Hi, my name is Russell, I'm a librarian at the University of Alabama. This video will show you how to start using Mango languages. Specifically, you will learn how to set up an account, how to navigate the courses, how to use the My Activity feature, and above all, how to use Mango as a tool to accomplish your language learning goals. So what is Mango? Mango Languages is an online program that contains courses for over 70 languages, from German and Portuguese to Pashto and Korean. It provides interactive tools for learning vocabulary, pronunciation, and grammar, all within a culturally responsive framework. Now let's start by opening Mango. On the library's homepage, select the databases link from the quick menu. Locate Mango Languages under M on the A to Z list. When you click on Mango Languages, a login screen appears where you can either enter as a guest or you can log in to your personal account. Because I want Mango to remember my language progress, I'm going to log in to my account. If you do not already have an account, select Sign Up. Mango will ask you what language you want to learn. If you're unsure of your decision, you can always pick other language courses after you create your account. Enter your name, email address, and a customized password and you're all set. Now when you log into Mango, the first thing you see are groups of lessons in your target language. All lessons are organized into theme chapters and each chapter belongs to a certain unit. Now let's say you had a personal goal to learn basic Italian so you could navigate an airport. You can scroll through the different chapters until you find one that matches your criteria. After selecting a chapter, you can pick whichever lesson you want in whatever order. We each have the same conversational and grammar goals. You can take a sneak peek at these goals before embarking on the lessons. We can see here that this chapter does introduce vocabulary and conversational topics about airports, but it also goes over advanced grammar topics as well. With this feature, you can make a decision on whether a particular chapter is above or below your current language proficiency level. If you're not confident about your language skills, you can scroll back up to the earlier chapters. Let's navigate through a lesson. Each lesson focuses on a specific conversation. Mango breaks down these conversations so that you have a chance to practice the vocabulary and learn the pronunciation and grammar tips. In addition, you can toggle through the lesson as quickly or as slowly as you like. There is no mandated time limit. Depending on your language goals, you may be more focused on learning a specific concept or developing reading or listing proficiencies rather than completing an entire unit or course. Because there are no mandatory requirements, you can do just that. Mango gives you that flexibility to self-direct your language learning however you want. Another important feature to know about is my activity. This is where Mango has stored all the data about the courses you have taken, what unit, chapter, or lesson you have completed, how much time you spent on that lesson, and the date and time that lesson was started. It also keeps track of your scores from placement tests and chapter quizzes. By checking these assessment logs, you can see what aspects of your language learning need to be improved. It's a great tool for keeping yourself accountable to your language learning goals. That's all for now. Thanks for watching! If you have further questions on using Mango, you can email me at rtpeterson1atua.edu or visit ask.lib.ua.edu to ask a librarian.


You tell me, with the season on the line against the Oakland A's, hopefully it'll be at Yankee Stadium, you're sure everybody, you're sure that Louis Severino is your starter? I'm not, because right now, if the wild card game was played tomorrow, my starter would either be Jayhap or Tanaka. I would not start Severino in a winner-take-all game. I just wouldn't. And Don, you know this, Severino is one of my favorite pitchers ever. At the beginning of the year, I said he's one of the top five pitchers in baseball. You remember, we kind of talked back and forth about it. That's how much I think of Severino. But you can't tell me that that guy is the same pitcher that I think is awesome. He's not. He hasn't been for 10 or 11 starts. I mean, how can anybody see anything differently? I know. And we'll go back to yesterday's conversation, which I want to ask you about. When you said you ran into Boone and he was very confident and very relaxed and chill about this season. And that when they're healthy, they believe they can beat anybody. Well, not knowing who's going to pitch your wild card game, having a catcher that can't catch, having a third baseman that's defensive liability, that has nothing to do with DD and Judge being out. These are legitimate concerns about this baseball team. And you just lost two out of three to a team that you're likely going to have to face in a one-game playoff. Great that that game will be Yankee Stadium. Maybe. Maybe. But why exactly is there all this confidence when they get healthy? We're talking about major issues with this team that have nothing to do with health. It's a legitimate point. I just think that Boone has an unwavering belief in this team. But here's the problem. As I say at the start of every show, the date of the show, it's getting late early, as Yogi used to say. You can't keep thinking, well, things are going to work themselves out. Even Boone showed a little bit of that after the game. He said, we've got to