What is a collision?
From Mario bouncing off a Goomba to two cars bumping into each other in a racing
game, dealing with collisions is such an integral part of most video games that
we often take it for granted.

Alright, let me introduce myself on this platform. I'm Kai. I really like programming. Here's a list of projects I've done:
A highly interactive blog post about 2D collision resolution in video games. I hope to finish part 2 this year, but no promises 🙈

I hate it when people say that. Because if you follow this thought to its logical conclusion, there should only ever be exactly *one* explanation about any topic.
This is obviously absurd. Imagine the only way to learn maths was by reading Wikipedia 🙃

“But Sam, there’s already content about how prompt caching works. Why bother?”
There is, and I’ve consumed lots of it. To write in this space I’ve had to learn about it, and I’m going to keep learning but also produce content along the way.

Won a volleyball tournament yesterday and now I'm walking around the house like I'm 80 years old. Played a total of 15 sets over 10 hours. Felt like my body was gonna break apart during the finals 😂 Super worth it though!

I received a letter from my insurance today informing me that they will increase my premium next year because I now fall in the "36-40 age range".

I recently started playing Clair Obscur: Expedition 33 and holy shit. I don't use this term lightly, but this game is *art*! The opening sequence genuinely made me tear up. And don't even get me started on the OST

I've been lifting weights pretty consistently for about 7 months. Yesterday, one of my volleyball teammates randomly came up to me and asked me if my arms have always been this muscular.
I'll be riding that high for the next year or two.

I think I might make another YouTube video soon. I've started creating these visualizations for myself because I'm bad at doing projective geometry in my head and I think it's actually a really cool topic.
(it may not look like it yet, but this is actually about the cross product)

Still super proud of this video I made 2 years ago. Views have kinda flat-lined so I'm posting it again because dammit I want people to see it!
