This is a personal blog focused on computer software and hardware. Most
projects are implementing software and hardware for a homelab. What is a
homelab? I would say a homelab could be a single computer or dozens of
computers connected in a network. You can also integrate with computers
in the Cloud.

Large language models are artificial intelligence systems that use complex algorithms to process and analyze vast amounts of text data, allowing them to learn patterns, relationships, and context within language. These models typically consist of multiple layers of interconnected neural networks that are trained on massive datasets of text, often exceeding tens or even hundreds of millions of examples. As the model processes and learns from this input, it develops an ability to generate coherent and natural-sounding text, respond to prompts and questions, and even engage in creative tasks like writing stories or composing music.

Caddy_logo I will be using Caddy to serve as a reverse proxy for my network. With Caddy, I can manage my proxy configurations in a single file. Caddy is an easy to configure web server and can also function as a reverse proxy. Caddy is free and open-source software.
On a system where I want to securely expose services running on containers, Caddy is easy for me to pick a certificate and then define all of the proxy rules for each container in a single file.

Renovate is an open-source tool that helps you automate dependency upgrades, vulnerability patching, and security compliance in your software projects. Dependencies can be software libraries like NPM packages for JavaScript or PyPi packages for Python or modules for Terraform or also container images from container registries. If you store your code and Infrastructure as Code in Git repositories, Renovate can help you keep all of your software up to date and open Pull requests automatically.

In a vain attempt to fix issues I am having on my Linux laptop, I wiped my drive and installed Fedora 40. I was using Debian 12 since it released but my laptop has issues related to the dedicated AMD GPU. Feel free to skip the summary of my issues as the rest of this post is about setting up Fedora 40.
Issues with Current system When I attempt to launch an application on the dedicated GPU with the environment variable DRI_PRIME=1, there are graphical artifacts and then the system becomes completely unresponsive until you hold the power button for a reboot.

gitea_logo Setting Up Gitea in a Docker Container and Securing it with Nginx Gitea is a lightweight, self-hosted Git service that can be easily deployed in a Docker container. In this post, we’ll go through the process of setting up Gitea in a Docker container and securing it with Nginx as a reverse proxy.
Prerequisites First, you need to install Docker on your server. If you are not familiar with Docker, check out a previous post to get started and install the required software.

Through 2024 I have been redesigning my homelab. Now that networking, firewalls, and servers are operational, the foundation is in place to start managing software projects within the Homelab.
Critical server software The most important software in use in my homelab is tied to the “critical” servers. “Critical” servers will run 24/7 so I opt for the lowest power usage devices that I own which in my case is 2 Raspberry Pi devices.
