Programming Throwdown, Episode 29. Kuda and OpenCL. Take it away, Patrick.

So I'm a little under the weather.

So if I sound stuffy or terrible, I'm going to blame that.

Yeah, I dragged him kicking and screaming into the Programming Throwdown Studio to record this episode.

The studio, wait.

The studio?

Am I taking too much medicine?

Alright, so I do have an opening topic

and then uh maybe i'll lose my voice already and be quiet for the rest of the

episode hey stop cheering all right so i've i link a website here in the uh show notes

origami tessalations dot com but more specifically i my mom was in town to visit, and she likes doing puzzles or whatever.

I don't know how we got on it. My mom likes to do. Maybe it's a mom thing. It needs to connect with moms and puzzles. I mean, I think it's, I like puzzles as well. I just don't have patience for them. Maybe that's what it is. is a connection with like, like, you know, for example, like my parents are close to retirement.

My dad's already retired.

So they have plenty of time. what it is. It is a connection with like, like, you know, for example, like my parents are close

to retirement. My dad's already retired. So they have plenty of time that we don't have because

we're working kids, all that stuff. Yeah. So I think we could probably be puzzle masters in

40 years. And how many? 30 years, 40 years? 10. Early retirement.

Oh, really? That's a puzzle. If you can solve that puzzle, let me know. Yeah, yeah. I'll sell a book. Yeah, that's right. So anyway, so she was out to visit us, and we somehow, I don't remember, I think I had some origami paper I had found at a store or whatever. And I was like, oh, off and on throughout, you know, childhood, I had tried doing this amazing art of folding paper and never been very good at it. And recently I found some and tried it and decided I was going to search on YouTube. And surprisingly enough, YouTube is an excellent teacher for origami. Right. Sometimes. Now sometimes people do stuff.

They're like, oh, you just do this. And then they like put their hands in front of the paper house. They do some crazy trick, awesome voodoo stuff. And then it's just as puzzling. But for like straightforward things and for the most part, rather than looking at the diagram, you know, it's a really useful thing. So my mom and I started doing some origami in the evening as like something to do as opposed of just sitting and watching TV or whatever. And she was really, really excited about it and really excited to watch YouTube videos and see like, oh, this is really helpful. Like I never knew how to do this before or whatever. So we folded some animals and some complicated shapes and some simple shapes. It was a lot of fun. But this website, origami tessellations.com, I had come across probably a couple years ago. And the guy here, I believe his first name is Eric. I won't try to pronounce his last name. He does tessellation origami, which is just like you would think tessellation is like the same shape. Triangles? Triangles or squares. Oh, that's right. It shifted around. And of course, once you have triangles, you can do hexagons. And so it's basically you first fold the paper into pre-creasing it with like, let's say, a bunch of squares. Then you do a set of maneuvers, probably not using the right word,

anyways to fold those into something else or like also a repeated pattern or a new shape. And I just find it really interesting because normal origami is cool, but sometimes, you know,

it's like how many different ways can you fold a penguin? Well, they don't look that much like
