Namaste welcome to the session design of multiplexer tree at the end of this session students will be able to design a multiplexer tree in this session we are going to design a multiplexer tree now before proceeding further take a pause here and recall what do you mean by multiplexer so multiplexer is a combinational circuit which selects binary information from 2 raise to n number of input lines using n number of selection or also known as a control inputs and directs it to the single output line multiplexer is also known as data selector now let us see block diagram of n is to 1 multiplexer so where you can see there are 2 raise to n data inputs and where n number of select or control inputs are there and 1 output data line so from this block diagram we can observe that there are 2 raise to n data inputs n number of control inputs are also known as select inputs and 1 data output line now let us see advantages of multiplexer using multiplexer it is easy to design a combinational circuit because whenever you are designing a combinational circuit sometimes it is required to minimize the equation of the combinational circuit using k-map or other technique but whenever we are designing a combinational circuit using multiplexer there is no need to minimize the logical equation it is also easy to debug a circuit which is designed using multiplexer now disadvantage of multiplexer is that if number of inputs are more to a combinational circuit then circuit becomes very large if designed using multiplexer now let us design a multiplexer circuit for example we are going to design a 4 is to 1 multiplexer before drawing a block diagram so we need to know how many inputs are there from number of inputs we can find out number of select inputs required so according to the equation 2 raise to m is equal to n where m is number of select inputs and n is number of data inputs so if number of inputs are 4 then select inputs required that is m is 2 so for n is equal to 4 data inputs we require m is equal to 2 select inputs so let us draw the block diagram here so here the data inputs are represented by letter i so 4 inputs are i0 i1 i2 i3 and let us consider letter s for select inputs as s1 and s0 along with these inputs we have one more input that is enable input denoted as e which is used to start or stop the operation of multiplexer and then we have one output represented as f now the second step is to write a truth table so we know that for 4 is to 1 multiplexer we have 2 select inputs or control inputs as s1 and s0 and 4 data inputs as i0 i1 i2 i3 f as the output and e as a enable input so for this block diagram we have this truth table where we have indicated enable input as active i so whenever enable input is 0 none of the input is get selected or are disabled so we are getting output f as 0 so when enable input is 1 now let us consider 4 inputs i0 i1 i2 i3 maybe 0 or 1 as binary inputs are given and consider enable input as 1 so when select input s1 and s0 are 0 0 then i0 will be get selected so i0 may be 0 or 1 so accordingly output will also 0 or 1 so whenever s1 and s0 are 0 i0 will be get selected and that is connected to the output so output may be 0 or 1 when s1 is 0 and s0 is 1 then i1 should get selected and according to the i1 value whether it may be 0 or 1 we are getting output as 0 or 1 so here only i1 is get selected and that is connected to the output now similarly when s1 and s0 are 1 0 respectively then i2 is get selected and then it is connected to output line when s1 and s0 both are 1 1 then i3 is get selected and depending upon value of i3 output will be 0 or 1 so whenever both are 1 1 we are getting output selected from the i3 now after truth table we are writing logical equation for 4 is to 1 multiplexer so from this truth table we can observe that we are getting i0 selected when both s1 and s0 are 0 0 so here equation becomes i0 into s1 bar s0 bar plus i1 is get selected when s1 is 0 and s0 is 1 so here the equation becomes i1 s1 bar s0 plus i2 is get selected when s1 is 1 and s0 is 0 so i2 s1 s0 bar plus i3 will be get selected here when s1 and s0 both are 1 1 so equation becomes i3 s1 s2 and in a ball is 1 so into e so this is logical equation for 4 is to 1 multiplexer the next step we are going to draw logic circuit for 4 is to 1 multiplexer so here you can observe the circuit is drawn according to the equation now let us design multiplexer tree so what is the multiplexer tree a larger multiplexer can be implemented using a tree of smaller multipliers so when we are designing 4 is to 1 multiplexer using 2 is to 1 multiplexer we require 3 2 is to 1 multiplexer and we require 2 select inputs let us see how so here you can see in the first row we have 2 multiplexers which are having 2 inputs each and output of these first 2 2 multiplexers are given to third 2 is to 1 multiplexers as a input so here you can see the first multiplexer having i0 i1 input second 2 is to 1 multiplexer having i2 i3 input and third 2 is to 1 multiplexer having input which are the output from the first to 2 is to 1 multiplexers so first to 2 is to 1 multiplexer having common select input as s0 and third one having select input or control input as s1 now let us see how it works now let us consider s1 and s0 both are 0 0 where s1 is msb so when s0 is 0 so i0 and i2 will be get selected and as s1 is 0 first input of the third 2 is to 1 multiplexer it get selected so in this way i0 is get selected and that is connected to the output line now when s1 is 0 and s0 is 1 as s0 is 1 i1 and i3 are get selected and as s1 is 0 the first input of 2 is to 1 multiplexer is get selected so here i1 is get selected and that is connected to the output where i3 is not selected now when s1 is 1 and s0 is 0 then because of s0 is 0 i0 and i2 is get selected and as s1 is 1 the second input of 2 is to 1 multiplexer it get selected so here you can observe that i2 is get selected and that is connected to the output line now when s1 and s0 are both 1 1 because of s0 is 1 i1 and i3 will be get selected and as s1 is 1 the second input of third 2 is to 1 multiplexer is get selected so in this way i3 is get selected and that is connected to the output line so in this way multiplexer tree works so let us have one more example 16 is to 1 multiplexer using 4 is to 1 multiplexer so in this case we require 5 numbers of 4 is to 1 multiplexer and in 16 is to 1 multiplexer we require 4 select inputs as s1 s0 s2 s3 and 16 inputs as i0 to i15 and f is the output so here is the block diagram where you can see we have used 4 4 is to 1 multiplexer in the first row where it is having 16 inputs i0 to i15 and in the first row 4 is to 1 multiplexer are having 2 select inputs common as s1 and s0 fifth 4 is to 1 multiplexer where it is having select input as s1 and s2 so in this way you can design any multiplexer tree using smaller multiplexers these are references thank you


