Personal blog · andreinc.net · on HN as nomemoryprogrammingmath
Andrei N. Ciobanu's personal blog at andreinc.net covers programming and math. Since 2021, 28 different Hacker News readers have linked it 55 times, most often “Challenging software projects some programmers should try”. It is still writing: the last post was on 2026-10-29, and you can follow it by feed.
Too few sampled comments (9) to say how often HN recommends it.?
Why HN links it
HN readers link Andrei N. Ciobanu's posts as explainers and references on math and programming, including an animated Fourier series introduction, the Shunting-yard algorithm, small virtual machines, and project ideas.
Summarised by Claude from a sample of 9 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
A minimalist developer blog.
