Welcome to PC✗3
Hi, I’m Stefan Pejčić. I am a virtualization architect, system administrator, WordPress plugin developer, cPanel partner and Python developer.
In my 10+ years of working in IT I’ve concluded one thing:
technology is easy, it’s the people that are hard.
Everybody takes IT folks for granted, only noticing them when something is not working. And when those situations happen, we either come up with a quick solution or use a strategy that worked in the past. PCx3 is a blog that provides exactly that: How To's and hacks that worked for me, and hopefully they'll help other sysadmins as well.
Thank you for stopping by.