Hey there YouTube! What's happening guys? Thanks for tuning back into the channel today right here with the Rust Belt Mechanic. Now I know yesterday everybody on the channel was kind of expecting a video for the announcement of the winner for my 20k giveaway. For those of you who didn't know, I was giving away a Snap-On Ethos Edge Scan Tool. So what I was going to do, I went ahead and I did the drawing. Everybody that got put into it, there was 57 different people with over 213 entries put into the actual contest based on the rules that I gave. So everyone had quite a few entries into it and I am feeling absolutely awesome that there were so many people that were involved in that one and I thank you very, very much. Well we did the drawing and I really wanted to get the winner involved in on like a live stream. Get them into it, get them involved and show everybody, hey this is the person who won and this is the kind of stuff that you know they're going to be doing with it. Congratulations. But that's where everything kind of went off to the side from what I totally thought was going to happen. I did the drawing and the winner of the drawing actually whose name is Jason Begown. A big thank you and congratulations to him for winning. So what I was going to do, I was going to get a hold of him and say hey you won, let's get you involved in here on the channel, get you on the live stream. He said I ended up calling him, he ended up saying well Kyle I appreciate everything you do and I'm feeling absolutely awesome that I won this and I said you know what you deserve it. Having subscribers like you and everyone else here on the channel is what I do this for. It's for you so here you go whatever you need with it. And he said actually I have more than enough scan tools for what I need. I actually would like to give back to what you're doing in the Rust Belt Mechanics Scholarship Fund even more. So let's do this. My name is Jason Begown, I'm the lucky winner of the Rust Belt Mechanics Ethos Edge giveaway and I want to give back like he does so let's auction it off and make some cash, give it to the scholarship fund, help out the up and coming tax. So we came up with this idea and I was absolutely blown away by his ability to want to do something like this also. Just a random subscriber who won the giveaway wants to give back just like this. What we're going to do instead of sending it to him, he said he wants to auction it off. So that's what we're going to do. We're going to auction off the Ethos Edge Scan Tool here next weekend. I'll get the dates here just a second. But anyways we're going to auction it off and then every single dime of those proceeds are going to go to the Rust Belt Mechanics Scholarship Fund for the new technicians coming into the industry at Sinclair Community College. Just wow. Jason, huge thank you to you buddy. I couldn't say more enough about what kind of a person you are, what kind of a technician and man you are for being able to, you know, take a winning like this, give it back to somebody who really would need it. So thank you very much for that one. So now to the details. If you guys want to get in on this auction, I am going to do it on a live stream next Sunday on the 8th of September. We're going to be live auctioning off this Snap on Ethos Edge. The winner of that auction, obviously we'll get that, the charger and a case for it and get that one sent right off to you and every single dime of that is going to go to the Rust Belt Mechanics Scholarship Fund. Next Sunday, September the 8th, we're going to be holding it live on my channel on YouTube. Everybody can get in on there and we're going to have a couple extra guys in there to be able to watch for all the comments and bids and everything on the channel. Going to have it live stream right then and we're going to have it at 5 p.m. Eastern Standard Time. So for whatever time frame that you guys are across the entire U.S., make sure you guys pay attention for that. 5 p.m. Eastern Standard Time next Sunday, September the 8th. Make sure you stay tuned for that one. Set your calendar. Once again, huge thank you to Jason Pgown who decided to give this thing up and give back to the younger community coming into the automotive field. Big thank you to you. Everybody give him a round of applause. I can't say thank you enough. Big thank you also to all of my subscribers who have been getting me to where I am today. I never thought I would have gotten to this point, but here we are doing some amazing things for some new techs getting in to the automotive industry. I couldn't be more happy about where the channel is going and doing things like this is just something I absolutely love and enjoy and hopefully you guys do too. So make sure you guys tune back into the channel, especially for the new and upcoming stuff coming up through this next week and the auction this coming Sunday. Make sure you stay tuned in for that one. 5 p.m. Sunday, September the 8th. Thanks for tuning in today guys. I appreciate it and as always, you guys stay awesome.


And welcome in everybody, I'm Jeff Levering along with my partner Lane Grendel and up until about five minutes ago we were much like you, we had no idea what we just watched. Did the sausages kidnap Bernie? Do the sausages have cell phones? Do they only send gifts of themselves? Does Bernie always eat that much food for breakfast? And is Bernie safe wherever he is? Well good news on that front. Our sources tell us Bernie is safe and sound. Let's check in on him now. With more good news for Bernie it appears they've moved him from the ballpark for a very special reason. And for more on that let's go down to Nicole Seteve. Thanks Jeff, as the Brewers in Game Host I've developed a bit of a shorthand with the Brewers mascots. I learned Bernie was feeling a bit down last season without fans at the ballpark. So to help cheer him up the mascots have partnered with American Family Insurance to renovate Bernie's chalet. In fact I hear they're about to go over some of the designs of the new chalet in just a few moments. Wow thanks Nicole. What a great gesture by the sausages, you know, except for the whole kidnapping and everything. Yeah, don't they usually send them on nice vacations for these types of shows? Anyway, let's send it live into that design meeting. Alright guys, we've been tasked with picking the best design for Bernie's chalet. Everybody ready to see what the racing sausages have put together? Remind me why we like the sausages do the designs. The last time I was in a meeting with the sausages. They pitched me on being our entire starting rotation. The whole thing, one through five. Listen guys, I'm sure they've got some great stuff. Let's see who's up first. Wow, that is quite the design.  Okay, maybe let's look at the next one. I think maybe he was just...hungry? You know I've always said this, never design a chalet when you're hungry. Yeah, I don't really know about this one. Is he suggesting we recreate the Leaning Tower of Pisa? Or that we can bring the real one to the ballpark. I'm not sure you can move an 800 year old building. Who knew these guys had such solid graphic design skills though? David, how do you feel about a slide that leads directly into the outfield?  It's also missing a front door, which could be a problem. Okay, let's move on to our last one. Is Charizo an architect in his spare time? I don't know, but that looks like a pretty legitimate blueprint. It's very scientific. He's really specific about the angle of his sombrero. Well, that's all five. And I don't think we found a winner. Yeah, maybe time for them to head back to the drawing board. And hopefully not with Graham.


Delhi winters are back along with the signature Delhi winter pollution and Everyone is pointing fingers at farmers and stubble burning Haryana and Punjab are the two main states where stubble burning occurs But the number of stubble burning incidents in October this year was much lower compared to the same time last year But stubble burning did not stop. It was only delayed due to the late monsoons this year A lot of the burning is happening now Despite the delay the air quality was still extremely poor in October So the question is how much is stubble burning responsible for Delhi's pollution woes and is it right to blame the farmers? There are a number of causes behind Delhi's winter air Let's take a look at the two major ones first The cold weather leads to something called Temperature inversion which results in a higher concentration of pollutants closer to the ground Second Delhi air is already extremely polluted around the year These pollutants come from a variety of sources which remain unaddressed Let's first take a look at temperature inversion Hot air rises cool air sinks. That's simple science In winters the simple science causes certain complications In the summer the air close to the ground remains warm So the air rises up along with the pollutants and disperses because of this pollutants don't get concentrated near the ground But in the winter there is less sun The earth surface loses heat rapidly Causing the air just above the ground to become cooler and the air in the upper layers remains warm This is inversion The layer of cool air is then unable to rise upwards and disperse This results in a higher density of pollutants remaining stuck in the lower layers of the atmosphere and Choking the air quality So the level of pollutants in the air is extremely high all year round But in winters the pollution becomes much worse because of inversion That is not to say that stubble burning does not play any role at all But the amount of pollutants it contributes is smaller compared to other factors Also stubble burning happens for only a few days every year Unfortunately, this coincides with the winter temperature inversion conditions So the industries and others who are primarily responsible for this situation Conveniently escape while the blame is focused on the farmers instead Pollutants from stubble burning can be as low as 12% of the total pollutants in the air In certain localized areas closer to stubble burning sites, this concentration can go up to 60% Industries, private vehicles, real estate giants performing constructions, all of them contribute much more to the pollution problem But the state has only outlawed stubble burning with limited action against other responsible parties So the ones penalized are the powerless farmers who are already burdened with huge deaths and a host of other problems We also need to see why stubble burning is happening Farmers have repeatedly said that they have no other option but to burn the stubble Escalating fields in any other way costs too much money In response to this state and central governments have announced joint subsidies to ease the financial burden But the practice continues. The stubbles which are being burned belong to paddy crops Traditionally paddy was not grown at such massive scales in Punjab and Haryana It was only after the green revolution that paddy became one of the major crops in this region and one of the main export crops When harvested manually the paddy stubble left behind is only a few inches high This can easily be plowed back into the soil while sowing of the next crop But mechanized harvesting techniques soon replaced manual harvesting The combined harvesters used now leave behind stubble which is much higher in length This is not easy to clear. It cannot be plowed back into the soil Hiring manual labor to remove this stubble is too expensive for farmers already burdened with debt Mechanical equipment for removing paddy stubble is also very costly Farmers are unwilling to spend so much money on equipment They only require for a few days each year While the government has announced some subsidies these are not enough to make the equipment affordable And these subsidies are only reaching a limited number of farmers It has also been reported that the cost of equipment has gone up Since these subsidies were announced The government and students in different universities have come up with a number of alternative uses for the paddy stubble It can be given to paper manufacturers for making paper Or power generators for converting into biomass-based energy These solutions sound great on paper and can also bring additional income to the farmer But so far there's not been much success in implementing them Even if the rest of the supply chain is established And the stubble is successfully collected from farms and delivered to industries which can use them The first step of removing the stubble is yet to be solved So while it's easy to blame farmers for the pollution and impose fines on them It does not solve the problem of stubble burning And even if the problem of stubble burning is somehow completely tackled The other pollutants in Delhi's air will not let its citizens breathe easy anytime soon


Armenia is another victim of the France. Armenia is another victim of the France, according to experts. At present, Armenia looks to be unwilling to pursue peace, which is supported by a variety of grounds. Accepting Azerbaijan's proposal would be a practical demonstration of a real desire for peace. Similarly, if Armenia sought to encourage improved Turkish-Armenian relations, it would be reflected in constitutional reforms and abandon the mindset of viewing Turkey's territory as ancient Armenian land thereof. Experts underscored the significance of the events in Ukraine as a crucial lesson for the Armenian authorities. Armenia believes that the France will back it. However, France should understand that Armenia will constantly hunt for a new sponsor and patron. Armenia is an open field for France as well as another victim of influence of Paris. In this case, according to Selin Senosak, head of UNESCO's Department of Cultural Diplomacy and Governance, France, unable to digest Azerbaijan's victory, are trying to pave the way for a new war in the region. He said, for the passivity and indifference of the European OSCE member states to Armenia's occupation policy. Because Azerbaijan's liberation of its lands from occupation was not in their interests, Senosak noted.


Okay, so I think we can start. First of all, thank you everyone for staying for today's talk. Today I'm here to talk about ASPUS in finance, but before starting, I'm here to say that I'm not an expert in finance services, I'm here to talk about what I've learned and give some remarks of the experience that some people in the Tudor community that are OSPO leaders around different sectors, including OSPUS in finance, have been sharing across within these years. So first of all, I will give you some context of what's building an OSPO in finance and some of the challenges some of these OSPUS are having facing so far. Then I will be talking about OSPUS and what really is an OSPO and the main character is an OSPO. Then I would like to serve some financial organizations that already have an OSPO and are engaging in Tudor and in other organizations such as Finals. And finally, the main goal of this is also to bring an open discussions on how can we collaborate both Finals and Tudor Group to help more OSPUS in this sector to be created and also have the existing ones to advance. So I will start with some open source context. Many of you already will know that open source has one. And this is from the last open SSF conference in open source summit where they serve this data of like 90% of modern applications using source code and it's very likely that in your organization even though you're not contributing to open source at some point you are using or your engineers are using open source. So if you're using open source it's also people are starting to realize that it's time to give back and not only using because if you ignore that part vulnerabilities and risks can come of just using and not taking care of the open source. So from the Finals perspective there's been some restrictions and sometimes some barriers from people to actually get into open source and get into an OSPOT that I will later explain better and has also be directly affected to the ability to execute to advance in the open source journey. More of those are regulators, organizational culture of the Finals and Services and technology trends. And broadly speaking the three main goals that I've been hearing across all these financial systems with an OSPOT has been we need to awareness, we need to realize the benefits of open source code and collaboration. We need to enable open source contributions rather than consumption and we need to enable safe and compliant open source collaboration and I've highlighted safe and compliant because that is one of the main focus of the financials OSPOTs legal driven states and then from that once they have that move into more community driven states. So for that for starting the open source journey I wanted also to highlight the work that Finals are doing in the open source readiness project. I think they have great resources on how to invite organizations to start taking care of the open source projects and the open source efforts they're doing. So they have an open source policies focused on the financial systems. They have an open source maturity model. They have a working group to discuss about the status of open source and financial systems. I think those are really great resources to get it started and to actually understand the value of open source for an organization in the financial sector. But sadly, that is not enough. Realizing about that open source matters and starting to interact with open source it's pretty normal nowadays. And if your organization wants to start the journey to become an open source first organizations you can take the long way, the long path starting to do open source ad hoc, that is. Okay, there is a vulnerability here. How can we fix it? Let's start with this team. Okay, let's start to do open source as the issue starts and as the issue happens or you can put a strategy. You can have a dedicated team or a matrix of experts that acts as a central place of this so they can guide better and you can accelerate this journey. Because as I said adopting a strategic posture around open source is no longer optional right now. And that is what an OSPO is actually. Some organizations started to put a strategy on top of all the open source efforts to accelerate this open source adoption and accelerate this innovation. So the short answer is OSPO's are more like a designated place that is where you put all the open source operations and efforts and to visualize better this idea I also like to share this graph where it's like okay where's an OSPO, when is the time to start an OSPO? Well if your organization is starting to think about let's have open source policies. Let's have an open source strategy. Let's build a matrix of experts. Then is when you should be thinking about an OSPO. If your organization on the other hand is doing open source at hoc, there are no coordinated efforts, there is lack of alignment within the organization or even the top level management doesn't really understand the value of open source like yeah they know open source is there but they don't really get it. Stay just wait and keep building this awareness. And once the organization realize that they really need strategy and policies and they start to take care of the strategy it's when an OSPO might be a good opportunity to have. So also to explain better and to define better what is an OSPO. Here are some characteristics that can define an OSPO and can help you understand better. So if your organization has an OSPO it's very likely that your employees are tasked with fostering and nurturing open source usage. You have already employees that are contributing code to open source. There are processes, procedures and tools to facilitate this open source consumption. And as I said the decision makers already recognize that open source software it's important for the innovation of the organization's product or services. Here are some of the characteristics that an OSPO can have. And I highlight an OSPO can have because there are OSPs that only focus on two, three responsibilities. There will be OSPs that only focus it more on the legal side or for instance oversee open source compliance or working on the inner source side. But there will be others that tries to gather all the different responsibilities. So this is just an example. So in a nutshell, starting an open source program office means moving from open source ad hoc to adopting a strategic poster on open source, infusing the whole organization with a clear understanding of open source. So what is this? Communication. Because that is sometimes a really important topic that maybe your organization, you have a team involving open source but it's not aligned with the organization's goals and then it's for nothing because you keep building your goals and the organization have another different goals and you're stuck. So it's a way to also build this matrix of experts around different teams that can communicate that can speak the language of those teams and thus everyone is aligned. Everyone knows the benefits of open source and how to be involved in open source. And finally, it's also a way to celebrate open source adoption and thus innovation. But let's go beyond that. I will also talk about a way where people can better frame OSPOS because OSPOS has a journey. Like there are OSPOS that are just starting and they're really seasonate OSPOS that has been there for almost a decade and they have been advancing. So in Tudu, we work together into a maturity model that works as a framework to understand the different maturity stages that an OSPOS can go through and I really want to serve briefly all these different stages and maybe if your organization has an OSPOS right now or you're thinking about having an OSPOS you can try to map where it is in this model. So this model is composed by four different stages. The first one is the legal driven. You need to take care of the inventory. You need to first assess that. Then community driven, engagement driven and leadership driven. And all this depends on the ability, the OSPOS level will depend on the ability to execute. During the first stage, the legal driven stage, as I said, the organizations are trying to identify all the legal and security risks. So it's about careful licensing, developer education, inventory taken. Once the organization has all that in place and they know which project, they have a list of projects like these projects are green light, these projects are red light, okay, let's go. It's when they can start building this community driven stage and start building ambassadors to build this open source education within the organization and train