I'm gonna have to do it Very bad connection You have to just let it Canada Canada love Canada That's so stereotypical We need to We're in a sandpaper over this one more time Newport news It's right under there. It's under that Hi y'all you should get me a wine. Thanks 6 o'clock here you guys that you know what that means. It's time for resin and into the day drinks because I'm an adult with pigtails. It's 9 a.m. Oh Sorry, I'm just standing this down. We prepped it as usual so that it's Less likely to dip in the middle Margaritas Sippy sip for sure. I mean my city It is and Friday means We're doing question and answer today. So if you guys have any questions, I would love to answer This is just a 220 grit sandpaper We painted it with just regular interior flat White House paint Dry sand and that's how we prep we usually do this before We pour on it this piece. Thank you so much. This is I'm working on my name for her but tentatively it's a birth up because she's massive so it's um, I Haven't resented her yet. I haven't gotten up the nerve to do it because she's gonna take a Probably half a gallon She's a gallery wrap canvas The artwork goes all the way around She looks like there's and I'm working on I'm moving so I'm moving slow. I'm working on another one because a few of you have requested a tutorial on it This is where we're at with this. I'm gonna post the whole thing all together at the same time when I'm done with her And of course, I will put it on the channel for you guys. I Know someone said something out. Thanks y'all It's like magic. Just sippy sips appear for me Sippy sips So we can't see we can't mm-hmm. I don't want to turn the iPad on because it's gonna take extra bandwidth so upstate New York awesome for larger pieces it's harder to like control Our like spray paint caps to keep it up off our surface So we just put push pins Into the back so that it gives us something to pick up from It's not the most fun Put these in But we got these steel and so it works. It's still it's still not fun, but it works if you push Sorry you guys, I know it keeps freezing our building is not ideal for Anything new age like the internet so like I was saying we're using in Viratex light for our poor today Yeah, we're just using in Viratex light The colors that we're using I'm gonna start putting poles like surveys and the videos and So you say excuse you whatever dude I'm gonna put surveys and poles in the videos to find out what you guys want to see in terms of like color canvas size new resin techniques or things that I consider new because I've never seen them before So yeah, that's gonna happen I put I put one in the video we posted this morning so Today we're gonna do Lavender Mayeron. I That's what that one in copper. We didn't get those two, but it's on our to-get list. Somebody's sending us some copper Oh, yeah, someone is sending us copper. Someone's sending us copper and someone's sending us some gold Mayeron Can we talk about how we ship them? What we do is we take this guy. This is something that we gotta like Was that you all but you can probably order it online It's basically saran wrap on a stick and so We will wrap the paintings up all the way around and then we have these like this foam sheets that you can get at What's that place? Home Depot? and we'll put that over the top and Depending on how far it's going we'll add like popcorn Isn't that called popcorn the foam? Little fun things what if I pour I just did one and one so that's two Okay, so then what and then I pour it to three this one to three. Okay, so then for the other one Looks like you poured it to four. I did okay, so then pour it to three Check and see how much you have in each of them should even out so Then we'll add a little styrofoam popcorn things or packing paper and Ship them off the brilliant thing about resin is be it's even all the way across right now So the brilliant thing about resin is it's so durable We actually package our like portrait work, but what's wrong if I put it this is the great thing about doing this live If I I'm pretty sure I did it to there to there. Yeah, and then I poured from we're not sure if we have the right proportions Then I poured it from here to here a Good way to know if you have poured too much of one or the other. It's just look at the bottles It's all even all the way across So like not Hey guys The containers are so confusing sometimes. No, it's not the container. I just Ellen said that she it's confused on you Well, this has it it has it one to one, but I Just didn't know if I if it's there's already You know this much in here and I ported this much shouldn't I ported that much? I Would say yes, but since everything's even in the bottles I would imagine that we're gonna experiment together y'all. This is gonna be room.  It's gonna be amazing You should be at four Jeff for oh if you can read the containers through BTV better than We can't in person. I'm gonna be sad and very amazed. Yeah, baby. He's science. He's science Anyways, it's um brilliant and downtown Dallas other than the fact that it's it's like sprinkling right now Yeah, it's a little bit rainy time. Okay I'm gonna take the camera away from from here in a minute so you guys can get a full picture of what's going on The colors that we're using I'm gonna add to the bottom. Nope I'll add everything in the description box below, but let's Get a better view for you guys. I promise. I won't be all over the place this time. Let's hope so The colors that we're using are Maui this is a pigment powder from Distinctive concrete concepts. I must always get that wrong. We're also using Lores pigment paste This is amazing super easy cells if you're looking for a good pigment paste that is amazing also sapphire blue epoxy pigment paste Aqua ink You're so cute Jeff, I would agree And this mural marker In a color Calypso You know what? With alcohol on it not me. Yes me. Okay. Just for a minute. We're just putting down a layer right now the top layer No idea So You made it. I'm glad you made it Marjorie. It is a big one Bonnie But um, we've been wanting to do a larger pour since we did the big red one The 24 by 24 not too long ago Which is in a show right now by the way. Hi keys. We're great. You Use a Joe with resin Set in the bottom and didn't notice so That's true Susan Rona, what's up? What one color do you hate to be? What one color do you hate to work with the most but seem to be asked to use the most often be? I would say yellow Like yellow is just so But I guess you just have to use it in the right like the right setting With the right other really get a lot of people asking us to use different colors That's why we were we kind of asked that today like what colors would you like to see? I know you guys get sick of seeing teals and stuff. I'm sure I don't know that people do get tired of seeing teals because Like of our videos. Those are the most watched. Hi Marjorie. I did do that painting it was Inspired by an artist. I think she goes by blueberry glitter She does a lot of this type of stuff and I was super inspired to give it a shot this painting goes by Bertha she is on a 48 by 48 gallery rock canvas. She's ink and gold leaf And I'm working on a tutorial for you guys on that process as we speak I'm gonna resin her when I get up the nerve to Mix up that much resin Rono we basically are family now. I think everybody agrees that yellow is hated yellow and gray Yellow and gray will make everything mud every time how people use gray and it looks good Gunmetal gray looks okay. What else? I'm trying to think of the questions I'm glad you made it and I'm trying to think of what other questions I've been asked But I'm forgetful Also, this is how this piece turned out from yesterday She turned out really nice We're gonna finish the back off and post her For sale, it's super bright colors look great on camera and in person. That was with the silver Thanks Marjorie. I should have the ink tutorial for a painting like that In the next couple days. Hi Lisa. Welcome to the channel You should totally try coasters first. It's it's probably One of the first things that we tried with resin as opposed to just an acrylic pour Can use acrylic ink as a colorant and resin you can use almost anything to tent resin We have spray paints acrylic paints inks powders Micas Glitters we have all the things I Would not recommend using Oil paints because I did that one time in the painting literally leaked out somebody say on the my floor I Think this stuff is oil-based. It is Kind of it's an epoxy paste But it's not as oily as Oil paints Anyways, so yeah, you can use acrylic ink as a colorant I would just pour designs. Let's let's for one time not do like a solid puddle pour How much resin are we using? It was like maybe Four or eight ounces right now. We're gonna need more though. That's yeah, we're gonna need more for sure What's up, Megan? We're gonna be using those small canvases that you sent us probably this weekend Jessica, we do enjoy doing the live feed. I did want to ask you guys. Thank you for saying that Do you guys enjoy the live feeds? Or Or do you prefer the uploads better? Let me know this painting is sized Looks like you're gonna make a big dolla sign What size is this 18 by 30 nope 12 by 36? I Sanded a resin painting, but there's a spot on it that looks like a wet spot kind of like when you put a cup on wood And the condensation makes that mark will it go away Patty can you send me a picture of it? Just so I'm sure of what you're talking about and I give you the right advice for that Um It's what it sounds like what I want to make sure before I give any kind of Advice on that So send it to Thornton at artists till death comm I'll it's in every description box our email address Or someone can just type it up For you guys to see right now That's a huge studio Bonnie. It's a good size. We enjoy it. It's basically it's our home two-thirds of it is studio and then the other Third that would make sense is a our living space Karen wants to know what is the difference between Micah and powders? Not much I don't know I think one of them is This What would it be it would be like more course I guess it is not a little more