My name is Skylar Pearce, I have been working as a System Administror since 2013 as well some side consulting work. During my career I have worked with everything from Active Directory and vCenter to configuring routers and switches and phone systems, documenting and scripting my way through the whole thing. I have a Security+ certification and am currently working on my PenTest+. Throughout my career I have gained almost all of my knowledge from blogs like this. It is now time for me to pay it back. Over time I have gathered scripts and tricks over the years that I will share on this site. A lot of the posts here will be mainly reference posts, some will be full on how to’s. I am happy to go into more depth on any other topics I go over here, just make a comment on a post. I will do my best to post once a day on weekdays but as I run out of ideas it may slow down. My WordPress skills are still growing so the site will likely get better over time as I learn. You can reach me at contact@allthesystems.com or on LinkedIn
