Math, Numerics, and Software is a personal blog at reidatcheson.com about math, programming and science. Since 2019, 3 different Hacker News readers have linked it 3 times. It is still writing: the last post was on 2026-09-12, and you can follow it by feed.
Too few sampled comments (1) to say how often HN recommends it.?
Why HN links it
HN readers linked a post on optimizing the training loop of a tiny transformer by inlining it into C++ with CUDA graphs instead of using PyTorch. The one comment does not judge the writing.
Summarised by Claude from a sample of 1 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?
I have no submission for this but I joined the hype in my own way by optimizing the training loop. These tiny models are not really well suited to frameworks like pytorch, and with highly patient AI agents we can now just inline the whole thing into C++ just to see what happens, which I do below: https://www.reidatcheson.com/transformer/llm/ml/cuda%20graph...
