I was organising this colloquium from January 2012 till August 2013.
During that time, it was a relatively stable weekly event, only occasionally deviating from the schedule or merging with other events.
In my design, there were two types of colloquium presentations:
PEM (Programming Environment Meeting)
— usually an invited talk by an external expert about a topic relevant for the SWAT team, or a presentation by a SWAT member intended for a broader public.
SEM (Software Engineering Meeting) — an internally intended talk by members of SWAT to discuss their work in progress with colleagues.
The last organiser before me was Bas Basten, the next one after me was Atze van der Ploeg.
Information about older talks was semi-automatically extracted by me from the backups of Jurgen Vinju.
