. This graph and this graph. So we have to separately consider what's the graph of this? And this is obviously y is equal to x square, right? And that's a regular parabola. And how about this? Well, let's write it this way. Well, if you think about this, for positive x and y, you can just drop the absolute value, right? For y, so it's positive. And on the right, square root of x to the fourth degree is basically x square, right? So for positive or zero, actually, non-negative. You have this, which is the same as this, right? Okay, how to expand it for all other combinations of x and y? Well, first of all, since there is a square root of x, we cannot expand it to the negative x. X must be non-negative, otherwise the square root doesn't exist. Okay, so the function, this particular graph is concentrated only on the right part of the coordinate plate for non-negative x. Now, how about y? Can we expand it to a negative y? Well, obviously, yes, since this is an absolute value, it means that the graph is symmetrical. Whatever is on this side would be symmetrical relative to the x-axis. Because if point x, y belongs, then x minus y also belongs, since y is always in absolute value to the graph. Now, so for non-negative x and y, we have this graph, so it's a parabola. For symmetrical side, we will get this, obviously. So the graph of our function, this function, is a piece of a regular parabola reflected down relatively to the x-axis and we have this particular thing. So that's the graph of this particular function. Well, I shouldn't say function, this is the graph of an equation. This is an equation, so the function. Because again, for a single variable of x, we have two different values of y, so we shouldn't really call it a function. But yes, an equation. Equation of two variables, x and y. Now, let's go back to this one. What's this? Well, this is a regular parabola, which means it goes this way. Coinciding with this in the first quadrant of the coordinate plane. So what's the intersection between these two? So obviously, the intersection is this part. This piece of the parabola, half of the parabola, is actually an intersection between this and this. Well, so this relatively complicated equation can be graphically represented simply as half of the regular parabola. I told you it's simple. All right. That's it for today. This is just a little expansion on certain graphs and manipulation with graphs. There is something else which I would like actually to address, which is polar coordinates. And that will be in the next lecture. Thank you very much.


All right, our first question is from Andrew Kan one.  All right, so I'm gonna reword this question. How do you bulk gain muscle without gaining any extra body fat? All right, so it's virtually possible. Well, here's a couple of things here, okay? Number one, it doesn't take that many extra calories to build muscle. You're not gonna gain muscle anything faster than a couple pounds a month.  But even at three pounds a month, which would be amazing. If you gain three pounds of muscle in a month, that'd be phenomenal. If you did the math on how many calories it took to produce that, it's not much at all. It's like an extra 50 calories a day. So on the one hand, you wanna bulk in a way where you're eating minimal extra calories to build muscle. By the way, you also wanna have a very strong muscle building signal along with that. So you wanna have a good workout program that's telling your body to build muscle. But here's the other side of that, because I know people listening are like, it doesn't work for me. I gotta eat way more calories to build any muscle at all. Well, the reason behind that is because eating extra calories also sends a muscle building signal. Believe it or not, if you bumped your calories by 500 calories above maintenance or even 1,000 above maintenance, if there's an anabolic part to it, right? It does send a muscle building signal. So this is where we get into this kind of gray area. Now, I know you said, Adam, for example, that it's impossible or whatever. If the signal is strong enough, the body will build muscle. And all I have to do is point to studies where men are given injections of testosterone, so they're given steroids, and their body weight oftentimes doesn't change, but they lose fat and build muscle at the same time. Now, of course, they have a very loud hormonal signal, but that just highlights that the signal is the most important thing. If you're really telling your body to build muscle effectively, you're getting good sleep, obviously you're eating healthy, and you're following a workout, this is the most important part, you're following a workout that is appropriately intense, has the appropriate amount of volume, is utilizing the best exercises, you're seeing strength gains. If that is sending a very, very good muscle building signal, it doesn't take that many more calories to build muscle. I think you kind of have to be a black belt to do this, right? And it's really genetic freak. Well, it's less to, and even if you are a genetic freak, it's still the mental discipline that you have to have, because you have to understand that you could very well be building muscle at the perfect rate, and not see the scale move whatsoever.  You don't want to ramp it up. Yeah, or you might even see the scale go down to your point, you could lose body fat.  You're right. But in reality, you could actually be just in per, so the hardest part about this is the mental discipline to just stay the course, to believe that, okay, I've figured this out, I've got enough calories, I know I'm eating well, I've got, I'm following a good program, I'm training consistently, and I'm seeing strength go up, and just staying the course. There's no way around it, like it's gonna, if you were to try to really nail this down, it's gonna take a really long time, and spread out, and really managing your calories at a level that is just barely noticeably in a surplus. Like you just have to very much be meticulous about it, and I just don't know that a lot of people have that kind of discipline. No, I sucked at this for years, right, because I was the skinny kid that wanted to gain weight, and so the scale was so important to me. If the scale went up, well, I'm crushing, and I'm doing a good job, but the reality is that doesn't always tell you everything. So there's a few tips that I'll give you that I think can help a lot, and this is just based on my own experience. Number one, are you getting stronger? Okay, so if your strength is going up, you're definitely not losing muscle, or it's very unlikely that you're losing muscle, and you're probably gaining muscle, or at least going in that direction. So are you getting stronger? Number two, also use either body fat test, or circumference measurements. Now for me, when I gain body fat, it's typically around my waist. So if I measure my waist, I can tell if I'm getting leaner or gaining body fat. If the scale goes up and my waist doesn't go up, it's muscle, or if the scale goes up and my waist goes down, holy cow, I'm doing the holy grail. The only reason why I don't like that one is because of like, inflammation in the gut, water retention, and a lot of things. Yeah, you can't take one measurement to heart. You gotta do it kind of as a friend. I like the body fat one, and if you follow me since the beginning, this is actually how I built my Instagram. So when I came out and I measured my body fat percentage, and it was at 20% body fat, which at that time in my life, I'd never been that high before, I was 212 pounds. And when I showed the journey, I actually, my goal was to stay at 212. And that's where, so when I came all the way down to 7%, I was 212 still. And the goal was to show people that I didn't need to have this huge swing one way or the other. I didn't need to add on 20 pounds of muscle to then lose 30 pounds total of body fat. It was like, I'm gonna hover right around this 212. Now mind you, week to week, I had some 214s, the 211s, and but the goal was to kind of, that my home base was 212. And the way I looked at it was if I ever went, if I started to creep up, I would kind of back off calories a little bit. If I started to really dip down, I would increase a little bit, but I was really trying to stay, because I knew I had plenty of body fat to trim off. I knew that I was consistent with training, which I wasn't before that. I was sending a signal to build muscle. If I could keep my calories at a place, that my body was kind of hovering around that weight, I was training correctly and consistently, and I was eating good, that I'm probably having a nice little exchange. Yeah, and then here's the other part of it too, and this took me a long time to understand, is that building muscle is a slow ass process.  It's probably not all muscle. It's actually probably mostly not muscle. You just, nobody builds muscle that fast, unless it's muscle memory. So unless you were super buff before, and you stop working out, lost a lot of muscle and started working again, or you're like the one in a million or a billion. But muscle building is a slow process. So if you're inching up on the scale, ever so slowly, where every couple months, you go up a couple pounds or a pound and it sticks, and you're getting stronger, and you're noticing in the mirror that you see more definition, you're probably gaining muscle.  I would have never been able to do that as a kid, because I was so impatient. Oh yeah, no, I didn't have the discipline as a kid to do that. I'm glad you brought that up though. What was I just gonna say? You just brought up, no, no, no, no, talking about the muscle memory. So I get tagged on this a lot. So this is a good time to bring this point up. So we get tagged a lot on people that show like these crazy transformations, and people want me to like point out how fake it has to be. And being truthful, they're not always that, some of them are fake. A lot of people Photoshop, a lot of people do that. But for me to come in and accuse somebody and say just because they showed this ridiculous transformation in 60 to 90 days is fake, that's no. If you've been training for as long as we have, I can whip my, I can really make a huge difference. Because of how much muscle I've built over the years, if I let myself really go for like six months and fall out of shape, I can shred body fat and build muscle really quick and show a major change in 60 to 90 days. So those don't always mean that they're fake. It might mean that somebody has been training for a really long time.  They probably were inconsistent.  Yeah, and they just gotta tighten it up and they tighten it up and they actually make a massive change.   I remember my- Stick arm. Yeah, like there was like nothing. My shoulder was non-existent. And I don't remember how it was like a couple of months when I was finally able to work out. And I measured my arm, I lost like two inches or two and a half inches or more in terms of muscle and it didn't look like my arm at all. And it came back so fast. It was literally weeks where it was right back to where it was before. So muscle memory is a real thing. Yeah.


