I liked Unix from the first time I saw it, in the early ’80s when I took a class in the summer at my dad’s community college.
I’ve been using Linux for a good long time — I remember when the move the 1.3 kernel was in the offing. I’ve installed it on a ton of machines over the years. I ran my own IMAP server in-house for a while, until webmail made that stupid. I’ve got multiple Linux servers in my house, and a passel of them at work.
For years I worked on Unix boxes; some of my earliest Java coding was done on a Solaris box. But Solaris, like BSD, is too niche to use as an everyday platform on commodity hardware. So, half my hard-drive is an Ubuntu installation, and that’s where I do most of my work.
