Okay, everyone here, the screen is on. Oh, the screen is not on this. Let me change that. Yep, you can see anything. Yep, good, I'm just fine, so welcome. Welcome to this talk about gate ups in motion and infrastructure as code. So first, I'm Vincent Gillett. I work for Zeneca, been in this business for way too long. And I was very fortunate four years ago. There was a very big French financial institute that came to me and says, hey, Vincent, we're moving to AWS, we're changing everything and we need to revamp our old CI CD process plus our continuous deployment. And you've got a wild card to do what you think's best to do this on the state of the art and that will remain state of the art for the next few years. So instead of having like yet another GitOps talk, well, they're gonna show you that you can deploy something on a Kubernetes cluster by just git committing something in a git repository. Here, we're gonna share with you the failure. Oops, sorry, the mask is a little bit loose. Yeah. So I'm gonna share with you guys three years of real production of doing GitOps, the success, but also the failure. Here we go. So buckle up because this Stokes is like 25 minute or something like that. And we've got a lot to chew on and a lot to talk. And before we start, I have a very strong disclaimer for these Stokes before you're trying to do this at home or at your company. This here and here is the picture of your SISO and its team. This is what they should look like. They should be working hard, sweating on their keyboard, working with you to enable you to do the job that you need to do. If your SISO is more and its team is more of the properly suited with the nice ties that show up in meetings and say no to everything you asked for, you have the wrong type.  You want this one. Because if you don't have this one, don't even bother proceeding with everything I'm gonna talk about. This is a very strong prerequisite to your DevOps journey. This is what you should have. So no, disclaimer's gone. We can go. So here's a few definition. The infrastructure as code definition should be pretty straightforward for you because it's been a long time so we're getting familiar with this. So it's code that is describing a desired state to interact with the API of a cloud provider. That's simple, right? But what's very important in this is the desired state work. We're gonna see that all along the stock, right? But this is very straightforward for you, I see. For GitHub though, this is a complete different story because this is like what for two, three years become the very buzzword. It's all on this bingo card of all conferences where you go to how are we gonna talk about GitHub or not or anyway. And I see a lot of blog articles in there and even like official pages from really big software company that describe the GitHub's way to do things and most likely I'm very disappointed, they're completely missing the point. For instance, the GitLab pages that says everything to do about GitOps is very misleading and completely missing the point. The companies that does this, right? It's a company called Weaveworks. They are the guys who did flux but they also have the guys who did EKF CDL. They did the Weave things for Kubernetes and they are actually the first guy a few years ago on a blog and a white paper put on paper their vision to how we should manage and operate Kubernetes payload in a cluster. And we would call it GitOps and then the release flux. And they have a way to define GitOps with four pillars that are extremely important. You have the first one here which is the entire system is described declaratively and not imperatively. Remember the desired state we had from infrastructure as code? Same thing, right? We don't tell AWS to say how they should spin up their EC2 for us, right? We're just saying we want an EC2 with this configuration, this networks, their business then, you know? It's AWS business to spin it up and hand it up to me the way I want it. I'm just describing what I want. First thing, the second one is pretty straightforward because we have code somewhere should be in Git everywhere, right? 2022 it should be fully common to have the things. The third one is where it comes a little bit tricky. It says that if we have a change somewhere that is approved on our Git repository, it can be applied to the system. I strongly suggest that it should be applied to the system and it should go because it's already been approved yet, right? So every change to the systems goes, every change in the Git repository goes to the systems. I don't want to say the word but that means there's some kind of pipeline somewhere here that listen to the Git repository, do stuff. And my resources either on a VPC or on the EKS get provision and properly configured. And usually people stop there and said, oh, okay, yeah, I'm doing GitOps. I have all of this. I have a huge pipeline on GitHub or GitLab CI's. I have all my code there. All my operation is managed through Git and I have the thing. So yeah, I'm doing GitOps, right? But they forget about the last pillar, which is actually the real game changer. This is what if you're not doing GitOps in 2022 right now you should try to build it ASAP because this is a real game changer. The fourth one they forgot is that there is an agent somewhere, usually inside your Kubernetes cluster that listens to this Git repository and stubbornly every three minutes, if there's a drift reapply the code that's on Git.  All the time. This is a huge change compared to infrastructure as code because what I do infrastructure as code, I spin up my terraform, apply it, got my whole system, it works pretty well for a week. I don't know why, but the week after something breaks, what I do? Well, I SSH into the machine, I try to investigate, then I discover it's DNS because it's always DNS, right? And do the change and then forget about it, go back to sleep, right? This is not possible with GitOps because if I talk to the Kubernetes API to just change an annotation or edit a config map within the next three minutes, all my change is gonna be erased because the sources of truth is the Git.  So this is what it's such a huge game changer into your deploy process in a company for Kubernetes and soon a code. The third kind of definition that will go through all of this talk right there, it's a principle that is very well known in IT, it's called KISS, keep it, it's stupid simple.  We want things to be very simple. We don't wanna build very complex system. We wanna build simple thing that handle complex problem, okay? If I had a dollar every time I heard in my career, let's build a framework, I'd be so rich, trust me. Okay, so altogether here, let's start our journey into GitOps and infrastructure as code and let's build a system but the first thing we need to do is actually think about the criteria we want for our system. We want our, before designing, we want our systems to be secured, we want it to be maintainable and you've got this laundry list of birth word, you want it automated, highly available or you also want progressive deployment because you've been on that meetup a few weeks ago that we're talking about category deployment and it felt so good and you really want it also, you want it elastic, resilient, blah, blah, blah, you want the whole thing, right? But trust me, if you try all of this as one, you will fail, badly. You will not have achieved a single thing, okay? So at first you really need to prioritize a few of this criteria because sure, for instance, being highly available is very interesting and you want it in the hand but do you really need it? D zero, right of the bat? We're gonna build a system incrementally, slowly, surely. So what we really need in there is to select those three things. First we need to design something secured because secured come first, secured come second, it come third, security, there is no compromise about it. Security should be the very first and the very last thing you think about when you're designing a system or you're writing code. So no compromise on security. Even third, it's the starting of our process. We want it secure already and we want it maintainable and easily understandable. Why is that? Because we're starting our journey, right? We're not very familiar with this. It's a complete change way of thinking your deployment