We're back. This is Dave Vellante. We're here in Las Vegas live. We're at .conf, the Splunk user conference. This is the second year for theCUBE at .conf. theCUBE is a live mobile studio. We go out to the events. We extract the signal from the noise. Sanjay Mehta is here. He's the vice president of product marketing at Splunk. He's joined by Manish Kalra, who's the director of product marketing. The big news at the show, one of the pieces of the big news is Splunk 6. It's really targeted at the enterprise. We're going to talk about Splunk 6. We've got a demo. Gentlemen, welcome to theCUBE. Hey, thank you. Thank you. So Sanjay, let's start with you. What are the goals and objectives of Splunk 6? Give us the background. Yeah, so our mission statement at Splunk is, and by the way, thanks for having us and it's really great having you here at the event. Our mission statement for Splunk is to make machine data accessible, usable, and valuable to everyone. And so we are constantly progressing on that mission. And Splunk 6 is really all about how do you take data and put it in the hands of everyone? And so what we've done is we've basically delivered three breakthrough innovations in this product. And together, they are game-changing. And that's not my words. That's the words of our customers. That's from our customers when we've interviewed them and we've spoken to them. They really genuinely believe that these are game-changing features.  And what that does is it really provides the ability to analyze data without writing or learning a query language. Secondly, we have the data model. Again, a concept that's made perhaps well understood. We've implemented it entirely differently. For those of you who know Splunk, it's a late-binding approach. It means it's very, very flexible and essentially enables you to add meaning to underlying raw machine data. Underneath all of that, we have a patent-pending technology called a high-performance analytics store. What that does is it improves the performance of analytics kinds of operations by up to a thousand times. And so we're really excited about what this can deliver for our customers. There's a lot more in the release, by the way, but those are the three things that we're leading with. So this is the holy grail of, I've said, big data. Being able to put analytics in the hands of not just the power analysts, not just the technology geeks, but the everyday line of business users, the CMO, the head of logistics, the salespeople, and the like. And a lot of people are trying to go for it. So you've described sort of three capabilities. It's sort of fast, easy, and flexible. It's really what these deliver. And if you don't have any one of those, you're not going to succeed. Talk about the types of people that are going to be accessing this platform. Yeah, so Splunk's very well used in IT today and by security teams. They'll use Splunk to secure their infrastructure. They'll use it to keep systems running, to troubleshoot issues, and to gain analytics from all of their systems. Now, what we've seen over the last few years is that these analytics are all the insights that are available from machine data are really valuable to business users. If you've got a senior title, to like a CEO or CIO, to lines of business users, because they contain a categorical record of all activity and behavior of customers, of users, of transactions, of all these kinds of things. So we've seen this migration of people in IT taking this information and putting it on the desk of the C-level person or the business user. Now, they're consuming that data. They're looking at it on a dashboard. It's real time. They are looking at reports. They're sent to them via PDF. They can use it on their, look at it on their iPads, iPhones, and on their laptops. Now, what we've done with Splunk 6 is we've enabled them not just to consume and look at the data, but to interact and analyze the data. You'll see that in the demo in a second. And what that means is we're really empowering self-service. So we're enabling them to look at that information, to analyze it and to get insights that are genuinely game-chart.  They get a much richer sense of what's happening in real time using Splunk. So this vision is a promise that's been out there for a long, long time in our industry. When it was called decision support, it was a promise of putting it into the hands of the users and it never materialized, but we're on the cusp today. So let's take a look at Splunk 6 and see why. Okay, great. So for our demonstration today, what we're going to do is we've got a fictional company here called Splunktel. And I'm on the business side of this fictional company. And what we've done is we've launched a new mobile music service. So I'd like to find out what platform our users are downloading the music from and what music is popular because, I mean, I might need to renegotiate my contract with the record label that I'm paying a royalty to. So what we're going to do is let's just start with the familiar experience today. What we have here is the standard search window. Users are very familiar with this, the 1800 or so users at the conference here today. They're used to working in this, in this environment right here, our standard search page. As you can see, what we have is our search bar. I'll type in a search. And I've got this information. Now, as a Splunk administrator or knowledge worker, this is very useful to me. It's very familiar. I'm used to working in this raw machine data format to really get pinpoint that problem. But now I'm paying the the analyst persona, the business user. This does not make any sense to me. So the first concept we've introduced is what Sunja just talked about, as part of our powerful analytics story, is data models. And what data models allow here is they allow me to build this structure, provide a meaningful relationship to that machine data. Instead of seeing this, what I get to see is a data model. And what the data model done is that in our, in a customer's environment, you can have lots of machine data coming from all over the place. But I need to look at something very specific. So what this model is, is that specific, consistent view of that data. Now, what that allows me to do is data models power this new pivot interface. So I'm just going to go in and manipulate this data using the new pivot feature. Now, pivot is something that a lot of people on the business side are very familiar with. If they've been using any type of pivot technology previously, something that Microsoft Excel has had around for the since the year 2000. What it allows me to do now is add fields. I'm going to really quit create a very quick report here. I'm going to come in and look at device names. So what are the mobile devices that people are using for to access my mobile service? Done. I'm going to come in. It's going to load. So I can see there's iPhones, Android devices, iPads. Next I want to see what's the actual artist, the music they're downloading. I'm going to come in and download the artist title. I'm noticing that it's not a drag and drop interface. We're going to get there. It's it's okay. So you've got that. I've got more. I've got more. I almost feel safer though that it's not drag and drop. I'm always messing up my pivot tables. Well, we'll help you there. See what happens. The reason the drag and drop is actually very important is I've got this view. I know someone used an iPhone. They download Bruno Mars. They had about so many downloads. The reason it's not the number is increasing is because we're still going through the data right now we're processing it. But this is a little bit of a messy view. You see iPhone, Android, iPhone, Android, Android. I need a better view of it. So that's where the drag and drop comes in. I'm going to split it by column. I'm going to take this device name and I'm going to bring it over here. And now it's going to restructure that view that makes a little more sense in that information. Now I know by artist's name. Now I know per device now, which is a little more it's better information. So you completely reorganized the data as you would expect it at a pivot table, like you said. Now I'm missing one small thing here. Totals. Very easy to go back in now and say, you know what? Total it. I have very easily using drag and drop using the new pivot interface created a report on my machine data, which is very useful for me now. I can share this report. I can save it to a PDF. But you know what? I'm not done yet because some people like me. I'm a visual person. I like visualizations, pie charts and tables. I can come back here and then look at the data in a very different way by simply just selecting a chart here. Now it's loading. Here's that same information in a different view. Still may not make sense to me. I'm going to come here and stack that. I've done all this in the pivot interface. So just to show you what's going on in the background though is that in the background Splunk Enterprise 6 is actually generating queries. And so what Splunk has done. I did all this via a drag and drop interface in the background. What you can see here is full syntax that was generated. Now as a business user now, I did not need to know any of that information. All I needed to know was how to use a mouse.  Okay. I mean the thing with the thing with this product is everything we do is as philosophically in our product is all late binding or schema on the fly is another way of describing the fact that you put structure on the data at the time you query the data. So what that gives you is an incredible amount of flexibility. So what you want though is flexibility. Normally the penalties performance were delivering flexibility with performance. This product is phenomenally fast. Well I was going to say. That's the thing you noticed. So what's the corpus of data that we're operating on here? Machine data. Yeah I mean is it. Yeah I mean today in Kino we had a couple of terabytes and we were able to in fact, Divani when she did the Kino she was able to show a query which was an aggregate type analytics query running across a billion events in a second. Yeah so it's not the it's not the lightweight demo corpus of data. It's a real data set. We're talking terabytes, billions of events, that kind of thing. And Divani also had a little there was, you had fun on the stage this morning with I guess it was Steven with sort of the traditional interface versus the pivot interface and Divani was consistently outperforming just in terms of the user's ability to get back an answer. Right now some of that might have been her expertise I don't know. Well Steve actually him and his team wrote the search language. So he's probably the expert in the world on our search language and so that's why it was an interesting comparison. But he also wins because as well as writing the search language his team also built the data model, the pivot table. So actually the whole goal of all of this is how do you take this data and put it in the hands of more people. They can analyze and get value from it. It's like the command line interface, right? There's still people out there who love the CLI. They like to get the hands of it. But there's so many more users that could benefit from something like this. So thinking across your 6,000 customers today the vast majority obviously. Well nobody, you're just starting. When do you ship Splunk 6? So ship this morning I've got some great news. We've had 5,000 downloads and it shipped this morning. 5,000 downloads? Yeah, it's phenomenal. I mean people can't wait to get their hands on it. We had over a few hundred beta customers where we actually put a thousand beta downloads and a few hundred beta customers. And they gave us fantastic feedback. Many of them love the features in terms of being able to bridge the divide, in terms of being able to take data that usually is used by IT folks and put it into the hands of business users and really bridge that divide. So they really like that. They like the performance. What we haven't spoken about, which we just don't have time for right now, but there's a lot of features in there for the power user as well. So we've got visual interfaces for managing the products. We've got visual interfaces for managing forwarders, the clustering of Splunk for mission-critical environments. We've got a phenomenal, we've done a lot of work for our developer platform. So we've had a strong platform now for developers for over a year with RESTful APIs and SDKs and Java, JavaScript, C-Sharp, Python, et cetera. And what we've done in this release is delivered what's called a web framework. What that means is as a developer, you can now build and innovate on Splunk, like building any regular web applications. So simple XML, Django, JavaScript again, things like that. So when I think about your total available market, you would think there's many more people out there that are non-customers or non-users, I should say, than users. Both are probably true. So today you have virtually everybody, except for the beta customers on the search interface. How do you expect the adoption of the pivot approach to go? Do you expect, let's pick a number so that you don't have to hold you to a prediction. But 10 years down the road, is the vast majority going to be using this new type of pivot-like interface? I know it'll evolve from where we are now. Or do you see more of a mix? Well, I think for now, what we really want to do is to put this analytics in the hands of more people. And what we find is that our customers themselves are extraordinary in terms of how they innovate on the products. They do some amazing things. I mean, we couldn't have even imagined the kinds of things that they do with Splunk. And so the pivot interface is a step in the right direction for sure. We want to enable them to do more. I think what we have heard from our customers is when they use Splunk, they used to, for example, in a traditional business analytics system, you have to predetermine what questions you want to ask. Then you have to build your system, and then you have to wait for the answers, and then perhaps they might have been the wrong questions. We forgot you. Yeah, then you have to buy a bottle of scotch for the power the guy's going to build the queue. Yeah, and that can take many months. Whereas with Splunk, all of this, what Manish showed you, we did in just minutes, that changes how you ask questions. It changes the kinds of analytics you do with your data. And so I think to answer your question, we don't know where it's going to all end up. I think what we do know, though, is that the machine data is incredibly valuable. We want to put it in the hands of more people. We're going to get fantastic feedback from our customers. We already have, and we can't wait to hear from them some more over the next months and year or so, and then we'll feed all of that into the next version. We've already got some great ideas, and you have to wait for those. But right now, this is in the market as of today, and it's had a great reception. Outstanding. Well, gentlemen, thank you very much for sharing the demo. Good luck. Congratulations on getting it out. I know how much work goes into these things. Thank you. And thanks very much for having us here. So we really appreciate it. Thank you. All right, keep it right there. We're back with our next guest. This is Dave Vellante. John Furrier will be back. We're live from the .conf event here in Las Vegas. We're live at Splunk. We'll be right back.


אני sẽ תראה את עמירות שהייתה של ספרמנטליה ובאודי ספרמנטליה שייתה לספרמנטליה. ואני שאולי תמיד לתת לך מה ספרמנטליה שילה מה פרמנטליה שהיה ולפתרות מה האתרון מגנטיקה. ופעולה ככה, אני אעשה לך איך נשאר את העמירות למרות מופקדים בפשרות על המתלרות של הקבילים, פרטיקולות כבילים בשרות על מה שאנחנו זוכרים. אז אחרתיים סטאבים דברים. תשעות קצתים שאין סלאב בסלחת סמימנטל. ואן הכפי כנת שאחרתיים מביאים פה, התשעה של סלאב היא לל, שעות כנת הפתוחה על סלאב שחרר תשעות קצת פתות richer much smaller than L. We drive a car from one contact to the other and measure the voltage on the other edge at a similar distance, basically it emit a mirror image of the same points to contact measure the voltage. Now, the question is what is the voltage on the lower to contact as a function of the voltage on the upperline? For the standard metal, of course we solve Kirchoff equations and Ohm's law in just For the reason which I cannot produce now, we use the notation capital sigma for the conductivity rather than small sigma, but other than that, it's really trivial, and what you find is, since this distance is much louder than the distance between the two contacts, very little of the current gets to the other side and therefore the voltage between these two contacts will be small, and whatever you have here will be parallel to the voltage between the upper two contacts. Now for a vile semimetal in a magnetic field, magnetic field oriented in the z direction, what we find is that there will be a significant voltage on the lower surface, and it will be anti-parallel to the voltage here. A little bit, some similarity but I think coincidental with what Leonid was talking about yesterday in the context of hydrodynamics. So this is the first experimental setup. Second experimental setup, same story, same slab, but now instead of putting a DC voltage and contacts and so on, we send in radiation from above, electromagnetic radiation, more or less at the microwave range, and ask how much of it is transmitted to the other side. Now again, this distance is L, and for conventional metal, of course, this is a textbook problem, and you solve Maxwell equation, you have Ohm's law, and you find that the transmission goes down exponentially with the thickness, with the characteristic length being the skin depth. What I'm going to argue is that for vile semimetals under magnetic field in the z direction, there will be transmission resonances in which most of the absorption in the metal turns into transmission. So there will be frequencies at which the vile semimetal becomes transparent. This has some similarity to an old effect found many years ago by Mark Asbel, by Karna and by Gantt Marker, still working in the Soviet Union, and in the effect they were talking about, you take a slab of a metal, you radiate, and you get a transmission resonance under conditions at which the frequency of the radiation corresponds to the cyclotone frequency of the electrons under a magnetic field, and the thickness of the slab corresponds to the cyclotone radius. In that case, the magnetic field you should apply perpendicular, so the radiation goes this way, the magnetic field should be perpendicular to the radiation. In the case I'm talking about, as I said, the magnetic field is in the z direction, and so is also the propagation of the radiation. So it has some similarity, but it's a different effect. Now the source of both of these effects is one. It is the conductivity of the vile semimetal, and in particular the fact that the conductivity is non-local in space. Of course, as we know, Omslo tells us that the current at the point R and T is linear in the electric field and point R prime and T prime, so we have a conductivity, and sigma tilde means that we're talking about real space, real time conductivity, a conductivity that's a function of the point where the electric field is R prime, the point where the current is measured R, and the time difference T minus T prime. For a standard metal, this conductivity is pretty much a delta function in space, not quite a delta function, but close to it. For a vile semimetal, as I will explain, this is not the case. Instead what happens is, remember the slab geometry, you put an electric field in one surface, you get a current flowing in the other surface, this is when there is a magnetic field in the z direction. It all depends on that magnetic field. So that's more or less the introduction to what I wanted to say. Now let me step back a few steps and review what vile semimetals are and how is this magnetic field, which I said is crucial to everything, how does it affect them? So we're talking about the three-dimensional lattice, so think about the three-dimensional band structure that has energy that's a function of kx, ky and kz, and wave functions which are functions of kx, ky and kz. Now fix ky. So if you fix ky, you get a two-dimensional system because ky is fixed, so everything is a function only of kx and kz. So for every ky, this two-dimensional system has a chair number c of ky. Now just for concreteness, it's not crucial, but for concreteness, let's think about a system that's globally termed versus symmetric before we put in the magnetic field. Then the chair number as a function of ky must be 0, both for ky equals 0 and for ky equals pi. So here's the chair number as a function of ky, and you see it's 0 here, and of course it's 0 here because it's periodic, and it's 0 here also. Now it may be 0 everywhere. And then there's nothing, it's not a wild semi-metal, but it may be that it's not. It may be that for parts of the ky axis, it will be non-zero. Of course there's time versus symmetry, so if it's positive here, it will be negative here, but in any case, what's important is that it's non-zero. When that happens, this is a wild semi-metal. And this was discovered in a series of works, and I have a more extensive list later. So this is a wild semi-metal. Now here's the longer list. This was studied in the last few years by many people, both theoretically and experimentally, and experimentally people saw mostly with ARPES, the Ben Structure that's characteristic of this, and maybe I should say, if as a function of ky, there are regions where the chair number is non-zero, then there must be transition points to each the chair number changes, and therefore the gap closes. So this cannot be gapped