Random Errors

This site is a place where I document the solutions for the random problems and errors I encounter when writing code or learning new technologies. For most of the topics listed below, I created the article only after completing an extensive Internet search for a solution, but couldn't find one, before finally figuring it out myself. The site currently has 26 posts.

I added the Music Maker FeatherWing to a ESP32 Feather V2 device and I’m following the instructions in the tutorial to run the feather_player sample sketch. I put some music files on the memory card, inserted it in the memory card holder then changed the file names in the sketch so it plays the sound files I have on the memory card.

After sorting out how to deploy code to an ESP32 device that runs different code on each processor core, I set about building out my application. As soon as I added my project's code to one of the cores, the device started rebooting again when it ran the code and generated the following error message:

I built several projects on the ESP32 platform over the last few years; I recently published an update to my Glowing Pumpkin project. The project basically randomly flashes some LEDs with the intention that you put it inside a carved pumpkin and it does cool light effects inside the pumpkin. I wanted to build a version that used web application to control which color displays on the device so I set about learning how to run two processes on the processor, one that handles the LED stuff and the other that runs a web server accepting color requests from a remote device like a smartphone or tabled.

I was working on a Eleventy Plugin starter project yesterday and when I built the sample site and opened it in the browser, Chrome gave me a bunch of errors related to hosting site assets:

There is an error I see in Eleventy periodically when I'm either working in a new site or working (coding) a plugin. The problem occurs when I execute the eleventy command to generate the site. Here's the full error block:

I use a npm package I created called Eleventy-New-Post to create new posts for my Eleventy sites. It saves me the work of copying a post file in the project folder then emptying it before adding the new content for the post. It also automates selecting a category for the post from an automatically generated list of all categories used by the site.

While migrating my personal blog to Eleventy, I decided to add a statistics page to the site. As part of that, I wanted to add the publish dates for the first and last posts on the site. Getting the first post date was easy:

I've been trying to figure out how to easily build a categories page for this site that lists all categories including the number of posts per category (easily done in Eleventy) and a separate page for each category with pagination when the article list is greater than 20 posts.

I am in the process of migrating my existing johnwargo.com site hosted on FatCow to Eleventy hosted on Netlify and while I work on the site, I setup my jmw-test.com domain so it points to the work in progress site.

I recently switched this site to Eleventy and I noticed that my posts weren't sorting correctly on the home page. I want them sorted in reverse chronological order, but the site did the opposite.
