Researchers often study dynamic processes of latent variables in everyday life, such as the interplay of positive and negative affect over time.

This paper presents the first experiences of the use of an online open-source repository with programming exercises. The repository is independent of any specific teaching approach. Students can search for and select an exercise that trains the programming concepts that they want to train and that only uses the programming concepts they already…