metallic II Let me show you what raw Micah looks like Here's some chunks of Micah Focus so this is Micah in a large flake form. I hope you guys can see it It looks a little bit like goldfish food or any fish I guess Um Basically, this is ground up to make a Micah powder. Also, I have heard that you shouldn't breathe in Micah powder So use them with a respirator. I've seen people use food coloring and gels as well. It's something I want to test out And I'm here for whenever you remember The question I Saw someone spray silicone on a resin pour cool effects, but I'm sure was pitted everywhere Tammy That is so true. That is basically what Resi blast is and the cleanup behind using it is a pain 100% have to do at least one top coat Megan we didn't go to the 7 for $10 canvases at Michael's sale today. We haven't even left the studio. We accidentally Decided to go out last night So we didn't do much today People love the live feeds love them love them yes live yes live my second on the love them love the live feeds So now we have our answer Live and upload anything ATD Tammy you make my heart happy You tell Nathan to stop it with the rain dances miss Megan You getting bubbles? Yeah, and I'm pretty sure that's not good to breathe in those little resin bubbles When you thin the resin by Putting the bottles into hot water It reduces That but we didn't want it to be too thin since we're working on such a large space When will we see the ATD TV show I'm working on it kind of a strange questions Kind of strange having questions answered right away, but I really enjoy the live feed You guys are so awesome to watch. Well, that's the whole point like we actually get the The questions right away, and they don't get lost in other comments and Comment comments like that's one thing that I Know I don't miss them when we do it like this.  Susan um and This and do I have anything else in this paint? We need to start an art channel like the Food Network. That's true. I'm still waiting on YouTube to have like an art Section like they do music and gaming and all that Hi Becky Patty you can send it to the Facebook page email whatever you're comfortable with We'll get it either way Mayeron is super fine. I'm not even sure what that's made up. That's a Micah, isn't it the mayor on I don't know because it's just a powder like it's it's it's It's makeup. So I honestly I do not know So making Micah's work awesome and resin and are much cheaper. I'll have to look into that. Thank you very much. Ms. Tammy Hi, kaley.  That's horrible Yes, absolutely. Accidentally It was an accident. We had a couple drinks while doing the pour last night and then someone messaged me and said You should come out to the show and I said sure and then we got home at 2 a.m Complete accident Dry pigments play out when I pour using acrylic paint doesn't do that every different type of paint and even every different type of color of every different type of paint acts differently so You kind of just have to find something you like and roll with it Sippy sip Where's mine? This Cheers Do you guys do art full-time or do you have other jobs? This is our this is our job. This is what we do All of the days every day It's not a job if you enjoy doing it every single day That's also true. I used to have a grown-up job, but jeff has always been an artist Lemonade does count as a sippy sippy miss jan Is the rostoleum gold and acrylic based paint it is Montana makes that you know mine. No, but the rostoleum gold. It's not it is It's like an enamel it's regular spray paint Yeah, it is not acrylic based montana does make an acrylic based paint If you love what you do, you never work a day in your life. That is fact When I first met jeff. He was like, yeah, I'm an artist. I was like, okay, but no, but what do you do? He was like I art I was like, well, but how do you pay your bills? And he showed me and now I art too We art all over the place as a matter of fact I love these colors too. I'm always all about the sea colors. This is different for me right now I'm having a small little anxiety What's that you said a couple videos ago Don't stress It's gonna happen either way just do it It's a little bit stressful working with resin because you have a time crunch I'm trying to move slow so that the camera can keep up. What was that? It sank. I think that was ink But it is now under the clear Are you gonna tilt? I am Where's mine this One more shout out to all the donors of the channel. We're gonna be doing A giveaway for you guys on April 22nd. I will have a live feed on that as well Sue said I've noticed you don't seem to use a torch anymore, but rather use the heat gun Here's the thing. It's a little It's a little more easier just grabbing it turning it on and I like using the torch for like bigger areas so that you don't have to worry about the cord but Jeff prefers the torch.  I haven't and if you could send me a link on it, I'd be happy to look into it and see what's up That's beautiful right there. I love all that Do you all use both polycrylic and the verithane triple thick is one better than the other? I say for wood panels Versus vases Nope wood panels versus canvases when applying it We Don't use polycrylic or triple thick when we're doing Canvases because they don't need to be sealed and we sand it so it doesn't need a bonding agent Which is the main purpose of this is gorgeous. Sorry. I'm distracted. Which is the main purpose of The uh the bonding primer And the polycrylic is meant to seal in the Wood panels or wood dials that we use so polycrylic is definitely almost necessary when we do anything on wood and When we do bar tops and things like that is when we like Must have with the uh the bonding primer How fun is that? I hope that wasn't too jumbled. I'm trying to not get distracted with art while talking to you guys Do you find letting the resin flow over the edges then taping the edges? Teresa um We really like the organic look of resin going over and like continuing the piece most of our clients prefer that as well, so We will tape the edges and do it that way But most of the time We like this this look Judy said start over. I missed the start. Sorry Judy Judy that jokes All you missed was that we were not sure if we measured the resin correctly rich. I still think that we didn't but We'll see. Thank you Dennis. Hey Paula Somebody get that man a straw. I'm on it straw department. I said it right There how gorgeous is that? I can't even touch those pigment pastes y'all Thank you so much. Jessica Does the heat gun and the torch basically? Have the same degree of heat and power. Um, it depends. I actually wondered about that. I wondered if That is so pretty. I can't even handle it right now See this is gonna be one of my favorite pieces of all time. I'm pretty sure um They do vary and the thing I like about a heat gun over torches that it's blowing You don't just like the negative space. Oh, you're doing that The thing about the torch is it's blowing heat out. So it's got that little bit of movement When it blows the heat out. So I like that aspect because it'll push The resin around for me But the uh Jeff prefers the torch just because it doesn't have a cord and he has more control about the pinpointed areas where the heat is applied Dennis said you're such a good servant Erica. I think of it more like an assistant. I'm his van a white so to speak Yeah Let me reword that to seal the wood before applying resin should I use polycrylic or the triple thick is there a difference? um, there is a difference but Since we base most of our wood pieces in white anyways, we'll end up using both on wood. We use the polycrylic to seal in um any areas in the wood that may um let air through But you know, I think the bonding primer does the same thing because it's used to um Re seal Areas that have like paint chipping and stuff like that. So it probably do the same thing Basically do at least one of those on the front sides and back of your wood pieces Fabulous loving it while that's gorgeous. I need to order that white and you really do Laura can assist you with um, she's not even on this I think she's busy today. I'm hoping Murphy is doing well.  It is also the brand of the blue Which is doing much the same cell business as you can see What else we got? I hope you make it right because this is a winner. I agree And basically since our bottles are even I'm gonna say that It's fine. I'm assuming that it did Lisa asks how long have you been working in resin as a medium? Also, that is absolutely stunning work We have been working with resin since What would you say like seven months? Seven months. Let's just we just need to go back to our other To the videos and just look at them I'm not gonna want to sell this piece. I'm pretty positive. I love it I went on the la res site today and didn't see the white or the red paste. I got to find out what's up with that Paul, I'm not really sure but um I'll figure it out and I'll just add a link once I post this video. I'll find a link to the specific colors on la res and Just make that easier Oh, how pretty I need to I need to show the people I want to do a white on white So okay, so look so can you guys see in there how the white is over the base white? So we did clear as we always do and then the white over it gives that contrast because The white that we base it in was um kills, which is obviously a different shade of white But that looks Super fun It's funny because I don't mind blowing on it like The straw it it pinpoints an area and then it It makes such a don't break that distortion Look at that I love this clear and this white I love this whole piece How do you get the very fine lines of color mine spread out a lot? We don't have any fine lines in this one. I don't think it looks like they're fine lines when when you tilt in them And then it kind of gather gathers and then you tilt it back so that it just kind of sticks together Or it'll it'll it'll what you call it just it'll Come together and then it'll just kind of move it'll start dripping together So then it gives it a thin line which we have no control over If you send me a screenshot to our email Or dm or facebook or however Of what look you're trying to achieve I can try to help you figure that out as best I can. I know isn't it stunning right there? Oh if she's out of the material she'll take it off the site What would be the brand name of a bonding primer for me to look at as an example? We use triple thick a lot and kills has Its version as well All right, we're gonna do a little what are we doing on this one a little bit darker to fill in Because I wanted to get like this but with the teal that looks it looks really washed out I so I'm just I like it. I know but I want to just put It's not going to harm it.  