I'm 22 and I've been using Slackware since 2014. I started using Linux when I was about 12, and by the time I got to Slackware I never looked back because it's rock solid and never breaks, even compared to other """stable""" distros like Debian, which I am blessed to have been able to leave behind me for all these years.

That means you were 17 when you started using it. Why did you first move to Linux and how did you first hear about Slackware? Did you find Slackware difficult to learn?

My first contact with Linux was in 1999 (with 16y) with a Slackware 4.0 CD i got from a Magazine, i installed in my home computer a 486 DX2 with 8mb Ram, and my Father almost killed me becouse i did not understand how partition works and i got all his windows documents wiped out.

Later when i learned from my mistake i moved to conectiva and redhat Linux, and in 2001 i got my hand in a Slackware 7.1 server and got in love again, till this day.

Both your faults. He should have had a backup!

I initially tried linux after meeting a guy that was triple booting OS2/warp, linux and one of the BSDs. After doing some research I decided if I was going to learn a new OS I wanted it to be the 'coolest one' lol

My search somehow brought me to Slackware so I installed it. I think it was around 6,7,8... something like that (around 1995). I messed around with Gentoo and a few others but honestly they all had more problems than windows. Slackware has been solid and simple so I stuck with it.

In the 40+ category :)

1995 must have been in the 3.0 or earlier category, 7.0 didn't come out since 1999 (and 5 or 6 never existed, Pat jumped from 4.0 to 7.0).

i first used redhat in the days of dial-up as a web proxy server and mail server, then when redhat went "paid version" on recommendation I switched to slackware, and haven't looked back. I use others like debian (for raspberrypi) and ubuntu (users who want a cheap replacement to windows), but slackware has been the best time investment, knowledge wise, and i use it for servers, and alternatives to windows desktop where I am available for support. The only application missing (apart from an old windows game i like) is an open source accounts software that works with uk current tax rules. For that I still have to use m$windows, so I dual boot several machines. Slackware also has an advantage that it doesn't do anything unless you tell it to, so that on limited broadband I don't have to worry about automatic updates using up data allowance, like other OS's do.

Same. Red Hat 9 was an amazing distro, I loved it. I even have the Red Hat Bible(good book). I was comfortable with Red Hat; I credit RH with getting me out of my comfort zone when Red Hat morphed into RHEL. I didn't want to pay for a subscription. I started Slackware about 15 years ago with version 10.0.

I first moved to Linux at a very young age because my father purchased one of those "Windows Vista Capable" machines that were really meant for XP. Instead of dealing with it's problems, I googled "free operating system" and that's how I ended up on Ubuntu 8.04. I switched to Debian shortly after and used it until 2014.

As for Slackware, my friend told me about it when I was complaining that Debian was breaking all the time, and that I was frustrated with it's package management. Truth be told, I have never found Slackware to be any more difficult to learn than something like Ubuntu. In fact, while this may be a bit controversial, it's reliability is why I've recommended it as a first and last distro to many people who are still using it today. The documentation is excellent, and I'm not much of a Linux evangelist as some are, but rather, I see it as something for people who know how to read. That said, I still don't believe it's that complicated, especially when it has such an easy installer.

1999... nobody think about backup in my house that time. I think first time i made a backup was when i got a CDRecorder years after that.

I started on Red Hat 6, which a friend installed for me. But I later bought the Red Hat 9 Bible because I saw it going half-price in a local book shop. It came with an installation disc of course. After that I used several different distros. I'm new to Slackware but I find it an excellent fit temperamentally.

My first Slackware install.
 

Found the actual evidence: Walnut Creek Linux Toolkit, June 1997. It was actually Slackware 3.2.

This 6-disk set had 5 distributions included: Slackware 3.2, MCC 1.0, Debian 1.2.13, GNU/Debian, Mini-Linux.

Although I already had unix experience, I had never tried Linux before. I failed to install Debian and MCC (fail to boot after install) as dual boot on my Win95 Pentium 200mmx, but Slackware booted ok and gave me a login prompt. Still remember that moment. :) That's how I started using Slackware.

I forgot to mention (hazel may be interested), that my first proper introduction to unix was at ICL in Reading (REA02) in '92-3 where I worked in the directories division, in-between doing my degree. That was on a dual processor 386 ICL DRS300 development box, later a DRS6000 both running a unix flavour, and also a "mainframe" (can't remember which, running officepower) for which I had a green screen terminal, and a colour terminal.(great privilege) That was when windows 3.11 was only just coming out, and we used msdos, or drdos, and unix was so much better. (still is)

I still got my Walnut Creek Linux Slackware version 3.0 2-CD set too.
I did use Slackware before that, but those releases were downloaded on multiple floppy sets, this was the first "real CD" of it I bought (and regretted it soon after as 3.1 "Slackware96" came out, with the 2.0 kernel). I got official CD boxes of most versions since 8.0 too, until after 12.2 my work stopped using Slackware and I had to learn other distro's (like openSUSE, CentOS etc.).
Never stopped using Slackware at home, though.
