I am also a computer science professional with an established career of 20+ years focusing on system administration. After leaving the enterprise computing world I embraced open source technology, becoming a trainer in the Linux operating system and promoting its use as a desktop computer environment. I am the founder and president of the Puerto Rico Linux Users Group (PRLUG).

Please join me in starting the PRLUG and bringing awareness of open-source technology. We will schedule Saturday workshops that will focus on Linux installation, basic administration, and use as a desktop system; these workshops will be taught by PRLUG members starting February 2019.
