Report: the unhappiness of software developers

The present document contains an in-progress summary of the data that we obtained while running a large questionnaire in 2014. We conducted the study for (1) estimating how happy are software developers, (2) finding the major causes for happiness and unhappiness of software developers, and (3) finding the major consequences of happy and unhappy developers while they develop software. We made this report freely accessible as a way for thanking our participants for their effort.
