Toby Driscoll's personal blog at tobydriscoll.net covers math and programming. Since 2019, 7 different Hacker News readers have linked it 7 times, most often “Matlab vs. Julia vs. Python”. No feed was found, so read it on the site itself.
Too few sampled comments (3) to say how often HN recommends it.?
Why HN links it
HN readers link Toby Driscoll's numerical computing material, including an introduction to floating-point numbers, notes on differentiation matrices, and a comparison of Matlab, Julia and Python.
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.

Here's a great introduction to floating-point numbers: https://tobydriscoll.net/fnc-julia/intro/floating-point.html The next representable number after 9999999999999998.0 is 1.0e16. 9999999999999999.0 is not exactly representable in IEEE 754 floats, and will be rounded up or down. The difference between 0.0 and 2.0 in the table is likely due to different rounding modes. I'm curious how different languages end up wit…

HN discussionSomeone made a great comment about the matrix approach to teaching the derivative and deleted it, maybe because it wasn't rigorous. Seems like "Differentiation Matrices" is the technical term: https://tobydriscoll.net/fnc-julia/bvp/diffmats.html