start playing better. They do have to start playing better. Now they'll get a reinforcement tomorrow. In all likelihood, DD Gregorius gets activated. And then you've got to wait on Chapman. And you've got to wait on Judge. I think that Judge is going to come back. I think that Chapman is going to come back. I think Chapman will come back full bore. We have no idea what Judge is going to come back. That's a serious injury. He's coming back from a broken bone. And he's not going to have the benefit of any kind of rehab games. He's going to have to play simulated games, which is not the same as being on the field. So I think that that's what Boone is thinking. When we're fully loaded, we're beasts. That's what he's thinking. But when your catcher is having a hard time catching the ball and your ace is not pitching it all like an ace. Look at his ERA. Over the last five, six, seven, eight starts, it's not Louis Severino. And I'm not bashing the guy. I'm just making an observation. He is not the pitcher that he was at the beginning of the year. He's not even close to it.  He's not that guy. Now, I don't know what's wrong with him. I don't know if it's fatigue. Everybody insists that it's not an injury, so you have to believe them. But it must be fatigue. He's pitched a lot of innings over the last two years. His fastball doesn't have the hop. The slider does not have the downward drop that it used to have. As an outside observer, there's no way, to me, it's a slam dunk that he would be the starter in the wild card. And then if he is the starter, you really like the combination of him and Sanchez? No. Wow. Now we're one mistake cost to your season.


Tiger Lake has done wonders not only to Dell but to every laptop manufacturer in the world. The CPUs are so much better than their predecessors that the new laptops that came with them appear to be supercharged, performing much better across the board. One laptop that has been enjoying this new performance is the Dell Latitude 155,520. The Latitude brand has been in need of something to boost it up, as they have previously had great features, oriented at corporations, such as the Dell Optimizer and Express Charge. The laptop is also quite cautious to the environment, utilizing up to 21% bioplastics, which is great since we rarely get interested in the way that we have damaged our planet, and finding ways to minimize that damage is certainly helpful, so props to Dell for that. Today we are presenting you with laptop media's top 5 picks about the Dell Latitude 155,520. Dell has been by far the most environmentally friendly laptop manufacturer in the world. And we like that very much. The message of protecting our world should be out there and we for sure hope more manufacturers embrace this as well. The design uses up to 21% of bioplastics for the body of the laptop and while plastic isn't considered durable, the machine is actually pretty solid without any major flexing. The weight and height are greatly reduced, compared to Latitude 5,510, with the new 5,520 weighing 230 grams less, 1.82 kilograms to 1.59 kilograms, and being 1 millimeter thinner, 21 to 22 millimeters to 19.9 millimeters. The lid can't be opened with a single hand, but fortunately, the display has thin side bezels, while the top and bottom ones are quite a bit thicker. After all, at the top, you will meet the HD camera that has a privacy shutter and the optional IR sensor for face recognition. Please remember, it would be of great help to us if you just hit the like button and subscribe to our channel. That would motivate us to make even more and better videos for you. The laptop has ample amounts of upgradeability, offering both RAM and storage expansion. The RAM is upgradable through two Sodom RAM slots, which run in dual channel and can support up to 64 gigabytes of RAM. As for the storage, there are two M.2 PCI-EX4, with the number two slots supporting PCI-E Gen4 drives. If you need additional help to upgrade your RAM or storage, we are leaving our teardown video, which goes in depth on how to safely get access to all of the slots. The laptop comes with a decently wide I.O., which consists of two Thunderbolt 4 connectors on the left. Moving over to the other side, we find the rest, which has a security lock, HDMI and RJ45 connectors, two USB type A3.2, Gen1, ports, a 3.5mm audio jack, and a micro SD card slot. The laptop has a great keyboard as well, which has semi-clicky feedback and fairly long key travel. The keyboard has a dedicated numpad, making it a fully fledged unit. The keyboard is comfortable for long use, and the addition of a backlight is also great for those long nights or any dimly lit environment, in general. The laptop has a beefy 63 watt-hours battery unit, which lasts for 14 hours and 43 minutes of web browsing, and 10 hours and 38 minutes of video playback. As always we perform our battery tests with the Windows Better Performance setting turned on, screen brightness adjusted to 120 nits, and all other programs turned off except for the one we are testing the notebook with. There is a configuration with a smaller 42 watt-hours battery, but we believe that you should go with the larger one. While the keyboard is very comfortable, the touchpad was a miss for us. First of all, the dedicated buttons, which we still think have a place in laptops, are gone. At least, now the size of it is bigger. The signature nipple, which acts as a mini-mouse is also gone, which is sad for a productivity notebook. That, paired with the aforementioned lack of dedicated buttons, makes for a less comfortable experience when using the touchpad.


All right, good morning. As people come in, we will start this second round of keynotes with a very interesting twist, which is how does cloud native impact adjacent areas and technology? So that's the focus of this whole section of keynotes. And you will understand and appreciate how different open source projects within the Linux Foundation are working together to enable this phenomena. What I'm going to talk about today are three things. And I call it the new world of open source networking, edge, and IoT. And this new world has three characteristics. The first one is telecom networks globally have now chosen open source to be their de facto platform. That's number one. Number two, the cloud is moving to the edge. And edge is going to be unified across not just the cloud, but cloud networks, telecom, enterprise, and IoT. It's going to be a common edge. So we'll talk about that built on open source. And number three, there are interdependencies between projects across cloud native and other technologies. So I'm going to cover all three. Let me start off with the telecom networking part. Open source is going to be the de facto way how global networks are built. Why do we know that? The journey started with SDN and NFV several years ago. I was one of the first ones in that journey. That journey led to disaggregation, where you had a choice of hardware and software. It moved to automation and orchestration of the entire network zero touch last year. And then this year is about open collaboration with the cloud native and containerization. And to help with this journey, Linux Foundation, Linux Foundation Networking specifically, is very proud to host nine of the top 10 projects, top 10 open source projects. We have operators and end users participating that account for almost 70% of the global mobile subscribers, including the top three from China here, top China Mobile, China Telecom, China Unicom, and all the vendors that are in networking. So this is just the board of LF Networking, but huge momentum here. And that momentum has been recognized through deployments, open sources deployed in some of the largest carriers and specifically projects like ONAP that Jim talked about, open network automation platform which was created through the collaboration of China Mobile and AT&T a couple of years ago and now is the de facto platform, right? Geo, Reliance Geo, the fastest growing LTE network in India is using that AT&T, China Mobile, Bell Canada, Orange, you name it, there's huge focus on deployment. And the thing that I personally like is the how open source is developed. And I call it diversity across people, communities, geographies, and companies. So you can see some of the panels. We had an all-female panel, keynote panel. These are technical leaders in the ONAP community, right? They own the TSC. We had meetups, including last year here in Shanghai. So, and then on the right-hand side, you can see from the colors that various companies are contributing from the first release to the releases afterwards. So it's very important from a diversity perspective. And the focus areas on networking for this year in terms of open source are two things. One is compliance and verification, and the other one is standards and open source harmonization. So let me take two minutes to explain those.  You get a VNF or a virtual network function or a workload or an app, right? Load balancers, firewalls, evolve packet core. You get that from one vendor. You get the orchestrator from another vendor. You get the virtual infrastructure manager from another vendor, and you get the hardware and NFVI that we call it from another one. And then you have to onboard and test. What LF Networking's OVP program that just got launched will do is simplify the whole life cycle by 50%. It will be based on ONAP and OPNFE, and we are working with GSMA to help this standardized NFVI. Huge, huge progress in the community to simplify deployment. The second important thing we are doing in Networking is to make sure that standards and open source work collaboratively. We have white papers that are just refreshed that explain how the communities work, and we are now the showcase for standards and open source collaboration, whether it's MEF, TMF Forum, ORAN, Etsy, GSMA. We are the standard, and we work with them very, very closely. Now, that's the core Networking, which is now automated, and it needs to be automated before 5G hits. Now let's move to the edge. When we move to the edge, today you have a fragmented edge. You have a cloud edge, you have an IoT edge, you have an enterprise edge, and now you have a telco edge. We believe that there needs to be a unified edge, and so we announced in 2019 an umbrella project called LF Edge, which is hugely supported by you folks here in China, that unifies the different edge communities. This was found by five founding members, founding projects, and 60 founding members. Now today we are up to seven, including Baidu's open edge, which is going to be contributed into LF Edge. We're at 70 plus now, and we are working very closely with a lot of standardized community. So this is how edge looks at the landscape. So you can see from the top, you've got to collaborate with ORAN, then you have a project in Home Edge, which is the software that unifies the appliances inside the edge. Then you have Eve, which is the on-prem edge, comes into an Acreno blueprint, which is another project that glues everything together, and then moves into the core, running ONAP. ONAP works with Kubernetes and OpenStack, and then works with all the standards. Looks complex, but it is very, very nicely laid out, okay? And so that brings me to my third and very important point, which is we're not living in the world of isolation. Cloud Native is not on its own. Networking is not on its own. Edge, Blockchain, Cloud Foundry, these are all platforms that are collaborating, and it's very important. So I'm going to give you a few examples here. The first one is LF Networking is working very closely with Kubernetes to figure out how we can do a hybrid migration of VMs or VNFs to CNFs, okay? And CNFs are Cloud Native functions. They have a very specific characteristics, and we want to move them along. How does that happen? We have testbeds. We have ONAP working groups that collaborate, and they will come up with a solution for that, okay? Later on today, we'll have Brian talk about Blockchain, and this technology is extremely relevant to telecom, and we have the telecom SIG that will work closely with the LF Networking. So these are just, and here are the use cases. So these are just examples of projects and umbrellas working together to collaborate and make things happen. And when we make things happen, the stack looks very simple. At the end of the day, end users make money from these services, cloud services, residential services, enterprises services, or IoT AI services. And they run those services on infrastructure, data centers, carrier networks, cloud networks, and public or hybrid or private, doesn't matter. And then the layer in the middle is the plumbing. That's the glue. That needs to be automated, and that's the project focus for LF Networking, Edge, Kubernetes, LF AI, LF Edge, okay? So that's kind of the whole picture. So from my perspective, the key takeaways for this year in 2019, this is the year of collaboration, okay? And in telecom networks, open source has won. There is no more proprietary deployments all the way to RAN. However, there's a lot of innovation on top of the open source plumbing, as I call it. But ONAP is the chosen de facto platform. The Edge is completely fragmented this year, but we are bringing a unified edge together across IoT, telecom, enterprise, and cloud through the LF Edge program. And each of these will have blueprints in the various verticals, like automotive, energy, insurance, banking, et cetera, using several of the technology building blocks, okay? And finally, technologies and industries are extremely dependent on each other. And we will have major collaboration. So if you're in one project, please don't limit yourself to that one. Expand your horizon and come together as a total team. So with that, thank you very much. And I will be also hosting the rest of the session, but thanks for listening to me.


A ribbon cutting was held for the grand opening of a new double quick in Elkhorn City on Thursday, March 21st. It was a pretty exciting day, something that we have looked forward to and anticipated. It's a beautiful, sunshiney day, so thank goodness the good Lord's being good to us on weather. But, you know, we were very anxious to get this Elkhorn City store open, not only because we want to serve the customers of Elkhorn City, but because of what this location means to us. Appalachian Community Care offers outpatient medication-assisted treatment for addiction, counseling and behavioral play therapy for children, accepting Medicare and all major insurance. Recovery is hard, regret is harder. Appalachian Community Care, Pikeville, Whitesburg,<PHONE_NUMBER>. Find them on Facebook. Many turned out to the ribbon cutting to see the new amenities, sample some delicious double quick food, and celebrate with the staff of the beloved gas station chain. This ribbon cutting was special, however, as it opened mere feet away from where Matthew's parents met for their first date. We just am so proud and we hope that this spurs other companies to want to come here and invest in Elkhorn City. The new double quick location is eager to serve the people of Elkhorn City, and they hope more businesses will consider opening locations in the Pike County town. For Mountain Top News, I'm Kelsey Fidell.


Okay, so we're talking about experiments and experimentation and fluid mechanics and we're looking at a technique that makes our experiments more efficient and this technique is referred to, well we'll begin with the theorem, but Buckingham Pi theorem and it's named after Buckingham who developed this in the early 1900s and he came up with Pi parameters and that's why we call it Buckingham Pi. So what we're going to do in this segment is we're going to present the theorem and the methodology behind it and then in the next segment we'll go through the step-by-step procedure and then we'll work some example problems. So what the Buckingham Pi technique does or method is it provides us with a way of finding non-dimensional parameters for a given experiment. We talked about the sphere in the last segment, what Buckingham Pi will enable us to do is determine how the different variables and we talked about force, we talked about velocity, diameter, density and viscosity. How can we combine these together into non-dimensional variables that help us collapse the data and I talked about collapsing data from a Pi parameter one to a Pi parameter two and you might have more than just two Pi parameters but if you could collapse your data into a line or it could be a curve or anything like that, that is good because then that relationship then can characterize many many experiments and as engineers we like having that. So what we're going to do we're going to begin kind of with a generic type of scenario where we have some functional relationship. So imagine we have a scenario where we have a number of parameters and we can have parameter one which we will call our dependent parameter and then the independent parameter is q2 through qn minus one. So let's imagine we have that scenario or we could rewrite that in the following manner so you could write that as another functional relationship yet to be determined. So let's assume that we have a scenario where we have all of these different parameters one through n, one of them is dependent, the others are independent. Looking at the Pi theorem, the Buckingham Pi theorem, so what the Pi theorem says is that our n parameters can be grouped into n minus m independent Pi groups where we could rewrite that function with a new function now. So n was the number of parameters that we had, I haven't defined m yet but I will in a moment, or this could be rewritten with one of our Pi parameters on the left. So we have this relationship that exists now n and m, let's define those. So remember n was characterizing the number of dependent and independent parameters or variables we have and in the example we're looking q1 all the way up to qn and m is the minimum number of dimensions required to characterize those parameters or variables. So by dimensions we mean length, mass, time, temperature if you have non-isothermal scenarios. So we have these functions and the thing that is different from what we're looking at here from this function even. So when we look at this function this had all dimensional variables so that that's, those have dimensions, those have dimensions but when we come to the Pi groupings and so let's look at this one these Pi groupings are all non-dimensional so they all have units of one and and so that's the difference. What we've done is we've collapsed all the variables in our experiment into these Pi groups and so we say that there can be n minus m of these Pi groups so let's take a look at that. Now one thing to note about the Buckingham Pi technique it will not tell us the functional relationship in order to get that we need to conduct experiments. So when we have these non-dimensional Pi groups we will not know the relationship we need to get their relationship from experiments and the other thing is that if you take Pi parameters and combine them together they will not generate a new Pi parameter they need to be independent of one another so let's take a look at that. So if we had Pi groups and we tried to recombine them like this thinking that we're coming up with new Pi groups, Pi 5, Pi 6 were not. Pi 5 and Pi 6 are not independent because they can be formulated by combinations of other non-dimensional Pi groups and consequently we cannot call them new Pi parameters so all Pi groups need to be independent of one another. Okay so what we're talking about here taking a lot of different parameters scaling them down collapsing them into these non-dimensional groups what we will do next is take a look at how to put this all together and we'll look at the technique first and then we'll look at some example problems involving doing Buckingham Pi analysis.


Stand right here Right there Ninja, how you doing? Good good good When I'm in California on an airplane to California for work, so when I'm gone I need Michelangelo and Raphael to protect Mama Michael and the homeland you got to protect the homeland, okay?

Woulda woulda woulda Nope Michelangelo come back with a with a shell and Num chucks help the cause shell Ninja turtle shell Terra power Num chop those are for your nut. Those are for you Michelangelo and Raphael That's yours. You both get a pair Joseph now you got a now you got a shell and you've got num chucks So you guys got to protect the homeland while I'm gone. All right Okay, Ninja Turtles you gotta take care of mama I Got ya.  Can you smell it? It's oxygen Oxygen baby sea level that's what I'm talking about. Oh, I love me some Denver mile-high city But when you get down into that sea level Breathe the air breathe it in it smells so good All right Ramada We're coming for you time for bed 6 30. It's time for bed folks two nights before race is the most important night To get a good night's rest. So here we come Ramada call the vlog here. This is starting year three case. You didn't see yesterday's vlog We surpassed two years straight of daily vlogging meaning I Didn't miss a day. I didn't miss a single day in two years of making a video for you. All right, so that's kind of cool Thanks for inspiring me and I'm watching a little hockey go abs to try and distract my brain from the race in What 36 hours ish? Well when you watch this less than 24 hours?  All right. We're in San Francisco tomorrow. I'm driving an hour and a half north to Lake Sonoma I'm staying in Cloverdale.  So that's nice See beauty work hard Love each other