Do you have going on right there? Lou I agree. It's definitely one of the best we've done so far. Love the dimension in depth. That's what she said Oh Bonnie just threw that out. I I agree Teresa. It's beautiful So amazing to watch it come to life. Gorgeous. Can you use your airbrush with just the air? Thank you for that question, Judy. You can And we have we have we've done it in like one video. We'll do another one Um If you try that at home make sure that you turn down your compressor to how many If you have it turned up all the way it'll just blow everything off of your surface Now we're just we're mixing color we're experimenting here people experimenting If something happens to this piece, I'm I'm not going to be able to sleep Can you put the name of the colors of the brands at the bottom? Yes, ma'am as Susan I will list all of These guys In the description box below if you watch any of my videos and want to know what I used You can always look in those the description box I add a link to everything It's a link to amazon You absolutely don't have to buy from amazon, but I figure it helps people when you know you get a visual of What i'm using This is my favorite piece so far. Love it. Thank you miss sue I have to start giving my pieces A blow Mm-hmm That's what she said. I love it when it gets a little Like it goes darker We do sign all of our work um where we sign it depends on What kind of piece it is if it's a portrait like when he finishes this piece he'll sign it right in here This piece i'll probably sign on the side Basically how this goes is If it's evidence How it should be hung up like you wouldn't hang this one upside down. I wouldn't who knows how a buyer would hang it but If it's evident then we'll sign it right here If it's not evident like a poor or I don't know what to call this type of piece We'll sign it on the side And it'll be signed on the bottom right of how we would prefer it to be hung so If we like it best this way We'll sign it right here if we like it best this way We'll sign it right here So on and so forth And etc Paul I completely agree. I don't understand why there isn't more sharing In the resin community Because honestly, I couldn't recreate this Exactly If I tried We could put a whole another board down Do the exact same way And it wouldn't turn out the same So Showing the sides like where it's negative. It's negative where it's the color. It's the color Like I could probably go in there and put it Don't mess with it. You can tell this is stiffen a little bit because of the The white edges, but since it's white in the piece. I don't have a problem with it So that's why most of the time we don't tape the sides. I love that. I love I like it would drive me crazy if there was like A spot of teal or blue or something in there because I don't This is what I love. I love when it all blends and sells And this is one of my favorites I don't know where I was Paul Oh, yeah People should share more who am I to keep someone from arting because They're intimidated with the materials I would hate to be that person And since I had so many doors slammed in my face quite literally when I wanted to learn I decided I would unveil the tricks of the trade Megan, I'm so sorry Next time we see you or next time we come through Dallas. Just let us know come by the studio and we'll sign it Signed one That was Megan that came by and dropped us Um Those campuses and stir sticks at the arts festival I forgot to sign that piece Thank you so much Brenda.  You've earned it. I'm going to do it right now. Sippy sip. Wait Hey You guys I got these glasses for Christmas and they have like oil Slate like looking color on it. I love it. I love them. I got it from my brother Okay, it's wonderful to see what other artists create so much fun. Lacing is beautiful. Thank you so much Susan. I agree Cheers. Cheers. Cheers you guys. Okay No, we're gonna have to put it under this So i'm gonna do a slow pan over it so you guys can see The amazingness I hope it's super clear I'm trying to move super slow.  I don't want to risk bumping the sides though There's also some metallic in here. There's some of it this There's Medium blue Is all metallic so it'll be sparkly when it sets up. Okay back to the tour of the piece B, it's a heart We need to start taking pictures of certain spots like this that would be so sick for a photo print I know Do you guys buy prints? Don't move the camera so fast, baby.  Let's do one of the squares The section is fabulous cheers cheers clink Silly question. What do you use to sign the piece permanent marker? Negative. Let me show you what we use Follow me to my office Here we are in my office so we use Paint pens like this is i'll link the The amazon link to these in the comment box or no description box. It's by pen touch for the most part They have silver and gold Sounds like a christmas song But we use those to sign it because we usually have some kind of metallic Gold or silver in the piece So this one for example will sign it and probably silver I Lied Jeff always signs it in gold. It'll probably end up being gold Barrier reef look i'm gonna scuba dive the barrier reef one day type it up I mean i've done parts of it, but i want to do the australian parts of it One for the record books one of the nicest i've seen well done both omg Is this just three colors so damn pretty no ma'am it is one two three four five colors um, it's those And this which i will link all in the description box Judy says so damn pretty i agree Thanks to you guys Nathan says you should make phone cases funny story. I'm thinking about it This is our super secure dust free zone. It's none of those things, but it is wrapped in plastic And out of the way And hopefully secure pink What else That white is amazing dude. I know i'm i need to order some more since apparently it's selling out all over the place So what dallas looks like today? I've got a wall that this piece would look amazing on So it will be more sale ellen says she would buy prints lots of people buy macros agree judy You should do like macro shots. I Will love to do that. I just need to get a camera Like right now we do everything on camera phone and gopro I've gotten a lot of recommendations from you guys, especially miss Debra Cox has sent me information on cameras for in the future We're gonna get a gimbal Oh, what i want to get a gimbal this month a gimbal the uh, the little steady Oh a stabilization thing But that's not a camera I know Dennis said do white on white Just love it. Oh, how pretty I already Sue said I would love to send us a dm miss you That's my mom's name by the way. So I love it Do prints you could sell prints of the whole painting so more people could have the same image That's true You guys I also found out recently that once you start doing prints You're supposed to raise the price of the original piece because it's an original So if you do arts and you do prints Note that a little bit It's just a nugget of information nugget watch out for the sharks, right? They're gonna jump out I love it finally get to watch the live feed when it's live hi from w state Finally Barbara I'm glad you got to show up today Nope tune in I'm about to do a phone case. I have a burgundy request. I love working with burgundies. Obviously. Oh Miss Judy this is where I'm at so far on The Tutorial that I'm doing for you. I just have to darken in some of the red parts add the gold and then I'll be posting the video in the next couple of days Also, send me a message and let me know what time nope what day would be best to come by Next week you shouldn't make phone cases. I need one Y'all I have one right here Ready to go. I just I've wanted to stone it with some crystals. So We'll see How much for a piece like that? I would say probably like 375 For that piece You had 375 on big red and it's 24 by 24. Well, that's 12 like 36 so I don't know Babe you tell them Judy now have a request from a 10 year old Judy Nathan wants a phone case I think emory does I think you're right. I think she does Do them I think she's on patreon and one of those other Websites where you can upload your images and people can buy All of the things with that image my problem with those websites is you only get like I think the most I saw was like 60 percent Of the profits, which when you're just Turning profit you're not giving anything out and they do all the work and front all the materials that's Okay, I guess but Also, you lose the rights to the work. So that's not fun Just found you guys and came to check it only to find live so excited. Thank you so much tracy My pleasure miss judy The crystals would be lovely. That's true Hanging with tody said 375 is too treat too cheap 500 easy Judy you're gonna do an iphone like Pour on an actual phone I would tune in for that all day All day And riz on edsie She's on everything She's got her art hustle Down pat for sure One day. I'm gonna get a shout out on her channel I look up to her. She Was one of the people I watched when I first started in acrylic pouring her and melody were The people that I tuned into like every day If she gave us this shout out on her channel I'd probably fall out of my chair and drop my wine and I never dropped my wine Oh, just the case. I think that one is an iphone case. I'm pretty sure I think I got an iphone case just in case it doesn't sell. I have something pretty and blingy to just have I'm glad you found us miss candy Debbie coals. I'll have to look them up I don't I'm probably have seen them, but I don't know Surprise visit from gold everybody give it up for gold They are tiles I'll show you one