Jason Welsh started experimenting with Linux back in 1994 when it was still packaged on floppy disks. Over the years, he has run just about every flavor of Linux there is as well as a few years trying out FreeBSD.

He has been administering Solaris and Linux systems professionally since around 2003, supporting everything from Linux running on the server hardware to storage to VPNs and firewalls. He’s always on the lookout for new and exciting things to try out in his home lab, which runs a Proxmox server. He’s tolerant of all Linux distributions, but the current favorite is Arch or Manjaro Linux.
