I’ve worked from home6 out of the last years. The4 years when I worked out of an office were when I was managing people, or when I worked from an office part of the week. A motivated programmer will get more done at home than at work because of the lack of interruptions. Progress is also fairly easy to measure, so managers tend to let programmers work from home, at least on an ad hoc basis.
