You guys kind of know the drill, type OG in the chat. Also, you guys play a big role in making sure that we grow this room as big as possible. So just share the video if you can, share the links in the comments for anything that I'm talking about. You guys know what it is, the tools, everything that we're using. Also, I'm live on Minerva Beauty's Facebook, the Freeslawn Education Facebook, and also our YouTube channel. So I'm super excited to be on all of those platforms. And yeah, that's it. So let's get in here, get involved, start chatting, guys. Let me turn the music down a little bit. So before we start the class today, I wanna say hello to everybody. So hi, Juju, what's up? Good to see you in the chat. Now, we're gonna do a short haircut today. I'm gonna walk you through it step by step, show you guys how to do it. But the other thing is I'm giving away my pair of Mizutani DB20 scissors. It's a $950 scissor. My son shaved his head yesterday.  He was able to raise about $6,000. We did that over the last couple of weeks for childhood cancer research. So he shaved his head and I'm giving away one of my prize possessions, which is my DB20 scissor, which is right here.  Maybe I'll do one last haircut with it today. It's including a free sharpening. So yeah, maybe I'll do this haircut today with this scissor just as a final farewell.  So I'm gonna draw the name now so you'll know who it is. Let's see. But let me just say hi to you guys for a second as well. Let me pop here. Who we got in the chat today? Karen, good to see you. I got your name in the drawing today. First class I'm actually able to be here for. Billy, that's awesome. Thank you. Welcome, welcome. Let's see. All right guys, we're getting people logged in here. Awesome, very cool. All right, so let's do the drawing. Let me go here, that, go back. All right, learning new things. Awesome, very cool. All right guys, so here we go. I got a whole, my backup hat, a backup hat full of names here. So all of you guys that donated $10 or more, your name went in here. And now we're gonna draw the winner.   Let's see where we're at here. Just look like I looked. So I'm gonna mess it around some more. Hello, hello, hello everyone. All right, ready? The winner of the scissor. This one jumped into my fingers. Steffi does hair. Steffi does hair. Difficult.  Oh well, Steffi does hair. Congratulations, Steffi. I will be contacting you on Instagram today. You won the DB20 scissor. Thank you to everybody out there that did help and donate to the cause all of your money, even though you didn't win the scissor, only one person can. Actually, I gotta choose a tri-raiser winner as well. But all of you guys, all the money that you guys donated goes to a really, really good cause, which is 100% of it goes to childhood cancer research. So thank you guys for that. We'll do it again next year. We'll see what I give away. Maybe even my car, maybe that, I don't know. I at least thought I can't give that away. All right, so yes, congratulations. All right, so we got one more drawing, one more giveaway here. And that is for a tri-raiser, which I'm gonna be using today. I'm not gonna use your tri-raiser for this, but I'm gonna be using a tri-raiser in the cut as well as the DB20. But here is the tri-raiser available on Freeslaw and Education. They're $44.95. If you wanna buy one, go to ShopFSE. But if you donated, you have a chance to win. So prize number two, maybe I'll give away some more stuff today too. We'll see, see how I'm feeling. Feeling in the giveaway spirit today. All right, this one jumped into my hand, Jess Mack. So I don't know if she's on here right now, but Jess, congratulations. I just picked the most expensive place to ship a tri-raiser to, which is Australia. Yay. So congratulations, Jess. Thank you so much for your donations. Actually fun little story, Jess's son. He actually went out to do some work. Her little son to raise money for, to donate to my son's charity and head shaving and all that. So super cool. Congrats, Jess. You got a backup tri-raiser for you. Give one to a friend if you want or just keep it for yourself. Thank you so much. All right, here we go. I'm gonna give away some more stuff throughout this to those that donated and maybe to one of you guys who are watching live. So we'll see how it goes. All right. So, let me get into this here. So we're gonna be doing a shorter haircut on the mannequin today. I wanna go kind of pixie style. I have this thought in my head of kind of a fringier, almost short mullet, but not a mullet, but like fringier around the edges. So I wanna cut that today. I've just had this thing pictured in my head. Hopefully it all works out, we'll see. But I'm super excited to just try it out with you guys, have some fun with it. We'll talk about structure. We'll talk about different things. Also, if you guys have questions, type Q in the chat. Put your question. I can see the chat all up on the board. I can see you guys going through. So there you go. So if you have questions, type Q, put in your question. Otherwise, let's get started and have some fun. All right, so let me get to the closer camera here. And then I'll put this one up. So first things first, here is the mannequin. Now she's got a little bit shorter fringe. So I gotta keep that in mind when I go into this shorter haircut with how I want the outcome to be. But we're gonna go through in section. Now I'm gonna break down the way that I wanna section this off because if I'm gonna do kind of a fringier feeling around the edges, then I may want to think about that when I'm going through my sectioning. So a couple of things. I've got, turn the head here. So first I'm gonna section off the fringe. Then I'm gonna move into sides. Fringe will also include a little bit of the top. So what I'm gonna do is I'm gonna draw kind of from the apex or the high point of the head. I'm gonna draw that down to the corner of the eyebrow. There we go. Nice little slight diagonal forward line. And then I'm gonna do the same thing on the opposite here. Over here, draw from the high point down to the edge of the eyebrow. So that is our fringe section. I'll comb this up in a way.  So on the curve, it kind of goes down. So I want to be aware of that as I'm cutting the top of the head. You can see how from the high point, it's all kind of downhill from there, right? So I'll add my clip in, keep that sectioned away. Now, both corners right at this point are both sitting more centered. So both corners are sitting right around that parietal ridge area. So that's kind of where I want it to be. So if I go from this point, there, I'm finding myself, finding myself here. There's the top view. All right, so from this top view, you've got your back crown area. So high point of the head, and then as it rolls back, you've got high crown, and then you've got mid crown, right? Kind of if you drew a circle right around this crown area, that would be the middle, right? And you've got low crown here. So what I want to do is I want to go just under mid crown or the center of the crown. So make sure you got a nice clean vertical line back, then comb the hair around the head and get it moving in the direction you want to take your parting. So I move it around the head this way. Once I get it clean, it's easy to comb through. Then I take underneath the crown and I work around the head to that point, just like that. Now I'm going to take this section here, twist it away. Twist it up nice and tight in the clip. The same thing on the opposite side. So work around the head and then draw from that mid crown around to the edge of the eyebrow. Twist it and clip it. Chris, Q, what is the crown area? So the crown area is, I mean just imagine kind of having a crown on your head. That's what I always think about. So it would be a circle area that sits back on your head. So you could kind of take it from the apex. So if I look at, see if I have a bald head, I do. It's a good lesson for all of you guys out there, especially students that are watching. Look, it's a blue day. So, pop this off.  All right, so those of you guys out there, as we look at the head, right? So the head is a nice round surface. Once it's got hair on it, it kind of hides some of these curves and movements. So I want to show you guys and kind of break down some of the head shape. So this is how I think about it. There's definitely technical bone structure names and I use some of them. And then sometimes I get a little looser with that with calling them the names, right? So here we go. So you go here. We look at the side of the head. Now look at this round surface. So we start here. This is the nape, right in this area, right? So you've got the nape and then as you move up the head, you get to the occipital bone or occipital bone, however you want to say it. I'm sure there's a definite right way to say it. I say it occipital, but I think it's occipital. I don't know. So gets the job done. So I shouldn't be better at that, to be honest. Now that I'm thinking about it. So here it curves up, occipital bone there, then we get to low crown. So the question was what is the crown? If you look at where the crown would sit on somebody's head, this is the crown area. So this circle that sits in the back of the head. So imagine drawing this kind of crown shape. I always refer to that as the crown. So if we're at high crown, we're here. If you're in the middle of the crown, then you're obviously right where this kind of magnet is. And then if you're in the low crown, you're just above the occipital bone and in the crown area, right? So you move from the occipital bone, which is right here in the back, and then you move into this low crown area. Then behind the ear or mastoid process, I think this is called, I like to just say behind the ear. And then you've got your temple area here and then your fringe area and then you've got the high point of the head, right? So crown, high crown sits just about here in my opinion. So it's just about here. And then that little bit above it, so when you see where the comb starts to go away from the head right there, this would be where your high point is. That's the highest point of the head. So if I put the comb down here, it leaves the head there. So that kind of rocking motion will show you where that apex is. So it's important to know where the highest point is. She's from the matrix, yes. These are actually things that are feeding her brain. I've never seen the matrix, so I don't even know. All right, so that's a breakdown of the head shape. Hopefully that helps you guys as we work through it. Oh, and then the parietal ridge, which I didn't go over, but I can show you guys. So parietal ridge is basically what separates the up and down. So right here, this little ridge, this bone, kind of where we took this line from, that's the parietal ridge. You can find that by holding the comb up against and then finding where that kind of rocks back and forth as well. So there you go. There's your lesson for the day. All right, thank you, Juju. I appreciate that. I really appreciate it. It's very nice. Okay, hello, France and Anne. Hello, Anne from France. Vicki says she thinks I say occipital bone correctly. I don't think, it's too seized, so I'm imagining it's occipital, not ox, but I don't know. Everybody will say like I'm either right or wrong, but they probably just heard it from somebody too. So maybe there's like an English person, English major that could explain to me how to pronounce it. All right, so I'm gonna use the DB20 because it's just nostalgic and I wanna use it in this haircut before I send it off. To our winner. But I didn't really plan on using a scissor today. I was gonna just use the tri-razor. So I'm gonna work it in probably more towards the top, but that'll be kind of how we do that. Or maybe at the end I'll use it up. I'm definitely gonna use the tri-razor today. So what is the tri-razor? Here is the tool. I think if I hold it back here it'll probably just be better. So it's a razor tool that has three razors in one. So it's got one side that cuts 100% of the hair. It's got one side that is a texture 25, so it takes out 25% of the hair. And then you've got 50% of the hair coming out on this side. Now this is a tool that it's patent pending. We created it. There have been, I think I'm learning that there was a triangle razor 20 years ago I guess. I didn't know, but it's not the same thing. So those of you guys that see this and it's not the same thing. This we designed from nothing, from scratch. To create the three sides that cut differently. And it's just super cool. It's super fun to use. And I love hearing everybody's stories about the cuts that they're doing with it and showing me on Instagram and stuff. It's really awesome. So if you guys are looking to pick up a razor tool I love it if you go to our shopfse.com and you can pick up the razor. Anywhere in the world. Akzip Pitul. Catherine says, Akzip Pitul. If you refer back to a haircut you did in the past can I search for it on the website or app? Yes you can Karen. That's kind of the point of the app is we're trying to load all the content on there. Also make simpler versions of the content on there. Then make it searchable for you guys so that it's an easy tool that you can have in the palm of your hand.  So that's kind of the goal there. All right, I know too much chatter. So just so you guys know, all these classes I'm really filming a tutorial to put back on YouTube or Facebook, a shorter version of these. This is really for me to have fun interact with you guys cut hair live, take your questions and just do that kind of thing. So if you're looking for the shorter versions of these cuts and me not talking so much the videos are great for that. All right, so here's what I'm gonna do because I really just wanna draw this shape in and I wanna have some fun kind of cutting this shorter shape into the longer kind of fringy area. So what I'm gonna do this is kind of the thought that I've been having. So let me section off the front and back as well. So that's gonna be the only other sections that I put in this. So right here, we're gonna split front and back. I wanna go right to this hairline area, just like this. There it is. And I'll clip that back in a way. Actually, let me get that tighter back. Really get it out of the way. Okay. So now what I'm gonna do is using the tri razor and using over direction, we're gonna create a really fun fringy effect. So what I wanna do is I wanna lift this hair. So I'm gonna comb it up and I wanna get it nice and tight at the occipital bone. So my finger will then be level with the occipital bone. So just like this, comb the hair up like that. Now you don't want it to be low because then you're not pushing weight and length down. I wanna make sure I elevate up. Get this hair nice and tight into my fingers. And now I can decide. Now how do I want that weight to fall? Do I want it to fall square? Do I want it to fall, comb it more like this and make it fall, push more that way, like diagonal forward or do I want it to go more diagonal back? You can really decide. I want it to go more diagonal forward. So I'm gonna comb this up in the air just like this at that occipital bone area.  I wanna go to the top angle so you guys can see this better. Comb it up. Now if I want it to go diagonal forward, I go back to this back corner here. I want it to go diagonal back and I go to this front corner here. And if I want it to be square, I go square to the parting like this, right? So I want it to go diagonal forward, push that weight towards the front of the face. So I'm combing this hair up and now I'm gonna work my tri razor across this section, this like this and create a line. So now let me show you guys what happens. Here it is. So when you comb the hair down, see how it gets fringier around the edges and it keeps that length, that's the goal. So I can always cut into that later but it gives me that kind of length to play around with within this cut. So now we're gonna do another similar thing. We're gonna do it on the other side. Same motion there. Jess, I see your message. That is very nice of you. We can do that. We can do that for sure. I already commented about how I just picked the most expensive place to send it to. That's how you know our contests aren't rigged. All right, so right here, split front and back just like that. I will clip it away and now combing this hair up to the back corner just like that. Get it nice and tight.  See how I'm combing this up like this? It's a little filming 101. I comb this up like this. Hold it there like that.  Fun facts. All right, diagonal back to that back corner and then I work the tri-raiser across just like that. And when we comb it down, and comb it down, we get our nice, fringy, fun area. Check that out. Okay, now we're gonna take a triangle section out of the back. So right here, and there's a reason for this triangle section, but I'll explain in a minute. So you're kinda just taking some of that crown out. So from basically this point here, I'm gonna come down that. I'm gonna do the same thing on the opposite side. Connect those two together here just like that. Now I'll check my triangle, make sure it's good enough. Looks good enough. So where are you guys watching from? Why don't you let me know in the chat. Can we do the same cut by using a scissor? For sure, yeah. So I love the look of a razor because it's just so soft, the lines. You get a little bit more of a blunt line with a scissor, but you could point cut, so that would kinda take away some of that. But you could definitely condense cut with a scissor. Depends on the hair texture too, or the hair density. So if it's super thick, you might not want to go in and like, you might wanna use a razor just because it'll help you out. OG from, oh, Adele, what's up, Adele? Rhonda, good to see you, Lexington, Kentucky. Awesome. Maryville, Tennessee, Karen Gibson. Good to see you, Karen. Janice Vicky from the UK. Amanda, Louisiana. Jessica, New Orleans. Rhythm from India. Adrian, Iowa. I went to beauty school in Iowa, Adrian. What part of Iowa are you in? All right. Brownsville, Texas. Johannesburg, South Africa. South Africa's on my list of places I would like to go.  I should show you guys what I just did. That would be nice. One sec, let me do it again. When they release us from this whole quarantine, COVID stuff, like, is everybody just going on as many vacations as possible? Like, they never know when they might get locked down again? That's kind of where I'm at. As soon as they release us, I might quit working. Just forever. Just stop.  All right. I forgot, my tires are just in my pocket. All right, so now I'm gonna do a very similar technique that I did in the front. So, pretty cool because this is basically making pixie cutting very simple. And that's kind of what I'm all about, is figuring out ways to simplify and speed up the haircutting process so that we get better results in faster time. Hair dressers can make more money. That's the deal. So, what I'm gonna do is now I wanna go parallel to the parting. So, I'm gonna comb all this hair up, and you might even break it up into a couple sections so I could start here. I'm gonna go parallel to this parting and keep the elevation right about at the parting, right? So, let me pop over here. Yep, so what I'm gonna do is I'm gonna elevate this entire section, and then your guideline comes from what you previously cut. And the tires are just in my pocket, so just like this. Just make sure you get the root nice and tight, carve across, and when I comb it down, I'll show you guys the whole thing, but actually, I'll cut that one. In front of you, I might get in the way a little bit, but that's okay. There we go, right above that parting. Now, what I want you guys to think about while you're watching me do this is over direction and how much of a role it's playing. It's playing the entire role of how this haircut's forming, right? So, am I gonna leave this tail? No, I'm not going to fully, but if you wanted to, if you were Miley Cyrus, you might. I'm not gonna leave it, but that gives me a ton of hair to play with in the end result. So imagine now, if I come in here, and I'm gonna do this in a minute, but I come in here with the tri-raiser and I just start taking some of these pieces shorter. Now I've got this little shaggy pixie with a fringy edge that doesn't look moldy. It just looks more fashionable, right? So the same thing over here, keeping the hair, gotta keep it saturated, you know what I'm saying? Already digging the look of this. I'll take just a subsection of this panel. I'm not gonna take it all because it doesn't all fit in my hand. And I just comb this hair up, take a little guide from the previously cut section and get this section comb nice and tight at the base and elevated to the parting of our triangle up here. So right there, my guide is right there. See, super cool. Rhythm, you gotta order one, it's the best. This is my favorite tool ever to cut hair with.  Cut people's hair wherever you're at. If I move to an island after COVID, if they release me and I move to an island, what's the one thing I'll bring? This. This tool. All right, that looks super cool already and honestly, you could leave it like that but I'll go into it, cut into it a little bit more. Again guys, if you wanna get a tri-raiser, maybe I'll give one away, so stay tuned, stay with me here. But 44.95 has three blades inside, comes with three blades and a pack of five blades in a nice little box like this. We spent lots of time making the box look super cool. So you get the five pack of blades plus a tri-raiser with three blades and then you can order extra blades from our website as well. Okay, so now, what do we do with this triangle section in the back? Good question, it's getting...  I know, sometimes it's hard depending on where you live, South Africa, probably some unfortunate shipping charges in that. Here's the other thing though, if you're able to get the feather blades, blades that look like this, and we didn't invent the blades, so, but I mean, we obviously package them for ourselves but if you're able to get these blades, you'd only have that shipping charge one time. So it wouldn't be as bad, you just gotta pay for it once. But then you can get yourself a tri-raiser. All right, so what do we do with this triangle section in the crown? So you can either cut it with scissors now at this point, if you want to go a little more precise or if you wanted to kind of just carve into it what I'm gonna do, I'm gonna start bringing some of this hair over to me and just drawing these lines that I want. So kind of working through it, looking underneath, because remember I've got a guideline that kind of comes through. So I'm gonna bring the hair over and just start etching away at a line, creating a nice soft line for myself.  That's the beauty to me of a razor is being able to just kind of have this tool in my hand over-direct the hair where I think it needs to be and then just creating those softer lines within the haircut. Shoulda had a fidget spinner in the middle. You know what's funny? So thought about it, because obviously you spin it in your hand, but it just seemed to cheapen the look of the tool. So for me, still wanted it to look nice. Wanted it to be, you know, more classy looking. But I totally agree, Catherine, it would've been cool to have a fidget, a little more fidget spinner-ish look in there. So what is over-directing the hair one way and then over-directing it the other way and cutting it? What is that doing for me? It's pushing the weight into the center back of the cut. So longest point's gonna be here. I kind of want that for now so I can play around with it and decide how I want that to finish up. And again, so as I look at some of these little hairs, I can decide, this is a slight disconnect underneath here as we cut the underneath a little shorter. So definitely a cool little look for it. I'm just reading some of your comments. I'd love to experiment with the tri-raiser as shears could be a challenge to handle. Yeah, I mean, you gotta learn both, but I get what you're saying. The tri-raiser's such a cool, I think you need both. I mean, you definitely need both, 100% need both. I always trip. But just the freedom and the creativity of using a razor is for me just a really kind of fun to do. All right, so now we just gotta figure out what we wanna do with these top sections here. Look at that shape though, it's super cool. This is that kind of more lived-in disconnect in this back area. Really dig that and then these longer lengths throughout it. All right, so let's see, what do I wanna do here? Maybe I'll make like a convertible kind of top a little bit longer top to go on this. Like that might be cool. All right, let's do that. So back out a little bit. So what I'm gonna do is I'm gonna take this section here and I'm gonna pull it over here and cut it. And then that's going to release weight over this and then I'm gonna go cut it into it this way as well. I just feel like that for me is actually changing my mind. So I'm gonna let down these two sections. So one section here is the beauty of having a mind as you can change it. That's a T-shirt right there. It's a T-shirt saying. Anybody ever heard that saying before? Not sure. The beauty of having a mind is you can change it. Hmm, thought of the day. All right, so I comb these sections down. Jess says I think you should leave some of the bottom bits choppy. I agree. How do you see which side is which on the tri-raiser? So, I don't know if you mean which side takes out the certain amount of hair but on all sides it tells you there's writing. It says texture 25, texture 50 and then cutting 100, means 100% of the hair, 50% of the hair, 25% of the hair. I'm glad you love this look. Did that, Tiffany said that. Thanks Tiffany, I appreciate that because I wanted to get a little creative and just kind of create something in front of you guys today. So that's what we're doing. Having some fun. There's no thought besides inside my brain prior to this. Just wanted to get in there and create. So now, again, elevation up just a little bit. Here, I'm gonna bring this hair out. I've got my guide still from underneath and now the heavier back and forth motion you make with the razor, the lighter the line is gonna be. So I bring this hair out and I just continue cutting through it, creating a soft line. I'm gonna bring some of this hair back because I'm gonna start pushing some of that weight to the front and I'll cut into that more. Thanks Diana, appreciate that. Watching from Guayano, South Africa or South America, nice. Diana, I can't read, this is my first time. All right, thank you for joining. All right, so elevation is key. I'm just gonna work that short to long line throughout. Bring this hair back to me as well. Yeah, I'm really digging like that shaggier short hair falling over top, it's pretty fun. Now we've got our fringe area, drop that out. And this is where I wanna kind of cut more of a, not like I guess curtain type fringe so that it just lies right on the side here. So it kind of opens up the face a little bit. So curtain fringe, one of the easiest things to cut with a tri-raiser. So I'll show you guys how to do that. So I take this whole triangle section and I'm gonna do this bit by bit. Sometimes I'll hold it all in my hand, just cut it but I really want this to be a little more organic feeling. So I feel like almost every hair is important in this. So I'm gonna part this down the center and separate the two sides. And now I cut the other parts of the top, the other sections from the top. I cut those more triangular because I brought them back and pushed weight to the front.   So, and I'm gonna do that kind of piece by piece. So here, I start combing it down. See what it looks like flat because a little bit of wave in the hair can kind of lie to you a bit. Write this down a little bit, nice and saturated. Okay, now take a little diagonal parting. And what I'm gonna do is I wanna hold it kind of where it's going to fall. So when you cut with a scissor, a lot of times you have to over direct hair so that you get all these little hairs to go and cut it and then fall kind of short to long. When I cut with a razor, I can do that or I can just say, you know, it's gonna kind of fall right there and then just lightly start sketching in my line and where that hair is gonna sit. So I can say, all right, that's what I wanted to do. Then I take some more hair, add it in. And I kind of hold it down. I'm not holding it very light in my fingers, not a lot of tension. And just kind of draw and slide my hand as I go and I'll start to see that shape coming out. See my original guide? And then I'm gliding this over and hitting the surface of the hair but not cutting through it. Like if I cut through it, it makes a blunt line. If I softly flow over top of the hair, it softens that line and then it's gonna allow the hair to be a little bit more moldable throughout the haircut. That makes sense. Everybody, put your hand up if it makes sense. So now here's a little bit of pieces still left from that fringe area. This is where they're gonna live. So what I'll do is I'll just come in like this and I'll just softly draw out those little pieces. Whoa! All right, start kind of looking at what that shape's gonna do. Now I can start adding a little wave to it. See how the hair's reacting. Cut into some pieces a little bit more. Oh, that was blurry that whole time, huh? Sorry about that, guys. Okay, so now I do the same thing on the opposite side. I'll let this clip down. Take the tiniest bit out. And this honestly is, I'm gonna go the other side. I'm using the 100% side of the razor right now. I'm gonna use the 50 and the 25 and a little bit as I start working through this. But I wanna have 100% control right now, so softly just using that 100%, just not pushing it 100% down. Just lightly using it to cut on the surface here. It's not as much hair to cut on this side because she already kinda had a side fringe. And just a little surface gliding over. Okay, so now we've got our overall shape. Now this isn't, it's not done at all, but it's, you know, the wet part is done. Now we're gonna go in. I'm gonna blow it dry. And then I'm going to start detailing it dry, which is gonna be the best part. So don't go anywhere. Make sure you stay tuned. All right, so we're gonna use NeuroPrime, Paul Mitchell. See in our eyes, there you go. NeuroPrime, it's a blowout primer, thermal protector. So it's a great product for protecting your hair from heat damage, but also giving yourself a little bit of hold just to start off your style. So we got that. Now, once I get that product in the hair, I'm gonna use my Ergo Diamondhead brush. Ergo brushes, in my opinion, at this moment in time, because I can't predict the future. There we go. Or my favorite brushes on the planet. So the biggest thing about this brush and why I love this one so much is that it is a mini paddle brush. So you've got a regular paddle brush, which is this big, little focus, so it's this big. And then you've got your mini. I like paddle brush the most out of all brushes for blow drying, especially like prepping or quickly trying to dry hair but have control of it. But the mini paddle brush is so much better for short hair. So when I'm working through, I'm blow drying men's hair or shorter women's haircuts, bobs, things that I want that tension, I want that round brush tension, but I don't want the size of the brush. Then that's why I go in with this guy. So these are also available on our online store. I think they're like 38 bucks a piece. Great, great brushes. Great brushes, great brushes. Thanks, Lynn, appreciate it. My favorite brush, Rhonda's saying. Very cool, I love my Ergo paddle brush. Blanca, very cool. All right, so we're all on the same page. That's right, that's why we're a fam because we all know what we like. All right, I'm gonna do a little music today. I'm feeling music for a blow dry, what do you guys think? I don't have any new songs, but I can put a song up. Let's see, here we go. A little music, music for us all. Hope you guys enjoyed the little dance party there. We're gonna back into it now. So, blew it dry, tried it very hard not to disturb what it naturally kind of wanted to do, texture wise, haircut wise. You know, I think for me it's like I could really smooth this out, but then that's not the reality of the cut and I honestly didn't really want to take away too much of the volume either. So, and we're gonna go in guys. If you're just tuning in, this is not the haircut. This is the base of the haircut. Talked about it a little bit yesterday. I think with the virtual cutting club we were talking about cutting a bob wet and just basically that that's the foundation. I always kind of relate what's happening in my life to things that I teach in hair and just hair in general because I think about hair a lot, but so there's some work being done in my house right now like some different like hard escaping work or whatever but anyways, the important part of this whole story is that it has to, it looks worse before it looks better and you put in the foundation, you put in like the everything and you start, whoa, that doesn't, but if you trust your gut, your instinct and you understand what you're doing, then it's just part of the process. So you're just kind of going through and stamping in that foundation with a purpose and then going in and finalizing and decorating it, making it fit the person after you get it dry. So that's what we're gonna do today at this point. So right now I've got a super heavy top sitting on top of a very light shape, some disconnection, also some long, fringy pieces on the sides. So that we've got to kind of adjust. So, but the overall shape, the movement is exactly where I want it to be. So that's kind of the important part. Cut into that in a sec, see the rat shape. Totally moldy though, it's super cool, love it. All