I'm no fan of inheritance either, but I'm not sure it's that cut-and-dry. As a rust example, it's not uncommon to see struct Horse {...} enum Quadruped { Horse(Horse), ... }; possibly al

I wish English[1] had a word to describe the enjoyment felt from using a well-designed tool like this. "Ergonomic" comes close, but I think it's a little too utilitarian - it doesn't quite capture the "this is nice&

It's by no means rigorous, but the gist of it is that 1. You're integrating the polynomial that best approximates the function over the interval. This is why quadrature is exact for polynomials up to some order: the best approxi

Polynomials, sampling theory, signal processing, Fourier series, etc. are all so closely related that learning even a little bit of one of these things opens up such a wealth of other things to think about and explore. Splines like this bas

Do the physicist thing and just define all your constants to be one. "How long is a day? 1 day." "I slept for .37 days." This nicely unifies things with the tao manifesto[1] people since 1 day = 1 turn = 1 tau = 2 * pi r

Yeah, I had a similar head-tilt at leading with "How are you doing on a personal level?" I'm not outright opposed to the question -- managers are human (gasp) and it is true that we tend to work better with humans when we c

Similar story - a PI had written some code to from (row, column) indices of the upper triangle of a matrix (made somewhat tricky by excluding the main diagonal) to a linear index. He used a for loop to start from the beginning and count up

> This gets to the why perfectly. Respectfully disagree. A matrix has basically nothing to do with "living on the surface of a cuboid". It's like saying FOIL is the "why" of binomial multiplication -- the "w

I agree, and I think this reeks of the Monad Burrito Tutorial Fallacy[1]. Once you know what the manipulations are you can start to visualize doing them in these weird 3d ways, but the understanding came through the struggle to make a c

I had a lot of fun working with the maintainers of this utility to better support Gaussian units[1]. This is usually done (incorrectly) by multiplying, say, some number of SI coulombs by a dimensionless constant (actually 2_997_924_580) to

Interesting philosophical question: is awesomeness intrinsic or extrinsic (a matter of perception)? Can anything be intrinsic? If it's intrinsic, then yes, the probability that it is awesome should not be zero if you've never he

I think this analysis is great and I like it a lot, but it's not quite what I was going for. Here, the size of a cell works against an independent measurement of length like "one meter". But, at a much more fundamental level,

I've done a lot of philosophizing on the nature of units and there's a bit of an interesting wriggle there. Most people think "length" and "time" are different things, such that 1m + 1s = garbage. Mathy physi

I did not make the original claim, that more rules stifles progress. Please show me the experiments done to demonstrate this or the logic used in deducing it and I will attempt to devise a counterexample.
