Why It’s Great

  • Incredibly fast
  • Respects .gitignore files automatically
  • Smart defaults (recursive search, sensible output)
  • Integrates with VS Code, Helix, and Neovim

2. fzf—Fuzzy Finder for Everything

fzf is a fuzzy finder for the command-line. The longer you use it, the more you wonder how you lived without it.

What It Can Do

  • Fuzzy-search file names
  • Fuzzy-search command history
  • Fuzzy-search running processes
  • Create interactive pickers for your own scripts

3. bat—The Better cat

cat is fine, but bat is better. It’s a drop-in replacement that adds modern features without changing your workflow.

Features

  • Syntax highlighting
  • Git integration
  • Line numbers
  • Automatic paging with less

Bonus: Works beautifully with ripgrep and fzf for a hyper-efficient terminal workflow.

4. eza—Modern Replacement for ls

ls gets the job done, but eza (formerly exa) gives you a more readable view of your file system.

What You Get

  • Colorized output
  • Tree views
  • Git status indicators
  • Optional file icons
  • Better sorting options

Why You’ll Love It

Directory browsing will feel fun.

5. fastfetch—System Info With Style

Fastfetch is the spiritual successor to Neofetch—rewritten for performance, aesthetics, and modern systems.

Highlights

  • Extremely fast (written in C)
  • Beautiful ASCII logos
  • Highly configurable
  • Works on nearly all distros

Perfect For: Showing off your Linux setup.

Honorable Mentions

The Linux command line isn’t just a place to type commands—it’s a launchpad for automation, efficiency, and mastery. These five tools make Linux faster, more powerful, and more enjoyable in 2025.

Why NixOS Is the Most Important Linux Distro You Haven’t Mastered Yet

[![NixOS Icon](/wp-content/uploads/2025/11/NixOS-Icon-02.png){.alignleft}](/wp-content/uploads/2025/11/NixOS-Icon-02.png)

For years, Linux enthusiasts, **including myself**, have chased the “perfect distro.” Some want stability. Some want bleeding-edge packages. Some want reproducibility. And some—let’s be honest—just want something cool to tinker with at 2 a.m.

But **NixOS** quietly sidesteps this entire debate. It doesn’t compete with Ubuntu, Fedora, or Arch in the traditional sense. Instead, it **redefines what a Linux distribution can be**. We warned, **NixOS does have a steep learning curve**, but if you haven’t tried it, you’re missing one of the most transformative distros in modern computing.

## A Paradigm Shift, Not a Distro Hop

Most distributions configure the system through a web of package managers, shell scripts, and config files. NixOS ignores all of that and says: *”What if your entire system was a single, declarative, version-controlled document?”*

With NixOS, your system _is_ code. Not metaphorically, but literally. One file (*configuration.nix*, or a *flake*) describes:

– Installed software
– System services
– Users and groups
– Networking
– Hardware support
– Desktop environment
– Custom system tweaks

Change the file → rebuild the system → done.
If you can manage a Git repo, you can manage your entire OS.

## Reproducibility: The Superpower Other Distros Wish They Had

Imagine the following scenario: You set up the perfect workstation, terminal tools, development environments, fonts, and drivers. Then your SSD dies. Typically, you’d spend hours reinstalling.

On NixOS: **Git clone → nixos-rebuild switch → your entire system is back.**
Not just installed packages—the **entire configured system**, down to the kernel modules and systemd services.

## Below are some reasons why NixOS has a cult following among:
– DevOps engineers
– Software developers
– Homelabbers
– HPC folks
– Tinkerers and power users

### The Nix Package Manager

Nix, the package manager behind NixOS, is a beast—beautiful, powerful, and occasionally intimidating.

Here’s why it matters:
#### 1. Atomic upgrades

If an update breaks something, you can roll back your entire system in seconds.
#### 2. Zero dependency hell

Packages are built in isolated environments, so no more:

– Library conflicts
– Version clashes
– ABI breakage
– “This requires Python 3.12, but your system is on 3.11.”

#### 3. Multiple versions of the same software

Need Python 3.10 **and** Python 3.12?
Need two versions of Node?
Want three versions of GCC?

