Nix / NixOS misconceptions

Sunday, Aug 6, 2023

I’ve been using Nix for a year now. It’s been going fairly well, by the way. Here are some misconceptions I’ve had to overcome to become a more productive Nixer. False: You can’t deploy Nix software to Docker or Kubernetes False. If you can push to a docker registry such as docker.io, you can deploy to Docker or Kubernetes using Nix. You can use dockerTools.buildImage to build a docker image from Nix.

My first game jam

Thursday, Jun 8, 2023

Source lives here. Play it here. In a joint effort, Aliasing and myself have created a novel top-down action rogue-lite for the 2023 Spring Lisp Game Jam. Aliasing is an experienced game dev so in a way, I was along for the ride. Still, I managed to contribute some game mechanics, features, unit testing, CI/CD that deploys to super-rogue.workinprogress.top on every commit. This was a fun devops exercise for me - Aliasing mentioned to me that I helped keep him on track with the addition of automated testing and per-commit deploys to a website (it makes it easy to play-test pull requests).

Sillypaste migrated to fly.io

Thursday, May 18, 2023

I’ve been operating Sillypaste (source code) - a simple Django pastebin created for dogfooding. In this post I hope to capture some of the painpoints of working with Django, Python, Heroku, and the migration to fly.io. Ever since Heroku sold its soul to SalesForce its been on the decline. Customer service is worse than ever, giving wonderful canned responses to most questions. It used to be free to host Sillypaste on heroku, now is a $17/mo ordeal.

Can 4GiB meet your needs in 2023?

Monday, Feb 6, 2023

Figure 1: your computer on low memory TL;DR: yes. You can throw more swap at most processes and it’ll eventually finish… Eventually. Last year I warranty-ed a Dell XPS 13 with 32 GiB of RAM, all specced out. Sidenote: I wouldn’t recommend the Dell XPS 13, at least in 4K. The laptop gets anywhere from 1-3 hours of real world usage and gets hot as most Macbooks. The Dell XPS 13 4K is not a viable product.

#lang tinybasic

Wednesday, Jul 27, 2022

For the Lang Party Summer 2022, I wrote a BASIC interpreter. It took a bit of mental gymnastics and learning on my part. In this post I hope to share some of the experience in implementing this interpreter. For the curious, the code lives on GitHub. Figure 1: A TinyBASIC session in Cool Retro Term Try it out! Want to try it out? Run raco pkg install --auto tinybasic to install it.

NixOS Migration

Wednesday, Jun 8, 2022

Recently I have begun migrating my workstation and laptop from Gentoo to NixOS. There are a great deal of tradeoffs between the two operating systems. Before going into the details, consider where I’m coming from and why I moved away from Gentoo below. Why was I running Gentoo on workstations?? This is my heuristic for a good operating system: The Distro must provide facility to modify system packages and maintain their modifications in sync with the upstream distro.

Auto-rip Music CDs

Monday, Feb 7, 2022

Awhile back I found a stack of audio CDs I wished to digitize. It’s a bit of work to do the following steps quickly and while doing other more cerebral work: Open the disc tray Insert the disc Wait a few seconds for the disc to be detected by the OS Kick off abcde to rip the CD. Repeat ad infinitum. The solution is to streamline the workflow:
