Re: What is your age and what do you use ubuntu for?
Use Ubuntu for: Everything. @ Work I use Ubuntu for research and study including surfing the web and online training, emails, testing OSes and software via LXC and KVM hosts (usually ubuntu or debian), for network design with Dia and writing configs and scripts for Linux servers and cisco/juniper network equipment.
@ Home Ubuntu has my desktop and 2 servers. Anything that a windows user does, I do it on my Ubuntu desktop. I don't have enough time for games. If I did, I'd use Ubuntu. The desktop also handles my hobby of tuning into ham radio bands and watching the psk31 and rtty traffic with fldigi, and I use JackMixer to clean up some voice signals (that's just my odd-ball idea that seems to be helping with some weak signal reception). One Ubuntu server is a file server (via samba for the housemates and via sshfs for myself) where I keep all the households movies, TV shows and music safe, along with providing a backup location to the household. The other Ubuntu server is my virtualisation host, hosting lxc/ubuntu containers that provide dns, dhcp, nagios and syslog. The vhost also has a Windows 2012 test system that I am comparing to Samba4.
I dream of a world where our lives can remain private, and our technology can remain open to all.
