I sometimes get disproportionately frustrated at technology issues at my place of work. We have an IT department with some really nice guys who work with us, but they seem to have a model of changing settings and doing fancy fancy high tech "re-imaging" of the computers on our network and every time they do, something else doesn't work the way it is supposed to. Today I was trying to teach in our computer lab, but I couldn't get the projection system to work. I ended up doing a low tech version of the lesson that pretty much sucked, but it is what is …
The projection system got fixed extremely quickly after my class was done, but from a teacher's point of view getting a projection system fixed and working AFTER you no longer need it is kind of not as exciting a thing as it sounds like it might be.
