LinuxCapable publishes tested installation and configuration guides for Linux users ranging from newcomers to intermediate system administrators. I’m Joshua James, and I run this site independently. Since 2021, I’ve published hundreds of guides covering Ubuntu, Debian, Fedora, Arch Linux, Rocky Linux, AlmaLinux, CentOS Stream, and Linux Mint. Every command is tested before publishing – no fabricated outputs or unverified instructions.
Testing Methodology
I verify all commands across the distros and versions documented in each guide. My testing environment includes Docker containers for quick verification, virtual machines for software installation testing, and bare metal systems for hardware-specific guides like Nvidia driver installation on Ubuntu. When an article covers multiple distro versions, I test each one and document version-specific differences in comparison tables.
Terminal outputs in guides come from actual testing sessions. I may clean up minor version numbers for clarity, but the commands, outputs, and verification steps reflect genuine testing. I don’t document features, flags, or repositories without confirming they exist and work as described.
Content Focus and Specializations
LinuxCapable focuses on server administration, desktop software installation, and containerized workflows. I publish extensively on technologies I use regularly:
- Server security: Fail2Ban on Ubuntu, Fail2Ban on Debian, UFW firewall on Ubuntu, firewalld on Fedora
- Web servers: Nginx security headers, Nginx reverse proxy, gzip compression in Nginx, Apache, MariaDB, PostgreSQL, PHP
- Containerization: Docker on Ubuntu, Docker on Debian, Docker on Fedora
- Network and command-line tools: Nmap scanning commands for beginners, curl command in Linux, grep command with examples
- Desktop software: Google Chrome on Ubuntu, Nvidia drivers on Ubuntu, qBittorrent on Ubuntu
Guides include installation steps, configuration examples, verification commands with expected outputs, and troubleshooting for common errors. When software is available through multiple methods (APT, PPA, Flatpak, source compilation), I document each approach and explain trade-offs.
Who This Site Serves
LinuxCapable targets users transitioning to Linux, aspiring system administrators, and intermediate users looking for distro-specific guidance. I write for people who need clear, step-by-step instructions without assuming expert-level knowledge, but I also include technical depth for users who want to understand why commands work, not just what to type.
Transparency and Independence
LinuxCapable is ad-supported through NitroAds to cover hosting costs. I have no sponsors, affiliate partnerships, or vendor relationships that influence content. When I recommend software or repositories, it’s because they’re the best available option for the documented use case, not because of any business arrangement.
I run LinuxCapable independently. My technical knowledge comes from testing hundreds of configurations across multiple distributions, troubleshooting real errors, and maintaining diverse Linux environments over several years of continuous publishing.
Content Maintenance
I review guides regularly for version drift and deprecated commands. When major distro releases introduce breaking changes, I update affected articles and document the differences. If a guide’s commands no longer work as written, I prioritize fixing it over publishing new content.
Readers occasionally catch issues I’ve missed – a renamed package, a changed default, or a flag that behaves differently on a newer release. Those corrections go into the guide as soon as I verify them.
Report Errors or Suggest Improvements
Version drift and package changes can introduce errors between review cycles. If you find a mistake or have a suggestion, use the comment section on the relevant article. I review all feedback and update guides when issues are verified.
