The Field Artillery Metaphor

Until recently I kept a loose set of technical skills sufficient to get things done at the office or for my home network. Out of necessity I may have dug a littler deeper into HTML/javascript coding or into the settings for a wireless router. Although my full-time employment over the past several years has set me in the proximity of IT and computer science ventures, I never pulled into a close enough orbit to get the "cred" for a career change. I do have an affinity for the technical side so now is a good time to simply sit down and learn a thing or two, possibly to the extent of getting that "cred."
