Computable content: Notebooks, containers, and data-centric organizational learning

This talk will present:

* the system architecture based on Jupyter as middleware, plus Thebe, Docker, Mesos, Nginx, etc.

* data analytics and project experiences based on delivering _computable content_ at scale

* supporting theory for this pedagogical approach, including Knuth’s _Literate Programming_

* media production techniques that use the video as _subtext_

We will also consider the use of notebooks (Jupyter and others) in an organizational context: how do notebooks help teams share and learn? what impact might notebooks have on developer collaboration that is currently focused on IDEs? The resulting medium provides highly effective tooling for a data-centric organization.

 Jupyter notebooks Regex Golf by Peter Norvig
 oreilly.com/learning/regex-golf- with-peter-norvig
  16. 16. 17 Motivations O’Reilly needed a way for authors to use Jupyter notebooks to create professional publications. We also wanted to integrate video narration into the UX. The result is a unique new medium called Oriole: • Jupyter notebooks are used in the middleware • each viewer gets a 100% HTML experience 
 (no download/install needed) • context as a “unit of thought” • the code and video are sync’ed together • each web session has a Docker container running in the cloud
  17. 17. 18 Motivations Innovators in programming, data science, dev ops, design, etc., tend to be really busy people. Tutorials are now much quicker to publish than “traditional” books and videos. The audience gets direct, hands-on, contextualized experience across a wide variety of programming environments.
  18. 18. 19 Literate Programming, Don Knuth

  21. 21. Notebook Practice
  22. 22. 23 • focus on a concise “unit of thought” • invest the time and editorial effort to create a good intro • keep your narrative simple and reasonably linear • “chunk” the text and code into understandable parts • alternate between text, code, output, further links, etc. • use markdown for interesting links: background, deep-dive, etc. • code cells shouldn’t be long (< 10 lines), must show output • load data+libraries from the container, not the network • clear all output then “Run All” – or it didn’t happen • video narratives: there’s text, and there’s subtext... • pause after each “beat” – smile, breathe, let people follow you Tips learned by teaching with Jupyter For the JVM people: stop thinking only about IDEs, Ivy, Maven, etc. (ibid, Knuth1984)
 BUILD UBER JARS, LOAD LIBS FROM CONTAINER, NOT THE NETWORK!
 (apologies for shouting)
  23. 23. 24 Jupyter notebooks + Git repos provide a low-cost, pragmatic way toward the practice of repeatable science – in this case, repeatable Data Science • executable documents • code + params + results + descriptions • shareable insights Notebooks: a cure for silos
  24. 24. 25 In data science, we see the benefits to teams for shared insights, storytelling, etc. Meanwhile domain expertise is generally more important than knowledge about tools There’s a value for developers to use notebooks in lieu of IDEs in some cases – what are those cases? GitHub now renders notebooks, so they can be used for documentation, reporting, etc. Digital Object Identifiers (DOI) can be assigned through Zenodo, making notebooks citable for academic publication “Sharing is caring”
