作者介紹
Scott Empson is enjoying being mostly retired after working for more than 30 years as a teacher--4 years in the Alberta K-12 public school system and 27 years as an instructor/program chair at the Northern Alberta Institute of Technology in Edmonton, Alberta, Canada. He taught a variety of technical courses in Cisco-related topics and soft-skills courses like professional development, organizational behavior, and leadership. Scott also worked with students as they moved from being students to IT professionals through internships and co-op classes. He has a master of education degree along with three undergraduate degrees: a bachelor of arts, with a major in English; a bachelor of education, again with a major in English/language arts; and a Bachelor of Applied Information Systems technology, with a major in network management. Scott lives in Edmonton, Canada, with his wife, Trina, who is still processing that he gets to stay at home while she still must go to work. His children have left the nest and are living their best lives. Scott is now upset that he must do all the yardwork, including shoveling snow during Canadian winters.