right, little coffee. Is this live video always this hour? Yes, for the most part, actually that's not true. This live video is I'm Live Every Tuesday at 12.30. Brian and Danielle are live every Wednesday, Thursday at 10 a.m. and then I'm also live on Mondays doing men's cutting at 12.30. So I'm live at 12.30, Monday, Tuesday, Brian and Danielle at 10 a.m. Wednesday, Thursday. Okay, DB 20, which is going to Stephie does hair so congrats, Stephie. You guys want to see how terrible my handwriting is? Stephie does hair right there. This scissor that I'm holding in my hand is going directly to them. I am, but I'm gonna do my last haircut with it. It's been a good five years. It's a $950 scissor, but all of you guys were so gracious to donate to the charity yesterday that it's going to a new home. All right, so now razor cutting. This is why I say that scissors and razors go so well together because sometimes you don't need a totally fringy haircut, right? So what I want to do is I can look at some of these lines, some of these longer pieces that I created and I can go in and now start softening this shape a little bit. So here we go, you can see that. Pull that down, now I'm gonna start cutting into it using Stephie's DV20. Some of you guys missed the drawing. We did the drawing right at the beginning, so we did it from a hat. I'm gonna do a drawing again because Jess has given up her tri-raiser and so we'll pick a different person for that because she already has one. You can see just a half close of the scissor sliding through. Stephie on here today, we've seen her. Her or him, I'm not sure. So a couple things I wanna show you guys. So I have a longer piece of hair that's part of this kind of fringe area. I don't need that long piece of hair. So it played its role kind of in what it was but I can hold it out like this and I can actually cut into it, just soften the way that it falls on the head there. On this side, do the same. Very similar thing, sliding, cutting. You could do this with the tri-raiser as well so you don't have to do it with a scissor. I just wanted to cut with this thing one last time. Make sure it works well for Steph there. Okay, so now let me cut into this fringe a little bit. I'm actually really digging this shape we have so far. And this out in front of me, cut into it. Yeah, same thing on the fringe here, just bring it out, point cut. All right, now goodbye my friend. I'm just kidding, that was super dramatic. All right, now tri-raiser. One last little kind of detail work that we're gonna start working through it. I'm also gonna use plumageal invisible wear, boomerang, restyling mist, just to mist it through the back. So, and what this is gonna do is just soften the cuticle just a tiny bit because I'm trying to create a nice soft, like a softer short haircut, not a mullet, right? So we kind of have a mullet now which some of you guys are probably like I love it and I'm the same way. But I can guarantee to you guys that the internet won't love it as much as we do. So I'm gonna go right here. I'm gonna take my Texture 50 side of the tri-raiser and the reason I like to use this, I love using this on dry hair because there's more blade exposed. So when you have more blade exposed, I can literally like use it almost like I'm using it as a dry cutting scissor, right? So I can go through here, I could pinch and cut and remove a ton of weight. I can pull the hair in my hands like this and cut but you can decide. You know, if you wanna use 100%, that's fine too. It's just turn the razor, have some fun with it. What I'll do is sometimes go in 100% through it, get that length off, then go in Texture 25 and then right where this divots in a little bit, I'll go in Texture 25 and just kinda slide through it and that'll help skinny up this little bit of the hair as well. Surface, same thing over here. Now, getting close. Lying through there, skinnying up these two corners. And now, my favorite thing to do. So these are my, I use three tools almost every haircut. I use a tri-raiser, I use a texturizing scissor and I use a blunt or wet cutting scissor. So now, I wanna soften some more. Underneath here is so perfect, like this is what we did with that one swipe of the tri-raiser, you can see right there. I'll just lay this nice. It's got a little bit of movement and then this disconnection falls over top. So what do we do with that disconnect? It's really kinda fun to go through and cut this disconnect in half. Comb just a tiny bit over, see what it looks like. I'll put my Velcro clip up there, hold that in place and then I'll just take my texturizing scissor and I'll start working some of that hair that falls over. I'll just start working through that, just sliding it. Comb the hair back the way that I want it to fall, the way that I want it to kind of flow back and then I'll cut a little bit more, just kind of making it lighter through that disconnect into the back, which then takes on a shape that I wanna skinny up into a little bit more here. So I'll go in, you see how we start cutting into that and how it just skinnies it up, that's the goal there and I'll continue working on this side to now let out my Velcro, it'll pop over. Now I wanna keep length on this disconnect. I don't really wanna go too short, but the lighter you get with it, the easier and the more like you could just throw in a tiny bit of product and kind of style through it. Here, I'm in, I'm gonna do the same thing on the opposite side, so over here. So see the difference between that and what that looks like now? The big difference looks a lot fuller, thicker over here. Lynn asked if I were to choose one texturizing scissor, what would it be? It would be this one, the Yoragi number six from Mizetani. Sell it on our online store, it's my go-to number one scissor, texturizing scissor that I ever use, it's my favorite. The only other one that I like about the same, but I love, I do like having a blade on there, but if I'm trying to go through longer hair and glide through it, then sometimes I go with this Mizetani Type Z dual texture, which basically is just a texture scissor with two texture sides. So when you cut, you can see that there's a gap in between, when you cut with a regular texturizer, there's a slight gap, but you can see a blade in between all the teeth, sometimes that blade, you don't really feel it because these are so sharp, but sometimes a blade in your texturizing scissor can get a little caught up in the hair. So this, just a really awesome scissor, they both are, they're both awesome. And this one's about $200, I think, cheaper than the dual texture, so probably another reason why I just like it. All right, so now, go across that Pridal Ridge area, let some of this hair fall, comb the rest over, and I'll put my Velcro clip in here, right along the parting, and then I'll start combing this hair back and get ready to work through it. So, just like the other side, go in, and then this is another cool little feature of this scissor. So I like to always have the blade kind of following in the hair and then the other texture blade comes down and cuts it. So, on the other side, I would go this way, right, and cut, but when I come over here, now this texture side's down at the hair, so all I have to do is flip it because there's a tang on both, on both, so I can just go in and I still have my blade first. I'll just go in there and work through it a little bit more, and I'm really just trying to grab the surface of this, I'm not trying to cut too far in to the hair, so I'm not over cutting it. And the one thing about cutting with a razor is that all this work that I'm doing, I would have to kind of do double that work because if I used a scissor to cut it because the lines would be so blunt and it would be so thick that it wouldn't fall soft to begin with, so it's just something to think about as you're doing this haircut. Lift this hair up. I'm just gonna go in with my texturizing scissor here and just point cut through, just removing some of this and then take the ends out, and that's really just to kind of connect the top and bottom. Now the last little bit, we gotta go into the center, remove some of that weight, and then honestly, I can just like start really piecing through using this texture scissor and decide how long do I really want that hair to be. I'm just gonna take it a tiny bit shorter in there, almost there, almost there. All right, all right, cool. So we're almost there. Nice bit of palmitial spray wax. Yeah, Brian could give her a cool color now. True that. I wanna leave it like, I don't even really wanna mess with this fringe too much because I like that it's just kind of bouncy and not fully interfaced so the internet won't freak out too much. Oh yeah, oh yeah. Oh, I'm definitely digging this haircut. Hope you guys are too. Finalize it with this DB20 here. So what do you guys think? Pretty cool, I'm digging it. Hope you guys like it as much as I do. Hope you guys had fun today with me. Let's do a drawing again for Jess's tri-raiser that we're giving away here. Let's see. If it picks Jess again, then we know it's just meant to be. Otherwise, we'll see. Let me go here. All right, glad you guys like it. Is this live on Minerva today too? Yes, this is live on Minerva as well. The only thing it's not live on is my Facebook so I want a lot of you guys to understand that a lot of the internet is kind of a game of like what Facebook wants you to do.  So it's showing it to way less people so I'm trying to recover a little bit so I'm live on Freestyle on Education, Minerva, and YouTube right now. All those Facebooks and YouTube channel. All right, here is our hat full of names. This is for the tri-raiser. Let's see, and the winner is, that one jumped out. That's meant to be. That's serendipity, that's serendipity. Loving life 2474. Loving life 2474, beautiful. All right, what happened to Jess's tri-raiser? Jess gave hers up because she already has one so she wanted everybody, she wanted somebody else to have it which is a very, very nice thing to do. All right, guys, so do we have any questions? If you do, type Q, put in your question. I'll be on here for a couple more seconds. Shout out to them for their massive donation yesterday, for sure, yeah, I'm happy. I think they donated a lot. I don't even know the specific amount but they donated quite a bit, especially for like an individual donation but it's not about, I mean it is about the amount of money that you donate but the fact that any of you took any of your money and donated it to the charity to really help my son hit his goal of $6,000 is incredible and me and Christina and Hayden cannot thank you guys enough for that. Very, very appreciative of you guys stepping up and doing things with us and having our backs which is kind of what it's all about so I appreciate that, all of you guys. Let me go here, Jess Mac, was it $500? Yeah, could have been, 500 bucks. Incredible. Or maybe you're talking about Minerva, I'm not sure but Minerva stepped up, donated $500, Millennium Systems International, so those two companies if you guys are looking for salon furniture or you're looking for salon software, you either got Minerva Beauty for salon furniture and equipment or you've got Millennium Systems International for salon software, that's the software that we use, they do not sponsor