everywhere, and this is why it becomes a semi-metal. Each of these points becomes a diracone or a wild cone, depending who you want to give the credit to. And those cones were seen in ARPES, and also in some transport measurements, and there are various materials where that takes place. Now, I'd like to get to this non-local conductivity. So let's keep on fixing ky as we did before. So now we have these regions of ky where the system has a chair number. So as a function of kx and kz, as a function of x and z, the system is a quantum whole state. And if it's a quantum whole state, it means that it has f states on the surfaces. So for values of ky, for which the chair number is non-zero, there will be surface states, or edge states on the z surfaces at which the gap closes and at which there is chiral motion, like any quantum whole state. However, this will be limited only for those regions of ky for which the chair number is non-zero. So the surface which has a spectrum, the z surface which has a spectrum of ky will have what's been called Fermi arcs. We'll have lines of states in momentum space which start and end. Now they don't really end. What happened is that they penetrate into the bulk, into the third dimension which is not down here. Now, with no magnetic field, they solve the block states and there are constants of motion. The crystal momentum is a constant of motion. But once you put in a magnetic field, the wave vector changes as a function of time according to Newton's second law. So ky will, so the electron will flow along lines of constant energy in momentum space which means if it is on the surface, it will flow along the Fermi arc and it gets to its end. When it gets to its end, it must penetrate into the bulk because there are no more states on the surface. So that gives rise to very interesting cyclotron trajectory. So to see that, let's now think about the bulk. So what happens in the bulk if we have a three-dimensional metal in a magnetic field? In the standard metal, you just separate the x-y direction from the z-direction. You have Landau levels in the x-y plane and plane waves in the z-direction in which motion is not affected by the magnetic field. This cannot happen for a vile semi-metal because as we said, as we put the magnetic field, the electron flows along the Fermi arc and when it gets to the end of the arc, there is no choice but to penetrate into the bulk. So it must be able to penetrate into the bulk and not come back to that point. So this point cannot... must have some... there must be a way for the electron to get into the bulk and not come back. And indeed if you solve the spectrum of the... of a three-dimensional diracone in a magnetic field in the z-direction, you get the following type of spectrum. Each one of these points is a Landau level and this is now the spectrum as a function of kz of the momentum in the third dimension. So each of these curves is a Landau level which disperses as a function of kz. Now the zero energy Landau level, as you see, becomes a chiral state with a motion that's directed in one direction in the z-direction. Of course, this is one end of the Fermi arc. The other end looks just the mirror image and has zero energy Landau level which flows in the opposite direction. So now to understand what happens as a function or to understand how the cycloton orbits look like as we turn on a magnetic field in such a situation, let's think first about this energy. So in this energy, the bulk has only one Landau level you can occupy and as opposed, of course, to what happens here which we will discuss a little bit later. So the Landau level has... the bulk has only one Landau level and it has an upwards-moving state in one end of the Fermi arc and a downwards-moving state excuse me, in the other end of the Fermi arc. So that gives rise to a cycloton orbit that looks the following way. Remember, there's this surface, that surface, and the bulk. If the electron starts on the upper surface, it moves in momentum space along the arc which in real space, like always, means motion in a direction perpendicular to the motion in momentum space but anyway, it's a motion along the surface. By the time the electron gets to the end of the arc it gets to the bulk and flows all the way to the other surface. When it gets to the other surface it moves backwards on the other surface and then back. So the cycloton orbit instead of looking the familiar planar circle that we have in a conventional metal it will have sort of a half a circle on one surface then in the bulk to the other surface and then the other half of a circle. We need another blackboard but you get the idea, I hope. So this is the crucial point. The cycloton orbit has four parts, if you want. One in the upper surface, one in the bulk, one in the lower surface and back in the bulk and then it goes on and on. This is the source of the non-local responses that we now see. Now there's a period to this motion and as you can guess by this structure I outlined the period will have two parts which are in the bulk and two parts which are on the surfaces. In the bulk the time it takes to go from one surface to the other of course depends on thickness if the thickness divided by the velocity of the cone and the time to go on the arc depends on how long the arc is divided by the speed at which divided by k dot the speed at which you go in momentum space which is determined by the low end force. So this was worked out by this a group in Berkeley. So now let's get back to the problem I started with. We have the slab and we'd like either to look at the DC problem or to look at the radiation. In both cases what we need is the conductivity. What we need is the non-local conductivity that comes out in a wireless semi-metalline magnetic field. So to analyze this let's look at this real space, real time conductivity sigma tilde for some time t and for coordinates which are one surface and the other surface and to see that to calculate that basically what it says is we need to apply a pulse or a pulse of an electric field on the upper surface at t equals zero and ask how much current we get at the lower surface at the time t. So to apply the electric field at time zero we apply a vector potential AX which is applied at a thin layer close to the upper surface at time t equals zero should actually be a delta function of t sorry the electric field goes like delta a delta function of t and the application of the vector potential sorry, this is a mistake it's a delta function the application of the vector potential shifts the Fermi surface at the upper surface at time t equals zero and initiates a cycloton motion at the upper surface now as I said before it takes some time but this motion gets to the lower surface so the current at the lower surface after a while it starts at zero and then goes up when the electrons from the upper surface get to the lower one and then it goes down when they start coming back and then it repeats itself in a periodic fashion so this is the conductivity this is the real time conductivity for the non-local one having the electric field in one surface and the current calculated on the other surface and we can substitute that into the ohm's law and substitute ohm's law into Kirchhoff's laws or into Maxwell's equations for the two problems as it's discussed before and when we do that we find that this is the voltage as a function of the z direction in the absence of for the DC experiment in the absence of magnetic field as I said earlier there is no voltage developing on the opposite surface at all in the presence of magnetic field we get a voltage that's anti-parallel and is appreciable compared to the voltage in the upper surface and as I said before there are transmission resonances and the physics of these transmission resonances is there is a cyclotone frequency associated with this motion between the two surfaces if this period commensuates with the period of the radiation it's a little bit like the Aspelkana effect the electron absorbs a photon when it gets to the upper surface and emits it when it gets to the lower surface so this is the the story this is the story for a clean case now what should we worry about that can change the picture so there are a few things I'd like to mention in particular two of them because they are interesting first is impurity scattering so this story was all block equations and block bands and with the application of electric and magnetic field what happens if there is scattering so I'd like to distinguish between two types of scattering scattering within the same diracone or wild cone and scattering between different wild cones let me start with the same wild cone because it's more interesting so imagine that before we talked about the chemical potential being here and then if the chemical potential is here there's nowhere to scatter to within the same diracone now let's imagine that the chemical potential is here so now if you move along this chiral mode that has only a direction in the zid only motion in the up direction only motion upwards in the zid direction now you can scatter to higher lander levels which have motion both up and down now it turns out that there's very little effect to this and I'd like to explain that and the analog which I find illuminating to think about is a chiral quantum whole edge coupled to many chiral wires so let's imagine the following situation imagine that we have a new equals one you have a new equals one quantum whole state here and now this is only new equals one and this is there's an edge mode that flows chirally to the right and now there are you coupled this mode to a set of wires here and to a set of wires here these wires are not chiral the mapping is basically the geometry of the cycloton orbit that I explained unfolded into a line this is motion along the upper surface, this is the fermi arc this is what happens when you enter to the bulk you have now lander levels to scatter to this is the motion in the lower surface where you move along the fermi arc and this is the motion in the bulk on the way back again you have lander levels to scatter to you cannot scatter so far until we talk until we get later you cannot scatter from one well cone to the other but you can scatter to this set of lander levels now you see the reason for the relative insensitivity to this type of disorder think about the quantum whole analog send the current from here it will diffuse its way into these wires back and forth but eventually it must get to here there is no way it can get back because this is chiral mode and these are finite wires so all the current that terminates from here must eventually make it to the right which is to say all the current that starts on the upper surface must eventually get to the lower surface and on so what will happen what can these wires do well they can slow things down they can make the motion slower and we'll talk about this in a second