What are notebooks?A notebook combines the functionality of

a word processor — handles formatted texta "shell" or "kernel" — executes statements in a programming language and includes output inlinea rendering engine — rendersHTML in addition to plain text

Notebook benefitsA single document that combines explanations with executable code and its output — an ideal way to provide:

reproducible research resultsdocumentation of processesinstructionstutorials and training materials of all shapes and sizes

A digital learning environmentfor computational thinking

What is Jupyter notebook?First notebook: Mathematica 1.0 in '88Jupyter notebook is a part ofProject Jupyter, a nonprofit to

develop open-source software,standards, and services forinteractive computing across dozens of programming languages

beginning with Julia, Python, R, and now over 70 languages, including Dyalog APL

Online notebook serversBenefit: nothing to install

you may need to sign up for an accountTo protect servers, host may place restrictions

or run in a sandbox with limited connectivityNotebooks can execute any code

all code is run on the host serversame privileges as local execution

https://dyalog.tv/



35



Static notebook viewersNotebooks are stored as .ipynb files

.ipynb files are in JSON formateach code cell may include output from the last execution

You can share an .ipynb fileanyone with a local notebook server can view it… but of course cannot execute anything new

Many online systems have viewersGitHub's file previewerProject Jupyter's nbviewer.jupyter.org

https://dyalog.tv/



36



Exported notebooksNotebooks can be exported to many standard

for example HTML, PDF, and LATEXSome formats require 3rd party plug-insExported notebooks are static

expressions cannot be re-executed