in a minute So we do this we just do this a lot with jacquard pigment powders the Perlex We'll just like blow it over the top and then hit it with some heat and it should sell out But I've we haven't tried it with marron no idea Careful you'll end up doing a million cases ellen honestly A million cases at like ten dollars a pop even Would be look at that money in the bank. That's money in the bank right there That looks like a cenote Makes me want to go to mehiko Very lovely Debbie retired for health reasons Hopefully her channel's still live and I can check it out I'm just learning what is the purpose of blowing on the resin Spreading it making it do stuff like this Like how it does that um heat this and blow it just so that They can see what's up So it gives it a different look and it I'm gonna blow right here so when you blow it it's like flowers and fades out like this And that's where the cells are gonna show up when it thins up. Oh, I just put my finger in that Oops Anyways, see the cells popping up. You may have a new technique on our hands It's so amazing seeing like in major resin groups and and like all these facebook groups people are like Oh my god, may run may run may run, and I'm pretty sure we were the first Someone proved me wrong I feel like I contributed to the art community as a whole because we actually sent may run a message too And they read it that didn't respond I know trying to get more stuff to test for you guys Oh the coasters so yeah We buy them like by the case and they're just plain white tiles And we resin them up and We usually do them for like whatever we have left over and then Let me show you some completed ones So these are some completed ones We'll sand down the backs and spray paint them to match whatever color it is And then we put these like felt buttons on them so that it doesn't scratch anything And that's coasters. This is Something we do when we have leftover resin in order to stock up for our next show because You can make your money back just on coasters from the cost of doing an event Anyways, I hope that answers your question about blowing on it Do you guys sell your coasters as sets or do you sell them individually? Well, this is the thing. Okay Okay We sold them in sets for Before this weekend because we just figured You want to set you know matches or goes with your couch or some artwork or pillows or whatever Um, you would think that people would want to set We had all our coasters out in sets And people kept picking up Random ones putting them together and I was like You have to buy them in sets like you have to they're in sets for a reason like And they're like, oh, okay So then we had just a bunch of randoms and we said mix and match So they still kept picking up The ones in the sets and we're like just eff it. Let's let's just put make we just put them all out mix and match All gone all of them gone But like 10 I think yeah, we have 10 left of like 120 I'm pretty sure so We sell like ones that we just do Like we pick the colors we do them up and people just buy them off the rack basically those ones Are 40 for a set of four um, we do custom ones for 50 for a set of four and If you want to buy them individually we can we do that that way too That's a very interesting looking Mayeron owes you I would agree Tracy. I would agree You completely contributed that makes my heart happy I'm just playing right now That's how you can discover a new amazing technique just by just playing He's just blowing that over If you do decide to do this technique That used to be like a little mound of blue until he blew it off Don't leave a mouth your finger because it doesn't do cute things That's really not cute, but Kelly you made it. What's up? So fun That's what blows my mind about these coasters is it doesn't go off the edge Like would know about mayeron if it wasn't for y'all. Do y'all ever work with alcohol inks solely as a medium? I have done alcohol inks. Let me take you over to my hobby hole This piece is an alcohol ink piece that I'm not sure how I want to finish I was inspired by somebody that posted on facebook and their link is in the description box of the making of this piece This is like No, like it's in the making of the the cherry blossom This is a big panel of masonite and It's just white masonite. It's basically a dry erase board that I had cut into different sections And it's alcohol ink. I keep meaning to do another one. I just haven't gotten around to it yet If you don't sign the back of your coasters, you should we're thinking about getting like stickers or a stamp for our coasters Those of you that are new to resin if you get black this black Tarp Just cut it put it down and I watch you ready completely comes up And I spend a whole afternoon doing this it comes off your spray paint counts too Look at that So much fun if you guys do anything with skins and you want these You have them we have skins all the time, but I Had I know nothing about anything has to do with that so to send us like An envelope with a return envelope in it and you can have have skins have them Toledo, Ohio. We've never been to Ohio. We need to do that I have an art fair next month. I wasn't sure if I should just set them out of sets Um people like to make some match if you want to this is one thing that you could do that I saw other artists do take a little twine Time up put a price tag on them if you want to do them and Mix and match just lay them all out together like that's that's the best put a big sign And if you have you know certain ones that you you know spend more time on and they have to be a set Put excluding this this and that Didn't we have that? Yeah somewhere Are the small round panels mdf. Barbara are you talking about these guys? If you're talking about this no, this is like press paper like cardboard type Thing I can also link if you guys want to see that We were testing them as coasters to see if they would warp and they did not So this is a great inexpensive also another great thing to have it like arts fairs and festivals Thank you so much Kelly for the compliments Rona it is fun to peel off sometimes. Um, I just kind of zone out while reading emails and just come over here and just clean these tables off And I don't want to Mace and I I didn't know you could use the air because that's lovely gonna have to look it up and these are the backs Paula I would highly recommend A lot of people use yuko paper, but I can't find anything big enough and it seems to like Wrinkle if you put heat on it for too long. So I always end up damaging the piece mace night Doesn't bow it does amazing this I know I see people making jewelry out of the skins, but I just I haven't got the time to learn a new craft right now How does thursday look for you judy wants to know if we can come up on thursday This thursday well it could be a week from yesterday. I think that sounds great miss judy just Shoot me your address. Nope. I already have your address. Never mind You could put your contact info on those discs and pass them out of shows. That's very true miss judy We could use them as kind of like A business card coaster If we can get smooth ones We're gonna just have jason print them on there. I heard that hot mugs stick to them terribly. Do you treat them with something? Here's the thing You have to have the right resin um The resin that we use for anything that's going to take any kind of hits or damage or have a lot of like Wear as opposed to like artwork. So if we do a table or a countertop Or a coaster will use Countertop epoxy this stuff you can get up to 500 degrees is scratch resistant uv resistant um Vacteria resistant is all the resistance ever made So this is what we use I I tested the heat threshold myself. I did I put my flat iron on it Dupo paper and tiles that I did one on the tile to I don't know where it is Oh in the bottom of this stack Dirty and dusty dirty and dusty I did a flammer Is it hard to sand the resin drops off the back of the tiles I have about 30 to do Um, it just it hurts your arm About it. It's time consuming We use our sander 60 to 80 grit You can use a orbital one Or Our regular one. Yeah, just a regular. We have two of them It's not hard to do. It just takes a minute wear a respirator because No point out to breathe that stuff in I was talking about those wrong things. Yeah, they're just like compressed paper They're not in the up like hold on like It's just But you'd think that since it's just like paper like this that It would warp at least a little bit But it did not but bars we ample pub uses these That people print on them and then basically they're just throw away coasters for them. Mm-hmm I mean in any ways coasters are made of that. So they soak up right Use a heat gun to remove the drips. That's true You can heat them up with a heat gun if it's within like a couple days You can heat it up and use like an exacto blade or a sharp knife To cut those off Amazing work my life. Have you ever mixed flotrol epoxy and acrylic paints all together for a pour? um We've got flotrol I have Jugs of it, but know about this one Um The point of flotrol is to get the paint to flow better. It's to like thin it out without diluting The color of the acrylic paint when you do a pour to my knowledge. I could be way wrong. It could be e-science um But when you mix acrylic paint into resin there's not really a need for it So I don't think I would do that with resin The more stuff you mix into it the riskier it is that it won't set properly because it's really scientific I would say it's just I didn't use them Fire and alcohol ink on tiles make some cool effects. I wonder how masonet would stand up to the flame edge I don't know. I haven't tried that. I will definitely Give it a shot for you guys if you like moupop What are you doing?  Good job Nailed it Okay, what else haven't we gone over? Tea welcome Tea No, not that tea Love your wee dog. Keep up the good work you guys Moose the best Yes, Bertha made an appearance. My living room is very lonely without her but Um, I've showed you guys an update on like I'm doing One of these for you guys. It's going to be just a regular Like upload because it's going to take So long to um Do all the different parts couldn't really do it live. So I'll have that uploaded next week Floatrol will turn your resin into blue noted.  