Most of the software I use on daily basis are Free and Open Source.
I’m using CentOS 7 on my Home server and Archlinux on my Laptop. For my Raspberry Pi, I’m using Raspbian ( Debian based). Other then these, I also run other distributions of Linux and BSD in virtual machines.
I’m using i3 Window Manager standalone. As I spend large amount of time in Terminal, naturally, I use a lot of terminal utilities, including but not limited to tmux, moc, ranger. Vim is my choice for a text editor. My dotfiles are available here.
I use Chromium for browsing the web and for emails I’m using Thunderbird.
I also use docker a lot. I’ve written some dockerfiles about which you can read here. I also have some personalized dockerfiles, source of which can be found here.
I’ve also written some fun little bash scripts which may or may not be of any practical use, about which you can read here.
All my web servers are running Nginx exclusively.
