Why not: from Common Lisp to Julia

This article is a response to mfiano’s From Common Lisp to Julia which might also convey some developments happening in Common Lisp. I do not intend to suggest that someone coming from a Matlab, R, or Python background should pickup Common Lisp. Julia is a reasonably good language when compared to what it intends to replace. You should pickup Common Lisp only if you are interested in programming in general, not limited to scientific computing, and envision yourself writing code for the rest of your life. It will expand your mind to what is possible, and that goes beyond the macro system. Along the same lines though, you should also pickup C, Haskell, Forth, and perhaps a few other languages that have some noteworthy things to teach, and that I too have been to lazy to learn.

/I also do not intend to offend anyone. I’m okay with criticizing Common Lisp (I myself have done it below!), but I want t

How to uninstall guix

Date of creation: 2022-12-27

First of all, if the install script referenced here was used to install guix, ideally the output of that script as well as the script itself should have been saved somewhere. This makes it easier to see which components were installed and where and thus makes it easier for you to uninstall them.

As for me personally, I used the install script to install guix on a debian derivative distribution with systemd. This guide thus focuses on uninstalling guix from a debian derivative distribution but will probably work for your distribution as well with some slight changes.

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.