into your cluster, your organization, your process, direct from Git to cluster, right? So you want things to be easily maintainable because you're starting a new things, you're gonna change things left and right, you know those bricks of Lego, they'll need to be updated very soon, you're gonna change stuff. So I don't wanna lose time with this, right? And the second thing is easily understandable because obviously at start things will break and I don't wanna spend a couple days on GitHub issue and stock of a flow on the other screen trying to understand what went wrong. And on top of that, you want it to be easily understandable for your team but it also helps, for instance, your management because you can clearly explain what you're trying to achieve instead of showing him a very complex AWS diagram with Lambda everywhere, you don't even know where to start for and he says, yeah, sure, okay, let's do it, right? So this is the first three things you should focus in your system, security, maintainable and easily understandable. And then when you have this, probably you can try with high availability, a little more automations along the way and in the end you will achieve all of the things but not everything all at once, right? So, oops. So right of the bat, I'm gonna show you the architecture of a deployment for infrastructure as code, state of the art 2022, be ready, donna, looks like that. It is kind of deceptively simple, right now for just such a state of the art things. I only have what Lake says, three rectangles at most but there's still a very interesting thing on that diagram. So you see there's a server somewhere that runs through things called Atlantis. It's inside a VPC, right? And it's running on an EC2. We'll see later on if there's any question why on an EC2 and why not and a fancy AKS we could see them out. But so what the things does, it's wired to your Git repository like GitLab, GitHub, whatever. Properly connected to a few repository in there and I work in there and I put my code and when I open a pull request and I push some code, this things will fetch the code and do a Terra from plan and nicely send me the plan inside my pull request as a bot, very nice. Because then I can only work in GitHub or Git Labs and I've got all my things, right? All the points. Until the plan fits my need, right? I keep on pushing, keeps on putting me the plan and when me and my colleague are satisfied with the plan we comment on a PR and said, oh, Atlantis, apply, poof. And then Atlantis in the VPC will actually apply the code. Resources spins up. That's it, you close the merge request, you get to go. But this is just a very fancy, I can be like nice feature because you're working in your pull request but actually the real change in there is very subtle is that you are inside this VPC already. This EC2 is running with an instance role with have a least privilege policy that halloween to spin up these resources no more, no less. Nothing new. It's from within the system that I pull the change and I apply it from the system. Do I need an AWS API key outside of the system? No. Do I need to give like a complex GitLab CI, GitHub Action, SpaceLift, you name it, all of the things that are external to the system? No need. The change come from within. From a security point of view, this is really good because you can have the key to this VPC, you spin up this Atlantis and then you swallow the keys, no need for it. Or you'll probably keep it on a safe lock, right? Don't delay it, right? But you don't need it, your developer don't need it, nobody need it because it is already from within that you push the change. This is extremely strong. On top of that, because on a note trade, because it's running on an EC2 in there with those instance roles for those that are familiar with let's say Terraform, in your provider you don't even have to specify the roles you're gonna use, the account you're gonna use because it's already on the machine. It's already in the Atlantis. So my provider is deceptively simple as well, well it has its version and that's it. Because the Atlantis is already having the role. So when I'm doing the Terraform apply, well he doing the Terraform apply, credentials are already there and they are within the system. I don't have to give them the credential. And for GitOps, it looks exactly the same way. Instead we're not in, well we are also inside of VPC of course, but we are inside an EKS and it's the same concept. I have this flock things that is running inside my Kubernetes cluster that is properly wired to the GitLab repository somewhere. And you configure it for this specific Git repository, specific branch, specific subfolder and every YML file is gonna find in there is gonna stubbornly trying to kubectl, apply, minus F all those files, nothing else. But we are inside the EKS. He's the only one that needs the service account that have the right access to provision, modify resources. You, your GitHub action and your developer, they don't need it. There is no need for right access outside of the cluster, which is from a security perspective is very strong. I'm not trying to push the change from a CI or a CD. It's an agent inside that is pooling the change to the system. And on top of that, that things does it every three minute. Okay. So, here's a bit of the list. I think I've talked to about everything in there, external access, yes, blah, blah, blah. Git audit for free. Oh, don't forget, Git is not immutable, right? Git push for still exist, still a thing. One very important thing in there also I haven't mentioned is that Evan thought we have so two new software but they're very lightweight and we don't have like a bunch of them. They are talking natively, Terraform and Kubernetes. We're not having an extra DSL. We're not having an extra also, say third-party airbag that sits on top of it in between. This is for those who likes so much or go CD, right? You need to configure access to the things with Flux. You don't need to because it's already inside your cluster and your access is managed by your Git access. Who can access Git can access the cluster, right? So, I think we're pretty secured. We're pretty maintainable also. It's just only a few rectangles here and there that can update very easily and they are speaking the same language that I already do, already do a few Terraforms and I do already a few Kubernetes object, right? And easily understandable as well. So I guess we're pretty good to go. But now you're gonna tell me, Vincent, this is very nice. We've seen this design, but what about the Git repositories structure, right? Because as you've seen in the previous diagrams, the Git repository were black boxed. You couldn't see a thing. So if you're gonna say to me, Vincent, but who has access to the Git repository has access to your environment, I'm gonna say yes, but you gotta watch out. Who's gonna access it? And how to architecture your Git repository? Because now you have some sort of a whizzy week what you see is what you get in between your Git repository and directly what you have in your VPC. So 99.99 of the time I see a team starting this journey, their very first idea to do their Git repository looks something like that, right? Looks also very simple, right? I have to admit it looks very simple. So there's this idea, we have like a mono repository here and there and it has specific branch for each environment, the Dave, QA, Prod, blah, blah, blah. Oh, thank you Git flow. I wish he never existed, but it still looks very simple, promising, right? But in reality, it turns like that. And this is base case scenario, right? This is really base case scenario. Because in the end what happens is that you will never ever be able to merge or re-base those branch together. Never. Maybe if you lucky a cherry pick here and there, good luck with that, right? But why is that? It's because each of your branch is having very specific value, specific parameters, maybe even specific resources for this specific environment. So you will never be able to just having this model repo and just promote all of this commits that you have in there. It's not gonna work. And usually when I said those 99% of the team started like that, we started like that, right? And there's always like within less than a week at most a sprint, people realize and said, oh, Houston, we have a problem. It's not gonna work. Very, very, very quickly. So they move on usually with the second pattern, which is something like that. And you can find that in some blogs talking about Github and the way to architecture your thing that says, okay, so we still have this model repo here somewhere. But instead of having those branch per environment, we're gonna have subfolders for there. For instance, we have here the project, but we have also our staging Singapore environments and stuff like that, right? And if we have a few or fewer, then we'll keep on having a different subfolder. So this is how we start, right? But three weeks later, it looks more like that and imagine in a year. And on top of that in here, there is two problem. Well, at least there is one problem and what big inconvenient in there. The thing is that Github, you cannot manage its access within the repository. It's kind of all or nothing, right? And there you have the access to write or merge a pull request into your Github and see everything in it or not. But there's no in between, right? I'm not gonna say, oh, you can see what's in the Singapore environment in there, but in my other subfolder, which is Tokyo production, there's no way you're gonna access that, right? It doesn't work in here. This is the pattern I usually find in clients that has this platform team, this SRE versus DevOps, right? DevOps decentralization, SRE platform team, get holder centralization. And they don't care about the access because they access everything. And if you're not in the team, you don't need to access. So they don't care about this pattern. And this pattern actually, it works if you are in this kind of company that have a very strong silos of the cloud providers. But if you follow the Conwellow and the companies, they often restructured, they change a lot. Projects change ownership. Environment change ownership. Projects getting restructured left and right. So know what happens in a year if I'm a very successful business, I have this and I'm hoping in Europe, but in Europe, they have their own team and I'm gonna cut in health disrepository and send them over and says good luck, right? It doesn't really work like that. So it is very, very, very rigid. And also I mentioned the execution context is that in there, you remember these Atlantis that is properly wired to this. So that means it's properly wired to one sub-folder of the whole repository. You better not miss the target, right? And I've seen that happen, the very usual P-prod, you know, with a typo and then one P disappeared and then suddenly you have pre-production going directly into production.  So this is very prone to mistake this kind of structure with this all in one in there, right? So in the end, I'm gonna say, no, we can do better, right? Not gonna work for us. So why is that? Just a little bit of academic things. So this is the MOF pyramid. For those who did UML, yeah, I know UML, right? Better a few years ago. So at the very bottom here, you have the instances, the real world, and just on top of that, you have the model and the metamodels and everything. And this idea of the mono-repo is not working because your mixing things that don't have the same life cycle. It's not because you wanna change the chart of the instance of a chart him that you need to also inconveniently have it change somewhere else in there, right? You don't wanna mix in them. Things that don't have the same life cycle don't belong to the same git repository. You want loose couple on this. Mono-repo is cool, but what really works, and trust me, I've been doing this for a long time, what's even better is trunk-based. And I'm very willingly able to sacrifice mono-repo for trunk-based, much more efficient. If you can have both, by all means, do it, but I'm not so sure it's gonna be very convenient to have a mono-repo trunk-based, think about it, it's gonna be a mess. Oh, trunk-based, it's much more efficient than those mono-repo. So here's what you should have here, the complete diagram for your things. So the part on the right, nothing's changed, the same Atlantis, the same resources, the spin-up, but here on your git repository, you have very thin git repository that are responsible for a very tiny layer. My KMS to uncrypt that rest, a few things, one layer, EKS control plane, one layer, a few of my nut groups, another layer. You multiply all the things, very easy. So you can do trunk-based very easily, and then suddenly what you're changing is just a line, a value somewhere, nothing more. At most one or two resources, and then suddenly you change from two deployments a week to 50 deployments a day. Definitely not the same thing, right? And for git-ups, looks exactly the same. Very tiny git repositories that are responsible for just one application in one environment. In here, for instance, you have a spring boot spin-up in one environment, just one git repository. It has, okay, one instance chart, a few config maps, and that's it, nothing more. So in the end, with these things we had in production, we're talking about a lot of machine, I handed up with close to 500 git repository. Was it a problem? Not really, especially when you have stuff like, I don't wanna make advertisement for them, but they do sometimes a good job, like GitLab. They are the only one to provide a logical container for git repository. I don't know why GitHub haven't done that already, but you can have groups, so you can create a structure of your localization, your environment, and then all this git repository for the things. And it works pretty nicely. I prefer having 400 trunk-based mini-repository than a giant mono-repository that I don't even understand the CI out of it, right? Okay, so that's all I had for you for tonight. If you've got any questions, feel free. Out is my Twitter QR code of my newly created Singaporean Twitter, so do not hesitate. I have open DM if you want. That's it. Should we, if you have a... No, no, he has a question. That's why I wanted to handle that. Sorry, I think we are waiting for the next speaker to start. I think we can hear about three questions, just three. Oh, we can do, yeah, sure. Thanks. My question is, how do you do production from the Zagis production with... If I'm not mistaken, there is a git repo. Yeah? Zagis in the group of production... So we have different git repositories, right? We have different subfolder, one for prod and not. And the thing is either at the beginning, eventhough it's gonna look very weird, but we did it manually, because what's you just changing into your repo in there? It's just a number of your image into your chart instance. But then after what we did in there, that was the first six months. And it was good enough, right? For three years, the first six months will proceed like that, no mistake. But then what we did is we wired from our CI directly a commit. And we would said the line, said an oak is always the great thing in IT. We would watch the line for the version and just get the we used to version or docker image with the chat of the commit. So we just put, replace this, and directly from the CI, so it's a technical user that would push the code. And it works very nicely. I'm gonna see if it commits the best on the site. I mean, you're doing like what commits to the station? Yeah, yeah, yeah. That sounds really good to me. It, trust me, it is, yeah, but it works. And it works pretty nicely. You need to start running it somehow. Yeah. I'll be, Gitlabs or GitHub, as they have really great API if you want to interact with them. Like you can create tons of technical users, tons of things. Okay. That's it. Just one last question. Anyone? This will sound weird as well. Do you have Gitlabs or serverless? So there is actually, I'll have a talk later this year about something called cross plane. So cross plane is this idea that you would use the Kubernetes control plane to provision your cloud resources. So you have, so you use the reconciliation loop of Kubernetes the same way flux does for a Kubernetes object for the cloud things. And it works very nicely with AWS. So you can provision your RGS that way. And every three minutes, every drift, still gonna be like replaying. So this is the next step for after infrastructure as code. It's called cross plane. You should definitely, should check the GitHub for this. That's it.


giving to them at no charge whatsoever and we think that by itself can be extremely valuable. Just being associated with a company like ours having SAP on their banner, we believe adds substantial value to it. We would love to for the right kind of startups, the marvel is to explore options where we could actually carry them on SAP paper and have our magnificent 25,000 person field team go out and sell to our customers. We're still a few months away from that happening but that would be a marvelous goal. What do you think is the biggest traction with this program? What's the early returns looking like in terms of that profile, kinds of companies? Well what we found is out of the 10 companies we're working with right now almost all of them are in areas which fall into SAP sweet spot of enterprise software but are very orthogonal use cases. They're very different from anything that we ourselves would be likely to look at but we think adds significant value to our customers. So that for us has been a big learning experience. Beyond that we see that for before the start of their POC stage they've actually built a Pufo concept and they have very big name customers who have already expressed interest in HANA and in their solution just based on this. So at the end of the day our very selfish interest in this is that build cool stuff other companies will want to buy it and when they buy it it will drive HANA sales along with it. Outside of resources what else are you guys getting out of this? Just kind of helping the ecosystem grow? Would you get a free look at the company?  We do have non-disclosures with the company but our goal eventually is it comes down. I mentioned it in a different context earlier it's the whole Betamax VHS story that we've got a great platform but unless we've got content on top of it which in this case are applications we're going to lose out in the platform game. We have to drive the message out there that HANA is a marvelous platform which does very very cool things but we need to have those applications on top and SAP even though we're 60,000 people cannot build all of them we need companies like this. And the startups you're working with are primarily funded startups they've received some kind of they range yeah they range between the seed stage and I'd say series A anything past that we feel that they get too big to really engage in this program anything less than that and we don't we don't think we're ready for that yet. There's been discussions around this go-to market exactly there is there is a program called the lighthouse program which is run out of the ecosystems group so this program is actually run out of Vishal's organization which is technology and innovation platforms so it's very much an innovation focused program these cells have always been very geeky on the cutting edge of things. Can we do that in a good way? Oh no no no I'm completely with you. So essentially what this is is kind of a peer community that you guys are putting together so to track the alpha entrepreneur so you can learn too. Absolutely we were actually in a meeting we were very fortunate to get a one-hour meeting with Hasso and Vishal last night and it was great because we came in and Hasso's admin told us he's really really tired he'll probably give you five minutes and then leave and you know Hasso himself is also very very technical he came in he started talking to these guys he ended up staying past his original time for an hour and a half and they they just were completely enthralled with the whole idea of what these startups are doing there's a specific comment that Hasso made when leaving the meeting which I thought is captured the whole idea he turned to Vishal and said Vishal what these guys are doing are three years ahead of what our customers would want to do so if we have to get a strategic competitive advantage we need to engage with them so that our product is three years ahead of what our customers want. Can you tell us which company well there are lots of companies who we love to compete with. So how do you you talk about the lighthouse program how do you hand off going from the the startup focus program to the lighthouse program. We don't actually hand off their two parallel programs aimed at two different demographics. Well I mean this is new so you're really not right this is brand new. Yeah I mean our goal is at the end of it what's your vision there because you said once they get to a certain size then they're sort of not candidates or is that different will you cultivate them through. Exactly our goal is to take them our our goal is to take them from from the very inception where they express interest in HANA to the point where they actually have a commercial product on HANA. Yeah okay how they grow the the company and organization beyond that is of course up to them. The lighthouse program is designed it's a great program is designed more for the larger system integrators and ISVs okay with more immediate near-term revenue potential. So there's no handoff you captured the flag when they hit achieve a certain mass and are out going to market and selling and working with you guys in the field. Exactly.  Exactly. Another startup okay good. All right listen we're getting the sign we've got to we've got to break a cost of thank you very much. Thank you David. I'm glad we could make this happen. Thank you very much okay startup program excellent idea obviously ecosystem is a theme Dave within SAP and we're bringing all the action to you from Orlando this is the Cube. We'll be right back with our next guest after this break.


Phuolang Pottery Village, located 60 kilometers from Hanoi, and Phuolang Ceramic Village in Kuevo District, Bac Min Province, is one of the last remaining villages in northern Vietnam that have been producing ceramics since the 13th century. Located in the Khao River, the ceramic village of Phuolang retains the simple beauty and peaceful atmosphere of yesterday here, with its narrow zigzag lanes, red brick walls, and then changing scenes of rural Vietnam, jars, vases lying the roads of the village because almost every family in the village makes pottery. So here we are in the workshop, they make the pottery pictures and you see Chiang Gom is a Vietnamese, Chiang picture and Gom is a pottery, and the name of the owner and they have a very nice slogan for that village, it means preserve the soul of the soil, that is slogan of the village. According to a book titled King Bac Habac, the founder of the pottery craft in Phuolang was Mr. Ly Phong Tu. In the Li Dynasty, Mr. Tu was sent as an envoy to China, where he learned the pottery craft. Back in Vietnam, he passed on his knowledge to the people of Red River Delta. It was at the beginning of the Trang Dynasty, in the 13th century, that pottery first appeared in Phuolang. Every single house in that village, they are the small workshop, they work at the small workshop with some workers, they make the stuff from the clay, they make it become the pottery. So in that village, every house they are going to make the pottery products for daily use, like the jar, the bottle, or the bowl for you to eat every day. Beside of the daily use products, they are going to make some things to build the buildings, like the roof and the ceilings and everything. If you go to the temple in Phuolang, Vietnam, you see all the roof with a very nice curve, they all make it with the pottery or ceramics. So now here, you can see the pottery painting. They make it all with the clay and the pottery. The artist, they are going to make the whole painting like that, with the whole clay. And then they are going to split it. You can see some crackles like that with their knife. And then they put it on the keel. They are going to put it on the keel and burn it for some hour, like another ceramic stuff. And then after that, they have a whole painting like that. It's so beautiful. It's amazing.

We had a lot of like team all obsidian last year. We didn't have a ton of the Not Don Russ. Oh, so glad Carbure connection has it up. Thank goodness So I will say you're supposed to get one contra per case. You've had three the white to nine That's contra we've had three of them.

Yeah, they said like it's probably one of the biggest mess you go Williams to 115 not even for us Hopefully they just needed those games to figure it out But I have a feeling that might not be the last of the yeah It might be a struggle from here It might be a dogfight Instead of winning by a few goals here. Just you're all of a sudden and hey Oh defense has been good defense and keeping has been good. We just can't score a Nougoloss De La Cruz rookie order wide numbered 15 of 20 on that blue flood or a blue edge a Son do the song be sweet Got bruhine Diaz the 199 triple jersey AC Milan got Gallagher to 75 cutting-edge dual Jersey Chelsea Next up is a huve to 199 Palo Sousa lightning strike auto There you go huve Palo Sousa I've seen some these old names You don't see another one's in an Anthony Alunga dual Jersey out of two different color jerseys there to 172 Man you yes, we've been balling.

Welcome to another vlog for my weird vlogmas. I don't know when this is going up, so hi I got this cute little like cycle bar Sweatshirt and a really funny thing about this is my first ride in Winter Park I saw this and I was like, ooh, I might get that after the class because I really like it and Then when I came out of the class it was gone So I took my first ride at this hamland location. It's in Winter Garden and They had these and I'm like, okay, it's a sign. I should just get it. So this is size small It's so cute and if you guys are wondering why I'm going to a different location I can go to these two locations like well not for free because I pay like a membership But I can go to them with like out any fees and stuff because they're owned by the same Franchise person. So that is how I can go to either one I'll probably end up coming to this one more just because of its location And I really am starting to think that I want to work out before work because after work I don't know. I just feel like I'm gonna be too tired. Also I'm gonna mail out Amanda's prez email you guys know I get her something every year It's just like a tradition. I got her some crystal goodies So hopefully she'll like them and then like put them in her little cottage thing that she has I've had these for a few months now. I can't wait to ship them out. I'm probably gonna do that now And maybe get some Starbucks Don't know if I'm going in the office Because we go we're supposed to be back in the office next Monday But right now like we're still at home So I don't know if my boss like wants me to go back in the office But if he does then I have everything like I packed this full-on bag of like dry shampoo like perfume change of clothes So yeah, I just need to text him but at first I think I'm gonna get some Starbucks. Oh, if you're not already it following me on Instagram. Make sure you follow me because that would be a really cool I don't know. I always forget to Remind people on to Starbucks. I think I gotta get in the habit of not going to Starbucks because it is extensive But there's one like right across the street. It's like really convenient. All right, so I got my Egg box here, and I will do a taste test of this little guy here I'll tell you what it is when I like about to try it But always eat before I drink so I know that's weird, but it's fine You know, you would think that I would actually use the car amount for its purpose So now I'm going to try this. This is a TI van SC Nitro. Oh tall vanilla, I don't know what the SC stands for but it's It's a vanilla Nitro cold brew. So hopefully I'll like it. I wanted to try something else just cuz Mmm, it's kind of bitter. I wish there was like some sweetener in it But it's fine. That's why I got the small version because like I knew I could Potentially not like it. It'll grow on me, I guess But now I'm gonna find a post office and mail that thing before I go home I don't think I'm gonna go in the office today. I guess I don't really know I'm just kind of playing it by ear but I'm gonna mail that real quick and then I Guess head home if I have to go in then it's fine Even though I'm like 20 minutes away right now instead of you know a longer Period of time now. I'm not making sense. All right onto the whatever I feel next. So this is actually growing on me I like it a lot. Don't worry. I'm gonna fix the hair Sam. I hate all these baby ears Like let me know how I can get rid of them. Anyway Growing on me, but I feel like I could use some sweetener a little too bitter for my taste But it is growing on me and it's a nice drink But I think I could only handle like one of them as a small version Because as you can see like I'm taking forever to drink this. I think I'm working from home today So I was gonna be pretty chill. Glad I got some footage today just gonna put some dry shampoo in the hail and Get started. Okay, so I got a fun package and I'm gonna try it on This is from hello Molly and if I remember I will link it down below of this video.

I think dress similar to this and ever since I saw that Whoa, this packaging ever since I saw her dress. I was like, I want one like that So I finally got one. I think I'm gonna wear it as like my Christmas dress Just cuz not that like I'm doing anything crazy or special for Christmas, but this is the dress So freaking cute it has one puffy sleeved arm and then it's like really like fitted to your body Then you have one arm that's like open I'm gonna try it on and see how it is and see how it looks and all that Jay has I'm excited Oh my gosh, I freaking love this dress.

Hey everybody, it's Tasos with RF Elements and today we're talking about antenna polarization. One of the most important parameters of an antenna is its polarization. It's a natural property of any antenna. Polarization dictates in which plane the fields of the transmission signals are changing. And polarization is dictated by a antenna designer. Horizontal and vertical are linear polarizations as well as slant or dual slant, where slant means that the fields are changing in planes rotated most commonly by 45 degrees relative to horizontal and vertical polarizations. Most commonly, antennas have linear polarization. That means that the field of the transmitted signals are changing in a line. The vast majority of antennas for WISP networks are linearly polarized. To achieve the best results, antenna polarizations must match. Horizontally polarized antennas communicate perfectly with equally polarized antennas on the other end of a link. As the rotation angle between antennas increase, the level of received signal decreases because of the physics of electromagnetic wave. This is why orthogonal polarizations provide isolation and creates additional communications channels at the same time. In the real world, isolation between horizontal and vertical is not perfect. Antennas with two polarizations have a parameter called cross polarization isolation, which tells you how well the H polarized antenna system and the V polarized antenna systems are separated. The higher the isolation, the better. For more interesting facts on RF and how antennas work, check out our future videos.


I think we're floating, aren't we? We must be still in the tank. We couldn't possibly... Oh, look who we are. Oh, thank you. What are all these people doing here? Thanks. Okay. Actually, we have two things that we're talking about. The first one is the Flotation Tank Association and we have a celebration with the FTA today because we're celebrating John Lilly's 100th birthday. This year is... That says 100th birthday year and there's a special event happening out. Can you all hear me? Okay. There is a book. The Gateway's Books and Tapes is out there in one of the vendors and they are publishing a book that John Lilly wrote in 1967 called Man and Dolphin. And when this is over, you can go check and ask Ivan when that book will be ready. But it's a very special book and it's very related to us in the tank world. The preface of the book is a double preface and I'm going to read this to you, which I have to because I didn't memorize it. It's a preface by Dr. Scott Taylor and he's the executive director of an organization that worked with John Lilly on citations for more than six years. And this is what he said about Dr. Lilly, Dr. Lilly was uniquely situated by birth and intellect to venture into multiple disciplines and was free to do basic research not driven by ideologies based on market concerns and belief systems. His family wealth enabled him to set his own agenda to pursue his lifelong question about the nature of reality relatively unhindered. So this is the character that invented this, what we'd all do. He was unhindered by what we all are hindered by and that's pretty amazing. And so we here have an association having to do with something that nobody ever heard of until two years ago when people started wanting to float more until now all of us are involved in getting people to climb into boxes of saltwater and float around and scientists are trying to figure out why it's so good for us. All these things are happening based on this very unusual character. And I think it's a very honorable character that we have to follow. In this book it's actually the story of the research of the communication project dealing with communication between humans and dolphins. And Key broke the rules of science which say that subject and researcher should be separated because what they did is the researcher and the subject live together for a year as they