Murage Kibicho writes LeetArxiv, a personal blog at leetarxiv.substack.com about programming and math. Since 2025, 11 different Hacker News readers have linked it 58 times, most often “How GCC Eliminates Unnecessary Integer Division”. It is still writing: the last post was on 2026-09-28, and you can follow it by feed.
Too few sampled comments (2) to say how often HN recommends it.?
Why HN links it
The linked posts cover solving problems with mathematical and computational methods, such as a Sinkhorn-based sudoku solver and SAT solving. One comment reports a broken link to the sudoku post.
Summarised by Claude from a sample of 2 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

I run a Substack where I show programmers how to turn advanced math papers into C and Python code. I'm a math guy who codes and I do it for fun. I'm shocked people are interested in this stuff. LeetArxiv Substack: https://leetarxiv.substack.com/

HN discussionSuper silly but I'm searching for a mathematical backdoor in Bitcoin's secp and the secr curve. I saw that both curves use unsafe primes (p-1 factors pretty well) for the generator order. So I'm trying to define a multiplication operation using primitive roots.

HN discussionShameless plug. I run LeetArxiv. It's a successor to papers with code built on the thesis "Every research paper should be a brief blog post with relevant code".

HN discussionOther paper implementations have code. I realized the papers I implement using long-form latex math examples tend to do better. So my pure coding implementation of Blankinship's algorithm : https://leetarxiv.substack.com/p/paper-implementation-blanki... Performed much worse than my written implementations.
