Divyansh Agrawal's personal blog at divagr.com covers ai, programming and science. Since 2026, 7 different Hacker News readers have linked it 7 times, most often “Qwenputer: A functioning, deterministic RISC-V CPU inside Qwen3.5”. It is still writing: the last post was on 2026-10-30, and you can follow it by feed.
Too few sampled comments (4) to say how often HN recommends it.?
Why HN links it
Commenters link the Qwenputer post, which describes a deterministic RISC-V CPU built inside Qwen3.5 weights. Other comments link the author's resume and Factorio simulator project. None judge the writing.
Summarised by Claude from a sample of 4 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
Research notes and experiments on machine learning systems, reinforcement learning, evaluations, and language models.

HN discussionA couple thoughts on the process here… First off, Opus 5.5 built working weights and code with only two prompts: 1. Read this article and any relevant source code: https://divagr.com/blog/qwenputer . Then explore if you could emulate the chip and ram in a Nintendo Entertainment System (as people do today with FPGAs in MISTRs) using this technique. If so, what size model would you have to build and if you could use s…
