A harsh popping sound at the start and end of audio playback in Linux was driving me crazy. This is on a Dell XPS13 laptop and the issue is the power saving subsystem. Here's how to resolve the issue using Pipewire (Wireplumber) on Arch Linux.
Hyprland has no built-in support for conditional configuration. This makes me a bit sad as I like to maintain a single dotfile repo that works for more than one computer. Here's how I configure Hyprland based on hostname.
Zephyr includes a test runner app called Twister. It has a dizzying number of features, and recently I wrote a script to configure the tool for my most-used operation: cycle testing on embedded devices.
A few weeks ago I made the switch from using Conquery of Code (CoC) to using Neovim's native Language Server Protocol (LSP). This modernized my vim setup and delivered the kind of hinting, linting, and completion necessary to code efficiently.
My Linux configuration files–colloquially known as dotfiles–are now publicily available. This post shares some interesting Git commands I learned when creating the repo.
The TTGO T-Display is an ESP32 development board from Lilygo with an integrated screen that looks fantastic. While this has great support with Arduino and (I assume) ESP-IDF, it took a bit of playing around with a Devicetree overlay file to get the screen working in Zephyr.
It's impossible to buy a Raspberry Pi right now so my company is looking to the Orange Pi as an alternative. One perk is that these boards include eMMC memory so that the OS is stored on the board itself. Here's how to install Linux to the flash memory.
One of my Vim plugins generates a .cache directory in every project. Instead of telling every git repo to ignore it, use the system-wide exclude file.
Finally, I figured out how to make my system stable. For about a year I had been experiencing random freezes on my new system — but not ever while using it. I would come back in the morning and try to wake up the machine and it would be frozen. Turns out the root cause is the C6 power saving states in the Ryzen core are not fully compatible with the Linux kernel. Grrrr!
I upgraded from a Chromebook to the Dell XP 13 (9360). The Developer Edition comes with Ubuntu 16.04 Xenial preinstall — which I love because it means this machine is counted as a Linux laptop and not as a Windows machine. After installing the Cinnamon Desktop and doing a dist-upgrade the screen resolution settings were lacking. I could only choose 1920×1080 and 1360×768 as my 16:9 options. The…