learn to communicate with each other and find ways of being together and that was the basis of John's work on language teaching dolphins to speak and communicate with humans. So it's pretty an amazing book. The last hundred pages of that book were dictated in the back of a VW van for two days straight and the time that was allotted for it was time that was dedicated to his research on tanks. So they've been united in a lot of ways. Anything you would say about John and when you first met him? Well he actually was floating around actually not floating but he was in the isolation tank and it was incredible for him. He felt wow this is amazing and he wondered if there was any sentient being that possibly was in a similar situation and he asked a friend of his and Fred said yes of course there is dolphins and whales in fact some of them have larger brains than we do and so at that point he decided to research dolphins for that reason and so he moved to the Virgin Islands and created a tank where sea salt was going I mean sea water was going through it and he so he was at the same time both researching the isolation tank and also researching dolphins. Amazing huh? He was on the first board of directors of the Flotation Tank Association and there was a meeting that we were at as well and somebody came in with a report that there was centers out there where the water was dirty where the temperature was way too warm and where women were being harassed. He got pretty pissed off about that and he said we don't do that clean it up as fast as you can and we did. He said that kind of a standard for us that we do what's good we do the right thing and we keep to best practices and that's the second point of what FTA needs to take care of. The first one is to start talking to each other to have information that's sent out and we have a website flotation.org to take care of that. I have a code for you to use in order to get in on it and I'll tell you that at the end of this but FTA needs to have a communication system and I think we can do it on this website and one of the things that all of us here you know this is a very smart group of people and very talented and you all can contribute to FTA by inserting things by putting things onto that website and you'll find out how to do that and also to have major communication among us is a very important thing and the last thing is what was the last point Glenn? The research. The research, right. And we heard that FloatOn is initiating the research to raise money so that what happens to the solution that we're floating in in order to find out we're starting with basic research of what happens with Epsom salt and water and I think that was mentioned in the talk this afternoon and in order to find those things out it requires a lot of lab tests. I think the numbers I heard, two of them, that we need to raise somewhere between $17,000 and $30,000 and the way that's being raised is by donations. We're having you join those who will when you join FTA at the booth, I think it's out there, you get a 20% discount today and 30% of what you pay is going into that fund to pay for the research that we need in order to find out what is affecting the water, what's the best way to have the water working. Mention what Shoshana has done. The person who's really been behind all this happens to be my daughter, Shoshana. Are you here, Shosh? Okay, anyway, she's the one who is behind raising all the money for Justin to do that research project and she knocks herself out getting tablecloths for FTA booths and doing all that kind of work and she's just been doing an absolutely fabulous job. So all of you who can and want to, please join FTA today or if you can't get to it today because this is running late, it'll be open all day tomorrow. You can just be out there, there'll be somebody at the booth all day long and we'd love to have you join us and keep this thing going. It's a big job we have to do and let's have a good time at it. And if you don't want to go to the booth to join, you can join by going to flotation.org and the word float is at the beginning of it so it's spelled F-L-O-A-T-A-T-I-O-M. Okay, thanks.


In this video, I will describe how each of the following works to regulate reabsorption and secretion to affect urine volume and composition. The renin angiotensin aldosterone system, antidiuretic hormone, natriuretic peptides, and parathyroid hormone. Aldosterone is a steroid hormone that is secreted by cells in the zona glomerulosa of the adrenal cortex. Aldosterone is also known as mineral corticoid, and it binds to an intracellular receptor known as the mineral corticoid receptor. The stimulus for the production of aldosterone is the renin angiotensin mechanism leading to the production of angiotensin II. Angiotensin II binds to receptors on the surface of cells in the adrenal cortex in the zona glomerulosa and then stimulates the production of aldosterone. However, angiotensin II is not the only stimulus for the production of aldosterone. An elevated plasma potassium concentration, also known as hyperkalemia, is a stimulus for aldosterone production. And another hormone, adrenocorticotropic hormone, commonly abbreviated ACTH, is secreted by the anterior pituitary gland in response to stress. And ACTH can also stimulate the production of aldosterone. Here we see a summary of the renin angiotensin aldosterone system, starting with the kidneys releasing renin into the blood. This would occur in response to a low sodium concentration of the filtrate. Renin will convert angiotensinogen to angiotensin I, then angiotensin I is converted to angiotensin II by the angiotensin converting enzyme in the lungs. Angiotensin II binds to receptors on the surface of cells in the zona glomerulosa of the adrenal cortex to stimulate the production of aldosterone. Then, aldosterone binds to the mineral corticoid receptors in the cells of the distalconvoluted tubule and collecting ducts of the nephron, leading to increased sodium and water reabsorption. Aldosterone works by binding to an intracellular receptor, known as the mineral corticoid receptor, and stimulating increased transcription of genes for the epithelial sodium channel and sodium and water reabsorption. The epithelial sodium channel enables the facilitated diffusion of sodium from the filtrate into the epithelial cells of the distalconvoluted tubule or collecting duct. The sodium potassium pump enables the facilitated diffusion of sodium from the filtrate into the epithelial cells of the distalconvoluted tubule or collecting duct. And then the sodium potassium pump enables a primary active transport mechanism by increasing the expression of the genes for these proteins. An increased number of sodium channels and sodium potassium pumps leads to an increased rate of sodium reabsorption. And at the same time, this will lead to an increased rate of potassium secretion. So the stimuli for aldosterone production are increased blood potassium or low blood sodium levels. And as aldosterone has its effects in the kidney at the distalconvoluted tubule and collecting duct, it leads to potassium secretion and sodium reabsorption, helping to restore the homeostatic concentrations of sodium and potassium. Aldosterone also works together with another hormone known as antidiuretic hormone. The secretion of antidiuretic hormone is regulated by osmoreceptors of the hypothalamus, which are neurons sensitive to the concentration of solutes. In response to a high solute concentration and a high osmolarity that is detected by the osmoreceptors of the hypothalamus, antidiuretic hormone is released from the posterior pituitary gland. And then travels throughout the body in the blood. But when antidiuretic hormone binds to receptors on the surface of cells in the distalconvoluted tubule and collecting duct, it will stimulate watery absorption. So by stimulating water reabsorption, antidiuretic hormone can work to increase the blood volume and decrease the concentration of solutes in the blood, helping to maintain a homeostatic osmolarity of blood plasma. So while aldosterone will stimulate sodium reabsorption, antidiuretic hormone stimulates water reabsorption. But reabsorption of sodium will create a driving force to help fuel the reabsorption of water as increasing sodium reabsorption creates an osmotic driving force that will fuel further reabsorption of water. So both aldosterone and antidiuretic hormone can work to increase water reabsorption to increase or help maintain blood volume. In response to