Oh, um the candy paint Kelly We'll we'll do that test soon So for all of you late joiners, let me show you the pour that we did tonight Dun dun dun Look at that I know but I don't want to get in there Mess something up Because I would All right Tysie noted Um Hey me Does all in the camera It's like my cameo Rod, thank you for the donation Hey Thank you all the dollars count Resin's expensive y'all all the dollars Resin's expensive My hair's falling All right, does anybody else have any more questions for us? Anybody want to know anything? Oh, I wish to spell We all know I fall all the time Thoughts on color changing paints Uh, I would I agree. He is the cutest dog ever Um color changing paints. I know we have a couple of color shifting paints and they work well I want to order some from Can't remember the name right now, but it's Like also a car flake place But I haven't had a chance to order anything, but I'm going to order actual real life Not crafts paint that changes colors, but For real paint that changes colors Is it human? Thank you, Tysie Sure. He is a cute dog ever. He's amazing And he's looking at me like, yo We should go for it, don't we? Okay. Also, he can spell. So I had to whisper too Dip spade. Thank you, Judy. That's the place. I'm gonna try some of their I wonder if I can hear him like huffing and puffing at me Did you get to check my instagram? Um, yes rod. I have visited.  Solar color does have some interesting color changing pigments Thank you paul. I will check them out No I got your blue sparkly fun stuff today. I will put it in the mail Monday. You're sending me a present I'm getting presents Rod, you have a request to post your insta in the comments so that everybody can see See everybody wants to know If you guys want to see our instagram, it's at artists till death studios Yeah, any more questions you guys have When we cut I think we're gonna Do A um white on white or And then I'll post that tomorrow. We'll be back in the morning to let you know what time we'll be posting paula Thank you so much We're getting dollars. I love all the dollars dollars are my favorite. Um We'll be posting in the morning not from the roof because obviously that was a bust because the wind and My cell service or whatever it was just crappy up there Thank you, ellen It's my pleasure ticey Dennis tell your wife who said hi. It's our pleasure to share secrets with you guys It's our pleasure paul um If you have any requests for certain color combinations Leave them in the comments If you have requests on like certain paints you want us to try or a technique you want to see done Leave it in the comments. Have you heard of black 2.0 paint? It's made in england darkest black you can buy I didn't think you could buy that. Yeah, I thought the guy I thought the guy that made that judy was like no, thank you so much. Nobody can use it Didn't isn't didn't they say? Thanks judy. Thanks paula Oh And that goes to us right somebody said that they think that might go to youtube It does not go to youtube it goes to us and it's The same as like the ad stuff No, so the black is black I would love to use that. It was made just to challenge it. That's what I heard rod. Well, then the guy made Either the pink is pink. Yeah, this guy made the pink is pink he sold it but the reason why he sold it so that he Wouldn't allow the guy that made the blackest black to buy it I don't know how that would work, but that's how it that's how it would happen So I'm still trying to figure out.  What name would you like me to? Can you guys see my idols? Oh paula. I appreciate a dollar ten dollars all the same to me It'll buy some paint. Why are you doing that? You're ruining my thank yous. Thanks everybody. I can get some new glasses now Your eyes look really big. He's doing that on purpose. Have y'all ever seen the trailer park boys? It's on netflix. Check it out.  Why make something that nobody can purchase? Have questions, but we'll do another time bb. You can let us know questions anytime It doesn't have to be during a live video. I will answer all the things for you guys paul knows about bubbles Vanta black is darkest licensed to the artist.  I told you guys that he would warm up to the camera I don't like being on camera.  No, that was like two He was asked to be on like the skin wars type things. Thank you so much tracy um That's gonna hurt bad sound feedback on my video um who that's to be on like um Body paint competition body paint competition and something else He used to be on tour for body paint. He did the body art ball. Look it up this thing And he won every year except for one year. He got that was a competition I won twice got second place twice.  So I look like Arnold Schwarzenegger Because I have a masculine jaw line Do alcohol in space over time and if so how much time roughly they do you can use like A sealant I think that like extends the amount of time that they don't fade No idea on the amount of time it takes. I think it depends on whether you're in direct sunlight inside Exposed to whether there's so many factors. I don't even know if you could look it up I don't think there's an answer to that He's so funny. I know he's funny. He doesn't like to share his funny and as sometimes so Carol, thank you so much Um any more questions I can get to for you guys The boy is getting antsy you be protective. Thank you paul What's rad? Now is in like right now or now is in like just like turns out I want to do them Good night everybody. Thank you for tuning in It's our sincerest pleasure to share the secrets of the trade if you want to let us know what your artwork looks like tag us Um on anything. I'll leave all of our social media Things in the thing below also hashtag AR nope ATD ART when you post your artwork so we can make sure to see them Is that a giant prism a color marker behind you? It in fact is it is Because all professional artists should have one giant piece of this Where did we get that from? It's a display I mean who doesn't have one Oh, also we're thinking about doing like mystery boxes Yeah Like we'll do like a a mystery box like for 40 bucks It depends on how much I guess you'd want to spend on a mystery box You don't know what you're getting but you know you're getting Don't people usually do like a three-tier mystery box like this mystery box for this dollar This mystery box for this dollar this mystery box for this dollar Like you never know you could pay a lot of money and get birthday in the mail one day I'm not shipping birthday because that would that's We've shipped it 48 by 40. Oh, yeah The one that there was one in new york and then there was the one to houston It was like $400 I know right the white on white is going to be astounding. I think we're going to do that tonight Um, so yeah in the mystery boxes, we're going to like include things like paintings coasters um What is that? paint different types of paint basically I'm surprised it's a mystery. It's all things so but I didn't know if you guys were into that sort of thing But if you are just let me know and we'll put it in the works Also, if you ordered a painting from us from our last, this is what's available video They're going out tomorrow. I finally have all the email. Nope shipping addresses in And I also have boxes. So They'll be going out tomorrow How do you guys figure out shipping costs timmy? shipping costs. Um, I usually just ask everybody for their Um, zip code and I can estimate it In the fed it there's like a FedEx calculator I just have to estimate the size of box I'm going to need and how much it weighs and then It gives me a number Love the idea great idea Great idea. I would do that free free classes 100% interested in mystery box We're gonna we're thinking about doing classes like workshops in Dallas and then The end goal is to do like a tour Listen to me like we're some big deal. We're not a big deal, but I want to travel and do a class On our journey an adventure if you will. Yeah, just like a fun tour of different cities Or states or different countries Possibly countries anyways Yes, we're gonna go with something neat.  We're gonna do a live pour and also Yeah No, I was just thinking that time it was just my fault Anyways, thank you all for tuning in. Thank you for all the donations. You're so generous with us and it It makes artings so much easier And it keeps us off of those paid sites because I think those are pesky and I don't want to do that anyways and Um, yeah, I hope to see you guys tomorrow. Thank you so much for tuning in and everything you guys do for us Bye Bye


Right, Heat 20 coming up, big race needed here for Christoph Kasperzak, the wild card, and Bartosz Maastik still with a bit of work to do after a great night. Freddie Lindgren on nine, it's really superbly. And the reigning champion, Jason Doyle, looking for some consolation on four. Needs it, hasn't been his night, had a couple of exclusions, hasn't been that on the pace this evening. Here we go. Here we go into the first turn, it's a good start from Kasperzak. Oh, and Kasperzak's hit some drive and it's gone square. It's allowed Lindgren to come through. Charging through in blue, super ride from Bartosz Maastik. Freddie Lindgren, what a race, this is Lindgren and Maastik wheel to wheel. Get out of the way, says Freddie Lindgren. The man in yellow here is Jason Doyle as well. It's a right tear up here. It is indeed, that's exactly the right descriptive word, a tear up. Wow, Freddie Lindgren absolutely charging hard. Doyle fighting for his life. Maastik third place, probably won't be enough. Freddie Lindgren building nicely, Kasperzak fading away out the back. But for Freddie Lindgren, once again riding brilliantly out in front. Lindgren's going to top the pile of qualifiers on a dozen. He's going to have first pick of gate positions in the semi-finals. Freddie Lindgren, superb. Well, excellent from Frederick Lindgren with Jason Doyle in second spot. And third in blue, Bartosz Maastik. What a race that was. A tear up indeed, nice. Freddie Lindgren, superb in heat number 20.


