Presentations

A few presentations that are recent or otherwise interesting.

  1. [fnrPPT] Lutz Prechelt. Das Forum for Negative Results: Warum wir Forschungs-Misserfolge nicht totschweigen sollten.
    Presentation (in German) in the Potsdam n_space kolloquium regarding the Forum for Negative Results, 2012-01-25.

  2. [sbstypePPT] Lutz Prechelt. Types of Cooperation Episodes in Side-by-Side Programming.
    PPIG always has a playful contest of some sort. In 2009, PPIG was in Limerick, Ireland, so, unsurprisingly, the contest was about "The best Limerick embedded in a conference presentation". This motivated me so much that I sat all night rhyming Limericks until I had one after each slide of my presentation, each summarizing that previous slide. I won the contest. The prize was a book of Limericks.
