Samuel Webb
We are happy to announce Samuel Webb as the Contributor of the Month for Dec 2023. Sam was awarded the COTM of this month for being the man behind the development and maintenance of one of the most downloaded extensions of KNIME Analytics Platform: the Lhasa public plugin extension. A relatively small extension, with just 10 nodes, and yet very popular within the KNIME Community, it provides useful functionalities for model building and table manipulation, like performance scorer and table transformation nodes. By the way, Sam is also the author of the Slack Integration extension.
