I spent most of POSSE Day 3 being lost – and not necessarily “productively”.

After spinning my wheels for a while and aimlessly looking at the code for Measure, Aparna and I finally decided to try to add a tool tip to the slider in the sound tools. By lunch we had broken Measure. We finally discovered that the issue is that, while the buttons are Sugar graphics elements, the slider is a GTK element. (Or maybe Kristina told us that – I can’t remember.) So I spent some time looking for where the toolbarbutton is defined. (The Sugar graphics elements are at /usr/lib/python*/site-packages/sugar/graphics – Google knows all…)

After looking at that code, I decided that the “best” fix would be to create a Sugar-based graphics element. I haven’t started on that because it would require changes to Sugar code, not just Measure code, and that seemed like a much bigger task – both coding-wise and process-wise. I may take a look at it later.

I have to do some thinking about how “unproductive” a day this was. It was certainly unproductive in terms of code. However, it was probably productive in terms of realizing what my students may go through while trying to do this next semester. I’ll have to think about what I’ve learned while doing this that I may want to help them with. Even harder will be trying to decide how much to help them. Is there something important for them to learn in spending a stretch of time being “unproductive”?
