The Ten Commandments of Scientific Coding

1. Thou shall use version control.

2. Thou shall comment thy code.

3. Thou shall use existing libraries whenever possible.

4. Thou shall try to unit test.

Copy nbflatten.py to somewhere on $PATH. Then, in the root of a git repository, run these commands:

echo "*.ipynb diff=ipynb" >> .gitattributes 
git config diff.ipynb.textconv nbflatten.py

When you change a notebook and run git diff, you'll see the diff of flattened, simplified notebooks, rather than the full JSON. This does lose some information (metadata, non-text output), but it makes it easier to see simple changes in the notebook.

This doesn't help with merging conflicting changes in notebooks. For that, see nbdiff.org.

IPython Notebook on an SGE cluster

This guide documents how we set up an easy workflow for using the IPython Notebook on our compute cluster managed with Sun Grid Engine (SGE).

Summary: We provide a script to the cluster users that runs qrsh to schedule an ipython notebook job using SSL and password protection.

Notes on my Raspberry Pi server config

This describes how I installed and configured my Raspberry Pi model B (512MB).

The Pi is mainly used as SSH jump host, IRC client, Git server, backup fileserver, etc. It doesn't need stellar performance, it just has to be cheap, low in power usage, and secure.

Viewing IPython notebooks in GitLab

GitLab is open source software to collaborate on code (a GitHub clone to run on your own server). Clicking a blob (a file in a repository) in GitLab shows a nice rendering if GitLab supports the file type (e.g., images, Markdown documents), or its content as plain text otherwise. The patch described here adds support to GitLab for rendering IPython notebooks (.ipynb files).
