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.
Now that I have started to collect metrics for my APC UPS systems, I built a Grafana dashboard similar to the dashboard I used for Network UPS Tools. Check out a previous post where I got these metrics set up and into Prometheus. ups_dashboard This dashboard is based on a public Grafana dashboard for the NUT exporter that I used previously. Fortunately most metrics from Network UPS Tools are also available here in the apcupsd exporter.
As of October 2024, Fedora 41 is available. Compared to the previous release, Fedora 40, there are not a large amount of changes that a desktop user will notice. This release includes the GNOME desktop version 47 with minor updates to the UI. This release will also continue to include the latest releases of KDE desktop environment as an alternative to GNOME desktop. Another addition is the Miracle Window Manager which is a tiling window manager based on the Mir compositor library.
I have previously worked with Postgres as a database. Check out a previous post if you are not familiar with Postgres. In that post I ran Postgres as a docker container and used psql to execute commands against the database. Today I am going to look at running Postgres with Podman as an alternative container engine and another container “adminer” which provides a web UI for interacting with a database. If you are not familiar with Podman, check out a previous post about alternatives to Docker.
APCUPSd, short for APC UPS daemon, is an open-source software suite designed to monitor APC (American Power Conversion) brand uninterruptible power supplies (UPS). APCUPSd allows continuous monitoring of APC UPS devices. It retrieves information such as battery status, load levels, input/output voltage, and other critical parameters from the UPS. I have looked at a similar software previously for my homelab systems. It was called Network UPS Tools (NUT). Check out a previous post to learn more about NUT and getting metrics from it.
Renovate is used to help manage code dependencies. Checkout a previous post for more details on what Renovate is. Renovate is able to parse dockerfiles to look for newer container images. This only works with either a sha256 digest or a version tag. Tags such as latest or some other arbitrary string will not work. I tested running renovate as a docker container. Credentials can be used with environment variables within the container.
PostgreSQL is a relational database management system. It is extremely popular as it is open source and scales to billions of rows. Other popular DBMS systems include some that are not open source. There are some open source apps that I use at home that require a database and I am interested in spending more time developing my own software. This post will go over the basics of using a PostgreSQL database.