and so the distance, the time distance the time separation between the recurring repetitions of the cyclotron motion get longer and longer and these peaks can be boredom because what the electrons will do they will diffuse in between these wires or in between these Landau levels going part of the way down part of the way up diffusing but eventually going down if this is the direction of this state so these peaks will get boredom now when we think about DC we integrate over DC conductivity implies integrating sigma tilde over all times which means bordering or slowing down make no difference what that okay so the DC effect is not affected because we integrate over this as to the AC effect the slowing down changes the period and a cool estimate tells us that there's a slowing down factor of 2n plus 1 where n is the number of Landau levels and that there's a bordering that limits the number of harmonics of resonance that we can observe but it does not destroy the effect altogether there's no exponential there's nothing that depends exponentially on the thickness divided by the mean free path so this is this type of disorder other troubles to worry about second is issues of phase coherence and the like and those are completely irrelevant this is not a quantum effect this is all semi classical transport this is not troubnik of Daas it's basically cyclotone resonance so there is no exponential suppression with temperature and there is no as I said exponential suppression with mean free path third issue to worry about is scattering between different wild nodes this is trouble just like various effects in graphene and so on once you introduce coupling between different diracons the story is over so there is no protection in the sense of the quantum effect the protection is only to the extent that the sample is thinner than the mean free path for inter node scattering and the last thing I'd like to mention in a minute or two is there's something called chiral anomaly should we worry about that thinking about anomalies I notice that normality is in the eye of the beholder so what is normal or anomalous may depend on your view in this particular case this is the equation known as chiral anomaly and it is the fact that the number of electrons in one node minus the number of that electrons flow from one node to another as you put an electric field that's parallel to a magnetic field it looks very mysterious it's completely trivial if you ask me if you just write it in terms of the current in the z direction as a function of the electric field in the z direction the statement of chiral anomaly is the statement that the current in the z direction goes like one over i omega times the electric field in the z direction forget all the other factors what is important is that the current goes like one over i omega so this is the statement that there is ballistic transport along the z direction which is exactly the statement I was talking about before that as the current enters the bulk as long as you don't have scattering between the two diracons it must get all the way to the other surface in this particular case we don't have we send radiation in the z direction so the electric field is only in the xy plane so the electric field is perpendicular to the magnetic field it has no effect on the ac on the azbel-kanat type phenomenon and the effect on the dc I don't have time to explain is not crucial okay the regime we think of is we're talking about micro frequencies of course we don't want interbent transitions nothing optical and so on and it turns out the thickness you want for the slab is a few microns a few microns ten microns something like that so to summarize what I told you is that there are unique cyclotone orbits that go between the two surfaces of a slab sample of וילסמימטל and they give rise to two interesting transport phenomena one is the fact that you push a current between two contacts here and get opposite voltage or opposite current between these two contacts down here and the other is that you get electromagnetic resonant transmission at frequencies that commensuate with the frequency of the cycloneura orbits and the the other thing I told you about which I'd like to emphasize in the summary is that the intranode scattering is limited in the way it can affect this phenomenon thank you very much


Okay, we're back at theCUBE for a final wrap up for day one at ENC World 2012. This is SiliconANGLE.tv's extensive wall-to-wall coverage of EMC World 2012. It's been a great day. I'm here with my co-host Dave Vellante. Dave, great day, and Stu Miniman from Wikibon is going to help us wrap up the day. Stu's been out on the floor scouring for stories, doing a lot of one-on-ones with a lot of customers and attendees. Are you into Area 51 yet? That secret, we're not allowed to talk about it yet, I'm told, but I think we're gonna have a guest on. We're talking about it on the screens, yeah. Yeah, I know, but they are keeping that kind of under wraps even though, Dave, I hear you've gotten a little insight on it. I don't know. I mean, I don't know what's a secret and what's not anymore. So, Dave, let's wrap up day one here. Okay, we've got a huge day tomorrow. Starting up with the CEO of Violent Memory Systems, Don Bacilli's coming on. Yeah, looking forward to that. Chuck Hollis, Green Space Conference.  San Francisco for the HBase Conference, hbasecon.com. But great day today. We were on stage warming up at Joe Tucci. It was exciting. Yeah, that was terrific. I really enjoyed doing that, John. I think that, you know, hey, we brought the greatness of theCUBE to the main stage at EMC World. We collaborated with EMC TV. I was very happy about that. You know, it's a lot of great feedback from the EMC TV crew, because they're just really up there professionals in their photography, their documentaries, and they see the independent analysis and that, you know, I think we're at a historic point where the collaboration between an independent media company like SiliconANGLE, Wikibon, and EMC, where authentically the content is being shared and that knowledge and that experience is really resonating. So I'm excited to work with EMC TV and it was great to be up there and to see Pat Gelsinger and Joe Tucci deliver some great keynotes. Again, we've had a great day of guests here. The theme here is all about agility of IT and big data. Big data, not so much, you know, proof points yet. I think tomorrow will be a different conversation, but today it was all about cloud, cloud IT for agile within the private hybrid cloud environment for, you know, IT enterprises and the service providers, getting that real cloud solution around hybrid. So, you know, that was key. The other thing that I walked away with today, Dave, was the fact that the data protection is really a massive area that is going to categorically, I think, explode. And I think it's been kind of on a neutral set, a set level. The phone's going off, hold on. Yeah, I think you're right about that, John. I mean, I think data protection is a very fundamental, we see it on the Wikibon surveys, it's one of the top three issues that people are dealing with. Backup's always been a big pain point for IT practitioners, and that's now evolving into data protection around security and cloud and big data. The thing about data protection right now is that my point that I have, my observation is, the big investment that EMC made in data domain and Avamar, mainly data domain, because it was a huge brawl with NetApp to win that billion dollar, two billion, two point five billion dollars. It's going to pay off for them now because as the market moves to this virtualizing infrastructure, back up is a little bit, it's very complex, but the demand is high because of, with cloud, which is basically as we heard from Secret CTO, an outsource model. So again, that was a big point. I want to make a follow-up point on that. I had said to BJ Jenkins that I thought it was a defensive move. After the acquisition, somebody at EMC told me, you know what, this was all about, not just defensive, that's true, but it was about growth. I said, that's kind of interesting, but now we've seen that take shape, haven't we, that where data domain is kicked in, they've rationalized the whole Avamar versus data domain thing, and it's growing like crazy, one of the fastest growing parts of their business. I think to me that's the go-to market on that, this new product line is the fact that they have flexibility. EMC's reputation in data backup and data protection, backup and recovery, whatever you want to call data protection now, is the classification of that sector, is that ultimately they are a market leader, 66% market share in a huge market, but the fact is that flexibility for customer choice is critical, and it's hard to say that, hard to be a data backup vendor, Dave, and say I'm going to offer them flexibility and choice. Now the other thing too, I think I took away today, is Flash, right, they just bought Extreme IO, the EMC was first with Enterprise Flash Drives, they announced, Pat Gelsinger on theCUBE last year said, we fell a little bit behind, we're going to do something about that, they announced VF Cash, they announced Thunder, they go-to-market strong, then they buy Extreme IO. I still think there's some confusion as to what the strategy is, I mean I think they've got individual efforts that are good, but I think there still needs to be more work to come together now, so having said that, I think they're ahead of the other big whales, I think there's still some innovation going on in the ecosystem and with Stardust. We've heard from customers directly, we had Secret CTO on here, which is another great segment we'll talk about in a minute, but at Sapphire and other shows we've done theCUBE, we've heard from customers directly where they're putting Flash in front of it's a sand solution, so I think EMC will do quick deployments of Flash, kind of stopgap that either loss of sales and or customer re-architecture, but ultimately I think EMC doesn't know what to do yet because with VMware, where do you put the data layer? Now Pat Gelsinger said today in his keynote that the data layer is going to be decoupled from the app and the apps were tied to the infrastructure, so we're hearing that Pat Gelsinger's talking about gravity of data, so I think what's going to happen is you're going to see a data layer emerge and VMware will be a big part of that conversation. So Stu, what are you seeing on the show?  