any of our stuff right at this moment but they always seem to jump in for my son every year and I can't think them enough for that, John Harms is an awesome guy. So if you guys need software, salon software, Mevo too is what we use, so go check that out. Yeah, Jess's talking about Minerva, okay. Cause living life, 2474 I think is the name, donated like a couple hundred bucks too I think or something, over a hundred I know that. Let's see, when you don't have a double tang how would you adjust with the texturizing scissor? I think you just have to, that's a great question. So Yana, so you could, so if I can't adjust like let's say I'm here, then I would just go like this, come back and I could do that and then when I got over to this side I could just go through that. So you can always find your way cause you can always have that part of the scissor down. It's just easier if I can go like this on one side and then flip it when I get to this side and flip it around and do the same exact motion. So it's not that big of a deal, like you don't have to do it but it's for me I just like it. Let's see, all right cool, I think we're all good. Again, thank you guys, you're the best. Can't wait to see you guys live tomorrow, 10 a.m. Brian's gonna be doing a toning class. We're gonna talk about different toners and the way that they react to the hair it's gonna be really fun. So we got an hour with Brian tomorrow, 10 a.m. to 11 a.m. and then Danielle's gonna be doing some up styling for Thursday. So a lot of cool things coming up, things that I don't teach that I'm so happy that they're here with you guys teaching that stuff. If you guys need anything, go to FSE now, download our app, easy to send a message to on that and then also make sure you download the app. That would be great. And if you need any tools or anything, go to shopfse.com which is our online store and you can purchase the Velcro clips, the clips, the scissors, the combs, the tri-raiser, the brushes, everything that I pretty much used to create this look you can get on our online store. All right. Yeah, and the shears are Mizetani and the website is FSE as in Free Salon Education. So FSE or shopfse.com, shopfse.com. Or just go to freesaloneducation.com, click on shop, it'll take you to it. Or if you're on our app, click the shopping bag at the bottom of the app and you can go to the online store that way as well. All right, cool guys. Thank you. Hope you enjoyed the look. Hope you enjoyed the class. Can't wait to hang with you guys again. I'll see you guys on the next class. Thanks.


OK, we're at 10.2, so I'm going to kick off. Thank you everyone for coming. This is a bigger crowd that I'm used to dealing with, so this should be interesting. My name's Stephen Finwchern, I'm a software developer working for Red Hat. I primarily focus on NFE, SDNE kind of stuff. So anything to do with CPU pinning and new movie stuff, that's my kind of problem to me. Today I'm going to be talking about a new feature that's been introduced in Nova in the last cycle, the Rocky cycle, called Numerware V-switches. And because of the attendance of the crowd that's here, I'm also going to focus on some kind of similar features in the same area that I think people should be aware of. I'm coming from a development perspective or background, but this talk is mostly focused towards the actual deployment and usage side of things. I won't go into too much detail about how any of these things actually work under the hood, but I'll leave time at the end for questions. And if anyone wants to catch me afterwards, you can do so. I'm happy to answer any questions you may have.  Again, very high level, there's no point, I won't go into too much detail about it. Just so you can understand the kind of problems it can cause for deployments and why we need to come up with solutions like Numerware V-switches to work around them. I'm going to go through the actual Numerware V-switches problem itself and a couple of the approaches we tried before finally talking about the actual solution that we settled on. After that, I'm going to go through some common questions that people have asked me on this over the last couple of months. And then that bonus section, I'm going to cover some related features that I think people should care about and then wrap up in questions. So starting from the top, what is Numer? So it stands for non-uniform memory architecture and it's a computer process of architecture that's seen common adoption on platforms in the last day period or two. Pretty much if you have a modern server with multiple CPU, multiple physical packages, you're going to be dealing with Numer unless you've explicitly disabled it. From a graphical perspective, this is essentially what looks like you have at least two nodes and processes running on one node, be it a physical stacker or a die within two or within the same package. Memory access is from that to memory associated with that node as fast as you'd expect. If they want to access memory associated with another node then you incur performance penalty. And that performance penalty can vary but 50% can be quite common for something like this fee switcher's issue. If you're talking about multiple circuits, this has changed with Intel processors over the last year. It's more of a mesh topology now but jumping between different Numer nodes, it can have an increasingly negative effect on your performance. So naturally what you want to do for almost any process where on a platform where Numer is enabled is you want to make sure that memory accesses where possible are local to the nodes so you're not having to jump across these links. And this doesn't just affect your processes, it also affects anything on your host that consumes memory. So that includes PCI devices, so things like NICs because they have this same issue. If you have a PCI NIC and it will be associated with a given Numer node and if you have processes running on different Numer nodes you're going to get those performance hits. So when we talk about the kind of networking that's available, there's three, there's a load more because networking is weird and special. But the three that most people spend their time talking about would be the kernel of Vhost or legacy.io, user space Vhost which is generally typified by things like DPDK V-switch and then SROV. So each of these comes with their own pros and cons. I've listed kind of flexibility versus performance but there's a lot more that has to be taken into consideration including cost and things like this. The main comparison, the most useful comparison here is between user space Vhost and SROV because these would be the most likely ones you'd see in a deployment, NSDN, NFE-based deployment. So if we have a look at this diagram to VNFs you've got two physical networks and then you're going to have traffic going between the VNFs and the physical networks plus some management stuff which we're going to forget about. Because we have this Numer topology thing that we need to be concerned about that previous diagram ends up looking something more like this. So unless you've specifically said otherwise, each VNF and instance is going to be running on, is going to be isolated to a single host Numer node. And what you don't want happening is you don't want your VNF running on a different Numer node to where your NIC is, where all the traffic is ingressing and egressing from the host. Naturally you want to co-locate those stuff on the same Numer node. For something like SROV this is pretty easy to do because NOVA since it added support for SROV and PCI Passu has taken Numer topologies into account. There's actually an uncomfortably tight coupling between Numer and things like CPU pinning which I'm going to talk about later. We're trying to separate that going forward but if you boot an instance with SROV interfaces you will get Numer affinity. It won't let you boot that instance unless you can get that Numer affinity. But that's not the case for something like OVS because NOVA doesn't have that view into what NICs your chosen V-switch platform is actually using. And obviously I'm going to go into this now but we don't want to go and have to teach NOVA how to do all of this stuff because NOVA cares about compute, it doesn't care so much about networking. So how we attacked this problem and came up with a solution. The solution that we landed on obviously wasn't what we arrived at day one. This was built up iteratively by looking at various different choices that we had. Starting off we're talking about V-switches. NOVA doesn't need to know about networking therefore the simple answer would have been well we can let Neutron do all of this for us. The issue with this is that you need to think about what NOVA is aware of and what Neutron is aware of. So NOVA knows things about compute resources so basically what kind of basic resources you have available to you. Whether you're using Livevert or QMU, just walk QMU, that kind of thing. It also knows things like pneumatology because it has that introspection through the Livevert API or the Zen API API and so forth. And Neutron doesn't know any of this stuff and just as we don't want NOVA to start learning how to inspect OVS, we don't want to have to teach Neutron how to inspect Livevert and Zen and Hyper-V and whatever your chosen hypervisor is. Placement seems like the saviour for pretty much every problem that opens back at least in the NOVA and Cyborg and Neutronsphere. The saviour for pretty much every problem we have. The problem with placement was at the time that we were working on this and even now the features that we needed placement didn't support them. So we could have waited three or four cycles for these features to land in placement, but even then this placement has been in development for quite a long time and 50% of performance here is quite a substantial performance here. And we at Red Hat were trying to support these custom hacky workarounds that involved restarting services and stuff and we didn't want to do that. So essentially placement wasn't a viable solution for us at the time. NOVA, again this comparison of what NOVA knows and Neutron knows. The biggest issue is that NOVA doesn't know how to inspect and pull out information from OVS and therefore and we didn't want to teach it this stuff. But we thought about this for a little bit longer and we realised that actually there wasn't any real reason to go and do this introspection. We were able to work around this. So we assessed those on NOVA as the solution but with some caveats which I'm going to explore now. So when you're trying to categorise Neutron networks there's two primary ways that they, if you go through the Neutron documentation that you'll see them categorise. The first is something like provider and tenant networks. There's a load of other stuff, I found it quite interesting when I was working on this that I was talking to Neutron cores and asking them questions and before long I started getting back we don't know as an answer which was quite interesting. So provider networks versus tenant networks is a very kind of neutrony thing. There's more to do with who's doing the configuration of networks and what the underlying topology is. It meshes a load of stuff together but it didn't really apply to this. Pre-grading networking and self-servicing