Given a dataset, which may be a scalar or an array, I am wondering what the generic syntax is to get its *contents*, so that they remain valid after the...

least squares implementation

AFAICT the [implementation](https://github.com/JuliaStats/MultivariateStats.jl/blob/master/src/lreg.jl) of linear regression forms the `X'X` matrix then calculates `(X'X)⁻¹(X'y)` using Cholesky factorization. I am curious why this was chosen. The the best of my knowledge, orthogonal...

Eg if ```toml baseURL = "my.site/dir" ``` then `.RelPermalink` of the root will be `dir`, so the condition [here](https://github.com/mismith0227/hugo_theme_pickles/blob/d12aafb104cca1cc4614875842968ea1c59f5173/layouts/partials/head.html#L54) is never true. Replacing that line with ``` {{ if eq...

RFC: storing intermediate values

Sometimes I solve nonlinear systems of the form ```julia f(g(x)) ≈ 0 # could be a scalar or a vector ``` where `g(x)` is a large, costly, and ultimately interesting...
