Welcome to the "Lankku" Tradition

At the GPT-Lab, Pori unit of Tampere University, we have a unique tradition known as “Lankku”—a tangible representation of the culmination of years of dedicated research. This tradition involves the ceremonial nailing of a completed dissertation to a wooden two-by-four plank, marking the final step in the doctoral journey.

What is the “Lankku”?

The “Lankku” is more than just a piece of wood; it symbolizes the perseverance and commitment of our doctoral students. Once a dissertation reaches its ultimate form, it is ceremoniously attached to the “Lankku” using nails—a practice that reflects both the end of an academic endeavor and the beginning of a new chapter in the researcher’s career.

The Historical Significance of “Lankku”

The tradition was initiated by our software engineering research group at the Pori unit. Each dissertation, after years of meticulous work, earns its place on the “Lankku,” serving as a physical reminder of the hard work and dedication required to achieve academic excellence.
Legends say that the “Lankku” is an ordinary Finnish two-by-four, but with certain special qualities that suggest it possesses a magical “design rights” charm. For each nailing ceremony, three nails are said to be chosen from a mythical forest, hoping that at least one will be functional. A fully Finnish hammer, though made in China, is used for this ceremonial nailing.

At GPT-Lab, we take pride in this tradition, as it represents the dedication, hard work, and success of our doctoral students. The “Lankku” serves as a powerful symbol of our commitment to academic excellence and the advancement of knowledge in the field of software engineering and generative AI.
