quantblog is a personal blog at quantblog.wordpress.com about math and programming. Since 2009, 5 different Hacker News readers have linked it 18 times, most often “Homeschooling as a right, and a needed practical alternative”. It is still writing: the last post was on 2025-10-30, and you can follow it by feed.
Too few sampled comments (2) to say how often HN recommends it.?
Why HN links it
HN readers link this blog's posts on the math of JavaScript animations, such as rotating circles built from sine functions. One comment cites it as an example of teaching the sine function through code.
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.

What Hacker News says?
> What can startups do to increase prosperity for everyone? I agree with the fundamental dogma that startups are the best way we know to create good technology, which in turn benefits everyone. ie. the big wealth creators are discovering new resources and creating better technology. ( The big new resources are in space, or perhaps deep sea, so your back to startups to get there.) Extrapolating, it seems reasonable t…

HN discussionI feel the same frustration, seen from another angle : I think we can use current ML techniques to solve 3 or 4 hard problems in 3D reconstruction, and doing so would unlock a vast amount of value - we could turn lidar scans and photos of buildings and industrial plants into accurate 3D models automatically. BUT I think the bottleneck is _funding_ of small early risky startups to do the needed engineering work. My n…

HN discussionI think we should find a way to take the best content from Math Circles and get that to far more students in a digestible format. Drilling down even further, if the Question is "what is the _single_ most useful thing that can be done to increase future scientific literacy and accelerate technological progress ?" .. then I think the answer must be to teach multiplication by drawing rectangles. vis : https://quantblog…

HN discussionI propose 'gords rule' : "any sufficiently advanced LLM will learn the laws of logic, the principles of scientific method, and Reinforcement Learning" until that happens .. I think RL startups focused on real problems are much undervalued : https://quantblog.wordpress.com/2024/10/11/llm-hype-means-th...

HN discussionMy take, after working on some algos to detect geometry from pointclouds, is that its solvable with current ML techniques, but we lack early stage VC funding for startups working on this : https://quantblog.wordpress.com/2025/10/29/digital-twins-the... I have no doubt FeiFei and her well funded team will make rapid progress.

HN discussionWould be interested in peoples thoughts on what realistic read/write pressure is a good level to test at, to feel confident in real-world performance... [ if not HN level dos'ing ] Did a basic test of our new new thing, seemed to hum along okay at 10 w/sec and ~50 reads/sec - short writeup here : https://quantblog.wordpress.com/2022/06/26/mon-pho-aka-how-f...

HN discussion>You provided anecdata, so I used anecdata. Homeschooling is exclusively American because American schools are almost completely shit like most government provided services here and saying because German schools are good, American kids shouldn't homeschool is ignoring all the data that says US public schools are in trouble, on a steep decline and home schooling has for many, become their only viable alternative. Loo…

on “Ask HN: Freelancer? Seeking freelancer? (February 2015)”I had a great session with my 12yo getting an animated ball bouncing around a box, programming it in javascript using the canvas api [ ~120 lines ]. He got collision detection working with some help. I have tried myself, with very limited success, to make some engaging and educational software. I see a lot of edu software as mind-candy - strong on visuals/action but weak on concepts.. but I admit I haven't found the…