dehydration, we typically produce a small volume of relatively concentrated urine, whereas if we're very well hydrated, we'll produce a larger volume of more dilute urine. And this works to help maintain water balance in the body. If the blood osmolarity becomes too high, this will be detected by osmoreceptors in the hypothalamus that stimulate the secretion of antidiuretic hormone. This will also stimulate thirst, leading us to go find a drink in order to increase the amount of water intake to help restore water balance of the body. At the same time as antidiuretic hormone will have its actions in the kidney to help produce a smaller volume of more concentrated urine. A decrease in blood volume can also lead to decreasing blood pressure. And this is a stimulus that will then lead to the activation of the renin angiotensin aldosterone mechanism. Angiotensin 2 will have a widespread effect through the body of vasoconstriction. Similarly, antidiuretic hormone causes vasoconstriction as a mechanism to help increase blood pressure, maintaining the circulation despite a decreasing blood volume in the state of dehydration. Osmoreceptors found in the hypothalamus are neurons that produce antidiuretic hormone and have their axons extending down into the posterior pituitary gland. In response to a high osmolarity during dehydration, osmoreceptors will secrete antidiuretic hormone into the blood. Here we can see the major effects of antidiuretic hormone. Antidiuretic hormone is produced by osmoreceptors of the hypothalamus and released from the posterior pituitary gland. Then, antidiuretic hormone binds to receptors on vascular smooth muscle cells, causing vasoconstriction to help increase total peripheral resistance and increase blood pressure. Then, antidiuretic hormone also has its effect in the kidneys to stimulate the reabsorption of water, producing a small volume of concentrated urine. A synonym for antidiuretic hormone is vasopressin, and this synonym relates to the fact that antidiuretic hormone has an action of stimulating vasoconstriction. Aquaporin channels are proteins that enable facilitated diffusion of water. In response to antidiuretic hormone, the epithelial cells of the collecting duct and distal convoluted tubule will increase the number of aquaporin channels. This increased expression of aquaporins is responsible for increasing water reabsorption, leading to the small volume of concentrated urine in response to antidiuretic hormone. The atrial natiuretic peptide will also have an influence on the reabsorption of sodium and water. If we are very well hydrated and have a very large plasma volume, this can lead to stretching of the heart, stretching of the atrial chambers of the heart will lead to increased secretion of atrial natiuretic peptide. Then, ANP will inhibit the renin angiotensin aldosterone system, also inhibit the secretion of antidiuretic hormone, and have the indirect effects of decreasing the reabsorption of sodium and water as a result of inhibiting the signaling of aldosterone and antidiuretic hormone. This will lead to an increase in the urine volume and a decrease in the concentration of that urine. Parathyroid hormone stimulates the reabsorption of calcium in the distal convoluted tubule. Parathyroid hormone is secreted by the parathyroid gland in response to low blood calcium concentrations, also known as hypocalcemia. Parathyroid hormone will bind to receptors on the surface of cells in the distal convoluted tubule, stimulating calcium reabsorption, and also stimulating the activation of vitamin D to the calcitriol form. Calcitriol will then function as a hormone that stimulates calcium absorption in the intestines.


IT, FIT and ITIL are complementary and they can be used together very well. ITIL is the most widely used service management practice out there today, used by many operations and support teams. However, with the emergence of new practices such as agile continuous delivery, DevOps, but also cloud management, traditional service management practices have been challenged for their relevance. In this new digital reality, we have to focus on end-to-end workflows, collaboration with the business, automating IT activities, enabling full service lifecycle management of planning, building, deploying and operating IT services. To remain relevant and grow your personal value, you as a service management practitioner need to understand the bigger picture, how everything fits together. And that is what IT for IT can help you with. IT for IT provides a blueprint for a modern IT operating model, helps you to combine ITIL with new modern practices such as DevOps and continuous delivery. In a new digital enterprise, IT management is becoming a critical capability. You as a service management practitioner can become a critical asset. If you are able to combine your ITIL expertise with new modern ways of thinking about an operating model, combining IT for IT with ITIL. Using IT for IT and ITIL together, you can prepare your IT organization in this journey to manage the new digital enterprise.


I'm so sorry. Sorry? I'm so sorry. I don't know what you're doing to me.


good morning from california it is 10 18 a.m on sunday february i almost said 20th we are headed home from the baby shower we made a stop in hildsburg so jenny adopted daughter could see her grandmother who's not doing well um and they're off doing that bob is looking for the restroom and then we're gonna call a friend of ours and check in on them because she's not a friend of ours is also not doing well um we're gonna head home today we're gonna make a couple of stops i've gotten some beautiful video and pictures from the car of this beautiful farm country in the middle of california there's some beautiful farm country here i don't want to live here but it's a pretty state um anyway i'll insert some video clips and or pictures here okay so i also did a shopping trip at daizo which is buried under there we are buried in baby gifts back there can you see that yeah um and i got some things at daizo that was fun for those who don't know that's a japanese dollar store um they have them in california and they have them in a few other states but not oregon so when i come to california i try to go to one um so i picked up a few things there and um some snacks and some other things i have trouble finding in oregon and we're gonna make a couple more stops before we leave the state and head home so uh yeah and bob has tomorrow off which might be good because we have to get ready for the baby shower at our house and we have to get that stuff to the kids house so many things so anyway all right i think that's it for the minute i'll be back guys good morning it is monday not january holy cow february 20th i believe let's see 10 37 a.m um anyway while we were in california went to daizo and i don't do hauls anymore because i don't like feeling making you guys feel like you have to buy stuff you don't but i'm sorry i dropped something i do want to share what you can get at some place like a dollar store to use in your art and um yeah so daizo is a japanese dollar store it's actually not a dollar never has been over here it was a dollar 25 now thank you inflation it's a dollar 75 um anyway i picked up some things to make painting marks with which no matter what dollar store i'm going to is something i always do when i'm doing abstract painting like i've been doing like that i do use paint brushes but i more often than not don't use paint brushes so i found a couple of um tool this is actually a hairbrush um i wouldn't use it on my hair necessarily not because there's anything wrong with it but i mean i can see scrubbing this over the paint and what that would do i found this is a brush for cleaning your shoes it looks like a nail brush so that'll be fun and then i found this one i won't take this off of here this is another shoe brush shoe brush for cleaning the inside of your shoes evidently and it's got these bristles here it's got this pointy end with some teeth on it so that'll be fun to play with i found a folding clipboard which i've kind of been walking wanting but they're too expensive um and this is a plastic one but i want to try doing a very small urban sketching thing with a folding clipboard so i got this to try it it was dollar 75 so um i found some double sided tape i needed some more i'm going to be working on a scrapbook for the grand baby to be uh aka jr this is youtube name um and yes it's a hymn um i found another mini dustpan and brush i do have one that's a bit bigger than this i use in the art room all the time um i got another one because that we use it upstairs and down um i found some stickers i didn't really need them but you know they have really cute stickers at um daizo almost always i and i'm really into botanical things right now and i found these floral ones i found these two i got two of these i found these this is some kind of tape says remake tape and it says leaf pattern but it looks to me like an art deco inspired pattern i got two of them i don't know if i needed two but they have lots of like little mini note cards and envelopes there always and i do use them in some of my journals and things um and so i got two they had this one with a feather pattern and they only had one of these or i would have probably gotten two of them and then they had this one with just lined note paper and then some different colored solid colored envelopes i did get a chopstick rest because i want to use it actually for our brush rest i got a metal one and they had this cute um sticky note box it's a sticky note storage box i didn't really need it but it was cat it's cat themed it's so cute um so they have this they had it in different colors i got the white one it has notes in it and then i found some of the associated sticky notes with the black cat on them they're just so cute i didn't really need them but anyway um daizo does have a website i do think you can order and have ships from their website i don't know that everything will be on the website it isn't always but i will link the website down below um you may have a different version of a dollar store near you whether it's dollar general or um dollar tree or what's the other one five below um or you may have daizo or there's another version of daizo um i know from shannon green that was in texas and i don't remember the name of it um but anyway if you have another source for this that you never maybe go to go check them out you might not find anything um but you might find some you know cute stuff and stationery is expensive so one of the main things i get when i go there stationary so anyway all right i have lots of stuff to catch up on today now that we're back and things to put away and the baby shower here that we're gonna have next week to get ready for so that's all i think all right i'll be back morning it is 11 16 a.m on tuesday february 21st and i still have a lot of catching up to do i've got to clear off my desk i'm working on laundry um the table behind me is full there's just a lot to do plus i'm going to be filming the tool desk for the fixing the flow in your art room series so yeah and i'm having trouble getting motivated to do that desk i'm not exactly sure why but anyway i'll work through the video stay tuned um anyway i forgot to write yesterday's social media posts because there was just a lot going on yesterday and we just got back from the california baby shower so and getting ready for the next one that's going to be here on this coming saturday so anyway i'm going to write the posts now try to get some stuff put away and cleaned up and then biting the bullet and get the filming done i'll be back okay guys we filmed a fixing the flow video installment number three i have to edit last week's vlog but i'm i'm gonna go do some cleaning downstairs first the vlog might be late if i don't get it edited tonight so i don't know we'll see but i think i'm gonna put my earbuds in i'm gonna place some youtube or my soap opera or something while i clean the floor because i'll be back by vlogging today i don't think so it is wednesday february 22nd 207 p.m well you know i started off the morning with an early morning counseling appointment and let's just throw the schedule off after that um got some stuff cleaned up here in the art room got some photos printed for my watercolor sketchbook which i need to start back on and i think i'm gonna do another one of these really quick i've got to take this off and otherwise i'm just having a lazy day enjoying my space not necessarily creating anything in it but enjoying it nonetheless it is rainy outside and cold we have a slight chance of snow although right now all i see is wetness i need to go check the mail but i'm dreading going out there not because i'm worried about getting wet because it's cold out so anyway exciting i know i've got video to edit but i don't really want to do right now so anyway all right i'll be guys can you see that yeah that's not rain it's snowing okay i had to turn the fireplace on to help the furnace warm the house it was only 66 in the house that's cold and oh yeah it's been snowing on and off but now it's starting to stick i have to admit i'm not mad at it okay you guys i literally just woke up i look like a hot mess and oh my god yeah it snowed some more last night and let's just say it was more than an inch hold on that's a lot of snow wow okay you guys it's 11 30 ish we still have quite a bit of snow outside so i was guesstimating we got about four inches but weather reports reporting that portland got 10.8 inches we are southwest of portland so yeah anyway it's pretty crazy outside hang on do this quick because i don't want to be outside long that shit's cold outside it's only 29 degrees i think hold on yeah it's just a little cold and it's been windy on and off and it is not melting and my poor car holy cow i'll show you guys the parents next door with the two little ones are pregnant again and they just asked me to set up their gender reveal uh things no pressure oh my god i'd have bob help me because i had a little mini anxiety attack about it and getting it worried about getting it wrong but anyway they don't know it yet but they're having a boy must be the year for boys anyway so that's all started holy moly all right i need to go upstairs and do some art or something calm my blood pressure down a little bit i'll be back i would say good morning but it's after lunch it is friday february 24th it's 12 47 p.m i have already gotten some artwork done and some paperwork filled out for my daughter which i needed to fill out and i needed to do without any mistakes and it's taken me three times but i got it now i gotta get it notarized anyway um we're supposed to have the baby shower second baby shower here at the house tomorrow it's not going to be a whole bunch of people i'm but i'm hoping it's some people because of the snow um it has started to melt a bit it is taking it sweet old time melting though so if it doesn't all melt before it starts getting cold again tonight i don't know it's i don't know anyway i guess we'll see if it's not one thing it's five others i know i'll be back is that better that's terrible anyway it's uh just about 330 i think we're as ready for tomorrow's baby shower as we can be the snow is melting thank goodness um a few more things i need to sort of put away hide in the master bedroom that sort of thing before we go to bed tonight but otherwise we're pretty good we've talked to both bob's mom and a friend of ours who are both not doing very well health wise in the last 24 hours and could use some good thoughts at their way if you don't mind anyway i've done some artwork for the day i should do some computer stuff to get ready for march first which is next week but you know what i just don't have the brain power for it right now so all right i'll be back almost six o'clock and i haven't logged all day today because there's been a lot going on so it was second baby shower day and uh baby shower is down it went really well we do have some extra party favors in decor but we know at least two other people that are heavy baby boys so anyway we'll make it work we are headed obviously in the car out to the grocery store tonight even though it's a bit late for saturday to be shopping because we might get more snow tonight and if that's the case we're not going to want to drive tomorrow 11 inches of snow in the area where we live we're expecting somewhere between two and seven more inches sometime tonight if you have questions comments or concerns leave them down below i do answer all my comments you can leave me uh send me happy mail my address is down in the description um patreon is down there if you want direct contact with me i am helping a few patrons out with um fixing up their art rooms and uh yeah that sort of thing so anyway i think that's it for a minute my brain is just on overload can you tell anyway go out and have a great day have a great week do something nice for yourself because you deserve it and i'll see you next week bye guys