Today, I wanted to share with you the ATUN, which is an AI-based automatic parameter tuning system. I will introduce ATUN from the following four aspects. First, I wanted to introduce what is the performance tuning. This is a simple example for matrix multiplication of 4,800 by 4,800. If we write it in Python language, it takes more than 660,000 seconds to run. However, if we use C language to write it, it only takes about 600 seconds to run. Then if we optimize by multi-switch parallel computing, then we can only take about 37 seconds. Then if we use other optimization algorithms such as vector instructions, it only needs to take 1.99 seconds. This simple example gave me a, we can say, let our Hoji room to improve our performance. Then I will give an instruction about ATUN. As we can say, operating systems have a large number of parameters and complicated correlations between links. However, those tunable parameters control all aspects of the operating system. For example, in Spark, there are so many tunable values. If we use the default values, they can't get the best performance. Now, we want to tune this parameter. For example, there are several advantages. For example, you can, the execution time of Spark can drop 10 times. And the system resource utilization could up to 10 times. And we can also reduce some errors such as OEM and timeout and so on. However, tunable parameters have several challenges. The first one is that there are many parameters in a single system. For example, in Spark, there are more than 200 parameters. Then the second one is the large number of systems. For example, there are so many applications such as the vertical applications, analytics and visualization systems. Different systems need different kinds of parameters. Then the second one is that there are diverse workloads on the system complexity. For example, even when we use Spark, there are all kinds of workloads. For example, there are including the ML labs, streaming, circle, and graph processing and so on. Different workloads also need a different kind of parameters. However, if we're using manual tuning to tune these parameters, there are several disadvantages. For example, it requires long tuning time and it requires individual appearance and has high level costs. However, if we use AI to automate the tuning, there are several advantages. For example, it only needs short tuning time and there is no need for individual appearance. And it only needs machine costs. Therefore, the object of ATUN is that giving an workload, we want to use AI to find the optimal parameters for giving workload and achieve the best performance. Now, let's see the related works. As we can see, tuning is a constant topic. In the 1980s, large manual tuning had been used. In the 2000s, statistical and hierarchical methods are widely used. Recently, in the 2010s, traditional machine learning methods are also widely used. Recently, deep learning and reinforced learning methods are also widely used. The following table gave the performance of all the load methods under several dimensions, such as quality efficiency and to deal with three challenges. As we can see, there is no single kind of method performed best under all the dimensions. Now, we want to use AI to perform the automatic tuning. Now, several advantages. The first one is that for standard coverage, we can leverage a variety of technologies to optimize several layers. The second advantage is the intelligent operation. We can implement tuning opportunities in efficient and intelligent manner. The third one is the target orientation. We can turn the system based on objects and constraints. The third one is the full automation. We can conduct the entire tuning plus schedule automatically. Now, we design an A8 tune, which we use AI in the optimal performance of the system. First, we need to collect all kinds of data, such as system metrics. For example, CPU utilization, and other data, such as framework specific and application specific metrics, and the target metrics. Then, all the metrics are sent to the A8 tune. A8 tune can make intelligent decision making and learn how to put an optimal load, such as system load, framework specific load, and application specific load. These of the magical logs can make the performance of the system better. Now, we will give an architecture of A8 tune. A8 tune analyze the research usage, such as computing, storage, and network of applications, or clouds, support parameter tuning for mainstream applications in the industry, and improve tuning efficiency. The architecture of A8 tune includes three parts. The first part is intelligent decision making, which includes online static tuning, and offline dynamic tuning. And the second part is system characterization, which includes the data platform, feature engineering, training, and inference. The last one is the system interaction, which includes the system full stack monitoring and configuration service. Now, I will give two parts of the offline, including online static tuning and offline dynamic tuning.  The scenario of online static tuning is the common uses and applications that are needed to be online at all time. The idea is that A8 tune detects the current application workload, matching it to a lower workload based on the classification model, and then outputs empirical parameters. The online static tuning has several key technologies. The first one is the important feature analysis. A8 tune can automatically select important features to characterize applications accurately, and it can have two layer classification, which can accurately identify the current workload. And the third one is the workload change detection. It can automatically identify the application workload changes and implement adaptive optimization. The second one is offline dynamic tuning. Offline dynamic tuning is for advanced users who have high performance requirements. The idea is that offline dynamic tuning includes three parts, include target device, curia, and workloads. The idea is that curia sets parameters for the target device, obtains feedback performance indicators, and it continuously obtains optimal parameters. Therefore, offline dynamic tuning also includes three key technologies. The first one is the important parameter selection. It can automatically select important parameters to reduce such space and improve training efficiency. The second one is optimization algorithm conjunction. It can allow users to select the optimal algorithm based on application scenarios, parameters, types, and performance requirements. The third one is logic-based conjunction. We can add a counter-organized territory text and an optimal parameter to the logic-based to improve subsequent training efficiency. Now, I will give an ATOIN implementation framework. The framework includes three parts. ATOIN server, ATOIN client, and ATOIN engine. The ATOIN server includes data collection tool and system configuration engineering. The ATOIN server must be installed on a target device. The ATOIN client is used to interact with the user and output the results. The ATOIN engine includes all algorithms of ATOIN, such as classification models, key parameter selection models, model training, and automatic parameter training. The three parts can be installed on different machines and they can communicate through the GRPC. Now, we will give several training results. For example, in Spark, there are several capable parameters. If we use that default value, they can get the best performance. Now, we want to use ATOIN to select the best values for the given workload. For example, after ATOIN training, the performance is improved by 30% over the default set-time configuration and 5% over the configuration optimized by professional engineers. The ATOIN efficiency is 5 times than that of manual training. Now, there are also several other training results. For example, we optimized the ETCD set-time with ATOIN in creating performance by more than 10% the results were displayed in the open-or-wire application protein condition. And we also optimized MySQL. MySQL is optimized in six different scenarios open-or-wire and not operate with mature machines with four cores and 60 get-byte memory as well as 32 cores and 64 get-byte memory. In OLTP in static scenario, the throughput is improved by 5 times. In the future, ATOIN will break performance bottlenecks. There are two kinds of improvements. For example, we want to from offline to online. There are several trends. For example, continuous performance training capabilities for online application to deliver performance as a service. For example, there are also several systems. For example, our ATOIN provides online parameter training for cloud databases. And the graduate focus on resource queue training for online applications. However, there are also switch changes. For example, the first change is called start. How do we deliver optimal performance in absence of history data when a new application goes on? The second change is adaptability. How can the cost of online training be reduced when a model is trained against online applications? That changes dynamically. The third one is security. How do we keep the performance of the immediate queueing results above the preset threshold to ensure high system availability during queueing? The second one is from yield mode to color mode. There are also several trends. For example, utilizing AI technologies to save the form, commission or certain configuration optimization to certain design optimization. There are also several papers. For example, LingOS uses AI to reconstruct the color block layer and predict the IO electricity boosting SDI performance. KML is another paper which builds an AI model in the color space to implement load-aware data perfection policies. However, there are also switch changes. The first challenge is computing overhead. How can model complexity and performance be balanced with the limited computing resources available in the color space? The second challenge is timely list. How do we infer and secure the highly dynamical optimization processes? In my second, the second one is university. How do we construct a universal framework for different optimization types that involve data collection and optimization algorithms for various color modules? Here is an A2N repository. Everyone can get a code of A2N. Please feel free to contact me if you have any questions. This is my email. Thank you.


