I started in the mid 90's with Slackware, however that statement isn't all it seems. I was professionally trained on Unix starting in 1987, so I was well educated in 'Nix long before Linus did his big post. Starting with Linux was just a matter of learning the differences way down in the root tree. I had a parallel machine with Slack for several years as the OS developed and dumped WinXP for general use when Red Hat 7.0 was released, whenever that was. Never ran Redmond products again. Today I wouldn't even know how to boot Win11.