*No problem with Nix.* This flexibility makes NixOS feel like Linux in cheat mode.

## Home Manager: Your Dotfiles, Evolved

If NixOS handles system configuration, **Home Manager** handles user-level configuration—dotfiles, packages, shells, editors, theming, and more.

Home Manager lets you:

– Version-control your dotfiles
– Reproduce them on any machine
– Avoid “dotfile drift” across systems
– Switch between laptops/workstations effortlessly

Example:

home.username = {
programs.zsh.enable = true;
programs.starship.enable = true;
home.packages = [ pkgs.fastfetch pkgs.bat pkgs.exa ];
};

Rebuild → your environment is instantly standardized.

##### Home Manager is so good that even non-NixOS users install it. But on NixOS? It’s a match made in config-management heaven.

## Flakes: The Future of NixOS (and Why You Should Care)

Flakes add:

– Inputs (like package sources)
– Outputs (like your system config)
– Pinning (so updates never surprise you)
– Reproducibility across machines

Example:

nixosConfigurations.nixos = {   system = “x86_64-linux”;   modules = [ ./configuration.nix ]; };

Flakes lets you share your system between machines, maintain multiple configurations, and track changes.

## Why NixOS Feels Like Magic for Power Users

You’ll love NixOS if any of these statements hit home:

– “I want my whole system in Git.”
– “I want to rebuild a machine in 10 minutes.”
– “I’m tired of fixing dependency issues.”
– “I want the same environment on every machine.”
– “I want to understand _exactly_ how my system is built.”

NixOS gives you **control without chaos**, **flexibility without breakage**, and **power without fragility**.

## The Learning Curve: Real but Worth It

NixOS isn’t plug-and-play like **Pop!OS** or **Linux Mint**.

You will have to:

– Read docs
– Learn the Nix language
– Debug your configuration, and
– Occasionally mutter “Why isn’t this service starting?”

But once you get past the initial bump, something flips in your brain. You realize: *”This isn’t just a distro, but a better way to run computers.”*

## So, why haven’t you mastered it yet?

Not because it’s too hard—because it’s too _different_.

It asks you to let go of the old way of managing Linux.

But if you’re a Linux enthusiast, a sysadmin, or anyone who wants a smarter, reproducible, future-proof workflow, then NixOS isn’t just worth learning—it’s essential.

## Final Thoughts

I believe **NixOS** is the most important distro you haven’t mastered yet because it represents the next evolution of Linux use. Declarative systems, reproducibility, atomic upgrades, isolated builds, multiple versions, and Git-managed everything.

NixOS doesn’t just add features; it solves problems other distros have lived with for decades.

If you want a Linux environment that’s efficient, elegant, and engineered for power users, it’s time to give NixOS the attention it deserves.

And as always—welcome to the Saloon. Pull up a stool, grab a coffee, and let’s build your next great Linux system together!

Repurposing Older PCs as OPAC Stations with Debian Linux and OpenKiosk

Lenovo Tiny PC

In many libraries, aging desktop computers end up gathering dust or are sent to the recycling bin. At the Westhampton Free Library, I saw an opportunity to give these machines a second life by turning them into dedicated OPAC (Online Public Access Catalog) stations. By combining Debian Linux, the OpenKiosk Web Browser, and Innovative’s Vega Discovery catalog, we created a secure, efficient, and cost-effective solution that benefits both patrons and staff.

Why Choose Debian Linux?

Debian Linuix Logo

When evaluating Linux distributions, I tested several options, including Ubuntu, Fedora, and even NixOS. While each has strengths, Debian quickly stood out for this project. Debian’s lightweight desktop environments, such as XFCE and LXDE, run smoothly on older hardware with limited memory and processing power. Unlike some distributions that bundle in numerous pre-installed packages and background services, Debian provides a clean, minimal installation. This helps reduce system overhead and speeds up boot times.

Another advantage is Debian’s reputation for long-term stability and predictable updates. Once configured, the systems require very little maintenance beyond regular security updates. This was important, since I don’t want to spend a lot of time constantly tweaking settings or troubleshooting software conflicts. Additionally, Debian’s robust documentation and active community support made it easier to find solutions to help customize the environment.

What is OpenKiosk?

OpenKiosk Browser Homepage

I installed OpenKiosk to lock down the computers so they would function exclusively as catalog stations. OpenKiosk is an open-source kiosk browser released under the Mozilla Public License (MPL) and originally developed to provide a secure, customizable browsing experience for public settings such as libraries, schools, and museums.

OpenKiosk allows administrators to restrict which websites users can access, disable menus and toolbars, and prevent changes to settings. Because it is built on Firefox, it supports modern web standards and runs smoothly even on modest hardware. The interface is familiar to anyone who has used a web browser, which means patrons don’t need extra training to use it.

Using OpenKiosk’s Whitelisting Feature

OpenKiosk Web Browser whitelist page

One of the most essential features of OpenKiosk is its whitelisting capability. OpenKiosk is configured to allow access only to our library’s OPAC URLs and homepage. This prevents patrons from navigating away to other sites, protecting them from potential security risks and keeping the stations focused on their purpose.

Setting up the whitelist is straightforward by editing the configuration to define the exact domains and subdomains that are permitted. OpenKiosk then automatically blocks any attempt to visit non-whitelisted websites or open external links. I also configured the system to launch OpenKiosk automatically when the computer starts and to disable any system menus or keyboard shortcuts that could exit the application or access the underlying operating system.

Integrating Vega Discover as the OPAC Software

WHAM OPAC

Our library uses Vega Discover, developed by Innovative Interfaces, as our OPAC platform. Vega Discover provides a modern discovery layer that makes it easier for patrons to search our catalog, explore collections, and manage their accounts. The interface is visually appealing, responsive on different screen sizes, and accessible to users with varying levels of technical skill. All while being ADA-compliant.

Vega Discover pairs exceptionally well with OpenKiosk because it provides a clean, focused experience without clutter or distracting elements. Patrons can walk up to any OPAC station and immediately begin searching without worrying about pop-ups, browser toolbars, or irrelevant content, and appreciate that the stations are reliable and easy to use.

Benefits and Takeaways

 

Repurposing these PCs has provided multiple benefits for our library. First, it saved us the cost of purchasing new dedicated hardware. Second, it reduced electronic waste by extending the useful life of computers that would otherwise be discarded. Third, it created a secure, maintenance-friendly environment that requires minimal intervention from staff.

Using Debian Linux and OpenKiosk together gave us the flexibility and control we needed without licensing fees or proprietary restrictions. Combined with Vega Discover’s modern catalog experience, our patrons now have a reliable, efficient way to find materials and explore the library’s resources.

Conclusion

Conclusion Infomap

For libraries looking to stretch their budgets and improve public computing, this approach can be a practical solution. With the end of support on Windows 10, many PCs that are unable to be upgraded to Windows 11 can still be useful. By combining Debian Linux, OpenKiosk, and Vega Discover, we created OPAC stations that are fast, secure, and sustainable. If you’re considering a similar project or have questions about configuration, I’d be happy to share more details or hear about your experiences.

Day #3 of Fedora Silverblue


By the third day of using Fedora Silverblue, I already discovered it wasn’t as easy to customize Gnome as in Fedora Workstation, or any other distro with a Gnome Desktop Environment. No matter what desktop environment I’m running, the first thing I always do is install a dark theme, either Adwaita-Dark, Arc Dark, or Greybird Dark, and the second thing I do is install papirus icon. With Gnome, you need to install Gnome Tweaks, if it is not already installed by default. With Fedora Workstation it’s just a simple sudo dnf install gnome-tweaks papirus-icon-theme, but with Silverblue instilling these apps requires you to use rpm-ostree instead of dnf.

Once installed, I was able to customize Gnome the way I like it! I’m still installing apps on my laptop, but so far I’m linking Silverblue so much I’ve installed it on a second laptop. Before you go thinking I’ve already made up my mind, I doubt it will stay on the second laptop long since Pop os 21.04 beta was just released, and I’m very excited to check out Cosmic!