networking again didn't quite map up to what we wanted. What we actually wanted to know was whether a network was an L2 network, used something like a FISnet or whether it was an L3 network. And the reason for that is because whether it's an L2 network or whether it's an L3 network determines how many nicks your network is allowed to use and how they're configured and accessed. So if we look at the sample configuration this is from one of the configuration files for Neutron. If you're using the ML2 OVS plugin this configuration option maps an OVS bridge which I guess you consider like your primitive to a Neutron FISnet tag. So it says if you have traffic going through this FISnet this is where it should get tunneled in and out of. From the Nova side of things we introduced a new configuration option and dynamic groups and what the configuration option let you do is you said what FISnets were available or accessible on your host. And then a plain old this is what NUma nodes that this FISnet maps to this is what NUma node this FISnet maps to and so forth. The advantage of this approach is we didn't need to teach Nova how to do that Neutron inspection. I didn't need to learn how to go and use the OVS DB APIs and import a load of code from Neutron or redevelop code. And any deployment tool worth its soul is that's doing configuration of these networks anyway. So that already knows all this information about what nicks you have on your host and is able to introspect and find out like what the NUma node is and stuff. So this moves it from something that has to happen at runtime to something that you can configure as part of your deployment tooling. An interesting point that came up during this is in real productions most people tend to use nick bonding to make sure that they have like active passive failover and fancy networking stuff. So we made sure that this NUma nodes configuration option was able to be a list. So if you had multiple nicks connected and for some reason you decided you wanted to place them on different NUma nodes for whatever, you would be able to do that without, you would be able to do that without this option you wouldn't be able to do that. L3 networks are a little bit different so where with L2 networks you can then be typified with having multiple fizznet on a host. L3 networks, they all have to go through the same endpoint so you configure your endpoint IP. You can use multiple actual interfaces but they'll have to be bonded together. So that made the configuration, again this is an example from the ML2 OVS plug-in. That meant the configuration from a nova perspective is actually a lot simpler for the tunnel side of things. And again we were aware that people do bonding and they can also spread this over multiple NUma nodes so we made this a list. And that's pretty much NUmaWare vSwitch, it's not overly complicated and like in tests that we've seen without this feature, like I said up to 50% of a performance hit was possible in the situation where you had that diagram with it being in where a workload was running on one NUma node and your nick was located on a different NUma node so everything was going across that bus. This eliminates that basically as an issue, as a realistic issue. From the deployment side of things, I know that the version of triple O or the OSP deployment tool that supports this configuration manually in OSP 14 and the plan is to make sure that the deployment tool will just do it for you without need to worry about it in OSP 15 and 16 and so forth. So a couple of the common questions that I've been asked about this is A, why is it so manual? It is a pretty low tech solution given the solutions that had been proposed. The reason for that is going back deployment tooling knows all this information already. We didn't feel that there was a need to introduce a whole load of additional complexity into either nova or neutron and teach those systems about things that they previously didn't know about. Placements, you can automate all of this, we're exploring doing that in triple O going forward. And placement was explored and it was looked at in great detail. We made the determination that it wasn't quite ready for this but going forward we will probably be exploring moving this to placement. I would recommend there's a really interesting talk happening later this week. It's a demo for the bandwidth that we're scheduling. All of that uses placement and if anyone here, especially the more technical focus people, is interested in this stuff I would highly recommend going to that. So outside of Numerware V switches there's been a couple of other changes that have happened in recent cycles. All focus on improving the performance or the determinism of instances with an NFV focus. The first of these is a thing called configurable TXRXQ sizes. In short, if you have an instance running and something on the host or within the instance preempts your standard workload and you have traffic flooding into that instance, that stop where it gets preempted and work happens on something else before it returns to your main workload. You have queues and those queues can fill up pretty damn fast, which results in drop packets. From talk into architects drop packets seems to be like the worst thing that could ever happen. The solution to this is simply to make queues bigger. In all the testing that Red Hat have done and various other companies have done on pingfarm the default, which was 256 up to 1024, was seen as sufficient to get the performance that they were demanding. But this is configurable because we're expecting people like we've moved from 10 gig to 40 gig and 100 gig is already I guess in production and who knows where it's going to go after that. This is available in Rocky and a sample configuration is provided there. Another one, this is more useful for people that be thinking about real time workloads. So if you are running an emulator, the emulator, a hypervisor, the hypervisor itself has to do a certain amount of work, whether that's basic IO or just kind of like clean up tests. These can steal resources from CPUs and if your CPUs, your VCPUs are running real time workloads, you don't want anything else stumping on them. So the solution to this, the initial solution at least, was to assign a dedicated core for each instance that all this overhead stuff could get thrown onto and keep it away from your main workload cause. This was introduced in the Cata, but in Rocky we've built upon this so that instead of having a single core per instance, you have a pool of cores and all your workload is all those overhead tests are all pooled on this pool of cores. Sample of how you configure the former and a sample of how you configure the latter from the command line. And for the latter there's also some NOVA configuration necessary. And then the last one which is, this is still under development at the moment. I said earlier on that we have this unfortunate thing in NOVA where NUMA and things like CPU pinning have been really closely coupled for not very good reasons. We are moving things like bandwidth that we are scheduling. That's all happening in placement. We've moved VCPUs, memory, disk, all of that stuff into placement. The next step in this from the NFE perspective is to start tracking PCPUs as well as VCPUs. So that we're expecting this work to be completed in Stein and from the user side of things. This will have two implications. The first is that the days of having to split your cloud into hosts that will run dedicated instances with pin CPUs and hosts that will run non-dedicated instances, normal shared floating CPUs. That won't have to happen anymore because they'll be able to coexist on the same host. The other thing is that you'll be able to mix those pinned cores with the non-pinned cores within the same instance. So you'll be able to say, well, I've got eight cores in my host. I want six of them to be pinned and then I want two that are just going to be doing internal OS overhead stuff that don't need to be pinned. They can float. We're going to do all of this through tracking it as placement. It's not completed yet, but this is roughly what it's going to look like. Anyone that's worked with placement before should recognise these kinds of commands. This will all be exposed via Nova Comfort configuration. The last one, this is the personal bane of my life because of the amount of times I've had to support issues around this. Live migration for instances with a new metapology or CPU pinning at the moment is completely and utterly broken and it has been broken since it was implemented. There's some workarounds that people will do. More experienced operators will have their own little bag of tricks that they'll use, but the fact remains that it doesn't work out of the box and it should. The solution to this is to fix it. The technical details of how we're going to go about fixing that would take a session by themselves, but this is in the pipeline for this cycle. So quickly recap what I've covered today before I move on to Q&A. Firstly, not accounting for NUMA can have tremendously bad impacts on your performance and therefore you should account for it. NUMA-aware V-switches have been introduced in Rocky. This closes one of the issues that we're remaining open issues we had around NUMA and NUMA awareness. This is based on a Nova configuration config and we think of it as mostly a deployment issue, future versions of triple O and I guess other deployment tools will make this configuration almost automatic. We will be looking at moving this into placements in the long term, but I envision that being three or four cycles, so that'll be about two years down the road before we're in a situation to do that until then this is the way to go about doing that. There are a whole load of other features that have been released in the last cycle or two that I would highly recommend anyone working in this area focus on and look into. With that, that is a 10,000 feet view of NUMA-aware V-switches. If anyone has any questions, feel free now or after the talk and thanks for listening. As you mentioned that some of the features landed in Rocky and some landed in Akata is OISP director upgrade takes care when you upgrade from the earlier version to the versions that do support the configuration automatically or that needs to be done manually and wants it integrated with Rocky from that point on is upgrade both one version upgrade as well as fast forward upgrade handles. So my understanding of this is it depends on the feature you're talking about. So triple O will handle migration of, so if you have a feature that existed in one release and it changed in another release, then it'll handle the migration between the two of those. But in terms of when you're adding additional features it doesn't tend to tweak any nubs around that. Specifically the NUMA configuration which you were introduced. Yeah, no, it wouldn't turn that stuff on by default. That would be, I'm not sure how you'd actually go about doing that but it would be an operator would need to supply input to say this is something that needs to be switched on now. We wouldn't do it by default in case we broke something, somebody didn't want it. Any other questions? If not I can run away. Thank you very much for listening and enjoy the rest of your summer.