Hello everyone, my name is John Hammond, and I am so excited to share with you guys a project that has been a labor of love For such a long time now. It's a project myself and my roommate Caleb have been working on for two years realistically, I guess the two years ago since I started kind of the living document of CTF Katana as a reference for some players that has got a lot of traction on my GitHub repository in One year since we started the code more so than that now over a year since we started the actual Repository for the software project of Katana that will attempt to automatically solve some basic beginner Capital flag challenges. So finally it is open source and available and free and ready for your use So I want to show you guys how you can download it get started with it all right now in this video So here we go Let's get my face over to the side on the screen And I'm gonna fire up a web browser because you can find this online on my GitHub repository if you go to github.com Slash John Hammond you can find all of my repositories. You can find the original CTF Katana Which is the living document for notes and guidelines back in February of 2018 of Some things you can try and do and work on for a capital flag challenge But now we also have Katana itself forward slash Katana The automatic CTF challenge solver that is written in Python 3 We're gonna have a stream probably later on Caleb and myself Showcasing this and doing things with it and exploring it and talking about it So hopefully we can answer any of your questions fingers crossed But we do have a couple notes in here that yes, this is meant to be an automatic capture the flag challenge solver with the disclaimer incredible disclaimer that This may suck this might not work. This isn't going to solve everything. There's no way this could solve everything This is something to try something to maybe help you that might Use a utility that you hadn't thought of to use or you might otherwise forget to do that is really the whole thesis of Katana and what it's always meant to be and admittedly it is not heavily maintained at the moment This was something that we were really really passionate about once we got starlin it once we wrote it once we were in the weeds But then life gets in the way as you know it always does It's funny if you actually take a look at the insights here if you go look at the contributions and things here You can see February 2019 we kind of kicked it off and there was a lot of development in those first couple months and then it peered out to Hey, I started a new job. I'm traveling Caleb's traveling We get a little bit more into it and then it fades in and out and become a little bit of a roller coaster So now we have got it to a point where we're happy with it the framework I hope is cool. It's really helpful for you guys. It's extensible You can hopefully solve things and add things in a quick and easy way But we make a note It is not heavily maintained because we will not always be readily available for things that need to be fixed or things That need to be changed or bugs or errors You might still find a couple bugs and errors or Python exceptions that are thrown out and rose and raised so Anyway, another disclaimer Katana will run Potentially bad and evil things will do malicious stuff because you are acting as a hacker or offensive Adversary in a capital flag scene typically so it will do Offensive things do not ever ever ever use this whatsoever at all against anything that you don't have the permission to test and operate on because Katana will Automatically recursively do things that could very well be bad So okay, this is the repository. I want to get it spun up And I want to show you guys how you can do it in a clean new virtual machine So I'm gonna fire this up in 1804 instance that I have running or 1904. Yeah, 1904. Sorry, and we have get installed here So I can get clone this I'm gonna make sure that I can actually you know what let's just type it Because it is public. It should not ask you for any credentials You should just be able to go ahead and download Katana and once you have it Downloaded you can go ahead and install it with everything that's already mentioned and discussed in the read me If you don't already have some of these packages, you'll want to go ahead and install them or update them These are just kind of convenience things and I'm showing this on Ubuntu for your use In case you are running on Ubuntu. I am and I figure that hey That's a pretty common one actually use and maybe you could use it in Cali, etc But we do not Venture out to offer your support for those other distributions. These are just what we developed on I wrote a new bunch to Caleb wrote an arch There were some comments to do that But I will show you the Docker container that will go ahead and do this very very easily soon Okay, now let's paste that in and fire it away. So There are obviously a lot of dependencies for what Katana uses because it needs a lot of different Python libraries and it also depends on some external tools or some of the regular utilities You might use in a capture the flag competition like bin walk like forensics foremost Exive tools steg solve z steg j steg snow, etc in tons of them in tons of them so Installing each of them is a little bit tougher to do when you end up running it actually on your own system Depending on you're gonna need to actually figure out the package manager or repository stuff to get all those tools Put them in your path so Katana can actually use them I have my machine already configured that way like my personal physical laptop. So does Caleb I'm sure a lot of other people already do that do capture the flag, but from a beer new machine While this is going through and installing a lot of things. It's not going to have all those things already set up It needs and pie it needs APK tool tons of these other external dependencies that Katana might use you might have to go through the process of actually tracking that all down So I'm gonna let this finish installing just so you can see the rest of the normal setup on a physical machine And then we'll roll into the docker container Okay, so the apt install command just finished running that took about five minutes on this virtual machine Now that that has been set up and created you do however need to go ahead and create a Virtual environment that you're gonna run Katana out of again I'm making sure you use the latest Python version at least three point seven in this case and you'll create a Environment virtual environment folder I pull from system site packages because we just installed debuffs I've actually had some issues where it's been trying to pull debuffs and it hasn't been able to but anyway We're just using the V and V environment or library module to create a virtual environment You should be able to do that because we installed that just fine And they'll activate it and actually install all of the dependencies for Python through PIP So that takes a lot more time as well. We can go ahead and slap these in though Now that's activated it and it will go ahead and compile and create Everything that it needs for Katana itself to work as a module I'll again pause the video because it takes a little bit of time for this to happen And I'll get back to you once the process is done Okay, that took about a minute on this virtual machine And now Katana should be installed and accessible and able to be used within this virtual machine You can typically invoke Katana in two ways if you have it installed as a module just as we just did now You could run Katana just like that as a command or you could also specify it as a module for it to run In our case we need to specify some arguments for this actually work with it needs to know the flag format that this CTF is going to end up working with or end up asking for so that can be specified with the attack F argument And we can just say kind of a regular expression right here. Let's just say flag is kind of the opening Header or prefix for all the flags and inside curly braces. We can have match anything So I use a period for any character Asterisk for as many of them as possible and I use a question mark to make that lazy because I want to find Just up until the first occurrence of that ending or closing curly brace. So let's run that But this will also yell at us now that it has ran previously It has created a results directory and Katana won't want to run if there are already results that Katana had previously From an earlier runtime or execution process because it doesn't want to clobber those So if you want to clobber those on your own Then you can run Katana with tack tack force and that will remove the results directory that was saved previously And now use it for just this runtime's results You may or may not want to do that depending on your actual Work that you do to her how often you use Katana for a CTF if you're using it with a CTF You might want to have it running and working alongside you just on and available And you'll see how that works once we get moving here, but let's run tack tack force But it will tell me hey, we're missing some dependencies and it will allow us to actually it'll still run Katana It'll work with us But it knows these are the dependencies that are missing and we won't be able to actually use those Because they're not available on our system. This does make things nice and easy for us though Because we're now working inside of Katana Katana has a couple commands or things we could actually use in this case, I actually just want to exit out because I want to Show you that syntax that we could just kind of copy and paste and steal from This read me here. Now the Katana has been installed. We can run it We can use tack tack force to remove the results directory specify flag format and here I'm supplying a target or what I'm actually trying to evaluate and have Katana work against in this case This is just some base 64 encoded rendition of that flag syntax So I can copy and paste this in and Katana will automatically detect. Hey, that's base 64 It'll decode that base 64 and it'll give us this flag and then it'll tell me hey We solved it as a quick notification that works nice and easy for us I could do the exact same thing if I want to specify this as a module So I'll say Python attack M and that will again run the same way But now it will kind of display out and work just as that if you wanted to do something again We saw in that help output. We have a couple options that we can run we actually also have commands like target and Target will allow us to view or add or kind of queue some new things that we're actually searching for Between that what we're trying to actually have Katana work through and run. So let's actually check out target List or LS as a quick shortcut. We had this that we supplied as a target Katana tells me it already finished it already ran through it and every single target that you run is going to have a unique Hash or its representation of how you're actually going to denote and reference that target again in your use of Katana If it found a flag it'll display it there for us But I want to show you this hash and how we can use it because we have those other options We can say targets just as we saw before we could view a specific hash I could paste that in or we could even just tab complete it and it'll show options if you had multiple targets And we could check out some of the JSON results or actual findings that kind of occurred when we were looking at this Specific target, so it tried to run the base 64 unit determined if it was base 64 It actually decoded successfully and found a flag through that it also tried to run a Caesar cipher And it looks like that's all it ran through because it already found the flag right away We could if we wanted to check out the solution for that target you could see Solution is an option Target solution and then again the hash and if we have multiple steps Maybe it was a base 64 to base 58 encoded thing We could then see all of that syntax or we could check out target flags again I'm gonna get it and see what flag came from that so that's just that simple target command that you run in the Interpreter of Katana you can hit control C or control D to break out of it You might hit control C again if you hit control D or just type exit to cleanly exit But that will close out Katana for us So okay, that was some quick usage, but I want to show you now the Docker image the Docker container if you don't have these dependencies like we saw and Pious snow J-Stag and some of those other things. I guess it's NP to people yell at me for that If you don't have these dependencies and you don't want to bother with them You can work with this Docker container This is all