This year JuliaCon is fully on line and for free!
I am co-authoring two talks during this event.
Let me start with one that is not directly DataFrames.jl related, but I think it is a nice showcase of situations where Julia shines. It is prepared with Przemysław Szufel, where Przemysław shows how one can build a large scale simulation of transportation networks using Julia. You can find the details here.
The second talk is a tutorial is about DataFrames.jl indexing and you can find more information about it [here][https://live.juliacon.org/talk/8SFYHK]. In particular the materials that I will cover during this talk are available for download on GitHub here.
Finally, if you interested in data management related ecosystem in Julia, make sure to join Julia & Data: An Evolving Ecosystem that is organized by Jacob Quinn for a discussion about its current state and future directions.