developers to contribute to open source. And also amplify the message. And once that education is somehow adopted, we can move to a more mature community driven state where the employees can actually take actions, take, have quality contributions to open source. And they can begin to streamline and optimize open source of bound contributions for the developers and even launch open source projects. When you are more mature, when the organization is more mature in the OSPOS, they can move to engagement driven states. So they are actually taking action. So it's when they can support incubating and launching open source projects. And it's the time when the OSPOS developing playbooks, processes checklist to help them help the organization start being open source first citizens. And finally, the leadership driven states. Here is when the OSPOS can become this advisor for the city hall and they have the knowledge and the means to benchmark what constitute a good and acceptable open source projects based on where do they want you to go and the technology stacks. And you might be thinking, okay, this is great, but maybe it's too advanced for financial systems and financial services. So that's why I also wanted to show some examples of real organizations in these sectors that actually has an OSPOS. And not only they just started, but they have been there for decades, some of them. So the first two examples, Bloomberg and Capital One, for instance, they've been like, Bloomberg was one of the first organizations that joined to do some years ago. And now they are, they can call themselves open source first company. They have been doing great efforts to the open source community. They know how to get involved in open source. And then Capital One, they started the open source program office more than five years ago. I also want to give a shout out to Goldman Sachs. I think they have been engaging in open source a long time, but they started the OSPO last year. And since last year, the journey they have been taking has been tremendous. They have been engaging in too, as well. So I've been able to follow the work really closely. And they also even created a webpage for the OSPO where they said like, these are all the open source projects we are contributing. These are the open source projects we are releasing our mission, our vision. I think in the open source summit, they talk about the journey of Goldman Sachs in the OSPO. Really recommend you to take a look if you haven't done so. And also wanted to highlight all the OSPs that are being formed, Fannie Mae, for instance, and more that are yet to come. That they haven't served that publicity, but eventually they will do. So there are, this is a movement that is happening, also in the financial systems. And this is not just organizations in the early states, OSPO, but also organizations that are quite seasonate. So to end up with, I would like to open up discussions here because I think the main goal of this talk is to discuss about these topics on ways how can we work together across communities to increase OSPO adoption within financial services. So here are my three questions. The first one, how can more OSPOers help out financial services firms? I mean, how can other OSPs from other sectors serve their knowledge and can those knowledge be an inspiration for OSPs that are being formed in the financial services? Also, how can OSPs in financial services, the existing ones, collaborate with other OSPs to build and contribute to common tooling and infrastructure? And finally, how can we infuse OSPO learnings into a Finnish readiness program that is focused on help financial services to adopt open source and build this strategy and politics across open source and help its adoption in finance and banking sector? Just two more slides and then we can go through this open discussion. Start the story about Tudu, because I've been talking about Tudu, but I haven't explained what it's to do. It's also a Linux Foundation project. It's an OSPO network in a space, but we also create resources. And the good thing of this is that it's the community builds it. So it's formed by OSPO participants and OSPO leaders worldwide and across different sectors and divisions. In fact, Goldman Sachs is there, Capital One is there, Bloomberg is there. So there are also OSPs in finance working on these resources. And we do these OSPO guidance and support through networks, spaces, education, training, research and tooling. And this is me. You can follow me on Twitter or connect with me on LinkedIn. Happy to do so. And thank you so much. And we can move now to questions and then to the open discussion. Thank you. Okay, so are there any questions or we can maybe try to bring this discussion on how can we, Tudu can collaborate to have this OSPO adoption in the financial system. Yeah, yes, Tudu. So right now we have the, how's it called? Whipple Inter, that I'm not in the project itself, but as far as I know, it's a way to scan, look for issues on every single repository. I don't have a lot of videos on that because as I said, I don't contribute to that, but if you go to Tudu Group GitHub Organization, you will see all the, you can read the redmi file and see the tooling for, that is focused, I know like a lot of OSPOS uses it. And I think Chris is there and he contributes to that. So maybe he can say more details about the project. To start an OSPO. So first I will say, Andrew, I'm gonna go here because I think this is key. First, ask, try to see where is your organization in the open source journey? So are you working on a strategy on policies? Is the top level management aware of this or not? If they are willing to start these policies and strategy around open source, then start thinking about building these metrics of experts. Like where are the right people across teams that can start collaborating in this open source and act as the center of the open source operations? And well, and of course, many OSPOS, what they have started with was doing the legal driven states. So starting with everything related with taking software inventory, building the list and covering all the risk and licensing things and, yes? Sorry, I'm trying, okay. Any other questions? Yeah? Looking to open source projects is a problem. It's demonstrating value to management in consuming from open source projects which is a lot harder to do than making contributions to open source. And in order to consume open source you have to have the policy and everything where it is in place because you're taking code now from the outside and you bring that into your organization. So I guess the question for me is how do you convince management to put through the effort, to go through all the effort of putting the policies together so that you can actually consume to demonstrate the value? So I guess that was the question of high. If you have any thoughts, anyone has any thoughts on that? I mean, I think there are many ways to do that and I can give some suggestions but these are not like rules at all. I think if engaging with communities like, for instance, to do one of the feedback that I usually heard is that I can talk with all the people that have same issues as me and for instance, convince us the top level management of building policies around it's one of them and I can get some inspiration of what others did in the past and apply them. So if you have time to go to this network in spaces, I think it really helps. There are also some articles from people that had an Ospo starting an Ospo and actually it's like how to convince your manager to start an Ospo. One of them is in the Tutu blog but one of the Tutu members is Ivan. So I really recommend to at least take a look. Maybe you can find something interesting there. Yep, good point. Yep. I think it's the financial component of the city. We've all found a great place for anyone who's a large factor to go to see where they're in value. So for those of you who don't know that, that's to do with how we've been up to our construction, which is to find which of the common problems are solved. So there are plenty of opportunities to demonstrate the value of the system and be sure to be at the risk of making it better than how it might be shared away. Just to add something on that, I think like doing from bottom to top to top down, I mean, both approaches needs to be done in this, like not only top to bottom, but also the other way as well. So if there are no any other questions, thank you so much. And if you want to chat or catch up, I'll be happy to do so in the break room, in the hallway. Thank you so much. Thank you. Thank you.


