sb-simd: Multiplying a 4x4 matrix with a 4-length vector (AVX)

I'm assuming you are referring to the following operation:

Opinionated Common Lisp Resources 2020

If programming is more than just a means of getting things done for you, then Common Lisp is for you!

The ReadLine Wrapper (rlwrap) utility is actually a must have when you want to run SBCL from the command line, because by default, SBCL in the terminal:

• doesn't offer symbol completion
• doesn't offer a history of commands
• doesn't even understand the arrow keys, left and right (they input [[[A instead), nor any default readline keybindings, the ones we find in bash et all: C-e, C-a, C-u, C-k, Alt-b, Alt-f etc.

We can actually fix this with rlwrap options.

Features of a Common Lispy approach to (better) Numpy

Numpy is great, in fact it’s one of the things that pulls people to Python. But can it be better?

Common Lisp is great, in fact it’s one of the things that pulls people to Common Lisp. But can it be better? Indeed Python can’t be better than Common Lisp without it becoming another Lisp. The closest we have is Julia. And while it gets some things right, Julia lacks certain features that limit the goodness of a numerical computing library.

All combined, below I will highlight some of the features that I wish a numerical computing library or ecosystem had. I also want to request the readers for their own inputs about how things can be even better. The goal amidst this is solely to keep things numpy-like. I do not intend to - nor have the background to - make a DSL like April or Petalisp.

While I take some interest in performance and numerical computing, I have m