So, Interest, we talked about EMC and its acquisitions and trying to kind of pull them all together, so one of the things we saw a few years ago is the show had almost fragmented into pieces. You have the people that kind of love data domain, you have the documentum track, you've got the labs people and people are breaking out of their silos and cross-training, talked to a bunch of people that are doing infrastructure for today and tomorrow, and then going to see the data science stuff on Wednesday, so really kind of a mixing of roles and responsibilities and understanding a lot of the different pieces here. The thing we've talked about a lot, Dave, is really the transformation of the workforce and you just can't be a storage guy worrying about your lunch, you need to kind of get out of that silo, work with your peers and EMC were kind of raising themselves to a higher level of discussion with the C-suite to make themselves more strategic. How about the relationship with Cisco? We had Mike Leica on today, Brocade, we saw the V-specs announcement. I mean, EMC and Cisco obviously have a very close relationship, but is it cool and off a little bit? So interesting point, if you look, networkings growing here, Juniper and Arista are both here with good presence at EMC, which is a first. So absolutely, it's always been Brocade and Cisco and starting to see the other networking guys. So we know that these big players have to be able to support multiple environments. I think that the Cisco-EMC relationship is still strong, VCE is here. Cisco was very a key part on the V-specs launch, Brocade was too, but Cisco has a strong presence there. So first place you walk into the part of the billion, Cisco's right there, VCE is right behind it. Giant V-specs bus with Cisco is one of the main logos. So I don't think it's cooling off, but EMC, if they want to stay strategic, needs to keep their options. What do you think about VMAX? We've heard from Secret CTO that good props on VMAX, what are you hearing on that? What's your analysis there? Symmetrics, which has turned into the VMAX, has been the flagship product of EMC for, gosh last, since 1990. So it is still a major part of the portfolio. General feedback we hear from the community is still solid on VMAX. Latest research that the Wikibon group has done still shows its market leadership in its space and it's still doing well. The high end storage isn't as sexy anymore and you're not getting talked about, but EMC is still plugging up. It's interesting, John. Symmetrics, VMAX, it's hardened microcode, been around for a long time, very, very stable. People run their businesses on it. However, that type of ingrained architecture, that hardened architecture is always hard to change. Somehow the VMAX people, the VMAX engineers have been able, the software guys have been able to keep pace with that. Which is amazing to me because you juxtapose VMAX to say three-par. Now, three-par is putting forth the notion in their messaging that, hey, we're the new tier one. Multi-tenancy, fully virtualized architecture, much more flexible. We can support applications across the portfolio more cloud-like. That's the new tier one definition. EMC in the other hand is saying, no, tier one is the traditional high-end mainframe class, reliability, availability, serviceability. So there's an interesting little war going on between the Donatelli acquisition of three-par, HP really going after that high-end base. And EMC doing a great job of holding on to its existing base. I'm interested to see how that thing shakes out. I don't know if you have an opinion on it. Yeah, so Dave, absolutely. When I look at it, it's very tough to kind of go head-on in that space. So tier one vendor, EMC's been there with IBM and Hitachi for a long time. Three-par's got a great product and they're trying to fight EMC in that space. But if you look at the biggest disruptor for large block environment, it's flash technologies and scale-out file architectures. So EMC, of course, with the VF cache and ExtremeIO acquisitions are trying to go in that space. And Icelon seems to be growing pretty well too. So those are, I think, the bigger risk for eroding the Symmetrix market, the VMAX market. John, I wonder if you could give us your perspective.  You're going to the HBase conference, which is the heart of big data. Now you got a big data, data science summit going on here. What do you think about all this? About what EMC's positioning in the market? Yeah, specifically their positioning in big data. Well, I mean, first of all, I just want to say to the audience out there that siliconangle.com and siliconangle.tv and Wikibon will go wherever the stories are. So we're here at EMC, we're up for three days wall to wall, but if there's a story to be had, we will go to the story. And that's why I'm going to San Francisco tomorrow to go to the HBase conference because that's where the action is right now in the data science developer community. And so I think obviously I'm pretty bullish on big data, as you know, but EMC's perspective on big data a little bit different. It's really much more of a business discussion. They talk speeds and fees with Greenpoint a little bit here. They bought Pivotal Labs. So they're putting their toe on the water relative to quote what I call real technical chops when it comes to big data. And so I think they've done a great job with the messaging and they know they're doing work there. So they got their investing in that.  Relative to the data science summit, I think the positioning is clear that they are definitely not going after the developers right now. They are clearly going after the business audience, Dave, where they want to educate them kind of a thought leadership summit. It's kind of a TED videos kind of provocative content. Yeah, they might talk speeds and feeds here and there but for the most part it's mostly high level. What is data science? Kind of data science 101. So I think for EMC, my critique on EMC right now is they are really, really not there with real messaging and real deliverables to attract hardcore developers in big data and that is the alpha developers. Pivotal is a good start and I think that's a great direction. It's not that they're missing it they just don't have anything right now to talk about that. So John, just a question for you on that because I think we saw EMC at Node.js that the Node summit, I see a lot of puppet people here and there is a pretty good data science crowd, people in partnerships. So I just kind of want your opinion on that. Oh yeah, I mean EMC is a huge install base of your startup. Why wouldn't you want a water ski behind EMC's ecosystem? But EMC is a company relative to delivering real value around the technical side on the developer. Just not there, it's the reverse. So yeah, you're right. Pop it and those guys are coming here because there's real challenges in configuration management and automation relative to this legacy platform and it's kind of kluji right now. I mean, green plums evolving but I'm not dissing EMC. I'm just saying this is what it is. The reality is is that EMC is not viewed as a leader in the developer community around big data. On the business side, they've got all the right things in place from the solution standpoint. They got the executives focused on it but you got a conference like HBase conference going on. That's a significant ecosystem. It's the open source. EMC was late to the party in that. We covered it last year at EMC. We asked Pat Gelsinger. We played nicely in the community. They are. I don't think it's just a timing issue for EMC. I'm just saying for this show, compare and contrast, you've got data science summit. I mean, it's a marketing vehicle. It's not open to any real there there from a developer perspective. So we heard the same critique about Strata. Much more suits and Hadoop world this year with Hortonworks is going to be much more developer focused. So the market's growing. There's constituents all around and that's just what it is. Thanks. So EMC made an acquisition today of Syncplicity. Okay. I don't know if you know much about the company but they are a file management system for the cloud and it allows you to sort of sync and share automatically. It's like an iCloud, sort of product. I don't know what they paid but the news just broke about an hour ago. So trying to get some more information. Is it official release by EMC? EMC acquires Syncplicity, yep. Privately held next generation cloud-based Sync and share file management provider. So I guess box-like Sync. There's enterprise capabilities unlike consumer focused competitors. So it's enterprise capabilities. EMC further enables the enterprise to balance productivity for the users, blah, blah, blah. So EMC up three and a quarter percentage today announced is acquired privately held Syncplicity, a leader in cloud-based file management solutions based in Menlo Park. It looks like a security compliance product. That's nice. That fits right at the data protection as we talked about earlier today. This is really a Dropbox type of competitor as well but it's Dropbox for the enterprise. I mean, here's the thing what's going on. This might, I mean, I haven't read it yet but it's just quickly browsing the release. There's a big trend obviously, bring your phone to work kind of thing. Bring your own phone concept. And that's really pushing the envelope on the edge. So we talked about the edge too. You got security. So obviously network policy, stuff that's been around the industry. It's always been great on a firewall-based system. Here's your BlackBerry controlled phone. Here's your apps that are running up. But now with cloud, the consumerization of IT, there are issues around compliance, security, and that's a big trend. What's your angle on that? So interesting thing I took away from the keynote today is I didn't hear a lot about VMware, which is surprising because we've been coming to the show for many years and VMware's been front and center for the last few years. The acquisition sounds a lot like Project Goftopus that VMware is working on. Well, I'm interested in where it fits. They've got 35,000 users.  Is Merits scheduled to show up here?  