Neuralatex: A machine learning library written in pure LATEX (neuralatex.com)
Neuralatex is a scalar values-based auto-grad library similar to MicroGrad but written entirely in latex! As part of your latex document you can specify the architecture of a neural network and loss functions, how to generate or load training data, and specify training hyperparameters and experiments. When the document is compiled, the latex compiler will generate or load training data, train the network, run experiments and generate figures.

Understanding Automatic Differentiation in Jax: A Deep Dive (ispeakcode.substack.com)
Welcome to the world of JAX, where differentiation happens automatically, faster than a caffeine-fuelled coder at 3 a.m.! In this post, we’re going to delve into the concept of Automatic Differentiation (AD), a feature at the heart of JAX, and we’ll explore why it’s such a game changer for machine learning, scientific computing, and any other context where derivatives matter. The popularity of JAX has been increasing lately, thanks to the emerging field of scientific machine learning powered by differentiable programming.

Ask HN: Are my HPC professors right? Is Python worthless compared to C? (ycombinator.com)
I'm a PhD student implementing a finite element code. It simulates electromagnet waves passing through heterogeneous material. This code has to run in parallel, and run fast. I've been using old C libraries like PETSc to do this, and honestly, I do not enjoy working with C at all. Its esoteric and difficult to understand, and just overall feels like I'm using a tool from the 70s.
