Linux Training Academy

I’ve used Linux on my personal computers since as early as 1995 or 1996 and started working with Linux professionally in 1999. I was immediately drawn to Linux. It was love at first sight for me.

The Linux design and philosophy made total sense to me, and I wanted to learn everything I could about it. I started using Linux daily and set out to get a job using Linux.

Since then I’ve used Linux in almost every type of situation imaginable: at large well-known corporations, at small privately owned companies, at a startup, at a security firm, at an airline, and at a university supporting researchers.

I’ve run Linux on hardware, in virtual machines, in containers, and in the cloud. I’ve done so many things with Linux it’s hard to list them all. Along the way I’ve written a few books and taught a few courses on the subject. Do that for 17+ years, and you’re called an “expert.” 🙂