What is up everybody, it's Stas here and in this video we're going to be doing an overall market update taking a look at the Dow Jones, the S&P 500 and the NASDAQ. We're also going to be doing a trading update talking about what I did today in the markets as well as some stocks and ETFs that I have my eyes on right now and I'm looking to trade in the month of December of 2019. And as you guys read in the title, we're going to be talking about you guys in this video yet again, natural gas and D gas and kind of what sent down the overall markets today in terms of the S&P, the Dow and the NASDAQ because if you saw and if you look at my screen right here, you can see the markets tank today. And I want to go over that and kind of break down some technicals. But before we do all I ask from you is if you enjoy the video, simply go down below and hit that like button and consider subscribing. If you want to see further content from me and if you want to be further connected with me and the StriveSmart community, the Discord group chat link is down below as well as the Facebook group link down below in the description box. So let's talk about the S&P here guys just like we start out in every single video. The market just closed 7 minutes ago and the S&P closed down $27.11 down .86% which again is one of the biggest red days that we've seen here in the recent history of the market. If you guys can see over the past couple of weeks dating back to probably the beginning of October, we haven't really seen a sell off this drastic. Maybe this day right here probably was the last day that we saw this big of a sell off but ever since then it's been two months almost of straight running up for the S&P. So this was a much needed correction in my opinion and if we zoom in a bit on the S&P to kind of break it down, it makes sense right? We pushed up to $31.54, hit that all time high. We got extremely overextended in terms of the RSI and honestly we were overextended above that 50 S&P a lot in my opinion like I've been mentioning in these videos. So it makes sense that we're pulling down right now and technically we're still at a higher low right here on the S&P from the previous and although we broke that 50 S&P support which is not too good, we're still holding that 180 S&P support which is this yellow line. So that's a pretty good sign and the RSI is all the way to the oversold side so this could be a potential dip for the S&P. All we need to see is this pop now and ultimately a break above the EMA and honestly that 50 S&P as well and that's kind of what I want to see before I buy up this dip on the S&P 500 right? And if we zoom in a bit more you can see you know bulls kind of took over here if we actually go to the one day one minute you'll be able to see it a bit better. You know we sold off aggressively like we saw lost about 40 points on the S&P then the bulls started to take over here. Then ultimately the bears kind of took over again in power hour sending us down to pretty much the support level at around 31.10 that we got to earlier on in the day. So in terms of the S&P here guys is this a bottom? We have to wait and see for the futures tomorrow morning in my opinion right? If we're gapping up 5-10 points in terms of these futures you know that's a good sign that this is the bottom and we're continuing up and if we go back to that hourly chart if that happens in terms of the futures gap up we'll be pushing up very nicely. But let's say you know these futures gap down we break this kind of triple bottom support we're seeing to the downside that's going to be quite negative in my opinion and who knows we may see further selling off from there. So that's kind of my thoughts here on the S&P and kind of what happened in today's action and you may be asking yourself what is causing this? Well it's really the tension between the U.S. and China right? If you guys recall a couple of days ago Donald Trump the U.S. President signed a bill in Hong Kong and now China is kind of retaliating with sanctions against U.S. human rights and a ban on military visits and this is actually not what we want to see right now. Because if you guys remember on the 15th of December that kind of rhyme that was not planned but on the 15th of December guys we have 150 something billion dollars of tariffs that are going to be active again. And this is something that in my opinion if they go into effect and really the trade war worsens this market is going to hit. I think the market is going to take a hit but I personally think if these tariffs A get pushed back which we've seen in the past or B completely get wiped out if that happens I think that's going to be fantastic for the market. But with this uncertainty right now China and the U.S. kind of going back and forth with Trump going kind of behind President Xi's back you know in terms of that Hong Kong legislation. These things happening right before that December 15th deadline that is causing some uncertainty in my opinion which is why we're seeing this sell off. I'd love to see what you guys have to think about that down below the Dow Jones here guys got hit almost 1% 270 points in the red today we pulled down aggressively from that all time high you guys can see it. We tried holding that 50 SMA on the four hour chart ultimately we're breaking below it that's not too good of a sign there. You know on the hourly chart you guys can see we failed breaking out of the EMA which would have been fantastic for the bulls but we got rejected right now we're looking to test the 180 SMA on this hourly chart. This breaks guys that's going to be extremely bearish in my opinion for the Dow Jones and kind of like the S&P you know we sold off the bull started to take over here started to see your rally but ultimately we sold off and we actually hit a lower low so this thing really downtrended for the entire day right and if we pull up the NASDAQ let's pull up that four hour chart first before we dissect the smaller time frames you guys can see healthy pull down right higher low we're holding that higher low from the previous although we did break that 50 SMA on the four hour chart we're still holding above that 180 SMA which is a pretty good sign and if we zoom into the hourly chart you guys can see although there is a bunch of crap on my screen right now which I do apologize about we're still holding that higher low like I mentioned which is looking quite good but now I just want to see that break above the EMA which is this light blue line here on the chart and I think that would be a good signal to really buy the dip on the breakout on the NASDAQ right here so overall guys that's what I'm looking at in terms of these markets and kind of what sent the markets down today a lot of uncertainty that's what it is we know the markets hate uncertainty and that's really what's sending the markets down at this point so let me know what are your thoughts on that and I'd love to hear your thoughts because we are a community at the end of the day so let me know down below and let's talk about what I did today in terms of my trading so in terms of my trading today guys I took a position in Tesla ticker symbol TSLA and we saw an extremely bullish move this morning on Tesla which is really what prompted me to take this initial position I did not catch it here on this massive spike that would have been nice right if I got in at about 330 but no I did not catch it there I actually caught it on the