Hologrammata is a personal blog at rantonels.github.io about science and programming. Since 2015, 7 different Hacker News readers have linked it 7 times, most often “Raytracing a Black Hole”. The last post was in 2018, but the archive is still widely read.
Too few sampled comments (3) to say how often HN recommends it.?
Why HN links it
Linked for a personal blog by a physics-minded author, covering black hole ray tracing and an exposition of entropic gravity from a string theorist's perspective. One commenter calls it their favourite treatment of the topic.
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.

HN discussionThat statement is indeed a bit vague. Let me elaborate: In the process of deriving the said equations, an equation for the radial coordinate of the photon was achieved. This was identified with a classical, Newtonian system of one particle with unity mass. As the real, massless photon lives in four-dimensional spacetime and the said massive "test particle" lives in three-dimensional space, these systems just can't b…
