What the Hacker News discussion says — and what it does not

Discussion focus

Across the sampled HN recommendations, people specifically point to Timestamps on reflection test, curvature combs, B-spline continuity. and Additional spline material from the same creator..

A recorded perspective

The recorded HN source is “Another upvote for Freya Holmér's amazing video "The Continuity of Splines".” — a useful perspective from AceJohnny2 in 2022-12, rather than a claim that every Hacker News reader agrees.

Evidence boundary

Alongside recommendations, the export retains a reference mention from zengid (2022-12): “which is a great line” This is context, not proof; use the linked discussion to inspect the original thread.