pullback here at about 332 bucks right I think I got in initially at around 332 and this is a position that I'm looking to swing trade and if you guys saw my video yesterday I talked about kind of more in depth why I wanted to get into Tesla but I'll break it here breaking down here for you all in a two minute little clip so we all saw what happened in the past week while most of us did you know you saw Tesla go from 360 down to about 330 bucks and the drop in Tesla came after their unveiling of the cyber truck right the stock I believe dropped the next day about 6% dropped a couple of days after that until we found a support about two three days ago at around 330 bucks so we held it this day and we held it the next day which then kind of prompted me to look at Tesla for a potential entry we held it again I believe this was on Friday then this morning we launched out of that 50 SMA resistance which is what I talked about in yesterday's video as being kind of the confirmation point for me to enter once we break that level if we break that level that's where I'm looking to enter so we got that break again this morning like I said on the one day one minute we saw it that very bullish move and that prompted me to get in on the next pull down again at around 330 233 is where I'm currently in right now and I plan on adding more money into Tesla probably if we break around 340 bucks that's where I'm looking to add my second position and ultimately I'm looking to swing trade this one to at least 350 that's my first sell point and probably just get out of it completely at around 360 bucks so in terms of my trading guys no day trading really today you know it might have been a good day to trade TV IX but honestly I didn't although it was up 10% and by the way yes they just saw a reverse split which is why it went from 6 bucks up to 70 bucks and you can see up 6 bucks today again like I said 10% it would have been good to trade it but I didn't trade it if I'm being completely honest with you guys you know SQQQ could have been good today SPXS these are all that go up whenever the overall markets are selling off so overall that is what I did I added a little position into Tesla I'm still holding my Home Depot shares and I'm kind of waiting to see if this market ends up rallying back up from here I want to see is this simply a correction before we continue to higher highs or is there further downside in store here because again with trade with these tensions with uncertainty a lot of stuff could happen so I'm being honestly a bit more cautious here over these next 10-14 days than I normally would be but I'm still being aggressive right at the same time I'm being cautious with storing cash waiting for deals but I'm still investing I'm still trading in the market you know because I believe in it at the end of the day so let's talk about you guys D gas natural gas then we'll talk about a couple of stocks and ETFs that I'm watching right now in December so you guys today guys up 8 cents up 1% almost 0.86% to be exact and today honestly felt like kind of a calm day for natural gas D gas and you guys really it's been up and down crazy volatility over the past couple of days but today was kind of the calming before the storm it feels like right this thing I feel could go up a ton tomorrow or it could end up dumping through the floor yet again because these technicals they're not really showing us a definitive breakout or a definitive dumping point because you can see sure $8.50 and more like $9 I guess you can say is a short term bottom based on these technicals right we kind of bottomed out there on the 29th of November we bottomed out there today twice and we started to break up a bit into the close of the market today so that's a good sign for temporary bottom but we're still not full on exploding out quite yet which is why I'm not really convinced quite yet that this is a full on breakout but on the flip side again I'm not convinced that we're dumping quite yet because we didn't definitively break down below $8.90 to about $9 quite yet which is that very strong level of support so very calming day today for you guys D gas natural gas in general if you go to D gas you can see you know this one was up or rather down 4% today but still that's nothing compared to what it's been doing these past couple of days guys you can see a couple days ago it was at $108 then it went up to $180 in the matter of 3-4 trading days which is ridiculous so a 4% move either up or down at the end of the day that's really not much at all for D gas you know considering what it's been doing and if we look here at the natural gas futures guys the January contracts they're up about 6 cents up 2.63% which is kind of odd because you guys is really not moving you know like the way it should be because it's supposed to be a 3x ETN but it's up almost 1% but the natural gas futures contracts they're up about 2.6 to 3% so that's a bit wonky today I'm not exactly sure why that is but sometimes I've noticed that you guys and D gas they don't move exactly 3% in terms of that correlation with the underlying asset which in this case is natural gas but hey sometimes it does sometimes it doesn't and that's really the risk that the risk that you do take when you trade these but anyway it was up 2.63% today you guys can see this is where we kind of bottomed in the middle of the day at about 11.30am eastern standard and we started to climb from there which is why you saw you guys sell off this morning and then slowly start to rally back up so I guess you can say from the bottom here 8.90 up to about 9.30 that was about a 5% move so let's see what that was on natural gas to see how that correlates so 5% for you guys the bottom move from 2.30 up to about 2.40 yeah see that's about 1.8 so yeah 1.8 times 3 that's roughly about 5% so you guys can see how that correlation is between these futures and you guys let's talk about some weather here that I'm looking at over the next couple of days that could definitely impact the demand in these next couple reports that we're going to be getting for natural gas and maybe even hurt the demand two strong storms will impact the US early this week with one currently tracking through the Great Lakes and the east with areas of rain and snow and highs of 30s to 50s a milder wetter storm will bring heavy rains to California with nearby states the rest of the country will be mostly mild and dry to open the week besides the colder north plains a reinforcing cool shot will sweep across the northeast midweek with highs of 30s and 40s but the rest of the country will be relatively mild with highs of 40s to 70s the warmest area being the far southern US overall based on NatGasWeather.com the demand will be moderate to high this week the week being December 1st to December 7th so as we all know and I've been mentioning this in these videos over the past couple of days in the short term natural gas demand has been weak we've got a 28 billion cubic feet withdrawal this past week which was far far lower than what the estimates were which is why we saw that ridiculous dump in natural gas and a lot of people have been saying natural gas has been trading as though winter is over so that is interesting point because we kind of saw a peak and we're seeing a heavy decline here like the real cold weather has already left and that's an interesting point of view that I'd love to know what you guys have to think of and really that is