Re: [jupyter] JVM Magics

I'm curious how magics mesh with proposals like
https://github.com/jupyter/enhancement-proposals/pull/26.

 Hey all,

 A couple weeks ago a bunch of Scala kernel maintainers came together
 during the Notebook Enterprise Summit .
 One of the topics of discussion was making consistent magics across the
 various Scala & JVM kernels. Notes and proposals are here:
 https://github.com/nteract/nes/tree/master/jvm-kernel-magics

 Ryan Blue created jvm-magics as a result of this:
 https://github.com/rdblue/jvm-magics

 Please check it out if you're interested and post issues. When ready,
 we'd love to see this land in the jupyter org to support similarly to
 jvm-repr.

[jupyter] Gateways 2019 Call for Participation (Abstracts due April 29; Full submissions due May 6)

[Katherine Lawrence]

Call for Participation: Gateways 2019 (September 23–25, San Diego, 
California) is now accepting submissions of papers, demos, tutorials, and 
panels (2–4 pages) on the topic of gateways for science, engineering, or 
other disciplines. Gateways are user-friendly interfaces to scientific 
computing, data, and other domain-specific resources to support research 
and education. 

Topics may include their design, use, impact, development processes, 
sustainability, best practices, or any other aspect that you think fellow 
gateway creators or users will find interesting to learn. We also welcome 
educational topics directed toward the next generation of gateway creators. In 
addition, this year Gateways 2019 is co-located with the eScience 
 conference. The two conferences will offer 
shared sessions and connected registration.

Abstracts are due April 29, and full submissions are due May 6, 2019. A 
poster session deadline (open to all attendees) will be August 15. Read 
more details in the Call for Participation:
