Beaker Notebook v1.0 released – open-source polyglot data science web app

1) Beaker is language neutral from the ground-up, and not only can you mix languages, they can communicate. IPython does not have good support for multiple languages in the same notebook. And the backend is still pretty python-specific. Jupyter is working to address this, but I don't know how far along they are or how far they are going to take it.

2) Beaker UI has some nice new features: eg hierarchical sections that you can open and close, and one-click sharing.

3) Beaker is highly configurable and extensible via plug-in APIs so you or your organization can add your own languages, media types, security and authentication protocols, data sources, formats, menus, etc, and not have to worry about merging when a new version comes out.

4) Beaker has a great R backend.

5) Beaker is hiring! See http://www.twosigma.com/careers/position/936.html and http://www.twosigma.com/careers/position/935.html

compare:

1) Both have the same notebook and cell document metaphor.

2) Both are Open Source.

3) Both are great tools that I love.