kind of what my thoughts are in terms of natural gas right now in the short term sure we may see a bit more downside due to this mild weather due to the warmer weather that we've been experiencing and like I've been mentioning over these past couple of days but ultimately I think a bullish inventory report could be a catalyst here that shoots up the natural gas prices because we saw a bearish report send them down so heavily I feel like any bullish any sign of bullishness right now could send this thing flying right back up maybe to 240 maybe mid 240s again which could give us an opportunity for you guys and at this point guys seriously I think the low point for natural gas is nearing I know a bunch of bears out there they're saying $1.80 but honestly I don't really see that happening maybe 220 at the lowest that could potentially happen but honestly I see this thing rallying back up in the next within the next month I'm not going to put a time stamp on it well I kind of just did but within the next month I'm looking to see some sort of bullish momentum and I really do think you guys will recover within the next couple of weeks and we just have to be patient continue watching these weather reports continue dissecting these natural gas reports the inventory reports and that's what's really going to give us the hardcore data behind whether that move in natural gas to the upside and thus you guys will ever come right so those are my thoughts on the subject let me know down below what are your thoughts and let's talk about a couple of stocks that I'm looking at right now rapid fire in the month of December so the beauty about stock markets sell-offs guys is it opens up opportunity for those that are looking to buy the dip and with the big dip we saw in the markets today a lot of stocks that I've been watching opened up one of them being in video guys ticker symbol NVDA and I actually talked about this one in yesterday's video on Sunday's video and I was talking about how on the three-year chart we're seeing a potential gap up from 210 or rather 220 up to 250 forming right now for NVIDIA right we saw how bullish it's been you know ever since it's dumped from about 290 to about 130 and it's really just been completely bupple of weeks guys if you look at the 90 day chart this thing has been ridiculous from 140 back in August to about 220 here just three and a half months later and now with this pull down that's opening up a nice 5% potential on a stock that again looks like it could break out from 220 to 250 so this is a really good dip buy in my opinion at about 210 and honestly heading into tomorrow I'm looking to see if it holds and maintains and kind of rallies around this 180 SMA support on the two hour chart being that 90 day chart and honestly on the hourly chart on the 20 day chart I'd love to see a rally back up probably to 215 maybe not 215 maybe 213 before considering a position so NVIDIA I'm liking it I just need to see a confirmation of a bottom or some sort of support forming and then I'll probably pull the trigger on NVIDIA Chipotle Mexican Grill CMG is the next one that I'm looking at this one actually hit a high yesterday or rather on Friday at about 825 we sold off to 800 and we held that 50 SMA on the hourly chart which has been a support level over these past couple of weeks that's quite attractive that the uptrend is continuing and that this thing wants to push up and maybe even test 835 which is that next major resistance that I'm seeing here on the stock right and if we go to that four hour chart this is looking very bullish we broke the 180 SMA if you guys remember actually swing traded Chipotle from 750 up to around this area at around 815 sold out now I'm looking to reenter on this bullishness so very very bullish EMA popping above that 180 SMA we're pulling down we held a higher low now all I'm looking to see is what the futures are looking like tomorrow morning are we continuing this push to the upside if we are I might enter in 815 820 and ride it up again to about 835 that's kind of what I'm looking at here with Chipotle Mexican Grill NEO stock NIO did very very well today up 8% yet again and now it's testing that same resistance 240 250 roughly that it tested a couple of days ago and failed guys and I think if NIO breaks this level if we look at this four hour chart there's a lot of potential guys up to about 270 and stocks like NIO penny stocks they can fly like crazy in the matter of a couple of days they can go 20 30 40% up right it's it's like no problem so NIO I'm looking to see if it does exactly that from 240 up to 270 that's about an 11 to 12% profit margin that could very well happen and who knows from 270 up to 330 I know that's a bit a bit um what's the word that's a bit out there right but hey it could happen these things fly up on any single piece of really good news like that mobile ideal with Intel ever since them this stock has kind of been rallying up right so up to 330 that's a 37% potential guys on NIO so I'm looking at this one although it is speculative a bunch of people probably don't like trading stocks like this I think it's worth it if you are a bit more risky and yeah I wouldn't trade a lot of money with NIO I just trade an amount that I'm willing to lose and that's kind of what I'm looking at for this stock the last one here is ticker symbol NFLX also known as Netflix guys and this is one that I almost took a position in today and I talked about this one in yesterday's video as well and remember the two scenarios from yesterday's video one of them was we might break 320 and then enter there for a swing up to 340 or we may pull down to that 50 SMA and get a better margin of profit that's what actually ended up happening right we got rejected by 320 pull down we're holding 307 309 here and now it seems like we're continuing the uptrend so why didn't I take a position in Netflix guys honestly I don't really know why I just didn't feel comfortable pulling the trigger quite yet and really I'm just going to wait until tomorrow there's no there's no sense of rushing or rather there's no need to rush anything and I'm looking to see if this continues upwards if this gaps up tomorrow as well maybe the 311 312 that's where I may add a little bit then ultimately wait till 320 to see a test there again and if it breaks that's where I'll add a majority of the position with targets of selling at about 330 so

This meta-analysis assesses the effect of ongoing statin treatment on susceptibility to influenza virus infection and mortality among flu-vaccinated and unvaccinated patients. The results show that statins are associated with a reduction in influenza prevalence, or equals 0.85, 95% Ci, 0.73 to 0.99, P equals 0.040, but not with susceptibility to influenza infection in distinct communities of either vaccinated or unvaccinated subjects. Additionally, the use of statins among patients with influenza was associated with a reduced mortality, or equals 0.68, 95% Ci, 0.56, 0.82, P less than 0.001, which was confirmed for both 30-day mortality since influenza infection diagnosis, or equals 0.61, 95% Ci, 0.47, 0.80, P less than 0.001, and for up to 90-day mortality, or equals 0.74, 95% Ci, 0.55, 1.00, P equals 0.042. These findings suggest that statins may have a potential role as adjunctive therapy in patients with influenza infection, but further research is needed to confirm these results and define the optimal dosage and duration of treatment.
