Graphics livecoding in Common Lisp (kevingal.com)
Some Lisps, like Common Lisp, have a powerful feature that tends to go underappreciated amidst all the talk about macros: the ability to recompile your program while it's running, without restarting it.

Cl-Yasboi: Yet Another Starter Boilerplate for Common Lisp (github.com/sebastiancarlos)
cl-yasboi (pronounced Yas boi!) is a modern (so 2025), minimalist, opinionated, and flamboyant Common Lisp starter project. It's designed to be a source of inspiration and a starting point for your own projects.

Redis from Scratch, or Cledis (jagg.github.io)
This week I was looking for something new, and I realised that I’ve never tried to do any network programming using Common Lisp. Also, some time ago I came across the Build your own Redis book, but never tried to go through it. The project is perfect, it contains threading, networking, and even some async programming. I had no idea what the Common Lisp ecosystem for those things looks like, so it was time to find out.

Depending in Common Lisp – Using the CLOS dependent maintenance protocol (2022) (stevelosh.com)
A while ago I was working on a Common Lisp library that makes use of the Metaobject Protocol. I ran into a few edge cases around dependencies between classes and it took a while for me to figure out how to solve them, so I wanted to write down what I learned in case anyone else might find it useful. This post is an expanded version of a Reddit thread I posted.

Why I Chose Common Lisp (djhaskin.com)
After ~7 years, I was done with Clojure. I was writing a some CLI apps, and I hated how long they took to start up. The community at large seemed not to care about this problem, except for the babashka folks. However, I spent long, hard hours banging my head against native-image and it just wasn't working out. It was incredibly painful, and at the end of it, I still didn't have standalone, fast-starting native executables.

A Closed and Common Lisp (2021) (flooey.org)
I just recently finished up Advent of Code for 2021, and, like last year, I did it in a new-to-me language. This year’s choice was Common Lisp. My total previous exposure to Lisp was a couple weeks writing Scheme in my Programming Languages class at university, so it was almost entirely a novel experience.

OCRing Music from YouTube with Common Lisp (nickfa.ro)
There's a tune on YouTube I always really liked called "Supersquatting." It was written by Dubmood and Zabutom, two really masterful chiptune composers, but this track always stood out to me as sounding really full and "fat."

The Long, Painful History of Time (1999) (naggum.no)
The programming language Common Lisp offers a few functions to support the concept of time as humans experience it, including GET-UNIVERSAL-TIME, ENCODE-UNIVERSAL-TIME, DECODE-UNIVERSAL-TIME, and GET-DECODED-TIME. These functions assume the existence of a timezone and a daylight saving time regime, such that they can support the usual expression of time in the environment in which a small number of real-life applications run.

AP5 - Declarative Programming Library For Common Lisp (1995) (oceanpark.com)
This is a ruthlessly abridged presentation of AP5, a high level language, currently implemented as an extension to Common Lisp. I write this to communicate my discovery of a good language to others. Everything described is implemented.
