Reproducable, flashable, updateable Raspberry Pi Images with NixOS

Fri, 16 Jan 2026 07:30:00 -0600

A lot of my knowledge laid out here would not be possible without the insight from Nixcademy and their blog series on NixOS images. Please check out the linked blog for more information on this topic. The code in this article is heavily inspired by or reused from that post.

I hope to add a little more to this topic by showing how to achieve a UEFI-based image for a Raspberry Pi. I also want to practice my technical writing skills for this article.

Automating Your Resume with Github

Sat, 24 Apr 2021 01:20:00 -0600

Background

Making your resume easily available and up to date can be quite the task. The approach I have taken is to host my resume on Github. Github has tools that make it easy to have links that always point to the latest version of a file, which is what we need for my approach.

What this approach uses:

A repository for hosting the resume LaTeX code.
Github actions for building the resume.
Git tags to tell Github when to build and “release” the resume PDF.

The final result of this process is something that, when set up, can be operated completely from the Git command line. All you have to do is commit changes to your resume repository, then create a tag when the resume is in a presentable state. A link can be put on your website that always points to the latest PDF.

Setting up External Monitor Brightness Controls on Arch Linux

This will be the first technical post on my website. I will use this post to describe the process in setting up external brightness control in Sway on Arch Linux.

Background

Kernel 5.9 added improved I2C support to Navi 10 cards¹, which include the Radeon RX 5600XT. Using I2C in combination with ddcutil can allow us to control an external monitors brightness using commands.

Using ddcutil

Detecting Monitors

First we need to make sure that the i2c-dev module is loaded into the system; In my case, it was loaded automatically. We now want to identify the monitors:
