Ramkumar Ramachandra's personal blog at artagnon.com covers programming and writing. Since 2010, 16 different Hacker News readers have linked it 41 times, most often “A tour of the LLVM back end”. It is still writing: the last post was on 2026-10-23, and you can follow it by feed.
Too few sampled comments (3) to say how often HN recommends it.?
Why HN links it
HN commenters link this blog's posts on proof assistants and theorem provers such as Lean and Coq, citing them as background for their own points. One bare link goes to a post comparing cities.
Summarised by Claude from a sample of 3 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?
I am still very new to proof theory. So please take this with a mountain of salt. At the core all these proof assistants, is a dependent total functional programming language. Total means all functions must be obviously be terminating. Dependent means types can dependent on values or more generally you can have quantifiers (sigma and pi). Both Coq and Lean have variants of a dependent type theory called “Calculus of…

HN discussionI've self-taught myself undergraduate-level Mathematics, and am currently enrolled in an advanced Masters program specialized in higher category theory at Université de Paris. Here are some thoughts: First, the amount I learnt on a day-to-day basis from self-studying in my free time pales in comparison to the amount I learnt from a structured course ending with an exam, in which you have to commit to studying 2~4 ho…

HN discussionOne place where the stash is really useful is pre-rebase. Unlike in merge, you need a clean worktree before you can rebase irrespective of whether or not those worktree changes will be affected by the rebase. A very common workflow on a topic branch: $ git stash $ git rebase master $ git stash pop To automate this workflow, there is a topic called rr/rebase-autostash that introduces the configuration variable rebase…

HN discussionI used to work as a compiler engineer in the US for several years, before deciding to try starting over at the age of 30, in pure mathematics. I moved from the US to Paris in pursuit of an affordable mathematics education, and spent two years in a Masters program. I did have a considerable amount of savings, but it was very risky nevertheless: if it didn't work out, I'd be out-of-touch with compilers, and it would b…

HN discussionLean is a great idea, especially the 4th version, a huge level up from the 3rd one, but its core still deficient[1] in some particular scenarious (see an interesting discussion[2] in the Rock (formerly Coq) issue tracker). Not sure if it might hinder the automation with the AI. [1] https://artagnon.com/logic/leancoq [2] https://github.com/rocq-prover/rocq/issues/10871
