Happy Anniversary! Like others here, Slackware was my first distro. I called it out in a blog post of mine a long time ago:
"All the “legit” people were using Linux so I spent a week downloading the different packages for a Slackware install and put them all on 3.5” floppies only to have the install fail. I should mention that up until this point I had basically zero Linux experience. Luckily for me there was Cheap Bytes which was a site that would burn everything to a CD and mail it to you for a small fee. A few weeks later that old 133Mhz Windows 95 computer was a lean and mean Linux box. I can still remember the panic when I saw that “darkstar login” prompt come up. What the hell had I done? As I said earlier, I was all in."
