Scala in 2018: SF Scala panel with Rod Johnson (by FunctionalTV).
Rod Johnson, the creator of Spring, gave a keynote at ScalaDays 2013 outlining his vision of Scala in 2018 and what should we do as the Scala community to make it successful. Here, SF Scala brings together well-known community members, Jorge Ortiz, Paul Snively, James Douglas, Ity Kaul, and Brian McKenna on stage with Rod Johnson to debate the future. Alexy Khrabrov, the SF Scala organizer and founder of funconf.org, moderates.
The Karmic Social Capital is an iterative computational process which evolves in social network time, changing with every new edge. You need to play back the complete history of the social graph’s growth to compute it. Changing the parameters involves frequent loading of the original dynamic graph and recomputing the social capital.
We implemented KSC in three functional languages:
The implementations are on github as respectively:
Twitter has provided a permission to publishing the derivative graphs of our working set of 100 million tweets, from about 5 million users over 35 days. We provide a 100 thousand tweet subset and will add the full data.
The current timing for loading the graph, computation, and saving it are as follows:
