Welcome to DailyLinux.com
Thanks for visiting DailyLinux.com! This is a personal blog that started over 20 years ago in January 2004. Despite the ambitious "Daily" in the name, this has never quite been a daily endeavor. What started as aspirational daily content quickly became weekly updates, and then life (and paying work) took priority, making it more of a "whenever inspiration strikes" kind of place.
What This Site Is About
This is simply a place where I share Linux and UNIX-related things that interest me – tutorials, experiences, discoveries, or anything I think might help fellow Linux enthusiasts. It's always been driven by curiosity rather than rigid schedules or themes.
My Background
I've been working with Linux since the Slackware 3 days in the 1990s and have been certified in both Red Hat and SUSE systems (though I've let those certifications expire – my most recent SLES Certified Administrator expired a couple of years ago, and I'm looking to get that back).
In my professional life, I've had the opportunity to teach basic Linux courses for technical support organizations, as well as specialized courses on connecting iSCSI and Fiber Channel storage to Linux and UNIX hosts. I've also covered topics like establishing Linux NAS servers and connecting Linux clients to Windows-based storage solutions.
Looking Forward
While there are certainly many people out there who are smarter and have more experience than I do, I believe there's always value in sharing knowledge and different perspectives. If you're interested in following along, you can find me on X at @DailyLinux.
Want to Contribute?
If you have Linux or UNIX experiences, discoveries, or tutorials that you think others might find interesting or helpful, I'd be happy to consider them for the site. Feel free to message me on X, and we can discuss setting you up as a contributor.
Thanks for stopping by!