I mean, I think you're making up a good point, Stu. I think it's an unmuted VMware message there. I didn't hear much. I mean, the big challenge, you know, I've seen with VMware is the shift from kind of the infrastructure to the cloud because those really are two separate product lines from VMware and the solution sets and the people that are deploying them are different. I think what I want to see VMware tell me and I want to hear this from them and I haven't figured it out yet, but I want to see where they put the data layer. So, relative to their stack, where does the data layer fit and is there one data layer or are there mainly multiple data layers? So, John MacArthur's texting me, giving me some good information here. He's the one who shared with me 35,000 users. They've got a native iPhone app which essentially backs up Google Docs. So, that's a sort of interesting, interesting angle. I guess so. I thought Google backed up my Google Docs, but maybe not well enough. My Google's a little flaky sometimes. Recover from tape. Yeah, recover from tape. I wonder what the secret CTO would say to that. Oh no, wait, so not backup, sorry. So, backup, maybe it's an alternative to Google Docs. Really sorry, yeah, because you're synchronizing, sharing files, so it's collaboration and various Dropbox like. So, Stu, what are you hearing? You've been out scouring the landscape today out here at EMC World, attending the keynotes. Share point. What are you hearing on the floor? First of all, it's a big crowd. It heard 13,000 to 15,000 people. It's noticeably larger than last year. We've seen a number of the shows this year cutting back a little bit. So, good crowd. People are really excited to put hands on. Jeremy Burton has put a lot of bling. There's definitely a lot of flash to EMC who traditionally was kind of the East Coast more engineering driven company. Now EMC has a lot more of a West Coast vibe. We love that about Jeremy. Absolutely, so, you know. I want to come back to that. So, actually I'm reading this press release. So, Rick Devanuti is the guy who's quoted in the press release. So, this is an IIG move. Okay, so you basically have got SharePoint, right? Which essentially is part of that whole workflow capability, so that's really where it's going to sit. So, this is designed to really try to bring IIG, I guess, to the cloud. Give them a little bit more sizzle, right? The old documented piece. That division's never really performed the way that EMC has wanted it to perform. So, maybe they're seeing an opportunity to become more box-like for the enterprise. Dave, what's your take on today? I'm about to just get your angle on today. Well, I thought, again, John, we've seen the evolution of messaging at EMC. I mean, I have to say, Jeremy Burton, props go out.  He was very new. And he said, I'm big on messaging. Well, boy, is he ever. And I think the messaging continues to be very strong. The transformation of IT and business and yourself. Transformation of IT being cloud. Business being big data and self being, you know, these other capabilities that EMC services, training is bringing in. So, that's good. I like that messaging. You know, just to add to that, what I've noticed a little nuance with Jeremy Burton's messaging is that, like he did on the first three years ago, he did say that, but look at how it's evolved. CloudBee's big data, did a little nuances. Now it's CloudBee's big data, but he's separating cloud to IT and big data to be business transformation. So, it's transformation message, but he segmented out categorically both. So, it was a nice extension to the messaging and a nice nuance there for Jeremy. I think the other thing I would put out, again, we keep seeing that both transformation and the evolution of EMC. And what strikes me is the strength of the partnership between EMC and SAP, much stronger than it was a year ago. You saw that come to a sapphire. Joe, too, I should mention that on my social cam. Joe, too, should you mention that on your social cam? As well, we know about this project inside of EMC called Propel. It's a very large SAP instance. You know, I think what's happening, the EMC has not come out and said this, but I think that, you know, EMC is a big Oracle shop. And you got to believe that like every Oracle customer, they basically had it with Oracle's tactics. And so, reducing their reliance on Oracle, increasing their commitment to SAP, putting their money where their mouth is, that kind of deal happens at the top levels. When you mentioned Bill McDermott, you could see on your social cam, which people should watch. Tucci just lit up. Oh, we know, we know him at Germany. He's a very good partner, very good partner of ours. So, I mean, I think that that to me is the big new partnership. I mean, obviously EMC and Cisco, but I mean, it's lost a little bit of its shine. You got, you know, some alternatives coming out. We sort of seen that take shape. And now SAP is a new big part. Take Joe Tucci, for example, right? Joe Tucci, a competitive guy, baseball player, as we know.  But Bill McDermott, competitor, right? So Bill McDermott, when we had our one on one of them last week, I like to win. He's a competitive guy, likes to play hoop, Joe Tucci. I could see them getting along, Dave. And I think that's an interesting observation. And I'd be curious to follow that. And I've been noticing configuration-wise, I'm bumping into a lot more people at EMC that work at SAP in a way that you'd almost realize, are they, are you an employee of SAP? So it's very VCE-like. Yeah. I'm just saying. Now, is there something there? VCE, obviously, on Quack has been on about VCE. They're having a compelence on tomorrow? Compelence. Hey, I just got another text from MacArthur, said, True Ventures put in, and some private investors put in 2.35 million last, I don't know, sorry, in October 2008. Never seen any mention of a B round. So that's a couple years ago. But they did raise more money. True Ventures, John Callahan's company? Yeah, so that was probably an exit north of 100 million. Why don't I text them right now? Yeah, see what you can find out there. So that's, you know, the flash thing starting to come together, I mean, I said this in theCUBE today with Mark Sorenson and Barry Ader, it was a good segment that essentially, people say, well, EMC's behind. Pat Gelsinger said they're behind. Now, they're behind, they were behind guys like Fusion I.O., who's sort of leading the space. Violent memories, you know, solid fire, even though I haven't announced the product, has great vision. EMC is ahead of the other whales in flash. So in a way, they're not behind, because if you're huge and ahead of your biggest competition, then you're ahead. And I think they're actually significantly ahead. Now, we'll see what happens. It's a game of leapfrog. We'll see what happens with IBM. We'll see what happens with HP. Is it called Syncplicity? Syncplicity, yes. Syncplicity. So we'll see that game of leapfrog.  They just made an acquisition of Extreme I.O. I would expect, Stu, you're going to start to see some other acquisitions. Just like when IBM bought Neteza, EMC got, bought Green Plum, you had a run on those data warehouses. And the scale out architectures like Isilon and iBrix and all that kind of moves. Yep, they all went. And I would think that you're going to start to see some flash moves. I think HP's got to make a move there. I think this is a great move for John Callahan's firm, True Ventures, because True Ventures just had a great exit with Cetus to VMware, which the VCs were not happy about letting go. They sold it for much lower than what they could have got if they stayed alone from what I heard from multiple sources. But the entrepreneurs really wanted to join VMware, Stu. I mean, I talked to them at the big data party at Ravi's house, and they're like, we love VMware. They love Merits. They love that culture. So a lot of cool deals going on. A lot of M&A action. We have calls into our sources to try to find out how much that went for. But again, all the actors happening in tech. And Dave, like I said on the EMC TV show, IT is back. IT is exciting. The consumer market, Facebook, Twitter is getting played out. Consumerization of IT is where the action is. The VCs are investing a ton of M&A opportunity. And Stu, that's why I think the developers are gravitating towards EMC because EMC is a whale that's creating a massive thermal of opportunity around it. So startups go where the money is and EMC is blazing a trail, Dave, right to where the dollars are. And that's the big accounts. And John, you've been covering the EMC Ventures, which is kind of an interesting arm of EMC, throwing some money around. Oh yeah, and Pat Gelsinger recently been more and actively involved in that by a new manager in place, ex-Intel capital guy running it. So Pat Gelsinger, Intel capital executive running VMC Ventures, ecosystem development. We talked about this two years ago at VMworld. It's an ecosystem. Wintel is the old model. VMware EMC is the new model. So they added VCE and SAP. You can't help but be impressed with the EMC. I mean, not only the messaging, the great marketing. People love to criticize the products, but we have Secret CTO, who generally was- He wanted to grill them. He was critical, saying, what do you say? I got to hand it to VMAX. He was honest. He wasn't just grinding. This is a product, it gets called legacy. It gets called all these pejoratives, but here's Secret CTO, nobody knows who he is. And like you said, he wants to grind them and he says, well, I got to say that VMAX is pretty good. So I say, I get criticized a lot, but I mean, you look at EMC, great marketing, great messaging, fantastic execution. They throw off cash, they make great acquisitions. Company solid, Joe Tucci said on my social cam, lot to do, it's fun. He wants to stay around. It's an exciting time for EMC. They really transform themselves from a storage vendor to an absolute player and also a leader. I mean, they're also leading. So you've got BRS, the data domain acquisition, the data protection, 66% market share. All their 100% of their products hit 100% of their customers, as we've heard from the Secret CTO. So EMC, great field sales force, great consulting organization under Howard Elias, Tony Colas' organization, we'll hear from him tomorrow. EMC's pumping on all cylinders, it's been fantastic. Yeah, and just like I said earlier, I think services is like the secret weapon that the EMC never talks about that much. I mean, they talk about their services, but they don't hear Tucci standing up saying, we got the best service in this, because he doesn't want to tick off his services partners. They really play that partnership game very well. The way they played Cisco, and I say played Cisco, but played nice with Cisco, VC, they got that whole coalition going. Cisco went off and did FlexPod with NetApp, but there's a nice balancing act that they got and they brokeade in really savvy, now SAP, about how they manage their partnerships. Oracle, you know it's this, but what do they do? They pay the million bucks they get on stage in Oracle Open World in front of 15, 20,000 Oracle customers to get their messaging across. It's well worth it. That's a million dollar messaging, and you know that, yeah, well worth it. So EMC's doing great. We are here at theCUBE, SiliconANGLE.tv's coverage. All the signal here are extracting and sharing that with you. This is day one, coming to a close. SiliconANGLE.tv, we have EMC day two tomorrow, wall to wall, Dave and Stu will be covering it with Jeff Kelly and the team. Marcus and Hopkins, Kian will be here with Alex Wilcox is our new guy here. Thanks to the guys for this great day and we'll see you guys tomorrow. And I will be in San Francisco for the HBASE conference. So look for that on SiliconANGLE channel two. So we now have the two channels, look for that SiliconANGLE one will be EMC world, channel two will be HBASE conference. And again, we will go to wherever the stories are. This action, we will bring it to you. This is SiliconANGLE, day one wrap up. Good night and see you tomorrow.


Felly, mae'n gofio'n meddwl y dyddwch yn ydw i'ch awrgwymon hwyl yn ysgolwyddiant yn ysgolwyr-dwych yn y ailul. Mae'r gweithio'r gweithio yn ystafell ar y cyflwwyr hwn o'ch meddwl. Mae'r ystafell y gallai y modd blwyr, osyn i'r gweithio'r arbwy y cyflwyr. I fe ydych chi'n ysgolwyr hynny, phobl ychydig, This will be the only way you'll be able to submit a new article for publishing on Wikipedia's Live Space for the first four days of your new account. What it does, it will submit your article for review by another experienced Wikipedia editor and they'll decide if it needs extra work or if you go into the Live Space. But that only happens for the first four days. After the four days you can publish direct to Wikipedia's Live Space yourself as long as you've made ten edits to Wikipedia, first of all. If you've drafted your article in your sandbox then it's likely that you will have already accrued those ten edits anyway. You can submit your draft for review, that's an option, but the preferred way of doing it if you want to just move it directly into Wikipedia's Live Space is to use the more drop down menu there next to the search bar and there's an option there to move your article. OK, so you'll see that at the moment it's opened up this box that says move page and it's saying that at the moment the page is in the user space area of Wikipedia with this title. So I'm going to change that to article space and change this to the article I'm writing about. So you want the title of the page to be exactly as you want it to appear, so if it's a person's name you must have a capital letter and you must also check that no similar page exists first of all with the same name but if it does you should disambiguate it with a little extra information that will make it more unique and then a reason why you're moving the page well created new article would be that. OK, and you can tick this box to say that you want to be notified of any changes and watch any changes to the source page, your original page and the target page where you're moving your page into the live Wikipedia and then just by clicking that blue button that's all it does it will move that article into Wikipedia's main space and here's one I made earlier and there it is in Wikipedia's live space so if I click that now I would create another page with a slightly different title but that's what it would look like and at that point we would add categories at the bottom and hot cat can help with that and we can also create a talk page for the page and we can include templates as to which wiki projects should be notified that there is a new article on their field of interest and if you're not sure what templates to use have a look at another article on Wikipedia because all it is is just a little bit of text with two squiggly brackets either side but you can check other articles to see which templates they use to see which ones will be appropriate for your article. The one template that you should put on the new articles template is that this is a new user article so you want other Wikipedia to see that you are a new user that you're a new user they should offer help and guidance if need be so there we go a little smiley face now that's probably a good way to end cheers


One of my favorite things about computer science is the world of creativity. My classes right now, we are building what I would call Atari games, very basic games that kind of get students interested. It's moving once it gets back to 100, just so you know that. Maybe not everybody's going to be a programmer, but everybody will have an opportunity to sit at the table with a programmer. Regardless of what field they go into, computer science is going to help them open those doors. One of the greatest things about Kevin is his commitment to diversity, equity, and inclusion. You have issues that you're trying to tackle. Kevin's one of the people you want on your team, he doesn't say, I can't do that. You don't hear Kevin say that. We got Sophie, four of Mario. Girls Who Code adds to me bringing equity to computer science. The goal is to over-represent those groups that are underrepresented in computer science. As a minority myself, and not having many outside opportunities of Girls Who Code to be able to learn STEM for years, it's a big advantage to people like us. So welcome everybody, it is Computer Science Education Week. Last night they had a night of code where families came in, there was over 200 people here. And Girls Who Code decided to sponsor the event. Girls Are In Charge basically, I facilitate the event. I think these nights are important to come together as a Keystone Oaks family, let's code together. And I think he has pretty much made it his goal to open it up to everybody for them to come in. You have a night, a family night where you bring all those people together. Now you have a system in place where the kids start coding in kindergarten and it's so exciting to see five-year-olds, six-year-olds, seven-year-olds, knowing that they're going to continue to grow over the next seven, eight years. By the time they get to high school, they break walls. And I feel like if my work impact other people throughout the state, throughout the country, my children will have a place that's more comfortable for them where they can grow. I want to be a teacher because my daddy's a teacher too, and he's a good teacher. I just think he wants to succeed. He was like that in football. He was like that in the middle school. It's just a drive within him. I certainly would hope that most teachers could see Kevin's commitment to what he does and Kevin's commitment to his students. I grew up without a father. Mr. Gallagher was, you know, a huge inspiration and a father figure to me. When I first had him, I would always be late to class. But he found out what made me tick and what made me think and he never really gave up on me. If it wasn't for him, I probably would have never graduated high school. Each one of those has five values averaged. It's a graph of an average. I see kids who may have been struggling start to succeed. I see the kids that succeed start to excel to other levels that they never thought of. That's your paycheck. That's where it really makes you feel like you made the right decision, that you're in the right field and that you continue to make a difference over your whole career.


What has it been like to do such a quick transition, this two-week turnaround is quite unusual for a mayoral transition here in Boston? I will say that her transition team really has hit the ground running with a high level of energy, excitement, engagement. I don't know when they sleep but because I get emails all the time but they are so activated. And I will say that even, obviously she was very invested going to each community during the campaigning and that actually remains a strong suit of, and I hope it will continue to be a part of her administration. And over the next few weeks, what are the transition teams plans for Mayor Wu's first couple of weeks in office? Right, so it's just, you know, I think continuing to engage the community, making sure that people understand that there's this mandate for systemic change and it won't happen overnight. But that focus on community collaboration and input will continue, should continue. We'll, you know, as advisors have continued to highly recommend that that level of engagement continues and it seems to be the case. I do know though that Mayor left Wu's stance throughout her campaign and prior to that in her city council days where that we, you know, fix the large problems by focusing on the smaller ones. And so, you know, while we're thinking about the systemic changes that you need to happen, I do think that it will also be thinking about smaller things that really do need to get fixed and she has highlighted that as a priority as well.