Hello, and welcome to episode 11 of The Daily Decrypt. I'm your host Amanda. Today, Bitcoin is $264, Dash is $2.33, BitShares is 40% of a penny, and Monero is $0.39. So firstly, I wanted to tell you about this site that launched over the weekend called I'm not even sure how to pronounce it, Sato, it's S-A-T-O, but then it's Dot-S-H, so it's like Satoshi, like Satoshi, but it aims to be a content sharing site that pays users to post content that ends up getting upvoted, and naturally users are paid in Bitcoin. It looks like it's in its alpha testing phase right now, that's what the email I got from them said, I must have signed up to be an alpha tester, I forgot, or maybe I remember a little, but yeah, it looks like I can send invites to other people, so if Satoshi, I'm just going to call it Satoshi, sorry if it's really saddo, if Satoshi looks like something that you would be interested in using, tweet me, or just leave a comment below the video and I will send you an invite, give me your email naturally. Next, Mashable is reporting on this device that's called, I don't know if it's pronounced the NINABOT or the NINABOT, either way it's like a Segway, but it's cheaper and lighter weight, and instead of rising up above, you know, up to your hand level, you just balance it between your knees, and apparently it's only like $320 or something and is already for sale in China. When I first saw it, I thought it looked kind of silly, I mean like Segways never took off, right?  Another weekend discovery of mine was this site called Crypto Grind, and Crypto Grind is like the fiverr for people who want to buy and sell in Bitcoin. Now I hear you already saying, but fiverr accepts Bitcoin, well yes they do, but they do not pay out in Bitcoin. In fact, I even had a rude experience with their customer service people recently, when I emailed them asking when they planned to offer freelancers a payout option in Bitcoin, since people can pay in Bitcoin, and I received a boilerplate response just directing me to their frequently asked questions page, which I had already read thoroughly, so for freelancers who would like to get paid in Bitcoin, it looks like Crypto Grind might be a good place to start, and the site launched about a month ago, so you would likely be one of the early and few users. In very cool health news from Gizmag, there is a postgraduate student named Divesh Mistri, who attends, mystery, that's a cool last name, who attends the University of Leeds, and he is working on something that he believes should be able to replace the need for reading glasses as people age. He says as people age and their eyes begin to stiffen, that's when they become long-sided, he calls it age-related long-sidedness, and so he is working on something which uses the liquid crystal that's used in the screens of televisions and smartphones to develop a surgical implant that would auto-adjust as your aging eyes change in needs over the years. Mistri says he would like to have a working prototype of his eye implant by the time he finishes his doctorate in 2018. Hurry along, Mistri, hurry along, the world is waiting for your invention. Syscoin, S-Y-S. Syscoin is among the more recent contenders in the decentralized marketplace software, if that's what you want to call it, among contenders like Open Bizarre, Bit Markets, NXT Free Market, these sort of things, and they are looking for beta testers currently, so if you are interested in helping to bring forth whatever the real peer-to-peer decentralized marketplace that really takes off happens to be, go ahead and check out this reddit post and get signed up to test. Gizmag also reports that the European Space Agency has announced that it has launched a CubeSat, which is short for CubeSatellite, small, into space to track aircraft as it flies through the air, and then this just got me thinking because I had heard before that CubeSats were affordable for, you don't have to be like some government agency to have the budget to actually be able to use one of these things. Apparently you can buy a kit from a site called cubesatkit.com and for $50,000 or less, I don't know what all of the exact quotes are, you can custom-build an actual satellite and purposes for why you might want to launch one range from atmospheric and biological research to radio communications to simply taking photos in outer space. The devices last for up to a few weeks or months in space before they then head back into Earth's atmosphere and burn up in the process. Now this story I wanted to say for last because it is a big mind trip for me. Bitcoin.com reported on a site called Time Republic and on Time Republic people buy and sell services from one another but rather than doing it for money they do it for credit hours like labored hours and so you can earn hours by performing a service for someone or send others earned hours when they perform a service for you. So I saw a video sometime last year and I wish I could remember which video it was and who was talking in it but it kind of it changed an assumption that I had held and that assumption was that barter used to be a thing before money arose, you know money in the form of salt or shells or stones or whatever. I have read and heard more things since then that say that barter never actually could have been a thing it would have been so inefficient that it's more likely that primitive societies would have used what's called the gift economy which is basically keeping mental record of who you owe and when you owe people and when people owe you and so it's really just more like calling in favors or performing favors and so Time Republic has my gears all turning here because it is a moneyless economy that almost functions like that like like the primitive gift economy but obviously not primitive because it's taking place you know among participants on a global level digitally. So I'm gonna leave it at that I'm gonna probably go stew over what it is Time Republic is doing for the next 24 hours and maybe I'll get back to you on that but that is that is a marketplace I also wanted to share with you and maybe you could buy and sell there too as well as crypto grind so many opportunities and lastly this Bitcoin powered Mortal Combat arcade game was spotted at a cafe in Prague called Parallel me police and that's my friends has been your daily decrypt thank you truck follow us on Twitter why don't you you can find us at the daily decrypt

Hello, I'm David Patal, I'm a researcher in the climate change group at IIED. My work focuses on climate resilience and local governance, particularly in the drylands of East Africa and especially Kenya and Tanzania. A lot of what I do involves developing and assessing participatory planning tools. That's activities that allow communities to participate meaningfully in local planning processes. I've worked on toolkits to bring out the specific climate resilience needs of women and youth, but I'm also interested in digital participatory mapping. That's a technique that allows local people to map out their land use patterns and explain them to government. Today's presentation is called Poor Governances Worse Than Drought, and we will discuss issues around water development in the drylands. Thank you for listening and we look forward to the discussion afterwards. Despite billions of dollars of investment in water development over multiple decades, access to clean and reliable water remains a mirage for millions of people, particularly in LDCs. It's been estimated that in 2017, 54.7% of people in rural areas of sub-Saharan Africa lacked access to even a basic drinking source. This is a really shocking failure to meet the aspirations of sustainable development goal number six. It's particularly acute during the COVID pandemic when access to soap and water for hand washing is critical to avoid the spread of disease. There is, however, another failing that's less visible and not sufficiently appreciated, that of failing to pay careful attention to the political and power dynamics that surround water development. Ignoring these can undermine local people's livelihood systems, degrade the environment, trigger social tensions and exacerbate poverty. Today's talk will explore how water development interventions intersect with wider complex power dynamics at multiple scales. It will present three case studies of water development in dryland environments in northern Kenya, where the main livelihood system is pastoralism. Now in these areas, the government and development agencies have broadly agreed that water scarcity is the major issue for development. They've also concluded that the solution is to build a lot of water points throughout the territory. Today's talk shows how taking power into account unsettles those simplistic assumptions. The first case study will show how water development has often been used to exercise power over communities. The second shows a more positive view, how water development can involve power with and power between local communities, helping them meet their priorities. Lastly, the third example shows how water development can address issues of unequal power within communities. The talk will conclude with some principles for using water infrastructure planning and governance that explicitly embrace power and show how water governance can serve as an entry point for multiple objectives, addressing marginalization, sustainable livelihoods, gender and social equity, and building climate resilience. To really understand the political and power dimensions of water development in dryland pastoralist areas, one needs to appreciate the pivotal role of water in pastoralist livelihood systems. In fact, water is key to the sustainable use of variable and dispersed resources in the environment. In northern Kenya, there are distinct rainy seasons when fresh nutritious pastures grow and when surface water is temporarily available. You can see that on the left here on the slide. These are followed by dry seasons when the pastures gradually dry up and lose their nutritional value. Surface water disappears and people in livestock rely on underground water, sometimes having to dig deep into the riverbeds of seasonal water courses. Pastoralists in northern Kenya have developed a system of communal management for making the most of this changing availability of resources across the environment. They collectively agree to set aside some areas for grazing their animals in the wet season when surface water is abundant. Other areas are set aside only for dry season grazing or as drought reserves. These are only to be used at times of intense climate stress. Here the grass is left to grow during the rainy season, creating a stock of fodder which is saved for livestock in the driest periods or during droughts. But they've got to be careful to protect these areas to make sure that no grazing takes place in the wet season and these areas can be extensive and very difficult to police. Control of water is the linchpin of this whole system because animals need both water and pasture to survive. Grass without nearby water is useless. So if you can ration or control water near a protected dry season grazing area, you can completely prevent grazing out of season and you can control the number of animals consuming the resource. In practice, what this means is that pastoralists generally have a few strategically placed water points in their dry season grazing areas and drought reserves. These points are carefully managed by local institutions that regulate access as a function of the availability of the surrounding pasture. These institutions also keep the peace with other nearby pastoralist groups that may want to make use of the pasture. But as the case studies will show, unequal power dynamics in the development of water infrastructure can easily disrupt or undermine these traditional land use systems leading to reduced livestock productivity, environmental degradation and social conflict. Our first case study is from Wajir, a vast arid county in the northeast of Kenya bordering Ethiopia and Somalia. It's a nomadic pastoralist economy with cattle, camels, goats, sheep and donkeys. This case study highlights how water infrastructure development can be an expression of power over a community. It shows what happens when water development is based on top-down interventions which are