Part of our Linux environment was installed and maintained by good-willing amateurs like myself. Terrence upgraded our physical servers to virtual ones. He provided all personal Linux users in the department with a standardised desktop, making sure that everybody&#8217;s wishes were incorporated.

Recruitment agencies sent us expensive &#8220;Linux Experts,&#8221; but none fully understood the complex interactions and how the systems were breaking. Then we found Terrence.
