Swift Numerics
I’m excited to announce a new open-source project for the Swift ecosystem, Swift Numerics! Swift Numerics will provide the building blocks of numerical computing in Swift, as a set of fine-grained modules bundled together into a single Swift package. My hope is that we can quickly fill some important gaps in the…

Twitter, but for Math, with Toots
Hooray, it’s yet another social network for you to join! I’m skeptical about new social media, but I’ve been seeing enough posts about mathstodon.xyz that I finally caved and got an account. Mathstodon is the math(s) “instance” of mastodon , a new open-source, decentralized microblogging social network. It’s a lot…

Emulating double precision on the GPU to render large worlds
One of the problems with developing games with large game worlds is that objects start to jitter and teleport around as you move away from the world origin. This post is about how we overcame one challenge in particular and what we did.

The algebra and calculus of algebraic data types
Just as algebra is fundamental to the whole of mathematics, algebraic data types (ADTs) are fundamental to many common functional programming languages. They’re the primitives upon which all of our richer data structures are built, including everything from sets, maps, and queues, to bloom filters and neural networks .

Thoughts On Machine Learning Accuracy
This blog shares some brief thoughts on machine learning accuracy and bias. Let’s start with some comments about a recent ACLU blog in which they ran a facial recognition trial. Using Rekognition, the ACLU built a face database using 25,000 publicly available arrest photos and then performed facial similarity searches…
