I came across Linux sometime in the late 90's. It was free (as in pricetag, which is all I cared about at the time) and different so I was curious. The PC I was using wasn't mine so repartitioning wasn't an option but I found some ready to go boot from dos linux distro and gave it a go. And I loved it! And still do.

I started first in 2012-ish with Linux. That’s when I first heard of it, and decided to spin an VM with Ubuntu 12.04. Though initially I didn’t use it in real hardware for sometime, eventually I did install Fedora and been pretty happy ever since. Nowadays mostly use openSUSE and Arch.

Windows. More specially a netbook with vista, that ran so incredibly slow ot of the box that it pushed me to install linux. Technically i used Firefox before that, but that was when Firefox was the de facto standard in Germany, so i didn't care about FOSS.

For me those products are:

• Linux
• Firefox
• Bitwarden
• Libreoffice

For me-

• Linux
• F-Droid

Blender 2.9.3 LTS

First foss product I remember using was VLC, but what made me start seeking out Foss was F-droid with how I got tired of constantly trying to find something without unnecessary permissions, ads, or IAP.

That was what made me understand the true value of foss, and not just because something isn't paid with the intent of profiting doesn't mean it is worse. It can sometimes be much better and more respecting of your privacy with how hungry for telemetry companies are these days.

Apache Web Server

VLC but it wasn't love at first sight, but it opened a whole new world of FOSS to me

To this day I still don't know why the fuss about VLC, I prefer MPC-HC

Funny enough it was Windows.
Year of our Lord 2015, Microsoft was pushing for Windows 10, I was using 7 and wanted to keep doing so. One of the last updates completely broke my system, so I said "fuck it", backed up my files and installed Ubuntu.
From that moment on I gradually abandoned proprietary software at the point that today I live almost completely on FOSS.

Firefox for sure.

It was Mozilla for me back in 2000. I gradually replaced all the proprietary apps I was using on Windows with FLOSS alternatives and then finally made the mover to Linux around 2010. The only closed stuff I use now is an iPhone and I despise it.

Postfix! I worked at an E-commerce company that sent newsletters(spam) through shitty Windows SMTP servers. Looking for speed and some other neat things (DKIM and modify headers) I setup postfix on Debian and I guess this system is still running. Quickly after that I explored NGINX as a reverse proxy for yet again shitty Windows IIS webservers. This was my entry to open source and Linux in general.

Probably Mozilla.

For me it was Python and C development on Linux. (So Anaconda.) I was pretty impressed by how much you can do with free software. Before I would have thought scientists would use expensive proprietary software for calculations. Later I learned that they sometimes still do, but many write their own code using work from others in the field who released open source software.

Emacs.

No really, it was like 1989 and I had to learn Unix systems for classes, and this white haired Emacs advocate convinced me to try it.

Crostini (The Chromebook Linux solution)

The very first FOSS software I used was red hat Linux. My dad brought home a copy of it and left it laying next to our copy of windows. Next time I had to install an OS I found it and tried it. It was terrible. Didn't do anything I wanted to do. Put windows in the computer.

@graphito Red hat Linux back in 99. Ran X11 Gnome with Metacity, bash and emacs. Still using Linux today. But Im on Arch with zsh, kde/plasma Wayland and NeoVim. Probably the only thing that I still use now from '99 is less 😃

Signed up for Ubuntu free CD. Got 10.04 LTS. Was such an improvement from vista on a core 2 duo and 3gb ddr2. Only moved complete to linux in 2019 after years of tinkering with couple RPis and getting the hang of using linux.

I'm so old, when I started, software was either part of the operating system, or we had to get it for free, as source to compile it locally. Yes, there were commercial software packages for some applications, but most of the everyday stuff (editor, file browser, file transfer programs, multi-user online games and their clients) was open source. And many of us contributed, me included. I wrote Gobelin, an NNTP news reader/filter/aggregator, and Connector, a frontend for multi-user online games.

"open source" is not a product, it means that you get access to the source code

Well I was going to say Foxit PDF Reader, but my memory failed me. It was just free. So probably Firefox, though I had no concept of FOSS at the time and kept giving up on it and going back to Chrome due to autofill being pretty seamless across the mobile/desktop apps. But I'm all in on team Firefox now and have really enjoyed finding new apps to self-host in particular. Currently trying (and failing) to stand up an instance of Cryptpad.

I've been exclusively on open source since at least 22 years now, but the one thing I always use to lure people to Linux is the bling, then they stay for the awesomeness.

KDE used to have awesome bling which I regularly used for that but lately they've been taking more and more of it away. Now event the 3D desktop is gone and it's mostly just a normal desktop, not really something to lure people with, unfortunately

Slackware V3.1 in 1996. I bought a thick reference book that came with the installation floppies. Installed to an IBM Aptiva, forget the model and processor.

Linux. I signed up with my first proper ISP as a kid in the '90s. The service included a shell account on their Linux server accessible by telnet. I thought it was really cool and decided to see if I could run it on my own computer, and to my delight, I could.

Android. I grew up with old phones where you chased the new trend but you always lost something or you where limited to what manufacturer’s limited idea. This one has good ring tones. this has amazing camera. This got real games. This one has music buttons. This one has apps(not really apps but back then impressive for a phone)

Updates did not exist what you got in box was what you got. suddenly this device comes out where you could do anything.

I could install real Linux, community supported software and made it better. This was my gateway because why should I accept to pay money when the moment I given you money you moved on and forced me to buy next stuff but forgot the great things you done?

Likely not the best for merch: my first FOSS soft was DJGPP, in the DOS era. Tried to use BSD before that, but it was like 200 floppies, and never got it to work.

The thing that fully sold me though, was installing some drivers on RedHat 5.1, and seeing how "they recompile themselves! 🤯"... so dunno, was it rpm? make? gcc? kbuild?... hard to tell now.

Next thing was getting a second PC, installing a bare bones system, going into bash, ls /bin, and going man [everything].

I might still have some "man bash" stickers somewhere, used to have them on a few laptops over the years.

Stumbled upon Novell Suse Linux in the software section of Best Buy. That sent me down the rabbit hole. I actually got caught up in the world BSD specifically DesktopBSD. I was amazed by all the “free” software options.

Ubuntu 9.04. Jaunty Jackelope in 2009. Started by dual booting my Windows laptop. XP mainstream support ended that year, and I didn't want to upgrade to Vista, nor could my laptop handle 7.
