Etc Etera

The answer depends on what you want to call a programming language. Strictly spoken, XML and HTML and CSS aren't...

The question in the headline asks something completely different than the question in the poll.

I was in my twenties, in the early 1990s, when I did "my first Linux install" (an early SuSE Linux). I gave it up soon, continuing to use OS/2 (later its eComStation refresh) for serious stuff and Windows for games, and moving to Windows exclusively on the desktop a decade later when holding on to OS/2 on the desktop had finally ceased being a viable option.

But I was in my fifties when I actually "started using Linux". That was a year ago, when I finally couldn't avoid the tedious task of decommisioning my last active production server that still ran on OS/2 (eComStation) and building a Linux machine to do its work. Because of Windows 10 and my dislike of it that went even deeper than my general dislike of virtually anything from Microsoft I so far had had something to do with, I decided to try Linux at the same time, too. A few months later, I've moved virtually everything to Linux at my home & home office, and the only thing I ask myself is why I didn't try that earlier.

In my job, though, unfortunately it's still mostly Windows on the desktop, while the software I write usually runs on Linux servers.
