I’m going to start the 100 days of code again. First, followed the instructions in https://julialang.org/downloads/platform.html and completed installation of Julia 1.0.1 on CentOS 7.5.
Then installed iJulia, a Julia-language backend combined with the Jupyter environment, as below:
using Pkg Pkg.add("IJulia")
Then launched an iJulia notebook in Konqueror.
