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.

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.

A Network File System (NFS) server is a network protocol that allows a system to share its files and directories with other systems over a network. NFS is commonly used in *nix environments to enable file sharing between systems. A basic NFS server is easy to set up and you can choose what directory to share with other systems.
Ubuntu setup On Ubuntu, first you install the nfs server packages and then enable a system daemon to manage the server and client connections.

AdGuard Home is a network-wide software for blocking ads and tracking. When used as your network DNS server, you can also manage custom DNS records in your local network. Once configured as your DNS server, all devices on your network will have ads and trackers blocked.
DNS is a distributed naming system for translating domain names (like example.com) into IP addresses (such as 192.168.1.1) that computers understand.
DNS resolves human-readable domain names to machine-readable IP addresses, enabling users to access websites, send emails, and connect to other networked resources using memorable domain names rather than numeric IP addresses.
