Hands down the best and most used tool in my portfolio. Well done, guys!
Does anyone know if there's a plan to introduce multi-kernel support in single notebooks like what Zeppelin does? Not that I have a strong preference for it but it appears to hold a lot of appeal in Spark-like environments where not all packages are available in Pyspark and you need to move between native Scala/spark and Pyspark.
We are actually working on improving the polyglot support in Jupyter by porting/merging work from Beaker Notebook (http://beakernotebook.com) into Jupyter and especially into Jupyter Lab. This new effort is called BeakerX: https://github.com/twosigma/beakerx. We have autotranslation working in one direction now, should have multi-way in a couple of weeks.
