From time to time, I have to deal with a minor, incidental, but time-consuming technical problem. Like many people in this field, I used to enjoy it. But it keeps frustrating me whenever I have to deal with the same problem later again, but not soon enough that I remember the details of the solution. To avoid future frustrations, I take notes here.
The intended audience is just for me, so the tips are given without contexts or explanations. But it would be nice if information here could be helpful to anybody.
