As you can see the article is talking more about networking related positions if you find the keywords in the list like ON CALL, NOT LIKING TECHNOLOGY, SWITCHES, ROUTERS, END USERS, LONG HOURS, FRUSTRATION, TURNING OFF CELLPHONE, MULTITASKING.

As you can see developers or programmers are not required be be on call, so you know this list is mostly for computer support, networking administration and computer systems analysis positions.
