Upgrading RHEL Using Leapp

Upgrading Red Hat Enterprise Linux has gotten a lot easier in recent years. While Fedora has been able to do in-place upgrades for decades, for unknown reasons, RHEL only recently gotten a supported way to do in-place upgrades. Before RHEL 8, it was rebuild and switch over.

Well, now, thanks to Leapp, you can upgrade RHEL in place. And while it’s not a simple or clean as using DNF in Fedora, it does work and pretty well too.


Getting Started With Raspberry Pi Pico on macOS

The modern Mac platform makes a great development environment for embedded programming. The Raspberry Pi is a very inexpensive, and even in 2023, relatively available embedded board. It’s very easy to interface it with other devices. And there are many language options. The Arduino, µPython, or the native C development tools all great options that work well on macOS.

The Arduino and µPython environment are simple and straight forward to get working.

The C development tools for the Raspberry Pi Pico work fairly well on macOS. However, it does take a bit to everything set up. It seems there are different sets of instructions, some work, some don’t works so well. I used a mixture of things and figured some stuff out myself So I provide what I did to get everything to work under macOS 13 on a Mac Studio with an M1 Max processor.

All 3 provide powerful tools to develop software for the Raspberry Pi Pico SBC.


Commodore 64 Files on macOS

C=64 Boot

Last year, I managed to acquire a C=64 Maxi. It’s a faithful replication of the original Commodore 64 based on an ARM SBC, similar to a Raspberry Pi, running a minimal Linux kernel and VICE. As I’m also a Mac user, I had to figure out how to access and transfer files, and develop software for the C=64 on the Mac. This should be mostly the same if using The C=64, or emulation of the C=64 on the Mac itself.


A Few Hugo Tips and Tricks

Hugo is a pretty powerful Web development tool. But everything isn’t always obvious. I’ve had to figure a few things out that could probably be documented a little better. So here are my notes on a few random things.


Remembering The Strange Events of the Summer of 1981 in Rural Ohio

Night Siege

After several years and trips to my parent’s house searching, I finally found my mother’s UFO books. She gave them to me upon her death. In with them, I found Night Siege: The Northern Ohio UFO-Creature Invasion by Dennis Pilichis.

It chronicles the strange events in the summer of ‘81 in rural Ohio. Reading it after all these years, brought back a lot of memories. It was a crazy time.


Moving From Wordpress to Static S3 Site

Using AWS s3 to host a web site is easy, and rather inexpensive. Also using S3, there is no code or database required, so not only is security better, but there is a lot less complexity than using Wordpress. If you have your own domain name, you can either use Nginx or Cloud Front with Route 53 to front end it. I chose the former as I didn’t want to give up control of my domain to AWS.

You’ll also need a static site generator, unless you want to write the HTML yourself. I started with Pelican, but switched to Hugo. Pelican just didn’t work the way I wanted it to. So far, except for a few minor issues, Hugo is working just fine.