informed by negative policy narratives. These policy narratives that perhaps perceive pastoralism to be inefficient, backwards, and a cause of environmental degradation. In the late 1960s in Wajir, a livestock development project funded by USAID and CEDA tried to end traditional land use systems of wet and dry season grazing. They wanted to introduce the ranching model of livestock production instead of mobile pastoralism. They tried to partition the range lands into standard grazing blocks. Now water development was an integral part of this project of wholesale transformation. Four holes were drilled to provide water for each of the new grazing blocks created. The whole system was regulated by project technicians who would limit livestock numbers with regular offtake and destocking. By the mid-1990s, the ranching schemes had failed and they had been abandoned. The drivers of water development then changed. The location of water infrastructure was determined by the ambitions of politicians from outside the county working together with local clan-based elites. There were clear electoral benefits in establishing new settlements to concentrate votes and many new water points were built to serve these new settlements. They were built regardless of local existing patterns of land use. It was political manipulation that drove the siting of water. So what are the consequences of this type of top-down or politically motivated water development, this power over local pastoralists? What's been happening in Wajir is that too much water is being supplied in the wrong places. It's being supplied without concern for the delicate ecological balance between water and grazing. That means that the distinction between wet season, dry season and drought reserve areas has largely broken down over the decades. The map on this slide shows the location of the most important water points in Wajir in 2019. It's taken from a recent project undertaken by IIED in collaboration with the county of Wajir. The blue lozenges indicate the location of boreholes and the bigger the lozage, the more water the borehole can dispense. These can be particularly disruptive for traditional land use systems. More water means more animals will use the surrounding pastures, and many of the boreholes will be operational throughout the year. Then there's the sheer number of water points. Back in the 1940s, there were only four water points located in dry season grazing reserves, which is almost certainly too few. But by the early 2000s, with various rounds of water investments, this had increased to well over 75. And this enthusiasm for spending on new water points continues to this day. Between 2013 and 2018, the number of boreholes in Wajir rose from 98 to 272. As a result of unplanned water provision, the rangeland hardly gets any periods to recover, resulting in overgrazing, degradation and loss of valuable biodiversity. This decreases the productivity of pastures livelihoods and increases climate vulnerability. So what if we do water development differently? What if we use water development as power with communities, allowing local people at the village level to decide their own priorities? Our next case study comes from the nearby Kenyon County of Visiollo. From one of IED's key initiatives in the drylands, the County Climate Change Fund, or CCCF. The approach involves setting up and building the capacity of climate change committees elected by villages. The committee members work with their own communities to choose, plan and implement climate change investments that meet local priorities and needs. They work to known budgets and receive comprehensive training that allows them to act as real partners with local government in the formal planning system. So the community is in the saddle and it's thinking about development and resilience. What do they decide to prioritize knowing they have a limited budget? Unsurprisingly, water is a key priority, but among the various investments in the first wave of CCCF investments, one stands out. Take a look at this land use map of Visiollo. Notice the areas in green and in pink. Greener areas set aside for dry season grazing, and pink, their critical reserves set aside for periods of drought. The grey bits are not controlled so carefully, but mostly used in the wet season. Where you see the star, that's the Yamiche water pan. It was built by an external development agency several decades ago, but it was built without consulting the local community. Now, when the local community was given a budget and asked to decide on climate change investments, what do you think they decided to do? They asked to fill in the water pan, to close it, to stop up the supply of water. And the rationale was critical. The Yamiche water pan, they said, was in the wrong place and was not under their control. It's bang in the middle of an emergency drought reserve, a place where no grazing should be permitted during normal times. The Yamiche water pan was making the area open access, like leaving an open door to a storeroom. It was also causing conflict with neighbouring Somali pastoralists who were hopping across the border, helping themselves to the drought pasture whenever they wanted, and you can see that with the green arrow. So the community wanted the Yamiche water pan closed. At the same time, they wanted a nearby borehole rehabilitated. The borehole was a water source they could control. They could close it completely and deny access to the area until an extreme dry season or drought event occurred. That's a clear demonstration of how control over water confers power in the drylands and how it's the key to sustainable range land management. How about the Somalis who were coming over the border? They lost out by losing the water pan. But in the drylands, neighbouring communities usually have traditions of negotiable and reciprocal rights of access to water in times of distress. So the Somali elders could formally request access to the Yamiche borehole at times of distress, and most likely this would be granted, but in a controlled fashion, so that it would be a managed commons, not a free-for-all. Planned access would reduce the potential for conflict, and that's an example of water developed as power between communities. So we have seen the positive benefits of empowering local people to take the lead in planning water resources. For a third and final case study, we return to Wajir County and explore how water governance and planning needs to consider power within the community too. Although pastoralist customer institutions are great for sustainable range land management, it is elder men who dominate them, and their primary focus is the well-being of the herd and their animals. Women in pastoralist communities are responsible for domestic water collection, but they are largely excluded from decision-making about natural resources under traditional systems. Their access rights to water are secondary, meaning that port livestock get watered first, and women may have long waiting times before they can draw water from a dirty, muddied water pan, dam or trough. As with any development intervention, water investments are embedded in local power dynamics at the village level too. We need to consider power within the community. Once again, it is attention to governance, attendance to who participates in decision-making that is key to climate-resilient, equitable, socially inclusive outcomes. When designing local community planning institutions through the CCCF approach, IIED has engaged with these unequal gender dynamics in a number of ways. For example, individuals did not need to be literate to qualify for election to community planning committees, something that often bars women from participating. And prior to each election, the community was sensitized to the importance and relevance of having women on the committees. Once elected, members received special training and capacity building to build their skills. That's essential for pastoralist women who lack the confidence and skills for public engagement. The measures weren't perfect. As we all know, representation does not guarantee voice, and inequitable gender norms are still deeply entrenched in local pastoralist culture and traditions. But in communities in Wajir, the inclusion of women in planning processes led to very simple yet visible and effective changes in the design of the investments they selected. Changes that meant the needs of domestic water were also considered in addition to livestock's needs. The initial investment proposals that planning committees put together, they featured the usual fencing and protection of waterpans to prevent unregulated use of the source. You can see the problems that they were having in the before pictures at the left. They also included, these plans also included a pumping system and tanks to channel water outside the fence to troughs. And these troughs were originally intended primarily for livestock. But the inclusion of women's perspectives in the design phase led to alterations of the original plans. As you can see in these photos from Vargadot and the lagbok called waterpans, the piping systems were also made to serve a dedicated water kiosk with taps for women collecting domestic water. This one innovation addressed both gender and health issues in one go. The point is not that the design was completely new. This has been done elsewhere in many different places. But to point out how we can use water investment planning and governance as an entry point for addressing issues of power within the community and we can achieve very real results. The case studies we have seen from the drylands show how deeply embedded water investments are in local power dynamics and political contexts. Investments that ignore these local contexts can undermine local people livelihood systems, degrade the environment, trigger social tensions and exacerbate poverty. But the case studies also show the potential for using water governance and planning as an entry point for challenging structural inequalities and power imbalances. It can be used to address historic and ongoing marginalization. It can help to build sustainable livelihoods and it can strengthen the climate resilience of the most exposed social groups. This brings us to some fundamental principles that have informed IID's work on governance and local government planning in the drylands in Kenya and elsewhere. Firstly, there's a basic need to understand and respect the logic of existing land use and systems of resource governance, recognizing how critical they are to sustainable livelihoods and climate resilience. Relatedly, there's a need to take a systemic and holistic approach rather than a sectoral one. The planners need to appreciate the complex interlinkages between the resources in the environment, the livelihood systems that depend on them and the institutions that mediate access to these resources. This implies, thirdly, that there needs to be a landscape approach to planning. We should consider the full geographical area within which pastoralism is being practiced, the migration shed, if you will. Administrative and national boundaries often do not match the pastoralist patterns of resource use and seasonal mobility, so planning cannot stop at an artificial boundary. Fourthly, subsidiarity. In rural areas, local people depend heavily on natural resources such as water. They understand their environment intimately and they experience the impacts of climate change most directly. Decision making about water resources should be locally led, taken at the lowest feasible level by the communities that depend on those resources. Fifthly, the formal planning system should work hand in hand with informal traditional systems and institutions to determine and understand the priorities of local people and to encourage solutions that go with the grain of local context and conditions. This is easiest to achieve in countries where devolution has been implemented. And lastly, we need to remember power dynamics at the community level. East African pastoralist societies are gerontocratic. Women and young people have distinctive development and climate resilience priorities, but they are often excluded from decision making. Socially just and climate resilient outcomes can only be achieved by addressing this power imbalance.
