Breaking the closed source code barrier

Open source coding is the practice of making the source code of programs publicly available for reading and modifying. In scientific modelling, habits and attitudes towards open source coding vary between disciplines and across institutes. In this seminar and open discussion, David Katzin will share his experience with open source modelling in the domain of greenhouse horticulture. Greenhouse models have been developed and published since as early as 1983, but the first open source model appeared in 2017. Using this example, we will discuss the factors that facilitate and impede open source coding: what are potential benefits and drawbacks? What are the attitudes toward this practice? How does open source fit within the general framework of open science? And what steps should we take to make our own code open source?