kind of explained described in the Docker directory inside of the repository go check this out Inside of this file. We have a inside this folder We have a Docker file which you could just simply run Docker build that just with keep in mind this takes a long time Because it's trying to okay grab all of these dependencies that you just saw work in our virtual machine even compile some of the other things that are necessary for the libraries and Go grab those other external dependencies that we don't even have in our virtual machine But you might want for a capture the flag competition. So we could do that with Docker. I'm gonna do this on my own physical machine now I'm gonna actually pivot to that. Let's CD Docker I'm sorry get into the Katana directory first and We have this Docker file here. So let's go ahead and Docker build Katana just like this and This is gonna take a bit of some time, but we'll go ahead and let it run Okay, so now the Docker image has successfully been built I do want to actually show you what this Docker file Sets up and builds and uses here. So I'll drag this over Let's like set that syntax to bash. So it's a little bit more color-oriented We're gonna use Python 3.8 to go ahead and pull this down from We grab all the same dependencies that we had used previously and we go ahead and install again Those other things like z-stag j-stag and pipe and p to snow Etc. Etc. And then we go ahead and grab the repository and stall everything This also works with a Katana.sh script the Katana.sh script is kind of handy Caleb put this together This will actually determine it. Hey Depending on since you've built this Docker image, let's go ahead and reach out to the github repository and see if there are any changes Because you may be running an old out-of-date version of this Docker instance or of this Docker image If that's the case it says, oh, we found some changes that the github has that's a little bit further ahead in the development We could actually pull this down and let you run with that copy of Katana It's not gonna end up running it and making it persistent It can't update Katana and keep it within that Docker instance You have to go rebuild that Docker image But at least for that quick temporary on-the-fly thing if you know hey You have an out-of-date rendition of Katana It will go ahead and pull that down for you or it'll say oh We have the updated most up-to-date and latest version of Katana then it won't Bother it'll say you're up to date But you will get notified. Hey if we have a newer version you can rebuild your Docker instance with just that same command that we ran earlier also Excuse me. It's running Katana, and it's also checking with some arguments here the katana.ini file so Katana works with I and I configuration files which help specify some of the arguments or parameters or settings that Katana might use For its own operations, so I'll show you some of these here in the examples director. We have a couple of them Here is a simple Example.ini where we just specify okay the manager that's working in the background of Katana needs to know what flag format this CTF Might end up using we also have a couple I and I files that are used for a for a specific case Like okay, maybe working against Pico CTF for a CTF Dnses, but I'll get into that in a later video I do want to just talk about how we can also specify other arguments for the monitor and how we can monitor Specific directories that you're working with inside of Katana or with Katana So maybe if you're working through a CTF and you download a file Katana will identify Oh, you downloaded this it'll automatically rip through it And if it finds a flag it'll even automatically submit it for you. So that's kind of neat and kind of cool So those are those I and I files will get more in depth on those soon I do want to show you this monitor functionality Let's go take a little another look at that read me though to see how it works Because when you run this instance, you can make it interactive and in terminal mode That's the IT arguments the tack V directory It's gonna end up sort of mounting one position in your file system to a position in the actual docker container So Katana in the docker instance works out of this forward slash data Directory and that's where it's going to look for targets automatically and store results in a results directory Automatically, so if you make any changes, you need to know Okay, that has to all work with that data directory that you might make So we could go ahead and test that if we wanted to let me Make a New I guess directory here in a new shell. Let's make directory temp Timo apparently that works just fine Timo So what we could do is we could docker run Let's actually make a data directory. Actually, let's let's see how it works without it I'm gonna end up using my present working directory Just as with some command substitution to specify that to slash data inside of the docker container We'll say tack IT for interactive in the terminal and then Katana as our instance name It knows that okay, this is the absolute latest one But we don't have that configuration file this data directory or this directory that we're working in needs to have a Katana dot I and I file so let me go ahead and create that I'll just say Katana dot I and I Manager the simplest rendition we can have sort of a flag format can equal Flag with anything in there Great Now if I were to try and run that one more time Katana is up to date fantastic It's gonna want to monitor that targets directory and it's doing that automatically. We actually have that command monitor We could check out monitor LS to see what we're monitoring right now We don't have anything in there because we don't have that actual directory created So let me stop Katana and let's make that directory targets Great, he's in there now when I run this from the current directory It should be able to not give us that warning. It won't tell us. Oh, we actually don't have the excuse me the targets directory, but because the Results directory is in there. We can't Run just yet. So let's say force can equal true inside of our katana that I and I file You could specify tack tack force as other arguments But the way that this docker instance works this docker container works is because the Command arguments that are being supplied it because they're already defined in that docker file if you supply tack tack force or tack F as other arguments Then it's not going to automatically pull at this katana dot I and I file or automatically use this Monitor setup it with the monitoring directories. So that's kind of a bummer it's not That big of a bar because honestly if you're using katana as a docker instance You should probably already have a directory all set up for that specific CTF and have a configuration file Already set up and configured for that CTF You shouldn't need any of these other arguments because everything should be contained inside of a Specific organized directory with its own specific and organized configuration file So now we can run this because we've ran tack force We've included that in our configuration file and now it is running and waiting for us So we could a monitor and check out what we're actually listening We do have monitoring capability in this directory targets that is inside of on our File system this targets directory. So I'll move in there. We know our flag format is Flag which is kind of curly braces So what I'll do is I'll have katana waiting in the background and let's say some new file Just suddenly appeared in my file system. Maybe I downloaded it. Maybe it was created But either way katana will monitor it and go ahead and create it. Let's echo flag This is a flag. I'll use tack and so I have no new line in that case Now, let's go ahead and pass that to base 64. Go ahead and pass it to base 58 and Now we have this string. Let's go ahead and create something. I'll call it like something dot text and Katana will automatically find it cue it and then it'll start to track it down and find the flag base 58 base 64 We found it Awesome katana did that all for us and it's running inside that docker instance Some of the issues that you might run to when you're running with the docker container is that you won't have your new Flags automatically pulled and copied into your clipboard You also won't find those desktop notifications that it'll explain when you actually saw the challenge like we kind of Just did that's okay because we do want you to be built out to the position where you don't need to use a stalker convenience Image, but you can it's available. It's meant for you as the end user If you don't want to pull down all these dependencies and add them to your path Obviously, we would recommend that though. So let me activate this environment in Activate now I can run katana. I will specify that configuration file that I just made katana.ini and We could manually go ahead and add that monitoring capability because that monitor command in here We can just simply add something we can simply say monitor add and it needs to know whether or not we can recurse on that If it's a directory everything inside of that directory as well Which might be handy for when you're using a again specified and designated folder for your CTF Well, let's go ahead and monitor add a tag tag recursive And I'll specify an absolute path here home John Timo targets good and Now that monitor list that's already set up for me I can go and create that file Once more and because that already existed it didn't do anything new with it So let's just say a new file dot text down here Katana We'll go ahead and run spin it off and it should track down the flag relatively quickly for us you can see I have my notification just display up here and that is What you wouldn't get just that simple nicety if you if you were running it with the docker instance and docker container So, okay, that is the very very simple basic options Again, you could supply these targets as an argument You can add them specifically if you wanted to with the target queue or target add you could monitor directories of that Let me show you that a target add again. Let's target Flag let me do that actually let's say Let's let's use a shell it's the exclamation point to get a shell. Let's say echo flag This is Caesar and then let's pipe that to Caesar Oh, can I not do that probably With a with a subshell on that. Oh We just specify an argument to Caesar. That's probably why Caesar 13. There we go. Okay. Sorry Now that that is set up. Let's go ahead and target add just this and then okay Caesar will automatically find that because it has support for those you might be wondering What are all these units and things that are actually running and how is this all happening and for that? I would point you towards the documentation Katana does have docs and documentation that comes with the repository It's not already built If you wanted to go view these you could either build them yourself would simply make HTML using Sphinx Or you can go check it out at CTF hot the Katana dot read the docs dot IO That is publicly available and that will explain everything that we have written thus far in our documentation initiative This may have holes this may have gaps But I'll tell you a little bit about what you're installing and why the necessary binary external dependencies How to go ahead and set this up? Etc etc and it'll get to what this repel is the interactive case that you're working with some other command line arguments you specify and How you can go ahead and even write your own units or add things or modify things and how it all works behind the scenes With the manager monitor unit and target classes if you want to know about these specific units You can go into each specific section and learn more about if I go into cryptography Here we have a couple of cryptography units that are available and why they work the way that they work So you could explore and read about them etc etc Okay I've talked a lot and I think that's all that I want to showcase because now we have Katana installed Set up worked with the Docker instance working with bare metal on our host using some notifications getting things in our clipboard Adding files adding targets monitoring directories etc I do want to showcase how you can actually do this with a simple CTF that's running with CTF D on the internet or even Pico CTF So I will do that in the next video, but that's it. Here it is. Here's Katana Again disclaimer. It might not be everything that you want it to be who knows I think it does a few things and it does some some cool things And the things that it does do how I hope it does well in a good way, but All right enough me talking. I'm running out. I'll see you guys in the next video
