Namedtuple in a Post-Dataclasses World
namedtuple has been around since forever, and over time, its convenience saw it used far outside its originally intended purpose. With dataclasses now covering part of those use cases, what should one use named tuples for? In this article, I address this question, and give a few examples from real code.

0x7FDE623822FC16E6: A magic constant for double float reciprocal (2011)
EDIT: I never expected this post to garner so much interest. Just to be clear, using the constant is a very bad idea in almost every situation I can think of. Even instructions like RCPSS should only be used by people who are convinced that the tradeoffs are worth it (or don’t have any other choice). Subtracting from…

Useful algorithms that are not optimized by Jax, PyTorch, or TensorFlow
In some previous blog posts we described in details how one can generalize automatic differentiation to give automatically stability enhancements and all sorts of other niceties by incorporating graph transformations into code generation. However, one of the things which we didn’t go into too much is the limitation of…

Julia's multiple dispatch explained with Pokemons
T hese days, I find myself evangelizing for Julia quite a bit. It’s a good language, especially for scientific computing, but I believe its focus on performance also makes it a good general language as well. At some level, programmers who know multiple languages have an abstract understanding of the constructs used…

Clojure builds as an amalgamation of orthogonal parts
The Clojure Core team recently released a new Clojure library, tools.build , that is a culmination of thought around batteries-included build support for Clojure projects. I won’t go into detail around the history and contents of the library in this post because much of that is found elsewhere, including the…

GPU Architecture Types Explained
The behavior of the graphics pipeline is practically standard across platforms and APIs, yet GPU vendors come up with unique solutions to accelerate it, the two major architecture types being tile-based and immediate-mode rendering GPUs. In this article we explore how they work, present their strengths/weaknesses, and…
