Migrating from WordPress to Jekyll
Since launching this site in 2014, it has run on WordPress. I have always wanted to move the site to another blogging platform, especially since I wasn’t really taking advantage of all of the WordPress features.

Some Great Fish Shell Plugins
As a long-time Linux user, I am pretty comfortable with command line interfaces. However, as I started learning more about automation and how important it is to get your computer to do more work for you, I leaned toward wanting my command line shell to do more. Eventually I switched to fish shell, a very user-friendly shell with excellent scripting capabilities that is far more readable and less obscure than bash.

Typing Chinuk Wawa in Emacs
Back in 2015, I took a course in being an ally for local Native American communities from the Portland Underground Grad School (PUGS). One suggested action was learning the local language, but it proved difficult to find opportunities. When the pandemic forced school closures, though, Lane Community College began offering classes online. I found out about this thanks to the Kaltash Wawa blog, and this fall I signed up to take a remote Chinuk Wawa class through Lane Community College.

Recording Podcasts in Linux
I co-host a podcast called My Alchemical Bromance, and one of the frequent challenges I end up facing is how to record video and voice chats for interviews. A lot of podcasters use external hardware devices, such as the Focusrite Scarlett 2i4, which is a great solution. But I wanted to do it all in software—and in Linux.

Slides on a Stick with Raspberry Pi Zero W
If you give presentations often, you will know that one of the biggest headaches is managing slides. You have to figure out software, hardware, and connectors. I’ve usually resorted to bringing a USB thumb drive with my slides in PDF and ODP format, but then I came across an even better idea: the Raspberry Pi Zero W (or RPi0W).

Arduino Planetary Hours library
I am finally announcing my PlanetaryHours library for the Arduino. This library uses the
sun_rise()andsun_set()functions from the avr-libc time.h library to calculate planetary hours. -

Raspberry Pi GPIO with Erlang
Raspberry Pis are super cool. One of the neat things about them is that they have a ton of general purpose input/output (GPIO) pins, so you can use them to control all sorts of external devices. Unfortunately, most of the examples and applications are written in Python. I know, a lot of people really love Python, but it’s just not my cup of tea.
